Definitions

  • the present invention relates to a dispensing pump configured to be mounted on a product storage and dispensing container for dispensing product stored therein.
  • the invention relates to a pump in which product is dispensed by deforming a variable-volume pumping chamber either by hand or using an actuating member.
  • Dispersing pumps are already known in the art.
  • Document EP B 0 900 598 describes a pump for a fluid cosmetic product, which comprises a pumping chamber that can be elastically deformed under the action of a push-button and which is associated with a product inlet valve.
  • the valve communicates with a container on which the pump is mounted and is also associated with a product dispensing valve via which the product is delivered as it leaves the pump.
  • the push-button is actuated in an overall direction that is coaxial with the container, thus imposing limitations on how the pump can be used.
  • a dispensing pump for dispensing shampoo which comprises, mounted in a cylindrical support itself fixed to the neck of a container, a dip tube, a pumping chamber, and an axially actuated dispensing member. Valves are provided on each side of the distribution chamber.
  • actuation is in a direction coaxial with the tube.
  • the pump also comprises a relatively high number of parts, making it relatively expensive to manufacture.
  • the pumping chamber is produced in the form of a bellows, this meaning that it has to be manufactured separately from the dip tube and the actuating member.
  • a bellows means that it is difficult to have effective control over the deformation experienced by the pumping chamber upon actuation, leading to poor control over the dose dispensed and poor repeatability of dispensed doses.
  • the use of a bellows presents additional problems of reliability, particularly when using a large-diameter pumping chamber, as the bellows is liable to rupture eventually.
  • the pumping chamber be produced in such a way as to make it radially deformable, either by hand or under the action of a trigger provided with an operating lever which, during operation, presses laterally against the deformable wall of the pumping chamber.
  • the pumping chamber in the form of a flexible tube that may extend right into the reservoir to form a dip tube.
  • FR 1 508 161, GB A 2 182 726, U.S. Pat. No. 4,631,008, U.S. Pat. No. 3,066,832, U.S. Pat. No. 3,881,641 and FR 2 389 105 provide information as to how to produce such pumps.
  • the pumps described in those documents are trigger operated which generally means that the product has to be dispensed in just one position, either head up or head down.
  • the tube used to produce the pumping chamber typically has no valve, which means that if the pump is unused for a lengthy period of time, there is a risk that the product will become impaired and the pump blocked, especially if the product is viscous.
  • the doses that can be dispensed are relatively small.
  • FR 2 341 518 describes another type of dispensing pump comprising a dip tube inserted in a container and internally comprising two valves delimiting a pumping chamber, and a member for actuating the pumping chamber in order to deform it radially.
  • the dip tube here is made in two parts and comprises, particularly in the region of the pumping chamber, a flexible internal tube and a member covering this tube.
  • This cover member comprises a rigid outer tube, or sleeve, fixed to the neck of the container, and the actuating member comprises a stem that fits in between the elastically deformable tube and the rigid tube and acts upon a part of the dip tube located inside the volume of the container.
  • the dip tube has a relatively complicated structure and its assembly is difficult to reconcile with high production rates.
  • the cover member made of a metallic material being in contact with the product, may cause undesirable interactions with the product and may, in particular, bring about physio-chemical changes to the product, for example it may cause the product to take on a different color.
  • a subject of the invention in one of its aspects, is a dispensing pump arranged to be mounted on a product storage and dispensing container comprising a variable-volume pumping chamber, and a dip tube having a first end able to be inserted inside the container where it picks up product and a product-dispensing second end at the exit from the pumping chamber.
  • the dip tube has two valves and at least one elastically deformable portion running between the valves that delimit the pumping chamber.
  • the invention thus makes it possible, by virtue of the fact that the pumping chamber is produced in the form of an elastically deformable portion of a dip tube delimited by two valves, for letting product into the chamber and for dispensing the product, to produce a pump from a relatively small number of parts and at low cost, making it possible to offer various actuating options, while at the same time reducing the risk of product impairment.
  • a pump such as this can be produced from a single type of material, thus offering an advantage from the standpoint of the recycling of the parts employed.
  • the tube is produced by extrusion. This arrangement considerably simplifies the manufacture and assembly of the pump, and in particular, the production of the dip tube.
  • the elastically deformable portion and the dip tube can be produced as a single piece.
  • the first end has an end region set back relative to a free end of the tube.
  • the first end of the tube has a cutout.
  • the free first end of the tube has at least one slot particularly of triangular, square, or rectangular cross section.
