There is provided a pipe thread protector according to a first aspect. The pipe thread protector includes a tubular body shaped to protect a threaded end portion of a pipe or a pipe coupling. The tubular body includes an inner portion with a first of right-handed and left-handed threading. The tubular body includes an outer portion with a second of right-handed and left-handed threading. The pipe thread protector includes an end member. The end member includes the second of right-handed and left-handed threading via which the end member threadably couples to the outer portion of the tubular body. The pipe thread protector includes a locking member with a first position in which removal of the end member from the tubular body is inhibited. The locking member is moveable from the first position thereof to a second position in which the end member is selectively removable from the tubular body.

A container for the transport and storage of liquids comprises at least one upwardly open socket at the top of an inner container. A clamping disk has an internal thread that can be screwed onto an external thread of the socket, thereby clamping a container top at the edge of its opening. A screw lock interacts with the external thread of the socket and the internal thread of the clamping disk and prevents unintentional loosening of the clamping disk and the socket.
