Abstract
Abstract A unitary blank for forming a packaging container for a heavy article such as a motor is disclosed, the blank including opposed vertical side and end wall panels, and top and bottom flaps connected with each of the panels, respectively, characterized by the provision in the fold lines between each of a pair of opposed panels and at least one of the flaps connected thereto an H-shaped cut, which cut straddles the fold line and defines a pair of opposed binding tabs generally facing the fold line, whereby when the flap is folded to a horizontal position and the tabs are foldably displaced inwardly, a recess is formed in the edge between the panel and the associated flap for receiving a binding strap arranged circumferentially about the container. Preferably, each H-shaped cut is so arranged relative to the fold line that the binding tabs are of unequal length, so that when they are foldably displaced inwardly, the adjacent edges of the binding tabs overlap, whereby the binding tabs serve both to stabilize the article in the container, and to protect the article against damage by the binding tab. The container blank, which is preferably formed of corrugated fibrous material, may include precrushed portions arranged beneath the binding strap.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
254 words
A unitary blank for forming a container for an article, comprising (a) a generally rectangular blank containing a plurality of vertical fold lines which define pairs of opposed side and end wall panels; (b) said blank including a plurality of top and bottom flaps connected with the upper and lower edges of each of said panels by horizontal fold lines, respectively; (c) the horizontal fold line between one of said panels and the associated top flap connected thereto containing a first H-shaped cut, the horizontal fold line between the panel opposite said one panel and the top flap connected thereto containing a second H-shaped cut opposite and corresponding with the first H-shaped cut, the vertical parallel arms of each of said cuts extending from said panels across the associated horizontal fold line and into the associated top flaps, thereby to define a pair of opposed binding tabs; (d) the height of each of the top flaps which contains portions of the H-shaped cuts generally equalling the width of the remaining pair of panels, each of said cut-containing top flaps containing in its free upper edge a recess opposite said H-shaped cut, whereby when the panels are folded to define a tubular configuration, said recess is arranged opposite the H-shaped cut in said opposite panel, and when the flaps are folded to horizontal positions closing the upper and lower ends of the tube, the binding tabs may be folded inwardly to define in the associated edge a recess for receiving a circumferentially arranged binding strap.
Claim 2
Dependent Claim
254 words
A unitary blank for forming a container for an article, comprising (a) a generally rectangular blank containing a plurality of vertical fold lines which define pairs of opposed side and end wall panels; (b) said blank including a plurality of top and bottom flaps connected with the upper and lower edges of each of said panels by horizontal fold lines, respectively; (c) the horizontal fold line between one of said panels and the associated top flap connected thereto containing a first H-shaped cut, the horizontal fold line between the panel opposite said one panel and the top flap connected thereto containing a second H-shaped cut opposite and corresponding with the first H-shaped cut, the vertical parallel arms of each of said cuts extending from said panels across the associated horizontal fold line and into the associated top flaps, thereby to define a pair of opposed binding tabs; (d) the height of each of the top flaps which contains portions of the H-shaped cuts generally equalling the width of the remaining pair of panels, each of said cut-containing top flaps containing in its free upper edge a recess opposite said H-shaped cut, whereby when the panels are folded to define a tubular configuration, said recess is arranged opposite the H-shaped cut in said opposite panel, and when the flaps are folded to horizontal positions closing the upper and lower ends of the tube, the binding tabs may be folded inwardly to define in the associated edge a recess for receiving a circumferentially arranged binding strap.
Claim 3
Dependent Claim
197 words
A unitary blank for forming a container for an article, comprising (a) a generally rectangular blank containing a plurality of vertical fold lines which define pairs of opposed side and end wall panels; (b) said blank including a plurality of top and bottom flaps connected with the upper and lower edges of each of said panels by horizontal fold lines, respectively; (c) the horizontal fold line between at least one of said panels and the associated flap connected thereto containing an H-shaped cut the vertical parallel arms of which extend from said panel across the horizontal fold line and into the associated flap, the transverse portion of said cut being spaced from the associated fold line, thereby to define a pair of opposed binding tabs of unequal length, whereby when the panels are folded to define a tubular configuration and the flaps are folded to horizontal positions closing the upper and lower ends of the tube, the binding tabs may be folded inwardly toward positions in which the adjacent edges thereof overlap for protecting an article packaged within the container and for defining in the associated container edge a recess for receiving a circumferentially arranged binding strap.
Claim 4
Dependent Claim
197 words
A unitary blank for forming a container for an article, comprising (a) a generally rectangular blank containing a plurality of vertical fold lines which define pairs of opposed side and end wall panels; (b) said blank including a plurality of top and bottom flaps connected with the upper and lower edges of each of said panels by horizontal fold lines, respectively; (c) the horizontal fold line between at least one of said panels and the associated flap connected thereto containing an H-shaped cut the vertical parallel arms of which extend from said panel across the horizontal fold line and into the associated flap, the transverse portion of said cut being spaced from the associated fold line, thereby to define a pair of opposed binding tabs of unequal length, whereby when the panels are folded to define a tubular configuration and the flaps are folded to horizontal positions closing the upper and lower ends of the tube, the binding tabs may be folded inwardly toward positions in which the adjacent edges thereof overlap for protecting an article packaged within the container and for defining in the associated container edge a recess for receiving a circumferentially arranged binding strap.
Claim 5
Dependent Claim
52 words
A blank as defined in claim 2, wherein the horizontal fold line between the panel opposite said one panel and the flap connected thereto also contains a corresponding H-shaped cut opposite the first H-shaped cut, said H-shaped cuts being contained in the horizontal fold lines connecting said top flaps with said panels.
Claim 6
Dependent Claim
63 words
A container blank as defined in claim 2, wherein the horizontal fold line between said one panel and the other flap connected thereto contains a second H-shaped cut opposite said first cut, the parallel portions of said second cut extending vertically across the associated horizontal fold line, whereby a second binding strap receiving recess is defined at the other end of the container.
Claim 7
Dependent Claim
59 words
A container blank as defined in claim 3, wherein said cut-containing pair of opposed panels are provided at their lower ends with second H-shaped cuts that extend from said panels and across the lower horizontal fold lines into the associated bottom flaps, thereby to define a pair of binding strap receiving recesses in the bottom edges of the container.
Claim 8
Dependent Claim
70 words
A container blank as defined in claim 2, and further including means connecting together the adjacent free edges of a pair of said panels when said panels are folded into the tubular configuration, and at least one binding strap mounted circumferentially about the container when the flaps are folded to their horizontal positions, said binding strap extending within said recess to maintain the binding tabs in their folded overlapping condition.
Claim 9
Dependent Claim
22 words
Apparatus as defined in claim 6, wherein portions of the blank beneath said binding strap are precrushed during the blank forming operation.
