Abstract
A closure comprises a hub with a central opening and a head pivotally connected to the hub, the head sealing the central opening when in a closed position. A lip seal relief is defined by a stepped surface between the head and the hub so that when the head is closed, the relief or clearance is provided between the head and hub inhibiting damage to a seal.
