Patent ID: 8479937

Claim:
A bottle opener, a bottle closure cap and a bottle having a neck, said cap having an upper surface and a lower surface, said bottle opener including a hood comprising an annular skirt adapted to radially surround the cap, and a first hook formed at one axial end of the skirt and including a contact surface with said lower surface, and a transmission lever hinged onto said hood and provided with a gripping section and a working section able to come to bear against said upper surface, wherein: said hood is also provided with two other hooks formed at said axial end of the skirt and which include a contact surface with said lower surface and which are offset in the circumferential direction on both sides of the position diametrically opposite the first hook, by an angle less than 90°; wherein the annular skirt includes slits extending axially from said axial end and delimiting, on said annular skirt, a tab which includes one of said hooks; and wherein the transmission lever is hinged onto said hood so as to swivel about an axis which is aligned radially with said hook of the tab, so that when said transmission lever is swiveled via said gripping section, said working section comes to bear against said upper surface of said cap, and when said transmission lever is further swiveled, the force transmitted at the level of said axis causes a slight rotation of said tab and associated hook.
