Definitions

  • the present invention relates to an airless distribution system also called “airless”, that is to say without air intake so that the product dispensed is never in contact with the air before its distribution, the metering being ensured by means of a non-return pump integrated in said system.
  • This type of airless distribution system is used in particular for the distribution of products which are liable to deteriorate on contact with air. It can be pharmaceutical products or cosmetic products such as care creams, of fluid consistency, that is to say liquid or pasty.
  • the fluid product is packaged in a retractable container so that the volume of the container corresponds precisely at all times of use to the residual quantity of the product that it contains, the product never being in contact with air at l inside the container.
  • this type of dispenser comprises a pump provided with a variable volume distribution chamber provided with an inlet connected to the container, and an outlet for discharging the product to be dispensed.
  • the most precise system consists in actuating a piston by a movement of return in a cylinder. This is the most conventional for an airless dispenser pump, the opening and closing movements at the inlet and at the outlet of the dispensing chamber being carried out by means of valves made up of balls or movable rigid valves.
  • the advantage of the ball is that it is smaller, which makes it possible to have a smaller pump.
  • a first airless system called “airless” is airtight from the container to a first valve located at the immediate outlet of the distribution chamber.
  • a second airless system called “full airless” is airtight from the container to the discharge opening. The second system is still much more complex and more expensive than the first.
  • the object of the invention is to provide an airless distribution system which is both efficient and simple to manufacture while retaining the traditional architecture of a pump whose distribution chamber consists of a piston sliding in a cylinder.
  • the invention thus makes it possible to merge with common constituents a metering function, that is to say the motor function performed by the push button and the pump, and a distribution function, that is to say conveying of the fluid product from the container to an outlet orifice where the discharge channel opens, these functions being carried out by means of three structural parts.
  • the non-return valves consist of a non-return valve comprising a flexible wall disposed opposite the rigid support and mounted in abutment or prestressed abutment on said rigid support to which said valve is connected by a fixed link.
  • the rigid support is perforated with at least one passage arranged opposite the flexible wall.
  • the inlet valve consists of a valve bearing on the rigid support part of the hoop.
  • the outlet valve consists of a valve resting on the rigid support part of the rod or the push button depending on the solution chosen. Before mounting, the valve has a peripheral cone-shaped area. In the assembled position, said peripheral zone has a deformation of the flattening type and inducing an elongation consecutive to the bearing of the inner face of the large base on the rigid wall. This elongation induces a considerable bearing force, much greater than a non-elastic deformation, which guarantees sealing when the distribution system is "at rest" including if the container is overpressure.
  • the distribution system is "at rest” when the pressures inside the container and inside the pump as well as the atmospheric pressure are identical.
  • the pressure variation in the distribution chamber will deform the flexible wall and allow the valve to open.
  • the valve is connected to the rigid wall by a fixed non-deformable connection
  • a fixed non-deformable connection means that only part of the valve ensuring the connection to the rigid wall is fixed and not deformable.
  • This fixed part made of flexible polymer, is located in the center of the valve.
  • the flexible peripheral zone extends radially outwards from this fixing zone.
  • the fixing zone could, for example, consist of a flexible chimney part of the valve fitted on a rigid rod connected to the rigid wall.
  • the assembly of the flexible chimney and the rigid rod constitutes a rigid and sealed assembly.
  • the assembly thus produced can withstand an upstream overpressure greater than 6 bars.
  • the fixing zone cannot carry out any movement in translation, rotation or deformation of any type with respect to the rigid wall.
  • the pump comprises a distribution chamber consisting of a piston sliding in a pump cylinder and a first discharge channel.
  • the pump thus functions as both a pump and the first evacuation channel
  • the hoop comprises the pump cylinder, a first sealed connection means of the container to the distribution system as well as the rigid support support of the valve of the inlet valve.
  • the valve consists of said valve mounted to bear on said rigid support support.
  • the hoop fitted with the inlet valve cumulatively acts as a sealed connection between the container in which the fluid is conditioned and the distribution system, as an inlet valve in the distribution chamber, and finally as the cylinder which is the first component of the distribution chamber.
  • the rod comprises the piston, the first evacuation channel, as well as a second connecting means waterproof with the push button.
  • the rod is hollow throughout its length to constitute the first product discharge channel from the distribution chamber to the push button. In this way, the rod acts as a piston for the pump, as the first evacuation duct, and as a sealed connection with the push button.
  • the push button is connected to the rod by the second connecting means of said rod and comprises a second discharge channel.
