Description

本発明は、筒状または封筒状等の各種形状の袋の内面に形状保持用の補強部材を取付けてなる補強部材付き袋とその製造方法に関する。   The present invention relates to a bag with a reinforcing member formed by attaching a reinforcing member for shape retention to the inner surface of a bag having various shapes such as a cylinder or an envelope, and a method for manufacturing the same.

従来、内容物を充填した袋には、運搬や保管等によって袋形状が変形したり潰れたりして見栄えが悪くなったり内容物が偏在してしまうこと等を防ぐために袋の内面にボール紙等からなる補強部材を貼着したものがある。この種の補強部材付きの袋を製造するには、シート状の包材の内面に角筒状や円筒状等の予め筒状に形成した補強部材を貼着し、この筒状補強部材を覆うように包材を折り曲げたり湾曲させて側端部や上下端部を加熱シールして形成するようにしていた。
しかしながら、このような製造方法は補強部材と袋の成形を別工程で行うためにコスト高になる欠点があった。
Conventionally, a bag filled with contents has a cardboard or the like on the inner surface of the bag to prevent the bag shape from being deformed or crushed by transportation or storage, etc. Some of them have a reinforcing member attached thereto. In order to manufacture a bag with this type of reinforcing member, a reinforcing member formed in a cylindrical shape such as a rectangular tube shape or a cylindrical shape is attached to the inner surface of the sheet-like packaging material, and the cylindrical reinforcing member is covered. In this way, the packaging material is bent or curved so that the side ends and upper and lower ends are heat-sealed.
However, such a manufacturing method has a drawback in that the cost is high because the reinforcing member and the bag are formed in separate steps.

このような欠点を改善する技術として、例えば下記特許文献1に記載された包装袋の製造方法が提案されている。
この製袋方法によれば、連続シート状の包材の内面に補強部材として面強化シートを貼着し、その後包材を角筒型の製袋充填機に投入して角筒状に成形し、包材の両端部を合掌させて加熱シールすることで合掌シール部からなる縦シール部を形成することで筒状に成形する。そして、底部を加熱シールして形成した後に製袋チューブを通して内容物を充填し、上部を加熱シールして切断することで包装袋を製造していた。
得られた包装袋1は図13及び図14に示すように、筒状に成形した包材2の側面に合掌シール部3が設けられ、その内面には包材に沿って面強化シート4が貼着されている。図13の水平断面図に示すように、面強化シート4は包装袋1の角部と合掌シール部3を除いた各辺をなす内面にそれぞれ貼着されている。これによって包装袋1は角筒型ガゼット袋形状を維持できる。なお、図14は図13の包材2の合掌シール部3を有する側面を外側から見た図であり、面強化シート4を実線で包材を二点鎖線で示している。
特開平3−275408号公報
As a technique for improving such drawbacks, for example, a method for manufacturing a packaging bag described in Patent Document 1 has been proposed.
According to this bag making method, a surface reinforcing sheet is stuck as a reinforcing member on the inner surface of a continuous sheet-like packaging material, and then the packaging material is put into a square tube-type bag making and filling machine to be formed into a square tube shape. Then, both ends of the wrapping material are put into a palm and heated and sealed to form a vertical seal portion made up of a joint seal portion, thereby forming a cylindrical shape. And after forming the bottom part by heat-sealing, it filled the contents through the bag making tube, and heat-sealed and cut | disconnected the upper part, and the packaging bag was manufactured.
As shown in FIGS. 13 and 14, the obtained packaging bag 1 is provided with a joint seal portion 3 on the side surface of the packaging material 2 formed into a cylindrical shape, and a surface reinforcing sheet 4 is formed on the inner surface along the packaging material. It is stuck. As shown in the horizontal cross-sectional view of FIG. 13, the surface reinforcing sheet 4 is adhered to the inner surface that forms each side except for the corners of the packaging bag 1 and the joint seal portion 3. Thereby, the packaging bag 1 can maintain a rectangular tube-type gusset bag shape. 14 is a view of the side surface of the packaging material 2 of FIG. 13 having the palm seal portion 3 as viewed from the outside, and the surface reinforcing sheet 4 is indicated by a solid line and the packaging material is indicated by a two-dot chain line.
JP-A-3-275408

