Abstract
A device for applying a liquid, paste or gel product to the skin, with a reservoir for the product, an abutment connected by at least one feed channel to the reservoir, and an applicator element that is provided with a plurality of passages for the product and whose outside surface forms an applicator surface. The applicator element is held flexibly and/or movably with respect to the abutment so that it can assume at least one working position in which it, together with the abutment, borders a space to accommodate a predetermined quantity of the product, and where the space is reduced in size under deformation of the applicator element and/or movement of the applicator element with respect to the abutment.
Claims13
A device for applying a product comprising:
- a first reservoir containing the product;
- an abutment having at least one feed passage having an inlet and an outlet for receiving product from the first reservoir through the inlet and delivering product to the outlet;
- a second variable volume reservoir defined between the abutment and a moveable applicator element for receiving product from the outlet of the at least one feed passage of the abutment such that the product moves the applicator element and increases the volume of the second reservoir for receiving the product, the movable applicator having a plurality of selectively opened valved passages for transferring product from the second reservoir to an application surface of the movable applicator when opened wherein the valved passages are selectively opened in response to (1) delivering of excess product from the first reservoir through the at least one feed passage to the second reservoir and (2) pressure asserted on the application surface of the movable applicator element.
