[Industrial applications]

 This invention relates to a pressure cooker for cooking.

[0002]

[Prior art]

 For example, Japanese Patent Application Laid-Open No. 6-78850 describes what is called a "pressure cooker". In this cooker, the engaging pieces are provided separately on the opening edge of the container, and the engaging pieces are also provided on the outer peripheral edge of the lid so as to cover the container. The lid is rotated, the engaging pieces of the lid are overlapped with the underside of the engaging pieces of the container, and the lid is engaged with the container. Since the packing is arranged along the inner circumference of the lid, when this lid is engaged with the container, the packing is sandwiched between the lid and the container, and the lid and the container are airtight. Be kept in a state.

In addition, the handle of the lid is provided with first and second sliding bodies. These sliding bodies are biased inwardly of the lid and project inside the lid through holes on the outer periphery of the lid. In the state where the lid is simply put on the container, the first sliding body hits the packing and deforms the packing, so that a gap is formed between the lid and the container. In this case, heating the container does not increase the pressure inside the cooker. Further, when the lid is rotated and the lid is engaged with the container, the first sliding body is brought into contact with the engaging piece of the container and moved outward, and the second sliding body is engaged with the container. Fit in the recess of the piece. When the first sliding body moves outward, the first sliding body separates from the packing, so that the packing returns to its original shape and maintains the airtight state between the lid body and the container.

[0004]

[Problems to be solved by the device]

 By the way, when the lid is engaged with the container, the first and second sliding bodies of the handle of the lid come into contact with the engaging pieces of the container. At this time, the engaging pieces of the lid and the engaging pieces of the container overlap each other. Therefore, the first and second sliding pieces are arranged at the positions where the engaging pieces of the lid should be.

However, as far as the respective drawings of the above-mentioned Japanese Patent Laid-Open No. 6-78850 are seen, the engaging pieces of the lid are not provided at the positions of the first and second sliding pieces, and this Chips have been omitted. In this case, since the lid body and the container body do not engage with each other at the portion where the engaging piece is omitted, the pressure easily leaks.

Further, when this engaging piece is provided without omitting this engaging piece, a hole through which the first and second sliding pieces pass is formed in a portion adjacent to this engaging piece. However, the shape of this portion becomes complicated, and it becomes difficult to mold and manufacture the lid.

Therefore, an object of the present invention is to provide a pressure cooker that is easy to manufacture and can reduce the cost.

[0008]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention comprises a container and a lid for the container, and a plurality of engaging flanges protruding outward are formed at a peripheral edge of the opening of the container so as to separate the periphery of the lid. A plurality of engaging flanges projecting inward are formed on the edge so as to be spaced apart from each other, and annular packings are stacked on the engaging flanges of the lid, and the engaging flanges of the container and the engaging flanges of the lid are arranged. Put the lid on the container with the collars staggered, and then rotate the lid so that the engaging collars on the lid are superposed under the engaging collars on the container. In a pressure cooker that engages the container and the lid with the packing sandwiched, a lower handle is provided between the engaging collars on the periphery of the container, and when the container and the lid are engaged, the lower handle is An upper grip that overlaps with the upper grip is provided between the engaging flanges on the periphery of the lid, and a first moving piece and a second moving piece are movably provided on the upper grip. The first moving piece is urged inwardly of the lid and the second moving piece is urged outwardly of the lid by the knuckle, and the pressing end of the first moving piece is passed through a hole in the periphery of the lid. It is made to project inward, and this pressing end is pressed against the annular packing, and the guide end of the first moving piece and the guide end of the second moving piece are made to project below the upper handle, and as the lid rotates. , When the upper handle and the lower handle overlap, a guide groove is formed on the lower handle so that the inner end of the first moving piece of the upper handle and the guide end of the second moving piece slide into each other. The guide groove moves the first moving piece outward of the lid when the upper handle and the lower handle overlap each other to separate the pressing end portion of the first moving piece from the annular packing, and Fit the moving piece and stop the rotation of the lid.

[0009]

[Action]

 In this invention, the first moving piece is biased inwardly of the lid by the spring, and the pressing end portion of the first moving piece is projected to the inside of the lid through the hole at the peripheral edge of the lid. The part is pressed against the annular packing. Therefore, when the lid is simply put on the container, the annular packing is pressed and deformed by the pressing end portion of the first moving piece, and a gap is formed between the lid and the container. In this case, heating the container does not increase the pressure inside the container.

When the lid is rotated, the upper grip and the lower grip are overlapped with each other, the second moving piece of the upper grip is fitted into the groove of the lower grip, and the rotation of the lid is stopped. At this time, the container and the lid are engaged. Further, the groove of the lower grip moves the first moving piece of the upper grip in the outward direction of the lid, so that the pressing end of the first moving piece is separated from the annular packing, and the annular packing retains its original shape. Return to shape. As a result, the entire annular packing is sandwiched between the container and the lid, and the space between the two is kept airtight.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 5 show an embodiment of the pressure cooker of the present invention. This pressure cooker comprises a container 1 and a lid 2. On the periphery of the opening of the container 1, the engaging flanges 3 projecting outward are provided at intervals. Further, as is apparent from FIG. 2, the engaging flanges 4 projecting inward are provided at intervals around the periphery of the lid 2.

