Claim:
1. Assembly of at least two stackable transport trunks, each trunk having a body with a generally parallelepiped shape, comprising a bottom and four sidewalls connected to the bottom and being closed by a removable lid, wherein each trunk comprises nesting means on its four sidewalls comprising at least two mutually parallel interlocking ribs on each sidewall, the nesting means of one said trunk engaging with the nesting means of a sidewall of another said trunk on which it is stacked, wherein the nesting means of respective said trunks are adapted, when they engage, to define a sliding link having a sliding direction parallel to the sidewalls having the nesting means and to the bottoms of the trunks and for guiding the translation of the trunks on each other, the corresponding sidewalls being adapted for enabling the engagement of the nesting means and enabling said translation, wherein the opposite internal edges of the at least two mutually parallel interlocking ribs on each sidewall are separated by an internal gap, whilst the external edges facing towards the outside opposite the internal edges are separated by an external gap, wherein for each pair of opposite sidewalls of a respective said trunk, the external gap in the interlocking ribs on one of the opposite sidewalls is less than or equal to the internal gap in the interlocking ribs on the other of the opposite sidewalls, wherein respective adjacent sidewalls of a respective said trunk each have approximately equal internal and external gaps.
