[The problem to be solved by the creation]

However, when the storage container closed by the function of the hermetic container is to be opened when the contents are used, a large force is necessary to release the sealed state (Patent Document 1 and Fig. 5).

In addition, it has also been developed to have a hermetic release mechanism for releasing the above-mentioned hermetic state in advance, but the conventional hermetic release mechanism has a complicated structure that occupies a large portion of the lid, which causes the storage container to become heavy. In addition, most of the conventional airtight release mechanisms are provided in the central part of the lid. In the above cases, the beauty of the storage container may be impaired.

On the other hand, if the above-mentioned airtight release mechanism is not provided, only when the lid is provided with a sealing material, when the storage container is to be sealed, the lid will rebound due to the pressure of the air inside the container, and the sealing operation is not easy. [Means used to solve the problem]

Therefore, as a means to solve the above-mentioned problems, the sealing structure for a storage container related to the present invention is a structure that forms a lid for closing the opening of the container formed in the storage container, and includes a soft gasket that closes the opening. , Mounted on the outer peripheral surface of the lower half of the cover embedded in the opening, and formed by extending outward relative to the outer peripheral surface; degassing holes formed through the thickness direction of the gasket; and a bulge in the lower half The outer peripheral surface of the fitting portion is formed at a position directly above the degassing hole. When the lower half fitting portion is fitted into the opening and closes the opening, the gasket is bent by the pressing force from the inner wall surface of the container, and The degassing hole is covered on the protruding part and then closed.

The protruding portion may be formed as a point-shaped protrusion having a size that closes the degassing hole, and may also be formed in a ring shape across the entire periphery of the lower half-insertion portion. The protruding part can also be integrally formed with the cover, and after the cover is formed, it can also be formed by installing raw materials such as silicone, elastomer, or synthetic resin by welding or the like.

The gasket is made of silicone, elastomer, or synthetic resin, which has high gas barrier properties and is easily deformed.

The degassing hole may be of a size that can be seen visually, but it is preferable to form an extremely small hole. In addition, although one degassing hole needs to be formed in the gasket to realize a sealed structure for the storage container, it does not matter if two or more are provided.

When inserting the lid into the container of the storage container to airtightly, hold the lid near the area where the degassing hole is formed, apply an upward force and insert it, and then exhaust the air inside the container from the degassing hole. The cover is inserted into the opening of the container. Thereby, the rebound of the cover due to the air in the container can be suppressed, and the insertion operation of the cover can be easily completed.

Since the gasket is formed of a soft raw material, the degassing hole is closed by the bulge and only the edge of the lid in the state after the storage container is closed is pushed up, and the gasket around the degassing hole can be deformed. The closed state of the degassing hole due to the bulge can be released by the deformation of the gasket around the degassing hole. Once the closed state of the degassing hole is released, external air can be introduced from the outside of the storage container to the inside of the container, and the lid can be easily removed from the container.

In addition, it may be provided with a lid formed of the above-mentioned sealed structure for the storage container. In addition, this creation is a storage container provided with the above-mentioned lid formed by the above-mentioned sealing structure for the storage container. [Creation effect]

According to this creation, when the cover is inserted into the container of the storage container, the rebound of the air in the container can be suppressed. Thereby, it is easy to complete the insertion operation of the cover.

According to this creation, only the edge of the lid of the sealed storage container is pushed up to release the sealed state, and the lid can be removed with a slight force.

Hereinafter, while referring to the figure, we will explain in detail the implementation related to this creation. In addition, in this specification and the drawings, for constituent elements having substantially the same functional configuration, the same symbols are assigned to omit repeated descriptions.

FIG. 1 shows a front view of the storage container 1, and FIG. 2 shows a plan view of the storage container 1. In this embodiment, the storage container 1 is constituted by a container 2 and a lid 3 that closes the upper end of the container 2. 3 and 4 show a left side view and a front view of the lid 3 removed from the container 2.

The cover 3 is shown in FIGS. 3 and 4, and has an upper half 4 formed by a peripheral edge portion extending outward in the peripheral direction, and a lower half insertion portion 5 formed by protruding downward from the upper half 4. On the peripheral surface of the lower half-insertion part 5, a groove 6 is provided across the entire circumference, and a gasket 7 made of a soft silicon collagen material is embedded in the groove 6. The gasket 7 is held in the groove 6 in a state of extending outward from the outer peripheral surface of the lower half-insertion part 5. The outer shape of the gasket 7 is a size slightly larger than the size of the opening 2a of the container 2.

According to this embodiment, on the left side of the gasket 7, as shown in FIG. 5, a degassing hole 8 formed as a small hole penetrating the gasket 7 in the thickness direction is formed.

In addition, on the peripheral surface of the lower half-insertion part 5 and at a position directly above the degassing hole 8, a protuberance 9 is formed across the entire periphery of the outer surface of the lower half-insertion part 5, and the degassing hole 8 formed in the gasket 7 forms a storage container. Airtight structure 100.

Next, the function of the sealing structure 100 for a storage container is demonstrated. As shown in Figures 6 and 7, when the lower half insertion portion 5 is inserted into the opening 2a of the container 2 when the container 2 is closed, the outer edge end of the gasket 7 is in close contact with the inner wall surface 2b of the container 2 while receiving the pushing force. With this pressing force, the gasket 7 is bent in the direction of the upper half 4 of the cover 3. As the gasket 7 is bent, the degassing hole 8 is also pushed upward and pushed to the bulge 9. When the degassing hole 8 makes the gasket 7 sufficiently bend, it covers and closes the opening 8a at the upper end while being crimped to the protruding portion 9. FIG. 8 shows an enlarged view of the sealing structure 100 for a storage container in a state where the degassing hole 8 closes the opening 8a by the bulge 9. The degassing hole 8 that closes the opening 8a by the bulge 9 blocks the outside air located outside the gasket 7 from the inside of the container 2 and makes the storage container 1 airtight.

In addition, the deaeration hole 8 provided in the sealing structure 100 for the storage container can suppress the rebound of the lid 3 due to the air in the container 2 when the storage container 1 is sealed with the lid 3, and the insertion operation of the lid 3 can be easily completed. That is, when the lid 3 is inserted into the container 2 of the storage container 1 and closed, the edge of the lid 3 near the degassing hole 8 is formed by holding the edge portion of the lid 3 and bending upwards while pushing and inserting the container. The lid 3 is fitted into the opening 2a of the container 2 while the air in the container 2 is exhausted.

When the sealed storage container 1 is opened, since the gasket 7 is formed of a soft raw material, the degassing hole 8 is closed by the bulge 9 and only the edge of the lid 3 in the closed state of the storage container 1 is pushed up, that is, The bent portion of the gasket 7 around the degassing hole 8 can be deformed in the direction separating from the upper half 4. The closed state of the degassing hole 8 due to the bulge 9 can be released by the deformation of the gasket 7 around the degassing hole 8. Once the closed state of the degas hole 8 is released, external air can be introduced from the outside of the storage container 1 into the interior of the container 2 and the lid 3 can be easily removed from the container 2.
