Description

本考案は、収容する商品を包装する上端開口の身箱と下端開口の蓋とから成る包装箱に関し、さらに詳しくは、収容する商品の上部が露出する身箱を用いる包装箱に関する。 The present invention relates to a packaging box comprising a body box having an upper end opening for packaging a product to be accommodated and a lid having a lower end opening, and more particularly to a packaging box using a body box in which the upper part of the product to be accommodated is exposed.

従来より、商品を収容して展示及び輸送する場合には、商品を収容する上端開口の身箱と、この身箱とは別体の下端開口の蓋とから成る包装箱が用いられている。この包装箱の中には、蓋をとって店頭で商品を展示する際、見栄えをよくしたり、商品を確認しやすくするため、収容する商品の上部が露出する身箱を用いる場合がある。つまり、この場合には、身箱の周壁の高さは、収容する商品の高さよりも低く形成されるようになっている。 2. Description of the Related Art Conventionally, when a product is stored and displayed and transported, a packaging box is used which includes a body box with an upper end opening for storing the product and a lid with a lower end opening separate from the body box. In some cases, a packaging box is used in which the upper part of the product to be stored is exposed in order to improve the appearance or make it easier to check the product when the product is displayed at the store with the lid removed. That is, in this case, the height of the peripheral wall of the body box is formed to be lower than the height of the product to be accommodated.

しかして、このような身箱を用いた包装箱は、商品を展示するときは重宝するが、商品を収容して保管したり、輸送したりするときは、その取り扱いが困難となる。即ちこのような身箱を用いた包装箱は、蓋をした状態では、蓋の荷重が直接商品にかかってしまい、さらに、この包装箱を何段にも重ねたり、輸送時に他の物が載せられたりすると、それらの荷重も直接的に商品にかかってしまい、その結果、商品を傷めてしまうという問題点がある。そこで、このような問題点を解消するため、蓋の内側に係止段部を設けて、商品に直接的に荷重がかからない技術が開示されている（特許文献１参照）。 Thus, a packaging box using such a body box is useful when displaying products, but is difficult to handle when storing and transporting products. In other words, in the case of a packaging box using such a body box, the load on the lid is directly applied to the product when the lid is covered. If they are applied, those loads are also directly applied to the product, and as a result, the product is damaged. Therefore, in order to solve such problems, a technique is disclosed in which a locking step is provided inside the lid so that no load is directly applied to the product (see Patent Document 1).

この特許文献１の技術について、図面を参照しながら説明する。図８は、組み立てれば図９に示す蓋Ｐ１０となるシート材Ｐ５１を示す展開図であり、図９は、蓋Ｐ１０の裏側を斜め上方から見た斜視図である。段ボール等から成るシート材Ｐ５１は、天壁Ｐ１１と、該天壁Ｐ１１の各外周縁に、夫々側壁Ｐ１２Ａ、Ｐ１２Ｂ、Ｐ１２Ｃ、Ｐ１２Ｄを連設して形成されている。また、Ｐ１２Ａ、Ｐ１２Ｃには、隣接する側壁Ｐ１２Ｂ、Ｐ１２Ｄに貼着するための糊代Ｐ１４が設けられている。また、隣接する側壁Ｐ１２Ａ〜Ｐ１２Ｄの稜部には、図示しない身箱の周壁の上端に係止するための係止段部Ｐ１６が設けられている。 The technique of Patent Document 1 will be described with reference to the drawings. FIG. 8 is a development view showing the sheet material P51 that becomes the lid P10 shown in FIG. 9 when assembled, and FIG. 9 is a perspective view of the back side of the lid P10 as viewed obliquely from above. A sheet material P51 made of cardboard or the like is formed by connecting a side wall P12A, P12B, P12C, and P12D to the top wall P11 and the outer peripheral edges of the top wall P11. In addition, an adhesive margin P14 for adhering to the adjacent side walls P12B and P12D is provided on P12A and P12C. Moreover, the latching step part P16 for latching to the upper end of the surrounding wall of the body box which is not shown in figure is provided in the ridge part of adjacent side wall P12A-P12D.

このように形成されたシート材Ｐ５１を図８に破線で示した折曲線によって折り曲げ組み立てると、図９に示す蓋Ｐ１０となる。この際、係止段部Ｐ１６も、折曲線によって折り込まれ、隣接する側壁Ｐ１２Ａ〜Ｐ１２Ｄの稜部の上端の隅を頂点とした略三角板状に、内向きに突出した状態で形成されることになる。 When the sheet material P51 formed in this way is folded and assembled along a folding line shown by a broken line in FIG. 8, a lid P10 shown in FIG. 9 is obtained. At this time, the latching step portion P16 is also folded by a folding line, and is formed in a substantially triangular plate shape with the top corner of the ridge portion of the adjacent side walls P12A to P12D protruding inward. Become.

そして、このように構成された蓋Ｐ１０を上部が露出するように商品を収容した身箱に外嵌すると、係止段部Ｐ１６の下部が身箱の周壁の上端に係止し、その結果、蓋Ｐ１０の天壁Ｐ１１は、身箱の周壁の上端から係止段部Ｐ１６の高さ分だけ上方に浮いた状態で保持される。これにより、商品に直接的に荷重がかることを防止でき、商品を傷めることはない。 Then, when the lid P10 thus configured is externally fitted to the body box containing the product so that the upper part is exposed, the lower part of the locking step part P16 is locked to the upper end of the peripheral wall of the body box, The top wall P11 of the lid P10 is held in a state of floating upward from the upper end of the peripheral wall of the body box by the height of the locking step portion P16. Thereby, it can prevent that a load is directly applied to goods, and does not damage goods.

