Definitions

  • the present invention relates to a device for dispensing product contained in a container, and more particularly to a precompression pump.
  • Current pumps generally comprise a pump body comprising a pump chamber, an inlet valve, an outlet valve, a piston sliding in said pump body and an actuating rod for activating the pump by means of a pusher.
  • Current precompression pumps generally also include a differential piston forming an outlet valve and sliding in the pump body or on the actuating rod, under the effect of a precompression spring.
  • the object of the present invention is to provide an improved precompression pump, which does not have the abovementioned drawbacks.
  • the present invention aims to achieve a new precompression pump consisting of fewer parts than current pumps, and therefore cheaper to manufacture and easier to assemble.
  • the present invention aims to provide such a pump comprising only one spring and not comprising an actuating rod.
  • the present invention also aims to provide a new precompression pump whose height is reduced.
  • the invention aims to provide such a pump in which the dead volume is minimized.
  • Another object of the present invention is to provide such an improved precompression pump in which the volume of the dose expelled on each actuation can be modified by the user, without increasing manufacturing costs.
  • a subject of the invention is therefore a precompression pump for selectively dispensing a product contained in a container, said pump comprising a pump chamber comprising an inlet valve, a piston sliding in a first cylinder, a differential piston forming a outlet valve of said pump chamber, and sliding in a second cylinder between a closed position and an open position of the pump chamber, said pump further comprising a pusher provided with a dispensing orifice, said pusher being movable between a rest position and a pump actuation position, characterized in that said first and second cylinders are directly formed by respective first and second inner walls of said pusher, said pusher thus partly defining said pump chamber , and in that said pump comprises only one spring resting on one side on a part of the pusher and on the other side on a part of differential piston, said spring acting on the one hand as return spring of pusher toward its position rest, and secondly as a precompression spring for the differential piston.
  • the pump according to the invention has the advantage of eliminating in particular the actuating rod and one of the two return and precompression springs.
  • the height of the pump and the dead volume are therefore greatly reduced, the pump chamber and the single spring being located inside the pusher, and the number of component parts of the pump is reduced, so that its manufacture and its assembly are more economical, both from the point of view of time and from the point of view of cost.
  • said piston is fixed relative to the container.
  • said pump comprises a fixed part intended to be fixed on the neck of the container, said fixed part partly delimiting the pump chamber and incorporating said piston, said pusher sliding in leaktight manner on said fixed part.
  • said fixed part also forms the seat of said inlet valve of the pump chamber, said fixed piston being formed by an annular lip of said fixed part sliding in leaktight manner in said first cylinder of said pusher.
  • said fixed part further comprises means for fixing the pump to the neck of the container.
  • said fixed part further comprises means for fixing the pump to the neck of the container.
  • said means for fixing the pump to the neck of the container are latching lugs intended to snap onto said neck of the container, and cooperating after their latching, with a hoop which is intended to be mounted around said lugs for maintain said fixed part fixedly on the neck.
  • said hoop after its mounting on the fixed part, cooperates at its upper end with the pusher to form a stop defining the rest position of said pusher.
  • said hoop after being mounted on said fixed hoop, is movable relative to the latter between two limit positions to define at least two different pump chamber volumes. The user can thus adjust as desired the volume of the dose of product which will be expelled on each actuation.
  • the mounting and / or movement of said hoop on said fixed part is carried out by screwing.
  • FIG. 1 is a schematic sectional view of a pump precompression according to the invention, in its rest position
  • Figures 2 and 3 are schematic views similar to Figure 1, showing a variant of the invention incorporating a hoop for adjusting the volume of the dose expelled.
  • the precompression pump comprises a piston 1 which slides in a first cylinder 2 formed directly in the pusher 6.
  • the pump comprises a differential piston ensuring the precompression and sliding in a second cylinder 11 also formed directly in the pusher 6.
  • the pump chamber 3 is therefore located partly inside the pusher 6.
  • the piston 1 is preferably fixed and advantageously forms an integral part of a fixed part 20 which is fixed on the neck of the container (not shown), for example by means of latching lugs 22 and a hoop 21, which comes to be mounted around said lugs 22.
  • This fixed part 20 therefore acts on the one hand as a pump body by partially delimiting the pump chamber 3 , and by receiving for example a ball 4 to form its inlet valve.
  • the fixed part 20 forms, by an annular lip, the piston 1.
  • it also advantageously acts as a fixing ring.
  • said annular lip forming the piston 1 slides in leaktight manner in said first cylinder 2 formed directly by an interior wall of the pusher 6.
  • the differential piston 5 slides in said second cylinder 11 formed directly by an interior wall pusher 6, between a closed position, where it closes the passage 8 between the pump chamber 3 and the dispensing orifice 7, for example a nozzle, and an open position, where it opens said passage 8.
  • the pump of the invention therefore has the advantage of operating in the same way as a conventional pump, while incorporating fewer component parts.
  • the height of the pump is greatly reduced.
  • the single spring 15 of the pump located in the pusher minimizes the dead volume in the pump.
  • the hoop 21 is movable relative to the fixed part 20, after having been mounted thereon.
  • the rest position of the piston and therefore the volume of the pump chamber 3 can be modified or adjusted by the user.
  • the hoop 21 can be moved by screwing between two limit positions shown in FIGS. 2 and 3, but any other known means of moving the position of the hoop 21 relative to the fixed part 20 is conceivable (for example moving axial).
