Abstract
Abstract A dispensing assembly includes a seal that is induction-bonded to an outlet of a container. A cap is detachably connected to the container over the seal to protect the seal during shipping. Once the cap is removed, the seal can be peeled away from the outlet. The absence of the seal can be observed when an attempt is made to reconnect the cap to the container after the seal has been removed.
