This invention relates to packaging assemblies, and, more particularly, packaging assemblies which include a plurality of adjoined individual packages that can be configured in a nested manner.
Demand exists for unique packaging solutions, especially for various consumer packaged goods. Unique packaging solutions can desirably provide a combination of required functionality and distinctive aesthetics, for example, to preserve the quality and freshness of the product while also serving to reinforce attributes of a particular brand and differentiate a particular product in the eyes of consumers.
Increasingly, demand exists for consumer packaged goods such as foods or snacks to be packaged in individual serving sizes. Non-limiting examples of such food or snack products include yogurt, pudding, applesauce, fruit salad, gelatin products, ice cream, cheese snacks, oatmeal and other breakfast cereal, peanut butter, salsa, hummus, guacamole, other dips or spreads, vegetable salad, tuna salad, soup, pasta, and the like. Such individual serving size packaged products are often sold in multi-unit packs (i.e., packaging assemblies that include several individual serving size packages which are bundled together).
In general, available packaging options for multi-unit packs of individual serving size packages include rigid packaging and flexible packaging. For certain products or applications, rigid packaging such as cups or containers or trays can be a necessity or at least preferable over flexible packaging such as pouches. However, such multi-unit packs typically require a tradeoff between the amount or volume of product contained by the packaging relative to the space or volume occupied by the packaged product, especially if rigid packaging is required or preferred.
In particular, multi-unit packs of individual serving size rigid packages typically are less efficient as compared to single bulk rigid packages with respect to a ratio of the volume of product contained by the packaging relative to the volume of space occupied by the packaged product. Such a ratio equals one for packaging of a theoretically maximum efficiency (i.e., when the volume of product contained by the packaging equals the volume of space occupied by the packaged product). But, in practice, the ratio is something less than one for most packaged products, especially those packaged in rigid packages, because of inefficiencies. For multi-unit packs, such inefficiencies can include space occupied by the packaging itself as well as voids between bundled individual packages that can occur at least in part because of the spacing between the individual packages or the shape of the individual packages or other factors.
Inefficiencies that result in a lower ratio of the volume of product contained by the packaging relative to the volume of space occupied by the packaged product can lead to increased costs throughout the value chain. For example, shipping and warehousing can be more expensive for products packaged in the form of multi-unit packs of individual serving size rigid packages. Likewise, stocking multi-unit packs of individual serving size rigid packages on retailers' store shelves can be more expensive.
Indeed, given that retailers' shelf space typically is a limited and highly valuable resource, packaging solutions that deliver greater efficiency with respect to the ratio of the volume of product contained by the packaging relative to the volume of space occupied by the packaged product for multi-unit packs, and, especially those that do so while also providing distinctive aesthetics or increased surface area for presenting promotional information to consumers, would be highly beneficial to both retailers and the manufacturers which compete to have their products placed on retailers' limited shelf space.
Consequently, a need exists for packaging solutions, especially rigid packaging solutions, that can provide improved efficiency regarding the amount or volume of product contained by packaging assemblies such as multi-unit packs relative to the space or volume occupied by the packaging assemblies. A need also exists for packaging solutions to provide the aforementioned efficiency while also providing distinctive aesthetics or increased surface area for presenting promotional information to consumers.
The aforementioned needs are met by one or more aspects of the present invention.
One aspect of the invention is a packaging assembly including a plurality of individual packages. Each of the plurality of individual packages is adjoined to at least one other of the plurality of individual packages. The packaging assembly has a ratio of a packaged product volume to an occupied space volume that is at least 0.5 and less than 1.
Another aspect of the invention is a packaging assembly such as the aforementioned packaging assembly wherein at least a first package is adjoined to at least a second package by a hinged connection. Such a packaging assembly can be nested. That is, for example, the first package can be rotated relative to the second package about the hinged connection such that at least a portion of the base of the first package is adjacent to at least a portion of the sidewall of the second package.
