To improve easiness of unsealing for a pouch wherefrom contents such as liquid detergent, flavoring, edible oil and the like are poured out by a method wherein an easily unsealable part is provided at a spout at the upper part of the pouch and a nip-off part is provided at the outside of easy-unsealing guide parts connecting to both ends of the easily unsealable part with a distance kept from the boundary of a sealing part forming the spout.

A spout 3 of an easily unsealable pouch is formed, on forming the pouch 1 by sealing films by heat-sealing, by heat-sealing so that the lateral on one side at the upper end of the pouch 1 and a sealing part 2 at the upper part on one side of side edge parts are projected toward the inside and provided, being inclined, at one side of the laterals at the upper part of the pouch 1. An easily unsealable part 4 is provided, extending across the spout 3, while an easy-unsealing guide part 5 is provided, connecting to both ends of the easily unsealable part 4, with a distance kept from the boundary of the sealing part 2 of the pouch 1 and a nip-off part 6 is formed at the outside of the easy- unsealing guide part. The easily unsealable part 4 and the ease-unsealing guide part 5 are formed by piercing or thinning/weakening process comprising of one or more of continuous lines.
