Claims

[Scope of utility model registration request]

The tip of the syringe outer barrel has a wide-mouth bottle-shaped opening, and a hollow rubber stopper with a bottom is tightly fitted into the opening with the bottom facing the inner chamber of the syringe outer barrel. The base portion of the needle attachment tube, which is inserted through the spout hole, is tightly fitted into the part, and the needle attachment tube portion that protrudes outward from the rubber plug is fitted with the base of the injection needle. A cap is fixed to the tip of the syringe outer barrel to seal the outer circumferential area including the needle attachment barrel, and the cap is formed with an easily breakable fragile part, and the cap is fixed to the tip of the syringe outer barrel. A container-cum-syringe in which an inner chamber between a gasket liquid-tightly fitted into the inner chamber of the cylinder and the bottom of the rubber stopper serves as a sealed chamber for filling a drug solution.