しかしながら、特許文献1に記載の包装袋では、シート状の包材2を筒状に形成した側面の貼り合わせ部である合掌シール部3の領域を除いて面強化シート4が包材2の内面に貼着されているため、包装袋1の筒形状を保持する力が弱く、合掌シール部3の片側を横方向に引っ張る負荷や合掌シール部3の包材の端部同士を上下方向にずらす負荷が働いた場合、その負荷は面強化シート4のない合掌シール部3でのみ支えなければならないために強度に不安があった。   However, in the packaging bag described in Patent Document 1, the surface reinforcing sheet 4 is provided on the inner surface of the packaging material 2 except for the area of the joint seal portion 3 which is a side bonded portion in which the sheet-like packaging material 2 is formed in a cylindrical shape. Since the force of holding the cylindrical shape of the packaging bag 1 is weak, the load that pulls one side of the palm seal portion 3 in the lateral direction and the end portions of the packaging material of the palm seal portion 3 are shifted vertically. When the load was applied, the load had to be supported only by the joint seal part 3 without the surface reinforcing sheet 4, so that the strength was uneasy.

本発明は、このような実情に鑑みて、袋の貼り合わせ部の保持強度を向上させるようにした補強部材付き袋及びその製造方法を提供することを目的とする。
また、本発明の他の目的は、上述の補強部材付き袋を比較的少ない工程数を以て低コストで製造できるようにした補強部材付き袋の製造方法を提供することである。
In view of such a situation, an object of the present invention is to provide a bag with a reinforcing member and a method for manufacturing the same, in which the holding strength of a bonded portion of the bag is improved.
Another object of the present invention is to provide a method for manufacturing a bag with a reinforcing member that enables the above-described bag with a reinforcing member to be manufactured at a low cost with a relatively small number of steps.

本発明による補強部材付き袋は、シート状の包材の内面に補強部材を固着し、前記包材の両端部を貼り合わせて形成してなる袋の貼り合わせ部を有する面の内面の領域に補強部材の両端部が位置してなる補強部材付き袋において、包材の貼り合わせ部を有する面の内面における貼り合わせ部を挟む両側の領域の少なくとも一方の領域に補強部材の両端部が固着されていることを特徴とする。
本発明によれば、包材の貼り合わせ部を有する面の内面における貼り合わせ部を挟む両側の領域の少なくとも一方の領域に補強部材の一端部と他端部の両方が固着されているために袋の形状を保持する力が大きくなると共に、貼り合わせ部を挟んで例えば一方側の包材が引っ張られても補強部材の一方の端部だけでなく他方の端部も固着されているため、貼り合わせ部を分離する負荷が小さく保持強度が高いために、型崩れしにくい。
なお、本発明による補強部材付き袋は、包材の貼り合わせ部を有する面の内面における一方の領域に補強部材の両端部が固着されていてもよいし、或いは包材の貼り合わせ部内面における両方の領域に補強部材の両端部がそれぞれ固着されていてもよい。
また、本発明による補強部材付き袋において、包材の貼り合わせ部を有する面の内面における補強部材の一方の端部に包材の両側の端部が固着されていてもよいし、或いは補強部材の両方の端部に包材の両側の端部がそれぞれ固着されていてもよい。
そのため、袋の貼り合わせ部を有する面の内面の領域における包材の両側の領域とは、貼り合わせ部を除いた両側の端部であってもよいし、貼り合わせ部を含む包材の両側の端部であってもよい。

