Abstract
A cartridge suitable for containing a sealant material and a matching caulking gun. The cartridge comprises an elongate hollow body defined by a peripheral wall. A coupling flange extends outwardly from at least a portion of the peripheral wall and has an abutment surface configured to enable engagement with a corresponding abutment surface of a caulking gun, to thereby connect the cartridge to the caulking gun. The abutment surface of the coupling flange faces upwardly towards the top end of the cartridge body and is disposed at an obtuse angle with respect to the peripheral wall so as to enable a downward force to be applied to the flange by a corresponding downwardly facing abutment surface of a caulking gun.
