Abstract
An amplule for a liquid, removed from the ampule by a hypodermic syringe, has a neck. A conical member on one end of the hypodermic syrings is introduced into the neck of the ampule. The inside wall of the neck of the ampule is of a configuration which allows for the passage of air, but does not allow the passage of liquid in the area intended for the installation of the conical member. The shaped configuration between the socket member wall and the inside wall of the neck of the ampule is in the form of a circular closed line.
