Description

この考案はケーキ等の収容物を収容携帯する折り畳み式包装箱において、特に側壁に形成された溝孔に対する係止板の固定構造に関する。   The present invention relates to a structure for fixing a locking plate to a slot formed in a side wall, particularly in a foldable packaging box that accommodates and carries items such as cakes.

従来の包装箱としては、底板、両側壁、前後壁よりなり、組立てた状態で把手の両側に形成した凹凸状のフック部に、側壁から立設した係止孔付きの係止板に挿通係止する事により蓋と把手を係止固定する包装箱において、後壁側端に起立状態で左右側壁と重なり合うフラップ片を折り曲げ可能に連設し、該フラップ片の上端に前記係止板を連設するとともに、左右側壁の溝孔に係止板を挿通して係止するものが公知である（例えば、特許文献１参照。）。
特開２００３−２２６３２５号公報（図２，３） As a conventional packaging box, it consists of a bottom plate, both side walls, and front and rear walls, and is inserted into a locking plate with a locking hole standing from the side wall on an uneven hook part formed on both sides of the handle in the assembled state. In the packaging box in which the lid and the handle are locked and fixed by being stopped, a flap piece that overlaps the left and right side walls in a standing state is connected to the rear wall side end in a foldable manner, and the locking plate is connected to the upper end of the flap piece. It is well known that the locking plate is inserted and locked into the groove holes on the left and right side walls (see, for example, Patent Document 1).
JP 2003-226325 A (FIGS. 2 and 3)

上記従来の包装箱は、左右側壁上部に穿設された溝孔に対してフラップ片の上端に折曲げ可能に連設された係止板を挿通して係止することが可能であるが、左右側壁の起立状態において係止板を溝孔に挿入した場合、たびたび係止板が溝孔から抜けてしまい包装箱の閉蓋及び箱組み作業に支障を来していた。   The conventional packaging box can be locked by inserting a locking plate continuously connected to the upper end of the flap piece in a groove formed in the upper part of the left and right side walls so that it can be bent. When the locking plate is inserted into the slot with the left and right side walls standing, the locking plate often comes out of the slot, which hinders the packaging box closing and box assembly operations.

また溝孔から係止板が抜けるために、左右側壁とフラップ片とを当接状態に保持することができず、前壁及び前フラップの開放状態においてケーキ等の内容物の出し入れをする際に、前端部が揺動状態であるフラップ片によってケーキ等の内容物を傷つけるという問題があった。
この考案はこれらの問題点を解決又は改善しようとするものである。 In addition, since the locking plate comes out of the slot, the left and right side walls and the flap piece cannot be held in contact with each other, and the contents such as cake are taken in and out in the opened state of the front wall and the front flap. There is a problem that the contents of the cake and the like are damaged by the flap piece whose front end is in a swinging state.
The present invention is intended to solve or improve these problems.