  • the free first end of the tube is mitred or has an overall corrugated shape.
  • this first end of the tube is cut in a relatively easy way using a linear and sequential process.
  • the chosen shape allows part of the dip tube to be in contact with the closed end of the container while at the same time allowing product contained in this container to be collected.
  • At least one of the valves is added to the tube and held therein by friction, clamping, or force-fitting.
  • the tube when at rest, typically has a cross-section of constant size.
  • the cross section of the tube has a size, particularly a diameter, preferably of between 3 mm and 15 mm, more preferably between 8 mm and 12 mm, and more preferably of about 10 mm.
  • the tube may also advantageously engage, if appropriate fixedly, directly with the neck of the container.
  • the external wall of the tube may engage with the internal wall defined by the mouth of the container.
  • At least one of the valves is formed with an element chosen from a ball valve, a disc valve, a slot valve, a gate valve in which the shutter has a translational movement, a flap valve in which the shutter has a pivoting movement, and a needle valve.
  • the second end of the tube has a self-closing peripheral wall capable of opening under the effect of a raised pressure caused when the pumping chamber is deformed.
  • the pump further comprises a product applicator mounted on the second end of the tube.
  • the actuating member may also comprise a pump actuating member capable of deforming the pumping chamber.
  • the actuating member may be designed to create suction within the tube. It may be positioned between a dispensing valve and a mouth of the container defining a mounting opening for the tube. More generally, the actuating member may run between the opening and the dispensing head. This actuating member may be mounted such that it can be removed, if appropriate so that it is interchangeable.
  • This actuating member can thus be provided on an external part of the tube that projects out of the container.
  • this member may extend outside the interior volume defined by the container, and may potentially do so exclusively.
  • the mouth may itself form an actuating surface that the user may, for example, use as a surface to which he or she applies force in order to deform the cross section of the tube, particularly by folding or bending it.
  • This external part may also be large enough to allow the user to operate the tube with his or her fingers directly, such as by compressing the tube.
  • the dispensing valve may also be provided in the external part of the dip tube that projects out of the container.
  • the inlet valve may for its part lie within the interior volume of the container.
  • the inlet valve may also be provided outside of this volume.
  • the actuating member may comprise a clamp.
  • It may also comprise a tab capable of allowing the tube to be twisted.
  • the actuating member may also comprise a member for lengthening the tube.
  • the actuating member may comprise a trigger equipped with a first end region that can be actuated by hand, and with a second end region, at the opposite end to the first end region with respect to an axis about which the trigger is articulated and which region is firmly attached to the tube.
  • a product storage and dispensing container comprising a reservoir for storing the product.
  • This container further comprises a pump as defined hereinabove.
  • the first end of the dip tube extends, inside the reservoir, down near to the closed end of the reservoir, or even into contact with the closed end
  • the reservoir contains a flexible pouch on which the pump is mounted.
  • the container may further comprise a rigid outer shell surrounding the reservoir.
  • the reservoir is made of a rigid material, the pump comprising an air intake passage.
  • a further subject of the invention is a method of dispensing a product using a pump as defined hereinabove, this method involving the steps of deforming the dip tube by locally reducing the cross section of the tube at least in the region lying between the valves, collecting a dose of product, and filling the pumping chamber by releasing the tube.
  • the tube when the tube is being deformed, it is being deformed by bending it.
  • the tube may also be deformed by compressing it.
  • the tube may alternatively be deformed by lengthening the tube.
  • the tube may be deformed by twisting it.
  • a dispensing pump intended to be mounted on a product storage and dispensing container, comprising a variable-volume pumping chamber, and a dip tube having a first end able to be inserted inside the container where it picks up product and a product-dispensing second end at the exit from the pumping chamber, in which the dip tube defines an axis of elongation and at rest has a cross section of substantially constant size, the tube comprising two valves, at least one elastically deformable portion running between the valves that delimit the pumping chamber.

  • the container 1 comprises a reservoir that has a closed bottom end 3 and an open top end 4 forming a neck, on which the pump 2 is mounted, for example by screwing.
  • the container is, for example, intended to contain a cosmetic or care product.
  • the cosmetic product is to be understood to mean a product as defined in Commission Directive 93/35/EC of 14 Jun. 1993.
  • the pump 2 essentially consists of a dip tube 5 which comprises a lower end 6 via which the product contained in the container 1 enters the tube 5 and which extends into the container toward the closed bottom end 3 of the container 1 , particularly in contact with the end wall 7 of the container, and an opposite top end 8 which extends out of the container and via which the product is dispensed as it leaves the pump.
