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 latching mechanism or handle is operable to seal the contents of the appliance within the appliance.

First claim

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 element disposed within the housing proximate the cavity to heat 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, first and second projections extending radially outwardly from the container rim beyond the housing and being positioned generally diametrically opposed on the container rim; 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, an opposing interior surface facing the interior of the container when the lid is placed on the container, and a lid knob extending outwardly or upwardly from the exterior surface of the lid and including an upper gripping handle; and an elongated latching member having a middle portion that extends at least over the width of the lid and the width of the container, the middle portion including an opening generally centrally located with respect to the exterior surface of the lid, a portion of the lid knob extending through the opening into engagement with the lid such that the latching member is rotatably mounted on the lid, and opposing first and second generally L-shaped end portions that extend from opposite ends of the middle portion downwardly and radially inwardly, the latching member being rotatable to an engaged position wherein the generally L-shaped end portions extend around and beneath the first and second projections into engagement with an underside thereof, respectively, to releasably interlock the lid to the container, the latching member being rotatable to a disengaged position wherein the first and second generally L-shaped end portions are spaced from the first and second projections to permit removal of the lid from the container.

2 . The kitchen appliance of claim 8 , wherein the opening has an internal diameter at least slightly larger than an external diameter of the portion of the lid knob extending through the opening enabling the latching member to rotate with respect to the lid knob, the lid, the container and/or the housing.

3 . The kitchen appliance of claim 8 , wherein the lid, first and second projections and first and second L-shaped end portions are dimensioned such that with the latching member in the engaged position the lid is retained in sealing engagement with the container rim for inhibiting leakage of the contents from the interior of the container.

11 . The kitchen appliance of claim 8 , wherein the elongated member is inseparably mounted to the lid and the lid knob.

12 . The kitchen appliance according to claim 8 , further comprising a flexible gasket positioned between the lid and container, the gasket being at least partially compressed when the latching member is in the engaged position.

13 . The kitchen appliance of claim 8 , wherein the first and second projections have a projection width, a width of the L-shaped end portions being generally equal to the projection width.
