Abstract
A panel assembly including a main panel, a first side panel, a second side panel, a first tab, a second tab, and an extension. The first tab defines a planar notch into which the extension is positioned to restrict movement of the first side panel and the second side panel.
Claims18
A panel assembly, comprising:
- a main panel extending within a plane which defines an X-axis and a Y-axis perpendicular to the X-axis;
- a first side panel extending from the main panel along a Z-axis perpendicular to the X-axis and the Y-axis;
- a second side panel extending from the main panel along the Z-axis, the second side panel perpendicular to the first side panel;
- a first tab extending from the first side panel along the X-axis and comprising a first portion, a second portion, and a third portion, the first, second, and third portions lying in the same plane and collectively defining a notch;
- a second tab extending from the second side panel along the Y-axis;
- and
- an extension extending from the second tab in the Y-axis direction, the extension interlocking with the notch, wherein the second tab is parallel with the first tab along the X-axis and Y-axis, and the second tab overlaps the first tab along the Z-axis such that the extension is co-planar with the first tab along the X-axis and the Y-axis.

A method of forming a panel assembly, the method comprising:
- receiving an unformed panel assembly, the unformed panel assembly comprising a main panel extending within a plane which defines an X-axis and a Y-axis perpendicular to the X-axis, a first side panel extending within the plane from the main panel along the X-axis, and a second side panel extending within the plane from the main panel along the Y-axis, the unformed panel assembly further comprising a first tab extending from the first side panel, the first tab comprising a first portion extending from the first side panel along the X-axis, a second portion extending from the first portion in the X-axis, and a third portion extending from the second portion in the Y-axis, the unformed panel assembly further comprising a second tab extending from the second side panel along the Y-axis, the second tab comprising an extension extending from the second tab along the Y-axis;
- bending the extension 180° such that the extension overlaps with the second tab;
- bending the first tab such that the first tab extends from the first side panel along a Z-axis perpendicular to the X-axis and the Y-axis;
- bending the second tab such that the second tab extends from the second side panel along the Z-axis;
- bending the first side panel such that the first side panel extends from the main panel along the Z-axis;
- and
- bending the second side panel such that the second side panel extends from the main panel along the Z-axis and the extension is positioned between the first portion, the second portion, and the third portion of the first tab, wherein the second tab is parallel with the first tab along the X-axis and Y-axis, and the second tab overlaps the first tab along the Z-axis such that the extension is co-planar with the first tab along the X-axis and the Y-axis.
