The present invention relates to the field of food containment devices for use during cooking, and more particularly to a device for poaching eggs.
Making an acceptable poached egg is a challenge for most people. One contributing factor is that poaching eggs is generally not a daily occurrence with most people. This may result in a user under-cooking or over-cooking an egg. Additionally, there is a tendency with conventional egg poachers for the egg to stick to the cooking 15 surface, yielding unacceptable results.
There are several generally accepted features for an acceptable poached egg. One feature is an egg whose whites have been cooked to set but the yolk is still partially runny. Another feature is that the egg remains intact without losing significant volume into the water. Another feature is an egg that does not stick to the cooking device, since once the egg sticks there is egg loss that occurs and the likelihood for bursting the yolk during removal is higher.
Conventional cooking devices dedicated to poaching eggs are generally bulky and require precious cabinet space for storage. Also, with conventional poaching devices the eggs generally stick to the cooking surface of the device. Some conventional poaching devices have stainless egg shaped holders that submerge in water and have a handle for removal from water. The drawback of these devices is that they have small holes in the bottom area, some of the egg is lost through these holes, plus the egg tends to stick in these holes. Recently devices for the poaching of eggs have been made of silicon. However even in the known silicone versions the holes in the bottom cause egg loss and cause some sticking as egg hardens within these holes. This may increase the cleaning time.
Many of the conventional egg poachers have only one function—to poach eggs—and have no further utility. Also many of the conventional egg poachers are designed to poach multiple eggs simultaneously. Single people, couples with different schedules, dieters, etc. may only want to poach one egg or prepare a single service portion of a food item placed into a cooking device such as a poacher.

Therefore, a need exists for a food containment cooking device with these attributes and functionalities. The food containment cooking device according to embodiments of the invention substantially departs from the conventional concepts and designs of the prior art. It can be appreciated that there exists a continuing need for a new and improved food containment cooking device which can be used commercially. In this regard, the present invention substantially fulfills these objectives.
The foregoing patents and other information reflect the state of the art of which the inventors are aware and are tendered with a view toward discharging the inventors' acknowledged duty of candor in disclosing information that may be pertinent to the patentability of the present invention. It is respectfully stipulated, however, that the foregoing patent and other information do not teach or render obvious, singly or when considered in combination, the inventors' claimed invention.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a device that can contain food, for cooking, storage and other purposes. Generally speaking, the present invention facilitates the poaching of one or more eggs.
In an exemplary embodiment the food containment cooking device is comprised of a one piece flexible bowl like structure with an inside, an outside, a bottom and a wall proceeding from the bottom that is angled outward from the bottom. This structure forms a hollowed out space, or cavity, within the structure into which food items may be placed.
The bottom and the wall are dimensioned to facilitate floating in boiling water when a food item, such as an egg yolk and accompanying egg white, are contained within, e.g., the bottom is curved so the device rocks back and forth in boiling water and the walls are splayed outward to increase volume and stability. In a preferred embodiment the present invention is dimensioned to provide a single serving, e.g. the poaching of one egg.
In a preferred embodiment the material used to form the food containment cooking device is made from highly heat resistant silicon and has a wall thickness of 0.090 inch. In other embodiments the present invention may be made from flexible plastic.
In some embodiments the present invention may be further comprised of one or more tabs that protrude upward from the top of the wall so that a user's fingers may grasp the tabs for removing the food containment cooking device from hot water.
In other embodiments the present invention may be further comprised of a foot or flat portion on the bottom most portion of the bottom surface of the food containment cooking device so that the device may rest in an upright position on a counter or in the microwave.
In other embodiments the present invention may be further comprised of one or more holes at the top of the wall. In embodiments having tabs, the holes may be disposed therein. The holes may be used for the placement of retail tags, for hanging on a hook, to assist in the removal of the device from hot water.
In another embodiment three or more of the present invention may be connected or formed together in an arrangement that maintains the floating feature while allowing the cooking of more than one serving of a food item.
When the present invention is in a substantially upright position it facilitates the holding of food items such as eggs, rice, cake batter, flan, frozen desserts, and the like. This holding may be during cooking, e.g. the present invention is placed in a pot or pan in the oven, on the stove top, microwave. This holding may be during storage in a refrigerator or freezer.
In one embodiment the food containment cooking device made of a flexible material, e.g. high temperature resistant silicon, which is floatable and is formed in one piece to have a curved bottom and a wall that seamlessly encompasses the bottom and protrudes from the bottom upward at an obtuse angle to form a cavity and a wall top edge having a plurality of undulations. In an exemplary embodiment these undulations form three peaks and three valleys. The peaks form tabs that may or may not have a hole formed therein, depending on the embodiment. The thickness of the flexible material is preferably 0.090 inches, but may be less than that thickness, depending on the cooking characteristics desired.
In some embodiments the bottom-most portion of the bottom may be flat to give the device stability when placed on a flat surface.
The present invention departs from the prior art in several features. The ability to float is one. The ability to float without tipping over and spilling held food items during boiling is another. Another feature is the ability of the device to float and have the held food items surrounded by hot water for even, rapid cooking is another. Another feature is the prevention of egg matter being lost into the water. Another feature is that the smoothness of the surface of the device deters an egg sticking to the silicone.
Another feature of the present invention is that the wall thickness of the device may be dimensioned to achieve a 4-minute soft poach or a 6-minute firm poach.
One aspect of the present invention is that it is designed for the boiling of a food item place therein. This is accomplished by placing the device in enough water to permit floating, resulting in heat being distributed evenly around the contained food and resulting in rapid cooking. The poaching of an egg is one use of the device in boiling water. The device can also be used to mimic a double boiler for the melting of chocolate or sugar. The preparation of flan is another food that this device would be particularly helpful in making due to the inherent non-stick features of the material and that the device floats in a water bath.
Another feature of the present invention is that it is also designed for the baking of food items placed therein, as well as the microwaving of food items placed therein. The device may be used to give a unique dome shape to baked or micro-waved foods. Another aspect of the present invention is that it is also designed to be used as a molding vessel. The present invention may be positioned upside down and a melted substance, e.g. melted chocolate or sugar, drizzled over the device. The device with the drizzle may then be placed in the freezer; the device may later be removed from the freezer and the drizzled substance removed from the device by peeling the device away from drizzled substance. The arched substance that remains can then be used as a stylish accent over desserts, e.g., ice cream, pies, miniature pastries, and the like. In the upright position the device may be used as a frozen dessert cup.
Another aspect of the present invention is that it may be manufactured economically.
Another aspect of the present invention is that it may be made from readily available materials.
These and other features and advantages of the present invention will be presented in more detail in the following specification of the invention and the accompanying figures, which illustrate by way of example the principles of the invention.
