  • Patent number: 12227337
    Abstract: A closure cap for closing the pouring opening of a container, has a cylindrical threaded part with an open edge and an inner thread to interact with an outer thread of a container neck of the container, a security ring held on a protrusion on the container neck, a plurality of security webs releasably connecting the security ring to the open edge, a first holding strip with a first end rigidly connected to an open edge of the threaded part and a second end rigidly connected to the security ring, and a second holding strip with a third end rigidly connected to an open edge of the threaded part and a fourth end rigidly connected to the security ring. The second end on the circular path of the security ring is in a substantially diametrically opposed manner to the fourth end before the threaded part is opened for the first time.

  • Publication number: 20240375837
    Abstract: The invention relates to a container closure for closing a pouring opening of a container which is filled with a liquid, having: a closure cap, which has a free edge, a shell and a top plate; a tamper-evident ring, which is designed to be retained form-fittingly on a container neck of the container; and a retaining element having a first and a second end, the first end being firmly connected to the free edge of the closure cap and the second end being firmly connected to the tamper-evident ring. The closure cap is transferable from a closure position, in which it closes the pouring opening, into an open position, in which it fully opens up the pouring opening, and vice versa. An adhesion surface for improving the adhesion of liquid is provided on the inner side of the top plate coming into contact with liquid.
