Description

本発明は、紙製の包装容器に関するものである。 The present invention relates to a packaging container made of paper.

従来から、上面が開放された箱状の容器本体を、矩形筒状のカバーに出し入れ自在に収容し、包装対象物が収容された容器本体をカバーから筒軸方向に引き出して包装対象物を取り出せるようにした所謂スライドオープンパッケージ方式の包装容器が知られている。 Conventionally, a box-shaped container body with an open upper surface is housed in a rectangular tubular cover so that it can be freely taken in and out, and the container body containing the object to be packed can be pulled out from the cover in the cylinder axis direction to take out the object to be packed. Such a so-called slide open package type packaging container is known.

この種の包装容器では、容器本体の筒軸方向一方側の側面板と、当該側面板の上端から筒軸方向他方側に延びる引き出し片と、容器本体の底面板と引き出し片とを繋ぐ連結片と、から構成され、底面板と共に、カバーの筒軸方向と直交する矩形筒状をなす、「枕」と称される立体的な蓋部を、容器本体の筒軸方向一方側の端部に設けるのが一般的である。 In this type of packaging container, a side plate on one side in the cylinder axis direction of the container body, a drawer piece extending from the upper end of the side plate to the other side in the cylinder axis direction, and a connecting piece that connects the bottom plate of the container body and the drawer piece. And a bottom plate, together with the bottom plate, forming a rectangular tubular shape orthogonal to the tubular axis direction of the cover, a three-dimensional lid portion called "pillow" is attached to one end portion of the container body in the tubular axis direction. It is generally provided.

このような蓋部が設けられた包装容器では、引き出し片を押圧して蓋部を押し潰すと、引き出し片およびこれと重なった側面板がカバーの一方側の端部から突出するので、突出した引き出し片および側面板を摘んで引くことによって、容器本体をカバーから引き出せるようになっている。一方、包装対象物を取り出し終えれば、側面板を押圧して、カバーに対して容器本体を押し込むと、蓋部が立体的な形状に戻るので、かかる立体的な蓋部によってカバーの筒軸方向一方側の開口端が閉塞されるようになっている。 In a packaging container provided with such a lid portion, when the drawer piece is pressed to crush the lid portion, the drawer piece and the side plate overlapping with this project from one end portion of the cover, so The container body can be pulled out from the cover by pinching and pulling the pull-out piece and the side plate. On the other hand, when the object to be packaged is completely taken out, the side plate is pressed and the container body is pushed into the cover, so that the lid part returns to a three-dimensional shape. The open end on one side in the direction is closed.

もっとも、この種の包装容器は、通常コートボールで形成されており、その剛性が低いことから、閉塞時であるにも拘わらず、矩形筒状の蓋部が菱形筒状に変形し、蓋部とカバーとの間に隙間が生じて、包装対象物が容器本体から外部へ脱落するおそれがある。 However, since this type of packaging container is usually formed of coated balls and has low rigidity, the rectangular tubular lid portion is transformed into a rhombus tubular shape even when it is closed, and the lid portion is formed. There is a possibility that a gap is created between the container and the cover, and the object to be packaged falls off from the container body to the outside.

そこで、例えば特許文献１には、容器本体の正面板および背面板（底面板の両側縁部から上方に延びて対向する一対の側面板）の上端縁に切欠部を形成し、引き出し片の正面側端縁部および背面側端縁部を切欠部に載置することで、閉塞時における蓋部の変形を抑制することが開示されている。 Therefore, for example, in Patent Document 1, a front plate and a rear plate of the container body (a pair of side plates extending upward from both side edges of the bottom plate and facing each other) are provided with notches at the upper end edges thereof, and the front surface of the drawer piece is formed. It is disclosed that by placing the side edge portion and the back side edge portion in the cutout portion, the deformation of the lid portion when closed is suppressed.

特許４１２８９１８号公報Japanese Patent No. 4128918

ところで、上記「枕」と称される立体的な蓋部は、スライドオープンパッケージ方式の包装容器のみならず、通常の包装容器における蓋板およびフラップの代わりとして用いられることが、具体的には、有底矩形筒状の容器本体の開口端に設けられることがある。この場合には、引き出し片を押圧し、引き出し片と側面板とが重なるように蓋部を押し潰すことで、蓋部によって閉塞されていた開口端が開放されるので、開放された開口端から包装対象物を直接取り出すことになる。 By the way, the three-dimensional lid portion referred to as the above-mentioned "pillow" is used not only as a packaging container of a slide open package system but also as a substitute for a lid plate and a flap in an ordinary packaging container, specifically, It may be provided at the open end of the bottomed rectangular tubular container body. In this case, by pressing the drawer piece and crushing the lid part so that the drawer piece and the side plate overlap, the opening end closed by the lid part is opened, so that from the opened opening end The packaging object will be taken out directly.

しかしながら、立体的な蓋部を通常の包装容器に設けた場合には、以下のような問題が生じ得る。すなわち、上述の如く包装容器は通常コートボールで形成されていることから、矩形筒状をなすように折られていた蓋部の折り目には折り癖がついているため、引き出し片を押圧することで一旦押し潰されたとしても、押圧を止めれば、折り重ねられた蓋部が不完全ながら元の立体形状に戻ろうとする。このため、開口端の一部が蓋部によって塞がれ、包装対象物を取り出し難くなるという問題がある。 However, when the three-dimensional lid part is provided in an ordinary packaging container, the following problems may occur. That is, since the packaging container is usually formed of coated balls as described above, since the fold line of the lid portion that has been folded into a rectangular tubular shape has a crease, it is possible to press the drawer piece. Even if it is crushed once, if the pressing is stopped, the folded lid part will return to its original three-dimensional shape although it is incomplete. For this reason, there is a problem that a part of the open end is closed by the lid, and it becomes difficult to take out the object to be packaged.

この点、スライドオープンパッケージ方式の包装容器では、押し潰されることで突出した引き出し片等を摘んで容器本体をカバーから引き出すことから、蓋部が元の立体形状に戻っても支障はないとも思われる。しかしながら、カバーから容器本体を引き出すことなく、包装対象物をカバーから直接取り出そうとする消費者も想定されることから、スライドオープンパッケージ方式の包装容器においてもこのような問題は生じ得る。 In this regard, with the slide open package type packaging container, the drawer body that is crushed and squeezed out is pulled out to pull out the container body from the cover, so there is no problem even if the lid returns to its original three-dimensional shape. Be done. However, since it is assumed that some consumers try to take out the packaging object directly from the cover without pulling out the container body from the cover, such a problem may occur even in the packaging container of the slide open package system.

本発明はかかる点に鑑みてなされたものであり、その目的とするところは、立体的な蓋部を有する包装容器において、開封時に、折り重なるように変形させた蓋部が意図せず立体形状に戻るのを抑える技術を提供することにある。 The present invention has been made in view of such points, and an object thereof is to provide a packaging container having a three-dimensional lid portion, in which the lid portion deformed to be folded into a three-dimensional shape unintentionally when opened. It is to provide the technology to suppress the return.

前記目的を達成するため、本発明に係る包装容器では、開封時に、蓋部が立体形状に戻り難い形態を採るような折り目がつくように、蓋部を構成する部位に折り線を設けるようにしている。 In order to achieve the above-mentioned object, in the packaging container according to the present invention, a fold line is provided at a portion forming the lid portion so that the lid portion has a crease that does not easily return to a three-dimensional shape when opened. ing.

