ABSTRACT OF THE DISCLOSURE A blow molded collapsible solution container having improved characteristics of collapsibility as shown. The container defines a body portion having an integral neck portion and a generally elongated, re- latively stiff shoulder portion at one end thereof, and is sealed at its opposite end. The body portion defines, in its original, unstressed configuration, a generally oval transverse cross section adjacent the shoulder portion, said cross section tapering progres- sively to a flat configuration at said end of the container opposite to said one end to facilitate a uniform, flat collapse of the container progressively from said opposite end towards said one end as the contents thereof are withdrawn through said neck portion when the container is disposed in neck-downward position. The container also defines gusset portions in the body portion adjacent the shoulder portion. The gusset portions include lines of flexing weakness to facilitate collapse of the container adjacent the shoulder portion as the contents thereof are withdrawn. The gusset portions de- fine three sides in triangular relationship, one of said sides being adjacent and parallel to a shoulder tip at the ends of the major axis of said elongated shoulder portion, and the other two sides extending from said one side of the gusset portion toward each other. The container is free of longitudinally oriented lines of flexing weakness adjacent the shoulder portion.
