Abstract:
A sheet material blank from which a packaging container is to be made, comprising:a row of body panels comprised of first, second, third and fourth body panels, said row having a longitudinal center line extending in a direction, anda row of substantially rectangular, end closure panels extending substantially parallelly to said row of body panels and comprised of first, second, third and fourth end closure panels whereof each of the first and third end closure panels has first and second oblique lines of weakness which divide its panel into a central sub-panel of substantially isosceles triangular form and two end sub-panels of substantially triangular form,each of said first and third end closure panels including a central lug projecting outwardly away from said center line with respect to its panel and thereby bounding respective recesses in the outermost edge zone of its panel,the second end closure panel including a central lug projecting outwardly away from said center line with respect to its panel,the lugs of the first, second and third end closure panels projecting away from said center line to substantially the same extent as each other, andthe fourth end closure panel projecting from said center line to at least the same extent as do said lugs and there having an edge zone which is furthest from said longitudinal center line,wherein said central lug of said second end closure panel bounds respective recesses in the outermost edge zone of its panel, with those recesses being bounded also by respective edges of said second end closure panel which extend in substantially said direction,and wherein said lugs of the first, second and third end closure panels and the edge zone of said fourth end closure panel which is furthest from said longitudinal center line are so dimensioned that lugs of first, second and third end closure panels and edge zones of fourth end closure panels furthest from a longitudinal center line of rows of body panels of a first row of blanks identical to said blank are able to interdigitate with corresponding lugs and corresponding edge zones of a second row of blanks each identical to said blank.
