The two parts abut at one contact face (8,9), At least one part consists of material, contg. a solid lubricant in the region of the contact face. The material, contg. the solid lubricant, is pref. plastics, typically a thermoplastic alloy and may contain extra composite fibres. Alternatively the part may be completely of plastics contg. the solid lubricant. The first part may be a glass container, and the second one a plastics stopper.
