Abstract: A cap for plugging a bottle comprising two lids and a roll so as to be able to be forcibly inserted into the neck of the bottle, characterised in that it comprises: a semi-finished cap with a reduced diameter (10) formed by a cap made of crushed cork glued under pressure with a polyurethane binder, having a diameter uniformly reduced by a thickness equal to twice a predetermined thickness the semi-finished cap with a reduced diameter (10) comprising two end faces (10a) and a lateral face (10b), a cork sheet (20a, 20b) glued on each of the end faces and on the lateral face of the semi-finished cap with a reduced diameter (10).

Abstract: A method for manufacturing a cap for plugging a bottle so as to be able to be forcibly inserted into the neck of the bottle, comprising the following steps: cutting cork sheets to be glued on the lids and on the roll of the cap, gluing one of said cork sheets on the roll of the semi-finished cap with a reduced diameter by depositing a binder suitable for food contact, followed by baking, and gluing each of the other cork sheets on each lid of the semi-finished cap with a reduced diameter by depositing a binder suitable for food contact, followed by baking, the semi-finished cap with a reduced diameter being a cap made of crushed cork glued under pressure with a polyurethane binder, having a diameter uniformly reduced by a thickness equal to twice the thickness of a cork sheet glued on the roll.

Abstract: Stopper intended for bottling still wines, characterized in that it includes cork strips laterally joined by a polyurethane binder so as to form a plurality of cork strips, the cork strips being disposed such that the thickness thereof is perpendicular to the axis of the stopper, at least one lateral cork strip joined by a polyurethane binder to each face of the plurality of cork strips revealing all cork strips, the lenticels possibly present in the cork strips extending parallel to the thickness of the strips while those in the lateral cork strips extend perpendicular to the thickness of the strips, such that all lenticels of the stopper are disposed perpendicular to the axis of the stopper in order to limit the variation in oxygen permeability from one stopper to the other.
