Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a lid for cooking utensils used in general households.

BACKGROUND ART Conventional lids for cooking utensils of this type are disclosed in Japanese Utility Model Publication No. 59-41761, for example.
The structure was as shown in the figure.

In other words, the lid 1 is rotatably supported on one side of the cooking utensil body and covers the upper opening of the cooking utensil body, and includes an upper lid 2 that forms the outer contour of the upper surface, and a ring-shaped ring located on the outer periphery of the lower surface of the lid 1. lid body cover 3 and lid body 1
It has a lower lid 4 made of metal and a deformation prevention metal fitting 5 having a substantially U-shaped cross section, and the lid cover 3, the lower lid 4, and the deformation prevention metal fitting 5 are fixed together with screws 6. By doing so, the lower lid body 7 was constructed.

Problems to be Solved by the Invention However, in such a configuration, the lower lid body 7 and the upper lid 2 are constructed by fixing the lid body cover 3, the lower lid 4, and the deformation prevention fitting 5 with screws 6.
When connecting these, the lower lid body 7 is made close to a strong rigid body because this is done only at its outer periphery, but the deformation of the upper lid 2 is only suppressed at its outer periphery, and the deformation is only suppressed at its center. This means that no suppressive force is acting on the upper lid 2, and since the upper lid 2 is generally made of synthetic resin or a thin stainless steel plate, which itself has low strength, the upper lid 2 is used to prevent When exposed to heat or pressure inside the pot, deformation occurs between the outer periphery and the center. This causes a relative positional shift between the main body and the shaft support or locking portion provided on the lid 1, which impedes smooth rotation and reliable locking of the main body and the lid 1, and There was a problem in that the gap between the main body and the lid 1 became large and the appearance deteriorated.

Further, when the upper lid 3 is made of synthetic resin, the assembled lid 1 has a shape that is subjected to the molding distortion of the upper lid 2 due to distortion during its molding, which further exacerbates the above-mentioned problem.

The present invention was made to solve these problems, and an object of the present invention is to provide a lid for a cooking utensil that does not deform even when subjected to heat generated during cooking or pressure inside the pot. .

Means for Solving the Problems In order to solve the above problems, the present invention includes an upper lid made of synthetic resin that constitutes the upper surface of the lid body, and a lower lid made of synthetic resin that constitutes the lower surface of the lid body. A deformation-preventing metal fitting is fixed to either the upper cover or the lower cover in the internal space where the deformation-preventing metal fitting is fixed, and the outer periphery of the upper cover and the lower cover is A protrusion is provided that comes into contact with the deformation prevention fitting before joining at the portion.

Function According to this configuration, the deformation prevention metal fitting and the protrusion come into contact with each other before the upper cover and the lower cover are joined at the outer periphery, so when the cover body is assembled, the upper cover or the lower cover having the protrusion may be slightly deformed. Since it is possible to absorb the shape distortion that occurs when the top or bottom lid is molded with synthetic resin, the assembled lid is always kept in a constant shape, and as a result, distortions that occur during cooking can be absorbed. The lid does not deform even when subjected to heat or pressure inside the pot, so the lid, which is pivoted on the cookware body, can rotate smoothly and lock securely, making it easier to cook. Since the gap between the device body and the lid body can be kept to a certain level initially set, a good appearance can be achieved.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 4. In the figure, 11 is the main body of the cooking utensil, 12 is a double-structured lid that covers the top opening of the main body 11, 13 is a shaft that rotatably supports the main body 11 and the lid 12, and 14 is the top surface of the main body 11. A locking lever that locks the lid 12 to the main body 11 with the opening closed by the lid 12; 15 is a synthetic resin upper lid that forms the outer contour of the upper surface of the lid 12; 16 is the outer periphery of the lower surface of the lid 12; a ring-shaped lid cover located at 17, a lower lid made of synthetic resin constituting the lower surface of the lid 12;
Reference numeral 8 denotes a deformation prevention metal fitting having a substantially U-shaped cross section and fixed to the lower lid 15, and is made of a metal plate. 19 is a screw that fixes and integrates the lid cover 16, the lower lid 17, and the deformation prevention fitting 18; 20 is a screw that is provided in the center of the upper lid 15, and is installed before the upper lid 15 and the lower lid 17 are joined at the outer periphery; This is a protrusion that comes into contact with the deformation prevention fitting 18.

In the above configuration, the lid body cover 16 and the lower lid 17
The deformation prevention fitting 18 is fixed together with screws 19 to constitute a lower lid body which is a single rigid body, and this lower lid body is fitted to the upper lid 15 at its outer periphery. Further, the protrusion 20 and the deformation prevention metal fitting 18 provided at the center of the upper lid 15 come into contact with each other before the upper lid 15 and the lower lid body are fitted together at their outer peripheries, causing the upper lid 15 to slightly deform. This completes the fitting process, and this allows the shape distortion that occurs when the top lid 15 is molded from synthetic resin to be absorbed, so that the assembled lid 12 is always kept in a constant shape. As a result, the lid body 12 will not be deformed even if it receives heat generated during cooking or pressure inside the pot.

In the above embodiment, the upper lid 15 is provided with the protrusion 20, and the lower lid 17 is provided with the deformation prevention fitting 18.
In the above description, a deformation prevention metal fitting is provided on the upper lid 15 side, and a lower lid 17 is provided on the upper lid 15 side.
Even if a protrusion is provided on the side to make them contact each other,
This embodiment provides the same effects as the above embodiment.

Effects of the Invention As described above, according to the present invention, the deformation prevention metal fittings and the protrusions come into contact with each other before the synthetic resin upper and lower lids are combined at the outer periphery, so that it is easier to assemble the lid body. Sometimes, the top or bottom lid with protrusions deforms slightly to absorb the shape distortion that occurs when the top or bottom lid is molded with synthetic resin, so the assembled lid always maintains a constant shape. As a result, the lid does not deform even when exposed to the heat generated during cooking or the pressure inside the pot, so the lid, which is pivoted on the cookware body, can rotate smoothly. In addition, reliable locking can be obtained, and since the gap between the cooking utensil body and the lid can be kept to a certain small value initially set, a good appearance can be achieved.
