A SELF-OPENER CLOSURE FOR COMPOSITE PACKAGINGS OR FOR CONTAINER SPOUTS OR BOTTLE SPOUTS TO BE CLOSED WITH FILM MATERIAL

摘要

The self-opening closure comprises a pouring nozzle (2) which may be mountedon a composite packaging or a container or bottle nozzle for sealing oralready sealed with film material, a corresponding twist cap (1) and a self-opener sleeve (3), arranged within the pouring nozzle (2) which may be made torotate by the twist cap (1). Force transfer means and guide means are mouldedon said three elements, which cooperate such that on first rotating the twistcap (1) in the opening direction, the self-opening sleeve (3) is verticallypushed downwards in the pouring nozzle (2) and then rotated in the horizontaldirection through about 360~. As the self-opening sleeve (3) is provided onthe lower edge thereof with a combined piercing and cutting body (9) whichprotrudes therefrom, the film or the packaging is firstly reliably puncturedand then a disc is cleanly cut from the same and then folded downwards.
