Definitions

  • the present invention relates to a multi-jet diffuser device for aerosol can and is particularly applicable to an aerosol can comprising a cap provided with such a diffuser.
  • the shape of the jet in the aerosol diffusion is of great importance, particularly in the case of paint aerosols where, in particular for aesthetic reasons or surface coverage to be painted, the user wishes to be able to adapt the jet according to the type work to be done.
  • more or less spread jets will be chosen, for example solid jets or flat jets or fogs more or less focused.
  • the document US 3,795,366 and the document US 3,711,030 describe a multi-jet diffuser device comprising a cap provided with a plurality of conduits each terminating in a nozzle placed directly on the valve of the container.
  • the document US 5,385,303 in accordance with the forms of the preamble of claim 1, discloses a multi-jet diffuser device having a hood provided with a single conduit.
  • the conduit connects the nozzle of the valve of the container to an opening in the body of the hood.
  • the device further comprises a coaxial ring with the cover on which nozzles are arranged and the rotation of the cover allows the jet to be selected by making the nozzles and the opening coincide.
  • the water intake opening disposed away from the nozzles does not provide sufficient sealing and accuracy for applications where aerosols are used.
  • the cover comprising the diffuser and the operating knob and is usually mounted forcibly on the top of the container which makes it difficult to remove and exchange.
  • the object of the present invention is to provide a multi-jet diffuser adapted for the diffusion of aerosols, of simple and inexpensive constitution, integrated into a hood fixed on an aerosol can.
  • the present invention relates to a multi-jet diffuser device, for aerosol dispensing spray of a product, comprising a cover, provided with a device for operating a nozzle of a valve of the bomb container.
  • aerosol and dispensing device said maneuvering and dispensing device comprising a conduit, provided with a first end, sealingly fitting on the nozzle, and provided with a second product dispensing end, characterized in that said second end opens into a product outlet housing and receives a plurality of selectable nozzle nozzles one by one.
  • the tips of the device according to the invention comprise a diffusion channel positioned facing the conduit and the housing has a complementary hollow shape of a rear part of the end pieces so as to seal around the connection between the leads and the channel.
  • the tips of the nozzles are arranged on a rotating wafer positioned on a support plate of the operating device, the support plate being provided with a plurality of housings comprising on the one hand, said outlet housing of the product and, on the other hand, blind housing for receiving unselected nozzle tips.
  • the device according to the invention for which the conduit connects seamlessly nozzle tips to the nozzle provides a seal compatible with the diffusion under a steady flow of finely atomized products and under significant pressures such as paints.
  • the multi-jet diffuser device 1 for aerosol dispensing spray of a product for example a liquid sprayed product such as a paint
  • a product for example a liquid sprayed product such as a paint
  • the device comprises a cover 3 and a device 4 for maneuvering and dispensing the product.
  • the maneuvering and dispensing device comprises a pusher 21, large control button, for driving a nozzle 5 of a valve 6 of a container 2 aerosol type known per se.
  • the maneuvering and dispensing device comprises a conduit 7 for conveying the product to a diffusion nozzle.
  • the conduit is provided with a first end 7a, sealingly fitting on the nozzle 5, and is provided with a second end 7b of product distribution.
  • the operating device is made in one piece with the cover, a spring hinge 18 for tilting the operating device and for actuating the valve while at least one breakable link 22, disposed at a opposite end of the hinge, relative to the maneuvering device protects the spray can against inadvertent operation of the device and, until it has been cut, guarantees to the buyer that the spray can was not yet used.
  • the cover is secured to the container 2 of the aerosol can by means of snap-fastening means 23, 23 'constituted by a first lip of the cap snapping onto a rim of the container and at least one lip portion snapping onto the skirt of the valve as shown in Figure 2B .
  • the snap on the skirt of the valve allows a more precise hold of the head relative to the position of the nozzle because the positioning tolerances of this skirt relative to the nozzle are more accurate than the positioning tolerances of the rim of the container. relative to this same nozzle and the fact that the skirt of the valve has a frank lower edge while the rim of the container is rounded.
  • the second end of the conduit 7 opens into a housing 8 of the product outlet and receiving a plurality of nozzles 9a, 9b, 9c of 10a, 10b, 10c diffusion nozzles can be selected one by one.
