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 containing a consumable beverage. The closure comprises a closure base which is threaded onto the outlet opening of the bottle, and a removable overcap which is pivotally connected to the closure base. The closure base includes a spout having a self-sealing dispensing valve 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 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.
