Abstract
The packaging case comprises, when assembled, a back part (aback hanging board), a bottom part (a bottom cover), a front part (a front cover, a front hanging board), the boards and covers being formed continuously in this order and bordered by fold lines, and a side part (a side cover, a glue margin) continuously extending from each side edge of the front cover except the neighborhood of the front hanging board and bordered by fold lines. A window is formed in the front cover, and a hook hole is respectively punched in the front and the back hanging boards to make a single matching hook hole. In one side edge of the back hanging board, a U-shaped perforated tear portion is provided for tearing off a part of the side edge glued to a corresponding glue margin. By gluing the front hanging board and the glue margins to the back hanging board, a plurality of cylindrical articles are enclosed by the front cover, bottom cover, back hanging board and side covers, with both ends of each article facing the side covers, and the cylindrical surface thereof being partially exposed through the window.
