A filled and reclosable pressure vessel, in which a body is filled with a fluid, closed with a lid element (10, 100) and subjected to a heat treatment, with a lid surface (11, 110), and a closure (14) made of plastics as a lid element (10, 100), and at least one seal (16) arranged on the closure (14), the lid element (10, 100) being arranged in such a way that the closure (14) faces the interior of the sealed pressure vessel, wherein the lid surface (11, 110) and the closure (14) are arranged in such a way that the lid surface (11, 110) has a first distance (a1) from a first reference plane (E1) which substantially extends through the at least one sealing surface (16a) on the first surface (111) of the lid surface (11, 110), and the closure (14) extends at a second distance from a second reference plane which extends through the at least one seal (16), with the first distance (a1) being chosen to be larger than the second distance.