Yet another aspect of the invention is a packaging assembly such as the aforementioned packaging assembly wherein each of the plurality of individual packages has a base and an opening that are both substantially L-shaped.
A further aspect of the invention is a packaging assembly such as the aforementioned packaging assembly wherein each of the plurality of individual packages has a base and an opening that are both substantially rectangular.
An even further aspect of the invention is a packaging assembly such as the aforementioned packaging assembly which includes a secondary exterior package that encases at least a portion of the plurality of individual packages. The secondary exterior package can contribute to bundling and/or securing the plurality of individual packages while also providing increased surface area for presenting promotional information to consumers.
Another aspect of the invention is a method of packaging a product. The method includes the steps of providing a packaging assembly such as the aforementioned packaging assembly, and filling the product into one or more of the plurality of individual packages.
Features of the invention will become apparent with reference to the following embodiments. There exist various refinements of the features noted in relation to the above-mentioned aspects of the present invention. Additional features may also be incorporated in the above-mentioned aspects of the present invention. These refinements and additional features may exist individually or in any combination. For instance, various features discussed below in relation to any of the described aspects of the present invention may be incorporated into any of the described aspects of the present invention alone or in any combination.
In some embodiments, the present invention is directed to a packaging assembly including a plurality of individual packages.
In other embodiments, the present invention is directed to a method of packaging a product.
Required and optional features of these and other embodiments of the present invention are described.
As used herein, the term “nested” means that a packaging assembly is configured whereby each individual package of the packaging assembly is rotated relative to at least one other individual package of the packaging assembly such that at least a portion of the base of the individual package is adjacent to at least a portion of the sidewall of the at least one other individual package.
As used herein, the term “occupied space volume” means the quantity of three-dimensional space taken up by a packaging assembly as determined by the product of multiplying the measured length by the measured width by the measured height of the exterior dimensions of the packaging assembly. For a packaging assembly with non-uniform dimensions, the maximum of each of the length dimension, width dimension, and height dimension is utilized.
As used herein, the term “packaged product volume” means the quantity of three-dimensional space that is intended to be available within the total of the cavities of the plurality of individual packages of a packaging assembly and can be filled by one or more products.
As used herein, the term “ratio of packaged product volume to occupied space volume” means the quotient of the packaged product volume divided by the occupied space volume for a given packaging assembly when the packaged product volume and the occupied space volume are expressed in the same unit of measurement.
As used herein, “unnested” means that a packaging assembly is configured in a manner that is not nested.
Packaging Assembly
A packaging assembly of the present invention includes a plurality of individual packages each of which is adjoined to at least one other of the plurality of individual packages.
The packaging assembly has a ratio of a packaged product volume to an occupied space volume that is at least 0.5 and less than 1. For example, the packaging assembly can have a ratio of packaged product volume to occupied space volume that is, in some embodiments, at least 0.50, and, in other embodiments, at least 0.51. In some embodiments, the packaging assembly can have a ratio of a packaged product volume to an occupied space volume that is at least 0.5 and also less than 1.0, or less than 0.9, or less than 0.8, or less than 0.7, or less than 0.6.
The packaging assembly can be in a nested configuration or an unnested configuration. However, to achieve a ratio of packaged product volume to occupied space volume that is at least 0.5, it is presently believed that the packaging assembly must be in a nested configuration.
The packaging assembly includes a plurality of individual packages. Packaging assemblies of the present invention are not limited to any particular number of individual packages, and a suitable number of individual packages can be determined by one of ordinary skill in the art without undue experimentation based on the specific requirements of the use or application of the packaging assembly. For example, the number of individual packages can be, in some embodiments, a multiple of two, and, in other embodiments, a multiple of three, and, in further embodiments, a multiple of four, and in even further embodiments, a multiple of six.
Each of the plurality of individual packages has a base, a sidewall integral with and extending from the base, and an opening defined by an end of the sidewall distal from the base. In some embodiments, the sidewall extends substantially perpendicularly from the base. For example, the angle between the base and the sidewall can be, for example, from about 75 degrees to about 115 degrees, or, for example, about 90 degrees.
