ABSTRACT:
An ultrasonic sealing apparatus is disclosed wherein a pair of sheet-like members a bottom portion of a tubular member is fuse-bonded together by frictional heat generated by ultrasonic vibration. The apparatus includes horn (1) and anvil (2) means interposed with members to be fuse-bonded together. The horn and anvil provide contact surfaces (3) in contact with the members to be fused. Each of the contact surfaces is formed with a plurality of grooves (4) to provide a plurality of protrusions (5). Each of the protrusions has a flat upper surface and slanted side surfaces (6), so that the protrusion has a trapezodial cross-section. The horn means applies ultrasonic vibration to the fuse-bonding surfaces of the members to be fused in a direction oblique or parallel therewith in association with the anvil means.
