Description

本発明は、収容物の取出口を開閉する蓋を必要に応じて開状態に維持できるようにした紙容器に関するものである。 The present invention relates to a paper container in which a lid that opens and closes an outlet for stored items can be maintained in an open state as necessary.

小物品を複数個収納する収納体として取出口を蓋部材で開け閉めする容器が従来から知られている。そして、粒菓子や個包装された菓子を複数個収納して手持ちできる程度の商品形態とした菓子容器などにおいては、収容物を一個ずつ取り出す際、蓋部材に邪魔されることなくその取出口を必要に応じて開放させておけば取り出しが容易になるため、一枚のブランクを組み上げた紙箱において、取出口を開閉可能に覆う蓋板を必要に応じてその起立状態を維持させることができるようにしたものが提案されている。 2. Description of the Related Art Conventionally, a container that opens and closes an outlet with a lid member is known as a storage body that stores a plurality of small articles. And in a confectionery container etc. made into a product form that can hold and hold a plurality of grain confectionery and individually packaged confectionery, when taking out the contents one by one, the outlet is not disturbed by the lid member If it is opened as needed, it will be easy to take out, so in a paper box assembled with a single blank, it is possible to maintain the standing state of the cover plate that can open and close the outlet as necessary What has been proposed is proposed.

例えば特許文献１や特許文献２に示されているように、このような包装用の紙箱は、上板と側板と底板からなる箱胴部の両端部分を前記上板、側板、底板に連接されたフラップの重ね合わせで閉じて箱本体を直方体状とし、取出口を位置させた前記上面に蓋板を重ね合わせている。蓋板は取出口を開閉可能に覆うものであり、予め上面に取出口が形成されている紙箱（特許文献２）があるとともに、その上面の取出口を切り取り線で区画形成された閉鎖板で閉鎖しておき、蓋板の引き起こしで切り取り線が破断して蓋板とともに閉鎖板が引き起こされて取出口から分離することで、開いた取出口が形成されるようにした紙箱（特許文献１）もある。
そして、蓋板の起立状態を維持させるべく、その蓋板を上板上面に貼り付けして固定する蓋板支持部とこの蓋板支持部に折り罫を介して連接されてその折り罫を中心に回動可能な蓋板本体とからなるものとしていて、折り罫位置から前記蓋板支持部側に凸の突片を蓋板本体に前記折り罫を介することなく連続して設けている。さらに、蓋板本体を上板から引き起こして折り罫を中心にした開き方向の回動を手作業で行ない、前記突片が上板の上面を押し下げてその上板上で回動しながら取出口側に摺接移動し、蓋板本体が後倒した時点で突片から押し下げを受けなくなった上板が元の位置に戻り、そして、その上板に前記突片が乗って折り罫の位置での折り戻りの作用を受けて前記突片が上板に当接し、手操作で蓋板を閉じ方向に回動させないかぎり突片が移動しないようにすることで、蓋板本体の後倒した状態が保たれることを目的にしたものであった。
特開平１１−３２１８５５号公報特許第３９６０５１４号公報 For example, as shown in Patent Document 1 and Patent Document 2, such a paper box for packaging is connected to the upper plate, the side plate, and the bottom plate at both ends of the box body portion including the upper plate, the side plate, and the bottom plate. The box body is formed in a rectangular parallelepiped shape by overlapping the flaps, and the cover plate is overlaid on the upper surface where the outlet is located. The cover plate covers the outlet in an openable and closable manner, and there is a paper box (Patent Document 2) in which the outlet is previously formed on the upper surface, and the upper plate is a closing plate that is partitioned by a cut line. A paper box that is closed, and the cut line is broken by the trigger of the lid plate, and the closure plate is caused together with the lid plate to separate from the outlet, so that an open outlet is formed (Patent Document 1) There is also.
Then, in order to maintain the standing state of the lid plate, a lid plate support portion for adhering and fixing the lid plate to the upper surface of the upper plate, and the lid plate support portion are connected to each other via a fold rule to center the crease rule. And a projecting piece projecting from the folding line position to the lid plate support part side is continuously provided on the lid plate body without the folding line. Further, the lid plate body is raised from the upper plate and manually rotated in the opening direction around the crease, and the protruding piece pushes down the upper surface of the upper plate and rotates on the upper plate, thereby removing the outlet. When the lid plate body is moved backward, the upper plate that has not been pushed down from the protruding piece returns to the original position, and the protruding piece rides on the upper plate at the position of the crease. The protruding piece comes into contact with the upper plate under the action of folding back, and the protruding piece does not move unless the lid plate is manually rotated in the closing direction. It was intended to be maintained.

しかしながら、上述した従来の紙箱では、蓋板本体を回動させるときに突片の先端が上板上面に摺接するものであることから、程よい力具合いで蓋板を回動でき、かつその蓋板の起立も必要に応じて安定して行なえる紙箱を得ることは、紙厚や紙の硬さ、上板上面の滑り性などの条件も考慮する必要があるので非常に困難である。
そのため、蓋板の回動操作性を或る程度犠牲にして、蓋板の初期開封時には確実に後倒状態が維持できるように突片の長さを長くしているのが現状であるが、蓋板の回動操作を繰り返すと、早期に突片先端が潰れたりその突片が折れ曲がってしまい、蓋板の起立状態が保たれずに取出口側にかぶさって収容物の取り出しに蓋板が邪魔になるという問題が生じていた。
そこで本発明は上記事情に鑑み、蓋板が有する突片を上板上面で摺接させて取出口側に移動させ、その突片を上板上面に突き当てて蓋板の起立状態を保つという手法を採ることなく、必要時にその蓋板の起立状態が維持できるようにすることを課題とし、粒菓子などを取り出す時に蓋板が邪魔になることなく取り扱いが容易な紙箱を得ることを目的とするものである。 However, in the above-described conventional paper box, since the tip of the projecting piece is in sliding contact with the upper surface of the upper plate when the lid plate body is rotated, the lid plate can be rotated with a moderate force and the lid plate. It is very difficult to obtain a paper box that can stably stand up as necessary because conditions such as paper thickness, paper hardness, and slipperiness of the upper surface of the upper plate must be taken into consideration.
Therefore, at present, the length of the projecting piece is increased so that the tilted state can be reliably maintained at the initial opening of the cover plate at the expense of a certain degree of rotational operability of the cover plate. If the lid plate is rotated repeatedly, the tip of the protruding piece will be crushed early, or the protruding piece will be bent, and the cover plate will not be kept upright, but will be put on the take-out side and the cover plate will be used to remove the contents. There was a problem of getting in the way.
Therefore, in view of the above circumstances, the present invention slidably contacts the protruding piece of the cover plate on the upper surface of the upper plate and moves it to the outlet side, and keeps the protruding plate in contact with the upper surface of the upper plate to keep the cover plate standing. The objective is to obtain a paper box that is easy to handle without taking the cover plate out of the way when taking out confectionery, etc. To do.

