DESICCANT STOPPER

摘要

The invention suggests a desiccant stopper suitable for use with a bottle of pills or the like, which stopper is of a thermoplastics material and is in the form of a pot at least one end face of which is made from a fibrous fabric sheet (14) of a plastic material attached around its periphery to either the body (12) of the pot or to a lid (13) for the pot body (12), and wherein the attachement is effected by the sheet (14) being embedded within the material of the body (12) or lid (13), or both. It also proposes two methods by which such a structure can be manufactured, one involving holding the sheet (14) in place while the body (12) or lid (13) material is injection-moulded around it, the other involving sonic fusion of the body/lid material around the sheet (14).
