    The invention relates to the field of 'containers, in particular to a folding box for fruits and vegetables.
    Known folding box for fruits and vegetables, including parallel j lateral and transverse folding walls, two bottom parts connected to the side walls by fold lines, one of which has a protrusion for connection with the other bottom part [1].
    The disadvantages of the known box include the fact that under the load created by the contents of the folding box, the total weight of this content must be perceived by the bonding of the bottom parts, and if the contents have moisture, there is a danger of damage. bottom, and. making the bottom of two parts overlapping one another, 20 there is a relatively large waste cardboard, as the part intended for the bottom, strongly protrudes beyond the other parts. In addition, such folding boxes in an empty 25 state are folded diagonally and in a straightened state, before filling, have poor shape stability and are prone to folding.
    The purpose of the invention is the prevention of bending of the bottom.
    This goal is achieved in that in a folding box for fruits and vegetables, including parallel side and transverse folding walls, two bottom parts connected to the side walls by folding lines, one of which has a protrusion for connecting to the other bottom part, the bottom parts are provided with additional connecting protrusions having a bend line. located ^ at an angle of 45 relative to the connection line of the side wall with the bottom part, while the additional connecting protrusions are made with zabzra relative transverse walls of the box. , '
    Figure 1 shows the workpiece (cutting,) in a flat position ’, in figure 2 a partially straightened box, in a perspective view; in Fig. 3 folded box, in a perspective view, in Fig. 4 a fully straightened box, cross section figure 5 is the same, in a perspective view.
    Figure 1 shows the blank 1 for the manufacture of an open top folding box cut from a strip of cardboard. The blank 1 comprises a first side wall 2 and a second side wall 3, which in the straightened position of the box form parallel walls. Both side walls 2 and 3 are bent along the main line 4 of the bend, so that they lie on one another.
    The first bottom part 5 is connected with the side wall 2. The second bottom part 6 is connected. Along the fold line 7’, with the second side wall 3.
    The first part 5 of the bottom has a connecting protrusion 8, which has a fold line 9. The fold line 9 forms an angle of 45 ° with the fold line 7. A similar connecting protrusion 8 is located at the other end of the first bottom portion 5. These connecting protrusions 8 are connected by fold lines 10, perpendicular to the fold lines 7 of the first bottom portion 5. Line ba defines a bend of the protrusion 8 of a rectangular shape. The fold line extends the short rectangular wine 12 of the side wall with the long side wall 2. A similar fold line 11 connects at the other end of the side wall 2 a second rectangular half 12 of the side wall of the same length with the side wall 2, forming transverse folding walls of the box.
    Fold lines 10 form a straightforward continuation of fold lines 11.
    On one of the halves 12 of the transverse wall, a stripe-shaped adhesive connecting protrusion 13 protrudes, connected to this half 12 of the transverse wall by means of a fold line 11 parallel to a similar fold line 11, on the other side of the side wall 2.
    > With SGI11 Soepolo40
    Between the bent protrusion 8 and half 12 of the transverse wall there is a gap reaching the line 10 of the fold. Is there a similar gap at the other end of the first part of the bottom 5 On the opposite side of the bend main line 4 there is another similar rectangular half wall 14 of the transverse wall connected by the bend line 15 to the side wall 3. At the other end of the side wall 3 there is a second half of the transverse wall 14 connected by the bend line 15 to the side wall 3. Straight line continued fold lines 15 are indicated by fold lines 16. The fold line 17 is located at an angle of 45 ° to the fold line 7. The fold line 16 is shorter than half the width of the bottom. Between the bend line 16 and the bend line 17 there is a quadrangular connecting piece 18. The bent edge 17 and the gap parallel to the bend line 7 limit the folding valve 19 on both sides,
    At the other end of the second bottom there is a similar fold, made in the form of a linear extension of the line and separates half of the transverse wall 14 from the folding valve 20.
    The bend line 21 forms an angle of 45 ° with the bend line 7. The fittings 22 and 18 are delimited externally by obtuse cutouts. The fold line 23 located outside the bottom portion 6 is parallel to the fold line 7 and forms a strip-like adhesive joint protrusion 24.
