Definitions

  • the present invention relates to a method for distributing two components, in particular liquids, using a propellant, packaged separately one on the other in the same distributor.
  • the invention also relates to a distributor allowing the selective distribution of said components.
  • the dispenser according to the invention is of the "housing" type aerosol ”equipped with a dispensing valve, actuated using a push button and equipped with a distribution system.
  • a push button has a dispensing orifice through which the component (s) leaves the housing, under the thrust of the propellant.
  • the valve targeted by the invention is of the double feed type, each feed path being in communication with a tank, each of which contains one of the components.
  • the invention relates to the distribution of these components, not only as a mixture, but as desired, also individually.
  • the invention provides, in particular, for carrying out, before or after each use, purging the distribution system using propellant.
  • the dispenser of the invention can be used for the distribution of products of different nature, for example cosmetic or dermopharmaceutical products, household, technical, horticultural products, etc.
  • Document DE-A-29 16 699 describes a dispenser containing a product for two liquid components, separately, in a common housing and put under pressure using a propellant.
  • the container is fitted with a valve double feed mixer.
  • a first feeding route of the valve is in communication with a flexible pocket, disposed inside the container and filled with a first component.
  • the second feeding path of the valve communicates with a volume formed between the internal wall of the container and the outer wall of the pocket. In this volume are conditioned the second product and the propellant.
  • This dispenser allows, when the valve is actuated distribution, to distribute a mixture of the two components.
  • a shaving cream dispenser allowing to perform in a valve mixing the mixture of two liquids, initially separated, causing the heating of the cream is described in document US-A-3,326,416.
  • liquids can be hydrogen peroxide, and the other can contain a hypophosphite. The reaction of these liquids produces a decomposition exothermic of liquids, providing heat to components foaming and for dispensing a hot foaming mixture.
  • a dispenser capable of containing several components, is described in the document FR-A-2 133 112.
  • a dispensing valve actuated by a push button, is intended to selectively dispense one of said components, or a mixture consisting of the addition of different s constituents.
  • the valve as described, is not designed to perform the purge of the distribution system with a propellant gas, before or after use. In addition, such a valve cannot be produced industrially.
  • a a plurality of intake chambers is stacked, each chamber having a sealing means crossed by a common nozzle.
  • each intake chamber is set up communication with a corresponding tank comprising respectively one of the components, nor how these reservoirs are arranged in a body common exterior, and pressurized with propellant gas.
  • This distributor tries to avoid blockage of the valve, but does not warn clogging of the distribution system, nor does it plan to purge the latter by the propellant.
  • the document EP-A-0 709 305 describes a dispenser comprising a valve distribution for a single product, to be distributed in the form of a spray or foam, using a propellant, the valve being provided with an outlet orifice additional gas and a nozzle carrying a movable sealing gasket, in the rest position, the additional gas intake orifice.
  • the sprinkler when it is partially depressed, returns the seal to a position where it clears the hole of additional gas intake, and gas is sent into the distribution to purge it.
  • the nozzle when it is fully inserted, positions the movable joint in an area where a longitudinal groove and / or circular formed in the inner wall of the valve body allows admission of the product. Thus is carried out the distribution of a product / gas mixture.
  • This distributor is not designed for the distribution of two products, nor for the mixture of two products.
  • this distribution system requires actuation in three positions, two of which must be secured in a position between the rest position and the maximum sinking position. Such actuation is difficult for the user to perform because the two intermediate positions are hard to spot. Also, when the user's finger, pressing the button pusher, moves during distribution, it can occur, especially during a prolonged distribution, a change in the composition of the product in distribution course, which can have dire consequences.
  • the distribution system consists of a construction valve complex and bulky, occupying a large volume inside the distributor, volume that we would like to occupy by product and / or in particular, by propellant.
  • this valve to guarantee a reliable operation, there are four levels of tightness: a) - at where the valve stem emerges outward from the valve body; b) - to the entry of the first liquid into the valve body; c) - at the entrance to the second liquid in the valve body; and d) - between a flange of the rod and the wall internal of the valve body.
  • valve thus configured is one of the most delicate. Of plus, in certain areas, inside the valve body, for example by below the collar, product residue can accumulate, risking interfere with the correct functioning of the valve, or even cause blockage of it.
  • the invention aims to remedy all the above drawbacks, by proposing a distribution assembly comprising a valve, of simple construction, easy to use and reliable, allowing the user to choose one among several methods of distributing a product to several components.
  • the dispensing valve is with a single body defining an interior room.
