Definitions

  • the present invention relates to a fluid dispenser member generally intended to be associated with a fluid reservoir to form together a fluid dispenser. It is a dispensing member whose actuation is usually performed manually using a finger of the user.
  • the fluid product is distributed in the form of a jet of fine sprayed droplets, a continuous net or a dab of fluid, particularly in the case of viscous product, such as cosmetic creams.
  • Such a fluid dispenser member may in particular be used in the fields of perfumery, cosmetics or even pharmacy to dispense more or less viscous products.
  • the present invention is more particularly, but not exclusively, concerned with a type of dispensing member which is commonly referred to as a "push-pump".
  • a type of dispensing member which is commonly referred to as a "push-pump".
  • the dispensing member comprises a pusher forming not only a dispensing orifice but also defining a portion of a fluid product chamber in which fluid is selectively pressurized.
  • a pump it is a pump chamber.
  • a peculiarity of this pusher pump lies in the fact that an inner surface of the pusher, of generally cylindrical general shape, serves as a sealed sliding shaft for a piston which moves in sealed contact in this barrel to thus selectively unmask the orifice of distribution.
  • This piston is generally a piston of the differential type that moves in response to a pressure variation of the fluid within the chamber.
  • This differential piston is to be differentiated from the main piston whose displacement is generated by the actuation of the pusher.
  • a differential piston and a main piston movable in sealing contact in respective drums.
  • the main drum for the main piston can also be formed by the pusher.
  • the pusher comprises a bearing wall on which is exerted a pressure with a finger to actuate the pusher.
  • the pusher comprises a skirt that extends downwardly from the support wall. This skirt forms a first sealed sliding shaft for a differential piston and a second main shaft for the main piston of the pump.
  • the differential piston is dissociated from the main piston.
  • the differential piston is biased away from the support wall by a spring which acts as both a return spring and a precompression spring.
  • the sliding piston of the differential piston is formed with an outlet conduit which leads to a nozzle attached in a housing formed in the skirt of the pusher.
  • This nozzle forms a dispensing orifice at which the fluid product exits the dispensing member.
  • the housing formed by the skirt is made with a swirl system that cooperates with the nozzle to drive the fluid in a swirling motion before exiting through the dispensing orifice.
  • This vortex system is conventionally formed by one or more tangential swirl channels opening into a vortex chamber centered precisely on the dispensing orifice.
  • the swirl system is in the form of a recess network within the skirt housing. This recess network is then supplemented by the attached nozzle which isolates the swirl channels and the chamber.
  • the sliding shaft of the differential piston is in the form of a cylindrical surface only interrupted at the outlet channel.
  • the pump of the document WO 97/23304 consists of five essential components, namely a body intended to be associated with a fluid reservoir, the pusher, a ball forming an inlet valve, the differential piston and the nozzle.
  • the body forms the main piston.
  • the purpose of the present is to simplify a distribution member of the type described in the aforementioned prior art document so as to reduce the number of component parts.
  • a particular goal is to do without a reported nozzle.
  • Another aim is to preserve the swirl system which contributes to the quality of the distribution of the fluid product.
  • Another object of the invention is to improve the cooperation between the differential piston and the pusher, in particular the sealed sliding contact and the creation of the outlet passage for the fluid product.
  • the present invention provides a fluid dispenser member according to claim 1.
  • This type of dispensing member may be a pump-type push-button, but it may also be other types of dispensing members in which the pusher is dissociated from the distribution wall.
  • the distribution wall is fixed relative to the reservoir, or mobile relative to the pusher.
  • the sliding shaft, the dispensing orifice and the swirling system are integrally formed by the distribution wall.
  • the internal surface forms a fluid swirling system immediately upstream of the dispensing orifice. Sliding the lip on a section offset from the section where the dispensing orifice is formed is particularly advantageous with respect to the molding of the dispensing wall.
  • the distribution wall is very generally made from molded injected plastic material.
  • a mold consisting of several elements is used. One of these elements forms in particular a pin intended to form the internal surface of the distribution wall. In the case of the present invention, this pin must form the swirl system. Since the swirl system extends into a recessed portion in the slide shaft, the pin must form a corresponding recess protruding outwardly.
  • the protruding footprint must be removed in force.
  • the protruding imprint must therefore leave the recessed portion that it has formed and move over an axial extent of the sliding shaft. Since the plastic is flowable, the passage of force of the protruding imprint marks very little sliding shaft.
  • the projecting indentation of the pin can be removed at this level without biting into the inner surface of the guide wall. As a result, the projecting indentation of the spindle is only forcibly withdrawn over a small axial extent of the sliding barrel: this limits the risk of deterioration of the sliding barrel during demolding of the spindle.
  • the present invention is not limited to the case where the distribution wall forms a swirl system.
  • the piston comprises a second lip in sealing contact with the upper section.
  • the piston is out of contact with the upper section. In this case, there is no upper lip.
  • the piston comprises a sealing abutment edge in sealing abutment contact against an abutment surface, the piston being resiliently biased against this sealing abutment surface in the rest position, the sealing contact between the abutment edge and the abutment surface hermetically isolating the chamber from the dispensing orifice.
  • the abutment surface is frustoconical and urges the abutment edge radially outwards.
  • the distribution wall is formed by a pusher further comprising a bearing wall which extends on its outer periphery by the distribution wall, the abutment surface being formed by the support wall.
  • the transition section is frustoconical.
  • the distribution wall is formed by a substantially cylindrical skirt further comprising a guide wall defining an inner surface which advantageously extends substantially in the extension of the lower section, the guide wall comprising internal hooking means in abutment with external holding means.
  • the guide wall of the pusher surrounds the portion of the body forming the holding means.
  • the sealing lip in contact with the lower section is urged elastically towards the upper section in the rest position.
  • the abutment edge can be implemented without the lower lip sliding on a lower section of larger diameter.
  • An interesting aspect of the invention lies in the fact that the same wall through which a dispensing orifice passes internally forms a fluid swirling system.

