The present application provides a cap assembly and a bottle assembly. The cap assembly is configured to lock a bottle. The bottle includes a bottle head having at least one lock accommodating portion and comprises a bottle body. The cap assembly includes a cap, an elastic arm and at least one lock portion. The cap defines an annular receiving portion having an opening facing downward, and the bottle head can enter the receiving portion through the opening. The elastic arm is annular and is arranged in the receiving portion. The at least one lock portion is arranged on the cap and is configured to be capable of cooperating with the at least one lock accommodating portion of the bottle head, so as to lock the cap assembly to the bottle head. When the cap assembly is locked to the bottle head, the elastic arm abuts against a top wall of the receiving portion and a top wall of the bottle head, to apply forces in opposite directions to the cap and the bottle head, so as to retain the at least one lock portion in the at least one lock accommodating portion. The cap assembly of the present application has a relatively small height, and during unlocking of the bottle assembly of the present application, gas in a bottle body cavity can be discharged from the bottle through an exhaust passage.

Locking a lid while controlling cost increases. In a lid opening and closing device, an engagement receiver and a lock member is provided on a base and a lid respectively. A base-end portion of a drive-link is rotatably coupled to the base, and a tip-end portion of the drive-link is coupled to the drive-link coupling of the lid. By rotating the drive-link to one side in a rotation direction by an actuator, the lid moves from an open to a closed position to close the opening. The drive-link coupling couples the drive-link to the lid so that a relative rotation of the drive-link to the lid in the closed position is allowed. When the drive-link rotates relative to the lid to said one side in the rotation direction, the lock member is switched to a locked state. This allows the lock member to be in the locked state utilizing the actuator.

A vacuum sealable container for securing and transporting extraterrestrial samples and a method of securing an extraterrestrial sample is provided. The vacuum sealable container includes a container body and a lid assembly. The lid assembly is connectable to the container body configured to selectively form a hermetic two-way seal between the container body and the lid assembly. A locking mechanism is situated on an end of the lid assembly opposite the container body, the locking mechanism configured to secure the lid assembly to the container body, forming the seal.
