Definitions

  • the invention relates to a crate made of cardboard, in particular for fruit and vegetables, with a rectangular base part on which side walls formed by side wall strips are articulated, in the corners between the side walls approaches are hinged to short edges of the side walls, from which parallel folding by multiple folds for the short edge corner supports are formed which project upwards beyond the side walls outside the corner support area.
  • Such climbs are known in multiple embodiments. They are generally used to absorb light vegetables or light fruit and must therefore have a certain stability, i.e. load-bearing capacity and compressibility, as well as torsional rigidity even after exposure to moisture.
  • the corner supports are provided, which are glued to the side walls.
  • An example of such a tray is disclosed in GB-A-927 863.
  • the side walls are double-walled in that a further side wall strip of approximately the same height is articulated on the side wall strip hinged to the base part, which is pressed flat against the first side wall strip when the tray is erected and glued there.
  • the known crates are not suitable for taking larger weights, so that wooden crates are used for heavier types of vegetables and fruit, which are relatively expensive on the one hand and are difficult to print on the other hand.
  • the wooden crates are made from a wooden floor, wooden side walls and triangular wooden corner supports, the connection being made by nailing.
  • a tray which is also provided with corner supports which are formed by multiple folding of approaches of the side walls.
  • the corner supports have the same height as the side walls.
  • the side walls are provided with an upper flange, so that a circumferential edge that reduces the upper opening is created. The flanged edge strips are locked by inserting them into the folded corner supports.
  • the invention has for its object to design a tray of the type mentioned so that the stability and weather resistance is further increased.
  • the crate according to the invention is characterized in that the connecting piece covers the top of the corner support and that the adhesive flap, projecting downwards from the top of the corner support, is glued to the outside of the adjacent side wall.
  • the inventive design of the tray ensures that the corner supports pointing upwards with cut edges are covered so that the corner supports do not soak up water over the cut edges when the tray is once in the rain; on the other hand, by gluing the adhesive flap to the adjacent side wall, a firm corner connection is produced, which makes it difficult to tear off the side wall from the corner support.
  • the width of the first and second fold line of the connecting piece is preferably at least as large as the width of the first and last section of the multi-foldable extension. This ensures that the corner support is completely covered by the connecting piece.
  • the first and last section of the approach forms the connection surface for the gluing with the side walls of the crate that meet at the corner.
  • the adhesive tab fulfills an additional support function if its length is slightly greater than the height of the adjacent side wall.
  • the adhesive flap expediently closes with the lower edge of the side wall, that is to say with the bottom of the crate.
  • the adhesive tab therefore leads to a strengthening of the side wall in the corner area, whereby in particular a significant increase in the crush resistance of the corner supports is achieved.
  • the corner supports are preferably formed in three parts so that they form a triangle.
  • the connecting piece has the shape of a triangle.
  • the tray according to the invention is suitable for high loads and is therefore preferably designed with double-walled side walls.
  • the side wall strips are connected to a further side wall strip articulated on their upper longitudinal edge, which ends in front of the corner support areas of the side walls.
  • the double-walled design of the side walls therefore only happens between the corner supports, but not in the corner support area.
  • the fold line between the two side wall strips is preferably closer to the bottom part than the upper edge of the side wall in the area of the corner supports, so that the side wall has its height in the area of the corner supports, but otherwise has a lower height.
  • This folded bead interferes with the corner support resting on the base part. It is therefore advantageous if the first and last section of the extension on the side facing the adjacent side wall are shorter by the height of the folding bead than the central part of the extension. This shorter design causes the parts of the corner support that lie flat against the side walls to rest on the folding bead, while the middle part of the corner support stands directly on the base part. In this way there is a stable support of the corner support downwards.
  • the side wall strips are articulated with the base part in the area of the corner supports via a counterfold.
  • the creasing is therefore carried out in reverse, i.e. H. the bead is formed on the underside of the bottom part.
  • no folded bead disturbs the support of the corner support on the top of the base part.
  • connection piece can be articulated with the adhesive flap on the short side walls as well as on the long side walls.
  • the material for the adhesive flap is contained in the rectangular piece of cardboard from which the blank is made.
  • the long side walls are strongly stabilized, and large leverage forces can act on them.
  • three layers are then glued together for the long side wall, namely one position of the corner support, the single-layer side wall in this area and the adhesive flap.
  • the connection piece is articulated with the adhesive flap on the long side wall, the long side in the corner support area is made of two layers, while the end face is made of three layers. While the stability on the long side wall is preferable for reasons of stability, the gluing on the front wall can have advantages when mechanically erecting and gluing the crates.
  • the blank shown in FIG. 1 consists of a rectangular base part 1, to which two longitudinal side walls 2 and two end side walls 3 are connected via fold lines 4 and 5, respectively.