上記課題を解決するための本考案の包装箱は、第１に、多角形の底板２の直交方向に相対する２組の辺に左右の各一対の側壁３，４と前後壁６，７をそれぞれ折り曲げ起伏可能に連設し、上記前後壁６，７の上端に上部蓋を兼ねた前半部及び後半部の天板８を構成する前天板８ａと後天板８ｂを折り曲げ可能に連設し、該前後の天板８ａ，８ｂの先端に前後に重ね合わせて折り曲げ起立可能な把手９ａ，９ｂを各連設するとともに、各各側壁中央には、閉蓋時に前後に重ね合わせた起立状態の把手９ａ，９ｂの左右両端を挿通係止して、把手９ａ，９ｂを側壁３，４側に起立状態で係止固定する舌状の係止板１１を折り曲げ可能に連設し、把手９ａ，９ｂの両端に該把手９ａ，９ｂを係止板１１側に係止するフック部１２を形成すると共に、係止板１１に上記フック部１２を挿通可能な係止孔３０を形成し、少なくとも前壁６又は後壁７側端に起立状態で左右側壁３，４と重なり合うフラップ片１３を折り曲げ可能に連設し、該フラップ片１３の上端に前記係止板１１を突設するとともに、左右側壁３，４の上端より下方位置にはフラップ片１３を起立させた状態で、前記係止板１１を左右方向に挿通する前後方向の溝孔５を穿設してなる包装箱において、係止板１１の基端部に該係止板１１を溝孔５に挿通後内側に折曲げた際に係止板１１を起立方向に付勢する形状の折目１４ｂを形成してなることを特徴としている。   The packaging box of the present invention for solving the above-mentioned problem is as follows. First, a pair of left and right side walls 3 and 4 and front and rear walls 6 and 7 are provided on two sets of sides facing the orthogonal direction of the polygonal bottom plate 2. The front top plate 8a and the rear top plate 8b constituting the top plate 8 of the front half and the rear half that also serve as an upper lid are connected to the upper ends of the front and rear walls 6 and 7 so as to be bendable. The front and rear top plates 8a, 8b are respectively provided with handles 9a, 9b which can be folded and raised in the front-rear direction, and at the center of each side wall, the handles in the standing state which are overlapped in the front-rear direction when the lid is closed. The left and right ends of 9a and 9b are inserted and locked, and a tongue-shaped locking plate 11 for locking and fixing the grips 9a and 9b to the side walls 3 and 4 in an upright state is connected to the grips 9a and 9b. A hook portion 12 for locking the grips 9a, 9b to the locking plate 11 side at both ends of the A locking hole 30 through which the hook portion 12 can be inserted is formed in the stop plate 11, and at least at the front wall 6 or the rear wall 7 side end, the flap pieces 13 that overlap the left and right side walls 3, 4 in a standing state are arranged continuously. The locking plate 11 protrudes from the upper end of the flap piece 13 and the locking plate 11 is moved in the left-right direction with the flap piece 13 raised from the upper ends of the left and right side walls 3 and 4. In the packaging box formed by piercing the slot 5 in the front-rear direction, the locking plate is inserted into the base end of the locking plate 11 when the locking plate 11 is inserted into the slot 5 and then bent inward. 11 is formed by forming a fold 14b having a shape for urging 11 in the standing direction.

第２に、係止板１１の起立状態において、折目１４ｂを山形又は谷形に湾曲又は屈曲させて形成したことを特徴としている。   Secondly, in the standing state of the locking plate 11, the fold line 14b is formed to be bent or bent into a mountain shape or a valley shape.

第３に、折目１４ｂが鎖線又は破線状に間欠的に形成された切込線よりなることを特徴としている。   Thirdly, the fold line 14b is characterized by being formed by a cut line intermittently formed in a chain line or a broken line shape.

以上のように構成される本考案の構造によると、係止板の基端部において山形又は谷形の湾曲又は屈曲形成した折目を設けることによって、係止板を溝孔に挿入後、前記折目によって起立方向に戻る弾力が働き、係止板を溝孔に挿入した状態で係止固定することができるので、後の閉蓋作業等の箱組みが容易になる。   According to the structure of the present invention configured as described above, by providing a crease having a mountain-shaped or valley-shaped curve or bending at the base end portion of the locking plate, the locking plate is inserted into the slot, The elasticity that returns to the standing direction by the folds works, and the locking plate can be locked and fixed in a state of being inserted into the slot, so that the box assembly for the subsequent closing operation becomes easy.

また係止板を溝孔に挿入しフラップ片と左右側壁とを当接状態に保つことができるので、前壁及び前フラップを開放状態にしてケーキ等の内容物の出し入れをする際に、前端部が揺動状態のフラップ片によってケーキ等の内容物を傷つけることがなくなった。   In addition, since the locking plate can be inserted into the slot and the flap piece and the left and right side walls can be kept in contact with each other, when the front wall and the front flap are opened and the contents such as cake are taken in and out, the front end The flake pieces with the swinging part no longer damage the contents such as the cake.

