Abstract
A method of forming a container () includes heating two webs of material and indexing the webs into a vacuum thermoformer () which forms first () and second trays () simultaneously, wherein the second tray is disposed within a space of the first tray to define a reservoir () therebetween. A portion of the first tray is brought into contact with a flange portion of the second tray, and joined by a heat seal within the vacuum thermoformer. A punch device within the vacuum thermoformer perforates a drain aperture () in a central region of the bottom of the second tray, such that the drain aperture is in fluid communication with the reservoir. The cut-out section is adhered to the bottom of the first tray to eliminate the presence of any scrap material. The joined first and second tray is indexed out of the vacuum thermoformer and trimmed to separate an assembled container from the web supply.
