Definitions

  • the present invention relates to a pump intended to be mounted on a container and allowing to distribute a product in different positions, including head at the top or upside down.
  • the patent application FR 2 528 122 discloses a pump enabling distribute a product head up or upside down, having a pump body and a movable assembly in the pump body, defining therewith a chamber of pumping of variable volume.
  • the pump body has an opening allowing the product contained in the container to enter the pumping chamber when the pump is used upside down.
  • the moving assembly includes a lip for isolating the aforementioned opening of the pumping chamber after a certain depression in the body pump. If the pump is held upside down for a long time, there is a risk of leakage product by this opening is not excluded, especially if the product is low viscosity.
  • Patent US Pat. No. 5,622,286 discloses a pump with an orifice in the body pump, this orifice allowing only a return of air and not the supply of the pumping chamber when the pump is upside down.
  • the invention aims in particular to propose a pump which has a structure relatively simple while allowing a product to be satisfactorily distributed, even slightly viscous, head up or upside down.
  • the invention can make it possible to realize the pump with a recovery passage of air which can extend at least partially into the pump body, for example by means of a game formed between a rod of the moving assembly and the fixed part. This can avoid having to implement complex and expensive sealing means to achieve between the rod aforementioned and the fixed part.
  • the invention also allows in the case where the air intake is carried out thanks to a clearance between the rod and the fixed part to reduce the risk of product leakage in case of holding the pump down, either at rest or when the moving assembly is in an end position in the pump body, since the second lip can avoid the product entering through the opening to gain from the inside of the pump body the air intake passage and flow out of the pump.
  • the pump comprises an annular seal intended for between the fixed part and the upper end of the neck of the container on which the pump is mounted, this seal having a radially inner portion which on the one hand may be applied to the pump body to prevent the product contained in the container to flow outwards and secondly can deviate from it under the effect of a depression in the container to allow air to be drawn in.
  • the seal not apply on the pump body. However, the clearance between the seal and the pump body is then weak enough to prevent the passage of the product, while allowing the passage of the air.
  • the pump comprises a base part for fixing the pump to the container, the pump body being fixed, in particular by snapping, on this base part.
  • the aforementioned air intake passage may be formed at least partially between this basic part and the pump body.
  • At least one of the first and second lip is arranged to permanently apply to the pump body, and preferably both lips are permanently applied to the pump body.
  • the first lip may have a substantially frustoconical shape diverging towards the pumping chamber and the second lip an arched shape concave towards the inner surface of the pump body, applying by lower edges and upper on the pump body.
  • the moving assembly can comprise a shutter arranged to close an outlet passage of the product when the volume of the pumping chamber increases and to release this passage when the volume of the pumping chamber decreases and that the product pressure in the chamber of pumping reaches a predefined value.
  • the pump comprises other mechanisms with pre-compression or is not pre-compression.
  • the moving assembly may comprise an interior space into which the outlet passage of the product and wherein the shutter is disposed.
  • This shutter may comprise a tubular body closed at its end upper portion by a substantially frustoconical portion, adapted to seal the passage of product release.
  • the shutter may further comprise an annular lip, outside the body tubular, adapted to be applied on a wall delimiting the aforementioned interior space, this annular lip, when the pump is observed head up, having a shape substantially frustoconical diverging upward and below the passages communicating said interior space and the pumping chamber.
  • the shutter can be recalled in its closed position by an element of elastic return disposed in the interior space, this elastic return element being example a helical spring working in compression.
  • the pump comprises an elastic return element adapted to recall the moving assembly in its rest position.
  • This elastic return element can be arranged in the pumping chamber and comprise a helical spring working in compression.
  • This reminder element could also, without leaving the scope of the the present invention, be disposed outside the pumping chamber, particularly if one wish to avoid contact with the product.
  • the pump body is arranged to allow the attachment of a dip tube.
  • the pump comprising a suction valve closing when the volume of the pumping chamber decreases and opens when the volume of the pumping chamber increases, this valve can be arranged to allow the feeding of the chamber pumping product through the dip tube when the pump is used head up.
  • the subject of the invention is also a container equipped with a pump such that previously defined.
  • the pump 1 shown in Figures 1 and 2 is intended to be mounted on a neck 52 of a container 53, apparent in Figure 3, containing a product P to be dispensed by for example a low viscosity product such as a perfume.

