The present invention relates to automated food processing, and more particularly to a package of food products that is configured and formed to enable automation of dispensing of the food products from the package for cooking.
Within the restaurant industry the rising cost of labor, high turnover rates, and shortage of workers has created demand to reduce kitchen staff. As people in the restaurant industry are finding out, the task of fully automating the process of cooking of food is difficult to impossible using the existing packaging that the food products come in. Thus, there is a need for solving the problem of packaging of food products, and also of stacking the food products in a package so that the food products can be easily and properly automated in the environment of a commercial kitchen.
Another challenge in the kitchen is sanitation. Typically, every time a kitchen worker touches raw meat, they are required to wash their hands to prevent spreading of pathogens. Anything that can reduce the risk of contamination is of a great value.
Moreover, with the increased popularity of hamburgers, many machines have been developed to manufacture preformed hamburgers for use in restaurants, fast-food retailing outlets and for sale in supermarkets. Most of these machines are designed to take prechopped meat and form it into meat patties of a predetermined size in diameter and thickness, then stack the patties for further handling. One of the major problems that has been encountered with the operation of the stacks of the meat patties is that dispensing of the raw meat parries from the stacks cannot be easily automated in the environment of a commercial kitchen.
Recent food trends indicate that consumers prefer that hamburgers and the like be made from raw or uncooked patties that are cooked where consumed. Raw or uncooked patties do not have the structural strength provided by frozen patties. Further, raw patties do not have the shelf life of frozen patties. Packaging and systems developed for frozen patties thus may not be suitable for use with raw or uncooked patties.
Therefore, a food product package containing a stack of food products is susceptible to improvements. With this in mind, a need exists to develop a food product package for arranging food products into a stack so that the food products can be safely, easily and conveniently dispensed as needed from the food product package, and so that dispensing of the food products can be easily and properly automated in the environment of a commercial kitchen.
According to a first aspect of the invention, there is provided a food product package for storing and dispensing food products. The food product package comprises a container including a bottom wall and a continuous sidewall extending from the bottom wall and connected to the bottom wall so as to form a storage cavity within the container, a plurality of food products disposed within the storage cavity, a single strip interleaving the food products, and a peelable top film bonded onto the continuous sidewall of the container to thereby to seal the storage cavity and food products within the container. The peelable top film is easily removed from the continuous sidewall of the container so as to open the storage cavity and provide access to the food products disposed within the container.
According to a second aspect, a method of operating a food product package for storing and dispensing food products is disclosed. The method comprises the steps of providing a food product package for storing food products. The package includes a container having a bottom wall and a continuous sidewall extending outwardly from the bottom wall. A plurality of food products are disposed within the container, with a single strip interleaving the food products. A peelable top film is bonded onto the continuous sidewall of the container. The peelable top film is removed and access to the food products provided by pulling the film away from the sidewall of the container to open the container. The food products are dispensed from the container one at a time by pulling the paper strip away from the container.

The container 12 is preferably a rectangular container, so that the major axes of the stacks 161 and 162 extend in parallel through the upper or longer side of container 12. The container 12 includes a bottom wall 23 and a continuous (i.e., endless, uninterrupted, or single) sidewall 24 extending outwardly from the bottom wall 23 and connected to the bottom wall 23. The bottom wall 23 and the continuous sidewall 24 collectively form the storage cavity 14 within the container 12. The storage cavity 14 within the container 12 is thus defined between the bottom wall 23 and the continuous sidewall 24. The continuous sidewall 24 of the container 12 includes a pair of opposite rectangular sidewall sections 25, and a pair of opposite rectangular end wall sections 26. As illustrated in
The continuous sidewall 24 forms a continuous distal edge 27 opposite to the bottom wall 23 as best shown in
The food product package 10 further comprises a flexible peelable (or easy-peel) top film 30 adhesively bonded to the continuous distal edge 27 of the container 12 to seal the storage cavity 14 of the container 12 and encase the food products 18 therein. More specifically, the peelable top film 30 is adhesively bonded to the continuous flange 28 of the container 12. Therefore, the top film 30 is easily peelable from (or detachable from) the continuous flange 28 of the container 12 so as to open the storage cavity 14 and provide access to the food products 18 disposed within the container 12. The peelable top film 30 is bonded to the continuous flange 28 of the container 12 after the food products 18 are placed into the storage cavity 14 of the container 12. While we disclose adhesive bonding of the film 30 to the flange 28, other mechanisms, such as scorelines, lines of weakness, perforations and the like are available for bonding the film 30 to the flange 28 and/or to sidewall 25, and to allow the film 30 to be separated from container 12 and allow access to the interior of container 12. Further, we prefer that the film 30 be manufactured from the same material as used to manufacture container 12.
