PURPOSE: To accurately measure the quantity of liquid to be added to a concentrated product by providing a gusset panel on a bottom part of a pouch, fixing its edge to an inner surface of a side panel, and folding a central portion of the gusset panel to be freely and upwardly extended to the inside of the pouch.
CONSTITUTION: A pouch 10 includes the flexible side panels 12, 14, these panels are laminated one another and mutually sealed or thermally adhered along the side edges 16, 17 to form the side seals 18, 19, and they are closely contacted along an upper edge 20 to form an upper seal 21. The bottom edges 22, 24 of the panels 12, 14 are adhered to one another to form a bottom seal, whereby a closed pouch structure is completed. A gusset panel 26 portion upper than the seal lines 28, 30 are not attached to the inner surfaces of the panels 12, 14, and a central potion 32 of the gusset panel 26 is freely extended inside the pouch 10 in a folded state.
