A CLOSURE ASSEMBLY AND MANUFACTURING METHOD

摘要

A closure assembly comprises an article (1) forming a tubular neck (2) around a product passage ( 3 ) in said article. The neck forms a mouth at a top end of said product passage. The assembly further comprises a rotational cap (20) that is injection moulded of plastic material and that is secured on or to be secured on said neck of the article. The cap seals the product passage in closed position of the cap on said neck, and the cap - for removal of the cap from the neck of the article by a user to open the product passage - is adapted to be manually rotated from the closed position in an opening direction.
