Abstract
The closing of packing containers, e.g. bottles for beer or refreshing beverages, is achieved by means of metal or plastic caps. A cap which is easy to handle and which is reclosable is disclosed. A substantially conventional cap body of flexible plastic material is provided with locking devices in the form of integrated lever arms, which can be maneuvered by means of a ring surrounding the cap body. The locking devices in closed position rest against a bulge located around the neck of the bottle and can be maneuvered with the help of the ring to an open position in which they permit the unhindered removal or replacement of the cap.