FIG. 5 is a schematic perspective view showing a manufacturing process in the packaging bag manufacturing apparatus, FIG. 6 is a horizontal sectional view of the packaging bag on the bag making tube, and FIG. FIG. 8A and FIG. 8B are perspective views showing the main part of the bag making process.
4, 9, 11, and 12 are views of the packaging bag as viewed from the outside, and the reinforcing sheet 15 is indicated by a solid line and the film is indicated by a two-dot chain line.
First, the packaging bag 10 will be described with reference to FIGS. 1 to 3.
A packaging bag 10 shown in FIG. 1 is formed in a substantially rectangular parallelepiped shape, and is formed from a sheet-like film f as a packaging material by a bag-making machine described later, and has a substantially rectangular shape joined by a heat seal portion. The bottom portion 11 and the top portion 12 and a cylindrical portion 13 formed in, for example, a rectangular tube shape are roughly formed. On the surface of the cylindrical portion 13, a palm seal portion 14 in which both end portions of the film f are heat-sealed is joined by a heat seal. The top seal portion 12a of the top portion 12 is heat-sealed in a flat shape together with the palm seal portion 14 to form a flat flap shape, and then bent and fixed to the opposite surfaces of the tubular portion 13 by the heat seal. .

図2は包装袋10の展開図であり、横長の長方形状のフィルムfにおける中央部の筒状部13の領域に補強部材として横長の略長方形状の補強シート15が貼着されている。フィルムfの片側上部にはジッパ16が溶着されている。補強シート15は例えば比較的剛性の高い紙等からなり、横方向の両端部はフィルムfの両端部近傍の合掌シール部14まで延びている。補強シート15は、狭い範囲の仮付け接着部19のフィルムfに貼着された後、本付け接着部18で確実にフィルムfに貼着される。
図3及び図4は包装袋10の筒状部13の水平断面形状と補強シート15の凹凸構造を示すものであり、角筒形状に形成されたフィルムfの両端部が一の側面13aで接合されて合掌シール部14として加熱シールされ、側面13aに折り曲げられている。フィルムfの筒状部13の内面には合掌シール部14を除いて全周に亘って補強シート15が貼着されている。
FIG. 2 is a development view of the packaging bag 10, and a horizontally-long substantially rectangular reinforcing sheet 15 is stuck as a reinforcing member in the central cylindrical portion 13 of the horizontally-long rectangular film f. A zipper 16 is welded to the upper part of one side of the film f. The reinforcing sheet 15 is made of, for example, relatively rigid paper or the like, and both end portions in the lateral direction extend to the palm seal portions 14 in the vicinity of both end portions of the film f. The reinforcing sheet 15 is securely attached to the film f at the permanently attached adhesive portion 18 after being attached to the film f of the temporary attachment portion 19 in a narrow range.
3 and 4 show the horizontal cross-sectional shape of the cylindrical portion 13 of the packaging bag 10 and the uneven structure of the reinforcing sheet 15, and both end portions of the film f formed in a rectangular tube shape are joined by one side surface 13a. Then, it is heat-sealed as the palm seal portion 14 and is bent to the side surface 13a. A reinforcing sheet 15 is attached to the inner surface of the tubular portion 13 of the film f over the entire circumference except for the palm seal portion 14.

ここで、図4に示すように、補強シート15の横方向の両端部15a、15bは所定幅を有するものとする。図において、側面13aは合掌シール部14を挟んで右側の一方の領域13Cと左側の他方の領域13Dとを有しており、一方の領域13Cには補強シート15の一方の端部15aの基部が貼着され、他方の領域13Dには他方の端部15bの基部が貼着されている。
そして、補強シート15の一方の端部15aは合掌シール部14の長手方向中間部分に凹部21が形成され、凹部21の両側に突片21a、21aが形成されている。補強シート15の他方の端部15bは同じく長手方向中間部分に凸部22が形成され、凸部22の両側は凹片22a、22aとされている。一方の端部15aの凹部21と他方の端部15bの凸部22とは凹凸嵌合している。しかも一方の端部15aの突片21a、21aと他方の端部15bの凸部22はそれぞれフィルムfの合掌シール部14を越えて他方側に突出している。
そのため、フィルムfの側面13aの内面において、合掌シール部14の両側の領域13C、13Dには、補強シート15の一方の端部15a及び他方の端部15bの凸部22と、他方の端部15b及び一方の端部15aの突片21a、21aとがそれぞれ接着されている(図4参照)。
Here, as shown in FIG. 4, both end portions 15 a and 15 b in the lateral direction of the reinforcing sheet 15 have a predetermined width. In the figure, the side surface 13a has one region 13C on the right side and the other region 13D on the left side with the palm seal part 14 interposed therebetween, and the base portion of one end portion 15a of the reinforcing sheet 15 is included in the one region 13C. Is attached, and the base of the other end 15b is attached to the other region 13D.
The one end 15 a of the reinforcing sheet 15 is formed with a recess 21 in the middle portion in the longitudinal direction of the palm seal portion 14, and projecting pieces 21 a and 21 a are formed on both sides of the recess 21. Similarly, the other end portion 15b of the reinforcing sheet 15 is formed with a convex portion 22 at an intermediate portion in the longitudinal direction, and both sides of the convex portion 22 are formed as concave pieces 22a and 22a. The concave portion 21 of one end portion 15a and the convex portion 22 of the other end portion 15b are concavo-convexly fitted. In addition, the projecting pieces 21a, 21a of one end 15a and the convex portion 22 of the other end 15b protrude beyond the palm seal part 14 of the film f to the other side.
Therefore, on the inner surface of the side surface 13a of the film f, the regions 13C and 13D on both sides of the palm seal portion 14 include the convex portion 22 of the one end 15a and the other end 15b of the reinforcing sheet 15 and the other end. 15b and the projecting pieces 21a and 21a of one end 15a are bonded to each other (see FIG. 4).

