DESCRIPTION:
BRIEF SUMMARY
The subject of the invention is essentially an improved brush for application of a liquid, paste, or powdery product of any kind whatsoever, for example, mascara.
Various structures have already been proposed for brushes for applying mascara, which generally comprise a shaft in the form of a tube that is slit along at least one generatrix and that is connected to a handle that forms the product reservoir, wherein said tube contains an insert in the form of a split cylinder whose free edges project from the slit in the tube.
Applied around the insert are flexible filaments whose free ends project from the slit in the tube between said slit and the free edges of the insert to thereby constitute the bristles of the brush.
However, it has been shown that manufacturing problems may arise with such a brush structure, wherein the assembly of the various constituent elements remains tricky.
In addition, the aim of the invention is specifically to remedy this type of problem by proposing an improved brush structure comprising a minimum number of components, one that is less expensive and permits particularly efficient application of any type of product, for example, mascara, to be applied to the eyelashes.
To that end, the object of the invention is a brush for application of a liquid, paste, or powdery product such as mascara in particular, and of the type that comprises a shaft in the form of a tube that is slit along at least one generatrix and is connected to a handle forming the reservoir, and in which tube is housed an insert in the shape of a split cylinder whose free edges project from the slit in the tube, characterized by the fact that at least one of the opposing free edges of the split cylinder contains teeth or the like made of the same material as it is and forming a comb that is capable of permitting application of the product.
It is already clear that the brush according to the invention is particularly easy to manufacture by virtue of the fact that it is limited to essentially two parts: the split tube and the toothed insert housed in the tube.
According to another embodiment, each of the two free edges of the split cylinder projecting from the slit in the tube has teeth so as thereby to form a double comb.
The brush according to the invention is further characterized by the fact that the gap between the opposing free edges of the split cylinder projecting from the slit in the tube is sealed at the end of such edges by plates or the like, while the end of the split tube receiving the insert is sealed by a plug or the like.
According to another embodiment, the end of the split tube receiving the insert is sealed by a plug or the like with an ear that seals the gap between the opposing free edges of the split cylinder on one side of the cylinder, while on the other side of the cylinder said gap is sealed by a plate or the like.
But other characteristics and advantages of the invention will become clearer in the detailed description that follows with reference to the attached drawings given by way of example only, where:
FIG. 1 is a perspective view of part of the shaft of the brush according to the invention, the end of which is not sealed with a plug, for greater clarity.
FIG. 2 is a view similar to the above except that it shows a variant of the brush, namely a brush forming a double comb, while the brush illustrated in FIG. 1 is a brush with a single comb.
FIG. 3 is a schematized perspective view of a plug with an ear that seals the brush shaft end.
With reference specifically to FIGS. 1 and 2, one sees a brush that is made up essentially of shaft 1 in the form of a tube split along at least one generatrix, the slit in the tube being formed at 2.
Split shaft or tube 1, of which open end 3 is visible, is connected at its opposite end to a handle (not shown) forming a reservoir for any type of liquid, paste, or powdery product to be applied.
Housed in tube 1, as clearly shown in the figures, is insert 4 in the form of a split cylinder whose free edges 4a, 4b project from tube 1 through slit 2 cut in
