Description

[Detailed Description of the Invention] Industrial Application Field The present invention is particularly suitable as an aerosol valve for an aerosol container filled with a highly viscous content such as an adhesive or a caulking agent.

Conventional Technology Conventionally, one type of aerosol valve for an aerosol container filled with high-viscosity contents such as adhesives and caulking agents is a tilt-action valve that sprays the liquid by tilting its stem. . This valve has the advantage of being able to open a large inlet that guides high-viscosity contents to the injection port, but
A strong force is required to open the valve, and the contents can only be injected while this valve-opening operation continues, so it is difficult to inject a large amount of contents for a long time due to finger fatigue. It was difficult.

In addition, in push-down valves that open by pushing down the stem in the axial direction, the inlet that leads high-viscosity contents to the injection port is closed by a gasket located on the outer periphery of the stem. If the inlet is made large, it becomes difficult to maintain airtightness, and since the diameter of the inlet is limited, the valve is likely to become clogged, and the contents can only be filled while the valve continues to open. They had the same drawbacks as tilt-action valves in that they cannot be injected and it is difficult to inject a large amount of content for a long period of time due to finger fatigue.

Problems that the invention attempts to solve The present invention attempts to solve the problems mentioned above.
While preventing valve clogging, there is no airtight leakage, and with only one valve opening operation, there is no need for continuous pressure on the stem, and it can be used for long periods of time without causing finger fatigue. It is intended to make it possible to inject highly viscous contents.

Means for solving the problems In order to solve the problems mentioned above, the present invention
A stem provided with a communication path that communicates the outside of the aerosol container and the inside of the aerosol container is screwed into the housing fixed to the lid of the aerosol container so that it can move up and down, and the side wall of either the stem or the housing A communication port for the contents to pass through is provided, and a lower bottom wall is formed at the lower end of either the housing or the stem to block communication between the communication path of the stem and the inside of the aerosol container via the communication port. It is characterized by:

Function Since the present invention is constructed as described above, communication between the communication path of the stem and the inside of the aerosol container via the communication port is normally maintained by the lower end of either the housing or the stem. If it is blocked by the bottom wall, the communication path of the stem will not communicate with the inside of the aerosol container, the airtightness of the inside of the aerosol container will be maintained, and the contents will not be sprayed.

In addition, in order to inject the contents inside the aerosol container, the stem is rotated and moved up or down according to the spiral groove, so that the communicating path of the stem communicates with the inside of the aerosol container, and the contents flow through the stem. It is then sprayed to the outside.

The contents inside the aerosol container can be sprayed by simply rotating the stem as described above, and since the spray continues until the stem is reversed to return to its original position, it does not cause finger fatigue. It enables a large amount of injection for a long period of time. Furthermore, a gasket is not used to open and close the communication path, and the communication port for introducing the contents of the aerosol container into the communication path is formed on the side of the housing or stem, so a large opening can be formed freely. This makes it possible to easily discharge even highly viscous contents.

Embodiment The first embodiment of the present invention will be described below with reference to FIGS. In this housing 2, a stem 6 is provided with a communication passage 5 that communicates the outside of the aerosol container with the inside 4 of the aerosol container, and a rotating operation collar 7 is fixedly protruded from the outer periphery so that the stem 6 can be moved up and down. A screw is inserted. In addition, the stem 6 is provided with a communication port 8 for the contents to pass therethrough, which connects the inside 4 of the aerosol container and the communication path 5, by cutting out the side wall. A large lower bottom wall 10 is fixedly formed, and an operating collar 7 is provided.
When the stem 6 is rotated and raised, the lower bottom wall 10 abuts against the lower end opening 11 of the housing 2 and is sealed, as shown in FIG.
The communication between the aerosol container and the inside 4 of the aerosol container is cut off, so that the contents do not spray out to the outside. To spray out the contents, invert the aerosol container so that the outlet 12 of the stem 6 is at the bottom, rotate the operating collar 7, and lower the stem 6 as shown in Figure 2. For example, by opening the lower end opening 11 of the housing 2 and communicating the communication path 5 with the inside 4 of the aerosol container through the communication port 8 and the lower end opening 11, the contents can be spouted. , the contents continue to be ejected. Further, to stop the ejection of the contents, the stem 6 is rotated upward in the opposite direction to the above, and the lower bottom wall 10 is brought into contact with the lower end opening 11 of the housing 2 to seal it.

In another different embodiment, the communication between the inside 4 of the aerosol container and the communication path 5 is achieved without forming a communication port 8 in the stem 6 for passing the contents, as shown in FIGS. 3 and 4. , is formed by cutting out the side wall of the housing 2, and a lower bottom wall 10 is formed at the bottom of the housing 2. Then, when the aerosol container is turned upside down and the stem 6 is rotated through the operating collar 7 and the stem 6 is raised, as shown in FIG. 5 and the inside 4 of the aerosol container, the contents can be ejected. Moreover, in order to stop the spouting of the contents, if the stem 6 is rotated via the operating collar 7 and the stem 6 is lowered, the third
As shown in the figure, the lower end opening 11 of the communication passage 5 can be press-sealed to the inner surface of the lower bottom wall 10, and the communication passage 5
Since the communication between the aerosol container and the inside 4 of the aerosol container is cut off, the ejection of the contents can be stopped.

In this specification, terms indicating directions such as upward movement and downward movement are used based on the state shown in the drawings.

Effects of the invention Since the present invention is constructed as described above, the contents inside the aerosol container can be sprayed by simply rotating the stem, and the spraying continues until the stem is reversed to its original position. It does not cause finger fatigue, etc., and enables a large amount of spraying for a long time. Also, since a gasket is not used to open and close the communication port, the communication port is formed on the side of the housing or stem, so it is possible to form a large opening freely, and when the contents are high viscosity. This is particularly convenient and does not cause problems in maintaining airtightness.
