    Packing container blanks for gable-top packages are cut out of a material web which, up to now, has caused an appreciable amount of waste material, since the edges of the blanks are irregular and cannot be "dovetailed" into one another. In accordance with the invention a packing container blank is provided with partly straight, parallel lateral edges (9, 10), partly transverse edges (11, 12) which are profiled according to a regular pattern which is repeated over the width of the blank. As a result the profiled edges of the blanks too can be formed without wastage.

    The invention relates to the preparation of a packaging container, in particular a sealed container, with a dual-slope upper part for a fluid.
    The aim of the invention is to reduce the waste of the packaging material to be cut.
    FIG. 1 shows a packaging container; in fig. 2 — the upper portion of the packaging container (with dashed lines indicating the j-lines along which folding is performed) —Fig. 3 is a portion of the lower end of the packaging container f in FIG. 4 - container preparation; in fig. 5 is the same, the second embodiment (the adjacent edges of the adjacent blanks are shown by thin lines).
    The packaging container (Fig. 1) is a parallelepiped with a comb-shaped upper part. Mostly | The packaging container is formed by four rectangular side walls, which are separated from each other by 2 fold lines. At the upper end of the side wall panels on one side there are inclined towards each other main basic panels 3 of a rectangular shape, and on the other hand there are folding panels 4 bent between the main panels. The main top panels 3, as well as folding the panels 4, are separated from the side walls 1 by a transverse fold line 6. On top of the main top panels 3 is located popesl

    The river sealing rib 5 formed by the upper ends of the upper panels glued together to form a liquid-tight seal (FIG. 2).
    Like the upper part of the packaging container, its base also contains a series of panels separated from each other by fold lines, which, after folding and gluing, form a liquid-tight flat base. In the lower part of the packaging container there are two opposite main bottom panels 7 of rectangular shape. Inside, there are folding triangular shaped panels 8 which are glued to the main bottom panels 7.
    The packaging container blank is cut from a wide web of material according to the edges shown in the drawing (the location of the adjacent blanks is shown in Fig. 4 with thinner contour lines). The preform for the packaging container is cut from a material and has four sides, and it contains two straight parallel longitudinal edges 9 and 10 and two transverse edges 11 and 12 located between the longitudinal edges 9 and 10. The transverse edges 11 and 12 are not straight lines. , and are profiled according to a pattern that repeats across the strip of the workpiece. Parallel to two longitudinal edges 9, 10, longitudinal fold lines 2 extend along the entire length of the packaging container blank, dividing it into four wall panels 13, each of which has two parallel longitudinal edges or fold lines and two transverse edges coinciding in position with transverse edges 11 and 12.
    Steppe panels 13 are divided into two main types: A and B (Fig. 4). On one side of one of the two outer wall panels 13, there is a longitudinal i sealing loop 14, separated by one of the fold lines 2. The panel 14 is glued to the opposite wall panel 13A along the longitudinal edge 9 when the tubular shape is attached to the blank of the packaging container material.

