Definitions

  • the invention relates to a stackable packaging having corner-reinforcing members, comprising a box provided with a cardboard bottom as well as cardboard side and end panels, said end panels of the blank being provided with two four-sided posts for reinforcing the corners of the packaging in the erected condition of the packaging, and a bridge that is parallel to the bottom in the erected condition of the packaging and covers the corner-reinforcing members, said bridge of the blank being connected to two bridge strips that are fixed in the erected condition of the packaging to a side panel as well as to one side of the four sides of the corner-reinforcing member, while another side of each corner-reinforcing member is fixed to a related end panel, said bottom, panels, bridges and strips being connected to one another or separated from one another by foldlines.
  • Such packagings should be able to replace the familiar wooden tomato crates, provided they are made of a foldable material adapted to the three-days' stay within a so-called moist cold store with a through-flow cooling system.
  • a more or less obvious material comprises a water-repellent grey cardboard of a density of 900 g/m2 that is provided at both sides with a sheet of polyethylene ad 15 g/m2 in between layers of paper ad 40 g/m2. This material appears to fail to give the box of the above type adequate stability, which is illustrated by the fact that the end panels are not perpendicular to the bottom.
  • the packaging In applying the invention to packagings of about 38 x 29 x 14 cm, the usual dimensions for packaging roughly 6 kilograms of tomatoes, the packaging should have a compression resistance of at least 490 kg after having stayed for three days within a moist cold store with a through-flow cooling system. The above three days are connected with the weekend, and in this respect 'moist' implies a relative humidity level of around 90% at a temperature of ca. 13°C.
  • Packagings meeting the above-mentioned requirements do exist indeed, yet they can only be used in automatic folding machines which are only profitable when used at large market gardens.
  • the invention aims to provide a cardboard packaging which is both easy to erect manually and is suitable for packaging tomatoes and similar products, if made of a suitable material. According to the invention this aim is realized by the measure that the other two sides of the corner-reinforcing members are oversized, so that in the erected condition of the packaging they will be arranged by snap action substantially in between the sides of the corner-reinforcing members, which are connected to the end panels and the bridge strips.
  • the bridges are provided with apertures, through which locking cams arranged at the edge of the corner-reinforcing members facing away from the bottom can pass in the erected condition of the packaging, then it can be guaranteed that the contents of the box will be diminished as little as possible by those members. Besides, all sides of the corner-reinforcing members will be arranged at those sections of the packaging which are put under the maximum load.
  • the locking cams have an axis of symmetry that coincides with the foldline between the oversized sides of the corner-reinforcing members.
  • the cams are made rigid.
  • the recesses in at least the bridges are circular-segment-shaped and have semi-circular ends, those apertures would tear in the least possible way.
  • the represented blank comprises a bottom 1, which is connected to two side panels 4 via foldlines 2 and 3, as well as to two end panels 7 via foldlines 5 and 6.
  • Two foldlines 8 are provided in the side panels 4 at an angle of 45°, largely bounding triangular flaps 9 which are to be folded upwards through an angle of 180°, and a foldline 10 extending parallel to the foldlines 2 and 3 which forms the boundary of a side edge reinforcing strip 11 that is to be folded through 180° during the production, so that it will be arranged eventually at the inside of the packaging.
  • the members 8-11 which are of minor significance to the invention, and consequently they will not be discussed in this context.
  • End panel 7 is bounded by both foldline 6 and two vertical foldlines 12, 13, as well as one horizontal foldline 14.
  • the foldlines 12 and 13 of the blank are in line with the foldlines 2 and 3 of the bottom.
  • four sides 18-21 of the intended corner-reinforcing members are arranged which are connected to one another by foldlines 15-17.
  • a bridge 22 is arranged, the right boundary of which will be arranged adjacent to the vertical centre line of the bottom 1 after having been folded together with the end panel 7 along foldline 6 through 180°.
  • Bridge 22 also has two foldlines 23 and 24 which provide a pliable connection to two bridge strips 25 and 26, said bridge strips 25 eventually being arranged in between and fixed to, for example by means of an adhesive, the outer surface of side 18 and - after folding - to the inner surface of flap 9.
  • the oversized condition of the sides 19 and 20, the total of their widths in particular, in relation to an imaginary, diagonal joint line connecting the foldlines 15 and 17, enables the snap action and results in very rigid corner-reinforcing members in the final state of the box, said corner-reinforcing members being very well adapted, in particular, to resist forces which are mainly exerted horizontally and act on the corners of the box from the outside and being able to support a load of high-stacked packagings.
  • Each of the corner-reinforcing members 18-21 are provided with a locking cam 27 having a symmetry axis coinciding with the foldline 16 between the overdimensioned sides 19 and 20. In this way, the locking cams are more rigid than if they would have been just flat.
  • the bridges 22 are provided with apertures 28 which are arranged in the angular sections of the bridges which are bounded by the foldlines 14 and 23, 24.
  • the locking cams 27 project into or through said apertures. They project into them when their height only slightly exceeds the thickness of the bridge 22, and they project through them when they are only a little larger than about twice the thickness of the bridge. In the latter case, they are to be accomodated in corresponding apertures 29 in the four corners of the bottom 1 of a packaging put on top of the bridges.
  • the apertures 28 and 29 may be shaped like a slit or a triangle, yet a circular-segment shape with semi-circular ends is preferred, as that shape has the least chance of tearing.
  • the above-described packaging can be produced by means of automatic machines. After punching the blank and applying the foldlines into it, at first the sides 21 are fixed (adhered) to end panels 7, so that they will be adjacent to the sides 18. After that the side-panel-reinforcing strips 11 are folded along foldline 10 through 180°, abutting against the upper surface of the side panels 4, and fixed (adhered) to it, and the flaps 9 are folded along foldlines 8 through 180° so that they abut against the lower surface of the side panels 4, and subsequently the members 4, 9 and 11 are folded together along foldlines 2 and 3 through 180° so as to abut against the upper surface of the bottom 1.
  • the bridges 22 are folded upwards along the foldlines 14 through 90°, after which the bridge strips 25 and 26 are folded along the foldlines 23 and 24 in such a way that, after the folding of the members 7, 18-22 through 180°, said bridge strips 25 and 26 will be arranged between the sides 18 and the flaps 9 and fixed (adhered) to them.
  • the bridges 22 are folded along foldlines 30 extending radially through the apertures 28 at an angle of 45°.
  • corner-reinforcing members could also be formed after the erection of the side panels 4 yet prior to folding the end panels 7.
  • foldlines 8 of the illustrated example near the intended lower corners, indicated by 31, as well as to the foldlines 16, indicated by the bold line sections 32.
  • apertures 33 which are known per se, are applied in order to allow fingers to grip when handling the packagings.
