Container closure operated by a connecting device

Abstract

A solution is proposed for closing a mouth () of a container () of a liquid (). A corresponding closure () comprises a cap () having fixing means () for fixing the cap () to the container (), a delivery port () for delivering the liquid () from the container (), a valve member () in a closed position wherein the valve member () closes the delivery port (), a cap suction conduit () for suctioning air into the container () during the delivering of the liquid () and a connector () for connecting to a delivery device () of the liquid (), the connector () being in fluid communication with the delivery port (), a slider () slidebly coupled with the cap (), the slider () having a slider suction conduit () for suctioning the air into the container () during the delivering of the liquid () slidebly coupled with the cap suction conduit (), and a frangible element () closing the cap suction conduit () or the slider suction conduit (), wherein the closure () is configured to cause the delivery device () during the connecting thereof to move inwards the container (), in a fixed condition wherein the closure () is fixed to the container (), and thus moving the valve member () inwards the container to an open position, wherein the valve member () opens the delivery port (), and moving the slider () inwards the container to break the frangible element (), thereby putting in fluid communication the slider suction conduit () with the cap suction conduit ().
