Abstract

A blank includes a top, the top connected to a first top side tab, a second top side tab, a top front tab, and a back tab; a bottom, the bottom defining at least one connection aperture, the bottom connected to a first bottom side tab, a second bottom side tab, a bottom front tab, and the back tab; the first bottom side tab connected to a first cover tab, the first cover tab connected to a first connection tab; the second bottom side tab connected to a second cover tab, the second over tab connected to a second connection tab; the blank formable into a box by connection of the first connection tab to at least one connection aperture and by connection of the second connection tab to at least one connection aperture.

Claims (34)

1. A blank comprising:

a top, the top connected to a first top side tab, a second top side tab, a top front tab, and a back tab; and

a bottom, the bottom defining a connection aperture, the bottom connected to a first bottom side tab, a second bottom side tab, a bottom front tab, and the back tab;

the first bottom side tab connected to a first cover tab;

the second bottom side tab connected to a second cover tab;

the blank formable into a box by connection of at least one connection tab to one connection aperture, wherein at least one cover tab is arranged abutting an external surface of the bottom front tab,

wherein each cover tab is connected to at least one connection tab, wherein each connection tab is coincident with the bottom front tab in blank arrangement, and wherein each connection tab is configured to be detached from the bottom front tab,

wherein the top front tab comprises at least three tabs, each tab arrangeable to contact an end of the bottom front tab, wherein at least two of the three tabs are of a length that is about the same as a length of the bottom front tab,

wherein an initial area ratio R A i is the area of the first cover tab, the second cover tab, and the bottom front tab divided by the area of the front side, and wherein the initial area ratio R A i is not greater than 1.2.

2. The blank of claim 1 , the bottom further comprising an aperture cover at least partially covering the connection aperture.

3. The blank of claim 2 , wherein a portion of the first connection tab proximate the first cover tab defines a radius, and wherein a portion of the second connection tab proximate the second cover tab defines a radius.

4. The blank of claim 1 , wherein the top front tab is of a length that is less than a length of the bottom front tab.

5. The blank of claim 4 , wherein the length of the top front tab is at most 75% of the length of the bottom front tab.

6. The blank of claim 1 , wherein the top front tab is of a width that is about equal to a width of the bottom front tab.

7. A box formed from a blank, the box comprising:

a top, the top connected to a first top side tab, a second top side tab, a top front tab, and a back tab;

a bottom, the bottom, the bottom connected to a first bottom side tab, a second bottom side tab, a bottom front tab, and the back tab,

the back tab defining a back side of the box,

the bottom front tab contacting the top front tab defining a front side of the box,

the first bottom side tab contacting the first top side tab defining a first side of the box,

the second bottom side tab contacting the second top side tab defining a second side of the box;

a connection mechanism defined proximate the front side of the box, the connection mechanism comprising an overlap of material along the front side of the box,

wherein the front side of the box defines a length,

wherein the top front tab is of a width that about equal to a width of the bottom front tab,

wherein the top front tab comprises at least three tabs, each tab arrangeable to contact an end of the bottom front tab, wherein at least two of the three tabs are of a length that is about the same as a length of the bottom front tab, and

wherein an initial area ratio R A i is the area of the first cover tab, the second cover tab, and the bottom front tab divided by the area of the front side, and wherein the initial area ratio R A i is not greater than 1.2.

8. The box of claim 7 , wherein the material along the front side of the box defines an area ratio R A wherein R A is at most 2.50.

9. The box of claim 8 , wherein R A is at most 2.25.

10. The box of claim 8 , wherein R A is at most about 1.75.

11. The box of claim 7 , wherein the front side of the box is not greater than two-ply along at least 70% of the length.

12. The box of claim 11 , wherein the front side of the box defines a length and wherein the front side of the box is not greater than two-ply along at least 75% of the length.

13. The box of claim 11 , wherein the front side of the box defines a length and wherein the front side of the box is not greater than two-ply along at least 78% of the length.

14. The box of claim 11 , wherein the front side of the box defines an area density ρ A and wherein ρ A is less than 0.70.

15. The box of claim 11 , wherein the front side of the box defines an area density ρ A and wherein ρ A is less than 0.60.