    When the workpiece is folded along the main fold line 4, then both long side walls 2 and 3 and the halves 14 and 12 of the transverse walls, on the one hand, and similar parts of the transverse walls, on the other hand, are located one above the other.
    Bending lines can be obtained by forming grooves or by perforation, due to which bending resistance is reduced in these places in comparison with the rest of the material and therefore the parts are easily bent.
    i A folding box is manufactured as follows.
    Bendable valves 19, 20, 25 are 180 ° bent along fold lines 9 and 16.
    After that, these bent parts of the top are covered with glue. Then, in addition, both bottom parts 5 and 6 bend upward along the fold line 7. Due to this, the bendable valves 19, 20, 25 in part 6, previously coated with glue, line 6 of the straight line 15 fold, touch the opposite halves, 12 and 14 of the transverse walls and firmly adhere to them. The lateral glued protrusion 13 is folded along the bend line 11 by 180 ° and its surface located on top S is covered with glue. Also, the glued protrusion 24 of the bottom part 6, which is parallel to the fold line 7, is covered with glue on its top 1 · surface.
    After that, both side walls 2 and 3 are bent lapwise along the main fold line 4. The adhesive protrusion 13 is glued to the outer part 15 of the half 14 of the transverse wall and, in addition, with the help of the adhesive protrusion 24 the free ends of the bottom parts 5 are connected to each other and 6. The collapsible box is in the finished ”folded state and can be straightened for use after a slight pressure is applied to both ends.
    M
    When straightening the folding box, the acute angle between the halves 12 and 14 of the transverse walls increases. Due to this, the folding valves 19, 20, 25, glued to the halves 3 »12 and 14 of the transverse walls, press the bottom parts 5 and 6 down, which is caused by the geometry of the inclined bending lines 9, 17 and 21. However, the bottom parts 5, 6 cannot bend beyond their horizontal position, as they are supported by fold lines 10 and 16. During the straightening process, obtuse cutouts in the connecting parts 18 and 22 slide along the edges of the bend 9. The angles formed between the protrusion 24 of the bottom part 6 and the connecting protrusions 18/22 easily press the slightly elastic bending part 5 towards the beginning of the straightening process bottom, which causes a snap action, so that the box remains standing after it is straightened.
    n S0
    After straightening, half of the 12 and 14 transverse walls are very slightly curved outward, which is due to the residual self-stress of the cardboard. Meanwhile, it is possible to give the folding box a shape 33 in which the transverse walls would be located exactly at right angles to the side walls 2 and 3.
    The lap joints at the glue protrusion 13 can be displaced in the direction of the outer half 14 of the transverse wall, taking into account that the protrusion 13 is wider, and the half 42 is already narrower or vice versa, the glue protrusion 13 is connected to the outer half 14 of the transverse wall. Next, glue is applied to the opposite sides of the valves 19, 20, 25. The proportions of the workpiece can vary, depending on the required capacity and the type of product filling the box. On this basis, you can get low or high, long or short folding boxes.
    Since both bottom parts 5 and 6 are connected with the halves 12, 13, 14 of the transverse walls, these folding boxes can be filled, for example, with fruits or vegetables that have significant weight, and the possibility of opening (breaking) the bottom down is excluded. The bottom deflection is also hindered by the position that both parts 5, 6 of the bottom are glued together in their middle region and therefore in this region three layers of cardboard are placed one above the other, which is similar to the use of stiffeners.
    When the folding box is aligned by applying pressure (pressing) to the short parts of the side walls, the bottom parts automatically take their initial position.

