The present disclosure relates in general to flexible containers, and in particular, to flexible containers having with easily variable sizing, line-ups of such containers, and methods of making such line-ups.
“[I]f you cannot make pure goods and full weight, go to something else that is honest, even if it is breaking stone.” James Gamble, co-founder of The Procter and Gamble Company, from the mid-1800s. A ‘good’ that is ‘full weight’ is a product with an actual size that is true to its label; it delivers the product according to the listed size. While the quotation provided above is from some time ago, its principle continues to endure as a standard to which product manufacturers should aspire. And, this principle can be applied in many different contexts, including the embodiments of flexible containers described herein.
Fluent products include liquid products and/or pourable solid products. In various embodiments, a container can be used to receive, contain, and dispense one or more fluent products. And, in various embodiments, a container can be used to receive, contain, and/or dispense individual articles or separately packaged portions of a product. A container can include one or more product spaces. A product space can be configured to be filled with one or more fluent products. A container receives a fluent product when its product space is filled. Once filled to a desired volume, a container can be configured to contain the fluent product in its product space, until the fluent product is dispensed. A container contains a fluent product by providing a barrier around the fluent product. The barrier prevents the fluent product from escaping the product space. The barrier can also protect the fluent product from the environment outside of the container. A filled product space is typically closed off by a cap or a seal. A container can be configured to dispense one or more fluent products contained in its product space(s). Once dispensed, an end user can consume, apply, or otherwise use the fluent product(s), as appropriate. In various embodiments, a container may be configured to be refilled and reused or a container may be configured to be disposed of after a single fill or even after a single use. A container should be configured with sufficient structural integrity, such that it can receive, contain, and dispense its fluent product(s), as intended, without failure.
A container for fluent product(s) can be handled, displayed for sale, and put into use. A container can be handled in many different ways as it is made, filled, decorated, packaged, shipped, and unpacked. A container can experience a wide range of external forces and environmental conditions as it is handled by machines and people, moved by equipment and vehicles, and contacted by other containers and various packaging materials. A container for fluent product(s) should be configured with sufficient structural integrity, such that it can be handled in any of these ways, or in any other way known in the art, as intended, without failure.
A container can also be displayed for sale in many different ways as it is offered for purchase. A container can be offered for sale as an individual article of commerce or packaged with one or more other containers or products, which together form an article of commerce. A container can be offered for sale as a primary package with or without a secondary package. A container can be decorated to display characters, graphics, branding, and/or other visual elements when the container is displayed for sale. A container can be configured to be displayed for sale while laying down or standing up on a store shelf, while presented in a merchandising display, while hanging on a display hanger, or while loaded into a display rack or a vending machine. A container for fluent product(s) should be configured with a structure that allows it to be displayed in any of these ways, or in any other way known in the art, as intended, without failure.
A container can also be put into use in many different ways, by its end user. A container can be configured to be held and/or gripped by an end user, so a container should be appropriately sized and shaped for human hands; and for this purpose, a container can include useful structural features such as a handle and/or a gripping surface. A container can be stored while laying down or standing up on a support surface, while hanging on or from a projection such as a hook or a clip, or while supported by a product holder, or (for refillable or rechargeable containers) positioned in a refilling or recharging station. A container can be configured to dispense fluent product(s) while in any of these storage positions or while being held by the user. A container can be configured to dispense fluent product(s) through the use of gravity, and/or pressure, and/or a dispensing mechanism, such as a pump, or a straw, or through the use of other kinds of dispensers known in the art. Some containers can be configured to be filled and/or refilled by a seller (e.g. a merchant or retailer) or by an end user. A container for fluent product(s) should be configured with a structure that allows it to be put to use in any of these ways, or in any other way known in the art, as intended, without failure. A container can also be configured to be disposed of by the end user, as waste and/or recyclable material, in various ways.
One conventional type of container for fluent products is a rigid container made from solid material(s). Examples of conventional rigid containers include molded plastic bottles, glass jars, metal cans, cardboard boxes, etc. These conventional rigid containers are well-known and generally useful; however their designs do present several notable difficulties.
First, some conventional rigid containers for fluent products can be expensive to make. Some rigid containers are made by a process shaping one or more solid materials. Other rigid containers are made with a phase change process, where container materials are heated (to soften/melt), then shaped, then cooled (to harden/solidify). Both kinds of making are energy intensive processes, which can require complex equipment.
Second, some conventional rigid containers for fluent products can require significant amounts of material. Rigid containers that are designed to stand up on a support surface require solid walls that are thick enough to support the containers when they are filled. This can require significant amounts of material, which adds to the cost of the containers and can contribute to difficulties with their disposal.
Third, some conventional rigid containers for fluent products can be difficult to decorate. The sizes, shapes, (e.g. curved surfaces) and/or materials of some rigid containers, make it difficult to print directly on their outside surfaces. Labeling requires additional materials and processing, and limits the size and shape of the decoration. Overwrapping provides larger decoration areas, but also requires additional materials and processing, often at significant expense.
Fourth, some conventional rigid containers for fluent products can be prone to certain kinds of damage. If a rigid container is pushed against a rough surface, then the container can become scuffed, which may obscure printing on the container. If a rigid container is pressed against a hard object, then the container can become dented, which may look unsightly. And if a rigid container is dropped, then the container can rupture, which may cause its fluent product to be lost.
Fifth, some fluent products in conventional rigid containers can be difficult to dispense. When an end user squeezes a rigid container to dispense its fluent product, the end user must overcome the resistance of the rigid sides, to deform the container. Some users may lack the hand strength to easily overcome that resistance; these users may dispense less than their desired amount of fluent product. Other users may need to apply so much of their hand strength, that they cannot easily control how much they deform the container; these users may dispense more than their desired amount of fluent product.
Sixth, when using conventional rigid containers, it can be difficult for a manufacturer to change such containers from one product size to another product size.
Product manufacturers regularly need to change the sizes of their products, by changing the amounts of fluent products in their containers. As a first example, a manufacturer may wish to run a promotion, offering a container with more fluent product, at a particular price point. As a second example, a manufacturer may wish to offer a container with less fluent product at a lower price, to provide a particular value proposition to consumers. These are two common examples, but there are many more. Manufacturers may wish to offer containers with new and/or different amounts of fluent products for many other reasons, such as supply issues, manufacturing limitations, changeover needs, packaging considerations, distribution logistics, regulatory requirements, retailer requests, consumer preferences, competitive responses, market conditions, etc. These product sizing issues become even more complex for manufacturers that have products with many variations in many different markets.
When a product manufacturer offers a fluent product in a conventional rigid container, and the manufacturer needs to change the size of the product, the change usually requires the manufacturer to make and use a new size of container for the new amount. If a manufacturer wishes to offer a product size with more fluent product, then the manufacturer usually cannot significantly increase the amount of fluent product in the original container, because most rigid containers are designed with limited headspaces, which do not allow for overfilling. If a manufacturer wishes to offer a product size with less fluent product, then the manufacturer usually cannot significantly decrease the amount of fluent product in the original container, because there are often limits to underfilling product containers. In some geographies, there are regulations that prohibit manufacturers from underfilling rigid product containers, by a significant amount. Even apart from such regulations, a manufacturer may not wish to significantly underfill a product container, to avoid negative perceptions by end users of the product. For example, even if a manufacturer clearly labels its container with the correct amount of fluent product, if consumers see that the container is significantly underfilled, then the consumers may perceive that the container is not a good value. The consumer may then form a negative association with the brand for that product; this is something the manufacturer wishes to avoid.
Unfortunately, when a product manufacturer offers a fluent product in a conventional rigid container, making a new size of that container can be costly, time-consuming, and challenging to coordinate. Changing the size of a conventional rigid container can be expensive because it typically requires buying a new mold, which, depending on many factors, can cost anywhere from thousands of dollars to millions of dollars. When several new molds are needed, these costs can multiply. Changing the size of a conventional rigid container can be time-consuming because a new mold may take weeks or even months to specify, design, fabricate, ship, and qualify for production.
Changing the size of a product container can be challenging to coordinate because the new size must fit with everything it touches—either directly or indirectly. In manufacturing a container, the container may touch various equipment for making, handling, decorating, labeling, and filling the container. In packaging a container, the container may touch various packaging equipment as well as secondary packaging materials, cartons, cases, and pallets. In supplying a container, the container may touch a wide variety of things, depending on how the container is supplied. When a container is supplied in a retail store, the container touches a store shelf or a merchandising display. When a container is supplied through an on-line retail environment, the container may touch pick bins, handling equipment, and/or shipping containers. In its use, a container may touch a container holder, container dispenser, or container refilling apparatus, among other things. At some point in its use, a container is also likely to be touched and/or held by human hands. For all of these touches, the size of the container must be coordinated to fit. And, of course, the changed product must have an actual size that is true to its label; it must continue to deliver the product in the listed size.
So, although product manufacturers regularly need to change the amounts of fluent products in their containers, doing so can be costly, time-consuming, and challenging to coordinate; as a result, when using conventional rigid containers, it can be difficult for a manufacturer to change such containers from one product size to another product size.
The present disclosure describes various embodiments of containers made from flexible material. Because these containers are made from flexible material, these containers offer a number of advantages, when compared with conventional rigid containers.
