JP 2005-320032 A

  The heavy box in FIG. 1 can be efficiently manufactured by providing a folding groove on the inner side of the paperboard, bending it at a right angle, processing it into a quadrangle, and fixing it around the bottom plate 330. However, the heavy box 300 having this structure has a drawback that the heavy box main bodies 310 are stacked and laterally shifted. In addition, the lid 350 that is placed on the upper end opening of the heavy box main body 310 and closes the opening 340 also has a drawback of lateral displacement. This drawback can be solved by using the upper end edge and the lower end edge as a fitting structure. However, in the structure in which the peripheral wall of the paperboard is fixed around the bottom plate, it takes much time to use the upper end edge and the lower end edge as the fitting structure. Further, when the fitting structure is adopted, a step is formed inside the peripheral wall 320, and there is a defect that the stored items are easily attached to the step. Further, since the thick paperboard is bent and manufactured, there is a drawback that it takes time and effort. If the paperboard is made thin, the strength of the peripheral wall is lowered, and there is a drawback that the use is limited.

  The present invention has been developed for the purpose of solving such drawbacks. An important object of the present invention is to provide an Awa Washi paper heavy box that can be stacked in a simple, easy and inexpensive mass production manner so that the heavy box main body can be stacked so as not to be laterally displaced, and the lid can also be stacked so as not to be laterally displaced to the heavy box main body. There is to do. Another important object of the present invention is to provide an Awa Japanese paper heavy box capable of efficiently and beautifully producing a heavy box body while making the peripheral wall thick and having a strong structure.

Means for solving problems and effects of device

  The heavy box of Awa Washi of the present invention has the following configuration in order to achieve the above-mentioned object. That is, an Awa Japanese paper heavy box according to the present invention has a rectangular box shape having an open top and a closed bottom, and a plurality of heavy box bodies 1 stacked in multiple stages, and an opening of the upper heavy box body. 2 is a paper Awa Japanese paper heavy box which is detachably connected to the cover 2 and includes a lid 30 which closes the opening of the heavy box main body.

  The heavy box main body 1 includes a bottom plate 3 having a paperboard made of a square and a side plate 4 which is fixed around the bottom plate 3 and is formed by bending one continuous paperboard into a square. The side board 4 includes an outer paperboard 15 laminated outside and an inner paperboard 5 laminated and fixed inside the outer paperboard 15. The outer paperboard 15 and the inner paperboard 5 have the same vertical width, and are fixed so that the inner paperboard 5 is positioned above the outer paperboard 15. A fitting recess 7 for guiding the fitting ridge 6 is provided on the inside.

  Further, the lid 30 fixes a peripheral wall 32 formed by folding the paperboard into a quadrangle around the top board 31 made of the paperboard as a quadrangle, closes the top, opens the bottom, and has a planar shape. The outer shape is a box shape that is equal to the outer shape of the heavy box body 1. Further, the peripheral wall 32 of the lid 30 is made of a single sheet of paper, and its inner shape is the outer shape of the fitting ridge 6 and its outer shape is the outer shape of the heavy box main body 1. The plurality of heavy box main bodies 1 are laminated so that the plurality of heavy box main bodies 1 can be attached to and detached from each other by guiding the fitting convex stripes 6 into the fitting concave portions 7, and further the fitting convex stripes of the uppermost heavy box main body 1 a. The lid 30 is connected to the outer side of 6 so as to be removable, and the opening 2 is closed.

  By providing said structure, it can be set as the heavy box which can be laminated | stacked so that a heavy box main body and a cover may not slip | deviate laterally. In addition, the heavy box body can be manufactured efficiently and cleanly while making the peripheral wall thick and strong. This is a unique effect obtained by stacking and fixing the outer paperboard and the inner paperboard so that the inner paperboard is positioned above the outer paperboard, and using this as the side board. With this structure, the upper end edge of the side plate can be easily provided with an insertion structure that protrudes upward on the inner side to form an insertion protrusion, and further on the inner side of the lower end edge as an insertion recess that guides the insertion protrusion. it can. That is, the fitting structure can be obtained simply by shifting and fixing the two layers of paperboard without bending the paperboard. Further, since the inner paperboard is located above the outer paperboard, no step is generated inside the box. Therefore, it is possible to avoid the stored items in the box from adhering to the steps.

