Definitions

  • the invention relates to a precompression pump for spraying under pressure a liquid, and in particular a cosmetic product such as a hair spray.
  • the invention aims, in particular, to provide a pump of this kind, manually operable and compact, so that it can be housed in the cover of a liquid dispenser cover.
  • Document EP-A 0 437 131 discloses, in the name of the applicant, a manual precompression pump, comprising, inter alia, a liquid pumping chamber in communication with a precompression chamber, a spray nozzle connected by a distribution channel to the precompression chamber, and a supply channel provided with a non-return valve opening into the pumping chamber.
  • the precompression pump of the kind described in EP-A 0 437 131 deserves to be improved from the point of view of spraying precision, since the actuation of this pump is carried out by pressing a button. pusher which at the same time includes the spray nozzle. As a result, the location where the spray is to be applied is difficult to target.
  • this known pump is difficult to assemble.
  • all the constituent parts of this pump are aligned on the same axis of symmetry, its bulk in the axial direction is relatively large, which prohibits its use in many embodiments employing a covering hood.
  • This pump has the drawback of containing a high number of constituents. In addition, it is difficult to assemble industrially. The cost price of such a pump is therefore relatively high.
  • the connection between the pumping chamber and the precompression chamber is constituted by a relatively long conduit, having several angles. As a result, there is a pressure drop in the liquid pressure during dispensing, resulting in poor spray quality;
  • a one-way valve is provided in this conduit, which further increases the pressure drop, thus requiring considerable effort for the user to actuate this pump.
  • this pump has a large size; therefore its use cannot be envisaged for all needs, in particular for the distribution of liquids contained in containers of small capacity.
  • the present invention aims to remedy the drawbacks of the prior art, by providing the user with a dispensing assembly for a liquid of simple construction, the dispensing head of which is fixed and which includes a precompression pump, small footprint and a reduced number of parts, and therefore, from an industrial point of view, is easy to assemble.
  • the pressure drop has been minimized compared to the pumps according to EP-A 0 437 131 and FR-A-2 634 825, so that the spraying quality is improved. This results in a reduction in the particle size of the liquid leaving the nozzle.
  • the present invention relates to a precompression pump for spraying a liquid under constant pressure, of the type described by FR-A-2 634 825 not comprising a valve between the pumping chamber and the compression chamber. It is characterized in that the precompression chamber is an extension of the pumping chamber, and that the liquid contained in the pumping chamber directly accesses the precompression chamber, upon actuation of the operating means.
  • a means can be provided causing the evacuation of the air inside the pump body, disposed between the first and the second pistons.
  • this means is a central pin arranged on the upper surface of the second piston, facing the pumping chamber; this pin is capable of coming to bear against the first piston, when the operating member is actuated, that is to say, when the volume of the pumping chamber is at a minimum.
  • a mechanical connection is established between the two pistons, the first pushing the second in a position such that the compressed air in the pump body can escape through the distribution channel.
  • the nozzle is fixed relative to the pump body.
  • This spray nozzle is provided with an oriented spray orifice, along an axis substantially orthogonal to the axis of symmetry which defines the precompression chamber.
  • the sliding means for placing in communication and for closing this pump consists, according to a first embodiment, by a first annular lip, integral with the second piston. In the pump rest position, this lip therefore closes the communication between the precompression chamber and the distribution channel.
  • the pump is actuated, by pushing the operating member against the first elastic return means, the pressure of the liquid which is inside the pump body will rise to a predetermined value and cause this communication, by pushing the precompression member against the second elastic return means. It is clear that the predetermined value of precompression depends on the force developed by this second elastic return means.
  • a means for bringing it to atmospheric pressure can be provided, constituted, for example, by an air intake orifice pierced in the wall of the pump body, opening into the lower part of the precompression chamber, this is ie in the part where the second elastic return means is arranged, in order to balance the pressure prevailing in the tank with the external pressure.
  • a sealing means can be arranged between the air intake orifice and the reservoir, closing this orifice during storage and capable of admitting a dose of air into the reservoir during the dispensing of a respective dose of liquid.
  • an orifice is provided between the precompression chamber and the tank.
