特許文献１の包装箱では、箱組立時に左右両側壁の前端が起立させた前壁内面と当接して箱内部と外部の密閉を確保すべき処、両側壁の前端に連結片９や切止片１１が連設されているため、保冷剤Ｄを収納して箱を組立てると、前壁が保冷剤に当接して側面視で湾曲することにより、側壁前端と前壁両側の内面との間に隙間が生じるため、保冷効果が損なわれるという欠点があるほか、持ち運び時に、外気と通じる隙間が生じることは埃や雑菌等の侵入原因ともなり望ましくない。 In the packaging box of Patent Document 1, the front ends of the left and right side walls should come into contact with the inner surface of the front wall that stands up when the box is assembled to ensure the sealing between the inside and the outside of the box. Since the pieces 11 are connected in series, when the box is assembled by storing the cold insulating agent D, the front wall abuts on the cold insulating agent and curves in a side view, so that the space between the front end of the side wall and the inner surfaces on both sides of the front wall is formed. In addition to the disadvantage that the cold insulation effect is impaired due to the formation of gaps in the space, the formation of gaps that communicate with the outside air during transportation is not desirable as it may cause intrusion of dust and germs.

また特許文献２の包装箱は、前壁３ａの上端にフラップ状の内前壁２９を連設して箱内側への折曲端を底板に接着固定しているので、上記のような前壁の湾曲による隙間は生じないが、接着固定の必要がある他、紙材が内前壁２９の上下幅分だけ前後方向に長くなり、材料裁断時の紙材料が増大する（コスト高）という問題がある。さらにこの形態のものでは、例えば本願添付の図１～４に示す把手付タイプの包装箱には適用できないという問題がある。 Further, in the packaging box of Patent Document 2, a flap-shaped inner front wall 29 is continuously provided at the upper end of the front wall 3a, and the bent end inside the box is adhesively fixed to the bottom plate, so that the front wall as described above is used. Although there is no gap due to the curvature of the paper, it is necessary to bond and fix it, and the paper material becomes longer in the front-back direction by the vertical width of the inner front wall 29, which increases the amount of paper material when cutting the material (high cost). There is. Further, this form has a problem that it cannot be applied to, for example, the handle-type packaging box shown in FIGS. 1 to 4 attached to the present application.

上記課題を解決するための本発明の包装箱は、第１に、四角形の底板２の前後左右の外周辺に周壁を折曲げ可能に連設し、いずれかの周壁に上部開口部を塞ぐ蓋８を折曲げ開閉可能に連設した包装箱であって、前壁３の左右両端に内側に折曲げて折曲端を内部で連結又は接合する収容フラップ１９を連設し、該収容フラップ１９と前壁３内面との間に保冷剤２１の収容部（２２）を形成することを特徴としている。 In the packaging box of the present invention for solving the above problems, first, a peripheral wall is foldably connected to the outer periphery of the front, rear, left and right sides of the rectangular bottom plate 2, and a lid that closes the upper opening to any of the peripheral walls is provided. A packaging box in which 8 is bent and opened and closed, and accommodating flaps 19 are continuously provided at both left and right ends of the front wall 3 by bending inward to connect or join the bent ends internally. It is characterized in that a storage portion (22) for the cold insulating agent 21 is formed between the surface and the inner surface of the front wall 3.

第２に、各収容フラップ１９を折曲げて連結又は接合した際に前壁３の内面との間に収容部２２内の前後幅を確保すべく、各収容フラップ１９の外側端側に所定幅のスペース側壁１９ａを上下方向に形成した
ことを特徴としている。 Secondly, in order to secure the front-rear width in the accommodating portion 22 between the accommodating flaps 19 and the inner surface of the front wall 3 when the accommodating flaps 19 are bent and connected or joined, a predetermined width is set on the outer end side of each accommodating flap 19. The space side wall 19a is formed in the vertical direction.

