This invention regards the liquid (80) insertion for injecting (40) and bi- Al (30). Bi- Al (30), the liquid (80) the hollow body because it retains (31), the grip part (38) and the head (32) it includes. The head includes, although the axis (X) the supply aperture which is demarcated (33), the supply aperture is closed, adjoining to the head with the closed partition which is suited (34), and projection, one which is demarcated lap direction pushing pressure surface (35) at least. Lap direction pushing pressure surface is concatenated to the grip part shift. Although the insertion with this invention (40), the liquid (80) it supplies, bi- Als axis (X) it receives the interposition which parallels it is suitable. Insertion includes the computer (41) and the inside part (42). The computer includes the side wall (410) and the pipe conduit underneath 1st (511) and the pipe conduit underneath 2nd (521) underneath demarcating, the supply part (411). The inside part includes the inner wall (420) and the punched spike (421). Although the inner wall (420), although bi- Als head is received, the seat section which is suited (422) it demarcates, bi- Al the diameter direction inside part of one lap direction pushing pressure surface (350) engages at least one which is suited slit (423) it includes at least. The punched spike is suitable although bi- Als closed partition is punched, the pipe conduit above 1st (510) and the pipe conduit above 2nd (520) demarcates. As for the inside part, around axis X, in order for it to be possible, to turn vis-a-vis the computer it is stored inside the computer. Especially, the upper part pipe conduit the bottom pipe conduit and the fluid it communicates the inside part, the structure which was opened fluid (A) and the upper part pipe conduit can turn the bottom pipe conduit and the fluid does not communicate the structure which closes fluid (B) in between.本発明は、液体(80)の注入のためのインサート(40)およびバイアル(30)に関する。バイアル(30)は、液体(80)を保存するための中空体(31)、把持部分(38)およびヘッ
