(17) FIGS. 1 to 5 of the drawings show a container 10 comprising a rectangular base 12 and four upstanding side walls 14 extending upwardly from the base 12. The base 12 has an upper face 16 and a lower face 18, and defines a recess 20 extending upwardly from the lower face 18.

(18) A reinforcing mesh formation 22 is provided within the recess 20. The mesh formation 22 is in the form of a rib arrangement comprising a plurality of ribs that extend across the recess 20. The plurality of ribs comprises a plurality of substantially parallel first ribs 24 and a plurality of substantially parallel second ribs 26.

(19) The first ribs 24 extend crosswise relative to the second ribs 26, substantially at right angles thereto. The mesh formation 22 is, therefore, in the form of a plurality of rectangles 28 formed by the intersecting first and second ribs 24, 26.

(20) The base 12 comprises a rim portion 30 extending from the side walls 14 to the recess 20. The rim portion 30 extends around the recess 20 and occupies a region between the upstanding side walls 14 and the recess 20. In the embodiment shown in the drawings, the rim portion 30 occupies substantially 35% of the area of the base, and the recess 20 occupies substantially 65% of the area of the base.

(21) The base 12 has an upwardly extending protrusion 32 that defines the recess 20. The protrusion 32 extends upwardly from the rim portion 30.

(22) The recess 20 has an edge portion 34 that slopes upwardly from the rim portion 30. The recess also has a substantially planar main portion 36 within the edge portion 34. The edge portion 34 extends wholly around the main portion 36. Each of the first and second ribs 24, 26 extends across the main portion 36 diagonally relative to the side walls 14, and terminates at the edge portion 34.

(23) As can be seen from FIG. 3, the first and second ribs 24, 26 are of different lengths. The majority of the first and second ribs 24, 26 extend from the edge portion 34 across the main portion 36. However, the shorter of the first and second ribs 24, 26, at the corners of the recess 20, do not extend beyond the edge portion 34.

(24) The rim portion 30 has a lower face 38. Each of the first and second ribs 24, 26 has a lower edge 40 that is coplanar with the lower face 38. Thus, the lower edges 40 and the lower face 38 provide a surface to engage the ground when the container 10 is disposed thereon.

(25) The rim portion 30 has an upper face 42. The protrusion 32 has an upper surface 44 and a lower surface 46. The lower surface 46 of the protrusion 32 is arranged above the upper face 38 of the rim portion 30. Each of the first and second ribs 24, 26 has an upper edge 48 attached to the lower surface 46 of the protrusion.

(26) There is thus described a container 10 having a reinforcing mesh formation 22 provided in a recess 20 in the base 12. The mesh formation 22 strengthens the base 12 to prevent it from sagging without any need to increase the thickness, and weight, of the base 12. The mesh formation 22 and the rim portion 20 mean that the container 10 retains its stiffness over the entirety of the base 12 while maintaining the impact resistance of the rim portion and corner regions of prior art containers.

(27) The provision of the mesh formation 22 provides an advantage in the embodiment described herein that the overall weight of the container 10 is no greater than the weight of prior art similar containers, but there is an improvement in the strength and rigidity of the container.

(28) The provision of the rim portion 30 and the mesh formation 22 provides a further advantage in the embodiment described herein of maintaining the stiffness of the base and reducing the risk of damaging the corners or edges of the base 12 in the event that the container 10 is dropped. Tests have shown that the container 10 is less likely to be damaged than a similar container with a 20% to 60% thicker base and no recess or mesh formation on the base.

(29) Various modifications can be made without departing from the scope of the invention.

(30) FIGS. 6 to 11 of the drawings show a lid 110. The lid 110 is intended to be part of a container 1100 (see FIGS. 12 and 13). The container 1100 may be the same as the container 10 described above, or may be a different container.

(31) The lid 110 comprises a cover portion 112 for covering an internal space defined by a body 1102 of the container 1100. As shown in FIG. 12, the container 1100 comprises two lids respectively designated 110 and 110A. The lid 110A is identical to the lid 110.

(32) The body comprises a base 1104, and further includes a pair of upstanding opposite first walls in the form of side walls 1106 and a pair of opposite upstanding second walls in the form of end walls 1108 extending between the side walls 1106. The side walls 1106 and the end walls 1108 extend upwardly from the base 1104.

