ABSTRACT:
A molded, collapsible container for intravenous solutions characterized by a controlled collapse along major sidewall portions. The container comprises the shoulder portion having a rigid neck; a hanger portion at an end of the container opposite from the neck; a pair of opposed minor sidewall portions, defined by relatively sharply angled edges; and major sidewall portions extending between the minor sidewall portions which collapse upon each other, while the minor sidewall portions remain in relatively fixed relationship and hold the container apart near the edges of the container. The container may also be provided with intermediate sidewall portions angled relative to the major and minor sidewall portions, which serve to provide a larger fluid capacity to the container. A waist portion is also provided which is relatively smaller circumferentially, compared to the rest of the container. The waist portion provides a rigidifying area which allows air to flow across the width of the container and down along its sides adjacent the minor sidewall portions.
