Abstract

The invention relates to a box comprising a base (2) provided with a stationary outer wall area (18) which extends upwardly from the base in the vertical direction (8) and an outer wall (6b) comprising a shaft (50) which is arranged in the base area of the outer wall (6b). A guide opening (54) is formed in the stationary outer wall area (18) in which the shaft (50) is arranged and which comprises a lateral opening section (54b) which extends inwardly essentially in the lateral direction (12) from an outer side of the stationary outer wall area (18), displaceable in the shaft (50). Said stationary outer wall area (18) comprises a bearing surface (76) which is arranged therein. A cam (52) is arranged in the base area of the stationary outer wall area (6b) and comprises a cam contour which is designed in such a manner that said cam contour, when assembling the outer wall (6b), rests upon the bearing surface (76), such that when a critical angle (68) is exceeded, the shaft (50) in displaced inwardly in the lateral opening section (54b). After exceeding the critical angle (68), a lower side (66) of the outer wall (6b) is pressed against an inner edge area (90) of the stationary outer wall area (18) by means of first contact pressure due to the actuation of the shaft (50) or the cam (52), said first contact pressure being greater than a second contact pressure, with which the lower side (66) of the outer wall (6b) is pressed against an upper side of the stationary outer wall area (18) in the vertical position due to the actuation of the shaft (50) or the cam (52).
