The valve mechanism 4 has a valve mounting hole 3 formed at the center of the bottom of the elevating guide tube 16, and a plurality of vent holes 2 formed around the valve mounting hole 3. a is formed so as to communicate with the inside. And this valve mounting hole 3
The mounting rod 5 hanging from the valve disc 6 is loosely fitted so as not to come off when it rises. The valve disc 6 employs a sucker-type valve disc 6 whose thickness becomes gradually thinner toward the periphery, and a push rod body 15 suspended from a pressing disc body 14 is disposed on the center of the valve disc 6. When the pressing plate 14 slightly protruding from the upper opening of the lifting guide cylinder 16 is pressed to the stopper step 17, the pressure plate 14 is disposed so as to be able to move up and down inside the lifting guide cylinder 16.
Is configured to be able to be turned upward to switch the ventilation hole 2 to the ventilation state.

When formed in this manner, the valve is opened with one touch simply by pressing the pressing plate 14 with a fingertip, and a very easy-to-use decompression container is obtained.

In addition, at the time of absorption, a hand-push type vacuum pump b is applied to the pump fitting portion 18 and the handle 8 is moved up and down to suck out air in the container a. The illustrated hand-push type vacuum pump b is as follows. 1 shows an embodiment having a simple configuration.

The hand-push type vacuum pump b is shown as a case in which a hand-push pump type is adopted, and a piston rod 9 provided with a handle 8 is reciprocated and pushed against the pump cylinder 7 to reciprocate.

〔The invention's effect〕

According to the present invention, foods and pickles to be stored are stored in a small-sized container with a valve, which is compactly designed from the configuration described above, and the inside of the container is depressurized using a manual or powered vacuum pump. Small containers keep the decompressed state as they are, so they can be stored in the refrigerator for a long time to store food, and if the container is used as an instant pickle container, instant pickles can be easily made by decompression. it can.

In addition, in the present invention, the valve mechanism is provided with an elevating guide cylinder portion, and a pressing plate body having a push rod body having a diameter smaller than the surface of the finger is vertically provided at the upper opening of the guide cylinder portion so as to be vertically movable. When the pressing plate is pressed down with a finger, the pressing rod presses the central portion of the valve plate to make the ventilation holes ventilated, and when a negative pressure is applied to the valve mechanism by a vacuum pump. Since the air in the container is discharged through the valve mechanism through the gap between the upper opening edge of the elevating guide cylinder and the pressing plate, the pump can perform the depressurizing operation without any trouble. In addition, when it is desired to release the depressurized state and remove the lid plate, it is possible to simply perform a simple operation of pressing the pressing plate body arranged on the upper part with a finger, and the so-called one-touch operation is used to reduce the depressurized state. Can be released, and the valve panel is located at the bottom of the pump cylinder. The valve disc is not covered, so the valve disc is not exposed and the appearance is good.In addition, the diameter of the valve disc is thinner than the face of the finger compared to pressing the upper face of the disc directly with a finger. Since the valve disc is pressed by the push rod body, the peripheral surface of the valve disc is well turned up, so that a pressure-reducing container excellent in practicality can be easily released from the reduced pressure with a small pressing force.

Further, since the shape of the elevating guide cylinder is configured such that the pump cylinder of the vacuum pump can be in contact with the communicating cylinder, the lower end opening of the pump cylinder of the vacuum pump is simply provided by the elevating guide cylinder. It is an excellent decompression container that can be decompressed simply by applying pressure to the part so as to cover it from above.
