ABSTRACT:
A closure is provided for a container such as a flexible bag for I.V. liquids which is easily removed therefrom with a minimum amount of force. The easily-removable cap structure affords a sterile closure system, yet at the same time is susceptible of different geometric configurations which concentrate pulling forces in a confined area and in conjunction with a pre-weakened tear line so that a force not exceeding more than about 12 pounds will initiate a tearing away of the cap structure so as to expose the port and the contents of the container.
