PURPOSE:To bring a lower case and an upper case to the same shape, to facilitate the control of parts by reducing the kinds of the parts and to achieve cost reduction, by applying taper to both end surfaces of a buffering material so as to make the upper side thereof shorter than the lower side thereof. CONSTITUTION:Taper is applied to the front and back surfaces of each of buffering materials 8 so as to make the width of the upper side thereof smaller than that of the bottom side thereof. A product 7 is received in a lower case 9 after the buffering materials 8 are mounted to said product 7 and an upper case 10 is combined with the lower case 9 so that the front and back side panels thereof are overlapped with those of the lower case 9, and a band 11 and a tape 12 are applied to both cases to complete packing. The taper corresponding to the thickness (t) of the cases is provided to both surfaces of each of the buffering materials 8. That is, each of the buffering materials 8 is formed into a shape so that the dimension of the upper side thereof becomes a-2t if the dimension of the lower side thereof is (a). When the buffering materials 8 having the above-mentioned dimension and shape are used, the outer dimension of the upper part becomes a-2t+2t=a in such a state that the lower case 9 is combined with the buffering materials 8. That is, the inner dimension of the upper case 10 becomes exactly equal to that of the lower case 9 and the lower and upper cases 9, 10 can be brought to the same dimension and shape.
