Definitions
- the present invention relates, generally, to food containers used in storing and displaying heated foods, as well as in serving foods from these containers.
- Such containers may be used, for example, by a retailer to sell pre-prepared food items, such as roasted chickens, and may additionally be re-used by the consumer subsequent to the original sale.
- the food container of the present invention is an improvement over the conventional prepared food containers in that it features, among other things, an improved handle, where the heat from the container is not fully felt by the person holding the container, while still providing an advanced sealing mechanism to prevent the escape of the contents of the container.
- Food containers similar to, though distinguishable from, the present invention are often used in scenarios where a retailer will prepare and sell a food item that is ready to eat.
- a problem recognized with respect to conventional food containers arises when the food is prepared and people subsequently purchase food contained in the containers. Oftentimes the containers may become warm, as a result of the temperature of the prepared food contained therein. This warmth may be of such a degree so as to cause at least some discomfort to a person who picks up, holds, moves or otherwise comes into contact with that container.
- Another problem recognized with respect to conventional food containers relates to the awkward shapes of and imbalanced food loads within food containers, in addition to the aforementioned warmth-related discomfort.
- Yet another problem recognized with respect to conventional food containers relates to the desire by the manufacturers of such containers to be able to create each piece, those being the base and the lid, in a single plane cut, while still maintaining certain beneficial features. It is desirable for the manufacturer of a food container, including those of the present invention, to be able to separate the formed lid or base from the sheet of raw material from which the lid or base has been pressed in a single two-dimensional cut, thereby reducing costs, such as the costs of creating more expensive manufacturing equipment. Thus such a single plane cut is a desirable feature.

The food container of the present invention is an improvement over the conventional prepared food containers in that it features, among other things, an improved handle, where the heat from the container is not fully felt by the person holding the container, while still providing an advanced sealing mechanism to prevent the escape of the contents of the container.
- Food containers similar to, though distinguishable from, the present invention are often used in scenarios where a retailer will prepare and sell a food item that is ready to eat.
- A problem recognized with respect to conventional food containers arises when the food is prepared and people subsequently purchase food contained in the containers. Oftentimes the containers may become warm, as a result of the temperature of the prepared food contained therein. This warmth may be of such a degree so as to cause at least some discomfort to a person who picks up, holds, moves or otherwise comes into contact with that container.
- Another problem recognized with respect to conventional food containers relates to the awkward shapes of and imbalanced food loads within food containers, in addition to the aforementioned warmth-related discomfort.
- Yet another problem recognized with respect to conventional food containers relates to the desire by the manufacturers of such containers to be able to create each piece, those being the base and the lid, in a single plane cut, while still maintaining certain beneficial features. It is desirable for the manufacturer of a food container, including those of the present invention, to be able to separate the formed lid or base from the sheet of raw material from which the lid or base has been pressed in a single two-dimensional cut, thereby reducing costs, such as the costs of creating more expensive manufacturing equipment. Thus such a single plane cut is a desirable feature.
- The aforementioned problems, as well as others recognizable to those of ordinary skill in the art, are addressed by the present invention.
- The present invention is a food container comprising a base and a lid. The lid comprises an upper lid surface, a lid sidewall and a lid lip. The base comprises a lower base surface, a base sidewall and a base lip. The lid lip and the base lip both comprise an interlocking arrangement such that the lid may be secured to the base, and in being so secured provides an inner seal and an outer seal. The inner seal is created upon a lid inner seal surface coming into contact with a base inner seal surface. The outer seal is created upon a lid outer seal surface coming into contact with a base outer seal surface. The lid inner seal surface and lid outer seal surface are joined by a lid lip transition surface. The base inner seal surface and the base outer seal surface are joined by a base lip transition surface.
- In one embodiment of the present invention, the termination of the material that comprises the lid is in substantially the same plane, defining the edge of the lid. In one embodiment of the present invention, the termination of the material that comprises the base is in substantially the same plane, defining the edge of the base.
- The lid lip and the base lip each further comprise at least one handle region, and preferably comprise two handle regions, the handle regions being located on substantially opposite ends of the container where two are present. The lid lip transition surface, in each of the handle regions on the lid lip, comprises at least one lid surface area reduction notch. The base lip transition surface, in each of the handle regions on the base lip, comprises at least one base surface area reduction notch.
- In one embodiment of the present invention, the base further comprises at least one base de-nesting notch. In one embodiment of the present invention, the lid further comprises at least one lid de-nesting notch.
- In an embodiment of the present invention, the upper lid surface further comprises at least one vent. In an embodiment of the present invention, the lower base surface comprises at least one vent-complimentary notch.
- In one embodiment of the present invention, the lower base surface further comprises a raised food-resting surface. In one embodiment of the present invention, the upper lid surface further comprises a raised base-engaging surface.
- In one embodiment of the present invention, the lower base surface further comprises at least one fluid separation notch.