First, these containers can be less expensive to make, because the conversion of flexible materials (from sheet form to finished goods) generally requires less energy and complexity, than formation of rigid materials (from bulk form to finished goods). Second, these containers can use less material, because they are configured with novel support structures that do not require the use of the thick solid walls used in conventional rigid containers. Third, these flexible containers can be easier to print and/or decorate, because they are made from flexible materials, and flexible materials can be printed and/or decorated as conformable webs, before they are formed into containers. Fourth, these flexible containers can be less prone to scuffing, denting, and rupture, because flexible materials allow their outer surfaces to deform when contacting surfaces and objects, and then to bounce back. Fifth, fluent products in these flexible containers can be more readily and carefully dispensed, because the sides of flexible containers can be more easily and controllably squeezed by human hands. Even though the containers of the present disclosure are made from flexible material, they can be configured with sufficient structural integrity, such that they can receive, contain, and dispense fluent product(s), as intended, without failure. Also, these containers can be configured with sufficient structural integrity, such that they can withstand external forces and environmental conditions from handling, without failure. Further, these containers can be configured with structures that allow them to be displayed and put into use, as intended, without failure. Sixth, these flexible containers can be configured with easily variable sizing, allowing a product manufacturer to change a product's size with less expense, in less time, and with less coordination, when compared with conventional rigid containers.
In a first set of embodiments of the present disclosure, a line-up of flexible containers having similar constructions can hold different amounts of fluent product at similar fill heights. This line-up of flexible containers can comprise a first disposable self-supporting flexible container and a second disposable self-supporting flexible container. Any or all of the containers in the line-up may or may not be configured for retail sale. The first container can have: a first product space construction that is based, at least in part, on a first folding pattern; a first external amount indicium that indicates a first listed amount of a first fluent product that is being offered for sale with the first container; a first actual amount of the first fluent product, disposed in the first product space, wherein the first actual amount is nearly equal to the first listed amount; and a first closed fill height for the first fluent product in the first product space. The second container can have: a second product space having a second product space construction that is based, at least in part, on a second folding pattern that is substantially the same as the first folding pattern; a second external amount indicium that indicates a second listed amount of a second fluent product that is being offered for sale with the second container (the second fluent product may be similar to, or the same as, or different from the first fluent product), wherein the second listed amount is a particular percentage less than the first listed amount, and the particular percentage is greater than or equal to 0.1% and less than or equal to 70%; a second actual amount of the second fluent product, disposed in the second product space, wherein the second actual amount is nearly equal to the second listed amount; and a second closed fill height for the second fluent product in the second product space, wherein the second closed fill height is greater than or equal to the first closed fill height.
In a second set of embodiments of the present disclosure, in a line-up of flexible containers having similar constructions, one of the containers can hold relatively less fluent product at an unexpectedly high fill height. This line-up of flexible containers can comprise a first disposable self-supporting flexible container and a second disposable self-supporting flexible container. Any or all of the containers in the line-up may or may not be configured for retail sale. The first container can have: a first product space construction that is based, at least in part, on a first folding pattern; a first external amount indicium that indicates a first listed amount of a first fluent product that is being offered for sale with the first container; a first actual amount of the first fluent product, disposed in the first product space, wherein the first actual amount is nearly equal to the first listed amount; and a first closed fill height for the first fluent product in the first product space. The second container can have: a second product space having a second product space construction that is based, at least in part, on a second folding pattern that is substantially the same as the first folding pattern; a second external amount indicium that indicates a second listed amount of a second fluent product that is being offered for sale with the second container (the second fluent product may be similar to, or the same as, or different from the first fluent product), wherein the second listed amount is a particular percentage less than the first listed amount, and the particular percentage is greater than or equal to 0.1% and less than or equal to 70%; a second actual amount of the second fluent product, disposed in the second product space, wherein the second actual amount is nearly equal to the second listed amount; and a second closed fill height for the second fluent product in the second product space, wherein the second closed fill height is a particular calculated value that falls within certain mathematical expressions (explained herein) that represent an unexpectedly high fill height.
In a third set of embodiments of the present disclosure, in a line-up of flexible containers having similar external shapes, one of the containers can hold relatively less fluent product. This line-up of flexible containers can comprise a first disposable self-supporting flexible container and a second disposable self-supporting flexible container. Any or all of the containers in the line-up may or may not be configured for retail sale. The first container can have a first overall front profile and a first product space with a first total capacity. The second container can have a second disposable self-supporting flexible container, having a second overall front profile that has substantially the same size and shape as the first overall front profile, and a second product space with a second total capacity that is a particular percentage less than the first total capacity; wherein the particular percentage is greater than or equal to 5% and less than or equal to 70%.
In a fourth set of embodiments of the present disclosure, in a line-up of flexible containers having similar external sizes, one of the containers can hold relatively less fluent product. This line-up of flexible containers can comprise a first disposable self-supporting flexible container and a second disposable self-supporting flexible container. Any or all of the containers in the line-up may or may not be configured for retail sale. The first container can have a first overall external displacement and a first product space with a first total capacity. The second container can have a second disposable self-supporting flexible container, having a second overall external displacement, and a second product space with a second total capacity that is a particular percentage less than the first total capacity; wherein the particular percentage is greater than or equal to 5% and less than or equal to 70%; and wherein the second overall external displacement is greater than or equal to the first overall external displacement.
Each of these line-ups of flexible containers offers a number of advantages. A product size can be changed with less expense, because processing equipment for a flexible container can be designed to change from one size to another, without the need to purchase new equipment. A product size can be changed in less time, because processing equipment for a flexible container can be changed over in hours or minutes (or even on the fly) rather than waiting for new equipment. A product size can be changed with less coordination, because flexible containers can be designed to have internal capacities that are different, but external dimensions that are similar (or the same). So, when using flexible containers of the present disclosure, a manufacturer can easily change such containers from one product size to another product size.

Even though the containers of the present disclosure are made from flexible material, they can be configured with sufficient structural integrity, such that they can receive, contain, and dispense fluent product(s), as intended, without failure. Also, these containers can be configured with sufficient structural integrity, such that they can withstand external forces and environmental conditions from handling, without failure. Further, these containers can be configured with structures that allow them to be displayed for sale and put into use, as intended, without failure.
As used herein, the term “about” modifies a particular value, by referring to a range equal to the particular value, plus or minus twenty percent (+/−20%). For any of the embodiments of flexible containers, disclosed herein, any disclosure of a particular value, can, in various alternate embodiments, also be understood as a disclosure of a range equal to about that particular value (i.e. +/−20%).
As used herein, the term “actual amount” refers to a measured amount of the fluent product(s) present in a product space of a container when the container is configured for retail sale.
As used herein, the term “ambient conditions” refers to a temperature of 19-21 degrees Celsius and a relative humidity of 45-55%.
As used herein, the term “approximately” modifies a particular value, by referring to a range equal to the particular value, plus or minus fifteen percent (+/−15%). For any of the embodiments of flexible containers, disclosed herein, any disclosure of a particular value, can, in various alternate embodiments, also be understood as a disclosure of a range equal to approximately that particular value (i.e. +/−15%).
As used herein, the term “atmospheric pressure” refers to an absolute pressure of 1 atmosphere.
As used herein, when referring to a sheet of material, the term “basis weight” refers to a measure of mass per area, in units of grams per square meter (gsm). For any of the embodiments of flexible containers, disclosed herein, in various embodiments, any of the flexible materials can be configured to have a basis weight of 10-1000 gsm, or any integer value for gsm from 10-1000, or within any range formed by any of these values, such as 20-800 gsm, 30-600 gsm, 40-400 gsm, or 50-200, etc.
As used herein, when referring to a flexible container, the term “bottom” refers to the portion of the container that is located in the lowermost 30% of the overall height of the container, that is, from 0-30% of the overall height of the container. As used herein, the term bottom can be further limited by modifying the term bottom with a particular percentage value, which is less than 30%. For any of the embodiments of flexible containers, disclosed herein, a reference to the bottom of the container can, in various alternate embodiments, refer to the bottom 25% (i.e. from 0-25% of the overall height), the bottom 20% (i.e. from 0-20% of the overall height), the bottom 15% (i.e. from 0-15% of the overall height), the bottom 10% (i.e. from 0-10% of the overall height), or the bottom 5% (i.e. from 0-5% of the overall height), or any integer value for percentage between 0% and 30%.
As used herein, the term “branding” refers to a visual element intended to distinguish a product from other products. Examples of branding include one of more of any of the following: trademarks, trade dress, logos, icons, and the like. For any of the embodiments of flexible containers, disclosed herein, in various embodiments, any surface of the flexible container can include one or more brandings of any size, shape, or configuration, disclosed herein or known in the art, in any combination.
As used herein, the term “character” refers to a visual element intended to convey information. Examples of characters include one or more of any of the following: letters, numbers, symbols, and the like. For any of the embodiments of flexible containers, disclosed herein, in various embodiments, any surface of the flexible container can include one or more characters of any size, shape, or configuration, disclosed herein or known in the art, in any combination.
As used herein, the term “closed” refers to a state of a product space, wherein fluent products within the product space are prevented from escaping the product space (e.g. by one or more materials that form a barrier), but the product space is not necessarily hermetically sealed. For example, a closed container can include a vent, which allows a head space in the container to be in fluid communication with air in the environment outside of the container.
