Description

この発明は、段ボール等の剛性が比較的欠けるような素材により組み立てられる箱であって、液体や粉粒体を漏れなく包装するためにフィルム製の内袋を備えた流体の包装箱に関する。   The present invention relates to a fluid packaging box having an inner bag made of a film for packaging liquids and granular materials without leakage, which is a box assembled from a material such as corrugated cardboard, which is relatively lacking in rigidity.

段ボールや厚紙等で組み立てた箱で、例えば、インク、塗料、化学薬品その他原料等を包装するために、それを漏れなく密閉する内袋を備えたものが、他の一斗缶等の容器よりも安価であるばかりでなく、軽量で取り扱いやすく、また、折畳み可能な組立て形態によって反復使用に好都合であり、さらに、使用済みの際に廃棄処分も容易である等の利点を有する。しかし、内容物の圧力により箱に胴脹れが生じるという難点があり、輸送の安全性からその防止について工夫される。   A box assembled with cardboard, cardboard, etc., for example, with an inner bag that seals it without leakage in order to wrap ink, paint, chemicals and other raw materials. In addition to being inexpensive, it is advantageous in that it is lightweight and easy to handle, is convenient for repeated use due to its foldable assembly form, and is easy to dispose of when used. However, there is a problem that the box is swollen by the pressure of the contents, and the prevention is devised for the safety of transportation.

従来、このような胴脹れ防止は、内袋の胴脹れを阻止するものであって、これには、段ボール箱の四隅角に内袋の膨出を止める補強材を入れる方法が取られていた。   Conventionally, such a swelling prevention prevents the inner bag from being swollen, and a method of putting a reinforcing material for preventing the inner bag from bulging at the four corners of the cardboard box is used. It was.

上記のように補強材を入れる方法によれば、それには段ボールを折り曲げることにより三角形の角筒形に形成した部材が用いられるが、これによると、それだけ部材を多用してコスト高となるだけでなく軽量化に適しなく、また、補強材が箱の折畳みの障害になる等の問題があった。   According to the method of inserting a reinforcing material as described above, a member formed into a triangular prismatic tube shape by bending a corrugated cardboard is used for this, but according to this, only a lot of members are used and the cost is increased. This is not suitable for weight reduction, and there is a problem that the reinforcing material becomes an obstacle to folding the box.

この発明は、上記のような実情に鑑みて、部材を多用しないのでコスト的に安価となるとともに軽量化に適し、また、内袋を内装したままの折畳みが可能であり、しかも、箱の膨出を確実に防止できる流体の包装箱を提供することを課題とした。   In view of the above situation, the present invention does not use many members, so that the cost is low and it is suitable for weight reduction. Further, the inner bag can be folded and the box is inflated. It was an object to provide a fluid packaging box that can reliably prevent ejection.

上記の課題を解決するために、この発明は、上下フラップを備えた外箱と、その折畳みにおいて偏平となるよう内装される内袋とからなり、外箱と内袋との間に内袋を折畳みの開閉に順応が可能に常時保持する支持手段を備えた流体の包装箱において、内袋は、内袋としての幅が外箱の隣接する両側壁の合計幅よりも少ない幅であるとともに、膨出した円形状としては各側壁に近接する胴回りとなる大きさであることを特徴とする流体の包装箱を提供するものである。   In order to solve the above problems, the present invention comprises an outer box having upper and lower flaps and an inner bag that is internally flattened when folded, and the inner bag is provided between the outer box and the inner bag. In the fluid packaging box provided with a support means that always holds so that it can adapt to the folding opening and closing, the inner bag has a width that is smaller than the total width of both side walls adjacent to the outer box, The bulging circular shape provides a fluid packaging box characterized in that it has a size that becomes a waist around each side wall.

