Abstract

<P>PROBLEM TO BE SOLVED: To easily assemble a one-touch bottom assembled corrugated cardboard box while retaining a crime prevention performance. <P>SOLUTION: The one-touch bottom assembled corrugated cardboard box is configured as described below. A peripheral wall is formed by connecting a pair of side plates 1 and a pair of end plates 2 via ridges, and bottom side plates 4 and bottom end plates 5 are extended from the lower ends of the side plates 1 and end plates 2 respectively. An angular crease 6 for folding is formed in one end of each bottom side plate 4. By forming the peripheral wall into a rectangular tubular shape from a flat folded state, the engaging portions 8 of the leading ends of the bottom side plates 4 engage with each other to form a bottom, the tongue 10 provided at each engaging portion 8 is pushed over the bottom side plate 4 of the opposite bottom side plate while its being bent and undone along an oblique lines 9, thereby preventing separation of the engaging portions 8. In such a corrugated cardboard box, the outer end edge of each tongue 10 is obliquely cut so as to retreat toward the corresponding engaging end, thereby forming an inclined edge 11. When the tongues 10 abut on each other during the assembly of the bottom, both the tongues 10 are folded along the oblique lines 9 while sliding along the inclined edges 11. As the engaging portions 8 engage with each other, the tongues 10 return to their original shapes from their folded states. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

この発明は、様々な商品の包装に使用可能で、折り畳んだ状態から即時に組み立てることができるワンタッチ底組式段ボール箱に関するものである。   The present invention relates to a one-touch bottom corrugated cardboard box that can be used for packaging various products and can be immediately assembled from a folded state.

従来、ワンタッチ式の箱底として、下記特許文献１には、図７及び図８に示すようなものが記載されている。この箱のブランクでは、図７に示すように、側板５１と端板５２とが稜部の罫線を介し隣り合うように各一対交互に並び、一方の側板５１の外側端には継代片５３が連設され、各側板５１の下端には底側板５４が、各端板５２の下端には底端板５５がそれぞれ連設されている。   Conventionally, as a one-touch type box bottom, the following Patent Document 1 describes the one shown in FIGS. 7 and 8. In the blank of this box, as shown in FIG. 7, the side plates 51 and the end plates 52 are alternately arranged in pairs so as to be adjacent to each other via the ruled lines of the ridges. The bottom side plate 54 is connected to the lower end of each side plate 51, and the bottom end plate 55 is connected to the lower end of each end plate 52.

各底側板５４の一端には、底面のコーナーへ向かう斜め方向の角折線５６を介して固着片５７が連設され、各底側板５４の先端中央部には、切込を入れて噛合部５８が設けられている。噛合部５８には、底側板５４の先端縁から噛合部５８の奥側へ至る斜折線５９を介して舌片６０が設けられ、舌片６０の外端縁は先端側が迫り出すように傾斜している。   A fixing piece 57 is continuously provided at one end of each bottom side plate 54 via a diagonal fold line 56 directed toward the corner of the bottom surface. Is provided. The meshing portion 58 is provided with a tongue piece 60 via an oblique fold line 59 extending from the tip edge of the bottom plate 54 to the back side of the meshing portion 58, and the outer edge of the tongue piece 60 is inclined so that the tip side protrudes. ing.

この箱を製造する際には、ブランクを折り重ねることにより、継代片５３を反対側の端板５２の裏面に貼り付けて、周壁となる部分を形成すると共に、底側板５４及び底端板５５を上方へ折り曲げ、固着片５７を角折線５６に沿って折り返し、底端板５５に貼り付けて、扁平な折畳状態としておく。   When this box is manufactured, the blank piece is folded to attach the passage piece 53 to the back surface of the opposite end plate 52 to form a peripheral wall, and the bottom side plate 54 and the bottom end plate 55 is bent upward, the fixing piece 57 is folded back along the square fold line 56, and is attached to the bottom end plate 55 to be in a flat folded state.

そして、組み立てに際し、図８に示すように、扁平な折畳状態から周壁を角筒状に形成すると、底側板５４同士が噛合部５８で噛み合って底組みされる。このとき、舌片６０を斜折線５９に沿って一旦上方へ折り曲げ、噛合部５８を噛み合わせた後、舌片６０を復元させ、互いに他方の底側板５４に乗り上げさせて、噛合部５８の分離を阻止する。   Then, when assembling, as shown in FIG. 8, when the peripheral wall is formed in a rectangular tube shape from a flat folded state, the bottom side plates 54 are engaged with each other at the engagement portion 58 and assembled. At this time, the tongue piece 60 is once bent upward along the oblique line 59 and meshed with the meshing portion 58, and then the tongue piece 60 is restored to ride on the other bottom side plate 54 to separate the meshing portion 58. To prevent.