本発明は上記課題を考慮してなされたもので、菓子等の内容物の包装用の紙箱であって、上板と側板と底板からなる箱胴部の前記上板に重ね合わされる蓋板を備え、前記上板には、切り取り線で区画形成された閉鎖板で覆われてこの閉鎖板の引き起こしによる前記切り取り線の破断により開放可能で閉鎖板形状に対応する形状の取出口が設けられていて、前記蓋板は、蓋板支持部とこの蓋板支持部に折り罫を介して連接されて前記折り罫を中心に回動可能な蓋板本体とからなり、前記蓋板の蓋板支持部が閉鎖板を除く前記上板に貼り付けられているとともに、蓋板本体が前記閉鎖板に貼り付けられていて、蓋板本体を上板から引き起こす折り罫を中心にした回動で前記切り取り線が破断し前記閉鎖板が引き起こされて前記取出口が開く紙箱において、前記折り罫は、閉鎖板上であってこの閉鎖板を区画形成する前記切り取り線と交差する位置関係にして配置されて、前記閉鎖板は、前記折り罫との対応部位を境にして引き上げ部と降り部とからなり、前記引き上げ部の周縁の切り取り線の折り罫近傍位置に、該切り取り線を閉鎖板中心側に向けて凸にした鉤状線部を設けて、この鉤状線部を境にして閉鎖板に鉤状線部の形状に対応した切り欠き部が形成されているとともに、取出口の周辺に連続して鉤状線部の形状に対応した凸部が形成され、蓋板本体を引き起こす開き方向の回動に伴なった前記閉鎖板の前記折り罫を中心とした回転によって、取出口の前記凸部と閉鎖板の前記切り欠き部とが分離し、折り罫を中心にして閉鎖板の前記降り部が、取出口における引き上げ部対応領域側に向けて回動して、前記降り部が取出口の前記凸部の側縁に対して摺接移動し、折り罫部分の折り戻りにより取出口の降り部対応領域側に向けて回動する降り部と前記凸部との係止により、閉鎖板を伴なった蓋板本体の起立状態が維持されるように構成されていることを特徴とする紙箱を提供して、上記課題を解消するものである。 The present invention has been made in consideration of the above problems, and is a paper box for packaging contents such as confectionery, and a cover plate that is overlaid on the upper plate of the box body portion composed of an upper plate, a side plate, and a bottom plate. The upper plate is provided with an outlet having a shape corresponding to the shape of the closing plate, which is covered with a closing plate defined by a cutting line and can be opened by the breaking of the cutting line caused by the closing plate. The lid plate includes a lid plate support portion and a lid plate body connected to the lid plate support portion via a crease and rotatable about the crease, and the lid plate support of the lid plate The portion is attached to the upper plate excluding the closing plate, and the lid plate main body is attached to the closing plate, and the cutting is performed by turning around the crease that causes the lid plate main body from the upper plate. In the paper box where the wire breaks and the closing plate is raised to open the outlet The folding ruler is disposed on the closing plate in a positional relationship intersecting with the cut line that defines the closing plate, and the closing plate is located at a position corresponding to the folding rule. A hook-like line portion, which is composed of a lifting portion and a descending portion, is provided in the vicinity of the folding line of the cut-out line on the periphery of the lifting portion, and the cut-out line is convex toward the closing plate center side. A notch corresponding to the shape of the hook-shaped line part is formed on the closing plate with the boundary as a boundary, and a convex part corresponding to the shape of the hook-shaped line part is formed continuously around the outlet, The rotation of the closing plate about the folding ruled with the rotation of the opening direction causing the lid plate main body separates the convex portion of the outlet and the notch of the closing plate, and the folded ruled The lower part of the closing plate at the center is the area corresponding to the lifting part at the outlet. Rotating towards the side, the descending part moves in sliding contact with the side edge of the convex part of the outlet, and turns toward the descending part corresponding region side of the outlet by folding back of the crease part The above-mentioned problem is solved by providing a paper box that is configured so that the standing state of the lid plate body with the closing plate is maintained by the engagement of the descending portion and the convex portion. To do.

そして、本発明において、上記蓋板本体の蓋板支持部側の辺から蓋板支持部側に突出した突片が折り罫に連続した切り込みにより切り込み形成されて、前記突片が、蓋板本体の上記開き方向の回動に伴なって取出口の降り部対応領域の内縁に摺接して箱内に向けて回り込み可能に設けられていて、前記蓋板本体の開き方向の回動による蓋板本体の開き時に、前記突片の側辺と取出口の降り部対応領域の内縁とが当接し合うものとすることが良好である。 In the present invention, a protruding piece protruding from the side of the lid plate body on the lid plate support portion side to the lid plate support portion side is cut and formed by a cut continuous with the crease, and the projection piece is formed on the lid plate body. The lid plate is provided so as to be able to slidably come into contact with the inner edge of the area corresponding to the descending portion of the outlet as the opening direction of the door is rotated, and to rotate in the opening direction of the lid plate body. When the main body is opened, it is preferable that the side edge of the protruding piece and the inner edge of the exit corresponding area of the outlet are in contact with each other.

また、本発明において、上記突片は、上記閉鎖板の降り部に重なっていて、上記蓋板本体の開き方向の回動に伴なった取出口の降り部対応領域から引き上げ部対応領域側への回動により、前記閉鎖板の降り部を取出口の引き上げ部対応領域側に向けて押圧するものであるとすることが良好である。 In the present invention, the protruding piece overlaps the descending portion of the closing plate, from the descending portion corresponding region of the take-out port accompanying the rotation of the lid plate body in the opening direction to the lifting portion corresponding region side. It is preferable that the descending part of the closing plate is pressed toward the lifted part corresponding region side of the outlet by the rotation of.

また、本発明において、上記突片は、閉鎖板の降り部の両端部に対応して設けられているものとすることが良好である。 In the present invention, it is preferable that the protruding pieces are provided corresponding to both end portions of the descending portion of the closing plate.

