Stable support for can be achieved.

As the above-described first fixed body forming step and the second fixed body forming step proceed in sequence, the fixing part 110 and the sealing part 120 are integrally formed, and then the lead portion 14 of the infusion container 10 is formed. The end of the fixing part 110 is bonded to each other by heat fusion or high frequency fusion.

The inner cover 130 is a plate-like component that covers the outer surface of the sealing part 120 and is coupled to the fixing part 110 in order to prevent external exposure of the sealing part 120. As shown, it may be configured to include a break 132, a through hole 134 and a fastening protrusion 136.

As described above, the breaker 132, the through hole 134, the fastening protrusion 136, and the like may be formed of polyethylene, polypropylene, polystyrene, or the like, which is a hard synthetic resin. It may be integrally formed in the process of molding the inner cover 130 by injecting a thermoplastic resin, such as polycarbonate, or a mixed resin thereof. (First cover forming step)

The breaking portion 132 has a minimum outer portion of the sealing portion 120 (specifically, the central portion of the recess 122 through which the infusion needle 20 penetrates) when the outer cover 140 is removed. As a component provided on one side of the inner cover 130 to be exposed to, it is made to be separated from the inner cover 130 by breaking, ie, torn or broken by an external force.

That is, the break portions 132 (130, 130 '), as shown in Figures 2 and 3, may be a structure including a cover plate 132a, support teeth 132b and the second penetration bar (132c) and the like.