    .4fl And from the wall panels 13 there are D M (; Listed fold lines that divide said wall panels into separate panels to be - then - folded or glued when forming different wall panels of the packaging container when the blank of the material for the packaging container turns into finished packaging container. With the help of an upper transverse fold line 6, which runs through all wall panels 13 at right angles to their fold lines, and a corresponding lower transverse fold line 15 located in the center of the bo The new walls 1 are separated from the wall panels which form the upper part and the bottom of the packaging container. Thus, each of the two wall panels 13A forms a side wall panel together with the main bottom panel 7, having a rectangular shape and separated from its lower end by the lower a transverse fold line 15, and folding panels 4, separated at the upper end of the side wall panel 1 by an upper transverse fold line 6. The folding panels 4 consist of a central folding panel 4.1 4.1 and two panels 4.2 located on both sides of the central folding panel 4.1.
    Each of the two wall panels 13B also has a central panel of the side wall 1, which in its lower part is separated by a lower transverse fold line 15 from the folding panels 8, the latter, like the panels of the upper part of the workpiece, contain a central panel 8.1.and panels 8.2 located along both sides of the central panel. At the upper end of the sidewall panel 1, the wall panels 13B comprise a rectangular main panel 3 for the upper part, which is separated from the panel of the side wall 1 by an upper transverse fold line 6, on top of the main panel 3 of the upper part of the packaging container and the top folding panel 4 an additional sealing panel 16 extending in the transverse direction, which is used to glue the upper part of the package and to form a pack
    stitching rib 5. Usually, additional folding lines (not shown) are provided in the packaging container blank to form, for example, by folding the drain tip of the finished packaging container.
    The upper as well as the lower transverse edges 11 and 12 have a profile made in accordance with a systematic pattern repeated throughout the entire strip of the workpiece. Each transverse edge 11,12 passes, moving, along boundary lines 17, located at a short distance from each other. The two faces of line 17 meet or intersect longitudinal fold lines 2, with the result that these boundary lines break into several smaller parts. These parts are usually located opposite one another, which is why the boundary lines are straight and unbroken, while it is also possible that some parts of each boundary line may be slightly displaced one against the other, for example, when gluing, when it is undesirable to place lines the edges of the preform are directly lered to the other, which can otherwise be said negatively on the density of the joint of the finished packaging container. The magnitude of this displacement is insignificant (1-3 mm) and therefore the boundary lines can be considered practically as straight lines. Thus, each of the transverse edges 11 and 12 extends along wall panel 13B, extending partially along the adjacent wall panel 13L along a second boundary line 17.2, partly along inclined transition lines 18, which join together these two boundary lines 17.1 and 17.2. Such a pattern is repeated on opposite edges of the preform, with the result that two wall panels 13B are delimited at both ends by straight sections of transverse edges 11, 12 that extend along the boundary lines 17.1, and two wall panels 13A along the central section 19 at both ends transverse edges 11, 12, running along two boundary lines 17.2, and on each side of the central section 19, inclined transition lines 18,

    Thus, on each wall panel there are protrusions and depressions, the lower protrusions have bevels, and the depression formed in the upper part of the panel has inclined sections along the edges intersecting with the upper borders of the protrusions of the adjacent panels along the fold line, with This profile of the edge of the upper part of the panel coincides with the profile of the edge of the lower part.
    In accordance with the second production variant of the packaging container blank, the profile of one transverse edge can be applied to the opposite transverse edge profile while maintaining the overall identity of the specified drawings (Fig. 5 shows the layout of the packaging container performed in the second version).
    Similar to the blank shown in FIG. 4, the blank shown in FIG. 5, is cut in such a way that two parallel longitudinal edges 9, 10 delimit the workpiece in one direction, and the profiled transverse edges 11, 12 in the opposite direction. The blank in FIG. 5 has the same pattern of fold lines as the blank shown in FIG. And those. it is demarcated by means of common parallel fold lines 2 into four wall panels 13, adjacent along its longitudinal directions, two identical 13C and two 13D. However, unlike the packaging container blank shown in FIG. 4, in the blank under consideration, the main panels 3 for the upper part of the container and the main bottom panels 7 are located at opposite ends of one and the same wall panel of type C, and the folding panels of the upper and lower part are located at opposite ends of the other wall panel of type D.
    The upper 11 and lower 12 p- / pepper edges of the packaging container blank are shaped according to the same pattern, which is systematic and repeats throughout the entire strip of the blank. However, the profile pattern, performed on the transverse edge 11, is displaced relative to the profile pattern, performed on the opposite transverse edge 12, so that each
    A separate wall panel at its one end is delimited by a transverse straight edge, and at the other, by a profiled one. As a result, the edge profile pattern at one end of each wall panel has an additional portion thereof at the opposite end of the adjacent wall panel (according to the first embodiment, the edge profile pattern at the end of each wall panel is complemented by an edge profile pattern at the opposite end same wall panel) i.e. the pattern of the edge profile is the same on both edges, but at the same time it is offset by the width of one wall panel.
    The profile of the transverse edges 11 and 12 has the same systematic pattern as the profile of the corresponding transverse edges of the blank of the packaging container shown in FIG. 4. These edges are located offset along the boundary lines 17.1 and 17.2, together with inclined transition lines 18 located between them. At the upper end of the packaging container blank, the transverse edge 11 extends along one boundary line 17.1 above wall panels 13C, extending above wall panels 13D partially along the other boundary line 17.2, partially along the inclined transition line 18 that connects the central part of the edge line extending along boundary line 17.2, with intersection points 20 between boundary line 17.1 and fold lines 2 dividing panels 13. At the lower end of the blank, the two wall panels 13D have transverse straight edges 12 Only the boundary line 17.1, and the two wall panels of the 1ZS have edge lines that extend over the central section 19 along the boundary line 17.2, extending from both sides of this central part towards the intersection point between the boundary line 17.1 and the fold lines 2.
    The presence of a special pattern of two transverse edges 11 and 12 allows for the blank preparation of packaging containers made of roll material without waste aa of about 1; CM with a cutting tool, KompMti simultaneously forms

