A cap may include a threaded inner body and an outer cover. A ratchet mechanism may be operatively positioned between the inner body and the outer cover to directly transmit rotation from the outer cover to the inner body in the cap-unthreading direction and to transmit no more than a predetermined amount of torque from the outer cover to the inner body in the cap-threading direction. A gauge assembly may include a float, an indicator dial, and a pointer. The float is supportable at a level of fluid within the container, and the pointer is movable in response to movement of the float with the level of fluid in the container. The pointer cooperates with the indicator dial to indicate the level of fluid in the container. A translucent crystal may be positioned over the indicator dial and the pointer. The crystal may be fixed relative to the inner body.
