Abstract
A curable liquid dispensing pen has a pen body to which a curable liquid dispensing reservoir may be removably attached. The pen body further has a coupling which may be coupled to a source of pressurized air. The air is directed through a passage in the pen body to the reservoir. The pressurized air moves a piston in the reservoir to cause curable liquid to be dispensed from the reservoir. A controller provides a timed pulse of pressurized air to the curable liquid dispensing pen and this controls the volume of curable liquid dispensed from the reservoir.
Claims15
A curable liquid dispensing pen comprising:
- a pen body having a first end, a second end, and a passage extending from said first end to said second end, said second end adapted to be coupled to a source of pressurized air;
- a dispensing reservoir removably coupled to said first end of said pen body, said dispensing reservoir containing a curable liquid and having an opening for receiving the pressurized air from said passage and an outlet for dispensing the curable liquid;
- and
- a piston positioned in said reservoir and adapted to be moved toward said outlet by pressurized air directed from said passage through said opening to dispense the adhesive.
A system for dispensing curable liquid, the system comprising:
- a pen body having a first end, a second end, and a passage extending from said first end to said second end, said second end adapted to be coupled to a source of pressurized air;
- a dispensing reservoir removably coupled to said first end of said pen body, said dispensing reservoir containing a curable liquid and having an opening for receiving the pressurized air from said passage and an outlet for dispensing the curable liquid;
- a piston positioned in said reservoir and adapted to be moved toward said outlet by pressurized air directed from said passage through said opening to dispense the adhesive;
- and
- a controller adapted to be coupled to the source of pressurized air and operative to send a timed pulse of the pressurized air to said passage to control the volume of curable liquid dispensed from said reservoir.
A pen body for use in dispensing curable liquid from a dispensing reservoir, the pen body comprising:
- an elongate pen barrel having a first end and a second end;
- a finger grip positioned on said pen barrel between said first and second ends and configured to be gripped by a user during a dispensing operation;
- a passage through said pen barrel extending from said first end to said second end;
- a connecting element coupled to said pen barrel and configured to removably retain the dispensing reservoir proximate said first end of said pen barrel such that said dispensing reservoir is in fluid communication with said passage;
- and
- a coupling on said pen barrel adapted to receive a conduit for supplying pressurized air to said passage.
A dispensing reservoir for use with a curable liquid dispensing pen, the dispensing reservoir comprising:
- a reservoir body having an interior containing a curable liquid, a first end, a second end having an opening, and a flange surrounding said opening, said flange configured to couple with the dispensing pen in a releasable manner;
- an elongate tube having an inlet and an outlet, said tube coupled to said reservoir body with said inlet in fluid communication with said reservoir body interior and said outlet adapted to dispense said curable liquid;
- and
- a piston positioned for movement within said interior, said curable material being on one side of said piston and said opening being on an opposite side of said piston, said piston adapted to be moved by the pressurized air introduced on said opposite side to urge said curable liquid from said outlet.
