<p><P>PROBLEM TO BE SOLVED: To provide a packing bag for a liquid, powder, or granule, which is simple in structure, and an opening part becomes a funnel shape by ripping an end part of the packing bag so as to spill the content less in use. <P>SOLUTION: Bag bodies 1, each including a hollow part of an isosceles triangle shape with a sealed peripheral edge, is arranged and joined in a band shape so that bases of isosceles triangles of the adjacent bag bodies 1 oppose to each other. A separating means such as a perforated line is formed in a joined part 3 of the bag bodies 1. A rip assisting means such as a notch or slit is formed near an apex of the isosceles triangle of the sealed part 2 so that the opening part does not become wider than needed when the bag is ripped. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
