CA 2311655
The invention relates to an endpiece for dispensing and/or measuring out liquid pharmaceutical substances, the endpiece comprising a cylindro-conical body (1) fitted with a bottom base (13) for receiving thrust and for coupling to a tank capable of being put under pressure, and an axial ejection duct (10) containing a central core (2) and communicating firstly at its top end with a spray nozzle, and secondly at its bottom end with the tank, it is characterized in that the top end of the ejection duct (10) is closed in temporary and leakproof manner by a wall (111) which is secured to the top portion (la) of said body (1) and which extends perpendicularly to said duct, the wall being movable in reversible manner under drive from the substance, said wall being provided with a central orifice (110) capable of being closed in the closed position by a stud (20) secured to the core (2) being forced thereagainst, the periphery of said wall being attached to said body (1) via an elastically deformable link element (112) enabling said wall (111) to move in axial translation under pressure.
L'invention concerne un embout nasal pour la distribution et/ou le dosage de produits pharmaceutiques liquides comprenant un corps (1) cylindroconique muni d'une embase inférieure (13) d'appui et de raccordement à un réservoir susceptible d'être mis sous pression et d'un conduit d'éjection axial (10) renfermant un noyau central (2) et communiquant, d'une part, à son extrémité supérieure, avec une buse de pulvérisation, et, d'autre part, à son extrémité inférieure, avec le réservoir, caractérisé en ce que l'extrémité supérieure du conduit d'éjection (10) est obturée de manière temporaire et étanche par une paroi (111) qui est solidaire de la partie supérieure (1a) dudit corps (1) et perpendiculaire audit conduit (10) en étant déplaçable de façon réversible sous l'action du produit, ladite paroi (111) étant pourvue d'un orifice central (110) susceptible d'être obturé dans la position de fermeture, par l'appui forcé d'un ergot (20) solidaire du noyau (2), et rattachée audit corps (1) de façon périphérique par un élément de liaison (112) élastiquement déformable permettant, sous pression, la translation axiale de ladite paroi (111).
