发明名称 Easy opening bag pack and supporting rack system and fabricating method.
摘要 <p>A plurality of gussetted bags (11) of the T-shirt type or of the flat top type are provided with bag mounting apertures (20) through all of the bag walls (13, 15, 14) on opposed sides thereof and with additional cuts (21) in the front wall portion (13) and the front section of the gussetted side wall portions (15) and in communication with the bag mounting apertures (20) therein for effectively enlarging such apertures. A rack (25) mounts bag pack (10) through the mounting apertures (20) by means of stub shaft supports (26) laterally spaced from each other and of a length less than the outwardly extending dimensions of an open bag and greater than the thickness of the bag pack and having an enlarged portion (27) on the free outer ends thereof of greater dimensions than the bag mounting apertures. With this construction, the front wall (13) and the front section of the gussetted side walls (15) may be easily pulled from the stub shaft supports (26) to open the outermost bag in the pack while retaining the rear wall (14) and the rear section of the gussetted side wall (15) of the bag on the stub shaft supports (26) so that the bag is partially held on the rack (25) in the opened position during loading. The additional cut (21) to enlarge the bag mounting apertures (20) in the front wall (13) and front section of the gussetted side walls (15) is formed by cutting against flat plates positioned within the gusset folds of a continuous tube of film during fabrication of the bags. &lt;IMAGE&gt; &lt;IMAGE&gt;</p>