以下本考案の実施形態を図面に基づき説明する。図１は本包装箱の箱組み完成状態を示す斜視図、図２は開蓋状態を示す斜視図、図３は内面展開図を示す。包装箱１は正方形又は長方形の底板２の相対する２組の辺に左右側壁３，４と前後壁６，７をそれぞれ折り曲げ起立可能に連設されている。前後壁６，７の上端には上部蓋を兼ねた前半部及び後半部の天板８を構成する前天板８ａと後天板８ｂが折り曲げ可能に連設されている。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a completed box assembly state of the present packaging box, FIG. 2 is a perspective view showing an opened state, and FIG. The packaging box 1 is connected to two opposing sides of a square or rectangular bottom plate 2 so that the left and right side walls 3 and 4 and the front and rear walls 6 and 7 can be bent upright. A front top plate 8a and a rear top plate 8b constituting the top plate 8 of the front half and the rear half that also serve as an upper lid are connected to the upper ends of the front and rear walls 6 and 7 so as to be bendable.

前後天板８ａ，８ｂの先端には折り曲げ起伏可能な把手９ａ，９ｂが各連設され、把手９ａ，９ｂの左右幅中央はゲート状に切欠かれている。その内部の切り残し部は、閉蓋時に互いに他方の把手の切欠部に挿通するように後方又は前方に突出する舌部１０が形成されている。該舌部１０は前後天板８ａ，８ｂの閉蓋時に互いに重なり合って、前後天板８ａ，８ｂ間の中央に隙間が生じるのを防止するものである。   Handles 9a and 9b that can be bent and undulated are connected to the front and rear top plates 8a and 8b, respectively, and the centers of the left and right widths of the handles 9a and 9b are notched in a gate shape. The inside uncut portion is formed with a tongue portion 10 that protrudes backward or forward so as to be inserted into the notch portion of the other handle when the lid is closed. The tongue portion 10 is overlapped with each other when the front and rear top plates 8a and 8b are closed to prevent a gap from being formed at the center between the front and rear top plates 8a and 8b.

上記把手９ａ，９ｂは、起立状態で互いに重なり合うように左右対称な同一形状をなし、左右両端には係止固定用の凹凸からなるフック部１２が各形成されている。後述するように閉蓋時に前後に重ね合わせた起立状態の把手９ａ，９ｂの左右両端のフック部１２が係止板１１の係止孔３０に挿通係止される構成となっている。   The grips 9a and 9b have the same symmetrical shape so as to overlap each other in the standing state, and hook portions 12 made of concave and convex portions for locking and fixing are formed at both left and right ends. As will be described later, the hook portions 12 at both the left and right ends of the handles 9a and 9b in the standing state that are overlapped in the front-rear direction when the lid is closed are inserted and locked in the locking holes 30 of the locking plate 11.

上記後壁７の両側端には、起立状態で左右の側壁３，４と重なり合って包装箱１の側壁を構成するフラップ片１３が連設され、該フラップ片１３の上端には舌状の係止板１１が折曲げ可能に連設されている。該フラップ片１３の幅は係止板１１の幅より広く形成されており、箱状にして持ち上げた場合にフラップ片１３の上端が溝孔５に引っ掛かることにより箱を変形させることなく持ち上げることができる。溝孔５は左右の側壁３，４上端側の略中央に穿設されている。   Flap pieces 13 constituting the side walls of the packaging box 1 are provided on both side ends of the rear wall 7 so as to overlap the left and right side walls 3 and 4 in an upright state. The stop plate 11 is continuously provided so that it can be bent. The width of the flap piece 13 is formed wider than the width of the locking plate 11. When the flap piece 13 is lifted in the shape of a box, the upper end of the flap piece 13 can be lifted without being deformed by being caught in the slot 5. it can. The slot 5 is formed in the approximate center on the upper end side of the left and right side walls 3 and 4.

