る。[Problems to be Solved by the Invention] When filling and packaging miso etc. during fermentation, it is preferable to quickly and completely seal it in a hygienic environment to prevent invasion of various bacteria even if it is a little, but when fermentation progresses and gas generation becomes vigorous Since internal pressure is applied to the inside of the container, which leads to deformation and further rupture of the container, a method has been adopted in which a small hole is made in the lid material to prepare for gas generation after days. However, there is little rapid gas generation immediately after filling and packaging, and the pressure inside the container decreases on the contrary when the temperature change in winter is drastic, and if only small holes are provided in the heat-sealed lid material, the outside air will not leave a gap between the cap and the container body Pass through the small hole, and freely enter and leave the container. As a result, dust, disinfectant insecticide, germs, or moisture in the air may enter the container and alter the contents in the container, which is a sanitary problem. Further, the method of mounting the one-way overpressure relief valve on the inside or the outside of the small hole opened in the heat-bonded lid material solves the above problems, but the cost of the one-way overpressure relief valve itself and The cost of the mounting device is considerable, the packaging cost is high, and it is uneconomical.

も僅かで済む密封容器を提供することである。It is an object of the present invention to eliminate the above-mentioned drawbacks, and when filling and packaging miso during fermentation into a plastic container, the lid material is heat-bonded to the main body of the plastic container without a through hole such as a small hole. Completely sealed, when fermentation proceeds and the internal pressure rises due to gas generation, the internal gas is automatically released to the outside to quickly reduce the internal pressure, restore the sealing property, prevent deformation and rupture of the container, and package it. It is an object of the present invention to provide a hermetically sealed container that requires less material, labor and equipment.

ト面と接合してシールを回復する作用をする。According to the present invention, the hermetically sealed container is constructed as follows: a plastic container body having an open upper end, a lid sheet heat-bonded to the top of the side wall of the container body, and the container. A plastic cap that covers the cover sheet and is removably fitted to the upper part of the main body, and at least a part of the surface of the cover sheet facing the opening of the container body has a hole, a hole row, or a longitudinal crack. An opening formed of a disconnection is provided, a release agent is applied to one side or both sides of the opening of the lid sheet, and the release agent coating area around the opening and the opening is covered, and the opening is formed. An adhesive tape is attached over the area on one side of the part where the release agent is not applied. Therefore, in the sealed container of the present invention, when the internal pressure of the container exceeds a predetermined overpressure value, the adhesive tape that has been pressure-bonded to the release agent application surface is lifted from the lid sheet, and when the internal overpressure is removed, the release agent is again applied. It acts to restore the seal by joining with the lid sheet surface through.

を用いることができる。FIG. 3 is a schematic view showing a manufacturing process of the sealed container of the present invention. In this figure, 31 is a lid sheet tape 32.
Is a supply spool for supplying. For the lid sheet tape, for example, aluminum vapor-deposited paper, aluminum foil, polypropylene, polyethylene can be used. The lid sheet tape 32 is formed by using a cutter 33.
The long hole, that is, the opening 34 is cut in the longitudinal direction.
Reference numeral 35 is a track coated with a release agent, for example, a silicone-based coating agent along the peripheral edge of the opening 34 of the lid sheet tape 32. 37 is an adhesive tape supply spool from which the adhesive tape 38 guides the guide roller 3
It is applied so as to cover the silicone coating track and the opening 34 of the lid sheet tape 32 via 9 and to be directly bonded to the lid sheet tape on one side. Note that the release agent 35
Can be printed on the sheet tape in advance, or can be sprayed from the coating roller or the spray nozzle after forming the opening. It should be noted that the release agent 35 must have a property that the adhesive tape is easily lifted from the lid surface coated with the release agent when an overpressure is applied, and returns to the original position and adheres when the overpressure is released. The silicone-based coating agent is best suited to this property. Then, a corner cut 40 for dividing each lid is appropriately cut, drawn out by a feeding roller (not shown) according to the size of the container body, cut by a cutter 41, and taken out as a lid sheet 42. The lid sheet 42 thus taken out is heat-bonded to the top of the side wall of the upper end 43 of the container body 46 by a conventional means such as heat sealing means. Of course, means such as laser welding or ultrasonic welding can be used for this adhesion depending on the material used.

も楕円孔でも長孔でもよい。In this case, the case where the raw miso 47 during fermentation is filled in the sealed container body will be described. FIGS. 4 and 5 show a state in which the container sheet 46 is filled with miso and then the lid sheet 42 is heat-bonded to be completely sealed.
In the case where the miso has not been filled for a long time, the upper space of the miso is sealed while being filled with the outside air. The adhesive tape 38 is directly adhered to the lid sheet 42 in the area where the release agent is not applied, and the lid sheet 42 is attached to the area where the release agent is applied in other areas via the adhesive layer 45. That is, the lid sheet 4
When the outside air pressure on the outside of 2 is higher than the inside pressure of the void portion of the sealed container, the adhesive tape 38 is pressed toward the lid sheet 42 by the outside air pressure, and the opening 34 is completely covered by the adhesive tape and the release agent coating layer. It is sealed. When the fermentation gas such as carbon dioxide accumulates and the internal gas pressure increases for a period after filling the miso, and the overpressure occurs, the adhesive tape 38 is lifted from the application area of the release agent 35 as shown in FIG. Until the overpressure of the internal gas is eliminated, the internal gas in the closed container flows out through the opening 34, between the adhesive tape and the release agent layer film, as shown by the arrow. When a liquid type adhesive having a slightly low adhesive strength is used as the release agent used, the release agent layer may be split into two, and the gas may flow out through the gap between the layers. When the internal pressure is released by the outflow of this gas, the pressure-sensitive adhesive tape is lowered and the peeled release agent layer film is united again to close the opening 34 and the sealing function is restored. 7-9 show various embodiments of a lid sheet structure comprising a lid sheet 42, a coated release layer and an adhesive tape applied. In these figures, the width of the release layer region applied on the lid sheet 42 is indicated by 35, and the width of the adhesive tape is indicated by 38. The opening 34 is formed by a row of holes in FIG. 7, is formed by a row of holes in FIG. 8, and is formed by a single tear line in FIG. The holes may of course be circular holes, elliptical holes or elongated holes.

The container can be manufactured inexpensively with simple equipment, deformation of the container can be prevented, and deterioration of the contents can be reliably prevented.
