  • Such a bellows is relatively bulky and unsightly and requires to provide a dressing skirt extending around him.
  • the patent application FR 2,735,452 discloses an automatic and waterproof push-plug for delivering a liquid or pasty product contained in a tank.
  • This plug-pusher comprises a means acting as a spring consisting of a deformable chamber in the form of a balloon for automatically resetting the plug-push and conferring the seal to the piston of the tank relative to the rest of the plug-push.
  • the invention aims in particular to remedy all or part of the aforementioned drawbacks.
  • a push-button intended for the actuation of a dispensing member
  • this dispensing member comprising a member movable between two positions
  • the push-button comprising a head, defining a surface of support for the user and a dispensing orifice, a base and an elastically deformable portion connecting the head to the base, the head being adapted to be secured to the element
  • this push button being characterized by the fact that the elastically deformable portion is arranged to deform in the direction of a winding on itself when the head is depressed and is adapted to recall by elastic return the movable member in an initial position and the fact that the pushbutton is made in one piece by molding.
  • the elastically deformable portion is deformed in the present invention other than a bellows or a helical spring, since a bellows or a helical spring deforms not in the direction of a winding on itself but in the direction of axial settlement.
  • the push-button according to the invention makes it possible to avoid the use of a metal spring to return the pump to its initial configuration after dispensing a dose of product, without presenting the aforementioned drawbacks of the patent.
  • US-A-5,363,993 is a metal spring to return the pump to its initial configuration after dispensing a dose of product.
  • the pushbutton according to the invention can also be manufactured easily by plastic molding and can be made with an aesthetic shape, to overcome a dressing skirt surrounding the elastically deformable portion.
  • the elastically deformable portion has a general dome shape.
  • the head is in the center of the elastically deformable portion.
  • Such a configuration makes it possible to promote translational movement of the head when the user presses on the latter.
  • the elastically deformable portion is arranged to form a fold when the head is depressed, and at least from a certain driving stroke of the head, the connection zone of the latter to the elastically deformable portion passes to- below the level of the top of the fold.
  • the elastically deformable portion has a substantially constant thickness.
  • the elastically deformable portion is devoid of folds at rest.
  • the base of the push button has a tubular shape, preferably symmetrical of revolution.
  • the head comprises a tip for attachment to a control rod of a pump.
  • the tip may extend below the level of the connection zone of the elastically deformable portion on the head.
  • the head comprises a housing allowing the fixing a nozzle.
  • the axis of the nozzle may be perpendicular to the direction of depression of the head to dispense a dose of product, or alternatively to have another orientation.
  • the elastically deformable portion connects to the head substantially perpendicular to the direction of depression of the head to dispense a dose of product.
  • Such a configuration makes it possible to cause the elastically deformable portion to wind on itself from the beginning of the driving stroke of the head.
  • the elastically deformable portion connects to the head by a zone of reduced thickness.
  • Such a zone of reduced thickness facilitates translational movement of the head when it is depressed.
  • the base is arranged to engage on the pump body and preferably comprises in this case, at the area for fixing on the pump body, an annular bead.
  • Such bead provides a greater clamping force to keep in place the push button on the pump body.
  • the thickness of the elastically deformable portion may be between 1 and 3 mm for example, being preferably close to 2 mm.
  • the head of the push button has an enlarged upper end.
  • the push button is made in one piece by molding.
  • the plastic material used to mold the push button may be a shape memory material, preferably chosen from mixtures based on the following materials: ethylene vinyl acetate, thermoplastic elastomers and low density polyethylene.
  • a container 1 known in itself provided with a pump 2 provided with a push button 3 according to the invention.
  • the container 1 is filled with a liquid or pasty product P, in contact with the body of the container itself in the example described.
  • Product P could, in a variant not shown, be trapped in a pocket that can retract during dispensing.
  • the pump 2 can be with or without air intake.
  • It comprises a pump body 17 and a hollow rod 6 movable in translation along the axis X with respect to the pump body 17, to move downwards to dispense a dose of product.
  • the pump body 17 is fixed in a mounting skirt 4 made at the top of the container 1 and houses, in a conventional manner, a suction valve and a discharge valve, not visible in the drawing, and defines with a piston also not shown in the drawing, integral with the hollow rod 6, a pumping chamber of variable volume.
  • a push-button 3 makes it possible to use a pump body 17 without a spring inside, as will be specified below.
  • the aforementioned discharge valve opens to allow the distribution of the product through the inner channel 8 of the hollow rod 6 when the volume of the pumping chamber decreases, that is to say when the hollow rod 6 goes down, the valve suction is then closed.
  • the pump 2 is connected to a dip tube 9 for using the container head up.
  • the push-button 3 comprises a base 10 fixed on the upper part 11 of the pump body 17, a head 14 and an elastically deformable part 15 connecting the head 14 to the base 10.
  • the head 14 comprises in the lower part a tubular tip 18, of axis X, in which is inserted the upper end of the hollow rod 6, and has in the upper part a housing 20 of axis Y perpendicular to the axis X, for mounting a nozzle 21, the latter may be single port or vortex channels, depending on the nature of the product dispensed and the destination thereof.
  • the interior of the housing 20 communicates with the inside of the nozzle 18 by an inner channel 19 allowing the product exiting the hollow rod 6 to be dispensed.
  • the head 14 has, as can be seen on the figure 2 , an enlarged upper end 25 defining a bearing surface 26 substantially flat and perpendicular to the axis X.
  • the elastically deformable portion 15 is not in contact with the product, has a generally dome shape, the head 14 of the push button 3 is connected to the elastically deformable portion 15 at the top of this dome.
  • the elastically deformable portion 15 connects to the head 14 by a thinned annular zone 30, but also has a substantially constant thickness between this thinned zone 30 and the base 10.
  • the elastically deformable portion 15 When the elastically deformable portion 15 is observed in axial section as on the figure 3 , it has a substantially quarter-circle shape on either side of the head 14.
  • the elastically deformable portion 15 connects to the head 14 in a direction substantially perpendicular to the axis X and is connected to the base 10 parallel to the axis X.
  • the base 10 has a symmetrical shape of revolution, with an annular bead 32 on its radially inner surface, this annular bead 32 being intended to increase the clamping force on the upper part 11 of the body of pump 17.
  • the lower end of the base 10 is beveled on its radially inner surface to facilitate the introduction of the push button 3 on the pump body 17.
  • the outer surface of the elastically deformable portion 15 and the base 10 is continuous and free of relief or recess, which is particularly aesthetic.
