PROBLEM TO BE SOLVED: To provide an ampoule made of resin, the neck part of which will not be broken unintentionally during conveyance, etc., and can easily be broken away by one hand, without trouble such as scattering of its contents due to reaction to this action. SOLUTION: In the ampoule, a thick-walled part 4 is provided between a shoulder part 2 leading to a shell part 1 for storing contents and a neck part 3 thereabove and a notched part 5 formed in the thick-walled part 4 is shaped and sized so that its cutting angleθis 20 deg. to 40 deg. and so that the radius of curvature R of its end is 0.1 to 0.4 mm, with the wall thickness t3 of resin at the position for forming the notched part 6 ranging from 0.6 to 0.75 mm. Thereby, the notching effect of the notched part 5 is ensured. |