  • the propellant can be chosen, in a conventional manner, from, in particular, hydrocarbons, hydrofluorocarbons and chlorofluorocarbons liquefiable, nitrogen, carbon dioxide, dimethyl ether, protoxide nitrogen, compressed air, or a mixture of these gases.
  • the inner container can be a reservoir flexible, for example formed by a flexible, compressible pocket or a container bellows. Any other retractable container, able to isolate the first component compared to the second can be used alternately.
  • a such an inner container is able to decrease in volume, as the consumption of the component it contains, in response to the pressure exerted by propellant gas placed in the outer enclosure.
  • a dip tube is planned. It is connected to the second supply port of the valve and extends substantially to the bottom of the outer container. This connection can be advantageously carried out by means of an adapter ring, mounted for example by tightening on the valve body and comprising a portion coming into engagement with one end of said dip tube.
  • the inner container in communication with said first supply port, is located substantially in alignment with the valve body.
  • the means for actuating the dispensing valve includes an elastic sealing means dividing the valve chamber into two parts, a first part being in communication with said first supply orifice and a second part being in communication with said second supply port, a passage being provided to establish a communication between said first and second parts of the chamber, when said actuating means is fully depressed. Furthermore, during actuation of the valve, said second part of the valve chamber is in communication with the means of distribution.
  • This arrangement has the advantage of being able to arrange the two orifices valve supply at a determined axial distance, so that the components are only mixed in the second part of the valve chamber.
  • This part of the chamber can be easily purged, and this in full, either to prevent the formation of dry residues, or to ejecting such dry residues formed by reaction of the components of the mixture during a prior distribution.
  • the axial level of the sealing means is chosen so, that in the valve closed position, said second part of the valve has a minimal or almost zero volume.
  • the axial level of the second supply orifice is chosen so that when the valve is in the first position, i.e. more precisely in the purge position, said second part of the valve chamber has as small a volume as possible. Also, from preferably, said second orifice is made in said second part of the valve chamber near the end opposite the first port feed. This arrangement allows the purge operation to be carried out in the best conditions.
  • the passage between the two parts of said chamber can be formed by at minus a longitudinal and / or circular groove, formed in an internal wall valve body. When said actuating means is fully depressed, this passage opens on either side of the sealing means in the first and second parts of the valve chamber.
  • the sealing means are formed of an annular seal.
  • the annular seal can be an added annular seal, for example of material elastomeric, such as Buna N® or Neoprene®. This joint is fixed on a periphery of the actuating means and is capable of sliding in sealed contact on the internal wall of the valve body, on either side of said passage.
  • the annular seal is an O-ring, but other suitable forms can be envisaged.
  • This annular seal can also be in the form of a cylindrical bead resulting integrally molded with the actuating means.
  • elastic return means are provided to ensure, in the valve rest position, closing the valve, and in the actuation, ensure by pushing, the selective distribution of components.
  • These elastic return means are advantageously formed, of a helical spring, in axial support against a bottom of the nozzle and produced, preferably metal.
  • maneuvering means are provided for actuating the valve.
  • they consist of a push button, crossed an evacuation passage constituting part of the distribution means which lead to a nozzle fitted with a dispensing orifice.
  • the internal container is rigid and not compressible.
  • said container contains, in addition to the first component, a propellant.
  • a dip tube is provided to extend the first opening feed substantially to the bottom of the inner container. In that case, use exclusively "head up” is recommended.
  • the purge of distribution means is carried out, in this case, in the “upside down” position by partial depression of the actuating means.
  • neither the first nor the second orifice supply pipes are not fitted with a dip tube.
  • the distribution of second component or a mixture of the components is made in position " upside down ".
  • the purging of the distribution means is carried out, in this case, in position "head up” by partial insertion of the means actuation.
  • An advantage of this valve is that there is no communication between the first and second supply ports, during the storage period.
  • the second component cannot therefore penetrate, inadvertently, in the inner container, and react, if necessary, with the first component, and vice versa.
  • the invention also relates to a method for the selective distribution of components contained in the dispenser which has just been described.

Simultaneously, the passage 15a is closed by the washer fixed elastic 12. Thus, in the rest position, the movable seal 11 ensures the tight separation between the containers 4 and 5, so that the liquid B, packaged in outer container 5, cannot pass into container interior 4 ( Figure 2), and vice versa. It should be noted, that the volume of the second part 6b of the valve chamber 6 is here almost zero.

In fact, it can be seen that the seal 11 is located opposite a zone 14 of the side wall 2b, having a larger internal section than the section of the rest of the valve body 2. In this way a "by -pass "is formed, allowing the component A to rise, from the first supply orifice 7, into the valve chamber 6.
