Container, blank, mandrel and method of forming the container
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).
Abstract(Chinese):

包括一排身体面板（P1-P4）的空白（2）和基本上平行于所述一排身体面板（P1-P4）延伸的一排端部封闭面板（P6-P9），其中每个端部闭合面板 P6-P9）具有边缘（E1-E4），并且其中第二（P7）和第四（P9）端盖板中的每一个具有斜线（S1，S11，S2，S12），其将其面板分成 邻近相应的边缘（E2，E4）的相应的第二或第四主体面板（P2，P4）和两个端部子组件（P7b，P7c，P9b，P9c）的中央子面板（P7a，P9a） 子板（P7b，P7c，P9b，P9c）从其对应的边缘（E2，E4）突出。 还描述了由片材坯料形成的容器和形成容器的方法。 该方法包括使用包括轴承表面（102）和基本上与所述支承表面（102）齐平的桥接表面部分（112）的心轴帽，并且在凹槽表面部分（104）之间在所述桥接件的相应相对侧处延伸 表面部分（112）。
