<p>: A caulker dispenses two viscous components contained separately in inner and outer molded resin chambers. The outer chamber holds one of the components around the inner chamber and is generally cylindrical with standard dimensions to fit existing caulking guns and dispensing equipment. The second component is held within collapsible inner chamber arranged inside outer chamber and having accordion pleats that collapse when axially compressed. Inner chamber has a rear end filling opening, and a molded resin plunger fitting closely within outer chamber is secured to the rear end of inner chamber. The forward regions of both chambers join and form passageways merging at the forward end of caulker. Inner chamber is sealed by an openable barrier, and a removable closure element seals outer chamber. When barrier is opened and closure element is removed and a nozzle with a static mixer is attached, plunger can advance within outer chamber and collapse inner chamber forcing both components and from their chambers and through static mixer before being dispensed out nozzle.</p> |
