10017291
The present disclosure relates to packaging which is elderly friendly and includes child resistant features. The packaging may find particular benefit in the pharmaceutical industry for the retaining and dispensing of medications.
There is a continuous need for packaging which stores and dispenses pharmaceutical products, such as medications. As children may be attracted to packaging of medications, most pharmaceutical packaging uses a child resistant or child proof feature. Many child resistant features may be found difficult to overcome by the medication's intended user due to limited hand use. Limited hand use may be suffered by elderly individuals or other afflictions which may impact hand use or dexterity, such as arthritis. As such, there is a need for packaging that deters children from accessing the contents contained within the packaging, but yet may be convenient to access for persons having limited use of their hands.
U.S. Pat. No. 8,746,540 discloses child resistant packaging intended for pharmaceuticals. The packaging provides for an inner casing that is able to retract within an outer casing. The inner case is provided with a raise edge that engages with a corresponding raised edge located on the inside surface of the outer casing and requires beings depressed to disengage the inner casing from the outer casing. The packaging further includes flaps which will rupture and release fragments of the box is tampered with. There is no disclosure relating to the ease of use of the packaging by an individual with limited hand use.
U.S. Pat. No. 8,827,145 discloses packaging with an inner and outer casing which may be used for carrying objects such as chewing gums comprising nicotine. The packaging includes a means of tamper evidence at a weakening line. To provide child resistant access, the packaging includes a lock member in which a raised edge is located on an outside wall of inner casing which engaged with a raised edge on the inside of the outer casing. To disengage the inner member from the outer member, the raised edge of the inner member is depressed thereby loosening engagement with the outer casing. There is no disclosure relating to the ease of use of the packaging by an individual with limited hand use.
U.S. Pat. No. 6,955,290 discloses packaging formed of a single blank having an outer contour unit and an inner contour unit suitable for retaining pharmaceuticals, such as pills. The inner contour unit may be displaced within the outer contour unit by a connecting folding tab capable of either folding a stretching. The material contained within the packaging may be removed from a removal opening in the inner contour unit. There is no teaching provided for tamper proofing the packaging or making the packaging child resistant.
There remains a need for packaging which is child resistant, to deter children from accessing the contents within the packaging, and simple enough to use for an individual with limited hand use. There remains a need from packaging that can be constructed from as few products as possible. There remains a need for packaging which may initially be formed in a flat, one-dimensional configuration and then formed into a three-dimensional configuration.

The fore-aft side wall at the front end of the inner casing may be the front side wall. An opposing fore-aft side wall may define the back end of the inner casing. The fore-aft side wall at the back end of the inner casing may be the back side wall. The lateral edges of the front side wall and/or back side wall may be adjacent to the lateral edges of the lateral side walls. The lateral edges of the front side wall and/or back side wall may be the same as the lateral edges of the lateral side walls. The inner casing may have a hollow interior. The surfaces of the inner casing may have interior faces facing toward the hollow interior and exterior faces that are exposed. The exposed surfaces may be a show surfaces. The interior surfaces may be suitable for being in direct contact with pharmaceutical products. The surfaces of the inner casing may include surfaces comprised of, or at least partially comprised of, more than one layer of material.

The width of the inner casing may be less than the width of the outer casing. The length of the inner casing may be less than, equal to, or greater than the length of the outer casing.
Each casing of the container may comprise a blank. The blank may be a continuous sheet. Only one blank may be needed per casing. The blank may include a plurality of fold lines. The blank, prior to folding along the fold lines, may be initially flat. The blank's flat configuration may be a casing's one-dimensional configuration. The blank may be folded along the fold lines to form a casing's three-dimensional configuration. The blank may include an exterior facing surface. The blank may include an interior facing surface. The fold lines may divide the blank into panels. When the blank is folded, the panels may form all or part of a casing's surfaces and/or walls. The panels may form other features of the casing, such as locking features, retention features, closing features, or a combination thereof.
