Description
本発明は梱包用の袋に関する。さらに詳しくは、複数個の商品などを梱包するための、段ボール箱に代えて用いられる梱包用の袋に関する。 The present invention relates to a packaging bag. More specifically, the present invention relates to a packing bag used in place of a cardboard box for packing a plurality of products.
トイレットペーパなどの商品は、通常は買い物客が持ち帰りやすいように、１２〜１８ロール程度を１パックに包装して店頭で販売される。そのときの包装材は透明なポリエチレンなどの合成樹脂製の袋が使用され、上端に手で提げるための持ち手が設けられる。他方、工場から問屋などを経由してトラックで運搬される流通段階では、それらのワンパック包装を段ボール箱に複数パック収容して運搬する。それにより倉庫やトラックの荷台に多段で積み重ねても安全に保管・収納することができる。 Products such as toilet paper are usually sold in stores with 12 to 18 rolls wrapped in one pack so that shoppers can easily take it home. At that time, a bag made of a synthetic resin such as transparent polyethylene is used as the packaging material, and a handle is provided at the upper end to be held by hand. On the other hand, in the distribution stage where the goods are transported by truck from a factory via a wholesaler or the like, a plurality of these one-pack packages are accommodated in a cardboard box and transported. As a result, it can be safely stored and stored even when stacked in multiple stages on a warehouse or truck bed.
他方、米、小麦粉、肥料などの粉体ないし粒状体は５〜２０ｋｇ程度をクラフト紙の紙袋に充填して搬送・保管される。このような紙袋は、たとえば特許文献１に開示されているように紙を筒状に形成したものを所定の長さに切断し、一方の開口部を折り畳み、糊などで封緘して底面とすることにより製造する。そして他方の開口部には、充填用のバルブ口を設けた上で、同じく折り畳んで糊などで封緘して上面とする。このような紙袋を用いた包装体は内容物を充填しているので積み重ねることができる。 On the other hand, about 5 to 20 kg of powder or granular material such as rice, wheat flour, and fertilizer is packed and transported and stored in a kraft paper bag. In such a paper bag, for example, as disclosed in Patent Document 1, a paper formed into a cylindrical shape is cut into a predetermined length, and one opening is folded and sealed with glue or the like to form a bottom surface. By manufacturing. The other opening is provided with a valve opening for filling, and is also folded and sealed with glue or the like to form the upper surface. Since the package using such a paper bag is filled with the contents, it can be stacked.
すなわち積み上げた包装体の上側の重量は下側の包装体の内容物で支持され、紙袋自体は内容物がばらけないように緊縛する働きをするだけである。それにより紙袋は内容物の重量をほとんど支持せず、破れるおそれはない。なお、これらの紙袋では上面にバルブ口が設けられているので、底面側に開封用のテープを設けており、開封する場合は底面側を上にして開封用テープを引っ張り、底面を引き裂く。また上記の粉体を充填した包装体の場合でも、複数個の包装体をまとめて梱包する場合は通常は段ボール箱に収容する。そのほうが安定するのでフォークリフトなどの搬送機械で運ぶ場合に都合がよい。 That is, the upper weight of the stacked package is supported by the contents of the lower package, and the paper bag itself only functions to bind the contents so that the contents are not scattered. As a result, the paper bag hardly supports the weight of the contents and does not break. Since these paper bags are provided with a valve opening on the upper surface, an opening tape is provided on the bottom surface side, and when opening, the opening tape is pulled up with the bottom surface side up, and the bottom surface is torn. Even in the case of a package filled with the above powder, when a plurality of packages are packed together, they are usually stored in a cardboard box. Since this is more stable, it is convenient when transporting with a transport machine such as a forklift.
特許文献２は、１６ロールなどのトイレットペーパを１パックとした包装製品をさらに複数パックを梱包して工場から出荷する場合に、段ボールに代えて紙袋を用いる方法を開示している。さらに紙袋を横向きに配置して複数パックを同時に紙袋に収納する方法、およびその方法を適用した自動包装ラインを開示している。 Patent Document 2 discloses a method in which a paper bag is used instead of cardboard when packaging a plurality of packs of 16-roll toilet products such as 16-roll toilet paper. Furthermore, a paper bag is disposed horizontally and a plurality of packs are simultaneously stored in the paper bag, and an automatic packaging line to which the method is applied is disclosed.
上記のように複数個の商品をまとめて梱包する場合は、消費者が持ち帰るワンパック包装を別にすれば、通常は段ボール箱が用いられる。しかし段ボール箱は紙袋に比して高価であり、厚さも数ミリメートルあるので、嵩高くなる。すなわちトラックの荷台に５〜１０段程度積み上げる場合、梱包材料である段ボールによって数センチ分、積載空間が占められることになる。 When a plurality of commodities are packed together as described above, a cardboard box is usually used, except for one-pack packaging that consumers bring home. However, a cardboard box is more expensive than a paper bag and has a thickness of several millimeters, which makes it bulky. That is, when stacking about 5 to 10 levels on the truck bed, the loading space is occupied by several centimeters by the corrugated cardboard as the packing material.
