Abstract (en)
[origin: JPH0271743A] PURPOSE: To discharge all amount of the content quickly with small amount of rinsing by providing a membrane at the lower end of a sleeve. CONSTITUTION: A funnel shaped sleeve 3 has a membrane 4 supported by webs of at least 2 or preferably 3 at the neck of the lower end of the funnel shape, and the sleeve 3 is welded to an ampule 2. The body 2 of the ampule and the sleeve 3 are connected by a screw 6. By turning the ampule body 2, the membrane cracks open and a round shaped opening 8 comes out. By continuing to turn the ampule body 2, as the material of the membrane is being removed, free flow of the liquid contained in the ampule is not obstructed.
