Abstract
Abstract Boxes e.g. for fruit and vegetables are described which consist of a base and sidewalls folded up from the base. The ends of the sidewalls are held in position relative to one another and relative to the base of the box by means of a number of corner posts, e.g. four for a rectangular box. Each corner post is produced from an extruded section and can simply be slid on to the two adjacent ends of sidewalls when they are held substantially in the upright position. Means are provided to stop lateral movement of one corner post relative to the one below it when two such boxes are stacked vertically aligned. Such means may comprise shaping on the end of each corner post or intermediate stacking pegs which engage e.g. the top of one corner post and the bottom of the vertically adjacent next box.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
231 words
A box having a base and sidewalls folded up from the base, the sidewalls being held at their ends to form the corners of the box by extruded section corner posts, each corner post including a plurality of elongate channels open at both ends to enable the post to be slid axially on to the ends of adjacent sidewalls to hold the walls together at the corner of the box and in planes substantially perpendicular to the base, and including means comprising a plurality of stacking pegs each having a first and a second extremity enabling one box to be stacked on top of a like box with the two corner posts at each corner of the stack of two boxes so formed being vertically aligned, each said corner post at its top including means for engagement with a first extremity of a stacking peg, said base including adjacent a plurality of its corners means for engagement with a second extremity of a stacking peg, and each stacking peg having an offset configuration whereby each peg is engageable via the first extremity thereof with said engagement means at the top of a corner post and via the second extremity thereof with said engagement means in the base of a like box stacked immediately above, and the two boxes so stacked are positively prevented from moving laterally with respect to each other.
Claim 2
Dependent Claim
231 words
A box having a base and sidewalls folded up from the base, the sidewalls being held at their ends to form the corners of the box by extruded section corner posts, each corner post including a plurality of elongate channels open at both ends to enable the post to be slid axially on to the ends of adjacent sidewalls to hold the walls together at the corner of the box and in planes substantially perpendicular to the base, and including means comprising a plurality of stacking pegs each having a first and a second extremity enabling one box to be stacked on top of a like box with the two corner posts at each corner of the stack of two boxes so formed being vertically aligned, each said corner post at its top including means for engagement with a first extremity of a stacking peg, said base including adjacent a plurality of its corners means for engagement with a second extremity of a stacking peg, and each stacking peg having an offset configuration whereby each peg is engageable via the first extremity thereof with said engagement means at the top of a corner post and via the second extremity thereof with said engagement means in the base of a like box stacked immediately above, and the two boxes so stacked are positively prevented from moving laterally with respect to each other.
Claim 3
Dependent Claim
65 words
The box of claim 1 wherein the stacking pegs each consist of a flat base member, a first projection extending to one side of the base member and adapted to engage said engagement means in the corner post and a second projection extending to the opposite side of the base member and adapted to engage said engagement means of the base of a like box.
Claim 4
Dependent Claim
33 words
The box of claim 2 wherein the projections on the stacking peg are axially offset, and the base of the box has an aperture adjacent each corner into which the second projection fits.
Claim 5
Dependent Claim
25 words
The box of claim 1 wherein the ends of each sidewall are folded back to form a double thickness section which engages in the channel.
Claim 6
Dependent Claim
27 words
The box of claim 4 wherein the ends of the folded back portions are chamfered and are located at different distances from the base of the box.
Claim 7
Dependent Claim
15 words
The box of claim 4 wherein the folded back portion is glued to the sidewall.