溝孔５と幅が略同寸法の係止板１１には係止孔３０が設けられるとともに、舌状の係止片３１が折曲げ可能に連設されている。そして係止孔３０の下端には折目１４ａが設けられ、係止板１１の基端部には鎖線又は破線状に間欠的に形成された切込線からなる谷形（図３の内面展開図においては下向き）の湾曲した折目１４ｂが設けられている。   A locking hole 30 is provided in the locking plate 11 having substantially the same width as the groove 5, and a tongue-shaped locking piece 31 is continuously provided so as to be bent. The lower end of the locking hole 30 is provided with a fold 14a, and the base end portion of the locking plate 11 is formed in a valley shape (inner surface development in FIG. 3) formed by a cut line intermittently formed in a chain line or a broken line shape. A downwardly curved) fold 14b is provided.

図４に基づき折目１４ｂの作用について説明する。（Ａ）は起立状態の右側壁３とフラップ片１３及び係止板１１を示している。（Ｂ）に示すように右側壁３の溝孔５に挿通するために、（Ａ）状態から折目１４ｂを介して略水平方向（Ｆ1方向）に折り曲げると共に、フラップ片１３を右側壁３側（Ｆ2方向）に移動させる。この時、略水平方向（Ｆ1方向）に折曲げる力と係止板１１の起立方向（Ｒ方向）へ戻る弾力（反発力）は釣り合っている。 The operation of the fold line 14b will be described with reference to FIG. (A) shows the standing right side wall 3, the flap piece 13, and the locking plate 11. To insert the slot 5 of the right side wall 3 (B), the (A) to the state through the crease 14b with bending in a substantially horizontal direction (F 1 direction), the right side wall 3 of the flap piece 13 Move to the side (F 2 direction). At this time, elasticity (repulsive force) Back to the upright direction (R direction) of the force and the engaging plate 11 bending in a substantially horizontal direction (F 1 direction) are balanced.

そして（Ｃ）に示すように、フラップ片１３を右側壁３に重なり合う状態まで移動した（Ｆ2方向）後、（Ｂ）において略水平方向（Ｆ1方向）に折曲げていた力を止める。係止板１１には湾曲形成された谷形の折目１４ｂによって起立方向（Ｒ方向）に戻る弾力（反発力）が備っているので、右側壁３の溝孔５に挿通した後の係止板１１は、（Ｄ）に示すように右側壁３の外側（図４においては左側）より右側壁３に重なり合う。上記作用については左側壁４とフラップ片１３及び係止板１１との関係についても同様であるため説明を省略する。 And as shown in (C), after moved to the state overlapping the flap piece 13 on the right side wall 3 (F 2 direction), stop the force that has been bent in a substantially horizontal direction (F 1 direction) in (B). Since the locking plate 11 is provided with elasticity (repulsive force) that returns to the standing direction (R direction) by the curved valley-shaped fold 14b, the engagement plate 11 is inserted into the slot 5 in the right side wall 3. As shown in FIG. 4D, the stop plate 11 overlaps the right side wall 3 from the outside of the right side wall 3 (left side in FIG. 4). About the said effect | action, since it is the same also about the relationship between the left side wall 4, the flap piece 13, and the latching plate 11, description is abbreviate | omitted.

溝孔５は溝孔上端コーナー部５ａが角のあるアングル状に形成され、係止板１１を通した際に隙間なく係止固定できる構造となっている。よって係止板１１を溝孔５に貫通させると、上述の湾曲形成された谷形の折目１４ｂによる起立方向への戻る弾力との相互作用によって、フラップ片１３と左右側壁３，４との重合状態が維持され、後壁７とその両側で隣り合う左右側壁３，４とを確実に起立させることができる。   The slot 5 has a structure in which the slot upper end corner 5a is formed in an angled shape and can be locked and fixed without a gap when the locking plate 11 is passed through. Therefore, when the locking plate 11 is passed through the groove hole 5, the flap piece 13 and the left and right side walls 3 and 4 interact with each other by the elastic force returning to the standing direction by the above-described curved valley-shaped fold 14b. The polymerization state is maintained, and the rear wall 7 and the left and right side walls 3 and 4 adjacent to each other can be erected reliably.

