A fuel cap for a vehicle has a locking structure configured to generate a sound interval, including a head portion having a handle formed at a first side and one or more striking portions installed at a second side, and a body portion integrally assembled with the head portion and having a plurality of sound generators installed at the body portion and disposed in a state of being struck by the one or more striking portions installed at the second side of the head portion according to a rotation of the head portion by a locking torque.

A fuel cap in accordance with the present disclosure includes a closure body and a valve unit integrated with the valve body. The closure body is adapted to engage a fill neck coupled to a fuel tank. The valve unit is configured to selectively vent excess pressure and/or vacuum developed in the fuel tank through the closure body to manage pressure in the fuel tank.

The invention relates to a tank cover for mounting on a filler neck of a container, including a grip cap, a threaded part and a locking mechanism which is provided between the grip cap and threaded part, wherein the locking mechanism is formed by latching noses and by elastically deformable latching lugs interacting therewith, the latching lugs are integrally formed on the threaded part and the latching noses are integrally formed on the grip cap, or the latching lugs are integrally formed on the grip cap and the latching noses are integrally formed on the threaded part. Here, the latching lugs are formed on or in the vicinity of a thread turn of the threaded part.

The present disclosure provides a torque element to transmit torque between a first part and a second part of a cap assembly. The torque element includes a base having a first surface and a second surface opposite to the first surface; and an annular wall extending from the base in a direction away from the second surface. The first surface of the base includes at least one first ratchet and the annular wall includes at least one second ratchet on an outer side.