具体的には、本発明は、相対向する上面板および底面板と、相対向する一対の側面板とを有する矩形筒状の本体部と、当該本体部の一方の開口端を閉塞する蓋部と、を備える紙製の包装容器を対象としている。 Specifically, the present invention relates to a rectangular tubular main body having a top plate and a bottom plate facing each other, and a pair of side plates facing each other, and a lid for closing one open end of the main body. And a paper packaging container having

そして、上記蓋部は、上記底面板の筒軸方向の一方端と折り目を介して繋がる第１板と、当該一方端よりも筒軸方向他方側で上記底面板と折り目を介して繋がる第３板と、当該第１板および第３板とそれぞれ折り目を介して繋がる第２板とを有していて、これら第１板、第２板および第３板が、上記一対の側面板の対向方向から見て、上記底面板側に開いたコ字状をなす閉塞形態と、上記第１板と上記第２板とが重なり且つ上記第３板と上記底面板とが重なる開封形態と、を採るように構成されており、上記第２板または第３板には、上記開封形態を採った状態で、当該第２板または第３板における上記第１板と重なった部位が上記底面板よりも上記上面板から離れる側に反るように、上記底面板の一方端と重なる部位に折り線が設けられており、上記第１板、第２板および第３板が繋がる方向における、上記第３板の長さが上記第１板の長さよりも長いことを特徴とするものである。 The lid portion is connected to one end of the bottom plate in the cylinder axis direction via a fold, and a third plate is connected to the bottom plate on the other side of the bottom plate in the cylinder axis direction from the one end via a fold. A plate and a second plate connected to the first plate and the third plate via folds, respectively, and the first plate, the second plate and the third plate are in the facing direction of the pair of side plates. Seen from the above, there are adopted a closed configuration in which the U-shape is opened to the bottom plate side, and an unsealed configuration in which the first plate and the second plate overlap and the third plate and the bottom plate overlap. In the second plate or the third plate in the unsealed form, a portion of the second plate or the third plate that overlaps the first plate is more than the bottom plate. A fold line is provided in a portion overlapping with one end of the bottom plate so as to be curved toward the side away from the top plate, and the fold line is formed in the direction in which the first plate, the second plate, and the third plate are connected to each other. The length of the plate is longer than the length of the first plate .

なお、本発明において、「折り線」とは、例えば、切込み溝を入れたり、エンボス加工を施したりすること等により形成された、折り位置を明示するとともに紙を折り易くする線を意味する。また、本発明では、例えばこのような折り線に沿って、実際に折り曲げられた部位を「折り目」と称する。 In addition, in the present invention, the “folding line” means a line which is formed by, for example, forming a notch groove or performing embossing to clearly indicate the folding position and to facilitate folding of the paper. Further, in the present invention, a portion actually bent along such a fold line is referred to as a “fold”.

この構成によれば、第２板または第３板における底面板の一方端と重なる部位に折り線を設けることで、第２板または第３板における第１板と重なった部位を、底面板よりも上面板から離れる側に容易に反らせることができる。なお、以下では第２板に折り線を設けた場合について説明するが、第３板に折り線を設けた場合も同様である。 According to this configuration, by providing a fold line at a portion of the second plate or the third plate that overlaps with one end of the bottom plate, the portion of the second plate or the third plate that overlaps the first plate can be made smaller than the bottom plate. Can also be easily warped on the side away from the top plate. In the following, the case where the fold line is provided on the second plate will be described, but the same applies when the fold line is provided on the third plate.

ここで、折り重ねられた蓋部が不完全ながら元の立体形状に戻ろうとするような、折り目についた折り癖としては、以下の（１）〜（４）が挙げられる。すなわち、（１）底面板と第１板との折り目（仮に第１折り目という）については、第１板を底面板に対して上面板側に立ち上がらせようとする折り癖、（２）第１板と第２板との折り目（仮に第２折り目という）については、重なった第１板と第２板とを開かせようとする折り癖、（３）第２板と第３板との折り目（仮に第３折り目という）については、扁平状になった第２板と第３板とを閉じさせようとする折り癖、（４）第３板と底面板との折り目（仮に第４折り目という）については、第３板を底面板に対して上面板側に立ち上がらせようとする折り癖である。 Here, the following (1) to (4) may be mentioned as creases having creases in which the folded lid part is imperfect and tries to return to the original three-dimensional shape. That is, regarding (1) the fold line between the bottom plate and the first plate (tentatively referred to as the first fold), the crease that makes the first plate rise to the top plate side with respect to the bottom plate, and (2) the first fold. Regarding the fold line between the plate and the second plate (provisionally referred to as the second fold line), a crease that causes the overlapping first plate and the second plate to open, (3) fold line between the second plate and the third plate Regarding (temporarily called the third fold), a crease that tends to close the flat second plate and the third plate, (4) a fold between the third plate and the bottom plate (tentatively called the fourth fold) ) Is a habit of making the third plate stand up toward the top plate with respect to the bottom plate.

この点、本発明では、第２板における第１板と重なった部位を、底面板よりも上面板から離れる側に反らせるので、これに伴い第１板も上面板から離れる側に反る。これにより、（１）については、第１折り目は折り癖がついた方向とは反対側に折り曲げられるので、第１板が底面板に対して上面板側に立ち上がり難くなる。また、第２板における第１板と重なった部位が上面板から離れる側に反ると、第２板および第３板は筒軸方向で弓状に張った状態になる。これにより、（３）および（４）については、第３および第４折り目は扁平状に強く延ばされるので、扁平状になった第２板と第３板とが閉じたり、第３板が底面板に対して上面板側に立ち上がったりし難くなる。さらに、第２板における第１板と重なった部位が上面板から離れる側に反ると、第１板と第２板とが強く重なるので、（２）については、第２折り目が開き難くなる。 In this respect, in the present invention, the portion of the second plate that overlaps the first plate is bent toward the side away from the top plate rather than the bottom plate, and accordingly, the first plate also bends toward the side away from the top plate. Thus, in (1), since the first fold line is bent in the direction opposite to the direction in which the creases are formed, it is difficult for the first plate to rise to the top plate side with respect to the bottom plate. When the portion of the second plate that overlaps the first plate warps away from the upper plate, the second plate and the third plate are in a state of being stretched in an arcuate shape in the cylinder axis direction. As a result, in (3) and (4), the third and fourth folds are strongly extended in a flat shape, so that the flat second and third plates are closed or the third plate is bottomed. It is difficult for the face plate to stand on the side of the top plate. Furthermore, when the portion of the second plate that overlaps the first plate warps away from the top plate, the first plate and the second plate strongly overlap each other, and thus with respect to (2), the second fold is difficult to open. ..

加えて、第２板または第３板には、第１板と重なって反った状態を維持しようとする折り癖がつくことになる。 In addition, the second plate or the third plate has a crease to overlap with the first plate and maintain a warped state.

以上のように、第１〜第４折り目の折り癖が減殺されることと、第２板または第３板に第１板と重なって反った状態を維持しようとする折り癖がつくこととが相俟って、蓋部が立体形状に戻り難くなることから、開封時に、折り重なるように変形させた蓋部が意図せず立体形状に戻るのを抑えることができる。しかも、第１板よりも本体部またはカバー部に深く入り込む第３板の長さが、第１板の長さよりも長くなっていることから、換言すると、一対の側面板の対向方向から見て、蓋部が逆くさび状をなしていることから、上面板と底面板とによって当該第３板がしっかりと挟まれるので、本体部またはカバー部の開口端をしっかりと閉塞することができる。 As described above, the creases of the first to the fourth folds are reduced, and the creases of the second plate or the third plate overlap the first plate to maintain the warped state. Together, it is difficult for the lid portion to return to the three-dimensional shape, so that it is possible to prevent the lid portion deformed to be folded and folded back to the three-dimensional shape unintentionally when opening. Moreover, since the length of the third plate that penetrates deeper into the main body portion or the cover portion than the first plate is longer than the length of the first plate, in other words, when viewed from the facing direction of the pair of side surface plates. Since the lid part has an inverted wedge shape, the third plate is firmly sandwiched between the top plate and the bottom plate, so that the open end of the main body part or the cover part can be firmly closed.

また、本発明は、スライドオープンパッケージ方式の包装容器にも適用可能である。 The present invention is also applicable to a slide open package type packaging container.

すなわち、本発明は、相対向する上面板および底面板と、相対向する一対の側面板とを有する矩形筒状のカバー部と、上記底面板と重なりながら当該カバー部に出し入れ自在に収容される内板部と、当該カバー部の一方の開口端を閉塞する蓋部と、を備える紙製の包装容器をも対象としている。 That is, according to the present invention, a rectangular cylindrical cover part having a top plate and a bottom plate facing each other, and a pair of side plates facing each other, and a cover part that can be inserted into and removed from the cover part while overlapping the bottom plate. A paper packaging container including an inner plate portion and a lid portion that closes one open end of the cover portion is also targeted.

