ABSTRACT:
Disclosed is a tamper-evident closure for a container having a finish opening and including a cap member hingedly connecting to a base member. The base member is threadingly engaged with the bottle finish, and includes an upwardly extending pour spout. A sealing disk is installed in the interior of the pour spout and is secured thereto with a rupturable ring. A pull tab is attached to the sealing disk and, when pulled, causes removal of the sealing disk, threby allowing access to the interior of the bottle container. The cap includes an interior wall which engages the pour spout with a snap fit, providing a liquid-tight and airtight closure therefor.
