Definitions

  • the invention relates to the field of closure systems for vessels, in particular bottles, and relates to a closure for closing a vessel opening.
  • the closure comprises a first closure body with a receiving opening and a second closure body with a closure member for closing the vessel opening in a direction to the vessel opening direction, and a closing element adjoining the closure member for externally encompassing a neck region of the vessel opening, wherein the second closure body in the mounted state of Closure is at least partially guided through the receiving opening of the first closure body and is surrounded by this, and the first closure body includes a pressing member, wherein the closure body are configured so that the pressing member in the assembled state of the closure occupies a contact position in which the holding member of the second Closure body is pressed against a neck region of the vessel opening taking a closed position.
  • a closure with the features of the preamble of claim 1 is made GB 607,485 known.
  • closure system for vessels such as bottles and containers are known from the prior art. Which closure system is ultimately preferred depends on the requirements placed on such a closure system. An important criterion is, for example, reclosability. So it is for certain applications z. For example, in the area of the food industry or in the field of pharmacy and medicine, it is stipulated that a closure may not be re-closable. Thereby is z. B. achieved that any residual amounts after opening the vessel can no longer be stored. Furthermore, the containers with the original closure can no longer be used for the storage of other substances.
  • the crown cap is a circular piece of sheet metal, which is provided with a sealing insert. The edge of the sheet metal piece is bent crown-shaped when closing the bottle.
  • the bottle cap serves to seal beverage bottles airtight.
  • a bottle opener is needed to open a bottle capped by a bottle cap.
  • the bottle cap is irreversibly damaged, so that it is no longer suitable for reclosing.
  • closures In the consumer goods sector, the closures must be easy to use, especially for older and handicapped people. In this context, the criterion of opening the shutter with or without tools also plays a role. It goes without saying that a closure that can be operated without a tool has a significant advantage by eliminating the need to carry an opening tool.
  • Tool-free to open closures are z. B by screwing or pulling on a closure part or by folding a closure part open.

As a result of this process, the lamellae are pressed against the neck of the bottle, with projections on the lamellae engaging under a shoulder formed on the bottleneck. As a result, the closure is secured against axial displacement in the opening direction. To open the closure, the cap is removed again.
