Definitions

  • the present invention relates to a head for dispensing a product, especially liquid or pasty, intended to be mounted on a tank placed under pressure using in particular a propellant, or manually using a pump or a piston.
  • the invention also relates to a set of distribution comprising such a reservoir filled with product, a distribution valve and a dispensing head provided with a push button, actuable by a user in order to cause the ejection of a dose of product.
  • the products likely to be thus distributed from a set of the type mentioned above are in particular cosmetic products, hygiene products and cleaning products.
  • the ejected product travels in a channel ejection to an outlet.
  • the ejection channel does not have the time to empty, so much more product remains large that the outlet is formed in an elongated applicator tip.
  • the aforementioned products are of such a nature that once the distribution is finished, they tend to continue to slowly exit the election channel (overflowing in the case of foam or leakage in the case of liquid or viscous products), which causes soiling on the push button, or in general, on the dispensing head, or even on the user's hand.
  • document FR-A-2 617 809 proposes a set distribution for products having a viscous or pasty consistency, or distributed in the form of foams from a container with a mobile push button provided with an ejection channel.
  • the channel ejection leads into a chamber delimited by a fixed part attached to the container and constituting, with said movable push-button, a dispensing head, the chamber opening to the outside through an outlet, the push button mobile comprising means capable of closing said outlet orifice in position rest of the push button and release it when actuating the latter.
  • the present invention relates to a dispensing head, the construction of which is simplified and whose mounting on a tank is easier compared to the whole according to FR-A-2 617 809.
  • the document EP-A-0 031 123 describes a dispensing head having a channel outlet, the end of which forms an outlet orifice, closed in the rest position by a central shutter.
  • the central shutter and the outlet channel are made in one rigid material, a thin area of the channel being provided at a location away from the outlet, allowing retraction of the channel, and thus the release of the outlet orifice.
  • This device has the disadvantage that the seal between the shutter and the outlet orifice leaves something to be desired, in particular when the outgoing product is an expanding foam. Indeed, because the outlet and the shutter are made by molding in a rigid material, the precision of these parts is insufficient to ensure reliable sealing.
  • the rigid actuating means or semi-rigid are axially movable over a stroke greater than the stroke of the distribution means, the return of the actuating means to the rest position on the one hand by the restoring force exerted by elastic means of the pump or the valve, and on the other hand by the elastic restoring force exerted by means of obturation.

  • a foam such as shaving foam
  • liquid foundation such as foam depilatory
  • foam depilatory such as hair coloring product
  • the actuation means and the distribution means are arranged so that an actuating pressure initially causes the passage of the means for closing the first to second position, then, in a second step, setting communication of the outlet channel with said reservoir, said means for distribution returning from the distribution position to the closed position, under the effect of a restoring force generated by elastic means of the pump or valve.
  • the sealing means ensure, in the second aforementioned position, a seal between the distribution means and the actuation means.
  • the sealing means are formed of an elastomeric material, that is to say of an elastically compressible material in its three dimensions, such as natural or synthetic rubbers.
  • the actuation means have a portion ring surrounding the distribution means and one free end of which is located substantially in the vicinity of the dispensing orifice (s), these sealing means being formed of an annular member mounted inside said annular portion of the actuating means, said means actuators being slidably mounted relative to the distribution means.
  • this annular member defines a skirt of which a free edge ensures, in the second position, the seal between the actuating means and the means of distribution.
  • the actuation means thus that the sealing means are produced by bi-injection of a first and a second physico-chemically compatible thermoplastic material.
  • the first material consists, for example of a polyethylene, or of a polypropylene, which are relatively rigid materials.

  • the outlet (s) open perpendicular to the outlet channel, straight on the internal face of the annular organ.
  • the annular member makes as a jetbreaker, avoiding accidental projections and splashes of product, which is advantageous for the distribution of very liquid products or products subject to strong pressurization.
  • the dispensing head includes a part intended for its fixing to the tank, for example an annular hoop, this part being secured to the actuation means via an articulation zone, for example a film hinge.
  • FIGS. 1 and 2 a perspective view of a distribution assembly is seen. to the invention, generally designated by the reference 1.
  • This set, of axis X is consisting of a reservoir 2 containing a liquid product, in particular foaming and a distribution head 4, mounted on the reservoir using a cylindrical hoop 6.
  • the hoop 6 carries a circular plate 8 in which a cutout is made 10.
  • This cutout 10 delimits a space in which a push button is arranged. 12, articulated pivoting with the plate 8 by means of a film hinge 14.
  • the push button 12 has an actuation surface 13, arranged eccentrically to the X axis and on which the user presses to distribute a dose of product.
  • the push button is provided with a distribution 16, produced in the form of cylindrical tubing, and integral with the actuating surface 13.
  • a distribution 16 produced in the form of cylindrical tubing, and integral with the actuating surface 13.
  • the tip 16 comprises a free end 15, inside which is arranged a sealing means annular 18.