ところで、上記した特許文献１の技術では、蓋Ｐ１０を組み立てる際、糊代Ｐ１４を側壁Ｐ１２Ｂ、Ｐ１２Ｄにホットメルトなどの接着剤にて貼着する構成となっている。しかしながら、この特許文献１のように、蓋を接着剤を使用して組み立てる構成にすると、糊代と側壁とを接着するための専用機が必要になる。周知のように、段ボール等は、打抜装置によってどのような複雑な形状でも一工程で連続した一枚のブランクとして打ち抜かれ、所定の形状に組み立てることができるので、よって、このように専用機が必要になると、専用機の分だけ生産コストがアップしてしまうという問題点がある。 By the way, in the technique of above-mentioned patent document 1, when assembling the lid | cover P10, it has the structure which adheres the glue margin P14 to the side walls P12B and P12D with adhesives, such as a hot melt. However, when the lid is assembled using an adhesive as in Patent Document 1, a dedicated machine for bonding the adhesive margin and the side wall is required. As is well known, corrugated cardboard or the like can be punched out as a single continuous blank in one process in any complicated shape by a punching device and assembled into a predetermined shape. However, there is a problem that the production cost will increase by the amount of dedicated machines.

また、接着剤を使用して組み立てる工程では、一般的に機械組で大量生産には向くが、小ロットの生産には不向きで対応が困難という問題点がある。
さらに、露出する高さが異なる商品を収容する場合には、係止段部Ｐ１６を、図８に示す矢印ＰＡ、ＰＢの２方向に、その長さを調整する必要があり、即ち身箱から露出する高さの異なる様々な商品を収容するには、煩わしい作業が必要になり容易に対応できないという問題点もある。 Also, the process of assembling using an adhesive is generally suitable for mass production with a mechanical assembly, but has a problem that it is not suitable for production of a small lot and is difficult to cope with.
Furthermore, when accommodating products with different exposed heights, it is necessary to adjust the length of the locking step portion P16 in the two directions of arrows PA and PB shown in FIG. In order to accommodate various products with different heights to be exposed, there is a problem that a troublesome work is required and it cannot be easily handled.

本考案は、上記した問題点に鑑みなされたもので、その目的とするところは、小ロットの生産にも対応でき、収容する商品の上部が露出する身箱を用いた場合であっても、蓋に接着剤を使用することなく収容する商品に荷重がかかることを防止できる手段を有した、美粧性に優れ、且つ露出する高さが異なる商品であっても容易に対処して収容することのできる包装箱を提供することにある。 The present invention has been made in view of the above-mentioned problems, and its purpose is to support the production of small lots, even when using a body box where the upper part of the product to be stored is exposed, It has a means that can prevent the load from being applied to the product to be stored without using an adhesive on the lid, and it is easy to deal with and store even products with excellent cosmetics and different exposed heights. It is to provide a packaging box that can be used.

このような問題を解決するために、本考案の包装箱は、請求項１に記載したように、底壁、該底壁の周囲に連設される周壁（周壁３０）を備えた上端開口の身箱（身箱５０）と、該身箱に外嵌する、一枚の平面状に形成されたシート材（シート材５１）を折り曲げることにより、天壁（天壁１１）、該天壁の周囲に連設されて周壁（周壁１２）を形成する、互いに対向する一対の第一側壁（側壁１２Ａ、１２Ｃ）及び前記第一側壁に対して直交した状態で互いに対向する一対の第二側壁（側壁１２Ｂ、１２Ｄ）、を備えた下端開口の蓋（蓋１０）とから成る直方体状の包装箱（包装箱１）であって、前記蓋は、前記第一側壁の４辺の内の互いに平行で前記天壁に連設されない２辺（折曲線２１）に夫々連設され、前記第二側壁の内側と重合する一対の接続片（折込片１４）と、前記第二側壁の４辺の内の前記天壁とは反対側の１辺（折曲線２２）に連設され、前記第二側壁の内側と重合する係止段部（係止段部１６）が設けられた折返壁（折返壁３Ｂ、３Ｄ）と、を備え、前記蓋を組み立てる際、前記折返壁を折り曲げて前記第二側壁に重合して、前記接続片を該折返壁と該第二側壁とで挟着すると共に、前記係止段部が、前記天壁の下方で内向きに突出し、これにより前記蓋を前記身箱に外嵌したとき、前記係止段部が該身箱の前記周壁の上端（上端３０Ａ）に係止することを要旨とする。 In order to solve such a problem, the packaging box according to the present invention includes a bottom wall and a top wall provided with a peripheral wall (peripheral wall 30) continuously provided around the bottom wall. By folding a body box (body box 50) and a sheet material (sheet material 51) formed in a flat shape and fitted on the body box, the top wall (top wall 11), A pair of first side walls (side walls 12A and 12C) facing each other and forming a peripheral wall (peripheral wall 12) connected to the periphery, and a pair of second side walls facing each other in a state orthogonal to the first side wall ( A rectangular parallelepiped packaging box (packaging box 1) having a lid (lid 10) with a lower end opening provided with side walls 12B, 12D), the lids being parallel to each other among the four sides of the first side wall. In each of the two sides (folded curve 21) that are not connected to the top wall, they overlap with the inside of the second side wall. A pair of connecting pieces (folding piece 14) and one side (folding curve 22) on the opposite side to the top wall among the four sides of the second side wall are connected to the inside of the second side wall. A folding wall (folding wall 3B, 3D) provided with a locking step (locking step 16), and when assembling the lid, the folding wall is folded and superposed on the second side wall, When the connecting piece is sandwiched between the folded wall and the second side wall, and the locking step protrudes inward below the top wall, and thereby the lid is fitted on the body box. The gist is that the locking step is locked to the upper end (upper end 30A) of the peripheral wall of the body box.

