Definitions

• the present invention relates to a distributor of liquid products and more particularly of perfume samples.
• the miniature distributors known up to now generally comprise a pump, the body of which, tightly fitted in said neck, contains a piston cooperating by means of a return spring with an intake valve and an exhaust valve.
• the piston carries an external rod delimiting an internal evacuation duct and a dispensing head covering said piston rod and carrying an ejection orifice.
• the present invention aims to simplify the structure of these distributors and their manufacturing and assembly methods by reducing the number of component parts while improving the efficiency and quality of their operation.
• This object is achieved, according to the invention, by means of a distributor of the preceding type, characterized in that said piston rod is extended, in the upper part, by a core delimiting, in a complementary manner, with the internal wall of the distribution head, on the one hand, an outlet channel supplied by the evacuation duct and, on the other hand, a vortex spray system into which said channel opens.
• said head has a lateral skirt provided at the bottom with a separable peripheral strip ensuring its locking in the low position by hooking an internal projection in a retaining element formed on the external wall of the tank.
• the neck of said reservoir has a peripheral flange under which the internal projection of the separable strip hangs.
• the wall of the reservoir has a peripheral groove in which the internal projection of the separable strip comes to hang.
• said intake and exhaust valves consist respectively of a plug and a needle carried by a single shutter, movable in axial translation inside the pump body and around which the return spring is mounted .
• said needle is formed from the frusto-conical upper end of the obturator which is intended to come, in the intake phase, in sealed abutment against an angular edge of the lower end of the evacuation duct delimiting a zone of circular contact.
• said plug is formed of a cylindrical lower portion of the shutter which is intended to slide in leaktight manner in a bore of said body and over a height of which is formed at least one groove allowing the passage of the product in phase d 'admission.
• the diameter of the circular contact area of the edge with the pointer is less than the inside diameter of the bore of the body.
• said shutter comprises a shoulder for the setting of said return spring.
• said piston comprises a peripheral ring intended to abut upwards against an annular lip carried by the upper edge of the pump body, while said pump body has an annular upper flange bearing on the tank neck.
• the dispenser of the invention comprises a limited number of parts made of plastic, including the reservoir, the manufacture and assembly of which by molding are simple, rapid and economical.
• FIG. 1 represents a sectional view of an embodiment of the dispenser of the invention before its first use.
• FIG. 2 shows a sectional view of the dispenser of Figure 1 after removal of the separable strip.
• Figure 3 shows a sectional view of the dispenser of Figure 1 in the product distribution phase.
• the dispenser shown in the figures comprises a reservoir 1 provided with a neck 10 in which is enclosed a liquid product such as a perfume.
• a precompression pump with a cylindrical-conical body 2 is mounted on the tank 1.
• the body 2 is fitted with tight radial tightening in the neck 10 in the manner of a plug.
• the body 2 has an annular upper flange 21 which bears on the rim of the neck 10 thereby limiting the penetration of the body 2 into the reservoir 1 and by adjusting the position of the dip tube 22 (partially shown) relative to the level of liquid.
• the body 2 contains a cylindrical piston 3 cooperating by means of a return spring 4, with an intake valve and an exhaust valve and delimiting with the wall of the body a metering chamber.
• the piston 3 carries an external rod 31 internally delimiting a discharge conduit 30 extending the metering chamber upwards.
• the rod 31 is surmounted by a dispensing head 7 forming a push button which carries an ejection orifice 70.
• the rod 31 is extended, in the upper part, by a core 33 delimiting in a complementary manner with the internal wall of the head 7, on the one hand, an outlet channel 37 fed by the evacuation duct 30 and, on the other hand part, a vortex spray system 38 in which opens the channel 37.
• the channel 37 extends here as far as the upper periphery of the core 33.
• the rod 31 and the core 33 form a single piece.
• This vortex system 38 which communicates outside, via the orifice 70, is constituted by the facing of a network of grooves carried by the front face of the core 33 with a sealing face carried by the internal wall of the head 7 around orifice 70.
• the abutment upward of the core 33 inside the head 7 automatically ensures the tight connection of the conduits, channels and nozzle without the need to provide an indexing of the facing pieces.
• the head 7 has a lateral skirt 71 provided, in the lower part, with a peripheral band 6 ensuring its locking in the low position.
• the strip 6 can be separated from the head by being attached to the skirt 71 by a weakening zone 61 capable of being broken or detached by traction by means of an end tab 63.
• the strip 6 carries a continuous or discontinuous internal projection 62 which is engaged with the external wall of the tank 1 by hooking in a retaining element.
• the retaining element is formed by a collar 11 of the neck of the reservoir 1 delimited in the drawings by a reduction in thickness of the wall of the reservoir 1 or according to another variant (FIGS. 1 to 3), this element is formed on the body of the reservoir in the form of a groove 12.
• the inlet and exhaust valves consist respectively of a plug 51 and a needle 52 carried by a single shutter 5 which is movable in axial translation inside the pump body 2, and around which the spring 4 is mounted
• the body 2 is provided with an internal sleeve 24 coaxial delimiting, on the one hand, with the side wall of the body, a cylindrical zone in which the piston 3 is guided and, on the other hand, with the shutter 5 a central housing for the spring 4.
• the needle 52 is formed from the frustoconical upper end of the shutter 5 which is intended to come, in the intake phase, in sealed support contact against an angular edge 32 of the lower end of the evacuation duct 30.
• the plug 51 is formed, in turn, of a cylindrical lower portion formed on the shutter 5 which is capable of sliding in leaktight manner in a bore 20 of the body 2 of the pump.
• a groove 51a is however made over a height of the cylindrical portion to allow, in the intake phase, the passage of the product by suction from the reservoir 1.
• Another embodiment, not shown, would consist in providing on this same height of the cylindrical portion, a constriction of diameter allowing the passage of the product.
• the shutter 5 also includes a shoulder 54 for setting the spring 4.
• the height of the shutter 5 is such that it occupies, in the low position of the piston, almost the entire internal volume of the dip tube 22, leaving only 'a slight clearance, as shown in Figure 1, where the head is held in the low position against the biasing forces of the spring 4. This arrangement allows rapid priming of the pump since the capacity of the dip tube is reduced then that its own dimensions (height and diameter) remain normal.
• the device In this rest position, the device is sealed against the exhaust valve by lightly pressing the needle 52 against the core 33.
• the piston 3 comprises a peripheral ring 34 intended to abut upwards against an annular lip 23 carried by the upper edge of the body 2 of the pump.
• the lip 23 is a deformable lip which can be folded outwards to allow the body to be ejected from the mold during manufacture and which is subsequently folded inwards.
• the pressure increases in the metering chamber until the exhaust valve gives way and lets the product pass to the duct 30.
• the setting of the exhaust valve is adjusted by an appropriate choice of materials and dimensions of the contact area between the needle 52 and the lower edge 32 of the duct 30, so that it can open once the valve admission closed.
• the contact area between the needle 52 and the edge 32 is circular and its diameter is less than the inside diameter of the bore 20 of the body 2.
