Abstract
A glass decorating color is applied to a glass article but is not bonded permanently to the glass. A finely divided heat settable plastic material is applied to the article over the impermanently bonded color and onto glass surface areas beyond the area covered by the color. Heat setting of the plastic material, even though insufficient to permanently bond the color itself to the glass, forms a smooth plastic film over the decoration and fixes the color with respect to the glass surface.
Claims18
A method of permanently decorating a glass container comprising,
- applying to an outside surface region of a preformed glass container a glass decorating color which requires heating to a temperature higher than about 150.degree. F. to bond permanently to the glass surface,
- then, prior to heating said container with the said decorating color thereon to a temperature effective for such permanent bonding to occur, coating a finely divided heat settable plastic onto said glass container, the said plastic being coated over the applied color and extending on said glass surface beyond the surface region on which said color has been applied,
- then anchoring said plastic to said glass container by heating the decorated and thus coated container to set the plastic so that it forms a smooth continuous film,
- and cooling the container,
- the resultant plastic film being supported by and anchored to the surface of said glass container at least over the region beyond that covered by the said decorating color,
- thereby producing a final permanently decorated glass container wherein said film provides a permanent outer covering over said decorating color which encloses and protects the latter on the glass surface, the decorating color being captured between the film and the glass surface and not extending to the outside surface of said film.

A method of permanently decorating a glass container comprising,
- applying to a surface region of a preformed glass container a glass decorating color which is not bonded permanently to the glass surface,
- then coating a finely divided heat settable plastic onto said glass container, the said plastic being coated over the unbonded applied color and extending on said glass surface beyond the surface region on which said color has been applied,
- then heating the thus coated container to set the plastic so that it forms a smooth continuous film which is anchored to the container,
- and cooling the container,
- the resulting plastic film being supported by and adherent to the surface of said glass container at least over the region beyond that covered by the said decorating color,
- the unbonded decorating color being covered and protected by the plastic film,
- thereby producing a final permanently decorated glass container wherein said film provides a permanent outer covering over said decorating color which encloses and protects the latter on the glass surface, the decorating color being captured between the film and the glass surface and not extending to the outside surface of said film.
