A preferred embodiment of a packaging device comprises a lid that is slidably engaged to a tray having a compartment for holding processed sliced meats. The packaging device further includes a manually releasable lid lock for re-sealing the packaging device after use. Also provided in a preferred embodiment of the packaging device is a support foot for stabilizing the package during stacking or vertical display.
This invention relates generally to the field of packaging devices. More specifically, this invention involves a packaging device for sliced deli meats, fish, cheeses and other related foods. Even more particularly, this invention relates to an improved packaging device which incorporates a lid that is slidably engaged to a tray.
BACKGROUND OF THE INVENTIONConventional packaging for sliced deli meat, smoked fish, cheeses and other processed foods has been in existence for many years. Packaging for these foods has evolved over the years with the goal of providing convenience to consumers, as well as increasing the shelf life of food without sacrificing freshness and taste. Indeed, retail deli-meat packaging continues to grow more important for companies as consumers, who are already accustomed to being exposed to innovative designs in other product areas, look for innovation in packaging that keep foods fresher for longer periods of time and which are easy to open and close.
Generally, current forms of packaging for sliced deli meats and related foods either cannot be resealed or have limited interior accessibility. Vacuum-sealed plastic packaging, for example, has been and continues to be, utilized to keep its contents fresh for a longer period of time. However, vacuum-sealed packages which use relatively thick plastics are often difficult to open without the assistance of a sharp edge. Furthermore, after opening, many vacuum-sealed packages do not lend themselves to being re-sealed, thereby reducing the shelf life of contents if not consumed in a single sitting. Current forms of tray-based deli-meat packaging suffer from similar shortcomings in that once a package is opened, it typically cannot be re-sealed.
To address the foregoing concern, re-sealable plastic packaging with press-to-close zippers was introduced to consumers, eliminating the need for consumers to place contents of an opened vacuum-sealed package in an entirely new container. While a re-sealable package does not eliminate the possibility of contaminants being introduced to the food, it has been utilized to provide consumers with a means to conveniently store the food without having to transfer uneaten portions to a separate bag or container.
Since the introduction of the re-sealable package, other features have been incorporated into packaging as well. For example, one of the latest advancements in packaging involves the use of a sliding zipper which provides a reliable means to open and close a package containing deli meat or other perishables. This has been considered by many to be superior to conventional press-to-close zippers that have been widely available to consumers for years now.
Despite the convenience and other advantages offered by these packaging products, there still remain some inherent disadvantages in current re-sealable deli-meat packaging. in particular, accessibility into the interior of deli-meat packaging is limited, essentially requiring a consumer to reach through a narrow portal and into a narrow space inside the package to retrieve its contents. This is especially unappealing when juices from the meat are present in the package, which can result in a brief (but potentially strong) feeling of revulsion when the juices make contact with the hands of a user.
Another disadvantage of current forms of deli-meat packaging is that the exterior surface conforms to its contents, resulting in a non-uniform surface on which branding, content information, nutritional information and other visual indicia appear. In extreme situations, some information is entirely obscured because select areas of the packaging, whether at the edges or in the middle, are “sucked in” or “folded over” as a result of the manufacturing or sealing process.
SUMMARY OF THE INVENTIONIn view of the deficiencies and drawbacks in the prior art, it is, it is a primary object of the present invention to provide an improved packaging device with a sliding lid that is both re-sealable and provides increased accessibility to the contents thereof.
Another object of the present invention is to provide an improved packaging device with a sliding lid that has a uniform surface on which branding, content information, nutritional information and other visual indicia is clearly displayed for consumers.
A further object of the present invention to provide an improved packaging device packaging device for sliced deli-meats, having a sliding lid engaged to a tray that is easier and more convenient to use as compared to other packaging products.
Another object of the present invention is to create a low-volume product-package combination, thus maximizing space on display shelves and showcases.
Additional objectives will be apparent from the description of the invention that follows.
In summary, there is provided in a preferred embodiment of the present invention an improved packaging device comprising a plastic lid that is slidably engaged to a tray having a compartment for sliced deli meat. The packaging device further includes a manually releasable lid lock for re-sealing the package after use. A preferred embodiment of the improved packaging device is an aesthetically pleasing, value added, hermetically sealed, hanging peg-board product that is easy to open and close as needed. By utilizing the product, deli-meat and the like can be kept safely under refrigeration for an extended period of time after initial opening by utilizing the accompanying sliding lid.
