Abstract
A blank (2) comprising a row of body panels (P1-P4), and a row of end closure panels (P6-P9) extending substantially parallelly to the row of body panels (P1-P4), whereof each end closure panel (P6-P9) has an edge (E1-E4), and whereof each of the second (P7) and fourth (P9) end closure panels has oblique lines of weakness (S1, S11, S2, S12) which divide its panel into a central sub-panel (P7a, P9a) adjacent the corresponding second or fourth body panel (P2, P4) and two end sub-panels (P7b, P7c, P9b, P9c) adjacent the corresponding edges (E2, E4), wherein the end sub-panels (P7b, P7c, P9b, P9c) bulge away from its corresponding edge (E2, E4). A container formed from the sheet material blank and a method of forming the container is also described. The method involves the use of a mandrel cap including a bearing surface (102) and a bridging surface portion (112) substantially flush with said bearing surface (102), and extending between recessed surface portions (104) at respective opposite sides of said bridging surface portion (112).
