Description

[Detailed description of the invention] The present invention relates to an aerosol push button, in which a plurality of injection nozzles are formed on the push button, and all or only one of the plurality of injection nozzles can be arbitrarily selected according to the purpose of spraying, the spray form, etc. The spray pattern can be changed in size by selective use.
Conventionally, push buttons with this type of purpose were manufactured by Jikosho, for example.
No. 48-29202 existed. The push button of this invention has three injection nozzles formed in one push button, and spraying can be done by covering one or two of the nozzles with a rotatable coating around the outer periphery of the push button, or by exposing all of the nozzles. The spray area is controlled by increasing or decreasing the number of possible nozzles, and all of the multiple nozzles are always communicated with the stem. In this state, when the push button is pressed to open the valve inside the aerosol container, the contents are supplied under pressure to all nozzles, so unless the covering body and nozzles are closely connected, the aerosol contents will be covered. It travels through the inside of the body and becomes a state of dripping. The only way to prevent this situation is to form the sheath with a high level of machining precision so that the inner surface of the sheath comes into close contact with the end face of the nozzle. However, it is difficult in practice, and even if it were possible, it would be difficult to form the sheath. Then, mutual rotation of the push buttons becomes impossible due to contact resistance, making it impossible to expose an arbitrary number of nozzles. In short, the above conventional example is extremely difficult to implement in practice.

The present invention eliminates the above-mentioned drawbacks, and includes a push button body that is connected to the stem of an aerosol container and communicates the stem and nozzle through a flow path, and a nozzle portion that is rotatably fixed to the push button body. The nozzle part and the flow path are connected through a control valve, and when one side is rotated, the control valve is opened to communicate the nozzle part and the flow path, and when the other side is rotated, the control valve is closed to communicate with the nozzle part. A rotary nozzle body that blocks communication between channels, and a plurality of nozzles are not formed in one push button, but are formed separately on the push button body and the rotary nozzle body, and the nozzles of the rotary nozzle body are formed separately. By connecting the nozzle part of the rotary nozzle body and the flow passage through the control valve, the nozzle part of the rotary nozzle body and the flow passage of the push button body can be freely communicated by opening and closing the control valve by rotating the rotary nozzle body. Therefore, it is possible to easily control the supply of the contents to the nozzle portion of the rotary nozzle body without using an unreasonable structure such as covering the nozzle portion.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a push button body, which has a communicating part 4 that communicates with the stem 3 of the aerosol container 2 recessed in its lower end surface, and is connected to the communicating part 4 on one side. A flow path 6 communicates with a nozzle 5 formed facing the nozzle. Reference numeral 7 denotes a rotating nozzle body, which is rotatably supported by connecting shafts 10 and 11 between an annular wall 8 projecting annularly from the upper end surface of the push button main body 1, and has a flat upper end surface as a pressing portion 12. . A connecting pipe 13 has one end fixed to the push button body 1 and communicates with the flow path 6. Reference numeral 14 denotes a valve pipe, which is made of a soft elastic material, one end of which is slidably attached to the outer periphery of the connecting pipe 13, the other end of which is fixed to the rotary nozzle body 7, and the tip of a needle inserted and fixed inside. is inserted into the other end of the connecting pipe 13 to form a control valve 15, and the flow path 6 and the nozzle section 16 are connected via this control valve 15.

In the configuration as described above, in order to spray from one nozzle, the pressing part 1 of the rotating nozzle body 7
2. Especially the pressing part 1 at the position where the connecting shafts 10 and 11 are connected
2, the rotary nozzle body 7 presses the push button body 1 without rotating, so the stem 3 is also pressed and the contents are sprayed from the nozzle 5 of the push button body 1. In this state, the contents also flow into the connecting pipe 13, but since the control valve 15 blocks communication with the nozzle section 16, no injection of the contents occurs from the nozzle section 16. Next, the finger hook 17 at one end of the rotating nozzle body 7
Press the rotating nozzle body 7 downward to connect the rotating nozzle body 7 to the connecting shaft 1.
If the valve pipe 1 is rotated in one direction using 0 and 11 as fulcrums, the valve pipe 1
4 rises on the outer periphery of the connecting pipe 13 while appropriately curving, and at the same time the control valve 15 also rises to open the valve seat at the other end of the connecting pipe 13, so that the flow path 6 and the nozzle part 16
The flow passage 6 is connected to both the nozzle part 16 and the nozzle 5 of the push button body 1, and when the rotary nozzle body 7 is further pressed, the push button body 1 is also pressed and the stem 3 is pressed, so that the contents are transferred to the nozzle. 5 and the nozzle part 16, making it possible to obtain a wide spray pattern. The spray pattern can be changed by changing the pressing position of the rotary knob body 7 with respect to the pressing part 12, so that spraying from only the nozzle 5 or from both the nozzle 5 and the nozzle part 16 can be easily selected with one hand operation.

As mentioned above, the present invention allows spraying by selecting one or more nozzles arbitrarily with one hand operation, so a wide spray pattern enables efficient spraying, and a narrow spray pattern allows for delicate spraying work in narrow areas. In addition, due to the presence of the control valve, there is no risk that the contents will leak from the nozzle portion of the rotary nozzle body when not in use.