As used herein, the term “closed fill height” refers to a distance that is measured when the container is configured for retail sale and while the container is standing upright on a horizontal support surface, the distance measured vertically from the upper side of the support surface to a fill line in a product space of the container. If a container does not have a standing upright orientation but does have a hanging orientation, then the term closed fill height refers to a distance that is measured when the container is configured for retail sale and while the container is hanging down from a support, the distance measured vertically from the lowest point on the container to a fill line in a product space of the container. If a container does not have a standing upright orientation or a hanging orientation, then the term closed fill height does not apply to the container.
As used herein, the term “deflation feature” refers to one or more structural features provided with a flexible container for use in deflating some or all of the expanded structural support volume(s) of the flexible container, by allowing expansion material(s) inside of the structural support volume to escape into the environment, so that the structural support volume is no longer expanded. A deflation feature can be used when the flexible container is ready to be disposed of (i.e. as waste, compost, and/or recyclable material). Any of the flexible containers disclosed herein can be configured with any number of any kind of deflation feature, configured in any way disclosed herein or known in the art.
One kind of deflation feature is a cutting device, which is a rigid element that includes a point or edge configured to cut and/or pierce through flexible material(s) that form at least part of a structural support volume. As an example, a cutting device can be included with a flexible container by attaching the device to any portion of the outside (e.g. top, middle, side, bottom, etc.) of the container with adhesive, or under a label, or any other way known in the art, for externally attaching rigid elements to a container. As another example, a cutting device can be included with a flexible container by including the device with other packaging material, such as attached to an outer carton, inside of an overwrap layer, in between containers provided together, etc. As still another example, a cutting device can be included with a flexible container by including the device inside of any portion of the container, such as in a product space, in a structural support volume, in a mixing chamber, in a dedicated space for the device, in a base structure, or any other way known in the art, for internally including rigid elements within a container. As yet another example, a cutting device can be included with a flexible container, by making the cutting device integral with or detachable from another rigid element that is part of the container, such as a rigid base structure, cap, dispenser, fitment, connecting element, reinforcing element, or any other rigid element for containers disclosed herein or known in the art. A cutting device can be configured to be any convenient size and any workable shape and can be used manually or through use of a tool. In addition to rigid elements, flexible materials that can be turned into a rigid cutting device through rolling up or folding flexible materials are also envisioned.
Another kind of deflation feature is an exit channel, which can be configured to be opened in material(s) that border or define at least a portion of the fillable space of a structural support volume. An exit channel can be an existing connection (e.g. seam, seal, or joint) in the container, which is configured to fail (e.g. separate and at least partially open) when exposed to opening forces. An exit channel can also be formed with one or more points, lines, and/or areas of weakness (e.g. thinned, scored, perforated, frangible seal, etc.), which are configured to fail or to otherwise be breached, when exposed to opening forces. An exit channel can be protected by another material, such as an adhesive label, to ensure the exit channel remains closed until the user wishes to deflate. An exit channel can further be formed by configuring the container with one or more tear initiation sites (such as a notch in an edge, a pull-tab, etc.) such that a tear propagating from the site(s) can open the flexible material. An exit channel can be configured to be any convenient size and any workable shape and can be opened manually (by grasping and pulling, by poking with a finger or fingernail, or any other way) or through use of a tool or by overpressurizing a structural support volume (through application of compressive force or controlled environmental conditions) such that the structural support volume fails when its expansion material(s) burst out.
Still another kind of deflation feature is a valve, connected to the fillable space of a structural support volume, wherein the valve can be opened to the container's environment. Embodiments of the present disclosure can use as a deflation feature, any and all embodiments of valves (including materials, structures, and/or features for valves, as well as any and all methods of making and/or using such valves), as disclosed in the following patent documents: U.S. nonprovisional patent application Ser. No. 13/379,655 filed Jun. 21, 2010, entitled “Collapsible Bottle, Method Of Manufacturing a Blank For Such Bottle and Beverage-Filled Bottle Dispensing System” in the name of Reidl, published as US2012/0097634; U.S. nonprovisional patent application Ser. No. 10/246893 filed Sep. 19, 2002, entitled “Bubble-Seal Apparatus for Easily Opening a Sealed Package” in the name of Perell, et al., published as 20040057638; and U.S. Pat. No. 7,585,528 filed Dec. 16, 2002, entitled
“Package having an inflated frame” in the name of Ferri, et al., granted on Sep. 8, 2009; each of which is hereby incorporated by reference.
As used herein, the term “directly connected” refers to a configuration wherein elements are attached to each other without any intermediate elements therebetween, except for any means of attachment (e.g. adhesive).
As used herein, when referring to a flexible container, the term “dispenser” refers to a structure configured to dispense fluent product(s) from a product space and/or from a mixing volume to the environment outside of the container. For any of the flexible containers disclosed herein, any dispenser can be configured in any way disclosed herein or known in the art, including any suitable size, shape, and flow rate. For example, a dispenser can be a push-pull type dispenser, a dispenser with a flip-top cap, a dispenser with a screw-on cap, a rotatable type dispenser, dispenser with a cap, a pump type dispenser, a pump spray type dispenser, a trigger spray type dispenser, a straw dispenser, a flip up straw dispenser, a straw dispenser with bite valve, a dosing dispenser, etc. A dispenser can be a parallel dispenser, providing multiple flow channels in fluid communication with multiple product spaces, wherein those flow channels remain separate until the point of dispensing, thus allowing fluent products from multiple product spaces to be dispensed as separate fluent products, dispensed together at the same time. A dispenser can be a mixing dispenser, providing one or more flow channels in fluid communication with multiple product spaces, with multiple flow channels combined before the point of dispensing, thus allowing fluent products from multiple product spaces to be dispensed as the fluent products mixed together. As another example, a dispenser can be formed by a frangible opening. As further examples, a dispenser can utilize one or more valves and/or dispensing mechanisms disclosed in the art, such as those disclosed in: published US patent application 2003/0096068, entitled “One-way valve for inflatable package”; U.S. Pat. No. 4,988,016 entitled “Self-sealing container”; and U.S. Pat. No. 7,207,717, entitled “Package having a fluid actuated closure”; each of which is hereby incorporated by reference. Still further, any of the dispensers disclosed herein, may be incorporated into a flexible container either directly, or in combination with one or more other materials or structures (such as a fitment), or in any way known in the art. In some alternate embodiments, dispensers disclosed herein can be configured for both dispensing and filling, to allow filling of product space(s) through one or more dispensers. In other alternate embodiments, a product space can include one or more filling structure(s) (e.g. for adding water to a mixing volume) in addition to or instead of one or more dispenser(s). Any location for a dispenser, disclosed herein can alternatively be used as a location for a filling structure. In some embodiments, a product space can include one or more filling structures in addition to any dispenser(s). And, any location for a dispenser, disclosed herein can alternatively be used as a location for an opening, through which product can be filled and/or dispensed, wherein the opening may be reclosable or non-reclosable, and can be configured in any way known in the art of packaging. For example, an opening can be: a line of weakness, which can be torn open; a zipper seal, which can be pulled open and pressed closed (e.g. a press seal), or opened and closed with a slider; openings with adhesive-based closures; openings with cohesive-based closures; openings with closures having fasteners (e.g. snaps, tin tie, etc.), openings with closures having micro-sized fasteners (e.g. with opposing arrays of interlocking fastening elements, such as hook, loops, and/or other mating elements, etc.), and any other kind of opening for packages or containers, with or without a closure, known in the art.
As used herein, when referring to a flexible container, the term “disposable” refers to a container which, after dispensing a product to an end user, is not configured to be refilled with an additional amount of the product, but is configured to be disposed of (i.e. as waste, compost, and/or recyclable material). Part, parts, or all of any of the embodiments of flexible containers, disclosed herein, can be configured to be disposable.
As used herein, when referring to a flexible container, the term “durable” refers to a container that is reusable more than non-durable containers.
As used herein, when referring to a flexible container, the term “effective base contact area” refers to a particular area defined by a portion of the bottom of the container, when the container is configured for retail sale and is standing upright and its bottom is resting on a horizontal support surface, determined as described below. The effective base contact area lies in a plane defined by the horizontal support surface. The effective base contact area is a continuous area bounded on all sides by an outer periphery.
The outer periphery is formed from an actual contact area and from a series of projected areas from defined cross-sections taken at the bottom of the container. The actual contact area is the one or more portions of the bottom of the container that contact the horizontal support surface, when the effective base contact area is defined. The effective base contact area includes all of the actual contact area. However, in some embodiments, the effective base contact area may extend beyond the actual contact area.
The series of projected area are formed from five horizontal cross-sections, taken at the bottom of the flexible container. These cross-sections are taken at 1%, 2%, 3%, 4%, and 5% of the overall height. The outer extent of each of these cross-sections is projected vertically downward onto the horizontal support surface to form five (overlapping) projected areas, which, together with the actual contact area, form a single combined area. This is not a summing up of the values for these areas, but is the formation of a single combined area that includes all of these (projected and actual) areas, overlapping each other, wherein any overlapping portion makes only one contribution to the single combined area.
The outer periphery of the effective base contact area is formed as described below. In the following description, the terms convex, protruding, concave, and recessed are understood from the perspective of points outside of and around the combined area. The outer periphery is formed by a combination of the outer extent of the combined area and any chords, which are straight line segments constructed as described below.
For each continuous portion of the combined area that has an outer perimeter with a shape that is concave or recessed, a chord is constructed across that portion. This chord is the shortest straight line segment that can be drawn tangent to the combined area on both sides of the concave/recessed portion.