  • the side walls 2, 3 each consist of a first side wall strip 6, 7, to which a second side wall strip 10, 11 is articulated via a further folding line 8, 9 which is parallel to the folding line 4, but has a smaller length than the folding line 4.
  • the second side wall strips 10 and 11 together with the associated first side wall strips 6 and 7 serve to form a double side wall 2 in the central region.
  • the short edges 12 of the first side wall strips 7 of the end side walls 3 are followed by three-part approaches 13, which are used to form corner supports.
  • the three parts 14, 15, 16 of the extension 13 running parallel to the short edge 12 are separated from one another by fold lines.
  • the length of the first part 14 and third part 16, as seen from the short edge 12, is made somewhat shorter towards the adjacent longitudinal side wall 2 than the length of the central part 15.
  • the fold line 8 and 9 between the two side wall strips 6, 10 and 7, 11 extends centrally over the side walls 2, 3 to the area in which a corner support is formed by the extension 13. At the ends of the side walls 2, 3 pointing towards the corner, they have an upper edge 17, 18, to which second side wall strips 10, 11 no longer connect. In the area of these edges 17, 18, the respective side wall 2, 3 is therefore formed only in one layer.
  • the upper edge 17, 18 lies further away from the associated fold line 4 or 5 between the longitudinal side wall 2 or end face wall 3 and bottom part 1 than the fold line 8 or 9 between the two side wall strips 6, 10 or 7, 11 of the side walls 2, 3rd
  • the upper edge 18 of the end wall strips 7 is designed as a fold line, via which a triangular connecting piece 19 is articulated to the end wall 3.
  • the connecting piece 19 is a right-angled triangle, the second catheter of which is designed as a second fold line 20, which is opposite the short edge 12 of the end wall strip 7 is slightly offset to the outside.
  • an adhesive flap 21 is connected to the connecting piece 19, the length of which is somewhat longer, namely approximately by the thickness of the cardboard material, than the height of the adjacent longitudinal side wall 2 in the region of the edge 17.
  • the offset of the second fold line 20 with respect to the short edge 12 of the front side wall 3 allows the corner support formed by the extension 13 to reach over through the connecting piece 19 and the adhesive flap 21 to fold down on the outside of the longitudinal side wall 2.
  • the width of the adhesive flap 21 is slightly larger than the width of the first part 14 of the extension 13 and can also be somewhat wider than the upper edge 17 of the longitudinal side wall 2.
  • Figure 1 illustrates that the connector 19 and the adhesive tab 21 do not protrude beyond the outer boundary of the rectangular piece of cardboard formed by the remaining blank parts, in particular by the double side walls 2, 3.
  • Connector 19 and adhesive tab 21 can therefore be formed when punching the blank from the same rectangular piece of cardboard that would be required without the provision of connector 19 and adhesive tab 21.
  • FIG. 2 shows the crate erected and glued from the blank from FIG. 1.
  • the tray consists of a base 1, longitudinal side walls 2 and end side walls 3.
  • corner supports 22 which are formed from the shoulders 13.
  • the side walls 2, 3 are double-walled by folding the second side wall strips 10 and 11 around the folding lines 8 and 9, which are now at the top.
  • the triangular corner supports 22 are formed.
  • the first part 14 comes flat against the long side wall 2 and the third part 16 flat against the front side wall 3 and is glued there.
  • the middle part 15 connects the two parts 14, 16 together as a diagonal.
  • the connecting piece 19 is folded down from the upper edge formed as the first fold line 18 of the end face 3 formed in this area so that it covers the upper side of the corner support 22 formed by the parts 14, 15, 16.
  • the second fold line 20 of the connecting piece 19 is now due to the displacement of the second fold line 20 with respect to the short edge 12 of the end face 3 to the outside somewhat outside of the adjacent longitudinal side wall 2, preferably by exactly the material thickness.
  • the adhesive tab 21 can be bent downward and glued flat to the outside of the longitudinal side wall 2.
  • the adhesive flap 21 is so long that its lower edge is flush with the lower edge of the longitudinal side wall 2. In the event of a pressure (compression pressure) acting on the corner support 22 from above, the adhesive tab 21 thus reinforces the corner support 22.
  • Figure 3 illustrates the structure of the tray according to the invention in the corner area. Shown is a corner of an upright, already glued to the side walls 2 and 3 and to the corner support 22.
  • the connecting piece 19 and the adhesive flap 21 have not yet been bent into their final position and are shown outwardly bent around the first fold line 18 for clarity.
  • the corner support 22 is transverse by winding up the parts 14, 15 and 16 of the extension 13, the first part 14 being glued flat to the adjacent longitudinal side wall 2 and the third part 16 being glued flat to the end wall 3.
  • the triangle formed by the corner support 22 is covered from above by the connector 19 folded around the first fold line 18, the second fold line 20 coming to lie somewhat outside the crate and allowing the glue flap 21 to be folded down, the glue flap 21 being flat is glued to the outside of the longitudinal side wall 2.
