DESCRIPTION:
BRIEF SUMMARY
The present invention has essentially as its subject a container with a brush in particular permitting the application of a more or less viscous liquid product upon any surface such for example as mascara upon the lashes of the eye.
There has already been proposed to provide the neck of a mascara container or bottle with a means for the scraping of the brush, this scraping means permitting the insertion of the brush into the container as well as its dry-squeezing during its withdrawal from the container.
The constriction permitting the scraping was generally constituted by a deformation of the wall of the sleeve which could be freely rotatably mounted into the neck of the container.
However, the rotation of the scraping sleeve within the neck of the container could exhibit problems as well as the insertion of the brush and its withdrawal through the sleeve.
The present invention has as its object to remedy these inconveniences in particular by proposing an improved scraping means which permits a controlled dry-squeezing of the brush in the sense that it could be extracted from the container while being dry-squeezed but while still containing at the end of the bristles a controlled amount of product such as mascara contained in the container.
For that purpose, the invention has as its subject a container with a brush for the application of mascara for example and of the type comprising a scraping means made fast to the neck of the container and constituted by a sleeve the wall of which forms at least one constriction permitting the insertion of the brush into the container as well as its dry-squeezing during its withdrawal from the container, characterized in that the said constriction extends transversely inside of the sleeve so as to define therewith on either side of the constriction, a chamber or the like for the passage of the stem of the brush and another chamber or the like opposite to that cited in the first place and into which are projecting the free ends of the bristles of the brush the length of which is greater than the transverse dimension of the constriction.
According to another characteristic of the invention on either side of the aforesaid construction is provided a concavity communicating with one or the other chamber and in which is accommodated an excrescence of the stem of the brush, which excrescence has in cross-section a shape corresponding to that of the said concavity.
According to another embodiment, one provides in the sleeve two constrictions defining between them and with the said sleeve a chamber or the like for the passage of the stem of the brush and opposite to this chamber, two other chambers into which are projecting the free ends of the bristles of the brush.
One should further specify here that above at least one constriction is provided in the sleeve a snug or the like for the guidance during the insertion of the stem of the brush.
The upper portion of the sleeve preferably exhibits a conicity with a shape corresponding to that of the support of the stem of the brush, which support forms a closure cap for the container.
According to still another characteristic of the invention, the aforesaid constriction is constituted by at least two bosses projecting inside of the sleeve and the mutually confronting portions of which defining the said constriction are either flat substantially parallel surfaces or surfaces with a more complex for example polygonal shape.
The chambers for the passage of the stem of the brush exhibit a shape in cross-section corresponding substantially to that of the said stem and this in such a manner that the rotation of the stem of the brush about its axis be prevented.
But further advantages and characteristics of the invention will appear better in the detailed description which follows and refers to the attached drawings given by way of example only and in which:
FIG. 1 is a view in axial section of a container according to the invention closed by a stopper cap carrying a brush dipping into the product contained in the container;
FIG. 2 is a vi
