Definitions

  • the present invention relates to a pump for dispensing a product, especially a cosmetic product.
  • the patent US 5,687,884 describes a pump comprising a suction valve formed by a lip of an elastically deformable membrane. This pump also comprises a discharge valve formed by a lip of a closure element located at a dispensing nozzle.
  • a membrane made of an elastomer is mounted on the support.
  • This membrane has a symmetrical central portion of revolution, sleeve-shaped open at its upper end and closed at its lower end.
  • the central duct of the pushbutton is inserted into the membrane until it bears against the bottom of the central part in the form of a sleeve.
  • the membrane constitutes an elastic return member for returning the push button to its initial position after dispensing a dose of product.
  • the membrane by pressing on the central duct isolates the pumping chamber and avoids a return of air therein.
  • the membrane thus plays the role of a discharge valve.
  • the membrane also acts as a suction valve.
  • Such a pump has the advantage of having only a small number of parts and therefore of being relatively inexpensive to manufacture.
  • the present invention aims to improve the reliability of operation of a pump of the type defined above, namely having a support assembly, to subject a container containing a product to be dispensed, a movable member defining with the support assembly a pumping chamber of variable volume and an elastically deformable membrane, secured to one of the support assembly and of the movable member, this membrane being arranged to deform elastically when the movable member is moved relative to the support, the pump further comprising a suction valve element, arranged to oppose the return of product into the container when the volume of the pumping chamber decreases and a discharge valve member arranged to oppose a return of air into the container as the volume of the pumping chamber increases.
  • the pump according to the invention is characterized in that the discharge valve element is formed by means of a shutter member separate from the membrane and in that the membrane is prestressed when the pump is at rest.
  • the membrane can act as a spring without fear of blockage of the movable member; the discharge valve element being distinct from the membrane, the latter is not likely to oppose the departure of the product leaving the pumping chamber.
  • the membrane being prestressed when the pump is at rest, it avoids any play at rest and reduces the risk of product leakage when transporting the pump.
  • the membrane comprises a central part in the form of a sleeve open at one end and closed at the opposite end, a central part against which the movable member bears.
  • the movable member comprises a first and a second movable parts relative to each other, the first part defining with the support assembly the pumping chamber of variable volume, the second part being movable relative to the first part between on the one hand a relative distribution position in which it is able to drive the first part in the direction of a decrease of the volume of the pumping chamber and secondly a relative suction position in which it is capable of driving the first part in the direction of an increase in the volume of the pumping chamber, the shutter member belonging to the second part, the first part comprising a passage for the circulation of the product towards a dispensing nozzle, the shutter member being movable relative to the first part between a relative position of shutter in which it closes said passage and a relative dispensing position in which it stops closing said passage.
  • the shutter member is in its relative closure position when the second portion of the movable member is in its relative suction position and the shutter member is in its relative dispensing position when the second part of the movable member is in its relative distribution position.
  • the shutter member bears on the membrane.
  • the shutter member advantageously bears against the bottom of this central portion.
  • the aforementioned passage is advantageously defined by a chimney engaged inside this central portion.
  • the shutter element advantageously comprises a rod fixed at one end to the second part of the movable member, this rod extending inside the aforementioned chimney and being provided at the opposite end with a needle portion, adapted to apply sealingly on the chimney to seal.
  • At least one of the first and second parts of the movable member comprises a sealing lip adapted to be sealingly applied to the other part during the relative movement of the two parts.
  • the relative movement of the two parts of the movable member can be made without fear of product leakage.
  • this sealing lip is formed on the first part, at one end of the aforementioned passage.
  • the first part of the movable member is snapped into the support assembly.
  • This first part advantageously corresponds to the lower part of a push button comprising two telescopic parts.
  • the support assembly includes an insert on which the membrane is mounted.
  • the membrane comprises a peripheral portion defining a groove for its mounting on the insert.
  • the insert comprises a suction valve made in one piece by molding plastic material.
  • the peripheral portion of the membrane comprises a flexible lip forming a suction valve
  • the support assembly comprising one or more openings allowing the product to reach the pumping chamber when the volume thereof increases, this or these openings being closed by the flexible lip when the volume of the pumping chamber decreases.