前後の天板８ａ，８ｂの左右端には、天板閉蓋時において各係止板１１の前後の各側壁３，４の上端より左右両側に突出して各側壁３，４上端を覆うカバー部２３が各突設されている。よって箱組立状態で天板８ａ，８ｂ側のカバー部２３が側壁３，４上端を覆うことができるので、蓋の密閉性が向上すると共に、上蓋（天板８ａ，８ｂ）の箱内への入り込みも防止できる。   At the left and right ends of the front and rear top plates 8a and 8b, when the top plate is closed, a cover portion that protrudes from the upper ends of the front and rear side walls 3 and 4 to the left and right sides and covers the upper ends of the side walls 3 and 4 when the top plate is closed. Each protrusion 23 is provided. Therefore, since the cover part 23 on the top plate 8a, 8b side can cover the upper ends of the side walls 3, 4 in the assembled state of the box, the hermeticity of the lid is improved and the upper lid (top plates 8a, 8b) is put into the box. Intrusion can also be prevented.

左右側壁３，４の前端には、前フラップ２７が折り曲げ可能に連設され、該前フラップ２７の底面側前端には鉤状のフック部２８が形成されている。そして前壁６を起立させた時に、前フラップに形成されたフック部２８を上下に嵌合係止することにより、前壁６の左右端と側壁３，４の前端との間に隙間が形成されるのを防止すると共に、前壁６の後方移動を規制するものである。   A front flap 27 is connected to the front ends of the left and right side walls 3 and 4 so as to be bendable, and a hook-like hook portion 28 is formed at the bottom side front end of the front flap 27. When the front wall 6 is erected, a hook portion 28 formed on the front flap is fitted and locked up and down to form a gap between the left and right ends of the front wall 6 and the front ends of the side walls 3 and 4. In addition to preventing this, the rearward movement of the front wall 6 is restricted.

把手９ａ，９ｂの両端に設けられたフック部１２は凸部（突起部）１２ａと凹部（谷部）１２ｂから構成されている。凸部１２ａの上辺の両側コーナー部は円弧状に形成され、凸部１２ａの内側に設けられた凹部１２ｂは、略直線状の接当面が形成されている。またフック部１２の外側端の下辺には、前後天板８ａ，８ｂより外側に長く突出させた規制部２６が形成されている。   The hook portions 12 provided at both ends of the grips 9a and 9b are composed of a convex portion (projection portion) 12a and a concave portion (valley portion) 12b. The corners on both sides of the upper side of the convex portion 12a are formed in an arc shape, and the concave portion 12b provided inside the convex portion 12a has a substantially linear contact surface. Further, a restricting portion 26 is formed on the lower side of the outer end of the hook portion 12 so as to protrude longer than the front and rear top plates 8a and 8b.

天板閉蓋時には、前後に重ね合わせた起立状態の把手９ａ，９ｂの左右両端のフック部１２の凸部１２ａが、係止板１１の係止孔３０に挿通係止される。そして上記規制部２６が係止孔３０内で側壁３，４上端に当接して、把手９ａ，９ｂの下方移動を規制する構成となっている。さらに上記接当面に係止片３１が嵌入して当接係合する構成となっている。   When the top plate is closed, the convex portions 12a of the hook portions 12 at the left and right ends of the handles 9a and 9b in the standing state overlapped in front and rear are inserted and locked in the locking holes 30 of the locking plate 11. And the said control part 26 contact | abuts to the upper end of the side walls 3 and 4 within the locking hole 30, and becomes a structure which controls the downward movement of the handle 9a, 9b. Further, the locking piece 31 is fitted into the contact surface and is in contact with and engaged.

