Definitions

  • the present invention relates to a manually operated sprayer for liquids of the type for fixing on the opening of a container.
  • Sprayers of the abovementioned type are already known and used for various purposes, such as, for example, homogeneous moistening, spray painting, spraying plants with liquid pesti­cides etc.
  • Such sprays usually comprise a pump which draws liquid from a container and sends it to a nebulizer nozzle by means of an appropriate duct.
  • a pump which draws liquid from a container and sends it to a nebulizer nozzle by means of an appropriate duct.
  • the object of the present invention is to carry out a manual sprayer which is both efficient and durable, having an automatic closing means to prevent the accidental escape of liquid from the container when the sprayer is at rest.
  • This object has been achieved with a sprayer capable of being fixed on the opening of a container.
  • This sprayer is provided with a channel extending from the said container to the surrounding air, the said channel having an external outlet which can be closed by a stopper integral with the operating lever of the pump.
  • the said stopper is positioned very close to the fulcrum of the lever.
  • the said fulcrum of the operating lever is positioned immediately below the stopper, which is positioned at the highest part of the sprayer when the latter is in the position for use.
  • the operating lever subjected to the action of a spring located in a pumping chamber, is put into communication with the liquid in the tank by a valve means described in the Italian utility model no. 24282 B/84.
  • the protective action against accidental escape of the liquid is preferably completed by a sealing strip between the neck of the container and the sprayer body.
  • One form of embodiment of a sprayer in accordance with the invention makes provision for a sealing strip in soft material at the vent channel outlet.
  • the sprayer illustrated in figures 1 and 2 is of a manually operated type having a body 2 whose extremity 3 is substantially cylindrical and is surrounded by a threaded ring nut 4 for screwing it to the neck of a liquid container.
  • a sealing strip 5 covers a flange 6, provided on the extremity 3, which carries out the counterboring for the neck of the container.
  • the body 2 contains a jacket 7 which forms a pumping chamber 27, housing a piston 8 and a spring 9.
  • the chamber 27 has at its entrance a notched hole 10.
  • the said hole is provided with a rubber occlusion member 11 which forms a valve means described in utility model no. 24282 B/84.
  • the chamber 27 is thus connected to a duct 12, extended by a suction pipe 13 which crosses the extremity 3 and is inserted into the container.
  • the said chamber 27 is connected at its exit with a duct 14 ending in a nebulizer nozzle 15 of the type already known.
  • the body 2 also contains a vent channel 16 extending from the entry 18 provided inside the extremity 3 of the body 2 to the outlet 17 positioned near the fulcrum 20 of the operating lever 19.
  • This fulcrum 20 is located in the upper part of the body 2 of the sprayer when the latter is in the operating position.
  • the piston 8 which slides into the chamber 27 is operated by the said lever 19 by means of two coaxial pins.
  • a stopper 23 is provided, which closes the outlet 17 of the channel 16 when the sprayer is at rest.
  • this stopper 23 which closes channel 16, acts as a sure prevention against an unwanted escape of the liquid when the sprayer 1 is at rest, no matter what position the container may be in.
