Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol container, and more particularly to an aerosol container having a function of causing a nozzle to vibrate during use.

[0002]

2. Description of the Related Art In general, an aerosol container is filled with a propellant gas together with contents in a container body, and is urged by the propellant gas by operating a nozzle disposed on a stem provided on the container body. The contents are ejected from the nozzle. In particular, in the case of an aerosol container containing a hair restorer, a hair restorer, a hair styling agent, a hair dye, and the like, the tip of the nozzle is brought into contact with the scalp or the hair and pressed or patted, so that the hair restorer has an area larger than the nozzle area. There is a configuration in which the contents such as are sprayed and the scalp is massaged. Also, there has been provided an aerosol container configured to generate vibration in the nozzle using the pressure of the injection gas injected from the nozzle, thereby generating a massage effect.

[0003] Usually, a nozzle provided in this type of aerosol container has, as disclosed in, for example, Japanese Patent Application Laid-Open No. 9-47690, a hollow portion which is concave in a portion facing the scalp of the nozzle. Is formed. Therefore, when the nozzle is pressed against the scalp, this space is a closed space. Therefore, when the contents and the propellant gas are injected into the closed space, the contents and the propellant gas leak out of the nozzle from between the nozzle and the scalp due to the injection pressure of the contents and the propellant gas. At this time, vibration occurs in the nozzle,
The above-described aerosol container having a massage function is configured to massage the scalp using this vibration.

[0004]

However, in the conventional aerosol container having a massage function, a sufficient massage effect cannot be obtained (vibration is weak), and on the contrary, the massage effect is too strong. Further, although a massage effect can be obtained, there are problems that the contents are scattered more than necessary and that the contents cannot be jetted to a desired position.

[0005] The present invention has been made in view of the above points, and has as its object to provide an aerosol container that can achieve an appropriate massage effect on a portion to be jetted and can improve the usability.

[0006]

Means for Solving the Problems To solve the above problems, the present invention is characterized in that the following means are taken. According to the first aspect of the present invention, there is provided a container main body having a stem filled with contents composed of a propellant gas and a propellant and having a valve opening operation when operated, and disposed on the stem. A contacting portion that contacts the portion to be ejected, a space having a concave shape formed on a surface opposite to the fitting position with the stem, and an injection that communicates the space with the stem. And an ejection nozzle having a hole, by ejecting the contents by contacting the ejection nozzle with the injection target portion, whereby the aerosol container configured to generate vibration in the ejection nozzle, When the volume of the space formed in the valve is 0.45 ml, the injection amount of the contents for 10 seconds is from 5.0 g to 1 g.
It is characterized in that it is set in the range of 6.0 g.

[0007] Further, the invention according to claim 2 is a container body having a stem filled with contents composed of a propellant gas and a propellant, and having a stem which operates to open a valve when operated. A contact portion that is disposed on the stem and abuts on the portion to be ejected, a space portion having a concave shape formed on a surface opposite to a fitting position with the stem, and the space portion and the stem. And an ejection nozzle having an ejection hole that communicates with the ejection nozzle, and the ejection nozzle is brought into contact with the injection target portion to eject the content, thereby generating vibration in the ejection nozzle. In the aerosol container, the volume of the space formed in the valve is 1.26 m.
l, the injection amount of the contents for 10 seconds is 9.0 g
From 19.5 g to 19.5 g.

[0008] The invention according to claim 3 is a container body having a stem filled with contents composed of a propellant gas and a propellant and having a valve opening operation when operated. A contact portion that is disposed on the stem and abuts on the portion to be ejected, a space portion having a concave shape formed on a surface opposite to a fitting position with the stem, and the space portion and the stem. And an ejection nozzle having an ejection hole that communicates with the ejection nozzle, and the ejection nozzle is brought into contact with the injection target portion to eject the content, thereby generating vibration in the ejection nozzle. Aerosol container, the volume of the space formed in the valve is 0.45 m
When the amount is set in the range of 1 to 1.26 ml, the injection amount of the contents for 10 seconds is set in the range of 9.0 g to 16.0 g.

According to the first to third aspects of the present invention, the injection nozzle is fitted to the stem provided on the container body, and by operating the injection nozzle, the injection nozzle is inserted into the container body. The filled content is urged by the pressure of the blast gas and is blasted from the blast nozzle. At this time, the ejection is performed in a state where the contact portion of the ejection nozzle is in contact with the portion to be ejected. Therefore, the space portion having the concave shape forms a closed space between the space portion and the injection target portion. As described above, the content is injected by being urged by the propellant gas into the closed space, so that a gap is formed between the contact portion and the portion to be injected. The object and the propellant gas escape to the outside of the space. When this content comes off, the ejection nozzle vibrates. Therefore, by this vibration, it is possible to achieve a massage effect on the injection target portion by the injection nozzle.

