A method of delivering a glutinous substance from a cartridge to an applicator is disclosed. The method comprises receiving the cartridge inside a sleeve through an inlet of the sleeve while a pressure cap is in an open position. The method also comprises moving the pressure cap into a closed position to sealingly couple the pressure cap with a trailing end of the cartridge and to sealingly couple the applicator with a leading end of the cartridge. The method further comprises applying pressure to the glutinous substance in the cartridge through the pressure input of the pressure cap to urge the glutinous substance from the cartridge into the applicator. Additionally, the method comprises moving the pressure cap into the open position to provide sufficient clearance sufficient for removal of the cartridge from the sleeve through the inlet of the sleeve.
