Definitions

  • the present invention relates to a liquid or pasty product dispenser usable in particular in cosmetics.
  • Distributors are already known which include a reservoir which contains the liquid or pasty product to be dispensed and a variable volume chamber constituted for example by a cylinder and a piston, the reservoir being connected by a first valve to the variable volume chamber, which opens to the outside of the dispenser by a second valve so that by varying the volume of the variable-volume chamber using a pusher, a pumping action is applied which passes the liquid or pasty product from the reservoir into the variable volume chamber, then outside the dispenser.
  • This opening is also a source of non-sealing for the device.
  • the present invention aims by simple and effective means to remedy the aforementioned drawbacks by ensuring immobilization of the pusher which causes the expulsion of the product.
  • the present invention relates to a liquid or pasty product dispenser usable in particular in cosmetics of the type comprising a retractable reservoir for the product to be dispensed, this reservoir being connected by a first valve to a chamber with variable volume under the action of a pusher, said variable-volume chamber being itself connected to the outside by a second valve, dispenser characterized in that the body of the pusher constitutes with a fixed piston integral with the reservoir the variable volume chamber, the body of the pusher consisting of two concentric parts each provided with an orifice which can pivot one relative to the other between a first position in which the orifices of the two parts of the pusher are opposite one another and a second position in which said orifices are not opposite each other so that the product contained in the variable volume chamber cannot be evacuated through the second external valve and the pusher is thus immobilized.
  • stops are provided on the two parts of the pusher which pivot relative to each other to limit their rotation between the positions for which the channel opening onto the external valve is open or closed.
  • the orifices communicating with the two parts of the pusher are located in the vicinity of the place where the variable volume chamber communicates with the second valve which opens to the outside.
  • variable volume chamber is constituted by a fixed piston provided with the first valve on which slides a movable cylinder incorporated in the lower part of the pusher which is pushed back by a spring arranged around the cylinder mobile and fixed piston in a cavity at the top of the tank.
  • the spring is obtained directly by molding plastic material at the same time as the lower part of the pusher with which it is integral.
  • the valve of the piston can be constituted by two lips which come to apply spontaneously one against the other or by a shutter resiliently pushed back to come to engage in an orifice of the piston.
  • FIG. 1 shows a flexible tank 1 provided with a plug 2 whose periphery clicks at 3 on the upper part of a rigid container 4 which surrounds the flexible tank 1.
  • the upper part of the flexible tank 1 is welded or glued at 6 to the external periphery of the plug 2. After having been filled with its lower end with product 5 to be dispensed, the flexible tank 1 is welded at 1 a .
  • the reservoir 1 has the advantage of being able to deform as the product it contains is dispensed, so that it is not necessary to provide an orifice for its venting.
  • the plug 2 comprises axially a tube 7 which is provided at its upper part with a piston 8 with a central orifice forming a first valve 9 which is closed in the rest state.
  • a pusher 10 comprises a lower part 10b constituted by a cylinder 11 provided with a flange 12 and a skirt 13 whose periphery slides inside the annular recess which is delimited by the internal wall of the plug 2.
  • the boss 15 can easily be engaged below the boss 14 due to the elasticity of the plastic material from which the various parts of the dispenser are made.
  • the plug 2 is extended at its lower part in the axis of the tube 7 by several bars 17 joined at their lower end by a pierced washer 18.
  • these bars 17 is to maintain the flexible tank 1 during its contraction resulting from the gradual consumption of the product 5 which it contains, by avoiding the formation of pockets in which a part of the product 5 would remain which could not be sucked by the variable-volume chamber 19 located inside the push-button 10.
  • the presence of the bars 17 ensures, whatever the filling state of the reservoir 1, the existence of an axial channel through which the product 5 can flow to the variable volume chamber. 19.
  • the upper edge of the cylindrical part 11 of the push-button 10 has a lateral orifice 20.
  • the upper part 10a of the push button 10 includes a first outer cylindrical skirt 22 having a circular rib 23 comes to click into a corresponding recess of the cylindrical wall 11 of the lower part 10 b of the pusher 10.
  • the upper part 10 a of the pusher 10 also includes a second internal cylindrical skirt 24 situated on the other side of the cylindrical wall 11.
  • the skirt 24 has an orifice 25 which, as shown in FIG. 1, can be brought into coincidence with the orifice 20 of the cylindrical wall 11, by pivoting the upper part 10 a of the pusher relative to its lower part 10 b .
  • FIG 2 a perspective view of the upper part 10 partially cut and the lower portion 10b of the pusher 10.
  • Stops not shown make it possible to limit the angular pivoting of the upper part 10 a with respect to the lower part 10 b of the pusher so that in one position the orifices 20 and 25 are in correspondence while in the other position, they are not.
  • the skirt 13 of the lower part 10b has, as can be seen in FIG. 2, an oval contour which corresponds to the general shape of the rigid container 4.
  • This oval shape has the advantage to avoid that the lower part 10 b of the pusher 10 is rotated upon movement of the upper part 10 a which provides easy switching of the position where the orifices 20 and 25 are in correspondence to the position where they are not and vice versa.
  • the spring 16 pushes the latter upwards, creating a depression inside the chamber 19 which sucks the product 5 inside the tank 1 inside.
  • the skirt 22 is not liable to detach from the cylinder 11 in the event of accidental pushing on the pusher 10 because the groove 23 is isolated from the channel 26.
  • the zone serving to retain the pivoting part of the pusher on the other part serving as support is isolated, when the orifices 20 and 25 are no longer in communication, from the product located inside the part serving as support.
  • FIG. 3 and 4 There is shown in Figures 3 and 4 a second embodiment of the invention in which there is the plug 2 placed on the upper part of the container, which receives the pusher 10 consisting of a lower part 10 b consisting of a cylinder 11 provided with a flange 12 carrying a skirt 13.
  • the pusher 10 consisting of a lower part 10 b consisting of a cylinder 11 provided with a flange 12 carrying a skirt 13.
  • the spring 16 which pushes the pusher upwards constitutes a single piece with the skirt 13, which comes during the molding of the plastic material.
  • valve of the fixed piston 8 is constituted by a stud 9 surrounded on its periphery by orifices 9 a to allow the product contained in the tank to pass, the stud 9 bearing elastically against the orifice 9b made in the upper part of the tube 7 which is integral with the plug 2.
  • the vacuum which is created in the chamber 19 causes the raising of the stud 9, which allows the product contained in the reservoir to flow through the orifices 9 b and 9 a to reach the chamber 19 from which it is expelled when the pusher 10 is lowered again by flowing through the channels 25 and 26 as was previously described for the first embodiment.
  • FIG. 4 schematically shows how the internal tubular part 11 of the pusher 10 comprises on approximately a quarter of its periphery two stops 11 a and 11 b delimiting a recess 11 c .
  • FIG 4 how the upper part 10a of the pusher includes within its cylindrical wall 22 has a rib 22 which cooperates with the stops 11a and 11b for limiting the rotation of the upper part 10a of the pusher between a position shown in Figure 3 in which the orifices 20, 25 and 26 are in correspondence and another position not shown for which the upper part of the tube 11 does not have an opening 20 and therefore closes the passage between the openings 25 and 26, which prevents any outward flow of the product contained in the volume 19 even if the pusher 10 is pressed.
  • the dispenser according to the invention is of a particularly simple and economical construction while offering perfect security with regard to unwanted product flows to the outside.
  • the general structure of the dispenser according to the invention allows easy production of the various parts which are simple in shape and in reduced number by plastic molding.
  • the flexible tank 1 can be replaced by a follower piston tank whose useful volume gradually decreases as a function of the consumption of the product.
