This type of container maintains airtightness by tightening the container body and lid to isolate it from the outside air, but if you seal it with hot items inside, the internal pressure of the container body will decrease when the contents cool down. As a result, it often happened that the lid would not open even after the tightening was released.

In order to solve the above-mentioned problems of the prior art, the present invention has been developed by integrally molding a receiving part that protrudes along the opposite side of the lid that closes the opening of the box-shaped container body in a sealed container, and inserting a hole in the bearing part into the hole at both ends. A bent latch is rotatably attached, a protruding receiver for latching the latch is integrally molded on the edge corresponding to the opposite side of the container body, and an endless protrusion is formed on the inner surface of the lid to fit within the container opening. An endless recessed groove is formed on the outer periphery of the endless protrusion to accommodate the packing, and a ventilation hole that reaches the outer surface of the lid is passed through the lateral side of the endless recessed groove, and when the lid is closed, the above-mentioned passage is formed. The pores are closed and the ventilation holes are opened when the lid is opened.

Examples thereof will be described below with reference to the drawings. 1st
In Figures 1 to 4, 1 is a box-shaped container made of synthetic resin or ceramics and has an arbitrary shape such as square or circular flat surface, 2 is a lid made of synthetic resin that closes the opening of container 1, and 3 is a lid. a bearing part that is integrally molded and extends along the edges corresponding to the two opposing sides or the four opposing sides of 2;
4 is a latch provided on the bearing part 3, which has a diameter of 3 mm.
Both ends of the metal rod are bent inwardly to form a square or square shape, and the ends 41, 41 are attached to the bearing hole 31 so as to be vertically movable. Reference numeral 5 denotes an overhang receiving portion for latching the latch 4, which is integrally molded on the edges corresponding to the two opposing sides or the four opposing sides of the container body 1.

る。 Reference numeral 6 indicates an endless protrusion formed on the inner surface of the lid 2 so as to fit internally into the opening of the container body, and reference numeral 7 indicates an endless groove formed along the outer periphery of the endless protrusion 6. It accommodates an elastic packing 8 made of synthetic resin or the like that allows for. Reference numeral 9 denotes a ventilation groove formed from the inside of the container body to a horizontal side portion 91 intersecting the groove 7. The ventilation groove 9 has a width w of 0.5 to 2.0 mm and a depth t of 0.5.
Set to ~2.0mm. Figures 5 to 7 show the horizontal side of the concave groove 9.
A ventilation hole 90 is provided extending from the ventilation groove formed halfway through the lid until it reaches the outer surface of the lid. And as a means to open and close the ventilation hole,
In FIGS. 6 and 7, an elastic packing 8 housed in the groove 7 is used. In other words, Fig. 6 shows that when the lid is opened,
The upper surface 81 of the packing 8 is separated from the lower end surface of the vent hole 90 due to its elastic restoring force, so that the inside and outside of the container body are communicated with each other. When the lid is closed as shown in FIG. 7, the upper surface 81 of the gasket acts as a plug and comes into close contact with the lower end surface of the vent hole 90, so the vent hole is closed and air circulation inside and outside the container body is blocked. Ru. In addition, FIG. 8 shows another embodiment of the means for closing the vent hole 90, in which the vent hole 90 is a screw hole, and the blocking plug is placed on the gasket 82 instead of the upper surface 8' of the gasket.
The ventilation hole 90 may be opened and closed by a screw plug 8'' with a
0 shows yet another embodiment of the closure means of hole 90.
1 is inserted and fixed into a vent hole 90, and is opened and closed by a valve 910 connected to the valve seat with a thin band 902.
図中１１は、容器体開口縁面に設けた山形の突
条で、閉蓋時気密性を増大させるために、パツキ
ン８に対峙させてある。 In the figure, reference numeral 11 denotes a chevron-shaped protrusion provided on the edge of the opening of the container body, which faces the gasket 8 in order to increase airtightness when the lid is closed.
本考案は上記の構成であるから、蓋２を閉じて
掛け金４を掛けると、その締付力によつてパツキ

とはない。
Since the present invention has the above-described structure, when the lid 2 is closed and the latch 4 is applied, the gasket 8 is compressed and deformed by the tightening force to seal the opening of the container body, and at the same time, the gasket 8 also closes the ventilation hole 90. It comes into pressure contact with the lower end surface of the vent hole and acts as a blockage plug, completely blocking the flow of air inside and outside the container body. Therefore, the container body 1 is kept airtight, and moisture such as liquid inside the container body 1 does not leak to the outside.
しかも、該通気孔９０を掛け金４の締付力が最
も大きく作用する部位に設けることにより、その
水密効果はより増大する。 Moreover, by providing the ventilation hole 90 at a location where the tightening force of the latch 4 is greatest, the watertight effect is further enhanced.
そして掛け金４の締付けを解除した場合、容器
体内が減圧状態になつていても、パツキン８が弾

となるねじ栓８″をゆるめることによつて、たて
溝８２を通じて通気孔が開通して空気の流通が確
保され、容器内外が連通して気圧が等しくなるの
で、蓋２は簡単にあけることができる。 When the latch 4 is released, the gasket 8 immediately separates from the lower end surface of the vent hole 90 due to its elastic restoring force, even if the inside of the container is in a reduced pressure state, or when the latch 4 is released, the gasket 8 immediately separates from the lower end surface of the vent hole 90. By loosening the screw stopper 8'', a vent hole opens through the vertical groove 82 , ensuring air circulation, communicating the inside and outside of the container, and equalizing the air pressure, so the lid 2 can be opened easily. Can be done.
さらに、通気孔９０は比較的細い溝であるか
ら、閉塞時はパツキン８の圧縮で閉塞されるとと
もに、しかも通気孔９０の下端面は凹溝７の横辺
部９１より若干低く成形されているだけであるか
ら、パツキン８との圧接が確実である。 Furthermore, since the ventilation hole 90 is a relatively narrow groove, it is closed by the compression of the gasket 8 when it is closed, and the lower end surface of the ventilation hole 90 is formed slightly lower than the horizontal side part 91 of the groove 7. Therefore, the pressure contact with the gasket 8 is reliable.
以上のように本考案の密封容器は、熱いものを
入れて直ぐに蓋をしても、あとで蓋を取るとき蓋
があかなくて困るということがないもので、弁当
箱、おかず入等に実施して実用的効果がある。 As described above, the sealed container of the present invention can be used for lunch boxes, side dish containers, etc. even if you put hot food in it and put the lid on it immediately, you will not have to worry about the lid not opening when you take it off later. It has practical effects.
