Dual chamber medicament dispenser

A dual compartment container assembly, comprising:

• a container having two adjacent compartments defined by a common wall segment and a pair of outer arcuate walls, said container having a filling end which is sealed after contents are placed in said compartments;
• said common wall segment being curved to have a first width prior to filling and a second straightened longer width after said filling end is sealed to form a straight line seal at said filling end;
• said outer arcuate walls and said common wall segment terminating axially at said filling end to provide a filling end seal region such that pressure forming a seal at said filling end joins the terminal ends of said outer arcuate walls to form a straight line seal and said filling end seal region includes the terminal end of said common wall segment in said filling end seal region;
• and
• said outer arcuate walls extend arcuately from junctions with said common wall segment to form bellows between said compartments, said arcuate walls being joined at each junction with said common wall segment to form axially aligned pivotal junctions to define said bellows by causing said compartments to taper outwardly from a point axially inward from said straight line seal, said bellows terminating at a point axially spaced from said seal region such that none of the bellows in included in the straight line seal.
