发明名称 SMALL BAG WITH POURING PASSAGE
摘要 PROBLEM TO BE SOLVED: To provide a small bag having a pouring passage of superior applicability in which a hand and fingers or the like are not stained with stored contents when the bag is opened, the stored contents are not flowed out of the bag even if the small bag is laid during its pouring operation and a separate discharging of the contents can be carried out well. SOLUTION: A small bag 300 having a pouring passage is formed in a three- side seal manner, for example. After charging the bag with liquid contents, an upper opening section is heat sealed in a seal pattern of an upper heat seal section 4 capable of forming a narrow width pouring passage 5, and both surface films of the pouring passage 5 are provided with some spot-like protrusions or indentations 8 fitted to each other under application of an embossing method with a temperature condition in which the inner surfaces of the film are not thermally adhered to each other.