In view of the above-mentioned conventional problems, the present inventor conducted an experiment focusing on the relationship between the volume of the space and the injection amount of the contents, and found that the volume of the space was 0.45 ml. Sometimes one of the contents

By setting the amount within a range of from 16.0 g (claim 3), it is possible to realize an appropriate aerosol effect on the injection target portion and to realize an aerosol container excellent in usability without unnecessary scattering or the like. Was completed.

[0011]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an aerosol container 10A according to a first embodiment of the present invention, and FIG. 2 shows an aerosol container 10B according to a second embodiment of the present invention. In the following description, each of the aerosol containers 10A, 1
An example in which 0B is used as a hair restoration container having the scalp 22 as the injection target will be described.

First, an aerosol container 10 shown in FIG.
A will be described. The aerosol container 10A includes a container body 11, a stem 13, a large-diameter nozzle 17A serving as an injection nozzle, and the like. Container body 1
1 is made of, for example, an aluminum can, and the inside thereof is filled with contents (not shown) composed of a propellant gas and a propellant. In this embodiment, dimethyl ether (DME) is selected as the propellant gas, and the propellant is loaded with a hair restorer, a hair restorer, a hair styling agent, a hair dye, and the like.

The stem 13 is provided on a valve mechanism 14, and the valve mechanism 14 is attached to the center of the mounting cup 12 that covers the upper opening of the container body 11. The stem 13 is configured to swing and move up and down. By performing these operations, the valve mechanism 14 is opened, and the contents are ejected from the upper portion of the stem 13.

The large-diameter nozzle 17A is fixed to the stem 13. The large-diameter nozzle 17A has a fitting hole 18,
It has a configuration having an abutment portion 23A, an injection hole 20, a space portion 21A, and the like. The fitting hole 18 is a hole that fits with the stem 13. Therefore, when the fitting hole 18 fits with the stem 13, the large-diameter nozzle 17 </ b> A is fixed to the stem 13.

The contact portion 23A is a portion which comes into contact with the scalp 22 (see FIG. 5) as a portion to which the contents are to be ejected when used. The shape of the contact portion 23A is a suction cup shape in cooperation with a space portion 21A described later. The space 21A is formed on a surface opposite to the fitting position with the stem 13. In this embodiment, the diameter of the opening of the space 21A (indicated by an arrow R1 in the figure) is about 23 mm, and the volume S1 is 1.26 m.
1 (milliliter).

At the position which becomes the bottom of this space 21A,
Injection hole 20 that communicates this space 21A with stem 13
Are formed. Specifically, the injection hole 20 is formed by the passage 19 formed at the center of the large-diameter nozzle 17A.
Is connected. Therefore, when the valve mechanism 14 is opened by the operation of the stem 13 (that is, the operation of the large-diameter nozzle 17A) as described above, the contents in the container body 11 are urged by the propellant gas to cause the stem 13 and the passage 19 to pass through. The fuel is injected from the injection hole 20 into the space 21A.

Next, the aerosol container 1 constructed as described above
How to use 0A will be described. As shown in FIG. 5, the aerosol container 10A having the above configuration is used with the contact portion 23A of the large-diameter nozzle 17A contacting the scalp 22. Specifically, the user grips the container body 11 of the aerosol container 10A by hand and presses the large-diameter nozzle 17A against the scalp. At this time, by bringing the contact portion 23A into contact with the scalp 22, the upper opening portion of the space 21A is closed by the scalp 22, so that the space 21A forms a closed space.

When the aerosol container 10A is further pressed against the scalp 22 in this state, the stem 13 is operated by the pressing force, and the valve mechanism 14 is opened. When the valve mechanism 14 is opened as described above, the contents (injection gas and injection liquid) are urged by the injection gas filled in the container main body 11, and the contents (injection gas and injection liquid) pass through the stem 13, the passage 19 and the space from the injection hole 20. It is injected into the portion 21A.

However, as described above, the space 21A is
The closed space is formed by bringing the contact portion 23A into contact with the scalp 22. Therefore, this closed space portion 21
When contents (injection gas and injection liquid) having a high gas pressure are injected into A, the internal pressure of the space 21A increases.
Eventually, at any one of the contact positions between the contact portion 23A and the scalp 22, a separation portion is generated between the contact portions 23A and 22. FIG. 3 shows a state in which a separation portion has occurred between the contact portion 23 </ b> A and the scalp 22.

When a space is generated between the contact portion 23A and the scalp 22, the contents flow out of the space from the space (indicated by the arrows in the figure). Thereby, the jet liquid is diffused to the scalp 22. Also, with this outflow,
Vibration occurs in the large diameter nozzle 17A, and this vibration
2 has the effect of massaging. Therefore, the user receives the diffusion of the spray liquid on the scalp 22 and the massage effect at the same time, and can obtain a refreshing feeling.

