A dialysis container that contains dialysis agents and is provided to the dialysis site. It can be stably attached to a dialysis machine, and can be efficiently disposed of because it can be reduced in volume after disposal. There is provided a dialysis container having a novel structure in which the dialysis agent can be easily filled and the dialysis agent filling amount can be easily confirmed. In the dialysis container 10 in which the inlet 14 and the outlet 16 are provided on opposite sides to accommodate the dialysis agent 12, the dialysis agent 12 has a hollow structure with a peripheral wall portion 25 formed integrally. A bottle-shaped container 11 that is held in a substantially constant shape before and after storage and has deformation rigidity that is crushed by atmospheric pressure exerted on the outer peripheral surface 39 of the peripheral wall portion 25 by internal decompression is adopted. An inner core member 38 is provided inside the bottle-shaped container 11 so as to be provided between the two opposing sides.透析用剤を収容して透析現場へ提供される透析用容器であって、透析装置へ安定して装着可能であると共に、使用後の廃棄に際して減容することができて効率的に処分可能であり、且つ、透析用剤の充填が容易とされて、透析用剤の充填量の確認も容易に行うことが可能とされる、新規な構造の透析用容器を提供する。 流入口１４と流出口１６が対向する両側に設けられて透析用剤１２を収容する透析用容器１０において、一体形成された周壁部２５を備えた中空構造とされると共に、透析用剤１２の収容前後で実質的に一定形状に保持され且つ内部減圧により周壁部２５の外周面３９に及ぼされる大気圧で潰れる変形剛性を備えたボトル状容器１１を採用し、流入口１４と流出口１６が設けられた対向する両側間に掛け渡される中芯部材３８をボトル状容器１１の内部に設けた。
