[0012]

In this embodiment, the present invention is applied to a food storage container as shown in FIG.

The container body 1 is formed of a heat-resistant polypropylene resin, and a lid 4 fitted into the upper opening 3 of the container body 1.
Is formed of polycarbonate having excellent heat resistance and elasticity, and a silicone packing 16 is provided at a fitting portion 15 of the lid 4 with the container body 1 so that the lid fits into the container body 1 and the upper opening 3 thereof. The tightness of the container 6 made of the body 4 is enhanced.

The cover 4 is provided with a valve mechanism a, a whistle blowing mechanism b, and a rotating body 13. The valve mechanism a has an exhaust hole 7 for discharging air from the inside of the container body 1, and an exhaust hole on the upper surface side of the exhaust hole 7. A circular vertical wall 26 having the hole 7 as a center is provided, a valve plate 8 made of silicon is placed on the upper surface of the circular vertical wall 26, and the upper surface of the lid 4 is pressed. If the pressure is stopped so that the valve disc 8 is lifted from the vertical wall 26 and the air in the container 6 is discharged, the circular vertical wall 26 is closed by the valve panel 8 and the container 6 from the exhaust hole 7 is closed.
It is configured to prevent air from flowing into the inside. The whistling mechanism b is provided with a circular fitting wall 18 centered on the exhaust hole 7 on the lower surface side of the exhaust hole 7 provided in the lid 4 and the circular fitting wall 18.
A whistle blowing member 17 provided with a whistle blowing hole 9 and a singing mouth 20 is press-fitted to 18 to form an abacus ball-shaped convection chamber 10 between the exhaust hole 7 and the whistle blowing air hole 9. I have. One end of the rotating body 13 is pivotally attached to the lid 4 so as to be able to move up and down, and an operating section for moving the rotating body 13 up and down, and a contacting / separating body 11 for moving the valve disc 8 away from the circular vertical wall 26 toward the pivot base 14 side. 12 and the rotating body 13
When the rotating body 13 is turned down and the rotating body storage recess 19 for accommodating the
The upper surface is flush with the upper surface.

Therefore, if the upper surface of the lid 4 is pressed, the container 6
The inside air passes through the flute blowing vent 9 and the convection chamber 10 from the mouth 20 and is discharged from the gap between the valve disc 8 lifted up through the exhaust hole 7 and the circular vertical wall 26, so that the air A whistling sound is generated with the discharge, and if the pressing is stopped, the inflow of air in the container 6 is blocked by the valve disc 8 and the inside of the container 6 is kept under reduced pressure by the elasticity of the lid 4, so that the container 6 is completely sealed. .

Therefore, the discharge of the air in the container 6 can be confirmed by the whistling sound. For example, the container 6 is repeatedly pressed by the whistling sound until the whistling sound stops.
Can be appropriately pressed to hold the container under reduced pressure, thereby sealing the container.

The whistling member 17 which is press-fitted to the fitting wall portion 18 can be removed and the convection chamber 10 can be cleaned.

In order to open the container 6 held under reduced pressure by discharging the air inside the container 6, it is necessary to return the valve plate 8 from the exhaust hole 7 and return the inside of the container 6 to normal pressure.

There are various means for separating the valve disc 8 from the exhaust hole 7. In this embodiment, the valve disc 8 is provided on the contacting / separating body 11 which can move the valve disc 8 freely from and away from the circular vertical wall 26. Further, the contacting / separating body 11 is provided on the pivoting base 14 side of a rotating body 13 having one end pivotally mounted on the upper part of the exhaust hole 7 so as to be able to undulate, and the operating section 12 is provided on the tip end side of the rotating body 13. The valve panel 8 is separated from the circular vertical wall 26 by operating the operation unit 12 with a finger to raise the rotating body 13.

The operating section 12 is a ring 22 provided on the tip end side of the rotating body 13, and the ring 22 is put up with a finger so as to stand up so that the valve disc 8 can be separated from the circular vertical wall 26. are doing.

