Definitions

  • the present invention relates to an improved precompression pump, and more particularly a miniaturized pump, generally actuated using a finger, intended to spray fluid products, generally liquid or pasty, such as perfumes, pharmaceuticals or cosmetics.
  • a manual precompression pump is described in the document FR 2 403 465.
  • This type of pump comprises a hollow cylindrical pump body in which slides an annular piston, said piston being controlled by a push rod which slides in the pump body through a lateral opening.
  • the pump body and piston define a pump chamber, and the piston is movable relative to the push rod so as to close the lateral opening of the outlet channel or on the contrary to the put in communication with the pump chamber.
  • the piston is connected to the push rod by a precompression spring which biases the piston towards a position where said piston closes the lateral opening of the outlet channel.
  • the rod When the rod is pressed, it urges the piston towards the pump chamber by through the precompression spring, which creates a vacuum in the chamber pump. As the pressure on the push rod is increased, the pressure in the pump chamber increases and the precompression spring compresses. When a predetermined pressure prevails in the pump chamber, the spring precompression is sufficiently compressed for the piston to clear the lateral opening of the outlet channel, and the product contained in the pump chamber begins to be forced out.
  • the present invention aims to solve this technical problem.
  • the piston has a cylindrical surface axial interior open towards the pump chamber, said central sealing member slide with sealing in said inner cylindrical surface by insulating from the chamber pumping said central section of the piston, and said inner cylindrical surface extends axially towards the pump chamber over a distance such that the central member seal leaves said inner cylindrical surface when the piston is moved by a certain distance D2 relative to the push rod, from its rest position in direction of the outer end of the push rod.
  • the push rod has at least one sealing zone located axially at a location between the lateral opening of the outlet channel and the pump chamber, the piston slides with sealing on said sealing zone, in isolating the outlet channel with respect to the pump chamber, the piston leaves said zone sealing when it has moved axially by a distance D1 greater than D2 relative to the push rod, from its rest position towards the end outside of the push rod, and the outlet channel communicates with the pump chamber as soon as the piston has moved from said distance D1.
  • the pump may include a return spring for the push rod, and the pump may include an inlet valve for filling said chamber pump after each actuation of the pump.
  • said central sealing member is integral with the push rod.
  • the pumps described here are generally made of molded plastic, the seals are generally made of elastomer and the springs of metal.
  • Figures 1 and 2 show a first embodiment of the pump according to the invention.
  • the pump of Figures 1 and 2 is an improvement on the pump shown in FIG. 7b of European patent EP-0 486 378.
  • the pump comprises a hollow cylindrical pump body 1, having an axis of revolution 2.
  • the pump body 1 extends between an open upper end 1c, and a lower constriction 1a.
  • the constriction 1a is extended by an inlet duct 1b suitable for communicating with a reservoir containing product to be dispensed (not shown), directly or by a dip tube 1f.
  • the pump body 1 defines a pump chamber 6 which normally contains of the product to be distributed, and which communicates with the inlet conduit 1b via an inlet valve.
  • the inlet valve may for example comprise a conical seat 16 and a ball 15 adapted to apply sealingly on the conical seat 16 by closing the inlet duct 1b, when an overpressure is created in the pump chamber 6.
  • the ball 15 takes off from its seat 16 by opening the inlet duct 1b.
  • the inlet valve could have any other known form, without departing from the scope of the present invention.
  • the pump body 1 can be mounted on the neck of the product tank using a metal cup 10 set on the open upper end 1c of the body pump, said metal cup having a bottom 10a provided with a central orifice 10b.
  • the metal cup 10 also has a enlargement 10c, and an annular flat seal 31b is disposed between the enlargement 10c and the tank neck.
  • the piston 3 comprises an outer skirt 5, at least one periphery of which is in tight contact with the pump body 1.
  • the piston has a duct interior 3d axial.
  • the piston 3 further comprises an annular lower lip 4 which extends axially towards the throat 1a of the pump body and which is arranged in the center of the piston 3, around the inner duct 3d.
  • the pump comprises an axial push rod 40, centered on the axis 2, which crosses the orifice 10b of the metal cup.
  • the push rod 40 is formed in two parts, and comprises an outer sleeve 41 fixed to an inner core 42, by interlocking by force or by another means.
  • the outer sleeve 41 has a shape of revolution around the axis 2. It passes through the central orifice 10b of the metal cup 10, and extends outside the pump body 1, to an outer end or upper 41f, which can receive a pusher 43.
  • the pusher 43 allows both actuation of the pump and product outlet. As shown in Figure 1, the pusher can have a lateral outlet, possibly fitted with a spray 43a.
  • the sleeve 41 has a axial channel 41a which passes through it. From the outer end 41f, the sleeve 41 is extends to the inside of the pump body, to a collar 41c which extends substantially radially outward.
