Abstract
An opening-force-maximizing device of an underpressure-activated valve for a drinking container (). The device includes a partition wall () enclosing an outlet opening () and being provided with a wall opening () in pressure-sealing contact with an axially movable valve sealing member () being in position of rest. It also includes a continuous membrane () being arranged to the container () and about a valve axis () through the wall opening (). The membrane () has an axial extent and consists of an attachment end () fixedly connected to the partition wall (), and a movable maneuvering end () placed at an axial distance from the attachment end (). The maneuvering end () is arranged in a tensile-force-transmitting manner to said sealing member (). By arranging the membrane () with a maximum longitudinal extent when at rest in its inactive position, and by being arranged radially flexible and deflectable and also being arranged in a manner inhibiting axial stretching, a maximum valve opening force is achieved when underpressure-activated.