The base, the sidewall, and the opening together define a cavity having an available volume into which one or more product can be added and thus packaged within the individual package. To enclose the product within the individual package until a time when the product is accessed by a consumer, the individual package can further include a closure, such as a removable closure, that covers and preferably removably seals the opening. Any suitable closure, including but not limited to a lid, a cap, a foil, or the like, can be employed.
Each of the plurality of individual packages has a three-dimensional shape. In some embodiments, the three-dimensional shape of at least one of the plurality of individual packages can be different from the three-dimensional shape of at least one other of the plurality of individual packages. In other embodiments, the three-dimensional shape of each of the plurality of individual packages can be substantially the same as the three-dimensional shape of each other of the plurality of individual packages. For example, in some embodiments, at least one of the plurality of individual packages has a base and an opening that are both substantially L-shaped, and, in other embodiments, at least one of the plurality of individual packages has a base and an opening that are both substantially rectangular. Alternatively, in some embodiments, each of the plurality of individual packages has a base and an opening that are both substantially L-shaped, and, in other embodiments, each of the plurality of individual packages has a base and an opening that are both substantially rectangular. In some embodiments, one or more of the plurality of individual packages is substantially rigid or semi-rigid.
Furthermore, each of the plurality of individual packages is adjoined to at least one other of the plurality of individual packages by a connection. In some embodiments, at least one individual package can be directly or indirectly adjoined to at least one, or two, or three, or four, or more other individual packages to provide a set of adjoined individual packages. The packaging assembly of the present invention can include one or more sets of adjoined individual packages, for example, at least two or more sets, or at least three or more sets, or at least four or more sets, which can be configured together in a nested manner.
In some embodiments, the connection can be hinged, and, in other embodiments the connection can be detachable such as a perforated connection. In further embodiments, the connection can be both hinged and detachable.
For embodiments in which the connection is hinged, at least one of the individual packages adjoined by the hinged connection to another of the individual packages can be rotated relative to the other individual package about the hinged connection. In some embodiments, one individual package can be rotated relative to another individual package about a longitudinal axis of the hinged connection that adjoins the individual packages. For example, a first individual package can be rotated, in some embodiments, from about 75 degrees to about 115 degrees, and, in other embodiments, about 90 degrees, relative to a second individual package about the hinged connection that adjoins the first and second individual packages. As a further example, a first individual package can be rotated relative to a second individual package, for example, about the hinged connection that adjoins the first and second individual packages, such that at least a portion of the base of the first package is adjacent to at least a portion of the sidewall of the second package.
In some embodiments, the packaging assembly can further include a secondary exterior package that encases at least a portion of the plurality of individual packages. The secondary exterior package can contribute to bundling and/or securing the plurality of individual packages while also providing increased surface area for presenting promotional information to consumers. The secondary exterior package can be made of any suitable material, including but not limited to plastic, foil, paperboard, or the like. For example, the secondary exterior package can include a shrink-wrap package or a wrap-around package.

It is understood, however, that each individual package of the packaging assembly can be made of the same or different materials from each other without departing from the scope of this invention.
The packaging assemblies of the present invention can be used to package one or more products with a ratio of packaged product volume to occupied space volume that is at least 0.5.
With efficiencies that result in a higher ratio of packaged product volume to occupied space volume as compared to that of conventional multi-unit packs, use of the packaging assemblies of the present invention can lead to lower costs throughout the value chain, such as lower costs for packing, shipping, warehousing, and stocking.
Moreover, the packaging assemblies of the present invention can achieve the aforementioned efficiencies and related cost-savings without sacrificing a capability of providing distinctive aesthetics and/or surface area that is desirable for presenting promotional information to consumers.
The packaging assemblies of the present invention can be used to package any conceivable product. Such products can include, for example, food products or non-food products as well as shelf-stable products or non-shelf stable products. In some embodiments, the packaging assemblies of the present invention can be used to package products, for example, in individual sizes, such as individual serving sizes, individual dosage sizes, or individual application sizes.
