Patent AT-E400419-T1: [Translated] MAKING A BOTTLE WITH A PUSH CAP

A method of manufacture of a bottle which may be closed by a push-on closure, apparatus for manufacturing the same, a bottle and a closure for the bottle. A bottle is manufactured in a multi-component assembly. The bottle preform (not shown) is made by an injection molding technique, having detents on its upwardly and outwardly facing surfaces. It is then transferred to a blow mould where it is first heated, and then shaped by inserting a blow pin through the neck of the preform to stretch it in its longitudinal axis. During this operation, the top surface of the preform is bent down, such that the detent formed on the upwardly facing surface of the preform now extends laterally into the volume of the preform. The stretched preform is then blown to take the shape of the blow mould, forming the bottle. A closure is formed by injection moulding, and is held on the bottle by the laterally extending detents.
