Abstract

A make up unit comprises a container for mascara, a cap, and a stem carrying a brush which penetrates into the container via a passage axially traversing a wiper element. The wiper element has a wiping zone defining a passage whose cross section is smaller than that of the brush in its state of rest. The wiper element is formed by a lip whose internal edge defines the brush-receiving passage and is joined at its periphery to a ring of a greater thickness, which can sustain, by an axial compression exerted on it, an elastic deformation leading to a variation of the cross-section of the passage. An adjuster ring controls the compression and a reservoir of mascara is accommodated in a barrel. Thus the degree of compression of the wiper element can be adjusted and, as a result, the force of the wiping action will be adjusted.

Dependent claims

In a make up unit for dispensing eyelash make up comprising:

(a) a container for a fluid or pasty make up product, said container having an inlet;
(b) a detachable cap fitted on the container;
(c) a stem coaxial with said cap and having a proximal end integral with said cap, said stem projecting in relation to said cap;
(d) a brush carried by the distal end said stem as an extension of the said stem;
(e) a wiper element having a wiper lip made of an elastic material and disposed at the inlet of said container into which said brush enters, said wiper element including means defining a passage delimited by the inner edge of the wiper lip, said passage having a smaller cross-section than the cross-section of the brush in the undeformed state of the brush;
the improvment wherein said wiper element further includes a ring made of an elastic material joined to the periphery of the wiper lip, said ring having a greater thickness than said lip, and wherein said wiper element is capable of sustaining an elastic deformation leading to a variation of cross-section of the passage under the actuation of control means which varies the axial compression of said elastic ring;
said container being constituted by a movable element and a fixed element between which said ring of the wiper element is interposed, the movable element being capable of axial translation in relation to the fixed element and being connected to the control means;
said container including a neck and a tube formed therewith, the fixed element of the container being constituted by a tube joined to said neck at its end remote from the end cooperating with the control means, said neck and said cap comprising complementary first and second means for fitting the cap on said neck, the connection of said tube to said neck constituting an annular shoulder against which the wiper element bears.