  Further, another Awa Japanese paper heavy box of the present invention is formed by adhering the surface paper 8 to the surfaces of the heavy box main body 1 and the lid 30. Thereby, since paperboard and the surface paper which coat | covers this are the same materials, both adhesiveness can be improved. Therefore, the surface paper can be efficiently attached to the surface of the heavy box main body and the lid. In addition, by appropriately selecting the surface paper according to the texture, color, pattern, etc., the appearance of the heavy box can be freely changed, and the design and versatility of the box can be enhanced. Also, the outer paper can protect the box body from moisture and damage, and the resistance of the heavy box itself can be improved.

  Further, another Awa Japanese paper heavy box of the present invention is characterized in that the surface paper 8 is Japanese paper.

  Further, another Awa Japanese paper heavy box of the present invention is characterized in that the Japanese paper of the surface paper 8 is dyed with a natural dye.

  Further, another Awa Japanese paper heavy box of the present invention is characterized in that the heavy box body 1 is laminated in three stages.

  Embodiments of the present invention will be described below with reference to the drawings. However, the embodiment shown below exemplifies a heavy box of Awa Washi for embodying the technical idea of the present invention, and the present invention does not specify the heavy box of Awa Washi as follows. Further, in this specification, in order to facilitate understanding of the scope of the utility model registration request, the numbers corresponding to the members shown in the examples are referred to as “utility model registration request scope” and “means for solving the problems and It is added to the members shown in the column of “Effect of device”. However, the members shown in the claims of the utility model registration are by no means specified as the members of the embodiment. Moreover, in the figure, the same name and the code | symbol have shown the member same or the same quality, and abbreviate | omits detailed description suitably. Note that the contents described in some examples and embodiments may be used in other examples and embodiments.

  FIG. 2 is a perspective view of a heavy box of Awa Washi paper (hereinafter sometimes simply referred to as “heavy box”) according to the first embodiment, and FIGS. 3 and 4 are exploded perspective views of the heavy box 100 of Awa Washi paper, respectively. Show. As shown in FIGS. 2 and 3, the Awa Washi heavy box 100 according to the first embodiment is attached to and detached from the heavy box main body 1 having a rectangular box shape with the top opened and the bottom closed, and the opening 2 of the heavy box main body 1. The lid 30 is connected freely and closes the opening 2 of the heavy box body 1. In the example of FIG. 2, the heavy box main bodies 1 are stacked in multiple stages, and are connected in a posture in which the lid 30 closes the opening 2 in the uppermost heavy box main body 1. That is, FIG. 2 shows a state in which a plurality of heavy box main bodies 1 and lids 30 are stacked, and FIG. Further, FIG. 4 is illustrated so that the opening of the heavy box main body 1 is directed downward, that is, a perspective view as seen from the direction in which FIG. 3 is turned upside down.

  As shown in FIGS. 3 and 4, the heavy box main body 1 is formed by a rectangular base plate 3 that is fixed to the periphery of the bottom plate 3, and one continuous paperboard is bent into a quadrilateral shape. It consists of a side plate 4. As will be described in detail later, the side board 4 is configured in two layers from an outer paperboard 15 laminated outside and an inner paperboard 5 laminated and fixed inside the outer paperboard 15 (FIG. 19). reference). The outer paperboard 15 and the inner paperboard 5 have the same vertical width. The inner paperboard 5 is fixed so as to be positioned above the outer paperboard 15. Therefore, the upper protrusion of the heavy box main body 1 is provided with an insertion protrusion 6 (see FIG. 3) that protrudes from the inner side. A fitting recess 7 (see FIG. 4) for guiding 6 is formed.

  As shown in FIGS. 2 and 3, the lid 30 fixes a peripheral wall 32 formed by folding the paperboard into a quadrangle around the top board 31 made of the paperboard as a quadrangle, and closes the top. Open the bottom. Further, the lid body 30 has a box shape in which a planar outer shape is a quadrangle equal to the outer shape of the heavy box main body 1. As shown in FIG. 4, the peripheral wall 32 of the lid 30 is made of a single sheet of paper, and the inner shape thereof is the outer shape of the fitting ridge 6 and the outer shape is the outer shape of the heavy box main body 1.