上記において、包装箱の形式としては、A式,B式(差込み式)などが有り、箱の材質としては、紙製段ボール,プラスチック製段ボール,紙のボード,プラスチック製のボードなどが有り得る。また、内袋の形式としては、平袋,幅ガゼット袋,底ガゼット袋等が有り、内袋の材質としては、PE,NY/PE,PET/NY/AL/LL等の材質で、単層フィルム,共押し出しフィルム,ラミネートフィルム等で構成されているものを挙げることができる。なお、以下は便宜上、外箱がA式、内袋が平袋である場合を主体として説明して行く。   In the above, there are A-type and B-type (insertion type) as the packaging box type, and the box material may be paper cardboard, plastic cardboard, paper board, plastic board and the like. In addition, there are flat bags, width gusset bags, bottom gusset bags, etc. as inner bag types, and the inner bag material is made of PE, NY / PE, PET / NY / AL / LL, etc., single layer Examples include a film, a coextruded film, a laminate film, and the like. In the following, for the sake of convenience, the case where the outer box is an A type and the inner bag is a flat bag will be mainly described.

流体の包装箱を上記のように構成したから、支持手段で外箱に保持されながら折畳みの開閉に内袋が順応して変形を繰り返すものであるが、外箱を組立て開いてそれに内容物を充填して包装したとき、内袋が円形状に膨出しているが、外箱に対する内袋の胴回りの大きさが限定されているので、その円形状が外箱の内面に間隔をおいて近接しているか、接触していてもその圧力がわずかであるから、外箱は内容物の圧力により胴脹れすることはない。   Since the fluid packaging box is configured as described above, the inner bag adapts to opening and closing of the fold while being held in the outer box by the supporting means, and the deformation is repeated. When filled and packaged, the inner bag swells in a circular shape, but because the size of the inner bag's circumference around the outer box is limited, the circular shape is close to the inner surface of the outer box with a gap The outer box is not swollen by the pressure of the contents because the pressure is slight even if it is in contact or in contact.

なお、内袋について、「膨出した円形状としては各側壁に近接する胴回りとなる大きさ」とは、使用する内袋について、仮に(空気等の軽い注入で)胴回りが円形に膨出したならば、各側壁に近接(内容物の圧力で膨出して接触する場合も含む)するサイズの平袋が使用されることを意味するものとする。したがって、後記するように、実際には異形円として膨出することもある。   As for the inner bag, “the size of the swollen circular shape that is close to each side wall” means that the inner swirl of the inner bag used was swollen in a circular shape (by light injection of air or the like). Then, it means that a flat bag having a size close to each side wall (including a case where it swells and contacts with the pressure of the contents) is used. Therefore, as will be described later, it may actually swell as a deformed circle.

また、この発明の目的を達成できるものであれば、支持手段は特に限定するものではないが、請求項2ないし請求項8に記載した場合には、一層確実に目的を達成することができる。   Further, the supporting means is not particularly limited as long as the object of the present invention can be achieved, but the object can be achieved more reliably in the cases described in claims 2 to 8.

以上説明したように、この発明の流体の包装箱によれば、部材を多用しないので、コスト的に安価であり軽量化に適することはもちろん、妨げの部材がないことから内袋を内装したままの折畳みの開閉が可能であり、しかも、箱の膨出を確実に防止できるために、粉粒体の輸送における経済性や安全性を確保し、あわせて作業性を向上させる上で優れた効果を奏する。   As described above, according to the fluid packaging box of the present invention, since many members are not used, it is inexpensive and suitable for weight reduction. It is possible to open and close the folds and reliably prevent the box from bulging, thus ensuring economic and safety in transporting the granular material, and at the same time, improving the workability. Play.

次に、この発明の実施形態を図面に基づいて説明する。   Next, embodiments of the present invention will be described with reference to the drawings.

