Definitions

  • the present invention relates to a pump intended to be mounted on a container for dispensing a product contained therein.
  • Such a pump has a relatively large number of parts and its manufacturing is expensive.
  • the invention aims to meet this need.
  • the pusher includes means for retaining the ball made in one piece with the rest of said housing by molding of material plastic.
  • the number of component parts of the pump is reduced, which reduces the cost.
  • said housing is located in a conduit and said retaining means are constituted by the lower end of this conduit, which is shaped to allow the positioning of the ball in said housing by elastic deformation.
  • the pump includes a valve suction device comprising a ball forming a shutter and the lower end of the duct above is arranged to maintain this ball in the closed position when the pusher is in its low position.
  • the pump body includes a vent capable of communicating by a passage with the outside of the container when the pusher is in an intermediate position between its high and low positions, so that allow air to enter the container when the product is drawn into the chamber pumping and the pusher is shaped to isolate said vent from the outside in its high and low positions.
  • the inside of the container does not communicate with the outside except when the pusher is in an intermediate position between its high or low positions, that is to say at the time of use.
  • the product contained in the container therefore remains sheltered from outside air when the pusher is in the low transport position or in the high standby position of use.
  • the pusher has an inner skirt made in one piece and able to slide tightly inside the body of pump.
  • said inner skirt is applied sealed by its lower part on the pump body and the distance between the vent of said lower part when the pusher is in its lower position is lower or equal, preferably substantially equal to the displacement travel of the pusher of its low position towards its high position, so that said lower part isolates the vent from outside when the pusher is in the high position.
  • said inner skirt is applied in a sealed manner by its upper part on the upper end of the pump body when the plunger is in low position.
  • the inner skirt has, between its parts lower and upper, a constriction providing an annular space inside the body of pump, space in which said vent opens when the pusher is in its position low or in an intermediate position between its high and low positions.
  • the pump body is connected to its upper end by an annular bearing to a mounting skirt subject to a neck of the container.
  • This mounting skirt is advantageously extended upward by a cylindrical wall defining a guide for a helical spring working in compression to recall the pusher in the high position.
  • the pump 1 shown in Figure 1 includes a movable pusher 2 which can move vertically along an axis X relative to the fixed part 3, which comprises a mounting skirt 4 secured to the neck 5 of a conventional container 6 and partially represented.
  • the mounting skirt 4 is screwed onto the neck 5 but alternatively it could be fixed otherwise on the latter, by snap-fastening example.
  • the mounting skirt 4 is extended upwards by a cylindrical wall defining a guide 7 for a helical spring 8 of axis X working in compression and also serving as a guide for pusher 2.
  • the guide 7 has at its upper end an annular flange 47 which limits the travel in movement upwards of push-button 2.
  • the spring 8 rests at its lower end against an annular bearing 9 of the fixed part 3.
  • This scope 9 extends radially inwards from the region in which the mounting skirt 4 and the guide 7 meet.
  • the spring 8 comes to bear at its upper end in the bottom 10 of a annular groove 11 of pusher 2.
  • This groove 11 is formed between an inner skirt 12 symmetrical with revolution around the X axis and a coaxial outer skirt 13.
  • Locking means are provided on the facing faces of the skirt 13 and the mounting skirt 4 to allow the pusher 2 to be blocked in its low position shown in Figure 1.
  • This blocking is useful during the transport of the container 6 for example, in order avoid accidental product leakage.
  • the abovementioned locking means comprise, in the exemplary embodiment described, lugs 14 formed on the radially outer surface of the mounting skirt 4 and reliefs 15 located on the radially inner surface of the outer skirt 13.
  • pins 14 and reliefs 15 can cooperate in the manner of a type of attachment. bayonet.
  • the user presses it while the reliefs 15 are angularly offset relative to the pins 14, to bring the first at a level lower than the second, then rotate the pusher 2 around the X axis so as to position the reliefs 15 under the lugs 14.
  • a central duct 16 is made in one piece by molding of material plastic with inner skirt 12.
  • This conduit 16 is centered on the X axis and is connected at its upper end to a lateral duct 17, also made in one piece by plastic molding with the rest of pusher 2.
  • the lateral conduit 17 opens to the outside of the pusher 2 through an orifice outlet 40, which is oriented in a direction Y perpendicular to the axis X.
  • the aforementioned annular bearing 9 is connected to the upper end of a body of tubular pump 18, closed at its lower end by a bottom 19.
  • the bottom 19 serves as a seat for a ball 20 and includes a nozzle 42 intended for the connection of a dip tube 21 extending to the bottom of the container 6 where it opens.
  • the ball 20 constitutes with its seat made on the bottom 19 a valve suction as will be explained below.
  • the lower end of the central duct 16 defines, as can be seen in FIG. 4, a housing 35 in which a ball 22 is retained.
