特許文献１や２のものは、夫々差し込み片をスリットに挿入させて封止又はロックさせる構造として開封しにくい構造となっているが、差し込み片やスリットの形状構成が複雑であり、製造に手間がかかるものである。 Patent Documents 1 and 2 each have a structure that is difficult to open as a structure in which an insertion piece is inserted into a slit to seal or lock it, but the shape configuration of the insertion piece and the slit is complicated, and it is troublesome to manufacture. It takes.

そこで、この考案は上記の課題を解決するために、極めて簡単な構造でありながら、蓋を本体部に被せて、差し込み片をスリットに挿入すると、容易に開けることができず、開閉する際は開口部から紙をちぎってロックを解除することにより蓋をあける、不正混入防止機能付き包装用箱を提供することを目的としたものである。 Therefore, in order to solve the above-mentioned problems, this device has an extremely simple structure, but when the lid is put on the main body and the insertion piece is inserted into the slit, it cannot be easily opened and when opening and closing, The purpose is to provide a packaging box with an unauthorized mixing prevention function, which opens the lid by tearing the paper from the opening and unlocking it.

請求項１の考案は、箱本体部と、蓋体部とから成り、四辺形の底板の各辺から側板を立ち上げてこれらの側板が相互に接続された箱本体部の背面に位置する側板の上縁が蓋体部の四角形の天板の一辺に折り目を介して接続され、当該蓋体部の天板の他の３辺から蓋体側板が夫々垂下され、これらの蓋体側板は相互に接続され、当該蓋体部を前記箱本体部の側板に被せる包装用箱において、蓋体部の正面の蓋体側板の下端縁から折り目を介して差し込み片を突設し、また、箱本体部の正面側板の底板との折り目近くに、前記差し込み片を挿入する、当該差し込み片の幅より短い長さの直線状のスリットを設け、前記蓋体部の差し込み片の上方の蓋体側板に、切り取りガイド透孔を設けた、不正混入防止機能付き包装用箱とした。 The invention of claim 1 is composed of a box main body portion and a lid body portion, and side plates are located on the back surface of the box main body portion in which side plates are raised from each side of a quadrilateral bottom plate and these side plates are connected to each other. The upper edge is connected to one side of the square top plate of the lid portion via a crease, and the lid side plates are hung from the other three sides of the top plate of the lid portion. In a packaging box that is connected to the lid and covers the side plate of the box body, an insertion piece is projected from the lower end edge of the lid side plate in front of the lid through a crease, and the box body is also provided. Near the crease with the bottom plate of the front side plate of the portion, a linear slit having a length shorter than the width of the insertion piece for inserting the insertion piece is provided in the lid side plate above the insertion piece of the lid portion. , A packaging box with a cut-out guide through hole and a function to prevent unauthorized mixing.

また、請求項２の考案は、前記差し込み片は前記蓋体側板の下端縁近くの基部が内側に鋭角にすぼまった形状であり、前記スリットはその両端が斜めに折れ曲がって切り込まれた、請求項１に記載の不正混入防止機能付き包装用箱とした。 Further, according to the second aspect of the present invention, the insertion piece has a shape in which the base portion near the lower end edge of the lid side plate is narrowed inward at an acute angle, and both ends of the slit are cut diagonally. , The packaging box with the fraudulent mixing prevention function according to claim 1.

また、請求項３の考案は、前記差し込み片は両側部が横に突出した突出片部とし、先端部が先細りとなった形状である、請求項１又は２に記載の不正混入防止機能付き包装用箱とした。 The invention of claim 3 is the packaging with an unauthorized mixing prevention function according to claim 1 or 2, wherein the insertion piece has a protruding piece portion having both sides protruding laterally and a tapered tip portion. It was a box.

