Title: METHOD FOR THE PRODUCTION OF A LAYER OR A PATTERN FOR COATING THE INNER SURFACE OF A RECEPTACLE, AND RECEPTACLE OBTAINED BY A METHOD OF SAID TYPE
Abstract:
The invention relates to a method for producing a neutral barrier layer for coating the inner surface of a receptacle for holding products that are biocompatible for humans and/or animals, and to the receptacle obtained by said method. According to the invention, a solution is formed that contains at least one solvent, water, at least one complexing molecular alkoxysilane precursor, at least one surfactant, at least one pigment and/or coloring agent, and a catalytic acid, the complexed solution, which is undergoing hydrolysis and condensation, is homogeneously applied to at least one portion of the inner surface of the receptacle, the applied solution is dried at a specific drying temperature such that a layer is formed which is opaque, translucid and/or forms a particular pattern, and the receptacle is conveyed away, stored and filled with the product.
