The present invention relates to food service vessels and, more particularly, to vessels for containing and serving food items providing thermal insulation to the hot or cold food items carried therein.
In one aspect of the present invention, a stainless steel food service vessel, includes a vessel body formed of stainless steel. The vessel body has a top opening and a dual wall construction formed by an interior wall and an exterior wall. The interior wall defines an internal cavity for containing a food item. An insulating cavity is defined in a void between the interior wall and the exterior wall, and the void is contained by a joining seal between the interior wall and the exterior wall. An annular rim is defined by a juncture of the interior wall and the exterior wall surrounding the top opening.
A lid may be received within the annular rim and is configured to seal around the annular rim to contain food items within the internal cavity. In some embodiments the lid includes a cylindrical constriction to be received within the annular rim. The cylindrical constriction is formed to have a diameter dimensioned to receive one of a beverage can or a beverage bottle. In other embodiments, the lid may be configured as a serving dish that is configured to be received within the annular rim of the top opening. In other embodiments, the lid is threadingly received within the top opening by a plurality of internal threads defined in the interior wall around a periphery of the top opening. Alternatively, a plurality of external threads are defined in the exterior wall around a periphery of the top opening.
Preferably, the exterior wall and the interior wall are substantially parallel throughout a majority of the vessel body. The insulating cavity may be filled with an insulating fluid. Alternatively, the void within the insulating cavity may comprise a vacuum.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Broadly, embodiments of the present invention provide an improved food service vessel for containing food items, such as liquid beverages, sauces, dips, yogurt, ice cream, and the like. The food service vessel is formed of a double walled stainless steel construction to insulate the food items carried by the vessel.
As seen in reference to the drawings of
The vessel body may 12 may be formed in a variety of shapes and styles such that the interior wall 16 and the exterior wall 18 are defined substantially parallel to each other throughout the shape of the vessel body 12. By way of non-limiting example, the body may be configured as a bottle, a glass, a dish, a holder for another food service vessel, such as a beverage can or bottle. The vessel body 12 may also include a carrying or holding handle extending from the exterior wall 18. In other embodiments, the vessel body 12 may include a stem support 17 extending from the base 15.
An insulating cavity 22 is defined by a void between the interior wall 16 and the exterior wall 18. The void is contained by a joining seal between the interior wall 16 and the exterior wall 18. An annular rim 24 is defined by a juncture of the interior wall 16 and the exterior wall 18 that surrounds the top opening 14. The joining seal may be defined around the annular rim 24 or around the base 15.
A lid 26 may be received within the annular rim 24. The lid 26 is configured to seal around or within the annular rim 24 to contain food items within the internal cavity 20 without leakage. The lid 26 may be configured for an interference fit for frictional engagement with the annular rim 24 and or the interior wall 16 proximal to the top opening 14.
As seen in reference to
As seen in reference to the drawings of
In yet other embodiments of the food service vessel, such as shown in reference to
The exterior wall 18 and the interior wall 16 may be defined in a wide variety of profiles such that they are substantially parallel throughout a majority of the vessel body 10. The superior insulating properties of stainless steel are improved with an insulating cavity 20, which may be filled with an insulating fluid. Alternatively, the void within the insulating cavity 20 may be evacuated under a vacuum before the interior wall 16 and the exterior wall 18 are sealingly joined, such as by a weld, to one another.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