The above-described and other advantages and features of the present disclosure will be appreciated and understood by those skilled in the art from the following detailed description and drawings of which
With reference to
The packaging device 10 further includes a clear plastic lid or cover 30 that is sized and adapted to complement the tray 12. The lid 30 is positioned in sliding engagement with the tray 12, providing a container that is easy to repeatedly open and close as needed, until emptied. The lid 30 and tray 12 are constructed to allow the lid 30 to slide relative to the tray 12 a sufficient distance to expose the tray 12 and allow full access to the contents of the package 10 without contacting the lid 30 during the act of removal of the contents. The lid 30 comprises a section with a uniform surface 32 on which branding, content information, nutritional information and other visual indicia may be clearly displayed for consumers. The lid 30 has a sufficient thickness and rigidity to prevent it from becoming unintentionally deformed, thus providing an aesthetically pleasing display at all times for consumers to view when shopping.
In the preferred embodiment, the lid 30 is incorporated as part of the packaging device 10 subsequent to the contents of the package being sealed (by vacuum sealing or otherwise) with an interior film seal S, as shown in
As shown most clearly in
As also shown in
The tray 12 and lid 30 together produce a lid lock 50 that keeps the lid 30 from sliding along the tray 12 and uncovering its contents. The lid lock 50 is formed from creating one or more mating protrusions or depressions 52, 54 in the tray 12 and lid 30 at the top or forward ends thereof. The mating protrusions 52, 54 serve as a lid lock 50 to maintain the packaging device 10 in a closed position. This feature is particularly advantageous in keeping the package closed after the interior seal film (shown in
Aside from the upward protrusion(s) 52 in the tray 12 that produce a lid lock 50, the tray 12 further comprises a raised section or ledge 56 around its entire perimeter. The outer section of the ledge 56 tapers off to form sloped edge 58. Due to the increased height of the tray 12 caused by the ledge, the lid 30 must be formed to accommodate this increase in height of the tray 12. The contact between the lid 30 and ledge 56 helps form a better and more consistent seal after the initial sealing material is removed in order to keep the contents of the compartment 14 fresher longer. The sloped edge 58 helps provide a surface that is conducive to sliding along the channel 34 of the lid 30. While the ledge 56 of the preferred embodiment proceeds around the entire perimeter of the tray 12, it should be understood that the ledge may extend around less than the entire perimeter while still keeping within the spirit and scope of the invention.
With reference to
The packaging device 110 further includes a clear plastic lid or cover 130 that is sized and adapted to complement the tray 112. The lid 130 is positioned in sliding engagement with the tray 112, providing a container that is easy to repeatedly open and close as needed, until emptied. The lid 130 comprises a uniform surface 32 on which branding, content information, nutritional information and other visual indicia may be clearly displayed for consumers.
In the preferred embodiment, the lid 130 is incorporated as part of the packaging device 110 subsequent to the contents of the package being sealed (by vacuum sealing or otherwise) with an interior film seal, as shown in
As shown most clearly in
As shown in
As shown in
While the preferred embodiment has protrusions on the lid and depressions located on the tray, it should be understood that the protrusions may be positioned on the tray with depressions located on the lid. Likewise, it should be understood that the lid lock mechanism may be altered to further limit the range within which the lid can slide relative to the tray. It is also possible for a lid to be incorporated into the packaging device without a lid lock.
In connection with the preferred embodiments herein, the contents of the packaging device are preferably vacuum sealed and have been run through a high pressure processing system to remove bacteria and/or other contaminants. Aside from the lid, a thin interior seal film is applied to keep the food fresh and free from contaminants. After the seal film is peeled off or otherwise removed, the lid remains available to re-seal the package and keep contents fresher, longer.
While the interior seal film is typically discarded after the package is opened, another embodiment of the packaging device may incorporate an interior seal film that remains attached to the tray and serves to re-create a fully airtight seal. In such an embodiment, the interior seal film is “pinched” between the tray and the lid after as the lid slides into the closed position. Such a feature may be incorporated with or without the lid lock as well.
The tray 12, 112 of the packaging device 10, 110 is preferably formed of a recyclable mono-layer polyethylene terephthalate (PET) material that is commonly utilized in the production of food and beverage containers. The tray 12, 112 is thermo-formed into the required shape and size cavity using a convention horizontal form, fill and seal packaging machine (HFFS). After the tray is formed using the HFFS, sliced deli-meat (or any appropriate product) is loaded into the empty trays in the HFFS's loading area. The trays and meat are then transported via gripper chains into the seal/evacuation station. After the appropriate sealing process has taken place and the tray has been discharged, the tray and meat (or other food) package is run through a high pressure processing (HPP) system. Thereafter, the sliding lid 30, 130 is manually applied to the package. With additional equipment, it is also possible to have the lid automatically applied as part of the production process, Much like the corresponding tray, the lid of the packaging device is preferably formed of a recyclable mono-layer PET material. The lid is thermo-formed into the required shape and size cavity using a HFFS as well.
