<p>Quantities of two low viscosity liquid components are provided in separated portions of a flexible bag or package (12). Separable attachment (18) of package walls between the liquid components is broken, and the liquids are mixed together within the package (12) by manipulating its flexible walls (15). The flexible package (12) containing the mixed components is inserted into a barrel (22) of a dispenser, and a portion (32) of the package (12) adjacent the front end of the barrel (22) is removed. A nozzle (28) is attached to the front end of the barrel (22) and a driving mechanism is manually activating to drive a plunger (26) along the barrel (22) toward the nozzle (28) to compress the flexible package (12) and thereby dispense the material in the package (12) through the nozzle (28). When mixed the liquid components first form a higher viscosity, non-sag, non-flowing, thixotropic composition for a period of time during which dispensing from the dispenser can occur, and thereafter form a resiliently flexible solid sealing composition.</p> |
