A container formed from a blank comprising a base 2, a flap sequence of two indexing wall flaps 3 extending from each of two opposed sides of the base 2, the first indexing wall flap 4 of each flap sequence being connected to the base 2 at a first fold line 6, the second indexing wall 5 of each flap sequence being connected to its associated first indexing wall flap by a second fold line 7 parallel to its the first fold line 6, where the container has the second indexing wall flap 5 of each flap sequence 3 inward of its associated first indexing wall flap 4, a non-indexing wall flap 8 extending from each of the other two sides of the base 2. Each of the non-indexing wall flaps 8 includes a pair of locking apertures 9. Each indexing wall flap sequence 3 has at each end a first extension flap beyond a third fold line 11 extending substantially normal to the second fold line 7, and a second extension flap extending from the first extension flap beyond a fourth fold line extending normal to the second and third fold lines. One of the first extension flap or the second extension flap includes a locking tab 29. At least a portion of the non-indexing wall flap is sandwiched between the first and second extension flaps, and the locking tab 29 passed through the locking aperture 9. Above a transition between each associated first and second indexing wall flap of an indexing wall flap sequence there is defined at least one indexing projection. The projection is indexable by an identical container having a cut or aperture in its base 2 for that purpose. Each fourth fold line includes at least one cut portion defining a locating aperture. The non indexing wall includes on an upper edge, upwardly projecting locating projections extending into or through a respective said locating aperture. |
