• Refrigerated goods containers are usually enclosed on five sides containers in which refrigerated goods such as vegetables can be stored in a refrigerator. In most cases, they can be pulled out or removed from the interior of the refrigerator in order to fill them better or to remove refrigerated goods stored in them more easily.
• the refrigerated goods container and / or the storage area often have special arrangements with which the refrigerated goods container can be moved more easily on the storage area ,
• rollers are provided under a front or rear portion of a bottom of the refrigerated goods container, which run on a corresponding mating surface of the bearing surface.

• the guide rail has a tread arranged radially to the guide roller and an axially disposed to the guide roller guide profile.
• the guide profile is spaced from the guide roller and arranged to the tread.
• the guide rail can thus be designed for the exact spatial guidance of the guide roller without at the same time providing the running surface for the guide roller.
• optimized materials can be selected both for the guidance and for the running surface of the guide roller.
• Suitable materials of the guide profile and tread can be chosen so that on the one hand reduces the frictional resistance and thus a low-noise operation of the refrigerated goods on the tread are achieved and on the other hand high stress of the guide profile can be made possible without major wear.
• a lateral guidance of the guide roller through the profile is preferred over a guide at the bottom of the refrigerated goods container, as a guide of the guide roller can be achieved not only along the withdrawal direction of the refrigerated goods, but also in the radial direction of the guide roller up and down. Therefore, the guide profile in a preferred embodiment surrounds at least a portion of the guide roller.

Thus, it does not obstruct the extraction of the refrigerated goods container advantageously, since it preferably causes only a slight friction.
• the supporting roller advantageously maintains contact with the second U-leg of the guide rail and thus supports the refrigerated goods container against falling out of the bearing surface of the refrigerating appliance.

If the roller and the guide roller are preferably arranged opposite one another in the inserted state of the refrigerated goods container, then a run of the refrigerated goods container over the running surface can be provided, which is preferably predominantly limited only by slight rolling friction.
• a running groove for guiding the roller is provided, so that the roller is advantageously performed as well as the guide roller in the direction of the refrigerated goods and thus a lateral displacement of the refrigerated goods container can preferably be prevented.
• the materials in particular plastic materials, of guide, running and / or support roller and guide rail selected such that when passing a refrigerated goods a low friction noise.
• a corresponding combination of a refrigerated goods container for a refrigeration appliance and a storage area for storing the refrigerated goods container in a refrigeration appliance has the above-described guide arrangement.
• the guide roller on the refrigerated goods container and the guide rail are arranged on the bearing surface in an advantageous embodiment.
• the guide roller is arranged recessed on a bottom region of the refrigerated goods container.

• the geometry of the guide rails 26 and another small role, the support roller 40, in the rear of the refrigerated goods 14 prevent tilting of the refrigerated goods 14 in the extended state forward. If the refrigerated goods container 14 tilts, the rear roller of the refrigerated goods container 14 is held on the upper wall of the guide rail 26 and assumes the guiding or sliding function from this point in time.
• This combination of several roles facilitates the removal of the refrigerated goods container 14, the handling of the refrigerated goods container 14 and reduces dragging noises, which may also indicate a generation of abrasion.
