A valved container assembly comprising: a container for containing a fluid, the container extending in an axial direction and having at least one venting opening at a front end and at least one dispensing opening; a valve disposed in the container; and a plunger element disposed axially rearward of the valve, the plunger element being axially moveable in the container and defining a first volume in the container between the plunger element and the valve, where the plunger element is configured to increase the pressure of a fluid in the first volume upon axial movement relative to the valve; where the valve comprises: a permanent seal forming a fluidic seal with an interior of the container around a periphery of the valve between the at least one venting opening and the first volume; and a resilient seal that is axially rearward of said permanent seal and is moveable between a sealing configuration and an open configuration; wherein in the sealing configuration the resilient seal forms a fluidic seal with the container between the at least one dispensing opening and the first volume; in at least one axial position of the valve in the container when the resilient seal is in the open configuration the first volume is fluidly connected to the at least one dispensing opening; characterised in that, the resilient seal comprises one or more flexible elements (18a, 18b) configured to flex upon fluid pressure in the first volume exceeding a predetermined pressure threshold so as to move the resilient seal from the sealing configuration to the open configuration to allow fluid to bypass the resilient seal; and wherein the at least one axial position of the valve in the container in which the first volume is fluidly connected to the at least one dispensing opening when the resilient seal is in the open configuration includes the forwardmost axial position of the valve in the container. a container for containing a fluid, the container extending in an axial direction and having at least one venting opening at a front end and at least one dispensing opening; a valve disposed in the container; and a plunger element disposed axially rearward of the valve, the plunger element being axially moveable in the container and defining a first volume in the container between the plunger element and the valve, where the plunger element is configured to increase the pressure of a fluid in the first volume upon axial movement relative to the valve; where the valve comprises: a permanent seal forming a fluidic seal with an interior of the container around a periphery of the valve between the at least one venting opening and the first volume; and a resilient seal that is axially rearward of said permanent seal and is moveable between a sealing configuration and an open configuration; a permanent seal forming a fluidic seal with an interior of the container around a periphery of the valve between the at least one venting opening and the first volume; and a resilient seal that is axially rearward of said permanent seal and is moveable between a sealing configuration and an open configuration; wherein in the sealing configuration the resilient seal forms a fluidic seal with the container between the at least one dispensing opening and the first volume; in at least one axial position of the valve in the container when the resilient seal is in the open configuration the first volume is fluidly connected to the at least one dispensing opening; characterised in that, the resilient seal comprises one or more flexible elements (18a, 18b) configured to flex upon fluid pressure in the first volume exceeding a predetermined pressure threshold so as to move the resilient seal from the sealing configuration to the open configuration to allow fluid to bypass the resilient seal; and wherein the at least one axial position of the valve in the container in which the first volume is fluidly connected to the at least one dispensing opening when the resilient seal is in the open configuration includes the forwardmost axial position of the valve in the container.
