Definitions

• the present invention relates to a fluid application device for applying a fluid product to a target surface using an applicator.
• the transfer of fluid product from the applicator which is an integral part of the fluid dispenser, is effected by contact of the applicator with the target surface, which may for example be the skin of a user of the dispenser.
• the fluid product may be of low viscosity, such as perfume, but preferably it will be here a fluid more viscous, such as oil or serum.
• document FR2924696 describes a fluid applicator device comprising an applicator defining a piston lip which slides in a sealed manner in a sampling chamber connected to a fluid reservoir by a dip tube.
• a vacuum is generated inside the chamber, which causes the fluid product of the reservoir to rise through the dip tube.
• the applicator defines a blind space whose opening is defined by the piston lip.
• a pipe which extends in the extension of the dip tube protrudes inside the blind space when the applicator is in place on the tank.
• the user can apply the fluid product on his skin by contacting the piston lip with the skin. It should be noted that the tubing projecting inside the blind space of the applicator does not come into contact with the applicator, of which only its piston lip comes into contact with the chamber.
• document FR2978742 is also known, which describes a fluid applicator device having an architecture similar to that of document FR2924696.
• the major difference with the previous document is that the fluid product is injected inside the blind space in the form of an axial jet through an injection port which is permanently located outside the blind space of the applicator.
• the piston that creates the vacuum in the room is located outside the blind space.
• the fluid applicator devices of the two aforementioned prior art documents are designed for fluid products of low viscosity, such as perfumes. Because of their architecture, they are not able to handle more viscous fluid products, such as oils or serums.
• the present invention aims to define a fluid application device that allows use with viscous fluids, without excluding other fluid products less viscous, such as perfumes. Therefore, an object of the present invention is to define a more universal fluid product application device that can handle all types of fluid products from more viscous to less viscous.
• the present invention proposes a device for applying a fluid product, comprising:
• this fixed mounting piece intended to be fixed on a reservoir containing fluid, this fixed mounting piece comprising a dip tube intended to extend into the reservoir,
• this fluid product applicator removably mounted on the fixed mounting part, this fluid product applicator comprising a sleeve internally defining a sampling chamber adapted to take fluid drawn in through the plunger tube,
• the sleeve comprises a cylindrical inner wall and the fixed mounting piece comprises a pipe which extends in the extension of the dip tube and which forms a piston lip adapted to come into sealing contact with the cylindrical inner wall of the sleeve.
• the swaging takes place inside the sampling chamber, and not outside. In this way, it is ensured that the fluid drawn through the dip tube and the tubing is deposited in the sampling chamber starting from its bottom. When the fluid product is viscous, it is not injected into the sampling chamber, but rather deposited gradually as the tubing is extracted from the sleeve.
• the sampling chamber comprises a mouth and a bottom, the tubing extending in the sampling chamber with the piston lip located closer to the bottom than the mouth, when the applicator of fluid product is mounted on the fixed mounting part.
• the tubing forms a plug-in housing for the dip tube. It can thus be said that the tubing forms the extension or extension of the plunger tube forming a piston lip. It is not excluded, in the context of the invention, that the plunger tube forms the tubing.
• the tubing is connected to an outer casing so as to extend substantially concentrically inside the outer casing, the sleeve extending between the tubing and the outer casing, when the casing Fluid product applicator is mounted on the fixed mounting part.
• an annular receiving space is formed between the tubing and the outer casing, the sleeve being received in this space, when the applicator is in place on the fixed part.
• the outer casing forms drainage openings for discharging into the reservoir of fluid that would be present between the tubing and the outer casing.
• the fluid product is present at the mouth of the sleeve, once the application operation is complete, so that this fluid is introduced with the sleeve in the space formed between the tubing and the outer envelope.
• This fluid product can be evacuated through the openings of drainage directly into the fluid reservoir, so that there is no risk that the fluid product accumulates in the housing formed between the tubing and the outer casing.
• it can not create overpressure in this housing, since it is open on the tank. Indeed, such an overpressure could interfere with the repositioning of the applicator on the fixed mounting part.
• the fluid product applicator comprises a vent passage connecting the sampling chamber to the outside to evacuate the air present in the sampling chamber, when the fluid applicator is replaced on the fixed mounting part.
• the dip tube and the tubing filled with fluid product are not drained into the tank by the air pressurized in the sampling chamber. Therefore, during the next sampling phase, the sampling chamber is immediately filled with fluid, as soon as the piston lip begins to slide in the cylindrical inner wall of the sleeve.
• the vent passage is provided with a non-return valve allowing evacuation of air to the outside and preventing outside air from entering the sampling chamber. In this way, it is ensured that outside air does not reach the sampling chamber when the applicator is removed from the fixed mounting part.
• the fluid product applicator comprises a gripping member to which the sleeve is fixed, the gripping member advantageously forming a housing receiving a movable vent valve member adapted to come into sealing engagement on a vent valve seat formed by the sleeve.
• vent passage with or without valve
• any dispenser applicator with a sampling chamber formed inside and / or outside of the applicator.
• Vent passage (with or without valve) could be implemented in applicator devices documents FR2924696 and FR2978742. Individual protection could therefore be sought for these characteristics.
• the fixed mounting piece may comprise a wiper lip which comes into sliding contact with an outer wall of the sleeve. This spin lip may be used to close off the vent passage when the applicator is in place on the fixed mounting part.
• the invention also defines a fluid dispenser comprising a fluid reservoir and a fluid application device as defined above.
• the spirit of the invention is to define a sealed sliding shaft inside the sampling chamber and to provide the tubing which extends in the extension of the dip tube with a piston lip which comes into sliding contact waterproof with this sliding shaft.

It is also conceivable to form the fixing skirt 11 with an internal thread intended to cooperate with an external thread formed by the neck of the reservoir. Again, the type of hooking technique for mounting the mounting skirt 1 1 on the tank R is not critical for the present invention.

• the tubing 17 of the fixed mounting part 1 is engaged inside the sampling chamber C with its piston lip 19 in sealing contact with the cylindrical inner wall 2i of the sleeve. Since the fluid applicator A is removably mounted on the fixed mounting part 1, it is easily understood that the displacement of the applicator A relative to the fixed mounting part 1 has the effect of sliding the piston lip 19 against the cylindrical inner wall 2i.

The outer wall 2e of the sleeve can even come into contact with the inner wall of the outer shell 15. When a spin lip 14 is provided, it comes into sealing contact with the outer wall 2e of the sleeve 2.
• the fluid that would be present on the outer wall 2e would be scraped by the squeezing lip 14, and this product would fall to the bottom of the annular receiving space E where the passage openings 156 are formed, so that the fluid could return to the reservoir R.

In doing so, the piston lip 19 slides in the sleeve 2 on a stroke corresponding to the height of the thread between the flange 13 and the ring 32. Once unscrewing performed, the user will pull axially the applicator A upwardly to further extract the sleeve 2 from the annular receiving space E.
