Description

[Detailed description of the invention] The present invention relates to an aerosol valve that can arbitrarily change and adjust the amount of content sprayed per hour. It is a mountain cup fixed to the upper end of an aerosol container, and the upper end of a housing 3 is fixed to the inner surface via a gasket 2.

4 is a gas phase introduction hole drilled in the lower wall 5 of the no-using 3;
A communication port of the dip tube 7 formed on the lower surface of the bottom wall 5 of the Hano Uji Puffer 30, 8 is a center port 9 that communicates with the communication port 6.
The lower wall 5 of the housing 30 is a cylindrical body having a central part axially protruding in a cylindrical shape and having a communication opening 10 extending vertically in the axial direction and communicating with the center opening 9.

Although only one communication opening 10 may be provided, it is preferable to form two communication openings 10 on both sides of the center opening 90 in relation to the stem described later.

Reference numeral 11 denotes a protruding wall protruding from the inner wall surface of the housing 3, and the upper end thereof is a sliding surface 12 protruding in an arc shape.

Reference numeral 13 denotes a stem whose lower end is inserted into the housing 3 and whose upper end projects from the mountain cup 1 to the outside of the aerosol container, and the lower end is formed with a covering cylinder 14 into which the cylindrical body 8 is rotatably and slidably inserted. ing.

Reference numeral 15 denotes an adjustment opening drilled in the outer circumferential direction of the covering tube 14. By forming the opening lower side 16 in a tapered shape, the opening diameter in the axial direction is varied from one end 17 to the other end 18, and the opening area is uniform. The portion communicates with a portion of the communication opening 10 to form an outlet 19 for the contents.

By rotating the stem 13, the outflow port 19 becomes small if the small diameter part in the direction 17 of the adjustment opening 15 communicates with the communication opening 10, and the large diameter part in the direction 18 of the other end communicates with the communication opening 10. If it communicates with the outlet 19, the outlet 19 becomes a dog.

A pressure spring 20 is interposed between the upper end of the cylindrical body 8 and the stem 13, and urges the stem 13 toward the outside of the aerosol container.

Reference numeral 21 denotes a protruding portion of the stem 13 in the biasing direction, which forms a content outlet path 22 in the central portion and also forms a content outlet path 22 in the center portion.
The outlet hole 23 communicating with the gasket 2 is normally sealed with a gasket 2.

24 is a protruding part protruding from a part of the outer peripheral surface of the stem 13;
The stem 13 is formed on the lower end 1V-shaped side 25 and installed inside the housing 3.
When the stem 13 is inserted into the housing 3 by sliding the sliding surface 12 to the left or right, the stem 13 is inserted into the housing 3 at a proper position. It rotates within the range where it can communicate, and when it is outside the range, it abuts against the protruding wall 11 of the housing 3,
This makes it difficult to rotate the stem 13.

Reference numeral 26 denotes a flow interval between the contents and the gas phase formed between the outer periphery of the stem 13 and the inner surface of the housing 3, and communicates with the outlet hole 23 only when the stem 13 is pressed.

In the structure as described above, the stem 13 is pressed by the spring 2.
When pressed against the restoring force of 0, the gasket 2 deforms and opens the outlet hole 23, so the contents are transferred to the dip tube 7, the communication port 6, the center port 9, the communication port 10, and the adjustment port 15.
It flows out into the flow interval 26 in the maggot pufferfish 3, but by rotating the stem 13, the outflow port 19 formed by the communication opening 10 and the adjustment opening 150 overlap can be opened arbitrarily as described above. Since the area can be changed, the amount of content ejected can also be adjusted by increasing or decreasing in proportion to the opening area of the outlet 19.

Further, in the above embodiment, the communication opening 10 is vertically elongated, and the adjustment opening 15 is tapered at the lower side 16, and has a different diameter from one end 17 to the other end 18, but in other different embodiments. The shape of this opening may be completely reversed, and in other different embodiments, both of the openings may be horizontally elongated, and if the amount of contact polymerization is small, the outlet 19 will be small, and if the amount of polymerization is large, the outlet 19 will be large. In short, any material that can adjust the area of the outflow port 190 by overlapping the two openings will suffice.

However, it is meaningless to make the opening area of the outflow port 19 larger than the opening area of the communication port 6 communicating with the stem 13 because the maximum amount of outflow is determined by the opening area of the communication port 6.

As mentioned above, this invention can change the amount of content sprayed out by arbitrarily adjusting the opening area of the outlet, so if it is used in a coating type aerosol device for paints, etc., a large amount can be sprayed over a large area, resulting in efficient spraying. It is possible to spray a small amount on small areas or areas with many changes to achieve a flawless finish, and when used for glass polishing, it can be used in areas with strong stains or in small amounts. It enables various usage methods depending on needs, such as spraying a small amount.
