PACKAGES FOR AND METHODS OF PACKAGING FOOD PRODUCTS
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Patent Application No. 15/002504.
filed January 21. 2016.
In general. the invention relates to a packaging device for food products.
More pm-ticularly. the invention relates to expandable packages for food products.
BACKGROUND OF THE INVENTION
The art of food packaging is well developed. For example, within the art of dough packaging there are multiple ways of packaging proofed and un-proofed dough.
Proofing dough is know in the art to mean allowing dough containing a leavening agent to rise for the proper amount of time such that the dough reaches a desired volume.
U.S. Pat. No. 6.635.291, Perry.. entitled Leavened Dough or Batter Packaging System discloses a package for leavened dough designed to hold a desired internal equilibrium pressure.
U.S. Pat. No. 6.733.803. Vidkjaer, entitled Dough Containing. Valved Package discloses a package for dough that does not have to he proofed having a one-way venting valve to allow gas to escape from the package.
U.S. Pat. No. 1.861,124. Lorber. entitled Biscuit Package discloses a package for R.,Joked biscuits having a telescoping cover which provides space for the risen dough. Further.
Lorher's design has a channel l'br receiving the telescoping cover and requires separation of a number of dough cakes with interposed circular disks which may complicate producing such a design.
Pat. No. 6,240.839. Amato. entitled Device for Proofing Dough discloses a mechanical device having an electronic alarm or electronic visual indicator assembly for signaling when the dough reaches a specific volume.
Most of the prior art mentioned above does not provide for packaging of un-proofed dough products. Known packages that do provide for packaging of un-prooled dough do not indicate when the dough is ready or proofed. Letting dough proof for the proper amount of time is an art. The time it takes dough to proof is dependent upon many variables such as temperature, humidity, dough ingredients and the strain of yeast used in the dough. Thus, the proof time of dough is often misjudged and the dough is used either prematurely or after it has proofed. Furthermore, known proofing approaches for dough generally require the consumer to purchase a separate device, apart from the dough packaging. to determine when the dough is ready. Such known prior art devices that indicate when dough is ready tend to be expensive and more suited for commercial operations.
Furthermore, recent health concerns around the food packaging of popcorn in microwave ready packages have created a need for an expandable food package for popcorn that is chemical free. made from virgin fiber paperboard. recyclable and compostable.
St .MMARY OF THE INVENTION
Embodiments of the invention relate to packages for food products. More specifically.
embodiments of the invention relate to inexpensive expandable packages in which dough can be sold and in which dough can be proofed to the correct/desired volume by consumers.
In one embodiment of the present invention the package has two portions, a first portion and a second portion. The first portion has a first closed end, at least one first side wall surrounding the first closed end, and a first open end opposite the first closed end. The second portion has a second closed end, at least one second side wall surrounding said second closed end. and a second open end opposite the second closed end. The first portion and second portion are movably connected at their respective open ends, such that an enclosed void of variable olume is created between the first closed end and the second closed end.
Additionally, at least one indicator is placed in communication with the package such that when the package is exi),Inded to a desired inner volume the indicator is activated. Activation of the indicator may produce, for example. a visual indication, an audio indication, an indication recognizable by touch. or any combination thereof.
The packages of the present invention provide for an inexpensive and easily manufacturable package for food products. Furthermore, the packages of the present invention provide for a dough package in which dough can be manufactured. sold. and proofed to the correct or desired volume without the need for separate more expensive devices.
In a further illustrative embodiment of the present invention, the packages of the present ention provide for a use as a food package for popcorn allowing for the popping of corn to a desired volume without the need for separate more expensive device. According to the in\ ention, the instant food package can further be used as a serving container for the expanded food product.
