Dual-chambered bottles for storing and dispensing of fluid and semi-fluid materials

Abstract

In one embodiment a fluid dispensing apparatus includes a first dispensing bottle configured to dispense a first liquid, a second dispensing bottle configured to dispense a second liquid, an exterior casing. The first dispensing bottle may include a first hollow, tubular internal chamber, a first moveable piston slidably housed within the first internal chamber, a first nozzle housing, and a first nozzle collar mounted on a top end of the first internal chamber and supporting the first nozzle housing. The first nozzle housing may include a first inlet, a first pump assembly, and a first dispensing nozzle. The second dispensing bottle may include a second hollow, tubular internal chamber, a second moveable piston slidably housed within the second internal chamber, a second nozzle housing, and a second nozzle collar mounted on a top end of the second internal chamber and supporting the second nozzle housing. The second nozzle housing may include a second inlet, a second pump assembly, and a second dispensing nozzle. The exterior casing may house the first and second internal chambers. The exterior casing may include an upper opening and a sleeve disposed thereon. The sleeve may have inner contours complementary to the first and second nozzle housings such that the first and second nozzle housings at least partially protrude through the sleeve.