第３に、収容フラップ１９の上下端の少なくとも一方に収容部２２内側に折曲げて収容フラップ１９と前壁３内面間に収容部２２内の前後幅を保持する左右方向のスペースフラップ２４を連設したことを特徴としている。 Thirdly, a space flap 24 in the left-right direction that holds the front-rear width in the accommodating portion 22 is connected between the accommodating flap 19 and the inner surface of the front wall 3 by bending inward to the accommodating portion 22 at least one of the upper and lower ends of the accommodating flap 19. The feature is that it was installed.

第４に、左右の壁６，７の前端側に、周壁を起立させた箱組立状態で収容フラップ１９の基端部に当接するサポートフラップ１８を連設したことを特徴としている。 Fourth, on the front end side of the left and right walls 6 and 7, a support flap 18 that comes into contact with the base end portion of the accommodating flap 19 in a box-assembled state in which the peripheral wall is erected is continuously provided.

第５に、前後壁３，４の上端に箱組立状態で箱１の開口部前半部と後半部を各別に覆う前蓋８ａと後蓋８ｂをそれぞれ連設し、該前後蓋８ａ，８ｂの折曲端で起立させて重ね合わせて固定する把手９を設けたものにおいて、上記前蓋８ａと後蓋８ｂとの左右両側端に、閉じ蓋状態で左右壁６，７の上端を覆って開口部の左右上端の隙間を塞ぐカバーフラップ２７を下向きに折曲げ可能に連設してなることを特徴としている。 Fifth, a front lid 8a and a rear lid 8b that separately cover the front half and the rear half of the opening of the box 1 are continuously provided at the upper ends of the front and rear walls 3 and 4 in the box assembled state, and the front and rear lids 8a and 8b are provided. In the case where the handle 9 is provided so as to stand up at the bent end and be overlapped and fixed, the front lid 8a and the rear lid 8b are opened at both left and right ends so as to cover the upper ends of the left and right walls 6 and 7 in the closed lid state. It is characterized in that cover flaps 27 that close the gaps at the upper left and right ends of the portion are continuously provided so as to be bendable downward.

以上のように構成される本発明の包装箱によれば、次のような効果を奏する。
（１）収容部を形成する収容フラップが左右の側壁の前端に折曲げ可能に形成されて、前壁内面との間に保冷剤収容部が形成されるので、側壁前端と前壁両側端間に、保冷剤収容部に通じる外部との隙間が形成されず、冷気の損失や埃や雑菌等の侵入が防止され、前後壁の上端側に蓋や把手付のタイプの箱にも応用できる利点がある。また開蓋状態でのケーキ等の収容物の出し入れも容易である。 According to the packaging box of the present invention configured as described above, the following effects are obtained.
(1) Since the accommodating flap forming the accommodating portion is foldably formed at the front ends of the left and right side walls and the ice pack accommodating portion is formed between the accommodating portion and the inner surface of the front wall, the space between the front end of the side wall and both ends of the front wall is formed. In addition, there is no gap with the outside that leads to the ice pack storage part, and the loss of cold air and the intrusion of dust and germs are prevented, and the advantage that it can be applied to a box with a lid or handle on the upper end side of the front and rear walls. There is. In addition, it is easy to put in and take out items such as cakes with the lid open.

（２）左右のスペース側壁を左右側壁の高さ内に納め、又はその高さからの突出量を少なくすることにより、紙材からの材料取りのロスの発生を抑制できるほか、収容フラップ基端部のスペース側壁や上下端側に連設するスペースフラップにより、保冷剤の収容部の前後幅（厚み）が確実に確保され、保冷剤による前壁の湾曲も防止できる。 (2) By fitting the left and right space side walls within the height of the left and right side walls, or by reducing the amount of protrusion from that height, it is possible to suppress the occurrence of loss in material removal from the paper material, and the base end of the accommodating flap. The space flaps connected to the side wall of the space and the upper and lower ends ensure the front-rear width (thickness) of the ice pack accommodating portion, and the bending of the front wall due to the ice pack can be prevented.

