The subject of this invention is the foldable packaging intended for storage of products, especially in amounts for a single use. A foldable packaging (1) is formed of the flat template (11), bent and joined at least through the lower fold (61), the side fold (62) and the upper fold (63) and has two main walls (21, 22) and two side walls (31, 32) joined with the bottom (7). The flat template (11) has four main vertical bending lines (41, 42, 43, 44), one main horizontal bending line (72), two vertical side-wall bending lines (51, 52), one horizontal lower-fold bending line (71), one horizontal upper-fold bending line (73) and diagonal bottom bending lines (91, 92, 93, 94). The distinctive features of the foldable packaging (1) are as follows: - the main walls (21, 22) converge at the top the foldable packaging (1) and, on the upper fold (63), meet the upper edges of the side walls (31, 32), which are curved on the vertical side-wall bending lines (51, 52); - the side walls (31, 32) have diagonal side-wall bending lines (81, 82, 83, 84), which make - on the flat template (11) - isosceles right triangles with the base lying on the main horizontal bending line (72) and the right-angle vertices lying on the vertical side-wall bending lines (51, 52); - the side-wall bending lines (51, 52) in their upper part are inward bending lines of the foldable packaging (1), and - in the section between the diagonal side-wall bending lines (81, 82, 83, 84) and the main horizontal bending line (72) - are outward bending lines of the foldable packaging (1). |