The peelable top film 30 and the container 12 may be sealed by suitable means to seal the package 10 in an airtight manner. In order to facilitate sealing the peelable top film 30 to the container 12, the flange 28 extends outwardly from the open upper end of the container 12 and the peelable top film 30 may be deposited onto flange 28 for sealing the container 12. If desired, the package 10 may receive an inert atmosphere, such as from nitrogen, carbon dioxide, and argon, in order to maximize the shelf life of the food products 18. Because the package 10 is thus sealed with the food products 18 and the inert gas, where desired, it may be deposited into a corrugated shipping container or the like and transported from the place where the food products 18 are manufactured to the place where they are to be cooked. Thus, the peelable top film 30 enables a user, such as a food preparer, to easily open a portion (or a limited area) of the container 12, defined herein as a pivotable tab 31, from the rest of the sidewall 24. Doing so opens the interior cavity 14 within the container 12 and provides access to the food products 18 disposed within the container 12.
The food products 18 preferably are patties, particularly raw meat or uncooked hamburger patties or sausage patties, packaged into stacks 161 and 162. While we prefer use of the invention with raw or uncooked patties or the like, those skilled in the art will appreciate that it can be used with frozen products. It is well known in the art that such patties 18 are typically relatively flat and usually disc-shaped or square-shaped food products that are to be cooked after being removed from the container 12. The patties 18 are typically made of minced or chopped food, especially meat. Preferably the patties 18 are raw meat hamburger patties 18 made from beef. While raw beef patties are disclosed, those skilled in the art will recognize that patties 18 made from other sorts of meat product, such as chicken and fish, or non-meat food products, such as vegetables, or a mixture thereof, may be utilized. The raw hamburger patties 18 are produced (or formed) by a patty forming machine (not shown).
As described above, the pack 16 preferably includes two stacks 161 and 162 each including a plurality of the food products 18. The stacks 161 and 162 are disposed adjacent to each other along the length L of the container 12, i.e., along the longer sidewall sections 25 of the container 12, as best shown in
The interleaving paper strip 20 has an inner surface 211 in direct contact with the raw hamburger patties 18, and an outer surface 212 not being in contact with any of the raw hamburger patties 18, as best shown in
The pleats of the interleaving paper strip 20 include a plurality of receiving pleats 221 and a plurality of separating pleats 222. Each of the receiving pleats 221 receives and engages one of the food products 18 thereon, while each of the separating pleats 222 does not receive any of the food products 18 and separates two of the adjacent receiving pleats 221. As best shown in
Use of the food product package 10 is straightforward. After the food product package 10 has been closed, the stacks 161 and 162 positioned within the cavity 14 and the package 10 sealed by film 30 adhered to flange 28, the food product package 10 is ready to be opened after being transported to the location where the food products 18 are to be cooked. The package 10 may be tilted, i.e., positioned at an oblique angle relative to the horizontal. Then the package 10 is opened by pulling all or a portion of the peelable top film 30 outwardly off the flange 28 of the container 12. One of the end wall sections 26 of the container 12 is then folded over and under the bottom wall 23 of the container 12. One end of the container 12 is thus opened so that the food products 18 may be removed from the container 12, as best shown in
Pulling on the interleaving paper strip 20 allows individual food products 18 to be removed from the storage cavity 14. As an end of the interleaving paper strip 20 is pulled from package 12, the paper strip 20 begins to be withdrawn from the storage cavity 14, as best shown in
The paper strip 20 may be pulled from the container 12 manually or automatically, such as by a robotic or like mechanical device, so that no human hands need to touch the raw (uncooked) meat of the patties 18. Moreover, optionally, the food product package 10 may be provided with at least one aperture 32 provided to be engaged by a hook at the end use facility to secure the food product package 10 during the step of pulling the paper strip 20 away from the container 12. Accordingly, the food products 18 can be safely, easily and conveniently dispensed as needed from the food product package 10.
