A flexible check valve is introduced within a fluid path for leakage protection. The flexible check valve is preferably a crossbill used in conjunction with a drinking straw to prevent undesired liquid leakage from a container such as a drink box. A transition section is used to mate the dissimilar materials of the straw and flexible check valve. The transition section retains an internal bayonet section of the flexible check valve within a snap-fit ring.
