A seam allowance 228 is continuously provided via 27. The seam allowance 228 is connected to the seam allowance 204 via a fold 229. A fold 230, a pair of holes 231 and a slit 232 are provided in the first, second, fourth, and fifth upper outer peripheral wall portion constituent parts 224 ′ from the left, and the third and sixth upper outer peripheral parts are provided. Only the hole 231 is formed in the wall portion 224 '.

In order to assemble the outer container deploying member having the above-described configuration, the intermediate inner peripheral wall portion 205 is bent upward (valley fold) in the drawing by the fold line 206, folded on the outer peripheral wall portion 201, and then the inner peripheral wall portion is folded. The portion 213 is bent downward (mountain fold) by the fold line 214 and is overlapped with the intermediate inner peripheral wall portion 205. At this time, the engaging tongue receiving windows 212 and 217 are overlapped with each other to form one receiving window (FIG. 12).

Next, the lower inner peripheral wall portion 218 is bent upward (folded into valleys) by the folds 219 to be superposed on the lower portion of the inner surface of the inner peripheral wall portion 213, and the lower innermost peripheral wall portion 221 is formed by the folds 222. It is bent downward (folded into a mountain) and overlapped with the inner surface of the lower inner peripheral wall portion 218. In this state, the upper edge (fold 222) of the lower inner peripheral wall portion 218 and the lower innermost peripheral wall portion 221 which are overlapped with each other coincides with the lower edge of the engaging tongue receiving window 212 (217), or It is arranged slightly above (FIGS. 13 and 14).

The container material 200 folded as described above is bent into a hexagonal tubular shape along the folds 202, 203, 208, 215, 223, 226, 227, and the engagement piece 211 and the insertion piece 209 are provided on the outer peripheral wall. Inserted from one side edge between the portion 201 and the intermediate inner peripheral wall portion 205, the engaging piece 211 is fitted in the fitting opening 205a, and the margins 204, 228 are arranged on the outer peripheral wall portion 201 'on the opposite side and the upper portion. It is attached to the outer surface side edge of the outer peripheral wall portion constituting portion 224 '.

In this state, the minimum inner dimension of the hexagonal outer container (the inner dimension of the lower innermost peripheral wall portion 221) is slightly larger than the outer dimension of the outer peripheral wall of the inner container 1, that is, the inner container 1 The thickness of the engaging tongue piece 32 protruding obliquely downward from the outer surface of the outer peripheral wall portion 2 is selected to be large.

Further, the relative dimensions and positions of the respective constituent parts, windows, engagement openings, notches, folds, etc. are selected so that the above-mentioned folding and assembling is possible. Further, the height positions of the engaging tongue receiving windows 212, 217 from the bottom edges (folds 206, 219) are such that the inner tongue 32 is fitted into the receiving tongues 212 by fitting the inner container as described later. When engaged with (217), the bottom edge of the inner container coincides with the bottom edge of the outer container (hence the bottom surface (bottom plate 100) of the inner container 1 serves as a raised bottom).

It is also possible to adhere decorative paper, cloth, or woven fabric to the outer surface of the outer container.

When the inner container 1 is inserted into the bottom opening of the outer container 200 assembled as described above from above, the engaging tongue piece 32 protruding from the outer peripheral wall of the inner container is the innermost peripheral wall below the outer container 200. The engaging tongue piece 32 is pushed by the inner surface of the portion 221 and slides upward along this inner surface, and when the lower edge of the engaging tongue piece 32 exceeds the upper edge (fold 222) of the lower innermost peripheral wall portion. Spreads slightly outward and engages with the engaging tongue receiving window 212 (217). When the inner container is returned slightly downward from this state, the engaging tongue 32 fits into the receiving window inside 212 (217), so the engaging tongue 32 serves as a detent and the inner container is pulled out downward. It will not be possible. As described above, in this state, the bottom edge of the outer container and the bottom edge of the inner container are aligned with each other, and the bottom surface (bottom plate 100) of the inner container is located above this bottom edge (becomes a raised bottom) (FIG. 16).

The inner and outer containers are suitable for use as a urn container. In this case, the upper outer peripheral wall component portion 224 'of the outer container is bent along the folds 225 and 230, the upper portions of these component portions are gathered together, and the string is inserted into the hole 231 in advance and fastened, The inner container containing the urn is inserted through the bottom opening of the outer container and the two containers are joined as described above (FIG. 17).

At least one engaging tongue 32 and corresponding receiving window 212 (217) may be provided, and the number thereof is arbitrary.

The upper structure of the outer container can be variously modified. For example, it is possible to provide the upper outer peripheral wall portion 224 with no folds 230, holes 231, and slits 232. In this case, the upper outer peripheral wall portion 224 is integrated with the outer peripheral wall portion 201. A lid may be provided on the upper outer peripheral wall 224 or above the outer peripheral wall 201 without forming an opening. It can be used in addition to the urn container.

The outer bottom plate 100 and the inner bottom plate 110 may be integrally formed with the base material of the inner container as shown in FIG.

Although the inner container and the outer container are hexagonal cylinders in the illustrated example, they may be polygonal cylinders other than triangular. Further, it is not limited to the regular polygonal cylinder. As long as the two can be fitted together as described above, the height and diameter of both containers can be freely selected.

FIG. 19 shows a configuration in which only the above inner container is used alone. In this configuration, the intermediate inner peripheral wall portion 3 and the inner peripheral wall portion 4 are removed from the configurations of FIGS. 1 to 10 and the outer peripheral wall portion 2 is not provided with the slit 21. In FIG. 19, the constituent parts corresponding to those in FIG. 1 to FIG. 10 are indicated by the same reference numerals, so that the structure can be easily understood, and the description thereof will be omitted. Also, the assembly method can be easily inferred from the above description, so the description will be briefly stopped.

That is, the (lower) inner peripheral wall portion 5 is folded (valley-folded) at the folds 30 and folded over the inner surface of the outer peripheral wall portion 2, and the (lower) folded inner peripheral wall portion 6 is bent at the folds 60. (Mounting is performed) and the inner wall 5 is folded on the inner surface, and the bottom plate position defining piece 7'is folded at a right angle with respect to the folded inner wall 6 by the fold line 70. From this state, the container material is bent into a hexagonal tubular shape by the folds 20, 51 and the notch 51a, and the seam allowance 2a is bonded and adhered to the inner surface of the outer peripheral wall constituting portion 2'of the right end, and the uppermost folded innermost peripheral wall piece 8'is formed. Are bent inward (folded into mountains) at the folds 80 to be joined to the inside of the outer peripheral wall portion 2, the bottom plate 100 is fitted from the outside of the bottom surface of the container, and the inner bottom plate 110 is fitted into the container. To complete. The outer bottom plate 100 and the inner bottom plate 110 may be integrally formed with the base material as in the configuration shown in the figure. The heights of the inner peripheral wall portion 5 and the folded back inner peripheral wall portion 6 are not limited to the illustrated examples, and may be higher (or the same degree as the outer peripheral wall portion 2).

The container shown in FIG. 19 may be used alone or as a flat lid having the same bottom shape (hexagon in the illustrated example), or a container having the same shape and slightly larger dimensions may be used as the lid. .

The container shown in FIG. 19 may have a polygonal shape other than the hexagonal shape, like the container described above.
