  • Publication number: 20120017412
    Abstract: A package (10) for the storage and dispensing of a plurality of material 10as includes a first and a second longitudinally juxtaposed barrels (11, 12). Each barrel (11, 12) having a first and a second end (20, 21). Each first and second barrels (11, 12) having a quantity of at least one of the material 10as initially contained therein, and each barrel having an open end (20) and a dispensing end (21). A piston (40) is disposed in each barrel (11, 12) such that the material 10a in each barrel (11, 12) is initially positioned between the dispensing end (21) of the barrels (11, 12) and the respective ones of the pistons (40). A snap cap (23) is contiguously formed to initially close each of the dispensing ends (21) of the barrels (11, 12), such that the snap cap (23) may be broken from the barrels (11, 12) to thereby forming a secondary open end (31) at the dispensing end (21) of the barrels (11, 12), thereby facilitating the material 10a contained in each barrel (11, 12) to flow through and be dispensed.