(33) The lid 110 further includes a rim arrangement 111 extending around the cover portion 112. The rim arrangement 111 comprises a connecting region 114 for connecting the lid 110 to the body 1102 of the container 1100. The connecting region 114 comprises a plurality of hinge portions 116 which connect to corresponding further hinge portions 1110 on the side walls 1106. The hinged connection of the lid 110 to the body 1102 allows the lid 110 to move pivotally between open and closed conditions.

(34) The cover portion 112 has a first surface 118 in the form of an inner surface which faces the internal space defined by the body 1102 of the container 1100 when the lid 110 is in the closed condition. The cover portion 112 also has a second surface 120 opposite the first surface 118. The second surface 120 is in the form of an outer surface, which faces outwardly when the lid 110 is in the closed condition.

(35) The rim arrangement 111 further includes opposite holding formations 122 for holding a securing member, in the form of a strap 124 (shown in broken lines in FIG. 7), across the lid 110. Each holding formation 122 comprises a guide formation 126.

(36) The guide formation 126 has a convexity 126A which faces outwardly. The guide formation 126 further includes a planar member 126B extending tangentially from the convexity 126A.

(37) The convexity 126A has an end profile in the shape of arc extending over substantially a quarter of a circle. The planar member 126B has a distal edge 127 spaced from the convexity 126A.

(38) The holding formation 122 is shown in more detail in FIG. 11. The convexity 126 extends from the cover portion 112 and is arranged so that the cover portion 112 is tangential to the convexity 126.

(39) Each holding formation 122 further includes a plurality of retaining members 128 extending outwardly from the guide formation 126. Each retaining member 128 has first and second edges 130, 132 that meet at an apex 134. The first edge 130 is coplanar with the second surface 120 of the cover portion 112. The second edge 132 of each retaining member 128 extends to the distal edge 127 of the planar member 126B.

(40) Each holding formation 122 further includes an inwardly facing concavity 136 having an internal surface that has a curvature that corresponds to the curvature of the convexity 126. When the lid 110 is in the closed condition, the concavity 136 engages the body 1102 of the container 1100. FIG. 14 shows a top edge 1110 of one of the end walls 1108. The top edge 1110 defines an elongate recess 1112 to receive one of the holding formations 122 of each lid 110. The recess 1112 has a pair of opposed steps 1114 and an elongate recessed portion 1116 extending between the steps 1114. The holding formation 122 is received in the recess 1112 between the opposed steps.

(41) When the holding formations 122 on one side of each lid 110 are received in the recess 1112, the elongate recessed portion 1112 is received in the concavities 136 of the holding formations 122.

(42) In use, the lid 110 can be secured in the closed, condition by the strap 124 secured around the container 1100. The strap 124 extends between adjacent retaining members 128 on each of the holding formations 122 and is tightened around the container 1100. The retaining members 128 prevent the strap 124 from being slid 110 off the lid 110, thereby helping to ensure that the lid 110 remains closed by the strap 124 and articles inside the container 1100 cannot be stolen.

(43) The rim arrangement 111 also includes an interlocking region 138 opposite the connecting portion. The interlocking region 138 is provided to interlock with a similar further lid 110A connected to the body opposite the lid 110.

(44) The interlocking region 138 comprises a plurality of alternating recesses 138A and projections 138B. As shown in FIG. 12, when the lid 110 and the further lid 110A are in their closed conditions, the recesses 138A of the lid 110 receive the projections 138B of the similar further lid 110A, and the projections 138B of the lid 110 are received by the recesses 138A of the further lid 110A. This secures the lids 110, 110A to one another in their closed conditions.

(45) Various modifications can be made without departing from the scope of the invention. For example, a different number of the retaining members 128 of each holding formation 122 of the lid 110 could be provided.

(46) FIG. 15 shows a second embodiment of the lid 110, which comprises many of the features of the lid 110 shown in FIGS. 6 to 14. These features are designated in FIG. 15 with the same reference numerals as the corresponding features in FIGS. 6 to 14.

(47) The lid 110 shown in FIG. 15 differs from the lid 110 shown in FIGS. 6 to 14, in that the interlocking region 138 of lid 110 shown in FIG. 15 has recesses 138A and projections 38B that are smaller than the recesses 138A and the projections 138B.

(48) In addition, the retaining formations 128 extend only around the convexity and do not extend to the distal edge 127 of the planar member 126B.
