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.
Claims10
A method for impermanent sealed perforation of a thin-walled, hermetically sealed packaging, comprising:
- (a) obtaining a septum having a hole,
- (b) obtaining a longitudinally-tapered, blunt-tipped, needle having a longitudinal lumen, a proximal longitudinal end portion, a distal longitudinal end portion and a longitudinal midsection,
- (c) adhering the septum to a wall of the packaging,
- (d) inserting the distal longitudinal end portion of the needle through the hole in the septum until the needle perforates the wall of the packaging so as to form an opening through the wall, and the longitudinal midsection of the tapered needle is sealingly wedged within the hole,
- (e) removing content from the packaging through the lumen,
- (f) withdrawing the needle from the hole in the septum so as to leave an unsealed hole through the septum and an unsealed opening through the wall of the packaging.
