Abstract: A compact, economical and easily operated hand tool facilitates reclosing and resealing of paint cans or similar containers that have a frictionally engaged lid and which contain materials that may not be completely used immediately after the initial opening of the can. A pair of handle members are grasped by one hand of the operator and positioned adjacent the rim of the can during use. A drive wheel on one handle member is manually rotated with the other hand and rides around the underside of the rim of the can while a cooperating broader rotatable drum on the other handle member applies seating pressure to successive portions of the lid of the can. Substantially uniform pressure may be applied to all portions of the edge of the lid to effect a complete and reliable sealing of the can.
