Definitions

  • the invention relates to a push button for a dispensing system of a product under pressure, as well as such a dispensing system.
  • the dispensing system is intended to equip bottles used in perfumery, in cosmetics or for pharmaceutical treatments.
  • this type of bottle contains a liquid product which is returned by a dispensing system comprising a device for sampling under pressure of said product, said system being actuated by a push button to allow the product to be sprayed.
  • the sampling device comprises a pump or a manually operated valve via the push button.
  • Such push buttons are conventionally made in two parts: an actuating body and a spray nozzle of the product which are associated with each other to form a swirl assembly comprising a vortex chamber provided with a dispensing orifice and at least one supply channel of said chamber.
  • the feed channels can lead tangentially into the vortex chamber which is cylindrical of revolution to rotate the product very quickly, the dispensing orifice having a reduced diameter relative to that of said chamber so that the rotating product escapes through said orifice with a speed sufficient to split into droplets forming the aerosol.
  • the aerosol is composed of droplets of very different sizes.
  • the aerosol is commonly constituted by droplets of diameter between 5 ⁇ m and 300 ⁇ m.
  • the large droplets are heavier than the smaller ones and follow a different distribution path, which can cause indelible stains in the case of perfumes.
  • small droplets are the lightest and can be inhaled, which may be the goal in the case of drugs, but this can be an undesirable effect in the case of toxic products.
  • the place of application for example within the respiratory system, depends on the size of the droplets, and the large disparity in size distorts the treatment.
  • the size of the droplets from a vortex chamber depends in part on the force and speed with which the user actuates the pump pressing the push button with his finger, because the induced pressure depends on it.
  • the aerosol tends to be hollow with a substantially conical envelope which consists of the majority of droplets while there is little inside the cone.
  • this distribution of droplets can be harmful for dermal applications.
