- Circumferential direction along the circumference of the container opening 5 ' Circumferential direction along the circumference of the container opening 5 '.
- a major disadvantage of the known closure module is that the construction of the closure module is complex, as a result of the radial forces during the closing process on the container and the
- Container opening act an additional support of the container in the radial direction is required.
- Container opening correspondingly high closure times arise. This has a negative effect on the throughput.
- the known construction of the closure module brings in one
- the use of the known closure module is limited to a round container opening, ie an opening without corners.
- the container opening must be arranged in the operating state in a horizontal plane, that is, for
- Container openings that are not arranged horizontally on the container the construction of the closure module is complex.
- Container opening the folding form on two-dimensional, that is flat
- the object of the invention is therefore to propose an improved closure module for closing a container opening of a container with a lid, which has a simplified structure in which the requirements for the material of the container and / or lid are reduced in terms of their rigidity, wherein the Minimum wall thickness of the container and / or the lid can be reduced, so that with respect to the container and / or the lid material savings and thus a
- Closing times and shorter set-up times can be achieved, in which individual components are easily and quickly replaced, in which the container openings are not limited to round geometries, in which the container opening in the operating state does not have to be arranged in a horizontal plane, in which produced three-dimensional folds can be, so that from the state of the art
- Another object of the invention is to provide an improved
- closure device with a closure module, which has a simplified structure in which shorter closure times and shorter setup times can be achieved, in which the closure module and / or individual components of the closure module are easily and quickly replaced, so that the known from the prior art disadvantages be largely avoided.

- the support unit and the pressing unit are so relative to each other in an axial direction
- Operating state between the support surface and the pressing surface can be pressed together by an axially acting force.
- Container opening which means that in the operating state, the support surface with the container flange over the entire circumference of the container opening is engaged and also the pressing surface with the cover flange over the entire circumference of the cover flange is engaged.
