PURPOSE: To easily open a bag for a rice ball with laver by a method wherein the bag with an opening is made up of two films that face each other, an extended part is extended from the upper edge of one of the films beyond the upper end of the other film, joint parts are provided along the side and bottom edges of the films, and cutting lines are made at a level out time films, where the vertex of the rice ball is located, along the width of the opening. CONSTITUTION: Nearly trapezoid two films 12 and 13 are neatly laid on top of the other to form a bag. An extended part 14 is extended from an upper edge 16 of the film 13 beyond an upper edge 15 of the film 12, joint parts 20 and 23 are respectively provided along bottom edges 18 and 19 and side edges 21 and 22 of the films 12 and 13, and an opening 17 is formed along the upper edges 15 and 16. A rice ball with laver is introduced into the bag through the opening 17 with its base down. A cutting lines 27 are made at a level on both films 12 and 13, where the vertex of the rice ball is located, along the width of the opening 17. The bag is easily opened by tearing it along line cutting lines 27 so that the bag is divided into the upper and lower parts. |