A blank for each casing may include regions having creases, regions having slits, regions having perforations, or any combination thereof. Creases preferably are employed in areas that provide a structural feature, such as a connection between two adjacent side walls or where a side wall meets a top or bottom surface. Creases are also preferably employed to allow easy folding, defined folding, or both in regions that will be visible in the individual assembled casings or overall container. Preferably, the assembled container is free of visible slits or perforations. Perforations and/or slits preferably are employed for folding in regions that are not visible in the assembled container and may not be required to provide a structure between the areas on either side of the fold. Creases, slits, perforations, and the combination thereof may be referred to as fold lines.
The container may comprise one or more dispense apertures. The dispense aperture may be located on a surface of the inner casing and/or a surface of the outer casing. Preferably, the dispense aperture is on a surface of the inner casing. The dispense aperture may be sized to allow material contained within the inner casing to be dispensed from the inner casing. For example, if tablets or chewing gum are stored within the inner casing, the dispense aperture may be sized larger than the tablets or chewing gum. The dispense aperture may be formed by removing a perforated portion from the casing. For example, a perforated pattern, such as an oval or circle, may be located on a surface of the casing. A user may then apply force to the perforated surface, such as pressing down on the surface, thereby piercing the perforations which allows a portion of the surface to be removed and thereby creating the dispense aperture. The dispense aperture may be located on a side wall, top surface, bottom surface, or combination thereof of the inner casing. The dispense aperture may be placed along the length of the inner casing, such that it is not exposed when the inner casing is fully retracted within the outer casing. For example, when the container is in the closed configuration, the outer casing blocks access to the dispense aperture or prevents the materials stored within the inner casing from falling out. A dispense aperture may be located on both the inner casing and outer casing. The dispense apertures may be offset from one another when the container is in the closed configuration, such that a surface of the outer casing blocks an aperture of the outer casing, and the aperture in the outer casing only exposes an exterior surface of the inner casing. The inner casing may be withdrawn from the outer causing such that the aperture in the inner casing aligns with an aperture in the outer casing, thereby allowing the materials contained within the inner casing to be dispensed.
The inner casing may include a locking tab. The locking tab may be any feature that engages with a feature of the outer casing to prevent the inner casing from being withdrawn from the outer casing. The locking tab may be any feature that deters a child from removing the inner casing from the outer casing. The locking tab may be a panel of the continuous sheet or blank used to form the inner casing. The locking tab may be located on any surface of the inner casing, such as the top surface, bottom surface, side wall, or a combination thereof. The locking tab may be located on any surface's exterior of the inner casing. The locking tab may be a projection from any surface of the inner casing, such as the top surface, bottom surface, side wall, or combination thereof. The locking tab may be integrally connected to any surface or panel of the inner casing. The locking tab may be integrally connected via a fold line such that it is hingedly connected to a surface of the casing. The fold line may allow the locking tab to fold into planar contact with an adjacent surface. For example, the locking tab may project from the top surface of the inner casing at a fold line, which allows the locking tab to fold down into planar contact with a side wall of the inner casing. The locking tab may have a back end and a front end. The back end may be close to the back end of the inner casing than the front end. The locking tab may have a length defined as the distance from its back end to its front end. The locking tab may have any length that allows it to engage with a feature of the outer casing.
