ABSORBING SYSTEM IN A CONTAINER

摘要

A polymeric container, for example for food or drink, contains a compartment containing an absorber (20, 38) for scavenging a selected gas or vapour from within the polymeric container. The compartment is formed by welding a polymeric membrane (18, 42) which is permeable to the selected gas or vapour to an internal surface of the polymeric container (30) or its polymeric closure (12, 16, 34) prior to the filling and closure of the container. The polymeric materials comprising the compartment are hence different in nature, and are dielectrically welded together to obtain secure closure of the compartment.