  • the end pieces 9a, 9b, 9c comprise a diffusion channel 11 positioned facing the duct 7, the housing 8 having a recessed shape complementary to a rear part of the end pieces 9a, 9b, 9c so as to provide a seal around the connection between the conduit 7 and the channel 11.
  • the end pieces may optionally be single end pieces, but according to a particularly advantageous embodiment of the invention, the nozzles provided with their end pieces are made on a rotary wafer 12, an example of which is shown in FIG. Figure 2A .
  • the rotary slab 12, on which are arranged the tips of the nozzles, is positioned on a support plate 13 of the operating device.
  • the support plate more particularly represented in Figures 7A to 7C is provided with a plurality of housings 8, 14 comprising on the one hand said outlet housing of the product 8 and, on the other hand, blind housing 14 for receiving unselected nozzle tips.
  • the wafer 12 is more particularly represented in figure 6 in the context of an embodiment comprising a ring 17 for retention of the wafer 12.
  • the wafer 12 has the nozzle outlets on its front face and the end pieces on its rear face, the end pieces 9 protruding from the rear face to be positioned in the housings carried by the support plate 13.
  • the plurality of nozzles 9a, 9b, 9c of nozzles and housings 8, 14 are arranged on a circular path 15 formed around an axis 16 of rotation of the rotary slab 12.
  • the circular path on the support plate is formed by an annular groove which receives a complementary annular ring 23 of the wafer and the axis 16 is a rod protruding from the face 13 to engage in a tubular housing of the wafer 12.
  • An inversion for which the rod is disposed on the rear face of the wafer is engaged in a housing of the support plate is of course conceivable within the scope of the invention.
  • the housings 8, 14 open into the groove forming the circular path 15.
  • a rotation of the wafer 12 makes it possible to move the end pieces from one housing to the other while climbing on the ramp formed by the circular path.
  • the device comprises means 19 for returning the wafer 12.
  • These means constituted here by one or more springs are adapted to apply the wafer 12 to the support plate 13, the wafer being provided with a rear edge 20 snapping on the support plate.
  • the selection of the nozzles 10a, 10b, 10c is achieved by the rotation of the wafer 12 and the passage of the end pieces 9a, 9b, 9c of a housing 8, 14 to the other.
  • the selection and positioning of the nozzles are precise, a good tactile sensation being given when the tips are engaged in the housing.
  • nozzles corresponding to different jets for example flat jet, solid jet and mist are provided as well as a tip 25 devoid of conduit, this nozzle corresponding to a closed position and safety device which, because of the good sealing achieved by the complementarity of the tips and housing, is a position for which no leakage of the product is possible.
  • maintaining the wafer on the support plate is obtained using an axis 11 ', formed on the rear face of the wafer and inserted into a housing of the support plate 13'.
  • the figure 3B corresponds to the embodiment of the figure 1 for which the diffuser device comprises clamping means, in the form of a ring 17 screwing on a peripheral edge of the support plate, adapted to apply the wafer 12 to the support plate 13.
  • the ring 17 and the wafer 12 are shown in FIG. figure 6 , a stud 24 positioned opposite the endpiece 25 without a conduit makes it possible, once the ring has de-tightened, to turn the wafer to make the mouthpiece of the selected nozzle coincide with the housing 8 comprising the outlet of the duct 7.
  • This embodiment allows, when the ring is tightened, to obtain optimum sealing of the spray device from the nozzle to the nozzle.
  • This screw device is however less easy to use than the embodiment with means for recalling the figure 3A because the ring must be loosened to turn the slab and then re-tighten it.
  • the support plate 13 is part of the actuating and dispensing device and is extended by a hinge element 18 connecting the maneuvering and dispensing device to the hood.
  • the operating device pivots around this hinge to actuate the nozzle of the valve and deliver the product.
  • the hood thus produced offers the possibility of offering several types of jets for the same container without increasing the size of the aerosol container, while maintaining the same safety of use as a single hood and nozzle spray because the Access to the valve is protected, for the pancake embodiment, by avoiding having to provide a plurality of nozzles that are at risk of being lost and providing a path without loss of pressure for the product between the valve and the nozzle.
