Abstract: A lightweight container having a readily removable corrugated sidewall. The inner ply of the sidewall is a corrugated sheet having a selected length and width. A bottom wall member is positioned adjacent the lower axial edge of the inner sheet. A flat outer sheet, of selected length and a width greater than the width of the corrugated inner sheet, is joined to the inner sheet to define the outer ply of the sidewall. The outer sheet projects beyond the lower edge of the inner sheet and is folded against and secured to the bottom wall member, to thereby restrain movement of the bottom wall member. A frangible joint is defined along which the sidewall can be severed from the bottom wall without severing the corrugated inner wall, so that the inner wall adds rigidity without interfering with the ready removal of the sidewall. In the preferred arrangement, the adjacent ends of the inner sheet are in a substantially abutting and unsealed relationship to assist in the opening of the container.

Abstract: The present invention relates to production and packaging of seasoned rice rolled in laver. A laver is fixed on a long strip of packing sheet for blocking the moisture and seasoned rice of cylindrical shape is situated at the center of said packing sheet. The packing sheet is then folded back in order to pack the laver and the seasoned rice separately, preventing the direct contact of them. When eating, said seasoned rice is rolled on the laver by pulling one end of the packing sheet, stripping the seasoned rice which rolls over the laver on the packing sheet. Thus, the flavor of laver can be secured from damage by moisture of said seasoned rice even long after production. In addition, said seasoned rice rolled in laver can be packed surely and cleanly for selling at a drive-in store or at a station.
