A vent hole 5 for ventilation is provided in the central portion of the top plate 2a of the lid 2, and the through hole 5 can be sealed by a hole sealing member 6 that swings in a seesaw manner.
The vent hole 5 allows the air inside the container to leak to the outside when the lid is closed, and allows the inside and outside of the container to communicate with each other when the lid is opened to easily open and close the lid body 2. It is for this purpose and is conventionally known. However, in the prior art, the ventilation hole is opened and closed by a sliding movement type or dial type hole sealing member, and it is difficult to obtain smooth operability and it is difficult to ensure perfect airtightness. there were.
On the other hand, in the present invention, the through hole 5 has a structure that can be sealed by a hole sealing member 6 that swings in a seesaw manner, so that the communication state and the airtight state of the through hole 5 can be switched. It has a structure that can be easily and smoothly simply by pushing.

In the illustrated example, the hole sealing member 6 has an oval shape in plan view, and shaft portions 6a and 6a project from both sides of the central portion orthogonal to the longitudinal direction. The shaft portion 6a is formed on the top plate 2a. It is engaged with the groove 2b and can swing in a seesaw manner around the shaft 6a.
Further, the top plate 2a is formed with a recess 7, and the hole sealing member 6 is stored in the recess 7. The top surface of the hole sealing member 6 and the top plate 2a are flush with each other. Yes. In this case, the groove 2b is formed at the peripheral edge of the recess 7.

The ventilation through hole 5 is formed on the bottom surface of the recess 7, and a cylindrical body projects from the through hole 5. On the other hand, a guide portion 6b is suspended from one end of the lower surface of the hole sealing member 6, and the through-hole 5 is sealed by inserting the guide portion 6b into the cylinder.
Further, a sealing packing member 8 made of elastic rubber, thermoplastic elastomer or the like is attached to the upper end of the cylindrical body, and when the sealing member 6 is in a closed state, the packing member 8 is sealed. It is comprised so that airtightness may be ensured by closely_contact | adhering to the back surface side of 6. FIG.

  Further, the lower surface on the other end side opposite to the side on which the guide portion 6b of the hole sealing member 6 is provided, that is, the operation side surface is a tapered surface 6c whose thickness gradually decreases from the central portion toward the edge portion. The sufficient rotation angle of the sealing member 6 can be ensured in a small space, and the sealing member 6 can be easily swung, so that the opening / closing operation can be performed smoothly.

  Further, a projection 9a is formed on the outer peripheral edge of the hole sealing member 6 on the side where the guide portion 6b is formed, while a projection 9b is formed on the inner wall surface of the recess 7 corresponding to this projection. In addition, the engagement relationship between the pair of protrusions 9a and 9b makes it possible to make the opening and closing operation of the sealing member 6 moderate, and prevents the sealing member 6 from lifting up and releasing the airtight state without permission. It is configured.

Next, the opening / closing operation of the lid of the sealed storage container having the above configuration will be described.
First, as shown in FIGS. 3 to 4, an object to be stored (not shown) such as food is stored in the container body 1 with the lid 2 opened, and the lid 2 is closed. At this time, as shown in FIG. 5, the sealing member 6 of the lid body 2 is basically in a state of being pushed in until the tapered surface 6c comes into contact with the bottom surface of the recess 7 so that the through hole 5 is in a vented state. To do.
Thereby, the air in the container main body 1 pressurized by the press-fitting of the lid body 2 leaks to the outside through the through holes 5 and maintains an atmospheric pressure state. In addition, the lid 2 can be pushed in smoothly because there is no resistance by compressed air.

  Next, as shown in FIGS. 1 and 2, the sealing member 6 is swung in a seesaw manner, and the guide portion 6 b is inserted into the through hole cylinder and sealed. At the same time, the back surface of the sealing member 6 and the elastic packing member 8 attached to the upper end of the cylinder are brought into close contact with each other, and the airtightness of the through hole 5 is more completely guaranteed. In addition, since the sealing material 4 having elasticity attached to the peripheral edge of the lower surface of the lid 2 and the inner peripheral surface of the opening of the container body 1 are completely in close contact with each other, the airtightness in this portion is reliably ensured. Yes.

  As described above, after storing an object to be stored in an airtight state in which the object is blocked from outside air, the container is refrigerated in a refrigerator or stored at room temperature in a room. During the storage, if the lid 2 is pulled up to open the lid, the lid 2 is slightly lifted due to the elasticity of the sealing material 4, but the inside is kept airtight, so only the volume expansion inside Slightly negative pressure is applied to act to pull back the lid 2. Therefore, a considerably large force is required to open the lid against this negative pressure, and the lid is not opened. In addition, when the container is dropped, the lid is not opened, so that the object to be stored is not scattered.

  Next, when the lid is opened, as shown in FIG. 5, the sealing member 6 is swung in a seesaw manner, the guide portion 6 b inserted into the cylinder of the through hole 5 is pulled out, and the through hole 5 is vented. State. As a result, the inside and outside of the container communicate with each other and an atmospheric pressure state is established, so that the lid 2 can be easily lifted. In addition, when the sealing member 6 is swung by one push, the outer peripheral edge portion of the hole sealing member 6 on the side where the guide portion is formed and the inner wall surface of the concave portion 7 corresponding to the protrusion are engaged with each other. The projections 9a and 9b are formed, and the projection 9a gets over the projection 9b, so that the opening and closing operation of the sealing member 6 can be made moderate.

In the above description, as shown in FIG. 5, the case where the through-hole 5 is closed in a vented state is described, but the through-hole 5 is sealed as shown in FIGS. 3 to 4. The lid can also be closed.
In this case, the air in the container pressurized by pushing the lid 2 is leaked to the outside through the through hole 5. That is, since the hole sealing member 6 is set so as to be swingable in a seesaw manner around the shaft portion 6a, when the pressurized air acts from the inside, the inserted guide portion 6b is pushed up to the outside through the through hole 5. It leaks and the inside becomes an atmospheric pressure state. Further, since the pressure of the pressurized air is slight and the engagement of the protrusions 9a and 9b is not released, the hole sealing member 6 returns to its original position under its own weight after the atmospheric pressure is reached. It will return and keep airtight.
The subsequent operations for storing the container and opening the lid are as described above.

It is sectional drawing which shows embodiment of this invention. FIG. 2 is a perspective view of FIG. 1. It is sectional drawing which shows an open state. FIG. 4 is a perspective view of FIG. 3. It is sectional drawing which shows the state which act | operated the sealing member.
