A container is made of cardboard or the like material-and a pattern or blank from which said container is assembled-and has walls which are joined intimately to a base, a lid flap or flaps on one or one pair of these walls surrounding an opening to the container interior, and lying transverse to that lid flap, dust flaps which when the container is closed face the inner side of the lid flap/flaps. Said container is intended for contents of a finely divided form which could give rise to dust, and is able to prevent this dust formation. To this end the edges at the sides of the dust flap extend on both sides beyond the delimiting wall section a distance from the related fold line to produce peaklike areas; each of which is delimited by a curved contour and are joined to another wall which is adjoined to and is at an angle to that wall section, the edge at the side of the dust flap featuring a radial curvature at least in the region next to the fold line. Further, the leading edges of a pair of dust flaps which feature slits at the leading edge should support the inner surface of the lid flap/flaps; the leight of the dust flaps should be less than half that of the dust flap/flaps. |
