Definitions
- the present invention relates to a pump and more specifically a pump for the delivery in spray form of perfumes or cosmetic products or low doses of pharmaceutical products.
- pumps comprising a substantially cylindrical body intended to be fixed on a container and internally delimiting a metering chamber for the product to be dispensed.
- the lower end of the body is provided with an inlet orifice equipped with a valve and its upper end is, on the one hand, provided with an exhaust orifice and, on the other hand, is closed by a piston.
- This piston is capable of moving in the metering chamber, by cooperating with elastic return means, between a high rest stop and a low end stop. Upon priming, the first descent of the piston causes an air flush, then its ascent causes the filling of the metering chamber with the product.
- the following displacements of the piston are accompanied, on the descent, by a spraying of product outside, via the exhaust port, under the effect of the hydraulic pressure, and, on the ascent, of a product aspiration into the chamber via the intake port.
- either these pumps include seals made of elastomeric material which cause odor nuisances for the product, in particular when the latter is scented, or they do not include any, and the seal is not sufficient. , in particular, for very volatile products.
- the present invention aims to satisfactorily solve the technical problems posed by the prior art.
- a pump of the type comprising a substantially cylindrical body internally defining a metering chamber, the lower end of which is provided with an inlet orifice equipped with a valve and the upper end of which is provided, on the one hand, with an exhaust orifice and, on the other hand, is closed by a piston capable of moving in said chamber, by cooperating with elastic return means external to the chamber, between an upper rest stop and a lower end stop, said piston comprising a central core secured to the lower end of an axial hollow rod whose upper end projects outside the chamber metering and a coaxial sleeve, connected to said rod by an elastic articulation ensuring, on the one hand, a tight contact with the internal wall of the chamber and delimiting, on the other hand, with said core, a conduit annular discharge capable of being opened by displacement of said sleeve relative to the core and the upper part of the pump body being closed by a flange, the internal face of which, on the one hand,
- said sleeve includes a flared lower skirt whose internal face opposite the core is provided with a peripheral ring intended to be, in the position for closing the evacuation duct, in sealed contact with said core.
- said articulation comprises a central collar mounted by radial clamping on the periphery of said axial hollow rod and connected to the sleeve by an elastically deformable spacer.
- the flange consists of a central sleeve provided with a latching member in the part upper body and a peripheral flange for fixing to the upper edge of said body.
- said hollow rod and said core are made in one piece.
- said hollow rod is separated from the core by transverse channels supplied by the evacuation duct.
- said axial hollow rod is connected, externally to the metering chamber, to a spray tube.
- the spacer of the articulation of the bushing is disposed substantially opposite the outlet of the transverse channels and comprises undercuts.
- the spray tube carries a peripheral shoulder delimiting an upper bearing face for the return means of the piston.
- said shoulder is extended downwards by a cylindrical wall moving in a guided manner in said central sleeve of the collar which defines with said wall a housing for said return means.
- the body has an orifice forming a vent located, in the high position of the piston, above the lower edge of the sleeve.
- said sleeve may have a bevelled end ensuring tight and scraping surface contact with the internal wall of the metering chamber.
- the lateral face of the core and the internal face opposite the sleeve are parallel and inclined relative to the axis of the pump.
- said core has a frustoconical lower part capable of being housed in a cavity with a complementary profile formed in the lower part of the body, below the level of the lower stop of the piston, to allow forced opening of the evacuation duct to the priming.
- the pump of the invention has a very high degree of tightness without using a seal, which makes it compatible on the olfactory level with perfumes and perfumed cosmetics.
- the tightness obtained is such that the pump of the invention can be used upside down without causing any product leakage.
- the assembly of the various constituent elements of the pump can be carried out in a simple and single operation, which allows complete automation of the manufacturing and packaging stages and leads to productivity gains.
- the piston return means are placed outside the metering chamber, which makes it possible to reduce the bulk of the part of the pump body internal to the container and to condition a larger quantity of product in a container of the same volume.
- FIG. 2a and 2b show respectively integral and detailed sectional views of the pump of Figure 1 in the open position, during a spraying phase;
- FIG. 3 shows a sectional view of the pump of Figure 1 at the end of spraying
- FIG. 4a and 4b show respectively integral and detailed sectional views of the pump of Figure 1 in the priming phase.
- the pump shown in Figure 1 is intended for the distribution of perfumes or cosmetic and pharmaceutical products from a container.
- This pump comprises a substantially cylindrical body 1 internally delimiting a metering chamber 11.
- the body 1 of the pump is intended to be fixed in leaktight manner on the neck C of the container.
- the lower end 1a of the body 1 is provided with an intake orifice 10 equipped with a valve 12, here in the form of a ball.
- the upper end 1b of the body 1 is made open to allow the introduction of a piston 2 and is provided with an exhaust orifice 20a.
- the orifice 20a opens into a closable conduit 20 for the evacuation of the product from the chamber 11.
- the piston 2 is capable of moving in the chamber 11 between an upper rest stop and a lower end stop, while being returned to the rest position by a helical spring 4 disposed outside the chamber 11.
- the piston 2 comprises a central core 21 integral with the lower end 23a of an axial hollow rod 23, the upper end 23b of which projects outside the chamber 11.
- the rod 23 and the core 21 are made in one piece.
