Abstract
Abstract Comparatively large plastic bags, each having the requisite size to accommodate a conventional two-wheel bicycle therein during its shipment and, despite such size, convenient to handle because the bags are detachably connected end-to-end and put up in a supply roll from which each bag is readily removed one at a time when needed. Each bag also has a removable portion which advantageously serves as a tying strip for holding the bicycle handle bars in the plane of the bicycle and thereby facilitating its placement within the bag.

Claim 1
Independent Claim
160 words
A supply of detachable plastic shipping bags comprising an elongated plastic tube put up in a supply roll, transversely oriented heat seals at selected intervals along said tube defining a shipping bag between each adjacent pair of transversely oriented perforations located adjacent each adjacent pair of heat seals delinating the front and rear respectively of each said shipping bag, and in each said delineated shipping bag a second arrangement of transversely oriented perforations spaced from the rear edge thereof delineating a removable tying strip, said first arrangement of perforations being more closely spaced and more in number than the spacing and number of said second arrangement of perforations so as to be operatively effective to promote rupture in said tube before said second arrangement of perforations such that each said shipping bag is first readily detached from said supply roll and each said tying strip thereof forms an uninterrupted tying loop that is then readily detached from said shipping bag.
