Description

本発明は、食品、飲料、医薬品等を収納する包装用箱に関するものであって、特に使用後の廃棄において、容易に扁平状に折り畳んで廃棄することができる包装用箱に関するものである。 The present invention relates to a packaging box for storing food, beverages, medicines, and the like, and particularly to a packaging box that can be easily folded into a flat shape for disposal after use.

従来より、食品、飲料、医薬品等を収納する包装用箱において、後処理が容易となるよう、適宜の箇所にミシン目等の破断線を形成した包装用箱が公知である。 2. Description of the Related Art Conventionally, packaging boxes for storing foods, beverages, pharmaceuticals, and the like are well known in the packaging box in which break lines such as perforations are formed at appropriate locations so as to facilitate post-processing.

例えば、四枚の側板から四角筒状に形成された胴部と、胴部の両側開口部をそれぞれ閉鎖するように、側板に連設して形成した蓋板とからなる包装箱において、蓋板の内、一方の蓋板は、側板に内蓋板折目を介して連設して形成した内蓋板と、内蓋板に重ねて貼着され、側板に外蓋板折目を介して連設して形成した外蓋板とからなり、側板には、外蓋板折目に沿って折り曲げられる押切部を区画するように、側板側に突出させて押切用破断線を形成すると共に、外蓋板には、押切用破断線の両端からそれぞれ連続して外蓋板の各側縁に至るように切開用破断線を形成し、内蓋板には、外蓋板に重ねて貼着された状態で、切開用破断線とほぼ重なる部位に易折曲線を形成し、一方、蓋板の内、他方の蓋板には、再施蓋可能な上蓋部、差し込み片、摘み片、貼着部を順次連設して形成した包装用箱が公知である（特許文献１参照）。 For example, in a packaging box consisting of a barrel formed from four side plates in a square cylinder shape and a lid plate formed continuously to the side plates so as to close both side openings of the barrel, One of the cover plates is attached to the side plate by overlapping the inner cover plate formed by connecting the inner cover plate through the inner cover plate fold, and is attached to the side plate via the outer cover plate fold. It consists of an outer lid plate formed continuously, and on the side plate, it is projected to the side plate side so as to define a pressing portion that is bent along the outer lid plate fold, and a breaking line for pressing is formed. On the outer lid plate, cut lines for incision are formed so as to reach each side edge of the outer lid plate continuously from both ends of the breaking line for press-cutting. In this state, an easy-folding curve is formed at a portion almost overlapping with the incision breaking line. On the other hand, on the other lid plate, an upper lid portion that can be re-covered and an insertion piece The tab, box packaging which is formed by sequentially continuously provided the bond portion is known (see Patent Document 1).

実用新案登録第３１２００６４号Utility model registration No. 3120064

上記構造では、通常、包装用箱を開封する際、摘み片を開封用破断線に沿って破断して切り離して、上蓋部と差し込み片とを胴部から開放するものである。そして、包装用箱を廃棄する際には、押切部を手指で押圧して、押切用破断線に沿って押切部を胴部の内側に押し込み、切開用破断線に沿って破断することで、内蓋板とともに外蓋板を胴部から開放し、胴部を扁平に折り畳んで廃棄するものである。 In the above structure, usually, when the packaging box is opened, the knob piece is broken and cut along the breaking line for opening, and the upper lid portion and the insertion piece are opened from the trunk portion. And when discarding the packaging box, press the pressing part with your fingers, push the pressing part inside the trunk part along the breaking line for pressing, and break along the breaking line for incision, The inner lid plate and the outer lid plate are opened from the trunk, and the trunk is folded flat and discarded.

しかしながら、当該包装用箱を上記のように通常の開封方法で行うと、開封時に摘み片が廃棄対象物となってしまう。また、包装用箱の内部には、内容物等を記載した説明書等の添付書類が略コ字状に折曲して挿入されていることから、当該添付書類を取り出さなければ、収納物を取り出すことができない上、当該添付書類も廃棄対象物となってしまう。このように、通常の開封方法で開封すると、収納物を取り出す為に２つの廃棄対象物が出ることになる。これらの廃棄対象物は、通常下における使用においては特段問題とされることなく廃棄されるものである。 However, if the packaging box is subjected to a normal opening method as described above, the pick piece becomes an object to be discarded at the time of opening. In addition, since attached documents such as instructions describing the contents etc. are bent and inserted in a substantially U shape inside the packaging box, the stored items must be taken out if the attached documents are not removed. In addition to being unable to take out, the attached document becomes a waste object. In this way, when the container is opened by a normal opening method, two objects to be discarded come out to take out the stored items. These waste objects are discarded without any particular problem in normal use.

しかしながら、医療機関等の緊急を要する通常下以外の状況においては、開封時に上記２つの廃棄対象物を取り出す必要がある為、開封作業が煩雑なものとなる虞がある。 However, in situations other than normal situations requiring urgency, such as a medical institution, it is necessary to take out the two objects to be discarded at the time of opening, so that the opening operation may be complicated.

