Abstract

A slow cooker for heating food stuffs includes a housing defining a heating cavity and a housing rim. A heating element is disposed within the housing to heat the heating cavity. A container has a generally hollow interior and a container rim and is shaped and sized to fit within the heating cavity for heating thereof by the heating element. A lid is sized and shaped to at least partially cover an opening of the container and includes a gasket around an outer edge thereof for sealing engagement with the container rim. The slow cooker further includes at least one clip for selectively retaining the lid in sealing engagement with the container rim to inhibit leakage of the food stuffs. The at least one clip is an over-the-center clip and includes a hook and a catch to selectively retain the lid in sealing engagement with the container rim.

Claims (22)

1. A slow cooker for heating of food stuffs, the slow cooker comprising:

a housing having a base and a side wall extending therefrom to define a heating cavity within the housing, the housing further having a housing rim at a first, free edge of the side wall defining an opening to the heating cavity;

a heating element disposed within the housing sufficiently proximate the heating cavity to heat the heating 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 the food stuffs therein, the container being shaped and sized to fit within the heating cavity of the housing for heating thereof by the heating element;

a lid sized and shaped to at least partially cover the opening of the container when placed on the container rim, the lid having a gasket around an outer edge thereof for sealing engagement with the container rim; and

at least one clip mounted between the lid and the side wall of the housing, the at least one clip being an over-the-center clip having a hook and a catch, one of the hook and catch being mounted on one of the lid and side wall of the housing and the other of the hook and catch being mounted on the other of the lid and side wall of the housing, the at least one clip being selectively engageable with the lid and side wall of the housing to selectively retain the lid in sealing engagement with the container rim to inhibit leakage of the food stuffs from the interior of the container, wherein the housing and lid have a vertical height, the at least one clip being disposed entirely within the vertical height of the housing and lid to facilitate storage and transport of the slow cooker when the at least one clip is engaged with the lid and side wall of the housing.

2. The slow cooker of claim 1 , wherein the at least one clip is releasably engageable with the lid, such that, in an engaged position, the at least one clip retains the gasket of the lid in sealing engagement with the container rim and, in a released position, the lid can be removed from the container to allow access to the interior of the container.

3. A slow cooker for heating of food stuffs, the slow cooker comprising:

a housing having a base and a side wall extending therefrom to define a heating cavity within the housing, the housing further having a housing rim at a first, free edge of the side wall defining an opening to the heating cavity;

a heating element disposed within the housing sufficiently proximate the heating cavity to heat the heating 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 the food stuffs therein, the container being shaped and sized to fit within the heating cavity of the housing for heating thereof by the heating element;

a lid sized and shaped to at least partially cover the opening of the container when placed on the container rim, the lid having a gasket around an outer edge thereof for sealing engagement with the container rim; and

at least one clip mounted between the lid and the side wall of the housing, the at least one clip being an over-the-center clip having a hook and a catch, one of the hook and catch being mounted on one of the lid and side wall of the housing and the other of the hook and catch being mounted on the other of the lid and side wall of the housing, the over-the-center clip including a lever and the hook being shaped to extend from the lever and around the container rim when the container is disposed within the heating cavity of the housing, the at least one clip being selectively engageable with the lid and side wall of the housing to selectively retain the lid in sealing engagement with the container rim to inhibit leakage of the food stuffs from the interior of the container, wherein the housing and lid have a vertical height, the at least one clip being disposed entirely within the vertical height of the housing and lid to facilitate storage and transport of the slow cooker when the at least one clip is engaged with the lid and side wall of the housing.

4. The slow cooker of claim 3 , wherein when the hook is placed around the catch, the lever is rotated to create a retaining force exerted by the clip on the lid in order to retain the lid on the container rim.

5. The slow cooker of claim 1 , wherein the catch is in the form of a small, slightly hooked, elongate protrusion to selectively engage the hook of the clip.

6. A slow cooker for heating of food stuffs, the slow cooker comprising:

a housing having a base and a side wall extending therefrom to define a heating cavity within the housing, the housing further having a housing rim at a first, free edge of the side wall defining an opening to the heating cavity, the housing including two diametrically opposed handles disposed along a major axis of the housing and extending outwardly therefrom to enable the user to grasp and lift the assembled slow cooker for movement thereof;

a heating element disposed within the housing sufficiently proximate the heating cavity to heat the heating 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 the food stuffs therein, the container being shaped and sized to fit within the heating cavity of the housing for heating thereof by the heating element;

a lid sized and shaped to at least partially cover the opening of the container when laced on the container rim, the lid having a gasket around an outer edge thereof for sealing engagement with the container rim; and

two clips mounted between the lid and the side wall of the housing in diametrically opposed relation, the clips being aligned with the handles, each clip being an over-the-center clip having a hook and a catch, one of the hook and catch of each clip being mounted on one of the lid and side wall of the housing and the other of the hook and catch of each clip being mounted on the other of the lid and side wall of the housing, each clip being selectively engageable with the lid and side wall of the housing to selectively retain the lid in sealing engagement with the container rim to inhibit leakage of the food stuffs from the interior of the container, wherein the housing and lid have a vertical height, each clip being disposed entirely within the vertical height of the housing and lid to facilitate storage and transport of the slow cooker when each clip is engaged with the lid and side wall of the housing.

7. The slow cooker of claim 6 , wherein each over-the-center clip has a lever and the hook of each over-the-center clip is shaped to extend from the lever and around the container rim when the container is disposed within the heating cavity of the housing.
