Definitions

  • the present invention relates to a fluid dispenser member comprising a body intended to be mounted or fixed on a tank opening, a pusher axially displaceable back and forth on the body and a flexible part connecting the body to the pusher.
  • the piece forms return spring means which urge the pusher in the rest position.
  • the piece forms a movable outlet valve member cooperating with an outlet valve seat formed by the pusher.
  • the invention also relates to a fluid dispenser comprising a fluid reservoir and a dispensing member mounted on the reservoir. Such a dispensing member and such a dispenser may in particular be used in the fields of perfumery, cosmetics or even pharmacy.
  • FR-2 674 024 discloses a pump comprising a body integrally formed with a portion of the reservoir.
  • the pump further comprises a pusher movable axially back and forth relative to the body.
  • the pump also comprises an inner part made of a flexible elastic material. This internal part makes the junction between the body and the pusher.
  • the pusher forms an inlet manifold that defines an inlet opening that communicates with the reservoir.
  • This inlet manifold is arranged axially centrally.
  • the pusher comprises a side skirt which extends downwardly from a bearing wall on which it can exert pressure to move the pusher.
  • the peripheral side skirt of the pusher extends in a variable manner around the inlet manifold.
  • the inner part is mounted on the inlet pipe and forms a movable inlet valve member in selective sealing engagement with the inlet opening formed by the pipe.
  • the piece forms return spring means in the form of a tubular sleeve elastically deformable by elongation. This return sleeve extends around the inlet tubing inside the peripheral skirt of the pusher.
  • the inner piece also forms an anchor heel in engagement with the pusher, more particularly at the lower end of the side skirt. The spring sleeve thus connects the anchor heel to the part of the part forming the inlet valve.
  • the inner part forms a deformable annular lip which bears tightly around an outlet valve seat.
  • This annular lip thus fulfills a role of movable outlet valve member for the pressurized fluid within the chamber formed between the pusher and the inner part.
  • the outlet valve movable member lip extends from the anchor heel substantially concentrically around the spring sleeve.
  • the functions of return spring and movable outlet valve member are provided by two separate parts of the inner part. This of course makes the internal part more complicated to manufacture.
  • the present invention aims to overcome the aforementioned drawbacks of the prior art by defining a dispensing member whose flexible inner part is easier to manufacture and assemble.
  • the present invention provides a fluid dispenser member comprising a body for attachment to a reservoir opening, the body defining a fluid inlet communicating the reservoir with the interior of the body, a pusher axially displaceable back and forth on and relative to the body between a rest position and a depressed position, the pusher forming a fluid dispensing orifice, a flexible part connecting the body to the pusher, the piece forming means for return spring urging the pusher in the rest position, the piece forming a movable outlet valve member cooperating with a seat formed by the pusher, the part comprising means for holding in engagement with the body to fix the part on the body , the piece comprising anchoring means engaged with the pusher for securing the piece to the pusher, the holding means being surrounded by the anchoring means, the part comprising an elastically deformable part which extends between the means of holding and the anchoring means, characterized in that the elastically deformable portion forms both the return spring means and the movable outlet valve member.
  • the dispensing member of the present invention has an architecture or design substantially similar to that of the document of the aforementioned prior art, namely that the flexible piece has a diameter less than the level of its connection to the body at the level of its connection to the pusher, which amounts to saying that the holding means are surrounded by the anchoring means, even if the holding means and the anchoring means are axially offset.
  • the movable outlet valve member is deformable radially outwardly from its seat between the rest position and the depressed position.
  • the movable outlet valve member and its seat are of annular shape, the movable outlet valve member surrounding the seat from the outside.
  • the return spring means comprise an inverted dome-shaped annular crown.
  • the deformable portion forms a corolla that extends outwardly around the holding means to the anchoring means, the corolla having in section a siphon shape or gooseneck recumbent.
  • the corolla comprises a first inner section which extends radially outwards by forming an upward curvature and a second outer section connected outside the first section and which extends radially outwards in forming a bend down.
  • the movable outlet valve member is formed at the junction of the first and second sections. We can say that the means of are formed radially inside the first section and the anchoring means are formed radially outside the second section.
  • the part also forms a movable member of the inlet valve biased resiliently by elastic tabs on an inlet valve seat.
  • the flexible part forms both the movable members of the inlet valve and the outlet valve and the return spring means.
  • the invention also relates to a fluid dispenser comprising a fluid reservoir and a dispensing member as defined above.
  • a fluid dispenser is shown which is more particularly suitable for dispensing pasty or viscous products such as creams. Therefore, it is more particularly a cosmetic dispenser.

  • This opening 61 may for example be folded over the neck 51 as seen in the figures.
  • the flexible pouch 6 constitutes a fluid reservoir of volume variable as fluid is removed from the bag.
  • tank associated with the dispensing member of the invention In particular, it is possible to use a reservoir comprising a barrel and a follower piston slidably mounted inside the barrel. This is another tank of the airless type. It is also possible to use more conventional constant volume tanks such as glass, plastic or metal flasks. In this case, the dispensing member of the invention must be provided with a dip tube.

  • This ring 11 can be provided with any appropriate attachment means allowing a firm and preferably definitive fixation of the body 1 on the rigid shell 5, or more generally on the fluid reservoir.
  • This external fixing ring 11 is connected to an inner sleeve 12 which, in its lower part, penetrates inside the neck 51.
  • the sleeve 12 wedges the opening 61 of the flexible bag 6 against the inner wall of the neck 51 of the rigid outer shell 5. The opening 61 can even be wedged between the neck 61 and the outer fixing ring 11.
  • the Internal bushing 12 forms a reentrant thrust profile 121, the function of which will be explained hereinafter.
  • the sleeve 12 is extended by a substantially horizontal annular flange 13 which closes the opening 61 of the pocket 6.
  • This annular flange 13 acts as a roof or shoulder retreating for the fluid reservoir.
  • the flange 13 extends upwards in the form of a substantially cylindrical pipe 14 which terminates in a free upper end.

  • the pusher 2 comprises a bearing surface 21 on which can be pressed with one or more finger (s) of a hand to move it axially back and forth relative to the body 1.
  • the bearing surface 21 extends substantially perpendicular to the axis X.
  • the bearing surface 21 is extended downwardly by a peripheral side skirt 25 whose lower free end defines a bead of stop 251 intended to cooperate with the retaining end profile 121.
  • the skirt 25 has an outer diameter smaller than the internal diameter of the sleeve 12.
  • the pusher 2 forms a dispensing nozzle internally defining an outlet conduit 23 opening at a dispensing orifice 24. The user can collect the fluid dispensed at this dispensing orifice 24.
  • the nozzle extends radially or laterally outwards.
  • the pusher 2 also defines a seat flange 22 which extends downwardly from the bearing surface 21.
  • the seat flange 22 is of substantially cylindrical annular shape whose generator is also confused with the X axis.
  • the seat flange 22 has a diameter smaller than that of the side skirt 25, but greater than the outside diameter of the tubing 14.
  • the pusher 2 is mounted on the body 1 with its skirt 25 engaged inside. of the sleeve 12. The pusher 2 is prevented from disengaging from the body 1 because of the engagement between the bead 251 and the profile 121.
  • the flexible piece 3 is preferably made in one piece.
  • the part 3 comprises a fixing sleeve 33 engaged inside the tubing 14 at its free upper end.
  • the sleeve 33 may be engaged in force inside the tube 14. It is possible, however, to design latching means to assist in the attachment of the sleeve 33 to the tube 14.
