Abstract

Abstract A unitized package of a plurality of generally cylindrical containers, such as cans or bottles, is disclosed. The package is sufficiently rigid to maintain a stable configuration upon handling even when the package is constituted by a relatively large number of containers. The unitized package comprises several independent, integral container cells of equal size that are held contiguous to one another by a resilient film ribbon under tension. The resilient film ribbon is in contact with the packaged containers about the periphery of the package along a major portion of the container cylindrical body portion length dimension. A particularly well suited film ribbon material for the foregoing purposes is oriented polypropylene film about 3 to 5 mils thick.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 192 words
A unitized package constituted by a plurality of substantially uniform containers arranged in rows and columns, each container having a cylindrical body portion, and comprising: at least two contiguous but separate, integral container cells of equal size; and a resilient but relatively inelastic film ribbon of oriented polypropylene under tension, circumscribing said contiguous container cells; each said container cell including a separate container connecting means, and at least two containers aligned with one another and individually gripped by the connecting means so that movement of the gripped containers relative to one another is restricted; and said resilient film ribbon being in contact with containers about the periphery of the package along a approximately 50% of the length of the cylindrical body portion length dimension and being under a tension of at least about one pound force per pound of total package weight but less than a tension that impairs the configurational integrity of individual containers in the package, said tension being distributed substantially uniformly across the width of the film ribbon, said film ribbon including a fusion welded seam substantially across the width of the ribbon at overlapping extremities of the ribbon.
Claim 2
Dependent Claim 192 words
A unitized package constituted by a plurality of substantially uniform containers arranged in rows and columns, each container having a cylindrical body portion, and comprising: at least two contiguous but separate, integral container cells of equal size; and a resilient but relatively inelastic film ribbon of oriented polypropylene under tension, circumscribing said contiguous container cells; each said container cell including a separate container connecting means, and at least two containers aligned with one another and individually gripped by the connecting means so that movement of the gripped containers relative to one another is restricted; and said resilient film ribbon being in contact with containers about the periphery of the package along a approximately 50% of the length of the cylindrical body portion length dimension and being under a tension of at least about one pound force per pound of total package weight but less than a tension that impairs the configurational integrity of individual containers in the package, said tension being distributed substantially uniformly across the width of the film ribbon, said film ribbon including a fusion welded seam substantially across the width of the ribbon at overlapping extremities of the ribbon.
Claim 3
Dependent Claim 14 words
The unitized package in accordance with claim 1 wherein the containers are cylindrical cans.
Claim 4
Dependent Claim 22 words
The unitized package in accordance with claim 1 wherein said container connecting means is a band circumscribing the containers in the cell.
Claim 5
Dependent Claim 18 words
The unitized package in accordance with claim 1 wherein said container connecting means is an apertured plastic sheet.
Claim 6
Dependent Claim 42 words
The unitized package in accordance with claim 1 wherein a pair of resilient film ribbons circumscribe the contiguous container cells and together are in contact with substantially the entire cylindrical body portion length dimension of containers about the periphery of the package.
Claim 7
Dependent Claim 47 words
The unitized package in accordance with claim 1 wherein four container cells are present in each package, six containers are present in each cell, and the cells are situated in the package with respect to one another so that each cell forms a quadrant of the package.
Claim 8
Dependent Claim 18 words
The unitized package in accordance with claim 1 wherein the fusion weld seam is between overlapping ribbon portions.
Claim 9
Dependent Claim 34 words
The unitized package in accordance with claim 1 wherein the fusion weld seam is between overlapping ribbon portions and a tab means unitary with the film ribbon is situated adjacent to the weld seam.
Claim 10
Dependent Claim 214 words
A unitized package constituted by a plurality of substantially uniform containers arranged in rows and columns, each container having a cylindrical body portion, and comprising: at least two contiguous but separate, integral container cells of equal size; and a resilient but relatively inelastic film ribbon of oriented polypropyene under tension, circumscribing said contiguous container cells; each said container cell including a separate container connecting means, and at least two containers aligned with one another and individually gripped by the connecting means so that movement of the gripped containers relative to one another is restricted; and said resilient film ribbon being in contact with containers about the periphery of the package along a major portion of the cylindrical body portion length dimension and being under a tension of at least about one pound force per pound of total package weight but less than a tension that impairs the configurational integrity of individual containers in the package, said tension being distributed substantially uniformly across the width of the film ribbon, each container cell further being connected by a continuous resilient elastic band circumscribing the outer periphery of each cell, said film ribbon under tension being juxtaposed over a portion of the width of the bands that are exposed to the outer periphery of the unitized package.
Claim 11
Dependent Claim 214 words
A unitized package constituted by a plurality of substantially uniform containers arranged in rows and columns, each container having a cylindrical body portion, and comprising: at least two contiguous but separate, integral container cells of equal size; and a resilient but relatively inelastic film ribbon of oriented polypropyene under tension, circumscribing said contiguous container cells; each said container cell including a separate container connecting means, and at least two containers aligned with one another and individually gripped by the connecting means so that movement of the gripped containers relative to one another is restricted; and said resilient film ribbon being in contact with containers about the periphery of the package along a major portion of the cylindrical body portion length dimension and being under a tension of at least about one pound force per pound of total package weight but less than a tension that impairs the configurational integrity of individual containers in the package, said tension being distributed substantially uniformly across the width of the film ribbon, each container cell further being connected by a continuous resilient elastic band circumscribing the outer periphery of each cell, said film ribbon under tension being juxtaposed over a portion of the width of the bands that are exposed to the outer periphery of the unitized package.
Claim 12
Dependent Claim 33 words
The unitized package of claim 9 wherein the contiguous but separate container cells include 12 containers each subgrouped into arrays of 6 containers which are individually gripped by the separate container connecting means.
