Abstract

Disclosed herein is a one piece box that tips back to open and is formed out of one single faced cardboard blank of a conventional aspect and parallelepiped shape comprising, in the closed position, two shells, the open parts of which face each other on opposite sides and are joined on the median longitudinal axis of a base wall, common to both, which, through simple deformation of the material along the said axis, constitutes the main rotation pivot for opening the box.

Claims

1. A one piece box which may be tipped back to open for packing industrial products, particularly footware, comprising,

first and second shells, each said shell having an open part with said two open parts facing each other when said shells are positioned to provide a closed box,

a base wall common to both said shells and having a median longitudinal axis,

means for joining said shells and for providing for rotation of said shells located along said median longitudinal axis of said base wall,

each said shell including an opposite wall parallel to said base wall, and having an edge parallel to said median longitudinal axis of said base wall,

a closure member pivotally joined to said first shell along said opposite wall edge,

said closure member having a wall surface and three side walls perpendicular to said wall surface and directed toward said second shell, and

said wall surface being sized to fit over said second shell opposite wall so that when said open parts are positioned to provide a closed box, said closure member provides means positioned to enclose said second shell opposite wall.

2. The one piece box according to claim 1, wherein said shells and said joining and rotation means are constituted by a same flexible material,

said shells being joined by said flexible material on said median longitudinal axis of said base wall common to both said shells so that said joining or rotation means for opening said box operates through simple deformation of said material along said axis.
