发明名称 BUSINESS FORM WITH PROTECTIVE COVER SHEET
摘要 An improved credit card formset having multiple transaction slips with a cover sheet for any transaction slips formed with an integral duplicating carbon surface, such as a carbon-on-back (COB) slip. The cover sheet is attached by bonding to one end of the COB slip. When the COB slip is detached from the formset the attached cover sheet is sized to overlay the duplicating carbon surface and thereby prevent undesired user contact with the carbon. Any carbonless copy paper (CCP) in the credit card formset or other pack of business forms is similarly covered by an attached cover sheet when the CCP sheet is removed from the pack to prevent undesired user contact with the resin material in the CCP sheet.
