    Patent number: 5056159
    Abstract: A tray-bib (10) has a tray portion (12) covering a wearer's lap and a bib portion (14) covering a wearer's chest and stomach. The tray (12) forms a cavity with a bottom (18), sides (20), and ends (22). The bib portion (14) tears along perforations (24) and folds up from a top portion (16) of the tray (12) to direct spillage into the tray (12).