  • the base part 4 could be fixed otherwise on the neck of the container without being outside the scope of the present invention, by snapping, gluing, welding or crimping for example.
  • the fixed part 2 further comprises a pump body 16 defining with the moving assembly 3 a pumping chamber 17, of variable volume.
  • the moving assembly 3 comprises a piston 30 made in one piece with a hollow rod 31 at the upper end of which is fixed a push-button 25.
  • the mounting skirt 5 is extended upwards by a collar 7, surrounding a central portion 8 of the base portion 4.
  • This central portion 8 has two walls tubular 9 and 12, coaxial, interconnected by an annular wall 11 at their end upper part, and defines an annular groove open towards the bottom, in which is engaged the pump body 16.
  • the central portion 8 is connected, at its lower end, to the neck 7 by a annular wall 10 extending perpendicular to the axis X.
  • This passage 13 defines at its lower end a frustoconical surface 13a of X axis, diverging towards the bottom, against which can come to bear sealingly a corresponding frustoconical surface 31a of the rod 31, converging up, when the pump is at rest, as shown in Figure 1.
  • the tubular wall 9, radially the outermost, comprises, on its face radially inner, a bead 14 for snap-fastening the body of pump 16 on the base part 4, the pump body 16 having for this purpose to its upper end an annular bead 23.
  • the base portion 4 carries an annular seal 51 intended for to be inserted between the annular wall 10 and the upper end of the neck 52 of the container 53, as shown in Figure 3.
  • the radially inner portion 51a of the seal 51 comes normally apply against the pump body 16 to prevent the product contained in the container to flow outward.
  • the pump body 16 has in the example considered a portion 16a cylindrical of revolution about the X axis and has at its lower end a end piece 18 for fixing a dip tube 19.
  • the end piece 18 defines the seat of a ball suction valve 20.
  • the latter is retained in its housing by at least one lug 21 of the pump body 16.
  • the pump body 16 comprises a opening 24, located in the example considered substantially halfway up the latter, and making it possible to put the pumping chamber 17 in communication with the interior of the container when the mobile assembly 3 is at rest, the volume of the pumping chamber being then maximal.
  • the push-button 25 has a dispensing orifice 26 made with a conventional nozzle with swirling channels 27, attached to the rest of the pushbutton, which allows the distribution of the product P in the form of a spray.
  • the rod 31 comprises a channel 29 allowing the product to gain this orifice 26.
  • the piston 30 comprises first 40 and second 41 annular lips.
  • the first lip 40 is of substantially frustoconical shape, diverging towards the bottom of the pumping chamber 14 and relies tightly on the inner surface of the cylindrical portion 16a of the pump body 16. This first lip 40 is located above of the opening 24 when the pump is in its rest position, as illustrated in Figure 1.
  • the second annular lip 41 is above the first 40, and also applies sealingly to the inner surface of the cylindrical portion 16a of the pump body 16.
  • This second lip 41 has in the example considered a arcuate, concave shape towards the inner surface of the body 16, and is applied by edges lower 41a and upper 42b on the body 16.
  • the rod 31 is extended inferiorly by a hollow end piece 32, closed at its lower end.
  • This end piece 32 is for example fixed by snapping on the rod 31, and has an outer shoulder 33 on which abuts at its end superior to a helical spring 34 working in compression, which rests by its bottom end on the bottom of the pump body 16.
  • Passages 36 are made between the pumping chamber 17, outside the the end piece 32, and the interior space 35 thereof, to allow the product contained in the pumping chamber 17 to gain the channel 29 when the volume of the pumping chamber 17 decreases.
  • the moving assembly 3 comprises, in the interior space 35, a shutter 42 movable between a closed position closing the channel 29 and a distribution position allowing the product to flow in the channel 29 to the orifice 26.
  • the shutter 42 comprises a tubular body 43, of axis X, closed to its upper end by a frustoconical portion 44 adapted to be applied against a seat made in the rod 31, to close the channel 29 when the pump is at rest, as illustrated in Figure 1.
  • the shutter 42 further comprises an annular lip 46 on the outside of the body tubular 43, adapted to be applied on the inner surface of the end piece 32.
  • This annular lip 46 has, when the pump is observed head up, a frustoconical shape diverging upwards, and is positioned below the passages 36 communicating the interior space 35 with the pumping chamber 17.