  • the tube 5 at rest, advantageously has a cross section of constant size.
  • This cross section is advantageously circular but could equally well be of another shape such as polygonal, particularly square, or oval.
  • This cross section may have a size and, in particular a diameter, preferably between 3 mm and 15 mm, more preferably of between 8 mm and 12 mm, and in particular of about 10 mm.
  • the lower end 6 of the dip tube may extend into contact with, or, preferably, up to 10 mm away from, the end wall of the container.
  • the tube 5 may be mounted on the container using a fastener.
  • This fastener may involve a clip-fastening, screw-fastening or crimping ring to be mounted on the neck of the container as a tight fit.
  • the tube 5 may be provided with a threaded ring b, screw-fastened onto the neck of the container and thus holding the tube 5 in place, for example through friction.
  • the container may alternatively be provided with a cap (not depicted) that fits over the top end of the tube.
  • one way in which the pump works is essentially based on deforming a pumping head formed by a manually accessible portion 9 of the tube 5 which therefore extends out of the container 1 .
  • the dip tube 5 is at least partly made of an elastically deformable material, particularly the portion 9 .
  • the stiffness constant of the tube is preferably 4000 N/m.
  • the stiffness constant of the tube is advantageously between 3000 N/m and 6000 N/m, to ensure comfortable and efficient working of the tube.
  • the tube 5 and the portion 9 are typically produced as one piece.
  • the tube 5 is made as one piece by extruding a flexible plastic.
  • this tube could just as well be produced by a molding operation, such as a rotational molding or an injection molding operation.
  • producing the tube by extrusion is also advantageous in that it allows the production of a very long tube, for example one more than three centimeters, particularly more than eight centimeters, and even more particularly more than twelve centimeters long, with a diameter that is constant.
  • the tube 5 is also advantageously a one-walled tube, that is to say a tube that has no sleeve or outer wall.
  • all the component parts of the pump are made of one and the same type of material such as one or more plastic.
  • deformation is produced by taking hold of the tube 5 by hand, in the portion 9 that forms the pump body and, in particular, by squeezing it between two fingers D, for example between the thumb and index finger, so as to apply a force in a radially inward direction (arrow F 1 ).
  • the manually operable region 9 is delimited by a bottom valve, referenced 10 , and by a top valve, referenced 11 , positioned facing one another so that they operate in the same direction.
  • the tube is made as one piece and, in particular, because the tube can be produced by extrusion, it is possible to produce a dip tube that has an elastically deformable region delimiting a pumping chamber and also incorporating valve seats S.
  • the bottom and top valves consist of valves of the ball valve type, with the balls, such as B, resting, when at rest, on a seat S. They are each positioned in the tube 5 in such a way that when a raised pressure caused by a force, in this instance a transverse force, is applied to the tube in such a way as to cause a resultant deformation that leads to a localized reduction in cross section, one of the valves, namely the bottom valve 10 , closes (arrow F 2 ), while the other valve, namely the top valve 11 , opens and a dose of product is dispensed through the top valve 11 and then to the pump outlet (arrow F 3 ).
  • the elastically deformable and manually operable region 9 of the dip tube 5 constitutes a variable-volume pumping chamber axially delimited by the bottom and top valves, which can be locally compressed in order to reduce its volume and cause a dose of product to be dispensed.
  • the pumping chamber following release, returns to its initial volume in order to admit product because of the elasticity of the wall of which the tube is made.
  • the lower end 6 of the tube 5 is therefore desired to be upstream of the pumping chamber while the top end 8 extends downstream of the pumping chamber.
  • the tube and, in particular, the pumping chamber are typically produced from a material that can easily be deformed by hand, while being unlikely to allow unwanted actuation of the pump, and which is capable of returning to its initial position, at the same time drawing in product, all this according to the nature of the product to be drawn in.
  • producing the tube using extrusion is advantageous insofar as it allows the production of a tube and, in particular, of a pumping chamber, that provides better control of the dose of product dispensed.
