Abstract
Abstract My invention relates to means for manual use for easily and neatly picking up and disposing of obnoxious or unwanted material and includes a relatively stiff, approximately rectangular sheet which is partly inserted into and partly projects from a flexible sleeve secured to the sheet by heat sealing or comparable fastening. The sleeve is widened at its generally open end and is foldable over the sheet. The sheet may have a transverse slit in it to receive the user''s thumb in order to make a better engagement with the sheet and to stiffen the sheet.
