Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air valve for pressurizing air into a container a in order to dispense a small amount of liquid b in the container a from a spout c, as shown in FIG. 4, for example.

Conventionally, for this purpose, it has been known to press air into the container by expanding and contracting a hollow rubber gripped ball, but in these, the position of the gripped ball with respect to the spout c is restricted to a fixed position. Because of this, there was a certain direction when using it, which sometimes made it inconvenient to use.

The present invention improves this by making it possible to freely change the position of the gripped ball, making it easier to expand and contract the gripped ball from any direction, making it easier to dispense, and the movable type also prevents liquid leakage. The purpose of this is to prevent any inconvenience from occurring, to make processing and assembly in manufacturing extremely easy, and to obtain it at a low price. A hollow grip ball 4 made of rubber that communicates with the air passage 2 is connected through the air passage 2, and a normally closed deaeration valve 5 that can be opened at any time is provided in the middle of the air passage 2, which communicates with the other end of the air passage 2. A cylindrical tube 6 is fixed to the valve body 1, and a hollow shaft tube 7 is rotatably inserted into the tube 6.
A packing 8 is attached to a part of the joint between the hollow shaft tube 6 and the tube 6, one end of the hollow shaft tube 7 is made to protrude from the tube 6, and the protruding end 7a is immovably connected to the tubular fixing fitting 9. It consists of

Embodiments of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a valve body, which has a ventilation passage 2 with one end as a blind hole, and a check valve 3 at the open end of the ventilation passage 2.
The rubber grip ball 4 communicates with the valve body 1 through
It was tied to the end of the. The check valve 3 is formed of a rubber cylindrical tube with one end closed, as shown in FIG. A hole 11 is provided, and when the gripped ball 4 contracts, air flows from the through hole 10 to the notch 11.
is pushed open and flows into the ventilation passage 2 of the valve body 1. However, if the air flows backwards, the pressure will cause the air to flow into the air passage 2 of the valve body 1.
1 is compressed and occluded, making it impossible for air to flow backwards. The gripping ball 4 is squeezed and contracted to send air into the valve body 1, and when the gripping pressure is released, it returns to its spherical shape due to the elasticity of the rubber, and at this time, air is released from the one-way valve 12 at the other end. The suction into the grip ball is no different from the conventional one. In the middle of the valve body 1 is a degassing valve 5 having the following structure.
will be established. That is, as shown in FIG. 3 in the valve body 1, the head 15a of the shaft piece 15, which is press-fitted into the bottom of the cylindrical piece 13 having a hole 14 at the bottom and loosely penetrated through the hole 14, is inserted through the O-ring 16. Tube piece 1
3, the tip of the ring piece 15 is press-fitted into the knob piece 17, and an elastic spring 18 is interposed between the knob piece 17 and the bottom inner surface of the cylindrical piece 13. By forcing the head piece 15a of the shaft piece 15 outward, the hole 14 at the bottom of the cylinder piece 13 is always closed, and by pressing the knob piece 17 against the spring, the shaft piece 15 is closed to the first position.
As shown in the figure, the head piece 15a is pressed down to release the air in the ventilation passage 2 of the valve body 1 to the outside. Note that a notch 13a is provided on the upper edge of the cylinder piece 13 to prevent the air from becoming impossible to degas due to the inner surface contacting the upper end of the cylinder piece 13 when the knob piece 17 is pushed down. The air was sufficiently degassed from the notch 13a. A cylindrical tube 6 is press-fitted and fixed to the other end of the valve body 1, and a hollow shaft tube 7 is rotatably inserted therein, and one end thereof is extended to protrude from the cylindrical tube 6, and the protruding end 7a is It is inserted into the through hole 19 of the tubular fixing fastening fitting 9 having a through hole 19 and is immovably connected as one body,
A packing 8 is attached to a part of the joint between the cylinder tube 6 and the shaft tube 7 to prevent air leakage from the fitting gap between the two. In the illustrated example, the cylindrical tube 6 has a bottom and a through hole 6a is provided therein, and the protruding portion 7a of the shaft tube 7 is formed to have a small diameter, and by inserting this into the through hole 6a and causing it to protrude, the cylindrical tube 6 is closed. (6) and the barrel 7 are engaged with each other by abutting the bottom of the barrel 6 and the large diameter part of the barrel 7, and the packing 8 is interposed between the engaging portions. Other suitable means may be adopted for the structure for preventing the tube 6 and the shaft tube 7 from coming off. In addition, the fixing fitting 9 is attached to a predetermined container so that it can be attached and detached when the valve of the present invention is used. Tube 9
b, and the valve of the present invention is installed by screwing the threaded tube 9b into nuts 20 etc. buried in the mounting position of the container etc. in advance, but the form of the fixing fitting 9 is arbitrary and the required is the ventilation passage 2 of the valve body 1
Any material may be used as long as it has a through hole 9c communicating with the hollow hole of the shaft tube 7 and can be easily attached to and detached from the container at a predetermined position.

In the above configuration, when the air valve of the present invention is fastened and fixed in a predetermined position using the fastening fitting 9, the shaft tube 7 is fixed integrally with the fastening fitting 9; Since it can rotate in any direction around the center, the rubber grip ball 4 can freely change its direction together with the valve body 1, which is integral with the shaft tube 7. For example, as shown in FIGS. 4 and 5, When the valve of the present invention is attached and fixed to a lid d attached to a container a, the position of the gripping ball 4 can be rotated from any direction, and the contraction of the gripping ball 4 releases the air inside the ball. is fed into the container a from the ventilation path 2 through the shaft tube 7 and the through hole 9c of the binding fitting 9, and due to the pressurization, the liquid in the container a is poured out from the spout c through the liquid pipe e. The liquid can be drawn out continuously by repeatedly squeezing the grip ball 4, and if necessary, the pressure inside the container a can be removed by using the knob 1 of the degassing valve 5.
If 7 is pressed, the pressurized air in the container will flow in the opposite direction to the air supply and can escape from the deaeration valve 5 to the outside.

In this way, according to the present invention, the valve body 1 can freely rotate due to the rotation of the cylinder tube 6 that is integrated with the valve body 1 and the shaft tube 7 that is inserted through this tube and fixed to the container side. Since the grip ball 4 can be moved freely, it can be gripped freely by changing the position of the grip ball 4, and the liquid can be taken out from any direction.Also, regardless of the movable type, the gap between the members is airtight and air leak-proof. Moreover, manufacturing, processing and assembly are easy and reliable without any inconvenience caused by this.
