Method of identifying a container and/or a finished article obtained from the said container, in particular for medical use
First Claim
1. Method of marking a container (1) for identification purpose for medical or diagnostic use, intended to hold a product (10) of interest, the said container (1) being obtained by a process characterized in that it comprises at least the following steps during which:
- (B) a two-dimensional or three-dimensional marking zone (4), the temperature of which is maintained at a first temperature, is provided in or on the substrate of a blank (2) intended to constitute the said container (1) and, in the said marking zone (4), an identification code (5) is reproduced by illumination (6) of the said marking zone (4) with at least one beam (7) of coherent monochromatic localized electromagnetic radiation to which the substrate is at least partially transparent, the said beam (7) being operated and controlled in order to remove or modify the constituent substrate of the wall (3) and to leave the identification code (5), in positive or negative form, in the said wall so that the said code is readable; and
(C) at least the said marking zone (4) is annealed by heating it to a second temperature strictly above the said first temperature so as at least to reduce the differences in internal tension in the substrate between the said marking zone (4) and the rest of the said wall (3).

Abstract
Method of identifying a container (1) obtained by a process comprising the following steps: (A) starting from a blank (2) of the container (1), at least part of the said container (1) is formed; (B) a two-dimensional or three-dimensional marking zone (4), the temperature of which is maintained at a value below the glass transformation temperature of the constituent substrate, is provided in or on the substrate of the blank (2) and, in the said marking zone (4), an identification code (5) is reproduced by illumination (6) of the said marking zone (4) with at least one beam (7) of coherent monochromatic localized electromagnetic radiation to which the substrate is at least partially transparent, the said beam (7) being operated and controlled in order to remove or modify the constituent substrate of the wall (3) and to leave the identification code (5), in positive or negative form, in the said wall so that the said code is readable; and (C) at least the said marking zone (4) is annealed so as at least to reduce the differences in internal tension in the substrate between the said marking zone (4) and the rest of the said wall (3).

- 11. Container (1) for medical or diagnostic use, intended to hold a product (10) of interest, in divided or undivided solid, gel, powder or liquid form, characterized in that at least one wall (3) of the said container (1) is provided with at least one two-dimensional or three-dimensional marking zone (4) in which at least one identification code (5) is reproduced so as to be readable, said marking zone (4) being provided in the thickness of the wall (3) of the container, at some distance from its internal face (3a) and/or from its external face (3b).
- 12. Container (1) for medical or diagnostic use, intended to hold a product (10) of interest, in divided or undivided solid, gel, powder or liquid form, characterized in that at least one wall (3) of the said container (1) is provided with at least one two-dimensional or three-dimensional marking zone (4) in which at least one identification code (5) is reproduced so as to be readable, said marking zone (4) being provided on the internal face (3a) of the wall (3) of the container (1), the said part being intended to hold or containing the product (1) of interest.