（３）箱組立時に左右側壁前端に連設したサポートフラップが、収容部を構成する収容フラップの基端部内面に弾力的に当接するので、収容部形状がより安定的に保持できるほか、把手付きの蓋の場合、左右両側壁上端が隙間を生じることなく確実に閉蓋される利点がある。 (3) Since the support flaps connected to the front ends of the left and right side walls when assembling the box elastically abut on the inner surface of the base end of the accommodating flaps constituting the accommodating portion, the shape of the accommodating portion can be held more stably and the handle. In the case of a lid with a lid, there is an advantage that the upper ends of the left and right side walls are securely closed without creating a gap.

図１～図５は把手付の包装箱に関する第１実施形態を、図６～図９は把手なしの直方体状の包装箱に関する第２実施形態をそれぞれ示しており、先ず第１実施形態につき説明する。第１実施形態のケーキ類包装用箱の直方体形の箱１は、四角形の底板２の四辺にそれぞれ折曲げ起立可能な前後の周壁（前壁３，後壁４）、左右の周壁（左壁６，右壁７）を連設し、前後の周壁３，４の上端には前後に分割形成され、箱１の上部の開口部を塞ぐ蓋８（前蓋８ａ，後蓋８ｂ）がそれぞれ折曲げ可能に連設されている。 1 to 5 show a first embodiment of a packaging box with a handle, and FIGS. 6 to 9 show a second embodiment of a rectangular cuboidal packaging box without a handle. First, the first embodiment will be described. do. The rectangular cuboid box 1 of the cake packaging box of the first embodiment has front and rear peripheral walls (front wall 3, rear wall 4) and left and right peripheral walls (left wall) that can be bent and erected on the four sides of the rectangular bottom plate 2, respectively. 6, Right walls 7) are connected in series, and the lids 8 (front lid 8a, rear lid 8b) that are divided into front and rear parts at the upper ends of the front and rear peripheral walls 3 and 4 and close the opening at the top of the box 1 are folded. It is connected in a bendable manner.

上記前蓋８ａと後蓋８ｂの開閉端には、組立状態で直立して互に前後重ね合わされる正面視ゲート状の把手９がそれぞれ折曲げ可能に連設されており、この例では箱組立時に互に他方の把手９のゲート内に挿入され上下に重ねり合う舌部１１が、左右の中間位置に突出するように前後蓋８ａ，８ｂの先端に突設されている。 At the open / closed ends of the front lid 8a and the rear lid 8b, front-view gate-shaped handles 9 that stand upright in the assembled state and are overlapped with each other in the front-rear direction are connected in series so as to be bendable. In this example, the box is assembled. The tongue portions 11 which are sometimes inserted into the gate of the other handle 9 and overlap each other vertically are projected from the tips of the front and rear lids 8a and 8b so as to project to the intermediate positions between the left and right.

後壁４の左右両端には四角形の補助フラップ１２がそれぞれ折曲げ可能に連設されており、各補助フラップ１２の（箱組立状態の）上端には、前記前後の把手９の左右端を係脱可能に挿入係止する山形の係止フラップ１３がそれぞれ上向きに且つ内向き折曲げ可能に突設されている。係止フラップ１３による前後の把手９の起立状態の係止は、係止フラップ１３側に切込形成した係止孔１５に把手９の左右両端のフック部９ａを係脱可能に挿入して行う古くからの周知の機構による。 Square auxiliary flaps 12 are connected to the left and right ends of the rear wall 4 so as to be bendable, and the left and right ends of the front and rear handles 9 are engaged with the upper end (in the box assembled state) of each auxiliary flap 12. The chevron-shaped locking flaps 13 that are detachably inserted and locked are projecting upward and inwardly so as to be bendable. The front and rear handles 9 are locked in an upright state by the locking flaps 13 by inserting hook portions 9a at both left and right ends of the handles 9 into the locking holes 15 cut and formed on the locking flaps 13 side so as to be detachable. By a well-known mechanism from ancient times.

