The disclosed invention relates to maintaining a closed and secured position of a tank fill port cap on a tank such as a fuel tank. The invention comprises a dual collar structure providing a means for the attachment of a lockable blocking device to prevent a tank fill port cap from being removed from a tank fill port nipple. The lockable blocking device is removably and securely installed on a first collar and wherein the first collar is removably and securely installed on a tank fill port nipple such as on a large commercial truck fuel tank. The first collar and the blocking device discourages or prevents the theft or vandalism of the contents of the tank. The first collar attaches to the tank fill port nipple with setscrews in a continuous one piece collar or a clamp screw in a clamping split collar configuration. A second collar is fitted over the first collar covering the first collar attachment means preventing tampering or removal of the first collar. The second collar is secured in position by the blocking device being attached to the first collar requiring the blocking device to be removed from the first collar in order to remove the second collar from the first collar, therefore, maintaining a secure and removable dual collar device locking device to secure and protect the contents of a tank by preventing the tank cap from being removed. In addition, the lockable blocking device is required to reside in a position that does not interfere with a tank pressure relief device that may be centered in the fill port cap.

A fully automatic inductive sample-collecting bucket capable of storing sample information includes a bucket, and a bucket cover snap-fitted to an upper end of the bucket. A bucket cover cavity is formed in the bucket cover. A locking mechanism, and a control mechanism for driving the locking mechanism to act are integrated in the bucket cover cavity. An integrated circuit (IC) card inductive control assembly is integrated in the bucket cover. The bucket is provided with a radio frequency identification (RFID) chip. The IC card inductive control assembly is configured to identify IC card unlocking information of an external grip for cover opening work and to drive the control mechanism to work to control an action of the locking mechanism. The sample-collecting bucket integrates an RFID card capable of carrying sample coding information, and can realize the automatic cover-sealing and cover-opening function under the identification and control of the controller.

A drinking device that includes a receptacle for holding a liquid, a cover removably attached to the receptacle to encapsulate the liquid within the receptacle, and a locking element. The cover has a drinking opening that allows a user to access the liquid within the receptacle. The locking element is attached to one of the cover or receptacle, and configured to engage the other of the cover or receptacle. The locking element is movable between one or more locking positions for securing the cover to the receptacle, where a first locking position of the locking element secures the cover to the receptacle and prevents a user from accessing liquid through the drinking opening.
