ABSTRACT:
A method box for making a sturdy and light-tight box and a box thereof in accordance with one embodiment of the present invention includes providing a sheet of material with a first pair of opposing edges and a second pair of opposing edges. The sheet of material is grooved to form first and second pairs of grooves. Each of the first pair of grooves is spaced from one of the first pair of edges to form a first pair of sides and each of the second pair of grooves is spaced from one of the second pair of edges to form a second pair of sides. Next, the first and second pairs of sides are folded up along the first and second pair of grooves and then are secured together to form the box. The method may include additional steps, such as trimming the sheet of material to form the first and second pair of edges, where the steps of trimming and grooving are done in the same step, applying a non-translucent adhesive along each of the first and second pair of grooves to secure the first and second sides of the box together, applying a first layer of material over the first and second opposing edges, and/or cutting the grooves in to the sheet of material at an angle which is greater than the angle at which each of the first and second pairs of sides are located with respect to a base of the box when finished.
