Abstract
Abstract The invention relates to a medium-inflatable body provided with an opening that can be closed off with a valve, comprising: an outer plate with a medium inlet which is arranged on the body around the opening such that the medium inlet lies opposite the opening; and an inner plate provided with a valve body which is connected to the inner plate via laterally extending wings, wherein medium passages lie between the wings, and which is provided with a central valve body portion wherewith the medium inlet in the outer plate is closable with enclosing of a flat sealing ring, wherein a valve body seating and an outer plate seating, which come into contact with the sealing ring, are each provided with a sharp peripheral rib of mutually differing diameter located coaxially around the medium inlet, and to a packaging and to a valve.
