Definitions

  • the invention relates to a plastic crate or container, comprising a bottom and crate walls, and in at least one crate wall an opening which is bounded at the top side by a grip, which is composed of a crate wall part which passes downwards via a flexible connecting part into a flap which is intended for bending upwards and lying against said crate wall part, while a wall weakening is provided in the connecting part parallel to the bending axis.
  • Such a crate is known from DE-A-3 927 767.
  • a grip is formed by flapping up a flap which is connected by means of a film hinge to a crate wall part lying above it and making it engage in said crate wall part.
  • a sturdy grip can be obtained by using a flap-up part, despite the low wall thicknesses of the crate wall part and the flap.
  • This DE-U-89 12 048.5 also describes an embodiment of a grip, in which the top side of the flap is bent downwards, the film hinge lies at the top side of the crate, and the bottom side of the grip is rounded.
  • the carrying comfort is also reduced, due to the fact that in the rounded bottom side, around which the hand falls when the crate is being lifted, at least one injection moulding seam is present for manufacturing reasons.
  • the object of the present invention is then to provide a crate with a grip which offers increased carrying comfort.
  • a plastic crate of the type described in the preamble in which the connecting part is weakened by means of a number of grooves which run parallel to the bending axis of said connecting part and are spaced a short distance apart.
  • This allows a uniform deformation of the connecting part during bending, so that a grip without sharp corners can be produced, which provides increased carrying comfort.
  • the deformation of the connecting part can be carried out with heating, or cold if the connecting part is sufficiently thin at the position of the weakened points.
  • the grooves are of such size that after bending over the flap the groove edges rest essentially against each other. In this way the connecting part retains its shape after bending. It is conceivable here to use V-shaped grooves and to make the sum of the angles of these grooves equal to the angle through which the flap is to be bent for it to rest against the crate wall part.
  • the connecting part and the flap fall essentially inside the two boundary faces of the crate wall containing the grip, which faces run essentially parallel to the crate wall.
  • the injection mould required for such an embodiment can be simple in shape and does not need to have any additional moving mould side parts which, due to the fact that they cannot be provided with cooling channels, lengthen the cycle times.
  • tongues and/or recesses are provided on the flap and the crate wall part, in order to fix the flap relative to the crate wall part after bending over, by forming a snap closure.
  • faces which lie against each other after the flap is bent over are provided on the flap and the crate wall part. These faces can be glued to each other or heat-sealed, so that the flap is fixed relative to the crate wall part.
  • thickened parts are provided on the crate wall part and/or the flap, just fitting between the crate wall part, the connecting part and the upward bent flap. These thickened parts give the grip additional stiffness, and thereby reduce the deformation occurring during lifting of the crate.
  • a particularly advantageous embodiment is produced if parts of the crate are made double-walled, and the double-walled crate parts are of virtually the same thickness as the grip with upward bent flap. In this way the grip can form an uninterrupted whole with the crate walls, without projecting.
  • an injection mould for producing a crate according to the invention comprising at least an inner mould part and an outer mould part, in which each of these mould parts is unsplit around the cavity part enclosed by said mould parts for forming the connecting part.
  • Fig. 1 shows a crate 4 with a bottom, in which partitions 5 for placing bottles are disposed, and crate walls 6, 7, 8, 9 and two openings which are bounded at the top side by grips 10, 11, the design of which is shown enlarged in Fig. 2.
  • Fig. 2 shows a part of this crate with a grip, which is composed of a crate wall part 12 which passes downwards via a connecting part 13 into a flap 14.
  • Parallel grooves 15 are provided as a weakening in the connecting part 13.
  • Reinforcement ribs 16 and fixing tongues 17 are provided on the crate wall part 12.
  • Fig. 3 is a cross-section of the same crate part, in which the crate below the grip has a double wall 18, which is also bounded more or less by the same face at the inside of the crate as the flap 14, connecting part 13 and crate wall 12. It can be seen that the connecting part and the flap fall essentially inside the two boundary faces of the crate wall running essentially parallel to the crate wall.
  • Fig. 4 shows a view of a part of a crate, which differs from the crate of Figs. 1, 2 and 3 through the fact that different fixing means are used.
  • top edge 21 On the crate wall 20 there is a top edge 21 with tongues 22, which top edge 21 projects laterally and covers the flap 23 when the latter is bent upwards.
  • an edge 24 is provided on the flap 23 and can grip behind the tongues 22 and fix the flap 23 in the bent upward position.
  • Fig. 6 shows the same cross-section as that in Fig. 5, but this time with the flap 23 in the bent upward and fixed position.
  • the ribs 25 in this case just fit between the crate wall part 20 and the flap 23.
  • the connecting part is weakened by means of a number of grooves running parallel to the bending axis of this connecting part and spaced a short distance apart, as can be seen in the figures, so that a comfortable, rounded grip can be obtained.
  • the injection mould (not shown) for producing a crate according to the invention comprices, as usual, an inner mould part and an outer mould part, said mould parts enclosing a mould cavity.
  • each of the mould parts is unsplit around the cavity part for forming the connecting part 13.
