ABSTRACT:
A removable straw cover that is sterile in combination with a sterile drinking straw protects the drinking straw against bacterial contamination. A line of circumferential indentations separates the straw cover into a upper proximal portion and a remaining distal portion. Separation along such circumferential line of indentations is effected by grasping closed ends of the straw cover and longitudinally extending the straw cover along its longitudinal axis.
