A container assembly includes a container and a closure that has plural vents formed proximate its top member, preferably at a transition between the top member and the skirt. The closure includes a feature that spaces apart an edge of a liner, outside of which the vents are formed, and provides tamper protection. The closure and the container neck form a top and corner seal therebetween while the closure is in a fully closed position, and provide a gap when the closure is in a vented position. P gases within the container escape through the gap and the vents when the closure is unthreaded from the fully closed to the vented position. The vents may be configured such that the vent outlet is oriented substantially vertically to vertically direct the outbound gases to prevent closure blow-off and to avoid impinging against a user's hand.

[What is claimed is:] [1.]a top member and a circular skirt downwardly depending therefrom, the closure including a vent hole that has an inlet formed on an interior surface of the closure and an outlet formed on an exterior surface of the closure, the skirt having a second thread formed thereon that is in cooperation with the first thread to enable the closure to move between a fully closed position and a vented position, the closure and the container rim forming a seal therebetween in the fully closed position and enabling venting through the vent holes in the vented position, whereby internal pressure of the container is released through the vent holes as the closure is unthreaded from the fully closed position; the closure further including a liner disposed on an interior surface of the top member, the vent holes formed substantially outside a perimeter of the liner, the interior surface of the top member and the upper rim contacting opposing sides of the liner to seal the container in the closed position, the upper rim being spaced apart from the liner in the vented position to enable communication between the vent hole and an interior of the container in the vented position;the top member and the skirt forming a ridge peak on the inner surfaces thereof, the ridge peak conforming an edge of the liner to space the liner apart from the vent hole.