そして、上記蓋部は、上記内板部の筒軸方向の一方端と折り目を介して繋がる第１板と、当該一方端よりも筒軸方向他方側で上記内板部と折り目を介して繋がる第３板と、当該第１板および第３板とそれぞれ折り目を介して繋がる第２板とを有していて、これら第１板、第２板および第３板が、上記一対の側面板の対向方向から見て、上記内板部側に開いたコ字状をなす閉塞形態と、上記第１板と上記第２板とが重なり且つ上記第３板と上記内板部とが重なる開封形態と、を採るように構成されており、上記第２板または第３板には、上記開封形態を採った状態で、当該第２板または第３板における上記第１板と重なった部位が上記内板部よりも上記上面板から離れる側に反るように、上記内板部の一方端と重なる部位に折り線が設けられており、上記第１板、第２板および第３板が繋がる方向における、上記第３板の長さが上記第１板の長さよりも長いことを特徴とするものである。 The lid is connected to the first plate that is connected to one end of the inner plate in the cylinder axis direction via a fold, and is connected to the inner plate on the other side of the inner plate in the cylinder axis direction from the one end via the fold. It has a 3rd board and the 2nd board connected with the 1st board and the 3rd board via a crease, respectively, and these 1st board, the 2nd board, and the 3rd board are the above-mentioned pair of side plates. When viewed from the opposite direction, a closed configuration in which the U-shape is closed to the inner plate portion side, and an unsealed configuration in which the first plate and the second plate overlap and the third plate and the inner plate portion overlap each other And, in the second plate or the third plate, a portion of the second plate or the third plate that overlaps the first plate in the unsealed state is A fold line is provided at a portion overlapping with one end of the inner plate portion so as to be curved toward a side farther from the upper plate than the inner plate portion, and the first plate, the second plate, and the third plate are connected to each other. The length of the third plate in the direction is longer than the length of the first plate .

この構成によれば、第２板または第３板における内板部の一方端と重なる部位に折り線を設けることで、第２板または第３板における第１板と重なった部位を内板部よりも上面板から離れる側に容易に反らせることができる。これにより、スライドオープンパッケージ方式の包装容器においても、開封時に、折り重なるように変形させた蓋部が意図せず立体形状に戻るのを抑えることができる。したがって、スライドオープンパッケージ方式の包装容器においても、消費者は、カバー部から容器本体を引き出すことなく、包装対象物をカバー部から直接且つスムーズに取り出すことができる。 According to this structure, the folding line is provided at a portion of the second plate or the third plate that overlaps with one end of the inner plate portion, so that the portion of the second plate or the third plate that overlaps with the first plate becomes an inner plate portion. It can be bent more easily than the upper plate. As a result, even in the case of the slide open package type packaging container, it is possible to prevent the lid part deformed so as to be folded back from unintentionally returning to a three-dimensional shape when the package is opened. Therefore, even in the slide open package type packaging container, the consumer can directly and smoothly take out the packaging object from the cover portion without pulling out the container body from the cover portion.

また、第１板よりも本体部またはカバー部に深く入り込む第３板の長さが、第１板の長さよりも長くなっていることから、換言すると、一対の側面板の対向方向から見て、蓋部が逆くさび状をなしていることから、上面板と底面板とによって当該第３板がしっかりと挟まれるので、本体部またはカバー部の開口端をしっかりと閉塞することができる。 In addition , since the length of the third plate that goes deeper into the main body or the cover than the first plate is longer than the length of the first plate, in other words, when viewed from the facing direction of the pair of side plates. Since the lid part has an inverted wedge shape, the third plate is firmly sandwiched between the top plate and the bottom plate, so that the open end of the main body part or the cover part can be firmly closed.

以上、説明したように本発明に係る包装容器によれば、開封時に、折り重なるように変形させた蓋部が意図せず立体形状に戻るのを抑えることができる。 As described above, according to the packaging container of the present invention, it is possible to prevent the lid part deformed so as to be folded back from unintentionally returning to a three-dimensional shape when opened.

On the (the other side in the cylinder axis direction), an embossed portion 12b that extends in the left-right direction in FIG. 2 and is recessed on the back surface side in FIG. 2 is formed.

図２に示すように、第１板２１の幅（左右方向の幅）は、上面板１１および底面板１２の幅よりも大きく設定されている。また、第２板２２は、第１板２１側の部位が上面板１１および底面板１２の幅と同じ幅を有する矩形状に形成されている一方、第３板２３側の部位が先端（上側）に向かって窄む台形状に形成されている。さらに、第１板２１、第２板２２および第３板２３が連設される（繋がる）方向（図２の上下方向）における、第３板２３の長さは、第１板２１の長さよりも長く設定されている。 As shown in FIG. 2, the width of the first plate 21 (width in the left-right direction) is set larger than the widths of the top plate 11 and the bottom plate 12. Further, the second plate 22 is formed in a rectangular shape in which the portion on the side of the first plate 21 has the same width as the width of the top plate 11 and the bottom plate 12, while the portion on the side of the third plate 23 is the tip (upper side). ) Is trapezoidal. Furthermore, the length of the third plate 23 in the direction in which the first plate 21, the second plate 22, and the third plate 23 are continuously provided (connected) (the vertical direction in FIG. 2) is greater than the length of the first plate 21. Is also set long.

また、第２板２２には、第２折り線４２ａを挟んで第１折り線４１ａと線対称となる部位にエンボス加工によって折り線４５ａが形成されている。換言すると、第２折り線４２ａと折り線４５ａとの間隔は、第１板２１、第２板２２および第３板２３が連設される方向（以下、連設方向ともいう）における第１板２１の長さと等しくなっている。 In addition, the second plate 22 is formed with a folding line 45a by embossing at a portion which is line-symmetrical to the first folding line 41a with the second folding line 42a interposed therebetween. In other words, the distance between the second folding line 42a and the folding line 45a is the first plate in the direction in which the first plate 21, the second plate 22 and the third plate 23 are continuously arranged (hereinafter, also referred to as the continuous direction). It is equal to the length of 21.

−組み立て手順−
次に、以上のように構成された包装容器１の組み立て手順について説明する。 -Assembly procedure-
Next, a procedure for assembling the packaging container 1 configured as above will be described.

先ず、図２の展開図に従ってコートボールを打ち抜くとともに、図２の裏面が表側になるように反転させる。次いで、底面板１２と第１板２１とが直交し、第１板２１と第２板２２とが略直交し、且つ、第２板２２と第３板２３とが略直交するように、第１〜第３折り線４１ａ，４２ａ，４３ａをそれぞれ谷折りするとともに、第３板２３と糊代部２４とが直交するように、第４折り線４４ａを山折りし、接着剤を塗布した糊代部２４を底面板１２の内面に貼り付ける。これにより、底面板１２の筒軸方向の一方端と第１折り目４１を介して繋がる第１板２１と、当該一方端よりも筒軸方向他方側で底面板１２と第４折り目４４を介して繋がる第３板２３と、第１板２１および第３板２３とそれぞれ第２および第３折り目４２，４３を介して繋がる第２板２２とを有し、底面板１２側に開いたコ字状をなす立体的な蓋部２０が形成される（図３（ａ）参照）。なお、図３（ａ）および（ｂ）では、図を見易くするために、側面板１３，１４等を図示省略している。 First, the coated ball is punched out according to the development view of FIG. 2 and is inverted so that the back surface of FIG. 2 is the front side. Next, the bottom plate 12 and the first plate 21 are orthogonal to each other, the first plate 21 and the second plate 22 are substantially orthogonal to each other, and the second plate 22 and the third plate 23 are substantially orthogonal to each other. The first to third fold lines 41a, 42a, 43a are each valley-folded, and the fourth fold line 44a is mountain-folded so that the third plate 23 and the glue margin portion 24 are orthogonal to each other, and an adhesive is applied. The substitute portion 24 is attached to the inner surface of the bottom plate 12. Thereby, the first plate 21 connected to one end of the bottom plate 12 in the cylinder axis direction via the first fold 41, and the bottom plate 12 and the fourth fold 44 on the other side in the cylinder axis direction from the one end. It has a third plate 23 connected to it, and a second plate 22 connected to the first plate 21 and the third plate 23 via the second and third folds 42 and 43, respectively, and has a U-shape open to the bottom plate 12 side. The three-dimensional lid portion 20 forming the is formed (see FIG. 3A). In FIGS. 3(a) and 3(b), the side plates 13, 14 and the like are omitted for clarity.

