Abstract
An object that may be shaped by means of folding in a tri-dimensional box-like structure, comprises a main blank consisting of a bottom panel defined by score lines along the sides and by lateral sections extending beyond said score lines; at least, one section is lateral and consists of several members that may be folded among themselves in a box-like way, so as to form a side of the structure with an, at least partially, box-like shape.
Claims10
A plurality of blanks for forming a box-like structure, a plurality of slideways, and a plurality of drawers, comprising:
- a first blank including a rectangular back panel defined by two pairs of opposed score lines, a plurality of panel members extending outwardly from said score lines, said panel members foldable on each other to form, respectively, a bottom wall, an upper wall and side walls each connected to the back panel;
- a plurality of slideway blanks for defining hollow rectangular slideways for application on inner surfaces of said side walls of said first blank;
- a plurality of second blanks including a rectangular central panel defined by two pairs of opposed score lines, a plurality of panel members extending outwardly from said score lines, said panel members foldable relative to each other to form a hollow front wall, a back wall, and hollow side walls, said side walls having a rectangular cross section and each having a longitudinal offset for sliding engagement with said slideways;
- said first blank when folded defining a self-supporting, box-like, drawer-supporting structure having an open front for slidably receiving a plurality of drawers carried on said guideways;
- each said second blank when folded being a self-supporting box-like structure in the form of a drawer that is slidably received in the supporting structure formed from said first blank structure.

A box-type article having drawers and formed from a plurality of flat blanks, said article comprising:
- (a) an enclosure formed from a first blank including a rectangular back panel defined by two pairs of opposed score lines, a plurality of panel members extending outwardly from said score lines, each of said panel members being foldable on itself to form, respectively, a bottom wall, a upper wall, and side walls, each of which is connected with the back panel and each of which includes a frame panel between said folded panel members, said enclosure having an opening surrounded and defined by said frame panels of said blank, said frame panels lying in a single plane and forming a frame around said opening;
- (b) a plurality of generally rectangular slideways secured to the inner surfaces of said side walls, said slideways each formed from a blank having a plurality of connected rectangular panels to define an elongated hollow rectangular member having a rectangular cross section when assembled, said slideways having a longitudinal axis substantially perpendicular to said back panel;
- (c) a plurality of drawers, each drawer defined by a second blank including a rectangular central panel defined by two pairs of opposed score lines, a plurality of panel members extending outwardly from said score lines, said panel members foldable about their respective score lines to define a hollow front wall, a back wall, and hollow side walls, said side walls having a rectangular cross section and each said side wall having a longitudinal offset for sliding engagement with said slideways;
- (d) said first blank when folded defining a self-supporting box-like drawer-supporting structure having an open front for slidably receiving a plurality of drawers carried on said slideways, each said second blank when folded being a self-supporting, box-like structure in the form of a drawer having overhanging side panels defined by said longitudinal offset and that are slidably received in the supporting structure formed from the first blank and slidable along said slideways.