    one edge on the first blank of packaging material and a greater or lesser part of the opposite edge of the adjacent adjacent blank.
    The blanks from the packaging material, made in two variants, are cut with different patterns of edge profiles.
    The blank of the first embodiment (Fig. E) is cut with two rectilinear longitudinal edges 9,10 parallel to the longitudinal direction of the material web, assuming that the material web moves vertically in the plane of the pattern. Since the transverse edges 11 and 12 of the blank of the packaging container material are cut out according to systematic identical pattern patterns, which are also located opposite each other, the profiled edge of one blank coincides with the opposite profiled edge of the subsequent (previous) blank, which allows one transverse cutter located above the packaging material web at the same time cut the lower transverse edge 12 of one blank and the upper transverse edge 11 next uyuschey her preform packaging containe inequality. In the process of cutting these blanks, no waste material is generated, since the edge profiles are completely identical.
    The longitudinal edges 9 and 10 of the blanks are straight, so it is also possible to cut the longitudinal edge of one sheet at the same time as cutting the longitudinal edge of the opposite adjacent sheet without any loss of packaging material, which allows a random number of blanks to be positioned throughout the entire strip. Canvas material.
    According to the second production variant of the blank, the web of material from which the blank of the packaging container is cut is also arranged vertically relative to the plane of the pattern, i.e. parallel longitudinal edges 9 and 10 and fold lines 2 are at an angle of 90 to the longitudinal direction of the strip of material. Although the profiled transverse edges 11 and 12 do not directly correspond to the profiles of the edges of the opposite side of the adjacent workpiece, the adjacent workpiece should be displaced by some distance, which corresponds to the width of one wall panel 13. As a result of this displacement, an arbitrary number of workpieces can be placed across the entire width of the web of material and cut out by means of common cutting devices that simultaneously form the upper transverse edge 11 of one workpiece and the opposite end river edge 12 adjacent to the workpiece. In this case, some material loss is unavoidable in the areas of the outer edges of the material web, since they are straight and do not have a profile corresponding to the edges 11 and 12 of the packaging container blank. Cutting can be carried out without loss of packaging material in the manufacture of successive blanks arranged adjacent to each other on the material web, if this is followed by a step line, which is determined by the longitudinal edges of 9.10 sheets of packaging material arranged adjacent to each other. with a friend.
    The location of the blank for the packaging container on the web of material and, therefore, the choice of the first or second variant of manufacturing the blank is determined, among other things, by the way the direction of the fiber of the packaging material relative to the blank is to be placed. The laminate from which the blank for the packaging container is made comprises a central carrier layer of paper. During paper manufacturing, the individual fibers forming the paper are more or less automatically oriented in the direction of the paper unloading from the paper making machine, i.e. these fibers are arranged longitudinally relative to the paper web. In the blank shown in FIG. the fibers are oriented with their longitudinal axes in the longitudinal direction of the wall panels 13, i.e. arranged vertically in the finished packaging, and in

    Cooking according to another variant (Fig. 5), such fibers are arranged horizontally relative to the position of the packaging container. Since the latter direction of the fibers allows for greater rigidity of the packaging container and, consequently, greater strength, it is more preferable. However, the orientation of the fibers of the packaging material in the vertical direction, used in the manufacture of packaging for packaging containers in accordance with the first embodiment of the present invention, provides a simpler formation of the upper opening part of the packaging container. In addition, the use of the first option allows the manufacture of packaging containers at a higher speed, since in this case the distribution of a wide web of packaging material is carried out using parallel arranged cutting devices that can operate at a rather high speed.