このような事情に鑑みて、通常下以外の状況においては、上記のような通常の開封方法を行わず、包装用箱の廃棄の際に使用する押切部を用いて、包装用箱の底部側から開封作業が行われている。これにより、摘み片、添付書類といった、通常下以外の状況において不要とされる廃棄対象物を出すことなく、収納物のみを取り出すことができる。 In view of such circumstances, the bottom side of the packaging box is used in situations other than under normal conditions, without using the usual opening method as described above, and using the pressing part used when discarding the packaging box. Opening work has been carried out. As a result, it is possible to take out only the stored items without taking out the objects to be discarded, such as a pick piece and an attached document, which are not required in situations other than the normal situation.

一方で、包装用箱の底部側から開封作業を行ったものについて、廃棄する際には、摘み片を開封用破断線に沿って破断して切り離して、上蓋部と差し込み片とを胴部から開放し、胴部を扁平に折り畳んで廃棄するものであるが、係る場合であっても、通常下以外の状況においては、摘み片が不要な廃棄対象物となってしまうものであった。 On the other hand, when discarding the one that has been opened from the bottom side of the packaging box, when discarding, the cutting piece is broken along the breaking line for opening, and the upper lid portion and the insertion piece are separated from the trunk portion. It is opened and the body is folded and discarded flat, but even in such a case, the pick piece becomes an unnecessary disposal object in a situation other than the normal bottom.

そこで、本発明はこのような問題点を解決するものであって、食品、飲料、医薬品等を収納した包装用箱を日常等の通常下の状況で使用する場合においては、特段問題とされることのない程度の廃棄対象物を出すことになるが、医療機関等の緊急を要する通常下以外の状況で使用する場合においては、廃棄対象物を出すことなく、容易に開封作業及び廃棄作業を行うことができる包装用箱を提供することを課題とする。 Therefore, the present invention solves such problems, and is particularly problematic when a packaging box containing food, beverages, medicines, etc. is used in a normal situation such as daily life. However, when using it in a situation other than the normal situation that requires urgency, such as a medical institution, it is easy to open and dispose of it without taking out the waste object. It is an object to provide a packaging box that can be used.

Thus, the mechanical strength of the second perforation portion 16 is set, and the knob piece 15 and the sticking piece 17 are thereby separated. At this time, the mechanical strength is set so that the first perforation portion 14 does not break even with substantially the same pressing force.

すなわち、第１ミシン目部１４は、摘み片１５からの開封時に生じる左右方向の付加力によってのみ破断されるものであり、第２ミシン目部１６は、当該左右方向の付加力、並びに、対向する側板側への前後方向の付加力によっても破断されるものである。 That is, the 1st perforation part 14 is fractured only by the lateral force applied when opening from the knob 15 and the second perforation 16 is applied to the lateral force and the opposite direction. It is also broken by the applied force in the front-rear direction on the side plate side.

第１ミシン目部１４は、第１切込部１８と第１繋ぎ部１９が交互に連続することで構成される。当該第１ミシン目部１４は、開封手段として用いられる公知の形状を採用するものであり、特に限定されるものではなく、第１切込部１８は、例えば、略直線状、略円弧状等から形成される。 The 1st perforation part 14 is comprised by the 1st cut | notch part 18 and the 1st connection part 19 continuing alternately. The said 1st perforation part 14 employ | adopts the well-known shape used as an opening means, and is not specifically limited, For example, the 1st notch part 18 is substantially linear, substantially arc shape, etc. Formed from.

第１繋ぎ部１９は、摘み片１５を開封方向へ引っ張った際に、破断される箇所のことである。具体的には、第１切込部１８の終端から隣接する第１切込部１８の始端までの間隙とされる。このとき、第１切込部１８の形状によっては、第１ミシン目部１４の終端から隣接する始点までの間隙とは別途の繋ぎ部を形成する場合もある。本実施例においては、これらの繋ぎ部のうち、開封方向に沿って形成されるものを第１繋ぎ部１９とする。また、複数の繋ぎ部が形成される場合であって、いずれも開封方向に沿って形成されない場合には、短い方の寸法の繋ぎ部を第１繋ぎ部１９とする。
The first connecting portion 19 is a portion to be broken when the knob 15 is pulled in the opening direction. Specifically, it is a gap from the end of the first cut portion 18 to the start end of the adjacent first cut portion 18. At this time, depending on the shape of the first cut portion 18, a connecting portion may be formed separately from the gap from the end of the first perforation portion 14 to the adjacent start point. In the present embodiment, among these connecting portions, the first connecting portion 19 is formed along the opening direction. Further, when a plurality of connecting portions are formed and none of them is formed along the opening direction, the connecting portion having the shorter dimension is set as the first connecting portion 19.

