Abstract
Abstract There is disclosed a carrier for a plurality of articles or containers such as boxes, cans, bottles and the like, and a method of making the same, comprising providing a flattened tube of plastic material which is partially slit for defining successive sections which may be unfolded to form interconnected annular rings for insertion of the articles and which tube is provided with integral webs extending between the rings for presenting handle or gripping means for the carrier.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
79 words
A carrier for a plurality of articles such as containers and the like comprising a set including a pair of adjacently disposed annular sections of flexible material each having an upstanding wall having a height greater than its thickness and upper and lower margins, said annular sections having an area of closest proximity to each other, and elements extending between said annular sections at opposite sides of said area and providing handle means for facilitating handling of the carrier.
Claim 2
Dependent Claim
79 words
A carrier for a plurality of articles such as containers and the like comprising a set including a pair of adjacently disposed annular sections of flexible material each having an upstanding wall having a height greater than its thickness and upper and lower margins, said annular sections having an area of closest proximity to each other, and elements extending between said annular sections at opposite sides of said area and providing handle means for facilitating handling of the carrier.
Claim 3
Dependent Claim
38 words
A carrier as defined in claim 1 which includes a plurality of said sets of said annular sections, and flexible junction elements joining adjacent annular sections of adjacent sets to each other along segments of their adjacent margins.
Claim 4
Dependent Claim
59 words
A carrier as defined in claim 2 which includes at least three of said sets of annular sections, certain of said junction elements joining upper margins of sections of an intermediate set to sections of a first adjacent set and other said junction elements joining lower margins of sections of said intermediate set to sections of another adjacent set.
Claim 5
Dependent Claim
19 words
A carrier as defined in claim 1 wherein said set of annular sections includes at least three annular sections.
Claim 6
Dependent Claim
21 words
A carrier as defined in claim 2 wherein each of said sets of said annular sections consists of two annular sections.
Claim 7
Dependent Claim
23 words
A carrier as defined in claim 2, wherein each of said sets of annular sections comprises two pairs of adjacently disposed annular sections.
Claim 8
Independent Claim
129 words
A method of forming a carrier having a plurality of thin-walled upstanding adjacent annular sections presenting free upper and lower margins with junction elements joining adjacent segments of margins of adjacent annular sections and strap-like elements between adjacent annular sections comprising providing a tube structure of thin flexible material including a pair of side-by-side tubes having a longitudinal area of closest proximity to each other and web elements extending between said tubes at opposite sides of said area, substantially flattening said tubes together with said area and said web elements therebetween and thereby providing a substantially flattened tube structure presenting opposite margins, and alternately transversely slitting the tube structure from said opposite margins partially across the tube structure and along generally parallel lines spaced axially of the tube structure.
Claim 9
Independent Claim
129 words
A method of forming a carrier having a plurality of thin-walled upstanding adjacent annular sections presenting free upper and lower margins with junction elements joining adjacent segments of margins of adjacent annular sections and strap-like elements between adjacent annular sections comprising providing a tube structure of thin flexible material including a pair of side-by-side tubes having a longitudinal area of closest proximity to each other and web elements extending between said tubes at opposite sides of said area, substantially flattening said tubes together with said area and said web elements therebetween and thereby providing a substantially flattened tube structure presenting opposite margins, and alternately transversely slitting the tube structure from said opposite margins partially across the tube structure and along generally parallel lines spaced axially of the tube structure.
Claim 10
Dependent Claim
91 words
A package comprising a plurality of justaposed articles such as containers and a carrier retaining said articles in the package, said carrier comprising a set including at least two adjacently disposed annular thin-walled sections of flexible, stretchable materal each having an upstanding wall having a height greater than its thickness and upper and lower free margins, said annular sections having an area of closest proximity to each other, and elements extending between said annular sections at opposite sides of said area and providing handle means for facilitating handling of the carrier.
Claim 11
Dependent Claim
91 words
A package comprising a plurality of justaposed articles such as containers and a carrier retaining said articles in the package, said carrier comprising a set including at least two adjacently disposed annular thin-walled sections of flexible, stretchable materal each having an upstanding wall having a height greater than its thickness and upper and lower free margins, said annular sections having an area of closest proximity to each other, and elements extending between said annular sections at opposite sides of said area and providing handle means for facilitating handling of the carrier.
Claim 12
Dependent Claim
39 words
A package as defined in claim 8, wherein said carrier includes a plurality of said sets of annular sections, and flexible junction elements joining adjacent annular sections of adjacent sets to each other along segments of their adjacent margins.
