Definitions

  • the present invention relates to a method of dispensing two components, in particular liquids, using a propellant, packaged separately from one another in the same distributor.
  • the invention also relates to a dispenser for selective dispensing of said components.
  • the dispenser according to the invention is of the "aerosol casing" type equipped with a dispensing valve, operable by means of a push-button and equipped with a dispensing system.
  • a push button has a dispensing orifice through which the component (s) leaves (s) the housing, under the thrust of the propellant.
  • the valve referred to by the invention is of the double feed type, each feed path being in communication with a reservoir, each of which contains one of the components.
  • the invention relates to the distribution of these components, not only in the form of a mixture, but to choose, also, individually.
  • the invention provides, in particular, to carry out, before or after each use, the purge of the distribution system, using the propellant gas.
  • the dispenser of the invention can be used for the distribution of products of different kinds, for example cosmetic or dermo-pharmaceutical products, household products, techniques, horticulturists, etc.
  • the document DE-A-29 16 699 discloses a dispenser containing a liquid two-component product, separately, in a common housing and pressurized with a propellant.
  • the can is equipped with a dual feed valve.
  • a first supply channel of the valve is in communication with a flexible bag, disposed inside the container and filled with a first component.
  • the second supply path of the valve communicates with a volume formed between the inner wall of the can and the outer wall of the bag. In this volume are conditioned the second product and the propellant gas.
  • This distributor makes it possible, when actuating the dispensing valve, to dispense a mixture of the two components.
  • a shaving cream dispenser making it possible to carry out in a mixing valve the mixture of two liquids, initially separated, causing the cream to overheat, is described in the document US-A-3,326,416 .
  • One of the liquids may be hydrogen peroxide, and the other may contain hypophosphite. The reaction of these liquids produces exothermic decomposition of the liquids, providing heat to foaming components and dispensing a hot foaming mixture.
  • a distributor able to contain several components, is described in the document FR-A-2 133 112 .
  • a dispensing valve operable by a push button, is provided for selectively distributing one of said components, or a mixture consisting of the addition of different components.
  • the valve as described, is not designed to bleed the dispensing system with a propellant before or after use. In addition, such a valve is not feasible industrially. Indeed, depending on the number of components to be dispensed, in this valve a plurality of inlet chambers is stacked, each chamber having a sealing means traversed by a common nozzle.
  • each inlet chamber is placed in communication with a corresponding tank respectively comprising one of the components, or how these tanks are arranged in a common outer body, and put under pressure using propellant.
  • This dispenser tries to avoid clogging the valve, but does not warn in any way case the closure of the distribution system, nor does it provide for the purge of the latter by the propellant.
  • the document EP-A-0 709 305 describes a dispenser comprising a dispensing valve for a single product, to be dispensed in the form of a spray or foam, using a propellant gas, the valve being provided with an additional gas intake orifice and a nozzle carrying a movable sealing gasket, in the rest position, the additional gas intake orifice.
  • the nozzle when partially depressed, returns the seal to a position where it releases the additional gas intake port, and gas is supplied to the dispensing system to purge it.
  • the nozzle during its maximum depression, positions the movable seal in an area where a longitudinal groove and / or circular formed in the inner wall of the valve body allows the admission of the product. Thus is carried out the distribution of a product / gas mixture.
  • This dispenser is not designed for dispensing two products, nor for mixing two products.
  • this distribution system requires actuation in three positions, two of which must be provided in a position between the rest position and the maximum depression position. Such actuation is difficult to perform by the user, because the two intermediate positions are difficult to identify. Also, when the finger of the user, pressing the push button, moves during distribution, it can occur, especially during extended distribution, a change in the composition of the product being dispensed, which can have disastrous consequences.
  • the dispensing system consists of a complex and bulky construction valve, occupying a large volume inside the dispenser volume that would be occupied by the product and / or in particular by propellant.
  • this valve to ensure reliable operation, it must provide a seal at four levels: a) - at the point where the valve stem emerges outwardly of the valve body; b) - to the inlet of the first liquid into the valve body; c) - at the inlet of the second liquid in the valve body; and d) - between a flange of the rod and the inner wall of the valve body.
  • valve thus configured is one of the most delicate.
  • product residues can accumulate, which may hinder the proper operation of the valve, or even cause clogging of the valve. -this.
