• a) creating a one-piece casing having an inner surface and an outer surface, the casing being flexible, the casing having a housing and a flap, the flap being designed for placement in a folded-in position in which the casing has an interior volume and a slit extending between the housing and the flap, the slit being one continuous slit, and
• b) attaching a sealing device on the housing and the flap at the slit
• wherein creating the casing during operation a) comprises:
• creating the housing with a main face, a first longitudinal face, a second longitudinal face, a first transverse face, and a second transverse face,
• creating the flap in substantially flat form, and
• the flap is designed to be placed in an open position in which the flap is substantially in the extension of the second transverse face and in the folded-in position, the slit extending around the flap and only along the first longitudinal face, the second longitudinal face, and the first transverse face.
