Contoured tubing closure

摘要

The present invention provides a system and method for delivering fluid. In one embodiment, the system and method include a container to hold the fluid, and a closed-end tube having a first end in communication with the container and a closed second end. The closed second end is contoured in a pattern to form a zone of weakness. The zone of weakness facilitates reduced force necessary for an access spike to puncture the closed second end.
