PROBLEM TO BE SOLVED: To provide a cylindrical bag body for squeezing a soft viscous body formed only of a plastic or the like, capable of acquiring inexpensively a high-quality material, not having cost reduction caused by erroneous production, capable of squeezing simultaneously and equally many fine flows of the soft viscous body, and capable of performing efficiently with a small squeezing power, a work for forming a beautiful character or pattern which cannot be obtained hitherto, while adding thereto liking or creativity of an operator.SOLUTION: A cylindrical bag body 1 is formed by superposing each laminated plastic film having a plastic base material film as an outer layer and a heat-sealable plastic film as an inner layer followed by heat-sealing of its peripheral part. A plurality of opening scheduled parts 6, 6... from which a soft viscous body loaded in the bag body is extruded are prepared on the tip part of the bag body 1, and formed so that each extrusion amount from the plurality of opening scheduled parts 6, 6... becomes equal. |
