The present disclosure relates to food containers and, more specifically, to a microwave compatible container and associated method of use for heating food.
The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
Microwave ovens have been in household use for decades. Microwave ovens generally use radio waves at approximately 2.45 gigahertz (GHz), where the waves have wavelengths of approximately micron lengths (thus, “microwaves”), to agitate water molecules in food. As the water molecules are excited by the radio waves, the water begins to vibrate and generate heat. Because the water molecules in the food are vibrating and generating heat at the same time, food may cook in microwave ovens faster than food cooked in a conventional oven where heat slowly travels from the outside surface of the food inward. Additionally, many consumers use microwave ovens for reheating previously cooked food. For many foods, microwave reheating over-excites the water molecules and dries out the food. Examples of food that may not reheat well are dough-based foods such as breads, pizza, sandwiches, hamburgers or cheeseburgers in a bun, and french fried potatoes.
In various embodiments of the present disclosure, a method of heating food with a microwave is disclosed. The method can include providing a microwave compatible container for heating food. The container can comprise a bottom wall, outer and inner walls extending from the bottom wall, and a removable top. The outer wall can have an exterior surface and an interior surface. The inner wall can have an exterior facing surface and an interior facing surface. The interior facing surface of the inner wall and the bottom wall can define an inner compartment of the container. Further, the exterior facing surface of the inner wall, the interior surface of the outer wall, and the bottom wall can define an outer compartment that surrounds the inner compartment. The removable top can be sealingly engaged with the outer wall and the inner wall in a closed configuration such that the inner compartment is sealed from the outer compartment.
The method can also include placing food within the inner compartment and at least partially filling the outer compartment with water or another liquid. The method can additionally include sealingly engaging the removable top with the outer wall and the inner wall in the closed configuration such that the food and the water or other liquid are sealed within the inner compartment and outer compartment, respectively. A microwave can be utilized to heat the food when the food and the water or other liquid are sealed within the inner compartment and outer compartment, respectively.
In other aspects, the present disclosure relates to a microwave compatible container for heating food. The container can comprise a bottom wall, outer and inner walls extending from the bottom wall, and a removable top. The outer wall can have an exterior surface and an interior surface. The inner wall can have an exterior facing surface and an interior facing surface. The interior facing surface of the inner wall and the bottom wall can define an inner compartment of the container. Further, the exterior facing surface of the inner wall, the interior surface of the outer wall, and the bottom wall can define an outer compartment that surrounds the inner compartment. The removable top can be sealingly engaged with the outer wall and the inner wall in a closed configuration such that the inner compartment is sealed from the outer compartment.
In additional or alternative aspects, the present disclosure relates to a microwave compatible container for heating food. The container can comprise a bottom wall, outer and inner walls extending from the bottom wall, and a removable top. The outer wall can have an exterior surface and an interior surface. The inner wall can have an exterior facing surface and an interior facing surface. The interior facing surface of the inner wall and the bottom wall can define an inner compartment of the container. Further, the exterior facing surface of the inner wall, the interior surface of the outer wall, and the bottom wall can define an outer compartment that surrounds the inner compartment. The removable top can be sealingly engaged with the outer wall in a closed configuration such that the inner and outer compartments are sealed, e.g. from the ambient environment.
Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.
The present disclosure will become more fully understood from the detailed description and the accompanying drawings, wherein:
As previously discussed, microwave ovens are frequently used for cooking and reheating food. There are many microwave cooking gadgets available on the market for consumers. For example only, there are specialty microwave pasta cookers, bacon trays or racks, and even microwave egg containers. The microwaves that agitate the water molecules may pass through many plastics, glass, and ceramics without agitating any of the molecules of such materials. As such, plastic and glass containers may not heat up when used in microwave ovens. Metals reflect microwaves and, therefore, metal containers may not be safe to use in microwave ovens. For this reason, most microwave cooking gadgets are made of a plastic, glass, and/or ceramic material, which can be identified as “microwave safe.”
