BACKGROUND OF THE INVENTIONDevices for packing and shipping products and/or containers of products are known. Such devices are available in a wide variety of shapes, sizes and styles. Often a package is designed to contain a number of different containers, such as several containers of a product, in a single package for delivery from one location to another, such as from a manufacturer to a wholesaler or retail seller. Sometimes the shipping package is also used to display the product once the shipping package is opened at the retail seller.
There remains a need for a cost effective low-bulk package which is capable of shipping a small number of containers, and which transitions to a display package and/or is capable of readily transferring the containers directly onto a display shelf, without a need for cutting or tearing of the cardboard or other fairly rigid material of the package, and provides full consumer view and access to the containers, yet also meets the strength, durability, palletizing, and general industry standards for shipping packages of like containers to market.
Without limiting the scope of the invention, a brief summary of various embodiments of the invention is set forth below. Additional details of the summarized embodiments of the invention and/or additional embodiments of the invention may be found in the Detailed Description of the Invention below.
A brief abstract of the technical disclosure in the specification is provided as.
BRIEF SUMMARY OF THE INVENTIONIn one embodiment, the invention is directed to a container package assembly which includes a plurality of trays for supporting containers thereon, a top pad which is placed over the containers and at least one layer of encapsulating film which at least partially covers the combination top pad, containers and trays. The package may be used for shipping and, optionally, for retail display.
In at least one embodiment of the invention, the container package assembly comprises two or more trays which are positioned horizontally adjacent to one another. A plurality of containers is disposed on each tray and a top pad extends atop the containers over at least a portion of each of the trays. The trays, containers and top pad are at least partially encapsulated by a polymeric packaging film such as shrink-wrap, stretch-wrap, plastic or other type of thin pliable membrane. The top pad provides stability to the individual containers positioned on the trays during distribution of the shipping package as well as maintaining stability of the entire package by structurally linking the two independent trays.
The top pad, in accordance with the invention, typically has a surface area equal to or less than the area of the tray positioned there under.
Typically, the trays comprise a fairly rigid horizontal support surface. Desirably, the trays may have one or more vertical sides or walls to help retain the containers on the horizontal support surface. These side walls function to retain the containers on the horizontal support surfaces during the packaging process, during distribution, and during the transfer of the display package to the retail shelf. The walls may be of uniform height, may be tapered, or may have other configurations.
In at least one embodiment a tray is provided with three side walls and one “open” side.
In some embodiments the product containers to be placed on the tray have a tapered shape such that the bottom of the product container that sits on the support surface of the tray has a smaller diameter than the top of the product container. Where such tapered product containers are present the vertical sides of the tray are constructed to arranged to engage at least a portion of the tapered sides of the product containers adjacent thereto. In some embodiments the length and/or width of the horizontal support surface is less than the effective length and/or width of the arranged tops of the product containers.
In some embodiments the assembly comprises a single tray.
In some embodiments the top pad and/or layer of encapsulating film are optional or not a required component of the assembly.
In some embodiments the assembly is encapsulated in a shipping material other than encapsulating film. For example, in at least one embodiment one or more trays and their associated containers, are placed within or encapsulated in a cardboard or corrugated cardboard box.
In at least one embodiment the tray is provided with an adhesive on its surface to at least temporarily engage one or more rows of the product containers positioned thereon. In some embodiments the adhesive is may be a permanent or temporary adhesive, such as a removable adhesive, time release adhesive, biodegradable adhesive and/or any combination thereof. In some embodiments all of the product containers on the tray are at least temporarily affixed to the tray. In some embodiments only some product containers are at least temporarily affixed to the tray.
In some embodiments the temporary adhesive is in the form of a line or strip of temporary adhesive which engages the row of products proximate to the open side of the tray. In some embodiments the temporary adhesive is placed in a series of individual distinct spots on the tray surface, with each point corresponding to the eventual position of a single product container.
Further aspects of the invention will become apparent form the detailed description which follows.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGSA detailed description of the invention is hereafter described with specific reference being made to the following drawings.
While this invention may be embodied in many different forms, there are described in detail herein specific embodiments of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiments illustrated.
For the purposes of this disclosure, unless otherwise indicated, identical reference numerals used in different figures refer to the same component.
An embodiment of the inventive container package assembly is shown generally at 10 in
The containers 20 may be arranged on a tray 12 in any manner desired. For improved stability and strength, the containers are preferably arranged in a uniform pattern of rows and or columns. Such an arrangement has the added benefit of providing ready viewability and ease of access when the trays 12 of containers 20 are placed in a retail environment.
Once the containers 20 are placed on the trays 12 in a desired arrangement, a top pad 22 is placed on top of the containers 20. The top pad 22 may have a horizontal surface 24 having an area which extends at least partially over each of the trays 12. The horizontal surface 24 of the top pad 22 may be greater than, equal to, or less than the area of the combined trays 12 positioned there under. Typically, the top pad will have an area slightly less than the combined area of the trays over which the top pad extends. Once the top pad 22 is in place on top of the containers 20, the combined assembly of trays 12, containers 20, and top pad 22 may be in-whole or in-part encapsulated by a film 30.
The top pad 22 forms a supporting linkage between the trays 12. The top pad 22 may further act as a cutting surface once the package assembly 10 is received in a retail environment. The film 30 may be cut and opened, through application of a knife or other cutting means. The presence of the top pad 22 prevents the cutting means from contacting and damaging the containers 20 positioned there under. After the film 30 is cut and the assembly 10 opened, the top pad 22 may then be removed from the containers 20, and the two independent trays 12 may be used as shelf ready displays.
