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
(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).
