PROBLEM TO BE SOLVED: To provide a material which allows preservation of a banana for a long period in a refrigerator.SOLUTION: A material 1 has high airtight degree similar to that of a cold insulation bag for blockage of outside of the material from cool air of a refrigerator, or an inside material has to be a material on which an air layer is generated so that a stored object is not discolored due to contact with other commodity. For facilitating taking in and taking out, a fastener 2 is attached to an insertion port. On a lower side of the fastener (the vicinity of an upper part of the material), plural holes 3 for releasing moisture as a measure to mold, are formed.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】バナナを冷蔵庫にて長期保存させることができる素材を提供する。【解決手段】素材1は外側を冷蔵庫の冷気から遮断するため、保冷袋のように密閉度の高い物にし、又、内側の素材は他の商品とあたって変色しないよう空気の層ができるものにする必要がある。出し入れが簡単になるよう、ファスナー2を出し入れ口に取り付ける。ファスナー(素材上部付近)のしたあたりに、カビ対策として水分を逃がすための穴3を複数あける。【選択図】図2
