Abstract

L'invention porte sur un bouchon (10) de récipient comprimable se montant sur le col (12a) du corps (12) du récipient de plastique, déformable lorsqu'on en comprime le fût (12b) pour en expulser le contenu liquide par une ouverture (13) située au sommet du bouchon (10). Une partie au moins du conduit transférant le liquide du col (12a) à l'ouverture (13) est hélicoïdale (15). La partie (15a) de la surface inférieure du conduit hélicoïdal (15) est conçue pour s'abaisser vers le fût (12b) du récipient lorsque ce dernier est vertical. Le conduit (15) peut par exemple consister en un tube hélicoïdal (14) placé à l'intérieur du bouchon (10).
