    A container of thermoplastic coated cardboard has a bottom closure of a known type having two triangular infold panel portions, a pair of triangular fold-back panel portions lying on either side of each triangular infold panel portion and two outer bottom closure panels (54, 56) overlapping each other in the completed bottom closure. In order that the free outer edge of the lowermost (54) of the two outer bottom closure panels shall have no raw edge exposed to the inside of the container, the bottom closure panel (54) has a fold-back tab (60) which is folded back onto the outside surface of the bottom closure panel (54). According to the invention the outer edges (64, 66) of the bottom closure panel (54) on either side of the fold-back tab (60) are offset from the outer edge (68) of the fold-back tab (60) towards the associated side wall panel (18). Thereby it becomes possible to perform the folding back of the fold-back tab (60) by means of the edge (70) of the outermost bottom closure panel (56), the consumption of cardboard being at the same time reduced.

    The invention relates to the field of packaging and can be used in the manufacture of containers for storing containers.
    The aim of the invention is to reduce material costs and simplify the billing of the workpiece by improving the design of the bottom gate formed by the lower utapans, eliminating the inside edge of the free edge of the free gate on the bottom gate.
    Fig. 1 shows a blank of a folding container for a liquid, viewed from the side forming the inner surface of the container; Figs 2 are also at the stage of formation of the bottom gate; . 3-section A-A in FIG. 2, before welding the bottom closure; in fig. 4 - bottom of the tank, bottom view; in fig. 5 shows a section in FIG. 3,
    The liquid storage container blank is a sheet covered with a thermoplastic layer, with 1 perhibitor lines deposited on it, dividing the sheet into four side CTBJi 2-5, adjacent upper 6 valves and lower 7 7, slanting to form a top (not shown and bottom gate 11, respectively. Fold lines 1 also define a section 12 adjacent to one of the side walls, for example wall 5, along its height to form side gate 13. In each of the lower valves 8 and 10, adjacent to the two opposite side Walls 3 and 5 are formed by sloping lines 14 ne-regibed in three sections, respectively 15-17 and 18-20, having the form of equilateral triangles.The middle ones of them 16 and 19, which are bent inward, adjoin the side walls 3 and 5, respectively.

    Each of the other two triangular sections 15, 17 and 18, 20, placed from the outer rtoron, the sections 16 and 19 bent inward, are located on the sides of the latter. At the same time, one of the two other lower valves and 9, located on the outer side of the bottom gate 11 - valve 7, has a height that overlaps the valves 7 and 9 with an overlap, and is provided with a bent outward angle. 21 located in the middle part of the valve. 7 and separated from him

    Edges of marginal sections 23 and 24 of valve 7, are located above on both sides
    5 bend outward section 21; shifted in height towards the side wall 25 of the line 22, re-bending the separating bend-out section 21 from the valve 7, placed on the level of the specified edges of the edge sections 23 and 24.
    To form a collapsible liquid container, the billet is folded along the lines of the aggregate and in any practical way of welding the coatings, for example by heat or sound, the section 12 is connected to the side wall 2, the upper 6 and the lower 7 to 10 valves .M. The logging takes the form of tr: rectangular section,
    In order to form the dairy gate 1 1 g, the 5-gauge portions 16 and 19 are bent inwards around the bend lines 1. The triangular sections 15 and 17 of the valve 8 and the triple sections 18 and 20 of the valve 10 are folded along oblique bend lines 14 and separated from the sections 16 and 19.
    Valves 7 and 9 are also folded back from the sides of ÜE: sides 2 and 4 along the bend lines 1. Section 21 is folded over the bend line 22.
    When the edges of the edge portions 23 and 24 of the valve 7 reach position 5 until; 1 is shown in FIG. 2, the free Kpaii valve 9 acts on the ya section 21, bending it back to the nasal side of the edge section 23, and the free edge of the valve 9 covers the other side of the p-gastka 21. which is covered with the inflection line 22 (FIG. 1 ). Then, by welding in any way, the bottom atvor 1 1 is formed in the same way.

    the walls, the implementation of these sections in the form of equilateral triangles, the middle of which, bent inward, is adjacent to the side wall, and the other two triangular sections, located on the outside of the inwardly curved section, are located on the sides of the latter, one of the other two lower valves, placed on the side of the bottom closure, has a height that ensures overlapping of the valves and is provided with a bent outward rectangular section located in the middle part of the valve and is separated

    and the width of the section is less than the width of the valve, provides a sealed container formed by the workpiece. .
    The fact that the edges of the edge sections of the outer valve, placed along both the CTopoHti of the part that is bent outward, is shifted in height towards the side
    the walls, and the kink line separating the foldable section from the valve, is placed at the level of the marginal sections, which reduces the material consumption and simplifies the folding of the workpiece.
