The present disclosure relates in general to packaging for products, and more particularly to bags and pouches, such as stand-up pouches. The disclosure is especially concerned with structures and techniques for maintaining a bag or pouch in a wide-open configuration to facilitate a user's access to the contents held therein.
Flexible materials, such as polymers and flexible films, are often used to construct packages for products, such as bags and pouches. Such packages can be used to hold a variety of items, such as snack food including trail mix, chips, nuts, fruit pieces, and other foods. In some cases, as in the snack food example, the type of product contained in the package is meant for consumption by the user one piece or portion at a time. For example, the consumer may reach into the package to withdraw a portion of the snack food, put them in his or her mouth, and then reach into the package again to obtain another portion for consumption. This pattern repeats until the consumer is full and/or does not want to eat any more of the package contents.
In another example, such as when the package is a large “family” or “party size” package, it is common for a consumer to open the package containing the snack food and share the food with others. In this case, one person may reach into the package, withdraw one or more items for consumption, then pass the package on to the next person who may then do the same.
Embodiments of the invention described herein provide improved packages and methods for constructing packages that provide a mechanism for maintaining the package in an open configuration, such that the mouth or opening of the package does not need to be manually held in an open position. In cases in which the package is a bag or pouch made of flexible material, for example, the front and back panels of the package may need to be separated by the consumer to initially open the package and then held in the separated, open position while the consumer reaches inside the package to withdraw an item for consumption.
Accordingly, embodiments of the invention include an opening support disposed near the opening of the package that is designed to span a longitudinal seam of the package and maintain the package opening in a wide open configuration.
Accordingly, in some embodiments, a package is provided that includes a front panel defining an opening end, a base end, and two side edges, as well as a back panel defining an opening end, a base end, and two side edges. The back panel is connected to the front panel via longitudinal seams formed along respective side edges of the front and back panels. An opening support is disposed proximate the opening end of at least one of the front or back panels, and the opening support is configured to be moved from an inactive position to an active position. The opening end of the front panel and the opening end of the back panel define an opening of the package that is configured to provide access to contents of the package when the package is opened by a user. In the inactive position, the opening support is disposed along one of the front panel or the back panel, whereas in the active position, the opening support extends between the front panel and the back panel, across a corresponding longitudinal seam, to maintain the opening of the package in a wide-open position. In some cases, the package may further comprise a base panel connecting the base end of the front panel to the base end of the back panel, such that the package is a stand-up pouch.
The opening support may comprise a flexible strip of material defining a first end and a second end. In the inactive position, both the first end and the second end of the flexible strip of material may be removably attached to one of the front panel or the back panel. In the active position, the first end of the flexible strip of material may be removably attached to one of the front or back panels and the second end of the flexible strip of material may be removably attached to the other of the front or back panels, such that the flexible strip of material spans the corresponding longitudinal seam. Each of the first and second ends may include a region of pressure sensitive adhesive configured to removably attach the flexible strip of material to a respective one of the front or back panels.
In some embodiments, the opening support may comprise a flexible strip of material defining a first end and a second end, where, in the inactive position, the first end is fixedly attached to one of the front panel or the back panel and the second end is removably attached to the same one of the front panel or the back panel. In the active position, the second end may be configured to attach to the other of the front panel or the back panel, such that the flexible strip of material spans the corresponding longitudinal seam.
The second end may include a region of pressure sensitive adhesive configured to removably attach the flexible strip of material to a respective one of the front or back panels in the active position. Additionally or alternatively, an outer surface of a respective one of the front or back panels to which the second end is configured to removably attach may comprise a receiving feature configured to engage the second end. In some cases, the receiving feature may comprise a removable flap comprising a region of pressure sensitive adhesive configured to removably attach to the second end of the flexible strip of material in the active position. In other cases, the receiving feature may comprise a protrusion, and the second end of the flexible strip of material may comprise an indentation configured to engage the protrusion of the receiving feature in the active position.
In some embodiments, the opening support may be disposed on an outer surface of the package. In other embodiments, the opening support may be disposed on an inner surface of the package. The opening support may, in some cases, comprise a rigid member defining a fixed end and a free end, where the rigid member is configured to be moved between the inactive position, in which the rigid member is disposed along one of the front or back panels, and the active position, in which the rigid member extends across the longitudinal seam. The free end may be configured to engage a receiving member disposed on the other of the front or back panels when the opening support is in the active position. Moreover, the receiving member may comprise a groove configured to receive the free end of the rigid member to lock the rigid member in the active position.
