- 摘要：
PROBLEM TO BE SOLVED: To provide a syringe-shaped container for storing a viscous paste, capable of preventing air mixed when the paste is stored from being mixed in the paste to be discharged when the container is used.
SOLUTION: The syringe-shaped container is composed of a cylindrical cylinder which has an tapered discharge part at one end and an opening with a finger hook part on the outer surface at the other end and in which the paste is stored a plunger 2 having a head part 2a in such a shape as approximately adapted to the discharge part of the cylinder, and an O-ring attached groove 2b, a rod part 2c and a presser part 2d disposed in the order following the head part 2a for extruding the paste inside the cylinder toward the discharge part 1a side and an O-ring attached to the O-ring attached groove 2b of the plunger 2. In the syringe-shaped container, a channel through which air permeates but the paste does not permeate from the head part 2a to the rod part 2c side is formed in the O-ring attached groove 2b of the plunger, and preferably, a plurality of grooves or projecting lines 2e are formed between the plunger 2 and the O-ring 3 parallel to the axis of the plunger 2.