（請求項１の発明の効果）
請求項１の発明により、蓋板本体を引き上げる開き方向の回動で閉鎖板の降り部が、取出口の引き上げ部対応領域側に向けて箱内部を回り込むように回動し、降り部が取出口の凸部の側縁に対して摺接移動し、折り罫部分の折り戻りにより取出口の降り部対応領域側に向けて回動する降り部と前記凸部とが係止して、閉鎖板を伴なった蓋板本体の起立状態が維持されるようにしている。
即ち、前記取出口の側辺の凸部が、閉鎖板の折り罫の位置を中心とした回転により取出口の引き上げ部対応領域に移動する降り部に対してその降り部の側辺が係脱可能に係止する位置となっていて、凸部との係止位置を通過移動した降り部が、蓋板本体の折り罫部分の復元力による蓋板本体の閉じ方向の回動により凸部とで係脱可能に係止するものであることから、蓋板本体を引き上げて折り罫部分の折り戻りで降り部を凸部に係止させるという簡単な操作で蓋板本体の起立状態が維持できる。そして、前記降り部が回動するときに凸部と干渉する箇所は、その凸部の極めて面積の小さい側縁だけであるため、降り部に曲がりや潰れが生じ難くなる。さらに凸部自体は、前記折り戻りで戻る降り部に係止さえすればよいものであるため、特に大きくする必要はなく、凸部を必要最小限の大きさのものとすることで、この点からも凸部と摺接するときの降り部の曲がりや潰れを抑えることができる。 (Effect of the invention of claim 1)
According to the first aspect of the present invention, the descending part of the closing plate is rotated so as to turn around the inside of the box toward the lifting part corresponding region side of the outlet by the pivoting in the opening direction for pulling up the lid plate body, and the descending part is removed. The sliding part moves in sliding contact with the side edge of the convex part of the exit, and the convex part is locked with the descending part that rotates toward the descending part corresponding area side of the outlet by the folding back of the crease part. The standing state of the lid plate body with the plate is maintained.
That is, the convex part on the side of the outlet is engaged with the descending part that moves to the lifting part corresponding region of the outlet by rotation about the position of the folding plate of the closing plate. The descending part that has been moved to the position where it can be locked and has passed through the locking position with the convex part is moved away from the convex part by the rotation of the lid plate body in the closing direction by the restoring force of the crease part of the lid plate body. The lid plate body can be maintained in an upright state by a simple operation of pulling up the lid plate body and locking the descending portion to the convex portion by folding back the crease part. . And since the part which interferes with a convex part when the said descending part rotates is only a side edge with the very small area of the convex part, it becomes difficult to produce a bending and a crush in a descending part. Further, since the convex portion itself has only to be locked to the descending portion that returns by the folding, it is not necessary to make the convex portion particularly large. Further, it is possible to suppress bending and crushing of the descending portion when it comes into sliding contact with the convex portion.

本発明ではさらにつぎの効果がある。例えば、菓子箱において、油脂分を含む粒菓子が紙箱に収容される場合もあり、箱内部の内底面や内側面にグラシン紙を配して油脂分が紙箱の包材に移って箱表面側にに染み出るのを防止している。そして、箱内部において収容物にグラシン紙を被せて内天面側にも油脂分が移り込むのを防止することが行なわれている。しかし、紙箱の上板側にグラシン紙が位置すると、その上板にある取出口から収容物を取り出すときにグラシン紙などが邪魔になり、一方、グラシン紙を用いないときには開かれている取出口を覆う蓋板に収容物の油脂分が移り込み易くなる。
また、菓子箱において、箱内面側となる面に耐油性の樹脂からなるコーティングが施された包材を用いて製函し、箱内面に位置したコーティング層により収納物からの油分止めるようにした紙箱もある。しかしながら、箱本体の上板に切り取りミシン目を入れ、その切り取りミシン目の破断によって蓋が開いて取出口が得られるようにした構造の紙箱や、予め開口されている取出口をその上方から蓋板で覆うようにし、蓋板の開きによって取出口が表れるようにした構造の紙箱では、切り取りミシン目におけるカット端面や取出口の内周端面は前記コーティング層が切れた状態となっていてその端面が箱内方に露出した状態となっている。そのため、端面露出部分に上記油脂分が染み込んで、切り取りミシン目の位置から箱外表面に油染みが表れたり、取出口の周囲に油染みが広く広がる可能性がある。 The present invention further has the following effects. For example, in a confectionery box, grain confectionery containing oil and fat may be stored in a paper box, and glassine paper is placed on the inner bottom surface and inner surface of the box, and the oil and fat moves to the packaging material of the paper box and the box surface side It prevents it from oozing out. In addition, it is performed that glassine paper is placed on the contents inside the box to prevent the oil and fat from moving to the inner top side. However, if glassine paper is positioned on the upper plate side of the paper box, the glassine paper will get in the way when removing the contents from the outlet on the upper plate, while the outlet is open when the glassine paper is not used. It becomes easy for the fats and oils in the contents to be transferred to the cover plate covering the.
In addition, in the confectionery box, the box was made using a packaging material coated with an oil-resistant resin on the inner surface of the box, and the coating layer located on the inner surface of the box stopped oil from the stored items. There is also a paper box. However, a paper box having a structure in which a cut perforation is formed in the upper plate of the box body and the lid is opened by breaking the cut perforation to obtain an outlet, or a previously opened outlet is covered from above. In a paper box with a structure in which the outlet is revealed by opening the cover plate, the cut end surface of the cut perforation and the inner peripheral end surface of the outlet are in a state where the coating layer is cut, Is exposed inside the box. Therefore, there is a possibility that the above-mentioned oil and fat may permeate into the exposed end surface, and the oil stain may appear on the outer surface of the box from the position of the cut perforation, or the oil stain may spread widely around the outlet.

この点に対して、本発明によれば、紙箱の天面部分が、閉鎖板で取出口を閉鎖している上板と蓋板とが重なった二重の構造となっている。そのため、仮に収容物の油脂分が直接上板に移り込んだとしても、上板の上の蓋板までには油脂分の移り込みが進まず、紙箱の外表面に油脂が染み出るのを防止し、上板について切り取り線部分での耐油性樹脂によるコーティング層の切れによる不具合は生じない。また、油脂分の移り込みを抑える別シートを収容物に被せ付ける必要がなくなり、取出口から収容物を取り出すときに、その収容物に被せた別シートが邪魔になるということが無くなる。 On the other hand, according to the present invention, the top surface portion of the paper box has a double structure in which the upper plate and the cover plate, which are closed with the closing plate, are overlapped. For this reason, even if the fats and oils in the contents are transferred directly to the upper plate, the fats and oils do not move up to the cover plate on the upper plate, preventing oil and fat from seeping out on the outer surface of the paper box. However, there is no problem with the upper plate due to the cutting of the coating layer with the oil-resistant resin at the cut line portion. In addition, it is not necessary to cover the container with another sheet for suppressing the transfer of the oil and fat, and when the container is taken out from the take-out port, the other sheet placed on the container is not obstructed.

（請求項２の発明の効果）
また、請求項２の発明によれば、蓋板本体に設けた突片が蓋板本体の起立状態のときに降り部対応領域の内縁に当接し合うようにしているので、折り罫部分の折り戻りによる蓋板本体の倒れを抑える上でその抑えを補助するようになり、蓋板本体の起立状態をより一層安定させることができる。
そして、降り部の凸部に対する係止とこの突片の降り部対応領域の内縁に対する当接とで蓋板本体の起立状態を維持するため、前記凸部の降り部に対する係止度合いをそれ程高める必要はなく、凸部自体の突出長さをより短かいものとすることができる。 (Effect of the invention of claim 2)
According to the second aspect of the present invention, since the protruding piece provided on the lid plate main body comes into contact with the inner edge of the descending portion corresponding area when the lid plate main body is in the standing state, In order to suppress the fall of the lid plate body due to the return, the restraint is assisted, and the standing state of the lid plate body can be further stabilized.
And in order to maintain the standing state of the cover plate body by the locking of the descending portion with respect to the convex portion and the contact with the inner edge of the descending portion corresponding region of the protruding piece, the degree of locking of the convex portion with respect to the descending portion is increased so much. There is no need, and the protrusion length of the protrusion itself can be made shorter.