  • the tube 5 may be made of elastomer, for example elastomers of the SBR or CR type, such as the elastomers marketed under the names NEOPREN® or BAYPREN®, of the EPDM or EPM type, such as the neoprenes marketed under the names VISTALON®, POLYSAR EPM®, BUNA EP® or NORDEL®, of the FPM or FKM type, such as the elastomers marketed under the trade names TECHNOFLON®, FLUOREL®, AFLAS® or VITON®, of the MQ, MVQ, MPQ, FVMQ or FMQ type, such as the elastomers marketed under the trade names TYGOPRENE®, SYLOPRENE®, SYLASTIC®, FSE®, SYLON®, ELASTOSIL®, or RHODORSIL®, of the EVM type such as the LEVAPREN, LEVAMELT®, BAYMOD L®
  • thermoplastic elastomers of the TPO or TPV type such as the elastomers marketed under the names ENGAGE®, SANTOPRENE®, TREFSIN®, SARLINK® or ALCRYN®, or the SBC, TPU, PEBA type or those based on Propylene Ethylene such as the elastomers marketed under the names MULTIFLEX TPE®, PEBAX® or ADFLEX®.
  • thermoplastics of the EVA or VLDPE type such as the thermoplastics marketed under the names EVATANE®, GREENFLEX®, ESCORENE ULTRA® or CLEARFLEX®.
  • the pump is produced with a small number of parts, the number of materials of different kinds in contact with the fluid that has to be circulated is minimized. Furthermore, actuating the pump by deforming the dip tube by hand allows, as will be described in detail later, wide flexibility in its use, allowing various operating options and furthermore allowing for particularly quiet operation.
  • the amount of product dispensed depends on the extent to which the tube is deformed. Specifically, the dose of product dispensed by the pump is equal to the variation in volume caused by the mechanical deformation applied to the flexible tube. It is therefore possible to deliver different doses, from one use to another, according to the user's desires and, if appropriate, to deliver large quantities of product.
  • the tube may be mounted on the container by a fastener, it may also as an alternative be possible to mount the tube in such a way that it comes into direct contact with the internal wall of the neck so that the neck holds the tube in place by friction so as to obtain a sealed assembly, it then being possible to omit the fixing ring.
  • the top end 8 may be provided with a dispensing member. It is possible, in this regard, and as illustrated in FIG. 1 , to provide the tube 5 with a dispensing head 12 , for example push-fitted onto the top end 8 of the tube to make dispensing easier, and in particular to improve precision.
  • the dispensing head may comprise a duct of small cross section or may be fitted with a nozzle provided with a swirl-inducing system.
  • applicator or dispensing member may be mounted on the top end of the tube 5 .
  • Members such as a porous element, rollerball, etc. type may be used in this regard.
  • the tube was deformed by squeezing the tube manually between two fingers D, with reference to FIG. 3 it is possible to fit the pump head with a pump actuating member.
  • the pumping chamber extends, at least in part, outside of the container.
  • the user when it is intended to be operated by hand, the user can easily position his or her fingers on the elastically deformable pumping chamber in order to actuate it by hand.
  • this member when use is made of an actuating member, this member is mounted on the outside of the container in such a way that it can be replaced should it malfunction or changed if there is any desire to change the way in which the pumping chamber is actuated.
  • the tube is provided with a clamp P of which two branches 13 and 14 locally surround the manually accessible region 9 and can be brought closer together by hand (arrow F 4 ) in order to deform the tube transversely.
  • the clamp P may be made of an elastically deformable material capable of avoiding preventing the filling of the pumping chamber.
  • the clamp may be made of a rigid, non-deformable, material provided with an articulation returned to the rest position in the released position, by virtue of the flexibility of the tube.
  • the tube is deformed by compressing it
  • the free end of the tube may then be provided with a fixed stop produced, for example, in the form of a relief 15 , to make the pump head easier to actuate.
  • a fixed stop produced, for example, in the form of a relief 15 , to make the pump head easier to actuate.
  • the mouth of the container particularly the internal edge delimiting the opening of this mouth, may form a surface actuating the pumping chamber by folding the tube at this point.
  • the pumping chamber is deformed by applying torsion to the tube by twisting it. This can be done by applying a torsional force to the tube and thereby reducing the volume of the pumping chamber. As visible in FIG. 6 , the pump head may then be fitted with a tab 16 to make it easier to apply the torsional force (arrow F 6 ).
  • the tube may alternatively be deformed by elongating it.
  • a lengthening member may be provided on the ring b, this member comprising a trigger 17 comprising a first end region 17 a that can be actuated by hand in a direction that is generally transverse (arrow F 10 ), a second end region 17 b firmly attached to the free end 8 of the tube, and a middle part 17 c bearing against or articulated to a base 18 secured to the ring b.
