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.
Plastic closure comprising a base (1) connectable with a container opening and a cap (2) connected thereto in one piece by means of a hinge (3), a tamper-proof strip (4), which can be torn off, is provided on the base and is positioned diametrically to the hinge (3), characterized in that at the most the tamper-proof strip (4) extends over half the circumference of the cap (2) and in this area at least approximately extends over the full height of the cap and on the side facing the hinge is provided a pressing depression (7) which, in the closed state of the closure, is completely concealed by the tamper-proof strip (4).
