Abstract
The invention concerns an application tip for a device for applying and spreading a liquid, gel or paste product on a given surface configured to allow a volume of product to be transformed and spread over a surface according to a predetermined calibration (C) comprising, internally, a flow control means, —internally, at least one buffer volume, means for controlled dispersion of the product, and a device for applying and spreading a liquid, gel or paste product on a given surface comprising means for storing the product and an application tip according to the invention.
Claims12
An application tip for a device for applying and spreading a liquid, gel or paste type product on a given surface and for allowing a volume of product to be transformed and spread on the surface according to a predetermined calibration comprising
- internally, a means for regulating the flow rate, wherein the means for regulating flow comprises a constriction with a constricted cross section;
- internally, at least one first buffer volume provided between the constriction and the device, wherein the first buffer volume has a first cross section that is larger than the constricted cross section,
- at least one second buffer volume provided on an end of the constriction opposite from the first buffer volume;
- and
- means for controlled dispersion of the product provided on an end of the second buffer volume opposite from the constriction, wherein the means for controlling dispersion comprises a planar face configured to be in contact with the surface, and a recess in the planar face, said recess comprising a least one groove connected to the second buffer volume.