The outer casing may include a locking layer. The locking layer may be any feature located within the interior of the outer casing that retains the inner casing retracted within the outer casing. The locking layer may be any feature that engages with a feature of the inner casing, such as the locking tab, to prevent the inner casing from being withdrawn from the outer casing. The locking layer may be any feature that engages with a feature of the inner casing to deter a child from removing the inner casing from the outer casing. For example, the locking layer may engage with the locking tab of the inner casing. The locking layer may be a lateral projection from any surface of the outer casing, for example the locking layer may project from the top surface, bottom surface, side wall, or combination thereof. The locking layer may be integrally connected to a surface of the outer casing, such as by a fold line. The locking layer may be comprised of a panel of the blank which forms the outer casing. The locking layer may be any material which may form at least one additional layer in the interior of the outer casing. For example, if the locking layer is a lateral projection or panel, it may fold inward into the inside of the outer casing. The lateral projection or panel may then be adhered, such as with an adhesive, into planar contact with an interior surface of side or panel of the outer casing. The locking layer may have a front end and a back end. The front end may be where the locking layer is integrally connected at the fold line to a surface of the outer casing or the end of the locking layer closest to the front end of the outer casing. The back end may be the end of the locking layer opposing the front end. The locking layer may have a length defined as the distance between the front end and the back end. The locking layer may have a length such that when the inner casing is fully retracted within the outer casing, the back end of the locking layer may be distanced from the front end of the locking tab or the back end of the locking layer may be adjacent and in contact with the front end of the locking tab, preferably the locking tab is not overlapping with the locking layer. When the inner casing is fully retracted within the outer casing, the back end's exterior surface may be adjacent and in contact with the outer casing's back end interior surface. The locking layer may prevent the inner casing from being withdrawn from the casing by impeding movement of the locking tab. For example, the back end of the locking layer may block forward movement of the locking tab, thereby preventing forward movement of the inner casing.
The container may comprise a lock disengagement. The lock disengagement may be any feature or combination of features in the outer and/or inner casing that allows the locking tab to overcome the locking layer. The lock disengagement may by any feature that allows the inner casing to be withdrawn from the outer casing. The lock disengagement may be any feature that may be simple to use, such that an individual with limited hand use may still be able to withdraw the inner casing from the outer casing. The lock disengagement may include a cut-out in a surface of panel of the outer casing. The lock disengagement may provide a surface area for a user to press inward on. By pressing downward on the lock disengagement, pressure may be applied to the locking tab such that the tab moves inward toward the center of the container. By pressing downward on the lock disengagement, pressure may be applied to the locking tab such it can be distanced from the locking layer and thereby may be able to bypass the locking layer as force is applied to the inner casing to withdrawn the inner casing from the outer casing. The lock disengagement may include a cut-out in a surface of panel of the outer casing. The cut-out may be located adjacent to the locking layer on the same surface, side, or panel of the as the locking layer. For example, the cut-out may be located adjacent the back end of the locking layer. The cut-out may be located in between the locking layer and the lock disengagement surface. The cut-out may allow inward pressure to be applied to the same surface the locking layer is located on without having inward pressure applied to the locking layer. The cut-out may allow only a portion of the outer casing's surface to deform inward from pressure. For example, the cut-out may restrict pressure from traveling across the entire surface to which the pressure is applied to. By placing the cut-out adjacent to the locking layer on the same surface, when applying pressure on the side of the cut-out furthest from the locking layer's back end, the outer casing's surface may be temporarily deformed thereby temporarily deforming a surface of the inner casing. By deforming a surface of the inner casing, the locking tab is distanced away from the surface of the outer casing having the locking layer. By placing the cut-out adjacent to the locking layer on the same surface, the locking layer remains in a substantially steady position instead of also deforming inward, which may allow distance to form between the locking tab and locking layer. The distance formed between the locking layer and locking tab may allow the locking tab to move past the locking layer which may allow the inner casing to be withdrawn from the outer casing.
The container may comprise a retention feature. The retention feature may be any feature that retains the inner casing partially within the outer casing. The retention feature can be located on the exterior surface of the inner casing, the interior surface of the outer casing, or a combination of both. The retention feature may be any feature that does not prevent the lock disengagement from disengaging the locking tab from the locking layer and permitting the inner casing from being withdrawn from the outer casing. The retention feature may restrict how far the inner casing may be withdrawn from the outer casing, such that the inner casing is not completely withdrawn from the outer casing during normal use.
