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.
