  • the cord 55 can then be passed through both that hole 50 and a corresponding hole on the other opposing tab 45, thereby connecting the tabs 45.
  • the cord 55 is looped around and passes through a second hole 50 on the opposite tab 45, before passing through a corresponding second hole on the first tab 45. It can then be secured, again by tying a knot that is has a greater cross section than a hole 50, for example.
  • the cord can form a handle, as mentioned above.

  • FIG. 2 illustrates the exemplary container 1 with the closure mechanism 10 in a closed configuration.
  • the tabs 45 may be urged together by a user applying tension to the cord (handle) 55 to cause the outer flaps 40 to hinge inwardly about the straight upper edges 20 of the flat faces 15, thereby being brought together, for example.
  • the inner flaps 35 are pushed inwards by the closure of the outer flaps 40, causing them to fold inwardly beneath the outer flaps 40.
  • the downwardly curved edges 30 of the curved sides 25 of the container 1 promotes the inward folding of the inner flaps 35, and may additionally cause the inner flaps 35 to curve when closed, which can help to retain (or secure) the inner flaps 35 in their closed (i.e. "folded") position.
  • the inner flaps 35 may at least partially overlap (i.e. one of the inner flaps 35 at least partially overlaps the other of the inner flaps 35), thereby substantially closing the aperture.
  • Figure 3 illustrates the exemplary container 1 with the closure mechanism 10 in an open configuration allowing access to the interior compartment 100 of the container 1 via the aperture 65.
  • the inner flaps 35 bow outwardly in a substantially similar fashion as the curved faces 25. It is the action of closing the outer flaps 40 by bringing the tabs 45 together that pushes the inner flaps 35 inwardly and downwards, causing them to fold inwards and close off the aperture 65 to the interior compartment 100.
  • the handle formed by the cord 55 is clearly visible.
  • the cord 55 is secured to one of the tabs 45 by means of knots 70 that are larger than the holes 50 in the tabs 45.
  • the cord 55 passes through the holes 50 to which it is secured and through corresponding holes 50 of the other tab 45.
  • the tabs 45 can thereby be drawn together such that they are adjacent to and/or substantially abut each other by drawing (i.e. pulling) the cord 55, preferably in a substantially vertical direction away from the tabs 45, to urge the tabs 45 together.
  • Figure 4 illustrates a net 200 for the exemplary container 1 shown in unassembled form.
  • the net (or “blank”) comprises two flat faces 15 and two curved faces 25 that define the interior compartment 100,two inner flaps 35, and two outer flaps 40 provided at the upper ends of the curved faces 25 and flat faces 15, respectively.
  • the tabs 45 can be seen extending from the top of the outer flaps 40, and may optionally be provided with reinforcing tabs (not shown), which can be folded behind the tabs 45 when in use in order to provide additional support and strengthening, particularly to the holes 50.
  • the base is formed by base tabs (or "portions") 75, which extend from the bottom ends of the flat faces 15 and the curved faces 25.
  • the base tabs 75 are folded and interlocked during assembly to create a base for the container 1 . While the base tabs 75 shown in this example comprise a substantially rectangular tab, a substantially rhomboid tab and two substantially triangular tabs, the skilled person will recognise that this is simply an exemplary arrangement and other base closures are possible. Interlocking bases such as this are commonly known and therefore no further explanation of the base is necessary here.
  • a 'joining' tab 80 extends from a free (i.e.
  • edge 85 one of the curved faces in order to facilitate the assembly of the net into the container 1 defining the interior compartment 100, preferably using an adhesive or similar means.
  • the joining tab 80 could equally extend from any open edge of one the faces at either end of the net.
  • the inner flaps 35 are in this example in the form of a curved trapezoid-like quadrilateral, such that the sides taper inwardly as they extend away from the flat faces.
  • the outer flaps 40 are substantially rectangular.
  • the net can be pre-scored for ease of assembly. Pre-scored lines are indicted in Figure 4 by the dashed lines.
  • the curved edges 30 can be pre-scored and/or perforated in order to allow the inner flaps 35 to be folded more easily.
  • the other edges in the net can be pre-scored for ease of assembly and use.
  • the curved faces 25 can also be pre-scored 95 to promote them bowing outwards when the container 1 is assembled.
  • the pre-scored lines 95 on the curved faces 30 are generally proximal to the vertical edges 90 of the curved faces 30 and are arranged to intersect the curved edges 30.
  • each curved face 30 has two pre-scored lines 95 proximal to each vertical edge 90, though other embodiments may have a different number.
  • the pre-scored lines 95 on the curved faces 25 are shown spaced closely together at the bottom end of the curved face 25 and diverge as they approach the upper end (i.e. the curved edge 30) of the curved face 25 to promote increased bowing of the curved face 25 towards the curved edge 30.
  • a handle may be formed by a single cord 55 passing through a single hole 50 on each of the tabs 45. It can be secured by tying a knot 70 at each end of the cord that has a larger cross sectional area than the hole(s) 50 through which it passes.
  • the tabs 45 can be pulled together by applying a tension to the cord 55.
  • additional cords 55 in a substantially similar arrangement can be provided such that the tabs 45 have one or more cords passing through them via holes 50.
  • one (or both) of the tabs 45 may comprise a cut out (not shown) that forms a hand grip.
  • the tabs 45 may each comprise an integral handle that extends from the top of each tab 45.
  • the handle may be formed as part of one of the tabs 45, with a slot (not shown) being provided in the other tab 45 through which the handle can pass and hence urge the two outer flaps 40 towards one another.
  • closure mechanism 10 does not need to seal the aperture 65 completely (e.g. air-tight) to perform its intended function, nor do the outer flaps 40 need to be brought completely together to cause the inner flaps 35 to close off the interior compartment 100.
  • the action of bringing the outer flaps 40 towards each other (without necessarily coming into full contact) should still provide the effect of causing the inner flaps 35 to fold inwardly and thereby substantially cover the aperture 65 of the container 1 to close off the interior compartment 100.
