  • Applications in fields other than cosmetics can be envisaged, in particular in the field of adhesives.
  • the invention also relates to a container equipped with such a device for distribution and application.
  • Patent application FR-A-2 713 060 describes an applicator device for liquid comprising a container of the liquid to be applied to a surface to be treated and a dispensing dome connected to the container by a dispensing head, the dome dispenser being made of a porous material suitable for applying the liquid by simply rubbing the external face of the dome on the surface to be treated.
  • the container is a pressurized tank equipped with a distribution valve, the dome dispenser being carried by a support which constitutes an element of the head of distribution and is mechanically linked to a nozzle capable of cooperating with the valve to cause it to open under the action of a mechanical stress exerted on the dispensing dome.
  • Such a device is used in particular for products with a cold effect, effect obtained by the expansion of the propellant on the surface of the porous dome.
  • the product is a fatigue reliever for heavy legs, for which the cold effect is very positive by its vaso-restrictive effect of surface micro-capillaries, or a tensor for the bust, for which the cold effect is favorable by the tensor effect on the muscles and skin supporting the breasts.
  • Patent application EP-A- 0 133 369 describes a dispensing head on which mounted a toothbrush.
  • the valve is a side tilt valve operated by means of an attached push button, located on the side of the support toothbrush.

  • PCT application WO 95/03234 describes a distribution device offering several places to operate the dispensing valve.
  • the valve actuation is produced by tilting around an axis, organs distributed in several places on the periphery of the dispensing device, which mainly poses two problems.
  • a design implies a significant height of the push button, for mounting it, so that the actuating parts can come to bear on a rigid sleeve fitted on the valve stem.
  • the actuation of the valve causes a tilting of the outlet sleeve of the product, which causes a variable position of the product outlet.
  • Patent application DE 3 023 596 describes a device for applying a product creamy on a surface by means of a device fitted with a lateral tilting controlled by an actuating member which acts on a portion close to the applicator.
  • Such a device poses substantially the same problems than those described with reference to the PCT WO application device 95/03234, namely the need for a height distribution head important, and the tilting of the applicator in response to the actuation of the valve.
  • Such problems can be prohibitive for certain applications, especially for products whose application on sensitive surfaces in particular, must be located very precisely.
  • Such a device advantageously allows the use of modern industrial techniques for its realization, such as multi-material injection.

  • the applicator member consists of a cellular foam, with open cells or semi open.
  • cell material is used closed, the ascent of the product on the application surface is effected by micro channels produced in the applicator member, parallel to the axis of the container.
  • the applicator member is made of a material thermoplastic, by a bi-injection process, using the same material as the material of the flexible tube 13, which will be described more detailed below. However, a different material can be used.
  • the plate 8 has substantially at its center, an orifice 14, which advantageously, is partially closed by a protruding member 15, arranged so as to break the jet of liquid product delivered by the valve.

  • Connection can be made by any known means (bonding, breakdown, or mounting in slight compression, etc.). So the tube 13 advantageously makes a flexible connection between the valve stem and the support the application body. This flexible connection allows the tilting of the rod of valve 5, without inducing significant movement of the applicator member 10, in response to the movement of the valve stem 5. Furthermore, when the sleeve 13 is in slight compression, the seal is retained during actuation of the valve and the product outlet.

  • the assembly constituting the head is obtained by molding in one go, using injection presses multimaterials.
  • FIG. 3A illustrates the dispensing head as it emerges from the molding. Parts 16 and 20 are flat, and the constituent channels of the organ ring 22 can easily be removed from the mold. The slight taper of the skirt 7 further facilitates demoulding from the top of the area intended to receive the means valve actuation.
  • the flexible tube is centered on the axis of the head.
  • a double folding of the actuation means is carried out, on the one hand around axis 17, and on the other hand around axis 21.
  • the articulation 21 allows a range such that the angle ⁇ between the intermediate portion 20 and the support zone 16 is less than 90 °, so as to pass the member ring 22 under the support of the applicator member 10, and to be able to put it in engagement with the valve stem, without requiring too great a height between axis 17 and the support. This characteristic makes it possible to limit in a way substantial the height of the whole 1.
  • the annular member 22 has been raised from so as to be in contact with the lower end of the flexible sleeve 13.
  • the dispensing head is thus ready to be mounted by snapping onto a container 2, the annular member fitting onto the valve stem 5.
  • the different dimensions are calculated appropriately so that the flexible sleeve 13 is in slight compression so that sealing takes place at the interface between the sleeve 13 and the annular member 22.
  • FIG. 2 illustrates a variant of the mode. of embodiment of FIGS. 1A and 1B.
  • the sleeve flexible 13 is mounted tight on the emerging valve stem. Movement valve opening is transmitted to the valve stem via a portion 30, folded substantially at right angles to the intermediate portion 20.
  • the valve opening force is applied substantially at the level of the valve, by means of the portion 30.
  • This portion 30 causes the rod to tilt valve via the flexible sleeve 13.
  • a third axis could be provided in the vicinity of the tilting of the rod, so as to slightly delay the tilting of the rod relative to the action of the user on the support zone of the means actuation. This could constitute "security” by avoiding certain unintentional valve actuations.
