Abstract
The invention relates to an application device for a liquid product, contained in a reservoir bottle. The device comprises a lid, closing the opening of the bottle, through which at least one capillary migration channel for the liquid product 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. The other end opens in a collector tube for the liquid product, contained in the bottle. The collector tube is embodied to hold a fixed amount of liquid product against gravity by means of capillary action, until the above is drawn off by capillary migration through the lid channels.
Claims13
An applicator device for a liquid product contained in a reservoir bottle, said device comprising a lid for closing the opening of said bottle, at least one migration canal through said lid for the capillary migration of said liquid product to a wetable surface brought into contact therewith outside said bottle, a downstream end of said capillary migration canal opening to the outside of said lid, and a withdrawal tube for withdrawing said liquid product from said bottle, in which an upstream end of said migration canal opens and that is constructed so as to retain a determined dose of liquid product withdrawn from said bottle against the action of gravity through a capillary effect.
