[Industrial application field]

This invention sprays aerosol contents such as a hair growth agent directly onto the scalp, giving it a massage effect. This relates to a push button for an aerosol container whose purpose is to obtain

0002

[Conventional technology]

Conventionally, aerosol contents such as hair growth agents have been used to promote hair growth. After applying the hair aerosol contents, massage the scalp with your hands, brush, etc. is being carried out. However, these methods are laborious and time-consuming. It has some drawbacks. The contents are also sprayed at high pressure to directly stimulate the scalp. However, if the aerosol contents are continuously sprayed at high pressure, the A large amount of the contents will be squirted out, which is not only uneconomical but also causes the contents to scatter and cause a large amount of This may cause problems such as excessive amounts of contents spilling out. In addition, the intermittent injection can be controlled by pressing the push button. It is difficult to adjust it manually.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention aims to communicate with the stem of the aerosol container. A mounting frame is inserted and fixed into the push button body from the side, and the push button is slidably mounted within this mounting frame. The nozzle body is pressed inward of the push button body by the mounting spring, and the nozzle A needle valve is slidably attached to the body, and the needle valve is attached with a weaker recovery force than the attachment spring. The opening/closing line of the original force presses the push button body outward, and the contents are not sprayed. The tip of the needle valve presses and seals the nozzle hole of the nozzle body, and the needle valve The other end is passed through the inlet to allow the contents to flow into the nozzle body. An on-off valve is formed at the other end of the needle valve on the penetrating side, and this on-off valve is In the non-injection state, it is located with an open interval from the inlet, and this open interval is It is formed to a size that allows the introduction port to be sealed when the nozzle hole is opened.

[0005]

[Effect]

Since the present invention is constructed as described above, the aerosol contents are intermittently dispensed. To spray, press the push button body to open the control valve of the aerosol container. This system When the control valve opens, the aerosol content ejected from the stem is controlled by the opening interval and the inlet. Introduced into the nozzle body through the nozzle. This nozzle body presses the nozzle hole with a needle valve. Since it is sealed, the internal pressure increases with the introduction of the aerosol contents. child If the increase in internal pressure exceeds the restoring force of the installed spring, the nozzle will resist the restoring force of the installed spring. The push button body slides toward the outside of the push button body.

[0006] At the same time, the needle valve is also pushed outward by the restoring force of the opening and closing strip, but the needle The valve is slidably mounted inside the nozzle body, so the on-off valve slides through the opening interval. When it hits the inlet, it stops moving. Then only the nozzle body slides further and the needle valve Release the pressure seal of the nozzle hole. By releasing the pressure seal of this nozzle hole, Sprays the aerosol contents inside the nozzle body to the outside.

[0007] The needle valve installed inside the nozzle body is pressed by the opening and closing mechanism as described above. Since the push button body is pressed outward, the push button body slides outward and opens and closes. Close the inlet with a valve. By closing this inlet, aerosol enters the nozzle body. By stopping the introduction of the contents of the nozzle body, the pressure inside the nozzle body with the nozzle hole open will drop. Ru. This decrease in internal pressure causes the nozzle body to move inside the push button body due to the restoring force of the mounting spring. Sliding in the direction of the part.

[0008] By sliding the push button body back inward, the needle valve opens and closes. The restoring force presses and seals the nozzle hole again, preventing the aerosol contents from spewing out. . Also, the opening/closing spring that presses the needle valve has a weaker restoring force than the installed spring, so As the slide body slides, it slides inward of the push button body. This needle valve The restoring slide opens the on-off valve and allows the introduction of the aerosol contents. child By opening the inlet of the nozzle, the introduction of the aerosol contents into the nozzle body begins, and the gas When the pressure becomes higher than the installed spring, the aerosol contents are pumped out from the nozzle hole again. gush.

[0009] As mentioned above, the aerosol contents are ejected or stopped ejecting in an alternating and continuous manner. By doing this, the aerosol contents are intermittently sprayed while the push button body is pressed. Can get a good massage effect with a small amount of aerosol content be able to.

0010 In addition, when the aerosol contents are ejected, the inlet is closed with an on-off valve and the aerosol is This makes it impossible to introduce the contents into the nozzle body. Only the azole contents can be jetted out at once, making it possible to spray a fixed amount.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. (1) is the push button body, and the aerosol The stem (2) of the bottle container is connected and fixed, and the aerosol content communicating with this stem (2) is connected and fixed. A material ejection path (3) is formed in the axial direction. Also, this push button body (1) is A mounting frame (4) is inserted and fixed from the surface so as to be able to communicate with the jetting passage (3). This installation The frame (4) has a bulkhead (6) inserted into the insertion opening (5) that communicates with the ejection path (3) of the push button body (1). The partition wall (6) is provided with an inlet (7) that communicates with the jetting passage (3). .