図1ないし図6は一実施の形態について示したもので、その流体の包装箱Paは、段ボールで組み立てられるA式の外箱1と、それに納まる内袋2とからなり、上端に液体の注出入口3を有し、それが段ボール箱1に対する内袋2の支持手段ともなっている。つまり、内袋2が注出入口3を介して外箱1に結合しているために、それだけで常時吊り下げ状態となっている。しかし、必要があれば後記するように別途に粘着部分を設けて結合をさらに安定化させることもできる。   FIG. 1 to FIG. 6 show an embodiment, and the fluid packaging box Pa is composed of an A-type outer box 1 assembled with cardboard and an inner bag 2 accommodated in the A-type outer box 1, and liquid is poured into the upper end. An entrance / exit 3 is provided, which also serves as a support means for the inner bag 2 with respect to the cardboard box 1. That is, since the inner bag 2 is coupled to the outer box 1 through the pouring inlet 3, it is always suspended. However, if necessary, the bonding can be further stabilized by providing a separate adhesive portion as will be described later.

外箱1は、それぞれほゞ正四角形の前後両側壁5,5と左右両側壁7,7とが交互となる端に糊代9を連設して構成され、前後両側壁5,5の上下両端に内フラップ11,11を、左右両側壁7,7の上下両端に外フラップ13,13がそれぞれ連設されるが、上端前側の内フラップ11において注出入口3を取り付ける窪壁15が形成される。   The outer box 1 is formed by connecting adhesive margins 9 at the ends where the front and rear side walls 5 and 5 and the left and right side walls 7 and 7 of a substantially square shape are alternately arranged. Inner flaps 11, 11 are connected to both ends, and outer flaps 13, 13 are connected to upper and lower ends of the left and right side walls 7, 7 respectively, but a recessed wall 15 is formed in the inner flap 11 on the front side of the upper end. The

窪壁15の形成については、その内フラップ11に幅中央部においてその先端部近くで反転するU字形の切溝16を設けるとともに、その両端を前側壁5に少し段落させるように延長して形成し、両延長終点の間に折れ線17が設けられ、窪壁15の中央部に注出入口3の取付孔19が穿設される。   The recessed wall 15 is formed by providing the inner flap 11 with a U-shaped kerf 16 that inverts near the tip at the center of the width, and extending both ends of the inner wall 11 so that the front side wall 5 is slightly separated. A broken line 17 is provided between the extension end points, and a mounting hole 19 for the pouring inlet 3 is formed in the central portion of the recessed wall 15.

内袋2は、プラスチックフィルムのチューブを切断してなるもので、その上下両端に二つ合わせに接着してシール部21,21を有する偏平な平袋を原型とする(図1二点鎖線)。そして、同図に示すように、その平形の幅Lで前側壁5とその隣接一側壁7との双方に均等に(2Wの中央部に)配置され、その位置を保持するように注出入口3が前記内フラップ11に結合している。   The inner bag 2 is formed by cutting a plastic film tube, and a flat flat bag having seal portions 21 and 21 bonded to both upper and lower ends is used as a prototype (FIG. 1, two-dot chain line). . And, as shown in the figure, the spout inlet 3 is arranged so as to be evenly (at the center of 2W) with both the front side wall 5 and the adjacent one side wall 7 with the flat width L, and to keep the position. Is connected to the inner flap 11.

注出入口3は、蓋3aとともにプラスチック製であって、下端に鍔部23が突設され(図5)、蓋3aを螺着するねじ部の下端に環状の逆止爪25が形成されているので、窪壁15の取付孔19に下から嵌入させ、その操作で孔19の周縁部が鍔部23と逆止爪25で挟ませてある。この場合に、予め内袋2の開口孔27の周縁部27aが取付孔19の周縁部下面に接着されているので、内袋2もこの部分27aで同時に挟まれて外箱1に対する取付けが確実となっている。   The inlet / outlet 3 is made of plastic together with the lid 3a, and has a flange 23 protruding at the lower end (FIG. 5), and an annular check claw 25 is formed at the lower end of the screw portion to which the lid 3a is screwed. Therefore, it is inserted into the mounting hole 19 of the recessed wall 15 from below, and the peripheral portion of the hole 19 is sandwiched between the flange portion 23 and the check claw 25 by the operation. In this case, since the peripheral edge portion 27a of the opening hole 27 of the inner bag 2 is bonded in advance to the lower surface of the peripheral edge portion of the mounting hole 19, the inner bag 2 is also sandwiched by this portion 27a at the same time and is securely attached to the outer box 1. It has become.

