This invention relates to a method for producing a composite container having a body label or tubular sleeve mounted thereon adapted to be shrunken onto exterior surface areas of a cylindrical container. The tubular sleeve is preformed of thin flexible thermoplastic material and may be flat-folded until ready for use when it is fully opened and conveyed in axial registry with the container inverted therebeneath. The sleeve preform of heat-shrinkable plastic material is telescopically assembled onto the inverted container while the latter is conveyed through a coincidental aligned path. The container preferably consists of a hollow glass or plastic container held invertedly by its neck portion with the tubular preform made slightly larger in diameter to surround the body and neck portions of the container. The tubular sleeve preform is held fully opened and is then transported downwardly in telescopic relation when in axial alignment with the inverted container. The opened sleeve and upright inverted container are continuously moved in synchronism in a coincidental lineal path for such sleeve mounting in temporary relation on the container body and neck where it is adapted to controlled heat-shrinking in place in permanent conforming arrangement.

The method of labeling a container having a base, a first body portion adjacent the base having an exterior surface of predetermined circumference and a second body portion extending from said first body portion having an exterior circumference less than said predetermined exterior circumference of said first body portion, said method comprising the steps of providing a preformed, tubular sleeve of preprinted, heat-shrinkable, organic, thermoplastic, thin film material having a circumference slightly greater than the predetermined exterior circumference of said first body portion of said container, opening said sleeve into open tubular arrangement, retaining the container in an inverted position, transporting the said container and sleeve in vertically-aligned relation with said open sleeve retained over said container, telescoping said sleeve downwardly over the exterior surfaces of said body portions of said inverted container, and heating said sleeve to shrink it into snug essentially wrinkle-free engagement with said exterior surfaces of said body portions therebeneath.