  That is, as shown in FIG. 3 and FIG. 4, the heavy box main body 1 is laminated so that each of the heavy box main bodies 1 can be attached to and detached from each other by guiding the lower fitting protrusion 6 to the fitting concave portion 7. Further, the lid 30 is connected to the outer side of the fitting ridge 6 of the heavy box main body 1 at the uppermost stage in FIG. 3 (lowermost stage in FIG. 4) to close the opening 2 of the heavy box main body 1. In the present specification, the “uppermost stage” means a stage arranged at the highest position in the stacking direction.

  By the way, in FIG. 2, the heavy box main body 1 of substantially the same size is expressed in three stages. However, if it has said fitting structure, it will not specifically limit about the total number of heavy box main bodies 1, or an internal depth. Any heavy box main body 1 is provided with the fitting structure corresponding to another heavy box main body at the upper end edge and the lower end edge. That is, the heavy box main body 1 can be attached to and detached from the upper or lower stage of the other heavy box main bodies 1, and therefore, the stacking order of the heavy box main bodies 1 can be freely changed without specifying the heavy box main body 1 located at the uppermost stage. On the other hand, not only the uppermost heavy box main body 1 but also the lid 30 is configured to be capable of fitting the fitting protrusions 6 of the middle or lowermost heavy box main body 1. Therefore, any heavy box main body 1 can be arranged in the uppermost stage, and the heavy box main body 1 is connected to the lid 30 so as to be opened and closed.

(Box material)
The heavy box 100 of Awa Washi is made of paper. That is, since it is made of the same paper as the surface paper 8 to be described later, which is coated on the surface of the heavy box, the adhesion between the two is enhanced. Furthermore, the paper can be easily cut, bent, assembled, and the entire box can be lightened. It is relatively inexpensive, easily available, and can be mass-produced. In particular, it is preferable to use a paperboard in which two or more layers of paper-made paper are bonded together, so that a sturdy structure with excellent impact resistance can be obtained despite being lightweight.

  That is, by using paperboard, the overall weight can be reduced while making the box structure more robust. Therefore, transportation becomes easy. In particular, by laminating paperboard on the inside and outside, the structure can be further strengthened. Further, since it is made of paper, it is easy to process such as cutting, bending, and bonding, and therefore, the operation can be simplified and the productivity can be improved. In addition, when it is unnecessary, it can be recovered as paper recycling without incineration, which is preferable because the burden of disposal processing is reduced.

(Surface paper)
In addition, the Awa Japanese paper heavy box 100 of Example 1 has the surface paper 8 bonded to the surfaces of the heavy box main body 1 and the lid 30 constituting the same. The surface paper 8 may be a Japanese paper containing plant fibers, or a synthetic paper that is not limited to plant fibers and is mainly made of synthetic resins such as chemical fibers and films. In Japanese paper, long fibers are closely entangled with each other, so that even if folded or pulled, the entanglement is not easily released and the fibers do not come off. Therefore, even if it is thin, it is strong and has excellent durability. On the other hand, the synthetic paper can enjoy features such as moisture resistance and weather resistance. Further, a processed paper obtained by coating the surface of the paper with a protective film such as a resin, a plastic film, an aluminum foil, or another paper material, and laminating it by heating and pressing may be used. As a result, the paper can be made with various functions such as further improving strength and durability.

  In the heavy box of Awa Japanese paper of Example 1, Japanese paper was used. Specifically, it uses bast fibers such as mulberry, mitsumata, and ganpi as the main raw material, and is boiled with alkali such as wood ash and soda ash to dissolve away impurities. Further, the fibers were loosened and paper was made to obtain Japanese paper. By using Japanese paper, the natural color and luster of the plant fibers as raw materials can be fully exerted, and the design of the box can be enhanced. In addition, Japanese paper is preferable because it has a strong characteristic even if it is thin.

  Furthermore, the paper may be colored with pigments or dyes. The Japanese paper of Example 1 is dyed with natural dyes obtained from plants, animals, and minerals. Specifically, safflower, Taisei (big blue), akane, indigo, cochineal, logwood, and the like can be used. Since coloring with natural dyes has a unique color and texture, combined with the texture of Japanese paper, the design effect is further enhanced. In the paper making process, color loss in refined Japanese paper can be avoided by dyeing plant fibers with natural dyes. Furthermore, compared with the use of synthetic dyes, the environmental burden due to waste liquid in the dyeing process can be reduced, which is preferable. Also, it is preferable to use Awa Washi as Japanese paper because it can be a heavy box that takes advantage of the color and texture of Awa Washi. Furthermore, if you use Awa Washi, dyed with indigo, yellow leaf and Senshu, you can further enhance the design. Below, each member of a heavy box is demonstrated in detail with a manufacturing method.

