Description

[Detailed description of the invention] This invention applies to electric heat-insulating containers and electric rice-cooking containers (including both those with and without heat-insulating functions).
Concerning improvement of container lids such as.

Conventionally, in order to improve the design effect by using two-tone colors, it has been desired to make the peripheral part and the central part of the upper lid body different in color.
Therefore, it may be possible to adopt a method of attaching a heat-welded seal to the integrally molded upper lid, but in this case, it is difficult to attach the seal in the correct position, and the work requires time. be. As a solution to this drawback, Utility Model No. 51-159259
As is known from the publication, a peripheral lid body constituting the peripheral part of the top lid body and a central lid body constituting the central part of the top lid body are formed separately, and the two are combined to form the top lid body. This makes it possible to make the two colors different.

However, according to the above-mentioned conventional example, since the upper lid is separate, the number of parts constituting the lid of the container increases, and the associated assembly work is time-consuming.

The present invention solves this problem by constructing an upper lid by combining a peripheral lid with an opening in the center and a central lid whose outer peripheral edge overlaps the inner peripheral edge of the peripheral lid. The first feature is that the handle is solved by integrally molding the lower part of the handle (this integrally molded part is referred to as the central member) and fixing the upper handle member thereto.

In addition, in the conventional example described above, it is difficult to seal the central lid body and the peripheral lid body, which are made of separate members, and if it is incomplete, water can leak through the joint between the two.
This creates the problem that dust can easily enter the inside of the lid, so it is necessary to firmly fix the two together.
For example, it may be possible to adopt a method known from Japanese Utility Model Application Publication No. 49-79859, in which the outer peripheral edge of the upper lid body is joined to a step provided on the peripheral rising part of the lower lid body with a concave central part. It will be done. However, the connection between this step and the outer edge is not yet sufficient, and since the structure is such that screws are directly attached to the connection, the connection strength is weak, and the connection between the central lid and the peripheral lid is still poor. It is not possible to combine the seal completely.

The present invention solves this problem by providing an annular recess on the inner peripheral edge of the peripheral lid, and an annular convex part that fits into the recess on the outer peripheral edge of the central lid. The second feature is that the problem is solved by fixing the convex part and the concave part in a press-fit state by fixing them to the lid using a fixing means.