For a combined area that is discontinuous (formed by two or more separate portions), one or more chords are constructed around the outer perimeter of the combined area, across the one or more discontinuities (open spaces disposed between the portions). These chords are straight line segments drawn tangent to the outermost separate portions of the combined area. These chords are drawn to create the largest possible effective base contact area.
Thus, the outer periphery is formed by a combination of the outer extent of the combined area and any chords, constructed as described above, which all together enclose the effective base area. Any chords that are bounded by the combined area and/or one or more other chords, are not part of the outer periphery and should be ignored.
Any of the embodiments of flexible containers, disclosed herein, can be configured to have an effective base contact area from 1 to 50,000 square centimeters (cm2), or any integer value for cm2 between 1 and 50,000 cm2, or within any range formed by any of the preceding values, such as: from 2 to 25,000 cm2, 3 to 10,000 cm2, 4 to 5,000 cm2, 5 to 2,500 cm2, from 10 to 1,000 cm2, from 20 to 500 cm2, from 30 to 300 cm2, from 40 to 200 cm2, or from 50 to 100 cm2, etc.
In a line-up of flexible containers, according to any of the embodiments disclosed herein, both or all of the flexible containers in the line-up can have an effective base contact area that is about, approximately, substantially, or nearly the same in size and/or shape.
As used herein, when referring to a flexible container, the term “expanded” refers to the state of one or more flexible materials that are configured to be formed into a structural support volume, after the structural support volume is made rigid by one or more expansion materials. An expanded structural support volume has an overall width that is significantly greater than the combined thickness of its one or more flexible materials, before the structural support volume is filled with the one or more expansion materials. Examples of expansion materials include liquids (e.g. water), gases (e.g. compressed air), fluent products, foams (that can expand after being added into a structural support volume), co-reactive materials (that produce gas), or phase change materials (that can be added in solid or liquid form, but which turn into a gas; for example, liquid nitrogen or dry ice), or other suitable materials known in the art, or combinations of any of these (e.g. fluent product and liquid nitrogen). In various embodiments, expansion materials can be added at atmospheric pressure, or added under pressure greater than atmospheric pressure, or added to provide a material change that will increase pressure to something above atmospheric pressure. For any of the embodiments of flexible containers, disclosed herein, its one or more flexible materials can be expanded at various points in time, with respect to its manufacture, sale, and use, including, for example: before or after its product space(s) are filled with fluent product(s), before or after the flexible container is shipped to a seller, and before or after the flexible container is purchased by an end user.
As used herein, when referring to a container for retail sale of one or more fluent products, the term “external amount indicium” refers to an indicium that is joined to the container, that is visible from outside of the container, and that indicates a listed amount of fluent product that is being offered for sale with the container. The indicium can be any kind of indicium described herein or known in the art. In various embodiments, the indicium can be a particular value in various units of measurement (e g milliliters and/or fluid ounces for a fluent product that is a liquid; grams and/or ounces of weight for a fluent product that is a pourable solid). In various embodiments, the indicium can be for a particular product size that is associated with a particular amount of fluent product being offered for sale. The indicium can be provided on a label or as printing or in any other form described herein or known in the art. The indicium can be joined to an outside of the container or joined to an inside of the container (and visible through a transparent portion of the container), or on secondary packaging connected to the container. Alternatively, instead of being joined to the container, the indicium can be presented as part of a merchandising display for the container or can be communicated via advertising materials. An external amount indicium is typically applied to a container by the manufacturer of the product or by a retailer of the product.
Although a manufacturer may earnestly endeavor to make products that are properly filled and accurately labeled, there may be some limited instances, in which a container may contain an actual amount of fluent product that is not exactly equal to the listed amount of fluent product indicated by its external amount indicium. As a first example, a manufacturer may intentionally overfill containers, in an attempt to make up for projected losses of fluent product (from evaporation) during their shelf life. As a second example, a manufacturer may experience variability in the filling of containers, resulting in a few containers having actual amounts of fluent product that vary somewhat from a targeted amount of fill. As a third example, a retailer may unintentionally sell a product that has passed its expected shelf life, and has experienced a larger than projected loss of fluent product (from evaporation). Despite these limited instances, a container offered for retail sale typically contains an actual amount of fluent product that is nearly equal to the listed amount of fluent product indicated by its external amount indicium.
As used herein, when referring to a product space of a flexible container, the term “filled” refers to the state of the product space in the container (which is fully manufactured) after the filling of its product space(s) with fluent product(s) is complete and the container is fully closed and/or sealed, wherein the container has not been opened or unsealed, and wherein the fluent product(s) in the container have not been put into its/their intended end use.
A filled product space may or may not include an allowance for headspace, depending on the kind of fluent product(s) being contained, and the requirements for containing the fluent product(s). As an example, a manufacturer can label a flexible container with an external amount indicium that indicates a listed amount of a fluent product that is being offered for sale with the container, can add to the product space of the container an actual amount of the fluent product that is nearly equal to the listed amount (but still includes a headspace that is designed for that fluent product in that product space), and can close the container so the container is configured for retail sale; that container is considered filled. As used herein, the term filled can be modified by using the term filled with a particular percentage value.
As used herein, the term “flat” refers to a surface that is without significant projections or depressions.
As used herein, the term “flexible container” refers to a container with a product space, wherein one or more flexible materials form 50-100% of the overall surface area of the one or more materials that define the three-dimensional space of the product space.

As used herein, when referring to a flexible container, the term “non-fluent product” refers to materials, products, and/or articles that are not liquids, pourable solids, or combinations or liquids and pourable solids. Any of the flexible containers disclosed herein can be configured for packaging one or more of any non-fluent product disclosed herein, or known in the art, in any combination. When used for non-fluent products, flexible containers, as disclosed herein, can provide benefits associated with partly or fully supporting and/or enclosing the non-fluent product with primary and/or secondary packaging that includes one or more structural support volumes, one or more structural support members, and/or one or more structural support frames; for example, so the non-fluent product can be supported and/or enclosed by packaging that is self-supporting and/or standing upright, as will be understood by one skilled in the art.
As used herein, when referring to a flexible container, the term “nonstructural panel” refers to a layer of one or more adjacent sheets of flexible material, the layer having an outermost major surface that faces outward, toward the environment outside of the flexible container, and an innermost major surface that faces inward, toward one or more product spaces disposed within the flexible container; a nonstructural panel is configured such that, the layer, does not independently provide substantial support in making the container self-supporting and/or standing upright.
As used herein, the term “overall external displacement” refers to a total volume of a flexible container that is configured for retail sale, when measured according to the following test method for displacement. The test method for displacement is used on one flexible container at a time. Before the testing begins, all secondary packaging is removed from the flexible container; however, the flexible container is neither opened nor unsealed before the testing. The test method for displacement is performed under ambient conditions and at atmospheric pressure. The flexible container is fully submerged in a rigid open container of distilled water that has a temperature of 19-21 degrees Celsius. While the flexible container is submerged, the size and shape of the flexible container must not be artificially distorted by any part of the testing equipment. Before the displacement is measured, any air pockets trapped beneath the flexible container must be removed; also any large bubbles (having diameter greater than 1 centimeter) in the water must be removed. When the displacement is measured, the flexible container is fully submerged, in a standing orientation on a bottom of the rigid open container, and submerged to a depth such that an uppermost portion of the flexible container is 1-5 centimeters beneath the surface of the water. The overall external displacement of the flexible container is measured by determining how much water is displaced by the flexible container when the flexible container is fully submerged, as described above.
As used herein, the term “open fill height” refers to a distance that is measured (as described below) for a container that was configured for retail sale, immediately after the product space is opened and (if applicable) unsealed for the first time, but before any of the fluent product in the product space has been mixed, dispensed, and/or used, and before anything has been added into any part of the container. The open fill height is measured while the container is standing upright on a horizontal support surface, and is measured vertically from the upper side of the support surface to a fill line in a product space of the container. If a container does not have a standing upright orientation but does have a hanging orientation, then the open fill height is measured while the container is hanging down from a support, and is measured vertically from the lowest point on the container to a fill line in a product space of the container.
As used herein, the term “overall front profile” refers to a full-scale size and shape of an outline of a flexible container (excluding any secondary packaging and any removable portions, such as a cap, which are removed from the container before the overall front profile is determined), when the container is configured for retail sale, wherein the overall front profile is determined when a front of the container is directly viewed straight-on toward the container's center, determined as described below. If the flexible container is a stand up container, then the overall front profile is determined while the container is standing up.

In a line-up of flexible containers, according to any of the embodiments described herein, a first flexible container can have a first predetermined volume of a first expansion material sealed inside, while a second disposable flexible container can have a second predetermined volume of a second expansion material (which can be similar to, the same as, or different from the first expansion material) sealed inside, wherein the second predetermined volume is greater than the first predetermined volume. For example, the first flexible container can have the first predetermined volume of the first expansion material sealed inside one or more first structural support volumes, such as structural support volumes that form the first structural support frame for the first container, while the second disposable flexible container can have the second predetermined volume of the second expansion material sealed inside one or more second structural support volumes, such as structural support volumes that form a second structural support frame for the second container. In various embodiments, the second predetermined volume can be 10-1000% more than the first predetermined volume, or any integer value for percentage from 10-1000%, or within any range formed by any of these values, such as 20-500%, 30-100%, etc.
