Description

[Detailed description of the invention]

[0001]

The present invention relates to a double aerosol container. More specifically, the present invention relates to a double aerosol container in which only the presence or absence of contents can be easily confirmed by shaking the container by adsorbing a liquid portion of the propellant agent with a liquid gas adsorption member.

[0002]

2. Description of the Related Art Conventionally, a double aerosol container having a built-in free piston for hermetically separating the interior of a container into an upper compartment and a lower compartment, or a double aerosol container comprising an outer container and a flexible inner container. Etc. are known. In these double aerosol containers, for example, in the former, the upper compartment is filled with contents such as insecticide, paint, and hairdressing agent to be sprayed, and the lower compartment is filled with the contents of the upper compartment via a free piston. It is filled with a propellant for pressing. On the other hand, in the latter, the contents are filled in the inner container, and the space between the inner container and the outer container is filled with the propellant agent.

[0003] The propellant agent can be selected from various types. For example, chlorofluorocarbon gas, liquefied natural gas, dimethyl ether and a mixture thereof are used, and they are filled in a liquid state under pressure.

[0004] On the other hand, since an external container (container main body in the case of a built-in free piston) as a pressure-resistant member is generally made of a material that dislikes sunlight or artificial illumination light, it is made of a metal or an opaque synthetic resin. Is formed.

[0005]

In such a conventional double aerosol container, it is impossible to visually check the contents and the propellant agent. Since the liquefied propellant agent is used, the sound of the liquid can be heard by shaking the container even if the contents are completely consumed and the jetting is stopped. Therefore, it is extremely confusing for a user who does not know that the liquefied propellant is used. Furthermore, in the event that the aerosol valve breaks down, there is also a problem that the container is discarded as it is because it is not ejected despite the remaining contents.

The present invention has been made to solve such a problem, and it is possible to easily judge whether or not the contents inside the container have been consumed only by shaking the container. It is an object of the present invention to provide a double aerosol container capable of judging the remaining amount of the contents, though specifically.

[0007]

SUMMARY OF THE INVENTION A double aerosol container of the present invention has a first compartment for containing contents to be jetted by a movable partition wall, and pressurizes the first compartment. For containing a propellant agent for the second
It is characterized in that it is airtightly divided into a compartment and a liquid gas adsorption member is sealed in the second compartment.

The liquid gas adsorbing member may be composed of a sea surface material, a fibrous material, a liquefied gas gelling agent, or the like.

[0009]

In the double aerosol container of the present invention (hereinafter simply referred to as "double container"), a liquid gas adsorbing member (hereinafter simply referred to as "adsorbing member") is sealed in a second compartment filled with a propellant agent. Therefore, the liquid portion of the propellant agent is all adsorbed by the adsorbing member. Therefore, even if the user shakes the double container, the liquid level of the propellant does not undulate, and no noise is generated. Then, when the pressure is reduced by injecting the contents, the propellant agent evaporates without any trouble, and the contents in the first compartment can be satisfactorily pressurized.

Therefore, when the double container is shaken, only the content emits a sound of the liquid material, so that the remaining content can be easily confirmed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a double container according to the present invention.

FIG. 1 is a partially cutaway front view showing an embodiment of the double container of the present invention, and FIG. 2 is a partially cutaway front view showing another embodiment of the double container of the present invention.

In FIG. 1, reference numeral 1 denotes a double container, which comprises a main body 2, an aerosol valve 3, a piston 4, and an adsorbing member 5.
And a check valve 6.

The main body 2 is a publicly known one, and is made of metal such as aluminum or a tin plate, or is made of an opaque synthetic resin.

On the other hand, an aerosol valve 3 is also known,
By pushing or tilting the valve stem 7 downward, the contents are spouted from the spout.

The piston 4 can slide freely in the main body 2 in the axial direction, and the interior of the main body 2 is airtightly partitioned into an upper compartment 8 and a lower compartment 9. The upper compartment 8 is filled with contents such as a hairdressing agent, a paint, and a pesticide, and the lower compartment 9 is filled with a propellant agent for pressurizing the contents.

The check valve 6 contains a propellant agent in the main body 2.
This is for injecting into the inside, and a known one can be used.

As described above, a liquefied gas having a low boiling point such as Freon gas, liquefied natural gas, dimethyl ether or a mixture thereof is used as the propellant agent.

The adsorbing member 5 absorbs and adsorbs the liquid portion of the injected propellant agent. Although various structures and shapes of the suction member 5 can be considered,
For example, spongy materials, fibrous materials such as felt, and gelling agents for liquefied gas are preferable.

The material of the adsorbing member 5 can be appropriately selected according to the type of the propellant agent. In the case of a sea surface material or a fibrous material, a material having excellent chemical resistance and rich in flexibility is preferable. For example, the material of the sea-like material includes polyethylene and a sponge made of polyethylene, and the fibrous material includes absorbent cotton and felt. As the gelling agent for a liquefied gas, for example, a metal soap, a fine powdered inorganic metal, or a thickener such as hydroxycellulose is selected.

The double container 11 shown in FIG. 2 is provided with a flexible internal container 12 instead of the piston 4 in the embodiment (FIG. 1). That is, the space between the main body 2 constituting the outer container and the inner container 12 is filled with the propellant agent, and the inner container 12 is filled with the contents. When the contents are ejected by the aerosol valve 3, the inner container 12 is crushed in order to balance the pressure between the contents and the propellant agent, and the inner volume of the inner container 12 is reduced.

In the case of this double container 11, the same adsorbing member 5 as in the above embodiment (FIG. 1) is mounted in the space between the main body 2 and the internal container 12.

In the case of the gas adsorbing member 5 made of a solid such as sponge or fibrous material, when the gas adsorbing member 5 is formed of a material having high flexibility and the contents and the propellant agent are filled. It may be mounted in a compressed state. Then, with the consumption of the contents, the volume of the propellant agent (FIG. 1)
In this case, the suction member follows even when the lower compartment 9 is enlarged, so that the noise reduction effect on the propellant when the double container is shaken is improved.

[0024]

[Effects of the Invention] The double container of the present invention allows the presence or absence of contents to be confirmed simply by shaking. In addition, the remaining amount of the contents can be roughly estimated. The double container of the present invention is extremely effective when a metal plate or an opaque synthetic resin needs to be used as a main body.
