Residual quantity reduction member

Abstract

The present invention relates to a residual quantity reduction member with which a space with a circumference closed by a pressurized fluid is prevented from being generated and a final residual quantity of a discharged content is reduced. The residual quantity reduction member of the present invention has a simple structure, is manufactured with ease, easily installed at an inner side of an inner bag, and capable of discharging the content smoothly. The residual quantity reduction member (110), which is installed at the inner side of the flexible inner bag (102) disposed in an aerosol container (100) to reduce the final residual quantity of the discharged content (F), comprises a mounting portion (120) formed of a solid rod-shaped body and installed in such a manner that the content (F) may flow into an inlet (103) of the inner bag (102), and a guiding portion (130) where a plurality of guide grooves (131) are formed in an outer circumferential longitudinal direction.

Description

technical field [0001] The present invention relates to a remaining amount reducing member installed in a flexible inner bag arranged inside a spray container to reduce the final remaining amount of discharged contents. Background technique [0002] There is known an aerosol container configured as follows: a flexible inner bag is integrally arranged inside an outer tank, the inner bag accommodates the contents to be discharged, and a pressurized fluid is filled between the inner bag and the outer tank, and by pressing The flexible inner bag discharges the contents stored in the inner bag from the inlet to the outside (for example, refer to Patent Document 1, etc.). [0003] In such a spray container, since the content does not come into contact with the pressurized fluid, any pressurized fluid can be used, and since the pressurized fluid is not discharged together with the content, the content can be efficiently discharged. [0004] In these aerosol containers, when the re...

AI Technical Summary

Problems solved by technology

[0018] Therefore, in the inner bag of the spray container whose whole is uniformly pressed by the pressurized fluid, there is a problem that the remaining content in the surrounding closed space cannot be guided to the inflow port by the above-mentioned remaining amount reducing member. On the contrary, the protruding part and the hollow part provided in the known margin reduction member become the main cause of the increase of the closed space, resulting in an increase in the residual capacity

[0019] In addition, even if the pressure of the pressurized fluid is increased, the occlusion force of the surrounding closed space is also increased, which is not conducive to the reduction of the remaining amount of the contents.
