PROBLEM TO BE SOLVED: To provide a bag for a liquid nutritional supplement for quickly and reliably confirming the content and the remaining amount of a liquid nutritional supplement in a soft bag visibly at first glance.SOLUTION: A bag 1 for a liquid nutritional supplement includes a soft bag 10 which comprises a surface side film 10a and a rear side film 10b facing the surface side film for enclosing a liquid nutritional supplement and an outflow port 3 provided in a lower end part of the soft bag. The surface side film 10a has a transparent part 12 for visibly confirming the liquid nutritional supplement, and the rear side film 10b has an indicator 13. The indicator 13 is configured to confirm a position of a liquid level of the liquid nutritional supplement corresponding to the content and/or the remaining amount of the liquid nutritional supplement since the indicator 13 is concealed by the liquid nutritional supplement when being confirmed visibly from the transparent part 12 or is visibly confirmed through the liquid nutritional supplement from the transparent part 12. On the transparent part 12, a scale 14a showing the content and/or the remaining amount of the liquid nutritional supplement is provided, and the scale 14a is provided to oppose to the indicator 13.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】ソフトバッグ内の液状栄養剤の容量や残量を、一見して速やかにかつ確実に視認できる液状栄養剤用バッグを提供する。【解決手段】液状栄養剤用バッグ1は、表側フィルム10aとこれに向き合った裏側フィルム10bとからなり、液状栄養剤が封入されるソフトバッグ10と、それの下端部に設けられた流出ポート3とを有するものであり、表側フィルム10aは、液状栄養剤を視認できる透明部分12を有し、裏側フィルム10bは、インジケータ13を有し、インジケータ13は、透明部分12から視認されたときに液状栄養剤に隠蔽され、又は透明部分12から液状栄養剤を介して視認されることで、液状栄養剤の容量及び/又は残量に応じた液状栄養剤の液面の位置を確認することができるものであり、透明部分12には、液状栄養剤の容量及び/又は残量を示す目盛14aが付されており、目盛14aはインジケータ13に対向して設けられている。【選択図】図1