While the use of a top pad 22 is often desired to provide additional support and structural rigidity to assembly configurations, such as those depicted in
In the various embodiments of the invention where the package 10 includes an encapsulating film 30, the film 30 may be any type of retaining film or material. For example the film 30 may be shrink-wrap, stretch wrap, plastic sheeting or netting, or any other type of retaining material. The film 30 may partially or entirely encapsulate the entire combination of trays 12, containers 20, and the optional top pad 22, such as is in the manner shown in
In the various embodiments shown and described herein each tray 12 comprises a horizontal support surface 40 upon which the containers 20 are placed along with the three side walls 14 and an open side 16. A three-walled tray provides improved stability while ensuring that the “front” or label information of the containers 20 is fully exposed for retail viewing.
As shown in
The inclusion of walls 14 on the trays 12, improves the stability of the package 10, by confining the containers 20 within the confines of the tray 12. The use of walls 14 may help retain the containers 20 on the trays 12 even when the film 30 is removed. As is discussed in greater detail below the height of the walls as well as their proximity to the product containers 20 also affects stability of the package 10.
In the embodiments shown in
As mentioned above, in multiple tray package assemblies, such as those depicted in
For example, in the embodiment shown in
Depending on the nature of the product containers, the shipping conditions, display conditions, etc. it may be more cost effective to eliminate the top pad from the assembly 10 such as in the manner shown in
Reducing the components of the package assembly 10, by avoiding the use of a top pad and/or encapsulating film may naturally provide for a less stable shipping package. Such instability however may be offset in a number of ways. For example in the embodiment depicted in
In some embodiments however the particular dimensions of the support surface 40 of the tray 12 is not as significant to pack stability as the relationship between the product containers 20 and the side walls 14. For example, as is shown in
With such tapered containers 20 the dimensions of the support surface of the tray 12 may be configured to substantially match the general length and width dimensions of the arranged of the container bases 52. However in such an embodiment the side walls 14 would necessarily be forced to angle outward from the support surface 40 in order to follow the angle defined by the sides 50 of the product containers 20. An alternative configuration is that which is shown in
The engagement of the side walls 14 against the sides 50 of the tapered containers 20 may be made more secure by providing the package assembly 10 with encapsulating film 30 such as is shown in
As discussed above the stability, strength, and other characteristics of the package assembly may be modified or enhanced through the use of particular tray configurations, product container configurations, the optional use of a top pad, encapsulating film, etc. Yet another way in which the stability of the package assembly may be improved is through the use of one or more adhesives between the tray and the product containers contained placed thereon.
Any type of adhesive may be used to secure product containers 20 to the support surface 40 of the tray 12. It is preferable however, particularly in applications wherein the product containers 20 will eventually be placed in a retail setting, that the adhesive be a temporary bond self-removing adhesive, a time release adhesive, a biodegradable adhesive, etc. Some examples of suitable adhesives are described in U.S. Pat. Nos. 6,182,422, 6,499,596; as well as in U.S. Pub. App. No. 2003-0150760-A1 the entire contents of each of which are incorporated herein by reference. In at least one embodiment the adhesive is a temporary bond self-releasing adhesive with a viscosity of less than about 1800 centipoises. In some embodiments the temporary bond self-releasing adhesive has a viscosity of less than about 1500 centipoises.
In typical packaging systems, an adhesive is applied to the packaging substrate in one or more strips or “lines” which are positioned to correspond to each row or column of product containers so that all of the containers are adhesively engaged to the packaging substrate. While engagement of all of the containers to the substrate in this manner provides for a high degree of stability between the substrate and product, engagement of all the containers to the substrate is may not be necessary For example, in the embodiment depicted in
In at least one embodiment, an example of which is shown in
In some embodiments of the invention, particularly those wherein the adhesive described above is utilized, a tray 12 and its associated product containers 20, may be readily placed within a box or other conventional shipping container 70 such as is shown in
If desired the tray 12 and product containers 20 may be provided with a top pad and/or encapsulating film in the manner previously described.
As indicated the shipping container 70 may be any type of conventional shipping container, such for example a corrugated cardboard box, a wooden shipping container, etc. Any type of container may be utilized in the manner shown in
As illustrated in
As shown in
As previously mentioned, the three-sided tray 12 described above is particularly suited to act as a display tray in a retail setting. It is recognized however, that in some retail settings it is preferable to place the product containers 20 directly onto a display shelf 90 such as is shown in
In such instances, the open side 16 of the three-sided tray 12 makes it particularly easy to unload product containers 20 directly from the tray 12 to the display shelf 90 with a minimum of effort. As is shown in
In the various embodiments depicted herein, the assembly may be provided with any of a variety of containers, which may be varied in size, shape, number, and arrangement. Similarly, the support members, including the walls thereof and the top pad may likewise be provided in a variety of shapes and sizes.
The above disclosure is intended to be illustrative and not exhaustive. This description will suggest many variations and alternatives to one of ordinary skill in this art. All these alternatives and variations are intended to be included within the scope of the claims where the term “comprising” means “including, but not limited to”. Those familiar with the art may recognize other equivalents to the specific embodiments described herein which equivalents are also intended to be encompassed by the claims.
Further, the particular features presented in the dependent claims can be combined with each other in other manners within the scope of the invention such that the invention should be recognized as also specifically directed to other embodiments having any other possible combination of the features of the dependent claims. For instance, for purposes of claim publication, any dependent claim which follows should be taken as alternatively written in a multiple dependent form from all prior claims which possess all antecedents referenced in such dependent claim if such multiple dependent format is an accepted format within the jurisdiction (e.g. each claim depending directly from claim 1 should be alternatively taken as depending from all previous claims).
