Abstract
A tamper resistant filling and containment system useful in medicinal and related applications. A bladder includes at least two ports with one of the ports having a graspable, reciprocable tube inserted therein. The tube has an axially bore formed partially therethrough which terminates at side passages which communicate with the bladder when the tube is in a filling position. Movement of the tube to a second position prevents communication of the side passages with the bladder and a weakened portion of the tube located at the side passages permits the graspable or outer portion of the tube to be broken, thereby preventing access to the tube and movement thereof to the filling position.
