Description

[Detailed description of the invention] Industrial application field This invention relates to an aerosol valve for high viscosity materials, and is an aerosol valve filled with high viscosity materials such as toothpaste, shaving cream, adhesives, caulking agents, and grease. It is used for containers.

Conventional technology Conventionally, aerosol valves for high viscosity materials used in aerosol containers filled with high viscosity materials such as toothpaste, shaving cream, adhesives, caulking agents, and grease have been designed to prevent valve clogging due to high viscosity materials. Therefore, a tilt valve is used in which the contents are discharged by enlarging the outlet for the contents and tilting the stem to the side that intersects with the axial direction. However, with this tilt valve, the amount of content ejected varies significantly depending on the angle of inclination to the side.
It had drawbacks such as insufficient airtightness and frequent leakage accidents.

Problems to be solved by the invention This invention aims to solve the above-mentioned problems, and is designed to prevent the amount of content ejected per hour from varying depending on the amount of pressure on the stem, and to achieve a high degree of airtightness. The purpose is to enable retention and reliably prevent leakage accidents.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has been developed by inserting one end of the stem, which has a content outlet path in the direction of the central axis, into the housing of an aerosol container, and allowing the content to be guided out through a gasket. The stem is urged outward while communicating with the inside of the housing, and the protruding portion of the urged stem is slidably inserted into an outer cylinder fixed to an aerosol container, and one end of this outer cylinder is inserted into the outer cylinder fixed to the aerosol container. an outlet opening that can communicate with the outlet passage;
The stem is abutted and closed by a closing portion at the outer end of the stem, and a pressing protrusion for pressing and sliding the stem protrudes outward from an elongated hole provided in the axial direction of the side surface of the outer cylinder.

Operation In the device configured as described above, in order to inject high viscosity contents, the stem is pressed by pressing the pressing protrusion for stem pressing and sliding that protrudes from the elongated hole on the side of the stem. Can be slid. By this pressing, two closures in the flow path for high viscosity contents, the outlet closed by the closure and the outlet closed by the gasket, can be opened in one action, improving operability. You can make it better. After the injection is completed, if the pressure on the stem is released, it returns to its original position due to the restoring force of the spring or the like, and the outlet and the outlet can be closed at the same time.

Also, the stem is not tilted laterally,
The content is injected by completely opening the outlet and the outlet path through axial pressure movement, so the amount of content ejected per hour can be quantified, and it can be tilted like a tilt valve. There is no change in ejection amount depending on the angle. In addition, since the outlet port, which is the tip of the ejection path, can be sealed with a closing part, the high viscosity content remaining in the outlet path will not harden and cause valve clogging. be.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. 1 is an aerosol container, a mountain cup 3 is fixed to the upper end of the body 2, and a stem 4 protrudes from the center of the mountain cup 3. . This stem 4 has a housing fixed to the mountain cup 3 of the aerosol container 1, and has a passage 5 for discharging high-viscosity aerosol contents such as toothpaste, shaving cream, adhesive, caulking agent, and grease in the central axis direction. One end is slidably inserted into the housing 6, and an introduction hole 7 provided in the side surface of this inserted part so as to communicate with the outlet passage 5 is closed by a gasket 8 fixed to the upper end of the housing 6 when not in operation. As a result, the outlet passage 5 and the inside of the housing 6 are communicated through the gasket 8. Also this stem 4
The stem 4 is urged outwardly by a spring 10 installed in the housing 6 so that its end protrudes outside the housing 6, and the protruding part of the stem 4 is slidably inserted into the outer cylinder 11. .

This outer cylinder 11 is fixed to the aerosol container 1 by fixing the fixing collar 12 on the outer periphery of the base end between the inner surface of the mountain cup 3 and the gasket 8, and has an outlet port 13 for high-viscosity contents at one end. By abutting and closing the conical closing portion 14 at the outer end of the stem 4 against the outlet port 13 when the stem 4 is in the non-operating state, the outlet port 13 is opened and the outlet port 13 is closed. This prevents communication between the outlet path 5 and the outlet port 13. Further, in the axial direction of both sides of the outer cylinder 11, there are elongated holes 16 extending from the fixed collar 12 to approximately the middle part.
is opened, and a pressing protrusion 17 protruding from the side surface of the stem 4 is protruded outward from this elongated hole 16, and the outer cylinder 11
A handle 20, one end of which is rotatably fixed to the outer surface of the press with a fixed shaft 18, is placed on the upper surface of the pressing protrusion 17,
By pressing the handle 20 using the fixed shaft 18 as a fulcrum, the stem 4 can be pressed and slid against the restoring force of the spring 10.

In addition, in order to prevent this pressing and sliding action during storage, transportation, etc., a ring 21 for preventing malfunction is rotatably positioned on the outer periphery of the outer cylinder 11, and the pressing protrusion 17 is brought into contact with the stem 4. An abutment plane 22 that makes movement of the stem 4 difficult, and an operating plane 23 that does not cause any hindrance to the movement of the stem 4 are formed on the upper edge.

In the configuration as described above, in order to inject the high viscosity content, the handle 20 is pressed and the pressing protrusion 17 protruding from the elongated hole 16 is pressed, thereby causing the pressing protrusion 17 to protrude. The stem 4 is pushed and slid in the valve opening direction against the restoring force of the spring 10.
By this pressing, it is possible to open the two closing parts of the outlet port 13, which is closed by the closing part 14, and the outlet passage 5, which is closed by the gasket 8, in the flow path of the high-viscosity contents. This improves operability and enables easy ejection of high viscosity contents. Further, when the pressure on the handle 20 is released, the stem 4 is restored to its original position by the restoring force of the spring 10, and the outlet port 13 and the outlet path 5 can be closed by an action opposite to that described above. In addition, since it is possible to seal the outlet port 13 at the tip of the ejection path with the closing part 14, the high viscosity content remaining in the outlet path 5 is brought into contact with air and hardened. It does not cause clogging.

Effects of the invention Since the present invention is constructed as described above, the outlet opening is opened and closed by the closing part and the gasket is opened and closed in the flow path for high viscosity contents by the pressure and sliding of the stem. The two opening/closing portions of the outlet path can be opened and closed by a single action of pressing or releasing the pressure on the stem, enabling a simple injection operation.

In addition, the stem completely opens the outlet and the outlet path by pressing in the axial direction and injects the contents, so it is possible to quantify the amount of the contents ejected per time, and the tilt Unlike valves, there is no change in ejection amount depending on the inclination angle. In addition, since the outlet at the tip of the ejection path can be reliably sealed by the closing part, the highly viscous contents remaining in the outlet are brought into contact with air and hardened, preventing valve clogging. It is something that never occurs.
