But if it were so easy / to replace the crown corks with plastic bottle stoppers; then a crown cap would no longer be used at present. The basic type of execution, in which one tries to build up plastic bottle closures, "consists of a hat shape, a plug part to be pressed into the bottle opening and a sleeve-like dumbbell il _p that encompasses the bead of the bottle opening on the outside like a snap-lock, both of which are connected to one another by a headband With the stopper part one tries to do the main sealing work in the bottle opening, while with the dumbbell part not only a snap-lock-like holder on the edge bead of the bottle opening should take place, but also an additional seal «,
