Abstract
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.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
214 words
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° 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.
Claim 2
Independent Claim
214 words
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° 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.
Claim 3
Dependent Claim
48 words
The method of claim 1 wherein said plastic is set by heating to a temperature below the temperature necessary for said decorating color to be permanently bonded to said glass surface, the decorating color being held in place on said glass surface by the plastic film over it.
Claim 4
Dependent Claim
50 words
The method of claim 2 wherein said decorating color is an inorganic screen decorating color which must be heated to a temperature above the temperature at which said plastic is set, to be bonded permanently to said glass surface, and which remains unbonded to the glass under the plastic film.
Claim 5
Dependent Claim
78 words
The method of claim 1 wherein said decorating color includes a glass frit component which must be melted at a temperature above 800° F. in order for said decorating color to be permanently bonded to said glass surface, and wherein said plastic is set at a temperature below the temperature necessary to cause said frit component to be permanently bonded to said glass surface, the decorating color being fixed with respect to the article by the plastic film.
Claim 6
Dependent Claim
36 words
The method of claim 1 wherein said decorating color is an organic ink and is permanently bonded to the glass surface during the same heating of the plastic coated article by which the plastic is set.
Claim 7
Dependent Claim
17 words
The method of claim 1 wherein said decorating color is applied by a silk screen decorating process.
Claim 8
Dependent Claim
14 words
The method of claim 1 wherein said decorating color is applied by offset printing.
Claim 9
Dependent Claim
54 words
The method of claim 1 wherein a multiplicity of differently colored decorating colors are applied to said container sequentially, all such sequentially applied colors but the last being permanently bonded to the container before the last color is applied, the last such decorating color being imperfectly bonded when said plastic is coated over it.
Claim 10
Dependent Claim
86 words
The method of claim 8 wherein all of the decorating colors but the last to be applied are thermoplastic, and wherein the last to be applied is a ceramic which requires heating to a temperature of at least 800° F. to become durably bonded to the glass surface, and wherein said ceramic is not heated to a temperature sufficient to bond it to the glass surface, all of the decorating colors being sandwiched with respect to the glass surface by the resulting plastic film over them.
Claim 11
Dependent Claim
17 words
The method of claim 1 wherein said plastic is a resin in finely divided discrete particle form.
Claim 12
Dependent Claim
20 words
The method of claim 10 wherein said plastic is an ionic copolymer of an alpha olefin and an alpha-beta olefin.
Claim 13
Dependent Claim
11 words
The method of claim 1 wherein said plastic is a plastisol.
Claim 14
Dependent Claim
20 words
The method of claim 1 wherein said plastic is heat settable at a temperature between about 350° and 500° F.
Claim 15
Dependent Claim
55 words
The method of claim 1 wherein said coating is carried out by the electrostatic fluidized bed process, the article, with the decorating color applied to it but imperfectly bonded thereon, being coated as it passes in proximity to a fluidized bed of particles of said plastic which particles are electrostatically charged oppositely from said article.
Claim 16
Dependent Claim
51 words
The method of claim 1 wherein said container is heated after said decorating color has been applied to it, such heating being sufficient for said container to be rendered conductive for said coating to be applied by an electrostatic process but insufficient to permanently bond said decorating color to said container.
Claim 17
Dependent Claim
23 words
The method of claim 1 wherein said plastic is a finely divided resin and is applied by an electrostatic dry powder spray process.
Claim 18
Dependent Claim
44 words
The method of claim 1 wherein said plastic is a plastisol, said article being dipped into a bath of said plastisol after said decorating color has been applied to said surface region and while said decorating color is impermanently bonded to said glass surface.
Claim 19
Independent Claim
192 words
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.
