• the present object is achieved by the features of the main claim, in particular from the characterizing part, which have the following special significance.
• a sealing of the container by the closure device is independent of a contact pressure (Pk), which acts from the closure device to the container, in particular the opening edge. Consequently, the sealing element is not pressed between the closure device and the container, in particular the opening edge, in order to seal the container in a sealing manner from above and / or also from the inside.
• Pk contact pressure
• the closure device according to the invention is particularly easy to operate even for weak and awkward or movement-restricted people. Unlike the usual closure devices no pressure (Pk) must be exerted on the closure device, so that nevertheless the container is reliably sealed. Rather, the pressure generated by the own weight of sealing element and possibly closing device pressure on the sealing element sufficient to easily deform this possibly, whereby the sealing element fits exactly to the container geometrically or forms to seal the container sealing.
• the closure device according to the invention is designed self-sealing, since the existing or still resulting internal pressure (Pi) is used to close the container. In this case, the internal pressure (Pi) presses the sealing element against the opening edge, in particular against an inner wall of the opening edge, by additionally deforming the sealing element (which is the existing internal pressure Pi) and pressing it more strongly against the container.
• the sealing element itself has a sealing lip which projects into the opening of the container and sealingly comes to rest on the inner wall of the opening edge by an elastic deformation.
• the sealing lip is loosely against the inner wall of the opening edge, without being pressed by another element, such as the closure device to the inner wall.

• This material has, for example, a hardness of 10 to 90 shore A, in particular 40 to 80 shore A (according to standards DIN 53505 and DIN 7868). Preference is given to a material having a hardness of 70 shore A, since this has hitherto set the best tightness results.
• the material is flexible but also dimensionally stable, this means that the seal retains its basic shape even after deformation in order to obtain the desired sealing effect.
• the sealing element may comprise a dimensionally stable core of harder material which is surrounded by a softer or more flexible material. It is also conceivable dimensional stability by constructive measures such. B. reinforcing ribs, edges or the like. Furthermore, it has proven to be advantageous if the fitting surface of the sealing lip is made smooth in the region of the sealing line.

Otherwise, if the elastic deformations are too great, the sealing element could tend to form wrinkles or creases which are undesirable since this would prevent sealing.
• the contact pressure (Pk) which acts on the container, in particular the opening edge, of the closure device is substantially insignificant for the functioning of the sealing element, so that it is ineffective for the purposes of this application. If the contact pressure (Pk) between the container and the closure device is too high, the sealing element can even be deformed in such a way, for example by wrinkling, that a seal no longer takes place. Consequently, the functioning of the closure device according to the invention does not depend on the contact pressure (Pk) between the container and the closure device.
