FERMETURE POUR RECIPIENTS, EN PARTICULIER FERMETURE EN MATIERE SYNTHETIQUE POUR BOUTEILLES

摘要

On a surface intended for resting against the container to be closed, the plastic container closure (1) has a covering (6) which is made of soft elastic plastic and is intended to provide a good seal. This covering has a fixed connection to the surface of the closure body. The material of the closure body can be heated far less by microwaves than the material of the covering (6). The container closure is produced by applying a liquid starting material for the covering (6) to a particular region of the closure body and heating it by microwaves. Since the material of the closure body can be heated far less by microwaves, no changes to the material in the closure body are caused during this treatment, but a firm contact of the soft elastic covering (6) with the closure body is produced. <IMAGE>