While utilizing a microwave oven is a quick and convenient way to cook and reheat food, there may also be drawbacks associated with utilizing a microwave to cook/reheat certain foods. For example only, microwave reheating may over-excite the water molecules and dry out certain foods, such as breads, pizza, and sandwiches. In other foods, microwave reheating may cause the food to become soggy. It would be desirable to provide a microwave cooking container that addresses some or all of these drawbacks and provides for improved cooking or reheating of food when utilizing a microwave oven.
Accordingly, a microwave compatible cooking/reheating container and method of use are presented. The container includes two compartments: an inner compartment and an outer compartment. Food is placed within the inner compartment and water or another liquid is placed in the outer compartment. A removable top is secured to the container. The removable top may seal the container from the ambient environment. Further, in some aspects, the removable top may seal the inner compartment from the outer compartment such that the food compartment is not in communication with the water/liquid compartment. In this manner, the steam, moisture, etc. generated by heating the water/liquid will not enter into the food compartment during reheating. In other aspects, the removable top may seal the container from the ambient environment but not seal the inner compartment from the outer compartment. In this manner, the steam, moisture, etc. generated by heating the water/liquid will be free to enter the food compartment during reheating.
The microwave container may additionally or alternatively include a raised surface in the inner (food) compartment such that food placed within the inner compartment will not rest directly on the bottom wall of the container. In this manner, air may circulate under the food during the heating process, which may provide a more even distribution of heat to the food. Additionally, water or another liquid may be placed in the inner compartment as well as the outer compartment such that moisture, steam, etc. from the liquid in the inner compartment may contact the food. The raised surface can be a tray or a plurality of projections extending upwardly from the bottom wall of the container.
By placing water or another liquid in the outer compartment and food within the inner compartment, the disclosed microwave container permits for an improved method of cooking and reheating food. For example only, the water in the outer compartment may absorb some of the microwave energy generated by the microwave and, thereby, avoid the over-excitement of the water molecules in the food. This permits a more even cooking or reheating of the food while also inhibiting the drying out of the food. Further advantages of the container may be readily apparent.
Referring now to
The container 100 can include a bottom wall 120, an outer wall 140, an inner wall 160, and a removable top 180. The outer wall 140 can extend upwardly from the bottom wall 120 and have an exterior surface 142 and an interior surface 144. The exterior surface 142 can comprise the outside surface of the container 100, and the interior surface 144 can comprise the primary interior surface of the container 100. Similarly, the inner wall 160 can have an exterior facing surface 162 and an interior facing surface 164.
The bottom wall 120, outer wall 40, and the inner wall 160 can cooperate to define at least two chambers or compartments of the container 100. In the illustrated example, the interior facing surface 164 of the inner wall 160 and the bottom wall 120 cooperate to define an inner compartment 170. Further, the exterior facing surface 162 of the inner wall 160, the interior surface 144 of the outer wall 140, and the bottom wall 120 cooperate to define an outer compartment 175 that surrounds the inner compartment 170.
In the illustrated example of
With further reference to
In some implementations, the container 100 can further include a raised surface 190 that is arranged the bottom wall 120 within the inner compartment 170. In the illustrated example of
It should be appreciated that, although the raised surface 190 is illustrated as the tray 192, the raised surface 190 may take other forms. For example only, the raised surface 190 may comprise a plurality of projections (not shown) extending upwardly from the bottom wall 120. Food to be heated in the microwave can be placed on the raised surface 190/plurality of projections and air can flow both above and below the food during heating. The plurality of projections can have various shapes, such as a pyramidal shape, a hemispherical shape, a columnar shape, a line, a stripe, or a combination thereof.
In addition to providing for air circulation below the food to be heated, the raised surface 190 may also permit water or another liquid to be placed in the inner compartment 170 without contacting the food to be heated. For example only, a user may partially fill the inner compartment 170 with water or another liquid below a level of the raised surface 190. In this manner, the moisture, steam, etc. released by the water/liquid during heating can rise and come into contact with the bottom of the food, e.g., to steam the food during heating.
