Abstract

A process for making a closure cap (2) provided with a gasket (5) from a polypropylene material for a container (1), said closure cap (2) comprising an end wall and a circumferential side wall (11), in which process the gasket (5) is formed in the closure cap via a melting and a cooling operation by applying in the closure cap an amount of plastisol which is shaped therein into a gasket configuration at an elevated temperature adjusted after the plastisol addition causing the plastisol shaped into the gasket configuration to melt completely by further energy supply and then cooling same to form the gasket, whereby starting from an integral combination of the closure cap (2) with a sealing ring (13) which is connected with the closure cap by means of a number of frangible bridges (12) capable of being broken on the first opening of the container, and, to form the gasket (5), carrying out the melting operation by heating the closure cap after addition of the plastisol to a temperature of 50 to 110 DEG C and by exposing the resulting plastisol shaped into the gasket configuration subsequently, as is known per se, to microwave energy until the plastisol has been completely molten.
