<P>PROBLEM TO BE SOLVED: To provide a combination container/syringe, capable of removing effectively air bubbles in a chemical liquid. <P>SOLUTION: The combination container/syringe 1 includes: an outer tube 10 having an axis line O as a center; a front stopper inserted into the distal end side of the outer tube 10; and a tube end 50 externally fitted over the outer periphery of the distal end of the outer tube 10 through a fitting hole 61 on the proximal end side, and having a bypass chamber 71 in which a front stopper is transferred on the front side of the fitting hole 61. In the combination container/syringe 1, the inner diameter of the bypass chamber 71 is formed larger than the outer diameter of the front stopper, on the inner peripheral face 73 of the bypass chamber 71, a plurality of ribs projecting toward the inside of the diameter direction, extending in the axis line O direction, and brought into tight contact with the outer peripheral face of the front stopper transferred into the bypass chamber 71, are provided at certain intervals in the peripheral direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