本実施形態による包装袋10は上述の構成を有しており、次に包装袋10を製造するための製袋機30による包装袋10の製造方法について図5乃至図7により説明する。
図5に示す製袋機30において、ロール31に巻回された帯状のフィルムfが繰り出しローラ32、ダンサローラ33、ガイドローラ34を経由して引き出され、具体的構造を省略した上下方向搬送機構35によって上方へ搬送される。
上下方向搬送機構35によるフィルムfの上方繰り出し工程において、補強シート15を収容したマガジン36から順次補強シート15が繰り出されて仮付け接着部19によってフィルムfの搬送方向に直交する位置に仮付けされ、その後、本付け接着部18によって本付けされる。また、ジッパ16についても連続する線状の状態でジッパロール37から繰り出され、ガイドローラ等を介して所定長さに切断された後、フィルムfに加熱溶着される。これによって1つの包装袋10に相当する長さのフィルムfは図2に示す構成を呈する。
The packaging bag 10 according to the present embodiment has the above-described configuration. Next, a manufacturing method of the packaging bag 10 by the bag making machine 30 for manufacturing the packaging bag 10 will be described with reference to FIGS.
In the bag making machine 30 shown in FIG. 5, a belt-like film f wound around a roll 31 is drawn out via a feed roller 32, a dancer roller 33, and a guide roller 34, and a vertical transport mechanism 35 in which a specific structure is omitted. Is conveyed upward.
In the upward feeding process of the film f by the vertical transport mechanism 35, the reinforcing sheets 15 are sequentially fed out from the magazine 36 containing the reinforcing sheets 15 and temporarily attached to a position orthogonal to the transport direction of the film f by the temporary attachment unit 19. Thereafter, the book is attached by the book-attaching adhesive portion 18. The zipper 16 is also fed out from the zipper roll 37 in a continuous linear state, cut to a predetermined length via a guide roller and the like, and then heat-welded to the film f. Thus, the film f having a length corresponding to one packaging bag 10 has the configuration shown in FIG.