以上のように構成される包装箱１は、底板２と前壁６上に、左右側壁３，４，後壁７及び天板８等を折り畳んで重ね合わせた板状の状態で店頭等の現場へ出荷する（図示しない）。店頭等の現場では折り畳んだ板状の状態から、一旦図３に示す内面展開図状態に戻す。そしてフラップ片１３を起立方向に回動させた状態で後壁７を起立方向に回動させた後、左右側壁３，４を起立方向に回動させる   The packaging box 1 configured as described above is a shop floor or the like in a plate-like state in which the left and right side walls 3, 4, the rear wall 7, the top plate 8, and the like are folded on the bottom plate 2 and the front wall 6. (Not shown). At the shop floor or the like, the folded plate-like state is temporarily returned to the inner development view shown in FIG. Then, after the flap 13 is rotated in the standing direction, the rear wall 7 is rotated in the standing direction, and then the left and right side walls 3 and 4 are rotated in the standing direction.

図４の（Ａ）〜（Ｄ）に示すように、フラップ片１３の上端に連設された係止板１１を左右側壁３，４上端の溝孔５に挿入し図２に示される状態で係止固定する。前壁６と前天板８ａを一体的に前方に大きく開放した収容姿勢になるので、ケーキ等の収容物を円滑に収容することができる。   As shown in FIGS. 4A to 4D, the locking plate 11 connected to the upper end of the flap piece 13 is inserted into the slot 5 at the upper ends of the left and right side walls 3 and 4, and the state shown in FIG. Lock and fix. Since the housing posture is such that the front wall 6 and the front top plate 8a are integrally opened to the front, the accommodated items such as cakes can be accommodated smoothly.

収容した後、前フラップ２７を内側にアングル状に折り曲げてフック部２８により係止固定する。そして前天板８ａを持ち上げて後天板８ｂと合わせ、各把手９ａ，９ｂを接合状態で直立させる。係止板１１を把手９ａ，９ｂの外側方から折目１４ａを介して内向きに折り曲げて、フック部１２の凸部１２ａに挿通する。そして係止片３１を凹部１２ｂに嵌入係止させて箱組みを完了させる。   After the storage, the front flap 27 is bent inward at an angle and fixed by the hook portion 28. Then, the front top plate 8a is lifted and aligned with the rear top plate 8b, and the respective grips 9a and 9b are brought upright in the joined state. The locking plate 11 is bent inward from the outside of the grips 9a and 9b through the folds 14a and inserted into the convex portion 12a of the hook portion 12. Then, the locking piece 31 is fitted and locked in the recess 12b to complete the box assembly.

以上のように構成される本考案の包装箱における係止板の固定構造では、係止板１１の基端部に設けられた折目は湾曲形成されているが、屈曲形成も可能であるほか、折目の形状は山形にすることも可能である。また湾曲や屈曲に限らず係止板を左右側壁の溝孔に挿入後、起立方向に戻る弾力が係止板に備わるのであれば、折目１４ｂを他の態様にすることができる。さらに底板の形状も長方形又は正方形に限らず、直交方向に相対する２組の辺が存在する多角形であっても良い。その他、本包装箱の構造は上記態様に限らず他の態様にすることができる。   In the fixing structure of the locking plate in the packaging box of the present invention configured as described above, the fold provided at the base end portion of the locking plate 11 is formed in a curved shape, but it can also be bent. The shape of the fold can be a mountain shape. Further, the fold line 14b can be changed to another form as long as the locking plate is provided with elasticity that returns to the standing direction after the locking plate is inserted into the groove holes on the left and right side walls. Further, the shape of the bottom plate is not limited to a rectangle or a square, and may be a polygon having two sets of sides facing each other in the orthogonal direction. In addition, the structure of the present packaging box is not limited to the above aspect, and can be changed to other aspects.
