• the structuring of the supporting feet 57a and the front engaging recesses 54a is such that there is no locking in the stacking direction 2, so that the front portion 53 of the upper container 1 can be raised at any time when the coupling means 26 is in the release position.

• Their special feature is that they act as Hintergreif beaumaschineer the second engagement structure 49, which are able to engage behind the locking engagement formed for a rear engagement recess 54b inwardly transversely to the stacking direction 2, so that a relative movement in the stacking direction 2 preventing locking engagement is present.
• the rear engagement recess 54b is also referred to as a locking engagement recess. If each locking stand 57b has its own engagement recess 54, it is also designed as a locking engagement recess.
• the otherwise upwardly open locking engagement recess 54b has at least at its the rear end surface 16b adjacent edge region in the depth direction 25 forwardly projecting, preferably rib-shaped Schugreifvor- jump 58, which results in that the locking engagement recess 54b has an opening cross-section , which is less than the base area of the recess bottom.
• Each locking stand 57b has on the rear end face 16b facing rear over a suitably wedge-shaped profiled rear gripping portion 62, so that in the transition region to the outer base 56 of the bottom wall 22 results in a gap having a complementary to the Schumreifvorsprung 58 cross section ( FIG. 11).
• the dimensions of the opening of the lock engagement recess 54b are larger in the depth direction 25 than those of each lock stand 57b.
• the upper container 1 In order to place an upper container 1 on a lower container 1, the upper container 1 according to FIG. 10 is tilted in an inclined position and, with the rear portion 52 inclined downwards, protruded onto the upper side 19 of the lower container 1. With the locking feet 57b immersed in the locking engagement recess 54b. At the same time or subsequently, the upper container 1 is pushed or pushed backwards in accordance with the arrow 63, so that the rear grip sections 62 engage in interlocking engagement with the at least one rear engagement projection 58. The area in which this locking engagement takes place may be referred to as the locking area 64.
• the rear portion 52 of the upper case 1 is secured to a vertical lift by the locking engagement between the lock upstands 57b and the lock engagement recess 54b.
• the corresponding vertical securing of the front region 53 takes place by turning the coupling means 26 into the coupling position.
• the insertion of the supporting feet 57a into the front engaging recesses 54a may be facilitated by forming the side wall of the front engaging recesses 54a at least partially as an inclined sliding surface 67.
• the front engagement recesses 54a thus have a larger cross-section in the region of their opening than on the floor surface. che, wherein this cross-sectional difference is bridged by the inclined sliding surfaces 67. There is thus an automatic centering when placing the upper container instead.

• This locking bar 68 also forms an engagement component of the second engagement structure 49, which acts in addition to the locking feet 57b and which increases the length of the locking contact so that a greater load-bearing capacity is achieved.
• the measured in the stacking direction 2 height of the locking bar 68 is suitably lower than that of the locking feet 57 b, so that the latter project beyond the locking bar 68 downwards.

In addition, it is advantageously designed so that it can adopt either an apparent from the drawing, pivoted to the top 19 zoom in non-use position or indicated in Figure 6, pivoted upward and thus upwardly over the top 19 protruding use position. It is preferably a bow-shaped carrying handle 72 with a U-shaped design.
