Definitions

  • the invention relates to a spray device, in particular for a system for dispensing a product provided with a push button.
  • the distribution system is intended to equip bottles used in perfumery, cosmetics or for pharmaceutical treatments.
  • this type of bottle contains a product which is returned by the distribution system comprising a device for withdrawing said product, said system being actuated for example by a push button to allow the product to be sprayed.
  • the sampling device comprises a pump or a manually actuated valve, for example by means of the push button.
  • Such push buttons are conventionally made in at least two parts, including an actuating body and a spray nozzle which are assembled to one another.
  • the nozzle generally comprises a swirl chamber provided with a dispensing orifice, as well as at least one supply channel for said chamber.
  • the sampling device withdraws the product from the vial through a dip tube, and pushes it inside the conduit arranged in the pusher, which is the actuating element of the sampling device.
  • This conduit opens into a so-called vortex chamber intended to make the liquid turn very quickly and therefore to give it speed and the effects of centrifugal force.
  • This vortex chamber is extended at its center by an outlet orifice through which the product escapes to the outside at high speed. Driven by this speed, and subjected to centrifugal forces, the liquid splits into droplets and forms an aerosol.
  • the size of the droplets from the vortex chamber depends in part on the force and speed with which the user operates the pump by pressing the push button with his finger, as the induced pressure depends on it.
  • one technology consists in using a vortex chamber of revolution.
  • the flow turns in the chamber in the form of a sheet which impacts itself after its exit through the distribution orifice.
  • This technology is used for non-viscous or low-viscosity products.
  • the impaction of the webs does not occur correctly, for example when the viscosity is greater than 150 mPa.s. This results in an excessively large size of the droplets and the cone of sprayed product is then of poor quality.
  • the steps make it possible to improve the impaction of the layers of product and to obtain droplets of small dimensions, and this with a viscous product.
  • the dimensions of the droplets are suitable in the major part of the sprayed cone, which makes it possible to obtain a cone of fine droplets of product.
  • a central area of the cone does not have the required requirements.
  • This central zone is located immediately downstream of the dispensing orifice in the direction of movement of the product, and extends in a substantially rectilinear manner.
  • the droplets have dimensions much larger than in the rest of the cone. It is common for a continuous jet in a central area to coexist with the peripheral droplets. In other words, the dimensions of the droplets are not uniform in the cone.
  • a user then receives on his hands or another part of his body, the product in the form of a continuous jet in the central zone, and this in a cone of fine droplets.
  • the experience of the product is therefore impaired. This is all the more true for a clientele whose expectations are often high.
  • this reflects a deplorable image of the product and its manufacturer despite the cosmetic qualities it conceals.
  • the invention aims to resolve this drawback.
  • This dispensing head has the advantage of eliminating the continuous jet which appears in the central zone. This is made possible by the combined action of the converging part provided with steps and a core forming at least one fluid path in which the product encounters obstacles. This is also made possible by the combined action of the converging part and a core provided with a step as well as a converging part and a core, both provided with steps.
  • the dispensing head is particularly advantageous when the product exhibits a non-Newtonian shear-thinning rheological behavior. This type of fluid becomes fluid as the shear rate increases. This type of product is widely used in the cosmetics industry.
  • the central zone then comprises droplets whose dimensions are substantially identical throughout the cone.
  • a dispensing head 1 in particular for a dispensing system (not shown) of a fluid product.
  • the distribution system comprises the distribution head 1 and a sampling device (not shown) provided with a supply tube inserted into a well 2 located in the distribution head 1.
  • the dispensing head 1 comprises a body 3.
  • the body 3 defines a bearing wall 4 located on an upper part thereof.
  • the support wall 4 allows the user to press the dispensing head 1 in order to spray the product.
  • the body 3 defines a housing 6.
  • the housing 6 is in fluid communication with the well 2. This fluid communication is carried out by means of an internal channel 27 formed in the body 3.
