Description

[Detailed description of the invention] (Field of industrial application) The invention is a cooking container such as a pot used in general households. Specifically, the present invention relates to an improvement in a cooking container that enables low-pressure hermetically sealed cooking inside the container using a water seal.

(Prior art) Traditionally, deep dish containers (1973-
9010) was received. This deep dish container has annular grooves carved into the outer peripheries of both the annular edges of the deep dish and the lid, leaving edge frames, and the cylindrical frame has grooves carved into the top surface of the annular shape so that the entire periphery of each is in close contact with each other. The structure is a combination of a cylindrical container and a cylindrical frame.

In addition, a pot (opened in 1970) was used as another cooking container.
40552) was also hot. This pot has a structure in which a wall at the upper end of the pot is bent outward to form a groove, and the entire circumferential edge of the lid is placed closely on the wall at the upper end.

In the former deep dish container, food is placed in a deep dish, the lid is closed, the lower annular edge frame of the cylindrical frame is fitted into the annular groove of the lid, and then the annular groove of the top of the cylindrical frame is fitted. The containers are stacked and used by fitting the protruding surfaces provided on the back side of the deep dish. In addition, the latter pot has a horizontal step edge formed at the opening edge of the lid fitted into an upper end wall formed at the opening peripheral edge of the pot.

(Problem to be solved by the invention) However, in the former deep dish container, when the lid is fitted into the deep dish, the annular projecting surface of the lid is fitted into the annular groove formed at the upper end of the deep dish. In addition, since the latter pot also simply places the stepped edge of the lid on the upper wall formed around the opening of the pot, there is a water seal at the fitting portion of each lid, that is, the fitting edge and It is not possible to improve the sealing efficiency by forming a water film between the edges and the rim. Therefore, during cooking, the water sealing effect of the film of steam, oil, etc. in the contents makes it possible to seal the container at a constant temperature and low pressure, which improves thermal efficiency ( It is not possible to raise the heat level (low or medium heat) and requires extra water and oil, so there is a lot of loss of vitamins and minerals in the food, and the flavor and nutrients are lost. There were problems such as the loss of flavor and the inability to obtain a colorful finish to vegetables.

The object of the present invention is to provide a cooking container that eliminates the above-mentioned problems.

(Means for Solving the Problems) In order to achieve the above object, the cooking container of the present invention includes a container having a raised edge extending upward from an outward placing edge on the periphery of the opening; In a cooking container comprising a plate-shaped lid provided with a sideways rim, a raised rim is provided on the inner peripheral side of the mounting rim of the container,

A wave-shaped void is provided between the depression rim and the depression rim bottom to form a large and small void configuration.

(Function) After putting food to be cooked into the container 1 constituting a pot or the like, the lid 6 is placed over the container 1, and the horizontal flange 7 formed around the opening of the lid 6 is placed on the placement edge 2 of the container 1. The abutment part 11 is placed on the mounting edge 2, and the abutment part 11 is brought into contact with the raised edge 9 provided on the mounting edge 2, and the contact part 11 is formed in an endless shape along the mounting edge 2 of the container 1 between the outer peripheral side of the container 1. Water, etc. 13 is contained in the wave-shaped gap S portion, and this water, etc. 13 acts as a seal, and the raised edge 9
The lid 6 is airtightly fitted onto the container 1 by the close contact of the abutting portion 11 to the container 1 and the sealing by a water film, and then the lid 6 is heated and boiled in a heater.

(Example) Next, a first example of the cooking container according to the present invention will be described based on the drawings 1 to 3. In the figure, 1 is a container constituting a two-handled pot A, and the periphery of the opening is An outward facing raised edge 3 is provided, and a pair of handles 4, 5 are attached to the outer peripheral wall.

Reference numeral 6 denotes a lid that fits over the opening of the container 1, and has a dish-shaped cross section with a sideways flange 7 around the opening, and has a knob 8 protruding from the center of the top surface.

Reference numerals 9 and 10 denote a raised edge provided on the inner peripheral side of the mounting edge 2 of the container 1 and a recessed edge provided on the outer peripheral side. is concave downward in an arc shape.

Reference numeral 11 denotes an abutting portion provided on the inner circumferential side of the wavy side flange 7 of the lid body 6, and is formed in an arcuate shape so as to fit in with the raised edge 9 of the container 1.

S is a wave-shaped gap formed between the outer peripheral side of the lid body 6 and the recess edge 10 of the container 1, and S is a wave-shaped gap formed between the outer peripheral side of the lid body 6 and the recess edge 10 of the container 1, and is determined by the curvature of the recess edge bottom 12 and the horizontal flange edge formed in the wave shape of the lid body 6. This shows a wave-shaped void obtained by changing the curvature of the outer circumferential portion in 7, and is formed in an endless shape along the hollow edge 10 and the sideways flange edge 7, and water, etc. 13 is poured into this wave-shaped void S during boiling. Internally acts as a seal,
The cap 6 is tightly fitted onto the container 1.

When using the two-handed pot according to the first embodiment, cover the container 1 with the lid 6, place the sideways flange 7 of this on the mounting edge 2 of the container 1, and create a raised area on the mounting edge 2. Fit the abutment part 11 to the edge 9, and
A wave-shaped gap S having large and small gaps is formed between the recessed edge 10 and the outer circumferential side of the lid body 6, and water or the like 13 is filled in this wave-shaped gap S and the water or the like 13 acts as a seal. the contact portion 11 to the raised edge 9.
The close fitting of the cap 6 and the sealing of the wave-shaped gap S by the water film enable the lid body 6 to be fitted in an airtight manner.

Next, the second embodiment will be explained based on FIG. The arc of the abutting part 11 on the lid body 6 is made smaller than the arc of 9, and a wave-shaped gap S (small gap and large gap) is formed by the size of this arc surface,