また、請求項４の考案は、前記切り取りガイド透孔は、前記差し込み片と平行に形成され、当該切り取りガイド透孔の両端から差し込み片の両端基部まで当該蓋体側板にミシン目状切り取り孔を設けた、請求項１～３のいずれかに記載の不正混入防止機能付き包装用箱とした。 Further, in the invention of claim 4, the cut-out guide through-hole is formed in parallel with the insertion piece, and a perforated cut-out hole is formed in the lid side plate from both ends of the cut-out guide through-hole to the bases of both ends of the insert piece. The packaging box provided with the fraudulent mixing prevention function according to any one of claims 1 to 3 was used.

請求項１の考案によれば、箱本体部に蓋体部を被せ、差し込み片の両側端を少し折り曲げるか差し込み片の一側からスリットに斜めに入れて当該差し込み片をスリットに挿入すると、差し込み片の幅がスリットの幅より大きいため、差し込み片はスリットに係止されてむやみに外れず、蓋体部はロックされる。この状態では差し込み片のほぼ全部がスリットに入っているため、差し込み片の基部がわずかに露出しているだけで、蓋体部及び箱本体部の外側に突起物や凹部がほとんどなく、当該箱を開封する手がかりがない。従って、第三者が不正に開封できず、箱本体部に異物を混入することができない。また、当該包装用箱に入れた商品の抜き取りや差し替えもできず、不正混入防止機能を有している。 According to the invention of claim 1, when the box body is covered with the lid and the both ends of the insertion piece are slightly bent or the insertion piece is slanted into the slit from one side of the insertion piece and the insertion piece is inserted into the slit, the insertion piece is inserted. Since the width of the piece is larger than the width of the slit, the insertion piece is locked to the slit and does not come off unnecessarily, and the lid portion is locked. In this state, almost all of the insertion piece is in the slit, so the base of the insertion piece is only slightly exposed, and there are almost no protrusions or recesses on the outside of the lid and the box body, and the box is concerned. There is no clue to open the package. Therefore, a third party cannot open the box illegally, and foreign matter cannot be mixed into the box body. In addition, the products in the packaging box cannot be removed or replaced, and have a function to prevent unauthorized mixing.

また、当該包装用箱の収納商品を取り出す場合は、切り取りガイド透孔に指を入れて、当該正面の蓋体側板を外方に引っ張ると切り取りガイド透孔から蓋体側板がち切れ、前記差し込み片が蓋体部から切り離され、蓋体部を箱本体部から外すことができる。この様にしなければ蓋体部は開かず、不正に当該包装用箱の蓋体部を開けると、一目で不正開封が発覚する。 When taking out the stored product of the packaging box, put a finger in the cut-out guide through hole and pull the front lid side plate outward to cut off the lid side plate from the cut-out guide through hole, and the insertion piece. Is separated from the lid body portion, and the lid body portion can be removed from the box body portion. If this is not done, the lid will not open, and if the lid of the packaging box is opened illegally, unauthorized opening will be discovered at a glance.

また、請求項２の考案によれば、差し込み片をスリットに挿入する際は、当該差し込み片の両側を、スリットの両端の斜めに折り曲がった形状に合わせて折り曲げて夫々挿入すれば、差し込み片はその基部の鋭角にすぼまった箇所までスリットに挿入できる。一方、挿入後は該差し込み片のすぼまった箇所より先端の部分の折れ曲がりが復元されて差し込み片は全面がほぼ平面となり、差し込み片の両側がスリットの両端の折り曲げ部の上方の蓋体側板に当って係止される。その状態では差し込み片の鋭角なすぼみ部がスリットに嵌るため、当該差し込み片はがたつくことがなく、より完全にロックされる。従って、差し込み片を単に外方に引っ張るだけではスリットから外れない。 Further, according to the invention of claim 2, when inserting the insertion piece into the slit, if both sides of the insertion piece are bent according to the diagonally bent shape at both ends of the slit and inserted respectively, the insertion piece is inserted. Can be inserted into the slit up to the point where the base is narrowed to an acute angle. On the other hand, after the insertion, the bending of the tip portion is restored from the recessed part of the insertion piece, the entire surface of the insertion piece becomes almost flat, and both sides of the insertion piece are the lid side plates above the bent portions at both ends of the slit. It hits and is locked. In that state, since the acute-angled recessed portion of the insertion piece fits into the slit, the insertion piece does not rattle and is locked more completely. Therefore, simply pulling the insertion piece outward does not remove it from the slit.