このように箱底を有する箱で商品を包装すると、外部から底側板５４を押して、底側板５４の先端部間に隙間を開け、箱内の商品を抜き取ろうとしても、底側板５４の噛合部５８での噛み合わせを解除することができず、隙間を開けることができないので、商品の抜き取りを防止することができる。   When products are packaged in a box having a box bottom in this way, even if an attempt is made to push out the bottom plate 54 from the outside to open a gap between the front end portions of the bottom plate 54 and take out the product in the box, the meshing portion of the bottom plate 54 Since the engagement at 58 cannot be released and a gap cannot be formed, it is possible to prevent the product from being removed.

しかしながら、撓ませて底組みし難い剛性の高い段ボール箱で上記のような箱底を採用すると、組み立てに際し、一対の舌片６０を手で折り曲げつつ、周壁を角筒状としなければならず、作業性がよくないという問題がある。   However, if the box bottom as described above is adopted in a highly corrugated cardboard box that is bent and difficult to assemble, the pair of tongue pieces 60 must be bent by hand while assembling, and the peripheral wall must be formed into a rectangular tube shape. There is a problem that it is not good.

そこで、この発明は、ワンタッチ底組式の段ボール箱を、防犯性を維持しつつ、簡単に組み立てられるようにすることを課題とする。   Accordingly, an object of the present invention is to make it possible to easily assemble a one-touch bottom assembly type cardboard box while maintaining crime prevention.

上記課題を解決するため、この発明は、側板と端板とを稜部を介し各一対連設して周壁を形成し、側板及び端板の下端からそれぞれ底側板及び底端板を延出し、底側板の一端部に折畳用の角折線を設け、扁平な折畳状態から周壁を角筒状に形成すると、底側板同士が先端側の噛合部で噛み合って底組みされ、噛合部に設けられた舌片が斜折線に沿って屈伸しつつ互いに他方の底側板に乗り上げて、噛合部の分離が阻止されるワンタッチ底組式段ボール箱において、前記舌片の外端縁に、噛合端側へかけて後退するように斜めに切断した傾斜縁を形成し、底組み時に舌片同士が当接すると、傾斜縁に沿って舌片同士が滑りつつ斜折線に沿って折れ曲がり、噛合部の噛み合いに伴い、舌片の折れ曲がりが復元するようにしたのである。   In order to solve the above problem, the present invention forms a peripheral wall by connecting a pair of side plates and end plates via ridges, and extends the bottom side plates and bottom end plates from the lower ends of the side plates and end plates, respectively. When folding corner folding lines are provided at one end of the bottom side plate and the peripheral wall is formed in a rectangular tube shape from a flat folded state, the bottom side plates are engaged with each other at the engagement portion on the front end side, and assembled at the engagement portion. In the one-touch bottom assembly type corrugated cardboard box in which the separated tongue pieces are bent and stretched along the oblique line and ride on the other bottom side plates to prevent separation of the meshing portion, the outer edge of the tongue piece is connected to the meshing end side Inclined edges that are cut diagonally so as to recede toward the bottom, and when tongues come into contact with each other at the time of bottom assembly, the tongues slide along the inclined edges and bend along the oblique lines, and the meshing parts engage. Along with this, the bending of the tongue was restored.

また、前記底側板に、舌片の噛合端側からその底側板の基端側へ向けて誘導切目を入れたのである。   In addition, a guide cut is made in the bottom side plate from the meshing end side of the tongue piece toward the base end side of the bottom side plate.

この発明に係るワンタッチ底組式段ボール箱では、扁平な折畳状態から周壁を角筒状とするだけで、一対の舌片が自動的に折れ曲がり、噛合部の噛み合い後に復元するので、舌片を手で折り曲げる必要がなく、簡単に底組みすることができる。   In the one-touch bottom corrugated cardboard box according to the present invention, the pair of tongue pieces are automatically bent and restored after meshing of the meshing portion only by making the peripheral wall into a rectangular tube shape from a flat folded state. There is no need to bend it by hand and it can be easily assembled.

そして、その組立状態で、舌片により噛合部の分離が阻止されて、商品の抜き取りが防止され、確実な防犯性が得られる。   In the assembled state, separation of the meshing portion is prevented by the tongue piece, the product is prevented from being pulled out, and reliable crime prevention is obtained.

また、底側板に舌片の噛合端側から誘導切目を入れたことにより、噛合部の噛み合いを無理に外そうとすると、誘導切目から底側板が破断し、商品を抜き取ろうとした痕跡が明確に残るため、流通過程での犯罪を検知することができる。   In addition, when the guide cut is made in the bottom side plate from the engagement end side of the tongue piece, if the engagement of the engagement portion is forcibly removed, the bottom plate is broken from the guide cut and the trace of trying to remove the product is clear. Therefore, it is possible to detect crimes in the distribution process.
