Patent ID: 7484918

Claim:
A container securement system, the container securement system for securing a container to a support in variable temperature conditions, the container having a lock-actuating opening, the lock-actuating opening having substantially parallel head-engaging portions, the container securement system comprising: a base adapted to be secured to the support, the base comprising a spring-receiving cavity and spring end-fixing means; a shaft supported by the base, the shaft being rotatable about an axis of rotation extendable through the lock-actuating opening, the shaft comprising a head-receiving end and a spring-receiving end, the spring-receiving end extending into the spring-receiving cavity; a head carried by the head-receiving end and adapted to rotate through the lock-actuating opening under forceful contact with the head-engaging portions, the head comprising an upper locking surface and a lower unlocking surface; at least two interchangeable spring elements, a selected one of the interchangeable spring elements being received in the spring-receiving cavity and actuable intermediate the spring-receiving end and the spring end-fixing means by container-provided forces as the head-engaging portions contact the head, the head-engaging portions for applying torque to the shaft via the head, the head being movable through the lock-actuating opening when in an actuated, unlocked, rotational head position and immovable through the lock-actuating opening when in a relaxed, locked rotational head position, the locked rotational head position for preventing head movement through the lock-actuating opening for selectively securing the container to the support.
