Abstract
Abstract A stack of small liquid-saturated folded disposable towels is sealed within a disposable container under a cover sheet, which protects and preserves the contents during storage prior to use. When the cover sheet is stripped from the peripheral flange to which it is attached, by grasping a loose tip over a depressed corner of the flange, it exposes a removable lid having a pair of opposite edges flexibly inserted under overhanging projections on a framing ridge on a dished panel, which is secured to a shelf within the rim of the receptacle. Towels are dispensed through a lobular cross-shaped aperture in the center of the dished panel, which is surrounded by a flat margin joined by sloped walls to a ledge under the framing ridge, which provides a supporting surface for the edges of the lid. The sides of the container are concavely indented and vertically ridged to stiffen and decorate them. The bottom is also inwardly dished for the same purposes.
