Description

[Detailed description of the invention] (Field of industrial application) This invention allows the ring member to be installed without any problem even if there is a caliber error in the opening for fitting the lid of the container, and the tight fitting of the lid can be maintained for a long time. It relates to a cooking container that can be used for cooking.

(Prior art) Conventionally, metal ring members have been attached to the opening rim of the container and the lid body, which are made of materials that are difficult to bend, such as enamel or glass products, for the purpose of protecting the edges or for decoration. Surrounded cooking containers are known.

In addition, as disclosed in Japanese Utility Model Publication No. 60-37054, as a whistle-blowing water heater that can easily and easily set the fitting retention force between the opening and the lid to an appropriate state, there is a structure on the top wall of the water heater body. A cylindrical opening wall is formed, and a lid body that fits into the opening wall has a lid wall larger than the opening diameter so as to be located above the opening of the opening wall, and a strong toughness that protrudes downward from the lid wall. It is composed of a cylindrical wall made of a certain thin metal material and a knob provided on the upper surface of the lid wall, and protrusions are provided at multiple locations at intervals in the circumferential direction near the lower end of the outer peripheral surface of the cylindrical wall. A configuration has been proposed.

(Means for Solving the Problem) However, in the case of a water heater having a configuration in which a convex portion is formed on the cylindrical wall formed at the peripheral end of the lid, the cylindrical wall itself has elasticity, and furthermore, the cylindrical wall itself has elasticity. Since a convex portion is formed on the free end, when the lid is closed, repeated concentrated loads are applied only to the convex portion and its vicinity, resulting in deterioration of elastic force, and combined with heating during cooking, the elasticity of the cylindrical wall decreases. There was a problem in that it became difficult to maintain a tightly fitted state of the lid body in a relatively short period of time.

The present invention was made in order to solve the above-mentioned conventional problems, and it improves each ring member attached to the container or the container and the lid, and improves the connection between the edge of the opening periphery of the container and the base of the ring member. A gap is provided between the two sides, protrusions are provided at intervals on the base for a close fit with the lid body, and an inset part is provided on the periphery of the lid body, and a hakama edge extends from this inset part. To prevent concentrated load from being applied only to specific parts of the hakama edge,
The purpose of the present invention is to provide a cooking container that can maintain the tight fit of a lid over a long period of time without causing deterioration of elasticity at the edge of a hakama.

(Means for Solving the Problems) A cooking container according to the present invention for achieving the above object is a cooking container in which a ring member is provided around the opening of the container and a lid is fitted onto the container. The end face of the opening periphery of the container and the base of a container ring member comprising upper and lower gripping parts and a base connecting the gripping parts are arranged at intervals, and a fitting part is provided on the periphery of the lid; A hakama edge extending from the fitting portion is provided, and protrusions for tightly fitting into the hakama edge are provided at a plurality of intervals at the base of the container ring member.

A double layer of water is formed between the concave portion 23 and the holding portion 6e of the container 1e, and together with the press fit onto the protrusion 9e, a highly airtight closed state is obtained.

(Effects of the Invention) As described above, the cooking container according to the present invention is a cooking container in which a ring member is provided around the opening of the container and a lid is fitted onto the container, and the end face of the opening of the container, The base of the container ring member consisting of the upper and lower clamping parts and the base connecting the clamping parts are arranged at intervals, and a fitting part is provided on the periphery of the lid body, and a hakama is provided extending from the fitting part. In addition, a plurality of protrusions for tightly fitting to the hakama edge are provided at the base of the container ring member at a plurality of intervals, and the position where the lid is fitted is originally specified. Therefore, unlike conventional products that have a protrusion on the free end side, repeated concentrated loads are not applied to the protrusion and its vicinity, so the elastic force of the hakama edge of the lid body is reduced. It does not deteriorate and has the unique effect of allowing the lid to be tightly fitted over a long period of time, and even if dimensional errors occur between the container and the ring member, it will not cause any problems in processing. Not at all.