0012 In addition, the nozzle body (8) is slidably mounted in the axial direction within this mounting frame (4), and the nozzle The tip portion provided with the hole (9) can protrude from the sliding opening (12) of the mounting frame (4). The nozzle body (8) has a flange (11) protruding from the outer periphery on the partition wall (6) side. Mounted between the screw (11) and the inner stepped portion (13) formed on the inner circumferential side of the tip of the mounting frame (4). A spring (14) is inserted to press and bias the nozzle body (8) toward the inside of the push button body (1). Ru.

[0013] In addition, a needle valve (15) is inserted in the nozzle body (8) in the axial direction of the nozzle body (8). It is attached so that it can move. This needle valve (15) has an annular protrusion on the side surface in the axial direction. A mounting spring (16) is formed protrudingly between the annular protrusion (16) and the partition wall (6). 4) The needle valve (15) is inserted into the opening/closing spring (17) with a weaker restoring force than the button body ( 1) is pressed and biased in the outward direction. And when the contents are not injected, this knee The tip of the dollar valve (15) presses and seals the nozzle hole (9) provided at the tip of the nozzle body (8). ing.

[0014] In addition, the other end of the needle valve (15) is inserted into the inlet (7) formed in the partition wall (6). The holes are penetrated at intervals to allow the introduction of. And this penetrating side needle valve (15) An on-off valve (18) is formed at the other end. This on-off valve (18) is a needle valve (15) Attach a gasket etc. to the outer periphery of the inlet port (7) and make it larger in diameter than the inlet port (7). When the sol contents are not injected, an open interval (19) is provided between the inlet and the inlet (7). Ru. When the push button body (1) of the needle valve (15) slides outward, the partition wall (6) The on-off valve (18) is placed against the side of the ejection path (3) to make it possible to close the inlet (7) and Movement of the needle valve (15) toward the nozzle hole (9) can be stopped. open again The dimension of the interval (19) is the dimension on which the nozzle body (8) slides when the aerosol contents are ejected. When the aerosol contents are injected, the needle valve (15) is used to This makes it possible to release the pressure seal of the drain hole (9).

[0015] In the configuration as described above, when the aerosol contents are intermittently sprayed, presses the push button body (1) to open the control valve (not shown) of the aerosol container. child By opening the control valve, the aerosol contents ejected from the stem (2) are (19) and is introduced into the nozzle body (8) via the inlet (7). This nozzle body (8) is Since the nozzle hole (9) is press-tightly sealed with the needle valve (15), the aerosol contents are The internal pressure increases due to the introduction. This increase in internal pressure causes the installation spring (14) to recover. When the original force is exceeded, the nozzle body (8) resists the restoring force of the mounting spring (14) and the push button body ( 1) Slide in the outward direction.

[0016] At the same time as this push button body (1) slides, the needle valve (15) also restores its opening/closing strip (17). Press and move outward with force. However, the on-off valve (18) moves through the opening interval (19), When the needle valve (15) moves until it hits the partition wall (6), the needle valve (15) moves. stop. The sliding distance of the nozzle body (8) is made longer than the opening interval (19). Therefore, even if the needle valve (15) stops moving, the nozzle body (8) will continue to slide. do. By sliding only this nozzle body (8), the nozzle is discharged by the needle valve (15). Release the pressure seal of the nozzle hole (9) and introduce a small amount of aerosol content into the nozzle body (8) Only things are ejected to the outside.

[0017] Further, as mentioned above, the needle valve (15) is connected to the push button body (1) by the opening/closing member (17). Since the inlet port (7) is pressed outwardly, the inlet port (7) is closed by the on-off valve (18). child By closing the inlet (7), the introduction of the aerosol contents into the nozzle body (8) is stopped. Therefore, the pressure inside the nozzle body (8) that ejected the aerosol contents to the outside decreases. . When this internal pressure decreases below the restoring force of the mounting spring (14), the nozzle body ( 8) is restored by sliding toward the inside of the push button body (1) by the restoring force of the mounting spring (14).

[0018] By sliding the push button body (1) inward, the needle valve (15) opens. The restoring force of the opening and closing line (17) presses and seals the nozzle hole (9) again, and the aerosol contents are released. There is no gushing. In addition, the opening/closing spring (17) that presses the needle valve (15) is Since the restoring force is weaker than that of the landing strip (14), as the nozzle body (8) slides, the push button It slides inward of the main body (1). This restoration sliding of the needle valve (15) opens the needle valve (15). The closing valve (18) is opened to allow the aerosol contents to be introduced from the inlet (7). By opening this inlet (7), the introduction of the aerosol contents into the nozzle body (8) is opened. At the beginning, if the gas pressure becomes higher than the installed spring (14), the gas is recirculated to the outside from the nozzle hole (9). and ejects the aerosol contents.

[0019]

[Effect of the idea] Since the present invention is constructed as described above, the adjustment is automatic rather than manual adjustment. The aerosol contents can be sprayed intermittently, and a small amount of spray will irritate the scalp. It is possible to obtain a massage effect by giving This allows for economical use without creating a sink or the like.
