Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drug injection container which directly sprays a drug (or a cosmetic agent) such as a hair restorer onto the scalp and exerts a massage effect.

[0002]

2. Description of the Related Art Conventionally, as a spray container that directly sprays a drug onto the scalp and simultaneously exerts a massage effect, for example,
There is one disclosed in Japanese Utility Model Publication No. 2-63360.

This drug injection container supplies a fixed amount of drug, and the part that directly contacts the scalp is composed of a rotatable ball, and is assembled so as not to slip out into the cylinder. In addition, this ball is usually in close contact with the tip of the cylinder by the elasticity of the spring to maintain the injection port of the medicine (the space formed between the ball and the tip of the cylinder) in a sealed state, When it is pressed against, it retreats due to the pressing force, opens its injection port, and supplies a fixed amount of drug to the scalp.

That is, in this medicine injection container,
When supplying a drug to the scalp, the injection port formed between the ball and the tip of the cylinder is opened by the pressing force, and the injection port is closed when the pressing force is released or weakened. is there.

[0005]

However, in the above-mentioned prior art, there is a risk that the hair will be caught in the injection port formed between the ball and the tip of the cylinder during use.

[0006] In this drug injection container, after the drug is supplied to the scalp, the ball is pressed against the scalp and the drug is rubbed against the scalp for massaging. Return to the position of `` '' and close the injection port closely to the tip of the cylinder, and when the injection container is released from the scalp after use, the pressing force is released so the injection port must be sealed. This is because, when the ejection port is in the open state, the hair that has entered the ejection port is pulled while being sandwiched between the sealed ejection ports.

The present invention was mainly devised to solve these problems, and its technical problem is to eliminate the opening / closing operation of the medicine injection port formed between the ball or the like and the tip of the cylindrical body during use. An object of the present invention is to provide a drug injection container in which hair does not get caught in the injection port.

[0008]

The present invention provides a container body,
It was composed of an assembly member, a ball and a guide member.

The container body has a valve mechanism and a nozzle at the upper end for spraying a drug as an internal solution, and the assembling member has an assembling stepped portion that is locked to the nozzle upper end surface of the container body. The lower part is attached to the nozzle, and a first passage through which the drug sprayed from the nozzle passes is formed in the lower part,
It has a structure in which a plurality of spherical arc-shaped ridges with a spherical arc shape are formed in the upper part, and the ball is attached to the spherical arc-shaped ridge of the assembling member so that the ball arc surface abuts and the upper end is exposed and cannot be pulled out. The guide member is assembled to the upper end of the container body, and has a guide surface that is close to the outer peripheral surface of the assembly member to guide the vertical movement of the assembly member. The space between the plurality of spherical arc-shaped ridges of the member is the second passage communicating with the first passage and the injection port.

In the present invention, the assembling member
The portion facing the scalp may be made of a soft synthetic resin material.

[0011]

In use, when the container body is grasped and the ball is pressed against the scalp during use, the ball and the assembly member are integrally pressed down by the pressing force to press the nozzle and open the valve of the valve mechanism. The drug in the container body is jetted from the nozzle and is vigorously supplied to the scalp from the jet port via the first passage and the second passage.

After or at the same time as the supply, the ball is slid on the scalp to rub the drug on the scalp and massage the scalp. At this time, since the ball has a smooth spherical arc surface,
Smoothly slides on the scalp, effectively exerting rubbing and massage effects.

Further, the spherical arc surface makes a surface contact with an appropriate size on the scalp, and can provide a comfortable massage effect.

At the time of jetting and supplying the medicine to the scalp and when the ball slides on the scalp, the ball and the assembling member are integrally assembled, and only the ball moves up and down as in the conventional case to make the jet port. Since it does not open and close, the problem of hair being caught in the ejection port does not occur.

Since the outer peripheral surface of the assembling member is guided by the guide surface of the guide member, it is possible to perform stable vertical movement.

