Definitions

  • the present invention relates to a pump intended to be fixed on a container for dispensing a product contained therein.
  • a pump comprising a body of pump intended to be fixed on a container and comprising at least one vent allowing an air intake, a push button movable relative to the pump body between a low position and high position, a ball suction valve, a piston defining with the pump body a pumping chamber of variable volume and a distribution by which the pumping chamber can communicate with a orifice distribution.
  • the piston is made in one piece with the push button, by molding matter.
  • the push button can be screwed into the pump body in the low position for storage. The tightness of the pump is then obtained by pressing the push button against a conical surface of the pump body.
  • Such a pump is relatively complex and difficult to achieve.
  • the subject of the invention is in particular a pump corresponding to all or part of those needs.
  • the pump comprises a pump body intended to be fixed on a container and comprising at least one vent allowing an air intake, a push button movable relative to the pump body between a low position and a high position, a suction valve comprising a shutter member, a piston defining with the pump body a pumping chamber of variable volume and a conduit through which the pumping chamber can communicate with an orifice distribution.
  • the push button comprises a sealing skirt surrounding the duct of at least part of its height distribution, this sealing skirt being able to apply sealingly to the pump body when the pump is in the low position, to isolate the vent from the outside and the distribution duct is formed by an element attached to the push button.
  • the pump can be manufactured relatively easily, does not requiring no complex shaped part.
  • the piston is constituted by an attached element.
  • the sealing skirt is made in one piece with the pushbutton.
  • the piston is advantageously arranged to isolate the vent when the push button is in its up position.
  • the piston preferably comprises two sealing lips annular, suitable to be applied respectively above and below the vent when the push button is in its high position.
  • the distribution duct is able to bear against the shutter member of the suction valve when the push button is in its low position.
  • the suction valve is kept closed, which reduces the risk of leaks during transport.
  • the pump advantageously includes a spring arranged in the pumping so as to exert on the push button a restoring force bringing it back in its high position.
  • the shutter member of the suction valve can be constituted by example by a ball retained in a cage made in one piece with the body of pump, this cage comprising at least one elastically deformable retention member capable of deforming when the ball is put in place.
  • the distribution conduit is made in one piece with the piston and is stationary relative to the latter.
  • the pump advantageously includes a discharge valve. comprising a shutter member, retained in a housing made in the distribution duct.
  • Such a shutter member can be constituted for example by a ball.
  • the housing receiving the shutter member of the discharge valve can be located in the upper part of the distribution duct.
  • the shutter member of the discharge valve can be returned against a seat formed in the distribution duct by a spring bearing against the pushbutton.
  • the shutter member of the discharge valve may still be free in his home.
  • the push button advantageously forms an upper seat for the shutter member of the discharge valve, the latter coming to bear against this upper seat in the event of the container overturning, vacuum on the outside of the pump or of too rapid product exit.
  • the distribution duct forms a lower seat against which the member shutter forming the discharge valve can come to bear when a vacuum is created in the pumping chamber, during normal pump operation.
  • the housing receiving the shutter member of the discharge valve can still be located in the lower part of the distribution duct.
  • the conduit distribution has a product inlet orifice opening laterally and the piston is movable relative to the distribution duct between a closed position in which it closes the inlet orifice and a dispensing position in which it leaves the inlet open.
  • the distribution duct has an upper stop capable of to limit the upward movement of the piston relative to the distribution duct and a lower stop capable of limiting the downward movement of the piston relative to the distribution duct and one of the stops is arranged so that it can be crossed by the piston when the latter is placed on the distribution duct.
  • It can be for example the upper stop, which is then able to be crossed by the piston when the latter is moved towards the lower stop during of its installation on the distribution duct.
  • the pump body is made in one piece with a skirt of mounting allowing its fixing on the container.
  • the pump body comprises a first member for retainer and the push button a second retainer capable of cooperating with the first to keep the push button in its low position during storage.

  • the material ring 46 is provided with a first locking member 47 and the locking skirt 7 comprises a second locking member 48 able to cooperate with it when the push button 3 is in its low position, as illustrated on Figure 3.
  • the first locking member 47 is constituted, in the example of embodiment described, by a hook directed towards the X axis and the second locking member 48 by a rim directed towards the outside, capable of being brought under the aforementioned hook by a rotary movement of the push button 3 relative to the pump body 2.
  • the first and second organs of locking consist of complementary threads.
  • the distribution duct 10 has an extension 49 at the bottom extending downward along the X axis and able to bear against the ball 17 when the push button 3 is in the low position, as illustrated in Figure 3.
  • pump 1 The operation of pump 1 is as follows.
