Definitions

  • the present invention relates to the field of dispensers for pasty products, comprising a piston sliding in a sealed manner inside a tubular body going towards a dispensing head, as well as pumping means controlled by an actuator and a valve d expulsion or closure of a distribution or exit passage of the pasty product.
  • pasty product here designates any product which can be distributed by such a distributor, whether it is described as paste, gel or cream.
  • Document FR-A-2557076 describes a dispenser meeting the definition given above, with two embodiments: the first where the bottom piston provided with a non-return metallic skirt moves upward under the effect of the depression caused by the evacuation of the product out of the chamber surmounting this piston, the underside of the piston being at atmospheric pressure and the second where the bottom piston is pulled up step by step, in the direction of the orifice outlet, during successive uses of the dispenser, by a connecting rod coupled to the actuating lever so that the piston rises along the rod each time the latter is depressed.
  • the Applicant has found that the effort for dispensing the pasty product (effort to be exerted on the actuator support veil) was too high: 2.5 kg instead of less than 1.5 kg desirable, in this case with a return time to the initial position or cycle time of 2 to 3 seconds, which is acceptable in itself.
  • the Applicant has sought to develop a means for reducing the expulsion effort, and secondarily a means for reducing the return time or cycle time of the distributor.
  • said upper end of the upper tube of the deformable pumping element consists of an annular end edge and said expulsion valve comprises a flexible disc whose periphery is held in abutment on said end edge of the tubing by a central support means of this disc, this support means being linked to said actuator, said flexible disc and said end edge of the tubing thus constituting respectively the valve and the seat of said expulsion valve .
  • the new expulsion valve there is a direct passage of the pasty product between the upper end edge of the pumping element and the periphery of the flexible disc forming a valve, and the height of the peripheral gap of passage obtained for a given expulsion force is a function of the thickness of the flexible disc and of the flexibility of the material of this disc, which makes it possible to modify the opening force or the width of this passage interval, by changing this material and / or by changing this thickness.
  • the central support means of the flexible disc is advantageously a longitudinal rod supported by its lower end on the disc or linked to this disc, the top of this rod being held by a centering means carried by the actuator, by example a small tube from the underside of the actuator veil in which the top of the rod is embedded or reliefs of the same function.
  • the flexible disc and its longitudinal support rod are in one piece with the tubular pumping element, typically forming a molded part in a single operation, and the flexible disc is then connected to it.
  • the interior of the upper tube by flexible connecting means, for example flexible rods succeeding a short central rod carried by the underside of the disc.
  • the arrangement of the flexible connection means is such that the periphery of the flexible disc can be kept in sealed contact with the pasty product on the end edge of its upper tube, acting on its longitudinal support rod.
  • the tubular pumping element is in its various presentations preferably in one of the materials of the group formed by: thermoplastic polymers, silicone resins, natural rubber and synthetic rubbers.
  • the flexible disk has, outside its central zone carrying the longitudinal support rod and, below, a means of connection to the upper tube, a thickness typically between 0.15 and 0.45 mm.
  • the new expulsion valve of the dispenser of the invention has been associated with a suction valve described in a French patent application FR-A-2604904 published on 15.04.1988.
  • the tubular body of the dispenser then has a top carrying a passage orifice surrounded by an annular surface constituting the seat of a suction valve for the pasty product in the compression chamber which is delimited by the tubular pumping element, the valve of this valve consisting of an upper web, the annular rim of which is applied in a sealed manner on said annular surface in the closed position of the valve, and an underlying portion engaged in said passage orifice and provided at its lower part with one or more retaining reliefs of overall diameter greater than 0.4 to 2 mm in diameter of said passage orifice.
  • the new valve developed, facilitating the suction of the pasty product in the compression chamber, has a surprising influence on the return time or cycle time, as will be seen in the tests.
  • the underlying portion of the valve of this new suction valve differs from the corresponding portion of the previous valve in one fundamental point: it has spaced reliefs whose longitudinal outer edges serve as means of guiding the valve in the orifice passage of the top of the tubular body, these reliefs allowing the passage between them of the pasty product, and the overall diameter of these reliefs being 0.3 to 1.5 mm less than the diameter of said passage orifice.
  • the passage of the pasty product through the valve is then multi-radial, whereas in the precise case of the previous valve the product can only pass around the underlying cylindrical portion of the valve, between this portion and the orifice of passage.
  • the means for retaining the underlying portion of the valve of the invention preferably consist, in particular for molding, of a substantially circular rod carried by the lower part of the outer edges of the spaced reliefs.
  • the upper veil of the valve then comprises a hollow central zone, the underside of this central zone being substantially halfway up the windows for the passage of the pasty product through the valve delimited by the annular edge of the veil of the valve, the spaced reliefs and the circular retaining ring.
  • the retaining ring preferably has an outside diameter greater than 0.5 to 1 mm than the diameter of the passage orifice of the top of the tubular body and the longitudinal outer edges of the reliefs spaced from the valve preferably have a smaller overall diameter. from 0.3 to 0.8 mm at this diameter of the passage opening.
  • the suction valve As described for the suction valve of EP-A-02130248, the suction valve which has just been described can be injected at the same time as the top of the tubular body on the skirt of this tubular body, the circular rod of the valve being connected to the orifier of the top by a breakable crown of low thickness. This crown is broken after demolding and the circular rod is forced through the passage orifice.

  • the tubular body preferably comprises means for air leakage during the insertion of said piston into this body until contact with the pasty product contained therein, consisting of a transverse internal relief situated at the bottom of said circular cylindrical skirt and of minimum internal diameter less than 0.3 to 1.5 mm to the inside diameter of said skirt as well as to a flared entry zone of this relief of decreasing inside diameter from an engagement diameter at least equal to the diamet re outside in the free state of said flexible upper lip of the piston up to said minimum inside diameter of said relief, the outside diameter of said middle part of the piston being at least 0.3 mm less than said minimum inside diameter of said relief.
  • the expulsion valve of the invention has a variety of embodiments, in several pieces or in one piece with the tubular pumping element, and it allows adjustments the opening force or the width of the passage interval of this valve.
  • the suction valve which is preferably associated with it makes it possible to surprisingly reduce the time for returning to the rest position of the dispensing head, in particular when the search for a low dispensing force has caused a tubular element to be chosen. low spring effect pumping.

  • a cover 31 can be placed on the dispensing head and is then supported on a rim of the outer skirt 15.
  • the support of the actuator 16 produces: a deformation of the pumping element 13 similar to that of FIG. 5, the closing of the valve 7, as well as a compression of the pasty product contained in the element 13 and its expulsion by passage between the veil 25 and the flexible lip 22, followed by its escape by the outlet duct 27.
  • the second control distributor 32 differs from the first distributor 1 only by its actuator 33.