次いで、側面板１４と上面板１１とが直交し、上面板１１と側面板１３とが直交し、側面板１３と底面板１２とが直交し、且つ、底面板１２と糊代部１６とが直交するように、折り線３１ａ，３２ａ，３３ａ，３４ａをそれぞれ谷折りする。そうして、糊代部１６および開閉体１１ｂに接着剤を塗布して、糊代部１６を側面板１４の内面に貼り付けるとともに、開閉体１１ｂを第２板２２の上面に貼り付ける。これにより、糊代部１６と貼着された側面板１４と、側面板１４と折り目３１を介して繋がる上面板１１と、上面板１１と折り目３２を介して繋がる側面板１３と、側面板１３および側面板１４とそれぞれ折り目３３，３４を介して繋がる底面板１２とを有し、蓋部２０を包む矩形筒が形成される。なお、包装対象物（図示せず）は、蓋部２０を包む矩形筒が形成された段階で箱詰め包装される。 Next, the side plate 14 and the top plate 11 are orthogonal to each other, the top plate 11 and the side plate 13 are perpendicular to each other, the side plate 13 and the bottom plate 12 are perpendicular to each other, and the bottom plate 12 and the glue margin portion 16 are The folding lines 31a, 32a, 33a, 34a are valley-folded so as to be orthogonal to each other. Then, an adhesive is applied to the paste margin portion 16 and the opening/closing body 11b to attach the glue margin portion 16 to the inner surface of the side surface plate 14 and the open/close body 11b to the upper surface of the second plate 22. As a result, the side surface plate 14 adhered to the glue margin portion 16, the upper surface plate 11 connected to the side surface plate 14 via the fold line 31, the side surface plate 13 connected to the upper surface plate 11 via the fold line 32, and the side surface plate 13 And the side face plate 14 and the bottom face plate 12 connected to the side face plate 14 via the folds 33 and 34, respectively, and a rectangular tube that wraps the lid portion 20 is formed. The object to be packaged (not shown) is box-packaged at the stage when the rectangular tube that wraps the lid 20 is formed.

次いで、折り線３５ａ，３７ａをそれぞれ谷折りして、フラップ１４ａ，１３ａを折畳む。そうして、折り線３６ａ，３８ａをそれぞれ谷折りするとともに、上側閉塞板１１ａの内面と底側閉塞板１２ａの外面とを接着剤で貼り合せる。これにより、側面板１４と折り目３５を介して繋がるフラップ１４ａと、上面板１１と折り目３６を介して繋がる上側閉塞板１１ａと、側面板１３と折り目３７を介して繋がるフラップ１３ａと、底面板１２と折り目３８を介して繋がる底側閉塞板１２ａとで構成される閉塞部１５が形成されて、包装容器１の組み立てが完了する。 Next, the folding lines 35a and 37a are valley-folded to fold the flaps 14a and 13a. Then, the folding lines 36a and 38a are each folded in a valley shape, and the inner surface of the upper blocking plate 11a and the outer surface of the bottom blocking plate 12a are bonded together with an adhesive. As a result, the flap 14a connected to the side plate 14 via the fold line 35, the upper closing plate 11a connected to the top plate 11 via the fold line 36, the flap 13a connected to the side plate 13 via the fold line 37, and the bottom plate 12 And the bottom side closing plate 12a connected to each other through the fold line 38 is formed, and the assembling of the packaging container 1 is completed.

−蓋部−
以上のように組み立てられた包装容器１においては、包装容器１を初めて開封する際に、開閉体１１ｂを押圧して切取ミシン線３９ａに沿って開閉体１１ｂを切り取ることで、蓋部２０がリクローズ時の閉塞形態と使用時の開封形態とを採ることが可能な状態となる。ここに、閉塞形態とは、図３（ａ）および図４（ａ）に示すように、第１板２１、第２板２２および第３板２３が、一対の側面板１３，１４の対向方向から見て、底面板１２側に開いたコ字状をなす立体的な形態をいう。一方、開封形態とは、図３（ｂ）および図４（ｂ）に示すように、第１板２１と第２板２２とが重なり且つ第３板２３と底面板１２とが重なる形態をいう。これら閉塞形態と開封形態とは、閉塞形態から、第２板２２に貼着された開閉体１１ｂを押圧して、立体形状の蓋部２０を押し潰すことで開封形態となる一方、開封形態から、第１板２１を起こすようにして第２板２２を本体部１０に押し込むことで閉塞形態となる、という関係にある。 -Lid-
In the packaging container 1 assembled as described above, when opening the packaging container 1 for the first time, the lid 20 is reclosed by pressing the opening/closing body 11b and cutting the opening/closing body 11b along the perforation machine line 39a. It becomes a state in which it is possible to adopt a closed form at the time of use and an open form at the time of use. Here, the closed form means that, as shown in FIGS. 3A and 4A, the first plate 21, the second plate 22, and the third plate 23 are in the facing direction of the pair of side surface plates 13 and 14. Seen from the bottom, it means a three-dimensional form having a U-shape open to the bottom plate 12 side. On the other hand, the unsealed form means a form in which the first plate 21 and the second plate 22 overlap with each other and the third plate 23 and the bottom plate 12 overlap with each other, as shown in FIGS. 3B and 4B. .. From the closed form, the closed form and the open form are the open form by pressing the opening/closing body 11b attached to the second plate 22 and crushing the three-dimensional lid portion 20 from the open form. , The second plate 22 is pushed into the main body 10 so that the first plate 21 is raised, and the second plate 22 is closed.

［閉塞形態］
先ず、第１板２１の幅は、上述の如く、上面板１１および底面板１２の幅よりも大きく設定されていることから、蓋部２０によって本体部１０の筒軸方向一方側の開口端を閉塞する際、側面板１３，１４の筒軸方向一方側の端縁に第１板２１の両側縁部が当接するので、蓋部２０が本体部１０に対して必要以上に押し込まれないようになっている。 [Blocking mode]
First, since the width of the first plate 21 is set to be larger than the widths of the top plate 11 and the bottom plate 12 as described above, the opening of one side of the main body 10 in the cylinder axis direction is closed by the lid 20. When closing, the both side edges of the first plate 21 come into contact with the ends of the side plates 13 and 14 on the one side in the cylinder axis direction, so that the lid part 20 is not pushed into the main body part 10 more than necessary. Is becoming

また、第２板２２は、上述の如く、第１板２１側の部位が上面板１１および底面板１２の幅と同じ幅を有する矩形状に形成されている一方、第３板２３側の部位が先端に向かって窄む台形状に形成されていることから、第１板２１を起こすようにして第２板２２を本体部１０に押し込む際、第２板２２を本体部１０に対して押し込み易くなっている。 Further, as described above, the second plate 22 is formed in a rectangular shape in which the portion on the first plate 21 side has the same width as the width of the top plate 11 and the bottom plate 12, while the portion on the third plate 23 side. Is formed into a trapezoidal shape that narrows toward the tip, so that when the second plate 22 is pushed into the main body 10 by raising the first plate 21, the second plate 22 is pushed into the main body 10. It's getting easier.

さらに、連設方向における第３板２３の長さは、第１板２１の長さよりも長く設定されていることから、換言すると、第３板２３の高さは、第１板２１の高さよりも高く設定されていることから、図４（ａ）に示すように、蓋部２０は筒軸方向に抜け出し難い逆くさび状をなして本体部１０に押し込まれることになる。これにより、上面板１１と底面板１２とによって第３板２３がしっかりと挟まれるので、本体部１０の開口端をしっかりと閉塞することができる。なお、第３板２３の長さと第１板２１の長さとの差は、実際には０．５ｍｍ程度であるが、図４（ａ）では、図を見易くするために、両者の差を誇張して示している。 Furthermore, since the length of the third plate 23 in the continuous installation direction is set longer than the length of the first plate 21, in other words, the height of the third plate 23 is greater than the height of the first plate 21. Since the height is also set to a high value, the lid portion 20 is pushed into the main body portion 10 in an inverted wedge shape that is hard to slip out in the cylinder axis direction, as shown in FIG. As a result, the third plate 23 is firmly sandwiched between the top plate 11 and the bottom plate 12, so that the open end of the main body portion 10 can be firmly closed. Note that the difference between the length of the third plate 23 and the length of the first plate 21 is actually about 0.5 mm, but in FIG. 4A, the difference between the two is exaggerated in order to make it easier to see. Is shown.