例えば、図２及び図３に示すように、個々の第１切込部１８が摘み片１５側に向けて略く字状に屈曲するよう形成されるとき、開封方向に沿って形成される繋ぎ部を有することから、第１繋ぎ部１９は、当該屈曲中心から隣接する第１切込部１８の始端までの間隙とされる。 For example, as shown in FIGS. 2 and 3, when each of the first cut portions 18 is formed to be bent in a substantially square shape toward the knob piece 15, the connection formed along the opening direction. Since the first connecting portion 19 has the portion, the first connecting portion 19 is a gap from the bent center to the start end of the adjacent first cut portion 18.

また、第２ミシン目部１６は、第２切込部２０と第２繋ぎ部２１が交互に連続することで構成される。当該第２ミシン目部１６においても、第１ミシン目部１４と同様、公知の形状を採用することができる。 Moreover, the 2nd perforation part 16 is comprised by the 2nd notch part 20 and the 2nd connection part 21 continuing alternately. Also in the second perforation part 16, a known shape can be adopted as in the first perforation part 14.

本実施例においては、個々の第２切込部２０は、直線部から延設されるとともに、摘み片１５側に向けて湾曲する湾曲部を有して形成される。当該湾曲部は、図２及び図３に示すように、略く字状、略円弧状、略曲線状等から形成されていればよく、特に制限されるものではない。湾曲部は、貼着部１７を対向する側板側へ押圧することで、第２ミシン目部１６が容易に破断するように、摘み片１５側に形成されていればよい趣旨である。更に、第２切込部２０においては、湾曲部を設けることなく、略直線状のみから構成するものであってもよいのは勿論である。 In the present embodiment, each of the second cut portions 20 is formed to have a curved portion that extends from the straight portion and curves toward the knob 15 side. As shown in FIGS. 2 and 3, the curved portion is not particularly limited as long as it is formed in a substantially square shape, a substantially arc shape, a substantially curved shape, or the like. The curved portion is only required to be formed on the side of the knob 15 so that the second perforation portion 16 is easily broken by pressing the sticking portion 17 toward the opposing side plate. Furthermore, the second cut portion 20 may be configured only from a substantially straight line without providing a curved portion.

第２繋ぎ部２１は、摘み片１５を開封方向へ引っ張った際に、破断される箇所のことである。具体的には、第２切込部２０の終端から隣接する第２切込部２０の始端までの間隙とされる。その他、第２繋ぎ部２１の定義については、第１繋ぎ部１９の場合と同様である。 The 2nd connection part 21 is a location broken when the knob 15 is pulled in the opening direction. Specifically, it is a gap from the end of the second notch 20 to the start of the adjacent second notch 20. In addition, the definition of the second connecting portion 21 is the same as that of the first connecting portion 19.

このようにして形成される第１ミシン目部１４及び第２ミシン目部１６においては、第１切込部１８、第１繋ぎ部１９、第２切込部２０及び第２繋ぎ部２１が夫々実寸法を満足させるようにして、摘み片１５における幅方向の範囲にて形成される。ここで、実寸法とは、摘み片１５の両端縁部により途中で分断されることのない実際の長さ寸法のことをいう。特に、第１切込部１８及び第２切込部２０においては、湾曲部をも含み、切込まれた全長さ寸法のことをいう。すなわち、夫々が整数倍の個数で形成されるものである。そして、摘み片１５においては、当該一端縁部から夫々が整数倍の個数で形成されるが、摘み片１５の幅寸法が夫々の整数倍に該当しない場合には、当該他端縁部において、適宜の長さ寸法の切込部２２、繋ぎ部２３が形成されるものである。 In the 1st perforation part 14 and the 2nd perforation part 16 formed in this way, the 1st notch part 18, the 1st connection part 19, the 2nd notch part 20, and the 2nd connection part 21 are each respectively. It is formed in the range in the width direction of the knob 15 so as to satisfy the actual dimension. Here, the actual dimension refers to an actual length dimension that is not divided in the middle by both end edges of the knob 15. In particular, in the 1st notch part 18 and the 2nd notch part 20, the curved part is included and it means the full length dimension cut. That is, each is formed with an integer multiple. And, in the knob piece 15, each is formed from the one end edge in an integral multiple, but when the width dimension of the knob 15 does not correspond to each integer multiple, in the other edge, A cut portion 22 and a connecting portion 23 having appropriate length dimensions are formed.

また、第２ミシン目部１６を対向する側板側への前後方向に破断するとの観点から、第２切込部２０の個数は奇数倍を形成することが望ましい。更に、湾曲部を有する第２切込部２０にあっては、当該湾曲部を摘み片１５における幅方向（左右方向）の略中央部近郊に位置させることが望ましい。 Further, from the viewpoint of breaking the second perforation portion 16 in the front-rear direction toward the opposing side plate, it is desirable that the number of the second cut portions 20 be an odd multiple. Furthermore, in the second cut portion 20 having a curved portion, it is desirable to locate the curved portion in the vicinity of the substantially central portion in the width direction (left-right direction) of the knob 15.

