Definitions

  • This invention relates to apparatus for dispensing a fine spray of liquid particles and more especially, but not exclusively, to liquid dispensers known as air brushes.
  • My British Patent No: GB-A-2245196 discloses apparatus for dispensing a fine spray of liquid particles which comprises a manually operated pump connected to supply air under pressure directly to a nozzle so positioned that air leaving the nozzle is directed onto and over a nib of a pen-like container releasably supported within a holder with the nib of the pen-like container in close proximity to the nozzle outlet to cause liquid from the pen to be dispensed as a fine particulate spray in air.
  • GB-A-2245196 discloses a foot operated pump connected by a flexible hose to a hand held nozzle including a holder for supporting a felt-tipped pen.
  • US-A-2538416 discloses an atomiser including a flexible hand-operated bulb connected to a flange forming part of a cap of a container of fluid to be atomised.
  • the flange includes a neck portion which protrudes into an open end of the bulb and is formed with an outwardly extending stop which located behind an internal surface of an inwardly extending tip of the bulb.
  • US-A-4845 516 discloses a pen exchange mechanism by which a plurality of pen chuck mechanisms holding pens on a carriage are disposed.
  • the present invention sets out to provide a simplified dispenser including a hand operated pump connected directly to a hand held nozzle without the need for a flexible hose.
  • the present invention also provides a dispenser in which the hand operated pump is securely connected to the nozzle to prevent displacement thereof during use.
  • apparatus for dispensing a fine spray of liquid particles comprising a hand operated flexible bulb formed with an open-ended neck which locates over the inlet end of a nozzle positioned to direct air over the inlet end of a nozzle positioned to direct air under pressure from the flexible bulb onto and over the nib of a pen releasably supported within a holder with the nib of the pen in close proximity to the outlet of the nozzle
  • the apparatus being characterised in that the inner surface of the neck of the flexible bulb includes an inwardly extending annular rib which, on assembly of the bulb to the nozzle, seats behind an outwardly extending annular step of an inclined section of the nozzle, located at or towards the said inlet end of the nozzle and in that the inlet end of the nozzle over which the neck of the bulb seats is formed with a second inclined section which terminates in an annular step.
  • the nozzle preferably includes a locating surface against which a shoulder of the pen adjacent its nib abuts in use to ensure correct location of the nib with respect to the nozzle outlet.
  • the nozzle and the pen may, in use of the apparatus, be retained within discrete channels of a separable holder, the channels being mutually inclined so that compressed air leaving the nozzle flows directly onto and over the nib of the pen.
  • the channel for retaining the pen may be defined by a sleeve releasably secured to the holder. More than one such sleeve may be provided to enable pens having a variety of diameters and cross-sections to be retained by the holder.
  • the channel for retaining the pen which may be the sleeve releasably secured to the holder, may be provided with internal flanges or shoulders for example which may be of a flexible and/or resilient nature, and which may be so arranged and configured as to enable pens having a variety of diameters and cross section to be retained therein.
  • the bulb may be produced from a flexible material such as rubber which can be squeezed or otherwise deformed to expel air under pressure therefrom.
  • the liquid may be a colourant such as ink or an edible food colourant and the liquid source may comprise a conventional ink pen or a felt tipped marker.
  • the air brush illustrated in Figures 1 and 2 comprises a hand pump 1 in the form of a flexible bulb of, for example, rubber connected to a nozzle 2 retained within a first channel 3 of a plastics holder 4.
  • the holder 4 includes a second channel 5 within which is removably mounted a sleeve 6.
  • the sleeve is retained in place by a suitable screw fixing 7.
  • a felt-tipped pen 8 Positioned within the sleeve 6 is a felt-tipped pen 8.
  • the channels 3,5 are mutually inclined so that the nib 9 of the pen 8 is positioned in close proximity to the nozzle outlet.
  • the pen shoulder 11 adjacent the nib 9 is positioned against a step 10 for location purposes.
  • the holder 4 is designed to be held a specified distance away from the article on which a fine spray of particles is to be applied. Operation of the hand pump 1 causes air under pressure to flow directly through the nozzle 2. As this compressed air passes over the nib 9 of the pen, a fine dispersion of particles is produced.
  • the end 12 of the nozzle 2 over which the open end 14 of the bulb 1 seats includes, in sequence, an inclined section 15 terminating in an upstanding annular step 16, a second inclined section 17 terminating in an annular step 18, and an annular end stop 19.
  • the bulb 1 includes a neck 20 of a length substantially equal to the length of the nozzle end 12 and an inwardly extending annular rib 21 at the junction of the neck 20 and the main part of the bulb 1.
  • the neck 20 is forced over the inclined sections 15,17 of the nozzle until the end of the neck seats adjacent the end stop 19.
  • the annular step 16 is positioned just behind the annular rib 21 of the bulb and ensures that, despite a build up of pressure within the bulb or the nozzle, the bulb is retained securely on the nozzle. Without the rib 21 and step 16, it has been found that the nozzle can be ejected from the bulb if the bulb is squeezed too tightly or rapidly.
  • the pen 8 may comprise a felt-tipped pen. Alternatively, it may comprise a cartridge containing a technical drawing pen or the nib of a conventional pen. Alternatively, edible food colourants, ink-based acrylic and emulsified paints may be dispensed by means of the apparatus. A selection of sleeves 6 may be provided to enable a variety of different liquid sources to be employed.
