FREEZING PRESERVATION CONTAINER, CONTENT-CONTAINING CONTAINER, MANUFACTURING METHOD OF FREEZED CONTENT, AND MANUFACTURING METHOD OF CONTENT

To provide a freezing preservation container capable of preventing a cylindrical body from being peeled from a container body when being frozen while suppressing influence on a content exerted by the cylindrical body.SOLUTION: A freezing preservation container 10 comprises: a first outer peripheral part 12; a second outer peripheral part 14; a recess 13, at least part of which is located on an inner side of the first outer peripheral part and the second outer peripheral part when being projected in parallel on a horizontal plane perpendicular to a central axis, that is located between the first outer peripheral part and the second outer peripheral part; and a cylindrical body 20 arranged in a non-adhesion state with respect to the recess. Even if the cylindrical body is deformed or moved in any way, when being projected in parallel on the horizontal plane, at least part of an inner periphery of the cylindrical body is located on an inner side of an outer periphery of the first outer peripheral part and an outer periphery of the second outer peripheral part.SELECTED DRAWING: Figure 1 【課題】筒状体による内容物への影響を抑制するとともに、凍結した際に筒状体が容器本体から剥離することを抑えることが可能な、凍結保存用容器を提供する。【解決手段】凍結保存用容器１０は、第１外周部１２と、第２外周部１４と、第１外周部と第２外周部との間に位置し、中心軸に垂直な水平面に平行投影したときに、少なくとも一部が第１外周部及び第２外周部よりも内方に位置する凹み部１３と、凹み部に対して非接着の状態で配置された筒状体２０と、を備え、筒状体をどのように変形又は移動しても、水平面に平行投影したときに、筒状体の内周の少なくとも一部が第１外周部の外周及び第２外周部の外周よりも内側に位置する。【選択図】図１
