Abstract

The closure (1) consists of a tubular base portion (2) and a cap (3). Considered in the direction of the axis (17) of the base portion (2), in the closed position the outer contour of the cap (3) is within the interior contour of the base portion (2). Cap and base portion are connected to each other in a single unit by a snap hinge and injection molded in a closed position. Extending from the snap hinge, cap and base portion are additionally connected together by a safety strap (40), which is to safeguard against unintentional premature opening of the closure (tamper evidence). The closure enables a marked productivity increase during manufacture.
