Definitions

  • the present invention relates to a product distributor liquids or pasty.
  • the withdrawal of the product from the tank is carried out by means of a pump having an inlet valve which defines, with the exhaust valve, a chamber inside the pump body.
  • This room is likely to be put first in depression to draw product into the tank then pressurized to expel said product outside.
  • the object of the present invention is to solve the problems previous technical and economic by looking for a device whose the number of constituent parts is reduced and which is capable of ensuring both simple and waterproof packaging, as well as distribution reliable product.
  • the external face of said piston has a socket delimiting with the internal side wall of the tank a peripheral space in which the part is engaged lower side of the nozzle.
  • said tip consists of a part of a distributor head provided with said internal evacuation duct communicating at its lower part with the nozzle tube and extending, on the other hand, to the tank by a side skirt.
  • the dispenser in addition, provision is made for the dispenser to include a cover. removable intended to cap the end piece.
  • This cover is fitted so telescopic on the upper part of the inner jacket by being flush the external side wall of the tank. Its internal side wall is in additionally provided with a longitudinal groove forming a vent.
  • said tip is movable axially and relatively to the piston being returned to position away by a spring resting on the external face of the piston.
  • the spray tube is then formed of a hollow rod engaged with sliding way in the axial duct of the piston and whose end bottom protrudes inside the tank regardless of position from the mouthpiece.
  • the lower end of the tube nozzle is closed by a full base of enlarged section intended for come into watertight support when the tip is brought against the rim internal of the axial duct thereby forming the exhaust valve.
  • said intake port opens laterally to the lower end of the spray tube, on either side of its axis central.
  • said axial duct is ends at its outer end with a pierced hemispherical cap a central ejection orifice with elastically deformable edges intended to be closed in a closed position by an integral axial finger of the nozzle and forming an exhaust valve.
  • the spray tube is then fitted onto the axial duct and takes support by its lower edge on the external face of the piston.
  • the nozzle tube is fitted in the axial duct and is supported by a peripheral shoulder on the external face of the piston.
  • the internal conduit tip outlet is provided with the exhaust valve which is then consisting of a rod carrying on the one hand at its outer end a cup with lateral flank forming a peripheral lip elastically deformable and, on the other hand, at its inner end a fixing crosspiece in said exhaust duct.
  • the piston has a substantially bell-shaped cross section; with a peripheral lip sealingly against the internal wall of the tank.
  • the axial duct of the piston projects towards the inside of the tank and the bottom of the tank has a profile complementary to that of the internal face of the piston to ensure complete evacuation of the product.
  • Another object of the invention is a packaging process of the product inside the previous dispenser, characterized in that fills the product tank and, at the same time, the system is mounted obturation and sampling by fixing the tip on the piston with, the if necessary, an intermediate spring, then introducing the assembly thus formed in the shirt until the flange of the end piece comes abutting from the inside against the shoulder of the shirt, and covering the end piece with a cover, then we assemble the shutter system and sampling from the tank by sliding the jacket in contact of the internal wall of the tank with radial clamping.
  • the dispenser of the invention ensures both perfectly sealed packaging and reliable product ejection with technically simple and therefore economical means.
  • this distributor presents no risk of defusing since it is the tank which is itself put under pressure.
  • the sample is taken at the request of the user and, continuously, without any dosage of the product.
  • the quantity of product delivered therefore only depends on the duration and bearing force on the end piece forming a pusher.
  • the dispenser shown in Figures 1a and 1b includes a product tank.
  • the reservoir 1 is surmounted by a nozzle 2 provided with an internal discharge duct 2a.
  • the means of taking the product from the reservoir 1 include a piston 3 housed inside the tank 1.
  • the piston 3 is crossed by an axial duct 30 connected to a nozzle tube 4 which, in this embodiment, consists of a hollow rod.
  • the piston 3 is axially movable in tank 1 by pressing on end piece 2.
  • the lower end 4a of the tube 4 defines, with the axial duct 30, an inlet 40, while its upper end 4b is provided with an ejection orifice 41 and is integral with the nozzle 2.
  • the lower end 4a of the nozzle tube 4 is closed by a base solid 42 whose cross section is wider than that of the axial duct 30.
  • the base 42 is intended to come into watertight support when closing against the internal rim of the axial duct 30 thereby forming the valve exhaust.
  • the tank 1 is lined with an internal side jacket 10 in radial tightening.
  • the axial duct 30 projects towards the inside of the tank 1 and the bottom 1b of said tank has a profile complementary to that of the internal face 3b of the piston 3 to ensure complete evacuation of the product.
  • the piston 3 preferably has a substantially bell-shaped section. with a peripheral lip 32, folded inwards from the tank 1 and sealingly against its internal wall or that of the jacket 10.
  • the piston 3 slides in the tank 1 continuously and at uniform speed. This displacement is accompanied scraping of the internal wall of the tank 1 or of the jacket 10 by the lip 32.
  • the end piece 2 therefore forms a manual pusher which is supported, here via a spring 5, on the external face 3a of the piston 3 to put the tank 1 under pressure.
  • the end piece 2 consists, on the one hand, of a head distributor 20 provided with the internal evacuation duct 2a which communicates at its lower part with the ejection orifice 41 of the tube nozzle 4.

  • the nozzle tube 4 slides in the axial duct 30 to release the intake port 40 carried by its lower end 4a and opening laterally on the tube 4 on the and on the other side of the central axis.
  • the spring 5 reaches a plateau of compression (depending on its stiffness)
  • the force is transmitted indirectly, via the spring 5, to the piston 3 which then moves down to compress the product.
  • the latter under the effect of pressure, then escapes through the inlet 40, then by the nozzle tube 4 to the discharge duct 2a.
  • the spring 5 recalls it in the high position by driving the raising of the nozzle tube 4 and the sealed support of the base 42 against the inner lower edge of the axial duct 30.
  • the tank 1 is then closed again and the product is isolated from outside.
  • the heights respective of the skirt 21 and of the sleeve 31, as well as the stiffness of the spring 5 are determined with respect to each other so that the upper edge of the sleeve 31 of the piston 3 comes into abutment stop directly against the head 20 of the nozzle 2 or, according to another variant (not shown), that the lower edge of the skirt 21 comes in support stop directly against the external face 3a of the piston 3, before that the spring 5 has not reached its compression level.
  • This configuration with direct support on piston 3 limits the stroke of the nozzle 2 and leads to a more frank evacuation of the product.
  • tank 1 and its jacket 10 a transparent material so that you can constantly observe the remaining product level. End piece 2 sinks without possibility of return to its initial position in tank 1 during distributions successive of product.
