Dispenser cap for storing and dispensing carbonated beverages from a container with: - a lower housing part with a discharge nozzle, - the shape of the inner surface of the spout is chosen so that it fits snugly against the neck of the container, - an upper housing part, which is connected to and interlocking with the lower housing part - the housing is equipped with a control lever, - a valve device and a tube, - the tube is connected to the lower part of the housing, - the control lever is designed as a two-part folding lever, - a plate valve, - the plate valve can be brought into contact with a seat, - the seat is housed in the lower housing part. - the valve stem is pivoted at a bore of the two-part folding lever which is connected to the upper housing part, - the lever parts are hingedly connected to each other, - a resettable elastic element is located on the folding lever, - the upper housing part is provided with stops, - the stops prevent the folding lever from being pressed in a folded position, - a locking mechanism is provided to hold the folding lever in the folded position, - the lower housing part of the dispenser cap is equipped with a control ring, - the end of the housing and the end of the control ring are connected by two parallel strips, with the strips aligned along the axis of the dispenser, - some of the strips are destroyed when the dispenser cap is opened by unscrewing, - a cap is attached to the discharge nozzle of the valve, - the lower housing is additionally equipped with a tooth designed to engage when a dispenser cap with control ring is screwed on, - the tooth prevents the strips between the control ring and the lower housing part from collapsing unintentionally, - the resettable elastic element is attached to the control lever of the upper housing part of the dispenser cap, - the resettable elastic element has the form of two flexible tension members located on both sides of the plate valve, - guides are attached to the lower housing part of the dispenser cap on both sides of the plate valve to fasten the tension members of the dispenser cap to the plate valve, - each guide is designed in the form of a channel, - the shape of the cross-section of the channel corresponds to that of one of the flexible tension members, - the channel of the guide is located at the front end of the cylindrical tube, which is aligned along the axis of the dispenser cap, - the height of the channel varies continuously from a maximum value at the point where the flexible tension members are inserted into the tubular guides, to a minimum value at the point where they exit. -
