Definitions

  • the present invention relates to a plastic crate according to the preamble of claim 1.
  • Such a crate is known from DE-A-38 23 650.
  • the lower edge of the handles is formed by a thick hollow part with a round cross section.
  • the cavity in this hollow part is an elongated straight channel.
  • the known crate has the disadvantage that the shape of the handle is still not optimal in order to lie easily in the hand.
  • the object of the invention is to provide a plastic crate with improved handles.
  • the channel-shaped cavity is curved it is possible to provide the crate with a handle, which has also a hollow part at its upper edge, so that the handle lies very easily in the hand and also has the required strength, whereas it is still possible to mould the handle in a technically and economically advantageous manner.
  • the crate shown in Fig. 1 comprises a bottom 1, two long vertical side walls 2 and 3, and two short vertical side walls 4 and 5.
  • the side walls of the crate are made double-walled.
  • the two long side walls 2 and 3 lying opposite each other are each provided at the top side with a handle 6, 7 respectively, which at the bottom side is bounded by a handle opening 8, 9 respectively.
  • the handles 6 and 7 are integral with the rest of the crate and are made partially hollow.
  • Fig. 2 the handle part with the handle 7 is shown on an enlarged scale, the hollow part being indicated by the reference numbers 11a and 11b.
  • the cavity in the hollow part 11a, 11b is in the form of an elongated channel 12a, 12b which is surrounded by wall parts 13a, 13b together forming an essentially closed wall.
  • the channel-shaped cavity 12a, 12b is U-shaped, and the wall parts 13a, 13b form, as it were, a U-shaped tube.
  • the channel-shaped cavity 12a, 12b has an essentially round cross-section.
  • the legs of the U run parallel to the bottom 1 of the crate, and the wall parts 13a and 13b of the U-shaped channel 12a, 12b form the top and bottom part of the handle 7.
  • a handle formed in this way lies well in the hand, so that great carrying comfort is achieved.
  • the wall parts 13a, 13b of the U-shaped channel 12 are connected to each other by a connecting wall part 14.
  • this wall part 14 lies on the outside of the crate, with the result that the handle 7 on the outside of the crate is smooth.
  • the handle 6 is designed in the same way as the handle 7.
  • side walls 4 and 5 of the crate can also be provided with a handle, like the handles 6 and 7.
  • the wall part 14' connecting the wall parts 13a, 13b can also be provided approximately in the longitudinal centre plane 15 of the handle.
  • the advantage of this is that the stress distribution in the handle is better.
  • the channel-shaped cavity 12a, 12b is the shape of a U.
  • the channel-shaped cavity can, however, be other shapes, for example the shape of a Z or an S.
  • a handle of a crate designed in the manner described above lies easily in the hand and can be formed in a technically and economically advantageous manner.
  • a method for forming a handle according to the invention is described in Applicant's Netherlands patent application No. 9002483 entitled: "Method and device for forming a cavity in a plastic injection-moulded product”.
  • the invention is described for a crate of a particular shape.
  • the invention is not, however, limited to such a crate, and can equally well be used for crates or trays of a different shape and different dimensions, provided with a framework or not.
