Definitions

  • the present invention relates to a nozzle for dispensing product, especially foam, for pressurized container with valve.
  • Such dispensing tips are already known to be used for example on containers containing holding foams capillary.
  • dispensing tips have a channel inside which conveys the conditioned product into the container from the valve of the latter to a dispensing orifice opening out towards the outside of the nozzle.
  • this channel can remain inside the canal, after delivery of a dose of product, a small and nevertheless significant amount of this product.
  • the dispensing opening is generally directed towards the high in the rest position of the container, the valve then being at the bottom of the canal, the product thus deposited on the walls of the canal ends by flowing and accumulates in the lower part of the latter, which can in the long term close it in its narrowest parts, especially in the vicinity of the container valve.
  • a foam dispenser tip shaving device comprising a pusher arranged for sucking the foam contained in an outlet duct leading to the orifice of distribution during its movement back to its position of rest, in order to avoid the appearance of an overflow of foam at the outside of the nozzle after use.
  • the latter presents a internal cup to collect the suctioned foam, in the center of which opens the outlet orifice of a valve pipe by which foam is distributed inside the nozzle when a pressure is exerted on the pusher.
  • This tip is not suitable for distribute a hair holding foam containing substances which harden as they dry because they would form a deposit in said cup which would seal the valve tubing.
  • FR-A-2640942 has proposed a nozzle for dispensing food product, especially coffee, tea or chocolate drink soluble, comprising a pusher defining inside the end piece a chamber of variable volume, so that a movement of return of the pusher to its rest position sucks up the contained product in the outlet pipe and prevents any product remaining at the level of the dispensing orifice.
  • the pusher closes the outlet duct in the rest position.
  • the food product contained in the mouthpiece distributor is thus isolated inside the latter when the pusher is at rest and cannot dry quickly.
  • Such a tip distributor has a relatively complex structure.
  • the present invention aims to provide a dispensing tip simple in construction and whose channel does not present the risk of seal by accumulation of product whatever the product conditioned, in particular hair holding foams, which contain substances which harden on drying, e.g. resins.
  • the subject of the present invention is a dispensing nozzle for product for pressurized container with valve, comprising a rod maneuver provided with a channel extending freely from a valve of the container up to a dispensing orifice opening to the outside of the nozzle, characterized by the fact that the valve operating rod has at least one collection cavity located in the rest position of the container, below areas of the channel in which the product is likely to be retained when it circulates in the canal, so that the product thus retained flows and accumulates in this collection cavity when the container is later left to rest.
  • the dispensing nozzle according to the invention makes it possible to avoid that the product deposited in the channel does not flow and accumulates in its narrowest parts, especially near the valve of the container.
  • the collection cavity according to the invention has for function of collecting the product flowing along the walls of the channel.
  • this cavity is dimensioned so such that it can contain enough product to never be filled until the contents of the container are used up.
  • the quantity of product likely to be retained in the channel and build up in said collection cavity depends including the nature of the product, the frequency of use and the capacity of the container, the shape of the channel and the type of orifice which is placed at the end of the channel.
  • the collection cavity is located in a bent part of the canal, at the right of a vertical branch of the latter leading to the orifice of distribution.
  • the collection cavity is located in the lower part of the canal, at a level lower than the valve orifice. So, like a siphon, the collection cavity collects product flows, avoiding that the latter does not accumulate at the level of the valve orifice.
  • the cavity extends in the vicinity of the dispensing orifice.
  • This embodiment is particularly indicated in the case where the dispensing orifice is fitted with a grid or spark gap, which constitutes a privileged area of product retention.
  • the collecting cavity is located in the lower part of the inclined branch of the canal.
  • Another subject of the invention is the use of a nozzle. above in a valve container for dispensing a product, in particular a capillary holding foam, containing substances which harden as it dries.
  • the dispensing nozzle has a collar 1 for mounting on a pressurized container, not shown.
  • a blade 2 is subject to this flange 1 by means of a articulation zone 3 which is in fact a thinned part of the blade 2.
  • the blade 2 is integral with an operating rod 4 a, 4 b , which is therefore movable in rotation around the articulation zone 3 at a very small angle of rotation, so that the movement of the operating rod can be likened to an axial translational movement.
  • the operating rod is formed in the example described by the assembly of two parts 4 a and 4 b .
  • a push button 5 exerts pressure on the operating rod 4 a , 4 b to push it into a valve body 6 where it is pushed in the opposite direction by a spring 7.
  • the valve body 6 has an opening 8 a into which the operating rod penetrates and, opposite this opening 8 a , a mouth 8 b intended to receive a tube (not shown) immersed in the packaged product.
  • a channel 9 is provided inside the operating rod 4 a , 4 b .
  • the end of the channel 9 located on the side of the container has a passage 10 of small diameter.
  • the spring 7 pushes the operating rod 4 a , 4 b upwards, by resting on a flange 11 which closes the orifice 8 a of the valve body 6.
  • the passage 10 is then closed and the product remains in the pressurized container, not shown.
  • the operating rod 4 a , 4 b descends into the valve body 6 and places the orifice 10 in communication with the interior of the valve body.
  • the product can then enter through passage 10 into the channel 9 where it is routed to a distribution orifice 12.
  • the channel 9 is essentially vertical.
  • channel 9 comprises, in the embodiment of Figure 1, a collection cavity 13 located to the right of the large vertical upper part of the canal 9.
  • a cavity of collection 14 is provided in the lower part of channel 9, in a block 15 which serves as a guide for the spring 7.
  • FIG. 3 corresponds to the case where the dispensing orifice 12 is provided with a grid or spark gap not represented.
  • Such a grid or spark gap constitutes a privileged area retention of the packaged product.
  • An annular collection cavity 16 is provided around the upper end of channel 9 to collect the retained product through the grid of the dispensing orifice 12.
  • the channel 9 has a branch 9 a inclined.
  • a recovery cavity 17 is provided at the lower part of this inclined branch 9 a to collect the product flowing from the dispensing orifice 12 and along the walls of this inclined branch 9 a of the channel.