In a line-up of flexible containers, according to any of the embodiments described herein, a first flexible container can have a first expansion material sealed inside at a first internal expansion pressure, while a second disposable flexible container can have a second expansion material sealed inside at a second internal expansion pressure, wherein the second internal expansion pressure is within 85% of the first internal pressure, or any integer value for percentage from 0-85%, or within any range formed by any of these values, such as 0-50%, 0-20%, etc.
A relatively different volume and/or pressure of expansion material(s) can be added to a structural support volume of a structural support frame of a flexible container in various ways, such as changing a flow rate when adding expansion material(s), and/or changing a time for adding expansion material(s), and/or changing a pressure at which expansion material(s) are added, and/or using an additional/alternate nozzle/dispenser for adding expansion material(s), and/or adding different expansion material(s) that expand at different rates or to different volumes, and/or changing an ability of expansion material(s) to escape before sealing the structural support frame, and/or sealing the structural support frame at a different sealing time after adding expansion materials, and/or sealing the structural support frame at a different sealing rate after adding expansion materials, and/or changing a size and/or shape of one or more structural support volumes in the structural support frame, etc. To make a flexible container that contains a particular predetermined volume and/or pressure of expansion material(s), one skilled in the art can empirically determine a target volume and/or pressure for the expansion material(s), in expanded form, within a flexible container, and then vary one or more of the conditions mentioned above, in the process of making the flexible container, to obtain the target volume and/or pressure.

The folding pattern 1920 includes a first set of seals 1929-1, a second set of seals 1929-2, and a third set of seals 1929-3, which are illustrated in
The first set of seals 1929-1 includes: the pair of mirrored trapezoidal shapes that are offset from the edges of the blank 1900-b, on the left and right sides; two pairs of linear segments that extend along central parts of the top and bottom edges of the blank 1900-b, on its left and right sides; and one linear segment that extends along the right side edge of the blank 1900-b. The first set of seals 1929-1 seals through both the first shaped cutout 1929-b1 and the second shaped cutout 1929-b2.
The sealing of the mirrored trapezoidal shapes from the first set of seals 1929-1 forms nonstructural panels for a product space of the flexible container being made from the blank 1900-b. As a result, for the flexible container being made from the blank 1900-b, the product space construction is based, at least in part on the sealing pattern 1920. In particular, for the flexible container being made from the blank 1900-b, substantially all of the product space construction is based on the first set of seals 1929-1 in the sealing pattern 1920. In various embodiments, all of a product space construction can be based on a particular sealing pattern.
The sealing of the mirrored trapezoidal shapes from the first set of seals 1929-1 also forms inner portions of the structural support frame in the flexible container being made from the blank 1900-b. The sealing of the linear segments from the first set of seals 1929-1 forms outer portions of the structural support frame for the flexible container being made from the blank 1900-b.
After the blank 1900-b is sealed along the dashed lines of the first set of seals 1929-1, the blank 1900-b is folded according to the folding pattern 1940. The folding pattern 1940 includes a full fold at the fold line 1941, although in various embodiments, a folding line can include partial and/or full folds along any number of folding lines. The fold line 1941 extends continuously from the top edge of the blank 1900-b to the bottom edge of the blank 1900-b, although in various embodiments a fold line may be discontinuous or may extend over only part of a blank 1900-b.
The blank 1900-b is folded at the fold line 1941 so that the portions of the first shaped cutout 1929-b1 and the second shaped cutout 1929-b2 on the right side fully overlay and align with the portions of the first shaped cutout 1929-b1 and the second shaped cutout 1929-b2 on the left side. The folding of the blank 1900-b along the fold line 1941 further forms a top, a bottom, and sides of the flexible container being made from the blank 1900-b, wherein the narrow, open edge opposite the fold line 1941 is the partially formed top, the wide, folded edge adjacent the fold line 1941 is the partially formed bottom, and the angled, open, top and bottom edges are the partially formed sides. As a result, for the flexible container being made from the blank 1900-b, the container construction is based, at least in part on the folding pattern 1940. In particular, for the flexible container being made from the blank 1900-b, the container construction is based on the fold line 1941 of the folding pattern 1940. In various embodiments, substantially all or all of a container construction can be based on a particular folding pattern.
The folding of the blank 1900-b along the fold line 1941 also further forms the product space of the flexible container by bringing the nonstructural panels into positions that will be on a front and a back of the flexible container being made from the blank 1900-b. As a result, for the flexible container being made from the blank 1900-b, the product space construction is based, at least in part on the folding pattern 1940. In particular, for the flexible container being made from the blank 1900-b, the product space construction is based on the fold line 1941 of the folding pattern 1940. In various embodiments, substantially all or all of a product space construction can be based on a particular folding pattern.
After the blank 1900-b is folded according to the folding pattern 1940 and while the blank 1900-b is maintained in this folded state, the blank 1900-b is sealed with continuous seals along the dashed lines of the second set of seals 1929-2. The second set of seals 1929-2 is represented by the dashed lines having an intermediate dash length in
The second set of seals 1929-2 includes: one pair of linear segments that extend along significant portions of the top and bottom edges of the blank 1900-b, on its left side, including portions that extend next to and along portions of the first set of seals 1929-1. Since the second set of seals 1929-2 is made while the blank 1900-b is folded, the second set of seals 1929-2 seals through the left side of the second shaped cutout 1929-b2, the left side and the (original) right side of the first shaped cutout 1929-b1, and the (original) right side of the second shaped cutout 1929-b2. The sealing of the linear segments from the second set of seals 1929-2 forms outer portions of the structural support frame for the flexible container being made from the blank 1900-b. The sealing of the linear segments from the second set of seals 1929-2 also forms an outer extent of the product space of the flexible container being made from the blank 1900-b.
Before the structural support frame is fully sealed, one or more expansion materials can be added to the partially formed structural support frame, as described herein. And, before the product space is fully closed and/or sealed, one or more fluent products can be added to the partially formed product space, as described herein.
After the blank 1900-b is sealed along the dashed lines of the second set of seals 1929-2 and while the blank 1900-b remains in the folded and partially sealed state, the blank 1900-b is sealed with continuous seals along the dashed lines of the third set of seals 1929-3. The third set of seals 1929-3 is represented by the dashed lines having a shortest dash length in
The third set of seals 1929-2 includes: one pair of linear segments that extend in parallel from the left side edge of the blank 1900-b, inward to the trapezoidal shape; a first three sided shape, having a first side extending from the upper parallel segment, along an upper portion of the left side edge of the blank 1900-b, a second side extending along an outer portion of the top edge of the blank 1900-b, and a third side extending from the top edge of the blank 1900-b back to the upper parallel segment; a second three sided shape, having a first side extending from the lower parallel segment, along a lower portion of the left side edge of the blank 1900-b, a second side extending along an outer portion of the bottom edge of the blank 1900-b, and a third side extending from the bottom edge of the blank 1900-b back to the lower parallel segment; and, a pair of linear segments that extend next to and along outer portions of the trapezoidal shape from the first set of seals 192-1.
Since the third set of seals 1929-3 is made while the blank 1900-b is folded, the third set of seals 1929-3 seals through the left side of the second shaped cutout 1929-b2, the left side and the (original) right side of the first shaped cutout 1929-b1, and the (original) right side of the second shaped cutout 1929-b2. The sealing of the parallel linear segments from the third set of seals 1929-3 forms a product dispensing path in the flexible container being made from the blank 1900-b; the product dispensing path can be closed and/or sealed with any kind of suitable closure, seal, or dispenser disclosed herein or known in the art. The sealing of the other linear segments from the third set of seals 1929-3 forms portions of the top of the flexible container being made from the blank 1900-b, and also fully seals the structural support frame of the flexible container being made from the blank 1900-b.
In a line-up of flexible containers, according to any of the embodiments disclosed herein, both or all of the flexible containers in the line-up can include one or more product spaces, each product space having a product space construction, and any of the product space constructions can be partly, substantially, or fully based on part, parts, or all of one or more common folding patterns and/or can be partly, substantially, or fully based on part, parts, or all of one or more common sealing patterns.

In any embodiment of the line-up of
The flexible containers of
In a first set of embodiments of the present disclosure, a line-up of flexible containers having similar constructions can hold different amounts of fluent product at similar fill heights.

In a second set of embodiments of the present disclosure, in a line-up of flexible containers having similar constructions, one of the containers can hold relatively less fluent product at an unexpectedly high fill height. This line-up of flexible containers can comprise a first disposable self-supporting flexible container and a second disposable self-supporting flexible container. Any or all of the containers in the line-up may or may not be configured for retail sale. The first container can have: a first product space construction that is based, at least in part, on a first folding pattern; a first external amount indicium that indicates a first listed amount of a first fluent product that is being offered for sale with the first container; a first actual amount of the first fluent product, disposed in the first product space, wherein the first actual amount is nearly equal to the first listed amount; and a first closed fill height for the first fluent product in the first product space. The second container can have: a second product space having a second product space construction that is based, at least in part, on a second folding pattern that is substantially the same as the first folding pattern; a second external amount indicium that indicates a second listed amount of a second fluent product that is being offered for sale with the second container (the second fluent product may be similar to, or the same as, or different from the first fluent product), wherein the second listed amount is a particular percentage less than the first listed amount, and the particular percentage is greater than or equal to 0.1% and less than or equal to 70%; a second actual amount of the second fluent product, disposed in the second product space, wherein the second actual amount is nearly equal to the second listed amount; and a second closed fill height for the second fluent product in the second product space, wherein the second closed fill height is within a particular range of calculated values (explained herein) that represent an unexpectedly high fill height.
