发明名称 Easy opening plastic bag pack
摘要 <p>A pack of easy opening handleless type or T-shirt type plastic bags is provided which is particularly suited for use in packaging grocery produce or the like and which is adapted for being suspended in desired lengths from a rack for being serially opened and removed from the rack to provide the easy opening desired by the user. The bags of either type include integrally formed front and rear walls and gusseted side walls extending inwardly towards each other to terminate in close proximity to each other. The walls have top portions defining an open mouth. The T-shirt type bags include laterally-spaced handles extending upwardly from the mouth portion on each side of the bag in its open position. The front and rear walls and the gusseted side walls, along with the handles in the T-shirt type bags, are further folded over onto each other along a longitudinal axis of the bag to define eight superimposed wall layers in the bag. A seal of the star seal type secures the bottoms of the eight superimposed wall layers together to close the bottom of the bag. Detachable tabs extend upwardly from each of the eight wall layers at the top portion thereof and are in superimposed positions. Each of the detachable tabs includes an aperture for mounting the tabs on a tab retaining device of a rack. At least the front two tabs in the handleless bag and the front four tabs in the T-shirt bags are constructed to be front-side-free for aiding in easy opening of the bag. One form of mounting tabs for either the handleless type or the T-shirt type plastic bags is constructed to be detachable from the bags and remain with the rack as the bags are serially opened and removed from the pack and from the rack. Another form of mounting tabs for either the handleless type of T-shirt plastic bags is constructed to be detachable from the rack and remain with the bag as the bags are serially opened and removed from the pack and from the rack.</p>
