Abstract
A sequentially moulded closure arrangement (1) comprising a body (4), which forms the shoulder of a container, such as a tube (2), and defines a dispensing passageway, a cover (5), to seal the dispensing passageway, and a fixing ring (7) to join the body to the container. The cover is connected to the body or the fixing ring by a moulded hinge (6) and the cover and fixing ring are sequentially moulded together as an integral moulding, removing the requirement to assemble the cover, body and fixing ring in a separate assembly operation. The arrangement has further advantages relating to cleanliness and ease of dispensing.
