Container, beverage or foodstuff preparation system, use of said container and method of forming a container

The patent introduces an intermediate member (such as a label or sticker) as a mediator between the flange and the code. The intermediate member is applied to the flange surface, and the code is printed onto this intermediate member rather than directly onto the flange. This simplifies the printing process while ensuring accurate code placement and alignment, as the intermediate member provides a stable, flat printing surface that can be precisely positioned on the flange.

The patent positions the code on the intermediate member which is located on the flange surface, creating a two-dimensional plane that is accessible from multiple angles. The intermediate member is arranged such that the code can be read from various angles around the container, while the membrane extends around the flange to provide hermetic sealing. This spatial arrangement separates the code reading function from the sealing function, allowing both requirements to be satisfied simultaneously.

The patent implements different connection characteristics at different locations of the membrane-flange interface. The membrane is physically connected to the flange at specific localized points or regions to provide sealing, while other portions of the membrane remain free to expand and contract. This localized connection approach allows the membrane to maintain hermetic sealing where needed while preserving its ability to deform and adapt to volume changes in the container.
