Description

[Detailed description of the invention] The present invention relates to an aerosol valve that opens by pressing the stem from the side and tilting the valve.
It is advantageous when used in aerosol products containing highly viscous materials such as fillers. Aerosol valves that open by pressing the stem from the side and tilting have existed for some time, but they are extremely difficult to operate and require a large amount of force to open the valve, and when the content is high viscosity, the amount of ejection is small. Therefore, it was not possible to obtain a sufficient amount of the contents in a short period of time according to the purpose of use. That is, in the conventionally known inclined opening type aerosol valve, as shown in FIG. Stem 3 in the center of
was inserted closely. This stem 3 has a method in which the flange portion 4 at the lower end is brought into close contact with the lower surface of the gasket 2, and the content introduction hole 5 of the stem 3 is closed by the inner surface of the gasket 2. In order to squirt the contents using this conventionally known method, the aerosol container is inverted and the outward protrusion 6 of the stem 3 is pushed sideways, so that the stem 3 and the outward protrusion 7 of the gasket 2 are connected at two points. It is inclined as shown by the chain line, and by separating one side of the flange portion 4 and one end face of the gasket 2, the contents introduction hole 5 is opened, and the contents are spouted from the outlet path 8. In this method, the content introduction hole 5 is opened in the axial direction of the side surface of the stem 3, and the gasket 2 has a sealing function and a posture control function, so the gasket 2 must be formed thick and strong. When the stem 3 is tilted, the gasket 2 is deformed laterally and compressed in the axial direction.
Opening the contents introduction hole 5 required a large force and the valve could only be opened for a short period of time.
Furthermore, the open area of the content introduction hole 5 was also narrow, making it impossible to discharge a large amount of content in a short period of time.

The present invention eliminates the above-mentioned drawbacks. One end of the stem is inserted into the aerosol container through the mountain cap, and the other end is protruded to the outside, and an intervening device is installed between the protruding side of the stem and the mountain cap. The spring is biased toward the other end of the stem, and this biasing force causes the opening edge of one end of the housing connected to one end of the stem to be located on the inner surface of the mountain cap and to form a flat plate that does not protrude to the outer surface of the mountain cap. A gasket which presses into close contact with the gasket of the stem and normally blocks communication between the outlet path of the stem communicating with the opening edge at one end and the inside of the aerosol container, and which has a spring for controlling the attitude of the stem and a sealing property. Since the spring is formed completely separately, it is possible to use a spring with relatively weak restoring force without making the spring unnecessarily strong, making it easier to open the valve. Since this is done, the open state of the opening edge at one end is made larger when the valve is opened, and a large amount of highly viscous contents can be ejected in a short period of time.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 11 denotes a mountain cap, which is fixed to the upper end of the aerosol container 12 and has a stem 14 slidably inserted into the insertion opening 13 in the center. A housing 15 having a U-shaped cross section is connected and fixed to one end of the stem 14 inserted into the aerosol container 12, and an introduction hole 1 communicates with the inside of the housing 15.
6 is connected to a content outlet passage 17 formed at the center in the axial direction from the outer end. The stem 14 is always urged toward the protruding side by an engaging protrusion 18 provided on the protruding side from the mountain cap 11 and a coiled protrusion 19 interposed between the mountain caps 11. Then press the opening edge 21 at one end of the housing 15 against the gasket 20 located on the inner side of the aerosol container 12 of the mountain cap 11, and
5, the introduction hole 16, the outlet path 17, etc. are cut off. The gasket 20 is formed into a flat plate shape and is located on the inner surface of the mountain cap 11 so as not to protrude to the outer surface.

In the structure as described above, the sealing property is maintained by pressing the opening edge 21 at one end of the housing 15 against the gasket 20.
Even if the restoring force of the spring 19 is weak, it is possible to maintain sufficient airtightness, and by using the spring 19 with a weak restoring force, it is easy to press and tilt the stem 14 from the side, and the force of the fingers is reduced. Since the high viscosity contents can be ejected continuously for a long period of time and the inclination angle of the stem 14 can be made large, the separation interval between the one end opening edge 21 and the gasket 20 can be increased, and the unit This makes it possible to increase the amount of high viscosity content spouted per hour, thereby improving work efficiency.

In the present invention, as described above, the sealing member and the posture maintaining member are formed separately, and the gasket, which is the sealing member, is formed into a flat plate shape that does not protrude to the outer surface of the mountain cup. is not inhibited,
It becomes possible to obtain a large inclination angle of the stem with a weak force, and it becomes possible to eject a large amount of high viscosity contents per unit time for a long time, thereby improving work efficiency.

[Scope of utility model registration request] One end of the stem is inserted into the aerosol container through the mountain cap, and the other end is projected outside, and the spring inserted between the protruding side of the stem and the mountain cap biases the stem toward the other end. The biasing force presses the opening edge of one end of the housing connected to one end of the stem into close contact with a flat gasket that is located on the inner surface of the mountain cap and does not protrude to the outer surface of the mountain cap. The communication between the outlet passage of the stem and the inside of the aerosol container is
An aerosol valve that is always shut off.
