Description

この発明は、解体後、折り畳んだ状態でロックできる段ボール箱に関するものである。   The present invention relates to a cardboard box that can be locked in a folded state after being disassembled.

従来、長面の側板及び短面の側板を各一対交互に連設して周壁を形成し、各側板にそれぞれ封緘用のフラップを連設した段ボール箱において、周壁の対角に位置する稜線に沿って二重に折り畳んだ状態で、一方の重合面をなすフラップに係合片を、他方の重合面をなすフラップに係合穴をそれぞれ切込により設け、係合片を係合穴に押し込んで、折畳状態を維持するようにしたロック機構付きのものが提案されている（下記特許文献１参照）。   Conventionally, in a corrugated cardboard box in which a long side plate and a short side plate are alternately connected to each other to form a peripheral wall, and a sealing flap is connected to each side plate, a ridge line located diagonally to the peripheral wall is provided. In the state of being folded twice along, the engaging piece is provided in the flap forming one overlapping surface, the engaging hole is provided in the flap forming the other overlapping surface, and the engaging piece is pushed into the engaging hole. Thus, a device with a lock mechanism that maintains the folded state has been proposed (see Patent Document 1 below).

しかしながら、大型の段ボール箱では、上記のようなロック機構を設けても、十分に小さく折り畳むことができず、廃棄に伴う家庭での一時保管や再生回収品の集積場への運搬等に際し、嵩張って取り扱いにくいという問題がある。   However, a large cardboard box cannot be folded sufficiently small even if it is provided with a lock mechanism as described above, and is bulky for temporary storage at home due to disposal or transportation of recycled and recovered items to a collection site. There is a problem that it is difficult to handle.

そこで、この発明は、嵩張らないように折り畳んだ状態で容易に廃棄できる折畳ロック付き段ボール箱を提供することを課題とする。   Then, this invention makes it a subject to provide the corrugated cardboard box with a folding lock which can be easily discarded in the state folded so that it may not become bulky.

上記課題を解決するため、この発明は、長面の側板及び短面の側板を各一対交互に連設して周壁を形成し、各側板にそれぞれ封緘用のフラップを連設した段ボール箱において、全フラップを開き、周壁の対角に位置する稜線に沿って二重に折り畳んだ状態で、一方の重合面をなす長面のフラップに、他方の重合面をなす長面と短面のフラップ間の溝に一致する折目線を入れ、この折目線に沿って四重に折り畳んだ状態を維持するロック機構を設けたのである。   In order to solve the above problems, the present invention provides a corrugated cardboard box in which a long side plate and a short side plate are alternately connected to each other to form a peripheral wall, and a sealing flap is connected to each side plate. With all flaps open and folded in double along the ridge line located on the diagonal of the peripheral wall, between the long flap that forms one overlap surface and the long and short flaps that form the other overlap surface A crease line that coincides with the groove is inserted, and a lock mechanism is provided that maintains the folded state along the crease line.

また、前記ロック機構として、対のフラップを切り込んで係合片及び係合穴を設け、四重に折り畳んだ状態で、間に挟まれるフラップの切欠部を介して係合片を係合穴に押し込むようにしたのである。   In addition, as the locking mechanism, a pair of flaps are cut to provide an engagement piece and an engagement hole, and the engagement piece is made into an engagement hole via a notch portion of the flap sandwiched between the four in a folded state. I tried to push it in.

さらに、前記ロック機構の係合片に、撓みを容易にする斜め方向の折目線を入れ、係合穴の両側縁に設けた扉片の反発により、巻き込むように折り曲げた係合片が係合穴から抜け止めされるようにしたのである。   Furthermore, an oblique crease line is provided in the engagement piece of the lock mechanism to facilitate bending, and the engagement piece bent so as to be wound is engaged by the repulsion of the door pieces provided on both side edges of the engagement hole. It was designed to be secured from the hole.

この折畳ロック付き段ボール箱は、長面のフラップに入れた折目線に沿って簡単に四重に折り畳むことができ、ロック機構によりその折畳状態を維持できるので、廃棄に伴う一時保管や運搬に際し、嵩張ることがなく、容易に取り扱うことができる。   This cardboard box with folding lock can be easily folded in quadruple along the fold line in the long flap, and the folded state can be maintained by the lock mechanism. At this time, it is not bulky and can be handled easily.

以下、この発明の実施形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１に示すように、この段ボール箱のブランクでは、長面の側板１及び短面の側板２が各一対交互に連設され、一方の側板１の外側には継代片３が連設されている。側板１，２の上下端にはそれぞれフラップ４，５が連設され、一方の側板１の上下に繋がるフラップ４には、縦方向の折目線６が切刃により入れられている。折目線６の位置は、このフラップ４と隣り合うフラップ５との間の溝からフラップ５の幅だけ離れている。   As shown in FIG. 1, in this cardboard box blank, a pair of long side plates 1 and short side plates 2 are alternately connected to each other, and a passage piece 3 is connected to the outside of one side plate 1. ing. Flaps 4 and 5 are connected to the upper and lower ends of the side plates 1 and 2, respectively, and a vertical crease line 6 is inserted by a cutting blade in the flap 4 connected to the upper and lower sides of one side plate 1. The position of the crease line 6 is separated from the groove between the flap 4 and the adjacent flap 5 by the width of the flap 5.