As shown by the chain double-dashed line in FIG. 2, the lid 2 is put on the container 1 in a state where the engaging flanges 3 of the container 1 and the engaging flanges 4 of the lid 2 are mutually different. After that, when the lid 2 is rotated in the direction of the arrow A, the engaging flanges 4 of the lid 2 overlap with the engaging flanges 3 of the container 1 and the lid 2 engages with the container 1.

As is apparent from FIG. 3, an annular packing 5 is arranged along the inner circumference of the lid 2. The annular packing 5 is made of synthetic rubber and has a V-shaped cross section. When the container 1 and the lid 2 are engaged with each other, the annular packing 5 is sandwiched between the container 1 and the lid 2, and the space between them is kept airtight.

A lower handle 6 is fixed between the engaging flanges 3 on the outer periphery of the container 1, and a guide groove 7 is formed in the lower handle 6. An upper handle 8 is fixed between the engaging flanges 4 on the outer circumference of the lid 2. Further, a pressure adjusting pipe 9 and a safety valve 10 are provided on the upper surface of the lid 2.

The shaft 12 a of the push button 12 projects into the fitting groove portion 14 through a central hole of the recess 11 of the upper handle 8. A coil spring 13 is fitted in the shaft 12a of the push button 12, and the coil spring 13 biases the push button 12 upward. The pin 15 is inserted into the shaft 12a of the push button 12 on the side of the fitting groove 14, and the pin 15 is hooked on the upper side wall of the fitting groove 14, so that the push button 12 does not pop out and come off. .

As is clear from FIGS. 4 and 5, a first moving piece 16 and a second moving piece 17 are arranged in the fitting groove portion 14 of the upper handle 8. A coil spring 18 is inserted between the moving pieces 16 and 17, and the coil springs 18 separate the moving pieces 16 and 17 from each other. A guide end 16a of the first moving piece 16 and a guide end 17a of the second moving piece 17 protrude from the lower side of the upper handle 8.

The moving pieces 16 and 17 and the coil spring 18 are arranged in the fitting groove portion 14 of the upper handle 8, and then the upper handle 8 is secured by the two bolts 21, the two nuts 22 and the bolt 23. Is fixed to the lid 2.

Here, in a state where the engaging flanges 3 of the container 1 and the engaging flanges 4 of the lid 2 are staggered (indicated by a chain double-dashed line in FIG. 2), the pressing end portion 16a of the first moving piece 16 is Projects into the inside of the lid 2 through the hole 2 a in the periphery of the lid 2 and is pressed against the annular packing 5. Therefore, the annular packing 5 is deformed and a gap is generated between the container 1 and the lid 2. In this case, even if the container 1 is heated, the pressure inside the container 1 does not rise.

Next, the upper handle 8 of the lid 2 is moved in the direction of arrow A in FIG. 2, and the lid 2 is rotated to engage the lid 2 with the container 1. At this time, the guide protrusion 16a of the first moving piece 16 and the guide protrusion 17a of the second moving piece 17 slide into the guide groove 7 of the lower handle 6.

The guide convex portion 16a of the first moving piece 16 is slidably contacted with the inner peripheral wall 7a of the guide groove 7 and is moved outward, and accordingly, the pressing end portion 16b of the first moving piece 16 is moved. Retract outside the lid 2 and away from the annular packing 5. As a result, the annular packing 5 returns to the original circular shape, the entire annular packing 5 is sandwiched between the container 1 and the lid 2, and the space between the two is kept airtight. In this case, when the container 1 is heated, the pressure inside the container 1 rises.

Further, the guide convex portion 17 a of the second moving piece 17 is in sliding contact with the inner peripheral wall 7 b of the guide groove 7 and temporarily moves inward of the lid 2, but reaches the concave portion 7 c of the guide groove 7. The guide convex portion 17a fits into the concave portion 7c. When the guide convex portion 17a is fitted, a sound is generated, so that the upper handle 8 just overlaps with the lower handle 6 and the space between the container 1 and the lid 2 becomes airtight as described above. Can be confirmed.

Next, when removing the lid 2, the push button 12 of the upper handle 8 is pressed. Along with this, the lower end of the push button 12 presses the inclined wall 17b of the second moving piece 17, and the moving piece 17 moves inward of the lid 2. As a result, the guide end 17a of the second moving piece 17 is disengaged from the recess 7c of the guide groove 7, so that the upper handle 8 of the lid 2 is moved in the direction of arrow B in FIG. 2 can be returned to the state shown by the chain double-dashed line in FIG. 2, and the lid 2 can be removed from the container 1.

As described above, in the pressure cooker according to the embodiment, the upper handle 8 is provided between the engaging flanges 4 on the outer periphery of the lid 2, and the first moving piece 16 is provided between the upper handle 8 and the peripheral edge of the lid 2. It projects through the hole 2a. The position of the hole 2a from which the first moving piece 16 protrudes is out of the engagement collar 4, and the shape of the lid 2 is simple in the vicinity of the hole 2a without being complicated. Therefore, the lid 2 can be easily molded and manufactured.
