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 that discharges contents in a container body by operating a discharge button.

[0002]

2. Description of the Related Art In general, aerosol containers are widely used as containers for cosmetics. FIG. 13 illustrates a schematic configuration of a conventional aerosol container 1. As shown in FIG. 1, the aerosol container 1 has a configuration including an aerosol container main body 2, a discharge button 4, an overcap 5, and the like.

The aerosol container body 2 is filled with contents such as a hairdressing material and a discharge agent (eg, LPG). The valve 3 is a valve body that opens and closes when the stem 6 is pressed, and is configured to close when the stem 6 stands upright and to open when pressed.

The discharge button 4 is formed by resin molding, and has a structure in which a discharge port 7, an operation section 8, a discharge passage 9, and the like are integrally formed. The discharge button 4 is fixed to the aerosol container main body 2 by being fixed to the stem 6.

The discharge port 7 is a part for discharging the contents filled in the aerosol container main body 2 to the outside, and is configured to communicate with the stem 6 by a discharge passage 9 formed in the discharge button 4. I have. Therefore, by pressing the operation portion 8 located above the discharge button 4, the stem 6 opens, and the contents filled in the aerosol container main body 2 are discharged from the discharge port 7 through the discharge passage 9. You.

The overcap 5 is fitted and attached to a mounting cup 10 provided on the upper part of the aerosol container body 2 when not in use (when the aerosol container is not used). The overcap 5 has a cylindrical shape with a bottom, and is configured to cover and protect the discharge button 4 when attached to the aerosol container body 2.

[0007]

As described above, since the valve 3 is configured to discharge the contents when the stem 6 is depressed, some force is applied to the discharge button even if the user does not intend. If it acts on and is pressed, the contents will be discharged. Also, as described above, the overcap 5
Is the mounting cup 10 of the aerosol container body 2
The overcap 5 is easily detached from the aerosol container main body 2 when an external force is applied because the fitting strength is set to a relatively low value of about 5 to 30 N.

Therefore, for example, even when the aerosol container 1 is carried in a bag or the like with the overcap 5 attached, the overcap 5 is detached from the aerosol container body 2 by a slight external force. In this state, since the ejection button 4 is exposed, the content is ejected when the ejection button 4 is pressed by the external force. For this reason, in the conventional aerosol container 1, there was a problem that the inside of the bag was stained, or there was a case where the ejection agent was exhausted before the entire contents were not used.

The present invention has been made in view of the above points, and has as its object to provide an aerosol container that can prevent the contents from being accidentally discharged when not in use.

[0010]

Means for Solving the Problems In order to solve the above problems, the present invention is characterized by taking the following means.

An aerosol container body provided with a discharge button having a discharge port for discharging the contents and an operation section operated at the time of discharging the contents, is provided.
It is composed of a cylindrical body and an upper plate that covers the upper end of the body. The body is disposed so as to cover the discharge button, and is attached to the aerosol container body in a rotatable configuration. An aerosol container comprising a malfunction prevention cap, wherein the malfunction prevention cap has a first opening that allows discharge of the contents in a state facing the discharge port with the rotation, A second opening that allows operation of the operation unit in a state facing the operation unit with the rotation, and the first and second openings are provided only in the body unit; It is characterized by having a configuration.

According to the present invention, since the ejection button is covered by the malfunction prevention cap composed of the cylindrical body and the upper plate covering the upper end thereof, for example, when the portable device is carried, the external force is applied to the aerosol container. Is applied, the external force is received by the malfunction prevention cap and is not applied to the ejection button. Therefore, it is possible to prevent the contents from being erroneously ejected when the aerosol container is not used, for example, when carrying it.

Since the malfunction prevention cap is rotatable with respect to the aerosol container main body, the first malfunction prevention cap provided on the malfunction prevention cap is used when the aerosol container is used.
The opening of the discharge button is opposed to the discharge port of the discharge button, and the malfunction prevention cap is rotated so that the second opening provided in the malfunction prevention cap is opposed to the operation unit. It becomes possible.

Therefore, the malfunction prevention cap is always kept attached to the aerosol container body,
Therefore, it is possible to prevent the overcap from being lost, which has conventionally been caused by the configuration in which the overcap is attached to and detached from the aerosol container body. Also, during use, the ejection operation can be performed without removing the malfunction prevention cap from the aerosol container body,
Operability during use can be improved.

Further, since the first and second openings are provided only in the body, the upper plate does not have any openings. Usually, the discharge button provided on the aerosol container is configured to discharge the contents by being pressed. That is, a malfunction occurs when an external force is applied to the operation unit from above.