When the valve body 8 is placed on the bottom surface of the circular recess 23 having a diameter larger than the diameter of the valve plate 8 and a circular hole 25 smaller than the diameter of the valve plate 8 is mounted, A peripheral locking edge 21 for locking the peripheral edge and a cover member 24 for press-fitting and fixing the upper surface opening of the circular concave portion 23 to prevent the valve disc 8 from coming off from the upper surface opening of the circular concave portion 23. I have.

When the rotary body 13 provided with the contacting / separating body 11 is turned down, the valve disc 8 provided in the contacting / separating body 11 is placed on the circular vertical wall 26 and the peripheral locking edge 21 and the covering member 24 are provided. The size of the circular vertical wall 26 is located approximately in the middle of the peripheral locking edge 21 of the circular hole.
The diameter is set smaller than the diameter of the circular hole 25 and smaller than that of the circular hole 25 so that it can be penetrated.

Accordingly, by pressing the bottom portion 2 of the container body 1 or the upper surface portion 5 of the container body 1, the container body 1 is pressed.
The air inside lifts the valve disc 8, and the air flows outside the gap between the circular vertical wall 26 and the lifted valve disc 8 via the exhaust hole 7 and the gap between the peripheral locking edge 21 and the circular vertical wall 26. When the pressing is stopped, the valve disc 8 returns to the circular vertical wall 26, and the elastic force of the container 6 and the lid 4 causes the air to enter the container 6 in a direction in which the air is introduced through the exhaust hole 7. Is added, and the valve plate 8 adheres to the circular vertical wall 26 by the pressure to prevent the inflow of air from the outside of the container 6 and to reduce the pressure inside the container 6,
The lid 4 closely contacts the container 6 by the pressure, and the container 6 is completely sealed.

When the rotating body 13 of the container 6 sealed in a reduced pressure in this manner is raised by putting a finger on the ring 22, the peripheral edge of the valve panel 8 is locked by the peripheral locking edge 21. 8
Is pulled away from the circular vertical wall 26 as the rotating body 13 rises, air can flow into the container 6 and the pressure in the container 6 can be reduced to normal pressure, and the rotating body 13 itself raises the lid. When the container 6 is opened, the rotating body 13 is used.
The container can be easily opened like a pull-top can by simply lifting the ring 22 with a finger and lifting it up.

Further, the rotating body 13 is constructed so as to be able to raise the rotating body 13 by 90 degrees or more, so that the valve disc 8 can be kept constantly separated from the exhaust hole 7, while the rotating body 13 is turned down with the rotating body 13 turned down. The rib 27 for locking and fixing the undulation is the lid 4
It is provided in.

Therefore, a very convenient sealed container in which the lid 4 of the sealed container 6 can be opened very easily like opening a pull-top can. Further, in a sealed container having a conventional valve mechanism, when the container 6 is heated, the air in the container 6 expands, and when the heated container 6 is cooled, the valve mechanism operates to make the inside of the container 6 a high vacuum state. Since the deformable container 6 is extremely deformed, it cannot be heated by putting the sealed container in a microwave oven as it is. However, in the sealed container of the present invention, the rotating body 13 is greatly caused. As a result, the valve disc 8 can be kept constantly separated from the exhaust hole 7, so that it can be heated with a microwave oven or the like while the lid is kept.

[0027]

Since the present invention is constructed as described above, the discharge of the air in the sealed container to the outside can be confirmed by the whistle sound by the whistle sound mechanism provided at the exhaust port, and the whistle sound is used as a guide. This is a very easy-to-use sealed container that can press the container appropriately to reduce the pressure and seal the container.

Further, since an up-and-down rotatable member capable of moving the valve plate freely through the exhaust hole is provided, it is very excellent that the depressurized container can be opened with one touch like a pull-top can. It becomes a sealed container.