特許文献２の紙袋を梱包材料として使用する方法は、積み重ねたときに占める空間がかなり削減できる利点がある。ただし積み重ねができるようにするには、粉体の場合と同様に内容物で重量を支持できるように密に詰める必要がある。そして開口部は通常は折り畳んで梱包用の粘着テープで封緘するが、開封作業が煩雑であり、開口部からの内容物の取り出しが困難である。 The method of using the paper bag of Patent Document 2 as a packaging material has an advantage that the space occupied when stacked is considerably reduced. However, in order to be able to stack, it is necessary to pack closely so that the weight can be supported by the contents as in the case of powder. The opening is usually folded and sealed with an adhesive tape for packing, but the opening operation is complicated and it is difficult to take out the contents from the opening.
すなわち開梱時には、一端開口部が上向きになるように梱包体を置き直し、粘着テープを外して上部の開口から内容物を取り出す。しかし下部の内容物は袋に密に詰まっているので、取り出しが困難であり、たとえば上下を逆にして、下方の内容物を開口部側に落とすことになる。そのため、梱包体を何度も向きを変える必要がある。なお、上部の開口から側面まで引き裂いて、内容物を取り出すこともできるが面倒である。 That is, at the time of unpacking, the packing body is repositioned so that the opening at one end faces upward, the adhesive tape is removed, and the contents are taken out from the opening at the top. However, since the lower contents are tightly packed in the bag, it is difficult to take out the contents, and for example, the lower contents are dropped to the opening side upside down. Therefore, it is necessary to change the direction of the package many times. The contents can be taken out by tearing from the upper opening to the side surface, but is troublesome.
本発明は、合成樹脂袋あるいは紙袋と同程度に安価で、スペースをとらず、とくに開梱および内容物の取り出しが容易な梱包用の袋および梱包体を提供することを技術課題としている。 An object of the present invention is to provide a packaging bag and a packaging body that are as inexpensive as a synthetic resin bag or a paper bag, do not take up space, and are particularly easy to unpack and take out contents.
本発明の梱包用の袋は、内部に被梱包物を整列状態で密に収納するための、複数の層のシートを重ねてなる、有底筒状の紙製の梱包用の袋であって、その筒状の一方の開口部が折り畳まれ、アウターパッチが貼り付けられ、底面とされ、その底面および側面がそれぞれ矩形状であり、上端近辺に、開口部を折り畳んで封緘し、底面と同形の上面とする部分を備え、前記底面を下向きにした梱包状態で、高さの寸法が幅よりも大きく、４つの側面の内、面積が広い側面に、底面および上面となる範囲を除き、ミシン目または切れ目からなる、指を入れることができる幅の２本の平行な破断線が左右方向の中央部で縦方向に形成され、その２本の破断線の長さ方向の中間部に、その２本の破断線を横切る横向きの弱め線ないし切り離し部からなる開封線が設けられ、前記縦向きの２本の破断線が、複数の層の上層から下層まで達するように、側面の上下の端縁付近まで形成され、前記各層同士を２本の平行な破断線の間の部分で糊付けしていることを特徴としている（請求項１）。 The packing bag of the present invention is a bottomed cylindrical paper packing bag in which a plurality of layers of sheets are stacked in order to tightly store the objects to be packed in an aligned state. The cylindrical opening is folded, the outer patch is applied, and it is the bottom, the bottom and sides are each rectangular, and the opening is folded and sealed in the vicinity of the upper end. In a packaged state with the bottom surface facing downward , the height dimension is larger than the width, and the four side surfaces have a wide area, except for the range of the bottom surface and the top surface. Two parallel break lines , each having a width that can be inserted into a finger, are formed in the vertical direction at the center in the left-right direction, and are formed in the middle in the length direction of the two break lines. Consists of a lateral weakening line or separation that crosses two break lines A sealing line is provided, and the two vertical break lines are formed from the upper layer to the lower layer of a plurality of layers so as to reach the upper and lower edges of the side surface. It is characterized in that it is glued at a portion between the lines (claim 1).
このような梱包用の袋においては、前記縦向きの破断線が設けられている側面の上下の端縁近辺に沿って、縦向きの破断線とつながるように横向きの破断線が設けられているものが好ましい（請求項２）。In such a packaging bag, a horizontal break line is provided so as to be connected to the vertical break line along the vicinity of the upper and lower edges of the side surface on which the vertical break line is provided. Those are preferred (claim 2).
本発明の梱包体は、前記梱包用の袋と、その袋内に整列状態で密に詰められた複数個の被梱包物とからなり、前記袋の開口部が折り畳まれて封緘され、底面と同形の上面となっていることを特徴としている（請求項３）。このような梱包体においては、前記上面に、上面とほぼ同程度の大きさのアウターパッチが貼り付けられているものが好ましい（請求項４）。 Package of the present invention, prior to a bag for Kikori hull consists of a plurality of object to be packed, which is closely packed in an aligned state within the bag, the opening of the bag is sealed folded and, The upper surface has the same shape as the bottom surface (Claim 3 ). In such a package, it is preferable that an outer patch having a size substantially equal to that of the upper surface is attached to the upper surface (claim 4).
