Modular box assembly
A modular box assembly includes a box having a top end, an opposed bottom end, and side panels extending from the top end to the bottom end. A bottom panel is disposed at the bottom end such that the side panels and the bottom panel define a box cavity and the top end defines a box opening. A shoulder is attached to two side panel and extends inward from the side panels into the box cavity, wherein each shoulder is spaced from the top end a predetermined distance. A box top covers the box opening, the box top being selectively movable about and between a closed position and an open position. In the closed position, the top panel engages the shoulders to support the top panel, and in the closed position an upper surface of the top panel is substantially flush with the top end of the box.
1. A box comprising:
a side panel;
a bottom panel attached to the side panel, the side panel and bottom panel at least partially defining a box cavity, the bottom panel defining:
four bottom panel corners;
a center subpanel defining a rectangle, the rectangle comprising:
a first pair of edge fold lines extending in a longitudinal direction;
a second pair of edge fold lines extending transverse to the first pair of edge fold lines; and
four subpanel corners, each subpanel corner joining one of the first pair of edge fold lines to one of the second pair of edge fold lines; and
a V-shaped fold line comprising a first fold line extending from a first one of the bottom panel corners to a longitudinal center line of the bottom panel and a second fold line extending from a second one of the bottom panel corners to the longitudinal center line, wherein the first fold line and second fold line meet at an apex along the longitudinal center line; and
an insulating liner received in the box cavity.
2. The box of claim 1 , wherein the bottom panel is symmetric about the longitudinal center line.
3. The box of claim 1 , wherein the V-shaped fold line is a first V-shaped fold line, and the bottom panel further comprises a second V-shaped fold line.
4. The box of claim 1 , further comprising a first corner fold line extending from the first one of the bottom panel corners to a first one of the subpanel corners.
5. The box of claim 1 , wherein the bottom panel is symmetric about a transverse center line that is perpendicular to the longitudinal center line.
6. The box of claim 1 , wherein the bottom panel comprises a center fold line substantially aligned with the longitudinal center line.
7. The box of claim 1 , wherein the side panel is a first side panel, and the box further comprises:
a third side panel opposed to the first side panel, a second side panel positioned between and coupled to the first side panel and the third side panel, and a fourth side panel opposed to the second side panel, the fourth side panel being positioned between and coupled to the first and third side panels.
8. The box of claim 7 , wherein a center fold line extends across each of the bottom panel, first side panel, and the third side panel.
9. The box of claim 7 , further comprising:
a first wing attached to a side of the first side panel; and
a second wing attached to the first wing and to the second side panel.
10. The box of claim 9 , wherein the box is symmetric about the longitudinal center line.
11. The box of claim 1 , wherein:
the box is configured to collapse to a collapsed configuration; and
a width between the first pair of edge fold lines is approximately a thickness of the box in the collapsed configuration.
12. The box of claim 9 wherein:
each one of the panels or wings defines a layer; and
the thickness of the collapsed configuration comprises eight layers.