- the core 21 is surrounded coaxially by a socket 22 produced in the form of an insert and connected to the rod 23 via an elastic joint 24.
- the core 21, the rod 23 and the sleeve 22 are made in one piece.
- the sleeve 22 ensures, on the one hand, a tight contact with the internal wall of the chamber 11 and delimits, on the other hand, with the core 21 the annular duct 20
- the sleeve 22 has a flared lower skirt 22a whose internal face, facing the core 21, is provided with a peripheral ring 220.
- the ring 220 is intended to be, in the closed position of the conduit 20 ( Figures 1 and 3 ), in tight contact with the core 21.
- the hollow rod 23 is separated from the core 21 by transverse channels 230 supplied by the evacuation duct 20.
- the lateral face of the core 21 and the internal face opposite the sleeve 22 are parallel and inclined relative to the axis of the pump.
- the articulation 24 comprises a central collar 24b mounted by radial tightening on the periphery of the hollow rod 23 above the core 21.
- the collar 24b is connected to the bush 22 by an elastically deformable spacer 24a allowing the relative displacement of the bush 22 relative to the core 21.
- the bush 22 also includes an upper ring 22b which extends in the extension of the lower skirt 22a; the spacer 24a ensuring the separation between the skirt 22a and the crown 22b.
- the upper body part 1 of the pump is closed by snap-fastening a flange 3, the internal face of which forms the upper stop of the piston 2 and the external face serves as a lower support for the spring 4.
- the flange 3 consists of a central sleeve 33 provided with an axial bore 30 in which the axial hollow rod 23 moves, integral with the piston 2.
- the collar 24b has a height substantially equal to that of the bore 30, and the respective profiles of the upper edges of the bore and of the collar are complementary.
- the crown 22b of the sleeve 2 is, in the rest position of the pump shown in FIG. 1, engaged in sealed abutment in a peripheral groove 31 formed on the internal face of the collar 3.
- the crown 22b has an internal face slightly inclined towards the axis of the pump while its external lateral face is substantially parallel to this axis.
- the internal flank 31a of the groove 31, opposite the internal face of the crown 22b, has a slight curvature towards the axis of the pump to ensure sliding contact of the opposite faces, l 'one on the other and a guide of the crown 22b in the groove 31 towards the high stop position.
- the end of the internal flank 31a of the groove 31 is in abutment, with sealed contact, against the upper face of the spacer 24.
- the upper stop of the piston 2 therefore corresponds to a double level of tightness vis-à-vis -visual eventual product infiltration that may occur through the vent orifice 13, located above the lower edge of the skirt 22a, in the high stop position of the piston 2.
- the groove 31 forms a retention zone making it possible to collect any product flows which penetrate inside the chamber 11 via the orifice 13.
- the central sleeve 33 of the collar 3 is provided with 'an organ 33a watertight latching in the upper part lb of the body 1 and a peripheral flange 33b for fixing to the upper edge of the body 1.
- transverse channels 230 open laterally on the rod 23 and facing the elbow 24c connecting the collar 24b and the spacer 24a of the articulation 24.
- the axial hollow rod 23 is connected, outside the metering chamber 11, to a nozzle tube 5, for example, by fitting and snap-fastening.
- the tube 5 carries a peripheral shoulder 51 which delimits an upper bearing face for the spring 4.
- the shoulder 51 is extended downward, towards the flange 3, by a cylindrical wall 52 moving in a guided manner with a slight play in the central sleeve 33 which defines with the wall 52, a housing 54 for the spring 4.
- the skirt 22a of the sleeve 22 has a beveled end with an external face 220a which ensures sealed surface contact of the piston 2 with the internal wall of the metering chamber 11 during its movements.
- the chamber 11 is filled with product and the thrust is transmitted by the incompressible liquid product to the walls of the chamber 11 and in particular to the skirt 22a of the articulated bush 22.
- the sleeve 22 is the only movable element in the chamber 11. The thrust exerted on the sleeve 22 then causes it to move upward along the internal wall of the chamber 11 by elastic deformation of the articulation 24 ( see figure 2b).
- the peripheral ring 220 finds its support on the core 21 and thus closes the conduit 20.
- the relaxation of the head T and of the nozzle tube 5 is accompanied by the relaxation of the spring 4, of the guided outlet of the wall 52 from the top of the sleeve 33 and of the ascent of the piston 2 in the chamber 11 by sucking in product into the container through the orifice 10 via the valve 12 in the open position.
- FIG. 4a and 4b relate to the priming phase of the pump.
- the container R contains product but the metering chamber 11 only contains air.
- the first descent of the piston 2 therefore has the effect of compressing the air in the chamber 11. From a determined value of overpressure, the sleeve 22 moves in translation upwards and the rod 220 moves away from the core 21 by opening conduit 20.
- the compressed air then escapes to the outside through the conduit 20, the channels 230, the rod 23, the tube 5 and the nozzle B. All the air present in the chamber 11 is evacuated by forced opening of the duct 20 because the core 21 has a frustoconical lower part 21a capable of being housed in the cavity 15 with a complementary profile located below the level of the lower stop 14 of the piston 2.
- the lower abutment of the piston 2 leaves the duct 20 open for a short period which corresponds to the time necessary for degassing of the cavity 15.