本発明の梱包用の袋（請求項１）は、開口部から被梱包物を袋の内面いっぱいに収容し、開口部を折り畳み、通常の手段で、たとえば梱包用のテープや糊で封緘することにより梱包体とすることができる 。そのとき、内容物はいわば袋によって緊縛された状態で一体化される。得られた梱包体は内部に被梱包物が詰まっているので、内部の重量は袋を通して下側の梱包体によって支持される。それにより、多段にしても安定して保管・運送することができる。 The packaging bag according to the present invention (Claim 1) accommodates the object to be packed through the opening over the entire inner surface of the bag, folds the opening, and seals it with normal means, for example, packing tape or glue. Can be used as a package. At that time, the contents are integrated in a state of being bound by a bag. Since the package to be obtained is packed with an object to be packed, the weight inside is supported by the lower package through the bag. Thereby, even if it is multistage, it can be stably stored and transported.
開梱する場合は、破断線が設けられている側面を上向きにし、破断線に沿って袋を開封する。それにより袋によって緊縛力されていた内容物が緩められ、破断した部分を広く開いて内容物を順に取り出すことができる。すなわち、梱包時には、袋に「たが張り力（フープストレス）」と同様の周方向の張力が加わっている。そして側面を縦方向に破断することによりその張力が解除され、内容物の緊縛がなくなる。そのため内容物を楽に取り出すことができる。 When unpacking, the side where the break line is provided is turned upward, and the bag is opened along the break line. As a result, the contents that have been tightly bound by the bag are loosened, and the contents can be taken out in order by widely opening the broken portion. That is, during packaging, a circumferential tension similar to “tension tension (hoop stress)” is applied to the bag. Then, by breaking the side surface in the vertical direction, the tension is released and the contents are not bound. Therefore, the contents can be taken out easily.
本発明の梱包用袋では、上記のように側面から内容物を取り出すようにしているので、梱包時に閉じた開口部は開ける必要がなく、しかも何度も向きを変えたりする必要がない。さらに本発明の袋では、側面から内容物を取り出すので、梱包時に上端開口部を粘着テープやアウターパッチなどでしっかりと封緘することができる。それにより梱包体の形態維持性が向上する。また、側面に沿って破断線を引き裂いていくと、上面および下面（寝かせた状態では両端面となっている）まで達する。その後、上面や下面と側面との境目に沿って破ると、比較的まっすぐに破ることができる。それにより大きい開口部が得られ、さらに容易に内容物を取り出すことができる。 In the packaging bag of the present invention, the contents are taken out from the side as described above, so that it is not necessary to open the opening closed at the time of packaging, and it is not necessary to change the direction many times. Further, in the bag of the present invention, the contents are taken out from the side surface, so that the upper end opening can be tightly sealed with an adhesive tape, an outer patch or the like during packaging. Thereby, the form maintainability of the package is improved. Moreover, when the breaking line is torn along the side surface, it reaches the upper surface and the lower surface (both end surfaces when laid down). Then, if it breaks along the boundary between the upper surface or the lower surface and the side surface, it can be broken relatively straight. In addition, a larger opening can be obtained, and the contents can be taken out more easily.
そして、前記袋が紙製で、底面および側面がそれぞれ矩形状であり、底面を下向きにした梱包状態で、高さの寸法が幅よりも大きく、前記破断線が、梱包状態における側面の内、面積が広い側面に、左右方向の中央部で縦方向に形成されているので、破断線がある側面を上向きにして積み上げて保管したり搬送すれば、安定した状態で保管・搬送をすることができる。しかも積み降ろした状態で向きを変えずに安定した状態で開封することができる。また、筒状の紙袋であるので、縦方向が紙の繊維の向きとなり、縦方向の破断線は比較的まっすぐに破ることができる利点がある。 And, the bag is made of paper, the bottom surface and the side surface are each rectangular, and in the packing state with the bottom surface facing downward, the height dimension is larger than the width, and the breaking line is within the side surface in the packing state, Since it is formed in the vertical direction at the center in the left and right direction on the side with a large area, it can be stored and transported in a stable state if it is stored and transported with the side with the breaking line facing up it can. Moreover, it can be opened in a stable state without changing the direction in the unloaded state. Moreover, since it is a cylindrical paper bag, the vertical direction is the direction of the fiber of the paper, and there is an advantage that the vertical breaking line can be broken relatively straight.
また、前記破断線がミシン目または切れ目であり、指を入れることができる幅で２本平行に形成され、かつ、その２本の破断線を横切る横向きの弱め線ないし切り離し部からなる開封部が設けられているので、開封部の近くを押して２本の破断線を押し破り、その部分から指を入れて開封部を摘んで引っ張るだけで、２本の破断線の間の部分をテープ状にまっすぐに破りとることができる。そのとき、２本の破断線の間で複数の層が糊付けされているので、各層を一緒に引き破ることができる。そのため、容易に開口部を形成することができる。 In addition, the break line is a perforation or a cut line, and is formed in parallel with two widths that allow a finger to be inserted , and an unsealed portion consisting of a lateral weak line or a cut-off portion that crosses the two break lines Since it is provided, push the vicinity of the opening part to break the two break lines, put your finger from that part, pick the opening part and pull the part between the two break lines in a tape shape Can be defeated straight. At that time, since a plurality of layers are glued between two break lines, each layer can be torn together. Therefore, the opening can be easily formed.
