DISPENSING CLOSURE FOR PACKAGE CONTAINING A CONSUMABLE BEVERAGE

摘要

A sealing and dispensing closure for the outlet opening of a package, such as a flexible plastic bottle (12) containing a consumable beverage. The closure comprises a closure base (20) which is threaded onto the outlet opening (14) of the bottle, and a removable overcap (40) which is pivotally connected to the closure base . The closure base includes a spout (25) having a selfsealing dispensing valve (28) therein which is movable from a lowered closed position to a raised open position by an increased pressure in the bottle resulting from the squeezing of the bottle. The valve is positioned at a recessed location within the spout so as to preclude access to the valve by the consumer when the valve is lifted to its raised open position, and the overcap includes a post (50) which seats in the upper end of the spout when the overcap is mounted on the closure base, and so as to form a hermetically sealed chamber above the valve which prevents the valve from lifting to its raised position in the event the bottle is inadvertently squeezed.