このようにして帯状のフィルムfに所定間隔で補強シート15とジッパ16が貼り付けられた状態で、上下方向搬送機構35による下方繰り出し工程に至ると、フィルムfは図示しない製袋ガイドを介して角筒状の製袋チューブ39(図6参照)の周囲に折り曲げられ、略角筒状に成形される。そして角筒状のフィルムfの両端部が内面同士を当接させられ、この両端部を縦シーラ40によって加熱シールさせることで合掌シール部14を形成する。
なお、縦シール部を合掌シール部14によって形成する場合、補強シート15の両端部15a、15bを互いに嵌合する凹凸構造にしないと、フィルムfや補強シート15のいずれかを左右対称でない長さにしなければならず、そうでないとフィルムfの繰り出しや製袋を滑らかに行えないという不具合が生じる。
そして、図示しないガイド部材によって合掌シール部14を側面13a上に折り曲げた後、図7に示すように側面13aの表面に合掌シール部14を当接させ、側面13aの内面に補強シート15の両端部15a、15bを凹部21と凸部22が嵌合した状態で当接させる。この状態で、側面13aの表裏両面を段差付きシーラ41と製袋チューブ39とで圧着する。これによって、側面13aの表面では合掌シール部14が溶着され、また側面13aの裏面では凹部21と凸部22が嵌合した状態で補強シート15の両端部15a、15bが熱溶着されて貼着させられる。
そして、次工程で図示しない横シーラによって筒状にしたフィルムfの底部11を溶着し(図8(a)参照)、上端をカッタで切断する。
When the reinforcing sheet 15 and the zipper 16 are attached to the belt-like film f at a predetermined interval in this way, when the downward feeding process is performed by the vertical transport mechanism 35, the film f passes through a bag making guide (not shown). It is bent around a square tube-shaped bag-making tube 39 (see FIG. 6) and formed into a substantially rectangular tube shape. Then, both end portions of the rectangular tube-shaped film f are brought into contact with each other, and the both end portions are heated and sealed by the vertical sealer 40 to form the palm seal portion 14.
In addition, when the vertical seal portion is formed by the joint seal portion 14, the length of the film f or the reinforcement sheet 15 is not symmetrical unless the both end portions 15a and 15b of the reinforcement sheet 15 have an uneven structure that fits each other. Otherwise, there is a problem that the film f cannot be fed out smoothly and bags cannot be made smoothly.
Then, after the palm seal portion 14 is bent on the side surface 13a by a guide member (not shown), the palm seal portion 14 is brought into contact with the surface of the side surface 13a as shown in FIG. 7, and both ends of the reinforcing sheet 15 are brought into contact with the inner surface of the side surface 13a. The portions 15a and 15b are brought into contact with the concave portion 21 and the convex portion 22 in a fitted state. In this state, the front and back surfaces of the side surface 13a are pressure-bonded with the stepped sealer 41 and the bag making tube 39. As a result, the joint seal portion 14 is welded on the surface of the side surface 13a, and the both end portions 15a and 15b of the reinforcing sheet 15 are heat-welded and stuck on the back surface of the side surface 13a with the concave portion 21 and the convex portion 22 fitted. Be made.
In the next step, the bottom 11 of the film f formed into a cylindrical shape by a horizontal sealer (not shown) is welded (see FIG. 8A), and the upper end is cut with a cutter.

このようにして上部が開口した包装袋10′が得られる。そして、包装袋10′を横送りして、図5に示すように、上部開口を広げて内容物を充填させる。次いで、包装袋10′の上部開口を筒状部13の合掌シール部14と共に横シーラによって平面状に加熱シールして、図8(b)に示すように、頂部12に扁平フラップ形状の頂部シール部12aを形成する。そして、頂部シール部12aは合掌シール部14と共に平面状に加熱シールされた後に折り曲げられて頂部12から両筒状部13にかけて加熱シールによって固着する。
このようにして図1に示す包装袋10ができあがる。
In this way, a packaging bag 10 'having an open top is obtained. Then, the packaging bag 10 'is laterally fed, and the upper opening is widened to fill the contents as shown in FIG. Next, the upper opening of the packaging bag 10 ′ is heated and sealed in a flat shape by a horizontal sealer together with the palm seal portion 14 of the tubular portion 13, and as shown in FIG. Part 12a is formed. The top seal portion 12a is heat-sealed in a planar shape together with the palm seal portion 14 and then bent and fixed from the top portion 12 to both cylindrical portions 13 by heat sealing.
In this way, the packaging bag 10 shown in FIG. 1 is completed.

