A collapsible travel tumbler is described. The tumbler includes a collapsible container made of flexible material. The collapsible container is inserted through a rigid collar, on the top edge of which the collapsible cup sits. A lid with a sealable drinking hole is then screwed onto the collar, providing a complete and secure closure of the collapsible tumbler. When not in use the collapsible container can be collapsed into the housing created by the combination of the collar and the lid for easy storage and transport.

Collapsible travel tumbler

A closure system for a drinking bottle or other container is disclosed. The closure system comprises a bottle and a bottle closure. The bottle closure, in turn, comprises among its components a cap interface manipulated directly by the user's hand, a platform that translates vertically in relation to the cap interface, and a flexible annular stopper body directly manipulated by the platform. When the bottle closure is placed on the open bottle neck and the cap interface is pushed downward toward the bottom of the bottle, a lever-based mechanism forces opposite upward movement of the platform. The platform squeezes the stopper body, and at the end of the downward pushing motion, the system is locked in a static position. The squeezed stopper body forms a liquid-tight seal with the bottle, while holding potential energy via elastic deformation. From this sealed position, the cap interface may be radially twisted relative to the bottle, releasing the locked platform and the stopper's potential energy. As the stopper gains its original shape, simultaneously the liquid-tight seal is removed, the cap interface moves upward, and the platform moves downward. The loosened bottle closure may now be separated from the bottle.
