ABSTRACT:
A tamper-evident closure seal for containers such as syringes or syringes with an attached needle. The seal includes a plurality of slits therein which inhibit removal of the seal from the container once the seal has been placed on the container. The method includes deformation of a portion of the slitted area of the seal in order to strengthen the seal in the area of the slits so as to improve removeability of the seal from its release liner prior to attachment thereof to the container, without inadvertent or premature destruction of the seal.