上述のように本実施形態による包装袋10によれば、合掌シール部14を挟む側面13a内面の両側の領域13C,13Dに補強シート15の一方の端部15aと他方の端部15bの各一部がそれぞれ貼着されているために包装袋10の角筒形状を保持する力が大きいと共に、合掌シール部14のいずれか片側のフィルムfが引っ張られても、補強シート15による保持強度力が高く合掌シール部14を引き剥がす方向に大きな負荷はかからない。そのため、角筒形状の包装袋10の保持強度が高く包装袋10が型崩れしにくい。しかも、補強シート15の両方の端部15a、15bが凹凸に嵌め合わされた構造であるから、包装袋10の横シール時等にフィルムfが上下方向にずれないため不良品が発生しにくく、包装袋10の合掌シール部14の包材端部を上下方向にずらす力にも強い。
また、頂部シール部12aを扁平フラップ形状にすることで、頂部シール部12aを折り曲げる際に両端まで確実にシールできて合掌シール部14が歪まないので、ジッパ16の端縁を確実にシールでき、成形後の製袋袋10が綺麗で製品品質が高い。
As described above, according to the packaging bag 10 according to the present embodiment, each of the one end portion 15a and the other end portion 15b of the reinforcing sheet 15 is provided in the regions 13C and 13D on both sides of the inner surface of the side surface 13a sandwiching the joint seal portion 14. Since the portions are adhered to each other, the force for holding the rectangular tube shape of the packaging bag 10 is large, and even if the film f on one side of the palm seal portion 14 is pulled, the holding strength force by the reinforcing sheet 15 is high. A high load is not applied in the direction in which the palm seal portion 14 is peeled off. Therefore, the holding strength of the rectangular tube-shaped packaging bag 10 is high, and the packaging bag 10 is not easily deformed. In addition, since both ends 15a and 15b of the reinforcing sheet 15 are fitted in irregularities, the film f does not shift in the vertical direction when the packaging bag 10 is laterally sealed. It is also strong against the force of shifting the packaging material end of the palm seal part 14 of the bag 10 in the vertical direction.
Further, by making the top seal portion 12a a flat flap shape, when folding the top seal portion 12a, it can be surely sealed to both ends, and the palm seal portion 14 is not distorted, so that the edge of the zipper 16 can be reliably sealed, The molded bag 10 is beautiful and the product quality is high.

また、本実施形態による包装袋10の製造方法は、フィルムfによる包装袋10の製造工程で補強シート15をフィルムf内面に貼着してフィルムfと一体に折り込んで補強シート15付きの包装袋10を成形できるから、製造工程が簡単で製造コストを低減できる。しかも、補強シート15の両方の端部15a、15bが凹凸に嵌め合わされる構造であると重ね合わせを容易に行うことができるため、包装10の製袋機の構造を簡単にできる。   Moreover, the manufacturing method of the packaging bag 10 by this embodiment is the packaging bag with the reinforcement sheet 15 which sticks the reinforcement sheet 15 to the film f inner surface in the manufacturing process of the packaging bag 10 by the film f, and folds together with the film f. 10 can be formed, the manufacturing process is simple and the manufacturing cost can be reduced. And since it can superimpose easily if it is the structure by which both edge part 15a, 15b of the reinforcement sheet | seat 15 fits unevenness | corrugation, the structure of the bag making machine of the packaging 10 can be simplified.

次に本発明の変形例について図9乃至図11により説明するが、上述の実施形態と同一または同様の部材、部品には同一の符号を用いて説明を省略する。
図9は包装袋10における合掌シール部14の両側の領域13C、13Dでの補強シート15の接合構造の変形例を示すものである。図9(a)に示す第一変形例において、補強シート15の一方の端部15aは凹部21の両側に形成された突片21aの突出量が小さく、側面13aの一方の領域13Cに貼着されて合掌シール部14を越えない。そのため、図に示す包装袋10の側面13aにおいて合掌シール部14の他方の領域13Dでは補強シート15の他方の端部15bのみが固着され、合掌シール部14の一方の領域13Cでのみ補強シート15の一方の端部15aと他方の端部15bの凸部22の一部とが固着されている。
Next, a modified example of the present invention will be described with reference to FIGS. 9 to 11. However, the same or similar members and parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.
FIG. 9 shows a modified example of the joining structure of the reinforcing sheet 15 in the regions 13C and 13D on both sides of the joint seal portion 14 in the packaging bag 10. FIG. In the first modification shown in FIG. 9A, one end portion 15a of the reinforcing sheet 15 has a small protruding amount of protruding pieces 21a formed on both sides of the concave portion 21, and is adhered to one region 13C of the side surface 13a. Therefore, the joint seal part 14 is not exceeded. Therefore, in the side surface 13a of the packaging bag 10 shown in the figure, only the other end portion 15b of the reinforcing sheet 15 is fixed in the other region 13D of the palm seal portion 14, and the reinforcing sheet 15 is only in one region 13C of the palm seal portion 14. The one end portion 15a and a part of the convex portion 22 of the other end portion 15b are fixed.

