ABSTRACT Containers such as drink bottles are provided with closure caps having plastics guarantee strips shrink fitted on to the containers which can be torn off when the container is first opened. The present invention provides a process for the production of such closures in which guarantee strips are simultaneously and continuously shrink fitted on a plurality of containers by passing the containers provided with the closure caps through transport means wherein they are both moved forwardly and also rotated about their own axis. A slot-like nozzle arranged in the plane of movement of the guarantee strips and extending over the entire forward feed distance directs a jet of hot gas on to the guarantee strips. A transport screw is particularly suitable for producing the forward movement of the containers in the transport means, while the containers are pressed against a wall on which they roll and which has a high coefficient of friction. Rotation of the screw, moves the containers forwardly in the transport means, simultaneously rotates them about their own axis rolling them against the wall. A plurality of containers can be passed simultaneously along the length of the slot-like nozzle, depending on the length of the transport means.