［開封形態］
開封形態では、第１板２１と第２板２２とが重なり且つ第３板２３と底面板１２とが重なるように蓋部２０が押し潰されるが、第１および第４折り目４１，４４には、第１板２１および第３板２３を底面板１２に対して上面板１１側にそれぞれ立ち上がらせようとする折り癖が、第２折り目４２には、重なった第１板２１と第２板２２とを開かせようとする折り癖が、第３折り目４３には、扁平状になった第２板２２と第３板２３とを閉じさせようとする折り癖が、それぞれついている。このため、第２板２２を押圧することで蓋部２０が一旦押し潰されたとしても、押圧を止めれば、折り重ねられた蓋部２０が不完全ながら元の立体形状に戻ろうとする。それ故、図４（ｃ）に示すように、開口端の一部が蓋部２０によって塞がれ、包装対象物を取り出すことが困難になる場合も想定される。 [Open form]
In the unsealed form, the lid portion 20 is crushed so that the first plate 21 and the second plate 22 overlap and the third plate 23 and the bottom plate 12 overlap, but the first and fourth folds 41, 44 do not , The first plate 21 and the third plate 23 have creases that make the first plate 21 and the third plate 23 stand up to the top plate 11 side with respect to the bottom plate 12, and the second fold 42 overlaps the first plate 21 and the second plate 22. And the third crease 43 has a crease that tends to close the flat second plate 22 and the third plate 23, respectively. Therefore, even if the lid 20 is crushed once by pressing the second plate 22, if the pressing is stopped, the folded lid 20 tries to return to the original three-dimensional shape although it is incomplete. Therefore, as shown in FIG. 4C, it may be assumed that a part of the open end is closed by the lid 20 and it becomes difficult to take out the object to be packaged.

そこで、本実施形態の包装容器１では、上述の如く、第２板２２に折り線４５ａを形成して、かかる折り線４５ａに沿って第２板２２を折り曲げることにより、図４（ｂ）に示すように、第２板２２における第１板２１と重なった部位を、底面板１２よりも上面板１１から離れる側に反らせるようにしている。より詳しくは、第２折り線４２ａと折り線４５ａとの間隔は、連設方向における第１板２１の長さと等しくなっていることから、折り線４５ａは、第２板２２における底面板１２の一方端と重なる部位に設けられていることになる。それ故、折り線４５ａに沿って第２板２２を折り曲げると、第２板２２における第１板２１と重なった部位と、第１板２１とが、底面板１２よりも上面板１１から離れる側に反ることになる。 Therefore, in the packaging container 1 of the present embodiment, as described above, the fold line 45a is formed on the second plate 22, and the second plate 22 is bent along the fold line 45a, as shown in FIG. As shown, the portion of the second plate 22 that overlaps with the first plate 21 is bent toward the side farther from the top plate 11 than the bottom plate 12. More specifically, since the distance between the second folding line 42a and the folding line 45a is equal to the length of the first plate 21 in the continuous installation direction, the folding line 45a is formed on the bottom plate 12 of the second plate 22. That is, it is provided at a portion overlapping with one end. Therefore, when the second plate 22 is bent along the fold line 45 a, the portion of the second plate 22 that overlaps the first plate 21 and the first plate 21 are farther from the top plate 11 than the bottom plate 12. Will be warped.

これにより、第１折り目４１は折り癖がついた方向とは反対側に折り曲げられるので、第１板２１が底面板１２に対して上面板１１側に立ち上がり難くなる。また、第２板２２における第１板２１と重なった部位が上面板１１から離れる側に反ると、第２板２２および第３板２３は筒軸方向で弓状に張った状態となる。これにより、第３および第４折り目４３，４４は扁平状に強く延ばされるので、扁平状になった第２板２２と第３板２３とが閉じたり、第３板２３が底面板１２に対して上面板１１側に立ち上がったりし難くなる。さらに、第２板２２における第１板２１と重なった部位が上面板１１から離れる側に反ると、第１板２１と第２板２２とが強く重なるので、第２折り目４２が開き難くなる。 As a result, the first fold line 41 is bent on the side opposite to the direction in which the creases are formed, so that it is difficult for the first plate 21 to rise to the top plate 11 side with respect to the bottom plate 12. When the portion of the second plate 22 that overlaps with the first plate 21 warps toward the side away from the upper plate 11, the second plate 22 and the third plate 23 are stretched in an arcuate shape in the cylinder axis direction. As a result, the third and fourth folds 43, 44 are strongly extended in a flat shape, so that the flat second plate 22 and the third plate 23 are closed, or the third plate 23 is removed from the bottom plate 12. It becomes difficult to stand up to the upper surface plate 11 side. Further, when the portion of the second plate 22 that overlaps with the first plate 21 warps toward the side away from the top plate 11, the first plate 21 and the second plate 22 strongly overlap with each other, making it difficult to open the second fold 42. ..

加えて、第２板２２における第１板２１と重なった部位を反らせるように第２板２２を折り曲げると、折り線４５ａを折り曲げた折り目４５にも、第１板２１と重なって反った状態を維持しようとする折り癖がつくことになる。 In addition, when the second plate 22 is bent so that the portion of the second plate 22 that overlaps the first plate 21 is warped, the fold line 45a at which the fold line 45a is bent also overlaps the first plate 21 and is warped. You will have a habit of maintaining it.

以上のように、第１〜第４折り目４１，４２，４３，４４の折り癖が減殺されることと、折り目４５に第２板２２が第１板２１と重なって反った状態を維持しようとする折り癖がつくこととが相俟って、蓋部２０が立体形状に戻り難くなる。したがって、開封時に、折り重なるように変形させた蓋部２０が意図せず立体形状に戻ることなく、図５に示すような状態が維持されるので、包装対象物を容易に取り出すことが可能となる。 As described above, the creases of the first to fourth folds 41, 42, 43, 44 are diminished, and the second plate 22 overlaps the first plate 21 at the fold line 45 to maintain the warped state. In combination with the tendency to fold, it becomes difficult for the lid 20 to return to the three-dimensional shape. Therefore, at the time of opening, the lid 20 deformed so as to be folded is not unintentionally returned to the three-dimensional shape, and the state as shown in FIG. 5 is maintained, so that the packaging target can be easily taken out. ..

なお、包装対象物を取り出す際には、底面板１２に糊付された糊代部２４の先端に包装対象物が引っ掛ることも想定されるが、本実施形態の包装容器１では、糊代部２４の先端近傍にエンボス部１２ｂが形成されていることから、図４（ｂ）に示すように、底面板１２と糊代部２４との段差が解消されるので、包装対象物をスムーズに取り出すことができる。 When the packaging target is taken out, the packaging target may be caught at the tip of the glue margin portion 24 attached to the bottom plate 12, but in the packaging container 1 of the present embodiment, the glue margin is Since the embossed portion 12b is formed near the tip of the portion 24, the step between the bottom plate 12 and the glue margin portion 24 is eliminated as shown in FIG. You can take it out.

−実施形態１の変形例−
本変形例は、包装容器２がスライドオープンパッケージ方式の包装容器である点が、上記実施形態１と異なるものである。以下、上記実施形態１と異なる部分を中心に説明する。 -Modification of Embodiment 1-
This modification is different from the first embodiment in that the packaging container 2 is a slide open packaging type packaging container. Hereinafter, the description will be focused on the parts different from the first embodiment.

