Abstract

A plastic screw cap includes two cap halves, which are produced as plastic injection-molded parts and have an internally threaded segment and an inwardly directed ring shoulder segment. The two halves of the screw cap can be pushed together, for example, on the inlet connection of the valve body of a flap valve by tongue-and-groove joints. One cap half has two hook-like ends, each of which is provided with an inwardly sloped clamping sidepiece and a groove for receiving the tongues formed on the two ends of the other half of the screw cap.

A plastic screw cap comprising two cap halves on a first component and captively held on the first component, wherein the cap halves each have an internally threaded segment and an inwardly directed ring shoulder segment for making contact with a corresponding collar of the first component, which is to be screwed together with a second component, especially for screwing a valve body of a tapping valve on an externally threaded outlet connection of a plastic or metal shipping and storage tank for liquids and loose bulk material, wherein the two halves are configured to be assembled by means of a hook connection ( 33 ) and a clip connection ( 34 ), wherein a first half ( 32 a ) of the screw cap ( 32 ) has a hook-like end ( 35 ) for hooking into a corresponding insertion hole of a bracket formed on one end of the second half of the screw cap, wherein a boss is formed on the other end of the first half of the screw cap, and wherein the boss is configured to engage radially into a corresponding hole of a bracket formed on the other end of the second half of the screw cap.
