METHOD FOR FORMING A CONTAINER PROVIDED WITH AN IMPRINT ON AN OVERHEATED AREA |
摘要 |
A method of manufacturing a container having a local recessed or relief impression, from a blank (2) of thermoplastic material. The method includes a heating step in which the blank (2) is exposed to infrared radiation and in which the infrared radiation is monochromatic or pseudo-monochromatic, the intensity of which locally has an extremum in front of a localized zone (11) of the blank, in such a way as to generate a temperature extremum in the zone (11). The method also includes a forming step in which a fluid under pressure is injected into the blank (2) thus heated, and in which the recessed or relief impression is formed at the localized zone (11). |
