Fig. 1 shows the front view of a drawer container 2 with attached container rails 1, 1 'and Fig. 1a shows the circular area of the Fig. 1 in an enlarged view. The container rails 1, 1 'are used for fastening the drawer container 2 on, for example, in a furniture body 3 (not shown here) Drawer pull-5, on which the drawer container 2 for pulling out of the furniture body 3 and for driving into the furniture body 3 in the rail longitudinal direction L mobile is stored. The drawer pull-out guides 5 typically each comprise at least one carcass-resistant carcass rail 16 and a rail 4 displaceable in the rail longitudinal direction L (see FIG Fig. 4 ). Between the carcass rail 16 and drawer rail 4, a middle rail 17 may additionally be arranged, by means of which a full extension of the drawer container 2 from the furniture carcass 3 can be made possible.

The drawer bottom 11 of the drawer container 2 has on its underside in the region of the outer edges recesses 12, wherein the recesses 12 are formed open to the side edge of the drawer bottom 11, so that the container rails 1, 1 'in the recesses 12 of the drawer bottom 11 are used , The recesses 12 extend in this example substantially over the entire length of the drawer bottom 11. The container rails 1, 1 'have U-shaped sections 6, to which each horizontal support webs 10 follow. The U-shaped sections 6 each comprise a leg 9, which protrudes substantially at right angles from the respective horizontal support web 10. An attachment of the container rails 1, 1 'on the underside of the drawer bottom 11, for example, by suitable fastening means, such as screw, on the horizontal support webs 10 and / or on the legs 9 of the container rails 1, 1' done.

In the example shown, the U-shaped portion 6 of the container rail 1 has a horizontal web 8, wherein the horizontal web 8 a running in the rail longitudinal direction L stop 7 (see Fig. 2 ) has for the drawer rail 4 a drawer extension guide 5. The stop 7 is arranged horizontally spaced from the leg 9, whereby the remaining clear width B of the U-shaped portion 6 is reduced accordingly.

In addition, in this example, the leg 9 has a second stop 7a (see Fig. 2 ), wherein the remaining clear width B 'between the first stop 7 on the horizontal web 8 and the second stop 7a on the leg 9 is greater than or equal to the width b of the drawer rail 4. In this case, the remaining clear width B 'is only slightly larger than the width b of the drawer rail 4, so that the container rail 1 can be placed on the drawer rail 4 with very little play and thus can be guided very well. Preferably, it may be provided that the clearance between the vertical legs of the drawer rail 4 and the respective stop 7, 7a is only 0.2 mm to 0.8 mm, preferably only 0.1 mm to 0.4 mm.

This results in the hanging of the drawer container 2 with attached container rails 1, 1 'on the drawer rails 4 Schubladenausziehführungen 5 a good guide with little play, so in particular when inserting the drawer container 2 for connecting the container rails 1, 1' with the drawer rails 4, for example, arranged in the U-shaped sections 6 couplings 14 (see Fig. 3 ), a tilting of the drawer container 2 can be avoided.

The stops 7, 7a of the container rail 1 thus lead on the one hand to easier insertion of the drawer container 2 on the drawer extension guides 5. On the other hand, thereby the connection of the drawer rails 4 can be simplified with the couplings 14, as by the stops 7, 7a, the container rails 1, 1 'and thus the clutches 14 can be prepositioned in the correct position relative to the drawer rails 4 in order to connect them in a simple manner to the drawer rails 4 with corresponding devices. Third, by avoiding tilting of the drawer container 2 during assembly of the drawer container 2 to the Loading rails 4 damage to the drawer side walls 15 can be avoided.
