DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol container which, when used in an application such as an antiperspirant or a hair restorer, provides a massage effect to the skin and prevents inadvertent liquid dripping, and more particularly to a jetted container. The present invention relates to an aerosol container having a configuration in which an aerosol is applied to a target surface by adhering the aerosol to the surface of a ball so as to easily roll the ball.

[0002]

2. Description of the Related Art An aerosol container of this kind is disclosed, for example, in Japanese Utility Model Publication No. 7-18626. As shown in FIG. 5, the aerosol container includes a container body 10 filled with a liquid content in a pressurized state, a hollow stem 20 attached to the container body 10 so as to eject the content liquid as an aerosol, A ball 30 for attaching the aerosol jetted from the stem 20 to the surface thereof, and a holder 40 attached to the container body 10 so as to rotatably hold a part of the ball 30 in a state of being exposed to the outside.
And a valve body 50 that engages with the stem 20 and elastically supports the ball 30 in cooperation with the holder 40.

[0003] The holder 40 receives the ball 30 on its upper receiving surface 41, and forms a pouring passage 42 between the ball receiving surface 41 and the ball 30. Further, a valve seat 51 is attached to the lower portion of the holder 40 integrally with the hollow stem 20, and an ejection passage 52 communicating with the hollow stem 20 is formed inside the valve seat 51. Further, the valve body 50 is elastically supported via a piston spring 53 provided in the ejection path 52,
The valve body 50 normally presses the inner wall 43 of the holder 40,
The ejection passage 52 formed in the valve seat 51 and the ejection passage 42 formed between the ball 30 and the holder 40 are shut off.

Accordingly, the aerosol container operates as follows.

In use, when the exposed portion of the ball 30 comes into contact with the target surface, the ball 30 is pressed inward of the holder 40, so that the valve body 50 is opposed to the piston spring 53 and the holder inner wall 43. From the ejection path 52 and the ejection path 42. At this time, the hollow stem 20 ejects the aerosol into the ejection passage 42 via the ejection passage 52, attaches the aerosol to the surface of the ball 30, and rolls the ball 30 to apply it to the target surface.

According to the aerosol container, the required massage effect on the skin can be obtained by the ball 30.

[0007] However, the above-mentioned prior art has the following problems. First, although the ball 30 is supported by the piston spring 53 via the valve body 50,
Since the vertical movement of the ball 30 is regulated by the receiving surface 41 of the rigid holder 40, the movement of the ball 30 is restricted, and there is a surface on which the massage effect cannot be sufficiently exerted.

Further, since the piston spring 53 is generally made of a metal material, there is an inconvenience that the chemical resistance to the contents filled in the container body must be taken into consideration in terms of durability and the like. There is. On the other hand, in consideration of environmental issues which have recently become important, it is desirable that each component constituting the container should be easy to dispose and do not impose an unfavorable load on the environment. If it is manufactured, it is necessary to separately collect the ball 30, the holder 40, the valve body 50 and the like, which are usually plastic molded products. Needless to say, such sorting work is generally complicated and may not always be performed.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is easy to dispose after use while improving durability and more comfortable. An object of the present invention is to provide an aerosol container that can provide a massage effect and that prevents inadvertent liquid dripping with a simple configuration.

A container, said seat, with the exception of aerosol injection holes area in the stem and is characterized in that it comprises an elastic partition wall for isolating the stem from the ball.

In this case, when the exposed portion of the ball comes into contact with the target surface, the ball is pressed toward the inside of the holder, so that the hollow stem releases the aerosol from the aerosol ejection hole of the elastic partition. The aerosol is sprayed, and the aerosol is attached to the surface of the ball, and the ball is rolled and applied to the target surface.

That is, in the aerosol container of the present invention, the elastic partition receives the ball on the upper receiving surface, and the lower part of the elastic partition engages with the hollow stem to hold the ball with the holder. Elastic support under the cooperation of the above, the vertical movement of the ball is largely secured, a more comfortable massage effect is obtained, and the variation existing between the stem and the ball is absorbed, and the careless liquid The effect of preventing dripping can be obtained. Further, since it is not necessary to use a metal piston spring or the like, the chemical resistance to the contents filled in the container body is improved, and the durability of the aerosol container is improved. In addition, since there is no need to separate the components that make up the container, disposal after using the aerosol container is easy.

Therefore, according to the first aspect of the present invention, while improving the durability, the disposal treatment after use is easy, a more comfortable massage effect can be obtained, and a careless dripping is prevented with a simple structure. It is possible to do.

In another embodiment, it is preferable that the elastic partition has a thin, brittle portion in a region adjacent to the aerosol ejection hole region. In this case, a large elastic force can be efficiently obtained.

Further, in these embodiments, it is preferable that the elastic partition has a passage for replenishing aerosol on a surface facing the ball. in this case,
The aerosol ejected from the hollow stem can be evenly supplied to the surface of the ball.

Further, in these embodiments, it is preferable that the holder is formed in a shape capable of substantially linearly contacting the ball. In this case, liquid dripping from between the ball and the holder can be reliably prevented.

In addition, in these embodiments, it is preferable that the holder is formed integrally with the seat. In this case, the number of parts can be reduced and cost can be reduced.

In another embodiment, it is preferable that the holder is formed separately from the seat.
In this case, the material of the seat can be selected in a wider range irrespective of the material of the holder in order to develop the elastic supporting force required for the seat.