However, according to the present invention, the first and second openings are provided only in the body, and the upper plate has no opening. Therefore, the external force applied in the direction of operating the ejection button is received by the upper plate portion, and is not applied to the ejection button. Thereby, even if the first and second openings necessary for discharging the contents are provided in the malfunction prevention cap, the contents are erroneously discharged when the aerosol container is not used, such as when carrying the contents. It can be reliably prevented.

According to a second aspect of the present invention, in the aerosol container according to the first aspect, when the malfunction prevention cap is viewed in a plan view, at least an operation portion of the discharge button is hidden by the upper plate portion. It is characterized by the following.

According to the above invention, even if an external force is applied to the aerosol container from above, the operation portion of the discharge button is completely covered with the malfunction prevention cap. It is not manipulated. Therefore, it is possible to prevent the contents from being erroneously discharged.

The third aspect of the present invention is the first or second aspect.
In the aerosol container described in the above, the operation portion is formed by an inclined surface whose height gradually decreases from a center position of the discharge button toward an outer peripheral position.

According to the above invention, even if the operation of the operation section is performed from the side through the second opening, the operation section is constituted by the inclined surface, so that the operation section can be easily operated. it can. Therefore, even if the second opening is provided in the body, the operability of the operation unit can be maintained high.

[0021]

Next, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 to 6 show an aerosol container 20A according to a first embodiment of the present invention. 1 to 3 show a use state (a state in which a discharging operation is performed) of the aerosol container 20A, and FIGS.
A indicates a non-use state (a state in which the ejection operation is not performed, for example, when the camera is carried).

The aerosol container 20A generally comprises an aerosol container body 22, a discharge button 24A, a malfunction prevention cap 25A, and the like. The aerosol container main body 22 contains, for example, a content such as a hairdressing agent and LP therein.

The discharge button 24A includes an operation section 29A, a stem mounting section 30, a discharge port 32, a discharge passage 33, and the like. The operation unit 29A is provided at the uppermost part of the discharge button 24A, and is used for discharging the contents (hereinafter, referred to as “discharge”).
This time is referred to as the time of use). At a predetermined position on the side surface of the discharge button 24A, there is formed a discharge port 32 for projecting the contents filled in the aerosol container body 22 to the outside during use.

The stem mounting part 30 is formed at the center of the lower part of the discharge button 24A.
The stem 26 provided on the stem mounting portion 30 is configured to be mounted on the stem mounting portion 30 in a liquid-tight manner. This stem mounting part 30
A discharge passage 33 is formed between the discharge port 32 and the discharge port 32. Therefore, when the stem mounting portion 30 is mounted on the stem 26, the stem 26 has a configuration in which the stem 26 communicates with the discharge port 32 via the discharge passage 33. In the above configuration, when the user presses the operation unit 29, the ejection button 24A moves down and the stem 26 is pressed. As a result, the valve 23 is opened, and the contents filled in the aerosol container main body 22 are urged by the discharge agent, and the stem 26,
It is discharged (sprayed) from the discharge port 32 to the outside via the discharge passage 33.

The malfunction prevention cap 25A has a substantially cylindrical shape with a bottom, and when roughly described, a body 35A and an upper plate 36 are formed.
A, a first opening 40A, a second opening 41A, and the like. This malfunction prevention cap 25A
Is configured to be rotatable with respect to the aerosol container body 22 as will be described in detail later.
In the non-use state where OA is not used (for example, when carrying the aerosol container 20A), a function of preventing the malfunction of the discharge button 24A is provided. Hereinafter, malfunction prevention cap 2
Each component of 5A will be described.

The body 35A has a cylindrical shape, and a mounting portion 37A is integrally formed at the lower end. The mounting portion 37A has an annular shape, and is configured to be rotatably mounted on a mounting cup 27 provided on the aerosol container main body 22.

More specifically, a projection 38A projecting inward is provided at the lower end of the inner periphery of the mounting portion 37A, and the projection 38A engages with the mounting cup 27 as shown in FIG. The configuration is as follows. Thereby, the malfunction prevention cap 25A is configured to be rotatable with respect to the aerosol container body 22. In addition, the mounting portion 37A
The engagement force between the aerosol container body 22 and the aerosol container body 22 is set as strong as possible in a range that can be rotated by the user,
It is configured such that the usability preventing cap 25A does not easily rotate while maintaining the usability.

The upper plate portion 36A is provided so as to cover the upper end of the body portion 35A having the above-described structure.
5A is formed integrally with the resin. The upper plate portion 36A is configured to cover substantially the entire surface of the body portion 35A. Therefore, when the malfunction prevention cap 25A is viewed in a plan view as shown in FIG. 1, the discharge button 24A is completely attached to the upper plate portion 36A. It is configured to be hidden.

