Abstract
Abstract A plastic cup for containing barium sulfate suspension and having a leak-proof removable lid. The lid has an opening through which a soft vinyl straw passes. The diameter of the straw is large enough to permit the patient to rapidly take in the desired mouthful of suspension. The lid opening is slightly undersize relative to the straw so that a leak-proof relationship is created. However, the size of the opening is such that this vinyl straw can readily be moved into any position relative to the lid and thus the bottom of the straw can be positioned anywhere within the cup.