  • the invention aims to overcome all the above disadvantages, by proposing a distribution assembly comprising a valve, of simple construction, easy to use and reliable operation, allowing the user to choose one of several modes distribution of a multi-component product.
  • the dispensing valve is single body defining an inner chamber.
  • the fact that the "mixing of components" mode occurs at the end of the stroke of the actuating means has the advantage that the mixing of the components is formed in the upper part of the valve chamber, and more specifically when the latter is at its maximum volume, above the seal, so that the mixture of components is carried out optimally.
  • the propellant may be chosen, in a conventional manner, from, among others, hydrocarbons, hydrofluorocarbons and liquefiable chlorofluorocarbons, nitrogen, carbon dioxide, dimethyl ether, nitrous oxide, compressed air, or a mixture of these gases.
  • the inner container may be a flexible reservoir, formed for example of a flexible pocket, compressible or a bellows container. Any other retractable container, able to isolate the first component relative to the second can be used alternately. In other words, such an inner container is able to decrease in volume, as and when consuming the component it contains, in response to the pressure exerted by propellant disposed in the outer enclosure.
  • a dip tube is provided. 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 performed, advantageously, by means of an adapter ring, mounted for example by clamping on the valve body and having a portion engaging 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 actuating means of the dispensing valve comprises an elastic sealing means dividing the valve chamber into two parts, a first part being in communication with said first supply port and a second part being in communication with said second feed port, a passage being provided for establishing communication between said first and second parts of the chamber, when said operating means is fully depressed. Furthermore, when actuating the valve, said second portion of the valve chamber is in communication with the dispensing means.
  • This arrangement has the advantage of arranging the two supply orifices of the valve at a determined axial distance, so that the mixing of the components is only carried out in the second part of the valve chamber. This portion of chamber can be easily purged, and this in full, so as either to prevent the formation of dry residues, or to eject 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 closed position of the valve, said second portion of the valve chamber has a minimum or almost zero volume.
  • the axial level of the second feed orifice is chosen so that, when the valve is in the first position, that is to say more precisely in the purge position, said second part of the valve chamber has a volume as small as possible.
  • said second port is formed in said second portion of the valve chamber near the end opposite the first supply port.
  • the passage between the two parts of said chamber may be formed by at least one longitudinal groove and / or circular, formed in an inner wall of the 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 may be an annular seal, for example of elastomeric material, such as Buna N ® or Neoprene ® . This seal is fixed on a periphery of the actuating means and is slidable in sealing contact on the inner 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 may also be in the form of a cylindrical bead integrally resulting from molding with the actuating means.
  • elastic return means are provided to ensure, in the rest position of the valve, the closure of the valve, and in the actuated position, ensure by depression, the selective distribution of components.
  • These elastic return means are formed, advantageously, a helical spring, in axial support against a bottom of the nozzle and preferably made of metal.
  • operating means are provided for actuating the valve.
  • they consist of a push button, traversed by a discharge passage constituting a portion of the dispensing means which open onto a nozzle equipped with a dispensing orifice.
  • the inner container is rigid and non-compressible.
  • said container contains, in addition to the first component, a propellant gas.
  • a dip tube is provided to extend the first feed port substantially to the bottom of the inner vessel. In this case, use exclusively “head up” is recommended. The purge of the dispensing means is effected, in this case, in "head down” position by partial depression of the actuating means.
  • neither the first nor the second feed port is provided with a dip tube.
  • the distribution of the second component or a mixture of components is performed in the "upside down” position.
  • the purge of the dispensing means is effected, in this case, in "head up” position by partial depression of the actuating means.
  • An advantage of this valve lies in the fact that there is no communication between the first and second supply ports during the storage period.
  • the second component can not inadvertently penetrate into the inner container, and react, if necessary, with the first component, and vice versa.
  • the invention also relates to a method of selective distribution of the components contained in the dispenser which has just been described.
  • pairs of components that can be packaged, one separate from the other, in the dispenser of the invention: a pair of two perfumes, a sunscreen and a product after sun, two hair dyes of different shades, two vitamins or two other cosmetic and / or dermo-pharmaceutical active ingredients, a foundation and a moisturizer, a deodorant and an antiperspirant, a hair conditioner and a film-forming agent, a compound permanent a reducing component and a fixing component, a hair dye composed of an oxidant and a dye, a two-component adhesive consisting of a monomer and a catalyst, etc.
