Abstract
A lid (16) for closing an opening (12) of a container (10) comprises a sealing foil (26) which is sealable to a fringe (14) of the container opening (12) and the sealing foil (26) is formed tearable and/or is attachable tearable to the fringe (14) of the container opening (12). Therefore, the sealing foil (26) is fixed directly at the lid (16) and the fixing connection (28) is formed between the sealing foil (26) and the lid (16) more weakly than the intended sealing connection (34) between the sealing foil (26) and the fringe (14) of the container opening (12).
Claims13
Closure for a container, comprising:
- a lid for closing an opening of a container;
- and
- a sealing foil having a layer of plastic on one side of the sealing foil for fixation of the foil directly to an interior portion of the lid, and a layer of plastic on the other side of the foil for fixation of the foil to a fringe on an opening of a container,
- wherein the sealing foil is fixed directly to an interior portion of the lid by a detachable fixing connection between the plastic layer of the sealing foil and a portion of the lid, the fixing connection between the sealing foil and the lid being weaker than the intended sealing connection between the sealing foil and the fringe of the container opening.
Packaging, comprising:
- a container with an opening and a closure for the container;
- the closure, comprising:
- a lid for closing the container opening;
- and
- a sealing foil having a layer of plastic on one side of the sealing foil for fixation of the foil directly to an interior portion of the lid, and a layer of plastic on the other side of the foil for fixation of the foil to a fringe on an opening of a container,
- wherein the sealing foil is fixed directly to an interior portion of the lid by a detachable fixing connection and the fixing connection between the plastic layer of the sealing foil and a portion of the lid is weaker than the intended sealing connection between the sealing foil and the fringe of the container opening sealing connection, so that the sealing foil is separated from the lid at least when removing the lid from the container opening for the first time, but the sealing connection is maintained between the sealing foil and the fringe of the container opening.
Process for sealing a container with an opening which is sealable by a lid, comprising the steps:
- providing a lid;
- providing a sealing foil having a layer of plastic on one side of the sealing foil for fixation of the foil directly to an interior portion of the lid, and a layer of plastic on the other side of the foil for fixation of the foil to a fringe on an opening of a container;
- fixing the sealing foil directly to an interior portion of the lid by a detachable fixing connection between the plastic layer of the sealing foil and a portion of the lid;
- closing the container opening with the lid;
- and
- sealing the sealing foil to a fringe of the container opening, by a fixing connection between the sealing foil and the lid is formed, wherein the fixing connection between the plastic layer of the sealing foil and a portion of the lid is weaker than the sealing connection between the sealing foil and the fringe of the container opening.
