Definitions

  • the present invention relates to a dispensing pump for mounting on a product storage and dispensing container for dispensing a product stored therein.
  • the invention relates to such a pump, wherein the product distribution is effected by deforming a pumping chamber of variable volume, manually or by means of an actuating member.
  • a pump for a fluid cosmetic product which comprises an elastically deformable pumping chamber under the action of a push button and which is associated with a product inlet valve, which valve communicates with a container on which the pump is mounted, and a product dispensing valve through which the product is delivered at the outlet of the pump.
  • the actuation of the push button is made in a general direction coaxial with the container, which greatly limits the possibilities of use of the pump.
  • this pump has a relatively high number of parts, which affects its manufacturing cost and the preservation of the environment.
  • a dispensing pump for dispensing a shampoo which comprises, mounted in a cylindrical support itself attached to the neck of a container, a dip tube, a pumping chamber and an axially actuated dispensing member. Valves are provided on both sides of the distribution chamber.
  • the actuation is carried out in a direction coaxial with the tube.
  • the pump also has a relatively large number of parts, which makes its manufacture relatively expensive.
  • the pumping chamber is in the form of a bellows, which requires its realization separately from that of the dip tube and the actuating member.
  • the use of a bellows does not effectively control the deformation suffered from the pumping chamber at actuation, which leads to poor control of the dispensed dose and poor repeatability of doses distributed.
  • the use of a bellows also has reliability problems, particularly when using a large diameter pumping chamber, the bellows being likely to break in the long run.
  • the pumping chamber so as to make it deformable radially, either manually or under the action of a trigger with a control arm that comes, in operation, press laterally on the deformable wall of the pumping chamber.
  • the pumps described in these documents are actuated by means of a trigger, which generally requires distributing the product in a single position, head up or head down.
  • the tube used to make the pumping chamber does not have a valve, so that if the pump is not used over a long period, the product may be damaged and the pump clogged, especially if the product is viscous.
  • the doses likely to be distributed are relatively small.
  • the plunger tube is here made in two parts and comprises, particularly at the level of the pumping chamber, a flexible inner tube and a cover member of this tube.
  • This covering member comprises a rigid outer tube, or sleeve, fixed on the neck of the container, the actuating member having a tail inserted between the elastically deformable tube and the rigid tube and biasing a portion of the dip tube located at inside the container volume.
  • the plunger tube has a relatively complex structure whose assembly is hardly compatible with high production rates.
  • the covering member made of metallic material, being in contact with the product may be at the origin of unwanted interactions with said product and in particular may cause physico-chemical modifications of the product, such as staining. said product.
  • the plunger tube comprises two valves and comprises at least one elastically deformable portion extending between said valves and defining said pumping chamber.
  • the invention thus makes it possible, by virtue of the production of the pumping chamber in the form of an elastically deformable portion of a dip tube delimited by two product inlet valves in the chamber and of product distribution, to provide a pump from a very small number of parts and therefore low cost, and that allows to offer several gestures of actuation, while reducing the risk of tampering with the product.
  • a pump can be made from a single type of material, thus presenting an interest from a point of view of the recycling of the parts used.
  • the tube is, according to another characteristic of the invention, made by extrusion.
  • the manufacture and assembly of the pump, and in particular the production of the dip tube, are thus considerably simplified.
  • said elastically deformable portion and said dip tube are made integrally.
  • the first end has an end zone recessed relative to a free end of the tube.
  • the first end of the tube comprises a notch.
  • the first free end of the tube comprises at least one slit of particular triangular section, square or rectangular.
  • the first free end of the tube is tapered or is generally corrugated.
  • this first end of the tube is cut in a facilitated manner in a linear and sequential process.
  • the chosen shape allows a portion of the dip tube to be in contact with the bottom of the container while allowing a product sample contained in this container.
  • At least one of the valves is attached to the tube and is held in said tube by friction, clamping or fitting.
  • the tube has at rest a cross section of constant size.
  • the section of the tube has a dimension, in particular a diameter, of between 3mm and 15mm, preferably between 8mm and 12mm, and in particular of about 10mm.
  • the tube may also be advantageously engaged, if necessary fixing, directly with the neck of the container.
  • the outer wall of the tube may come into engagement with the inner wall defined by the mouth of the container.
  • At least one of the valves is formed by a member selected from a ball valve, a disc valve, a slit valve, a flap valve movable in translation, a flapper flap pivotally mounted, and a needle valve.
  • the second end of the tube comprises a self-enclosing peripheral wall capable of opening under the effect of an overpressure generated during the deformation of the pumping chamber.
  • the pump further comprises a product applicator mounted on the second end of the tube.
  • the organ Actuation can be adapted to create a depression within the tube. It can be positioned between a dispensing valve and a mouth of the container defining a mounting aperture for said tube. More generally, the actuating member may extend between said opening and the dispensing head. This actuating member may be removably mounted, if necessary so as to be interchangeable.
  • This actuating member can thus be provided on an outer portion of the tube projecting from the container.
  • this member may extend out of the interior volume defined by the container, and possibly exclusively.
  • the mouth may itself itself form an actuating surface by serving, for example, to the user of the biasing surface to deform the section of the tube, in particular by folding or bending.
  • This outer portion may still be large enough to allow digital actuation of the user on the tube, such as by compression of the tube.
  • the dispensing valve may also be provided in the outer portion of the dip tube protruding from the container.
  • the inlet valve can be inscribed in the interior volume of the container.

