The invention relates to an application device (3) for a liquid product (2), contained in a reservoir bottle (1). The device (3) comprises a lid (7), closing the opening of the bottle (1), through which at least one capillary migration channel (5) for the liquid product (2) passes towards a wettable surface on contact therewith. Several similar capillary channels are preferably provided, which can alternatively function as openings for the entry of air through the lid. One of the ends of each channel opens outside the lid (7). The other end opens in a collector tube (6) for the liquid product (2), contained in the bottle (1). The collector tube (6) is embodied to hold a fixed amount of liquid product (2) against gravity by means of capillary action, until the above is drawn off by capillary migration through the lid channels.

L'invention concerne un dispositif applicateur (3) pour un produit liquide (2) contenu dans un flacon réservoir (1). Le dispositif (3) comporte un couvercle (7) fermant l'ouverture du flacon (1), qui est traversé par au moins un canal (5) de migration capillaire du produit liquide (2) vers une surface mouillable amenée à son contact. On prévoit de préférence plusieurs canaux capillaires similaires, capables de servir alternativement en orifices de rentrée d'air à travers le couvercle. L'une des extrémités de chaque canal débouche à l'extérieur du couvercle (7). L'autre extrémité débouche dans un tube de prélèvement (6) du produit liquide (2) contenu dans le flacon (1). Le tube de prélèvement (6) est réalisé de manière à retenir une dose déterminée de produit liquide (2) contre la gravité par phénomène de capillarité, jusqu'à ce qu'il soit progressivement aspiré par migration capillaire à travers les canaux du couvercle.
