A pipe for supplying a liquid filler in a filling region in an inner portion of a container and extruded toward a leading end side, to a brush leading end of the container, comprises ribs in an outer periphery of the pipe portion at uniform interval in peripheral direction. The holder portion, pipe portion, and ribs are formed as injection molded product in which a resin injecting position exists on a surface except the pipe portion and ribs. A pipe for supplying a liquid filler in a filling region in an inner portion of a container (1) and extruded toward a leading end side, to a brush leading end of the container, comprises holder portion (20) attached to the inner portion of the container and is provided with a discharge hole for discharging the liquid filler in the filling region to the leading end side; pipe portion (30) in which a rear end is supported to the holder portion and communicates with the discharge hole, and a leading end is inserted to the brush; and ribs (40) in an outer periphery of the pipe portion at uniform interval in peripheral direction, protrude in a radial direction and reach the holder portion from a middle position in an axial direction of the pipe portion. The holder portion, pipe portion, and ribs are integrally provided and formed as injection molded product in which a resin injecting position exists on a surface except the pipe portion and ribs. An independent claim is also included for a manufacturing method of the pipe, comprising preparing a molding die with a shape corresponding to a shape of the pipe, and has a resin injecting port on a surface corresponding to a portion except the pipe portion and ribs; injecting a molten resin into the forming die through the resin injecting port; and releasing the pipe from the die after being solidified. |
