が小さいという欠点がある。 Conventionally, when superimposing laminated films and performing ultrasonic fusing, a flat ultrasonic horn 1 was used as shown in Figure 1.
The laminated films to be bonded are stacked between the base plate 2 and the flat lower pedestal 2, and pressure is applied while applying ultrasonic waves to a horn to bond the laminated films by heat. The cross section of the joint in this case is shown in FIG. However, with this method, if material 3 and material 4 are a combination of materials that do not fully fuse together, even if ultrasonic welding is performed, they will not be fused at all, or even if they are fused, the mechanical It has the disadvantage of low strength.

超音波融着方法を提供するものである。 The present inventors have arrived at the present invention as a result of intensive research to find a joining method that eliminates these drawbacks and provides greater mechanical strength to the joined portion. That is, in the present invention, on a base film having heat-fusible properties,
In the ultrasonic welding method for laminated films, in which laminated films are laminated with layers of materials that are difficult to fuse with the base film, the laminated films are overlaid and fused. Laminated films are stacked so that the two material layers are in contact with each other, and the back of the other base film is placed in contact with the other base film. The present invention provides an ultrasonic welding method for laminated films, characterized in that base films are welded together by applying an ultrasonic wave.

FIG. 3 shows an embodiment of the fusion method of the present invention, in which 3 indicates a base film with heat fusion properties, 4 indicates a material layer that does not sufficiently fuse with 3; I don't mind. As shown in Figure 3, the lower pedestal 2' is made uneven and pressure is applied while applying ultrasonic waves.The unevenness of the lower pedestal causes 3 to break through the layer 4 and the 3 to be fused together. Sufficient mechanical strength was obtained at the joint. The cross section of the joint in this case is shown in FIG. 4, where a is a cross-sectional view in the vertical direction (perpendicular to the plane of the paper in FIG. 3) and b is a cross-sectional view in the horizontal direction (parallel to the plane of the paper in FIG. 3). The thickness of the film to which the bonding method of the present invention is applied is preferably 6 to 200 μm. Further, the unevenness may be provided on the horn instead of the lower pedestal, or may be provided on both the horn and the lower pedestal.