（請求項３の発明の効果）
また、請求項３の発明により、蓋板本体を開き方向に回動するときに、突片が上記降り部に当てがわれてこの降り部を押圧するため、降り部が上記凸部の側縁に摺接する際に、この凸部の位置を簡単にして確実に通過するようになる。 (Effect of the invention of claim 3)
According to the invention of claim 3, when the lid plate body is rotated in the opening direction, the projecting piece is applied to the descending portion and presses the descending portion, so that the descending portion is a side edge of the convex portion. When slidably touching, the position of the convex portion is simplified and reliably passed.

（請求項４の発明の効果）
また、請求項４の発明により、降り部の両端部を突片の重ね合わせで補強でき、上記凸部との摺接による降り部の曲がりや潰れをより一層防止できる。 (Effect of the invention of claim 4)
According to the invention of claim 4, both ends of the descending portion can be reinforced by overlapping the protruding pieces, and bending and collapse of the descending portion due to sliding contact with the convex portion can be further prevented.

Reference numeral 6 represents a margin for pasting the body.

（蓋板）
さらにこの紙箱１では一方の側板３の一部分に蓋板７が連接されて上板２の上面に重ね合わされている。前記蓋板７は、上板２に貼り合わされている蓋板支持部８と、前記蓋板支持部８に折り罫９を介して連接された蓋板本体１０とからなり、前記蓋板支持部８のみが一方の側板３に連接されていて、後述するように蓋板本体１０が折り罫９を中心にして回動できるようにしている。
さらに蓋板本体１０の蓋板支持部８とは反対側の辺には、箱本体の一方の端部（箱胴部の一方の端部）に重ね合わせた貼着片１１が連接されていて、貼着片１１の下辺中央から蓋板本体連接側の辺（上辺）の両端に亘る対の切り取りミシン目で区画された部分を摘み部１２とし、この摘み部１２が上記蓋板本体１０に連接されているとともに、摘み部１２の切り取りミシン目を介して両側に位置する部分が箱本体の一方の端部に貼着されている。
即ち、切り取りミシン目を切断するように貼着片１１から摘み部１２を起こすことで蓋板本体１０のみに連接した摘み部１２となり、この摘み部１２を持ちながら蓋板本体１０を引き上げたり倒したりできる。 (Cover plate)
Further, in this paper box 1, a cover plate 7 is connected to a part of one side plate 3 and is superimposed on the upper surface of the upper plate 2. The lid plate 7 includes a lid plate support portion 8 bonded to the upper plate 2, and a lid plate body 10 connected to the lid plate support portion 8 via a crease 9, and the lid plate support portion Only 8 is connected to one side plate 3 so that the lid plate main body 10 can rotate around the folding ruled line 9 as will be described later.
Further, a sticking piece 11 superimposed on one end of the box main body (one end of the box body) is connected to the side of the lid main body 10 opposite to the lid support portion 8. A portion defined by a pair of cut perforations extending from the center of the lower side of the sticking piece 11 to both ends of the side (upper side) on the lid plate body connecting side is defined as a knob portion 12, and the knob portion 12 is formed on the lid plate body 10. While being connected, the part located in both sides via the cut perforation of the knob | pick part 12 is affixed on the one edge part of a box main body.
That is, by raising the knob portion 12 from the sticking piece 11 so as to cut the cut perforation, the knob portion 12 is connected to only the lid plate body 10, and the lid plate body 10 is pulled up or down while holding the knob portion 12. You can.

（蓋板の突片）
また、この蓋板７における蓋板支持部８と蓋板本体１０との間に位置する上記折り罫９は図示するように不連続であり、箱胴部の長手方向と直交する方向にして蓋板７の側辺側（側板側）と中央側との三ヶ所に位置している。
この折り罫９を中心として後述の回動をする前記蓋板本体１０には、蓋板支持部８側の辺から蓋板支持部８側に向けて突出した突片１３が連続している。この突片１３は前記折り罫９の不連続部分に位置していてその折り罫９に連続した切り込みで切り込み形成されいる。前述のようにこれら二つの突片１３は蓋板本体１０に連続し、かつ折り罫に沿った方向に交差する方向にして蓋板支持部８側に向けて突出しているため、この二つの突片１３が、蓋板本体１０の前記折り罫９を中心とした引き起こす方向での回動（蓋板本体の開き方向の回動）を行なえば、箱本体の内方側に向けて回り込むようにした回動をするようになる。
勿論、蓋板本体１０が上板２側に倒れ込む方向の回動をして倒れれば、上記二つの突片１３は蓋板支持部７と面一になる。 (Clip of cover plate)
Further, the crease 9 located between the lid plate support portion 8 and the lid plate body 10 in the lid plate 7 is discontinuous as shown in the figure, and the lid is formed in a direction perpendicular to the longitudinal direction of the box body portion. It is located at three locations on the side of the plate 7 (side plate side) and the center side.
A projecting piece 13 protruding from the side on the lid plate support portion 8 side toward the lid plate support portion 8 is continuous with the lid plate main body 10 that rotates as described below about the folding ruled line 9. The projecting piece 13 is located at a discontinuous portion of the crease 9 and is formed by being cut into the crease 9 continuously. As described above, these two protrusions 13 are continuous with the cover plate body 10 and protrude toward the cover plate support portion 8 in a direction intersecting the direction of the crease. If the piece 13 rotates in the direction that causes the lid plate body 10 to be centered on the crease 9 (rotation in the opening direction of the lid plate body), it turns around toward the inner side of the box body. Rotate.
Of course, if the lid plate body 10 is turned in the direction of falling to the upper plate 2 side and falls, the two projecting pieces 13 are flush with the lid plate support portion 7.

（上板）
箱胴部における上記上板２には、切り取り線１４で略矩形に区画形成された閉鎖板１５を備えていて、この閉鎖板１５の形状に対応した形状にした取出口１６が前記閉鎖板１５で覆われている。即ち、切り取り線１４を破断して前記閉鎖板１５を上板２から、例えば完全に取り外すようにすれば、その閉鎖板１５の形状に対応した開口形状の取出口が得られるようにしているものである。
このように上記上板２は、切り取り線１４で区画形成された閉鎖板１５で閉じられている取出口１６を有していて、上板２の上面側に重ねられた上記蓋板７の蓋板本体１０を引き上げることで、この蓋板本体１０に伴なって前記閉鎖板１５が引き起こされるようにしている。閉鎖板１５が引き起こされるようにするために、まず、突片１３も含めて蓋板支持部８の折り罫９側の近傍領域を上板２に非貼着にし、それ以外の蓋板支持部８を上述したように上板２に貼り合わされている。また、蓋板本体１０は閉鎖板１５のみに貼り合わされていて、上記摘み部１２を貼着片１１から起こし、さらにこの摘み部１２を持って蓋板本体１０を折り罫９を中心にして回動するように引き上げることで、上記切り取り線１４が破断して、閉鎖板１５も折り罫９を中心として回転して引き起こされ、蓋板本体１０が開いて取出口１６が開放される状態となる。 (Upper plate)
The upper plate 2 in the box body portion is provided with a closing plate 15 partitioned into a substantially rectangular shape by a cut line 14, and an outlet 16 having a shape corresponding to the shape of the closing plate 15 is provided in the closing plate 15. Covered with. That is, if the cut line 14 is broken and the closing plate 15 is completely removed from the upper plate 2, for example, an opening having an opening shape corresponding to the shape of the closing plate 15 is obtained. It is.
As described above, the upper plate 2 has the outlet 16 closed by the closing plate 15 defined by the cut line 14, and the lid of the lid plate 7 stacked on the upper surface side of the upper plate 2. By pulling up the plate body 10, the closing plate 15 is caused to accompany the lid plate body 10. In order to cause the closing plate 15 to be raised, first, the region near the folding line 9 side of the lid plate support portion 8 including the projecting piece 13 is not adhered to the upper plate 2, and the other lid plate support portions 8 is bonded to the upper plate 2 as described above. Further, the lid plate body 10 is bonded only to the closing plate 15, and the knob portion 12 is raised from the sticking piece 11, and the lid plate body 10 is rotated around the crease 9 with the knob portion 12. By pulling up so as to move, the cut line 14 is broken, the closing plate 15 is also rotated around the folding line 9, and the lid plate main body 10 is opened and the outlet 16 is opened. .