  • dispensing is in a direction essentially transverse or essentially oblique to the overall axis X-X′ of the tube, the pumping chamber then being configured in such a way as to form an elbow inserted and guided in a groove 19 made in the base.
  • the second end region 17 b forms a fork on which there rests a collar 20 made near the free end of the tube 5 and, in particular, the face of the collar situated on the opposite side to the end of the tube 5 .
  • the second end region 17 b applies a lateral or, in general, an oblique, force to the collar 20 and as a result causes the pumping chamber to lengthen.
  • This deformation by lengthening causes a reduction in the cross section of the tube and causes a dose of product of a size corresponding to the amount of deformation to be dispensed.
  • the pumping chamber is delimited by a bottom valve 10 and by a top valve 11 .
  • the top and bottom valves each consist of a ball valve.
  • the valve comprises a body 22 which has a generally cylindrical external peripheral surface and a closed end provided with one or more passages 23 and which internally comprises a housing accommodating a ball B delimited, on the one hand, by the closed end 23 and, on the other hand, by an annular seat 24 against which the ball B rests when the valve is in the open position.
  • a ball valve in place of a ball valve, a slot valve ( FIG. 11 ), a disc valve ( FIGS. 12 and 13 ) in which a moving disc 25 , held by elastically deformable lateral branches such as 26 , closes a product flow orifice, or alternatively a gate valve in which the shutter can move translationally ( FIG. 14 ), a needle valve ( FIG. 15 ), or alternatively a flap valve in which the shutter is able to pivot ( FIG. 16 ).
  • valve is produced from a flexible material, for example a flexible elastomer.
  • a flexible material for example a flexible elastomer.
  • the inlet or bottom valve 10 that lets product into the chamber may be provided in the interior volume of the container, while the delivery valve that dispenses product may extend outside of the container, that is to say beyond the neck of the container.
  • the pumping chamber extends at least partly outside of the container.
  • the dip tube comprises a part which is inserted in the container and thus falls inside the interior volume of the container and extends as far as the mouth, and a part external to the container, that projects out of the container and of its mouth. This projecting part may serve to attach the actuating member.
  • At least the internal part may have no covering sheath or external sleeve, over at least 50% of its height, preferably over 75% of its height, and as a preference over its entire height, so that over its height via which the tube is intended to be inserted into the tube in contact with the product, the volume reserved for the product in the container can be greater. It is also possible to envisage at least the external part of the tube having no cover member.
  • the tube may possibly be devoid of any cover member over its entire height, possibly except for the height of a dispensing head attachment section. This partial or complete lack of cover member makes it possible to avoid potential physio-chemical modifications to the product contained in the container, particularly when this cover member is made of (a) metallic material(s).
  • the second end 8 of the pumping chamber may alternatively be produced in the form of a self-closing peripheral wall, that is to say of a wall which is closed in the rest position ( FIGS. 17 and 18 ).

  • the pumping chamber is released, the end of the pumping chamber will spontaneously close itself again to let product into the chamber.
  • valves are preferably produced in the form of an added element inserted into the dip tube 5 and held therein by friction, clamping or force fitting. This embodiment has the advantage of reducing costs and enhancing ease of use.
  • the valves are kept in place by elastic deformation of the tube.
  • the valves Preferably, the valves have a length greater than their diameter.
  • the dip tube 5 will preferably be produced in such a way that its free end bears against the surface of the end wall 7 of the container 1 .
  • the container 1 can be completely emptied, it then becoming easier for liquid to be drawn up from the closed end of the container.
  • this end of the tube is configured in such a way that it has an end region 27 which is set back from the free end 28 .
  • this set-back region may be produced in the form of a slot of triangular, square or rectangular overall shape.
  • the pump system that has just been described may advantageously be used under conditions of the “airless” type, that is to say packages in which the products are stored out of contact with the air.
  • the container essentially comprises a flexible pouch 29 on which the pump 2 is mounted.
  • the reservoir may alternatively also have a rigid outer shell 30 that conceals or protects the flexible pouch 29 .
  • the invention is not of course restricted to the embodiments described or envisaged.
  • the embodiments whereby the tube is made as a single piece by extrusion, the embodiments whereby the tube at rest has a cross-section of constant size, the embodiments whereby the elastically deformable pumping chamber is accessible from the outside, and the embodiments whereby use is made of pumping chamber actuating means that involve applying torsion to or twisting the tube may be envisaged independently of one another and, as appropriate, combined with all the other alternative forms envisaged earlier.