ここで、同図における第１切込部１８の実寸法をａとし、第１繋ぎ部１９の実寸法をｂとする。また、第２切込部２０の実寸法をｃとする。そして、複数の第２繋ぎ部２１のうち、摘み片１５における幅方向（左右方向）の略中央部近郊に位置する第２繋ぎ部２１の実寸法をｄとし、その他の第２繋ぎ部２１の実寸法をｅとする。 Here, the actual dimension of the first notch 18 in the figure is a, and the actual dimension of the first joint 19 is b. In addition, the actual dimension of the second cut portion 20 is c. Of the plurality of second connecting portions 21, the actual dimension of the second connecting portion 21 located near the central portion in the width direction (left-right direction) of the knob 15 is d, and the other second connecting portions 21 Let e be the actual dimension.

このとき、第１切込部１８の実寸法ａを第２切込部２０の実寸法ｃより短く設定するとともに、第１繋ぎ部１９の実寸法ｂを第２繋ぎ部２１の実寸法ｄより長く設定する。また、略中央部近郊に位置する第２繋ぎ部２１の実寸法ｄをその他の第２繋ぎ部２１の実寸法ｅより長く設定する。更に、第１切込部１８及び第１繋ぎ部１９の個数は、第２切込部２０及び第２繋ぎ部２１の個数と同等数、又は同等数より多く形成される。これにより、第１ミシン目部１４と第２ミシン目部１６の機械的強度の夫々を異なるものとすることができる。 At this time, the actual dimension a of the first notch 18 is set shorter than the actual dimension c of the second notch 20, and the actual dimension b of the first connecting part 19 is set from the actual dimension d of the second connecting part 21. Set longer. Further, the actual dimension d of the second connecting portion 21 located in the vicinity of the substantially central portion is set longer than the actual dimensions e of the other second connecting portions 21. Further, the number of the first cut portions 18 and the first connecting portions 19 is equal to or more than the number of the second cut portions 20 and the second connecting portions 21. Thereby, each of the mechanical strength of the 1st perforation part 14 and the 2nd perforation part 16 can be made different.

本実施例においては、例えば、第１切込部１８の実寸法ａを約６ｍｍとし、第２切込部２０の実寸法ｃを約１０〜１１ｍｍとする。また、第１繋ぎ部１９の実寸法ｂを約２ｍｍとし、略中央部近郊に位置する第２繋ぎ部２１の実寸法ｄを約１ｍｍとし、その他の第２繋ぎ部２１の実寸法ｅを約０．５ｍｍとする。 In the present embodiment, for example, the actual dimension a of the first cut portion 18 is about 6 mm, and the actual dimension c of the second cut portion 20 is about 10 to 11 mm. Further, the actual dimension b of the first connecting portion 19 is about 2 mm, the actual dimension d of the second connecting portion 21 located in the vicinity of the central portion is about 1 mm, and the actual dimensions e of the other second connecting portions 21 are about 0.5 mm.

このようにして、展開図が形成される包装用箱Ｂは、図４示すようにして各折線にしたがって折曲させ、所定箇所を貼着することによって組み立てられる。 In this way, the packaging box B on which the development view is formed is assembled by bending according to each fold line as shown in FIG.

具体的には、右側板１、前側板２、左側板３、後側板４及び糊代片５を折線ａ、ｂ、ｃ、ｄに沿って折曲させ、糊代片５を右側板１に貼着し、４枚の外周壁からなる筒状体を構成する。次に、下内蓋６を折線ｅ、ｆに沿って折曲させるとともに、下方開口部を覆うように第１下蓋８を折線ｉに沿って折曲させる。そして、第２下蓋１１を折線ｊに沿って折曲させ、第１下蓋８を第２下蓋１１に貼着して、包装用箱Ｂの下方蓋を構成する。 Specifically, the right side plate 1, the front side plate 2, the left side plate 3, the rear side plate 4, and the glue margin piece 5 are bent along the fold lines a, b, c, d, and the glue margin piece 5 is attached to the right side plate 1. It sticks and comprises the cylindrical body which consists of four outer peripheral walls. Next, the lower inner lid 6 is bent along the folding lines e and f, and the first lower lid 8 is bent along the folding line i so as to cover the lower opening. And the 2nd lower cover 11 is bent along the fold line j, the 1st lower cover 8 is stuck on the 2nd lower cover 11, and the lower cover of the packaging box B is comprised.

また、上内蓋７を折線ｇ、ｈに沿って折曲させ、上方開口部を覆うように上蓋１２を折線ｋに沿って折曲させるとともに、差し込み片１３、摘み片１５及び貼着片１７を折線ｌに沿って折曲させ、貼着片１７を前側板２に貼着して、包装用箱Ｂの上方蓋を構成する。これにより、同図に示すような包装用箱Ｂが組み立てられる。包装用箱Ｂの上方蓋、下方蓋の形成順序は適宜とすることができ、収納物等は上方蓋、下方蓋を形成する前に収納される。 Further, the upper inner lid 7 is bent along the fold lines g and h, and the upper lid 12 is bent along the fold line k so as to cover the upper opening, and the insertion piece 13, the pick piece 15, and the sticking piece 17. Is folded along the folding line l, and the sticking piece 17 is stuck to the front side plate 2 to constitute the upper lid of the packaging box B. Thereby, the packaging box B as shown in the figure is assembled. The order of forming the upper lid and the lower lid of the packaging box B can be set appropriately, and the stored items and the like are stored before the upper lid and the lower lid are formed.