つまり、請求項１に記載の包装箱は、一枚の平面状に形成されたシート材を折り曲げて組み立てられる下端開口の蓋と、上端開口の身箱とで直方体状に構成され、蓋は、天壁と、天壁の周囲に連設されて蓋の周壁を形成する互いに対向する一対の第一側壁及び第二側壁とを備えている。 That is, the packaging box according to claim 1 is configured in a rectangular parallelepiped shape by a lower end opening lid that is assembled by folding a single sheet of sheet material and an upper end opening body box, A top wall and a pair of first and second side walls facing each other, which are continuously provided around the top wall and form a peripheral wall of the lid, are provided.

そして、第一側壁は、第二側壁の内側と重合する一対の接続片を、第二側壁は、この第二側壁の内側と重合する折返壁を備えており、折返壁を折り曲げて第二側壁の内側に重合して蓋を組み立てたとき、この折り曲げた折返壁と第二側壁とで接続片を挟み込んで挟着する。さらに、折返壁は係止段部を備えており、折返壁を折り曲げて蓋を組み立てたとき、この係止段部が天壁の下方で内向きに突出し、これにより、蓋を身箱に外嵌したとき、係止段部が身箱の周壁の上端に係止する。 The first side wall includes a pair of connection pieces that overlap with the inner side of the second side wall, and the second side wall includes a folded wall that overlaps with the inner side of the second side wall. When the lid is assembled by superimposing on the inside, the connection piece is sandwiched between the folded wall and the second side wall. Further, the folding wall has a locking step, and when the lid is assembled by folding the folding wall, the locking step protrudes inward below the top wall, so that the lid is removed from the body box. When fitted, the locking step is locked to the upper end of the peripheral wall of the body box.

従って、このように構成される本考案の包装箱においては、収容する商品の上部（Ｔ４）が露出する身箱に対して、商品に直接的に荷重がかることを防止できる係止段部を備えた蓋を組み立てるとき、接着剤を使用することなく、接続片を固定して係止段部を形成することができるので、接着するための専用機が必要なく、その結果、生産コストを抑えることができる。また、接着剤を使用しないので、小ロットの生産にも手組（機械組に対して手折り製函）で容易に対応することも可能となり、さらに、組み立てた蓋を容易に元の一枚のシート材に戻すこともできる。 Accordingly, the packaging box of the present invention configured as described above includes a locking step portion that can prevent the product from being directly loaded with respect to the body box from which the upper part (T4) of the product to be stored is exposed. When assembling the lid, it is possible to fix the connecting piece and form a locking step without using an adhesive, so there is no need for a dedicated machine for bonding, resulting in reduced production costs Can do. In addition, since no adhesive is used, it is possible to easily handle small-lot production by hand assembly (hand-folding with respect to the machine assembly). It can also be returned to the sheet material.

ここで、折返壁の具体的な構成は、次のようにするとよい。即ち請求項２に記載の包装箱は、請求項１に記載の包装箱において、前記折返壁は、前記第二側壁とほぼ同一形状に形成されると共に、該折返壁の４辺の内の前記第二側壁とは反対側の１辺（折曲線２３）に連設される折込片（折込片５Ｂ、５Ｄ）を備え、該折込片は、前記折返壁を折り曲げて前記第二側壁に重合したとき、前記天壁と重合することを要旨とする。 Here, the specific configuration of the folding wall may be as follows. That is, the packaging box according to claim 2 is the packaging box according to claim 1, wherein the folded wall is formed in substantially the same shape as the second side wall, and the four of the folded walls have the four sides. A folding piece (folding pieces 5B, 5D) provided on one side (folding curve 23) opposite to the second side wall is provided, and the folding piece is folded on the folded wall and overlapped with the second side wall. In some cases, polymerization is performed with the top wall.

従って、このように構成される本考案の包装箱においては、折返壁が第二側壁とぴったりと重合し、且つ折込片が天壁と重合するので、これら折返壁の形状及び折込片が折り曲げられている折返壁のストッパーとして機能し、折返壁が元に戻ろうとする方向への移動を規制するので、その結果、接着剤を使用しなくても、強固に接続片を折返壁と第二側壁とで挟着して固定することができる。 Therefore, in the packaging box of the present invention configured as described above, the folded wall is overlapped with the second side wall and the folded piece is overlapped with the top wall, so that the shape of the folded wall and the folded piece are folded. It functions as a stopper for the folded wall and regulates the movement of the folded wall in the direction to return to the original, so that the connection piece is firmly connected to the folded wall and the second side wall without using an adhesive. And can be clamped and fixed.

また、折込片の具体的な構成は、次のようにするとよい。即ち請求項３に記載の包装箱は、請求項２に記載の包装箱において、前記折込片は、前記折返壁と連設される辺が、該折返壁の該折込片と連設される辺とほぼ同じ長さの矩形状に形成され、前記係止段部は、該折込片の４辺の内の互いに平行で前記折返壁に連設されない２辺に夫々連設され、前記折込片を折り曲げて前記天壁と重合したとき、前記第一側壁又は／及び前記折返壁と当接することを要旨とする。 The specific configuration of the folded piece is preferably as follows. That is, the packaging box according to claim 3 is the packaging box according to claim 2, wherein the side of the folded piece that is connected to the folded wall is a side that is connected to the folded piece of the folded wall. Are formed in a rectangular shape having substantially the same length as each other, and the engaging stepped portions are connected to two sides that are parallel to each other among the four sides of the folded piece and are not continuous to the folded wall. The gist is to contact the first side wall and / or the folded wall when folded and overlapped with the top wall.

