Abstract: The present invention relates to a module system comprising a case and a number of boxes. Each box is defined by a cross-sectional area of an opening of the respective box. The case has a case lid and a case bottom part. The case lid and the case bottom part forms an interior space within the case, and the boxes are to be stored in the interior space of the case. The cross-sectional area of one box is approximately a multiple (n) of any cross-sectional area of any of the number of boxes that are to be stored in the interior space of the case. The case lid is provided with sealing means that sealingly fits over and in abutment with an upper surface of at least one box, with the case in closed position, when the boxes are stored in the interior space of the case.
