Title
(EN) CONTAINER FOR PACKAGING A LIQUID TO BE DISPENSED IN DROPS REVERSIBLY DEFORMED BY AIR INPUT
(FR) RECIPIENT POUR LE CONDITIONNEMENT D’UN LIQUIDE A DISTRIBUER GOUTTE A GOUTTE, A DEFORMATION REVERSIBLE PAR ADMISSION D’AIR
Abstract
(EN)
The invention concerns a container for packaging a liquid (1) to be dispensed in drops, said container being reversibly deformed by air input and being equipped with a head (3) for dispensing liquid through a nozzle (5). The latter (3) comprises a recessed body (4) which is nested inside a neck (10) of the container and which holds a hydrophobic microporous pad (8) arranged upstream of a chamber (9). Said chamber (9) is provided with an air reservoir for preventing the liquid from passing through the microporous pad between two liquid dispensing operations when the nozzle (5) is sealingly obstructed with a cap (6) and for drying a partly hydrophilic and hydrophobic filtering membrane (7) arranged in the dispensing head (3).
(FR)
L’invention a pour objet un récipient pour le conditionnement d’un liquide (1) à distribuer goutte à goutte, ce récipient étant à déformation réversible par admission d’air et étant équipé d’une tête (3) de distribution du liquide à travers une buse (5). Cette dernière (3) comporte un corps évidé (4) qui est emboîté à l’intérieur d’un col (10) du récipient et qui loge un tampon microporeux hydrophobe (8) disposé en amont d’une chambre (9). Cette chambre (9) ménage une réserve d’air pour, entre deux opérations de distribution de liquide, empêcher le liquide de traverser le tampon microporeux lorsque la buse (5) est obstruée de façon étanche par un capuchon (6) et assécher une membrane filtrante partiellement hydrophile et hydrophobe (7) que comporte la tête de distribution (3).