  • the sleeve 41 can be provided with a skirt 41d cylindrical, which extends towards the lower constriction 1a of the pump body to from collar 41c.
  • the cylindrical skirt 41d has an outside diameter smaller than the diameter collar 41c, and an inner diameter greater than the outer diameter of the inner core 42.
  • the inner core 42 has a first cylindrical part 42c which extends from an upper end 42f in the direction of the lower constriction 1a of the body pump.
  • the upper end 42f is fitted into the sleeve 41.
  • Said first cylindrical part 42c of the core 42 extends towards the lower constriction 1a of the body pump by a second portion 42d of greater diameter.
  • Said second part 42d is here frustoconical, widening upwards; it could possibly be cylindrical.
  • the core 42 AT from the upper end 42f, the core 42 is pierced with an axial blind channel 42a which communicates with the channel 41a of the outer sleeve 41, and which opens laterally, by at least one orifice 42b formed in the first cylindrical part 42c, in the vicinity from the second part 42d.
  • the central inner lip 4 of the piston is cylindrical, and has a cylindrical inner surface 4b having a internal diameter substantially equal to the external diameter of the second cylindrical part 42d of the core 42.
  • the lip 4 can slide in leaktight manner on said second part 42d.
  • the piston 3 has a cylindrical part 45 which extends axially towards the end 1c of the pump body, around the core 42.
  • Said cylindrical part 45 has an external diameter substantially equal to the internal diameter of the skirt 41d of the sleeve 41, so that said cylindrical part 45 slides with sealing inside the skirt 41d.
  • the cylindrical part 45 and the skirt 41d thus define a annular suction chamber 46, arranged around the core 42, which communicates with the orifice 42b, because the piston 3 is not in leaktight contact with the first part cylindrical 42c of the core 42.
  • This suction chamber will be seen later.
  • the core 42 extends radially outwards by a 42nd widening, which itself can extend towards the lower constriction 1a of the pump body by a skirt 42g.
  • the skirt 42g cooperates with axial ribs 1g, formed at inside the pump body 1 and which extend a certain distance from the lower constriction 1a of said pump body, to guide the core 42 in its movement inside the pump body.
  • the enlargement 42e of the core 42 comprises a ring 44, which extends axially from said widening 42 towards the piston 3, up to an end 44c close to the piston 3.
  • this ring is interrupted by radial cuts 44a, which extend axially over a certain distance from the end 44c of the crown 44, as shown in FIG. 2.
  • the piston 3 has an annular surface 3a radial between the skirt 5 and the lip 4. Under the effect of the precompression spring 47, said annular surface 3a is applied against the crown 44.
  • the crown 44 has an interior surface 44b frustoconical, which widens towards the upper end 1c of the pump body and which exerts a radial tightening force, by wedge effect, on the lip 4 when the crown 44 is in abutment against the surface 3a of the piston.
  • the tightness of the contact between the lip 4 and the second part 42d of the core 42 is reinforced, while the clamping force exerted by the crown 44 is precisely controlled by the stop of said crown 44 against the surface 3a of the piston, which avoids irreversible deformations or jamming of the piston lip 4.
  • the second part 42d of the inner core 42 is frustoconical, it forms an annular edge 50 projecting around the core 42. From this way, when the frustoconical surface 44b of the crown 44 exerts its clamping force radial on the lip 4 of the piston, said annular edge 50 exerts pressure on the lip 4 concentrated on an inner peripheral line of the lip 4. In this way, the tightness of the contact between said lip 4 and part 42d is improved.
  • the crown 44 further includes a collar 44d which extends radially outward.
  • the skirt 5 of the piston has a cylindrical inner surface 5a which extends axially from the bearing surface 3a of the piston towards the lower constriction 1a of the pump body.
  • the cylindrical surface 5a is extended by a frustoconical surface 5b which extends axially towards the lower constriction 1a of the pump body in widening radially outwards.
  • the pump includes a return spring 48 disposed between the widening 42e of the core and the lower constriction 1a of the pump body.
  • Return spring 48 biases the core 42 and therefore the whole of the push rod 40, towards the open end 1c of the pump body.
  • the collar 41c of the sleeve 41 is applied in abutment against the bottom 10a of the metal cup 10.
  • an annular seal 31a can be interposed between the collar 41c and the bottom 10a of the cup 10.
  • the piston 3 has slots or ribs 49 arranged substantially radially, on which the precompression spring 47 rests.
  • the precompression spring 47 is a helical spring, its turns end may be at rest included in a plane not perpendicular to the axis 2.
  • the spring 47 would tend to deform the piston, or at least the skirt outside 5 of the piston, by imposing on it a certain cant, that is to say a certain rotation around an axis perpendicular to axis 2.
