Abstract

1. A stackable container (1) which has been erected from a blank and which has a quadrilateral container floor (2) which is surrounded on all sides by an upwardly conically opening container wall which, in its corner regions, has triangular fold portions (8-14) which extend from the corners (7) of the container floor (2) and which, partly over themselves and partly over quadrilateral wall regions (3, 4, 5, 6) disposed therebetween, form transitional portions between these wall regions which are folded so as to comprise three layers of material, characterized in that seven fold portions (8-14) are provided in each corner region, adjacent fold margins (17, 21 ; 20, 24 ; 23, 27) being contiguous, and in that the container (1) has a capacity of at least 56 litres.

Description

I1 The invention relates to a container made from a single blank with inflection lines applied to it. The known container blank, which is a sheet with inflection lines deposited on it, dividing the blank into portions forming the bottom, side and end walls and angular portions divided by the inflection lines into three triangular parts to form an angled lock during the formation of the container ij . However, the known capacity does not provide sufficient strength due to the lack of rigidity of the corner locks formed during the formation of the container. Closest to the present invention is a container blank, which is a sheet with inflection lines deposited on it, dividing the blank into areas forming the bottom, side and end walls and corner sections located at each corner of the blank and divided by lines. kinks into triangular parts to form a corner lock when forming the container 21. In a known workpiece, the corner sections are divided by kink lines into five triangular parts, which form corner locks when forming the container, but it does not provide sufficient strength to capacity. The purpose of the invention is to increase the capacity. The goal is achieved by having a container blank. is a sheet with inflection lines deposited on it, dividing the workpiece into areas forming the bottom, side and end walls and corner sections located in each corner of the workpiece and separated by bending lines into triangular parts to form an angle lock when forming the container , each corner section is divided into seven triangular parts, with the inflection lines separating the corner sections alternately located on the upper and lower sides of the workpiece. Figure 1 shows schematically a container blank; in Fig. 2, a bone is made of the angular blank indicated in Fig. 3; mock capacity. 9 A container blank is a sheet with inflection lines applied to it, dividing the blank into areas forming the bottom 1, side 2 and 3, and end and 5 walls and corner sections 6-9, located at each corner of the blank and separated lines MI 10-22 fold into triangular parts to form a corner lock when forming a container. Each corner section 6, 7, 8, and 9 is divided into seven triangular portions 23-29, with the fold lines 10-22 separating the corner portions 6-9, alternately located on the upper and lower sides of the workpiece. The container is added as follows. The side walls 2 and 3 and the end walls 4 and 5 are bent to one side along lines 30, 31, 32 and 33. Then, part 23 of each corner section 6, 7, 8 and 9 is bent to the outside along line 11 of the bend (FIG. one). Part 24 is bent in the opposite direction along line 12 of the bend. After this part 25 is bent inward along the line 14 of the bend, and part 26 is folded in the opposite direction along the line 15 of the bend. This part is located in the middle of each corner section and is transitional when a lock is formed, i.e. half of the part 26 is adjacent to the end, and half - to the side walls. Section 27 is bent along the line 17 of the bend to the outside, and section 28 is bent in the opposite direction along the line 18 of the bend. Then the portion 24 is bent inward along the line 20 of the bend, and along the line 21 the bend section 5 is bent in the opposite direction. Thus, an angle lock (Fig. 3) is formed at each corner of the workpiece. On lines 13, 16 and 19, applied to the workpieces dotted, vertices 30, 31 and 32 interact, bends, and on lines 10 and 22, also marked dotted, a bend of sections 2, 3, 4 and 5 is formed (Fig. , pos.33). The proposed capacity with a capacity of 1 L, made of four-ply Kraft paper with a density of 300 g / m, glued together with dispersed glue, holds a load in the range of 142-143 kg at an ambient temperature of 16 ° C and a relative humidity of 70%.
