T-SHIRT TYPE PLASTIC BAG PACK ADAPTED TO LEAVE NO RESIDUE ON A SUPPORTING RACK

摘要

A pack of T-shirt type plastic bags which are preferably self-opening are adapted to be mounted on a support rack and leave no residue on the support rack when removed therefrom. The T-shirt plastic bags include front and rear walls integrally joined at their sides and secured at their bottoms and defining an open mouth portion at the top of the walls, laterally-spaced upwardly-extending handles on each side at the top and each having an aperture therein for mounting the handles on respective support arms of a rack, and a detaching central tab at the top of each of the walls and each having an aperture therein for mounting the central tabs on a tab retaining device on the rack. The aperture in the tab of at least the rear wall has a nick formed in the wall near the top thereof to propagate a tear through the tab for detaching the tab from the rack while retaining sufficient strength in the portion of the tab above the mounting aperture to prevent premature tearing of the tab and detaching from the rack. The mounting aperture in the tab of both the front and rear walls of the bag have a maximum width dimension in the relaxed condition thereof which is less than and a minimum width in the stretched condition thereof which is greater than a predetermined maximum width of a conventional tab retaining device of the "D-ring" type on the rack to adapt the tab mounting apertures of the bag to be stretched over the tab retaining device of the rack when the bags are mounted on the rack to prevent wedging of the detaching tabs behind the tab retaining device of the rack for complete detachment of the tabs from the rack.
