Abstract

A kitchen appliance includes a housing that defines a cavity. The housing has a housing rim defining an opening to the cavity. A heating or cooling element is disposed within the housing to heat or cool the cavity. A container has a generally hollow interior and a container rim. A lid is sized and shaped to at least partially cover the opening of the container when placed on the container. The lid has an exterior surface and an opposing interior surface. At least one handle is pivotally mounted to one of the exterior surface of the side wall of the housing and the exterior surface of the lid. The handle is pivotable between an engaged position to retain the lid in sealing engagement with the container rim and disengage position to permit the lid to be removed from the container rim.

Claims

1. A kitchen appliance comprising:

a housing having a base and a side wall extending therefrom, the side wall having an exterior surface and an opposing interior surface, at least portions of the interior surface of the side wall and base defining a cavity within the housing, the housing having a housing rim at a first, free edge of the side wall defining an opening to the cavity;

a heating or cooling element disposed within the housing proximate the cavity to heat or cool the cavity;

a container having a generally hollow interior and a container rim defining an opening for accessing the interior thereof, the interior being capable of retaining contents therein, the container being sized and shaped to fit within the cavity of the housing;

a lid sized and shaped to at least partially cover the opening of the container when placed on the container, the lid having an exterior surface and an opposing interior surface facing the interior of the container when the lid is placed on the container;

at least one handle pivotally mounted to one of the exterior surface of the side wall of the housing and the exterior surface of the lid, the handle being pivotable between an engaged position in which at least a portion of the handle contacts one of the lid and the side wall of the housing to retain the lid in sealing engagement with the container rim for inhibiting leakage of the contents from the interior of the container and a disengaged position in which the portion of the handle is spaced-apart from the other one of the lid and the side wall of the housing to permit the lid to be removed from the container rim;

the handle includes a first end, an opposing second end and a connection portion extending therebetween and further comprising an arcuate extension extending across an entire width of the handle as measured from the first end to the second end and an opening in the handle formed between the extension and at least a portion of the connection portion; and

a gasket extending around one of an outer edge of the lid and the container rim for sealing engagement with the other of the container rim and the outer edge of the lid, the gasket being at least partially compressed when the at least one handle is in the engaged position.

2. The kitchen appliance according to claim 1, wherein each of the first end and the second end being pivotally mounted to one of the exterior surface of the side wall of the housing and the exterior surface of the lid.

3. The kitchen appliance according to claim 2, wherein the extension extends inwardly from the connection portion of the handle, the extension being fixed with respect to the connection portion, the extension contacting one of the exterior surface of the lid and the exterior surface of the side wall of the housing in the engaged position.

4. The kitchen appliance according to claim 3, wherein the extension of the connection portion of the handle snaps over at least a portion of the container rim when the handle is moved from the disengaged position to the engaged position.

5. The kitchen appliance according to claim 1, wherein the lid further comprises a pad with at least a portion of the pad extending outwardly beyond an outer edge of the lid.

6. The kitchen appliance according to claim 1, wherein one of the exterior surface of the lid and the exterior surface of the side wall of the housing includes at least one depression and the handle includes at least one complementary extension, the extension being fixedly attached to the handle, the extension extending at least partially into the depression when the handle is in the engaged position.

7. The kitchen appliance according to claim 1, wherein at least a portion of the handle is biased toward the disengaged position.

8. The kitchen appliance according to claim 1, wherein in the disengaged position at least a portion of the handle extends generally perpendicularly to a support surface when the base of the housing rests on the support surface, and wherein in the engaged position the portion of the handle extends generally parallel to the support surface.

9. The kitchen appliance according to claim 8, wherein a pivot point of the handle is located above the container rim.

10. The kitchen appliance according to claim 1, wherein one of the exterior surface of the lid and the exterior surface of the side wall of the housing includes two laterally spaced-apart protrusions, at least a portion of the handle being positioned between the protrusions when in the engaged position.

11. The kitchen appliance according to claim 1, wherein the handle is formed of an elastomeric material.

12. The kitchen appliance according to claim 11, wherein the handle includes an opening therein, one of the exterior surface of the lid and the exterior surface of the side wall of the housing including a catch extending outwardly therefrom, the opening of the handle surrounding at least a portion of the catch when the handle is in the engaged position.
