Venting valve-type closure for beverage container
First Claim
1. In combination with a beverage container having an outlet neck centered on an axis, a closure comprising:
- a mount secured to the neck;
a valve body formed withan outwardly open passage extending along a passage axis generally coaxial with the outlet-neck axis and having an outwardly open outer portion and an inwardly open inner portion,a transverse partition completely blocking axial flow through the passage between the portions, andradially open inner and outer ports immediately flanking the partition in the respective portions, the mount being formed with an axially extending and radially inwardly open bypass groove level with the partition and with the ports, the body being pivotally displaceable in the mount about a valve-body axis generally coaxial with the passage axis and outlet-neck axis between an open position and a closed position and through an intermediate position, the ports being positioned so as to both open into the bypass passage in the open position and being angularly offset therefrom in the closed position, whereby the partition blocks flow through the passage in the closed position, allows free flow through the passage in the open position, and limits flow through the passage in the intermediate position.

Abstract
A closure used on a beverage container has an outlet neck centered on an axis. The closure has a mount secured to the neck and a valve body formed with an outwardly open passage extending along a passage axis generally coaxial with the outlet-neck axis. This body is pivotally displaceable in the mount about a valve-body axis generally coaxial with the passage axis and outlet-neck axis between an open position and a closed position and through an intermediate position. Structure on the valve body and mount block flow through the passage in the closed position, allow free flow through the passage in the open position, and limit flow through the passage in the intermediate position.

15. In combination with a beverage container having an outlet neck centered on an axis, a closure comprising:
-
a mount secured to the neck; a valve body formed with an outwardly open passage extending along a passage axis generally coaxial with the outlet-neck axis and a core part forming the passage and made of a soft plastic and an outer part forming the formation and made of a hard plastic, the body being pivotally displaceable in the mount about a valve-body axis generally coaxial with the passage axis and outlet-neck axis between an open position and a closed position and through an intermediate position; and means including structure on the valve body and mount for blocking flow through the passage in the closed position, for allowing free flow through the passage in the open position, and for limiting flow through the passage in the intermediate position.

16. In combination with a beverage container having an outlet neck centered on an axis, a closure comprising:
-
a mount secured to the neck; a valve body formed with an outwardly open passage extending along a passage a axis generally coaxial with the outlet-neck axis and a radially open port, the mount being formed with a radially inwardly open groove opening into the container, the body being pivotally displaceable in the mount about a valve-body axis generally coaxial with the passage axis and outlet-neck axis between an open position and a closed position and through an intermediate position; and means including structure on the valve body and mount for blocking flow through the passage in the closed position, for allowing free flow through the passage in the open position, and for limiting flow through the passage in the intermediate position, the port being aligned radially with the groove in the open position. - View Dependent Claims (17, 18, 19)

20. In combination with a beverage container having an outlet neck centered on an axis, a closure comprising:
-
a mount secured to the neck; a valve body formed with an outwardly open passage extending along a passage axis generally coaxial with the outlet-neck axis and an outer end formed with two diametrally oppositely extending formations facilitating gripping and rotating the valve body, the body being pivotally displaceable in the mount about a valve-body axis generally coaxial with the passage axis and outlet-neck axis between an open position and a closed position and through an intermediate position; and means including structure on the valve body and mount for blocking flow through the passage in the closed position, for allowing free flow through the passage in the open position, and for limiting flow through the passage in the intermediate position.
