Abstract
The disclosure relates to containers and other shaped articles (e.g., trays and dishes) for containing articles such as food products (e.g., cuts of meat and poultry or liquid-sensitive electronic parts) in shaped articles in which a wicking material is interposed between two thermoformed trays, at least one of which is perforated. Liquid can flow through the perforated tray into the wicking material and then elsewhere (e.g., to a cavity) in the space between the two trays. The disclosure also relates to hollow shaped articles (e.g., bottles and jars) for containing fluids. In manufacture of such hollow shaped articles, the wicking material serves as a manufacturing aid and can be removed after formation of the article.
