Definitions

• the present invention relates to an apparatus for applying a more or less viscous liquid product, such as nail varnish for example.
• Apparatuses of the above type comprising a body containing a reservoir provided with a brush with which is associated a first magnetic element inside the reservoir and capable of cooperating with a second magnetic element which is slidably housed in the body outside the tank.
• the present invention aims to remedy these drawbacks in particular by proposing an applicator device with a very simple structure, inexpensive, and whose handling and maneuvering are very easy and in a way instinctive for users.
• the subject of the invention is an apparatus for applying a more or less viscous liquid product, such as nail varnish for example, of the type comprising a body containing a reservoir provided with a brush or the like with which a first magnetic element inside the tank and capable of cooperate with a second magnetic element slidably housed in said body outside the tank, characterized in that said tank itself forms a push button mounted axially movable in said body against the force of a spring arranged between said reservoir and the second magnetic element so that in the pushed position of the reservoir in the body, the brush enters the reservoir, and that in the relaxed position of the reservoir in the body, the brush is in the position removed from the reservoir.
• the aforementioned reservoir is retained in the rest position or released in the body, by shoulders, pins or the like cooperating provided, respectively, in the body and on the reservoir.
• the aforementioned reservoir forming a push button constitutes a removable and extractable cartridge from the body.
• the body has an internal shoulder in which abuts a washer or the like on which the abovementioned spring bears on one side and the abovementioned reservoir on the other side.
• a second spring is provided which is housed in the reservoir, permanently urging the brush in the position from the reservoir, and the return force of which is less than the magnetic return forces generated by the cooperation of the two aforementioned magnetic elements.
• Figure 1 schematically illustrates, and in axial section, an exemplary embodiment of an applicator device according to the invention and shown in the ready-to-use position.
• Figure 2 is a view similar to Figure 1, but shows the apparatus in the pushed position of the reservoir in the body.
• Figure 3 is a view similar to Figure 1 but showing the device closed by a plug.
• FIG. 4 illustrates, in axial section, another embodiment of the applicator apparatus according to this invention, and shown in the position of use.
• Figure 5 is an axial sectional view of the extractable tank portion of the body of the device, with the elements it contains.
• Figure 6 is an axial sectional view of the body of the disassembled device, as well as the plug which can close off the body.
• Figure 7 is a view similar to Figure 4, but showing the device closed by said plug.
• a nail varnish applicator device for example, according to this invention essentially comprises a brush 10 carried by a support 11 which is integral with a first magnetic element 4 and is slidably housed in a reservoir R containing the product to be applied.
• This reservoir R is slidably mounted in a body 12, and is biased by a spring 13 which acts, on one side, on said reservoir, and, on the other side, on a second magnetic element 1 housed slidingly in the body 12, outside the reservoir R.
• the second magnetic element 1 is retained by a flange 20 provided at the end of the body 12.
• the body 12 has an internal shoulder 21 capable of cooperating with an annular shoulder 22 provided on the reservoir R. It would be perfectly possible to use other suitable means other than shoulders, without departing from the scope of the invention.
• the reservoir R forms a push button which, in the rest or released position, will abut by its shoulder 22 on the shoulder 21 of the body 12, and this under the effect of the compression force of the spring 13.
• the brush 10 in the rest position illustrated in FIG. 1, the brush 10 will be in the position taken out of the reservoir R, that is to say ready to use.
• the brush 10 will be retracted in said tank, due to the maintenance of the support 11 of the brush 10 substantially opposite the second magnetic element 1, given the cooperation of the magnetic elements 1 and 4. This means that the brush 10 may be impregnated with the product contained in the reservoir.
• the plug 14 internally comprises a spring 24 connecting the part 23 to the bottom 25 of the plug 14, said part 23 and said bottom 25 being relatively movable by sliding, which, as we understand, allows good sealing of the device, even if the plug 14 is not completely screwed onto the body 12.
• the reservoir R of which advantageously forms a push button itself comprises the following two functions, namely a product filling function, and a device operating function, this operating function advantageously similar to that of the devices usually used for writing, drawing, etc ....
• the reservoir R with the elements that it contains, namely essentially the support 11 of brush 10, forms here a cartridge which can be extracted from the body 12 and be easily replaced by another cartridge.
• a shoulder provided inside the body 12 of the apparatus, and at 27 a washer capable of abutting on this shoulder under the effect of the compression of the spring 13 arranged between said shoulder and the second magnetic element. 1, the spring 13 permanently urging the washer 27 into abutment against the shoulder 26.
• the body 12 consists of a rear part 28 forming a kind of sleeve, and which can be screwed on a front part 29 containing the washer 27, the shoulder 26, the second magnetic element 1, and the spring 13 interposed between washer and magnetic element.
• the reservoir R forming a removable cartridge has an annular shoulder 30 capable of being inserted between the rear part 28 of the body 12 and the washer 27. Also, the shoulder 30 is interposed between the end 28a of the rear part 28 and the washer 27.
• a spring 31 can be provided in the reservoir R and permanently urging the brush 10 in the position extended from the reservoir R, as will be explained later in connection with the operation which will now be explained.
• the spring 31 takes support on one side on the support 11 of the brush 10, and on the other side on a ring or the like 32 internally integral with the reservoir R, this ring 32 also being visible in the mode of embodiment of FIGS. 1 to 3 and serving directly as a stop for the support 11 of the brush 10, when the latter is in the retracted position in the reservoir R.
• the reservoir R visible in FIG. 5 can be extracted from the body 12, to be replaced by another reservoir R, for example containing a different product.
• the applicator device can be closed off with a plug such as 14.
• the spring 31 provides a restoring force which must be less than the magnetic restoring forces generated by the cooperation of the two magnetic elements 1 and 4.
• the presence of the spring 31 eliminates the risk of leakage of the product contained in the reservoir R when the latter constitutes a cartridge located outside the body 12 and capable of taking various positions which may promote leakage.
