Abstract (en)
[origin: EP0158597A2] In this blank, there are two parallel perforated lines of weakness (65, 66) in the region of the side wall (20) and of the adjacent closure edge (24), extending as far as the outside edge. The external cover (34) possesses lines of weakness (55, 56) situated exactly over these lines of weakness. The push-in tab (51) thus formed in the cover (34) is provided with a push-in point (52) in the edge region. For opening, this push-in tab (51, 52) must first be torn open, followed by the tongues (61, 62). The tongue possesses a push-in opening (63) in the region of the closure tab part (62). For closure, the point (52) of the push-in tab (51) is pushed into this opening (63), after the tongue (61, 62) has been brought into its original position. As a result, a dust-proof recloseable discharge opening is obtained on the blank, with no additional material, merely by means of perforation lines and fold lines. <IMAGE>
