Stopper for sealing bottles, particularly for sealing bottles of wine for ageing

摘要

A stopper ( 1, 100, 200 ) for sealing bottles ( 3 ), particularly for sealing bottles of wine for ageing, comprises:-a main body ( 2 ) shaped in such a way as to be removably housed in engagement in an aperture ( 3 a) of the bottles,-a first surface ( 5 ) and a second surface ( 6 ) formed on the main body and facing, respectively, the outside and the inside of the bottles when en the main body is received in engagement in the aperture,-at least one passage ( 4 ) extending between the first and second surfaces and capable of making the inside of said bottles communicate with the environment outside the bottles,-a permeable element ( 16, 101, 201 ) which is impermeable to liquids and permeable to oxygen, the said permeable element being extended to seal the said passage in order to regulate the flow of oxygen between the inside and the outside of the bottle, and having an oxygen permeability, measured at 2O° C., in the range from 10^-5 to 10^-11 (Ncm³*cm/cm²*cm_Hg*s).