  • the ball 22 constitutes with its seat produced inside the housing 35 a discharge valve, as will be specified below.
  • the lower part 23 of the inner skirt 12 is arranged to slide from sealingly in contact with a cylindrical portion of revolution of the interior surface of the pump body 18.
  • the upper part 24 of the inner skirt 12 is arranged to be applied from sealingly on the upper end of the pump body 18 when the pusher 2 is in the low position, as shown in Figure 1.
  • the upper part 24 is shaped to be inserted with friction in the pump body 18 when the pusher 2 is in the low position.
  • the inner skirt 12 has an annular constriction 46 between its parts lower 23 and upper 24.
  • This constriction 46 defines with the pump body 18 an annular space 25 of which the function will be specified below.
  • a vent 26 opening at the base of the neck 5 is produced in the pump body 18 for communicating the abovementioned annular space 25 with the interior of the container.
  • the pump body 18 is applied sealingly at its end on the inside surface of the neck 5.
  • This duct 16 is internally shouldered at 30 and its internal diameter passes, while this shoulder is crossed by moving downward in the housing 35, from a value d 1 less than the diameter of the ball 22 to a value d 2 slightly greater than the diameter thereof.
  • the internal diameter of the duct 16 is then progressively reduced downwards along a conical surface 31 until a value d 3 is slightly lower than the diameter of the ball 22.
  • the conical surface 31 serves as a seat for the ball 22 and the cylindrical surface of diameter d2 extends above this surface 31 along the axis X over a sufficient height to allow the ball 22 to move away from its seat 31 during the dispensing of the product in order to obtain the desired flow.
  • the central duct 16 ends at its lower end with lugs 32 directed radially inwards and shaped so as to be able to deform elastically radially outward when the ball 22 is introduced from below in housing 35 according to arrow F.
  • Recesses 33 are made on the outside of the tabs 32 at the level of their junction with the rest of the conduit 16 so as to give them the flexibility required for mounting the ball 22.
  • Reliefs 36 are made in the upper part of the housing 35 to prevent that the ball 22 does not close the central duct 16 during the distribution of the product.
  • FIG. 3 shows the fixed part 3 of the pump in isolation.
  • the bottom 19 has a recess conical 37 centered on the X axis and converging downwards, intended to serve as a seat for the ball 20.
  • Legs 38 extend upward this recess 37 so as to constitute a cage 45 in which the ball 20 is retained, with a possibility of deviating from its seat 37 when the product is taken from the container.
  • These legs 38 are four in number in the example described and have each a tooth 39 projecting radially inward.
  • teeth 39 are bevelled so as to facilitate the introduction of the ball 20 from above in the cage 45.
  • the legs 38 deform elastically radially outward to allow the teeth 39 to be crossed by the ball 20 when it is placed in the cage 45.
  • the bottom of the recess 37 communicates by a bore 41 with the inside of the end piece 42, in which the plunger tube 21 is force fitted, as shown in Figure 1.
  • the end piece 42 is thus closed and a product rise in the product is avoided. pump, which reduces the risk of accidental product leakage during transport of the container.
  • pump 1 The operation of pump 1 is as follows.
  • the volume of the pumping 43 increases, causing a depression therein, raising the ball 20 of the suction valve and the product suction in the bottom of the container 6 by the dip tube 21.
  • the ball 22 of the discharge valve is then pressed against its seat 31 and isolates the central duct 16.
  • an air intake is allowed in the container 6 during the movement of raising the pusher 2 thanks to the fact that the vent 26 communicates with the outside of the container via the annular space 25.
  • the air first passes between the mounting skirt 4 and the outer skirt 13 of the pusher 2, then gains vent 26 along the annular space 25.
  • the upward stroke of the pusher is substantially equal to the distance 1 separating the vent 26 from the lower part 23 of the inner skirt 12 when the pusher is in the low position.
  • the interior of the container 6 again ceases to communicate the exterior for a good conservation of the product contained in the container 6.
  • the ball 20 of the suction valve is then pressed against its seat 37, preventing a return of the product in the container 6, while the ball 22 of the valve distribution lifts under the effect of the pressure of the product and allows it to flow by the central duct 16 then by the lateral duct 17 to reach the dispensing orifice 40.
  • a pump having few constituent elements, namely in the example described a pusher 2 and a fixed part 3 each made at with the exception of the two balls and the spring, in one piece by molding respectively in polyethylene and polypropylene, particularly inexpensive to manufacture and of a reliable operation.
  • the pump allows the product to be stored away from outside air even when the pusher is left in the high position for a long time.
  • the invention is not limited to an air return pump as this has just been described but also applies to a pump without air intake, the product to be dispensed being in this case contained for example in a deformable pocket capable of shrink as the amount of product it contains decreases.