図3及び図4は、内袋2に液体を充填した包装状態を示したもので、この場合は、内袋2の胴部外周が円形において各側壁5,5,7,7に空間を隔てて近接している。したがって、この状態では余裕が十分にあるために外箱1は決して膨出しなく、内接状態であっても膨出しない。なお、実際にはこのように均等な形状や位置にならないが説明の都合から分かりやすく図示した。それでは、各側壁5,7に内袋2の膨出円が内接するときにおいて、側壁5,7の幅Wと、内袋2の平袋幅Lとの相互の関係を見ることにする。   3 and 4 show a packaging state in which the inner bag 2 is filled with a liquid. In this case, the outer periphery of the body portion of the inner bag 2 is circular, and spaces are separated from the side walls 5, 5, 7, and 7. Are close to each other. Accordingly, since there is a sufficient margin in this state, the outer box 1 never bulges, and does not bulge even in the inscribed state. Actually, the shape and position are not uniform in this way, but are shown in an easy-to-understand manner for convenience of explanation. The relationship between the width W of the side walls 5 and 7 and the flat bag width L of the inner bag 2 when the bulging circle of the inner bag 2 is inscribed in the side walls 5 and 7 will be seen.

図6に従い、内袋2の平袋幅Lを求めてみると、それは内袋2の内接円の円周の長さの2分の1であるから、2πW×0.5という式が成り立ち(πは円周率)、使用する内袋2のサイズについては、それからL<1.57Wとなりこれが目安となる。つまり、図1に示すように、平袋幅Lは隣接する2側壁5,7を合わせた2Wの幅の中に余裕をもって納まることになる。そして、種々の実験結果から、内袋2が内接円(図6)より小さい場合に、外箱1の膨出を安全確実に防止し得ることが分かった。この実施形態であると、内袋2が円(仮には図示の如く真円)として膨出する場合であるが、後記する実施形態の場合におけるように、異なる特殊な支持手段のために、異形円に膨出する場合にも同じ結果となることも分かった。したがって、上記の如く請求項1の通り内袋2の大きさを特定した。なお、以上の説明は、以下の各実施形態においても同じであるので、同符号を付して以下には説明を省略する。   According to FIG. 6, when the flat bag width L of the inner bag 2 is obtained, it is a half of the circumference of the inscribed circle of the inner bag 2, and therefore the formula 2πW × 0.5 holds. (Π is the circumference), and the size of the inner bag 2 to be used is then L <1.57W, which is a guide. That is, as shown in FIG. 1, the flat bag width L is accommodated in a 2 W width including the two adjacent side walls 5 and 7 with a margin. From various experimental results, it has been found that when the inner bag 2 is smaller than the inscribed circle (FIG. 6), the bulging of the outer box 1 can be safely and reliably prevented. In this embodiment, the inner bag 2 bulges out as a circle (assuming a perfect circle as shown in the figure). However, as in the case of the embodiment described later, because of different special support means, It was also found that the same result was obtained when bulging into a circle. Therefore, the size of the inner bag 2 was specified as described in claim 1 as described above. In addition, since the above description is the same also in each following embodiment, it attaches | subjects the same code | symbol and abbreviate | omits description below.

