ABSTRACT:

FIELD OF THE INVENTION
1. Background of the Invention
The present invention relates to a univeral stopper for opened bottles. In order to ensure the closure of opened bottles, various types of stoppers have been devised, all of which can be substantially classified in two main groups: stoppers which perform closure of the bottle by causing expansion of one of their components inside the neck of the bottle itself and stoppers which embrace the external surface of the neck of the bottle, making use of its shoulder to ensure a good gripping action.
All these stoppers are provided with means designed to ensure removal of the stopper itself, if possible using a small amount of physical force.
A drawback present in many of the stoppers which are currently commercially available is that they may be difficult to adapt to the various types of necks which may arise.
2. Brief Description of the Invention
The object of the present invention is that of providing a stopper which is extremely versatile and easy to use.
These and other objects are all achieved by the universal stopper for opened bottles according to the present invention, characterized in that it comprises:
an external body which is substantially cylindrical and internally hollow and provided with an upper opening designed to allow rotation of a lever; the bottom part of said external body being provided with a circular opening designed to allow the neck of a bottle to pass through and being provided internally with a circumferential flaring designed to seat a toroidal spring; said spring being able to perform external circumferential locking of the neck of the bottle underneath the associated shoulder;
an internal body, which is substantially cylindrical and designed to slide longitudinally along the internal surface of the said external body, said internal body having its bottom edge in contact with the toroidal spring;
a cylindrical helical compression spring which is positioned between the top part of the internal body and a disk arranged in turn between the said spring and the lever; said spring being designed to convert the rotational movement of this lever into the radial deformation of the toroidal spring in order to compensate for the differences existing both in the diameters of the necks of the various bottles and in the heights of the various shoulders.
