Definitions

  • the present invention relates to a valve housed in the outlet nozzle of an airless distribution system also called “airless”, that is to say without air intake, assembled on a container in which is conditioned a fluid product.
  • Said nozzle comprises an outlet channel opening onto an outlet orifice, the valve closing the outlet orifice when the dispensing system does not deliver the conditioned product into the container.
  • the tip fitted with such a valve is commonly designated by the term shutter tip.
  • Airless distribution systems are designed to prevent the product packaged in the container from coming into contact with air before it is dispensed. They are used to dispense fluid, liquid or pasty products which must not be in contact with air before their use, for example - without exclusive - pharmaceutical or cosmetic products. See for example EP1702862 .
  • These distribution systems are generally equipped with a non-return pump to ensure dosing and allow the evacuation of the packaged product in the container.
  • the conditioned product circulates from the container to the pump, then from the pump to the discharge orifice under the effect of the movement imparted to the pump by means of a push button.
  • the pump is normally equipped with an inlet valve and an outlet valve to allow its operation. At rest, when the dispenser is not in use, said valves are closed. The conditioned product is therefore not in contact with the air from the container to the pump outlet valve.
  • the object of the invention is to provide a shutter tip equipped with a valve much simpler and therefore much more reliable and inexpensive than a movable shutter valve, while having a barrier property to the air as effective as the barrier offered by said movable shutter valves.
  • the valve of the invention also offers excellent directional control of the outlet jet of the packaged product.
  • the rigid wall can be indifferently directed towards the inside or the outside of the cavity.
  • the valve according to the invention therefore comprises a valve housed in the cavity which constitutes the outlet channel when it opens onto the outlet orifice of the distribution system.
  • valve the assembly combining the outlet end of said distribution system and the valve housed in said end will be called to make a so-called shutter end.
  • the valve is thus sealed in the rest position.
  • the elastic deformation of the valve means that it is in support, that is to say in prestressed support on the rigid wall of the rod.
  • the opening and closing of the product passage are obtained by the additional deformation and therefore the displacement of the flexible wall in the axis xx 'under the effect of the product pressure resulting from the setting in motion of the pump.
  • the rod is disposed inside - substantially in its center - of a cavity pierced with a first opening, the free end of the rod being disposed in the center of said first opening, the first opening being part of a plane substantially perpendicular to the axis xx '.
  • the product can thus flow outside, the cavity and said first opening constituting the end of the outlet channel and the discharge orifice of the product distribution system.
  • the valve is equipped with a chimney, a first end of which is connected to a peripheral zone of the flexible wall, said valve is fixed to the end piece by fitting the chimney into the cavity along the axis xx ', a external face of the chimney and an internal face of the wall of the cavity describe a substantially annular form of revolution cooperating with each other, said external face being in sealed support on the internal face of the wall of the cavity, the rod being placed inside the chimney after assembly, the rod and the chimney being then substantially coaxial and concentric.
  • the valve is thus simply mounted on the nozzle by its fitting in the cavity.
  • the valve forms a one-piece assembly, the valve being made of an elastic polymer with shape memory.
  • the valve is fixed and in one piece reduces the number of parts, the connection between the valve and the end piece being made without additional assembly part.
  • the valve being made of elastic polymer with shape memory, the deformation of its flexible wall during fitting creates a pressure of this on the rigid wall of the rod and not only makes it possible to seal it at rest , but also its automatic return to the support position after evacuation outside of the product dosed in the pump.
  • the end piece forms a one-piece assembly.
  • the nozzle thus consists of the rod and the cavity located at the end of the discharge channel, the opening of the cavity constituting the product outlet orifice.
  • the flexible wall is flat when it is in abutment on the end of the rod.
  • the flexible wall can be substantially flat and substantially perpendicular to the axis xx 'without departing from the scope of the invention.
  • the flexible wall will have a cone shape, the generator of which has an angle of less than 90 ° with the axis xx ′ before mounting (cone returning inside the end piece). The deformation resulting from mounting and pressing on the end of the rod gives the wall a more or less flat convex cone shape.
  • the orifice and the projection of the end of the rod in the plane P are of circular shape. This arrangement guarantees a more homogeneous passage at any point of the perimeter of the orifice when the valve is in the open position.
  • a traditional lip obturator consists of two lips resting on one another in the form of a jaw.
