Abstract

PURPOSE:To make it possible to fill a propellant from the bottom side of a mounting cup by forming a horizontal flange part which is pinched in an upside- down U-shaped groove of a mounting cup, and a rising flange part which comes into contact with the outer peripheral edge of the upside-down U-shaped groove from the outer periphery, at an opening of an internal cylinder main body. CONSTITUTION:A rising flange 7 comes into contact with an outer peripheral edge 4b of an upside-down U shaped groove 4a from the outside, and vertically rises such as covering the upside-down U-shaped groove 4a. Therefore, when a propellant is filled, the rising flange 7 which is in contact with the outer peripheral edge 4b of the upside-down U shaped groove 4a is pressed from the outside by a jig 9, and the outer peripheral edge 4b and the rising flange part 7 are firmly joined. Thus, after preventing the propellant from mixing in a content 11 from a gap between the upside-down U shaped groove 4a and a horizontal flange part 6, a mounting cup 4 and the horizontal flange part 6 are lifted by filling pressure, and the propellant is filled in a space 10 between a container main body 1 and an internal cylinder main body 5, from a gap between a bead part 2 and the horizontal flange part 6. The filling pressure at this time is 40kg-60kg.

The functions of this device, which has a configuration with five or more functions, will be explained. The rising flange portion 7 of the inner cylinder of the double aerosol container according to the second invention contacts the outer peripheral edge 4b of the inverted U-shaped groove 4a from the outside, and rises vertically so as to cover the inverted U-shaped groove 4a. . Therefore, when filling propellant, as shown in FIG. The part 7 is firmly attached. After preventing the propellant from entering the contents 11 through the gap between the inverted U-shaped groove 4a and the horizontal flange portion 6, the mounting cup 4 and the horizontal flange portion 6 are lifted up by the filling pressure, and the propellant the gap between the bead part 2 and the horizontal flange part 6, and the container body 1.
The gap 10 between the inner cylinder body 5 and the inner cylinder body 5 is filled. The filling pressure at this time is 40 kg to 60 kg. Note that by designing the rising flange portion 7 to be in close contact with the outer peripheral edge 4b of the inverted U-shaped groove 4a, it is also possible to fill the propellant without contacting the jig 9 from the outside. After a certain amount of propellant has been filled into the container body 1, as shown in FIG.
Clinch to the lower side of the bead portion 2 of the container body 1 (the state of the side surface of the cup after clinching is shown by the two-dot chain line in FIG. 3).

1 to 3 are drawings showing an embodiment of this invention. 1 and 3 are drawings showing a first embodiment of this invention, in which a straight shape is formed in the container body 1 from the base of the flange portion 3 of the inner cylinder body 5 to the lower part. The inner cylinder main body 5 is inserted. The second inner cylinder main body 5 is made of flexible aluminum foil or synthetic resin material, and the inner cylinder main body 5 is filled with a content 11 to be sprayed to the outside.

Further, a flange portion 3 is formed at the opening of the inner cylinder body, and this flange portion 3 is sandwiched between the inverted U-shaped groove 4a of the mounting cup 4 and the bead portion 2 of the container body 1. It consists of a horizontal flange portion 6 and a rising flange portion 7 that is continuous with the horizontal flange portion 6 and is vertically bent upward. The rising flange portion 7 is formed to be slightly larger than the outer diameter of the inverted U-shaped groove 4a or to be in close contact with the outer circumferential edge 4b so as to contact the outer circumferential edge 4b of the mounting cup 4 from the outside.

FIG. 2 is a drawing showing a second embodiment of the present invention, and the difference from the structure of the first embodiment is that a plurality of outer ribs 8a are formed on the outer periphery of the inner cylinder body 5 below the opening. It is in the point where it was done. The plurality of outer ribs 8a temporarily engage with the bead portion 2 so that the cup side surface of the mount cup 4 is smoothly fitted into the opening of the inner cylinder main body 5. Then, when the mounting cup 4 is finally pressed and inserted into the container body 1, the outer rib 8a
is also inserted into the container body 1.

In addition, the propellant is used to lift the inverted U-shaped groove 4a and the horizontal flange 6 of the mounting cup 4 by the filling pressure of the propellant immediately before the cup side surface of the mounting cup 4 is clinched to the bead 2, thereby clinching the bead. It is filled into the container body 1 through the gap between the portion 2 and the horizontal flange portion 6. Furthermore, the formation of the outer ribs 8a has the following advantages. That is, mounting cup 4
During the clinch, the opening of the inner cylinder main body 5 is pushed outward by the clinch claw together with the cup side surface of the mounting cup 4, but the inner cylinder main body 5 is expanded by the amount that the outer rib 8a bulges outward. Since the diameter of the inner cylinder body 5 is widened, the inner cylinder main body 5 expands outward with a margin. Therefore, it has a unique effect of preventing cracks from occurring in the inner cylinder main body 5 during clinching.

In addition, there is no fear of propellant leakage and the propellant can be easily filled. Further, the double aerosol container with a suspended inner cylinder according to the present invention has the advantage of low manufacturing cost since it is not necessary to drill a bottom hole and fit a valve body.
