Description

[Detailed Description of the Invention] The present invention relates to an inverted aerosol device that injects the contents while the aerosol container is inverted, and eliminates the need to press the stem of the aerosol container each time the contents are injected. The object is to be able to automatically spray the aerosol contents by inverting the aerosol container. Conventionally, when opening the valve mechanism and spouting out the contents by tilting the stem constituting the aerosol valve, this was done by pressing the stem of the tilt-operated valve from the side in the tilt direction with a thumb or the like. However, this method often places a strong strain on the thumb and the like, making it difficult to eject the aerosol contents.

The present invention eliminates the above-mentioned drawbacks, and includes an injection nozzle connected to a stem configured to eject the contents by pressing in a direction crossing the axial direction. One end of the pressing piece, which has a tapered surface with an expanded axial outer end and forms a pressing portion facing this tapered surface, is rotatably fixed to the main body fixed to the aerosol container and pressed. A heavy object for pressing the pressing piece is slidably positioned between the other end of the piece and the aerosol container, and by changing the aerosol container from an upright state to an inverted state, the other end of the pressing piece and A heavy object for pressing the pressure piece, which is slidably positioned between the aerosol containers, slides down and collides with the other end of the pressure piece, so the pressing part of the pressure piece is pressed against the tapered surface of the nozzle, causing the stem to The contents are ejected by pressing in a direction that intersects with the axial direction. In this case, if the weight of the heavy object is large, continuous injection will be possible, but if the weight is relatively light, the stem will be pushed sideways only at the moment the heavy object collides with the pressing piece, and the aerosol contents will be released for a short period of time. This short-term injection can be repeated by vertically vibrating the aerosol container. In this way, the present invention eliminates the need to press the stem of the aerosol container each time the contents are injected, and the aerosol contents can be automatically injected by inverting the aerosol container. Therefore, it is particularly suitable for aerosol contents such as cosmetics for hair.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an aerosol container, and a stem 3 protrudes from the center of a mounting cup 2 fixed to the upper end thereof, which connects to an internal valve mechanism. This stem 3 is connected to a valve mechanism configured to eject the aerosol contents by pressing in a lateral direction that intersects with the axial direction, and an injection nozzle 4 is connected to the end in the projecting direction. The outer periphery of the nozzle 4 is formed with a tapered surface 5 whose outer end in the axial direction is widened. Further, a main body 6 covering the upper end of the aerosol container 1 is fixed, and an opening 10 in which the injection hole 8 of the injection nozzle 4 is located is formed in the top plate 7 of the main body 6. It is rotatably fixed on a shaft 12. This pressing piece 11
The injection nozzle 4 is inserted through the insertion hole 13 provided in the injection nozzle 4, and the tapered surface 5 of the injection nozzle 4 is exposed to the injection nozzle 4.
One side of the insertion opening 13 is used as a pressing portion 14. In addition, in the distance between the other end of the pressing piece 11 and the aerosol container 1,
A heavy object 15 for pressing the pressing piece 11 is slidably positioned in an insertion interval 17 formed by cutting out a part of the inner wall 16, and is also provided at a distance between the other end of the pressing piece 11 and the top plate 7 of the main body 6. 18 is interposed. These springs 18 contract when the heavy object 15 collides with the tapered surface 5, allowing the pressing part 14 to press the tapered surface 5, and after being temporarily pressed, restore to such an extent that the pressure on the tapered surface 5 can be released. It is my strength. This spring 18 is not necessarily required, and may not be formed in other different embodiments.

Since the present invention is constructed as described above,
By changing the aerosol container 1 from an upright state to an inverted state, a heavy object 15 for pressing the pressing piece 11, which is slidably positioned between the other end of the pressing piece 11 and the aerosol container 1, slides. Since it collides with the other end of the pressing piece 11, the pressing part 14 of the pressing piece 11 is pressed against the tapered surface 5 of the injection nozzle 4, and by pressing the stem 3 in the direction crossing the axial direction, the aerosol contents are released. gush. In this case, the weight of the heavy object 15 is made large and the restoring force of the spring 18 is made small, or continuous injection is possible if the spring 18 is not provided, and the weight of the heavy object 15 is made relatively light. If you put the heavy object 15 on the pressing piece 1
Only at the moment of collision with the aerosol container 1, the stem 3 is pushed sideways and can spray the aerosol contents for a short time, and this short time spray can be repeated by vertically vibrating the aerosol container 1. be able to.

In this way, the present invention eliminates the need to press the stem of the aerosol container each time the contents are injected,
Since the aerosol contents can be automatically sprayed by turning the aerosol container upside down, it is particularly convenient for use in hair cosmetics and the like, which are often used upside down.
