DESCRIPTION:
BRIEF SUMMARY
The present invention has as its subject an applicator apparatus for a more or less viscous liquid product such as nail varnish.
One already knows apparatus of the hereabove kind comprising a body enclosing a tank provided with a small brush with which is associated a first magnetic element inside of the tank and capable of co-operating with a second magnetic element which is accommodated in sliding relationship in the body outside of the tank.
These apparatus however were generally of a complicated mechanical concept, i.e. comprised a relatively substantial number of parts and therefore were expensive.
Moreover the handling of the prior apparatus notably departs from that of the instruments currently used such as those for the graphic arts.
Therefore, the present invention has as its object to remedy in particular these inconveniences by proposing an applicator apparatus with a very simple structure, not very expensive and the manipulation and the handling of which are very easy and in a way instinctive for the users.
For that purpose the invention has as its subject an applicator apparatus for a more or less viscous liquid product such as nail varnish for example, of the type comprising a body enclosing a tank provided with a small brush or the like with which is associated a first magnetic element inside of the tank and capable of co-operating with a second magnetic element accommodated in sliding relationship in the said body outside of the tank, characterized in that the said tank itself forms a push-button movably mounted axially in the said body against the force of a spring arranged between the said tank and the second magnetic element in order that in the position of the tank pushed into the body, the small brush penetrates into the tank and that in the released position of the tank within the body, the small brush is moved out of the tank.
According to another characteristic of this apparatus, the aforesaid tank is retained in the rest or released position in the body by cooperating shoulders, studs or the like provided in the body and on the tank, respectively.
According to one particular embodiment, the aforesaid tank forming a push-button constitutes a removable cartridge extractable from the body.
In this case, the body comprises an inner shoulder onto which abuts a washer or the like upon which bears, on one side, the aforesaid spring and, on the other side, the aforesaid tank.
One should further specify that in this case here again, one provides a second spring accommodated in the tank, permanently urging the small brush to the position moved out of the tank and the returning force of which is lower than the magnetic returning forces generated by the co-operation of both aforesaid magnetic elements.
Further characteristics and advantages 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 diagrammatically illustrates in axial section an exemplary embodiment of an applicator apparatus according to the invention and shown in the position ready for use;
FIG. 2 is a view similar to FIG. 1, but showing the apparatus in the position of the tank pushed into the body;
FIG. 3 is a view similar to FIG. 1 but showing the apparatus closed by a stopper cap;
FIG. 4 illustrates in axial section another embodiment of an applicator apparatus according to this invention and shown in the position of use;
FIG. 5 is a view in axial section of the portion forming a tank extractable from the body of the apparatus with the elements it contains;
FIG. 6 is a view in axial section of the body of the disassembled apparatus as well as of the stopper cap which may close the body;
FIG. 7 is a view similar to FIG. 4 but showing the apparatus closed by the said stopper cap.
According to the exemplary embodiment shown in FIGS. 1 to 3, an applicator apparatus for nail varnish, for example, according to this invention essentially comprises a small brush 10 carried by a support 11 which is made fast to a first magnet
