The contents of the disclosure related generally to food product packaging. More particularly, but not exclusively, the contents of the disclosure are directed towards food product packaging, including portions which may be modified atmosphere packaged as well as portions which may be non-modified atmosphere packaged.
Modified atmosphere is the practice of modifying the composition of the internal atmosphere of a package (commonly food packages, drugs, etc.) in order to improve the shelf life. The need for this technology for food arises from the short shelf life of food products such as meat, fish, poultry, and dairy in the presence of oxygen. In food, oxygen is readily available for lipid oxidation reactions. Oxygen also helps maintain high respiration rates of fresh produce, which contribute to shortened shelf life. From a microbiological aspect, oxygen encourages the growth of aerobic spoilage microorganisms. Therefore, the reduction of oxygen and its replacement with other gases can reduce or delay oxidation reactions and microbiological spoilage. Oxygen scavengers may also be used to reduce browning due to lipid oxidation by halting the auto-oxidative chemical process.
The modification process generally lowers the amount of oxygen in the headspace of the package. Oxygen can be replaced with nitrogen, a comparatively inert gas, or carbon dioxide.
Problems can arise when food product packaging that includes modified atmosphere also includes additional, separate, pre-packaged food product. This can be in the form of condiments that are packaged with a perishable food product. For example, sandwiches include perishable components, and the modified atmosphere increases the shelf life of the product for shipping, storing, and longer times until use. However, for convenience, condiments (e.g., mayonnaise, ketchup, mustard, butter or margarine, or the like) are added and sold with the sandwich for the consumer to selectively use. The condiments are generally stored in packets, and exposing the packets to the modified atmosphere process can affect the packets, and even cause them to open or burst.
Another way to combine a perishable food product and one or more condiments is to package the products together in a non-modified atmosphere packaging. This could be a bag, a wrap, a foil, film, or the like, which covers or otherwise houses the food product and any condiments. Because this is not fully sealed, the shelf life for the food product is reduced, and there is a higher risk of spoilage and waste.
Therefore, there is a need in the art for an improved food product packaging for perishable food products that allows for the use of modified atmosphere packaging, while also including one or more condiment packets or packages included with the food product that has a high shelf life.

Embodiments described in the present disclosure are directed towards various apparatus, methods, systems of product packaging. The product packaging is considered to hold one or more products, such as food products. For example, the product packaging may hold one or more perishable and/or non-perishable food products in one or more than one compartments or pouches of the product packaging. Still further, it is to be appreciated that, according to any of the embodiments described in the present disclosure, the food packaging may have one or more compartments that are modified atmosphere package compartments. Modified atmosphere involves modifying the composition of an internal atmosphere of a compartment of the package in order to improve the shelf life of a perishable or non-perishable product stored therein. As is known, the methods involved with modified atmosphere packaging involve removing amounts of oxygen in a compartment of a package and replacing with another gas, such as an inert gas, specially chosen gas to maintain the product, or the like. The removal of the oxygen will increase the shelf life of the food products stored therein. In addition, while food products have been disclosed, it should be appreciated that other products could utilize any of the packaging disclosed herein, wherein it is desirable to extend the shelf life of a product stored in one or more of the compartments of the packaging and to mitigate the effects of oxidation on said products stored therein. Therefore, it is to be appreciated that the packaging disclosed according to any of the embodiments described in the present disclosure are not to be limited in any way to a product type that is to be stored in one or any of the compartments, pouches, or portions of the package, including and not limited to the modified atmosphere portion as well as the non-modified atmosphere portion.
Therefore, in order to provide a better understanding of the invention, exemplary embodiments will be disclosed. It should be appreciated that any portion, component, aspect, and/or feature of any of the embodiments disclosed herein are to be interchangeable with any of the other embodiments disclosed. The Figures disclosed are not to be limiting in that any portion of the Figures (both shown and described) can be attributable and useable with any of the other figures to provide a greater number of possible embodiments covered by the present disclosure. Furthermore, while examples will be provided in terms of product type stored in the packaging, it should be appreciated that additional products considered by those skilled in the art and which will benefit from any of the aspects of any of the packaging disclosed in the present disclosure will be considered part of the present disclosure.
The first compartment is formed into a portion of the film 12 and includes an open end 20 and an opposite closed end 22. A first flange 18 provides a peripheral rim around the general open end 20, thus defining a first pouch 16. The size, shape, depth, orientation, and the like of the first compartment 14, including the pouch 16 maybe be determined upon by the shape, number, or other aspects of the product being stored therein. For exemplary purposes, a sandwich 40 is shown being positioned and stored in the first compartment 14 of the package 10 in
As shown in the figures, the product package 10 includes a second compartment 24 which may also be referred to as a header 24. The second compartment 24 is formed in the film 10 to form a second pouch 26. The pouch 26 includes an open end 30, a closed end 32, and a flange 28 generally surrounding the periphery of the open end 30 of the pouch 26. As is noted from the figures, the second pouch 26 of the second compartment 24 has a much less depth compared to the first pouch 16. Again, referring to the example disclosed herein, when a sandwich 40 is included in the first pouch, one or more condiment packets 42 may be stored in the second compartment 24. The condiment packets 42 are generally much smaller than the sandwich 40, and therefore require less room for storage in the product packaging 10. However, if additional condiments were to be included, or if additional food product were to be stored (e.g. additional condiments, additional shape condiments, utensils, cutlery, napkins, packaged beverages, or the like) the second compartment 24 and second pouch 26 could have additional shapes, depth, and/or sizes, and even could substantially match or be bigger than the first compartment 14.
