Claim 1
Independent Claim
314 words
A four sided box formed from a generally rectangular blank of sheet material cut, scored and folded into said box having a bottom, two opposite side walls and two opposite end walls; each end wall comprising an outer end panel hinged to the bottom, an inner end panel hinged to the top of the outer end panel, a first intermediate end partial panel hinged to a side edge of one of the side walls, a first intermediate full panel hinged to the top of the first intermediate end partial panel and folded outwardly to lie flat against the outer face of the said first partial panel, a second intermediate end partial panel hinged to the opposite side edge of the other of the side walls, and a second intermediate full panel hinged to the top of the second intermediate end partial panel and folded inwardly to lie flat against the inner face of the said second partial panel, the sum of the widths of the Said partial panels not exceeding the width of the end wall, said intermediate panels being positioned between the inner and outer end panels, the said panels of each end wall being cut out to provide a handhole for carrying the box; each side wall comprising an outer side panel hinged to the bottom, an inner side panel hinged to the top of the said outer side panel, and side partial panels each hinged to the side edge of an inner end panel, the inner and outer side panels being superimposed with the side partial panels positioned therebetween; the bottom comprising inner bottom partial panels hinged to the bottom edges of the opposite inner side panels, the sum of the widths of the said inner bottom partial panels being approximately equal to the width of the bottom, whereby the said inner bottom partial panels will butt along their facing edges.

A four sided box formed from a generally rectangular blank of sheet material cut, scored and folded into said box having a bottom, two opposite side walls and two opposite end walls; each end wall comprising an outer end panel hinged to the bottom, an inner end panel hinged to the top of the outer end panel, a first intermediate end partial panel hinged to a side edge of one of the side walls, a first intermediate full panel hinged to the top of the first intermediate end partial panel and folded outwardly to lie flat against the outer face of the said first partial panel, a second intermediate end partial panel hinged to the opposite side edge of the other of the side walls, and a second intermediate full panel hinged to the top of the second intermediate end partial panel and folded inwardly to lie flat against the inner face of the said second partial panel, the sum of the widths of the Said partial panels not exceeding the width of the end wall, said intermediate panels being positioned between the inner and outer end panels, the said panels of each end wall being cut out to provide a handhole for carrying the box; each side wall comprising an outer side panel hinged to the bottom, an inner side panel hinged to the top of the said outer side panel, and side partial panels each hinged to the side edge of an inner end panel, the inner and outer side panels being superimposed with the side partial panels positioned therebetween; the bottom comprising inner bottom partial panels hinged to the bottom edges of the opposite inner side panels, the sum of the widths of the said inner bottom partial panels being approximately equal to the width of the bottom, whereby the said inner bottom partial panels will butt along their facing edges.
Claim 3
Dependent Claim
206 words
A blank made from a generally rectangular sheet adapted for folding into a four sided box having a bottom, two opposite side walls and two opposite end walls comprising generally parallel horizontal and vertical score lines defining the bottom and two opposite outer side panels hinged to the bottom and adapted to form the opposite side walls, outer end panels hinged to the ends of the bottom along the said vertical score lines, inner end panels hinged to the said outer end panels along score lines parallel to the said vertical score lines, intermediate end partial panels hinged to the side walls along the said vertical score lines, the sum of the widths of the said partial panels from the said vertical score lines at each end not exceeding the width of the said end, and intermediate end full panels hinged to the intermediate end full panels hinged to the intermediate end partial panels along score lines which are normal to the said vertical score lines and opposite the outer end panels, whereby the said blank can be set up to form a box having the said end walls formed of five superimposed panels with the intermediate panels interposed between the inner and outer end panels.
Claim 4
Dependent Claim
206 words
A blank made from a generally rectangular sheet adapted for folding into a four sided box having a bottom, two opposite side walls and two opposite end walls comprising generally parallel horizontal and vertical score lines defining the bottom and two opposite outer side panels hinged to the bottom and adapted to form the opposite side walls, outer end panels hinged to the ends of the bottom along the said vertical score lines, inner end panels hinged to the said outer end panels along score lines parallel to the said vertical score lines, intermediate end partial panels hinged to the side walls along the said vertical score lines, the sum of the widths of the said partial panels from the said vertical score lines at each end not exceeding the width of the said end, and intermediate end full panels hinged to the intermediate end full panels hinged to the intermediate end partial panels along score lines which are normal to the said vertical score lines and opposite the outer end panels, whereby the said blank can be set up to form a box having the said end walls formed of five superimposed panels with the intermediate panels interposed between the inner and outer end panels.
Claim 5
Dependent Claim
57 words
The blank of claim 2 in which an inner side panel is hinged to each outer side panel along a score line generally parallel to the score line connecting the outer side panel to the bottom, whereby the inner and outer side panels can be superimposed in the setup box to form the said opposite side walls.
Claim 6
Dependent Claim
74 words
The blank of claim 3 in which an inner bottom partial panel is hinged to each inner side panel along a score line generally parallel to the score line connecting the inner and outer side panels, the sum of the widths of the said inner bottom partial panels being approximately equal to the width of the bottom, whereby the said inner bottom partial panels will butt along their facing edges in the setup box.
