Abstract
Applicator including a reservoir containing a substance to be applied, a cap intended to close the reservoir and supporting a stopper including an applicator holder supporting a deformable element for applying the substance. The deformable element has a shape memory, i.e., can return to its original shape after being deformed, and a roughened surface. The reservoir holding the substance includes an end-piece having a base equipped with a seat including at least one capillary orifice against which the deformable element deforms when the reservoir is closed by the cap.
Claims15
Applicator, comprising:
- a reservoir for containing a substance to be applied;
- a cap engageable with the reservoir for closing the reservoir;
- and
- an applicator holder supporting a deformable element for applying the substance, said deformable element being movable between a first configuration when the cap is disengaged from the reservoir, and a second configuration deformed relative to the first configuration, when the cap is engaged with and closes the reservoir,
- wherein the deformable element has a roughened surface, and
- wherein the reservoir includes an end-piece having a base equipped with a seat including a capillary orifice against which the deformable element is applied, assumes the second deformed configuration when the reservoir is closed by the cap, and collects through capillary action the substance.
