Abstract

A collapsible box can include a top panel; a front panel hingedly attached to the top panel; a first side panel hingedly attached to the top panel and the front panel; a second side panel hingedly attached to the top panel and the front panel; a rear panel hingedly attached to the top panel, the first side panel, and the second side panel; and a bottom panel hingedly attached to the front panel, the rear panel, the first side panel, and the second side panel; and wherein the front panel defines a frame portion and a lower flap portion connected together by a front line of weakness; wherein the frame portion is coupled to the first side panel, the second side panel, and the bottom panel; and wherein the lower flap portion is coupled to the top panel.

Claims (50)

1. A collapsible box comprising:

a top panel defining a top hinge;

a front panel hinged to the top panel;

a first side panel hinged to the top panel and the front panel;

a second side panel hinged to the top panel and the front panel;

a rear panel hinged to the top panel, the first side panel, and the second side panel;

a bottom panel hinged to the front panel, the rear panel, the first side panel, and the second side panel and defining an internal cavity; and

an access flap configured to provide access to an inner cavity through the top panel and the front panel when the access flap is folded about the top hinge.

2. The collapsible box of claim 1 wherein the rear panel defines a plurality of V-shaped fold lines configured to fold from a planar shape to a truncated pyramidal shape.

3. The collapsible box of claim 1 wherein the rear panel defines a plurality of V-shaped fold lines that intersect a lateral hinge extending at least partially across the front panel, the first side panel, and the rear panel.

4. The collapsible box of claim 1 wherein a lateral hinge extends at least partially across the front panel, the first side panel, the second side panel, and the rear panel, and wherein the lateral hinge is configured to collapse the collapsible box when a user presses inwards on the first side panel and the second side panel along the lateral hinge.

5. The collapsible box of claim 1 wherein:

the top panel comprises a first top subpanel coupled to a second top subpanel;

a lower flap portion is coupled to the first top subpanel by a front hinge;

the first top subpanel defines a second top hinge between the front hinge and the second top subpanel;

a portion of the first top subpanel positioned between the top hinge and the front hinge defines an upper flap portion; and

the access flap of the collapsible box comprises the upper flap portion and the lower flap portion.

6. The collapsible box of claim 1 wherein:

a top tape strip secures a first top subpanel to a second top subpanel;

the first top subpanel is hingedly attached to the top panel by a front hinge;

the first top subpanel defines a top hinge between the top tape strip and the front hinge;

a portion of the first top subpanel positioned between the front hinge and the top hinge defines an upper flap portion; and

the upper flap portion and a lower flap portion together define the access flap of the collapsible box.

7. The collapsible box of claim 1 wherein the front panel defines a front line of weakness comprising a pair of side portions and a baseline portion that extends between the pair of side portions, the baseline portion and the pair of side portions each define a plurality of perforations.

8. The collapsible box of claim 7 further comprising a finger cutout portion that extends downward from the baseline portion in an elongated U-shape.

9. The collapsible box of claim 8 wherein the finger cutout portion defines a thru-cut that extends completely through the front panel.

10. A blank comprising:

a front panel defining a frame portion;

a first top subpanel coupled to the front panel by a front hinge;

a second top subpanel that tapers away from the first top subpanel;

a side panel coupled to the second top subpanel and defining a first side and a second side opposite from the first side, the first side coupled to the frame portion by a first side hinge; and

a rear panel coupled to the second side by a second side hinge parallel to the first side hinge and perpendicular to the front hinge.

11. The blank of claim 10 wherein the front panel defines a front line of weakness comprising a pair of side portions and a baseline portion that extends between the pair of side portions, and the front line of weakness is at least partially defined by a plurality of perforations.

12. The blank of claim 10 wherein:

a first lateral hinge extends at least partially across the front panel, the side panel, and the rear panel;

a second lateral hinge extends at least partially across the front panel, the side panel, and the rear panel; and

the first lateral hinge is parallel to the front hinge and the second lateral hinge is parallel to the first lateral hinge.

13. The blank of claim 10 wherein the rear panel defines a plurality of V-shaped fold lines, and wherein the plurality of V-shaped fold lines intersect a lateral hinge extending across the frame portion between the front hinge and a bottom hinge, and the rear panel is configured to fold from a planar shape to a truncated pyramidal shape.

14. The blank of claim 10 wherein:

a first bottom subpanel is hingedly coupled to the frame portion by a bottom hinge; and

a lateral hinge extends across the frame portion between the front hinge and the bottom hinge.

15. The blank of claim 14 wherein the lateral hinge is a linear hinge.

16. The blank of claim 14 wherein the lateral hinge extends across the frame portion.

17. A blank comprising:

a front panel defining a lower flap portion and a frame portion coupled together by a front line of weakness comprising a pair of side portions, a baseline portion extending between the pair of side portions, and a finger cutout portion extending downward from the baseline portion in a bathtub shape and defining a thru-cut that extends completely through the front panel;

a first top subpanel coupled to the lower flap portion by a front hinge;

a second top subpanel coupled to a side panel coupled to the frame portion, wherein the second top subpanel tapers away from the first top subpanel; and

a rear panel coupled to the side panel.

18. The blank of claim 17 , wherein the pair of side portions and the baseline portion each define a plurality of perforations.

19. The blank of claim 17 wherein the first top subpanel defines a first top hinge, and the second top subpanel defines a second top hinge.