このような梱包用の袋が、前記縦向きの破断線が設けられている側面の上下の端縁近辺に沿って、縦向きの破断線とつながるように横向きの破断線が設けられている場合（請求項２）は、前記縦向きの破断線が設けられている側面の端縁近辺に沿って、縦向きの破断線とつながるように横向きの破断線が設けられているので、縦向きの破断線に沿って中央を開いた後、横向きの破断線に沿って容易に引き破ることができ、側面全体を広く開放することができる。それによりさらに容易に内容物を取り出すことができる。 When such a packaging bag is provided with a horizontal break line so as to be connected to the vertical break line along the vicinity of the upper and lower edges of the side surface on which the vertical break line is provided (claim 2) along the edge near the side where the vertical break lines are provided, the transverse rupture line so as to be connected with the vertically oriented breaking lines are provided, vertically oriented After opening the center along the breaking line, it can be easily torn along the lateral breaking line, and the entire side surface can be opened widely. Thereby, the contents can be taken out more easily.
本発明の梱包体（請求項３）は、多数の被梱包物を密に袋に収容することができ、多段に安全に積み重ねることができる。しかも、開封時には容易に被梱包物を取り出すことができる。このような梱包体が、前記上面に、上面とほぼ同程度の大きさのアウターパッチが貼り付けられている場合（請求項４）は、上面と側面との境界の稜線に沿って比較的まっすぐに破りやすい。 The packaging body of the present invention (Claim 3 ) can accommodate a large number of objects to be packed in a bag, and can be safely stacked in multiple stages. In addition, the packaged item can be easily taken out at the time of opening. When such a package has an outer patch of the same size as the upper surface attached to the upper surface (Claim 4), it is relatively straight along the ridgeline at the boundary between the upper surface and the side surface. Easy to break.

FIG. 1 is a perspective view showing an embodiment of a packaging bag according to the present invention, FIGS. 2 and 3 are perspective views showing a usage state of the packaging bag, and FIG. 4a shows an opening portion of the bag of FIG. FIG. 4b is a perspective view showing the opening procedure of the opening portion, FIG. 5 is a perspective view showing the unpacking procedure of the bag of FIG. 1, and FIG. 6 is outside the scope of the present invention . perspective view showing an example, FIG. 7 is a perspective view showing still another embodiment of the package of the present invention.
図１に示す梱包用の紙袋１０は、帯状のシートの両端を貼り合わせて形成した筒状体を適切な長さに切断し、一端の開口部を折り畳み、アウターパッチ１１を貼り付けて底面１２を形成したものである。開口部の形状および折り畳む手順は公知であるが、たとえば、印刷した帯状のシートを筒状に張り合わせ、さらに扁平にした筒状体（チューブ）を一袋分の長さに切断し、突片１３を設けるため、その一端に２本の縦方向の切れ目を入れ、両側に三角形状の展開部１４を形成するように押し拡げ、突片１３を互いに向き合うように折り曲げ、開口部を封緘するアウターパッチ１１を貼り付ける。なお、通常は突片１３を折り曲げる前にあらかじめインナーパッチを貼り付けてシール性および強度を向上させる。 A packaging paper bag 10 shown in FIG. 1 is formed by cutting a cylindrical body formed by bonding both ends of a belt-like sheet into an appropriate length, folding an opening at one end, and attaching an outer patch 11 to a bottom surface 12. Is formed. The shape of the opening and the folding procedure are known. For example, a printed strip-shaped sheet is laminated into a cylindrical shape, and a flattened cylindrical body (tube) is cut into a length corresponding to one bag. The outer patch is provided with two longitudinal cuts at one end thereof, expanded so as to form a triangular developed portion 14 on both sides, the protruding pieces 13 are bent so as to face each other, and the opening is sealed. 11 is pasted. In general, an inner patch is applied in advance before the projecting piece 13 is bent to improve the sealing performance and strength.
シート材料は強度が高く、張りおよび腰が強い材料で、伸びにくいもの、とくに包装用に用いられているクラフト紙が好ましい。梱包する内容物に応じて２層あるいは３層以上にする。また、本発明の範囲外であるが、上記の性質を満たせば、合成樹脂製のシートであってもよい。さらに紙と合成樹脂とを組み合わせた袋であってもよい。 The sheet material is a material having high strength, strong tension and elasticity, and is not easily stretched, particularly kraft paper used for packaging. You two or more layers or three layers according to the contents of the packaging. Moreover, although it is outside the scope of the present invention , a synthetic resin sheet may be used as long as the above properties are satisfied. Furthermore, the bag which combined paper and a synthetic resin may be sufficient.
紙袋の大きさは、被梱包物およびその数、配列、形態などに応じて定められる。たとえば、複数ロールのトイレットペーパを１パック包装した略直方体状のパック包装体を梱包する場合は、図２の梱包体１５の形態で、たとえば横幅４１０ｍｍ、奥行き３６０ｍｍ、高さ１０４０ｍｍ程度の大きさとする。 The size of the paper bag is determined according to the items to be packed and the number, arrangement, form, and the like. For example, when packing a substantially rectangular parallelepiped pack package in which one roll of toilet paper of a plurality of rolls is packed, the size of the package 15 in FIG. 2 is, for example, a width of 410 mm, a depth of 360 mm, and a height of about 1040 mm. .