図６は、本変形例に係る包装容器２を模式的に示す斜視図である。この包装容器２は、スライドオープンパッケージ方式の紙製の包装容器であり、図６に示すように、矩形筒状のカバー部５０と、カバー部５０に出し入れ自在に収容される内箱部６０と、カバー部５０の筒軸方向一方側の開口端を閉塞する蓋部７０と、を備えている。なお、展開図を図示省略するが、包装容器２も、実施形態１の包装容器１と同様に、コートボールを打ち抜いた後、折り線に沿って折り曲げるとともに、所定部分を糊付することによって組み立てられるものである。 FIG. 6 is a perspective view schematically showing the packaging container 2 according to this modification. The packaging container 2 is a slide-open packaging type paper packaging container, and as shown in FIG. 6, a rectangular tubular cover portion 50 and an inner box portion 60 that is housed in the cover portion 50 so as to be freely inserted and removed. And a lid portion 70 that closes the open end of the cover portion 50 on one side in the cylinder axis direction. Although the development view is not shown, the packaging container 2 is assembled by punching out the coated balls, bending them along the fold lines, and gluing a predetermined portion, as in the packaging container 1 of the first embodiment. It is what is done.

カバー部５０は、相対向する上面板５１および底面板５２と、相対向する一対の側面板５３，５４と、を有している。上面板５１の筒軸方向一方側の端部には、三角形状の切欠部５１ａが形成されており、この切欠部５１ａから蓋部７０の第２板７２を押圧することが可能となっている。なお、カバー部５０の内寸は、カバー部５０に対して内箱部６０を円滑に摺動することができるように、内箱部６０の外寸に対応して設定されている。 The cover part 50 has a top plate 51 and a bottom plate 52 facing each other, and a pair of side plates 53, 54 facing each other. A triangular notch 51a is formed at an end of the upper surface plate 51 on one side in the cylinder axis direction, and the second plate 72 of the lid 70 can be pressed from the notch 51a. .. The inner size of the cover part 50 is set to correspond to the outer size of the inner box part 60 so that the inner box part 60 can slide smoothly with respect to the cover part 50.

内箱部６０は、底面板６２と、相対向する一対の側面板６３，６４と、軸方向他方側の端部で底面板６２および側面板６３，６４と繋がる閉塞板６５と、を有していて、蓋部７０と共に、上面が開放された箱状体を形成している。なお、閉塞板６５は、側面板６３，６４の軸方向他方側の端部に設けられたフラップ（図示せず）と接着剤で貼り合わされている。この内箱部６０は、底面板６２がカバー部５０の底面板５２と重なりながら、カバー部５０に出し入れ自在に収容される。これにより、本変形例では、内箱部６０の底面板６２が、本発明にいう「底面板と重なりながらカバー部に出し入れ自在に収容される内板部」に対応している。 The inner box part 60 has a bottom plate 62, a pair of side plates 63 and 64 facing each other, and a closing plate 65 connected to the bottom plate 62 and the side plates 63 and 64 at the other end in the axial direction. In addition, together with the lid portion 70, a box-shaped body having an open upper surface is formed. The closing plate 65 is attached to the flaps (not shown) provided at the ends of the side plates 63 and 64 on the other side in the axial direction with an adhesive. The inner box part 60 is housed in the cover part 50 so that the bottom plate 62 overlaps with the bottom plate 52 of the cover part 50 so that the inner box part 60 can be freely taken in and out. As a result, in the present modification, the bottom plate 62 of the inner box portion 60 corresponds to the "inner plate portion that is housed in the cover portion so as to be freely inserted and removed while overlapping the bottom plate" in the present invention.

蓋部７０は、上記実施形態１の蓋部２０が底面板１２の上側に、順次折り線を介して連設された第１板２１、第２板２２、第３板２３および糊代部２４によって構成されていたのと同様に、底面板６２の筒軸方向一方側に、順次折り線を介して連設された第１板７１、第２板７２、第３板７３および糊代部７４によって構成されている。そうして、折り線をそれぞれ折るとともに、接着剤を塗布した糊代部７４を底面板６２の内面に貼り付けることで、底面板（内板部）６２の筒軸方向の一方端と第１折り目８１を介して繋がる第１板７１と、当該一方端よりも筒軸方向他方側で底面板６２と第４折り目８４を介して繋がる第３板７３と、第１板７１および第３板７３とそれぞれ第２および第３折り目８２，８３を介して繋がる第２板７２とを有し、底面板６２側に開いたコ字状をなす立体的な蓋部７０が形成される。 The lid part 70 includes a first plate 21, a second plate 22, a third plate 23, and a glue margin part 24 in which the lid part 20 of the first embodiment is continuously provided above the bottom plate 12 via folding lines. The first plate 71, the second plate 72, the third plate 73, and the glue margin portion 74, which are continuously provided on one side in the cylinder axis direction of the bottom plate 62 via folding lines in the same manner as the above. It is composed by. Then, the folding lines are respectively folded and the glue margin portion 74 coated with the adhesive is attached to the inner surface of the bottom plate 62, so that one end of the bottom plate (inner plate portion) 62 in the cylinder axis direction and the first end. The first plate 71 connected through the fold 81, the third plate 73 connected through the fourth fold 84 with the bottom plate 62 on the other side in the cylinder axis direction from the one end, and the first plate 71 and the third plate 73. And a second plate 72 connected through the second and third folds 82 and 83, respectively, and a three-dimensional lid 70 having a U-shape that is open toward the bottom plate 62 is formed.

この蓋部７０は、第１板７１、第２板７２および第３板７３が、一対の側面板５３，５４の対向方向から見て、底面板６２側に開いたコ字状をなす閉塞形態と、第１板７１と第２板７２とが重なり且つ第３板７３と底面板６２とが重なる開封形態と、を採るように構成されている。これら閉塞形態と開封形態とは、切欠部５１ａから第２板７２を押圧して、立体形状の蓋部７０を押し潰すことで、閉塞形態から開封形態となる一方、開封形態から、第１板７１を起こすようにして内箱部６０をカバー部５０に収容することで閉塞形態となる、という関係にある。 In the lid portion 70, the first plate 71, the second plate 72, and the third plate 73 have a U-shape in which the first plate 71, the second plate 72, and the third plate 73 are open to the bottom plate 62 side when viewed from the facing direction of the pair of side plates 53 and 54. And an unsealed form in which the first plate 71 and the second plate 72 overlap and the third plate 73 and the bottom plate 62 overlap. The closed form and the open form are changed from the closed form to the open form by pressing the second plate 72 from the cutout portion 51a to crush the three-dimensional lid 70, while the open form is changed to the first plate. When the inner box portion 60 is housed in the cover portion 50 such that the inner box portion 71 is raised, a closed configuration is obtained.

また、第１板７１の幅は、カバー部５０の上面板５１および底面板５２の幅よりも大きく設定されており、これにより、内箱部６０をカバー部５０に収容する際、側面板５３，５４の筒軸方向一方側の端縁に第１板７１の両側縁部が当接するので、内箱部６０がカバー部５０に対して必要以上に押し込まれないようになっている。 In addition, the width of the first plate 71 is set to be larger than the widths of the top plate 51 and the bottom plate 52 of the cover part 50, so that when the inner box part 60 is accommodated in the cover part 50, the side plate 53. Since both side edges of the first plate 71 abut on one end of the first axial direction of the cylinder 54 in the cylinder axis direction, the inner box portion 60 is prevented from being pushed into the cover portion 50 more than necessary.

さらに、第２板７２は、その第１板７１側の部位が底面板６２の幅よりも大きい幅を有しており、閉塞形態では、当該第１板７１側の部位の幅方向両端部が、一対の側面板６３，６４の上縁に形成された切欠部（図示せず）に乗り上げて載置されるようになっている。これにより、消費者が第２板７２を押圧して蓋部７０を押し潰さない限り、蓋部７０の閉塞形態が維持されることから、包装対象物が脱落するのを抑えることができる。 Furthermore, the second plate 72 has a width on the first plate 71 side that is larger than the width of the bottom plate 62, and in the closed configuration, both widthwise ends of the first plate 71 side are located. A pair of side plates 63, 64 are mounted on a notch (not shown) formed on the upper edges of the side plates 63, 64. As a result, unless the consumer presses the second plate 72 to crush the lid 70, the closed form of the lid 70 is maintained, and thus it is possible to prevent the packaging object from falling off.

