Description

本発明は、紙製重箱の技術に関し、より詳細には、一つ又は複数の身部を有してなり、最上段の身部の開口端に蓋部が印籠嵌合される紙製重箱に関する。 The present invention relates to a technique for a paper jubako, and more particularly to a paper jubako that has one or more body parts, and in which a lid part is fitted into the open end of the uppermost body part. .

従来、仕出しやおせち料理等の調理した料理を収容するための容器や、菓子や葉巻等の贈答向け商品を収容するための容器として、一つ又は複数の身部を有してなり、最上段の身部の開口端に蓋部が印籠嵌合される重箱が多く用いられている。この種の重箱は、化粧箱としての清潔感や高級感が求められることから木製のものが多く用いられてきたが、近年では、質感が木製のものにも劣らない紙製のものも提案されるようになっている。 Conventionally, containers have been used as containers for storing cooked food such as catered meals or New Year's dishes, or for storing gift products such as sweets and cigars, and have one or more bodies. Jubako, in which the lid is fitted into the open end of the body, are often used. This type of jubako has traditionally been made of wood because it is required to have a clean and luxurious feel as a gift box, but in recent years, paper-made boxes with a texture comparable to wooden ones have also been proposed. It has become so.

従来の紙製重箱としては、例えば、特許文献１に開示されるように、側板及び底板にて形成される外箱と、上面開放した状態の外箱の内側に固定され、開口端にて上端部が上方に突出される内枠体とを具備してなる構成が提案されている。かかる紙製重箱では、長尺状の原紙の上下端部をＶ字状の折曲溝に沿ってそれぞれ内側に折り畳み、さらにその左右端部をＶ字状の折曲溝に沿って角環状に折り曲げて形成される側板が用いられることで、角が立った溝の無い外観の重箱を得ることができ、質感に優れた仕上がりとすることができる。 For example, as disclosed in Patent Document 1, a conventional paper heavy box has an outer box formed of side plates and a bottom plate, and is fixed to the inside of the outer box with the top surface open, and the upper end is fixed at the open end. A structure has been proposed that includes an inner frame whose portion projects upward. In such a paper box, the top and bottom ends of a long base paper are folded inward along a V-shaped folding groove, and the left and right ends are folded into a rectangular ring along the V-shaped folding groove. By using side plates formed by bending, it is possible to obtain a multi-box with an appearance without sharp corners and grooves, and a finish with excellent texture can be obtained.

しかしながら、上述した従来の紙製重箱の構成では、外箱において側板の下端部に底板を嵌合させて組み付けるものであったため、底板の取付強度が低く耐久性に劣るとともに、側板に底板を組み付ける際に余剰の接着剤が漏出してしまい外観品質を損なう場合があった。また、近年では製品の価値を高める主な要素の一つとしてデザインの重要性が高まっているところ、従来の紙製重箱の構成では、底板を近傍位置に形成された底板取付溝に嵌合させるものであったため、外箱において底板を側板の下端面と下面とが同一平面上に位置するように取り付けることが困難であり、バリエーションが限定され、新たなデザインニーズに応えることができないという問題があった。 However, in the structure of the conventional paper heavy box described above, the bottom plate is assembled by fitting it to the lower end of the side plate in the outer box, which results in low attachment strength of the bottom plate and inferior durability. In some cases, excess adhesive leaked out, impairing the appearance quality. In addition, in recent years, the importance of design has increased as one of the main factors that increases the value of products, and in the conventional structure of paper-made jubako, the bottom plate is fitted into a bottom plate mounting groove formed at a nearby position. Because of this, it was difficult to attach the bottom plate to the outer box so that the lower end surface of the side plate and the lower surface were located on the same plane, which limited variations and made it impossible to meet new design needs. there were.

以上のように、本実施例の紙製重箱１は、複数の身部２・３を有してなり、最上段の身部２の開口端に蓋部４が印籠嵌合される紙製重箱１において、所定形状の原紙Ａがボックス状に折り曲げられて形成される内箱５Ａ・５Ｂ・５Ｃと、長尺状の原紙Ｂが上下端部をＶ字状の折曲溝２１・２３に沿って内側に折り畳められ、さらに左右端部２６・２６をＶ字状の折曲溝２５に沿って角環状に折り曲げられて形成される外枠体６Ａ・６Ｂと、で構成され、身部２・３は、上面開放した状態の内箱５Ａ・５Ｂの外周に外枠体６Ａが接着嵌合され、開口端にて内箱５Ａ・５Ｂの周壁１２の上端部が外枠体６Ａより上方に突出されるものであるため、耐久性を向上できるとともに、外観の品質及びデザイン性に優れた重箱とすることができる。 As described above, the paper jubako 1 of this embodiment has a plurality of body parts 2 and 3, and the lid part 4 is fitted into the open end of the uppermost body part 2. 1, inner boxes 5A, 5B, and 5C are formed by folding a predetermined shape of base paper A into a box shape, and a long base paper B has its upper and lower ends along V-shaped bending grooves 21 and 23. The outer frame bodies 6A and 6B are formed by folding the left and right ends 26 and 26 into a rectangular ring shape along the V-shaped bending groove 25. 3, the outer frame body 6A is adhesively fitted to the outer periphery of the inner boxes 5A and 5B with their tops open, and the upper end of the peripheral wall 12 of the inner boxes 5A and 5B protrudes upward from the outer frame body 6A at the open end. Therefore, the durability can be improved and the box can be made with excellent quality and design in appearance.

