## Abstract

The invention relates to a one piece blank of a corrugated cardboard sheet material designed for forming a belt intended to form a box having a length L, a width W and a height H, wherein this blank includes a main rectangular body (10) extending along a longitudinal direction and two protruding rectangular parts (11, 12) extending in a transverse direction and symmetrically with regard to the main body, so as to define two perpendicular branches, a first branch being defined by the main body and a second branch defined by the protruding parts, the main body (10) having a width (D1) larger than the length L and a length (D2) larger than at least twice the width W plus the height H (2W+2H) and each of the protruding parts having a length (d1) larger than the height H or the width W and a width (d2) larger than the width W or the height H.

## Claims

### Claim 1

A method of manufacturing a belt from a blank and provided in a stack of blanks, the blank comprising a one piece blank of a corrugated cardboard sheet material designed for forming a belt intended to form a box having a length L, a width W, and a height H,
wherein the blank includes a main rectangular body extending along a longitudinal direction and two protruding rectangular parts extending in a transverse direction and symmetrically with regard to the main body, so as to define two perpendicular branches, a first branch being defined by the main body and a second branch defined by the protruding parts, the main body having a width larger than the length L and a length larger than at least twice the width W plus the height H and each of the protruding parts having a length larger than the height H or the width W and a width larger than the width W or the height H;
wherein, after removal of the blank from the stack, the blank is then cut to reduce the length and/or the width of the branches of the blank so that the branches are adapted to the dimensions of the belt and wherein two first parallel fold lines are created between the main body and the protruding parts to define two secondary panels which are intended to form the third or the fourth lateral wall of the box and determine the height H and the width W of the box and at least three second parallel fold lines are created in the main body to define four main rectangular panels which are intended to form the top, the bottom and the first and second lateral walls of the box and determine the length L and the width W or the height H of the box, first parallel fold lines being perpendicular to the second fold lines and a secondary panel being provided on each of two opposing sides of one of the main panels.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the blank is cross-shaped and each of the protruding parts has a length larger than the height H and a width larger than the width W, and is positioned relative to the main body so that it is spaced from each end of the main body by a distance larger than the height H or the width W plus the height H.

### Claim 3 (depends on 2)

The method according to claim 2, wherein one of the main panels of the belt intended to form the bottom of the box being provided on each of two opposing sides with a secondary panel intended to form the third or the fourth lateral wall of the box and each of the secondary panels being connected to a flap, each of the protruding part has a length larger than the height H and the width w″ of said flap.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the blank has a T-shape and each of the protruding parts has a length larger than the width W and a width larger than the height H.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the belt having four rectangular main panels intended to form the top, the bottom and the first and second lateral walls of the box and at least one pair of first flaps being connected on opposing sides of a main panel, the width of the main body is equal to or larger than the length L plus twice the width w′ of a first flap of the box.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the belt having four rectangular main panels intended to form the top, the bottom and the first and second lateral walls of the box and the main panel of the belt intended to form the top of the box being connected to a third flap which is intended to be glued on the second lateral wall to close the box, the length of the main body is equal to or larger than twice the width W and the height H plus the width w of the third flap of the box.

### Claim 7 (depends on 1)

The method according to claim 1, wherein the first parallel fold lines are created in the main body to define at least one pair of first flaps which are connected on opposing sides of a main panel.

### Claim 8 (depends on 1)

The method according to claim 1, wherein four second parallel fold lines are created in the main body to define a third flap connected to the main panel intended to form the top of the box.

### Claim 9 (depends on 1)

The method according to claim 1, wherein the secondary panels being provided on each side of the main panel intended to form the bottom of the box, a third fold line, parallel to the first fold lines, is created in each protruding part to define a flap.
