摘要： A plastic screw cap (100) for large containers, comprises a cylindrical outer jacket (1) having a first internal thread (2) of larger diameter and a head plate (3), which at least partially closes the outer jacket (1) at an axial end, wherein the head plate has an opening (4), which accommodates a removal sleeve (20) having an approximately cylindrical inner jacket having a second internal thread (12) of smaller diameter, which inner jacket protrudes into the interior of the outer jacket, wherein the head plate (3) and the removal sleeve (20) are integrally joined to each other. In order to provide caps of the same functionality that can be produced more simply, the outer jacket (1), according to the invention, together with the head plate (3) on the one hand and the removal sleeve (20) together with the internal thread (2) on the other hand are produced separately from each other by injection molding and are joined to each other fixedly and tightly by welding in order to form the complete screw cap (100).

摘要： The invention concerns a plastic closure for fitting on to the neck of a liquid container in positively locking and sealed relationship comprising a head plate (1) provided for covering a container opening and an outer seal (7) which is circumferential along the edge of the head plate (1) and is provided for engagement with the outside of a container neck (20) defining the container opening, and an inner seal (5) which is circumferential within the outer seal (7) and parallel thereto and which is provided for engagement with the inside of the container neck, wherein the outer and the inner seals (7, 5) respectively extend approximately perpendicularly or slightly inclined from an inside (11) of the head plate (1). To provide a closure and also a container having a closure which generally prevent the closure being blown off under a high positive pressure it is proposed according to the invention that the outer seal (7) has a weakened region (6, 6′, 6″) in at least one circumferential portion so that the outer seal (7) becomes unsealed at a lower internal positive pressure than when the outer seal is of a configuration without the weakened region.
