A straw permitting a lid to be set with the straw kept in a container even when drinking water still remains in the container after a first drink, the suction tip of the straw to pop out of the container when the lid is removed and the straw to be reused, wherein a straw body is of an elastic construction in which at least part thereof is helical spring-like or bellows-like or the tip end thereof is cut into slices in the lengthwise direction. When the drink in the container cannot be taken at a gulp, the cap is set to push down the suction tip of the straw into the remaining drink; when the drink in the container is to be taken again, the lid is opened to allow the suction tip to rise by the elastic mechanism and pop out of the mouth of the PET bottle enabling the straw to be reused directly.