さらに図１の状態の扁平な袋１０では、一方の側縁の山折り線１６の近辺に、２本のミシン目ないし切れ目線１７が山折り線１６と平行に形成されている。切れ目線１７は前述の三角形状の展開部１４およびその裏面側にも続いている。そしてその長さ方向の中間部に、図４ａに示すような、平行な切れ目線１７を連結する開封線１８が形成されている。切れ目線１７としては、たとえば切れ目部１７ａの長さが５〜２０ｍｍ程度、つながり部１７ｂの長さが１〜５ｍｍ程度で切れ目が断続的に連続するものが好ましい。切れ目線１７同士の間隔は、１０〜３０ｍｍ程度が好ましい。 Further, in the flat bag 10 in the state of FIG. 1, two perforations or cut lines 17 are formed in parallel with the mountain fold line 16 in the vicinity of the mountain fold line 16 on one side edge. The cut line 17 continues to the above-described triangular developed portion 14 and the back side thereof. An opening line 18 for connecting parallel cut lines 17 as shown in FIG. 4a is formed in the middle portion in the length direction. As the cut line 17, for example, it is preferable that the cut part 17 a has a length of about 5 to 20 mm and the connection part 17 b has a length of about 1 to 5 mm and the cut is intermittently continuous. The interval between the cut lines 17 is preferably about 10 to 30 mm.
開封線１８は平行な切れ目線１７と同様の切れ目線とすることができる。ただし、平行切れ目線１７同士の間隔が狭い場合は、単に切り離してもよい。また、この実施形態では開封線１８は湾曲している。それにより、押し込むときの指の位置を示すことができ、左右の切れ目線１７に開封線１８が小さい角度で連続するので引き裂きやすい。切れ目線１７は帯状のシートを筒状体に形成する前に切り刃ローラなどで形成することができる。筒状体にしてから形成することもできる。開封線１８は袋一枚分ごとに同期して作動するカッタなどで形成することができる。ただし他の工程で形成することもできる。 The opening line 18 can be a cut line similar to the parallel cut line 17. However, when the interval between the parallel cut lines 17 is narrow, they may be simply separated. In this embodiment, the opening line 18 is curved. Thereby, the position of the finger when pushing in can be shown, and since the opening line 18 is continuous with the left and right cut lines 17 at a small angle, it is easy to tear. The cut line 17 can be formed by a cutting blade roller or the like before forming a belt-like sheet into a cylindrical body. It can also be formed after forming a cylindrical body. The opening line 18 can be formed by a cutter or the like that operates in synchronism with each bag. However, it can also be formed by other steps.
なお、図１の場合は切れ目線１７は底部１２や上面（図２の符号２０ａ）まで形成されないように、底部１２や上面２０ａとの境界で止めている。それにより図５のように開封するときに横方向（矢印Ｋ４、Ｋ５方向）に破りやすい。切れ目線１７はたとえば帯状の紙を複数枚重ねた後、筒状に形成する前の工程で、一対の円板状の切り刃ローラなどで入れることができる。切れ目線１７を底部１２や上面２０ａに入れないようにするには、たとえばカッタを支持する軸を、袋一枚分ごとに同期を取りながら駆動し、カッタを断続的に帯状の紙に押し当てるようにする。図７の横向きの切れ目線４０についても、たとえばその直後に平板状のカッタを同期をとりながら押し当てて一斉に入れることができる。 In the case of FIG. 1, the cut line 17 is stopped at the boundary with the bottom 12 and the upper surface 20a so that the bottom 12 and the upper surface (reference numeral 20a in FIG. 2) are not formed. Thereby, it is easy to tear in the lateral direction (arrow K4, K5 direction) when opening as shown in FIG . After switching Re Looking 17 overlaid plurality of strip-like paper for example, before the step of forming into a tubular shape, can be put in such a pair of disc-shaped cutting edge roller. In order to prevent the cut line 17 from entering the bottom 12 or the upper surface 20a, for example, the shaft supporting the cutter is driven while synchronizing every bag, and the cutter is intermittently pressed against the belt-shaped paper. Like that. The horizontal cut line 40 in FIG. 7 can also be put together by pressing a flat cutter, for example, immediately after that while synchronizing.
