[Structure] The inside of the main body 2 of the double container 1 has an upper compartment 8 for accommodating the contents by a free piston 4 and a lower compartment 9 for accommodating a propellant agent for pressurizing the upper compartment 8. It is airtightly divided, and a liquid gas adsorption member is enclosed in the lower compartment 9.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

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

[0002]

[Prior Art]

 Conventionally, a double aerosol container containing a free piston that air-tightly separates the inside of the container into an upper compartment and a lower compartment, or a double aerosol container composed of an outer container and a flexible inner container is known. ing. These dual aerosol containers, for example, in the former case, the upper compartment is filled with the contents of insecticide, paint, hair styling agent, etc. 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 agent for applying pressure. 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.

The propellant agent can be selected variously, and for example, CFC gas, liquefied natural gas, dimethyl ether or a mixture thereof is used, and is pressurized and filled in a liquid state.

On the other hand, an external container (a container body in the case of a built-in free piston) which is a pressure resistant member is generally made of a metal or a non-translucent synthetic resin because its contents generally hate sunlight and artificial illumination light. Has been formed.

[0005]

[Problems to be solved by the device]

 In such a conventional double aerosol container, it is impossible to visually confirm the contents and propellant agent. Also, since a liquefied propellant is used, even if the contents are completely consumed and it does not spout, the sound of the liquid can be heard by shaking the container. Therefore, this is confusing for users who do not know that they are using liquefied propellant. In addition, if the aerosol valve should malfunction, the container will be discarded as it is because it will not be ejected despite the remaining contents.

The present invention has been made to solve the above problems, and it is possible to easily determine whether or not the contents inside the container are completely consumed by shaking the container. The aim is to provide a double aerosol container that can be used to determine the remaining amount of the content, although it is sensuous.

[0007]

[Means for Solving the Problems]

 The double aerosol container of the present invention has a movable partition wall for containing a first compartment for containing a content to be sprayed and a propellant agent for pressurizing the first compartment. It is characterized in that it is airtightly divided into a second compartment and a liquid gas adsorption member is enclosed in the second compartment.

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

[0009]

[Action]

 In the dual aerosol container of the present invention (hereinafter, simply referred to as a double container), since the liquid gas adsorbing member (hereinafter, simply referred to as an adsorbing member) is enclosed in the second compartment filled with the propellant agent, All the liquid part of the propellant is adsorbed on the adsorption member. Therefore, even if the user shakes the double container, the liquid level of the propellant agent does not undulate, and the sound of chap-on-chappon does not occur. When the pressure is reduced by injecting the content, the propellant agent is evaporated without any trouble and the content in the first compartment can be satisfactorily pressurized.

Therefore, since only the contents make a sound of the liquid substance when the double container is shaken, it is possible to easily confirm the remaining contents.

[0011]

【Example】

 Next, the double container of the present invention will be described with reference to the accompanying drawings.

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 is composed of a main body 2, an aerosol valve 3, a piston 4, a suction member 5, and a check valve 6.

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

On the other hand, the aerosol valve 3 is also known, and the contents are ejected from the ejection port by pushing or tilting the valve stem 7 downward.

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

The check valve 6 is used to inject the propellant into the main body 2, and a publicly known one can be used.

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

The adsorbing member 5 is for absorbing and adsorbing the liquid portion of the injected propellant agent. Although various structures and shapes of the adsorption member 5 are possible, sponge-like materials, fibrous materials such as felt, or gelling agents for liquefied gas are preferable.

The material of the adsorbing member 5 can be appropriately selected according to the type of propellant, but in the case of a sea surface material or a fibrous material, a material having excellent chemical resistance and flexibility is preferable. .. For example, polyethylene or polyethylene sponge may be used as the material for the surface material, and absorbent cotton or felt may be used as the material for the fibrous material. Further, as the gelling agent for liquefied gas, for example, metallic soap, finely powdered inorganic metal, or thickening agent such as hydroxycellulose is selected.

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

Also in the case of this double container 11, the adsorption member 5 similar to that of the above-mentioned embodiment (FIG. 1) is mounted in the space between the main body 2 and the inner container 12.

In the case of the gas adsorbing member 5 made of a solid material such as a spongy material or a fibrous material, if the gas adsorbing member 5 is made of a material having high flexibility, the content and the propellant agent are filled. It may be mounted in a compressed state. Then, even if the volume of the propellant agent (corresponding to the lower compartment 9 in Fig. 1) increases with the consumption of the contents, the adsorbing member follows the propellant agent. The sound-deadening effect against is improved.

[0024]

[Effects of the Invention] The double container of the present invention allows the presence or absence of the contents to be confirmed simply by shaking. In addition, the remaining amount of 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 the main body.
