摘要

The packaging box comprises a body (11) and a cover (12) which can pivot around an edge (13). The body has a front face (14) and the cover has a flap (16) which is parallel to the body front face when closed. A tab (19a) on the lower edge of the flap penetrates a slot (19) in the front face to hold the cover closed. The roller is formed from a succession of sections separated from each other by a pre-cut line. The upper edge of the front face has a projection (18) near the cover which engages the pre-cut line of the sheet roll during its unwinding from the roller.