従って、このように構成される本考案の包装箱においては、折込片が一対の第一側壁の間にぴったりと嵌り込むようにして天壁と重合し、且つ折込片に連設された係止段部が第一側壁又は／及び折返壁と当接するので、上記した請求項２の折返壁の形状に加え、これら折込片及び係止段部が折り曲げられている折返壁のストッパーとして機能し、折返壁が元に戻ろうとする方向への移動を規制するので、その結果、接着剤を使用しなくても、より強固に接続片を折返壁と第二側壁とで挟着して固定することができる。さらに、このように係止段部を折込片に連設する構成としたことで、係止段部を容易に天壁の下方で内向きに突出させて形成することができる。 Therefore, in the packaging box of the present invention configured as described above, the folding step overlaps with the top wall so that the folding piece fits exactly between the pair of first side walls, and is a locking step portion provided continuously with the folding piece. , Abuts against the first side wall and / or the folded wall, so that in addition to the shape of the folded wall according to claim 2, the folded piece and the locking step portion function as a folded wall stopper, and the folded wall Restricts the movement in the direction of returning to the original direction. As a result, the connection piece can be more firmly clamped and fixed between the folded wall and the second side wall without using an adhesive. . Furthermore, since the latching step portion is connected to the folded piece in this manner, the latching step portion can be easily formed inwardly projecting below the top wall.

また、係止段部の具体的な構成は、次のようにするとよい。即ち請求項４に記載の包装箱は、請求項３に記載の包装箱において、前記係止段部は、前記折込片に連設される第一係止片（第一係止片１６ａ、１６ｃ）と、該第一係止片に連設され、前記折込片に連設されない第二係止片（第二係止片１６ｂ、１６ｄ）と、を備え、前記折込片を折り曲げて前記天壁と重合したとき、前記第一係止片は前記第一側壁と重合し、前記第二係止片は、該第一係止片との連設箇所（折曲線２５）から前記折込片の下方で内向きに突出して前記折返壁と当接することを要旨とする。 Further, the specific configuration of the locking step portion may be as follows. That is, the packaging box according to claim 4 is the packaging box according to claim 3, wherein the locking step portion is a first locking piece (first locking pieces 16a, 16c) connected to the folding piece. ) And a second locking piece (second locking pieces 16b, 16d) that is connected to the first locking piece and is not connected to the folding piece, and the top wall is bent by folding the folding piece. When the first locking piece overlaps with the first side wall, the second locking piece is located below the folding piece from the connection point (folding line 25) with the first locking piece. The gist is to project inwardly and come into contact with the folded wall.

従って、このように構成される本考案の包装箱においては、係止段部を第一係止片と第二係止片とに分けて形成し、折込片に連設される第一係止片を第一側壁と重合し、且つ第一係止片のみに連設される第二係止片を折込片の下方で内向きに突出して折返壁と当接するので、蓋の周壁等に穴を開けて係止段部を定位置に固定するためのロックする必要がなく、その結果、美粧性に優れた包装箱を形成することができる。さらに、このような係止段部の構成により、折返壁のストッパー機能を強化し、より強固に接続片を折返壁と第二側壁とで挟着して固定することができると共に、係止段部をより簡単な構成で実現することができる。 Therefore, in the packaging box of the present invention configured as described above, the locking step portion is divided into the first locking piece and the second locking piece, and the first locking is provided continuously with the folding piece. Since the piece is overlapped with the first side wall and the second locking piece connected to only the first locking piece protrudes inward below the folding piece and comes into contact with the folding wall, a hole is formed in the peripheral wall of the lid. There is no need to lock the fixing step portion in place, and as a result, a packaging box with excellent cosmetics can be formed. Further, the structure of the locking step portion as described above can strengthen the stopper function of the folding wall and more firmly fix the connection piece by sandwiching it between the folding wall and the second side wall. The part can be realized with a simpler configuration.

ここで、係止段部のより具体的な構成として、第一係止片及び第二係止片の構成は次のようにするとよい。即ち請求項５に記載の包装箱は、請求項４に記載の包装箱において、前記第一係止片及び前記第二係止片は、夫々ほぼ同一の略矩形状に形成され、前記第一係止片の前記折込片と連設される辺（折曲線２４）は、該折込片の該第一係止片と連設される辺より前記折返壁側から所定区間だけ短く形成され、前記第二係止片は、該第一係止片の４辺の内の互いに平行で前記折込片に連設されない２辺の内、前記折返壁側に位置する１辺（折曲線２５）に連設されることを要旨とする。 Here, as a more specific configuration of the locking step portion, the configuration of the first locking piece and the second locking piece may be as follows. That is, the packaging box according to claim 5 is the packaging box according to claim 4, wherein the first locking piece and the second locking piece are formed in substantially the same substantially rectangular shape. The side (folding curve 24) provided continuously with the folding piece of the locking piece is formed shorter than the side provided with the first locking piece of the folding piece by a predetermined interval from the folding wall side, The second locking piece is connected to one side (folding curve 25) located on the folding wall side, out of two sides that are parallel to each other among the four sides of the first locking piece and are not connected to the folding piece. The main point is that it is established.

