  Embodiments of the present invention will be described below with reference to the accompanying drawings.

As a reference form serving as a basis of the present invention, a variable height box shown by a blank in FIG. 1 includes a base sheet 1 and a cover sheet 2 made of cardboard.

  The width W of the base sheet 1 is determined in consideration of handling in the physical distribution process. Two first ruled lines a are put in the middle part of the base sheet 1 with a gap from both end edges, and the bottom plate 11 is formed between them. The interval between the two first ruled lines a is also determined in consideration of handling in the physical distribution process. The step direction of the cardboard is directed in a direction intersecting the first ruled line a.

  The cover sheet 2 is also provided with two first ruled lines a with a gap from both edges, and the top plate 21 is formed between the first ruled lines a. The interval between the two first ruled lines a is set to be slightly larger than the width W of the base sheet 1 in consideration of the thickness of the cardboard. The step direction of the cardboard is directed in a direction intersecting the first ruled line a.

  In addition, the cover sheet 2 is provided with a sticking portion 24 surrounded by a score line that is cut at the time of opening, near both ends and one edge of the top plate 21, and near the other edge. A tear band 25 made of a score line or cut tape is provided. The adhering portion 24 and the tear band 25 in the vicinity of the edge are arranged on the end side from the second ruled line b regardless of the position of the second ruled line b described later.

  The base sheet 1 and the cover sheet 2 are stored in a flat blank state, and are supplied to an assembling apparatus when packing various products.
