The present invention provides a packing inside bag for a semisolid viscous material which is constructed by folding one rectangular blank sheet an inner surface of which has release properties, said inside bag being characterized by comprising a rectangular bottom surface 1 formed so as to fit to an outside box, and a front wall 3, a rear wall 3a and pairs of side walls (8, 8a and 9, 9a) which are uprightly raised along the four side edges of said bottom surface 1, said inside box being constructed by folding said blank sheet so that first lugs A, A′extending uprightly along the centers of said side walls may be put on said opposite side walls, and so that second lugs B, B′may be formed which are composed of irregular quadrilaterals extending outward via folds 4, 5 in parallel with said bottom surface from the opposite side edges thereof, said irregular quadrilaterals being formed by putting triangle portions D, D′on extensions C, C′of said first lugs A, A′.

A packing inner bag suitable for retaining therein a semisolid viscous material and suitable for fitting within an outer box, said bag comprising: an integral rectangular blank sheet having an inner surface coated with an agent having release properties, said sheet being folded to form said bag with a plurality of walls including: a bottom wall sized to fit in said box, said bottom wall having a front edge, a rear edge opposite said front edge, a left edge, and an oppositely located right edge; a front wall extending uprightly from said front edge, a rear wall extending uprightly from said rear edge; a left wall adjoining said left edge, said front wall and said rear wall; a right wall adjoining said right edge, said front wall and said rear wall; said bottom, front, rear, left and right walls defining an interior of said bag therebetween; each one of said left and right walls respectively including a first wall portion folded from said front wall and extending towards said rear wall, a second wall portion folded from said rear wall and extending toward said front wall, said wall portions being long enough to meet at an uprightly extending center of said left or right walls, a first extending away portion continuing from said first wall portion and a second extending away portion continuing from said second wall portion, said first and second extending away portions extending away from said bag and overlapping one another without adhering to one another to form respectively a left lug at said left wall and a right lug at said right wall, the transverse dimension of said lugs measured in a direction parallel to the plane containing said bottom wall being long enough to seal said viscous material in said bag; each one of said lugs being folded once along the upright longitudinal center to abut its respective left or right wall, without being folded onto itself.
