Description

[Detailed description of the invention] The present invention relates to an aerosol valve for high viscosity substances. Conventional aerosol valves for high viscosity substances have a spout, etc. that uses a thick tubular nozzle to facilitate the ejection of high viscosity contents. It was formed by
After the jetting operation, the contents remaining in the tubular nozzle portion come into contact with the outside air and harden, often making subsequent jetting of the contents impossible.

The present invention eliminates the above-mentioned drawbacks by inserting a sliding body into the inner circumferential surface of the housing so as to be slidable while maintaining airtightness, and using this sliding body to open the spout opening in the side wall of the housing. When the sliding body is closed and the sliding body is pressed down, the ejection port opened in the side wall of the housing can be connected to the outlet of the sliding body that communicates with the inside of the aerosol container, and the contents can be connected to the side wall of the housing. Since the jet nozzle is formed, even if the highly viscous contents adhering to the jet nozzle harden, they can be easily removed, and they do not use stems, push buttons, spouts, etc. Therefore, it is possible to open the side wall of the housing with an opening area sufficient to eject the highly viscous material. In addition, this large opening area is opened and closed by a sliding body that is slidably inserted into the inner circumferential surface of the housing while maintaining airtightness, so unlike the conventional method where the content passage is opened and closed at the end face of the gasket. as,
The present invention is not limited to opening and closing only a small area, but can reliably open and close an ejection port that is a wide area opening.

An embodiment of the present invention will be described below with reference to the drawings. 1 is an aerosol container filled with a high viscosity substance;
A fixing collar 5 of a housing 4 is fixed to the clinch portion 2 at the upper end via a packing 3. The housing 4 has a communication port 7 in the lower bottom wall 6 which is in constant communication with the aerosol container 1, and a spout port in the side wall 8 with a sufficient opening area to spray the contents, which are highly viscous substances such as adhesives and caulking agents. 9 is open. In addition, a sliding body 11 is slidably inserted into the housing 4 while maintaining airtightness by bringing the outer peripheral surface into close contact with the inner peripheral surface of the housing 4.
Due to the urging force of the spring 12, the top plate 1 of the housing 4 is
3, the outer peripheral surface of the sliding body 11 seals the spout 9. Also, the sliding body 11
An outlet port 14 communicating with the inside of the aerosol container 1 is formed at one end in the pressing direction, and the outlet port 14 is pressed by the biasing force of the spring 12 against one surface of a gasket 15 interposed in a space between it and the top plate 13. Therefore, the top plate 1 is normally closed and one end of the sliding body 11 is closed.
A pressing protrusion 16 is formed that protrudes to the outside of the housing 4 via the engaging part 1 of the pressing protrusion 16.
7 is engaged with the gasket 15.

In the configuration as described above, if the sliding body 11 is made to slide by pressing the pressing protrusion 16 against the biasing force of the spring 12, the spout 9 will move against the sliding body 11.
By being released from the seal by the outer peripheral surface of
As shown in FIG. 2, the high viscosity contents 18 are
The gasket 15 is pressed open and the gas is ejected from the ejection port 9 to the outside. When the pressure on the pressing protrusion 16 is released, the sliding body 11 returns to its original position due to the restoring force of the spring 12, and the ejection of the high-viscosity contents 18 is stopped, and the high-viscosity contents remaining in contact with the outside air are removed. Since it is only the part of the spout 9 that opens in the side wall 8 of the housing 4, it is easy to remove even if it hardens.
This will not make the next eruption difficult.

Further, in the above embodiment, the sliding body 11 has its outer circumferential surface in close contact with the inner circumferential surface of the housing 4, and the outlet port 1
4 was pressed against the gasket 15 to maintain airtightness, but in other different embodiments, as shown in FIG. The airtightness may be maintained by interposing O-rings 20 and 21 between the top plate 13 and the top plate 13, and by bringing the outlet 14 into close contact with the inner surface of the top plate 13. In yet another embodiment, as shown in FIG. 4, a contact piece 22 having elasticity may be formed on the outer periphery of the sliding body 11 to maintain airtightness. Further, in each of the above embodiments, the sliding body 11 presses the pressing protrusion 16 having a T-shaped cross section from the top surface, but as shown in FIG. By fixing one end of the pressing protrusion 16 to and connecting the pressing lever 24 to the other end of the pressing protrusion 16, the sliding body 1
It also becomes possible to make the pressing of step 1 easier.

As described above, the present invention has a spout for the contents formed in the side wall of the housing, so even if the contents adhered to the spout harden, it can be easily removed, and it can be removed easily compared to the conventional method. Since the device does not use a stem, push button, spout, etc., it is possible to open the side wall of the housing with a sufficient opening area for spouting a highly viscous substance. In addition, this large opening area is opened and closed by a sliding body that is slidably inserted into the inner circumferential surface of the housing while maintaining airtightness, so unlike the conventional method where the content passage is opened and closed at the end face of the gasket. The present invention is not limited to opening and closing only a small area, but can reliably open and close an ejection port having a wide area.
