A container neck supports a disc which presents an information. The disc is not visible until a container cap is removed. The information may have a warning which is critical to the use of the container or its contents. Because the information is presented as a surprise to the user who removes the cap, the user is more likely to take notice and therefore heed what the information presents. Such understanding by the user may be critical to the successful use of the contents and may prevent a dangerous situation from arising such as ingesting an improper medication. It has been shown through statistical testing that a user is more likely to take heed of a hidden message visible only upon removal of the cap, than a similar message presented on a disc or other label that is visible prior to removal of the cap.