Next, an aerosol container 10B according to a second embodiment will be described with reference to FIG. The aerosol container 10B is the aerosol container 10A according to the first embodiment.
However, the other configuration is the same except for the shape of the nozzle 17B (hereinafter, referred to as a small-diameter nozzle). For this reason, in FIG. 2, the same components as those of the aerosol container 10A according to the first embodiment shown in FIG. 1 are denoted by the same reference numerals, and the description thereof will be omitted.

The small-diameter nozzle 17B is fixed to the stem 13. This small-diameter nozzle 17B is a large-diameter nozzle 1
7A, the fitting hole 18, the contact portion 23B, the injection hole 20,
And a space 21B and the like. The contact portion 23A is a portion that comes into contact with the scalp 22 during use, and has a bottomed cylindrical shape in cooperation with a space portion 21B described later.

The space 21B is formed on a surface opposite to the fitting position with the stem 13. In this embodiment,
The diameter of the opening of the space 21B (indicated by an arrow R2 in the figure) is about 12 mm, and the volume S1 is 0.45 ml (milliliter). In addition, an injection hole 20 that connects the space 21B and the stem 13 is formed at a position serving as a bottom of the space 21B,
It is configured to be connected to the stem 13 via the passage 19.

In the aerosol container 10B according to the second embodiment, the space 21B is closed by bringing the contact portion 23B into contact with the scalp 22 during use. When contents (injection gas and liquid) having a high gas pressure are injected into the closed space 21B, the internal pressure of the space 21B increases, and the contact portion 23A
A distant site occurs at any of the contact positions between the scalp and the scalp 22, and the contents flow out of the distant portion to the outside. Therefore, according to the same principle as that of the aerosol container 10A according to the first embodiment, vibration is also generated in the aerosol container 10B according to the present embodiment, and a massage effect can be obtained.

By the way, the present inventor has assumed that the same container body 11 is used.
(That is, the injection amount is the same),
It has been found that the feeling of use differs between the case where A is attached and the case where the small diameter nozzle 17B is attached. Therefore, the present inventor has determined that the difference in the feeling of use is due to the fact that each nozzle portion 17A, 1
7B, the volumes of the space portions 21A and 21B formed in
The following experiment was performed assuming that the relationship was related to the amount of the content injected from the container body 11. FIG. 4 shows the results of an experiment performed by the inventor.

The experiment shown in FIG.
7A and a small-diameter nozzle 17B, the container body 1 having different injection amounts.
The aerosol container attached to No. 1 was prepared (Examples A to P were prepared), and the feeling of use when each aerosol container was actually used was determined. The experimental conditions are as follows. Nozzle used ・ Large-diameter nozzle (diameter 23 mm, volume of space 21A 1.
26 ml) ・ Small diameter nozzle (diameter 12 mm, volume of space 21B 0.
45 ml) Average injection amount of container body Average value of weight (g) of contents injected in 10 seconds In this experiment, 3.9 (g / 10 seconds) to 23.6 (g / 1)
0 seconds) 50 wt% (75 g) of the stock solution and 50 wt% (7
5g) is mixed. Container used Aluminum can (50 mm in diameter, 155 mm in height) Measurement of feeling of use The aerosol container of Example A to Example P is actually used for a plurality of persons (20 persons in this experiment). We asked them to check the feeling of use at that time by conducting a questionnaire. Specific questionnaire items are as follows.

-Whether there is a good massage feeling at the time of injection-Whether there is a direct hit to the scalp-Whether there is a feeling that stress is likely to be dissipated-Whether the contents are easily applied to the scalp-The contents are applied to the temporal region・ Easy to use ・ Does the contents scatter more than necessary at the time of injection? Also, if all the people who have conducted the questionnaire evaluate the above questionnaire items as good, the feeling of use is “○”
If more than half of the questionnaire respondents evaluated the above questionnaire as good, the feeling of use is indicated by “△”, and less than half of the questionnaire responded to the questionnaire. When the evaluation was “good”, the feeling of use was indicated by “x”.

Examination of the experimental results shown in FIG.
The following items were found. Large-diameter nozzle 17A (space volume: 1.26 ml)
Is used, the average injection amount of the contents is 9.0 (g / g).
Good use feeling can be obtained in the range of 10 seconds) to 19.5 (g / 10 seconds). Small-diameter nozzle 17B (volume of space: 0.45 ml)
Is used, the average injection amount of the contents is 5.0 (g / g).
Good use feeling can be obtained in the range of 10 seconds) to 16.0 (g / 10 seconds). From the results of the above and the above, the volume of the space is 0.4
When using a 5 ml to 1.26 ml nozzle,
Average injection amount of contents from 9.0 (g / 10 seconds) to ~ 1
A good feeling in use can be obtained in the range of 6.0 (g / 10 seconds).

Therefore, by preparing a nozzle and a container body satisfying the above-mentioned conditions, a proper massage effect can be realized for the injection target portion, and excellent usability without unnecessary scattering or the like is obtained. An aerosol container can be realized.
