A blank of packing for foodstuffs is divided by lines of creasing into large variously-sized sections of quadrangular form and figured valves, which at assembling of packing form side and end walls respectively, it containing sections (3, 5, 7, 9) of rectangular form and sections (2, 4, 6, 8) in the form of trapezoids elongated along horizontal, in this case the width of sections (5, 9) is somewhat grater than the width of other sections. Quadrangular valves fit closely from both sides to sections (5, 9), while from both sides on the extension of sections (2-4), (6-8) with similar lines of creasing are formed paired valves, moreover one of them has the form of an octagon, on free side of which figured lug is made which is isolated by the line of creasing, and the second trapezoid valve has a cut on the average side of basis intended for interaction with figured lug at assembling of packing. On the surface of the blank two horizontal rows of gaps are made, which form a tear-off strip with valve at the end for separation of the smaller part of packing, which fits closely to the end. |