  • the body 651 is provided at its upper end with an opening in the form of a neck 653, which serves to fix the dispensing member of the invention.
  • the dispensing member 600 comprises three constituent elements, namely a body 610, a pusher 620 and a piston member 630.
  • the dispensing member further comprises spring means 640, here in the form of a spring. black pudding.

  • the pusher By exerting a force on the outer bearing surface 6211 of the bearing wall, the pusher moves axially relative to the body. Since the piston member abuts against the bearing wall, the piston member is pushed by the pusher. Initially, the movement of the pusher has the effect of closing the inlet valve: the axial rod 637 engages more deeply in the sleeve 616 until a sliding sealing contact is created between the sleeve or the rod. Thus, the pump chamber 1 is isolated from the tank 5. From this moment, the product in the pump chamber 1 is to be put under pressure. Since the fluid product is incompressible, the total useful volume of the pump chamber must remain constant.

  • the lower lip 633 slides against the lower surface section, which can not have been damaged by the removal of the molding pin which served to form the swirl system, because its inner diameter is greater than to that of the spit.
  • An interesting feature of the invention lies in the fact that the piston member 630 is urged against the bearing wall 621 and moves under the effect of the pressure increase inside the pump chamber. away from this support wall. This is made possible thanks to the fluid product passage holes 634 which pass through the plate 631 forming the differential piston. It can also be said that the support wall 621 defines a wall element of the pump chamber.
  • Such displacement of the differential piston away from the bearing wall 621, in combination with a swirl system 626 formed in the distribution wall 623, is advantageous in terms of demolding since the upper lip 632 slides in a sealed manner. on the upper part of the sliding shaft which has not been damaged by the removal of the molding pin forming the negative imprint used to mold the swirl system.