従って、このように構成される本考案の包装箱においては、身箱に収容する商品の露出する高さが異なる場合であっても、係止段部の高さ（Ｔ３）を変更するだけ（一方向だけの変更）で極めて容易に対処することができ、その結果、身箱から露出する高さの異なる様々な商品を容易に収容することが可能となる。また、第一係止片を第一側壁と重合し、且つ第二係止片を折込片の下方で内向きに突出して折返壁と当接する構成を、より簡単な構成で実現することができる。さらに、このような第一係止片及び第二係止片の構成により、折返壁のストッパー機能を強化し、さらに強固に接続片を折返壁と第二側壁とで挟着して固定することができる。 Therefore, in the packaging box of the present invention configured as described above, the height (T3) of the locking step portion is only changed even when the exposed heights of the products accommodated in the body box are different ( It is possible to deal with it very easily with a change in only one direction, and as a result, it is possible to easily accommodate various products exposed at different heights from the body box. In addition, a configuration in which the first locking piece is overlapped with the first side wall, and the second locking piece projects inward below the folding piece and comes into contact with the folded wall can be realized with a simpler configuration. . Furthermore, with the configuration of the first locking piece and the second locking piece, the stopper function of the folding wall is strengthened, and the connection piece is firmly clamped and fixed between the folding wall and the second side wall. Can do.

以下に、本考案の包装箱１に係る実施形態を図面に基づき説明する。まず、図３を参照しながら、本考案の包装箱１の概要について説明する。図３は、矢印Ａで示すように、蓋１０を身箱５０から取り外した状態を示す包装箱１の斜視図である。なお、図３において、蓋１０は、その裏側を斜め上方から見た斜視図で示され、身箱５０は、商品８０を収容した状態で、その表側を斜め上方から見た斜視図で示されている。 1. Outline of Packaging Box 1 Hereinafter, an embodiment according to the packaging box 1 of the present invention will be described with reference to the drawings. First, the outline | summary of the packaging box 1 of this invention is demonstrated, referring FIG. FIG. 3 is a perspective view of the packaging box 1 showing a state where the lid 10 is removed from the body box 50 as indicated by an arrow A. FIG. In FIG. 3, the lid 10 is shown in a perspective view of the back side as seen from obliquely above, and the body box 50 is shown in a perspective view of the front side as seen from obliquely above in a state where the product 80 is accommodated. ing.

包装箱１は、図３に示すように、商品（ハッチング箇所）８０を収容する上端開口の身箱５０と、この身箱５０とは別体の下端開口の蓋１０とから構成されている。身箱５０は、図示するように、収容する商品８０の上部が周壁３０から露出するように形成されている。一方、蓋１０は、その裏側の周壁１２の各稜部上端に係止段部１６を４つ備えており、周壁１２の高さは、身箱５０の周壁３０よりも該係止段部１６のほぼ高さ分だけ長く形成されている。 As shown in FIG. 3, the packaging box 1 includes a body box 50 having an upper end opening that accommodates a product (hatched portion) 80 and a lid 10 having a lower end opening that is separate from the body box 50. The body box 50 is formed so that the upper part of the product 80 to be accommodated is exposed from the peripheral wall 30 as illustrated. On the other hand, the lid 10 includes four locking step portions 16 at the upper ends of the respective ridges of the peripheral wall 12 on the back side, and the height of the peripheral wall 12 is higher than that of the peripheral wall 30 of the body box 50. It is formed longer by almost the height of.

このように構成される蓋１０を、上部が露出するように商品８０を収容した身箱５０に外嵌すると、係止段部１６の下端が身箱５０の周壁３０の上端３０Ａに係止し、蓋１０の天壁１１は、身箱５０の上端３０Ａから係止段部１６のほぼ高さ分だけ上方に浮いた状態で保持される。係止段部１６の高さは、商品８０の露出部分の高さより予め長く形成されるので、商品８０の上端と蓋１０の天壁１１とは、所定の隙間が形成されて接触することはない。これにより、包装箱１は、商品８０の上部が露出する身箱５０を使用していても、この包装箱１を何段にも重ねたり、輸送時に他の物が載せられたりしても、商品８０に直接的に荷重がかることを防止でき、商品を傷めることはない。 When the lid 10 thus configured is externally fitted to the body box 50 containing the product 80 so that the upper part is exposed, the lower end of the locking step 16 is locked to the upper end 30A of the peripheral wall 30 of the body box 50. The top wall 11 of the lid 10 is held in a state of floating upward from the upper end 30 A of the body box 50 by substantially the height of the locking step 16. Since the height of the locking step 16 is formed in advance longer than the height of the exposed portion of the product 80, the upper end of the product 80 and the top wall 11 of the lid 10 are in contact with each other with a predetermined gap formed. Absent. Thereby, even if the packaging box 1 uses the body box 50 in which the upper part of the product 80 is exposed, even if this packaging box 1 is stacked in many layers, or other items are placed during transportation, The product 80 can be prevented from being directly loaded, and the product is not damaged.

３．蓋１０の組み立て
次に、図１〜図７を参照しながら蓋１０の組み立てについて説明する。なお、図２は、組み立てられた蓋１０の裏側を斜め上方から見た斜視図であり、図４は、（Ａ）は組み立てられた蓋１０の背面図、（Ｂ）は商品８０を収容した身箱５０の平面図であり、図５は、図４における蓋１０を商品８０を収容した身箱５０に外嵌した包装箱１のＡ−Ａ断面図であり、図６は、折返壁３Ｂ、折込片５Ｂ、係止段部１６（第一係止片１６ａ、第二係止片１６ｂ）の折り曲げ方向を説明するための説明図、図７は、折返壁３Ｂ、折込片５Ｂ、係止段部１６（第一係止片１６ａ、第二係止片１６ｂ）が折り曲げられた状態を示す組み立て途中の蓋１０の裏側を斜め上方から見た斜視図である。 3. Next, the assembly of the lid 10 will be described with reference to FIGS. 2 is a perspective view of the rear side of the assembled lid 10 as viewed obliquely from above. FIG. 4A is a rear view of the assembled lid 10 and FIG. 5 is a plan view of the body box 50. FIG. 5 is a cross-sectional view taken along the line AA of the packaging box 1 in which the lid 10 in FIG. 4 is externally fitted to the body box 50 containing the product 80. FIG. FIG. 7 is an explanatory diagram for explaining the folding direction of the folding piece 5B and the locking step 16 (first locking piece 16a, second locking piece 16b). FIG. 7 shows the folding wall 3B, the folding piece 5B, It is the perspective view which looked at the back side of the lid | cover 10 in the middle of the assembly which shows the state by which the step part 16 (1st locking piece 16a, 2nd locking piece 16b) was bent from diagonally upward.

