Definitions

  • the invention relates to a folding box with base and side walls, which is made from a blank that has at least eight fold lines, four of which are long fold lines arranged between the base and one side wall, which meet and intersect at an angle of 90 °, and two short fold lines on two side parts facing away from each other, these short fold lines of crossing points, at which the long fold lines intersect at an angle of 90 °, run at an angle deviating from 90 ° relative to the long fold lines of the blank.
  • Such a folding box is known from GB-A-2 084 961.
  • Known folding boxes have a bottom and four side parts.
  • the blank produced by punching has corresponding tabs which are erected and then connected to one another by adhesive bonding, insertion or the like.
  • the boxes are either prepared in the form of a box in the manufacturing plant or else the consumer in a disassembled, flat state supplied, which then assembles the box with special joining or tacking systems.
  • cuts are often made to a considerable extent when the required blanks are punched.
  • the storage of finished or semi-finished folding boxes requires a considerable amount of space. After all, it is often tedious for the consumer and associated with relatively high costs if the folding boxes are only completed at the consumer.
  • Folding boxes are also known which have no stitching and gluing points, but they are provided with folding patterns which are so complicated that they cause an increased tool expenditure for the manufacturer and the user has to cope with not inconsiderable problems during assembly.
  • the invention has for its object to provide a folding box that can be erected quickly in the prefabricated state and can be folded up again just as quickly.
  • fold lines each extend all the way to the edges of the blank and divide connecting surfaces, each of which is delimited by a long and a short fold line and by the edge of the blank, and after the folding box has been erected are firmly connected to adjacent sections of other side parts.
  • the invention can be realized with a blank which consists of cardboard, coated cardboard, plastic or the like.
  • the cut has only relatively few fold lines and is therefore easy to produce.
  • the connection surfaces can be attached to adjacent surfaces by gluing, stapling, stapling or the like.
  • An advantage of the invention is that the folding box can be erected simply and quickly.
  • the folding boxes according to the invention can be used to hold food, fruit, vegetables, sweets, nuts or the like, but also to hold office utensils such as rubber rings, paper clips or the like. Their length, width and height can be selected within wide limits.
  • the blank has a rectangular, for example square, shape, so that the blank can be punched out without waste.
  • at least two edges of the blank facing away from one another have a flat circular arc section. This makes it possible to produce folding boxes, the upper edge of which is curved in the erected side parts. Instead of a circular arc section, however, a wave shape or a zigzag shape or the like can also be selected, which then determines the upper edge of a side part of the finished box.
  • the end points of the short fold lines of a side part, which end at the edge of the blank can meet at an edge point, so that the connecting surfaces divided by these fold lines are triangular.
  • the end points of this short fold line at the edge of the blank can also be at a distance from one another, so that there is a multitude of box shapes.
  • two side parts which face away from one another and have no short fold lines are folded inwards and lie on a base part of the box, the connecting surfaces being fastened to the adjacent sections.
  • the folding box is then in a flat state and can be stored in this state. This reduces the total height of the prefabricated folding box to be stored to about twice the material thickness of the material used for the production.
  • the folding box can be erected by simply swiveling the folded side parts.
  • the folding box according to the invention can be brought back into a flat state by pivoting back opposite side parts around the long folds into the plane of the bottom part.
  • the blank for forming the side parts is divided into three equal parts by at least two long folds, so that the height of the side walls of the finished box corresponds to the width of the base part.
  • the blank also has an additional central fold running through the center of the base part. As a result, the box can be folded even smaller in the prefabricated state.
  • the punched blank is of any size, rectangular and square. It has long fold lines A, B, C, D, which cross at right angles, and short fold lines 13, 14, 15, 16, that of crossing points 37 of the long fold lines A, B, C, D at an angle other than 90 ° , e.g. B. 45 °, to the adjacent edge 38 and meet at an edge point 39, where they enclose an angle of 90 ° in the illustrated embodiment. They divide from the side parts 1 and 2 of triangular connecting surfaces 17, 18, 19, 20.
  • connection surfaces 17 to 20 or at the edges thereof are folded inwards along the folds A and B until they lie flat on a base part 5 (FIG. 2 ).
  • the triangular connecting surfaces 17 to 20 lie on a triangular part of the adjacent surfaces 21, 22, 23 and 24 of the side parts 3 and 4 and are permanently attached there.
  • connection surfaces 17 to 20 can be attached to the adjacent surfaces 21 to 24 by gluing, stapling, stapling or the like.
  • the size of the base part 5 can vary in length and width in individual embodiments of the invention and thus the height of the side parts changes with the same outline of the blanks. In the embodiment shown in FIGS. 1 to 4, the bottom part 5 is twice as wide as the side parts 3 and 4, which have the same width.
  • a finished folding box can be put back into the flat state if the side parts 3 and 4 are pressed down onto the bottom surface 5 or the side parts 1 and 2 outwards into the plane of the bottom surface 5.
  • M in the drawings denotes the center line of the blank and the finished box.
  • FIGS. 5 and 6 show further embodiments of a blank with different arrangement of the fold lines. These figures show the variability of the width, length and height of the side parts 1 to 4 and the bottom part 5 and FIGS. 5 and 7 other angles between the short and the long fold lines.
  • the fold lines are arranged so that the side parts 3 'and 4' have the same width as the bottom part 5 '.
  • the side parts 3 'and 4' overlap, since the bottom part 5 'is as wide as a side part 4' or 3 '(FIG. 8).
  • the outer edges 31, 32 of the side parts 3 'and 4' run in a flat circular arc section or in another shape deviating from a straight line, e.g. B. in wave form or roof shape. The upper edge of the side parts then receives this shape (FIG. 9).
  • the ends 35 of the arcs lying on the edges of the blank are, for example, at a distance of half a side part width of the side parts 3 'and 4' from the corners 11 and 12. This distance determines the height of the side walls of the finished box at the relevant point.
  • the circular arcs 30 and 31 form a small amount of waste.
  • This folding box according to FIGS. 7 to 10 is erected in the same way as in the embodiment according to FIGS. 1 to 4.
  • a folding box according to FIG. 9 is obtained in which the sections 23 ', 24' and 2 'or 21 ', 22' and 1 'partially overlap so that these walls of the box are stiffened.
  • sections 23 'and 22' are partially between sections 2 'and 24' and 1 'and 21', respectively, so that sections 22 'and 23' are also held in place by friction. This leads to additional stiffening.
  • This folding box can also be quickly put back into a flat condition if the side parts 1 'and 2' are pushed back into the plane of the base part 5 '.
  • a middle fold line 33 is also provided along the center M of the base part 5 or 5 ', through which the folding box is halved and these two halves are congruent with one another in the prefabricated state (FIG. 10).
  • the folding box can be assigned a second container, which is manufactured according to the same principle, as a lid.