In one example of a line-up from this second set of embodiments, any embodiment of the flexible container 2000-a described herein can be used as the first container in the line-up (as described above) while any embodiment of the flexible container 2000-c described herein can be used as the second container in the line-up (as described above); these containers can also be used with any variation of this line-up described herein. In another example of a line-up from this second set of embodiments, any embodiment of the flexible container 2000-b described herein can be used as the first container in the line-up (as described above) while any embodiment of the flexible container 2000-a described herein can be used as the second container in the line-up (as described above); these containers can also be used with any variation of this line-up described herein.
In a line-up of flexible containers, according to any of the embodiments in the first or second set of embodiments, described above, the particular percentage can be greater than or equal to 1% and less than or equal to 70%, or any integer value for percentage between 1% and 70%, or any range formed by any of these integer values, such as: greater than or equal to 1% and less than or equal to 60%, greater than or equal to 2% and less than or equal to 50%, greater than or equal to 3% and less than or equal to 40%, etc. Also, in a line-up of flexible containers, according to any of the embodiments described herein, the second product space of the second container can have a second total capacity that is 1% to 70% less than a first total capacity of the first product space of the first container, or the second total capacity can be less than the first total capacity by any integer value for percentage between 1% and 70%, or by any range formed by any of these integer values, such as 5-70%, 10-60%, 15-50%, 20-40%, etc.
In a line-up of flexible containers, according to any of the embodiments in the first or second set of embodiments, described above, the first container and the second container can have various headspace pressures as described below.
In various embodiments, the first container can have a first product space that is sealed closed and has a first headspace at a first sealed closed headspace pressure, while the second container can have a second product space that is sealed closed and has a second headspace at a second sealed closed headspace pressure that is 0-20% of the first sealed closed headspace pressure, or any integer value for percentage from 0% to 20%, or within any range formed by any of these values, such as 0-10%. When the second sealed closed headspace pressure in the product space of the second container is about the same as the first sealed closed headspace pressure in the product space of the first container—despite the fact that the containers have similar constructions, and the second container has a lesser amount of fluent product—this can indicate that the product spaces of the containers are configured to not apply significant (positive or negative) forces on the fluent product that they contain, when sealed closed. These kinds of configurations can be accomplished by permanently increasing a total capacity of the first product space of the first flexible container and/or by permanently decreasing a total capacity of the second product space of the second flexible container, as described herein.
And, in various embodiments, a flexible container can have a product space that is sealed closed at a sealed closed headspace pressure that is 0-20% of atmospheric pressure, or any integer value for percentage from 0% to 20%, or within any range formed by any of these values, such as 0-10%. When a sealed closed headspace pressure in the product space of a container is about the same as atmospheric pressure, this can indicate that the product space of the container is configured to not apply significant (positive or negative) forces on the fluent product that it contains, when sealed closed. This kind of configuration can be accomplished by permanently setting a total capacity of a product space in the flexible container, as described herein.
Further, in various embodiments, a flexible container can have a product space that is sealed closed with fluent product at a sealed closed fill height, wherein the container is configured such that, when the product space is opened, the fluent product in the product space assumes an open fill height that is within 30% of the sealed closed fill height, or any integer value for percentage from 0% to 30%, or within any range formed by any of these values, such as 0-20% or 0-10%. Also, the open fill height can be within 0-6 centimeters of the sealed closed fill height, or any integer value for centimeters from 0 to 6, or within any range formed by any of these values, such as 0-4 centimeters or 0-2 centimeters. When an open fill height in the product space of a flexible container is similar to the sealed closed fill height in the product space of the container—despite the fact that the container is open, such that the product space is vented and can equalize with the pressure of the environment—this can indicate that the product space of the container is configured to not apply significant (positive or negative) forces on the fluent product that it contains, when sealed closed. This kind of configuration can be accomplished by permanently setting a total capacity of a product space in the flexible container, as described herein.
In a third set of embodiments of the present disclosure, in a line-up of flexible containers having similar external shapes, one of the containers can hold relatively less fluent product. This line-up of flexible containers can comprise a first disposable self-supporting flexible container and a second disposable self-supporting flexible container. Any or all of the containers in the line-up may or may not be configured for retail sale. The first container can have a first overall front profile and a first product space with a first total capacity. The second container can have a second disposable self-supporting flexible container, having a second overall front profile that has substantially the same size and shape as the first overall front profile, and a second product space with a second total capacity that is a particular percentage less than the first total capacity; wherein the particular percentage is greater than or equal to 5% and less than or equal to 70%.
In one example of a line-up from this third set of embodiments, any embodiment of the flexible container 2000-a described herein can be used as the first container in the line-up (as described above) while any embodiment of the flexible container 2000-c described herein can be used as the second container in the line-up (as described above); these containers can also be used with any variation of this line-up described herein. In another example of a line-up from this third set of embodiments, any embodiment of the flexible container 2000-b described herein can be used as the first container in the line-up (as described above) while any embodiment of the flexible container 2000-a described herein can be used as the second container in the line-up (as described above); these containers can also be used with any variation of this line-up described herein.
In a fourth set of embodiments of the present disclosure, in a line-up of flexible containers having similar external sizes, one of the containers can hold relatively less fluent product. This line-up of flexible containers can comprise a first disposable self-supporting flexible container and a second disposable self-supporting flexible container. Any or all of the containers in the line-up may or may not be configured for retail sale. The first container can have a first overall external displacement and a first product space with a first total capacity. The second container can have a second disposable self-supporting flexible container, having a second overall external displacement, and a second product space with a second total capacity that is a particular percentage less than the first total capacity; wherein the particular percentage is greater than or equal to 5% and less than or equal to 70%; and wherein the second overall external displacement is greater than or equal to the first overall external displacement.
When the second overall external displacement of the second container is greater than or equal to the first overall external displacement of the first container—despite the fact that the second container has a lesser amount of fluent product—this can indicate that the containers are configured to have internal capacities that are different, but external dimensions that are similar (or the same). These kinds of configurations can be accomplished by changing product spaces within flexible containers, as described herein.
In a line-up of flexible containers, according to any of the embodiments in the fourth set of embodiments, described above, the particular percentage can be greater than or equal to 5% and less than or equal to 70%, or any integer value for percentage between 5% and 70%, or any range formed by any of these integer values, such as: greater than or equal to 10% and less than or equal to 60%, greater than or equal to 15% and less than or equal to 50%, greater than or equal to 20% and less than or equal to 40%, etc.
In a line-up of flexible containers, according to any of the embodiments in the fourth set of embodiments, described above, second overall external displacement can be: greater than and about equal to the first overall external displacement, greater than and approximately equal to the first overall external displacement, greater than and substantially equal to the first overall external displacement, and/or greater than and nearly equal to the first overall external displacement.
In one example of a line-up from this fourth set of embodiments, any embodiment of the flexible container 2000-a described herein can be used as the first container in the line-up (as described above) while any embodiment of the flexible container 2000-c described herein can be used as the second container in the line-up (as described above); these containers can also be used with any variation of this line-up described herein. In another example of a line-up from this fourth set of embodiments, any embodiment of the flexible container 2000-b described herein can be used as the first container in the line-up (as described above) while any embodiment of the flexible container 2000-a described herein can be used as the second container in the line-up (as described above); these containers can also be used with any variation of this line-up described herein.
The fill height 2171 is represented on the vertical axis of the chart 2170 as percentages from 120% to 0% where 100% represents a fill height of a fluent product in a product space that is 100% filled with the fluent product and 0% represents a fill height of a fluent product in a product space that is 0% filled with the fluent product. The fill volume 2172 is represented on the horizontal axis of the chart 2170 as percentages from 100% to 0% where 100% represents a reference amount of fluent product in a product space of a container that is 100% filled with a fluent product, 0% represents a product space in a container that is 0% filled with a fluent product, and percentages between 0% and 100% represent an amount of fluent product that is scaled to the reference amount.
The lines, curves, and areas on the chart 2170 represent how fill height 2171 can vary with fill volume 2172 for various types and configurations of product spaces in containers. For each particular product space, the fill height depends on the amount of fluent product in the product space—and the geometry and/or configuration of the product space. Part, parts, or all of a proportional line 2173 represent a container with a particular product space, wherein fill height 2171 varies in direct proportion to the fill volume 2172, as described and illustrated in connection with the conventional rigid containers of
Below the proportional line 2173 is a lower boundary curve 2174. Part, parts, or all of the lower boundary curve 2174 represent a container with a product space, wherein fill height 2171 at first drops very quickly as the fill volume 2172 initially decreases from 100% filled, then curves and drops quite slowly as the fill volume 2172 approaches 0% filled. The lower boundary curve 2174 represents a product space with a particular geometry and/or configuration, wherein the higher portions of the product space account for only a small portion of the filled volume, while the lower portions of the product space account for nearly all of the filled volume. As illustrated in the chart 2170, on the lower boundary curve 2174, with only a 10% reduction (from 100% to 90%) in fill volume 2172 the fill height 2171 drops quickly from 100% to about 50%, and then with a further 10% reduction (from 90% to 80%) in fill volume 2172 the fill height 2171 drops quickly again from about 50% to about 30%. Also as illustrated in
The lower boundary curve 2174 and the proportional line 2173, together enclose a lower area 2174-a on the chart 2170. The lower area 2174-a represents a range of product spaces, wherein as the fill volume 2172 initially decreases from 100% filled the fill height 2171 at first drops more quickly (than the proportional line 2173), then as the fill volume 2172 approaches 0% filled the fill height 2171 drops more slowly (than the proportional line 2173). The lower area 2174-a can include any number of curves and/or lines (not shown) that represent various relationships between fill height and fill volume within the range of product spaces, as will be understood by one skilled in the art. For filled product spaces that fall within the lower area 2174-a, more of the fluent product in the product space is found in the lower portions of the product space than in the upper portions of the product space, which is common in conventional containers for fluent products, and is especially common in conventional flexible containers for fluent products.
