Universal closure device for bottles

Abstract

A universal closure device for bottles, includes a number of external components, namely coaxial and concentric cylinders, which are connected together to define an external member or enclosure; the external member operating via tongues and a toroidal spring and being used for attachment to the lip of the bottle; and two internal components, namely a suitably conformed cylinder and a piston, operating by two springs. The piston further includes a head which is adapted to mate with a ring connected to the cylinder; the head ( 6 a ) freely sliding along an axial section which is limited by two collars at the top and the bottom. Assembly of the above components allows attachment thereof regardless of the diameter of the neck of the bottle and the height and shape of the bottle lip.
