Problems solved by technology

That is, the inner bag is generally inserted from the mouth of the metal container, but if the size of the inner bag is reduced in order to easily insert the inner bag from the mouth of the metal container, the filling amount of the contents is limited
On the other hand, if the size of the inner bag is larger than the opening of the metal container in order to increase the filling amount

Embodiment Construction

[0130] figure 1 The manufacturing device 10 of the double aerosol container is equipped with a shrinking machine 11 for forming a bottomed cylindrical container into a metal container, an inner bag inserting machine 12 for inserting an inner bag into the formed metal container, and a shrinking machine for shrinking. The machine-formed metal containers are transported to the conveyor 13 of the inner bag insertion special machine in turn. In addition, reference numeral 14 is a washing machine for washing metal containers, which is a conventionally known machine. In addition, the formed inner bags 30 are sequentially conveyed to the inner bag insertion machine 12 (not shown).

[0131] Such as figure 2 As shown, the necking machine 11 is composed of a rotary disk 21 and a reciprocating disk 22. The rotary disk 21 holds bottomed cylindrical containers (all containers from bottomed cylindrical containers to metal containers that are deformed by molds) intermittently. The recipr...

Abstract

To provide a method for producing a double aerosol container capable of maintaining the quality of an inner pouch by preventing, when the inner pouch is inserted, deformation of the inner pouch and generation of wrinkles and cracks, the double aerosol container having excellent productivity and being producible with low cost. [Solution] A method for producing a double aerosol container comprising: a metal container having a body portion and an opening and/or shoulder portion with the diameter reduced by the body portion; and an inner pouch inserted into the metal container and having a body portion and an opening, a propellant being interposed between the metal container and the inner pouch. This method includes: subjecting an upper part of a bottomed cylinder can supported on a can holder to a drawing process with a plurality of drawing dies, thereby forming a metal container; and then inserting an inner pouch into the metal container by using a dedicated inner pouch inserting device provided with an insertion rod that moves reciprocally with a predetermined speed and a predetermined pressing force.

Description

technical field [0001] The present invention relates to a manufacturing method of a double aerosol container, a double aerosol container and a manufacturing device thereof. Specifically, it relates to a method for manufacturing a double aerosol container in which the load on the inner bag is small when the inner bag is inserted into a metal container, a double aerosol container using the manufacturing method, and a double aerosol container used in the method for manufacturing the double aerosol container manufacturing device. Background technique [0002] The currently known double aerosol container is composed of a metal container and an inner bag inserted into the metal container, the inner bag is filled with content, and the gap between the metal container and the inner bag in the metal container is filled with a pressurizing agent. Since the double aerosol container can separate and discharge the contents by a pressurizing agent, various contents can be used for various...
