Definitions

  • FIG. 4 of FR-A-2 346 056 discloses a manual precompression pump.
  • a pump for spraying a liquid under pressure, a pump has already been proposed, as for example described in FR-A-2 460 164, in which the lower piston has a central passage, in which, substantially at mid-length, arms extend radially and form a sort of star, these arms carrying a central rod coaxial with the piston, of smaller diameter, elastic return means for the cylinder and of the lower piston being constituted by a helical spring, one end of which is engaged in the central passage of the piston and bears against the radial arms, and the other end of which bears against a stop integral with the internal wall of the body.
  • the diameter of the lower part of the pump can be reduced so that a large part of the pump can be engaged in the mouth, which reduces the projection on the container.
  • the flow of liquid under pressure, during spraying takes place through longitudinal passages, without appreciable constriction, and therefore with reduced pressure losses.
  • priming the pump requires a minimum of effort, in terms of handling the pusher; for this, decompression means are provided to break the seal established by the lower piston at the end of the stroke and allow, in particular, the evacuation of air for priming the pump and filling the cylinder with liquid; unfortunately, the decompression means, generally constituted by grooves or fins formed on the internal wall of the cylinder over which the piston is caused to pass, end up damaging the piston.
  • the lower piston is formed by a sleeve comprising a central passage, this sleeve comprising, at its end facing the non-return suction valve, a skirt frustoconical sealing suitable for pressing against the internal surface of the body and, at its other end, another sealing skirt also suitable for pressing against the internal surface of the body, while at least one hole is provided in the wall of the body, in particular for the evacuation of air during priming of the pump, this hole being positioned so as to be permanently in the annular space comprised between the two sealing skirts of the piston inferior.
  • the wall of the body may include, above the first hole, a second air intake hole.
  • the discharge valve is arranged to open in the opposite direction to the flow of liquid so as to completely free the inlet of the cylinder outlet pipe, the inlet which constitutes the seat of the valve.
  • This discharge valve comprises a body sliding in a sealed manner in a housing of the piston-carrying element of smaller diameter and a cup sliding in a sealed manner in the chamber of the cylinder of larger diameter, the valve being traversed by at least one longitudinal channel connecting its two faces, so that a differential effect of the pressure, which acts on different surfaces between the top and the bottom of the discharge valve, controls the opening of this valve.
  • the discharge valve is returned by a helical spring arranged between the bottom of a housing provided in the piston-carrying element and the discharge valve.
  • the pump is equipped with a spray nozzle suitable for creating a vortex, this nozzle comprising a cap pierced with an orifice, mounted on a radial stud, a liquid supply channel being provided between the stud and the cap. to open in an annular space, while supply channels connect this annular space to the orifice; the supply channels have a prismatic shape whose section decreases from the annular space to the periphery of the orifice.
  • the supply channels can be formed in the bottom of the cap and delimited laterally by the flat front face of the stud, the annular space being provided in the front face of the stud and delimited by the peripheral bottom of the cap.
  • Figure 1 of these drawings is a perspective view of a pump according to the invention during assembly on the mouth of a container, the pusher not yet in place on the pump.
  • Figure 2 is a vertical axial section of the pump according to the invention, in the rest position.
  • Figure 3 is a view similar to Figure 2, showing the pump being primed, with the plunger fully depressed.
  • Figure 4 shows, similarly to Figure 2, the pump with the partially depressed plunger, during spraying.
  • Figure 5 is an enlarged section of a detail of the spray nozzle.
  • FIG. 6, finally, is a view along line VI-VI of FIG. 5.
  • the pump 1 comprises a body 4 intended to be fixed on the mouth 3.
  • the body 4 is formed, in the example considered, by a succession of cylindrical parts 5, 6, 7, 8, 9 of increasingly larger diameters reduced when moving from top to bottom, as shown in Figures 1 and 2.
  • the upper part 5 comprises, at its upper end, a flange 10 projecting radially outwards, suitable for compressing a sealing washer 11 against the end of the mouth 3.