（閉鎖板）
蓋板本体１０の回動に伴なうようにした閉鎖板１５にあっては、蓋板本体１０の引き起こしによる開き方向の回動に際して、この閉鎖板１５の大部分が箱本体の上方に向けて引き起こされるように折り罫９を中心として回転するとともに、残りの一部分が箱本体の内方に向けて回り込むように折り罫９を中心として回転するものとされている。
この折り罫９を中心として閉鎖板１５を回転できるようにするために、閉鎖板１５と折り罫９との位置関係を以下のようにしている。即ち、前記折り罫９は、閉鎖板１５上であって切り取り線１４の箱長さ方向に沿った二線部１４ａと直角に交差する位置関係にして配置されている。そして、前記閉鎖板１５は、前記折り罫９が通る位置に対応した折り罫対応部位ａを境にして蓋板本体１０が重なる引き上げ部１７と蓋板支持部８が重なる降り部１８とに区分される。取出口１６も、前記引き上げ部１７が位置する引き上げ部対応領域１９と、前記降り部１８が位置する降り部対応領域２０とに区分されることになる。
閉鎖板１５における引き上げ部１７は、折り罫対応部位ａ側に蓋板本体１０に対して非接着となる非接着部分２１を有し、この非接着部分２１以外の部分が上述したように蓋板本体１０に接着されている。そのため、前記蓋板本体１０を引き上げて折り罫９を中心にして開き方向に回動すれば、閉鎖板１５の引き上げ部１７の周囲の切り取り線１４が破断してその引き上げ部１７が蓋板本体１０に伴なって引き起こされ、折り罫９を中心として開き方向に回転して取出口１６の引き上げ部対応領域１９が開放される。また、同時に閉鎖板１５の降り部１８の周囲の切り取り線１４が破断し、その降り部１８が、折り罫９を中心にして箱本体の内方側に向けて回り込むように回転する。そして、降り部１８が位置していた取出口１６での降り部対応領域２０が開放された状態となる。
なお、蓋板本体１０を逆方向（閉じ方向）に回動すれば、引き上げ部１７が取出口１６の引き上げ部対応領域１９に位置に戻り、また、降り部１８が取出口１６の降り部対応領域２０の位置に戻って、未開封時と同様に閉鎖板１５によって取出口１６が覆われるようになる。 (Closing plate)
In the closing plate 15 that is accompanied by the rotation of the lid plate body 10, most of the closing plate 15 is directed upward of the box body when the lid plate body 10 is turned in the opening direction. The folding line 9 is rotated around the folding line 9 so as to be caused by the rotation, and the folding line 9 is rotated around the folding line 9 so that the remaining part wraps around the inside of the box body.
In order to be able to rotate the closing plate 15 around the folded rule 9, the positional relationship between the closing plate 15 and the folded rule 9 is as follows. In other words, the folding ruler 9 is arranged on the closing plate 15 in a positional relationship that intersects the two-wire portion 14a along the box length direction of the cut line 14 at a right angle. The closing plate 15 is divided into a lifting portion 17 where the lid plate body 10 overlaps and a descending portion 18 where the lid plate support portion 8 overlaps with a crease corresponding part a corresponding to the position where the crease 9 passes. Is done. The outlet 16 is also divided into a lifting portion corresponding region 19 where the lifting portion 17 is located and a descending portion corresponding region 20 where the descending portion 18 is located.
The lifting portion 17 in the closing plate 15 has a non-adhesive portion 21 that is non-adhered to the lid plate main body 10 on the crease-corresponding portion a side, and the portions other than the non-adhesive portion 21 are the cover plate as described above. Bonded to the main body 10. Therefore, if the lid plate body 10 is pulled up and rotated in the opening direction around the crease 9, the tear line 14 around the lifting portion 17 of the closing plate 15 is broken and the lifting portion 17 becomes the lid plate body. 10 and is rotated in the opening direction around the crease 9 to open the lifting portion corresponding area 19 of the outlet 16. At the same time, the cut line 14 around the descending portion 18 of the closing plate 15 is broken, and the descending portion 18 rotates around the folding ruler 9 toward the inward side of the box body. And the descending part corresponding | compatible area | region 20 in the taking-out port 16 in which the descending part 18 was located will be in the open state.
If the lid body 10 is rotated in the reverse direction (closing direction), the lifting portion 17 returns to the position corresponding to the lifting portion corresponding area 19 of the outlet 16, and the lowering portion 18 corresponds to the lowering portion of the outlet 16. Returning to the position of the region 20, the outlet 16 is covered with the closing plate 15 as in the case of unopened.

（切り取り線）
図３に示すように、閉鎖板１５を上板２中で区画している切り取り線１４の内、上記引き上げ部１７の周縁の切り取り線１４の折り罫対応部位ａの近傍位置に、該切り取り線１４を閉鎖板中心側に向けて凸にした鉤状線部２２が設けられている。
そして、上記鉤状線部２２を境にして閉鎖板１５の引き上げ部１７には、該引き上げ部１７の折り罫対応部位ａと直交する辺であって、降り部１８側に近接する位置に前記鉤状線部２２の形状に対応した切り欠き部２３が形成されているとともに、取出口１６の引き上げ部対応領域１９での周辺に連続して鉤状線部２２の形状に対応した凸部２４が形成され、この凸部２４は、引き上げ部対応領域１９の周辺において、折り罫対応部位ａと直交する箇所に近接した位置に形成されている。
切り取り線１４は、切れ目を不連続に並べて線状に配列してなるものであり、上記鉤状線部２２においては切れ目の並びが鉤状であればよいものである。例えば、この鉤状線部２２の位置で一つの切れ目を略レ字状に切り込んでもよい。また、略ヘ字状の切れ目の傾斜部分を閉鎖板中心側に向けて切り込むようにしたものであってもよく、この場合、未開封の時点において上記切り欠き部２３と凸部２４とは一部分において連続した状態となる。勿論、この連続部分は、切り取り線１４での切れ目と切れ目との間の連続部分であり、容易に切断される箇所である。 (Cut line)
As shown in FIG. 3, among the cut lines 14 that divide the closing plate 15 in the upper plate 2, the cut lines 14 are arranged at positions in the vicinity of the crease-corresponding portion a of the cut lines 14 at the periphery of the lifting portion 17. A hook-like line portion 22 is provided in which 14 is convex toward the center side of the closing plate.
Then, the lifting portion 17 of the closing plate 15 with the saddle-shaped line portion 22 as a boundary is a side perpendicular to the crease-corresponding portion a of the lifting portion 17 and is located at a position close to the descending portion 18 side. A cutout portion 23 corresponding to the shape of the hook-shaped line portion 22 is formed, and a convex portion 24 corresponding to the shape of the hook-shaped line portion 22 is continuously provided in the vicinity of the lifting portion corresponding area 19 of the outlet 16. The convex portion 24 is formed at a position close to a portion orthogonal to the crease-corresponding portion a around the raised portion corresponding region 19.
The cut lines 14 are formed by discontinuously arranging the cuts in a line, and the cut lines in the hook-like line portion 22 only need to be hooked. For example, one cut may be cut into a substantially letter shape at the position of the hook-shaped line portion 22. Further, the inclined portion of the substantially square-shaped cut may be cut toward the center of the closing plate, and in this case, the notch portion 23 and the convex portion 24 are partially formed at the time of unopening. In a continuous state. Of course, this continuous portion is a continuous portion between the cuts at the cut line 14 and is a portion that is easily cut.

