Definitions

  • Improved dispensing head and fluid dispensing device comprising such a head.
  • the present invention relates to an improved dispensing head and a fluid dispensing device comprising such a head.
  • Fluid product dispensing devices are well known and generally comprise a reservoir, a dispensing member, such as a pump or a valve, mounted on said reservoir, and a dispensing head enabling the pump to be actuated and thus to dispense.
  • a dispensing member such as a pump or a valve
  • the head is generally fixed to the mobile actuating rod of the pump and defines an expulsion channel leading to a dispensing orifice allowing the product to be dispensed.
  • Known dispensing heads can have certain disadvantages. Thus, it can prevent an unwanted or accidental removal or tearing of the pusher from its position mounted on the pump causing contamination of the product contained therein or in the tank.
  • the pusher being the last part of the device for dispensing a fluid product which is assembled, it is desirable to simplify this assembly step as much as possible.
  • the manufacturer of the product to be dispensed is generally not the manufacturer of the dispensing device, so that after filling the reservoir, the pump must first be mounted on the reservoir and then the dispensing head on the pump. Consequently, the pump and the dispensing head are generally delivered separately, and assembled at the manufacturer of the product II can in this case be difficult to avoid any risk of contamination during the assembly of the head on the pump, and this assembly requires complicated tools
  • dispensing heads in particular nasal type dispensing heads
  • the end of the head comprising the dispensing orifice is relatively far from the injection point of the mold, which makes it difficult to produce and the precision of the spraying profile.
  • the present invention aims to provide a dispensing head and a fluid dispensing device incorporating such a dispensing head which do not reproduce the aforementioned drawbacks.
  • the present mvention aims to provide a dispensing head which prevents any risk of contamination of the product.
  • the present invention also aims to provide such a dispensing head which is simple and inexpensive to manufacture and assemble.
  • Another object of the present invention is to provide such a dispensing head for which the final assembly of the fluid dispenser device is simplified, in particular when the manufacturer of the product to be dispensed is different from the manufacturer of the dispenser device.
  • the present invention also aims to provide a dispensing head preventing the tearing or removal thereof from the dispensing device after its assembly
  • the present invention also aims to provide such a dispensing head which can be easily cleaned without in any way affecting the functional part of the pump.
  • the present invention therefore relates to a dispensing head for a device for dispensing a fluid product, said dispensing head comprising an internal body defining a dispensing channel for the product, said channel ending in a dispensing orifice, and an external body. separate defining an actuating surface on which the use presses to actuate the dispensing device, said external body being fitted on said internal body, so that in the event of a tentaùve attachment or disassembly of said dispensing head, only said outer body is removable, said inner body remaining fixed to said dispensing device
  • the internal body comprises an external radial shoulder cooperating with an internal radial shoulder corresponding to the external body to define the assembled position of the head.
  • the external body is frictionally fitted onto the internal body
  • the head is produced in the form of a nasal plunger comprising an elongated frustoconical part intended to partially penetrate the nostril, and an enlarged part forming actuation surface
  • the external body incorporates the frustoconical part and the enlarged part
  • the internal body incorporates the truncated part and the external body incorporates the enlarged part.
  • the internal body comprises a hollow tubular member and a frustoconical skirt extending around said tubular member to form said frustoconical part, the free end of said skirt incorporating a radial shoulder to cooperate with the external body.
  • the free end of said frustoconical skirt has a sharp edge at its axial front surface
  • the internal body comprises fixing means, such as means for quetting, for fixing to said distribution device.
  • the present invention also relates to a device for dispensing a fluid product comprising a product reservoir, a dispensing member, such as a pump, comprising a dispensing head produced according to the present invention.