このようにして組み立てられる包装用箱Ｂにおける通常下での開封は、摘み片１５の端部を把持して、第１ミシン目部１４及び第２ミシン目部１６に沿って破断することで行われる。これにより、上蓋１２及び差し込み片１３が貼着片１７から分離され、上方蓋が開口した状態となり、収納物等を取り出すことができる。また、取り出した収納物等を再度収納する際には、差し込み片１３を上方開口部に差し込むことで繰り返して使用することができる。 The normal opening in the packaging box B assembled in this way is performed by gripping the end of the knob 15 and breaking along the first perforation 14 and the second perforation 16. Is called. Thereby, the upper lid 12 and the insertion piece 13 are separated from the sticking piece 17, the upper lid is opened, and the stored items and the like can be taken out. Moreover, when storing the taken-out storage thing etc. again, it can be used repeatedly by inserting the insertion piece 13 in an upper opening part.

そして、使用後における折り畳み方法については、次のようにして行われる。まず、前側板２の押切部９を押圧して、押切用破断線１０に沿って破断する。これにより、第１下蓋８が前側板２から分離されるとともに、第１下蓋８が第２下蓋１１に貼着されていることから、下方蓋が開口した状態となる。そして、４枚の外周壁からなる筒状体を扁平状に折り畳むことで、包装用箱Ｂを廃棄することができる。 And the folding method after use is performed as follows. First, the pressing part 9 of the front side plate 2 is pressed to be broken along the breaking line 10 for pressing. Thereby, while the 1st lower cover 8 is isolate | separated from the front side board 2, since the 1st lower cover 8 is stuck on the 2nd lower cover 11, it will be in the state which the lower cover opened. And the packaging box B can be discarded by folding the cylindrical body which consists of four outer peripheral walls into flat shape.

一方、医療機関等の緊急を要する通常下以外の状況での開封においては、上述の通常下での折り畳み方法の際に行われる下方蓋を開口することで、収納物を取り出すことができる。 On the other hand, when opening a medical institution or the like other than under normal circumstances requiring urgency, the stored item can be taken out by opening the lower lid that is formed during the above-described normal folding method.

そして、使用後における折り畳み方法については、次のようにして行われる。図５に示すように、まず、貼着片１７を押圧して、前側板２及び貼着片１７を撓ませ、第２ミシン目部１６に沿って破断する。これにより、上蓋１２、差し込み片１３及び摘み片１５が貼着片１７から分離され、上方蓋が開口した状態となる。このとき、摘み片１５の略中央部近郊に位置する第２ミシン目部１６における第２繋ぎ部２１の寸法ｄは、その他の第２繋ぎ部２１の寸法ｅより長く設定されている。よって、貼着片１７の略中央部を押圧し、第２繋ぎ部２１（寸法ｄ）に付加力を作用させることで、当該箇所を破断し隣接する第２切込部２０と連結させる。これにより、第２切込部２０の長さを倍増させることで、第２ミシン目部１６の破断を容易に行うことができる。そして、図６に示すように、４枚の外周壁からなる筒状体を扁平状に折り畳むことで、包装用箱Ｂを廃棄することができる。この際、廃棄される包装用箱Ｂ以外に不必要な廃棄対象物を出すことがないので、廃棄を主とした観点から鑑みれば有用なものとなる。 And the folding method after use is performed as follows. As shown in FIG. 5, first, the sticking piece 17 is pressed to bend the front side plate 2 and the sticking piece 17, and break along the second perforated portion 16. Thereby, the upper lid 12, the insertion piece 13, and the knob 15 are separated from the sticking piece 17, and the upper lid is opened. At this time, the dimension d of the second joint portion 21 in the second perforation 16 located near the center of the knob 15 is set longer than the dimension e of the other second joints 21. Therefore, the substantially center part of the sticking piece 17 is pressed and an additional force is applied to the second connecting part 21 (dimension d), whereby the part is broken and connected to the adjacent second cut part 20. Thereby, the 2nd perforation part 16 can be easily fractured by doubling the length of the second cut part 20. And as shown in FIG. 6, the packaging box B can be discarded by folding the cylindrical body which consists of four outer peripheral walls into flat shape. At this time, unnecessary disposal objects other than the packaging box B to be discarded are not put out, which is useful from the viewpoint of disposal.

以上、説明した本発明に係る包装用箱Ｂによれば、食品、飲料、医薬品等を収納した包装用箱Ｂを日常等の通常下の状況で使用する場合においては、特段問題とされることのない程度の廃棄対象物を出すことになるが、医療機関等の緊急を要する通常下以外の状況で使用する場合においては、廃棄対象物を出すことなく、容易に開封作業及び廃棄作業を行うことができる。 As described above, according to the packaging box B according to the present invention described above, when the packaging box B containing foods, beverages, medicines and the like is used in a normal situation such as daily life, it is regarded as a particular problem. However, when used in a non-normal situation that requires urgency, such as a medical institution, it is easy to open and dispose of the waste without releasing the waste. be able to.

