ABSTRACT:
A molded collapsible solution container defines a chamber-defining body portion wall having an integral neck portion and a shoulder portion at one end thereof. The container defines a pair of opposed gusset portions adjacent the shoulder portion at opposite ends of the shoulder portion, with the shoulder portion defining opposed shoulder edges extending between the gusset portions. A pair of opposed lines of flexing weakness are defined in the collapsible solution container and exhibit an arcuate cross section which extends inwardly of the container. The opposed lines of flexing weakness are positioned on each side of the container in generally parallel relation to the opposed shoulder edges with the opposed lines of flexing weakness being longitudinally spaced from the shoulder edges by a distance which is proportioned to cause the opposed lines of flexing weakness to abut one another as the container collapses inwardly about the opposed shoulder edges. Accordingly, the abutting lines of flexing weakness inhibit further collapse of the container under the pressure of suction, to slow the rate of subsequent collapse.
