发明名称 Easy open flexible bag filled with compressed flexible articles and method and apparatus for making same.
摘要 <p>An easy open flexible bag (15) containing one or more stacks of flexible articles (20) maintained in a state of compression in a direction substantially parallel to their thickness. For products such as disposable absorbent baby diapers, catamenial pads, incontinent briefs and the like, the degree of compression within the bag may be as much as 50% or more when compared to the uncompressed thickness of the stack of articles in question. In a particularly preferred embodiment, the bag totally encloses the stack or stacks of compressed flexible articles and exhibits a substantially rectilinear shape. The bag preferably includes an integral carrying handle. The end (30,31) panels and at least one pair of either the front and back (40,41) or the top and bottom (51,50) panels of the bag are subject to tension imposed by the stack of compressed flexible articles. This leaves at least one pair of panels, preferably the top and bottom panels, in a substantially untensioned condition. One of the substantially untensioned top and bottom panels contains an easily visible, unobstructed tear initiating device (67) which comprises a portion of the easy open device for the bag. The tear initiating device can be readily activated by the end user's fingers to create an aperture traversing at least one corner of the bag. Partially pre-erected easy open flexible bags of the present invention are filled by over-compressing the flexible articles to a dimension which is smaller than the interior of the bag and thereafter allowing the articles to expand slightly once they have been inserted within the bag. Preferred apparatus for compressing the flexible articles and inserting them into partially pre-erected flexible bags of the present invention are also disclosed.</p>
