The remainder reducing 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 remainder reducing member, which is attached to the interior of the flexible inner bag disposed in aerosol container to reduce the final remaining amount of the discharged content, is constituted by a solid rod-shaped body and comprises an attachment portion attached to an inflow port of the inner bag such that said content can flow therein and a guiding portion provided with a plurality of guiding grooves formed in a lengthwise direction of an outer periphery thereof. ## Claims ### Claim at position 1 1-13. (canceled) ### Claim 14 A remainder reducing member that is attached to an interior of a flexible inner bag disposed in an interior of an aerosol container in order to reduce a final remaining amount of content to be discharged, the remainder reducing member being constituted by a solid rod-shaped body and comprising: an attachment portion attached to an inflow port of said inner bag such that said content can flow therein; and a guiding portion provided with a plurality of guiding grooves formed in a lengthwise direction of an outer periphery thereof, wherein a sectional shape of a part formed with said guiding grooves is uniform in said lengthwise direction, and an overlap prevention portion is provided in an intermediate position of said guiding portion in said lengthwise direction, said overlap prevention portion being formed to have a sectional shape different from the shape of the part formed with said guiding grooves. ### Claim 15 (depends on 14) The remainder reducing member according to claim 14, wherein said attachment portion is provided on both ends of said guiding portion. ### Claim 16 (depends on 14) The remainder reducing member according to claim 14, wherein said guiding portion is formed in a columnar shape, and said guiding grooves are provided in said outer periphery at 90° circumferential direction intervals. ### Claim 17 (depends on 16) The remainder reducing member according to claim 16, wherein said guiding grooves are formed with a V-shaped cross-section having a 90° contained angle, and said guiding portion is formed with a cross-shaped cross-section. ### Claim 18 (depends on 14) The remainder reducing member according to claim 14, wherein an end surface of said attachment portion is formed in a smooth convex surface shape. ### Claim 19 (depends on 14) The remainder reducing member according to claim 14, characterized in that end portion grooves are formed between said attachment portion and said guiding portion in a perpendicular direction to said lengthwise direction. ### Claim 20 (depends on 14) The remainder reducing member according to claim 14, wherein at least one discharge groove is formed in a lengthwise direction in an outer periphery of said attachment portion. ### Claim 21 (depends on 20) The remainder reducing member according to claim 20, wherein said attachment portion is formed in a columnar shape, and said discharge grooves are provided in said outer periphery at 180° circumferential direction intervals. ### Claim 22 (depends on 14) The remainder reducing member according to claim 14, wherein intermediate grooves are formed respectively between said overlap prevention portion and said guiding portion on either side thereof in a perpendicular direction to said lengthwise direction, and at least one connecting groove that connects said intermediate grooves on said respective sides and has a predetermined angle relative to said lengthwise direction is formed in an outer periphery of said overlap prevention portion. ### Claim 23 (depends on 22) The remainder reducing member according to claim 22, wherein said overlap prevention portion is formed in a columnar shape, and said connecting grooves are provided in said outer periphery in parallel at 180° circumferential direction intervals. ### Claim 24 (depends on 14) The remainder reducing member according to claim 14, wherein said overlap prevention portion is formed in a cylindrical shape such that a wall portion thereof adjacent to said guiding grooves bulges out toward said guiding grooves. ### Claim 25 (depends on 24) The remainder reducing member according to claim 24, wherein said overlap prevention portion is formed in a cylindrical shape, and a gate for use during injection molding is provided in an interior of said cylindrical overlap prevention portion.
