  • Patent number: 4671404
    Abstract: A disposable support for food articles such as tacos is made from a paper-like material folded and interlocked to form a generally triangular shape with an opening in upright inverted V-shaped faces of the support that forms a cradle for holding the food article. The disposable support is formed from a one-piece foldable sheet folded into three sections and having a first panel, a second panel adjacent the first panel, a first fold separating the first and second panels, a third panel adjacent the second panel, and a second fold separating the second and third panels. An elongated opening extends through the first and second panels across the first fold. An interlocking tab at the free end of the third panel is arranged so that when the sheet is folded across the first and second folds into flat form and the third panel is folded inside the first and second panels, the tab is located adjacent the first fold above slotted openings formed in the first and second panels by the large opening therein.
