Abstract
Pack made from board for free-flowing products such as detergent, with two side panels, a front panel, a back panel, a base and a closure flap which is hinged to the back panel and under which further flaps hinged to the other panels are located, where the flap hinged to the front panel extends across the whole cross-section of the pack and has a tab hinged to it that rests against the inside of the closure flap. The flap (24) hinged to the front panel (3) has parallel score lines (27, 28) provided at least to some extent in duplicate and located a short distance from the top edges of the two side panels (4, 5) which also extend across the hinged tab (26) and act as tear lines. Sections (19, 20, 21) that overlap the side panels (4, 5) and the front panel (3) to at least a small extent are provided on the closure flap (17), the section (21) overlapping the front panel (3) being provided with a tab (32), in the area of which this section is glued to the front panel for subsequent separation (31).
