When the first and second lids are in their closed positions, the projecting portions of each of the first and second lids may extend across the free edge of the other of the first and second lids.
When the first and second lids are in the closed positions, the rib formations of the first lid may overlap the lids of the second lid. In this position, each rib formation of the first lid may extend parallel to, and alongside, a corresponding rib formation of the second lid to provide a line of support that extends across the lid arrangement 2s from the hinged edge of the first lid to the hinged edge of the second lid.
The rib formations may comprise strengthening ribs.
Embodiments of the invention will now be described by way of example only, with reference to the accompanying drawings, in which:
Two of the side walls 16 arranged opposite each other are provided with respective hinge arrangements 17 to allow the lid arrangements 20 to be pivotally attached thereto.
The lid arrangements 20 comprise lids 22 that are pivotally movable between an open position shown in
Each of the lid arrangements 20 also includes first and second hinge pins 24 to pivotally attach the lid 22 to a respective one of the hinge arrangements 17 of the container 12.
Each lid 22 has opposite first and second side edges 23A, 23B and a hinge portion 25 extending between the side edges 23A, 23B. The hinge portion 25 has a central region 28 and a plurality of hinge members 26 through which the hinge pins 24 extend.
A plurality of first hinge members 26 extend from the central region 28 to the first side edge 23A. The first hinge pin 24 extends through the first hinge members 26. A plurality of second hinge members 26 extend from the central region 28 to the second side edge 23B. The second hinge pin 24 extends through the second hinge members 26.
When the lids 22 are arranged on the container 12, the first and second hinge members 26 on each lid 22 are aligned with the hinge elements 18 on the respective upstanding walls 16. This allows the hinge pins 24 to extend through the hinge members 26 and the hinge elements 18, to provide a hinge attaching the lids 22 to the upstanding walls 16.
Each hinge member 26 has a pivot element 30 at each of its opposite ends through which the hinge pin 24 extends to allow the lid 22 to pivot from between its open and closed positions.
Each of the pivot elements 30 comprises a web portion 32 extending across the end of the hinge member 26, the web portion 32 defining an aperture 34 through which the hinge pin 24 extends.
The hinge portions 25 of each lid 22 further include first and second cover members 36 within the central region 28. The cover members 36 extend over one end of the respective first and second hinge pins 24.
Each cover member 36 comprises a shroud 38 defining an opening 40 to allow insertion and removal of the hinge pins 24 when the lids 22 are in their open positions. Each cover member 36 has one of the aforesaid pivot elements 30 at each end thereof.
Referring to
The end stop member 48 is in the form of a flange. A pointed tip 50 is provided at the opposite end of the elongate member 46.
Each cover member 36 defines a receiving space 44 in which the end stop member 48 is received. The receiving space 44 has an internal sloping surface 42 to facilitate insertion and removal of the hinge pin 24 through the opening 40. The opening 40 is arranged so that, when the lid 22 is in the closed condition, the opening 40 is closed by an upper edge of the wall 16, thereby preventing removal of the hinge pin 24 through the opening 40.
The hinge pins 24 are inserted through the hinge elements 18 and the hinge members 26 via the cover members 36 when the lids 22 are in their open positions. The sloping surfaces 42 act as guide surfaces to guide the hinge pins 24 through the hinge members 26 and hinge elements 18.
When each hinge pin 24 is inserted into the hinge members 26 and hinge elements 18, the end stop member 48 is received in the receiving space 44 defined by the cover member 36. The end stop members 48 are wider than the aperture 34 in the pivot portion of the cover member 36.
Thus, the hinge pins 24 cannot be removed by pulling them at the tip 50 through the hinge members 26 and the hinge elements 18. The only way to remove the hinge pins 24 is by pulling the end stop members 48 through the openings 40 defined by the cover members 36
When the lids 22 are in their closed position, the shroud 38 extends over the end stop member 48 thereby preventing access to the end stop member 48. Thus, when the lids 22 are secured in their closed position, e.g. by a strap wrapped around the container 12 arrangement, access to the end stop member 48 is not possible, thereby preventing unauthorised removal of the hinge pins 24.
The main part 122 of each of the first and second lids 22, 22A also has a free edge 126 opposite the hinged edge 124. The main part 122 has a lower face 128 and an upper face 130.
Referring to
The strengthening ribs 132 extend at an angle of between 82° and 87° from the hinged edge 124. A typical angle is substantially 85°. Adjacent strengthening ribs 132 are slanted in opposite directions across the main part 122.
Adjacent strengthening ribs 132 of the first lid 22 define therebetween a plurality of first recesses 134 in the upper face 130. The first recesses 134 extend inwardly from the free edge 126 of the first lid 22 across the main part 122.
Similarly, adjacent strengthening ribs 132 of the second lid 22A define therebetween a plurality of second recesses 136. The second recesses 136 extend from the free edge 126 of the second lid 22A across the main part 122.
Adjacent strengthening ribs 132 of the first lid 22 provide a plurality of first projecting portions 138 extending outwardly from the free edge 126 of the first lid 22. Adjacent strengthening ribs 132 of the second lid 22A provide a plurality of second projecting portions 140 at the free edge 126 of the second lid 22A. The projecting portions extend outwardly beyond the free edge 126 of the first and second lids 22, 22A.
As can be seen from
Each of the first and second lids 22, 22A is pivotally movable about the hinge members 26 from an open position of each of the first and second lids 22, 22A to a closed position of each of the first and second lids 22, 22A.
When the first and second lids 22, 22A are in their closed positions, the first projecting portions 138 of the first lid 22 are received in the second recesses 136 of the second lid 22A, and the second projecting portions 140 of the second lid 22A are received in the first recesses 134 of the first lid 22, as shown in
Set out below is a description with reference to
In
The strengthening rib 132 of the first lid 22 extends parallel to the strengthening rib 132A of the second lid 22A. In the region of the first projecting portion 138, the strengthening rib 132 lies alongside the strengthening rib 132A. In the arrangement shown in
In the embodiment shown, the line of support S extends along both of the strengthening ribs 132, 132A and helps to prevent the lid 22, 22A from collapsing inwards. The creation of a line of support along at each of the strengthening ribs 132, 132A when the lids 22, 22A are in their closed positions. Thus, a plurality of lines of support S are created along both lids 22, 22A, thereby increasing the strength of the lids 22, 22A over lids of prior art containers.
Another feature of the lids 22, 22A is that the strengthening ribs 132 providing the first and second projecting portions 138, 140 define further recesses 142 extending inwardly from the hinged edge 124 of each of the lids 22, 22A. The strengthening ribs 132 defining the further recesses are slanted towards each other so that the further recesses 142 are wider than the projecting portions 138, 140.
The purpose of the further recesses 142 is to reduce the amount of space occupied by the containers 10 when they are nested within one another.
Two nesting containers, namely a lower container 10, and an upper container 10A, are shown in
As can be seen from
In the open positions of the lids 22, 22A shown in
The second projecting portions 140 of the lids 22A of the upper container 10A are received in the further recesses 142 defined by the lid 22A of the lower container 10, but this is not visible in the drawings.
The receiving of the projecting portions 138 and 140 in the further recesses 142 has the effect, as shown in
There is thus described a lid arrangement defining first and second recesses 136, 134 and first and second projecting portions 138, 140 that increase the strength of the lids 22, 22A when the lids are in their closed positions, and which, by virtue of the further recesses 142 allows the containers to be nested occupying minimal space.
Various modifications can be made without departing from the scope of the invention.