上記補助フラップ１２は、箱組立状態では起立した後壁８ｂとともにその左右端で、左右壁６，７の内面に沿って前向きに起立する。他方左右壁６，７の後端側上部コーナーには三角形状ののり代（のり付部）１４が形成され、上記補助フラップ１２内面の重ね合せ面と一体的に接着されて左右壁６，７の起立姿勢を固定的に補助する。 The auxiliary flap 12 stands forward along with the rear wall 8b that stands up in the box-assembled state at the left and right ends thereof along the inner surfaces of the left and right walls 6 and 7. On the other hand, a triangular glue margin (glue portion) 14 is formed at the upper corner on the rear end side of the left and right walls 6 and 7, and is integrally adhered to the overlapping surface of the inner surface of the auxiliary flap 12 to be integrally bonded to the left and right walls 6 and 7. It assists the standing posture of.

また上記補助フラップ１２は、各のり代１４の三角形の斜辺に沿った左右壁６，７側に付した斜め方向の折目１６を介して左右壁６，７及び後壁４を同時に内向きに（底板２に重ねるように）折畳み開閉するのを案内する役割を果たしている。そして補助フラップ１２の下端と左右壁６，７の下端の組立時の対応位置には、左右壁６，７の起立状態を保持するように互に挿脱し合う爪部を差込孔（切込孔）からなる係脱部１７ａ，１７ｂが形成されている。上記左右壁６，７の前端には、箱組立時に前壁８ａの左右端内面側に当接する上下方向のフラップ（後述するサポートフラップ）１８が折曲げ可能に連接されている。 Further, the auxiliary flap 12 simultaneously makes the left and right walls 6, 7 and the rear wall 4 inward through the diagonal creases 16 attached to the left and right walls 6 and 7 along the diagonal side of the triangle of each glue margin 14. It plays the role of guiding the folding and opening (so that it overlaps with the bottom plate 2). Then, at the corresponding positions of the lower end of the auxiliary flap 12 and the lower ends of the left and right walls 6 and 7 at the time of assembly, a claw portion that is inserted and removed from each other so as to maintain the standing state of the left and right walls 6 and 7 is inserted into a hole (cut). The disengagement portions 17a and 17b made of holes) are formed. Vertical flaps (support flaps, which will be described later) 18 that come into contact with the inner surface side of the left and right ends of the front wall 8a during box assembly are foldably connected to the front ends of the left and right walls 6 and 7.

上記のような箱１の基本構造は従来一般的に採用されてきた公知のものであるが、本発明の包装箱においては前壁３の左右両端に内向きに折曲げ（畳み）可能な収容フラップ１９が連設されている。該収容フラップ１９はその連設基端部の台形状のスペース側壁１９ａと、その台形状の短辺側に折目２０を介して折曲げ可能に連設される四角形の内壁１９ｂとからなり、一方の内壁１９ｂの先端（内端）には舌状の差込片１９ｃが、他方の内壁１９ｂには差込片１９ｃを差込む差込孔１９ｄが折目２０上に形成されている。 The basic structure of the box 1 as described above is a known one that has been generally adopted in the past, but in the packaging box of the present invention, the front wall 3 can be bent (folded) inward at both left and right ends. The flaps 19 are connected in series. The accommodating flap 19 is composed of a trapezoidal space side wall 19a at the continuous base end portion and a rectangular inner wall 19b connected to the short side of the trapezoidal shape so as to be bendable via a crease 20. A tongue-shaped insertion piece 19c is formed at the tip (inner end) of one inner wall 19b, and an insertion hole 19d into which the insertion piece 19c is inserted is formed on the other inner wall 19b.

収容フラップ１９は互に内側に折曲げられてその先端を重ね合せて差込片１９ｃを他方の差込孔１９ｄに差込むことにより、左右の収容フラップ１９は互に連設されて前壁３の内面との間に平面視台形状スペースからなる収容部２２が形成され、この収容部２２に上方から保冷材２１（図３参照）が挿入収容される。２３は内壁１９ｂに形成された冷気流通孔である。 The accommodation flaps 19 are bent inward from each other, and the tips thereof are overlapped with each other, and the insertion piece 19c is inserted into the other insertion hole 19d. An accommodating portion 22 composed of a plan view trapezoidal space is formed between the accommodating portion 22 and the accommodating portion 22, and the cold insulating material 21 (see FIG. 3) is inserted and accommodated in the accommodating portion 22 from above. Reference numeral 23 is a cold air flow hole formed in the inner wall 19b.

