Definitions

  • the present invention relates to a device for dispensing and packaging a product, this device comprising a container for storing under pressure said product, provided with a valve with control rod, and a porous applicator made of sintered or similar material, having a external application surface intended to come into contact with the skin of the user to dispense product.
  • the comfort with the use of such a device depends in particular on the impression of freshness provided to the user during contact of the applicator with the skin, due in part to the fact that the product has cooled during the trigger which accompanies its exit from the pressurized container. It is moreover desirable to avoid that in the event of prolonged use of the device, droplets of product do not flow onto the container or onto the user's hands.
  • the cup of the device described in FR-A-2 713 060 has a depression capable of collecting an excess of liquid ejected by the control rod and substantially radial channels are formed between the internal face of the cup and the internal face of the applicator to ensure good distribution of the product to be distributed and uniformly supply the external application surface.
  • a jet breaker is made for the same purpose opposite the end of the internal channel of the nozzle.
  • a device of the type described in FR-A-2 713 060 is of relatively complex construction.
  • the object of the invention is to propose a new distribution and packaging device which is of construction simplified while being as comfortable to use as known devices.
  • the applicator has a central blind bore allowing it to be fixed directly to the control rod, the depth of this bore being chosen so as to inject the product in situ into the applicator with diffusion substantially axial of the product towards the center of said external application surface.
  • the external application surface is aspherical, generally convex towards the outside, and the dome is arranged so that the product diffuses in the applicator according to a diffusion cone inscribed in a volume delimited by an extreme cone whose generator rests on the periphery of the external application surface and whose apex is located on the axis of the control rod, inside the latter.
  • the lateral surface of the applicator extending radially outwards and downwards said external application surface does not receive any product for a certain period of time following the opening of the valve and in the event prolonged use of the device, causing the appearance of droplets of product at the center of the external application surface, the lateral surface of the applicator, not saturated with product, remains capable of absorbing said droplets when they leave by gravity the center of the external application surface, which prevents the product from flowing onto the container or the user's hands.
  • the concentration of the product in the center of the applicator allows the user, holding the applicator by its periphery (which remains for a certain period of time without direct supply of product after opening the valve as explained above. ) actuate the valve to test the device without risking having your fingers wet by the product.
  • annular groove is provided to further improve the channeling of the product towards the center of the external application surface by delaying the diffusion of the product towards the lateral surface of the applicator.
  • the presence of an annular groove open towards the container, on the underside of the applicator, is also advantageous when the control rod is tiltable and the valve used is a valve with opening by lateral thrust on the control rod, because it increases the maximum angular movement of the applicator before contact with the container.
  • FIG. 1 shows a device 1 for dispensing and packaging a liquid product such as a deodorant, in accordance with a first embodiment of the invention.
  • This device 1 comprises a container 2, known in itself, of the aerosol can type, symmetrical in revolution in the embodiment described around a longitudinal axis X.
  • the container 2 has an upper end in the shape of a warhead, provided with an annular groove 3 intended for the latching of a annular bead 4 of a protective cover 5 shaped to cover the upper end of the container 2 in the absence of use of the device.
  • the container 2 comprises a valve known in itself of which we can see in Figure 1 that the fixing means on the container (in the embodiment described in the form of a cup 6 set in an opening of the container 2, and the control rod 7.
  • the valve fitted to the container 2 is of the opening-push-in type of the control rod 7.
  • the control rod 7 is of axis X and it is traversed internally and axially by a product passage channel and it is forcibly engaged at its emerging end in a blind bore 8 of an applicator 9 consisting of a porous block obtained by sintering polyethylene microspheres.
  • the applicator 9 is soft to the touch and slightly compressible, deforming very little or not when it is placed in contact with the skin of the user.
  • the applicator 9 is delimited above by an external application surface 10 intended to come into contact with the skin of the user, having in the example of embodiment described an aspherical shape, slightly curved, convex towards the outside.
  • the surface 10 is connected (without forming a projecting edge) by its circumference, circular centered on the axis X, to a lateral surface 11, cylindrical of revolution in the embodiment described around the axis X.
  • the applicator 9 is delimited below by a flat surface 12 perpendicular to the axis X, in the center of which opens the bore 8. The lower end of the latter is chamfered to define a conical mouthpiece 13 facilitating the insertion of the control rod 7 in the hole 8 when mounting the applicator 9 on the latter.
  • the insertion length l of the control rod 7 in the applicator 9, that is to say the depth of the blind bore 8 in the embodiment described, is chosen so as to that the product leaving the control rod 7 is injected in situ into the applicator 9 and diffuses mainly axially towards the external application surface 10.
  • the distance l is greater than or equal to half the external diameter d of the control rod 7 and the product diffuses into the applicator 9 according to a diffusion cone D inscribed in a volume delimited by a cone 14 resting on the periphery of the external application surface 10 and the apex of which is situated on the axis X in the vicinity of the upper end edge of the control rod 7
  • the product ejected by the latter diffuses mainly towards the top of the external application surface 10, that is to say towards its central region, and does not reach the lateral region of the applicator 9 until later. , after a certain period of time.
  • the lateral surface 11 therefore remains product-free and retains an entire absorption capacity to absorb possible drops of liquid having pearled at the top of the external application surface 10 (the device 1 being optionally inclined relative to the vertical) and having flowed by gravity onto the external surface of the applicator 9. This is to prevent drops of product from flowing over the entire height of the side wall 11 and do not fall onto the container or onto the user's hands, which guarantees comfortable use of the device 1 in all circumstances.
  • FIG. 2 There is shown in Figure 2 a device 1 'according to a second embodiment of the invention. The same reference signs have been kept for the elements identical to those of the previous embodiment.
  • the annular groove 15 has a flared section towards the container and a flat bottom, as shown in FIG.
  • the mouth of the blind bore 8 is situated substantially in the same plane as the radially external lower edge 18 of the applicator 9.
  • the cover 5 is removed and the applicator 9 is passed over the region of skin over which it is desired to distribute the product.
  • the applicator is lightly pressed so as to depress the control rod 7 and cause the valve to open.
  • the friction in contact with the skin is sufficient to cause the applicator 9 ′ to topple and open the valve.