更に、上述した組み立て順序により、折線ａからｌにしたがって各構成板及び構成片を折曲すればよいので、自動製函機（サックマシン）で作製できるものとなり、量産化がし易いものとなる。 Furthermore, according to the assembly sequence described above, each component plate and component piece may be bent according to the folding lines a to l, so that it can be manufactured by an automatic box making machine (sack machine), and mass production is easy. .

また、上記実施例に係る包装用箱Ｂにおいて、貼着片１７が貼着される前側板２に第３ミシン目部２４を設けた包装用箱Ｂ１とすることもできる。当該第３ミシン目部２４は、上記通常下以外の状況にて使用後に折り畳む際、前側板２及び貼着片１７を撓ませることで破断され、第２ミシン目部１６をより破断させ易くするために設けられる。 Moreover, in the packaging box B according to the above-described embodiment, the packaging box B1 may be a packaging box B1 in which the third perforation portion 24 is provided on the front plate 2 to which the sticking piece 17 is stuck. The third perforation portion 24 is broken by bending the front side plate 2 and the sticking piece 17 when folded after use in a situation other than the normal bottom, thereby making the second perforation portion 16 easier to break. Provided for.

すなわち、包装用箱Ｂ１が組み立てられた状態において、第３ミシン目部２４は、貼着片１７と貼着される前側板２における両者の重合領域内の前側板２に設けられる。そして、前側板２に貼着される貼着部１７を対向する後側板４側へ押圧することで、第３ミシン目部２４が破断するように機械的強度が設定されており、対向する側板側への前後方向の付加力によって破断されるものである。よって、第３ミシン目部２４の機械的強度は、第２ミシン目部１６の機械的強度より小さく設定される。また、第３ミシン目部２４においても、同様にして、開封手段として用いられる公知の形状を採用するものであり、特に限定されるものではないのは勿論である。 That is, in a state where the packaging box B1 is assembled, the third perforation portion 24 is provided on the front plate 2 in the overlapping region of both the sticking piece 17 and the front plate 2 to be stuck. And the mechanical strength is set so that the 3rd perforation part 24 may fracture | rupture by pressing the sticking part 17 stuck on the front side board 2 to the back side board 4 side which opposes. It is broken by the applied force in the front-rear direction to the side. Therefore, the mechanical strength of the third perforation portion 24 is set smaller than the mechanical strength of the second perforation portion 16. Similarly, the third perforation portion 24 adopts a known shape used as an opening means, and is not particularly limited.

例えば、第３ミシン目部２４は、図７及び図８に示すように、第３切込部２５と第３繋ぎ部２６が交互に連続することで構成され、第２ミシン目部１６と略平行な連結片を上方側に有する略コ字状に形成される。このとき、左右両端の縦線部２７を連結して横方向に延びる横線部２８は、第２ミシン目部１６と略重合する位置に設けることが望ましい。これにより、第２ミシン目部１６を破断させる際の付加力を第３ミシン目部２４に対しても十分に付与することができる。 For example, as shown in FIG. 7 and FIG. 8, the third perforation portion 24 is configured by the third cut portions 25 and the third joint portions 26 being alternately continuous, and is substantially the same as the second perforation portion 16. It is formed in a substantially U shape having parallel connecting pieces on the upper side. At this time, it is desirable that the horizontal line portion 28 extending in the horizontal direction by connecting the vertical line portions 27 at the left and right ends is provided at a position where the second perforation portion 16 is substantially overlapped. Thereby, the additional force at the time of breaking the 2nd perforation part 16 can fully be provided also to the 3rd perforation part 24. FIG.

ここで、略重合の技術的意義は、横線部２８と第２ミシン目部１６とが組み立て状態の前後方向に完全に重合するものに限られず、第２ミシン目部１６を破断させる際の付加力を第３ミシン目部２４に対して付与することができる範囲内において上下方向に離間するものをも含む趣旨である。また、横線部２８と第２ミシン目部１６の長さ寸法が一致しない場合をも含むのは勿論である。 Here, the technical significance of the approximate polymerization is not limited to the case where the horizontal line portion 28 and the second perforated portion 16 are completely polymerized in the front-rear direction of the assembled state, but is added when the second perforated portion 16 is broken. It is intended to include those that are separated in the vertical direction within a range in which a force can be applied to the third perforation 24. Of course, the case where the lengths of the horizontal line portion 28 and the second perforation portion 16 do not coincide with each other is also included.

