Abstract
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.