加えて、第２板７２には、開封形態を採った状態で、第２板７２における第１板７１と重なった部位が底面板６２よりも上面板５１から離れる側に反るように、底面板６２の筒軸方向の一方端と重なる部位に折り線８５ａが設けられている。そうして、第２板７２を折り線８５ａに沿って折り曲げて第２板７２における第１板７１と重なった部位を反らせると、上記実施形態１と同様に、第１〜第４折り目８１，８２，８３，８４の折り癖が減殺されることと、折り線８５ａを折り曲げた折り目に折り癖がつくこととが相俟って、蓋部７０が立体形状に戻り難くなる。したがって、開封時に、折り重なるように変形させた蓋部７０が意図せず立体形状に戻るのを抑えることができる。 In addition, the bottom of the second plate 72 is formed so that the portion of the second plate 72 that overlaps the first plate 71 is warped toward the side away from the top plate 51 rather than the bottom plate 62 in the unsealed state. A fold line 85a is provided at a portion overlapping with one end of the face plate 62 in the cylinder axis direction. Then, when the second plate 72 is bent along the fold line 85a and the portion of the second plate 72 that overlaps the first plate 71 is warped, the first to fourth folds 81, The fact that the folding habits of 82, 83, 84 are reduced and the folding creases formed by folding the folding line 85a are combined to make it difficult for the lid portion 70 to return to the three-dimensional shape. Therefore, when the package is opened, it is possible to prevent the lid 70 deformed so as to be folded back from unintentionally returning to a three-dimensional shape.

以上のように、本変形例によれば、スライドオープンパッケージ方式の包装容器２においても、カバー部５０から内箱部６０を引き出すことなく、包装対象物をカバー部５０から直接且つスムーズに取り出すことができる。 As described above, according to this modification, even in the packaging container 2 of the slide open package system, the object to be packaged can be directly and smoothly taken out from the cover part 50 without pulling out the inner box part 60 from the cover part 50. You can

（実施形態２）
本実施形態は、開封形態を維持するための折り線１２５ａが第２板１０２ではなく第３板１０３に設けられている点が、上記実施形態１と異なるものである。以下、上記実施形態１と異なる部分を中心に説明する。 (Embodiment 2)
The present embodiment is different from the first embodiment in that the folding line 125a for maintaining the unsealed form is provided on the third plate 103 instead of the second plate 102. Hereinafter, the description will be focused on the parts different from the first embodiment.

図７は、本実施形態に係る包装容器３を模式的に示す斜視図であり、図８は、包装容器３の展開図である。この包装容器３は、相対向する上面板９１および底面板９２と、相対向する一対の側面板９３，９４と、筒軸方向他方側の端部を閉塞する閉塞部９５と、を有する有底矩形筒状の本体部９０と、当該本体部９０の筒軸方向一方側の開口端を閉塞する蓋部１００と、を備えている。なお、図８は、本体部９０の外面が図の表側となるように記載されている。 FIG. 7 is a perspective view schematically showing the packaging container 3 according to the present embodiment, and FIG. 8 is a development view of the packaging container 3.

図８に示す展開図において、矩形状の側面板９４の左側には略矩形状の上面板９１が、上面板９１の左側には矩形状の側面板９３が、側面板９３の左側には矩形状の底面板９２が、底面板９２の左側には糊代部９６が、それぞれ折り線１１１ａ，１１２ａ，１１３ａ，１１４ａを介して連設されている。また、側面板９４、上面板９１、側面板９３および底面板９２の下側には、閉塞部９５を構成するフラップ９４ａ、上側閉塞板９１ａ、フラップ９３ａおよび底側閉塞板９２ａがそれぞれ折り線１１５ａ，１１６ａ，１１７ａ，１１８ａを介して連設されている。さらに、底面板９２の上側には第１板１０１が、第１板１０１の上側には第２板１０２が、第２板１０２の上側には第３板１０３が、第３板１０３の上側には糊代部１０４が、それぞれ第１折り線１２１ａ，第２折り線１２２ａ，第３折り線１２３ａ，第４折り線１２４ａを介して連設されている。上面板９１の上端部には、切取ミシン線１１９ａを介して開閉体９１ｂが形成されている。 -Exploded view-
In the development view shown in FIG. 8, a substantially rectangular upper surface plate 91 is provided on the left side of the rectangular side surface plate 94, a rectangular side surface plate 93 is provided on the left side of the upper surface plate 91, and a rectangular shape is provided on the left side of the side surface plate 93. A bottom plate 92 having a shape and a margin portion 96 on the left side of the bottom plate 92 are continuously provided via folding lines 111a, 112a, 113a, 114a, respectively. Below the side surface plate 94, the top surface plate 91, the side surface plate 93 and the bottom surface plate 92, the flap 94a, the upper side closing plate 91a, the flap 93a and the bottom side closing plate 92a which form the closing portion 95 are folded lines 115a. , 116a, 117a, 118a are connected in series. Further, the first plate 101 is above the bottom plate 92, the second plate 102 is above the first plate 101, the third plate 103 is above the second plate 102, and the third plate 103 is above the third plate 103. The glue margin portion 104 is continuously provided via the first folding line 121a, the second folding line 122a, the third folding line 123a, and the fourth folding line 124a. An opening/closing body 91b is formed on the upper end portion of the upper surface plate 91 via a cut-out sewing wire 119a.

図８に示すように、第１板１０１の幅は、蓋部１００が本体部９０に対して必要以上に押し込まれないように、上面板９１および底面板９２の幅よりも大きく設定されている。また、第２板１０２を本体部９０に対して押し込み易くなるように、第２板１０２は、第１板１０１側の部位が上面板９１および底面板９２の幅と同じ幅を有する矩形状に形成されている一方、第３板１０３側の部位が先端に向かって窄む台形状に形成されている。さらに、本体部９０の開口端をしっかりと閉塞することができるように、第１板１０１、第２板１０２および第３板１０３が連設される方向（以下、連設方向ともいう）における、第３板１０３の長さは、第１板１０１の長さよりも長く設定されている。 As shown in FIG. 8, the width of the first plate 101 is set to be larger than the widths of the top plate 91 and the bottom plate 92 so that the lid 100 is not pushed into the main body 90 more than necessary. .. Further, the second plate 102 has a rectangular shape in which a portion on the side of the first plate 101 has the same width as that of the top plate 91 and the bottom plate 92 so that the second plate 102 can be easily pushed into the main body 90. On the other hand, the portion on the third plate 103 side is formed in a trapezoidal shape that narrows toward the tip. Furthermore, in the direction in which the first plate 101, the second plate 102, and the third plate 103 are continuously arranged (hereinafter, also referred to as the continuous direction) so that the open end of the main body portion 90 can be firmly closed, The length of the third plate 103 is set longer than the length of the first plate 101.

また、第３板１０３には、第２折り線１２２ａを挟んで第１折り線１２１ａと線対称となる部位にエンボス加工によって折り線１２５ａが形成されている。換言すると、第２折り線１２２ａと折り線１２５ａとの間隔は、連設方向における第１板１０１の長さと等しくなっている。 In addition, a folding line 125a is formed on the third plate 103 by embossing at a portion which is line-symmetrical to the first folding line 121a with the second folding line 122a interposed therebetween. In other words, the distance between the second folding line 122a and the folding line 125a is equal to the length of the first plate 101 in the continuous direction.

−組み立て手順−
次に、以上のように構成された包装容器３の組み立て手順について説明する。先ず、図８の展開図に従ってコートボールを打ち抜くとともに、図８の裏面が表側になるように反転させる。次いで、第１〜第３折り線１２１ａ，１２２ａ，１２３ａをそれぞれ谷折りするとともに第４折り線１２４ａを山折りし、糊代部１０４を底面板９２の内面に接着剤で貼り付ける。これにより、底面板９２の筒軸方向の一方端と第１折り目１２１を介して繋がる第１板１０１と、当該一方端よりも筒軸方向他方側で底面板９２と第４折り目１２４を介して繋がる第３板１０３と、第１板１０１および第３板１０３とそれぞれ第２および第３折り目１２２，１２３を介して繋がる第２板１０２とを有し、底面板９２側に開いたコ字状をなす立体的な蓋部１００が形成される（図９（ａ）参照）。 -Assembly procedure-
Next, a procedure for assembling the packaging container 3 configured as above will be described. First, the coated ball is punched out according to the development view of FIG. 8 and is inverted so that the back surface of FIG. 8 is the front side. Next, the first to third folding lines 121a, 122a, 123a are valley-folded and the fourth folding line 124a is mountain-folded, and the glue margin portion 104 is attached to the inner surface of the bottom plate 92 with an adhesive. As a result, the first plate 101 connected to one end of the bottom plate 92 in the cylinder axis direction via the first fold 121, and the bottom plate 92 and the fourth fold 124 on the other side in the cylinder axis direction from the one end. It has a third plate 103 connected to it, and a second plate 102 connected to the first plate 101 and the third plate 103 via the second and third folds 122 and 123, respectively, and has a U-shape open to the bottom plate 92 side. The three-dimensional lid portion 100 forming the is formed (see FIG. 9A).

