  • Patent number: 7490621
    Abstract: A method for producing a tapping valve formed as a plastic injection-molded part for plastic or metal shipping and storage tanks for liquids, wherein, in a first process step, the screw cap for screwing the valve onto the outlet connection of a liquid tank is produced in a first injection mold, the screw cap is then placed in a second injection mold, and in a second process step, the valve body is produced in the second injection mold in such a way that the inlet connection of the valve body passes through the opening of the ring shoulder and the threaded hole of the screw cap with clearance, and the collar of the inlet connection of the valve body is located inside the screw cap. In a second method, the valve body and its inlet connection are injection-molded as separate parts in a first process step, and in a second process step, the inlet connection, with a screw cap slipped onto it, is welded onto the valve body.

  • Patent number: 6832693
    Abstract: A transport and storage container for liquids has an inner plastic container having an upper bottom with a fill socket, two sidewalls, a front wall with an outlet socket at the lower edge, a back wall, and a lower drainage bottom slanted toward the outlet socket. A pallet-shaped underframe has a support bottom for receiving the lower bottom of the inner container. The front wall of the inner container has a dome-shaped bulge where the outlet socket is arranged. Two bottom portions are arranged on opposed sides of the bulge and ascend from the lower bottom toward the front wall and the corner areas adjoining the front wall or toward the front wall and the sidewalls and the corner areas adjoining the front wall and the sidewalls.