蓋１０を組み立てるには、シート材５１を図１に示した折曲線１７〜２５に沿って折り曲げていく。まず、側壁１２Ａ、１２Ｂ、１２Ｃ、１２Ｄを折曲線１７〜２０に沿って谷折りにし、次に折込片１４夫々を折曲線２１に沿って谷折りにする。 In order to assemble the lid 10, the sheet material 51 is bent along the folding lines 17 to 25 shown in FIG. First, the side walls 12 A, 12 B, 12 C, 12 D are valley-folded along the folding lines 17 to 20, and then each of the folding pieces 14 is valley-folded along the folding line 21.

次に、折返壁３Ｂ、３Ｄ、折込片５Ｂ、５Ｄ、係止段部１６（第一係止片１６ａ、１６ｃ、第二係止片１６ｂ、１６ｄ）を折曲線２２〜２５に沿って折り曲げる。なお、折返壁３Ｂ、折込片５Ｂ、第一係止片１６ａ、第二係止片１６ｂを折り曲げる構成は、折返壁３３Ｄ、折込片５Ｄ、第一係止片１６ｃ、第二係止片１６ｄを折り曲げる構成と同一であるので、以下は、前者の構成についてのみ説明する。図６を参照して、本図では、折返壁３３Ｄ、折込片５Ｄ、第一係止片１６ｃ、第二係止片１６ｄが折り曲げられて蓋１０に既に折り込まれた状態を示しており、一方、折返壁３Ｂ、折込片５Ｂ、第一係止片１６ａ、第二係止片１６ｂは未だ折り曲げられておらず、折返壁３Ｂは側壁１２Ｂから上方に延びて、折込片５Ｂ、第一係止片１６ａ、第二係止片１６ｂと共に、該側壁１２Ｂと共にに天壁１１に対して垂直状に立設（直交）した状態となっている。 Next, the folding walls 3B and 3D, the folding pieces 5B and 5D, and the locking step portions 16 (first locking pieces 16a and 16c and second locking pieces 16b and 16d) are bent along the folding lines 22 to 25. The folding wall 3B, the folding piece 5B, the first locking piece 16a, and the second locking piece 16b are bent so that the folding wall 33D, the folding piece 5D, the first locking piece 16c, and the second locking piece 16d are folded. Since the configuration is the same as that for bending, only the former configuration will be described below. Referring to FIG. 6, this figure shows a state in which the folded wall 33D, the folded piece 5D, the first locking piece 16c, and the second locking piece 16d are folded and already folded into the lid 10. The folding wall 3B, the folding piece 5B, the first locking piece 16a, and the second locking piece 16b are not yet bent, and the folding wall 3B extends upward from the side wall 12B, and the folding piece 5B, the first locking piece Together with the piece 16a and the second locking piece 16b, it is in a state of being erected (orthogonal) perpendicular to the top wall 11 together with the side wall 12B.

この状態から、まず折曲線２５に沿って第一係止片１６ａ下辺に連設している第二係止片１６ｂを、夫々矢印Ｄ及び矢印Ｅ方向に折り曲げる（図１において山折り）。次に、折曲線２４に沿って折込片５Ｂの左右両辺に連設している第一係止片１６ａを、夫々矢印Ｆ及び矢印Ｇ方向に折り曲げる（図１において山折り）。この場合には、第二係止片１６ｂも、第一係止片１６ａに連動して一緒に矢印Ｆ及び矢印Ｇ方向に折り曲がる。次に、折曲線２３に沿って折返壁３Ｂの上辺に連設している折込片５Ｂを、矢印Ｃ方向に折り曲げる（図１において山折り）。そして最後に、側壁１２Ｂの上辺に連設している折返壁３Ｂを、矢印Ｂ方向に折り曲げる（図１において谷折り）。図７は、折返壁３Ｂを矢印Ｂ方向に折り曲げたときの一状態を示しており、この図７に示す状態からさらに折返壁３Ｂを折り曲げていくと、図２に示すように、折返壁３Ｂ、折込片５Ｂ、第一係止片１６ａ、第二係止片１６ｂは蓋１０に折り込まれた状態となり、これにより蓋１０が組み立てられる。 From this state, first, the second locking piece 16b connected to the lower side of the first locking piece 16a along the folding line 25 is bent in the directions of arrow D and arrow E, respectively (mountain fold in FIG. 1). Next, the first locking pieces 16a connected to the left and right sides of the folding piece 5B along the folding line 24 are bent in the directions of arrows F and G, respectively (mountain folding in FIG. 1). In this case, the second locking piece 16b is also bent in the directions of the arrows F and G together with the first locking piece 16a. Next, the folding piece 5B connected to the upper side of the folding wall 3B along the folding line 23 is bent in the direction of arrow C (mountain folding in FIG. 1). Finally, the folded wall 3B provided continuously with the upper side of the side wall 12B is bent in the direction of arrow B (valley fold in FIG. 1). FIG. 7 shows one state when the folded wall 3B is folded in the direction of arrow B. When the folded wall 3B is further folded from the state shown in FIG. 7, as shown in FIG. The folded piece 5B, the first locking piece 16a, and the second locking piece 16b are folded into the lid 10, whereby the lid 10 is assembled.