上記のように構成される梱包用の紙袋１０は、図１の扁平な状態で重ねて保管する。この場合も組立前の段ボール箱を積み重ねて保管するよりスペースがはるかに少なくて済む。紙袋１０を使用する場合は、まず図１の一点鎖線１９を山折りして右端の開口部（図２の符号２０）を開き、底面１２を下にして立てる。それにより図２の想像線で示すように、上端に底面と同形状の開口部２０を有し、下端が四角形で、それぞれ四角形の前後の側面２１および左右の側面２２を有する角筒となる。図１の一点鎖線１９は側面２１、２２同士を区切る稜線１９ａとなる。この状態では、図１の三角形状の展開部１４も前後の側面２１の一部になる。切れ目線１７は前側の側面２１のほぼ中央部に縦方向に延びている。 The packaging paper bag 10 configured as described above is stored in the flat state of FIG. In this case as well, much less space is required than stacking and storing cardboard boxes before assembly. When the paper bag 10 is used, first, the one-dot chain line 19 in FIG. 1 is folded in a mountain to open the right end opening (reference numeral 20 in FIG. 2), and the bottom surface 12 is set downward. As a result, as shown by an imaginary line in FIG. 2, a rectangular tube having an opening 20 having the same shape as the bottom surface at the upper end and a square at the lower end and having front and rear side surfaces 21 and left and right side surfaces 22, respectively. The dashed-dotted line 19 of FIG. 1 becomes the ridgeline 19a which divides the side surfaces 21 and 22. FIG. In this state, the triangular development part 14 in FIG. 1 also becomes a part of the front and rear side surfaces 21. The cut line 17 extends in the longitudinal direction substantially at the center of the front side surface 21.
この紙袋１０を用いて梱包体とする場合は、たとえば図２に示すように、１段４個、３段の１２ロール入りのパック２３を矢印Ｐのように収納し、上端よりいくらか低い高さまで積み上げる。ついで上端の周囲を内向きに折り曲げて開口部２０を塞ぎ、上面２０ａを形成する。さらに梱包用の粘着テープ２４などでしっかりと封緘する。それにより略直方体状の梱包体１５が得られる。なお、上面とほぼ同程度の大きさのアウターパッチを貼り付けてもよい。 When this paper bag 10 is used as a package, for example, as shown in FIG. 2, four packs of three stages and packs of 12 rolls of 12 stages are stored as indicated by the arrow P, and the height is somewhat lower than the upper end. Stack up. Next, the periphery of the upper end is bent inward to close the opening 20 to form the upper surface 20a. Further, it is tightly sealed with an adhesive tape 24 for packing. Thereby, a substantially rectangular parallelepiped package 15 is obtained. In addition, you may affix the outer patch of the magnitude | size substantially the same as an upper surface.
得られた梱包体１５は、切れ目線１７が形成されている前側の側面２１が上になるように倒し、その上にさらにつぎの梱包体１５を乗せて多段状で保管・搬送する。切れ目線１７がある前側の側面２１およびその背面側の側面２１は、もっとも広い面であるので、その面を下にすると積み上げ時でも安定する。ただし通常は開梱のときの作業を効率的にするように切れ目線１７がある側面２１を上にする。積み上げる段数や横に並べる個数はフォークリフトの積載能力、パレットやトラックの荷台の大きさなどによる。 The obtained package 15 is tilted so that the front side surface 21 on which the cut line 17 is formed is on top, and the next package 15 is further placed thereon to be stored and transported in multiple stages. Since the front side surface 21 and the rear side surface 21 with the cut line 17 are the widest surfaces, if the surface is lowered, the side surface 21 is stable even when stacked. However, the side surface 21 with the cut line 17 is usually turned up so that the work at the time of unpacking is made efficient. The number of steps to be stacked and the number to be arranged horizontally depend on the load capacity of the forklift, the size of the pallet and truck bed, etc.
図３は紙袋１０を横向きにして、開口部２０からパック２３を横方向に押し込む場合を示している。特許文献２の自動梱包ラインで梱包する場合は、紙袋１０の開口部２０を横向きにするほうが被梱包物を一斉に充填しやすい。さらに開口部２０の周囲を折り曲げて、粘着テープを自動的に貼り付ける作業もし易い。なお、本発明の範囲外であるが、図３では幅が広い後ろ側の側面（図２の後ろ側）２１を下側にしているが、幅が狭い横側の側面２２を下側にすることもできる。ただし切れ目線１７が上向きになる状態で梱包体１５を載置するほうが、最終的に開梱する場合に便利である。そのため、幅が狭い側面２２を上下にする場合は、幅が狭い側面２２のうち、上側になる面に破断線を設けるのがこのましい。その場合は粘着テープ２４は図７のように短くする。 FIG. 3 shows a case in which the paper bag 10 is turned sideways and the pack 23 is pushed sideways through the opening 20. When packing with the automatic packing line of Patent Document 2, it is easier to fill the objects to be packed all at once when the opening 20 of the paper bag 10 is turned sideways. Further, it is easy to bend the periphery of the opening 20 and automatically apply the adhesive tape. Although not within the scope of the present invention, in FIG. 3, the wide rear side surface (the rear side in FIG. 2) 21 is on the lower side, but the narrow side surface 22 is on the lower side. You can also However, placing the packing body 15 with the cut line 17 facing upward is more convenient when finally unpacking. Therefore, when the side surface 22 with a narrow width is set up and down, it is preferable to provide a break line on the upper surface of the side surfaces 22 with a narrow width. In that case, the adhesive tape 24 is shortened as shown in FIG.
