Definitions

  • the present invention relates to a product dispensing device attached to the neck of a tank.
  • a drug delivery device in the form of a spray comprising a pump, such as a nasal spray device.
  • a dispensing device ensures the greatest possible seal (to liquids, gases, bacteria) between the outside and the inside of the device or reservoir, that is to say all along the path traveled by the product, to prevent bacteria from developing and contaminate the product.
  • Such devices are often referred to as "preservative free” devices. They may be provided with a dispensing nozzle attached to the pump, comprising a non-return valve disposed just before the dispensing orifice of the product and preventing bacteria from developing in the dispensing tip. Such an end piece is for example described in the publication FR 2887232 .
  • the present invention is intended in particular to provide a dispensing device in which the risk of developing bacteria is even more reduced.
  • the device is attached to the tank by means of hooking means, which provide a snap-fit shape activated by the clamp, and which constitute a method of fixing almost unmountable by the user, unlike a fastening by screwing.
  • This type of attachment is similar to a "snap-on" fixation.
  • the fastener also ensures retention of the dispensing nozzle on the device, thanks to its outer ring, which ensures that this nozzle can not be removed from the pump on which it is reported, even with a consequent force.
  • the dispensing nozzle is thus retained in two distinct ways on the device: on the one hand it is fixed on the pump, being attached to a movable part of the pump, for example by clamping, on the other hand it is retained by the outer ring of the nozzle, which thus prevents tearing of the nozzle attached to the pump.
  • the dispensing device is a module that carries all the distribution elements to report on the reservoir, in particular the pump, the dispensing tip and the protective cap. These elements thus form a module, pre-assembled thanks to the fastener.

Indeed, the hood being carried by the clamp, a support on the cover can be directly transmitted to the collar.
  • This assembly in one step is interesting because the inside of the dispensing device is protected by the cover and is therefore not in contact with the outside, which avoids any risk of contamination during final assembly.
  • This embodiment allows the dosing device to be manufactured in a different from the one in which it is assembled on the bottle without incurring the risk of particulate pollution.
