Abstract
Abstract A dual-chamber dispenser is provided that includes a cap having a dispensing base and a cover, and a pair of elongated hollow tubes attached to an underside of the dispensing base. At an upper dispensing end of each of the tubes is an exit orifice and a coupling mechanism for attachment to the underside of the dispensing base. The upper dispensing end is D-shaped in cross-section. At a lower sealing end of the hollow tube the cross-section is either round or oval. When filled with product, the lower ends of the pair of hollow tubes are crimped together to form a seal.
