Abstract
A molded collapsible solution container which defines a body portion having an integral neck portion and a relatively stiff shoulder portion and sealed at the opposite end, with gusset portions defined in the body portion adjacent the shoulder portion at opposite sides thereof. The shoulder portion extends outwardly from the neck portion and also extends axially rearwardly away from the neck portion in tapered manner. Sections of the shoulder portion adjacent the gusset portions normally extend in a plane perpendicular to the longitudinal axis of the container, being connected to the remainder of the shoulder portion by an angular crease line and being flexible to permit axially forward bending of the sections about the crease line as the container collapses by draining. Also, the tail seal at the opposite end may define a convex, arcuate seal for improved strength.
