Tray with a plurality of cavities for the freezing and storage of foodstuffs in specific volumes, and methods to stabilize said tray
A tray for the storage and preservation of foods and liquids that has a plurality of cavities, the volumes of which are common units of measure in cooking recipes and for calorie counting. A lid is also described which fits tightly onto the top of the tray to act as a sealing piece to help in the extended preservation of the contents of the tray. The lid also acts as a stabilizing element. When the tray is made from a flexible material, design features that create an internal support structure are described. There is also an optional external support structure that can be manufactured and attached to the tray to add dimensional stability, when necessary.
The invention relates to the field of food storage and freezing. More specifically, the invention comprises a tray with a plurality of cavities of specific volumes useful for cooking and calculation of caloric value, a lid, and possibly an external support structure, which is an improvement over current methods of storing and freezing foods and liquids.
BACKGROUND OF THE INVENTIONThere are vast numbers of products available for the containment, transportation and storage of liquid and semi-liquid foodstuffs. There are also many products that that have been created for the freezing of foods, in various forms of trays. When freezing large quantities of foods and liquids, it is common practice for any number of containers to be used. These can include products specifically designed to freeze liquid, but not foodstuffs (such as ice trays), or products that are designed to store food in general within a single cavity (such as Tupperware or various sizes and types of bowls or other containers).
There are currently no food storage or freezing containers that have a plurality of cavities, where the cavities are of specific volumes, where the tray is designed to store or freeze foodstuffs in portions that are useful for cooking recipes.
In the current state of the art, ice trays are designed to freeze water in a variety of sizes and shapes, in a plurality of cavities, which are convenient for use in cooling a second body of fluid in a glass or other container. There is currently no ice tray available specifically designed to store or freeze foods or fluids for use in cooking. There are also no ice trays available that create a frozen product that is of a measured volume designed to be useful in cooking or in the calculation of caloric value. Ice trays that are currently available are made from either a hard plastic, or from silicone rubber. The majority of ice trays made from hard plastic do not come with a lid, and none of the currently available trays made from silicone have lids. Silicone ice trays are also designed with vertical sides that make it difficult to remove the resulting frozen product from the tray.
General food storage containers are designed to store larger portions of food or liquid, in a single cavity, that can be placed in the refrigerator or freezer. Containers of this type are designed to hold individual volumes that are larger than those held in the individual cavities of ice trays. When these containers are used to freeze and store liquids or food, their product is very large and creates an all-or-nothing scenario for the un-freezing of the liquid or food in question. The volume represented is rarely useful in a situation where the liquid or food will be used in the creation of a recipe, or in portion control, creating an excess, and commonly wasted, amount of food or liquid.
None of the currently patented or available products for the storage or freezing of foods and liquids are designed to hold specific volumes of substances in common standardized units of measure, neither imperial nor metric, that are useful in the preparation of food recipes, for a facilitated calculation of caloric value, or for meal portion control.
The current patent application pertains to an invention that is used for the containment, transportation and storage of liquids and other non-solid foodstuffs in portions of specific volumes. This allows for useful, specific volumes of liquid or food to be stored and/or frozen for use at a later date. These volumes are also useful in calculation of caloric values, and for easy management of portion size.
The invention consists of two main pieces:
1. A tray made from a flexible rubber or hard plastic
2. A lid made from a rigid material
The invention can also include an exterior structure that is attached to the tray to increase the dimensional stability, possibly necessitated by the flexible nature of the material from which the tray is made, and/or if the overall dimensions of the tray render the tray dimensional unstable when handled.
The figures in the present disclosure feature a tray with a plurality of cavities. The number of cavities present in the figures is four, and only serves as an exemplar of one possible embodiment covered by this patent. The number of cavities proposed in the current patent (a plurality) is intended to be more than one, and is therefore not limited to four. The present embodiment is also depicted as having horizontal dimensions that are different from each other (forming a rectangular tray). Different embodiments of the current invention can also have horizontal dimensions that are the same.