  • said internal body of the head is snapped onto the actuating rod of the pump, so that in the event of an attempt to remove the head, the internal body remains fixed to said pump, preventing any contamination of the Product contained in the reservoir
  • said internal body of the head comprises, at the level of the dispensing orifice, a shutter
  • FIG. 1 is a diagrammatic view in cross section of a fluid dispenser device incorporating a dispensing head according to the present invention , in the disassembled state
  • FIG. 2 is a view similar to that of FIG. 1 in the assembled state
  • FIG. 3 is a view similar to that of FIG. 2, showing an alternative embodiment of the invention
  • Figure 4 is a schematic cross-sectional view of another alternative embodiment of the present invention
  • the dispensing head comprises an internal body 10 defining a distribution channel 11 for the product.
  • Said internal body 10 is connected in the example shown in the figures to the actuating rod of the pump, preferably in leaktight manner
  • the expulsion channel 11 is terminated by a distribution orifice 12 which therefore forms part of the internal body 10
  • this internal body 10 can be pre-assembled on the pump 2, in particular at the manufacturer of said pump.
  • the head also comprises an external body 20 which defines an actuating surface 21, in this case a finger support zone in the examples shown in the drawings, on which the user presses to actuate the dispensing device.
  • the external body 20 is fitted onto the internal body 10, as can be seen in FIG. 2, preferably with friction, so that in the event of an attempt to loosen said dispensing head, only said external body 20 is removable while said internal body 10 remains fixed to said dispensing device, in this case to pump 2.
  • the internal body 10 can be fixed to the pump by a narrow friction fitting which provides good resistance or, as shown in FIG. 4, using a latching system 18 from the lower end of the internal body 10 on the actuating rod 3 of the pump 2
  • the internal body 10 comprises an external radial shoulder 19 which cooperates with an internal radial shoulder 29 conespond of the external body 20 to define the assembled position of the head as shown in Figures 2 and 3
  • the nasal pusher typically comprises an elongated frustoconical part which is intended to partially penetrate the narme, and an enlarged part which forms the actuation surface.
  • the external body 20 incorporates the frustoconical part 25 and the enlarged part 21.
  • the internal body 10 consists of a hollow tubular element 13, in which one may optionally have an internal nozzle 14, as shown in the figures, or even a shutter 40 as visible in FIG. 4.
  • the external body 20 is withdrawn while the body internal 10 remains fixed on the pump, thus preventing any contamination of the product contained in the tank or in the pump, while allowing easy cleaning of the pusher
  • FIG. 3 shows a variant in which the internal body 10 incorporates the truncated part 15 while the external body 20 incorporates the enlarged part 21 forming an actuation zone.
  • the internal body 10 comprises, in addition to the hollow tubular member 13, a frustoconical skirt 15 which extends around said tubular member 13 to form said frustoconical part.
  • the free end of said skirt 15, that is to say the lower end in the drawings comprises the radial shoulder 19 which cooperates with the external body 20, as well as a sharp edge 17 at the level of its axial frontal surface, to form a pungent anti-spill zone
  • FIG. 4 there is yet another variant, in which as mentioned previously, the internal body 10 is on the rod 3 of the pump 2, and said internal body 10 incorporates a shutter 40 disposed upstream of the orifice distribution 12, thus guaranteeing a perfect seal on all the product outlet path from the reservoir 1 to the dispensing orifice
  • the dispensing head according to the present invention therefore provides the following advantages - by the construction in two parts, it allows the removal of the external part only and maintains the internal part, which incorporates the distribution port, on the pump, avoiding thus any risk of contamination, re-heating, etc., while allowing easy and thorough cleaning of said dispensing head, - the production of the head in two parts makes it possible to preassemble the internal body on the pump at the pump manufacturer, which greatly facilitates the assembly at the manufacturer of the product to be distributed, especially if it is different from the manufacturer of the distribution device, the production of the head in two parts greatly facilitates the realization of the spray profile at the distribution device , the internal body can be produced in a tubular form in which it is very easy to provide such a profile, unlike t are nasal from the state of the art made in one piece, or, because of the necessary curvature at the end of the pusher, there are problems of wall thickness which make it difficult to produce said spraying profile , in the present case, these problems do not arise since the rounded shape of