また、第３ミシン目部２４を対向する側板側への前後方向に破断するとの観点から、横線部２８における第３切込部２５の個数は奇数倍を形成することが望ましい。更には、横線部２８における略中央部に位置する第３切込部２５を前側板２における幅方向（左右方向）の略中央部又はその近郊に位置させることが望ましい。 Further, from the viewpoint of breaking the third perforation portion 24 in the front-rear direction toward the opposing side plate, it is desirable that the number of the third cut portions 25 in the horizontal line portion 28 is an odd multiple. Furthermore, it is desirable that the third cut portion 25 located at a substantially central portion of the horizontal line portion 28 is located at a substantially central portion of the front side plate 2 in the width direction (left-right direction) or its vicinity.

ここで、同図における縦線部２７の実寸法をｆとし、横線部２８の実寸法をｇとする。また、横線部２８に連結される縦線部２７の第３切込部２５の実寸法をｈとし、縦線部２７の第３繋ぎ部２６の実寸法をｉとする。そして、横線部２８における略中央部に位置する第３切込部２５の実寸法をｊとし、その両端の第３繋ぎ部２６の実寸法をｋとする。 Here, the actual dimension of the vertical line portion 27 in the figure is f, and the actual dimension of the horizontal line portion 28 is g. In addition, the actual dimension of the third cut portion 25 of the vertical line portion 27 connected to the horizontal line portion 28 is h, and the actual dimension of the third joint portion 26 of the vertical line portion 27 is i. In addition, the actual dimension of the third cut portion 25 located substantially in the center of the horizontal line portion 28 is j, and the actual dimension of the third connecting portions 26 at both ends thereof is k.

このとき、例えば、縦線部２７の実寸法ｆを約１５ｍｍとし、横線部２８の実寸法ｇを約３０ｍｍとする。また、横線部２８に連結される縦線部２７の第３切込部２５の実寸法ｈを約３ｍｍとし、縦線部２７の第３繋ぎ部２６の実寸法ｉを約０．５〜０．７ｍｍとし、その余を縦線部２７の第３切込部２５とする。そして、横線部２８における略中央部に位置する第３切込部２５の実寸法ｊを約１０ｍｍとし、その両端の第３繋ぎ部２６の実寸法ｋを約０．５〜０．７ｍｍとし、その余を縦線部２７に連結される横線部２８の第３切込部２５とする。 At this time, for example, the actual dimension f of the vertical line portion 27 is about 15 mm, and the actual dimension g of the horizontal line portion 28 is about 30 mm. The actual dimension h of the third cut portion 25 of the vertical line portion 27 connected to the horizontal line portion 28 is about 3 mm, and the actual dimension i of the third joint portion 26 of the vertical line portion 27 is about 0.5 to 0. 7 mm, and the remainder is the third cut portion 25 of the vertical line portion 27. And the actual dimension j of the 3rd notch part 25 located in the approximate center part in the horizontal line part 28 shall be about 10 mm, the actual dimension k of the 3rd connection part 26 of the both ends shall be about 0.5-0.7 mm, The remainder is the third cut portion 25 of the horizontal line portion 28 connected to the vertical line portion 27.

このようにして展開図が形成される包装用箱Ｂ１は、各折線にしたがって折曲させ、所定箇所を貼着することによって組み立てられる。この点については、上記実施例と同様である。また、通常下での開封及び使用後における折り畳み方法についても、上記実施例と同様である。 The packaging box B1 in which the development view is formed in this way is assembled by bending according to each folding line and sticking a predetermined portion. About this point, it is the same as that of the said Example. Also, the opening method under normal conditions and the folding method after use are the same as in the above embodiment.

一方、医療機関等の緊急を要する通常下以外の状況での開封においては、上記実施例と同様であるが、使用後における折り畳み方法については、次のようにして行われる。図９に示すように、貼着片１７を押圧して、前側板２及び貼着片１７を撓ませ、第２ミシン目部１６及び第３ミシン目部２４に沿って破断する。これにより、上蓋１２、差し込み片１３及び摘み片１５が貼着片１７から分離され、上方蓋が開口した状態となる。 On the other hand, the opening in a situation other than the normal situation requiring emergency such as a medical institution is the same as in the above embodiment, but the folding method after use is performed as follows. As shown in FIG. 9, the sticking piece 17 is pressed to bend the front side plate 2 and the sticking piece 17, and break along the second perforated portion 16 and the third perforated portion 24. Thereby, the upper lid 12, the insertion piece 13, and the knob 15 are separated from the sticking piece 17, and the upper lid is opened.

