TRAVEL TUBE
A reusable travel tube that has a flexible tube portion, a collar and a cap that can be threaded onto the cap. The collar is fitted over a neck of the tube portion and forms a gasket-like seal between the neck of the tube portion and the collar. The cap has a rotatable locking bail that can prevent a flip-top cap from accidentally being opened. When the locking bail is not positioned to prevent the cap from being accidentally opened, it can be retracted into a nested position such that the handle of the bail is substantially flush with the outer side surface of the collar.
