Abstract
The invention disclosed pertains to a method and article formed thereby, wherein a container is encased in a multi-part plastic functional coating to enhance the strength of the container; and, in the case of frangible materials used in making pressurized containers, such as glass bottles for beer and carbonated beverage products, retain fragments upon breakage. The functional coating is formed by first applying organic plastic materials over localized exterior surface areas of the container, e.g. the neck or neck and bottom regions of a bottle, or over the whole exterior surface area of the container so that the plastic material conforms to the surface areas in snug fitting relation. This is followed by placing a sleeve of heat shrinkable thermoplastic material over the exterior body of the container overlapping the first plastic coating at least in one area and heating the sleeve to shrink it over the first coating and the container joining the two plastics together. In another embodiment, the sleeve is first shrunken on the container and the organic plastic applied to overlap the sleeve in whole or in part and all or part of the remainder of the container'"'"''"'"'s surface not covered by the sleeve so as to encapsulate the bottle or sleeve and bottle.

-
6. The article of claim 1, wherein said plural cover members include a first cover member comprising a preformed sleeve of heat shrinkable plastic material shrunken onto the body of the bottle in snug fitting encircling relationship, and an outer second member on the exterior glass surface of the bottle and overlying at least a portion of said sleeve which comprises a plastic layer formed in situ on the exterior surface of the bottle and at least a portion of said sleeve, said second member covering all of the exposed outer glass surface area of the bottle and at least a portion of said sleeve.
-
7. The article of claim 6, wherein said outer second member covers all of the exterior surface area of said sleeve.
-
8. The article of claim 1, wherein said plural cover members include a first cover member comprising a preformed sleeve of heat shrinkable plastic material shrunken onto the body of the bottle in snug fittiNg encircling relationship, and an outer second member on the exterior glass surface of the bottle and overlying at least a portion of said sleeve which comprises a plastic layer formed in situ on the neck surface of the bottle and at least a portion of said sleeve, the composite of said sleeve and outer plastic layer encapsulating substantially all of the exterior area of the bottle.
-
9. The article of claim 1, wherein said second preformed member of the plural cover members is comprised of a formed heat shrinkable thermoplastic material.
-
10. A container having a bottom end wall and a side wall connected with said bottom end wall, the improvement therein which comprises at least a portion of the side wall encased in a plastic film formed in situ on said wall and a portion of the side wall and bottom end wall of the container encased in a separate plastic sleeve member formed of contractible plastic sheet material encircling said container wall and shrunken thereon and in overlapping engagement with said plastic film, whereby the major outer surface of the container is encased by said in situ film and shrunken sleeve member.
-
11. The container of claim 10, wherein said shrunken plastic sleeve member is formed of a cellular, shrinkable, polymeric material that is shrunken in overlapping engagement with said plastic film.
-
