Abstract

PROBLEM TO BE SOLVED: To operate an aerosol jetting utensil from any azimuth, and at the same time, reduce the cost by reducing the number of parts. SOLUTION: A jetting button 20 is attached to the stem 14 of an aerosol container 10. For the jetting button, an operating section 26 is provided around the jetting button itself, and the jetting button is equipped with a nozzle 28 at the tip end. Also, the jetting button is attached in a manner to go through the central hole 32 of a shoulder cover 30. For the shoulder cover 30, a mounting cup-fitting section 34 is attached to a mounting cup 12 of the aerosol container, and an engaging protuberance 36 is engaged with the mounting cup 12. Then, the outer periphery of the base end of the jetting button 20 is covered with the shoulder cover 30. In the meantime, the central hole 32 is closed with a flange section 24 of the jetting button. Thus, when a finger is placed on the operating section 26 and presses the operating section 26, the stem 14 is operated, and a content of the aerosol container is discharged from the stem, and is jetted from the nozzle 28 of the jetting button.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic that is used in an upright or inverted state and injects the contents of an aerosol container from a nozzle at the tip of an injection button in a liquid, mist, foam, powder, or the like. Applicable to aerosol ejectors for air, aroma, insecticide, etc. For example, the present invention relates to an aerosol ejector suitable for use as a point mist when only a part of hair is hardened.

[0002]

2. Description of the Related Art Conventionally, this type of aerosol ejector includes an operating member (pressing member) around an ejection button having an upward nozzle at the tip as described in, for example, Japanese Patent Application Laid-Open No. 9-12434. ) Is provided, and the contents in the aerosol container can be ejected from the nozzle by depressing the ejection button via the operation member.

In this aerosol ejector, an operating member is
There is an advantage that it can be operated from any direction without any direction.

[0004]

However, since an operating member such as a pressing member and a supporting member for supporting the operating member must be provided separately from the ejection button, there is a problem that the number of parts increases and the cost increases. Was.

Accordingly, a first object of the present invention is to make it possible to operate the aerosol ejector from any direction and to reduce the number of parts to reduce the cost.

A second object of the present invention is to improve the appearance of such an aerosol sprayer by preventing the space between the spray button and the mountain cup of the aerosol container from being exposed.

[0007] A third object of the present invention is to eliminate the possibility that foreign matter enters between the injection button and the mountain cup of the aerosol container in the aerosol ejector.

[0008]

Accordingly, the present invention provides
In order to achieve the first object described above, in an aerosol ejector, a spray button is attached to a stem of an aerosol container, and when the finger is pressed around the spray button itself, the stem is activated to operate the aerosol container. And a nozzle for ejecting the content ejected from the stem is provided at the tip of the ejection button.

According to a second aspect of the present invention, in the aerosol ejector according to the first aspect of the present invention, in order to achieve the second object, the outer periphery of the base end of the injection button is attached to the mountain cup of the aerosol container. It is characterized by being covered with a shoulder cover to be attached.

According to a third aspect of the present invention, in the aerosol ejector according to the second aspect, in order to achieve the third object described above, the shoulder cover is provided with a center hole through which the injection button passes. The injection button is provided with a flange for closing the center hole.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view of a central part of an aerosol ejector according to the present invention when not in use.

Reference numeral 10 in the drawing denotes a can-shaped aerosol container. In the aerosol container, contents for makeup, aroma, insecticide, etc. are stored together with the propellant. As in the conventional case, a mountain cup 12 is provided in an annular shape around the upper edge of the aerosol container 10, and a stem 14 projects upward at the center.

The tip of the stem 14 is fitted into the stem fitting portion 22 of the ejection button 20, and the ejection button 20 is attached to the stem 14.
Attach. The ejection button 20 is located at the center of the ejection passage 21.
And has a slightly tapered shape.
A flange portion 24 is formed on the outer periphery at the base end where is provided. An operating portion 26 is formed by providing a plurality of annular protrusions around the tip. Further, a nozzle 28 is attached in the tip.

By the way, the injection button 20 is connected to the shoulder cover 3.
0 through the center hole 32. The shoulder cover 30 has a mountain cup fitting portion 34 attached to the mountain cup 12, and a locking projection 36 provided on the inner periphery of the lower edge hooked to the lower edge of the mountain cup 12. Then, the outer periphery of the flange portion 24 of the injection button 20 is inserted under the edge of the center hole 32 of the shoulder cover 30 to close the center hole 32 with the collar portion 24, while the shoulder cover 30 covers the outer periphery of the base end of the injection button 20. U.

At the time of non-use, as shown in FIG.
Attach a cap 40 to cover the spray button 20.

Now, when using the illustrated aerosol ejector, the cap 40 is removed, the aerosol container 10 is held, and the nozzle 28 is directed to a target portion. And
As shown in FIG. 2, a finger is applied to the operation unit 26 of the ejection button 20 from the surroundings and the ejection button 20 is pressed, and the stem 14 is operated to discharge the contents in the aerosol container 10 from the stem 14.

The contents discharged from the stem 14 pass through the ejection passage 21 of the ejection button 20 from the tip nozzle 28 toward a target portion, for example, in the form of a liquid, mist, foam, powder, or the like, as indicated by arrows in the drawing. Inject. Thereby, for example, only a part of the hair is hardened as a point mist.

When the operator releases his / her finger from the operation section 26 of the ejection button 20, the stem 14 automatically returns and stops its operation, and the ejection from the nozzle 28 is stopped.

After use, as shown in FIG. 1, the cap 40 is attached to the shoulder cover 30 again, and the ejection button 20 is covered.

[0020]

According to the present invention, the following effects can be obtained. Since the operation unit is provided around the ejection button, the operation unit can be operated from all directions to eject the contents in the aerosol container from the tip nozzle of the ejection button.

Since the operation unit is provided on the ejection button itself, it is not necessary to separately provide an operation member such as a pressing member or a support member for supporting the operation member as in the related art, and it is possible to reduce the number of parts and reduce costs. it can.

[0022] Since the number of parts is small and the operation is simple, it is possible to eliminate the possibility of occurrence of poor injection. The aerosol ejector according to the present invention can be obtained simply by replacing the ejection button of the existing aerosol ejector, so that the conventional aerosol container, shoulder cover, cap and the like can be used as it is.

According to the second aspect of the invention, the outer periphery of the base end of the injection button is covered with the shoulder cover attached to the mountain cup of the aerosol container. You can make it look better.

According to the third aspect of the present invention, since the shoulder cover is provided with the center hole through which the injection button penetrates, and the injection button is provided with the flange portion which closes the center hole, the center hole is formed with the injection button. Foreign matter can be prevented from entering the shoulder cover from between.