Above the proportional line 2173 is an upper boundary curve 2175. Part, parts, or all of the upper boundary curve 2175 represent a container with a product space, wherein as the fill volume 2172 initially decreases from 100% filled the fill height 2171 at first unexpectedly rises, then as the fill volume 2172 further decreases the fill height 2171 curves and drops quite slowly, then as the fill volume 2172 approaches 0% filled the fill height 2171 drops very quickly. The upper boundary curve 2175 represents a container with a particular geometry and configuration, wherein the product space is configured such that upper portions of the product space account for a large portion of the filled volume, while the lower portions of the product space account for a small portion of the filled volume. As illustrated in
In various embodiments, locations along the upper boundary curve 2175 can also represent product spaces for two or more flexible containers that form a line-up of flexible containers, as described herein. For example, in an exemplary line-up of containers, a first flexible container in the line-up can have a first product space wherein a first amount of fluent product corresponding with a first fill volume rises to a first fill height at a first point along the upper boundary curve 2175, while a second flexible container in the line-up can have a second product space wherein a second amount of fluent product (that differs from the first amount) corresponding with a second fill volume rises to a second fill height at a second point along the upper boundary curve 2175.
The upper boundary curve 2175 and the proportional line 2173, together enclose an upper area 2175-a on the chart 2170. The upper area 2175-a represents a range of containers, wherein fill height 2171 at first unexpectedly rises, or unexpectedly remains constant, or unexpectedly drops more slowly than the proportional line 2173 as the fill volume 2172 initially decreases from 100% filled, then drops and/or drops more quickly as the fill volume 2172 approaches 0% filled. The upper area 2175-a can include any number of curves and/or lines (not shown) that represent various relationships between fill height and fill volume within the range of product spaces, as will be understood by one skilled in the art. For filled product spaces that fall within the upper area 2175-a, more of the fluent product in the product space can be found in the upper portions of the product space than in the lower portions of the product space and the product space can be configured with fill heights that behave in unexpected ways for initially lesser amounts of fluent product in the product space, according to various embodiments disclosed herein. A product space configuration that falls anywhere within the upper area 2175-a can be used for any embodiment of flexible container described herein.
In various embodiments, locations within the upper boundary area 2175-a can also represent product spaces for two or more flexible containers that form a line-up of flexible containers, as described herein. For example, in an exemplary line-up of containers, a first flexible container in the line-up can have a first product space wherein a first amount of fluent product corresponding with a first fill volume rises to a first fill height at a first point within the upper boundary area 2175-a, while a second flexible container in the line-up can have a second product space wherein a second amount of fluent product (that differs from the first amount) corresponding with a second fill volume rises to a second fill height at a second point within the upper boundary area 2175-a.
The upper boundary area 2175-a also includes five modeled boundaries, including a first modeled boundary 2176-1, a second modeled boundary 2176-2, a third modeled boundary 2176-3, a fourth modeled boundary 2176-4, and a fifth modeled boundary 2176-5. Part, parts, or all of each of these modeled boundaries can represent a container with a particular geometry and/or configuration, wherein the modeled boundary represents various relationships between fill height and fill volume within a product space. Locations along each of these modeled boundaries can also represent product spaces for two or more flexible containers that form a line-up of flexible containers, as described herein.
In combination with the proportional line 2173, the five modeled boundaries 2176-1 through 2176-5 enclose five modeled areas, including a first modeled area 2176-1a, a second modeled area 2176-2a, a third modeled area 2176-3a, a fourth modeled area 2176-4a, and a fifth modeled area 2176-5a. Each of these modeled areas 2176-1a through 2176-5a represents a particular subset of the upper boundary area 2175-a. And, each of these modeled areas 2176-la through 2176-5a can include any number of curves and/or lines (not shown) that represent various relationships between fill height and fill volume within the ranges of the corresponding product spaces, as will be understood by one skilled in the art.
Since flexible containers for fluent products have product space configurations that most commonly fall within the lower area 2174-a, the proportional line 2173 can be considered a reasonable upper limit for the relationship between fill height and fill volume in a product space of a conventional flexible container (e.g. a pouch) for a fluent product. In a product space of a conventional flexible container for a fluent product, as fill volume initially decreases, a person skilled in the art would not expect fill height to drop more slowly than in direct proportion to the fill volume (i.e. more slowly than along the proportional line 2173). So, a person skilled in the art would not expect such a product space to have a relationship between fill height and fill volume that exists above the proportional line 2173. And, a person skilled in the art would also not expect two conventional flexible containers that have product spaces with product space constructions that are similar or the same to have a relationship between fill height and fill volume that exists above the proportional line 2173. This understanding can be used as a basis for a first mathematical expression, which is:
wherein:
FH2=second fill height, which is a fill height for a second particular amount of fluent product in a second product space of a second container,
FH1=first fill height, which is a fill height for a first particular amount of fluent product in a first product space of a first container, wherein the first product space has one or more defined similarities with respect to the second product space,
FV2=second fill volume, which is a second particular amount of fluent product in the second product space, wherein the second fill volume is less than a first fill volume,
FV1=first fill volume, which is a first particular amount of fluent product in the first product space.
The first mathematical expression states that the second fill height (FH2) is greater than: the first fill height (FH1) times the ratio of the second fill volume to the first fill volume (FV2/FV1). The ratio of the second fill volume to the first fill volume (FV2/FV1) represents a directly proportional relationship between the fill volumes. As a result, the first particular mathematical expression indicates that, in line-ups of flexible containers disclosed herein, the second fill height (FH2) is higher than the proportional line 2173 (i.e. higher than a directly proportional relationship to fill volume), when the second product space is filled with less fluent product. So, the first mathematical expression represents the lower limit for each of the five modeled areas 2176-1a through 2176-5a.
A first form of a second mathematical expression and a first form of a third mathematical expression together represent the five modeled boundaries 2176-1 through 2176-5, which form the upper limits for each of the five modeled areas 2176-1a through 2176-5a, respectively. The first form of the second mathematical expression represents the portions of the upper limits that extend from 100% filled to 30% filled. The first form of the third mathematical expression represents the portions of the upper limits that extend from 30% filled to 0% filled.
A first form of the second mathematical expression (for 100% to 30% filled) is:
and a first form of the third mathematical expression (for 30% to 0% filled) is:
wherein, for both the second and third mathematical expressions:
FH2=second fill height, which is a fill height for a second particular amount of fluent product in a second product space of a second container,
FH1=first fill height, which is a fill height for a first particular amount of fluent product in a first product space of a first container, wherein the first product space has one or more defined similarities with respect to the second product space,
FV2=second fill volume, which is a second particular amount of fluent product in the second product space, wherein the second fill volume is less than a first fill volume,
FV1=first fill volume, which is a first particular amount of fluent product in the first product space, SF=scaling factor (can range from 0.00 to 0.99, in any increment of 0.01).
The first form of the second mathematical expression states that (from 100% to 30% filled), along a modeled boundary, the second fill height (FH2) drops linearly, more slowly than the proportional line 2173. The first form of the third mathematical expression states that (from 30% to 0% filled), along a modeled boundary, the second fill height (FH2) drops linearly, more quickly than the proportional line 2173.
For the fifth modeled boundary 2176-5, the scaling factor (SF) equals 0.8. For the fourth modeled boundary 2176-4, the scaling factor (SF) equals 0.6. For the third modeled boundary 2176-3, the scaling factor (SF) equals 0.4. For the second modeled boundary 2176-2, the scaling factor (SF) equals 0.2. For the first modeled boundary 2176-1, the scaling factor (SF) equals 0.0. Table 1, below, shows exemplary values for the second fill height (FH2) for each of the five modeled boundaries 2176-1 through 2176-5, based on the scaling factors listed above.
The results in Table 1 are consistent with the modeled boundaries 2176-1 through 2176-5 illustrated on the chart 2170.
While the first forms of the second and third mathematical expressions define the modeled boundaries 2176-1 through 2176-5, second forms of these expressions are used to define the modeled areas 2176-1a through 2176-5a. The difference between the first forms and the second forms is that the equal signs (for use with the boundaries) are replaced by less than or equal to signs (for use with the areas), to indicate that within the modeled areas, the second fill height (FH2) is less than or equal to the modeled boundaries. So, the second form of the second mathematical expression (for 100% to 30% filled) is:
and the second form of the third mathematical expression (for 30% to 0% filled) is:
So, each of the five modeled areas 2176-1a through 2176-5a has a lower limit defined by the first mathematical expression and an upper limit defined by the second form of the second mathematical expression (for 100% to 30%) and by the second form of the third mathematical expression (30% to 0%), with a scaling factor (SF) of 0.0 for the first modeled area 2176-1a, 0.2 for the second modeled area 2176-2a, 0.4 for the third modeled area 2176-3a, 0.6 for the fourth modeled area 2176-4a, and 0.8 for the fifth modeled area 2176-5a.

