Abstract
A self-locking corner structure for trays, cartons, lids, or the like has a generally plainer main panel and first and second side panels foldable along fold lines relative to the main panel to positions normal to each other and to the main panel to form a corner structure. One of the side panels has a flap portion at one end thereof foldable along a fold line to a position parallel and with one of its side surfaces adjacent to the other side panel, the flap portion having a sloping edge. The other of the side panels has a tab portion foldable along a sloping fold line generally parallel and adjacent to said sloping edge with the side panels positioned normal to the main panel and normal to each other and with the flap folded to a position parallel to the other side panel. The tab portion is foldable along the sloping fold line over the sloping edge, and downwardly adjacent the other side surface of the flap, and is held in said folded position to lock the side panels in position normal to each other and the main panel.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
