BAG BODY HAVING DIAGONAL SEAL PART, AND SEALING DEVICE OF THE BAG BODY

摘要

PROBLEM TO BE SOLVED: To appropriately regulate the size of an outlet according to the characteristic of the content in a bag body to form the outlet through the diagonal cutting from a seal part to an adjacent side edge by setting the seal angle relative to the adjacent side edge of the seal part according to the content. ;SOLUTION: Side edges 12, 13 and a bottom side 14 of a bag body 1 are sealed, the fluid content is filled in the bag body in a condition where a diagonal seal part 11 is opened, and the diagonal seal part 11 is thermally fused. The diagonal seal part 11 is fused on one adjacent side edge 12 at the seal angle θ1 which is appropriately set according to the characteristic of the content, e.g. the viscosity. When the content is taken out of the bag body 1, the θ1 side forming an acute angle is diagonally cut when the viscosity of the content is small. The outlet is thus lower and the content is difficult to overflow. On the other hand, when the viscosity of the content is high and the content is difficult to flow, the θ2 side forming an obtuse angle is diagonally cut. The content can thus be taken out in a short time.;COPYRIGHT: (C)1999,JPO
