DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a device for the obturation of an apparatus for the application of a viscous liquid product, such for example as nail varnish.
It is also directed to an applicator apparatus usable with this device.
In the prior art, applicator apparatus are known which are provided with an applicator brush in contact with a product contained in a tank, and which in a general manner are obturatable by a stopper the mounting of which on the body of the apparatus and the removal of which are controlling the putting out of service, i.e., closing, or in retracted position of the applicator brush and its putting into service, i.e., opening, or in position of egress and of use, respectively.
Such prior art devices are, for example, described in the documents DE-A-2,944,336 and DE-A-3,635,690.
In these references, however, the stopper directly actuates the applicator brush upon the closing or the opening of the container to carry out its retraction or its putting into service, respectively. It results therefrom that the mounting and the removal of the stopper may in the course of time deteriorate the brush or at least alter its qualities of fineness.
OBJECTS AND SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to remedy in particular the hereabove inconveniences by proposing an obturation device which does not risk damage to the applicator brush upon the closing and the opening of the container and which in addition permits a reliable and positive obturation which opposes the accidental flowing out of the liquid contained in the tank and remaining in contact with the applicator brush.
For that purpose, the invention has as its subject a device for the obturation of an apparatus for the application of any more or less viscous liquid product, which is fitted with an applicator brush in contact with the product contained in a tank and which may be obturated by a stopper the mounting of which on the body of the apparatus and the removal of which are controlling the putting out of service or in a retracted position of the applicator brush and the putting into service or in position of egress and of use, respectively, of this applicator brush. In the device, the stopper, upon the obturation of the body, actuates a sleeve or the like movably mounted in the body so as to provide the retraction into this sleeve of the applicator brush accommodated inside of the sleeve and fixedly mounted within the body. Upon the opening of the body, the stopper actuates the sleeve in the reverse direction to disengage the applicator brush from the sleeve and to thus permit its use after separation of the stopper from the body of the apparatus.
One thus understands already that the stopper does not risk damage to the applicator brush since it will act only upon the movable sleeve permitting the sleeve to completely cover the brush or to put it in position of use or in a position of being moved out of the sleeve.
According to another characteristic of this device, the stopper comprises a portion co-operating by screwing with the movable sleeve and a portion co-operating by abutment with the body of the container to perform, upon screwing, the retraction into the sleeve of the applicator brush which thus remains in close contact with the liquid product contained in the tank.
Otherwise, the screwing of the stopper will cause the attraction of the sleeve and the retraction of the applicator brush fixedly mounted within the container.
According to still another characteristic of the invention, the stopper is provided internally with a spring with which is associated a ring through which may extend the brush and cooperating with an aperture forming a seat in the sleeve as from the beginning of the mounting and of the screwing of the stopper onto the sleeve.
The invention is also directed to an applicator apparatus usable with an obturation device meeting either one of the hereabove characteristics and characterized in that the sleeve is, on the one hand, mounted in flui