Non-limiting examples of food or snack products include yogurt, pudding, applesauce, fruit salad, gelatin products, ice cream, cheese snacks, oatmeal and other breakfast cereal, peanut butter, salsa, hummus, guacamole, other dips or spreads, vegetable salad, tuna salad, soup, pasta, and the like.
Food or snack products are not limited to food or snack products for humans, but also can include food or snack products for non-human animals, such as pet food or pet nutrition or other animal nutrition products.
Non-limiting examples of non-food products include medical products and pharmaceuticals as well as consumer and/or professional products for health care, personal care, beauty care, household care, laundry care, baby care, lawn and garden care, pest control, building and construction, home improvement, automotive care, novelty and entertainment, and the like.
Any conceivable product can be packaged according to a method of the present invention that includes the steps of providing a packaging assembly of the present invention and filling the product into one or more of the plurality of individual packages of the packaging assembly.
In some embodiments, further steps of the aforementioned method can include providing a closure that seals at least one of the openings of the plurality of individual packages, and/or manipulating at least one of the plurality of individual packages to configure the packaging assembly from an unnested configuration into a nested configuration, and/or providing a secondary exterior package that encases at least a portion of the plurality of individual packages.
The packaged product volume and the occupied space volume were determined for each of several exemplary packaging assemblies of the present invention and for each of several commercially available conventional packaging assemblies. The ratio of packaged product volume to occupied space volume was then calculated for each example.
For the several exemplary packaging assemblies of the present invention, the packaged product volume was as specified for the design of the exemplary embodiment. The occupied space volume was determined by measurement of the length, width, and height of the packaging assembly.
For the several exemplary conventional packaging assemblies, the packaged product volume was as reported by the manufacturer. The occupied space volume was determined by measurement of the length, width, and height of the packaging assembly.
Table 1 below shows the results for Examples 1 to 3, which are non-limiting examples of packaging assemblies of the present invention. Example 1 is representative of a packaging assembly including four individual packages of an L-shaped design as depicted in
Tables 2A, 2B, and 2C below show the results for Comparative Examples A to G of several commercially available conventional packaging assemblies.
As shown by Table 1 above, Examples 1 to 3 each had a ratio of packaged product volume to occupied space volume of at least 0.5. In contrast, Comparative Examples A to G each had a ratio of packaged product volume to occupied space volume of less than 0.5.
For 4-package multi-unit packs, Examples 1 and 2 can be compared with Comparative Examples A to F. Within this comparison, Example 2 provided the most efficient packaging configuration with a ratio of packaged product volume to occupied space volume of 0.546, whereas the Comparative Examples had a ratio of packaged product volume to occupied space volume as low as 0.304 (Comparative Example A) and as high as 0.440 (Comparative Example F). Therefore, with respect to packaged product volume relative to occupied space volume, the configuration of Example 2 is about 79% more efficient than the configuration of Comparative Example A and about 24% more efficient than the configuration of Comparative Example F.
For 6-package multi-unit packs, Example 3 can be compared with Comparative Example G. Within this comparison, Example 3 had a ratio of packaged product volume to occupied space volume of 0.563, whereas Comparative Example G had a ratio of packaged product volume to occupied space volume of 0.484. Therefore, with respect to packaged product volume relative to occupied space volume, the configuration of Example 3 is about 16% more efficient than the configuration of Comparative Example G.
Without undue experimentation, those having ordinary skill in the art can utilize the present disclosure including the Description of the Embodiments and the Examples to make packaging assemblies of the present invention that can be more effective with respect to packaged product volume relative to occupied space volume as compared to conventional multi-unit packs.
All documents cited in the Embodiments of the Invention are, in relevant part, incorporated herein by reference; the citation of any document is not to be construed as an admission that it is prior art with respect to the present invention.
While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of the present invention.