Some of the benefits of the novel food product package 10 of the present invention are that only one end of the container 12 needs to be opened. Further, any liquid seeping out of the raw meat products 18, such as blood, stays in the container 12 and kitchen workers do not need to touch any liquid in order to dispose of an empty container 12, thus reducing the risk of spreading pathogens.
The container 112 is preferably a rectangular open top container. The container 112 includes a bottom wall 123 and a continuous (i.e., endless, uninterrupted or single) sidewall 124 extending outwardly from the bottom wall 123 and connected to the bottom wall 123, as best shown in
The container 112, including the bottom wall 123 and the sidewall 124, is a unitary part, i.e., made as a single component. Preferably the container 112 is formed by thermoforming process from a sheet of thermoformable plastic or polymer sheet material, such as a thermoplastic. The package 110 has a top film 113 made from the same or different material as used to make the container 112 and sealed to the container 112 in order to encase the food products 18 therein. The top film 113 and container 112 may be sealed by suitable means, such as sonic welding, thermal welding, or the like in order to seal the package 110 in an airtight manner. In order to facilitate sealing the top film 113 to the container 112, the flange 128 may extend outwardly from the open upper end of container 112 and onto which the top film 113 may be deposited for sealing. Because the package 110 is thus sealed, it may be deposited into a corrugated shipping container or the like and transported from the place where the food products 18 are manufactured to the place where they are to be cooked.
The sidewall 124 of the container 112 is provided with two lines of weakness 130. The container 112 is preferably a plastic sheet, and the weakened lines 130 comprise perforations (i.e., perforation lines or lines of perforations) across the entire sidewall 124. The weakened lines 130 in the sidewall 24 are configured to form a pivotable or pop-out tab 131.
The stack 116 of the food products 18 includes a plurality of the food products 18. The interleaving paper strip 120 has an inner surface 1211 being in direct contact with the raw hamburger patties 18, and an outer surface 1212 not being in contact with any of the raw hamburger patties 18. The interleaving paper strip 120 is pleated, i.e., folded by a certain width while alternating folding directions so as to provide a series of U-shaped pleats. In other words, the pleated paper strip 120 is folded into panels in an accordion-style manner. Each panel of a pair of the pleated paper strip 120 is connected by a common pleat tip (or fold line). Each of the pleat panels has a planar, rectangular face extending between the pleat tips. As shown in
The pleats of the interleaving paper strip 120 include a plurality of receiving pleats 1211 and a plurality of separating pleats 1212. Each of the receiving pleats 1211 receives and holds one of the food products 18 thereon, while each of the separating pleats 1212 does not receive any of the food products 18 and separates two of the adjacent receiving pleats 1211. As best shown in
Use of the food product package 110 is straightforward. After the food product package 110 has been closed due to the stack 116 having been positioned within the cavity 114 and the package 110 sealed, the food product package 110 is ready to be opened after being transported to the location where the food products 18 are to be cooked. The package 110 may be tilted, i.e., positioned at an oblique angle relative to the horizontal, as shown in
The paper strip 120 may be pulled from the container 112 manually or automatically, such as by a robotic or like mechanical device, so that no human hands need to touch raw (uncooked) meat of the patties 18. Accordingly, the food products 18 can be safely, easily and conveniently dispensed as needed from the food product package 110.
Some of the benefits of the novel food product package 110 of the present invention are that only one end of the container 112 needs to be open. Further, any liquid seeping out of the raw meat products 18, such as blood, stays in the container 112 and kitchen workers do not need to touch any liquid in order to dispose of an empty container 112, thus reducing the risk of spreading pathogens.
