Abstract: A data carrier extends along an extension direction (E) and comprises at least one carrier body and at least one processing layer. The processing layer, at least in an unprocessed state of the processing layer, comprises one or more reactive elements and one or more unreactive elements. The reactive elements are configured to interact with impinging electromagnetic radiation (R) upon a processing of the processing layer. The processing layer, in a processed state of the processing layer, comprises one or more reacted elements being generated from the reactive elements. The processing layer in the processed state furthermore comprises one or more further reacted elements being generated from one or more of the unreactive elements upon the interaction of the reactive elements with the impinging electromagnetic radiation (R) and furthermore comprises one or more unreactive elements remaining non-interacting.

Abstract: Provided is a data carrier of significantly improved level of security that introduces only a minor modification into their manufacturing process. Other embodiments disclosed. In a first aspect a data carrier is provided, wherein the data carrier comprises at least one carrier body, at least one printing layer, at least one marking layer, and at least one security element. The carrier body comprises a top surface, wherein the printing layer is arranged on the top surface of the carrier body. The printing layer and the marking layer are arranged at least partially above one another with respect to an extension direction. The marking layer is configured to interact with impinging electromagnetic radiation such, that a marking element is generated in the marking layer upon the irradiation of electromagnetic radiation.

Abstract: Disclosed is a for forming a container with multiple walls by blow molding or stretch blow molding of a preform, including a blow-molding phase followed by a degassing phase, beginning at a moment, of the formed container, to bring t:s pressure back to the ambient pressure. The method also includes: a continuous measurement of the pressure prevailing in the neck during the degassing phase; the determination of the length of time that has elapsed between the beginning of the degassing and the attaining of a reference pressure in the neck; the comparison of the length of time that has elapsed with a theoretical length of time that is necessary so that the reference pressure is attained in the neck; and maintaining the locking of the mold if the length of time that has elapsed is less than the theoretical length of time.

Abstract: Plastic container (1), characterized in that it comprises: a rigidified body (5), a bottom (8) extending to a lower end of the container (1) and comprising: an annular base (9) extending substantially perpendicular to the body (5) in the prolongation thereof; an annular step (10) extending from the base (9) towards the interior of the container (1), a recess (12) at the center of the bottom (8) projecting towards the interior of the container (1), a deformable annular membrane (11) in the shape of a spherical cap extending substantially perpendicular to the body (5) between the step (10) and the recess (12).
