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

A fluid dispensing apparatus comprising:

• a first dispensing bottle configured to dispense a first fluid or semi-fluid and comprising:
• a first hollow, tubular internal chamber;
• a first moveable piston slidably housed within the first internal chamber;
• a first nozzle housing comprising a first inlet, a first airless pump assembly, and a first dispensing nozzle, wherein the first nozzle housing comprises a substantially curved tear drop shape comprising a head portion and a tail portion and
• a first nozzle collar mounted on a top end of the first internal chamber and supporting the first nozzle housing;
• a second dispensing bottle configured to dispense a second fluid or semi-fluid and comprising:
• a second hollow, tubular internal chamber;
• a second moveable piston slidably housed within the second airless internal chamber;
• a second nozzle housing comprising a second inlet, a second pump assembly, and a
• second dispensing nozzle, wherein the second nozzle housing comprises a substantially curved tear drop shape comprising a head portion and a tail portion and
• a second nozzle collar mounted on a top end of the second internal chamber and supporting the second nozzle housing;
• and
• an exterior casing housing the first and second internal chambers, the exterior casing comprising an upper opening and a sleeve disposed thereon, the sleeve having 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;
• and
• wherein the first and second nozzles are separately actuatable so that one of the first and second nozzles can be actuated without actuating the other nozzle;
• and which further comprises a stepped portion in the sleeve having a S-shaped wall and a S-shaped gap defined by inner edges of the first nozzle housing and the second nozzle housing, wherein the gap is supported by the S-shaped wall.
