To minimize occurrence of a crack at the front end of a glass cylinder even when shocking stress which cannot be predicted normally is applied from outside.
Regarding the syringe 1 used in common as a container, a cylinder tip 3 is fitted to the outer periphery part of the front end of the glass cylinder 2 and a finger clip is fitted to the outer periphery part of the rear end of the cylinder end 2. The inside of the cylinder 2 is filled with a medicament and sealed with a stopper 5a. At the outer periphery of a fitting part 9 of the cylinder tip 3 to the cylinder 2, an annular rib 10 of a diameter larger than that of the fitting part 9 is formed integrally facing a direction orthogonal to the axis of the cylinder 2 as a shock elimination part.
