Abstract
Abstract A package accommodating a group of like flanged containers disposed in more than one row includes a top panel (16) and overlapping base panels (12,20) interconnected by spaced side walls (14,18) thereby providing a tubular structure in which the containers are received. The base panels include a keel (K) adapted to separate the containers in one row (R 1 ) from those in an adjacent row (R 2 ). One of the base panels is provided with locking elements (48) adapted to interlock with cooperating locking elements (46) provided by the other of the base panels thereby to maintain the package in its tubular form. Auxiliary cooperating locking elements are provided by the base panels and interlocked to minimize distortion of the keel, and portions of the top flanges (f) of the containers in one row (R 1 ) are overlapped with portions of top flanges of the containers in an adjacent row (R 2 ) and portions of the top panel are interposed between the overlapped portions of the container flanges.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
168 words
A package accommodating a group of like containers disposed in more than one row, the package including a top panel and overlapping base panels interconnected by spaced side walls thereby providing a tubular structure in which said containers are received, said base panels including a keel formed to separate the containers in one row from those in an adjacent row, one of said base panels being provided with locking means arranged to interlock with cooperating locking means provided by another of said base panels to maintain the package in its tubular form, and an auxiliary cooperating locking means being provided by said base panels and interlocked to minimize distortion of said keel, characterised in that said locking means is provided between said keel and one of said side walls of the package and said auxiliary locking means is arranged between said keel and the opposite side wall of the package whereby said base panels are locked in overlapped relationship at spaced locations on opposite sides of said keel.
Claim 2
Dependent Claim
168 words
A package accommodating a group of like containers disposed in more than one row, the package including a top panel and overlapping base panels interconnected by spaced side walls thereby providing a tubular structure in which said containers are received, said base panels including a keel formed to separate the containers in one row from those in an adjacent row, one of said base panels being provided with locking means arranged to interlock with cooperating locking means provided by another of said base panels to maintain the package in its tubular form, and an auxiliary cooperating locking means being provided by said base panels and interlocked to minimize distortion of said keel, characterised in that said locking means is provided between said keel and one of said side walls of the package and said auxiliary locking means is arranged between said keel and the opposite side wall of the package whereby said base panels are locked in overlapped relationship at spaced locations on opposite sides of said keel.
Claim 3
Dependent Claim
93 words
A package accommodating a group of like containers having outwardly projecting flanges at the tops thereof and being disposed in more than one row, the package including a top panel and base panel means interconnected by spaced side walls thereby providding a tubular structure in which said containers are received, characterized in that portions of the flanges of containers in one row are overlapped with portions of the flanges of containers in an adjacent row and in that portions of said top panel are interposed between said overlapped portions of said container flanges.
Claim 4
Dependent Claim
93 words
A package accommodating a group of like containers having outwardly projecting flanges at the tops thereof and being disposed in more than one row, the package including a top panel and base panel means interconnected by spaced side walls thereby providding a tubular structure in which said containers are received, characterized in that portions of the flanges of containers in one row are overlapped with portions of the flanges of containers in an adjacent row and in that portions of said top panel are interposed between said overlapped portions of said container flanges.
Claim 5
Dependent Claim
167 words
A package accommodating a group of like containers having outwardly projecting flanges at the tops thereof and being disposed in more than one row, the package including a top panel and overlapping base panels interconnected by spaced side walls therby providing a tubular structure in which said containers are received, said base panels including a keel formed to separate the containers in one row from those in an adjacent row, one of said base panels being provided with locking tabs arranged to interlock with cooperating locking apertures provided by another of said base panels to maintain the package in its tubular form, characterised in that auxiliary cooperating locking means are provided by said base panels and interlocked to minimise distortion of said keel and in that inwardly extending portions of the flanges of containers in one row are overlapped with portions of the flanges of containers in an adjacent row and in that portions of said top panel are interposed between the overlapped portions of said flanges.
Claim 6
Dependent Claim