Claims
1. A storage device for preserving and freezing foods and liquids: a tray with a plurality of cavities; a lid that fits on top of the tray; an optional external support structure into which the tray is placed.
2. The tray as defined in claim 1 wherein said tray is manufactured from any of the family of silicones that are considered food-safe.
3. The tray as defined in claim 1 wherein said tray is manufactured from a material that is considered food-safe, such as PET, PETG, or polycarbonate, or other food-safe plastics.
4. The tray as defined in claim 1 wherein said cavities are manufactured to hold specific volumes of foods or liquids in either imperial or metric units of measure; when imperial these volumes include two-cups, one-cup, one-half-cup, one-quarter cup, one-third cup; when metric these volumes include 500-millileters, 250 milliliters, 200-milliliters, 100-milliliters or 50 milliliters, or other volumes used when cooking recipes or for the calculation of caloric content.
5. The volumes of the cavities as defined in claim 4 wherein said cavities are manufactured to hold specific volumes of foods or liquid which can be used in the preparation of cooking recipes commonly found in cookbooks, family recipe collections, or on the Internet.
6. The volumes of the tray in claim 4 wherein said cavities are manufactured to hold specific volumes of foods or liquid which can be used for the calculation of caloric content of said foods or liquid.
7. The cavities as described in claim 1 wherein said cavities have an upper opening that is dimensionally larger than the bottom of the cavity, creating sides that are angled inward toward the bottom of the tray. These sides make the removal of any frozen substance contained in the cavities easier than if the sides were straight.
8. The tray as described in claim 1 wherein said tray is made from silicone as described in claim 2
9. The tray as described in claim 8 wherein said tray has a plurality of cavities separated by walls which are either created by the abutting walls of two adjacent cavities or the outer walls of the tray.
10. The walls as described in claim 9 wherein said walls are created from abutting walls of two adjacent cavities, said walls are thinner at the top and thicker at the bottom due to the difference in the dimensions between the opening and the bottom surface of the cavity as described in claim 7. This creates an angled support structure in the body of the tray when multiple cavities are present in the tray. These support structures extend the full length and width of the tray when multiple cavities are present.
11. The tray as described in claim 1 wherein said tray has a top lip or rim that is present around the top circumference of the tray and extends below the top opening of the cavities of the tray
12. The lip as described in claim 11 wherein said lip intersects and connects to the support structure as described in claim 10 due to the lip extending below the cavity opening creating an internal support structure (FIG. 19), which creates dimensional stability for the tray when it is being handled or transported
13. The lid as defined in claim 1 wherein said lid is manufactured from: a) a food-safe plastic, such as PET, PETG, or polycarbonate, or other food-safe plastics; b)a food-safe metal or ceramic with thermal conductivity characteristics that aids in the freezing of the contents of the tray; c) or a combination of a) and b).
14. The lid as defined in claim 1 wherein said lid fits tightly on top of the tray described in claim 1 helping the substances stored or frozen in said tray to stay fresh and delay the adverse affects of freezing and storing on contents of the tray.
15. The lid as defined in claim 13 wherein the lid creates dimensional stability for the tray, especially when the tray is made from a flexible material such as silicone.
16. The external support structure defined in claim 1 wherein said external support structure is manufactured separately from the tray as described in claim 1 and can be attached to the external sides and/or bottom of the tray.
17. The external structure defined in claim 16 wherein said external structure aids in the stability of a full tray when it is transported or handled, especially when the tray is of a larger size or made from a more flexible material such as silicone.
18. The external structure as defined in claim 17 wherein the structure, in one embodiment, is formed by one piece that encompasses the outer circumference of the tray and one or more pieces that run along underneath the tray and are attached to the first piece at either end of the tray, lengthwise, widthwise or both.
19. The external structure defined in claim 30 wherein said external structure is manufactured from: a) a food-safe plastic, such as PET, PETG, or polycarbonate, or other food-safe plastics; b)a food-safe metal or ceramic with thermal conductivity characteristics that aids in the freezing of the contents of the tray; c) or a combination of a) and b).