また、請求項３の考案によれば、蓋体部の正面の蓋体側板の下縁から突設した差し込み片は両側部が横に突出した突出片部を有し、その突出部から先端部にかけて先細り、その基部が内側に鋭角にすぼまって前記正面側板の下端縁に至る形状のため、差し込み片の先端が先細形状となって前記スリットに挿入しやすい。また、差し込み片の基部の鋭角にすぼまった箇所まで差し込み片をスリットに入れた後は、蓋体部の正面の蓋体側板を外側に引っ張っても、差し込み片の両端の突出片部がスリットの両端の折り曲げ部の上方の蓋体側板に当って係止され、差し込み片がスリットから外れない。 Further, according to the third aspect of the present invention, the insertion piece projecting from the lower edge of the lid side plate on the front surface of the lid portion has a protruding piece portion whose both sides protrude laterally, and the tip portion from the protruding portion. Since the base portion is tapered inward to reach the lower end edge of the front side plate, the tip of the insertion piece has a tapered shape and is easily inserted into the slit. In addition, after inserting the insertion piece into the slit to the point where the base of the insertion piece is squeezed to a sharp angle, even if the lid side plate on the front of the lid is pulled outward, the protruding pieces at both ends of the insertion piece will be exposed. It is locked by hitting the lid side plate above the bent portion at both ends of the slit, and the insertion piece does not come off from the slit.

また、請求項４の考案によれば、前記切り取りガイド透孔の両端から差し込み片の両端基部まで当該蓋体側板にミシン目状切り取り孔を設けているため、当該包装用箱の蓋体部を箱本体部から外す際、前記切り取りガイド透孔に指を掛けて正面側板を外側に引っ張ると、前記ミシン目状切り取り孔がガイドとなってそこから切れて、その箇所の蓋体側板がち切れ、前記差し込み片が蓋体部から切り離される。従って、開封が容易にできる。 Further, according to the invention of claim 4, since the perforated cutting hole is provided in the lid side plate from both ends of the cutting guide through hole to the bases of both ends of the insertion piece, the lid portion of the packaging box is provided. When removing from the box body, if the front side plate is pulled outward by putting a finger on the cutting guide through hole, the perforated cutting hole serves as a guide and cuts from there, and the lid side plate at that location is cut off. The insertion piece is separated from the lid body portion. Therefore, it can be easily opened.

この台紙から不正混入防止機能付き包装用箱Ａを組み立てるには、箱本体部１の底板３の四辺の側板４を夫々立ち上げ、折り込み舌片７を左右の側板４の内側に折り曲げ、また、折り込み舌片１０を前記左右の側板４の内側に折り曲げ、夫々左右の側板４の内側に各折り込み舌片７及び１０を貼着する。その上から左右の側板４の上端縁から各折り返し縁片８を内側に折って対応する側板４の内側に貼着する。これにより箱本体部１が組み立てられる。 In order to assemble the packaging box A with an unauthorized mixing prevention function from this mount, the side plates 4 on the four sides of the bottom plate 3 of the box body 1 are raised, and the folded tongue pieces 7 are bent inward of the left and right side plates 4. The folded tongue pieces 10 are bent inside the left and right side plates 4, and the folded tongue pieces 7 and 10 are attached to the insides of the left and right side plates 4, respectively. From above, each folded edge piece 8 is folded inward from the upper end edge of the left and right side plates 4 and attached to the inside of the corresponding side plate 4. As a result, the box body 1 is assembled.