図7および図8は、注出入口3の他に別途支持手段を設けたために、内袋2が異形円となった場合の一例を示したもので、その流体の包装箱Pbは、前後両側壁5,5の内面に、幅中央部において、上下一対の粘着面32,32を設け、そこで内袋2を接着した。したがって、内袋2は、使用状態(図8)では真円の膨出が抑制され、空間を有する左右両側壁7,7側へ(X,X方向へ)膨出する力が前後両側壁5,5を内側へ(Y,Y方向へ)引く力として作用することになるために、前後両側壁5,5が膨出しないことはもとより、左右両側壁7,7も内袋2との接触がないために膨出しない。なお、上下の粘着面32,32は上下に連続していても良い。   7 and 8 show an example in which the inner bag 2 has a deformed circle because a separate supporting means is provided in addition to the pouring inlet 3, and the fluid packaging box Pb has both front and rear side walls. A pair of upper and lower adhesive surfaces 32, 32 were provided on the inner surfaces of 5, 5 at the width center, and the inner bag 2 was bonded thereto. Therefore, in the use state (FIG. 8), the inner bag 2 is restrained from bulging out of a perfect circle, and the force that bulges toward the left and right side walls 7 and 7 having the space (in the X and X directions) , 5 acts as a force pulling inward (Y, Y direction), so that the front and rear side walls 5, 5 do not bulge, and the left and right side walls 7, 7 are also in contact with the inner bag 2. Does not bulge because there is no. Note that the upper and lower adhesive surfaces 32, 32 may be continuous vertically.

図9および図10は、流体のうちでも主に粉粒体を包装するために、注出入口(3)を有しない流体の包装箱Pcを示したもので、外箱1は、前後両側壁5,5が丁度二つ合わせとなる折畳みとなるように、左右両側壁7,7にその上下外フラップ13,13にかけて幅中央に沿った中折れ線31,31が形成され、前後両側壁5,5の上下内フラップ11,11には、先端縁を直径とする半円の粘着面33,33が設けられる。   FIG. 9 and FIG. 10 show a packaging box Pc of fluid that does not have a pouring inlet (3) in order to wrap mainly powder particles among fluids. , 5 are formed in the left and right side walls 7, 7 so as to be folded together so that the middle folding lines 31, 31 along the width center are formed on the upper and lower outer flaps 13, 13. The upper and lower inner flaps 11 and 11 are provided with semicircular adhesive surfaces 33 and 33 each having a tip edge as a diameter.

内袋2は、同じく平袋であるが、下端のみにシール部21を設け上端が開放されたものが使用され、それが両中折れ線31,31の間(2Wの幅に相当する)の幅中央に配置して粘着面33,33に接着され、外箱1の折畳みの開閉に順応するようになっている。   The inner bag 2 is also a flat bag, but a seal portion 21 is provided only at the lower end and the upper end is opened, which is the width between the two bent lines 31, 31 (corresponding to a width of 2 W). It arrange | positions in the center and is adhere | attached on the adhesion surfaces 33 and 33, and adapts to opening and closing of folding of the outer case 1. As shown in FIG.

外箱1を組み立ててから内袋2に上端から内容物を投入するが、投入後は内袋2の上端21aを接着でシールし、密封してから上端の内フラップ11,11および外フラップ13,13を閉じる。そうすると、上端では(下端では既に)半円の粘着面33,33が合わさって円形となって内袋2を円形の胴長に保持しながら上下に突っ張ることになり、突っ張りでも内袋2が膨出することが阻止されるので、内袋2が外箱1の内面に未接触ないし弱接触の状態が保持されることになる。   After the outer box 1 is assembled, the contents are put into the inner bag 2 from the upper end. After the charging, the upper end 21a of the inner bag 2 is sealed with adhesive and sealed, and then the inner flaps 11 and 11 and the outer flap 13 at the upper end are sealed. , 13 is closed. Then, at the upper end (already at the lower end), the semicircular adhesive surfaces 33, 33 are combined to form a circle, and the inner bag 2 is stretched up and down while holding the circular trunk length. Since it is prevented from being taken out, the inner bag 2 is kept in a non-contact or weak contact state with the inner surface of the outer box 1.

