| 摘要 |
<p>The invention concerns a flexible tube for storing or dispensing liquid to pasty products containing perfumes, flavours or oxidation-sensitive, provided with a skirt bearing over its whole outer surface a layer having a thickness between 400 and 1500 Å of a material or mixture of materials belonging to the following group: amorphous carbon, hydrogenated or not, nitrogenous or not, oxides, nitrides or carbides or their mixture or their combination of one or several of the following metals (Si, Mg, Al, Ti, Zr, Nb, Ta, Mo, W, V). The coating is carried out using cold plasma, preferably under atmospheric pressure by decomposition of a gas compound and condensation on the substrate assisted by a plasma generated by dielectric barrier discharge or by corona discharge.</p> |
