Abstract: This cushioned bag includes a double layer of plastic with longitudinal columns formed therebetween. The columns contain cushioning material such as air. The bag has a tubular outer portion providing an outer wall and an inner portion providing an inner wall and cooperating with the outer wall to define the columns. The inner wall is connected to the outer wall intermediate to the columns. The method of manufacturing the cushioned bag comprises the steps of extruding the outer tubular member, extruding the inner tubular member having castled portions spaced from the outer member, sealing the inner member to the outer member between the castled portions, cutting the tubular members into individual bag lengths, sealing one end of the cut tubular members to provide a closed bottom portion and sealing the other end of the outer tubular member to the castled portions to provide closed upper ends of the castled portions.

Abstract: The invention provides a molded plastic handle for attachment to the upper end of a heavy duty olefin bag for packaging dry mix and the like, wherein the handle is provided with a hand-engaging opening, has an integrally formed depending skirt of alternating depending portions adapted to be sonically or impulse sealed to the outer surfaces of the upper edge portion of the olefin bag, with each of the depending surfaces so arranged that they do not overlap or correspond position-wise to the skirt depending element on the opposite side of the olefin bag, one of the depending portions being disposed midway along the handle, and a vertical strut being provided connecting the handle top portion to such midway depending portion. The invention also provides integrally formed reinforcing ribs at each side of the handle, on front and back faces, with downwardly bifurcated ends which extend to two end skirt portions, and thereby reinforce such end portions to equalize the load stress on the handle and top of the bag.

Abstract: A pail assembly, preferably all plastic, is provided in which a pail has peripherally spaced pail lugs on its side wall adjacent the rim of the pail. The pail lugs have an inclined cam surface at one end and a bearing surface substantially parallel to the rim along a margin remote from the rim. A lid has an internal annular skirt on and integral with it, of a shape and outside diameter complementary to the inside surface of the pail side wall adjacent the rim so that the skirt and pail surface engage one another snugly when the lid is rotated into mounted condition on the pail. The lid has an annular flange integral with it, spaced radially outboardly of the skirt and defining with the skirt a channel having a closed bottom wall and an open mouth. A plurality of peripherally spaced, radially inwardly extending lugs are formed integrally with the flange.
