Abstract

PROBLEM TO BE SOLVED: To know the residual amount of a content, and make it possible to use up the content to the very last by providing a bag to which a valve to discharge the content is attached, and a transparent external container in which the bag is housed, and at the same time, which supports the valve, and housing a pressurized gas between the bag and the external container under a hermetically sealed state. SOLUTION: This aerosol container 1 is a container which discharges various kinds of contents under a mist state, a foam state or a gel state. An external container 2 comprises a transparent plastic or glass or the like, and in the external container 2, a bag 3 which houses a content being pressurized with a propellant or a non- pressurized content, and comprises a single body or mixed resin or the like such as aluminum or polyethylene having flexibility and air-tightness, is housed. In a space formed by the external container 2 and the bag 3, a pressurized gas 5 is housed under a hermetically sealed state, and by this pressurized gas 5, the content and the flexible bag 3 always receive a pressure in the contracting direction. By this constitution, through the transparent external container which is rich in display property, the flexible bag housing the content, or the volume of an internal cylinder can be visually checked, and the residual amount of the content can be easily known.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an anti-inflammatory analgesic, a pest repellent, an antipruritic, a lotion, a deodorant, a hair restorer,
The present invention relates to an aerosol container that discharges various contents such as insecticides, deodorants, bactericides, coolants, dyes, and other pharmaceuticals, cosmetics, household goods, industrial goods, and the like in a spray, foam, or gel form. .

[0002]

2. Description of the Related Art In recent years, products with a design rich in display have been provided by seeing through the inside of various products, but conventional aerosol containers are often made of metal containers such as tin and aluminum. Usually, the container is opaque and the inside of the container is generally invisible.

[0003] Further, unlike a conventional aerosol container, a conventional inner bag and a double-structured container with an inner cylinder for storing a high-viscosity content cannot estimate the remaining amount of the content even if the container is shaken. The end point of use is generally used as a guide depending on the weight, and the judgment of the end point of use of the contents is ambiguous.

[0004]

However, in the above-mentioned conventional example, since the container is opaque, it is impossible to know the remaining amount of the contents until the discharge becomes impossible, and it is impossible to predict the replacement time of the product. There was no problem.

[0005] The present invention is to solve the above-mentioned problems,
The aim is not to provide an aerosol container that allows the inside of the container to be seen through, has a rich display, allows the remaining amount of contents to be known, and allows the contents contained in the container to be used up to the end. It is assumed that.

[0006]

An aerosol container according to the present invention for achieving the above object contains a content pressurized by a propellant or a non-pressurized content, and discharges the content. Has a flexible bag attached thereto, and a transparent outer container that accommodates the bag inside and supports the valve, and a pressurized gas is sealed between the bag and the outer container. It is characterized by being housed.

According to the present invention, since the outer container is transparent as described above, the inside of the container can be seen through and the display is rich, and the flexible container housing the contents via the transparent outer container is provided. By checking the volume of the bag, the remaining amount of the contents can be easily known with a simple configuration.

In addition, the pressurized gas sealed between the flexible bag containing the contents and the outer container pressurizes the flexible bags so as to shrink the flexible bags and discharges the contents. The contents stored in the bag can be used up to the end in order to promote the operation.

In another aspect of the aerosol container according to the present invention, there is provided a flexible inner cylinder for accommodating contents pressurized by a propellant or non-pressurized contents, and accommodating the inner cylinder therein. And a valve for discharging the contents in the inner cylinder, and a pressurized gas is hermetically contained between the inner cylinder and the outer vessel.

According to the present invention, since the outer container is transparent as described above, the inside of the container can be seen through and the display is rich, and the flexible container housing the contents through the transparent outer container can be seen through. By visually checking the volume of the inner cylinder, the remaining amount of the contents can be easily known with a simple configuration.

The pressurized gas sealed between the flexible inner cylinder containing the contents and the outer container is pressurized so as to shrink the flexible inner cylinder. The contents contained in the inner cylinder can be used up to the end in order to promote the discharge of water.

First, the configuration of the first embodiment of the aerosol container according to the present invention will be described with reference to FIGS.
The aerosol container 1 shown in FIG. 1 is used for medicines, cosmetics, household goods such as anti-inflammatory analgesics, pest repellents, antipruritics, lotions, deodorants, hair restorers, insecticides, deodorants, bactericides, coolants, dyes, and the like. In addition, various contents such as industrial supplies are discharged in a spray, foam or gel shape.

The outer container 2 of the aerosol container 1 is made of a transparent plastic, glass, or the like, and the inside of the outer container 2 is a flexible material for storing contents pressurized by a propellant or non-pressurized contents. A bag 3 made of a single or mixed synthetic resin such as aluminum, polyethylene, nylon, and eval having airtightness is accommodated. The bag 3 may have a single layer or a structure in which a plurality of layers are stacked.

A liquefied gas or a compressed gas is appropriately employed as the propellant. As the liquefied gas, liquefied petroleum gas (LPG) such as propane gas or butane gas, ethers such as dimethyl ether, and fluorocarbons such as fluorocarbon, chlorofluorocarbon, and bromochlorofluorocarbon can be used.

Further, as the compressed gas, nitrogen gas, carbon dioxide gas alone or mixed gas, compressed air, nitrous oxide gas and the like can be applied.