First opening 40A and second opening 41
A is the same shape and the malfunction prevention cap 25A
Are formed at positions symmetrical to each other with respect to the rotation center axis. That is, the first opening 40A and the second opening 41A are configured to be formed 180 degrees apart.

The first and second openings 40A, 41
A is configured to be formed only on the body portion 35A and not formed on the upper plate portion 36A. Further, the shape and size of each of the openings 40A and 41A are changed according to the rotation of the malfunction prevention cap 25A.
When A and 41A face the discharge port 32, the contents are discharged from the discharge port 32 through the openings 40A and 41A (see FIG. 3), and the openings 40A and 41A are connected to the operation unit 29A. In the opposed state, the user's finger is set to be able to operate the operation unit 29A through the openings 40A and 41A (see FIG. 2). In this embodiment, as shown in FIG. 1, the first and second openings 40A, 4A are provided.
Although the upper end of 1A is configured to be exposed to the upper plate portion 36A, this does not positively form an opening in the upper plate portion 36A.

Next, a method of using the aerosol container 20A having the above structure will be described. Aerosol container 2
In order to discharge the contents from 0A, first, the malfunction prevention cap 25A is rotated with respect to the aerosol container main body 22, so that the openings 40A and 41A are aligned with the discharge ports 32 and the operation section 29A. In the present embodiment, an example is shown in which the first opening 40A and the discharge port 32 face each other, and the operation unit 29A and the second opening 41A face each other.

By opposing the operation section 29A and the second opening 41A, the user can insert a finger into the space 42 through the second opening 41A as shown in FIG. Thus, it is possible to press the operation unit 29A. By pressing the operation portion 29A, the valve 23 is opened, and the contents are discharged from the discharge port 32. At this time, since the first opening 40A faces the discharge port 32, the malfunction preventing cap 25A does not hinder the ejection of the contents, and the malfunction preventing cap 25A
Is provided, the contents can be discharged smoothly.

Next, the case where the aerosol container 20A is not used will be described. When the aerosol container 20A is not used, the malfunction prevention cap 25A is rotated 90 degrees from the use state shown in FIGS. 4 to 6 show a state in which the malfunction prevention cap 25A is rotated by 90 ° with respect to the aerosol container main body 22 in a direction indicated by an arrow C in FIG.

In the non-use state, both the operation portion 29A and the discharge port 32 face the body 35A formed on the malfunction prevention cap 25A. Therefore,
Even if the user attempts to operate the discharge button 24A, the body 35A is in the way and the operation unit 29A cannot be operated, so that erroneous operation of the discharge button 24A by the user can be prevented.

Here, the aerosol container 20 in the unused state is used.
It is assumed that A is carried. As described above, when carrying the aerosol container 20A in a bag or the like, it is possible that some external force is applied to the aerosol container 20A. However, in the aerosol container 20A according to the present embodiment, the ejection button 24A is covered and protected by the malfunction prevention cap 25A.

For this reason, even if the above-mentioned external force is applied to the aerosol container 20A during carrying, the external force is received by the malfunction prevention cap 25A and is not applied to the ejection button. Therefore, when carrying the aerosol container 20 or the like.
In the non-use state of A, it is possible to prevent the contents from being erroneously discharged.

In this embodiment, the first and second openings 40A and 41A are provided only in the body 35A, and are not provided in the upper plate 36A. . Also according to this configuration, malfunction of the discharge button 24A can be reliably prevented. Hereinafter, the reason will be described.

Now, an opening is temporarily provided in the upper plate portion 36A,
It is assumed that the discharge button 24A is operated through this opening. Usually, the discharge button 24A provided on the aerosol container main body 22 is configured to discharge the contents when pressed. That is, when an external force is applied to the operation unit 29A from above, a malfunction occurs.

As described above, the malfunction preventing cap 25A is rotatably attached to the aerosol container body 22, and the malfunction preventing cap 25A is rotated by the user as described above. Therefore, malfunction prevention cap 25A for aerosol container body 22A
Cannot be excessively increased. That is, the malfunction prevention cap 25A may rotate with respect to the aerosol container main body 22 when carrying.

In the case where the unintentional operation of the malfunction prevention cap 25A is caused when the portable device is carried as described above, in the configuration in which the opening is provided in the upper plate portion 36A as described above, the opening and the discharge button 24A are connected. There is a risk of doing it.
When an external force is applied in this state, the external force acts as a force for pressing the discharge button 24A, so that the contents may be erroneously ejected (discharged).

According to the present invention, however, the first and second openings 40A and 41A are provided only in the body 35A (that is, only in the side of the malfunction prevention cap 25A), It is not formed on the portion 36A. Further, the discharge button 24A is completely hidden by the upper plate portion 36A in a plan view.