(Heavy box body)
The heavy box main body 1 includes a box-shaped main body inner side 9 and an outer frame body 10 that covers the outer surface side of the side surface of the main body inner side 9. By bonding the main body inner side 9 and the outer frame body 10, the side plate 4 on which two layers of paperboard are laminated is obtained. Such a two-layer structure of paperboard is obtained as follows.

  First, in order to form the main body inner side 9 with the inner paperboard 5, the inner paperboard 5 is cut into a rectangular shape as shown in FIG. Further, as the surface paper 8 to which the inside of the main body inner side 9 is bonded, the inner surface paper 8a is cut into a square shape. Then, the inner paperboard 5 and the inner surface paper 8a are bonded to form a slip sheet 11 (FIG. 6). The interleaf paper 11 with Japanese paper is punched into a predetermined shape by a planographic punching machine (arrow cut) so as to correspond to the developed view of the heavy box body 1 (FIG. 7). And as shown in FIG. 8, the slip sheet 11 is assembled and it is set as the box shape opened to at least one direction. Furthermore, the main body inner side 9 is obtained by temporarily fixing with a tape or the like so as to maintain the box shape.

  In order to coat the outer surface of the inner side 9 of the main body with the surface paper 8, as shown in FIG. 9, the outer surface paper 8b is pulled out with a pon so as to have a predetermined size. The outer surface paper 8b includes a developed shape of the main body inner side 9, and when the outer surface paper 8b is coated on the outer surface of the main body inner side 9, the outer surface paper 8b has a size that can be folded inward at the end of the opening. . After cutting the outer surface paper 8b, as shown in FIG. 10, with the main body inner side 9 disposed at a predetermined position of the outer surface paper 8b, the outer surface through an adhesive such as glue or bond. The paper 8b is bonded to the outer surface of the main body inner side 9. As a result, as shown in FIG. 11, the outer surface paper 8 b adheres to the outer surface of the main body inner side 9 constituted by the inner paperboard 5. Specifically, the outer surface paper 8b is folded back from the outer surface side of the main body inner side 9 to the inner side of the box through the periphery of the opening 2, and is further attached to a part of the inner surface paper 8a that has already been adhered. Laminated and glued. As a result, almost all of the outer and inner surfaces of the main body inner side 9 are covered with the surface paper, and the lower ground of the paperboard is not exposed. In particular, before assembling the inner paperboard 5, the inner paperboard 5 and the inner surface paper 8 a are used as the interleaf paper 11 in advance, and this interleaf paper 11 is used as the assembly main body 9, thereby greatly reducing the trouble of covering the surface paper. can do. Furthermore, it is preferable that the shape of the box can be adjusted by applying pressure in a direction substantially orthogonal to the bottom plate of the box by passing the inside 9 of the main body through a roller.

  On the other hand, the outer frame body 10 in contact with the side surface of the main body inner side 9 is manufactured as follows. First, as shown in FIG. 12, the paperboard 25 is cut into a square shape. Further, the paperboard 25 is punched into a predetermined shape by a planographic punching machine (arrow cut) so as to correspond to the development of the outer frame 10 (FIG. 13). And as shown in FIG. 14, the slip sheet 11 is assembled and it is set as the rectangular frame body opened to the up-down direction. Further, the outer frame 10 is obtained by temporarily fixing with a tape or the like so as to maintain the rectangular shape.

  Further, as the surface paper 8 to which the outer surface of the outer frame body 10 is bonded, as shown in FIG. 15, the frame surface paper 8c is pulled out with a ounce so as to have a predetermined size. The surface paper 8c for frame includes the developed shape of the outer frame 10, and when this surface paper 8c for frame is covered on the outer surface of the outer frame 10, it is folded back inward at the edge of the outer frame 10. Let it be a size that can be. After cutting the surface paper 8c for the frame, as shown in FIG. 16, with the outer frame 10 disposed at a predetermined position of the surface paper 8c for the frame, through an adhesive such as glue or bond. The frame surface paper 8c is bonded to the outer surface of the outer frame 10 and is wound and pasted. As a result, as shown in FIG. 17, the frame surface paper 8 c sticks the outer surface of the outer frame body 10, and can be folded back inward through the periphery of the outer frame body 10.