  • tubular skirt 12a has, substantially at mid-height, an annular groove 22 formed on its radially inner surface.
  • This groove 22 is delimited below by an annular bead 23 and superiorly by a shoulder 24, which is located at the lower end of a ramp 25 inclined inwards and downwards.
  • the insert 30 has a tubular wall 31, of axis X, forcibly engaged at its lower end in the cylindrical wall 19.
  • the tubular wall 31 is divided in two, at its upper end, to form firstly on the radially outer side a sealing lip 32 and secondly on the side radially inner an extension 33, which is traversed at several locations of its periphery by openings 34 whose function will be explained later.
  • Longitudinal channels 35 are formed on the radially inner surface of the tubular wall 31 to the openings 34.
  • the extension 33 serves to attach a membrane 40 made of an elastomeric material, for example a nitrile or silicone elastomer.
  • This membrane 40 has a central portion in the form of a sleeve 41 and a flexible annular lip 42 at its upper part, this annular lip 42 surrounding the central portion in the form of a sleeve 41 and connected to the upper end thereof by a transverse wall 43 resting on the upper end edge of the extension 33 above.
  • the central part of the membrane 40 is closed by a bottom 45.
  • the height of the annular lip 42 is greater than that of the openings 34 and the annular lip 42 is arranged to apply, at rest, in a sealed manner on the radially outer surface of the extension 33, so as to prevent a return of product to the container R through the openings 34, as will be explained later.
  • the pump 10 comprises, in addition to the static assembly 11 which has just been described, a mobile assembly forming a push-button 50, comprising a lower part 51 partially engaged in the support 12 and an upper part 52 movable relative to the lower part 51 .

  • This mounting skirt 53 has a radially inner surface 54 cylindrical in revolution about the axis X, on which the annular sealing lip 32 of the insert 30 is sealingly applied.
  • the mounting skirt 53 further comprises, on its radially outer surface, teeth 56 arranged to snap into the annular groove 22 of the support 12.
  • the lower end 57 of the mounting skirt 53 has an annular lip arranged to seal on the annular boss 23 when the teeth 56 rest against the shoulder 24, as shown in FIG. figure 1 .
  • the lower part 51 has, above the mounting skirt 53, a collar 60.
  • This neck 60 has, on its radially outer surface, an annular groove 61 which serves to hook the upper portion 52 of the push button.
  • the upper part 52 comprises a mounting skirt 63 provided at its lower end with an annular bead 64 arranged to snap into the groove 61 mentioned above.
  • the neck 60 forms with the mounting skirt 53 a shoulder 65 on which the upper portion 52 can bear.
  • the lower portion 51 has a transverse wall 66 which connects to the inner surface of the neck 60 above the annular groove 61.
  • This transverse wall 66 supports an annular lip 67 directed downwards and an annular lip 68 directed upwards, whose functions will be specified below.
  • the upper part 52 has an inner skirt 70 whose radially inner surface has a shoulder 73 at its lower end, this shoulder 73 defining axially a cylindrical surface 71 of revolution, on which the annular lip 68 is sealingly applied at its end. higher.
  • a cylindrical housing 74 is formed in the center of the inner skirt 70 to receive a shutter member 80 which will be described later.
  • the upper part 52 has a dispensing nozzle 77 communicating with the space defined by the inner skirt 70.
  • the annular lips 67 and 68 define a passage 90 allowing the product from the container to reach the dispensing tip 77.
  • the obturator element 80 has in the upper part a rod 81 fixed in the housing 74 and, in the lower part, an internally recessed portion 82 connected to the rod 81, forming a shoulder 83.
  • This shoulder 83 is arranged to bear against the lower end of the annular lip 67 when the pump is at rest, as shown in FIG. figure 1 .
  • the shutter member 80 then rests at its lower end 86 against the bottom 45 of the central portion 41 of the membrane 40.
