<p>A plastic cover for a bottle consisting of a cylindrical cap with a belt grip, and having a coaxial cylindrical tube stub directed inside, as well as of a hollow cylindrical plug, characterized in that said cylindrical plug (2) is connected to said cylindrical tube stub (3) of said cap (1) by means of a means to be broken, advantageously in a shape of a shape of a circular connecting film (4). A method consists in that said cylindrical plug 2 having a circular flange (7) together with said cylindrical cap (1) are injection formed in an injection mould, wherein after injection a motion of a forming male die (12) is caused in relation to a forming plate (16) to release an outer cylindrical surface of said cap (1), and at the same time an ejector (17) supporting the bottom (8) of the cylindrical plug (2) is slid so as to achieve a simultaneous cylindrical cap (1) and the plug (2) connected one to another by means of the connecting film (4) from the injection mould, and then the closure is blown with compressed air in order to reliably eject it from said injection mould.</p> |
