PROBLEM TO BE SOLVED: To prevent a burr, produced from the joint portion by welding between a liquid formulation container and an injection unit, from interfering with a boring member inserted into a jig communication passage when the boring member is inserted into the jig communication passage to prevent the obstruction of the piercing action through a sealing member by the edge of the boring member. SOLUTION: In a sealing pump-up device 10, a tubular inner annular member 104 is integrally formed on the inner peripheral side of a joined portion 37 in an injection unit 20 so as to surrounded, from the outer peripheral side, a boring member 62 held in a jig insertion hole 44, and a burr housing unit 106 consisting of a substantially cylindrical space is formed between the outer annular member 28 of a liquid formulation container 18 and the inner annular member 104, whereby it is possible to guide the tip end side of a burr 110 upward by the inner annular member 104 while preventing the burr 110, extending from the joint portion between the outer annular member 28 and the joint portion 37 toward the inner peripheral side, from moving toward the boring member 62 side of the burr 110 by means of the inner annular member 104.
