Abstract
A reversible and reusable caulk dispenser for use with a caulk gun. The caulk dispenser has a tubular cartridge with a plunger inside the cartridge near a first open end of the cartridge and an end cap with a nozzle that can be attached at an open second end of the cartridge. A foil packet of caulk or sealant material is inserted in the cartridge of the dispenser. A closed end of the packet is positioned adjacent the plunger while an open end of the packet is at the end of the cartridge where the end cap is attached. The dispenser is used in a standard caulk gun and the caulk material expelled through the nozzle as the caulk gun is operated. When the packet is emptied the dispenser can be reused with a new packet inserted and the end cap attached now to the opposite end of the cartridge.
Claims17
A reusable and reversible caulk dispenser comprising:
- a tubular cartridge defining an internal chamber, the cartridge comprising an open first end and an open second end;
- a cylindrical plunger disposed within the internal chamber and concentric with the cartridge, the plunger comprising:
- a circumferential outer wall having a first end and a second end;
- a circular center plate disposed within the cylindrical outer wall, the center plate having a first planar side and a second planar side;
- a first inner wall, the first inner wall tapering from the first end of the outer wall to the first planar side of the center plate;
- and
- a second inner wall, the second inner wall tapering from the second end of the outer wall to the second planar side of the center plate;
- and
- an end cap comprising:
- a circular planar cap face having a top side and a bottom side, the cap face defining a discharge port at a center of the cap face;
- an outer ring extending from the bottom side of the cap face, the outer ring being cylindrical and concentric with the cap face;
- an inner ring extending from the bottom side of the cap face, the inner ring being cylindrical and concentric with the cap face;
- and
- a nozzle extending from the top side of the cap face, the nozzle being cylindrical in nature and defining a flow path through the discharge port of the cap face;
- wherein the outer ring is disposed proximate a perimeter of the cap face and the inner ring is disposed proximate a perimeter of the discharge port of the cap face;
- wherein the end cap is adapted to be removably attached to the first end or the second end of the cartridge.
A reusable and reversible caulk dispenser comprising:
- a tubular cartridge defining an internal chamber, the cartridge comprising an open first end and an open second end;
- a cylindrical plunger disposed within the internal chamber and concentric with the cartridge;
- and
- an end cap comprising:
- a circular planar cap face having a top side and a bottom side, the cap face defining a discharge port at a center of the cap face;
- an outer ring extending from the bottom side of the cap face, the outer ring being cylindrical and concentric with the cap face;
- an inner ring extending from the bottom side of the cap face, the inner ring being cylindrical and concentric with the cap face;
- and
- a nozzle extending from the top side of the cap face, the nozzle being cylindrical in nature and defining a flow path through the port of the cap face;
- wherein the outer ring is disposed proximate a perimeter of the cap face and the inner ring is disposed proximate a perimeter of the discharge port of the cap face;
- and
- wherein the end cap is adapted to be removably attached to the first end or the second end of the cartridge.
A method for using a caulk dispensing system, the method comprising:
- inserting a packet of material in a tubular cartridge of a reusable caulk dispenser,
- the cartridge having an open first end and an open second end;
- such that a closed end of the packet is adjacent a plunger disposed in the cartridge;
- and
- such that an open end of the packet is proximate the first end of the cartridge;
- attaching an end cap comprising a nozzle to the first end of the cartridge;
- placing the caulk dispenser in a caulk gun;
- operating the caulk gun to advance the plunger in the cartridge and thereby expel material from the packet in the caulk dispenser through the nozzle of the end cap;
- such that the packet is compressed around an inner ring of the end cap;
- removing the caulk dispenser from the caulk gun;
- removing the end cap from the first end of the caulk dispenser;
- removing the packet of material from around the inner ring of the end cap of the caulk dispenser;
- inserting a new packet of material in the second end of the cartridge of the caulk dispenser;
- such that a closed end of the new packet is adjacent the plunger;
- and
- such that an open end of the new packet is proximate the second end of the cartridge;
- attaching the end cap to the second end of the cartridge;
- and
- placing the caulk dispenser in the caulk gun.
