Box construction

Abstract

1,049,965. Boxes. SOMERVILLE INDUSTRIES Ltd. Nov. 1, 1965, No. 46082/65. Heading B8P. A knock-down box is folded-up from a paperboard blank to have a base 10, double thickness side walls 14, 16 and end walls 22, 24 also of double thickness, strips 18 hinged along the inner panels 16 of the side walls by readily tearable fold lines being glued to strips 12 connected between the base and the outer side walls 14 by parallel fold lines, so that when the strips 12 are folded-over and the box walls erected, a three-ply flange is formed along the long sides of the base. The end walls 22, 24 are folded-over with a two-ply flange 20 along the edges of the base 10. Diagonally folded flaps 26, Figs. 1, 5 (not shown), on the ends of the outer side walls 14, are glued to the outer end walls 22. The box is transported before erection with the side walls 14, 16 folded-in flat against the base 10, and the end walls 22, 24 extending beyond the ends of the base, Fig. 3 (not shown). Erection is effected by folding- up the end walls 22, 24, Fig. 5 (not shown). The flaps 26 simultaneously draw up the side walls 14, 16. As the latter bend up, the readily tearable fold lines connecting the strips 18 to the inner side panels 16 are pulled apart. The inner end walls 24 are then folded inwards to engage tabs 30 in notches 32 in the inner side walls, and hold the box erect. Another similar box may be telescoped over the first in the manner of a lid.
