Abstract (en)
[origin: JPS6423960A] PURPOSE: To make thrusting of a projection into a foil or membrane easily detectable by forming a truncated conical projection. CONSTITUTION: A push-button projection is truncated-conical, where an inclined wall 18 is thinner than a flat wall 7, but the thickness of the upper wall is equal to that of the flat wall 7. Pushing a projection 16 downward folds the inclined wall 18 and prevents a thick section 20 of the inclined wall from being depressed lower underneath the level of the upper wall 7. A tip 21 is located near pour opening 8. A foil F is broken by the tip 21, and a broken section F' is rolled along a sloped cut face 22. The content of the container flows toward the pour opening 8 through between the foil F and the flat wall 7.
