Abstract
Abstract The disclosure is of a tab-pulling device comprising a simple dovetail slide that grips a tab of a blow molded object between it and a planar, stationary jaw. As the tab-pulling jaw moves downward, a plunger or pusher finger carried thereon is projected outward to strip the tab from the movable jaw.