The casings may include one or more lateral projections that project from a lateral peripheral edge of a side wall layer, an edge of the top surface, and/or an edge of the bottom surface. Such projections may be a tab or other feature capable of orienting in a direction so that it forms either part of or substantially a side wall, more than one side wall, or part of a layer of a side all. A lateral projection may provide reinforcement to a side wall. A lateral projection may provide reinforcement for a corner.
The container may include an adhesive for attaching some or all of a face of a blank to a surface of the same blank. For example, adhesive may be employed for attaching a blank's panel to another panel. Adhesive may be employed for closing a casing. Adhesive may be employed for attaching a feature to a blank. For example, adhesive may be used for affixing the locking layer to the outer casing. Further, adhesive may be used to affix a locking tab to the inner casing. Adhesive may be used to affix printed material, such as medical information, on the exterior surface(s) of the casing(s). The adhesive may be provided to one or both of the faces to be attached. The adhesive may be selected to provide a durable adhesion to the surfaces being attach. The adhesive may be characterized as a glue, a curable adhesive, a non-polar adhesive, a reactive adhesive, an adhesive that covalently bonds to a surface, an adhesive that bonds to a surface with van der Waals forces, or any combination thereof. The adhesive may be provided on the entirety of a surface or on a portion of a surface. For example, the adhesive may be provided as a pattern on a surface, a uniform layer, irregularly, along a periphery of a surface, or any combination thereof.
At least one or more surfaces of the blank, may be adapted for printing directly on its surface. Preferably at least one of the exterior facing surfaces of the outer casing is adapted for printing directly on its surface. Preferably at least one of the exterior facing surface of the inner casing is adapted for printing directly on its surface. When a blank is folded into a casing, it may include a show surface. The show surface may be the blank's exterior facing surface which is visible after folding. For example, two layers of one surface may each have an exterior facing surface, but only one layer will be visible on a casing's exterior to result in a show surface. When folded into a casing, the blank may have hidden surfaces. For example, surfaces of a layer that have been covered by another layer. When folded into a casing, preferably none of the hidden surface is visible. Nevertheless, it may be advantageous to have printing on a hidden surface so that instructions or other features may be provided on that surface. It is also possible to fold the continuous sheet and/or employ openings is a sheet so that portions of both faces are visible.
The blank may be formed of any material or combination of materials capable of being folded to form multiple layers of the casing's components, such as multiple layers of walls.
The blank may have a first face and a second face. The thickness of each blank may be the distance between the two opposing faces. The thickness may be uniform or it may vary. Preferably each blank has a thickness that is sufficiently uniform so that it can be made from stock materials (e.g., card stock, sheet stock, or cardboard) or other material having generally uniform materials. As used herein, a sheet having a uniform thickness has a thickness with a standard deviation of about 205 or less, about 10% or less, about 5% or less, or about 15 or less. For example, the standard deviation of the thickness may be about 0%.
Each blank may be formed by die cutting a sheet stock material. As such, the blank, may be die cut preform for a container. Any material suitable for folding, die cutting, or both may be employed. The blank may be a single layered material or may have multiple layers. For example, the blank may include a layer of a polymer, a layer of a paper, a corrugated medium, or any combination. A particularly preferred material is a paperboard. Another particularly preferred material is cardboard. Any paperboard or cardboard may be employed. A combination of two or more materials may be employed. The inner casing blank and the outer casing blank may be comprised of the same material or different materials. The thickness of the material is preferably about 0.1 mm to about 5 mm, and more preferably 0.2 mm to about 3 mm. The thickness of the material is preferably sufficiently high so that each casing can be assembled without having to fold an excessive number of layers for each surface. As an example, if the blank material includes a paperboard, the paperboard may be characterized as about 8 point, 10 point, about 12 point, about 14 point, about 16 point, about 18 point, about 20 point, about 22 point, about 24 point, or about 26 point, about 28 point, about 30 point, or about 32 point. As another example, if the blank material includes a cardboard, the cardboard may be characterized as single face board, single wall board, double wall board, or even triple wall board. If the blank material includes a cardboard, the cardboard may be characterized as C-Flute, B-Flute, E-Flute, F-Flute, or R-Flute.