（蓋板本体の引き上げ）
上述したように閉鎖板１５の引き上げ部１７の周辺となる切り取り線１４とに、その切り取り線１４に直交する折り罫対応部位ａに近傍となる位置にして鉤状線部２２が設けられて、取出口１６における引き上げ部対応領域１９の折り罫対応部位ａと直交する箇所に近接した位置にして、凸部２４が形成されているため、この凸部２４と閉鎖板１５の降り部１８とを係止させることで、以下のように閉鎖板１５を伴なった蓋板本体１０の起立状態を維持し、取出口１６の開放状態を維持できるようにしている。 (Pull up the lid body)
As described above, the hook-like line portion 22 is provided on the cut line 14 around the lifting portion 17 of the closing plate 15 at a position near the crease-corresponding portion a orthogonal to the cut line 14. Since the convex portion 24 is formed at a position close to a portion orthogonal to the crease corresponding portion a of the lifting portion corresponding region 19 in the outlet 16, the convex portion 24 and the descending portion 18 of the closing plate 15 are connected to each other. By locking, the standing state of the lid plate body 10 with the closing plate 15 is maintained as follows, and the open state of the outlet 16 can be maintained.

蓋板本体１０を開いた状態に維持させるためには、上記摘み部１２を持って蓋板本体１０を折り罫９を中心として開き方向に回動させる。この回動に伴なう閉鎖板１５が折り罫９の位置を中心として回転して、閉鎖板１５周囲の切り取り線１４が破断し、閉鎖板１５の上記切り欠き部２３と取出口１６の上記凸部２４とが分離する。また、閉鎖板１５の降り部１８は取出口１６の降り部対応領域２０から離れて箱本体の内部に向けて回り込むように折り罫の位置を中心にして回転する。
さらに蓋板本体１０を蓋板支持部８側に回動させることで、折り罫９の位置を中心にして降り部１８が箱内部に回り込み、取出口１６における引き上げ部対応領域１９側に向けて回動する。前記降り部１８が引き上げ部対応領域１９側に向けて回動する途中で、降り部１８の折り罫対応部位ａの長手方向で対向する側辺２５が凸部２４に接触する。
前記凸部２４の降り部対応領域２０側に臨む側縁は取出口１６の中心側に向けて傾斜していて、降り部１８の側辺２５が前記凸部２４の側縁に対して摺接移動可能に設けられている。そのため降り部１８の側辺２５が凸部２４に接触しても止まることなく、凸部２４に摺接しながら移動してこの凸部２４を乗り越えるようにして取出口１６の引き上げ部対応領域１９側に移動する。このように取出口１６の側辺の凸部２４は、閉鎖板１５の折り罫９の位置を中心とした回転により取出口１６の引き上げ部対応領域１９に移動する前記降り部１８に対してその降り部１８の側辺２５が係脱可能に係止する位置としている。さらに、前記閉鎖板１５の回転に伴なって引き上げ部対応領域１９に移動する降り部１８が、凸部２４との係止位置に達し、その係止位置で摺接を行なってから先に移動する。 In order to maintain the lid plate main body 10 in the open state, the lid plate main body 10 is rotated in the opening direction around the crease 9 with the knob 12. With this rotation, the closing plate 15 rotates around the position of the crease 9, the cut line 14 around the closing plate 15 is broken, and the notch 23 of the closing plate 15 and the above-mentioned outlet 16 are The convex part 24 isolate | separates. Further, the descending portion 18 of the closing plate 15 rotates around the position of the crease so as to move away from the descending portion corresponding area 20 of the outlet 16 and wrap around toward the inside of the box body.
Further, by rotating the lid plate body 10 toward the lid plate support portion 8, the descending portion 18 goes around the box centering on the position of the crease 9 and toward the lifting portion corresponding region 19 side at the outlet 16. Rotate. While the descending portion 18 is rotated toward the lifting portion corresponding region 19 side, the side edges 25 facing in the longitudinal direction of the crease corresponding portion a of the descending portion 18 come into contact with the convex portion 24.
The side edge of the convex portion 24 facing the descending portion corresponding region 20 side is inclined toward the center side of the outlet 16, and the side 25 of the descending portion 18 is in sliding contact with the side edge of the convex portion 24. It is provided to be movable. Therefore, even if the side 25 of the descending portion 18 comes into contact with the convex portion 24, it moves while sliding on the convex portion 24 so as to get over the convex portion 24, and on the side of the lifting portion corresponding region 19 of the outlet 16. Move to. In this way, the convex portion 24 on the side of the outlet 16 is in relation to the descending portion 18 that moves to the lifting portion corresponding area 19 of the outlet 16 by rotation about the position of the crease 9 of the closing plate 15. It is set as the position which the side 25 of the descending part 18 latches so that engagement / disengagement is possible. Further, the descending portion 18 that moves to the lifting portion corresponding area 19 with the rotation of the closing plate 15 reaches the locking position with the convex portion 24 and moves forward after making sliding contact at the locking position. To do.