  • the second evacuation channel connects the first evacuation channel housed in the rod to the evacuation orifice housed in said push button.
  • the push button is fixedly connected to the rod so that the pressure action on the push button causes the movement of the rod and by the same that of the piston in the cylinder.
  • the push button can for example be fitted on the rod.
  • the evacuation opening constitutes the outlet of the second evacuation channel to the outside.
  • the rod comprises a rigid support disposed at the outlet end of the first discharge channel, and the outlet valve consists of the valve mounted to bear on said rigid support.
  • the rod has two ends.
  • the piston is disposed at a first end of the rod.
  • the outlet end is the second end of the rod.
  • the rod is a one-piece assembly which integrates the rigid support support of the valve of the outlet valve.
  • the support consists of a shoulder disposed at the outlet of the first evacuation channel.
  • the rod is then equipped with a valve bearing on said support support and the pump is thus equipped with the outlet valve.
  • the outlet valve is thus disposed at the outlet of the dispensing chamber and the dispensing system is airtight from the container to the outlet of the dispensing chamber.
  • a second outlet non-return valve is arranged in the discharge orifice, the push button then also comprising a rigid support disposed in the discharge orifice and the outlet valve consisting of the mounted valve. resting on said rigid support.
  • the push button is a one-piece assembly which incorporates a rigid support for the valve of the second outlet valve. Said bearing surface is constituted by the free end of a rod housed in the center of the discharge orifice, said rod being in one piece with the push button.
  • the push button is then fitted with a valve housed in the evacuation orifice, the flexible wall of the valve is supported on the support support formed by said free end.
  • the pump is then fitted with a second outlet valve.
  • the pump is therefore equipped with two outlet valves, the first of which is disposed at the outlet of the distribution chamber and the second is disposed in the outlet orifice of the distribution system; the second valve obtains the closure of said discharge orifice.
  • This version has the advantage of great safety, the two outlet valves having a double air barrier.
  • the second outlet valve housed in the orifice being in contact with the outside, may deteriorate for a reason of shock, fall or due to any attack. In this case, the distribution system is always airtight until it leaves the distribution chamber.
  • the push button comprises the rigid support disposed in the discharge orifice, the outlet valve consisting of the valve mounted to bear on said rigid support.
  • the pump is therefore equipped with a single outlet valve which simultaneously ensures the closure of the discharge orifice. She has the advantage that the dispensing system is sealed from the container to the dispensing orifice.
  • the invention also relates to an assembly comprising a distribution system with at least one of the preceding characteristics. It is characterized in that the distribution system is fixed on a container and in that the assembly is airtight from the container to the outlet valve of the most downstream pump. The assembly is thus sealed from the container to the exit of the first evacuation channel in the first embodiment. The assembly is thus sealed from the container to the discharge orifice in the second and the third embodiment.
  • the top of the distribution system corresponds to the push button and the bottom to the hoop in contact with the container.
  • the product flows from the container upstream of the distribution system to the outlet orifice downstream of said distribution system.
  • the valve disposed in the dispensing orifice is therefore located downstream of the valve disposed at the outlet of the first discharge channel.
  • the illustrated distribution system figure 1 includes a hoop 2, a push button 3, a return spring 4 constituting a return system, a rod 5 and two valves.
  • the valves each include a valve 6 and 7 having a flexible wall 60 and 70 peripheral located opposite the rigid support 24 integral part of the hoop 2 for the valve 6 and the rigid support 52 integral part of the rod for the valve 7.
  • the rigid support is perforated by at least one orifice 6 or 7 located opposite the flexible wall of the valve.
  • the valve is in the closed position when the peripheral flexible wall 60 or 70 of the valve is respectively in contact with the rigid support 24 or 52 over its entire perimeter and in the open position when the peripheral flexible wall 60 or 70 of the valve is distant from the rigid support on at least part of this perimeter, the valve 6 or 7 and the rigid support 24 or 52 constituting a sealed assembly when the flexible peripheral wall of the valve 6 or 7 is in contact with its entire perimeter with the rigid support 24 or 52.
  • the valve 6 or 7 is respectively connected to the rigid support 24 or 52 by a non-deformable fixed connection.
  • the valve passes from the closed position to the open position by deformation of the peripheral zone of the valve 6 or 7.
  • the flexible walls 60, 70 of the non-return valves 6 and 7 are cone-shaped.
  • the flexible walls 60, 70 will be deformed during assembly by the pressing and stressing of the internal face of the large base of the cone on the rigid support 24 or 52.
