Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an attachment structure for a reinforcing ring that covers the peripheral edge of a pot lid whose main material is tempered glass or enamel.

[Conventional technology]

In general, for pot lids that are mainly made of tempered glass, the strength of the periphery is increased (tempered glass has excellent impact resistance against impacts from the front or back side, but on the other hand, Rings of various shapes (hereinafter referred to as "reinforcement rings") are fitted to the upper peripheral edge, which is necessary to improve the appearance (having the characteristic of being extremely brittle) and to improve the appearance. (A reinforcing ring is also fitted to a pot lid whose main material is enamel to improve its appearance.) Fig. 21 is a drawing showing the specific structure of the pot lid, and shows how the reinforcing ring is attached to the periphery of the lid body a. The cross-sectional shape is C
A reinforcing ring b formed in the shape of a letter is integrally fitted with the lid main body a with a space c between the reinforcing ring b and the lid body a.

[Problem that the invention attempts to solve]

However, in the case of the reinforcing ring b of the conventional structure described above, boiled liquid (during cooking) and washing water (during cleaning) infiltrate into the space c, and these boiled liquid and washing water evaporate and dry. The problem is that cooking scraps, water scale, detergent, etc. (grease) that have entered the boiled soup or washing water after washing accumulate in the space c.
In other words, the problem is that it is unsanitary and gives a feeling of uncleanliness, but the reinforcing ring b of the conventional structure is attached by being integrally fitted to the lid body a, and the inside of the space c is The problem is that it is not possible to remove the grease that has accumulated on the surface.

The present invention is an attempt to improve the above-mentioned problems, and the problem to be solved lies in making it possible to remove the grease.

The specific means and effects for solving the above problems are as follows.

[Means for solving problems]

The reinforcing ring is divided into a lower ring piece that covers the end face and a part of the back side of the lid body, and an upper ring piece that covers a part of the end face and surface of the lid body, and both ring pieces can be attached and detached from the periphery of the lid body. Attach by fitting freely.

[Effect]

By pulling the upper ring piece and the lower ring piece in the vertical direction, the reinforcing ring can be removed from the lid body, and the grease accumulated in the space of the reinforcing ring can be removed.