In other embodiments, a method of manufacturing a package including an opening support is provided. The method includes forming a front panel defining an opening end, a base end, and two side edges and attaching a back panel defining an opening end, a base end, and two side edges to the front panel via longitudinal seams formed along respective side edges of the front and back panels. An opening support is disposed proximate the opening end of at least one of the front or back panels, and the opening support is configured to be moved from an inactive position to an active position. The opening end of the front panel and the opening end of the back panel define an opening of the package that is configured to provide access to contents of the package when the package is opened by a user. In the inactive position, the opening support is disposed along one of the front panel or the back panel, and in the active position, the opening support extends between the front panel and the back panel, across a corresponding longitudinal seam, to maintain the opening of the package in a wide-open position.
In some cases, the opening support may comprise a flexible strip of material defining a first end and a second end. In the inactive position, both the first end and the second end of the flexible strip of material may be removably attached to one of the front panel or the back panel, and, in the active position, the first end of the flexible strip of material may be removably attached to one of the front or back panels and the second end of the flexible strip of material may be removably attached to the other of the front or back panels, such that the flexible strip of material spans the corresponding longitudinal seam. A pressure sensitive adhesive may be applied to at least one of the first or second ends to form a respective region of pressure sensitive adhesive that is configured to removably attach the flexible strip of material to a respective one of the front or back panels.
Additionally or alternatively, a receiving feature may be applied to an outer surface of a respective one of the front or back panels to which the second end is configured to removably attach, where the receiving feature is configured to engage the second end. Applying the receiving feature may comprise forming a protrusion that extends outwardly from the outer surface of the respective one of the front or back panels, the method may further comprise forming an indentation in the second end of the flexible strip of material that is configured to engage the protrusion of the receiving feature in the active position. In some embodiments, the opening support may comprise a rigid member defining a fixed end and a free end. The rigid member may be configured to be moved between the inactive position, in which the rigid member is disposed along one of the front or back panels, and the active position, in which the rigid member extends across the longitudinal seam.
Having thus described the disclosure in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present invention now will be described more fully hereinafter with reference to the accompanying drawings in which some but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
Conventional packages made of flexible materials, such as various polymer-based materials, are often used to hold food products, such as baking ingredients (e.g., sugar, flax seed, oatmeal, etc.), snack foods (e.g., trail mix, nuts, fruit pieces, chips, etc.), and other bulk materials. Examples of such packages are illustrated in
Either way, a consumer may open the package by separating the front and back panels 10, 20, such as by opening a closure feature 50 (e.g., a zipper or tongue-and-groove mechanism) that joins the opening ends 16, 26 of the front and back panels together (see
Due to the thickness and/or resilient properties of the materials used to form the front and back panels 10, 20 of such packages, the opening 60 of the package (shown in
Accordingly, embodiments of the present invention provide a built-in opening support that can be actuated by the user to maintain the package in an open or wide-open configuration, thereby preventing or reducing the need to manually keep the front and back panels of the package separated as product is accessed. In this regard, the wide-open position of the opening of the package may be considered a configuration of the opening (e.g., size, shape, and/or spacing) that allows a consumer to easily reach into the package to withdraw product, without the need for further widening the opening. Embodiments of the invention are applicable in, and may be embodied by, various kinds of packages including stand-up pouches (e.g.,
With reference now to
In some cases, such as in the embodiment of
Said differently, a consumer would purchase the package with the opening support 100 in the inactive position. In the example shown in
The flexible strip of material may be, for example, a strip of polymer material, such as polyethylene (PE) or polyethylene terephthalate (PET), polypropylene (PP), oriented polypropylene (OPP), nylon, biaxially oriented nylon (BON), etc. In some cases, each of the first and second ends 105, 110 of the opening support 100 may include a region of pressure sensitive adhesive 120 (shown on the first end 105 in
In this regard, the opening support 100 may, in some cases, be cut out of the material forming one of the layers of the package itself. In the case of a package formed from a laminate structure having an outer film layer and one or more inner film layers, for example, the opening support 100 may be part of the outer film layer and may be defined via laser scoring or die cutting the shape of the opening support out of the outer layer. The pressure sensitive adhesive 120 may thus be pattern applied between the outer film layer and an adjacent layer of the laminate structure in the area of the opening support 100. The PSA may remain with the opening support 100, thereby allowing the user to re-apply the opening support across the longitudinal seam 30 as described above after it has been peeled away from the outer film layer. In other embodiments, however, the opening support 100 may be an additional strip of material that is removably attached to the outer surface of the package (e.g., via adhesive), such as to the outer surface of an outer film layer of the package.
