Abstract
Abstract A container having a hollow tubular section of polygonol cross section with two end closure members each having a flat center section of the same shape and approximate size as the cross section of the tube and a plurality of tabs projecting from the periphery of the central section and interlocking with the end portions of the tube. In a method of assembling the container, some of the flaps of one end closure are inserted between portions of the contents prior to enclosure of the contents by the tube.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
A container having, in combination, a hollow tube of polygonal cross section with an even number of sides, top and bottom end members each having a flat center portion of the same shape and approximate size as said cross section of said tube and flaps secured to and extending outwardly from the side edges of each of said top and bottom members, alternate ones of said flaps of each of said end members being folded laterally of said center section and lying along the inner surfaces of corresponding sides of said tube and the intervening flaps being folded laterally of the center portion and lying along the outer surfaces of said tube sides when the ends are assembled with said tube, at least two of said intervening flaps on opposite sides of said top member being folded reversely upon themselves prior To being placed against said tube sides to provide handholds for said container, and means to secure said intervening flaps against said outer surfaces of said tube sides.
Claim 2
Dependent Claim
169 words
A container having, in combination, a hollow tube of polygonal cross section with an even number of sides, top and bottom end members each having a flat center portion of the same shape and approximate size as said cross section of said tube and flaps secured to and extending outwardly from the side edges of each of said top and bottom members, alternate ones of said flaps of each of said end members being folded laterally of said center section and lying along the inner surfaces of corresponding sides of said tube and the intervening flaps being folded laterally of the center portion and lying along the outer surfaces of said tube sides when the ends are assembled with said tube, at least two of said intervening flaps on opposite sides of said top member being folded reversely upon themselves prior To being placed against said tube sides to provide handholds for said container, and means to secure said intervening flaps against said outer surfaces of said tube sides.
Claim 3
Dependent Claim
198 words
A container having, in combination, a hollow tube of polygonal cross section with an even number of sides, said hollow tube being made from a generally flat sheet having parallel top and bottom straight edge surfaces, top and bottom end members each having a flat center portion of the same shape and approximate size as said cross section of said tube and having flaps secured to and extending outwardly from the side surfaces of each of said top and bottom members, alternate ones of said flaps of each of said end members being folded laterally of said center portion and lying along the inner surfaces of corresponding sides of said tube and the intervening flaps being folded laterally of the center portion and lying along and against the outer surfaces of said tube sides when the ends are assembled with said tube, said alternate ones of said flaps being longer than said intervening flaps to assist in assembly of said container, and means releasably securing said intervening flaps against said outer surfaces of said tube sides to permit disassembly of said top and bottom end members and collapse of said hollow tube and end members to flat conditions.
Claim 4
Dependent Claim
198 words
A container having, in combination, a hollow tube of polygonal cross section with an even number of sides, said hollow tube being made from a generally flat sheet having parallel top and bottom straight edge surfaces, top and bottom end members each having a flat center portion of the same shape and approximate size as said cross section of said tube and having flaps secured to and extending outwardly from the side surfaces of each of said top and bottom members, alternate ones of said flaps of each of said end members being folded laterally of said center portion and lying along the inner surfaces of corresponding sides of said tube and the intervening flaps being folded laterally of the center portion and lying along and against the outer surfaces of said tube sides when the ends are assembled with said tube, said alternate ones of said flaps being longer than said intervening flaps to assist in assembly of said container, and means releasably securing said intervening flaps against said outer surfaces of said tube sides to permit disassembly of said top and bottom end members and collapse of said hollow tube and end members to flat conditions.
Claim 5
Dependent Claim
193 words
A container having, in combination, a hollow tube of polygonal cross section with an even number of sides, said hollow tube being made from a generally flat sheet having parallel top and bottom straight edge surfaces, top and bottom end members each having a flat center portion of the same shape and approximate size as said cross section of said tube and having flaps secured to and extending outwardly from the side surfaces of each of said top and bottom members, alternate ones of said flaps of each of said end members being folded laterally of said center portion and lying along the inner surfaces of corresponding sides of said tube and the intervening flaps being folded laterally of the center portion and lying along and against the outer surfaces of said tube sides when the ends are assembled with said tube, said alternate ones of said flaps being pointed to facilitate assembly of said container, and means releasably securing said intervening flaps against said outer surfaces of said tube sides to permit disassembly of said top and bottom end members and collapse of said hollow tube and end members to flat conditions.
Claim 6
Dependent Claim
193 words
A container having, in combination, a hollow tube of polygonal cross section with an even number of sides, said hollow tube being made from a generally flat sheet having parallel top and bottom straight edge surfaces, top and bottom end members each having a flat center portion of the same shape and approximate size as said cross section of said tube and having flaps secured to and extending outwardly from the side surfaces of each of said top and bottom members, alternate ones of said flaps of each of said end members being folded laterally of said center portion and lying along the inner surfaces of corresponding sides of said tube and the intervening flaps being folded laterally of the center portion and lying along and against the outer surfaces of said tube sides when the ends are assembled with said tube, said alternate ones of said flaps being pointed to facilitate assembly of said container, and means releasably securing said intervening flaps against said outer surfaces of said tube sides to permit disassembly of said top and bottom end members and collapse of said hollow tube and end members to flat conditions.
Claim 7
Dependent Claim
15 words
A container as set forth in claim 1 wherein said polygonol cross section is octagonal.
Claim 8
Dependent Claim
48 words
A container as set forth in claim 1 wherein a portion of said alternate ones of said flaps on said bottom member are further folded inwardly parallel to said flat center portion over a portion of the contents of said container to facilitate the assembly of said container.
Claim 9
Dependent Claim
57 words
A container as set forth in claim 1 further comprising at least one strap extending around said top and bottom members and along two sides of said tube, said strap overlying at said intervening flaps on each of said top and bottom members to cause said flaps to lie along the outer surfaces of said tube sides.
