ABSTRACT:
A one piece plastic closure comprises a base which is attachable to a container and a cap attached to the base of the closure by a hinge. A safety band is molded together with the base, to which it may be attached by webs. The safety band overlays approximately half the perimeter of the cap and its height is generally the same as that of the cap itself. In this way, the cap cannot be grasped in the area opposite the hinge, and thus cannot be opened. A lug may additionally be provided on the cap which is engageable in a corresponding recess in the safety band to provide the closure in a closed and sealed condition, thus holding the closure and preventing it from opening under the effect of excess pressure in the container.
