Definitions

  • the invention relates to a nestable crate comprising a base, side walls standing transversely of the base and having a free upper edge, at least a first stacking member which is arranged close to the base and which can support on a second stacking member when the crates are stacked, which second member is arranged close to the upper edge in the line of the first stacking member and is provided with a support means for stackably supporting crates in a stacked state and nestably receiving crates in a nested state.
  • Such a device is known from NL-1006349.
  • the known crates are stackable in that a stacking member of a first crate supports on a second crate.
  • the crates can be nested when they are held upside down because the force of gravity carries a hinged support part from a stacking state to a nesting state.
  • the hinge is arranged parallel to the side wall.
  • the hinged flap pivots about the pivot axis and therefore in a plane perpendicular to the side wall.
  • the pivot shaft arranged parallel to the side wall is very vulnerable since it must take a very thin form so as not to make the crate wider in breadth direction.
  • the invention has for its object to provide a nestable crate which is less vulnerable.
  • This object is achieved according to the invention with a nestable crate wherein the support means is movable substantially parallel to the plane of the side wall. More space hereby becomes available, allowing the support means to be embodied in a stronger, for instance larger, form.
  • the support means is for instance slidable substantially parallel to the plane of the side wall.
  • the support means is preferably movable, in a placed-upright position of the crate, under the influence of gravity to the stacked state and, when the crate is turned over, movable under the influence of gravity to the nested state.
  • the choice between stacking or nesting of the crates can hereby be readily determined for the user. There is only one significant condition for stacking of the crates, viz. that the filling side of the crate faces upward. This is a position of the crate which is naturally adhered to, since otherwise the load would fall out of the crates. For nesting of the crates it is only necessary to ensure that the filling side of the crate is directed downward. Due to the action of gravity the support means hereby drops into the position in which the crate can be nested.
  • the support means preferably comprises a hinged flap pivotable about a pivot axis directed substantially perpendicularly of the side wall.
  • the nestable crate comprises a stacking part comprising a wall portion which is offset transversely of the plane of the side wall and in which the first and second stacking members are received.
  • a stacking part which is continuous when crates are stacked and which provides the necessary strength.
  • the stacking parts lie mutually in line when stacked, so that a stable column of crates is formed.
  • the stacking part is preferably situated on an external surface of the side wall.
  • the largest possible smooth inner side of the crate is hereby formed.
  • the stacking part preferably comprises a receiving space for a stacking part of a second nested crate.
  • the stacking parts of respective crates can hereby be nested in each other.
  • the nestable crate preferably comprises a rigid material and the support means comprises relatively heavy material, in order to obtain a readily movable action as a result of gravity.
  • a crate according to the invention can also be manufactured in a more efficient manner.
  • the crate can be injection moulded together with the hinged flaps substantially in a single run.
  • Figure 1a shows nestable crate 1 provided with a base 2 and four side walls 3-6 standing transversely of base 2.
  • Nestable crate 1 is manufactured by injection moulding with a curable material in a mould.
  • Crate 1 can be used as a vegetable container, for instance for tomatoes.
  • Support part 8-11 are connected to the outer surfaces of side walls 3,5.
  • Support parts 8-11 form outwardly offset wall parts placed symmetrically close to the corners of crate 1.
  • a second stacking member 13 is arranged close to the upper edge 7 of nestable crate 1.
  • This stacking member 13 is arranged partly in the upper edge and defines a profile provided with recess 14 in which a support means (not shown in figure 1) can be received.
  • a support means not shown in figure 1
  • the first stacking member 12 can be received as according to arrow 16 in the receiving space 15 defined by stacking part 8, whereby the crates are mutually nestable. In this open position the opening to receiving space 15 is not blocked.
  • a support means is situated in the space between upper edge 7 and receiving space 15.
  • This support means then blocks the passage according to arrow 16 through the second stacking member 13 to the receiving space 15 below this stacking member 13.
  • the blocking then also provides the support of the first stacking member 12 arranged as according to arrow 16 when this is arranged in or on second stacking member 13 as according to arrow 16.
  • the first stacking member 12 can support on the support means of the second stacking member 13.
  • the support means is moved parallel to side surface 5 out of recess 14 as according to arrow 17, so that stacking parts 8-11 cannot nest. The action of the support means will be further described hereinbelow.
  • a recess 18 running parallel to stacking part 10, which enables nesting of stacking parts 8-11. Without recess 18 the stacking parts could not be firmly connected to the side walls of the crate.
  • Figure 4a shows crate 20 held in an upside down position, wherein base 21 lies at the top and upper edge 22 at the bottom. For the user it will always be apparent that the crate must not be filled in this position.
  • first stacking member 23 Shown are a first stacking member 23 and a second stacking member 24 which form part of support part 25, which lies substantially in a plane parallel to the surface of side wall 26.
  • the second supporting member comprises two hinged flaps 27,28, provided with studs 29,30 forming the pivot axis of hinged flaps 27,28.
  • the studs are held in place by a lip of the crate.
  • Other receiving means can also be arranged in the crate for receiving the studs.
  • the pivot axis is perpendicular to the side wall, whereby the hinged flaps can pivot according to arrows 31,37. This motion takes place in the plane parallel to the surface of side wall 26.
  • the size of the hinged flaps is largely determined by the size of the space 35,36 in which hinged flaps 27,28 are received.
  • a stacking part 25 can be received in receiving space 32 when the stacking part 38 of a second crate has been moved with the first stacking member first into receiving space 32 as according to arrow 33. Hinged flaps 27,28 are moved such that receiving space 32 is accessible.
  • Figure 4b shows the upright crate 21 situated in the stackable position, with hinged flaps 28,27 in the stacking state, wherein arranging a stacking part 38 by means of a first stacking member as according to arrow 34 has the result that hinged flaps 28,27 will support the first stacking member, whereby the crates are stacked.
  • the stacking parts form a continuous column which gives the stacked or nested crates a great stability.
  • the hinged flaps 27,28 are manufactured, in contrast to the material from which the crate is manufactured (for instance polypropylene), from relatively heavy material such as for instance metal or plastic with a high density, such as ABS.
  • relatively heavy material such as for instance metal or plastic with a high density, such as ABS.
  • the support means Under the influence of gravity the support means will move toward the stacked state in the placed-upright position of the crate and, when the crate is turned over, will move under the influence of gravity toward the nested state.
  • the hinged flaps 27,28 are received in receiving cavity 35,36 arranged on either side of receiving space 32. In the upright position the hinged flaps 27,28 move out of receiving cavity 35,36 into a situation wherein receiving space 32 is not accessible via arrow 34.