  • this central orifice is extended by a cylindrical extension crossed by a capillary channel.
  • the capillary channel has the function of preventing the liquid from the reservoir from entering the lower part of the precompression chamber, on the side of the second return means. This arrangement is all the more useful if the liquid to be dispensed is a composition capable of drying or clogging the precompression piston, such as, for example, a hair spray or a paint.
  • this sealing means can be a second annular lip carried by the precompression piston which is arranged inside the precompression chamber. This second lip is placed at a level located between the first lip and the reservoir.
  • the precompression chamber is provided with at least one longitudinal rib, located in an area between the second sealing lip, when it is in the rest position, and a bottom, which separates the precompression chamber from the tank.
  • the second sealing lip of the precompression piston is spaced from the inner wall of the precompression chamber, and air coming from the air intake orifice can penetrate , via the orifice between the bottom of the precompression chamber and the tank, in order to replace with air, an equivalent volume of a dose of liquid dispensed.
  • the means for bringing it to atmospheric pressure may consist of a chimney carried by the precompression piston and extending the latter towards the reservoir and passing through a communication in the bottom of the precompression chamber.
  • the end of the chimney emerging in the tank is provided with a flared cylindrical rod, of a larger diameter than that of the communication.
  • this rod Under the thrust of the second return means on the precompression piston, in the rest position, this rod is able to close the communication between the tank and the lower part of the precompression chamber, on the side of the second return means.
  • the precompression piston will move towards the tank, and thus move the rod away from the walls of the communication, so that a passage is established between the air intake orifice and The reservoir.
  • the sliding means for placing in communication and for closing the pump can be constituted by a pin formed at one end of the second piston which is opposite the first piston. This pin is capable of closing off an extension of the distribution channel parallel to the axis defining the precompression chamber.
  • the first elastic return means housed in the pumping chamber, consists of a helical spring, preferably made of metal.
  • the second elastic return means also consists of a metal helical spring.
  • the non-return valve which prevents the liquid accumulated in the pumping chamber from going back down into the tank, is preferably constituted by a spherical ball housed in a frustoconical portion of the supply channel. Via a dip tube this channel communicates with the liquid contained in a reservoir.
  • This pump can be used for spraying many liquids, such as, for example, a cosmetic composition, in particular a hair spray, a body deodorant, a dermatological lotion, or a pharmaceutical composition ...
  • the invention also relates to an assembly for dispensing a liquid, in the form of droplets, comprising the reservoir for the liquid to be dispensed, surmounted by a precompression pump conforming to the characteristics which have just been described.
  • a means of fixing the pump to the reservoir containing the liquid to be sprayed can be provided.
  • This fixing means comprises, for example, a disc-shaped element, extending radially to the pump body and comprising a peripheral part shaped as a cylindrical skirt, provided inside a snap-fitting bead, able to cooperate with an additional annular groove, produced on a neck with which the reservoir is provided.
  • the reservoir may, in addition, include a covering hood, fixed to the reservoir; this cover surrounding the pump mounted on this tank.
  • the operating member of the pump is actuated by means of a lever arm, articulated on a wall of the covering hood.
  • This arrangement allows the user to spray the liquid in good conditions, precisely, while making, upon actuation, a lower effort than that required for the pump of the prior art.
  • the pump 1 comprises a body 3, generally cylindrical, intended to be fixed to the neck 25 of the reservoir.
  • the fixing is carried out by a snap ring 16, consisting of a cylindrical skirt 16a, carrying inside an annular rib 16b, able to cooperate with the bead 26 of the neck.

  • the user must first prime the pump, that is to say fill the body 3 with liquid, this operation expelling air. For this, it must press once or twice on the operating member 6. During this operation, the air enclosed in the body 3 is compressed. In the low position, the surface 6b of the operating member 6 bears against the spike 10d of the second piston 10, from which it results in a descent of the latter, thus freeing the passage 18 through which the compressed air can escape.

  • the precompression piston 10 descends following actuation of the operating member 6, the lip 10e slides in an area where the ribs 5c are arranged. These ribs then cause the rupture of the seal between the lip 10e and the interior wall of the chamber 5, and the air coming from the orifice 5a can penetrate into the reservoir 24, thus putting it at atmospheric pressure.
