Integrally serially connected top fillable bags have closed bottoms and sides and reclosable zippers from which pull flanges extend upwardly. The bags are separated along their sides including the pull flanges and continuous connecting strips connect the tops of the pull flanges and have guide ribs extending continuously therealong for engagement by supporting jaws which serve to open the serially connected bags one at a time at a filling station for filling. After the filling station, the filled bag is separated from the connected bags by removing the connecting strip from the tops of the pull flanges of the filled bags in line with or below the top ends of the separations between bags. The zipper of the filled bag is closed by a closing device such as pinch rolls through which the bag is pulled and the connecting strips removed.
Integrally serially connected top fillable bags wherein each bag has closed bottom and side edges and reclosable zipper means extending across the top of each bag with upstanding front and rear pull flanges extending above said zipper means, and comprising:
Connected bags according toclaim 1, wherein said ribs are of square cross-section.
A method of filling and separating top fillable serially conected bags which are closed along their bottom and sides and have reclosable zippers along their upper end portions with front and rear pull flanges extending above the zippers, the bags being partially separated from one another along their adjacent sides by separations, which extend upwardly past said zippers and to the tops of the pull flanges and between the ends of the pull flanges, there being respective continuous integral strips connecting said tops of said front and rear pull flanges and thereby connecting the bags to one another in series, the upper portions of the connecting strips having cohtinuous protruding guide ribs therealong for supporting the connected bags, the method comprising:
Apparatus for filling and separating serially connected top fillable bags which are closed along their bottom and sides and have reclosable zippers along their upper end portions with front and rear pull flanges extending above the zippers, the bags being separated from one another along their adjacent sides by separations which extend upwardly past the zippers and to the tops of the pull flanges and between the ends of the pull flanges, there being respective continuous integral strips connecting said front and rear pull flanges and thereby connecting said tops of the bags to one another, the upper portions of the connecting strips having continuous protruding guide ribs therealong for supporting the connected bags, the apparatus comprising:
