Because the body B and the cover L are assembled by folding one blank each, it is easy to produce them, and also because the surface is totally flat, they have superior printing characteristics. Furthermore, by providing the peripheral wall 9 of the cover L with a cut off piece 6 surrounded by the bottom edge and a cut off line 5, and by adhering this cut off piece 6 to the outside face of the peripheral wall 9 for sealing, when the cover is opened, the cut piece 6 is cut off from the cover L leaving the trace of it being opened.</p> |
