Abstract
Apparatus for dispensing a fine spray of liquid particles 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 the nib of a pen releasably supported within a holder with the pen nib in close proximity with the nozzle outlet to cause liquid from the pen to be dispensed as a fine particulate spray in air.
Claims11
Apparatus for dispensing a fine spray of liquid particles, the apparatus comprising:
- a nozzle having a nozzle outlet;
- a manually operated pump connected to supply air under pressure directly to the nozzle;
- and
- a pen-like container having a nib and a shoulder adjacent the nib and being supported within a holder so that the nib is in close proximity to the nozzle outlet and so positioned that air leaving the nozzle outlet is directed onto and over the nib to cause liquid from the pen-like container to be dispensed as a fine particulate spray in air, the nozzle outlet being formed with a step to define an abutment surface against which cuts the shoulder of the pen-like container to correctly locate the nib with respect to the nozzle outlet.
Apparatus for dispensing a fine spray of liquid particles, the apparatus comprising:
- a nozzle having an outlet;
- a flexible hose connected to the nozzle;
- a foot operated pump connected to supply air under pressure through the flexible hose directly to the nozzle, the nozzle outlet being formed with an abutment surface;
- and
- a pen-like container having a nib and having a surface adjacent the nib, the surface being located against the abutment surface of the nozzle outlet so the nib is in close proximity to the outlet of the nozzle whereby air under pressure from the pump is directed onto and over the nib to entrain particles therefrom and dispense such particles as a fine spray.
Apparatus for dispensing a fine spray of liquid particles, the apparatus comprising:
- a nozzle having a nozzle outlet;
- a holder connected to the nozzle and having a channel;
- a manually operated pump connected to supply air under pressure directly to the nozzle;
- and
- a pen-like container having a nib and a shoulder adjacent the nib and being supported by a sleeve detachably mounted within the channel of the holder, the nozzle outlet being formed with a step to define an abutment surface against which abuts the shoulder of the pen-like container to correctly locate the nib with respect to the nozzle outlet so that air leaving the nozzle outlet is directed onto and over the nib of the pen-like container, the nib being in close proximity to the nozzle outlet to cause liquid from the pen-like container to be dispensed as a fine particulate spray in air, a plurality of sleeves being provided each of differing internal cross-section to enable a variety of pen-like containers of different cross-section to be retained within the holder.
Apparatus for dispensing a fine spray of liquid particles, the apparatus comprising:
- a nozzle having a nozzle outlet;
- a manually operated pump connected to supply air under pressure directly to the nozzle;
- a pen-like container having a nib and being supported within a holder so that the nib is in close proximity to the nozzle outlet and so positioned that air leaving the nozzle is directed onto and over the nib to cause liquid from the pen-like container to be dispensed as a fine particulate spray in air;
- and
- wherein the pump comprises a piston slidably mounted within a cylindrical chamber, movement of the piston forcing air under pressure through the nozzle, and wherein the piston is hollow to house the pen-like container when the pen-like container is not in use.