  • the shutter according to the invention consists of a flexible wall perforated with an orifice, preferably circular and central, maintained in abutment on a rigid wall on its perimeter zone around the orifice. This arrangement gives perfect control and consistency of the support of said flexible wall at any point of said perimeter zone on the rigid wall. There is thus a perfect seal, equivalent to that obtained by means of a complex and fragile sealing system equipped with movable valves.
  • the system is optimized if the orifice is circular and the end of the rod in the shape of a circular cap.
  • the wall of the valve is of convex conical shape when it is supported on the end of the rod, that is to say present with the axis xx 'an angle between 90 ° and 135 ° as illustrated in figure 3 .
  • the additional deformation of the flexible wall in the axis xx ′ under the effect of the pressure of the conditioned liquid is an elastic deformation of elongation type in the vicinity of the orifice, which induces a large restoring force which guarantees sealing of the valve in the rest position after evacuation of the dispensed liquid.
  • the modularity of the opening angle between 90 ° and 135 ° makes it possible to optimize the closing force of the valve as a function of the elasticity of a previously determined polymer.
  • the orifice and the projection of the end of the rod in the plane P are of circular shape, other shapes are possible for the orifice, for example a more or less flattened ellipse shape if the he industrialist wants a more or less flattened product jet. It will then be necessary to adapt the profile of the rod in the vicinity of its end to the shape of the orifice so as to maintain a support substantially constant of the flexible wall at any point of the perimeter zone around the orifice.
  • the invention also relates to an airless distribution system with pump comprising a valve with at least one of the preceding characteristics ensuring the function of a shutter nozzle and integrated in the push button of said system, the product to be diffused being brought in through a housed channel. in the push button and opening into the cavity then escaping through the orifice through a passage.
  • the end piece and the push button may constitute a monobloc assembly, which contributes to further simplifying the device and reducing the manufacturing price.
  • the airless distribution system with pump comprises a valve having at least one of the preceding characteristics and simultaneously ensuring the function of the pump outlet valve and of the shutter end piece. This possibility stems from the high quality of the airtightness of said valve and makes it possible to further reduce the manufacturing price of the distribution system.
  • the invention also relates to a device of the flexible airless tube type having an orifice, characterized in that it comprises a valve with at least one of the preceding characteristics, said valve being housed in the orifice and constituting a shutter end piece. of said flexible tube.
  • Another type of container is the flexible tube, the volume of which can correspond at any time during its use to the residual volume of the product it contains. In a traditional mode of use, the orifice of the tube is open. When the user releases the pressure on the wall of the tube, the air enters the tube in total or partial substitution of the evacuated cream.
  • the orifice of the flexible tube is equipped with a valve constituting a closure piece.
  • This application of the invention is therefore of great interest insofar as it makes it possible to have air-conditioned packaging, without the use of a pump, more expensive than the device, and whose ergonomics are moreover ill-suited to the association with a container of the flexible tube type.
  • the endpiece also supports a second flexible valve fitted in the rod and resting on a face located opposite the first opening, said second valve constituting with the endpiece an additional non-return valve.
  • the flexible tube thus has two barriers to the entry of air into the container, the two barriers being arranged "in series" with respect to each other.
  • the tube comprises a head and the end piece constitutes a one-piece assembly housed in the orifice delimited by the wall of the head of the tube.
  • the end piece and the wall constitute a one-piece assembly.
  • the tube comprises a fixed capsule with a base and the end piece constitutes a one-piece assembly with said base.
  • This embodiment is particularly economical since the rigid support walls and the fixing means of each valve are made in the one-piece base.
  • the top corresponds to the orifice of the end piece and the bottom to the part through which the product arrives and that the interior corresponds to the middle of the end piece.
  • Tip 1 illustrated figure 1 is in one piece, it comprises a rod 11 of axis xx 'fixed on a body 10 and placed in the center of a cavity 12. This cavity 12 is pierced with a first opening 13 placed in the upper part and by a channel 14 opening into lower part of the cavity 12.
  • Valve 2 shown figure 2 is also monobloc, it comprises a flexible wall 22 pierced with an orifice 23 and a hollow cylindrical part with axis xx ′ in the form of a chimney 24.
  • the chimney 24 has an outer face 221 intended to cooperate with the inner face 121 of the cavity 12.

  • the opening of the passage between the end 111 and the wall 22 induces an elastic deformation of the elongation type of the wall 22 in the vicinity of the orifice.