このとき、第３ミシン目部２４の機械的強度は、貼着片１７を対向する後側板４側へ押圧することによる前後方向の付加力によって破断する第２ミシン目部１６の機械的強度より小さく設定されている。よって、前側板２及び貼着片１７を撓ませると、第２ミシン目部１６より先に第３ミシン目部２４が破断し、前側板２の一部が開口した状態となる。これにより、当該前側板２は、前後方向の付加力によって貼着片１７を介して後側板４側へ誘導されるので、貼着片１７のみを撓ませることで第２ミシン目部１６を破断させることができる。結果として、第３ミシン目部２４を設けない包装用箱Ｂと比較して、第２ミシン目部１６の破断をより容易に行うことができる。そして、４枚の外周壁からなる筒状体を扁平状に折り畳んで、包装用箱Ｂ１を廃棄することができる点についても、上記実施例と同様である。 At this time, the mechanical strength of the third perforation portion 24 is greater than the mechanical strength of the second perforation portion 16 that is broken by an additional force in the front-rear direction caused by pressing the sticking piece 17 toward the opposite rear plate 4 side. It is set small. Therefore, when the front side plate 2 and the sticking piece 17 are bent, the third perforation portion 24 is broken before the second perforation portion 16 and a part of the front side plate 2 is opened. Thereby, since the said front side board 2 is induced | guided | derived to the back side board 4 side via the sticking piece 17 by the additional force of the front-back direction, the 2nd perforation part 16 is fractured | ruptured by bending only the sticking piece 17. Can be made. As a result, the second perforation portion 16 can be more easily broken as compared with the packaging box B without the third perforation portion 24. And it is the same as that of the said Example also about the point which can fold the cylindrical body which consists of four outer peripheral walls into flat shape, and can discard packaging box B1.

上記包装用箱Ｂ１における略コ字状の第３ミシン目部２４の第３切込部２５、第３繋ぎ部２６については、第３ミシン目部２４が破断され易いよう適宜の位置に設けることができるのは勿論である。例えば、左右の縦線部２７においては、いずれか一方の縦線部２７のみに第３繋ぎ部２６を設けることもできるし、第３繋ぎ部２６の位置を左右の縦線部２７で夫々異なるように設けることもできる。 The third cut portion 25 and the third joint portion 26 of the substantially U-shaped third perforation portion 24 in the packaging box B1 are provided at appropriate positions so that the third perforation portion 24 is easily broken. Of course you can. For example, in the left and right vertical line portions 27, the third connecting portion 26 can be provided only in one of the vertical line portions 27, and the position of the third connecting portion 26 is different between the left and right vertical line portions 27. It can also be provided.

また、左右の縦線部２７を第３切込部２５のみから形成し、横線部２８を第３切込部２５及び第３繋ぎ部２６から形成することもできる。更に、左右の縦線部２７を第３切込部２５及び第３繋ぎ部２６から形成し、横線部２８を第３切込部２５のみから形成することもできる。 Alternatively, the left and right vertical line portions 27 may be formed only from the third cut portions 25, and the horizontal line portion 28 may be formed from the third cut portions 25 and the third connecting portions 26. Furthermore, the left and right vertical line portions 27 can be formed from the third cut portions 25 and the third connecting portions 26, and the horizontal line portions 28 can be formed only from the third cut portions 25.

更には、包装用箱Ｂ１における第３ミシン目部２４の形状は、略コ字状に限られるものではなく、第２ミシン目部１６と略平行な横線部２８を少なくとも有するものとすることもできるし、上方側に屈曲部を有する略ヘ字状とすることもできるし、特に限定されるものではない。 Furthermore, the shape of the third perforation portion 24 in the packaging box B1 is not limited to a substantially U-shape, and may include at least a horizontal line portion 28 substantially parallel to the second perforation portion 16. It can also be made into a substantially square shape having a bent portion on the upper side, and is not particularly limited.

すなわち、第３ミシン目部２４が破断された後、前後方向の付加力によって貼着片１７を介して前側板２を後側板４側へ誘導させることができるような形状であればよい趣旨である。より詳細には、第２ミシン目部１６側に指の先端を向けて配置して前側板２及び貼着片１７を撓ませる際、前後方向の付加力に関与する当該指の形状を考慮して、第３ミシン目部２４が形成されてあればよい趣旨である。 In other words, after the third perforation portion 24 is broken, the shape may be any shape as long as the front side plate 2 can be guided to the rear side plate 4 side through the sticking piece 17 by the applied force in the front-rear direction. is there. More specifically, when the front side plate 2 and the sticking piece 17 are bent with the tip of the finger facing the second perforation 16 side, the shape of the finger involved in the applied force in the front-rear direction is taken into consideration. In other words, the third perforation 24 should be formed.

また、いずれの包装用箱Ｂ、Ｂ１においても、糊代片５は、後側板４以外の右側板１、前側板２、左側板３に設けることもできるし、押切部９は、前側板２以外の右側板１、左側板３、後側板４に設けることもできる。 Further, in any of the packaging boxes B and B1, the adhesive margin piece 5 can be provided on the right side plate 1, the front side plate 2 and the left side plate 3 other than the rear side plate 4, and the pressing part 9 is provided on the front side plate 2. Other than the right side plate 1, the left side plate 3, and the rear side plate 4 can also be provided.

その他、形状、寸法、材質等を適宜変更して実施することが可能である。また、一部構成を省略することができるし、一部抽出した構成とすることができるのは勿論である。 In addition, the shape, dimensions, material, and the like can be changed as appropriate. Of course, a part of the configuration can be omitted, and a part of the configuration can be extracted.
