BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the entire structure of an aerosol type injector for a hair nourishing agent as an example of the aerosol type injector according to the present invention.

As shown in the figure, an aerosol type injector 1 comprises a container 2 in the shape of a circular can, an injection head 3 fitted therein, and the like. The container 2 has a slightly narrowed upper opening,
The periphery is rounded outward to form the mouth portion 4, and the stem 5 is provided at the center of the mouth portion 4. Inside the container 2, the hair nourishing agent 6 which is the content to be ejected from the aerosol type ejector 1 is mainly stored in a liquid state, and a liquefied gas such as liquefied dimethyl ether is dissolved as a propellant.

The ejection head 3 is formed by combining a head body 7, a button 8 and a flow path forming member 9 which are made of plastic resin.

As shown in FIG. 2, the head main body 7 has a concavo-convex portion 10 for massage on its top surface, and a cylindrical tubular portion 12 having a central hole 11 at the center of the top surface, and a disc-shaped step portion. 13 and an annular fitting portion 14 are integrally molded. An opening 15 is provided from the side surface of the cylindrical portion 12 of the head body 7 to the step portion 13. Further, as shown in FIG. 3, on the back surface of the stepped portion 13, a pair of concave grooves 1 is formed on the side of the opening 15.
6, 16 are formed.

The button 8 is formed by integrally molding a two-sided substantially right-angled triangular plate part and a one-sided rectangular finger support part 17.
A projection 1 is formed on each of the acute-angled corners of the substantially right-angled triangular plate.
8 and 18, and a rotary shaft 19 is integrally formed at the right angle portion.

The flow channel forming member 9 has a cylindrical flow channel tubular portion 20.
And a cylindrical step portion 21 and a disc-shaped flange portion 22, which are integrally formed. An injection port 23 for injecting a hair nourishing agent is formed at the tip end of the flow path tubular portion 20, and a stem fitting hole 24 is formed in the flange portion 22. The stem fitting hole 24 and the injection port 2
Between 3 is formed a hollow channel.

The jet head 3 is formed by combining the head body 7, the button 8 and the flow path forming member 9 formed as described above as shown by the arrows in FIG.

First, the opening 1 is formed from below the head body 7.
A button 8 is provided through 5, and both ends of the rotary shaft 19 are fitted into the pair of recessed grooves 16, 16 so as to be rotatably attached to the head main body 7 so as to be externally operated. Then, the flow path forming member 9 is inserted into the center hole 11 of the head main body 7, and the tip portion of the flow path forming member 9 is removed from the center hole 11,
Assemble so that the nozzle hole 23 is exposed. At this time, the pair of protrusions 18, 18 of the button 8 is assembled so as to contact the flange portion 22 of the flow path forming member 9.

The jet head 3 assembled in this way
Is fitted with the tip of the stem 5 of the container 2 shown in FIG. 1 in the stem fitting hole 24 of the flow path forming member 9, and the flow path forming member 9 is attached to the stem 5. At the same time, the fitting portion 14 is placed so that the tip of the mouth portion 4 contacts the back side of the step portion 13 of the head body 7.
Is fitted into the mouth portion 4 of the container 2 to form the aerosol type injector 1.

That is, the jet head 3 is attached to the mouth portion 4 of the container 2 of the aerosol type injector 1, and the head main body 7 is attached to the head body 7.
And a button 8 provided through an opening provided in the head body 7, and a flow path forming member 9 provided in the head body 7 and attached to the stem 5. Then, when not in use, the cap 25 is put over the jet head 3.

By the way, when using the aerosol type injector 1 shown in FIG.
Remove. Then, holding the container 2 by hand, as shown in FIG. 4, the ejection head 3 is applied to a desired portion of the head (human body) H with the strength desired by the user, and the unevenness 1 of the ejection head 3 is applied.
At 0, the head H is stimulated and massaged. Next, when the finger-holding portion 17 of the button 8 is pressed with a finger as indicated by the arrow, the button 8 is rotated about the rotation shaft 19 as shown by the solid line from the state indicated by the alternate long and short dash line in the figure, and the projections 18, 18 are formed. Pushes the stem 5 through the flange 22 of the flow path forming member 9. That is, as described above, the stem 5 is the stem fitting hole 2 of the flow path forming member 9.
4 is fitted with the ejection head 3 so that the projection 1
When 8 and 18 push in the collar portion 22, the stem 5 is also pushed in.

Then, the hair nourishing agent 6 is transferred from the container 2 to the stem 5
The hair nourishing agent 6 is ejected through the flow path forming member 9 toward the desired portion of the head H from the ejection port 23.

When the finger is released from the button 8 of the jet head 3, the stem 5 returns, the button 8 returns to the state of the alternate long and short dash line in the figure, and the injection is finished.

When only massage is performed, the container 2
By holding the head with the hand and applying the ejection head 3 to a desired portion of the head H with the strength desired by the user.
The head H is stimulated with and a massage is performed.

Further, when only spraying the hair nourishing agent 6,
When the container 2 is held by hand and the ejection head 3 is applied to a desired portion of the head H, and the finger rest 17 of the button 8 is pressed with a finger, the button 8 rotates about the rotation shaft 19 and the projection 18 , 18 pushes the stem 5 through the flange portion 22 of the flow path forming member 9, and the hair nourishing agent 6 in the container 2 is sprayed to a desired portion.
Then, when the finger is released from the button 8 of the ejection head 3, the stem 5 returns and the ejection ends.

In the present embodiment, the aerosol type injector for spraying the hair nourishing agent to the head at the same time as the massage is performed by applying the unevenness of the injection head to the head, but the present invention is not limited to this. It can be applied to the shoulders, hips, arms, legs, etc. of the human body. For example, the present invention may be applied to an aerosol-type injector in which the projections and depressions of the ejection head are applied to the shoulder and massage is performed, and at the same time, the anti-inflammatory analgesic agent is ejected toward the shoulder.

[0027]

Therefore, according to the present invention, the ejection head has the projections and depressions for massaging and the buttons for ejecting the contents. It is possible to selectively or simultaneously perform the massage of the human body by pressing it against the body and the injection of the contents to the human body.

According to the invention of claim 4, since the jet head according to any one of claims 1 to 3 is provided, the massage of the human body and the jetting of the contents to the human body are selectively or It is possible to provide an aerosol-type injector that can be simultaneously performed.
