[0013]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment according to the present application, in which an aerosol container main body 1 and a storage chamber 2 are integrally formed, and a continuous aerosol container with a storage chamber. In this embodiment, the thicknesses of the aerosol container main body 1 and the storage chamber 2 are substantially the same. The manufacturing method is to form a bead portion 3 by necking the opening of a bottomed cylindrical container manufactured by a conventionally known impact molding method, and then to form a bead portion 3 on the bottom of the aerosol container main body 1. The storage chamber 2 is formed in the aerosol container body 1 by drawing. In this embodiment, the aerosol container body 1 is formed by integral molding.
And the storage chamber 2 are continuous with each other, so that there is an advantage that the contents do not leak as compared with the aerosol container with a storage chamber of the fastening type shown in FIG. 2 below.

FIG. 2 shows a second embodiment according to the present application, in which an aerosol container main body 4 and a storage chamber 5 are separately formed, and then each is wound up later. The wall thickness of the aerosol container body 4 and the storage chamber 5 may be the same or different. The manufacturing method of this embodiment is to cut the bottom of the bottomed cylindrical aerosol container body manufactured by a conventionally known impact molding method, to form a winding edge,
On the other hand, a neck portion is formed on the opening to form a bead portion 6. Then, a metal plate is separately drawn and the edge 7 of the storage chamber 5 formed into a cup shape is fixed by winding it under the body of the aerosol container body 4.

FIG. 3 shows a third embodiment according to the present application, in which a bead portion 11 and a body upper portion 12 of an aerosol container 10 are formed to be thin, and are connected to a body base 13 and the body. This is an aerosol container with a storage chamber in which the top surface 15 and the outer peripheral wall 16 of the storage chamber 14 are formed thick.
The feature of this embodiment is that the upper part 12 of the body of the aerosol container body 10 is formed to be thin, and the body base 13 and the storage chamber 1 are formed.
4 is formed thick. 2. Description of the Related Art Conventionally, when processing an aerosol container, it is known that a load equal to or more than a certain value is applied in an axial direction. If the entire body and bottom are made thick to withstand this axial load, there is a disadvantage that the material is wasted more than necessary.

On the other hand, if the entire body and bottom are formed to be thin to save material, the aerosol container main body is subjected to an axial load when processing the bead and clinching the aerosol valve. There was a problem that the bottom of 10 was buckled. In this embodiment, the present inventors form the trunk base 13 to which a large load in the axial direction is applied to a large thickness, and form the trunk upper portion 12 at a portion where other axial loads are not so affected to be thin. Focusing on the fact that the material of the aerosol container body 10 can be saved, the inventor has devised an aerosol container with a storage chamber and a method of manufacturing the same. Specifically, the body upper part 12 formed thinly
Is 70% or more of the thickness of the thick body base 13.
It is desirable that the thickness be reduced in the range of 95%. The thickness of the storage portion 14 is substantially equal to or slightly thicker than the body base portion 13. For example, in the case of an aerosol container having an outer diameter of 40φ, the thickness of the upper part of the body is 0.35 mm, and the thickness of the base 13 of the body is 0.45 mm (thickness of the upper part of the body / thickness of the body part × 100). (≒ 78%), it was found that it was possible to sufficiently withstand the axial load applied during processing.

FIG. 4 shows a fourth embodiment according to the present application, in which an outer peripheral wall 16 of a storage chamber 14 formed in the aerosol container body 10 of the third embodiment according to the present application.
And an engagement groove 17 is formed in the groove. Note that FIG.
As shown in FIG. 5, a convex portion of the bottom cover 33 is fitted into the engagement groove 17 in order to seal an article stored in the storage chamber 14.

FIGS. 5 to 9 are views showing a manufacturing process of the aerosol container body 10 according to the third embodiment. FIG. 5 is a cross-sectional view showing a case where an aluminum slag is impact-molded to form a bottomed cylindrical container 20a in the impact step. Bottomed cylindrical container 2 formed in this step
The thickness of 0a is such that all portions are formed to have substantially the same thickness, or the bottom portion 19 is configured to be slightly thicker than other portions.

Next, FIG. 6 is a sectional view showing a state in which the drawing and ironing process is performed on the bottomed cylindrical container 20a formed in FIG. That is, an ironing punch 22 having a step 21 composed of a large-diameter portion (X) and a small-diameter portion (Y) is inserted from above into the inner surface of a bottomed cylindrical container 20 a, and between the die and die 23. The drawing and ironing process is performed. The feature of the manufacturing process shown in FIG. 6 is that, using an ironing punch 22 having a step 21, a bottomed cylindrical container 20a having a body part upper part 12 and a body part lower part 18 having a partly thin thickness. Is molded. In this process,
The die ring 23 uses a die 23 conventionally used for drawing and ironing, and is drawn and ironed with an ironing punch 22 having a step 21.
Finally, as shown in FIG. 7, the trunk upper part 12 is formed to be thick and the trunk lower part 18 is formed to be thin. In addition, the step 21 can be formed at any position of the can length of the bottomed cylindrical container 20a. That is, it can be determined according to the height of the storage room 14.

Next, FIG. 8 is a sectional view showing the aerosol container main body 20 when the bead portion 24 is formed on the mouth portion by necking. In this step, in order to adjust the height dimension of the aerosol container main body 20, trimming processing is performed to trim the opening ends of the aerosol container main body 20, and then the cleaning step, the inner surface coating step, and the printing step are performed. The bead portion 24 is formed by necking the mouth. Note that the order of the manufacturing steps of the trimming step, the cleaning step, the inner surface coating step, and the printing step is not limited to the above order, and the order can be appropriately changed.

FIG. 9 is a cross-sectional view showing a process of reverse drawing the aerosol container body 20 after the above-described trimming process, cleaning process, inner surface coating process, printing process, and necking process. Bottom 19 with reverse drawing punch 25,
It is pressed into the inside of the aerosol container body 20 to perform reverse drawing. At this time, the central protruding portion 25a of the reverse drawing punch 25 pushes the bottom portion 19 to form the storage chamber 14, and the side portion of the aerosol container body 20 is guided by the surrounding guide portion 25b, so that the reverse drawing process is performed. Is applied.

Next, a specific embodiment of the aerosol container with a storage chamber is shown in FIGS. 10 and 11. FIG. FIG. 10 is a cross-sectional view in which another aerosol container 30 is inserted into the storage chamber 14 formed in the aerosol container main body 20. When displayed in a store or the like, the hairdressing agent, cosmetics, etc., which are used simultaneously, are stored in the storage room 14
In addition, another aerosol container 30 can be integrated and displayed in a state of being inserted.

FIG. 11 shows a specific embodiment in which a substance different from the substance stored in the aerosol container body 20 is stored in the storage chamber 14. For example, it is a drawing showing an embodiment in which the comb 32 is stored. A bottom lid 33 is fixed to the opening of the storage chamber 14 by being locked by an engagement groove 17. In addition to the combs, it is also possible to store a creamy cosmetic or the like, or a heating element (chemical substance) for heating the contents stored in the aerosol container main body 20.
