Closure of vessel

Abstract

Disclosed is a closure of a vessel that is prevented from being arbitrarily opened. The closure of a vessel comprises: an inner closure mounted to a vessel inlet of a vessel; an outer closure disposed on an outer circumferential surface of the inner closure so as to perform an idle rotation with respect to the inner closure; a rotation force transmitting portion formed between the inner closure and the outer closure for transmitting a rotation force of the outer closure in an opening direction to the inner closure only when the outer closure is downwardly pressed by force more than a predetermined force; and a protection plate supported by a spacer that maintains a gap between the inner closure and the outer closure by being disposed therebetween, and detachably installed to the outer closure with constituting a part of an upper surface of the outer closure, for allowing the outer closure to perform only an idle rotation with respect to the inner closure in an opening direction, and for transmitting a rotation force of the outer closure to the inner closure when the protection plate is detached from the outer closure and the outer closure is downwardly moved by a force more than a predetermined force from the rotation force transmitting portion.
