Residual quantity-reducing member

Abstract

The present invention provides a residual quantity-reducing member, which: reduces the final residual amount of contents to be discharged by preventing the occurrence of spaces, the perimeter of which is blocked by a pressurized fluid; stabilizes the amount of contents discharged per unit time; and makes it possible to discharge the contents smoothly to the end. Inside a flexible inner bag (102) that is disposed in an aerosol container (100), a residual quantity-reducing member (110) for reducing the final residual amount of contents (F) to be discharged is installed. The residual quantity-reducing member (110) is provided with a mounting part (120) that is mounted on an inflow port (103) of the inner bag (102) so as to allow inflow of the contents F, and a guide part (130) obtained by connecting multiple grooved blocks (132), which have a longitudinal guiding groove (131), in a row in the longitudinal direction.

Description

technical field [0001] The present invention relates to a remaining amount reducing member attached to the inside of a flexible inner bag disposed inside an aerosol container to reduce the final remaining amount of discharged contents. Background technique [0002] There is known an aerosol container which is configured by arranging and integrating a flexible inner bag inside an outer can, storing the contents to be discharged in the inner bag, and filling and pressurizing the space between the inner bag and the outer can. The fluid presses the flexible inner bag, and the contents accommodated in the inner bag are discharged from the inlet to the outside (for example, refer to Patent Document 1, etc.). [0003] In such an aerosol container, since the contents do 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 contents, the contents can be efficiently discharged.

AI Technical Summary

Problems solved by technology

[0026] Even when such a flow path R is tightly pasted with the inner bag, the minimum space is secured and the flow path R is not closed until the end, but the flow path resistance is large, and there is a change in the state of the inner bag during discharge. Furthermore, the flow path resistance may also change significantly.

[0027] In this way, although the contents are smoothly discharged until the end and the remaining amount can be sufficiently reduced, there are various conditions such as the storage state of the flexible inner bag, the material, and the viscosity of the contents, and it is impossible to reduce the contents per unit time. Possibility of stabilizing discharge volume

[0028] And, if Figure 14 As shown in (a), when applied to an aerosol container configured by arranging a plurality of flexible inner bags in one outer tank so as to accommodate different types of contents without mixing them and discharge them simultaneously, each inner bag The discharge amount per unit time of the bag cannot be stabilized, and there is a possibility that the desired mixing ratio cannot be obtained stably