上側の一方のフラップ４には係合片７が、他方のフラップ４には係合穴８がそれぞれ先端からの切込により設けられている。係合片７には、撓みを容易にするため、２本の斜め方向の折目線９が先端へ向けて間隔が狭くなるように入れられ、係合穴８の両側縁には扉片１０が設けられている。   One upper flap 4 is provided with an engaging piece 7 and the other flap 4 is provided with an engaging hole 8 by cutting from the tip. In order to make the engagement piece 7 easy to bend, two diagonal crease lines 9 are inserted toward the tip so that the distance between the crease line 9 becomes narrower, and door pieces 10 are formed on both side edges of the engagement hole 8. Is provided.

上側の一方のフラップ５の先端縁には、指入用の切欠部１１が設けられ、他方のフラップ５の外角部には、係合片７を通過させる切欠部１２が設けられている。また、側板２には把手穴１３が設けられている。   A notch 11 for inserting a finger is provided at the leading edge of one upper flap 5, and a notch 12 through which the engagement piece 7 is passed is provided at the outer corner of the other flap 5. The side plate 2 is provided with a handle hole 13.

上記のようなブランクを箱に組み立てるには、図２に示すように、各一対の側板１，２を角筒状に折り曲げ、継代片３を反対側の側板２に貼り付けて周壁を形成する。そして、物品の梱包に際し、フラップ４，５により底面及び天面を封緘する。   To assemble the blank as described above into a box, as shown in FIG. 2, each pair of side plates 1 and 2 is bent into a square tube shape, and the passage piece 3 is attached to the opposite side plate 2 to form a peripheral wall. To do. Then, when packing the article, the bottom surface and the top surface are sealed with the flaps 4 and 5.

一方、上記段ボール箱を解体して廃棄する際には、まず、天面及び底面の全てのフラップ４，５を開き、図３に示すように、周壁の対角に位置する稜線に沿って二重に折り畳んだ状態とする。このとき、一方の重合面をなすフラップ４の折目線６が、他方の重合面をなすフラップ４，５間の溝に一致する。   On the other hand, when dismantling and discarding the cardboard box, first, all the flaps 4 and 5 on the top and bottom surfaces are opened, and as shown in FIG. Let it be in a folded state. At this time, the crease line 6 of the flap 4 forming one overlapping surface coincides with the groove between the flaps 4 and 5 forming the other overlapping surface.

次に、図４に示すように、折目線６に沿って段ボール箱を四重に折り畳むと、段ボール箱は、外側の隣り合うフラップ４，５の抵抗を受けることなく、所定の位置で折り曲げられ、コンパクトな状態となる。   Next, as shown in FIG. 4, when the cardboard box is folded fourfold along the crease line 6, the cardboard box is folded at a predetermined position without receiving the resistance of the adjacent flaps 4 and 5 outside. It becomes a compact state.

その後、指入部１１から指を入れて、係合片７を巻き込むように折り曲げると、係合片７は、折目線９に沿って撓みつつ、切欠部１２を介して扉片１０を押し開き、係合穴８に押し込まれて、扉片１０の反発により、係合穴８から抜け止めされる。   Thereafter, when a finger is inserted from the finger insertion portion 11 and bent so as to wind the engagement piece 7, the engagement piece 7 is bent along the crease line 9 while pushing the door piece 10 through the notch portion 12. When the door piece 10 is pushed into the engagement hole 8 and is repelled, it is prevented from coming off from the engagement hole 8.

このように、上記段ボール箱は、折目線６に沿って簡単に四重に折り畳むことができ、係合片７と係合穴８とから成るロック機構により折畳状態が確実に維持されるので、廃棄に伴う一時保管や運搬に際し、嵩張ることがなく、容易に取り扱うことができる。   Thus, the cardboard box can be easily folded fourfold along the fold line 6, and the folded state is reliably maintained by the lock mechanism including the engagement piece 7 and the engagement hole 8. It can be easily handled without being bulky during temporary storage and transportation associated with disposal.

なお、この実施形態では、折目線６として、切刃により入れたものを例示したが、折目線６は、押罫としてもよい。また、上下のフラップ４に入れた折目線６を繋ぐように、一方の側板１に押罫を入れてもよい。   In this embodiment, the crease line 6 is illustrated by a cutting blade, but the crease line 6 may be a ruled line. Moreover, you may put a ruled line in one side plate 1 so that the crease line 6 put in the upper and lower flaps 4 may be connected.

そのほか、係合片７と係合穴８とから成るロック機構は、上側だけでなく、上下両方のフラップ４に設けてもよく、対のフラップ５に係合片７と係合穴８とを設け、その間に挟まれるフラップ４に切欠部１２を設けてもよい。   In addition, the locking mechanism including the engagement piece 7 and the engagement hole 8 may be provided not only on the upper side but also on both the upper and lower flaps 4. The engagement piece 7 and the engagement hole 8 are provided on the pair of flaps 5. The notch 12 may be provided in the flap 4 that is provided and sandwiched therebetween.

また、係合片７及び係合穴８は、フラップ４又は５を先端側から切り込んで設けるのではなく、フラップ４又は５の内部を切り込んで設けてもよい。   Further, the engaging piece 7 and the engaging hole 8 may be provided by cutting the inside of the flap 4 or 5 instead of cutting the flap 4 or 5 from the tip side.