また、蓋体部２は、天板５の三辺の蓋体側板６を夫々天板５から立ち上げ、折り込み舌片１１を左右の蓋体側板６の内側に折り、対向する蓋体側板に貼着する。これにより蓋体部２が形成され、図１に示す箱本体部１と蓋体部２が組み立てられる。 Further, in the lid portion 2, the lid side plates 6 on the three sides of the top plate 5 are raised from the top plate 5, and the folded tongue pieces 11 are folded inside the left and right lid side plates 6 to form the facing lid side plates. Stick it on. As a result, the lid body portion 2 is formed, and the box body portion 1 and the lid body portion 2 shown in FIG. 1 are assembled.

そして、蓋体部２を箱本体部１に被せてロックするには、蓋体部２を箱本体部１の背面の側板４の上端縁から折り曲げて図３に示すように、箱本体部１の各側板４の外側に蓋体部２の各蓋体側板６を被せる。そして、図４及び図８に示すように、蓋体部２の正面側の蓋体側板６の下端縁から突出した差し込み片１２を箱本体部１の側板４の下端縁近くのスリット９に挿入し、図５に示すように、差し込み片１２の基部までスリット９に挿入する。この差し込み片１２をスリット９に挿入する際は、差し込み片９の両側の突出片部１２ａを折り曲げスリット部９ａに合わせて折り曲げるか又は差し込み片１２の片側からスリット９に斜めに差し込めば挿入が可能である。 Then, in order to cover the lid body 2 on the box body 1 and lock it, the lid 2 is bent from the upper end edge of the side plate 4 on the back surface of the box body 1 and the box body 1 is bent as shown in FIG. Each lid side plate 6 of the lid portion 2 is covered with the outside of each side plate 4 of the above. Then, as shown in FIGS. 4 and 8, the insertion piece 12 protruding from the lower end edge of the lid side plate 6 on the front side of the lid portion 2 is inserted into the slit 9 near the lower end edge of the side plate 4 of the box body 1. Then, as shown in FIG. 5, the insertion piece 12 is inserted into the slit 9 up to the base.

スリット９への挿入後は差し込み片１２の両側の突出片部１２ａが復元力で平らに戻ってスリット９の側方まで伸び、折り曲げスリット部９ａの上方の側板４の内側に当たって、図９に示すように係止され、また図７に示すように、差し込み片１２の基部が鋭角なすぼまり部１２ｃとなってスリット９に嵌るため、差し込み片１２は内で動かず、ロックされる。この状態では差し込み片１２の基部がわずかに見えるだけで、蓋体部２及び箱本体部１の外側に突起物や凹部がほとんどなく、当該箱を開封することが出来ない。 After insertion into the slit 9, the protruding piece portions 12a on both sides of the insertion piece 12 return flat due to the restoring force and extend to the side of the slit 9, and hit the inside of the side plate 4 above the bent slit portion 9a, as shown in FIG. As shown in FIG. 7, since the base of the insertion piece 12 becomes an acute-angled narrowed portion 12c and fits into the slit 9, the insertion piece 12 does not move inside and is locked. In this state, the base of the insertion piece 12 is only slightly visible, and there are almost no protrusions or recesses on the outside of the lid 2 and the box body 1, and the box cannot be opened.

この箱を開封するには、蓋体部２の蓋体側板６の切り取りガイド透孔１３に指を掛けて外方に引っ張ると、ミシン目状切り取り孔１４から蓋体側板６が切れて前記切り取りガイド透孔１３とミシン目状切り取り孔１４で囲まれた部分が切り取られて前記差し込み片１２は蓋体側板６から切り離される。そこで蓋体部２を箱本体部１から開くことが出来、開封される。 To open this box, put a finger on the cut-out guide through hole 13 of the lid body side plate 6 of the lid body portion 2 and pull it outward, and the lid side plate 6 is cut from the perforated cut-out hole 14 and the cut-out is performed. The portion surrounded by the guide through hole 13 and the perforated cut hole 14 is cut off, and the insertion piece 12 is separated from the lid side plate 6. Therefore, the lid body portion 2 can be opened from the box body portion 1 and opened.
