Abstract: A drinking vessel including a beverage container and a closure assembly attachable to the beverage container. The beverage container has a spout defining a first drinking opening and a second drinking opening. The closure assembly includes a positioning member and a sealing member. When the positioning member is in a sealing orientation, the positioning member can extend deep enough into the first drinking opening for the sealing member to seal the first drinking opening and the second drinking opening. When the positioning member is not in the sealing orientation, the positioning member cannot extend deep enough into the first drinking opening for the sealing member to seal the first drinking opening and the second drinking opening.

Abstract: A security bar providing improved security from breach is obtained with the use of a fiber optic cable longitudinally inserted in a hollowed out cavity thereof. Monitoring of the security bar to identify attempts at breach thereof may be achieved by connecting an optical light source to one end of the fiber optic cable and a light monitoring device (i.e., an optical receiver) at the other end. In this manner, a breach of the security bar is identified when the optical receiver fails to receive the light generated by the optical light source. In one embodiment, an isolator which consists of a material that is soft enough to absorb a potential shock but hard enough to break or splinter if the security bar is substantially deformed (e.g., wood) surrounds the fiber optic cable.

Abstract: A security bar providing improved security from breach is obtained with the use of a plurality of free rolling inner bars. Illustratively, three inner rolling bars, arranged in a triangular relationship, are provided inside a cylindrically hollowed out outer bar, thereby ensuring that no inner bar can be attacked simultaneously from opposing sides thereof. The inner bars may be surrounded with a ring of ball bearings to provide for their ability to roll freely in place with respect to the outer bar. Electronic monitoring of the security bar identifies attempts to breach the security bar.
