The invention encompasses a system by which a leading T-shirt bag may be removed from a rack while initiating the opening of the bag mouth of the next ensuing T-shirt bag, but without also simultaneously pulling out and opening in succession subsequent T-shirt bags of the pack. The invention accomplishes this by modifying the form of the conventional T-shirt bag by placing a second lower slightly offset horizontal tear slot below the horizontal slot on the center mounting tab by which the tab is held on the hook of the dispensing rack. The offset slot creates a narrow bridge on one end and a wider bridge on the other end of the slot. A glue spot is provided offset from the center toward the side with the narrower bridge, between the back of the forward bag and the front of the subsequent bag. When the leading T-shirt bag is filled and subsequently pulled away, the wider bridge first ruptures and the narrower bridge, coupled with the offset glue spot, works to pull open only the next bag. The narrower bridge and the glue spot connection are broken when the opened bag is later and removed.

[ I claim:] [1.] A stack of plastic T-shirt bags for mounting on a rack having an upwardly extending supported backing structure from which extend forwardly a pair of spaced apart parallel rods, between which is a centrally disposed hooking element also supported by the backing structure, each bag having a front and back wall secured together along their side, bottom and top edges, the joined top edges being centrally cut out to provide a bag mouth defined laterally by a pair of handles, and further defined by a pair of bottom edges extending between the handles, the inner central portion of the last said bottom edges having upwardly extending centrally disposed detachable projections, said projections having upward and side edges, upper transverse registering slots extending between, but spaced from, the projections' side edges, for mounting on the centrally disposed hooking element of the rack, and parallel lower registering slots having first and second ends, said lower slots also extending between the projections' side edges, the first end of each of the lower slots being more proximate to the adjacent side edge of the detachable projection than the second side edge is to its adjacent side edge of said projection; and the back wall of each bag being lightly adhered to the front wall of the next ensuing bag only at a spot offset from an imaginary vertical line extending centrally through the projection and disposed adjacent a parallel imaginary vertical line extending tangentially to the side edge of the projection most proximate to the first end of the lower slot;whereby, when the leading bag of the stack is pulled forwardly on the rods of the rack to open said leading bag, the second end of each lower slot of its detachable projections is initially ruptured, and the front wall of the next ensuing bag of the stack is opened and pulled forward on the rack rods until adherence of the glue spot between the back wall of the leading bag and the front wall of the next ensuing bag is ruptured, immediately following which the area between the first end of each bottom slot and its most proximate edge of the projection of the leading bag is also ruptured;thereby the subsequent ensuing bags are not simultaneously pulled forward as each leading bag is removed from the rack.
