There is provided a container/closure lock device that is safe, simple and down-sized with a reduced number of components and can be manufactured at reduced cost. A container is provided with brackets 14a through 14f for receiving the wall of a closure, each of said brackets 14a through 14f being provided with a through bore 17 bored through its arm 16. Pin holders 19a through 19f having respective channels 22 are fitted to the respective outer surfaces of the corresponding brackets 14a through 14f, the through bores 17 and the corresponding channels 22 being aligned respectively. Lock pins 26a through 26f are respectively inserted into and held to the corresponding channels 22. A rotary ring 29 provided with slots 30a through 30f is fitted to the outer peripheral surface of the container 11 in such a way that the slots 30a through 30f respectively intersect the corresponding lock pins 26a through 26f. Guide pins 31a through 31f are respectively made to pass through the corresponding slots 30a through 30f and the corresponding lock pins 26a through 26f. The wall 34 of the cap-type closure 33 is provided with lock holes 35a through 35f for receiving corresponding lock pins.
A container/closure lock device for locking a cap-type closure fitted to an opening of a container characterized in that the container is provided on an outer surface of a peripheral wall and close to the opening thereof with a bracket having an arm for receiving a wall of the closure in a gap between the arm and the outer surface of the peripheral wall of the container and a through bore formed through the arm of the bracket in order to removably receive a lock pin, that a pin holder having a channel for holding the lock pin is secured to an outer surface of the arm of the bracket, said through bore for removably receiving the lock pin being aligned with the channel for holding a lock pin, that the lock pin is passed through the channel and the corresponding through bore to move into and out of the gap between an inner surface of the arm of the bracket and the outer surface of the peripheral wall of the container, that a rotary ring having a slot for guiding a guide pin is provided and fitted to an outer periphery of the opening of the container with the slot located in alignment with the lock pin, said slot being arranged obliquely so as to intersect a radial line and a circle coaxial with the ring, that the guide pin is made to pass through the slot in the ring and the corresponding lock pin in order to securely link the ring and the lock pin and that the closure is provided on the wall thereof with a lock hole for receiving the lock pin.
A closure cap lock for locking a closure cap having a peripheral wall telescoped onto a peripheral wall defining an opening to be closed by the closure cap, said lock comprising a plurality of circumferentially spaced, radially movable locking pins, a plurality of circumferentially spaced brackets rigidly mounted on the peripheral wall defining the opening and outwardly of the peripheral wall of the closure cap, each of said brackets guidingly supporting a locking pin for radial inward and outward movement, said locking pins lockingly engaging the peripheral wall of the closure cap when moved to an inward position and releasing the peripheral wall of the closure cap when moved outwardly, and a locking pin actuating member simultaneously actuating all of said locking pins to move them between said inward cap locking position and said outward cap releasing position.
