PROBLEM TO BE SOLVED: To rapidly perform a triangular rice ball package finishing process with a sheet-like film for rolling a sheet of laver in a single process. SOLUTION: Upper and lower faces 1' or the like and respective sides 1a of a shaped triangular rice ball 1 are packaged with a rectangular packaging film 2, and while both corners 2',2" of the film 2 are protruding above the upper face 1' along the both isosceles-triangular sides 1a, 1a of the rice ball 1, a triangular frame 3 for fitting three sides 1a of the rice ball 1 are provided on a bottom plate, a V-shaped cut reciprocatingly sliding plate 4 for folding both corners which can be reciprocatingly slid along a center line (c) passing through a vertex and a base of the triangular frame 3 is provided, and through holes 5 for inserting a film heat-sealing rod are opened at both sides of the V-shaped cut 4' of the slide plate 4. A center line c' of an open angle of the cut 4' and the center line (c) of the triangular frame 3 are provided in parallel to each other and at slightly shifted positions. |