As shown in the figures, the first compartment 14 and second compartment 24 are formed from a common film 12 and thus connected by a hinge 34. The hinge in the figures as shown to be a living hinge 34, such that the living hinge is a portion of the packaging 10 itself. However, it should be appreciated that the first and second compartments 14, 24 need not be formed from a common material or piece of material, and also need not to be connected by film such that they could be separable or separated components that are joined by an independent hinge, as will be understood herein.
Another layer of film in the form of a cover is placed over the open portions 20, 30 of the first and second compartments 14, 24. The cover could take the form of a single piece of film material or could be separable cover portions 36, 38. For the purposes of the present disclosure, whether the cover is a single piece of film or separate pieces of film covering the first and second open portions 20, 30 of the first and second compartments respectively 14, 24, the covers will be referred to by a first cover 36, which is to be understood to cover the first compartment 14 and a second cover 38, which is to be understood to be covering the second compartment 24. The cover material also comprises a film that has a high barrier to moisture and oxygen, but could also comprise other types of films depending on the product in packaging needs. In addition, the cover could be different materials, including, but not limited to, paper, glass, tinfoil or tin, other metals, wrap, or other materials capable of closing the compartments.
The first cover can be connected to the first compartment about the first flange 18. When the food product in the first compartment is perishable, and the first compartment 24 is a modified atmosphere compartment, the first cover 36 can be sealed about the first flange 18 such that it is fully or at least substantially sealed about the periphery of the open portion 20 of the first compartment 14. However, if the compartment is not fully modified atmosphere, the first cover 36 can be attached to the first flange in a non-continuous sealing manner.
The second cover 38 can be connected to the second flange 28 of the second compartment 24 such that there is a plurality of unconnected seals about the periphery of the open end 30 in flange 28 of the second compartment 24. When pre-packaged condiment packets are to be stored in the second compartment 24, there is less of a need for modified atmosphere in the second compartment 24, and thus, the second compartment 24 need not to be fully sealed to prevent or otherwise litigate oxygen exposure therein. However, as will be understood herein, the second compartment 24 could be fully sealed and possibly gas flushed if desired.
As shown in the figures, and in particularly in
Furthermore, once the second and first compartments are folded upon one another, the compartments can be held in place in said configuration until such time that the packaging is to be opened. As shown in
Therefore, as shown in the figures according to the product packaging 10, the following processes and structures are utilized to form an exemplary product packaging 10 and including a food product therein. As disclosed, a flexible film is formed into two compartments of the packaging 10. When a sandwich is to be stored in the packaging 10, the film can comprise a material with a high barrier to moisture and oxygen. A sandwich 40 can be inserted into the first pouch 16 of the first compartment 14, such as according to the arrow 41 in the figures. The pouch 16 of the compartment 14 is sized large enough to allow the sandwich 40 to be housed therein. One or more condiment packets 42 can be placed in the second pouch 26 of the second compartment 24, such as shown by the arrows 43. Another layer of film is placed over the open portions of the first and second compartments the second layer of film can also have a high barrier to moisture and oxygen.
The first compartment 14 which includes the sandwich 40 can then be placed under vacuum to reduce the oxygen per shelf-life purposes. This is the process of modifying the atmosphere in the first compartment 14. Once a predetermined vacuum pressure is reached, a gas mixture can be added back into the package to fully modify the atmosphere in the first compartment 14. Exemplary gases or gas mixtures could be, but are not limited to, be nitrogen, carbon dioxide, a mix of the two, or some other type of inert gas. As the condiments 42 are pre-packaged, the second compartment 14 is isolated from the first compartment 14 such that it is not placed under vacuum to limit the impact of the condiment packages being exposed to the vacuum. This mitigates any structural damage to the condiment packages during the modified atmosphere process for the first compartment 14. Thus, the first compartment 14 is a modified atmosphere compartment, while the second compartment 24 is a non-modified atmosphere compartment.
The two compartments are then sealed, which involves sealing the film cover about the flange 18 and flange 28 of the first and second compartments, respectively. According to exemplary packages, the first compartment is fully sealed about the flange 18. This seal, along with the modified atmosphere from the vacuum and gas flush, provides for improved product self-life compared to simply wrapping the sandwich for including a non-modified atmosphere for a sandwich. The second compartment 24 can comprise small unsealed areas about the periphery of the flange 28 to allow air to escape the second compartment 24, which minimizes the final thickness of the compartment 24. Thus, the thickness of the compartment 24 maybe be dictated by the thickness of the product packaging therein.
