Object e.g. portable computer, or object part blocking block, has wall with internal side conformed such that thickness of wall between internal and external sides is varied, where internal side is curved at convexity towards cell interior

摘要

The block has a wall (21) with an internal side (41) delimiting a side of a cell (3) and curved at convexity towards the cell interior. The side (41) is connected at its ends to respective internal sides (42, 44) of respective walls (22, 24) by deformability notches (5). The side (41) is conformed such that the thickness of the wall (21) between its internal and external sides is varied.