On the opposite side of the main fold line there is another similar half transverse wall 1A half connected by a fold line 15 to the side wall 3. At the other end of the side wall 3 there is the second half Ut transverse walls connected by a fold line 15 to a side wall
    [3]
    3. The straight extension of the fold line 15 is indicated by the fold line 16. The fold line 17 is angled to the fold line 7. The fold line 16 is shorter than half the bottom width. Between the fold line 16 and the fold line 17 is a quadrilateral connecting piece 18. The foldable edge 17 and the gap parallel to the fold line 7 limit the folding flap 19 on both sides. At the other end of the second part 6 of the bottom there is a similar fold line 16 a linear extension of the fold line 15, and separating the half of the transverse wall 14 from the folding valve 20. The fold line 21 forms an angle of 45 ° with the fold line 7. The fittings 22 and 18 are limited outside by obtuse cuts. The fold line 23, located outside the bottom part 6, extends parallel to the fold line 7 and forms a strip-shaped adhesive connecting protrusion 24. When the workpiece is folded along the main fold line 4, both long side walls 2 and 3 and half 14 and 12 of the transverse walls, on the one hand, and similar parts of the transverse walls, on the other hand, are located one above the other. Fold lines can be obtained by forming a groove or by punching, whereby the resistance to bending is reduced in these places compared to the rest of the material and therefore the parts are easily bent. The folding box is manufactured as follows. The flap flaps 19, 20, 25 are bent 180 ° along the fold lines 9 and 16. After that, these folded parts are covered with glue on top. Then, in addition, both bottom parts 5 and 6 are folded up, along the fold line 7. Due to this, the adhesive valves 19, 20, 25, which are previously coated with glue, come into contact with the opposite half 12 and C of the transverse walls and are firmly glued to them. The side glued protrusion 13 is folded down along the fold line 11 by 180 and its langled on top of the surface is covered with glue. Also, the glued protrusion 2k of the bottom part 6, which is located parallel to the fold line 7, is covered with glue on its top surface. After that, both side walls 2 and 3 overlap, along the bend main line k .. The adhesive protrusion 13 is glued to the outer part of the half H of the transverse wall and, moreover, the free ends of the bottom parts 5 and 6 are joined together by means of the adhesive projection 2 The folding box is in the finished folded state and can be. straightened for use after slight pressure is applied to both ends. When straightening the folding box, the acute angle between the halves 12 and 1 of the transverse walls increases. Due to this, flap valves 19, 20, 25, glued together with the halves 12 and T of the transverse walls, press down the bottom parts 5 and 6, which is caused by the geometry of the inclined lines 9, 7 and 21 of the fold. However, the bottom parts 5, 6 and iv can be bent beyond their horizontal position, since they are supported by fold lines 10 and 16. During the straightening process, the obtuse notches in the connecting parts 18 and 22 slide along the edges of the fold 9. The angles formed between the protrusion 24 of the bottom 6 and the connecting projections 18, 22 are easily pressed towards the beginning of the straightening process. part 5 of the bottom, which causes a snap action, due to which the box remains standing after its straightening. After straightening half of 12 and C, the transverse walls are very slightly curved outwards, which is caused by the residual self-stress of the cardboard. Meanwhile, it is possible to impart a folding box of forms in which the transverse walls would be precisely at right angles to the side walls 2 and 3. 0 The junction protrusion of the glue ledge 13 can be displaced in the direction of the outer half 1 of the transverse wall taking into account that the protrusion 13 is made wider, and the half of k2, respectively, already or vice versa, the adhesive protrusion 13 is connected to the outer half 14 of the transverse wall. Next, glue is applied to the opposite sides of the valves 19, 20, 25. The proportions of the workpiece can vary, depending on the capacity required and the type of product that fills the box. On this basis, low or high, long or short folding boxes can be obtained. Since both bottom parts 5 and 6 are connected to the halves 12, 13, I of transverse walls, these folding boxes can be filled, for example, with fruits or vegetables of considerable weight, without the possibility of opening (breaking the bottom down. Bottom deflection the fact that both parts 5, 6 of the bottom are glued to each other in their middle area and therefore in this area there are three layers of cardboard arranged one above the other, which is similar to the use of stiffening ribs, prevents the folding box by applying pressure (pressure) to short parts of the side walls, the bottom parts automatically take up their original position. Claims Foldable box for fruits and vegetables, including parallel side and transverse folding walls, two bottom parts connected to the side walls through a fold line, one of which has a protrusion with the other bottom part, characterized in that, in order to prevent the bottom from arching, the bottom parts are provided with additional connecting protrusions,) having a fold line located at an angle kS with respect to l The connection of the side wall with the bottom part, with additional connecting protrusions with a gap relative to the transverse walls of the box.
