This application is a continuation-in-part of U.S. application Ser. No. 14/158,856 filed on Jan. 19, 2014, which in turn claims priority from U.S. Provisional Application Ser. No. 61/851,627 filed on Mar. 12, 2013, the entire contents of both which are incorporated herein by reference.
The present invention relates generally to the storage of food. More particularly, the invention relates to a container for storing soft food.
Storing frozen food requires the use of a sealed container to protect food from freezer burn. Freezer burn occurs when cold, dry air reaches the food's surface, causing water vapor to sublimate out of the food product. Storing food in sealed, individual portions is ideal, but can be inconvenient, time-consuming and space-inefficient if the container does not conform exactly to the food shape.
According to an aspect of the invention, there is provided a container comprising:
At least one or both of the walls and the ridges between the compartments can be tapered to facilitate separation of soft food material into the compartments.
Both the lid and the tray can be made of a flexible material.
The compartments can be defined by the array of walls and the array of ridges can be hexagonal.
The array of walls of the lid can fit tightly into the recess of the tray.
The walls of the lid can be sufficiently rigid to push through soft food material when the lid and the tray are being mated.
The sealing mechanism can include an overlapping lip along the perimeter of the tray for receiving and engaging the perimeter of the lid.
The tray can include a pull tab located at a corner thereof to facilitate partial separation of the tray from the lid.
According to another aspect of the invention, there is provided a container for apportioning and freezing soft food material, comprising:
The tray can include ridges corresponding to the walls of the lid, and wherein the bottom surface of the walls of the lid contact a top surface of the ridges of the tray when the lid and tray are mated.
At least one or both of the walls and the ridges between the compartments can be tapered to facilitate separation of soft food material into the compartments.
Both the lid and the tray can be made of a flexible material.
The compartments defined by the array of walls and the array of ridges can be hexagonal.
The sealing mechanism can include an overlapping lip along the perimeter of the tray for receiving and engaging the perimeter of the lid.
A container for portioning and storing soft food in accordance with an embodiment of the invention is shown in
A sealing mechanism for sealing the lid 20 and the tray 32 about their perimeters is provided by the tray 32 in the form of an overlapping lip 46. The overlapping lip 46 defines a grooved recess dimensioned to receive the perimeter 30 of the lid 20 snugly.
Like the lid 20, the tray 32 and ridges 40 are unitarily made from a flexible plastic.
Now, use of the container will be described with reference to
Pushing of the lid 20 into the tray 32 causes bottom surfaces of the walls 24 to contact with the ridges 40 to seal each compartment 48.
Further, as the perimeter 30 of the lid 20 is pushed down, it slips into the grooved recess of the tray 32 defined by the overlapping lip 46. The overlapping lip 46 and the grooved recess of the tray 32 are dimensioned to provide a second seal between the lid 20 and the tray 32 when the perimeter 30 of the lid 20 is received. This is shown in
These two seals (that is, the ones between the walls 24 and the ridges 40 for each compartment 48 and the one about the perimeters of the lid 20 and the tray 32), serve to protect soft food material stored in the freezer from freezer burn. Even if the seal about the perimeter of the lid 20 and the tray 32 is broken, the seals for each compartment 48 generally remain intact. Each compartment 48 is completely self-enclosed, so that each food portion is doubly protected from freezer burn.
The hexagon shaped compartments 48 defined by the lid 20 and the tray 32 are identical, equilateral and equiangular, which enables equally sized shaping of soft food items.
As previously noted, the container lid 20 and tray 32 are entirely made of a malleable plastic that is soft and elastic throughout, including the walls 24. This enables easy separation of the soft food material from the tray 32 and the lid 20 after freezing the food. The plastic is soft enough to be very flexible, even at freezer temperatures. The geometry of the walls 24 in the hexagonal array make them rigid at each vertex 52. Despite being made of a flexible plastic, these rigid vertices 52 make it possible for the tapered ribs 40 of the tray 32 mating with the corresponding walls 24 of the lid 20 to cut through denser foods such as ground beef.
Once filled with food, the sealed container can be placed in a freezer. When the food portions are fully frozen, the container may easily be opened using a pull tab 56 at the corner of the tray 32. The soft plastic material flexes to allow easy removal of food portions, fresh or frozen. By peeling apart the lid 20 and the bottom tray 4 to partially separate them, as many pieces as required may be removed from the container without fully opening it. If the container is not fully opened, at least some of the compartments 48 opposite to the side where the container is being opened can remain sealed, thereby preventing exposure to ambient air of the undispensed food within and minimizing freezer burn. These remaining food portions may be returned to the freezer, each sealed, stored, and protected within their individual storage compartments 48.
The resulting hexagonally shaped food portions may then be transferred to be cooked, typically forming a rounded shape when heated, as in the case of cookies or ground meats.
While the compartments defined by the walls, ridges, and the recess in the above embodiment are described as being hexagonal, those skilled in the art will appreciate that compartments of other shapes can be used. For example, triangular or rectangular compartments can be employed in some cases. Adjustment of the thickness of the walls or the rigidity of the material may be desired to accommodate for the inherent differences in structural strength.
Other types of sealing mechanisms for retaining the lid in sealed relationship with the tray can be employed. For example, hinged clips or a rigid or flexible clamp can be used.
One or both of the lid and the tray can be constructed from other materials. While it may be preferred that the materials be flexible, it can be desirable in some cases to construct the lid and/or tray so that they are articulated; that is, they have flexible or hinged portions.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention.
