Abstract
Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, and severable into individual carriers with integral handles. For each carrier, integrally joined band segments define container-receiving apertures. Moreover, an integral handle is joined at its ends respectively to middle portions of two outer segments, which are joined to one cross segment at a node. Stresses are distributed from each end of the handle, through the outer segment having such end joined to a middle portion thereof, to two cross segments. Perforated lines divide alternate cross segments into half segments and facilitate severance of such stock to form the individual carriers. Each half segment has an aperture-defining edge configured to provide means, which may comprise a nub, for countering tendencies of such half segment to neck down or to break. The handle has a middle leg, which is joined to the node via a frangible joint, as defined by a perforated line extending across the middle leg. The frangible joint is designed to break away when stressed.
