  • Patent number: 5655682
    Abstract: A package for dispensing articles formed from individual plastic sheets is disclosed. The package includes a stack of the articles thermally welded together at one edge of the stack, each article having a tear line of longitudinally aligned interrupted cuts formed thereon to facilitate removal of each article from the stack. A plastic wrapping forms an envelope around the stack and a removable mask on the front side of the envelope may be removed to expose an article-removal opening. After the mask is removed, the individual articles may be removed, one at a time, from the package by pulling the article through the article-removal opening and tearing the article from the stack at the tear line. The stack of articles are kept in neat order until dispensed and contaminating exposure of the pre-dispensed articles is minimized. The package includes holes formed therethrough for hanging the package and adhesive patches on the back surface of the envelope to secure the package to a surface.
