ABSTRACT:
A dual compartment container assembly which comprises a container having two adjacent compartments defined by a common wall and a pair of outer arcuate walls. The container has a filling end which is sealed after contents are placed in the compartments and, of course, has a discharge end at the other axial end of the container. The common wall is pleated to have a "s" shaped curved first width prior to filling and an straightened longer width forming a straight line seal at a point spaced from the filling end. The outer walls and the common wall terminate axially at the filling end to provide a filling end seal region. Pressure forms the seal at the filling end by joining the ends of the outer walls and the seal includes the end of the common wall in the seal. The outer walls are joined with the common wall to form axially aligned pivotal junctions to define bellows by causing the compartments to taper outwardly from a point axially inward from the straight line seal. The bellows form no part of the straight line end seal It is preferred that the straight line seal is a heat seal.