ここで、折返壁３Ｂを矢印Ｂ方向に折り曲げる際、側壁１２Ａ、１２Ｃの端部に設けられた折込片１４は、図６に示すように、側壁１２Ｂと重合した状態となっており、従って、折返壁３Ｂを折り曲げると、折込片１４は側壁１２Ｂと折返壁３Ｂとの間に挟まれ、固定される。この場合、折込片１４は、折返壁３Ｂが側壁１２Ｂと同一形状に形成されているので、折返壁３Ｂの左右両端が側壁１２Ａ、１２Ｃに当接して、しっかりと挟着される。さらに、折込片５Ｂが側壁１２Ｂ（天壁１１）の横寸と同一の矩形に形成され、且つ折込片５Ｂの両端に係止段部１６が形成されているので、図２に示すように、折込片５Ｂが天壁１１に重合し、且つ第一係止片１６ａが側壁１２Ａ、１２Ｃに重合し、第二係止片１６ｂが折返壁３Ｂ及び折込片５Ｂに当接するので、これら折込片５Ｂ、係止段部１６（第一係止片１６ａ、第二係止片１６ｂ）がストッパーとして機能して折返壁３Ｂの移動を規制し、その結果、折返壁３Ｂは強固に固定され、これにより折込片１４は、より強固に折返壁３Ｂと側壁１２Ｂとで挟着される。 Here, when the folded wall 3B is bent in the direction of arrow B, the folded pieces 14 provided at the end portions of the side walls 12A and 12C are in a state of being overlapped with the side wall 12B as shown in FIG. When the folding wall 3B is bent, the folding piece 14 is sandwiched and fixed between the side wall 12B and the folding wall 3B. In this case, since the folded wall 3B is formed in the same shape as the side wall 12B, the left and right ends of the folded wall 3B are in contact with the side walls 12A and 12C and are firmly clamped. Furthermore, since the folding piece 5B is formed in the same rectangle as the horizontal dimension of the side wall 12B (top wall 11), and the locking step 16 is formed at both ends of the folding piece 5B, as shown in FIG. Since the folding piece 5B is superimposed on the top wall 11, the first locking piece 16a is superimposed on the side walls 12A and 12C, and the second locking piece 16b is in contact with the folding wall 3B and the folding piece 5B, these folding pieces 5B The locking step 16 (the first locking piece 16a and the second locking piece 16b) functions as a stopper to restrict the movement of the folding wall 3B. As a result, the folding wall 3B is firmly fixed. The folded piece 14 is more firmly sandwiched between the folded wall 3B and the side wall 12B.

４．係止段部１６の構成
上述したように、蓋１０が組み立てられると、隣接する側壁１２Ａ〜１２Ｄの稜部４箇所の上端には、身箱５０の周壁３０の上端３０Ａに係止する係止段部１６が折り込まれて形成されることになる。この場合、係止段部１６（第一係止片１６ａ、第二係止片１６ｂ）は、図５に示すように、その下辺が天壁１１（折込片５Ｂ）よりほぼＴ３（図１も併せ参照）の長さだけ下側に位置することになる。このＴ３の長さ、即ち係止段部１６の高さは、予め商品８０の露出部分の高さＴ４よりもやや長く形成される。つまり、係止段部１６の高さＴ３は、身箱５０に収容する商品８０の露出部分の高さＴ４に対応して形成されることになる。 4). Configuration of Locking Step 16 As described above, when the lid 10 is assembled, the upper ends of the four ridges of the adjacent side walls 12A to 12D are locked to the upper end 30A of the peripheral wall 30 of the body box 50. The step portion 16 is formed by being folded. In this case, as shown in FIG. 5, the locking step 16 (first locking piece 16a, second locking piece 16b) has a lower side that is substantially T3 from the top wall 11 (folded piece 5B) (also in FIG. 1). It is located on the lower side by the length of (see also). The length of T3, that is, the height of the locking step portion 16 is formed in advance slightly longer than the height T4 of the exposed portion of the product 80. That is, the height T3 of the locking step 16 is formed corresponding to the height T4 of the exposed portion of the product 80 accommodated in the body box 50.

また、図４（Ａ）に示すように、第一係止片１６ａは、隣接する側壁１２Ａ、１２Ｂ又は側壁１２Ｂ、１２Ｃの稜部から所定区間の長さだけ離れた位置に配置され、第二係止片１６ｂは、第一係止片１６ａの端部から延びて斜め内向きに突出した状態で、その端部が折返壁３Ｂと当接している。つまり、第二係止片１６ｂは、折返壁３Ｂと第一係止片１６ａとの間に斜め状に配置されている。 Further, as shown in FIG. 4A, the first locking piece 16a is disposed at a position away from the ridges of the adjacent side walls 12A, 12B or the side walls 12B, 12C by the length of a predetermined section. The locking piece 16b extends from the end portion of the first locking piece 16a and protrudes obliquely inward, and the end portion is in contact with the folded wall 3B. That is, the second locking piece 16b is disposed obliquely between the folded wall 3B and the first locking piece 16a.