図11および図12は、同じく外箱1が中折れ線31,31で折畳み可能となっており、また、内袋2も同じように配置されるが、上端では内フラップ11,11と外フラップ13,13とが入れ違いとなっており、前後両側壁5,5の上端に外フラップ13,13を設け、それに粘着面34,34が設けられる。そして、左右両側壁7,7の上端の内フラップ11,11の両側を切り欠いてその開閉線を底辺とする二等辺三角形に形成した。したがって、その内フラップ11,11を閉じると、切欠35,35から内袋2の上端が食み出ることになるので、その食み出た部分に外フラップ13,13が粘着される。これには内フラップ11,11との絡みがあるために、内袋2が上端では単なる粘着では得られない非常に強力な結合状態が得られる。また、この場合も、下端では内フラップ11,11に粘着面34,34が設けられ、こうして内袋2の上下突っ張りが強力に保持されるようになっている。   11 and 12, the outer box 1 can be folded along the middle folding lines 31 and 31, and the inner bag 2 is arranged in the same manner, but the inner flaps 11 and 11 and the outer flap 13 are arranged at the upper end. , 13 are misplaced, and outer flaps 13, 13 are provided at the upper ends of the front and rear side walls 5, 5, and adhesive surfaces 34, 34 are provided thereon. And it formed in the isosceles triangle which notched the both sides of the inner flaps 11 and 11 of the upper end of the right-and-left both-side walls 7 and 7, and made the opening-and-closing line the bottom. Accordingly, when the inner flaps 11 and 11 are closed, the upper end of the inner bag 2 is eroded from the notches 35 and 35, and the outer flaps 13 and 13 are adhered to the bulged portions. Since this has an entanglement with the inner flaps 11 and 11, a very strong bonded state that cannot be obtained by simple adhesion is obtained at the upper end of the inner bag 2. Also in this case, the adhesive surfaces 34, 34 are provided on the inner flaps 11, 11 at the lower end, so that the vertical tension of the inner bag 2 is strongly held.

図13及び図14は、さらに別の実施形態を示す、流体の包装箱の展開図と、その使用状態を示す斜視図である。この例では、内袋2がガゼット袋、特に幅ガゼットタイプの袋であり、図13はその幅ガゼット袋の一面を開いて示した実施例展開図である。   FIG.13 and FIG.14 is the expanded view of the fluid packaging box which shows another embodiment, and the perspective view which shows the use condition. In this example, the inner bag 2 is a gusset bag, in particular, a width gusset type bag, and FIG. 13 is a development view of an embodiment in which one side of the width gusset bag is opened.

このようなケースは、外箱が縦長の1斗缶タイプであり、注出入口3は、幅ガゼット袋2の隣接する側面の一隅角に設けられ、注出入口3を有する側面40と、その隣接する側面とがそれぞれ外箱の隣接する側面41に接着される。図13にはそのための接合部32,32,32,32が外箱の隣接する側面に設けられている。即ち、前記実施例とは異なり、接着の構成が、外箱側面の相対面どうしではなく、隣接側面40,41どうしであるという点である。なお、図13に示すように、幅ガゼット袋2の一面を開いた状態で外箱と接着したその幅Lは、2Wとの関係では、L<2Wとなっている。   In such a case, the outer case is a vertically long one-can type, and the pouring inlet 3 is provided at one corner of the adjacent side face of the width gusset bag 2, and the side face 40 having the pouring inlet 3 is adjacent to the side face 40. The side surfaces are respectively bonded to the adjacent side surfaces 41 of the outer box. In FIG. 13, joint portions 32, 32, 32, 32 for that purpose are provided on adjacent side surfaces of the outer box. That is, unlike the above-described embodiment, the bonding structure is not the relative surfaces of the outer box side surfaces but the adjacent side surfaces 40 and 41. As shown in FIG. 13, the width L of the width gusset bag 2 bonded to the outer box with one surface opened is L <2W in relation to 2W.

実際に外箱が組立てられ、注出入口3より流体が注入されると、図14に示すように、注出入口3側より対角線状に幅ガゼット袋2が膨らむ。即ち、内容物を入れることで内袋が広がり、全体として注出入口3方向に寄った円柱形が形成される。また、L<2Wの関係に構成されているので、幅ガゼット袋2の膨れがあっても、外箱の側面への影響はほとんど見られない。   When the outer box is actually assembled and fluid is injected from the outlet 3, the width gusset bag 2 swells diagonally from the outlet 3 side as shown in FIG.