  • the tightening of the flange against the washer 11 is provided by a sleeve 12, having an internal thread suitable for cooperating with that of the mouth 3, which it comes to cap.
  • the lower extreme part 9 of the body 4 has the smallest diameter and constitutes a connection piece for a dip tube 13.
  • the transition zone between the lower extreme part 9 and the preceding part 8 is constituted by a frustoconical wall 14 whose surface internal constitutes the seat of a non-return suction valve formed by a ball 15.
  • a cylinder 16 is able to slide in the upper part 5 of the body under the action of a thrust exerted on a button 17 forming a pusher, against elastic return means formed by a helical spring 18.
  • the cylinder 16 has, at its upper part, a tube 19, of reduced diameter, connecting to a spray head 20 provided in the push-button 17.
  • a discharge valve 21 is arranged in the cylinder 16, with the possibility of sliding in the axial direction of this cylinder.
  • the discharge valve 21 includes a central frustoconical stud 22 suitable for being applied to the inlet 23 of the pipe 19, which constitutes the seat of this valve.
  • the upper part of the valve 21 comprises a cup 24 capable of sliding in leaktight manner against the internal wall of the cylinder 16; the valve 21 is extended downwards by a core 25 of smaller diameter than the cup 24.
  • This core 25 is provided at its lower part with a skirt 26 suitable for establishing a sealed sliding of the core in a cylindrical housing 27 of a piston-carrying element 28 linked, in particular by snap-fastening, to the cylinder 16.
  • the valve 21 is crossed by at least one longitudinal channel 29 connecting its lower face to the upper face limited by the cup 24.
  • the valve 21 is urged to close by a helical spring 30 disposed between the bottom of the housing 27 and the bottom of an annular recess provided in the lower part of the valve 21.
  • valve 21 is urged to close in the direction of flow of the liquid which takes place from bottom to top.
  • the valve 21 will open under the differential action of the pressure exerted on the larger surface of the cup 24 and on the smaller section of the core 21.
  • the pin 22 completely clears the passage of tubing 19 so that the pressure drops are reduced to a minimum.
  • the piston-carrying element 28 is traversed by a cylindrical longitudinal passage 31 at its lower part, and continuing upwards, in a decreasing section, in particular cruciform, whose diameter of the circumscribed circle gradually decreases.
  • the bottom of the housing 27 includes stop elements 32 surrounded by one end of the spring 30 and serving as centering at this end, these stop elements 32 being traversed by the extension of the passage 31 and being separated from each other by radial slots f , at least one of which is situated substantially in line with a channel 29. Under these conditions, when the valve 21 comes to bear against the stop elements 32, a relatively direct passage remains for the liquid towards the channel 29.
  • the diameter of the piston-carrying element 28 is such that this element can slide inside the part 6 of the body 4.
  • the lower part of the piston-carrying element 28 is formed by a kind of tube 33 of diameter reduced, comprising, on its outer surface connecting means, for example a thread, with a lower piston 34.
  • This lower piston 34 is formed by a sleeve crossed by a central longitudinal passage 35.
  • the piston 34 comprises, substantially halfway along its central passage, arms 36 extending radially and forming a kind of star.
  • the arms 36 carry a central rod 37 coaxial with the sleeve, with a diameter less than the diameter of the tube 33.
  • the rod 37 of the lower piston 34 plays a particular role: it allows, in fact, to refocus the spring 18 to prevent it, due to its length, from undergoing buckling.
  • the piston 34 comprises, at its lower part, sealing means formed by a frustoconical sealing skirt 38 suitable for pressing in a sealed manner against the internal wall of the part 7 of the body 4.
  • the piston 34 has, at its upper end, another sealing skirt 39 capable of pressing against the internal surface of the part 6.
  • a hole 40 is provided towards the lower end of the part 6, slightly above the constriction of the connection between the part 6 and the part 7. This hole 40 is positioned so as to be permanently in the space annular between the two skirts 38 and 39, that the piston 34 occupies the high position of FIG. 2 or the low position of FIG. 3.
