However, in an aerosol container made of a metal material such as aluminum, it is impossible to produce a transparent part in the body part, and it is impossible to make a hole of a certain area in the body part. And it is not appropriate in terms of pressure resistance. Furthermore, in the case of a double aerosol container, an aluminum inner cylinder is inserted into the double aerosol container, and the contents are filled in the aluminum inner cylinder. Was impossible. Therefore, in the conventional double aerosol container, there is no method for checking the remaining amount of the contents, and when the contents are a hair dye, the hair dye disappears during use of the hair dye, and the hair is dyed. There was a drawback that the remaining part was made. The present invention has been made paying attention to such a conventional problem, and provides an apparatus that can easily measure the remaining amount of a hair dye or the like filled in a double aerosol container. Objective.

It is possible to measure the remaining amount of the hair dye in the double aerosol container. Accordingly, it is possible to prevent the hair dye from being lost in the middle of the hair dyeing. When the hair dye is insufficient, the hair dyeing work can be performed after replenishment.

  Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 are drawings showing a first embodiment according to the present invention. Reference numeral 1 denotes a content remaining amount confirmation device, and the content remaining amount confirmation device 1 is shown as an embodiment mounted on a comb 2. In the content remaining amount confirmation device 1, a cylinder 3 is formed of a cylindrical or quadrangular cylindrical transparent synthetic resin case, and a piston 4 and a spring body 5 are inserted into the cylinder 3, and a spring The upper end of the body 5 is connected to a top plate 6 fixed to the upper end portion of the cylinder 3, and the lower end of the spring body 4 is connected to the piston 4. A scale is attached to the surface of the cylinder 3 so that the rising position of the piston 3 can be visually observed. In a state where the pressure of the contents is not applied, the piston 4 is in contact with the sleeve 7. The sleeve 7 is formed with an insertion portion 7a into which the stem 11 of the double aerosol container 10 is fitted, and a communication hole 7b through which a propellant gas that is the pressure of the content from the stem 10a passes. As shown in FIG. 3, a support plate 8 is mounted below the cylinder 3, and the support plate 8 mounted with the cylinder 3 is inserted into a fitting groove 9 a of a fixing portion 9 formed below the comb 2. By doing so, it is fixed in the comb 2. The cylinder 3 may be entirely made of metal, or the main body may be made of metal, and a part thereof may be made of a transparent synthetic resin. Moreover, although the spring body 5 is a compression spring in the embodiment of the drawings, a tension spring can also be used. In this case, the remaining amount of the contents in the double aerosol container 10 can be confirmed by the piston 4 observing the extent of extension of the spring body 5.

FIG. 4 is a drawing showing an embodiment outside the scope of the present invention. Reference numeral 11 denotes a content remaining amount confirmation device, which shows an embodiment in which the content remaining amount confirmation device 11 is a single device. In the content remaining amount confirmation device 11, a cylinder 13 is formed of a cylindrical or quadrangular cylindrical transparent synthetic resin case, and a piston 14 and a spring body 15 are inserted into the cylinder 13, and a spring The upper end of the body 15 is connected to a top plate 16 fixed to the upper end portion of the cylinder 13, and the lower end of the spring body 14 is connected to the piston 14. A scale is attached to the surface of the cylinder 13 so that the position where the piston 13 ascends is visible. The piston 14 is in contact with the sleeve 17 in a state where the pressure of the contents is not applied. The sleeve 17 is formed with an insertion portion 17a at the bottom so that the stem 10a of the double aerosol container 10 can be fitted therein, and a communication hole 17b through which a propellant gas as the pressure of the contents passes from the stem 10a. The difference from the first embodiment is that the content remaining amount confirmation device 11 of the second embodiment is not attached to a comb or the like but exists as a single device. The cylinder 3 may be entirely made of metal, or the main body may be made of metal, and a part thereof may be made of a transparent synthetic resin. Moreover, although the spring body 15 is a compression spring in the embodiment of the drawings, a tension spring can also be used.

FIG. 5 is a drawing showing the position of the piston 4 in the cylinder 3 when the remaining amount of the contents in the double aerosol container is large. In a double aerosol container having an inner cylinder inside, an inner cylinder is filled with a hair dye or the like as a content. In such a double aerosol container, when the remaining amount of the content is large, the injection pressure of the content is strong, so that the piston 4 is pushed up to a site far from the upper end of the sleeve 7. In FIG. 5, for example, the distance L. FIG. 6 is a view showing the position of the piston 4 in the cylinder 3 when the remaining amount of the contents in the double aerosol container is small. In the double aerosol container, when the remaining amount of the content is small, the injection pressure of the content is weak, so that the piston 4 is pushed up to a portion near the upper end of the sleeve 7. In FIG. 6, for example, the distance S. Thus, the remaining amount of the contents in the double aerosol container can be known from the state of the internal pressure. If there is a piston at the α scale position, the remaining amount of the contents in the double aerosol container is large. Conversely, if there is a piston at the β scale position, the remaining amount of contents in the double aerosol container is It is possible to judge that there are few. Therefore, the user of the hair dye can easily confirm this. If the cylinder 3 is made of metal and has a scale on the surface of the cylinder 3, the arrow indicates the scale, and the position of the inner piston can be confirmed, the cylinder 3 need not be transparent. Good.