  • the pressure exerted locally by the spring 47 on the ribs 49 is important, so that said ribs 49 deform in allowing the spring 47 to sink more or less into said ribs 49 in direction of piston 3.
  • the ribs 49 due to their deformation, are in contact with the spring 47 over substantially the entire periphery of its end turn.
  • the bearing force of the spring 47 is distributed over substantially all of the periphery of the piston 3, so that the piston 3 is not deformed.
  • the operation of the pump in FIG. 1 is as follows. At rest, the piston 3 is in abutment against the crown 44 and the collar 41c is in abutment against an annular seal 31a interposed between the collar 41c and the bottom 10a of the metal cup.
  • the pusher 43 When a user presses the pusher 43, it lowers the push rod 40 inside the pump body, which urges the piston 3 downwards, due to the spring of precompression 47.
  • the volume of the pump chamber 6 therefore tends to decrease, by so that an overpressure is created there which presses the ball 15 against its seat 16, insulating the pump chamber 6.
  • piston 3 cannot go down into the pump: only the push rod 40 therefore descends, and possibly the piston 3 rises slightly in the pump body.
  • section S1 is meant here the projection of the surface of the piston exposed to the pressure of the pump chamber, on a plane perpendicular to the axis 2 of the pump body.
  • the spray conditions are excellent, it can be possible, without reducing the quality of the spray, to slightly reduce the stiffness of the precompression spring of the pump according to the invention with respect to the stiffness of the precompression spring of a pump of the prior art.
  • the pump according to the invention thus becomes "softer" and easier to use than the precompression pumps of the prior art, insofar as it requires less effort from the user.
  • the lateral orifice 42b of the core 42 is drilled in the first cylindrical part 42a of said core, on which the piston 3 slides without sealing.
  • the edges of the orifice 42b have slight defects in molding, these do not hinder the sliding of the piston 3 on the core 42 at all. more, as there is a certain clearance between the piston 3 and the first cylindrical part 42a from the core 42, the expulsion rate of the product is improved.
  • the volume of the suction chamber 46 increases, and like the piston 3 slide without sealing on the first cylindrical part 42c of the core 42, the chamber suction 46 communicates with the orifice 42b, so that the increase in volume of the suction chamber 46 produces suction in the axial channel 42a of the core 42, in the channel 41a of the sleeve 41, and in the outlet passage of the pusher 43.
  • the product contained in the pusher 43 from dripping or oozing outside of said pusher during device storage, particularly when the product has a pasty consistency.
  • the return spring 48 of the push rod 40 could be mounted at the outside of the pump body, for example between a collar of the sleeve 41 and the bottom 10a of the cup 10.
  • the pump body 1 is pierced with an orifice air intake 18, located near the upper end 1c of said pump body.
  • the collar 41e is no longer in contact with the seal 31a, so that air can pass between the push rod 40 and the seal 31a. So, in the ascent phase of the piston 3, when the product is sucked from the reservoir towards the pump chamber 6, a volume of air equal to the volume of product drawn into the chamber pump can pass into the tank through the air return port 18.
  • the pump may not have an air intake orifice 18, without however, depart from the scope of the present invention.
  • the suction chamber 46 could be omitted, without going beyond the ambit of the present invention.
  • the expulsion of the product can start as soon as the seal between the collar 44a and the skirt 5 is broken, that is to say as soon as the piston has moved the distance D2 from the push rod.
  • the impulse effect given to the piston when this seal is broken still exists, since the piston cross-section exposed to the pump chamber pressure suddenly increases from S1 to S2.
  • the impulse given to piston 3 is less strong as in the example in figure 1, since the pressure in the pump chamber begins to decrease as soon as the seal between the collar 44a and the skirt 5 is broken, the expulsion of the product begins at this time.
  • the pump of figure 3 has a structure very similar to that of figure 1, and will not be therefore not described again in detail here.
  • This pump differs from that of Figure 1 in that it is intended to spray or dispense a single dose of product, contained initially in the pump chamber 6.
  • the pump in FIG. 3 does not have return air orifice 18. It also does not include the re-suction chamber 46 of the pump of FIG. 1, in which case the piston 3 slides with sealing on the core 42 of the rod 40. It will however be noted that the re-aspiration chamber 46 could possibly be kept as in figure 1, although the re-aspiration presents little interest in this case.
  • the pump of Figure 3 does not have a valve inlet 15, 16, nor inlet duct 1b, but only a filling passage 60 in the bottom 1a of the pump body, closed by a ball or other equivalent means.
  • the pump of Figure 4 is a variant of the pump of Figure 1, in which the collar 44a of the crown 44 slides no longer inside the skirt 5 of the piston, but inside a cylindrical axial wall 5c concentric with the skirt 5.