  Subsequently, as shown in FIG. 18, the outer surface side of the main body inner side 9 and the inner surface side of the outer frame body 10 are fixed via an adhesive such as glue and a bond to obtain the heavy box main body 1. By the way, the upper and lower widths of the outer paperboard 15 and the inner paperboard 5 are substantially equal. Accordingly, when the inner main body 9 and the outer frame body 10 having the same vertical width are overlapped, the inner main body 9 is shifted and laminated so as to be higher than the outer frame body 10. As a result, as shown in FIG. 19, a two-layer side plate 4 is obtained which is composed of an outer paperboard 15 laminated on the outer side and an inner paperboard 5 laminated and fixed on the inner side of the outer paperboard 15. Further, the inner paperboard 5 is fixed so as to be positioned above the outer paperboard 15, and as a result, the upper end edge of the heavy box main body 1 is provided with a fitting protrusion 6 that protrudes on the inner side, on the inner side of the lower end edge. A fitting recess 7 (see FIG. 4) for guiding the fitting ridge 6 is formed. In other words, in the plan view from the upper surface according to FIG.

  As shown in FIG. 3 or FIG. 4, the heavy box main body 1 manufactured by the above method guides the fitting protrusions 6 of the lower heavy box main body 1 to the fitting concave shape 7, so that a plurality of heavy box main bodies 1 are formed. They are stacked so that they can be detached from each other. This fitting structure will be described in more detail with reference to FIG. 20 is a cross-sectional view taken along line XX-XX ′ in FIG. Each heavy box main body 1 is provided with a level difference 12 caused by a height difference between the main body inner side 9 and the outer frame body 10 at the upper end edge. And the orthogonal | vertical area | region of the baseplate 3 of the upper stage heavy box main body 1 and the outer side frame 10 is connected to this level | step difference 12 in the attitude | position which meshes | engages.

  In other words, the outer surface of the fitting protrusion 6 on the inner side 9 of the main body is guided by the upper fitting recess 7 and contacts the inner surface of the outer frame 10. Furthermore, the upper surface 14a of the outer frame body 10 abuts on the bottom surface 14b of the outer frame body 10 positioned in the upper stage, and connects the upper and lower outer frame bodies 10 to each other. That is, it is the structure which connects the thickness of the outer side frame 10, and, therefore, in the lamination | stacking state of the heavy-box main body 1, the side surface 26 of each outer side frame 10 is located on the substantially same extended surface. Therefore, it is preferable from the viewpoint of stability in the connected state that the protrusion height of the fitting protrusion 6 and the depth of the fitting recess 7 are substantially the same. However, if the depth of the fitting recess 7 is greater than at least the protruding height of the fitting projection 6, the inner surface of the outer frame 10 is in contact with the outer surface of the fitting projection 6 and the upper and lower outer frames 10 are arranged. Since they can be brought into contact with each other and connected, the detachment function of the heavy box body 1 is not hindered.

  Further, in Example 1, Sanyo paperboard 70.5K was used as the paperboard, and Awa hand-made Japanese paper (repellent part paper) was used as the surface paper 8. Furthermore, glue was used as an adhesive between paperboard and Japanese paper. Accordingly, it is preferable because the Japanese paper can be surely covered to every corner of the surface of the paperboard even in an extremely narrow region such as a corner while suppressing uneven adhesion.

(Lid)
Further, a lid 30 that is detachably connected to the opening 2 of the heavy box main body 1 and closes the opening 2 is composed of a paperboard and a surface paper 8 that are the same quality as the heavy box main body 1 described below. It is manufactured as follows. First, as shown in FIG. 21, the cover paperboard 13 is cut into a rectangular shape. Further, as the surface paper 8, the inner surface paper 8a is cut into a square shape. Then, the lid paperboard 13 and the inner surface paper 8a are bonded to form the interleaf paper 11, which is in the state shown in FIG. The interleaf paper 11 with Japanese paper is cut into a predetermined shape by a planographic punching machine (arrow cut) so as to correspond to the developed view of the lid 30 (FIG. 23).