Therefore, even if the malfunction prevention cap 25A is rotated during carrying, the external force applied in the direction of operating the discharge button 24A is received by the upper plate portion 36A, and is not applied to the discharge button 24A. Absent. This allows
First and second openings 40A, 4 necessary for discharging the contents
Even if 1A is provided on the malfunction prevention cap 25A, it is possible to reliably prevent the contents from being erroneously ejected when the aerosol container 20A is not in use, such as when carrying it.

In this embodiment, even when the malfunction prevention cap 25A is rotated during carrying, the openings 40A and 40B face the discharge ports 32 and the operation section 29A, and even if an external force is applied at this time. This external force is a force for pressing the side portion against the discharge button 24A. Since the direction in which the external force is applied is different from the direction in which the ejection button 24A is pressed, the contents are not erroneously ejected (ejected) even when the external force is applied.

The aerosol container 2 constructed as described above
0A means that the malfunction prevention cap 25A is always attached to the aerosol container body 22. Therefore, the loss of the overcap 5 which has occurred in the conventional configuration in which the overcap 5 is attached to and detached from the aerosol container body 2 (see FIG. 13) can be prevented beforehand. In addition, during use, the ejection operation can be performed without removing the malfunction prevention cap 25A from the aerosol container main body 22, so that operability during use can be improved.

Further, the aerosol container 20 according to the present embodiment
13A and the conventional aerosol container 1 shown in FIG. 13, the same discharge button 24A and conventional discharge button 8 can be used. Therefore, by mounting the malfunction preventing cap 25A according to the present embodiment instead of the conventionally used overcap 5, the aerosol container 20A having the various effects described above can be easily realized.

The first and second openings 40A, 40B
Is formed, the user puts his / her finger on the first or second opening 40A, 40A from the side of the malfunction prevention cap 25A.
The user operates the operation unit 29B via B. In the aerosol container 20A according to the first embodiment described above, for this purpose, a wide space 42 is provided above the discharge button 24A (that is, the shapes of the openings 40A and 40B are increased), and the operability of the discharge button 24A is improved. Was improved.
However, in this configuration, the malfunction prevention cap 25A necessarily becomes taller, and the formability is reduced.

However, even if the discharge button 24B is provided with the tapered operating portion 29B as in this embodiment, the discharge button 24B can be easily operated from the side of the malfunction prevention cap 25A. Can be operated. Further, even if the separation distance between the upper surface of the discharge button 24B and the upper plate portion 36A is shortened, that is, even if the height of the malfunction prevention cap 25A is reduced, the discharge button 24B can be reliably operated. Aerosol container 20B
Can be reduced in size and formability can be improved.

Next, a third embodiment of the present invention will be described.

FIGS. 8 to 12 show an aerosol container 20C according to a third embodiment of the present invention. 8 to 1
0 shows the use state of the aerosol container 20C, and FIGS. 11 and 12 show the non-use state of the aerosol container 20C. 8 to 12, the same components as those of the aerosol container 20A according to the first embodiment shown in FIGS. 1 to 6 are denoted by the same reference numerals, and description thereof will be omitted.

The stem 26 provided on the aerosol container main body 22 is mounted in a stem mounting portion 48 in a liquid-tight manner. Also, the stem mounting portion 48 and the discharge port 49
The nozzles 47 communicate with each other by a discharge passage 50 formed inside.

Therefore, as shown in FIG. 10, when the user operates the operation section 54 of the nozzle section 47 with a finger, the stem 26 is pressed and the valve is opened, and the aerosol container body 2 is opened.
The contents filled in 2 are discharged from stem 26. Further, since the nozzle portion 47 is connected to the stem 26, the contents discharged from the stem 26 are discharged from the discharge passage 5.
It is discharged to the outside from the discharge port 49 through the inside of 0.

The spout 45 has a configuration in which a nozzle portion 47 extends upward from a base portion 46 in order to improve the usability when discharging the contents. Therefore, the aerosol container 2 is exposed in a state where the nozzle portion 47 is exposed.
When the user carries the 0C, an external force easily acts on the operation unit 54. Therefore, when the operation unit 54 is pressed by some external force during carrying, the contents are discharged and the inside of the bag being carried is soiled, and the discharge agent is exhausted before the contents are completely used. Occurs as described above.

For this reason, the aerosol container 20C according to the present embodiment is also provided with a malfunction prevention cap 25B. The malfunction prevention cap 25B according to the present embodiment also includes a body 35B, an upper plate 36B, a first opening 40B, a second opening 41B, and the like.
