A closure is for a container, for example a beverage container. In some examples the closure comprises an outer portion connectable to an opening of the container, an axially actuatable inner portion having a sealing member for restricting fluid flow through the closure with the inner portion in a first position and allowing fluid flow through the closure with the inner portion in a second position axially displaced relative to the outer portion, and an annular membrane connecting the outer and inner portions and configured to provide a returning force to resiliently bias the inner portion towards the first position. A beverage container comprises a closure. A method is for operating a closure.

Closure for a container, beverage container and a method of operating a closure

A multifunctional sealing device for a valve structured for opening of a discharge conduit by virtue of upstream-directed movement of a sealing body relative to the discharge direction. The distinctive characteristic of the invention is that the sealing body is of a radially flexible arrangement; wherein the discharge conduit is provided with at least one storage seal seat for sealing reception of the sealing body when the valve is in a storage mode, and also at least one utility seal seat for sealing reception of the sealing body when the valve is in a closed utility mode; wherein the at least one utility seal seat is provided upstream of the at least one storage seal seat; and wherein both the storage seal seat and the utility seal seat are structured for sealing against the sealing body during downstream-directed movement of the sealing body.

Multifunctional seal device for a valve for a drinking receptacle

A method and device for controlling the flow of liquid from drinking containers, wherein a membrane is movably connected to a valve to form a valve, controlled by negative pressure, for liquid from a drinking container, the force resulting from the pressure difference (P&#x2212;P) across the membrane, opening the valve, even by positive pressure (P) within the drinking container, caused by a carbonated refreshing drink, for example.

Valve device for a drinking container and a method for using the valve device

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.

An underpressure-activated valve device for a drinking container (). The device consists of an outer membrane () and an inner membrane () that are placed at an axial distance from one another, and their peripheral attachment areas are pressure-sealingly interconnected, causing a reference pressure chamber () having at least one vent () to an ambient pressure Pto exist between the membranes (). One membrane () is fixedly connected to a flow pipe (), and the other membrane () is provided with a membrane opening () within which the pipe () is movably arranged. The membrane opening () is associated with a primary sealing body () for sealing against fluid flow via the pipe (), and with a secondary sealing body () for sealing between the chamber () and an internal pressure Pin the container (). Both sealing bodies () are placed in pressure-sealing contact with the pipe () when the valve device is in an inactive position of rest, while at least the primary sealing body () is placed in an open position when the valve device is in an active position.

Valve device having two membranes for a drinking container

The present invention regards an underpressure-activated valve mechanism for controlled dispensing of fluids, including liquid food articles, from a receptacle. When the user applies sufficient suction force (P) across a pressure comparative diaphragm zone a valve opening force is applied to a valve area that has a force connection with the diaphragm zone. When the suction force ceases the valve area closes and remains closed, even in the event of overpressure (P) in the receptacle.

Device for underpressure-activated dispensing of fluids

This invention concerns a valve for an underpressure-activated outflow mechanism for a drinking receptacle (). The valve includes a valve head () and a valve seat (), in which the valve seat () is arranged in force-transmitting connection with a membrane (), whereas the valve head () is fixed to the remaining structure via at least one stay ().
