Title
(EN) SQUEEZE BOTTLE FOR DISPENSING A LIQUID IN A METERED AND SUBSTANTIALLY GERM-FREE MANNER
(FR) FLACON PRESSABLE POUR UNE DISTRIBUTION DE LIQUIDE PAR DOSES ET SENSIBLEMENT DEPOURVUE DE GERMES
Abstract
(EN)
The invention describes a squeeze bottle (1) for dispensing a liquid, in particular a liquid medicament, in a metered and substantially germ-free manner, at least comprising: a storage chamber (2) for accommodating the liquid, a metering chamber (3) with a variable volume for dispensing from this chamber, under reduction of volume of the chamber, a measured volume of liquid, restoring means (8) for returning the metering chamber to its original state after a volume of liquid has been dispensed, an inlet (4) for placing the metering chamber in communication with the storage chamber by mediation of a flow restrictor, which flow restrictor counteracts flow from the metering chamber to the storage chamber substantially completely, when the pressure in the storage chamber is increased, counteracts flow between the storage chamber and the metering chamber substantially completely and, when the increased pressure in the storage chamber is removed, allows flow from the storage chamber into the metering chamber, at least one outflow opening (5) for placing the interior of the metering chamber in communication with the environment, the outflow opening comprising a non-return valve (6), actuating means (7) for reducing the volume of the metering chamber, which actuating means can be actuated by squeezing the bottle, means for ventilating the squeeze bottle.
(FR)
L'invention concerne un flacon pressable (1) permettant d'obtenir une distribution de liquide, notamment un médicament, par doses et sensiblement dépourvue de germes. Ce flacon comprend au moins : un chambre de stockage (2) destinée à contenir le liquide ; une chambre de dosage (3) à volume variable destinée à distribuer, lorsque son volume est réduit, une dose de liquide ; un dispositif de rétablissement (8) destiné à ramener la chambre de dosage à son volume original, une fois la dose distribuée ; un orifice d'entrée (4) destiné à mettre la chambre de dosage en communication avec la chambre de stockage au moyen d'un limiteur de débit, lequel neutralise presque complètement le courant allant de la chambre de dosage à la chambre de stockage, lorsque la pression à l'intérieur de la chambre de stockage est augmentée, neutralise presque complètement le courant allant de la chambre de stockage à la chambre de dosage et, lorsque la pression à l'intérieur de la chambre de stockage est supprimée, laisse passer le courant de la chambre de stockage à la chambre de dosage ; au moins une ouverture de sortie du courant (5) destinée à mettre l'intérieur de la chambre de dosage en communication avec l'environnement et comprenant un clapet de non-retour (6) ; un dispositif d'activation (7) destiné à réduire le volume de la chambre de dosage et pouvant être activé par compression de le flacon ; enfin, un dispositif destiné à aérer le flacon.