  • Another air intake hole 41 can be provided towards the upper end of the part 6. This hole 41 is located below the skirt 39, when the piston 34 occupies the high position of FIG. 2, and at above this skirt 39 when the piston 34 is in the low position of FIG. 3.
  • the return spring 18 is engaged in the piston 34 to bear against the star formed by the arms 36. At its other end, the spring 18 bears against a seat s , projecting radially towards the inside of the internal surface of the part 8.
  • This seat inside which the ball 15 can be move, has at its upper part an internal rim adapted to retain the ball 15, while it is spaced from the wall 14.
  • Part 7 comprises, at its lower end, on its internal surface, a decompression bearing 42 formed in particular by longitudinal ribs, angularly spaced from one another, projecting inwards.
  • a decompression bearing 42 formed in particular by longitudinal ribs, angularly spaced from one another, projecting inwards.
  • the skirt 38 of the piston 34 is not damaged by the decompression bearings 42, the latter is made of a relatively flexible material, such as LDPE (low density polyethylene).
  • the upper piston 21 is made of the same material.
  • the piston-carrying part 28 is made of a relatively rigid material, such as polypropylene or HDPE (high density polyethylene).
  • Parts 28 and 34 are therefore molded separately and are independent of each other.
  • the spray head 20 will now be considered in more detail:
  • this head comprises the pusher 17 fitted on the pipe 19 and coming into abutment against an extension of the outer wall of the cylinder 16.
  • the head 20 comprises a central pin 43 of diameter less than the upper end the tube 19 in which it is engaged to determine annular passages allowing the liquid to reach the outlet nozzle 44.
  • This nozzle 44 comprises a cap 45 (see FIG. 5), pierced with a central orifice 46 centered at the top of a frustoconical cavity.
  • the cap 45 is threaded onto a radial stud 47 of the head 20.
  • a channel 48 for the arrival of the liquid to be sprayed is provided between the radial stud 47 and the cap 45 to open into an annular space 49 provided at the front end of the stud 47.
  • This annular space 49 is connected to the central hole 46 by channels 50 (FIG. 6) provided in the bottom of the cap 45.
  • the channels 50 are limited by two converging walls, substantially tangent to the circumference of the base of the hole 46, so that the section of each channel decreases from the annular space 49 to the circumference of the frustoconical cavity.
  • the channels 50 are delimited, laterally, by the flat front face of the stud 47.

  • the user must, first of all, in a conventional manner, prime the pump, that is to say ensure the filling the body 4 with liquid, the air being expelled.
  • the user must press several times, generally three or four times on the push button 17.
  • the frustoconical skirt 38 of the piston 34 meets the decompression bearing 42, which causes the seal to break and allows the compressed air to escape around the skirt 38 in the annular passage located outside the piston 34, and to pass, through the hole 40, into the container 2.
  • the spring 18 causes the piston 34 and therefore the cylinder 16 and the pusher 17 to rise.
  • a depression is created in the body 4, and in particular in the part 7, which causes the opening of the suction valve 15 and the rise of a certain amount of liquid in the body 4.
  • the valve 21 will open as soon as the pressure acting on the differential section of the valve is sufficient to overcome the action of the spring 30.
  • the pressurized liquid will then flow through the tubing 19 towards the nozzle 44 and will be sprayed.
  • the valve 21 is stopped by a frank support against the stop 32, which contributes to a good regularity of dose.
  • the displacement of the valve 21 takes place without causing displacement of the piston 34 and the spring 30 is chosen only as a function of the opening pressure desired for the valve 21.
  • the difference in section between the cup 24 and the core 25 of the valve can be chosen according to the type of operation desired for the valve 21.
  • the pump of the invention also has a great smoothness of operation, as well as a sudden drop in the handling force F (exerted on the pusher 17) that the user encounters at the end of the stroke.
