Abstract

A sheet material container (C) includes a containing portion (10a) that contains contents (96) and is formed of a layer sheet (120). The layer sheet (120) includes an inner sheet (123), an intermediate sheet (122) covering an outer side of the inner sheet (123), and an outer sheet (121) covering an outer side of the intermediate sheet (122), and is arranged on opposite sides with the containing portion (10a) between the opposite sides. At least parts of the outer sheet (121) and the intermediate sheet (122) include light transmitting portions (34a, 34b, 34c) that can transmit visible light. The inner sheet (123) or the contents (96) can be visually recognized through the light transmitting portions (34a, 34b, 34c) from outside the sheet material container (C).

First claim

The invention claimed is:

at least parts of peripheral edges of the inner sheet are attached so that the inner sheet forms an inner bag,
the outer sheet and the intermediate sheet have attached portions partially attached to each other and non-attached regions not attached to each other,
a filled portion enclosing a filler is formed between the outer sheet and the intermediate sheet in the non-attached region,
at least parts of the outer sheet and the intermediate sheet include light transmitting portions that can transmit visible light,
the light transmitting portions in the outer sheet and the intermediate sheet have portions overlapping each other when seen from outside the sheet material container, and
the inner sheet or the content is visible through the light transmitting portions from outside the sheet material container.

2. The sheet material container according to claim 1 , wherein a part of the inner sheet is separable from the intermediate sheet.

3. The sheet material container according to claim 1 ,
wherein a part of the inner sheet is separable from the intermediate sheet, and
a volume of the inner bag increases or decreases according to an amount of the content held.

4. The sheet material container according to claim 1 , wherein the light transmitting portion is an opening provided in the outer sheet and the intermediate sheet.
