Patent ID: 8875924

Claim:
A foldable box comprising a floor and two longitudinal side and transverse side exterior walls each lying opposite in pairs and foldable with respect to the floor, comprising: each of the longitudinal side exterior walls comprises, at least at a transverse side end, a protrusion extending in the direction of the transverse side exterior walls in the upfolded state, the protrusion limiting the foldability of the transverse side exterior walls to the outside; and each of the transverse side exterior walls comprises a spring-pretensioned locking mechanism arranged at the outside of the transverse side exterior wall, which comprises in the upfolded state a snap-in element movable in a first direction perpendicular to the surface of the floor which may be latched with the protrusion of the longitudinal side exterior wall, wherein the protrusion and/or the snap-in element comprise contact surfaces which are inclined with respect to the first direction in the upfolded state such that the locking mechanism, when exceeding a predetermined force directed inwards acting upon the transverse side exterior wall opens against its spring-pretensioning.
