A hidden-lock door panel for use in a container includes a door panel body, a covering lid, a first lock, and a second lock. The door panel body includes a hidden space. The covering lid is disposed corresponding to the hidden space and slidably connected to the door panel body. The first lock and the second lock are both disposed in the hidden space. The first lock is an electronic lock and is used to control whether the covering lid can be released to slide. The second lock is used to control the door panel body to be unlocked or locked with respect to the container. Accordingly, unknowing persons are prevented from opening or breaking the door lock.

A code combination lock comprises a lock body whereto a first latch hook and a second latch hook are connected, a first catch 18 fixed in the first opening direction of the case, a second catch 19 fixed in the second opening direction of the case. When locked, the first latch hook engages with the first catch and the second latch hook engages with the second catch. The code combination lock further comprises a push module, a drive module, a lock blade and a code module. The code module is arranged to push the lock blade to fix or unfix the push module such that the push module could push the drive module to lock/unlock. With this kind of code combination lock, one can lock/unlock without having to put in code repeatedly.

The present invention relates to electronic and mechanical dual combination locks. In certain embodiments, electronic and mechanical dual combination locks include: a lock base, a spin dial, a spin dial cover, and a spin dial release conversion mechanism. The lock base includes a mechanical combination lock inside. An electronic combination lock is positioned inside the spin dial cover. The spin dial release conversion mechanism has a spin dial release positioned on the top of the lock base. The spin dial release is used by the user to switch the electronic and mechanical dual combination lock between the electronic combination lock and the mechanical combination lock. When spin dial release is placed in a first position, the electronic and mechanical dual combination lock becomes the electronic combination lock. When the spin dial release is placed in a second position, the electronic and mechanical dual combination lock becomes the mechanical combination lock.

A time capsule includes a housing having a floor and an upper side wall extending upwardly from the floor and a lower side wall extending downwardly from the floor. The floor and the at least one upper side wall together define an upper chamber. The floor and the at least one lower side wall together define a lower chamber. A bottom wall is fixedly attached to lower edges of the at least one lower side wall so as to block access to the lower chamber. A lid is coupled to upper edges of the at least one upper side wall, the lid movable between an open configuration allowing access to the upper chamber and a closed configuration blocking access to the upper chamber, the lid having a lock that holds the lid at the closed configuration until unlocked with a key situated in the lower chamber.