スペース側壁１９ａは図１，図３に示すように収容部２２の前後幅（厚み）を形成する役目を果たし、また内壁１９ｂの上端には上記のように形成された収容部２２の前後幅に相当する幅のスペースフラップ２４が内向き折曲げ可能に連設されていて、組立状態ではこのスペースフラップ２４も収容部２２の上端において収容部２２の前壁３の内面と収容フラップ１９の間にあって収容部２２上部の前後幅を保持すべく機能する。 The space side wall 19a serves to form the front-rear width (thickness) of the accommodating portion 22 as shown in FIGS. 1 and 3, and the front-rear width of the accommodating portion 22 formed as described above is formed at the upper end of the inner wall 19b. Space flaps 24 having a corresponding width are connected in series so as to be bendable inward, and in the assembled state, the space flaps 24 are also located at the upper end of the accommodating portion 22 between the inner surface of the front wall 3 of the accommodating portion 22 and the accommodating flap 19. It functions to maintain the front-rear width of the upper part of the accommodating portion 22.

収容部２２の下端は箱１の内部に開放・連通して冷気流通路となるほか、スペース側壁１９ａと内壁１９ｂの間の折目部分には、両者の折曲げを容易にし折曲げ状態で箱内部と収容部２２が連通（冷気流通）するように円弧状の切込孔２６が上下方向に切込形成されている。 The lower end of the accommodating portion 22 opens and communicates with the inside of the box 1 to form a cold air passage, and the fold portion between the space side wall 19a and the inner wall 19b makes it easy to bend both of them and the box is in a bent state. An arcuate notch hole 26 is formed in the vertical direction so that the inside and the accommodating portion 22 communicate with each other (cold air flow).

上記のように組み立てられる収容部２２は、前壁３を起立させると、収容フラップ１９のスペース側壁１９ａは、左右壁６，７の前端に連設したフラップ（サポートフラップ）１８に弾力的に当接し、収容フラップ１９が安定的に起立姿勢を保持し、収容部２２の左右両側も塞がれて冷気漏れも生じない。なお、左右の収容フラップ１９ｂの先端側の重ね合せ面には、図４に示すようにのり代（のり付部）２５を形成して、図１のように重ね合わせた際に両フラップ１９ｂ同士を接着して固定的に連結することもできる。 When the front wall 3 is erected in the accommodating portion 22 assembled as described above, the space side wall 19a of the accommodating flap 19 elastically hits the flaps (support flaps) 18 continuously provided at the front ends of the left and right walls 6 and 7. In contact with each other, the accommodating flap 19 stably maintains an upright posture, and the left and right sides of the accommodating portion 22 are also closed so that cold air does not leak. A glue margin (glue portion) 25 is formed on the superposed surface on the tip side of the left and right accommodating flaps 19b as shown in FIG. 4, and both flaps 19b are overlapped with each other as shown in FIG. Can also be bonded and fixedly connected.

また前後の蓋８ａ，８ｂの左右両側端には前後方向の帯状のカバーフラップ２７が内向き（下向き）に折曲げ可能に連設されており、箱組立状態で下向きに折曲げることにより、箱１の側壁６，７の上端に被さって、図１，２に示すように箱１の左右両端を塞ぐ構造になっている。 In addition, strip-shaped cover flaps 27 in the front-rear direction are connected to the left and right ends of the front and rear lids 8a and 8b so that they can be bent inward (downward). As shown in FIGS. 1 and 2, the structure is such that the upper ends of the side walls 6 and 7 of 1 are covered and the left and right ends of the box 1 are closed.