上記のようにして得られた梱包体１５は、前述の多段に積み上げた状態で保管・搬送され、問屋などの流通段階を経て販売店で開梱される。開梱時には切れ目線１７がある面を上に向け、図４ｂに示すように湾曲した開封線１８の近辺を指などで押し込み（矢印Ｋ１）、開封線１８を切断する。そして得られる隙間２５から指を入れ、端部２６を指で摘み出し、切れ目線１７を引き破るように矢印Ｋ２方向に引っ張る。紙袋は２層あるいは３層以上とし、２本の切れ目線１７の間の部分は各層同士を糊付けしておく。それにより図４ｂのように引き破るときに各層を一緒に引き破ることができる。このような糊付けは、帯状（シート状）の紙を複数枚重ねるときに行うことができる。 The package 15 obtained as described above is stored and transported in the above-described stacked state, and is unpacked at a store through a distribution stage such as a wholesaler. At the time of unpacking, the surface with the cut line 17 is turned upward, and the vicinity of the curved opening line 18 is pushed in with a finger or the like (arrow K1) as shown in FIG. Then, a finger is inserted through the obtained gap 25, the end portion 26 is picked up by the finger, and pulled in the direction of the arrow K2 so as to break the cut line 17. Paper bag a two-layer or three or more layers, portions between the two cut lines 17 Contact Ku by gluing the layers together. Thereby, the layers can be torn together when torn as in FIG. 4b. Such gluing can be performed when a plurality of sheets of sheet-like (sheet-like) paper are stacked.
上記のように切れ目線１７を引き破ると、図５の上側に示すように、上面に一対の切れ目線と同じ幅の細長い開口２７が得られる。ついで矢印Ｋ４、Ｋ４のように上面の片側２８を引き破り、さらに反対の部分２９も矢印Ｋ５、Ｋ５のように引き破る。そのとき左右の端面（図２では上面と下面）３０、３１は折り畳まれてアウターパッチや粘着テープで固定されているので強度が高く、上面と端面の境界の稜線に沿って比較的まっすぐに破ることができる。とくに端面（図２の上面２０ａ）と同形状のアウターパッチを貼り付けた梱包体では、稜線に沿ってまっすぐに破りやすい。 When the cut line 17 is broken as described above, an elongated opening 27 having the same width as the pair of cut lines is obtained on the upper surface as shown in the upper side of FIG. Next, one side 28 of the upper surface is torn like arrows K4 and K4, and the opposite portion 29 is also torn like arrows K5 and K5. At that time, the left and right end surfaces (upper and lower surfaces in FIG. 2) 30 and 31 are folded and fixed with an outer patch or adhesive tape, so that the strength is high, and they break relatively straight along the ridgeline at the boundary between the upper surface and the end surface. be able to. In particular, in a package in which an outer patch having the same shape as the end surface (upper surface 20a in FIG. 2) is attached, it is easy to break straight along the ridgeline.
破った上面の片側２８とその反対の部分２９を開くと、図５の下側に示すように、梱包体１５の上面とほぼ同じ広さの広い開口３２が得られる。この状態はトイレットペーパのパック２３は緊縛状態から開放されているので、容易に開口部から取り出すことができる。なお、パック２３の持ち手２３ａを開口３２の側、すなわち図３の切れ目線１７の側に配置しておくと、さらにパック２３を取り出しやすい。 When one side 28 of the broken upper surface 28 and the opposite portion 29 are opened, a wide opening 32 having the same width as the upper surface of the package 15 is obtained as shown in the lower side of FIG. In this state, since the toilet paper pack 23 is released from the tight binding state, it can be easily taken out from the opening. If the handle 23a of the pack 23 is arranged on the side of the opening 32, that is, the side of the cut line 17 in FIG.
上記のように、梱包体１５は上下反転したりせずに容易に開梱することができ、底部の内容物も容易に取り出すことができる。さらにこの実施形態では、破断線として切れ目１７を採用しているので、袋の内外の通気も比較的容易である。そのため、梱包体１５を積み上げたとき、空気に邪魔されず、下段の内容物によって上段の内容物の重量を支持することができる。 As described above, the packing body 15 can be easily opened without being turned upside down, and the contents at the bottom can be easily taken out. Furthermore, in this embodiment, since the cut line 17 is adopted as the breaking line, the ventilation inside and outside the bag is relatively easy. Therefore, when the packing body 15 is stacked, the weight of the upper content can be supported by the lower content without being disturbed by air.
前記実施の形態では、破断線として２本の平行な切れ目線を採用しているが、湿気を嫌う内容物の場合は、ミシン目のように開孔率が低い形態にすることもできる。さらに本発明の範囲外であるが、図６に示すように、紙袋１０の内面に強度が高いテープ３４などの芯材を貼り付けて破断線を構成することもできる。テープ３４は合成樹脂フィルム、とくに麻や合成繊維などの繊維で強化した合成樹脂フィルム、あるいは金属ないし強度が高い紙などで構成することができる。その場合の破断線は、紙袋１０を構成するシートにおけるテープ３４の側縁と対応する部位である。テープ３４を設ける場合は、切れ目線１７やミシン目を設ける必要はない。なお、テープ３４の中央部にあらかじめ分離した切り離し部３５を設けておくと、開封時にその部分から破ることができるので都合がよい。さらに切り離し部３５の近辺の端部３６を紙袋１０の外側に突出させておくと、その端部３６を摘んで引っ張るだけでまっすぐに引き裂くことができる。テープ３４は図１などの２本の切れ目線１７と組み合わせてもよく、その場合はテープ３４を２本の切れ目線１７の間の裏面側に配置する。 In the above embodiment adopts the two parallel score line as break line, in the case of contents that dislike moisture vapor can also be in the form opening rate is low as perforations. Furthermore, although outside the scope of the present invention, as shown in FIG. 6, a broken line can be formed by attaching a core material such as a high-strength tape 34 to the inner surface of the paper bag 10. The tape 34 can be composed of a synthetic resin film, in particular, a synthetic resin film reinforced with fibers such as hemp or synthetic fibers, or metal or high strength paper. The break line in that case is a part corresponding to the side edge of the tape 34 in the sheet constituting the paper bag 10. When the tape 34 is provided, it is not necessary to provide the cut line 17 or the perforation. It should be noted that it is convenient to provide a separation part 35 separated in advance in the center of the tape 34 because it can be broken from that part when opened. Further, if the end portion 36 in the vicinity of the separating portion 35 is projected to the outside of the paper bag 10, the end portion 36 can be easily torn simply by picking and pulling. The tape 34 may be combined with the two cut lines 17 shown in FIG. 1, and in this case, the tape 34 is disposed on the back side between the two cut lines 17.
