Abstract
Abstract 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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
154 words
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.
Claim 2
Independent Claim
154 words
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.
Claim 3
Dependent Claim
33 words
The method in accordance with claim 1, wherein said container comprises a glass bottle having a neck portion, and retaining said bottle in inverted vertical relation by firm retention of its neck portion.
Claim 4
Dependent Claim
29 words
The method in accordance with claim 1, wherein said container comprises a plastic bottle, and retaining said bottle in inverted vertical relation by firm retention of its neck portion.
Claim 5
Dependent Claim
32 words
The method in accordance with claim 2, wherein said tubular sleeve has an axial dimension approximating that of the container body and neck portion for shrinkage around such major exterior surface areas.
Claim 6
Dependent Claim
22 words
The method in accordance with claim 2, wherein said tubular sleeve has a length slightly less than the glass bottle height dimension.
Claim 7
Dependent Claim
46 words
The method in accordance with claim 1, wherein said sleeve is initially heated annularly in a mid-point region to partially heat-shrink and adhere said sleeve to the container mid-body portion prior to heating remaining portions of said sleeve for complete heat-shrinkage around said container external surfaces.
Claim 8
Independent Claim
141 words
The method of labeling containers such as glass or plastic bottles, and the like, comprising the steps of providing a preformed tubular sleeve of preprinted heat-shrinkable organic thermoplastic thin film material, opening said sleeve into substantially fully open tubular arrangement, retaining the said container in an inverted vertical position by grasping the lowermost mouth portion of said container, transporting the said container and said sleeve simultaneously in vertically-aligned relation with said sleeve retained over said container during their simultaneous movement in co-axial alignment, telescoping said sleeve downwardly over the body and neck portions of said inverted container to surround its major exterior surface areas, said sleeve having a diameter slightly greater than said container diameter and a length slightly lesser than the container height dimension, and heat shrinking said sleeve snugly around said body and neck portions in essentially wrinkle-free condition.
Claim 9
Independent Claim
141 words
The method of labeling containers such as glass or plastic bottles, and the like, comprising the steps of providing a preformed tubular sleeve of preprinted heat-shrinkable organic thermoplastic thin film material, opening said sleeve into substantially fully open tubular arrangement, retaining the said container in an inverted vertical position by grasping the lowermost mouth portion of said container, transporting the said container and said sleeve simultaneously in vertically-aligned relation with said sleeve retained over said container during their simultaneous movement in co-axial alignment, telescoping said sleeve downwardly over the body and neck portions of said inverted container to surround its major exterior surface areas, said sleeve having a diameter slightly greater than said container diameter and a length slightly lesser than the container height dimension, and heat shrinking said sleeve snugly around said body and neck portions in essentially wrinkle-free condition.
Claim 10
Dependent Claim
32 words
The method in accordance with claim 7, wherein said container comprises a cylindrical glass bottle and said sleeve comprises a foamed oriented polyethylene material having its major orientation in a circumferential direction.
Claim 11
Dependent Claim
20 words
The method in accordance with claim 7, wherein said sleeve is provided in preformed flat-folded arrangement prior to said opening.
Claim 12
Independent Claim
120 words
The method of labeling a bottle having a cylindrical body portion and frusto-conical neck portion comprising the steps of providing a preformed, tubular sleeve of preprinted, heat-shrinkable, organic, thermoplastic, thin film material having a diameter slightly greater than the body portion of said bottle, opening said sleeve into open tubular arrangement, retaining the bottle by its neck portion in an inverted position, transporting the said bottle and sleeve in vertically aligned relation with said open sleeve retained over said bottle, telescoping said sleeve downwardly over said body and neck portions of said inverted bottle, and heating said sleeve to shrink it into snug essentially wrinkle-free engagement with the exterior surfaces of said body and neck portions of said plastic bottle.
Claim 13
Independent Claim
120 words
The method of labeling a bottle having a cylindrical body portion and frusto-conical neck portion comprising the steps of providing a preformed, tubular sleeve of preprinted, heat-shrinkable, organic, thermoplastic, thin film material having a diameter slightly greater than the body portion of said bottle, opening said sleeve into open tubular arrangement, retaining the bottle by its neck portion in an inverted position, transporting the said bottle and sleeve in vertically aligned relation with said open sleeve retained over said bottle, telescoping said sleeve downwardly over said body and neck portions of said inverted bottle, and heating said sleeve to shrink it into snug essentially wrinkle-free engagement with the exterior surfaces of said body and neck portions of said plastic bottle.