With reference now to
In this regard, the flexible strip of material 130 may include a notch 132 or other hinge feature, such as a living hinge, that allows the flexible strip to bend at the location of the feature and, thus, facilitates a user's movement of the second end 140 from its original, inactive position (
In some cases (not shown), the second end 140 of the flexible strip of material 130 may include a region of pressure sensitive adhesive, such as on an outward-facing surface of the second end when the opening support is in the inactive position of
In still other embodiments, however, the region of pressure sensitive adhesive may be provided on an inward-facing surface of the second end when the opening support is in the inactive position, such that it is not exposed and need not be protected by a liner. When moved towards the active position, the flexible strip of material 130 may be folded over itself twice (e.g., once proximate the first end 135 and once proximate the second end 140), such that the pressure sensitive adhesive ends up facing the outer surface of the respective panel (e.g., the back panel 20). This is illustrated in
In other cases, such as in the example depicted in
In some cases, such as in applications where the package is not designed to be reusable, adhesives other than pressure sensitive adhesive may be used in the embodiments described above with respect to
Turning to
Although the receiving feature 150 is shown and described above as a flap 155 with pressure sensitive adhesive 160 in some embodiments and as a protrusion 151 in other embodiments, various types of receiving features may be used, including hooks, loops, slits, etc. provided on one or both of the flexible strip of material 130 and/or the receiving feature 150 itself.
As described above and depicted in
In some cases, the free end 174 of the rigid member 170 may be configured to engage a receiving member 150 disposed on the other of the front or back panels (e.g., the back panel 20 in the depicted embodiment) when the opening support is in the active position, as shown in
Although in the embodiments of
Embodiments of a method of manufacturing a package including an opening support as described above are also provided herein. The method may, for example, comprise forming a front panel defining an opening end, a base end, and two side edges and attaching a back panel defining an opening end, a base end, and two side edges to the front panel via longitudinal seams formed along respective side edges of the front and back panels. An opening support may be disposed proximate the opening end of at least one of the front or back panels, where the opening support is configured to be moved from an inactive position to an active position. The opening end of the front panel and the opening end of the back panel may define an opening of the package configured to provide access to contents of the package when the package is opened by a user. As described above, in the inactive position, the opening support may be disposed along one of the front panel or the back panel, whereas in the active position, the opening support may extend between the front panel and the back panel, across a corresponding longitudinal seam, to maintain the opening of the package in a wide-open position.
As described above, the opening support may comprise a flexible strip of material defining a first end and a second end, wherein, in the inactive position, both the first end and the second end of the flexible strip of material are removably attached to one of the front panel or the back panel. In the active position, the first end of the flexible strip of material may be removably attached to one of the front or back panels and the second end of the flexible strip of material may be adhered to the other of the front or back panels, such that the flexible strip of material spans the corresponding longitudinal seam.
In some embodiments, the method may include applying pressure sensitive adhesive to at least one of the first or second ends to form a respective region of pressure sensitive adhesive configured to removably attach the flexible strip of material (or a portion thereof) to a respective one of the front or back panels. In still other embodiments, a receiving feature as described above may be applied to an outer surface of a respective one of the front or back panels to which the second end is configured to removably attach. The receiving feature may be configured to engage the second end, such that the package is maintained in the open configuration.
For example, applying the receiving feature may comprise forming a protrusion that extends outwardly from the outer surface of the respective one of the front or back panels, and the method may further include forming an indentation in the second end of the flexible strip of material that is configured to engage the protrusion of the receiving feature in the active position.
In still other cases, as described above, the opening support may comprise a rigid member defining a fixed end and a free end. The rigid member may be configured to be moved between the inactive position, in which the rigid member is disposed along one of the front or back panels, and the active position, in which the rigid member extends across the longitudinal seam.
