FIG10 shows a potential embodiment of the first or second container
The FIG10 shows an example of a container (50) having a flexible wall (51) and an opposite wall (52). The opposite wall defines an internal cavity in which the flexible wall is configured to come into contact. The flexible wall may be thermoformed. The opposite wall may be flexible or rigid. The first part (53) of flexible wall is thermoformed in such a manner to come in contact with a predetermined strain which is greater than the required strain for the second part (54) of the flexible wall. In other terms, the first part (53) of the flexible wall requires a plastic or elastic deformation of the flexible wall which is greater than the second part (54).