このように構成された係止段部１６を有する蓋１０を身箱５０に外嵌すると、図５に示すように、係止段部１６の下端が身箱５０の周壁３０の上端３０Ａに係止する。さらに、蓋１０の天壁１１（折込片５Ｂ）は、身箱５０の上端３０ＡからほぼＴ３の高さ分だけ上方に保持され、一方商品８０の露出部分の高さ、換言すれば身箱５０の上端３０Ａから上方に突出している高さＴ４は、このＴ３よりも短いので、商品８０と蓋１０の天壁１１（折込片５Ｂ）とは、所定の隙間（Ｔ３−Ｔ４）が形成されて接触することはない。これにより、包装箱１は、商品８０の上部が露出する身箱５０を使用していても、この包装箱１を何段にも重ねたり、輸送時に他の物が載せられたりしても、商品８０に直接的に荷重がかることを防止でき、商品を傷めることはない。 When the lid 10 having the locking step portion 16 configured as described above is externally fitted to the body box 50, the lower end of the locking step portion 16 is engaged with the upper end 30A of the peripheral wall 30 of the body box 50 as shown in FIG. Stop. Furthermore, the top wall 11 (folding piece 5B) of the lid 10 is held upward by the height of about T3 from the upper end 30A of the body box 50, while the height of the exposed portion of the product 80, in other words, the body box 50. Since the height T4 projecting upward from the upper end 30A is shorter than T3, a predetermined gap (T3-T4) is formed between the product 80 and the top wall 11 (folded piece 5B) of the lid 10. There is no contact. Thereby, even if the packaging box 1 uses the body box 50 in which the upper part of the product 80 is exposed, even if this packaging box 1 is stacked in many layers, or other items are placed during transportation, The product 80 can be prevented from being directly loaded, and the product is not damaged.

（１）商品８０の上部が露出す身箱５０の蓋１０を組み立てる際、ホットメルトなどの接着剤を使用することなく、折込片１４を固定して係止段部１６を形成することができるので、接着するための専用機が必要なく、その結果、生産コストを抑えることができる。また、接着剤を使用しないので、小ロットの生産にも手組（機械組に対して手折り製函）で容易に対応することも可能となり、さらに、組み立てた蓋１０を容易に元の一枚のシート材５１に戻すこともできる。 5. Effects of the packaging box 1 (1) When assembling the lid 10 of the body box 50 from which the upper part of the product 80 is exposed, the folding step 14 is fixed by fixing the folding piece 14 without using an adhesive such as hot melt. Since it can be formed, a dedicated machine for bonding is not required, and as a result, production costs can be reduced. In addition, since no adhesive is used, it is possible to easily handle small lot production by hand assembly (hand-folding with respect to the machine assembly). The sheet material 51 can be returned to.

（２）折込片１４を折返壁３Ｂと側壁１２Ｂとで挟着して固定する際、折込片５Ｂ、係止段部１６（第一係止片１６ａ、第二係止片１６ｂ）がストッパーとして機能して折返壁３Ｂの移動を規制するので、その結果、接着剤を使用しなくても、強固に折込片１４を折返壁３Ｂと側壁１２Ｂとで挟着して固定することができる。 (2) When the folding piece 14 is clamped and fixed between the folded wall 3B and the side wall 12B, the folding piece 5B and the locking step 16 (first locking piece 16a, second locking piece 16b) serve as a stopper. Since it functions and restricts the movement of the folded wall 3B, the folded piece 14 can be firmly clamped and fixed between the folded wall 3B and the side wall 12B without using an adhesive.

（３）身箱５０に収容する商品８０の露出する高さ（Ｔ４）が異なる場合であっても、係止段部１６の高さ（Ｔ３）を変更するだけ（一方向だけの変更）で極めて容易に対処することができ、その結果、包装箱１は、身箱５０から露出する高さの異なる様々な商品８０を容易に収容することが可能となる。 (3) Even if the exposed height (T4) of the product 80 accommodated in the body box 50 is different, it is only necessary to change the height (T3) of the locking step 16 (change only in one direction). As a result, the packaging box 1 can easily accommodate various products 80 exposed from the body box 50 with different heights.

（４）係止段部１６は、定位置に固定するためのロックが不要な構成、即ち折込片５Ｂにより第一係止片１６ａが側壁１２Ａ、１２Ｃに重合し、第二係止片１６ｂが折返壁３Ｂ及び折込片５Ｂに当接するように固定されているので、蓋１０の側壁１２Ａ、１２Ｂ、１２Ｃ、１２Ｄ等に穴を開けて係止段部１６をロックする必要がなく、その結果、美粧性に優れた包装箱１を形成することができる。 (4) The locking step 16 has a configuration that does not require a lock for fixing in place, that is, the first locking piece 16a is overlapped with the side walls 12A and 12C by the folding piece 5B, and the second locking piece 16b is Since it is fixed so as to contact the folding wall 3B and the folding piece 5B, there is no need to make a hole in the side wall 12A, 12B, 12C, 12D, etc. of the lid 10 to lock the locking step 16, and as a result, The packaging box 1 excellent in cosmetics can be formed.

以上、本考案の包装箱１を図面に基づいて説明してきたが、具体的な構成は実施形態に示したものに限定されるものではなく、本考案の要旨を逸脱しない範囲における変更や追加などがあっても本発明に含まれる。例えば、折込片５Ｂ、５Ｄは矩形状に形成したが、折込片５Ｂ、５Ｄの折返壁３Ｂ、３Ｄと反対側の辺は、直線以外の曲線で円弧状に形成するようにしてもよい。また、シート材５１は、段ボール以外の板紙であってもよい。 As mentioned above, although the packaging box 1 of this invention has been demonstrated based on drawing, a concrete structure is not limited to what was shown to embodiment, The change, addition, etc. in the range which does not deviate from the summary of this invention Is included in the present invention. For example, the folded pieces 5B and 5D are formed in a rectangular shape, but the side opposite to the folded walls 3B and 3D of the folded pieces 5B and 5D may be formed in an arc shape with a curve other than a straight line. Further, the sheet material 51 may be paperboard other than cardboard.
