Abstract
A glass container, particularly a bottle, is wrapped in a plastic laminate which is held to the glass by an adhesive. The plastic laminate protects the surface of the bottle from abrasive forces which would diminish the strength of the glass, in combination with the adhesive substantially prevents scattering of the glass, should it be broken, and, because of its structure, provides for application of an attractive graphic design or label which is also protected from abrasion. The plastic laminate includes an inner laminate which is generally opaque, and an outer lamina which is transparent, the label or other graphic design being placed between the lamina.

In a glass container having a straight section, the improvement which comprises adherence to essentially only the straight section of the container of a unitary plastic laminate, the laminate comprising an inner plastic lamina formed of a material selected from the group consisting of polyethylene, ionomers, polyesters, polyvinyl chloride, butadiene copolymers, nylon, polyethylene terephthalate, and cellulosic materials;
- and an outer plastic lamina, of equal size to and in alignment with said inner plastic lamina, formed of a material selected from the class consisting of polypropylene, nylon, polyethylene terephthalate, ionomers, butadiene-styrene copolymers, polyvinyl chloride, and cellulosics;
- with a graphic design between the inner plastic lamina and the outer plastic lamina.
In a glass container having a shoulder portion, with a straight section connected to said shoulder portions, the improvement which comprises:
- a. a plastic film cone on the shoulder portion, said film extending into said straight section;
- and
- b. a plastic laminate adhered essentially only to said straight section including the portions of the cone film which extend into said straight section, said laminate including:
- 1 an inner plastic lamina formed of a material selected from the group consisting of polyethylene, ionomers, polyesters, polyvinyl chloride, butadiene copolymers, nylon, polyethylene terephthalate, and cellulosic materials;
- 2. an outer plastic lamina, of equal size to and in alignment with said inner plastic lamina, formed of a material selected from the class consisting of polypropylene, nylon, polyethylene terephthalate, ionomers, butadiene-styrene copolymers, polyvinyl chloride, and cellulosics;
- and
- 3. a graphic design between said inner and said outer lamina.
In a glass container having a heel portion, with a straight section connected to said heel portion, the improvement which comprises:
- a. a plastic film cup on the heel portion, said film extending into said straight section;
- and
- b. a plastic laminate adhered essentially only to said straight section including the portions of the cup film which extend into said straight section, said laminate including:
- 1. an inner plastic lamina formed of a material selected from the group consisting of polyethylene, ionomers, polyesters, polyvinyl chloride, butadiene copolymers, nylon, polyethylene terephthalate, and cellulosic materials;
- 2. an outer plastic lamina, of equal size to and in alignment with said inner plastic lamina, formed of a material selected from the class consisting of polypropylene, nylon, polyethylene terephthalate, ionomers, butadiene-styrene copolymers, polyvinyl chloride, and cellulosics;
- and
- 3. a graphic design between said inner and said outer lamina.