次いで、折り線１１１ａ，１１２ａ，１１３ａ，１１４ａをそれぞれ谷折りし、糊代部９６を側面板９４の内面に接着剤で貼り付けるとともに、開閉体９１ｂを第２板１０２の上面に接着剤で貼り付ける。これにより、糊代部９６と貼着された側面板９４と、側面板９４と折り目１１１を介して繋がる上面板９１と、上面板９１と折り目１１２を介して繋がる側面板９３と、側面板９３および側面板９４とそれぞれ折り目１１３，１１４を介して繋がる底面板９２とを有し、蓋部１００を包む矩形筒が形成される。 Next, the folding lines 111a, 112a, 113a, 114a are respectively valley-folded, the glue margin portion 96 is attached to the inner surface of the side surface plate 94 with an adhesive, and the opening/closing body 91b is attached to the upper surface of the second plate 102 with an adhesive. wear. As a result, the side surface plate 94 attached to the glue margin portion 96, the upper surface plate 91 connected to the side surface plate 94 through the fold line 111, the side surface plate 93 connected to the upper surface plate 91 through the fold line 112, and the side surface plate 93. And a side plate 94 and a bottom plate 92 connected to the side plates 94 via folds 113 and 114, respectively, and a rectangular tube that encloses the lid 100 is formed.

次いで、折り線１１５ａ，１１７ａをそれぞれ谷折りして、フラップ９４ａ，９３ａを折畳み、折り線１１６ａ，１１８ａをそれぞれ谷折りするとともに、上側閉塞板９１ａの内面と底側閉塞板９２ａの外面とを接着剤で貼り合せる。これにより、側面板９４、上面板９１、側面板９３および底面板９２とそれぞれ折り目１１５，１１６，１１７，１１８を介して繋がるフラップ９４ａ、上側閉塞板９１ａ、フラップ９３ａおよび底側閉塞板９２ａで構成される閉塞部９５が形成されて、包装容器３の組み立てが完了する。 Next, the fold lines 115a and 117a are valley-folded, the flaps 94a and 93a are folded, the fold lines 116a and 118a are valley-folded, and the inner surface of the upper blocking plate 91a and the outer surface of the bottom blocking plate 92a are bonded. Glue together. Thereby, the side plate 94, the top plate 91, the side plate 93, and the bottom plate 92 are constituted by the flap 94a, the upper closing plate 91a, the flap 93a, and the bottom closing plate 92a which are connected via the folds 115, 116, 117, and 118, respectively. The closed portion 95 is formed to complete the assembly of the packaging container 3.

−蓋部−
以上のように組み立てられた包装容器３においては、包装容器３を初めて開封する際に、第２板１０２と糊付された開閉体９１ｂを押圧して切取ミシン線１１９ａに沿って切り取る。これにより、蓋部１００は、図９（ａ）に示すように、第１板１０１、第２板１０２および第３板１０３が、一対の側面板９３，９４の対向方向から見て、底面板９２側に開いたコ字状をなす閉塞形態と、図９（ｂ）に示すように、第１板１０１と第２板１０２とが重なり且つ第３板１０３と底面板９２とが重なる開封形態と、を採ることが可能な状態となる。 -Lid-
In the packaging container 3 assembled as described above, when opening the packaging container 3 for the first time, the second plate 102 and the opening/closing body 91b pasted with the adhesive are pressed and cut out along the perforation perforation line 119a. As a result, in the lid portion 100, as shown in FIG. 9A, the first plate 101, the second plate 102, and the third plate 103 are bottom plate when viewed from the facing direction of the pair of side surface plates 93, 94. A closed form having a U-shape that is open to the side of 92 and an open form in which the first plate 101 and the second plate 102 overlap and the third plate 103 and the bottom plate 92 overlap as shown in FIG. 9B. It becomes possible to take and.

ここで、上記実施形態１と同様に、第２板１０２に折り線を形成して底面板９２よりも上面板９１から離れる側に反らせれば、蓋部１００が立体形状に戻るのを抑制することができる。しかしながら、本実施形態のように包装容器３の厚さが相対的に厚い場合、換言すると、連設方向における第１板１０１の長さが相対的に長い場合に、第２板１０２に折り線を形成しようとすると、必然的に第２板１０２が長くなり、その結果、本体部９０における蓋部１００の占める割合が大きくなり過ぎて、包装可能な包装対象物の数が少なくなるという問題がある。 Here, similarly to the first embodiment, if a folding line is formed on the second plate 102 and the second plate 102 is bent toward the side farther from the top plate 91 than the bottom plate 92, the lid 100 is prevented from returning to a three-dimensional shape. be able to. However, when the thickness of the packaging container 3 is relatively thick as in this embodiment, in other words, when the length of the first plate 101 in the connecting direction is relatively long, the fold line is formed on the second plate 102. However, there is a problem in that the second plate 102 inevitably becomes long, and as a result, the proportion of the lid portion 100 in the main body portion 90 becomes too large, and the number of wrapping target objects decreases.

そこで、本実施形態の包装容器３では、上述の如く、第３板１０３に折り線１２５ａを形成して、かかる折り線１２５ａに沿って第３板１０３を折り曲げることにより、図４（ｂ）に示すように、第２板１０２と共に第３板１０３における第１板１０１と重なった部位を、底面板９２よりも上面板９１から離れる側に反らせるようにしている。より詳しくは、第２折り線１２２ａと折り線１２５ａとの間隔は、連設方向における第１板１０１の長さと等しくなっていることから、折り線１２５ａは、第３板１０３における底面板９２の一方端と重なる部位に設けられていることになる。それ故、折り線１２５ａに沿って第３板１０３を折り曲げると、第３板１０３における第１板１０１と重なった部位と第１板１０１と第２板１０２とが、底面板９２よりも上面板９１から離れる側に反ることになる。 Therefore, in the packaging container 3 of the present embodiment, as described above, the folding line 125a is formed on the third plate 103, and the third plate 103 is bent along the folding line 125a, as shown in FIG. As shown, the portion of the third plate 103, which overlaps with the second plate 102, overlapping the first plate 101 is bent toward the side farther from the top plate 91 than the bottom plate 92. More specifically, since the interval between the second folding line 122a and the folding line 125a is equal to the length of the first plate 101 in the continuous installation direction, the folding line 125a corresponds to the bottom plate 92 of the third plate 103. That is, it is provided at a portion overlapping with one end. Therefore, when the third plate 103 is bent along the fold line 125a, the portion of the third plate 103 overlapping the first plate 101, the first plate 101, and the second plate 102 become a top plate rather than a bottom plate 92. It will warp to the side away from 91.

このように、第３板１０３を折り曲げて第３板１０３における第１板１０１と重なった部位を反らせると、上記実施形態１と同様に、第１〜第４折り目１２１，１２２，１２３，１２４の折り癖が減殺されることと、折り線１２５ａを折り曲げた折り目１２５に折り癖がつくこととが相俟って、蓋部１００が立体形状に戻り難くなる。これにより、本実施形態の包装容器３では、開封時に、折り重なるように変形させた蓋部１００が意図せず立体形状に戻ることなく、図１０に示すような状態が維持されるので、包装対象物を容易に取り出すことが可能となる。 In this way, when the third plate 103 is bent and the portion of the third plate 103 that overlaps the first plate 101 is warped, the first to fourth folds 121, 122, 123, and 124 are formed in the same manner as in the first embodiment. The creases are reduced and the crease 125 formed by folding the fold line 125a has a crease, which makes it difficult for the lid 100 to return to the three-dimensional shape. As a result, in the packaging container 3 of the present embodiment, the lid 100 deformed so as to be folded does not unintentionally return to the three-dimensional shape when opened, and the state as shown in FIG. 10 is maintained. It becomes possible to take out the object easily.
