PURPOSE:To attain compactness of a vessel for infusion, simplify the preservation and to make it easy to mass transportation by fitting a capsule whose lower end is closed by a closing film and being embedded in a mobile vessel and piercing the closed film at the lower end of the capsule after piercing the cork of the liquid medicine vessel. CONSTITUTION:The upper end of a capsule 2 housing the vial is opened. A bottom part 23 and a housing part 16 projected downwards from the bottom part 23 and whose lower end is closed by a closing film 38 housing the lower end of a piercing needle 7 are integrally formed on a lower end part 15. When the cap is rotated, a cam pushes down the pressing member and the vial falls. The port part bends the pressure part of the control means 6 and the control means 6 does not fall. When the vial falls and the port part is put between the pressure part of the control means 6 and the rubber cork is pierced by the upper blade of the piercing needle 7. Further, when the cap is turned more, the control means 6 falls and the lower blade of the piercing needle penetrates the closing film 38 of the capsule 2. |
