Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a push button type ejection container.

"Problems to be solved by the conventional technology and device" Conventionally, there is a so-called aerosol spray in which a cylinder of CFC gas is installed inside and the liquid in the container is sprayed by the gas pressure. Since the CFC gas released to the air is not easily decomposed and rises to an ultrahigh level to destroy the ozone layer, a CFC-free gas is strongly desired. Also, by providing an air pump,
There are some that supply compressed air into the container, but in this case,
It is very troublesome to operate the air pump many times.

The present invention is intended to solve such a problem.

"Means for Solving the Problem" The present invention is directed to a small diameter fixed cylinder 3 at the mouth 2 of the container body 1.
, A suction valve 4 is provided at the lower end of the fixed cylinder, a suction pipe 5 is hung from the lower end, and a large diameter guide tube 6 of the fixed cylinder 3 is provided. A large-diameter movable cylinder 7 is rotatably and vertically movable inside, and a direction changing mechanism 8 for converting the rotational movement of the movable cylinder into a vertical movement is provided between the movable cylinder and the guide vertical cylinder 6, and the inside of the fixed cylinder 3 is provided. A small diameter annular piston 9 and a large diameter annular piston 10 slidably fitted in the movable cylinder 7,
A large-diameter annular piston that connects both annular pistons with a flow pipe 11.
An aerosol valve in which a pressurizing valve 12 is provided inside 10, a spring 13 is installed inside the guide vertical cylinder 6 to urge the large-diameter annular piston 10 upward, and a stem 14 is projected upward at the upper end of the movable cylinder 7.
15 is provided, and a push button 16 having a nozzle 17 is fitted and connected to the stem 14 thereof.

The mode of jetting the liquid is appropriately selected depending on the form of the nozzle 17, such as mist, liquid, or bubbles.

"Operation" As described above, the liquid is stored in the container body 1 for use. When the jet of the liquid is obtained, first, the movable cylinder 7 is manually rotated.

Due to this rotation, the direction changing mechanism 8 works to cause the movable cylinder 7 to move up and down, which causes the small diameter annular piston 9 to move up and down in the fixed cylinder 3.

When the small-diameter annular piston 9 descends, the fixed cylinder 3
The liquid in the flow path pipe 11 is pressurized, the pressurized liquid flows into the movable cylinder 7 through the pressurizing valve 12, and the large-diameter annular piston 10 is lowered against the spring 13. The lowering of the large-diameter annular piston 10 is due to the fact that the pressure receiving area is larger than that of the small-diameter annular piston 9, and the small-diameter annular piston 9 also follows this. Thus, the pressurized liquid that has flowed into the movable cylinder 7 is closed by the pressure valve 12 and the large-diameter annular piston 10.
The liquid pressure is maintained by the elasticity of the spring 13 that presses the.

Further, when the small-diameter annular piston 9 rises, the fixed cylinder 3 and the inside of the flow passage pipe 11 are negatively pressured, and the liquid of the container body 1 flows into the inside through the suction pipe 5 and the suction valve 4.

Next, when the push button 16 is pushed down, the stem 14 descends and the aerosol valve 15 opens, and the pressurized liquid in the movable cylinder 7 passes through the aerosol valve 15 and the stem 14 and the nozzle 17 of the push button 16 is pushed.
Gushes from. When the push button 16 is released, the aerosol valve 15 closes and the push button 16 returns.

"Examples" The drawings are made of synthetic resin and are sprayed.

The illustrated one has a screw cylinder 18 at the mouth 2 of the container body 1 having a bottomed cylindrical shape.
A fixed cylinder 3 having a small diameter is integrally hung from the screw cylinder into the container body 1, and a large-diameter guide vertical tube 6 is integrally protruded upward from the screw cylinder. In the figure, 19 is packing.

A suction valve 4 is provided at the lower end of the fixed cylinder 3, a suction pipe 5 is hung from the lower end thereof, and the lower end of the suction pipe is extended to the bottom of the container body 1. 29 in the figure
Is a vent for introducing outside air into the container body 1.

A large-diameter movable cylinder 7 is rotatably and vertically movable inside the guide vertical tube 6, and a direction changing mechanism 8 for converting the rotational movement of the movable cylinder into vertical movement is provided between the two.

The direction changing mechanism 8 has an endless continuous sawtooth-shaped guide groove 20 formed on the outer periphery of the movable cylinder 7, a pair of notches 21 and 21 provided at the upper end of the guide shaft 6, and balls 22 and 2 are rotated in the notches. The support cylinder 23 is freely supported and is provided on the outer periphery of the upper part of the guide vertical cylinder 6.
To prevent the ball from coming off, and
2 is engaged with the saw-tooth guide groove 20, and the movable cylinder 6 is rotated to slide the saw-tooth guide groove 20 with respect to the balls 22, 22 in a fixed position.
I am trying to convert the rotational motion of the to the vertical motion.

Further, the movable cylinder 7 is provided with teeth 23 on the outer circumference of the upper end, and an outer cylinder 25 having teeth 24 formed on the inner circumference of the upper end is provided on the teeth.
Are engaged and connected.

The external cylinder 25 covers the movable cylinder 7 and the guide vertical cylinder 6, and the rotation of the external cylinder 25 allows the movable cylinder 7 to rotate. The movable cylinder 7 may be directly rotated without using the exterior cylinder 25.

A small-diameter annular piston 9 is provided in the fixed cylinder 3, and
A large-diameter annular piston 10 is slidably fitted in the movable cylinder 7, and both annular pistons are connected in a flow passage pipe 11. For the connection, fitting small cylinders 26 and 27 protruding from both annular pistons are used, and both ends of the flow path pipe 11 are fitted to the fitting small cylinders. Thus, the spring 13 is installed in the guide vertical cylinder 6 to urge the large-diameter annular piston 10 upward.

An aerosol valve 15 having a stem 14 protruding upward is watertightly fitted and fixed to the inside of the upper end of the movable cylinder 7, and a push button 16 is fitted and connected to the upper end of the stem 14.

The push button 16 is provided with a nozzle 17 for spraying which communicates with the stem 14 on the front surface.

Further, a cap 28 is covered on the outside of the push button 16, and the lower end of the cap is detachably fitted to the upper end of the outer casing 25.

[Advantage of Device] According to the present invention, liquid can be ejected only manually without using CFC gas, and pollution by CFC gas can be eliminated. Further, since the liquid is directly pressurized by the rotating operation of the movable cylinder 7 and the pressurized state is maintained to eject the liquid, a troublesome operation like that having an air pump is not required, and the operation is simple and easy. You can
A stable and accurate ejection can be obtained.
