Abstract
A disposable, compactable moisture-impervious package for dispensing a stack of premoistened sheets has a pocket portion and a flap portion, each made of a pliable and compactable moisture-impervious material. The pocket portion has first and second walls adhered to each other to provide a compartment between them for receiving the stack of sheets. The sheets are retained in the compartment with their flat surfaces generally parallel to the first and second walls of the pocket. A dispensing opening is provided in one of the walls of the pocket overlying the flat surfaces of the sheets, and a primary seal for the opening prevents the undesirable evaporation of moisture from the sheets. The flap portion of the package extends from a wall of the pocket portion, and is removably securable over the dispensing opening to provide a secondary moisture-impervious seal after the primary seal has been broken.
