In this embodiment, the first force application means is an air blowing means 13 for blowing air at positive pressure to the outside of the film, and the container film 100 is formed into a bulge 102 by blowing compressed air to the outside of the film. The second force applying means is a press device 14, and the blister 101 is formed by pressing the press device 14 against the bulge 102 in the direction of the outside of the film. As shown in fig. 9, the outer clamp 11 is provided with a blow hole 13a, and positive pressure blowing is performed through the blow hole 13 a.

Since the container film 100 is held between the outer and

inner nippers

11 and 12, and the inner nipper 12 is provided with the inner relief groove 121, the adjacent area of the container film 100 in the direction inside the edge of the inner relief groove 121 is pre-stretched during the gradual formation of the bulge 102; meanwhile, the outer clamping plate 11 is provided with the outer avoiding groove 111, and in the process of gradually forming the blister 101, the adjacent area of the container film 100, which is positioned in the inner side direction of the edge of the outer avoiding groove 111, is stretched again, so that the local thickness of the edge part of the formed blister 101 can be relatively improved, and the structural strength is increased.