なお、本発明の範囲外であるが、テープに代えて、糸やひもなどを採用することができる。その場合は１本の破断線となる。糸やひもも切れ目線と併用することができる。 In addition, although it is outside the scope of the present invention , a thread, a string, or the like can be employed instead of the tape. In that case, it becomes one broken line. Can be used in conjunction with thread and string cut lines .
図７に示す梱包体３７では、縦方向の切れ目線１７がある面３８の端縁３９近辺に沿って、さらに横向きの切れ目線４０が形成されている。それらの切れ目線４０は、切れ目線４０が設けられている面３８の、隣接する他の側面２２に近い端部まで延びている。それぞれの横向きの切れ目線４０は、縦方向の切れ目線１７と連続（交差を含む）しており、全体として略Ｈ字状の破断線が得られる。なお、横向きの切れ目線４０は、紙袋の底面１２側や開口部を閉じた端面３１（図２の上面２０ａ）４１側の稜線に沿って形成することもできる。底面１２側に設ける場合は、図１のアウターパッチ１１との境界部分に設けるのが好ましい。切れ目線４０に代えて前述のテープやひもなど、他の破断線を設けてもよい。前記横向きの切れ目線４０を設ける場合は、開口部を閉じる粘着テープ２４は側面に回らないように短いものを用いるのが好ましい。 In the packing body 37 shown in FIG. 7, a horizontal cut line 40 is formed along the vicinity of the edge 39 of the surface 38 where the vertical cut line 17 exists. The cut lines 40 extend to the end of the surface 38 where the cut line 40 is provided, close to the other adjacent side surface 22. Each horizontal cut line 40 is continuous (including an intersection) with the vertical cut line 17 and a substantially H-shaped break line is obtained as a whole. Note that the horizontal cut line 40 can also be formed along a ridge line on the bottom surface 12 side of the paper bag or the end surface 31 (upper surface 20a in FIG. 2) 41 side where the opening is closed. When provided on the bottom surface 12 side, it is preferably provided at a boundary portion with the outer patch 11 of FIG. Instead of the cut line 40, another breaking line such as the above-described tape or string may be provided. When the transverse cut line 40 is provided, it is preferable to use a short adhesive tape 24 for closing the opening so as not to turn to the side surface.
図７のようにＨ字状の破断線を形成する場合は、図５のように大きく開放する作業がさらに容易になる。とくに紙の繊維が縦方向に向いている場合は、横方向には真っ直ぐに破断しにくいが、上記のような横方向の切れ目線４０ないしテープを設ける場合は、容易に真っ直ぐに破断することができる。横方向の切れ目線４０は隣接する他の側面まで回り込む長さとすることもでき、また、隣接する他の側面に達しない長さとすることもできる。 In the case of forming an H-shaped break line as shown in FIG. 7, the work of largely opening as shown in FIG. 5 is further facilitated. In particular, when the paper fibers are oriented in the vertical direction, it is difficult to break straight in the horizontal direction. However, when the horizontal cut line 40 or tape as described above is provided, it can be easily broken straight. it can. The transverse cut line 40 can be of a length that wraps around to another adjacent side surface, or can be a length that does not reach the other adjacent side surface.
前記実施の形態では紙袋１０にトイレットペーパのパックを収容している。トイレットペーパの１パック包装のように耐圧性がある被梱包物はとくに適する。またトイレットペーパの１パック包装以外に、たとえば米の袋、茶、ペットフード、砂糖などを充填した小型の袋、その他、小袋に充填する内容物に耐圧性がある被梱包物など、他の物を収容することもできる。茶などの粉体や菓子など、小分け包装などは、いくつかを纏めたパックにした上で梱包するほうが好ましい。 In the above-described embodiment, a toilet paper pack is accommodated in the paper bag 10. A packing object having pressure resistance such as a one-pack package of toilet paper is particularly suitable. In addition to one-pack packaging of toilet paper, other items such as rice bags, tea, pet food, small bags filled with sugar, etc. Can also be accommodated. For small powder packaging such as tea powder and confectionery, it is preferable to pack some of them together.