そして、蓋板本体１０を回動させている手を離すことで、折り罫部分の折り戻り（蓋板７の折り罫部分の復元力による伸展）により蓋板本体１０は閉じ方向に自然に回動し、この蓋板本体１０に伴なっている閉鎖板１５は折り罫９の位置を中心にして取出口１６を閉じる方向に回転する。このとき、閉鎖板１５の降り部１８は降り部対応領域２０に戻る方向に回転し始めるが、図５に示すように降り部１８の上記側辺２５と上記凸部２４とが係止して、降り部１８の降り部対応領域２０に戻る方向に回転移動が止められる。即ち、凸部２４との係止位置を経た降り部１８は、蓋板本体１０の折り罫部分の復元力による蓋板本体１０の閉じ方向の回動により凸部２４とで係脱可能に係止するものであることから、戻りに際して凸部２４との係止位置で係止する。よって、蓋板本体１０が起立状態で止まり、その起立状態が維持されるようになる。閉鎖板１５の引き上げ部１７も蓋板本体１０に貼り合わされているため、取出口１６での引き上げ部対応領域１９は開放された状態が維持される。
蓋板本体１０を開き方向に回動させる際、その蓋板本体１０を蓋板支持部８側に深く倒し込まなくても、降り部１８が凸部２４の位置を通過した時点の軽い振動が蓋板本体１０を持つ指先に伝わって、蓋板本体１０を開き方向に回動させる操作を止めるタイミングが判り、蓋板本体１０を起立状態にすることが容易に行なえるものとなっている。 Then, by releasing the hand that rotates the lid plate body 10, the lid plate body 10 naturally rotates in the closing direction by folding back of the crease portion (extension by the restoring force of the crease portion of the lid plate 7). The closing plate 15 associated with the lid plate main body 10 rotates in the direction of closing the outlet 16 around the position of the crease 9. At this time, the descending portion 18 of the closing plate 15 begins to rotate in a direction to return to the descending portion corresponding area 20, but the side 25 of the descending portion 18 and the convex portion 24 are locked as shown in FIG. The rotational movement is stopped in the direction in which the descending portion 18 returns to the descending portion corresponding area 20. That is, the descending portion 18 that has passed through the locking position with the convex portion 24 is detachably engaged with the convex portion 24 by the rotation of the lid plate body 10 in the closing direction by the restoring force of the crease portion of the lid plate main body 10. Since it stops, it is locked at the locking position with the convex portion 24 when returning. Therefore, the lid plate body 10 stops in the standing state, and the standing state is maintained. Since the lifting portion 17 of the closing plate 15 is also bonded to the lid body 10, the lifting portion corresponding area 19 at the outlet 16 is kept open.
When the lid plate main body 10 is rotated in the opening direction, even when the lid plate main body 10 is not tilted deeply into the lid plate support portion 8 side, the light vibration when the descending portion 18 passes the position of the convex portion 24 is generated. The timing of stopping the operation of rotating the lid plate body 10 in the opening direction by being transmitted to the fingertip having the lid plate body 10 is known, and the lid plate body 10 can be easily raised.

蓋板本体１０を閉じる際には、単にこの蓋板本体１０を取出口１６側に倒すように閉じる方向に回動させればよく、二つの凸部２４に側辺２５を係脱可能に係止させている降り部１８は降り部対応領域２０側に向けた回動をすることにより、降り部１８の両側辺２５側の部分が僅かに撓むなどにし、これによって凸部２４との係止が解かれて降り部１８が降り部対応領域２０に戻り、また、引き上げ部１７が引き上げ部体領域１９に戻って、取出口１６に閉鎖板１５が位置して閉じられ、蓋板本体１０によって取出口１６が覆われるようになる。
なお、凸部２４は降り部１８が係脱可能に係止するものであり、この凸部２４それぞれの突出長さ（折り罫対応部位ａ方向に沿った突出長さ）は、蓋板本体１０を閉じ方向に回動操作するときに抵抗を生じさせない突出長さに設定されている。 When closing the lid plate main body 10, the lid plate main body 10 may be simply pivoted in the closing direction so that the lid plate main body 10 is tilted toward the outlet 16, and the side 25 can be engaged with and disengaged from the two convex portions 24. The descending portion 18 that is stopped is rotated toward the descending portion corresponding region 20 side, so that the portions on the both sides 25 side of the descending portion 18 are slightly bent, thereby engaging with the convex portion 24. The stop is released and the descending part 18 returns to the descending part corresponding area 20, and the lifting part 17 returns to the lifting part body area 19, and the closing plate 15 is positioned at the outlet 16 and closed. As a result, the outlet 16 is covered.
The protruding portion 24 is engaged with the descending portion 18 so that the protruding portion 18 is detachable. The protruding length of each protruding portion 24 (the protruding length along the crease-corresponding portion a) is the lid plate body 10. The protrusion length is set so as not to generate resistance when the is rotated in the closing direction.

上記取出口１６の周縁に連続している上記凸部２４は、上述したように折り罫対応部位ａに近接し、その折り罫対応部位ａの長手方向で対向する配置にして設けられている。そして二つの凸部２４それぞれの突出長さが異なっていて（図３参照）。上記降り部１８が凸部２４の側縁に摺接しながら移動する際、突出長さの短かい方の凸部２４に摺接移動している側辺が先にその凸部２４の位置を通過し、その後、突出長さの長い方の凸部２４に摺接移動している側辺がその凸部２４の位置を通過するようにしていて、側辺２５それぞれの凸部位置の通過タイミングを僅かに異ならせることにより、降り部１８全体に折り罫対応部位ａ長手方向でのネジれやズレを生じさ、凸部２４との摺接によって生じる応力が局部に集中しないように分散させている。降り部１８のネジれやズレは蓋板本体１０の開き方向での回動操作時や閉じ方向の回動操作時にも生じるものであり、いずれの場合でも降り部１８に局部的な応力集中が生じないようにしているものである。なお、この二つの凸部２４の突出長さを変える必要は必ずしもない。 The convex part 24 continuing to the peripheral edge of the outlet 16 is provided so as to be close to the crease-corresponding part a and opposed to the crease-corresponding part a in the longitudinal direction. The projecting lengths of the two convex portions 24 are different (see FIG. 3). When the descending portion 18 moves while being in sliding contact with the side edge of the convex portion 24, the side that is slidingly moving to the convex portion 24 having the shorter protruding length first passes through the position of the convex portion 24. After that, the side that is slidably moving to the convex part 24 having the longer protruding length passes through the position of the convex part 24, and the passing timing of the convex part position of each side 25 is determined. By slightly differing, the entire descending part 18 is twisted or displaced in the longitudinal direction corresponding to the crease-corresponding part a, and the stress generated by the sliding contact with the convex part 24 is dispersed so as not to concentrate on the local part. . Twist and misalignment of the descending portion 18 occur even when the lid body 10 is rotated in the opening direction or when the lid plate body 10 is rotated in the closing direction. In any case, local stress concentration occurs in the descending portion 18. This is to prevent it from occurring. Note that it is not always necessary to change the protruding length of the two convex portions 24.

（非接着部分）
上述したように閉鎖板１５における引き上げ部１７の折り罫対応部位ａ側に蓋板本体１０に対して貼着していない非接着部分２１を有しており、そして、前記非接着部分２１に連続して閉鎖板１５の降り部１８も上述してきたように蓋板支持部８に対して非接着とされている。このように引き上げ部１７の降り部１８側が蓋板７に対して非接着とされて降り部１８に連続しているため、降り部１８の上記ネジれやズレ（折り罫対応部位長手方向でのズレ）を降り部１８だけで行なわせるものとはしておらず、引き上げ部１７の非接着部分２１となっている部分も含めてネジれやズレを行ない、降り部１８に応力が集中しないようにしている。 (Non-adhesive part)
As described above, the closing plate 15 has the non-adhesive portion 21 that is not attached to the lid plate main body 10 on the side of the folding line corresponding portion a of the lifting portion 17, and is continuous with the non-adhesive portion 21. The descending portion 18 of the closing plate 15 is also not bonded to the lid plate support portion 8 as described above. Thus, since the descending portion 18 side of the lifting portion 17 is not bonded to the lid plate 7 and is continuous with the descending portion 18, the twist and displacement of the descending portion 18 (in the longitudinal direction corresponding to the folding line) The misalignment is not performed only by the descending portion 18, and twisting and misalignment including the portion that is the non-adhesive portion 21 of the lifting portion 17 is performed so that stress is not concentrated on the descending portion 18. I have to.

