Liquid dispensing apparatus

A hand held apparatus for producing a spray pattern,

• comprising:
• a frame including an air nozzle and a pen holder, each of said air nozzle and pen holder having a longitudinal axis, said frame including a substantially rigid connecting portion for holding said air nozzle and said pen holder with their respective longitudinal axes at a fixed angular separation,
• said air nozzle having a first wider end configured to direct air through an airway passage at a second narrower end, said second end being truncated to form an inclined face having a slope of between 20 and 60 degrees to said longitudinal axis of said air nozzle and an angled opening,
• said slope being generally parallel to said longitudinal axis of said pen,
• said angled opening extending through said flat inclined face such that said angled opening is in fluid communication with said airway passage of said air nozzle;
• and
• a pen disposed in said pen holder, said pen having a nib,
• wherein an exposed surface of said nib is held in close proximity to said angled opening of said air nozzle and is positioned generally parallel to said slope of said inclined face of said air nozzle such that air is directed over said nib via said angled opening.

• said air nozzle having a first wider end configured to direct air through an airway passage at a second narrower end, said second end being truncated to form an inclined face having a slope and an angled opening, and
• said angled opening extending through said inclined face such that said angled opening is in fluid communication with said airway passage of said air nozzle;
• and
• a pen disposed in said pen holder, said pen having a nib,
• wherein said pen is held in close proximity to said angled opening, thereby allowing air to be directed over said nib via said angled opening.

A hand held apparatus for dispensing a fine spray of liquid particles from a pen-like container having a nib, the apparatus comprising:

• a frame including an air nozzle comprising first and second nozzles and a holder for the pen-like container, the air nozzle and the holder each having a longitudinal axis;
• a substantially rigid supporting structure for holding the air nozzle and the pen-like container with their respective longitudinal axes at a fixed angular separation;
• and
• means for providing a flow of air through the air nozzle,
• wherein the first nozzle is configured to direct air into and through the second nozzle,
• wherein the second nozzle has an apertured end which is truncated to form an inclined face having a slope,
• wherein the inclined face comprises an inclined opening against which the nib of the pen-like container is positioned such that the air is directed over the nib of the pen-like container via the inclined opening, and
• wherein a portion of an exposed surface of the nib is held substantially parallel to the slope of the inclined face.
