Abstract: A sealing tool includes an anvil and a horn, at least one of which includes a sealing surface having a gusset sealing section and a zipper sealing section, each configured differently than the other. The gusset sealing section includes a plurality of sealing beads including a gusset section barrier sealing bead having a first height and a protective sealing bead having a second height, the second height being smaller than the first height. The zipper sealing section includes a zipper section barrier sealing bead extending and a tapered section adjacent to the zipper section sealing bead, the tapered section tapering from a larger height adjacent to the zipper section sealing bead to a smaller height as a distance away from the zipper section sealing bead increases.

Abstract: An ultrasonic sealing device, including a horn having a sealing surface, an anvil having a sealing surface, at least one of the horn and the anvil being moveable to engage the respective sealing surfaces, the sealing surfaces of the horn and the anvil including a plurality of protrusions and a recess between each of the protrusions, each of the protrusions having a distal surface and sloped sidewalls with curved edges therebetween and each of the recesses including a recess surface with curved edges, wherein, upon engagement of the sealing surface of the horn with the sealing surface of the anvil, the distal surfaces of each of the protrusions on each of the sealing surfaces engage corresponding ones of the recess surfaces of each of the recesses on each of the sealing surfaces and define gaps between the sidewalls of each adjacent protrusion.