  • the tube 5 and the portion 9 are made in one piece.
  • the tube 5 is made in one piece by extrusion of a flexible plastic material.
  • this tube could also be made by molding such as a rotational molding or injection.
  • extrusion of the tube is also advantageous insofar as it makes it possible to produce a tube of great length, for example longer than three centimeters, in particular longer than eight centimeters, and more particularly longer than twelve. centimeters, and this with a constant diameter.
  • the tube 5 is also advantageously single-walled, that is to say that it has no sheath or external wall.
  • all the components of the pump are made of the same type of material such as plastic material (s).
  • the deformation is effected by manually gripping the tube 5, in the portion 9 forming the pump body, and in particular by pressing it between two fingers D, for example between the thumb and the index, so as to exert a force in a radially internal direction (arrow F1).
  • the zone 9 manually operable is delimited by a low valve, referenced 10 and a high valve, referenced 11, arranged vis-à-vis so as to operate in the same direction.
  • the up and down valves are constituted by ball-type valves, such as B, resting, in the rest position, on a seat S. They are each arranged in the tube 5 so that when an overpressure generated when a force, here transversal, is applied to the tube so as to cause a subsequent deformation generating a localized section reduction, one of the valves, namely the bottom valve 10 closes, while the another valve, namely the top valve 11 opens (arrow F2) and a dose of product is distributed through the top valve 11 and to the pump outlet (arrow F3).

  • the zone 9 elastically deformable and manually operable plunger tube 5 constitutes a pumping chamber of variable volume delimited axially by the low and high valves, which can be locally compressed to reduce its volume and cause a distribution of a dose of product, the pumping chamber taking, after relaxation, its initial volume for the product admission, thanks to the elasticity of the constituent wall of the tube.

Moreover, the actuation of the pump by manual deformation of the plunger tube makes it possible, as will be described in detail below, a great flexibility of use by allowing different gestures and also allows a particularly quiet operation.
  • the amount of product dispensed depends on the extent of deformation of the tube. Indeed, the dose of product dispensed by the pump is equal to the volume variation caused by the mechanical deformation exerted on the flexible tube. It is therefore possible to deliver different doses from one use to another, depending on the wishes of the user and, where appropriate, to deliver large quantities of product.
  • the tube may be mounted on the container by means of a fastener, it may also alternatively mount the tube so that it comes into engagement directly with the inner wall of the neck so that the neck ensures the maintenance of the tube by friction so as to obtain a tight assembly, the fixing ring can then be omitted ,.
