A valve member for a recording liquid supply port connectable with a liquid ejection recording means for supplying recording liquid to said liquid ejecting means, comprises an elastically deformable plate-like member; a plug member on one side of said plate-like member; a supporting member for supporting said plate-like portion on said liquid container, said supporting member being on said one side thereof; wherein said plug member has A sealing portion, adjacent a free end portion thereof, for substantially plugging said liquid supply port by being inserted into the liquid supply port, and a liquid feeding portion, away from the free end portion, said liquid feeding portion having a cross-sectional area which is smaller than that of said sealing portion, wherein the cross-sectional area is in a plane parallel with the liquid supply port.

La présente invention porte sur un clapet monté sur un orifice d'évacuation du liquide enregistreur et pouvant être raccordé à un dispositif d'éjection du liquide enregistreur en vue d'alimenter ce dispositif d'éjection en liquide enregistreur. L'objet de l'invention comprend en outre un élément résilient semblable à une plaque; un bouchon d'un côté dudit élément semblable à une plaque; et une pièce de support maintenant l'élément semblable à une plaque sur ce contenant de liquide, d'un côté de cette pièce de support. Le bouchon est doté d'une étanchéité adjacente à une extrémité ouverte, en vue d'obturer en grande partie l'orifice d'évacuation du liquide enregistreur lorsqu'il est inséré dans cet orifice, et d'une zone d'alimentation en liquide, située à une certaine distance de l'extrémité ouverte, et dont la section transversale parallèle à l'orifice d'évacuation en liquide enregistreur est moindre que celle de ladite étanchéité.