（突片の当接）
蓋板本体１０の二つの突片１３は、閉鎖板１５の上記降り部１８の両端部に対応する位置であって、突片１３それぞれの外側辺（蓋板７の辺側）が降り部対応領域２０の内縁の位置に対応している。そして、上述したように蓋板本体１０が開き方向に回動するとき、突片１３それぞれは箱内部に入り込むようにして折り罫９の位置を中心に回動する。この箱内部に向けて回動するときには、図６に示されているように突片１３それぞれの外側縁が、降り部対応領域２０の内縁に摺接する。
さらに蓋板本体１０の開き方向の回動に伴なってこの突片１３それぞれも上記凸部２４に摺接しながらその凸部２４の位置に差し掛かり、上記降り部１８の側辺が凸部２４に係止して蓋板本体１０の起立状態が維持されるように蓋板本体１０が折り罫９の位置での折り戻りによって若干閉じ方向に回動すると、蓋板本体７の折り罫周りと閉鎖板１５の上記非接着部分２１との間がわずかに開き、突片１３それぞれが凸部２４の位置から降り部対応領域２０側に戻る回動をする。そして、降り部対応領域２０に位置した突片１３それぞれの外側辺は、降り部対応領域２０の内縁と当接し合うようになり、この突片１３の外側辺と降り部対応領域２０の内縁との当接によっても蓋板本体１０の閉じ方向の回動を抑え込み、凸部２４と降り部１８との係止による蓋板本体１０の起立状態の維持を補助するようにしている。
なお、蓋板本体１０の閉じ方向に回動させれば、この突片１３の外側辺と降り部対応領域２０の内縁との当接は簡単に解除されるものであり、閉じ方向の回動操作に支障を来たすことがないように設けられている。 (Projection contact)
The two projecting pieces 13 of the lid plate main body 10 are positions corresponding to both end portions of the descending portion 18 of the closing plate 15, and the outer sides (side sides of the lid plate 7) of the projecting pieces 13 correspond to the descending portions. This corresponds to the position of the inner edge of the region 20. As described above, when the lid plate main body 10 rotates in the opening direction, each of the projecting pieces 13 rotates around the position of the crease 9 so as to enter the inside of the box. When rotating toward the inside of the box, as shown in FIG. 6, the outer edge of each of the projecting pieces 13 comes into sliding contact with the inner edge of the descending portion corresponding region 20.
Further, as the lid body 10 rotates in the opening direction, each of the projecting pieces 13 also reaches the position of the projecting portion 24 while being in sliding contact with the projecting portion 24, and the side of the descending portion 18 faces the projecting portion 24. When the lid plate main body 10 is pivoted in the closing direction by folding back at the position of the crease 9 so that the lid plate main body 10 is maintained in an upright state, the lid plate main body 7 is closed around the crease and closed. The space between the plate 15 and the non-adhesive portion 21 is slightly opened, and each of the projecting pieces 13 rotates from the position of the convex portion 24 to the descending portion corresponding region 20 side. And the outer side of each protrusion 13 located in the descending part corresponding region 20 comes into contact with the inner edge of the descending part corresponding region 20, and the outer side of this protruding piece 13 and the inner edge of the descending part corresponding region 20 Also, the rotation of the lid plate body 10 in the closing direction is suppressed by the contact, and the maintenance of the standing state of the lid plate body 10 by the engagement between the convex portion 24 and the descending portion 18 is assisted.
If the lid plate body 10 is rotated in the closing direction, the contact between the outer side of the projecting piece 13 and the inner edge of the descending portion corresponding region 20 is easily released, and the closing plate is rotated in the closing direction. It is provided so as not to hinder the operation.

（突片による降り部の押し）
上述したように突片１３は上記降り部１８の両端部に対応して設けられていて、蓋板本体１０が閉じた状態であるときには前記降り部１８の両端部に重なっている。そのため、蓋板本体１０の開き方向の回動に伴なって突片１３それぞれが降り部対応領域２０から箱内部側に入り込むようにして引き上げ部対応領域１９側へ回動し、前記降り部１８の両端部が上記凸部２４に接触したときにこの降り部１８の両端部を引き上げ部対応領域１９側に向けて押圧する。これにより降り部１８は凸部２４に摺接しながらも停止することなくその凸部位置を簡単に通過するようになる。
なお、突片１３自体は上記降り部対応領域２０の内縁との当接しないように降り部１８の中心側に寄った位置にしてこの降り部１８の両端部を押圧する役割のみのものとしてもよい。また、突片１３自体も必ず必要とされるものではない。 (Pushing down part by protruding piece)
As described above, the projecting pieces 13 are provided corresponding to both end portions of the descending portion 18, and overlap the both end portions of the descending portion 18 when the cover plate body 10 is in a closed state. Therefore, as the lid body 10 is rotated in the opening direction, each of the projecting pieces 13 is rotated from the descending portion corresponding region 20 to the inside of the box to the lifting portion corresponding region 19 side, and the descending portion 18 is rotated. When both end portions of the contact portion come into contact with the convex portion 24, both end portions of the descending portion 18 are pressed toward the lifting portion corresponding region 19 side. As a result, the descending portion 18 can easily pass through the convex portion position without stopping while sliding on the convex portion 24.
Note that the protruding piece 13 itself has a role of pressing the both ends of the descending portion 18 at a position close to the center side of the descending portion 18 so as not to contact the inner edge of the descending portion corresponding area 20. Good. Further, the protruding piece 13 itself is not necessarily required.

（蓋板本体の閉じ維持）
蓋板本体１０は開き方向や閉じ方向に回動させることができ、開き方向に回動して上述のように閉鎖板１５の降り部１８と取出口１６の凸部２４との係止を行なうという簡単な操作で、蓋板本体の起立状態を維持でき、そして、蓋板本体１０を倒すことで前記係止が解かれて蓋板本体１０を閉じ位置へ戻すことができる。なお、蓋板本体１０の閉じをより確実にするために、例えば上記摘み部１２の一部分を箱本体の端部に設けたスリットにさし込むようにするなどの公知の手法が採用できる。 (Keep the lid body closed)
The lid plate main body 10 can be rotated in the opening direction and the closing direction, and is rotated in the opening direction to lock the descending portion 18 of the closing plate 15 and the convex portion 24 of the outlet 16 as described above. With this simple operation, the upright state of the lid plate body can be maintained, and the lid plate body 10 can be returned to the closed position by releasing the locking by tilting the lid plate body 10. In order to more reliably close the lid body 10, for example, a known method such as inserting a part of the knob 12 into a slit provided at the end of the box body can be employed.