Each casing may include any number of layers, top surface layers, bottom surface layers, and/or side wall. For example, the bottom surface or top surface of either or both the inner casing and outer casing may be partially comprised or substantially comprised of a plurality of layers. For example, one or more of the side walls of either or both the inner casing and outer casing may be partially comprised or substantially comprised of a plurality of layers. The layers may be formed from multiple panels of the blank. If a single layer may have insufficient strength to support the container, by using a plurality of stacked layers, a container having sufficient strength may be achieved. Layers may be used to provide additional features of the inner or outer casing, for example, by layering the panels on a side wall, the locking layer may be formed. Each side wall may have the same number of side wall layers or may differ in the number of side wall layers.
The components described in the teachings herein may be used for preparing a container having a generally polygonal base with n sides, where n is 3 or more. Containers that are employed having a box compartment often have n=4 sides. As such, the teachings focus on such containers, more particularly having rectangular bases. However, it should be appreciated the teachings herein can also be applied to containers having different number of sides, having one or more sides that is not parallel to another side, having an even number of sides, or having an odd number of sides, or having one or more sides with a length differing from one or all of the other sides, or any combination thereof. The base of the container may generally be thought of as being positioned on a horizontal plane. The base may be generally flat. However, the base may be formed to have minor amounts of curvature. The container generally has upright side walls rising vertically from the base portion. The height of the upright side walls will generally be uniform for a given upright side and constant between the upright side walls. However, containers in which one or more upright side walls vary in height and/or in which one or more side walls have a height that is different from the height of an opposing upright side wall may also be employed. By way of example, a container may include a generally rectangular base having four side walls, including a first side wall with a first height, an opposing side wall having a second height (e.g., greater than the first height), and adjacent side walls that vary in height (e.g., between the first height and the second height).
The disclosure further relates to a method of forming the container according to the teachings herein. The method may comprise: folding a first blank along a plurality of fold lines to form a plurality of walls which project orthogonally from a plurality of edges along a perimeter of the container's top surface and bottom surface; applying adhesive to one or more surfaces of the first blank; folding a second blank along a plurality of fold lines to form a plurality of walls which project orthogonally from a plurality of edges along a perimeter of the container's top surface and bottom surface; applying adhesive to one or more surfaces of the first blank; forming an outer casing from the first blank; forming an inner casing from the second blank; and inserting the inner casing into the outer casing.
Though not necessarily drawn to scale, all geometries relative proportions and dimensions shown in the drawings are also part of the teachings herein, even if not explicitly recited. However, unless otherwise noted, nothing shall limit the teachings herein to the geometries, relative proportions, and dimensions shown in the drawing.
Unless stated otherwise, dimensions and geometries of the various structures depicted herein are not intended to be restrictive of the invention, and other dimensions or geometries are possible. Plural structural components can be provided by a single integrated structure. Alternatively, a single integrated structure might be divided into separate plural components. In addition, while a feature of the present invention may have been described in the context of only one of the illustrated embodiments, such feature may be combined with one or more other features of other embodiments, for any given application. It will also be appreciated from the above that the fabrication of the unique structures herein and the operation thereof also constitute methods in accordance with the present invention.
The preferred embodiment of the present invention has been disclosed. A person of ordinary skill in the art would realize however, that certain modifications would come within the teachings of this invention. Therefore, the following claims should be studied to determine the true scope and content of the invention.
The explanations and illustrations presented herein are intended to acquaint others skilled in the art with the invention, its principles, and its practical application. Those skilled in the art may adapt and apply the invention its numerous forms, as may be best suited to the requirements of a particular use. Accordingly, the specific embodiments of the present invention as set forth are not intended as being exhaustive or limiting of the invention. The scope of the invention should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description.
