PROBLEM TO BE SOLVED: To provide a vessel for infusion solution which includes a medicament vessel having a breakable part and prevents damage to a soft bag by a broken end and a proximal end part during an operation to break the breakable part.SOLUTION: The vessel 1 for infusion solution is equipped with the medicament vessel 3 attached to the soft bag 2. The medicament vessel is equipped with: a medicament vessel body part 5 which has a medicament storing part 54, the breakable part 56, and an operation part 55 for a breaking operation and a cylindrical part 6 which envelopes the breakable part 56 at a distal end part 64. The cylindrical part is equipped with: the diameter-reduced distal end part 64 which envelopes the breakable part and the proximal end part 55a of the operation part and a cylindrical and flexible envelopment part 63 which envelopes the diameter-reduced distal end part, extends beyond the distal end thereby to envelope the proximal end part of the operation part, that is exposed from the diameter-reduced distal end part, and restricts contact with the inner surface of the soft bag by the broken end 55b of the breakable part and the proximal end part 55a of the operation part during the breaking operation by the operation part.COPYRIGHT: (C)2012,JPO&INPIT【課題】破断可能部を有する薬剤容器を備え、破断可能部の破断操作時における破断端および基端部による軟質バッグへの損傷付与が防止された輸液用容器を提供する。【解決手段】輸液用容器1は、軟質バッグ2に取り付けられた薬剤容器3を備える。薬剤容器は、薬剤収納部54、破断可能部56、破断操作のための操作部55を有する薬剤容器本体部5と、破断可能部56を先端部64において被包する筒状部6とを備える。筒状部は、破断可能部および操作部の基端部55aを被包する縮径先端部64と、縮径先端部を被包し、その先端を越えて延び、縮径先端部より露出する操作部の基端部分を被包し、操作部の破断操作中の破断可能部の破断端55bおよび操作部の基端部55aの軟質バッグの内面への接触を規制する筒状可撓性被包部63を備える。【選択図】図12
