When the first coupling hole 40 of the cylinder 10 and the second coupling hole 140 of the supply cap 100 are coupled to each other as described above, The supply cap 100 containing the second material B is integrally coupled.

In this state, since the shielding film 200 is not opened, the syringe can be kept in the standby state, and the cylinder 10 and the supply cap 100 are combined with one body, And so on.

5, when the second material B accommodated in the supply cap 100 and the first material A accommodated in the cylinder 10 are mixed, the first and second materials B and C of the cylinder 10 are mixed with each other. And the second coupling hole 140 of the supply cap 100 is coupled in the second direction while rotating in the locking direction.
