Definitions

  • the present invention relates to a dispenser device of a liquid, manually operated, for example by a trigger.
  • the present invention relates to a trigger-operated dispenser device able to dispense liquid according to at least two types of jet dispensed.
  • Such type of dispenser device in known in the trade as a "multipurpose" dispenser device.
  • the need to spray liquid in many types of jet is strongly felt, for example so as to obtain an almost continuous jet in a clearly specified direction, or more of a spray more widely distributed through the air.
  • the two jets are usually dispensed from two separate openings present on the nozzle.
  • the prior solutions have a number of drawbacks, due to the manufacturing complexity of the components of the device and their limited functionality. Often, in fact, the prior multipurpose dispenser devices present a discharge of liquid both from the active opening of the nozzle, corresponding to the desired jet, and from the other opening, on account of leakage between the components.
  • the purpose of the present invention is to satisfy the aforementioned requirements while at the same time overcoming the drawbacks of the prior solutions. Such purpose is achieved by a dispenser device made according to claim 1.
  • FIG. 1 shows a dispenser head of a dispenser device according to the present invention, fitted with a nozzle
  • figure 2 shows the head in figure 1 without the nozzle
  • FIG. 3 shows a cross-section view of a portion of the dispenser head in figure 1 ;
  • figure 4 shows an enlargement of the area IV in figure 2 ;
  • figure 5 shows the inside of the nozzle in figure 1 ;
  • FIG. 6a and 6b show the dispenser head in a first dispensing configuration
  • FIG. 7a and 7b show the dispenser head in a second dispensing configuration
