Abstract
A single-use cap comprising a cap for connecting to an inlet or outlet of container, connector or port for accessing a material and a piston movably mounted inside the cap. The single-use cap further comprises a first retainer for temporarily holding the piston at a first unused position with respect to the cap. It also has a state converter for converting the piston from the first unused to a second used state when the single-use cap is used to connect to the outlet of the container, connector or port. Once the single-use cap is disconnected from the outlet of the container, connector or port, then a second retainer is activated for permanently retaining the piston in the second used state. The second used state prevents the single-use cap from being reused for connecting to the outlet of the container, connector or port. The second used state causes the piston to block a means for connecting the single-use cap to such an inlet or outlet of container, connector or port, in some instances, such as threads that mate with the container, connector or port.