After sealing the compartments, the second compartment 24 can be folded towards the first compartment 14, such as shown by the arrow 44 in
Still further, as is shown in
Thus, the package, such as shown in
Furthermore, upon use of the packaging, a user can simply remove or tear the label to unfold the first and second compartments from one another. In addition, the final package can have corners 48 which can be unconnected in a sealing engagement to allow for a peeling of the cover from the first and second compartments, providing access to the product therein. Alternatively, tear notches can be included in the cover, first compartment, and/or second compartment. The tear notches can allow for perforated portions that can be easily opened upon desired entrance to the product packaging. Additional options may include that the sealing engagement of the cover to the first and/or second compartments can be done in a way that allows for reseal. The reseal could be done by adhesive-like material, which can hold the film cover to the flange portions of the packaging, but become easily disengaged therefrom. However, if a user wants to repackage any unused product, the reseal would allow the cover to be reattached to the flange and to hold itself thereto in a closed manner.
Furthermore, as is shown in
In addition, the product packaging 60 includes a modified atmosphere compartment and a non-modified atmosphere compartment. The use of both a modified atmosphere compartment and a non-modified atmosphere compartment allows for perishable product to be stored in the modified atmosphere compartment and pre-packaged or otherwise non-perishable product to be stored in the non-modified atmosphere compartment, which extends the life of the perishable item, while reducing the risk of damage to the pre-packaged or non-perishable product, and thus creating an ideal packaging for mixed perishable and non-perishable product.
Again, the size, shape, and or orientation of the first and/or second compartments 64, 70 of the package 60 can be varied according to the type of product and/or products being stored therein. Furthermore, while a modified and non-modified atmosphere compartment are utilized in the packaging 60, it should be appreciated that both the first and second compartments 64, 70 be modified atmosphere packaging having the same modifications and/or different modifications, depending upon the product stored therein.
In addition, the first compartment 84 includes a first pouch 86 and a first flange 88 about the periphery of the first pouch 86. The first pouch is formed from an opened end 90 and an opposite closed end 92. The distance between the open and closed ends 90, 92 can be variable, such as to accommodate different product stored in house therein. Furthermore, the size, shape, and/or orientation of the open end and flange of the first compartment can be varied according to the use of the packaging 80.
As disclosed, connected via a hinge 104 to the first compartment 84 is a second compartment 94. The second compartment 94 includes a second pouch 96 comprising an open end 100, a closed end 102, and a flange 98 about the periphery of the open end 100. Again, the distance between the open and closed ends can be variable depending upon the product or products stored therein, as well as the size, shape, and/or configuration of the open end and flange, which can be varied according to the desired use of the package and the requirements for the products stored therein. A first and second cover 106, 108 can be positioned over the first and second compartments as a single piece or separate pieces and can be sealed to the first flange 88 and second flange 98 to seal the first compartment 84 separate from the second compartment 94. Similar to that previously disclosed, the first and/or second compartment can be a modified atmosphere compartment in that oxygen be removed and replaced with another gas, such as an inert gas, which can increase the self-life and litigate oxygenation of a product stored therein. Thus, the first compartment 84 can be a modified atmosphere compartment, and the second compartment 94 can be a non-modified atmosphere compartment. Whichever compartment includes a modified atmosphere, said cover can be fully sealed to litigate oxygen from penetrating and entering the modified atmosphere compartment. In addition, the non-modified atmosphere compartment need not to be fully sealed, and can be connected via a plurality of unconnected seals as it is unimportant to prevent or otherwise litigate oxygen from entering the non-modified atmosphere thereof.
Furthermore, a flexible film can be used to comprise the packaging 80 and can include a material that is a barrier to moisture, water, oxygen, or other unwanted materials.
Therefore, product packaging has been shown and described including a plurality of compartments, with the product compartments including modified and non-modified atmosphere therein. The use of modified and/or non-modified packing allows for products of different compositions and different needs to be stored in the different compartments to increase the self-life of the products stored in the packaging. Furthermore, alternatives to that shown and described herein are to be included as part of the disclosure. For example, the film could have a UV barrier to prevent damage caused by any ultra-violet rays. Furthermore, the film could take many opaqueness levels, from being completely clear, to being completely colored such that no color is allowed in or out. This could further improve the self-life of the products stored therein, especially when the product is a perishable product. Additional alternatives may be considered part of the disclosure which are obvious to those skilled in the art, and the invention is not to be limited to the specific examples disclosed herein.
As would be apparent to one of ordinary skill in the art, mechanical, procedural, or other changes may be made without departing from the spirit and scope of the invention. The scope of the invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled. From the foregoing, it can be seen that the invention accomplishes at least all of the stated objectives.
The present disclosure is not to be limited to the particular embodiments described herein. The following claims set forth a number of the embodiments of the present disclosure with greater particularity.
This application claims priority under 35 U.S.C. § 119 to provisional patent application U.S. Ser. No. 62/906,329, filed Sep. 26, 2019.
