Product display unit according to claim 1, wherein the retaining element is part of the first upper guide carriage. 3. Product display unit according to claim 1, further comprising a first movement stop connected to the case and disposed so as to block horizontal displacement of the first upper guide carriage past the first movement stop along the upper guide rail. 4. Product display unit according to claim 3, further comprising a second movement stop, wherein the first movement stop is disposed in the area of the first upper guide rail and the second movement stop is disposed in the area of the first lower guide rail. 5. Product display unit according to claim 1, wherein the plurality of doors includes, in a front view, a middle door, which is mounted both in a pivoting and horizontally displaceable manner; a left end-side door disposed to the left of the middle door; a right end-side door disposed to the right of the middle door; wherein when assuming the closed position the middle door is not horizontally displaceable. 6. Product display unit according to claim 1, further comprising: a lighting device;wherein the first lower guide carriage and the first upper guide carriage are paired together such that the first upper guide carriage remains disposed vertically directly above the first lower guide carriage during displacement of the paired first lower guide carriage in the horizontal direction along the lower guide rail, andwherein the lighting device extends between the paired first lower and upper guide carriages. 7. Product display unit according to claim 6, wherein the lighting device is fastened to at least one of the paired first lower and upper guide carriages. 8. Product display unit according to claim 6, wherein a first one of the plurality of doors is connected to the paired first lower guide carriage and the first upper guide carriage and the lighting device is fastened to the first one of the plurality of doors. 9. Product display unit according to claim 6, further comprising a strut carried by the paired first lower and upper guide carriages, and wherein the lighting device is fastened to the strut. 10. Product display unit according to claim 1, wherein a first one of the plurality of doors is carried between the first upper guide carriage and the first lower guide carriage so as to be displaceable in the horizontal direction. 11. Product display unit according to claim 10, wherein the first upper guide carriage is connected to a first one of the plurality of doors, wherein the first upper guide carriage is connected to a second one of the plurality of doors, and wherein the first one of the plurality of doors is disposed adjacent the second one of the plurality of doors. 12. Product display unit according to claim 10, wherein the retaining element includes a spring element that exerts a retaining force, which is at least partly responsible for effecting a fixing of the first one of the plurality of doors mounted in a displaceable manner in its respective operating position. 13. Product display unit according to claim 12, wherein the retaining element is formed in such a manner that only the retaining force generated by the spring element must be overcome in order to effect the displacement of the first one of the plurality of doors from the operating position into the filling position. 14. Product display unit according to claim 10, wherein the first detent includes a recess configured to receive therein the retaining element so as to fix the first one of the plurality of doors in its operating position when the retaining element engages in the recess. 15. Product display unit according to claim 14, wherein the recess is defined in the case. 16. Product display unit according to claim 14, wherein the recess is a part of one of the first upper guide carriage and the first lower guide carriage, and the retaining element is a part of the case. 17. Product display unit according to claim 10, further comprising a pair of guide ropes connecting the first upper guide carriage with the first lower guide carriage. 18. Product display unit according to claim 17, further comprising: a first carrier rigidly connected to the case;a second carrier rigidly connected to the case;wherein the pair of guide ropes includes a first guide rope having a first end and a second end opposite the first end, the first end of the first guide rope being fixed to the first carrier and the second end of the first guide rope being fixed to the second carrier; andwherein the pair of guide ropes includes a second guide rope having a first end and a second end opposite the first end, the first end of the second guide rope being fixed to the first carrier and the second end of the second guide rope being fixed to the second carrier. 19. Product display unit according to claim 10, wherein the first one of the plurality of doors is mounted in such a manner that the first one of the plurality of doors is displaceable in the vertical direction with respect to the upper guide rail during relative horizontal displacement of the first one of the plurality of doors relative to the upper guide rail. 20.