さらに後壁４の両端には上下方向のジッパー２８が上下方向に形成され、組立状態で内部に収容したケーキ等の収容物を取り出す際には、係止フラップ１３より外した把手９を後蓋８ｂと共に後方斜め上方に引張ることにより、このジッパー２８位置で後壁８ｂの大半が両端で切り裂かれ、後部を開口させてその開口部より収容物を取り出すことができる。 Further, vertical zippers 28 are formed at both ends of the rear wall 4, and when taking out the contained items such as cakes contained therein in the assembled state, the handle 9 removed from the locking flap 13 is attached to the rear cover. By pulling diagonally upward and backward together with 8b, most of the rear wall 8b is torn at both ends at this zipper 28 position, and the rear part can be opened and the contents can be taken out from the opening.

図５は上記把手付の箱１をプレート状に折畳んだ状態を示し、箱組立前に補助フラップ１２，左右側壁６，７，収容フラップ１９を共に内側に折畳み（この時のり代１４により補助フラップ１２と左右両側壁６，７は共に接着されている）、前後壁８ａ，８ｂを交互に底板２上に重ねながら折畳むことができる。箱１は使用前のこの状態で保管流通し、使用時には図１，図２の状態に順次組立てられる。 FIG. 5 shows a state in which the box 1 with the handle is folded into a plate shape, and the auxiliary flaps 12, the left and right side walls 6, 7 and the accommodating flaps 19 are all folded inward before the box is assembled (assisted by the glue 14 at this time). The flaps 12 and the left and right side walls 6 and 7 are both adhered to each other), and the front and rear walls 8a and 8b can be folded while being alternately stacked on the bottom plate 2. Box 1 is stored and distributed in this state before use, and when used, it is sequentially assembled in the states shown in FIGS. 1 and 2.

図６～図９は前記把手９を設けない形態の箱に本発明の収容部２２の構造を適用した実施形態（第２実施形態）を示しており、把手９を設けないことにより蓋８は単一の蓋を構成することができ、把手９自体と把手９を支持する前記係止フラップ１３等が必要ない点、蓋８が単一に構成されることにより蓋８の閉じ状態での係脱構造等が必要な点以外は、すべて前記図１～図５の構造と共通である。そして前記実施形態と共通部分は共通の符号で示しており、共通部分についての説明は割愛する。 6 to 9 show an embodiment (second embodiment) in which the structure of the accommodating portion 22 of the present invention is applied to a box in which the handle 9 is not provided, and the lid 8 is formed by not providing the handle 9. A single lid can be configured, and the handle 9 itself and the locking flap 13 that supports the handle 9 are not required. Except for the point that destructuring is required, all the structures are the same as those in FIGS. 1 to 5. The common parts with the above-described embodiment are indicated by common reference numerals, and the description of the common parts will be omitted.

以下第２実施形態の特徴部分につき説明すると、蓋８は底板２と略同形の長方形であり、その後端は後壁８ｂの上端に折曲げ可能に連設されており、前端と左右両端には蓋８の周壁を形成する蓋周壁８ｃ（前壁），８ｄ，８ｄ（側壁）が折曲げ可能に連設されている。 Hereinafter, the feature portion of the second embodiment will be described. The lid 8 is a rectangle having substantially the same shape as the bottom plate 2, and the rear end is foldably connected to the upper end of the rear wall 8b, and the front end and the left and right ends are connected to each other. The lid peripheral walls 8c (front wall), 8d, and 8d (side walls) forming the peripheral wall of the lid 8 are connected in a row so as to be bendable.

上記蓋周壁の前壁８ｃの左右両端には連結フラップ２９が折曲げ可能に連設されており、これを内向きに折曲げて外周面を左右の側壁８ｄの後端内面に形成した三角形状ののり代３１に重ねて接着することにより、蓋８は周壁８ｃ，８ｄを起立させた状態で箱型に組立てられる。上記のり代３１の斜辺部に沿って形成した折目３２によって、箱型の蓋は周壁８ｃ，８ｄを蓋８の内面と重ねて内向きに折畳むことができる。 Connecting flaps 29 are connected to the left and right ends of the front wall 8c of the lid peripheral wall so as to be bendable, and the outer peripheral surface is formed on the inner surface of the rear end of the left and right side walls 8d by bending inward.
