To provide a packaging container for which whether the container is opened or not opened can be discerned quickly, fear for being opened during transportation is not existent and an excessive cost is not required.

A packaging container 1 is composed of an outer cylinder 2 which is dividable into a cap body part 3 and a main body part 4, an upper and a lower external end walls 16 and 17, an inner cylinder 20 and an upper and a lower internal end walls 21 and 23. The cap body part 3 and the main body part 4 are separably connected together with a relatively weak connecting part 6 and a relatively strong connecting part 7, and a lip part 11 is formed, being incised at the cap body part 3. With the lip part 11 torn away with fingers from the cap body part 3, the strong connecting part 7 is severed by this tearing-away force and with the cap body part 3 and the main body part 4 twisted in the opposite directions thereafter, the weak connecting part 6 is easily severed by the twisting force and both of the parts 3 and 4 are separated, making the packaging container 1 opened.