  Subsequently, as shown in FIG. 24, the slip sheet 11 is assembled into a box shape. The lid 30 is obtained by temporarily fixing with a tape or the like so as to maintain the box shape. Further, in order to bond the outer surface paper 8b to the outer surface of the lid body 30, first, as shown in FIG. 25, the outer surface paper 8b is pulled out to a predetermined size. The outer surface paper 8b has a shape similar to the developed shape of the lid body 30, but when the outer surface paper 8b is coated on the lid body 30, the outer surface paper 8b has a size that can be folded inward at the end of the opening. Moreover, as shown in FIG. 25, it is preferable to cut off the corner of the sticking region corresponding to the side plate of the lid 30 in the outer surface paper 8b. This facilitates the process of applying the outer surface paper 8b to the lid 30.

  After cutting the outer surface paper 8b, as shown in FIG. 26, with the lid 30 placed at a predetermined position of the outer surface paper 8b, the outer surface paper is bonded via an adhesive such as glue or bond. The paper 8b is bonded to the lid 30. As a result, as shown in FIG. 27, the surface of the lid body 30 is adhered with the outer surface paper 8b, and more specifically, the inner surface paper is folded back from the outer surface side of the lid body 30 to the inner side. Laminate and bond to part of 8a. As a result, almost all of the outer and inner surfaces of the lid 30 can be easily covered with the surface paper 8, and the lower ground of the paperboard is not exposed. Further, the shape of the lid 30 can be adjusted by pressing the lid in a direction substantially orthogonal to the top plate 31 of the lid, for example, by passing the lid through a roller.

  As shown in FIG. 3, the lid 30 manufactured as described above is formed by fixing a peripheral wall 32 formed by folding a paperboard into a square around the top board 31 made of a paperboard as a square. The lid 30 has a box shape in which the upper part is closed and the lower part is opened, and the outer shape of the planar shape is a square equal to the outer shape of the heavy box body 1 (see FIG. 2). The peripheral wall 32 of the lid 30 is made of a single paperboard. Further, as described above, the lid 30 can be stacked on the heavy box main body 1 to close the opening 2 of the heavy box main body 1, and this will be described in detail with reference to FIG.

  In the stacked state of the heavy boxes, the lid 30 and the heavy box main body 1 positioned on the upper and lower stages are connected to the lid 30 at the upper edge of the heavy box main body 1 as follows. That is, the heavy box main body 1 has a level difference 12 due to a difference in height between the main body inner side 9 and the outer frame body 10. The lower end of the peripheral wall 32 of the lid 30 is fitted into this step. That is, the lid body 30 has the outer shape as the outer shape of the heavy box body 1, and the inner shape of the lid body 30 substantially matches the outer shape of the fitting protrusion 6 of the heavy box body 1.

  In other words, in the stacked state of the heavy box body 1 and the lid body 30, the inner surface of the peripheral wall 32 of the lid body 30 is in contact with the outer surface of the fitting protrusion 6 on the inner side 9 of the heavy box body 1. Further, the bottom surface 14 b of the peripheral wall 32 is in contact with the upper surface 14 a of the outer frame body 10 of the lower heavy box main body 1 to connect the lid body 30 and the heavy box main body 1. That is, the thicknesses of the peripheral wall 32 and the outer frame body 10 having substantially the same plate thickness are in contact with each other. As a result, the outer surface of the peripheral wall 32 of the lid body 30 is substantially the same as the outer surface of the outer frame body 10 of the heavy box main body 1. Located on a plane.

  Further, as described above, the heavy box main body 1 according to the first embodiment is manufactured by separately manufacturing the main body inner side 9 and the outer frame body 10 having substantially the same vertical width, and then laminating them in the vertical direction, thereby stacking two layers. A side plate 4 made of the following paperboard is obtained. As a result, at the upper edge and the lower edge of the heavy box main body 1, steps due to the height difference between the inner and outer paperboards can be easily formed. And by setting it as the fitting structure using this level | step difference, the heavy box which does not slip | deviate laterally in a lamination | stacking state can be obtained quickly and simply. In other words, the heavy box can be efficiently and neatly manufactured while making the peripheral wall of the heavy box main body 1 thick and having a strong structure.

  Furthermore, the heavy box 100 of Awa Washi can be obtained by separately manufacturing the main body inner side 9, the outer frame body 10, and the lid body 30 and combining them. In other words, by changing the surface paper 8 that covers each member, the appearance of the member can be varied in color, pattern, texture, etc., and by combining these, variations due to the appearance of the entire Awa Washi heavy box 100 can be made. While increasing, it can bring about a beautiful decoration effect.

  The Awa Washi heavy box of the present invention can be used as a confectionery box, jewelry box, lunch box, and accessory case.
