COMBINATION OF A MULTIFUNCTIONAL SEAL DEVICE AND A VALVE FOR A DRINKING RECEPTACLE

摘要

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.
