Field of the Invention The present invention relates to a double-structured container in which an inner container is placed in an outer container, and more particularly, to a double-structured container in which the shape of the inner container is made easier to insert into the outer container and to make it easier to manufacture. It relates to a heavy structure container.

Liquefied gas, compressed gas, etc., which are connected to each other, and further contain the contents to be discharged in the inner container d, and serve as a pressure source for injecting the contents into the outer container b between the inner container d and the outer container b. The basic configuration is to enclose a propellant.

And the like adapted to the body diameter of the body are used. Thus, the inner container d has a spur gear-shaped wall f in cross section, so that the inner container d can be easily narrowed and can be easily inserted into the outer container b. When the content to be jetted is press-fitted into the container d, the spur gear-shaped wall f expands to increase the internal volume, and the content is increased accordingly. In the case of the inner container adapted to the body diameter of the outer container b, the volume of the inner container was reduced by using a decompression device or the like, and then the inner container was placed in the outer container b.

In the direction, for example, from the direction of arrow A in FIG. 9, the protrusion at the position of g hinders the mold from being easily released, and a four-part mold is used or a forced mold is released. The cost of the mold becomes expensive, or the difficulty of the mold release becomes a problem. Moreover, in the inner container matched to the body diameter of the outer container b,
As described above, after squeezing using a decompression device or the like, it is necessary to put the inside of the external container b, and there is a problem that operability is extremely poor.

The sealing material 11 is bent downward, the small hole 12c of the stem 12 is opened, and the injection port 14 and the passage 1 of the stem 12 are opened.
Since the atmospheric pressure is reached through the inner container 4 via 2b or the like, the inner container 4 is pressed by the pressure of the propellant in the outer container 2, and the contents in the inner container 4 are discharged to the outside. Will be. When the external force applied to the injection port 14 is released, the stem 12 returns by the spring force of the resilient spring 13 to close the small hole 12c with the sealing material 11, and the discharge of the contents stops.

After blow molding the inner container, the inner container can be easily inserted into the outer container by releasing the mold from the mold in one direction and narrowing the bellows wall surface. After the inner container is inserted into the outer container, the bellows wall surface expands according to the filling pressure of the contents.
The filling rate of the contents to be stored in the inner container can be kept high. Therefore, regardless of whether the filling rate of the inner container is the same as or higher than that of the conventional one, it becomes extremely easy to manufacture the inner container itself and insert it into the outer container. Further, if the inner container is formed symmetrically with respect to the parting line, the above-mentioned effect becomes more remarkable, and in addition, there is a feature that a mold can be easily made.