In the present invention, the assembly member is
When the portion facing the scalp is made of a soft synthetic resin material, the contact with the scalp becomes soft, so that a comfortable feeling is given and there is no risk of damaging the scalp even after repeated use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS.
The container body 1 has a nozzle 7 and a valve mechanism 6 at the upper end thereof, and is configured by a so-called aerosol container that injects a drug that is an internal solution by internal pressure.

The assembling member 2 includes an assembling main body 14 made of a hard synthetic resin which is engaged with the upper end surface of the nozzle 7 by engaging the assembling stepped portion 8 and a soft synthetic resin covering the upper end. It is formed with the covering part 15 made of. The reason why the assembled main body portion 14 is made of hard synthetic resin is to strengthen the assembly with the nozzle 7, and the reason why the covering portion 15 is made of soft synthetic resin is that the scalp 16 is not touched. This is to make it soft.

Normally, only the ball 3 comes into contact with the scalp 16, but the cover 15 frequently comes into contact with the scalp 16 depending on the inclination of the container body 1. Therefore, such a material is used to protect the scalp 16 from strong irritation. I'm using it.

At the lower end of the assembling member 2 (assembling main body portion 14), a first passage 9 through which the medicine injected from the nozzle 7 passes is formed. A wide vertical groove is formed between the four spherical arc-shaped projections 10 of the assembly member 2 (the assembly main body portion 14 and the covering portion 15) to form the second passage 12 communicating with the first passage 9.
And its tip is used as the injection port 13 (see FIG. 3).

In the present embodiment, the vertical groove has a wider groove width to form the second passage 12. However, by setting the width of the vertical groove to be narrow, the injection amount of the medicine is regulated. can do.

The ball 3 is made of metal or synthetic resin, and its spherical arc surface abuts the spherical arc-shaped ridge 10 of the assembling member 2 so that its upper end is exposed integrally and immovably with the assembling member 2. It is assembled, and the second passage 12 is formed by the spherical arc surface of the ball 3 and the vertical groove.

The guide member 4 is assembled to the upper end of the container body 1, and the guide surface 11 which is the inner peripheral surface is located close to the outer peripheral surface of the assembly member 2 to guide the vertical movement of the assembly member 2. To do. The assembling of the assembling member 2 and the nozzle 7 is achieved by merely engaging and fitting, and thus the vertical movement of the assembling member 2 (and the ball 3) is not always stable. By providing the guide member 4, the vertical movement of the assembling member 2 can be stabilized. A cap 5 is attached to the guide member 4.

The use state of this embodiment is shown in FIG. By grasping the container body 1 upside down and pressing the ball 3 against the scalp 16, the integrated body of the ball 3 and the assembling member 2 pushes down the nozzle 7 and opens the valve of the valve mechanism 6, whereby the container body 1 is opened. The drug in 1 is sprayed from the injection port 13 to the scalp 16 through the nozzle 7, the first passage 9 and the second passage 12.

With the spray of this medicine, the ball 3 is moved to the scalp 1.
By sliding on the scalp 6, the scalp 16 is effectively rubbed with the drug and massaged.

EFFECTS OF THE INVENTION Since the ejection port is always in an open state, hair is not bitten and damaged during use, and thus the effect of the drug can be more effectively exerted. Since the part that is in direct contact with the scalp is a spherical arc surface, it can be a surface contact of an appropriate size, can give a comfortable massage effect, and can move smoothly on the scalp. The rubbing and the massage effect of the tip can be made more effective. Since the injection port is formed in the peripheral end portion of the ball, the medicine can be smoothly injected without being disturbed by the scalp, and the ball can immediately rub the scalp. By setting the diameter of the vertical groove, the first passage, the bottom groove, etc. to a desired size, the injection amount of the medicine can be regulated, so that the waste of the medicine can be omitted and an economical injection container can be obtained. it can. By configuring the part of the assembly member that directly contacts the scalp with a soft synthetic resin material, it is possible to soften the contact with the scalp and give a comfortable feeling, and also to damage the scalp even if it is repeatedly used. There is no.