The squeeze panel 2780-a includes a treated area 2780-ta, which is treated with one or more treatments that increase the rigidity of flexible materials, as described below. While the squeeze panel 2780-a has one treated area 2780-ta, a squeeze panel can have any number of treated areas. The treated area 2780-ta is an oval shaped portion of the squeeze panel 2780-a, however a treated area can have any convenient size and shape. The treated area 2780-ta is laterally centered on a middle portion of the squeeze panel 2780-a, however a treated area can be disposed on any part of a squeeze panel. A treated area may extend over part, parts, or all of a top, middle, or bottom portion of a squeeze panel, in any convenient arrangement. A treated area may or may not be centered on the squeeze panel, may or may not be laterally centered on the flexible container, and may or may not be adjacent to one or more portions of an outer periphery of the squeeze panel. The treated area 2780-ta is surrounded on all sides by an untreated portion of the squeeze panel 2780-a, however this particular relationship with surrounding elements is not required. The treated area 2780-ta is a continuous area, however, in various embodiments a treated area may be discontinuous (e.g. may include and/or be separated by one or more untreated portions) in any regular or irregular pattern. A treated area can cover 1-100% of an area of a squeeze panel, or any integer value for percentage from 1-100%, or within any range formed by any of these values, such as 1-90%, 1-80%, 1-70%, 1-60%, 1-50%, 1-40%, 1-30%, 1-20%, 1-10%, 10-100%, 20-100%, 30-100%, 40-100%, 50-100%, 60-100%, 70-100%, 80-100%, 90-100%, 10-90%, 20-80%, 30-70%, 40-60%, 45-55%, etc. Any embodiment of a flexible container disclosed herein can include a squeeze panel with the treated area 2780-ta as described and illustrated in connection with flexible container 2700-a of
Within the treated area 2780-ta, some or all of flexible material(s) of the squeeze panel 2780-a, can be treated with one or more of the treatments described below. The flexible materials can be chemically treated to increase their rigidity and/or to decrease their extensibility. The flexible materials can be coated to increase their rigidity and/or to decrease their extensibility. The flexible materials can also be treated with radiation to promote cross-linking between polymers within the materials (or coated thereon) for increasing rigidity and/or decreasing extensibility. The flexible materials can also be treated in any other way known in the art of flexible materials, for increasing rigidity and/or decreasing extensibility.
A treated area can be treated at various points in the process for making a flexible container. As examples, one or more treatments can be applied to flexible materials before they are received, after they are received but before they are converted, or even after they are converted. However, one or more treatments may be conveniently applied to flexible materials after their unwinding but before they are singulated, to more easily align treated area(s) with specific locations on flexible containers.
In the embodiment of
In various alternative embodiments, the squeeze panel 2780-b may include a treated area, so long as there is a difference in rigidity and/or extensibility that enables the squeeze panel 2780-b of the flexible container 2700-b to bulge out to a relatively greater extent than the squeeze panel 2780-a of the flexible container 2700-a of
In the embodiment of
In various alternative embodiments, the squeeze panel 2780-b may include a treated area with other configurations, so long as there is a difference in rigidity and/or extensibility that enables the squeeze panel 2780-c of the flexible container 2700-c to bulge out to a relatively lesser extent than the squeeze panel 2780-a of the flexible container 2700-a of
The squeeze panel 2880-a includes a treated area 2880-ta, which is treated with one or more treatments that increase the extensibility of flexible materials, as described below. The squeeze panel 2880-a has one treated area 2880-ta, which is an oval shaped continuous area that is laterally centered on a middle portion of the squeeze panel 2880-a, and surrounded on all sides by an untreated portion of the squeeze panel 2880-a, however this particular configuration is not required, and the treated area 2880-a can be configured in any manner disclosed herein for treated areas. Any embodiment of a flexible container disclosed herein can include a squeeze panel with the treated area 2880-ta as described and illustrated in connection with flexible container 2800-a of
Within the treated area 2880-ta, some or all of flexible material(s) of the squeeze panel 2880-a, can be treated with one or more of the treatments described below. The flexible materials can be mechanically treated to increase their extensibility; for example, the flexible materials can be embossed and/or incrementally stretched. Examples of incremental stretching include those found in U.S. Pat. No. 4,834,741 entitled “Diaper with Waist Band Elastic” by Sabee in the name of Tuff Spun Products, Inc.; in U.S. Pat. No. 5,143,679 entitled “Method for sequentially stretching zero strain stretch laminate web to impart elasticity thereto without rupturing the web” by Weber, et al. in the name of The Procter & Gamble Company; in U.S. Pat. No. 5,156,793 entitled “Method for incrementally stretching zero strain stretch laminate web in a non-uniform manner to impart a varying degree of elasticity thereto” by Buell, et al. in the name of The Procter & Gamble Company; U.S. Pat. No. 5,167,897 entitled “Method for incrementally stretching a zero strain stretch laminate web to impart elasticity thereto” by Weber, et al. in the name of The Procter & Gamble Company; each of which, is hereby incorporated by reference. The flexible materials can be thermally treated to increase their extensibility; for example, the flexible materials can be heated by conduction, convection, and/or radiation. The flexible materials can also be treated in any other way known in the art of flexible materials, for increasing extensibility and/or decreasing rigidity.
In the embodiment of
In various alternative embodiments, the squeeze panel 2880-b may include a treated area with other configurations, so long as there is a difference in extensibility and/or rigidity that enables the squeeze panel 2880-b of the flexible container 2800-b to bulge out to a relatively greater extent than the squeeze panel 2880-a of the flexible container 2800-a of
In the embodiment of
In various alternative embodiments, the squeeze panel 2880-c may include a treated area, so long as there is a difference in rigidity and/or extensibility that enables the squeeze panel 2880-c of the flexible container 2800-c to bulge out to a relatively lesser extent than the squeeze panel 2880-a of the flexible container 2800-a of
Overlapping folds and other take-ups can be applied at various points in the process for making a flexible container. As an example, one or more folds or take-ups may be conveniently applied to flexible materials along with other folding—to more easily form the folds in a web or sheet—and along with other sealing—to set the folds while sealing the flexible materials into a fixed arrangement.
Joining locations can be applied at various points in the process for making a flexible container. As an example, one or more joining locations or take-ins may be conveniently applied to flexible materials after other sealing—to set the joining locations when the flexible materials are sealed into a fixed arrangement.
A surface stiffening member can be created in various ways, such as by selectively sealing portions of overlaid flexible materials, such as the flexible materials that can make a front panel or a back panel of a flexible container. A surface stiffening member can be expanded in any of the ways that a structural support member can be expanded, as described herein. In a flexible container, one or more surface stiffening members can be in fluid communication with each other and/or with one or more structural support volumes. The fluid communication can be always open or selectively open (e.g. controlled by a minimum required expansion pressure, or by a frangible seal, which breaks when subjected to a particular pressure, or through a flexible valve, which opens when subjected to a particular pressure).
The first surface stiffening member 3285-1a is in selective fluid communication with the structural support frame 3240-a through a first valve 3284-1a; since the structural support volumes of the structural support frame 3240-a are expanded and the first valve 3284-1a is open, the first surface stiffening member 3285-1a is also expanded. Similarly, the fifth surface stiffening member 3285-5a is in selective fluid communication with the structural support frame 3240-a through a sixth valve 3284-6a; since the structural support volumes of the structural support frame 3240-a are expanded and the sixth valve 3284-6a is open, the fifth surface stiffening member 3285-5a is also expanded. The second surface stiffening member 3285-2a is in selective fluid communication with the first surface stiffening member 3285-1a through a second valve 3284-2a; although the first surface stiffening member 3285-1a is expanded, since the second valve 3284-2a is closed, the second surface stiffening member 3285-2a is not expanded. Similarly, the fourth surface stiffening member 3285-4a is in selective fluid communication with the fifth surface stiffening member 3285-5a through a fifth valve 3284-5a; although the fifth surface stiffening member 3285-5a is expanded, since the fifth valve 3284-5a is closed, the fourth surface stiffening member 3285-4a is not expanded. The third surface stiffening member 3285-3a is in selective fluid communication with the second surface stiffening member 3285-2a through a third valve 3284-3a and is in selective fluid communication with the fourth surface stiffening member 3285-4a through a fourth valve 3284-4a; since the second surface stiffening member 3285-2a and the fourth surface stiffening member 3285-4a are not expanded, and since the third valve 3284-3a and the fourth valve 3284-4a are closed, the third surface stiffening member 3285-3a is not expanded.
Together, the expanded surface stiffening members 3285-a1 and 3285-5a create tensions across top and bottom portions of the front panel 3280-a that form the overall side profile for the flexible container 3200-a. These tensions enable the front panel 3280-a of the flexible container 3200-a to bulge out to a relatively lesser extent than if the surface stiffening members 3285-a1 and 3285-5a on the front panel 3280-a were not expanded.
