Stackable open topped box with indented side edges

摘要

A stackable open topped box and a blank from which it is folded are provided in which a fluted sheet material is cut and sulcated to form a box The flutes extend parallel to the side walls of the box and up the height of the end walls. Each side wall has an indent whereof the ends terminate in a diagonal fold inclined upwardly and towards the adjacent end of the box at an angle of 45°. The fluted sheet material originally adjacent the edge of the indent is folded inwards and downwards as a composite flap such that the flutes of the fluted material are generally vertical and the material extends to substantially the bottom of the box. A strip that is approximately beneath the diagonal fold is flush with the inside of the side wall of the box.

1. A stackable open topped box made of a folded blank of fluted sheet material in which two opposite side walls and two opposite end walls are folded at generally right angles along sulcations attaching them to a rectangular bottom of the box wherein flutes of the fluted sheet material extend parallel to the side walls of the box and up the height of the end walls,
wherein the side walls each have an indent extending along the upper edge thereof for a substantial part of the length of the side wall with each end of the indent terminating in a diagonal fold inclined upwardly and towards the adjacent end of the box at an angle of 45° with fluted sheet material originally adjacent the edge of the indent being folded inwards and downwards as a composite flap such that flutes of the fluted material extend at right angles to the flutes of the side walls and the material extends to substantially the bottom of the box and whereof a strip that is approximately beneath the diagonal fold is flush with the inside of the side wall of the box.
