A lid (1) for a drinks container has a mouthpiece (6) provided with a valve (2) which comprises a membrane (7) of resiliently flexible material formed generally at its centre with at least one slit or other piercing (8) which is normally sealed. The membrane (7) is dished inwardly of the mouthpiece, but when suction is applied, it is caused to invert to allow liquid to be drawn through its slit(s) (8). The valve (2) may instead be provided in the top of a drinks carton or in the end of a drinking straw.

Ce couvercle comprend un embout (6) muni d'un clapet (2) comprenant une membrane (7) faite en matière souple résiliente, comportant, d'une manière générale, en son centre au moins une fente ou un autre type d'ouverture (8), normalement étanche. La membrane (7) est incurvée vers l'intérieur de l'embout, mais lors de l'application d'une aspiration, elle se retourne pour laisser le liquide passer à travers la ou les fentes (8). Le clapet (2) peut être placé également sur le dessus d'un carton à boissons ou à l'extrémité d'une paille à boissons.
