Abstract
An instrument for impermanent sealed perforation of thin-walled, hermetically sealed packaging. The instrument includes a longitudinally tapered needle and a septum with a hole. The underside of the septum is coated with a pressure sensitive adhesive. The hole through the septum is configured and arranged to permit unrestricted passage of the distal longitudinal end portion of the needle through the hole, while sealingly engaging the longitudinal midsection of the needle. The septum is incapable of sealing the hole through the septum after withdrawal of the needle from the hole.