すなわち、本実施例の紙製重箱１は、身部２・３において、所定形状の原紙Ａがボックス状に折り曲げられて形成される内箱５Ａ・５Ｂに長尺状の原紙Ｂが角環状に折り曲げられて形成される外枠体６Ａが接着嵌合されて形成されるものであるため、外枠体６Ａに対する内箱５Ａ・５Ｂの取付強度が高く、底板１０の耐久性に優れるとともに、外枠体６Ａにて角が立った溝の無い外観の重箱を得ることができ、質感に優れた仕上がりとすることができる。また、外枠体６Ａに対する内箱５Ａ・５Ｂの取付位置の変更が容易であるため、例えば、底板１０と端板２２とを同一平面上に配置できる等、多様なデザインのバリエーションが可能となる。 That is, in the paper box 1 of this embodiment, in the body parts 2 and 3, a long base paper B is formed into a rectangular ring shape in inner boxes 5A and 5B, which are formed by folding base paper A of a predetermined shape into a box shape. Since the outer frame body 6A is formed by being bent and adhesively fitted, the attachment strength of the inner boxes 5A and 5B to the outer frame body 6A is high, the durability of the bottom plate 10 is excellent, and the outer frame body 6A is bonded and fitted. With the frame body 6A, a multi-layered box with an appearance without sharp corners and grooves can be obtained, and a finish with excellent texture can be obtained. Furthermore, since it is easy to change the mounting position of the inner boxes 5A and 5B relative to the outer frame 6A, various design variations are possible, for example, the bottom plate 10 and the end plate 22 can be placed on the same plane. .

特に、身部２は、内箱５Ａの底板１０が外枠体６Ａの端板２２より上方に位置されるため、複数の身部２を印籠嵌合にて重ねることができ、多段重箱として多様なデザインのバリエーションが可能となる。 In particular, since the bottom plate 10 of the inner box 5A is located above the end plate 22 of the outer frame 6A, a plurality of body parts 2 can be stacked together by inro fitting, and can be used as a multi-tiered box. Many design variations are possible.

また、身部３は、内箱５Ｂの底板１０が外枠体６Ａの端板２２と同一平面上に位置されるため、身部３を底箱として使用することで、全体として各面が平面状の直方体形状としたデザイン性により優れた重箱とすることができる。 In addition, since the bottom plate 10 of the inner box 5B and the end plate 22 of the outer frame body 6A are located on the same plane, each surface of the body 3 is flat as a whole by using the body 3 as a bottom box. Due to the design of the rectangular parallelepiped shape, it is possible to make an excellent multi-box.

また、蓋部４は、下面開放した状態の内箱５Ｃの外周に外枠体６Ｂが接着嵌合され、開口端にて外枠体６Ｂの下端部が内箱５Ｃより下方に突出されるとともに、内箱５Ｃの底板１０が外枠体６Ｂの端板２２と同一平面上に位置されるため、蓋部４において、外枠体６Ｂにて角が立った溝の無い外観の重箱を得ることができ、質感に優れた仕上がりとすることができるとともに、全体として各面が平面状の直方体形状としたデザイン性により優れた重箱とすることができる。 In addition, in the lid part 4, an outer frame body 6B is adhesively fitted to the outer periphery of the inner box 5C with its bottom surface open, and the lower end of the outer frame body 6B protrudes downward from the inner box 5C at the open end. Since the bottom plate 10 of the inner box 5C is located on the same plane as the end plate 22 of the outer frame 6B, it is possible to obtain a multi-layered box in the lid part 4 with an appearance without grooves with sharp corners in the outer frame 6B. It is possible to obtain a finish with excellent texture, and also to obtain a multi-box with excellent design due to the rectangular parallelepiped shape with each surface being flat as a whole.

また、内箱５Ａ・５Ｂ・５Ｃは、底板１０の各周辺より周壁１２が立設され、底板１０及び周壁１２の外面が上貼紙Ｃにて貼り包まれた貼箱が用いられるため、内箱５Ａ・５Ｂ・５Ｃの組み立てが容易であるとともに、剛性が高くより質感に優れた仕上がりとすることができる。 In addition, the inner boxes 5A, 5B, and 5C use a pasted box in which the peripheral wall 12 is erected from each periphery of the bottom plate 10, and the outer surfaces of the bottom plate 10 and the peripheral wall 12 are wrapped with the upper sticker C, so the inner box It is easy to assemble 5A, 5B, and 5C, and it is possible to achieve a finish with high rigidity and excellent texture.
