ABSTRACT:
A collapsible container for medical fluids which is blow molded in such a manner that when the container is supported at one end, the side wall portions will automatically become self-pleating and will continue to assume a pleating condition toward the bottom of the container as the medical fluid is emptied therefrom. This self-pleating aspect is accomplished by blow molding the container in such a manner that the shoulder and side wall portions are of an average smaller dimension throughout the longitudinal axis of the body section and the shoulder portions join the side wall portions at an angle so as to effect a structurally weak point when the bag is supported by a hanger tab. This self-pleating phenomenon results in a container wherein the meniscus of the fluid is readily readable and accurately ascertained.