この場合でも、合掌シール部14の一方側が引っ張られたときに負荷は合掌シール部14にかからず補強シート15の両端部15a、15bにかかるため、合掌シール部14を引きはがす力が小さく包装袋10の型崩れ等を生じにくい。
図9(b)に示す第二変形例では、第一変形例とは逆に補強シート15の一方側の端部15aにおける突片21a、21aは合掌シール部14を越えて合掌シール部14の他方の領域13Dで側面13aに固着されているが、補強シート15の他方側の端部15bにおける凸部22が合掌シール部14を越えておらず、合掌シール部14の一方の領域13Cでは補強シート15の一方の端部15aのみが固着されている。
Even in this case, when one side of the palm seal portion 14 is pulled, the load is not applied to the palm seal portion 14 but is applied to both end portions 15a and 15b of the reinforcing sheet 15. Therefore, the force for peeling the palm seal portion 14 is small. The bag 10 is less likely to lose its shape.
In the second modified example shown in FIG. 9B, contrary to the first modified example, the projecting pieces 21 a and 21 a at the end 15 a on one side of the reinforcing sheet 15 extend beyond the joint seal part 14 and the joint seal part 14. Although fixed to the side surface 13a in the other region 13D, the convex portion 22 at the end 15b on the other side of the reinforcing sheet 15 does not exceed the palm seal portion 14, and the region 13C of the palm seal portion 14 is reinforced in one region 13C. Only one end 15a of the sheet 15 is fixed.

図9(c)に示す第三変形例では、補強シート15の一方の端部15aは凹部21と1つの突片21aからなる段差形状とされ、突片21aのみが合掌シール部14を越えて側面13aの他方の領域13Dに延びている。これに対し、補強シート15の他方側の端部15bは凸部22と1つの凹片22aとからなる段差形状とされ、凸部22のみが合掌シール部14を越えて側面13aの一方の領域13Cに延びている。しかも一方の端部15aの凹部21と他方の端部15bの凸部22、そして突片21aと凹片22aとがそれぞれ対向する凹凸嵌合状態に固着されている。本第三変形例では、第一実施形態と同様に合掌シール部14の両側の領域13C、13Dに補強シート15の一方の端部15a及び他方の端部15bの各一部が固着されていて保持強度がより高い。   In the third modification shown in FIG. 9C, one end 15a of the reinforcing sheet 15 has a stepped shape composed of a recess 21 and one protruding piece 21a, and only the protruding piece 21a extends beyond the palm seal part 14. It extends to the other region 13D of the side surface 13a. On the other hand, the end 15b on the other side of the reinforcing sheet 15 has a stepped shape composed of a convex portion 22 and one concave piece 22a, and only the convex portion 22 exceeds the joint seal portion 14 and is one region of the side surface 13a. 13C. In addition, the concave portion 21 of the one end portion 15a and the convex portion 22 of the other end portion 15b, and the projecting piece 21a and the concave piece 22a are fixed in a concavity and convexity fitting state facing each other. In the third modified example, as in the first embodiment, a part of each of the one end 15a and the other end 15b of the reinforcing sheet 15 is fixed to the regions 13C and 13D on both sides of the joint seal portion 14. The holding strength is higher.

次に図10及び図11では、本発明の第二実施形態による包装袋10のフィルムfの貼り合わせ部を示している。
図10において、フィルムfによる包装袋10の側面13aにおいて、フィルムfの両端の縦シール部(貼り合わせ部)はフィルムfの側面13aの一方の領域13Cの上に他方の領域13Dが重ねられて加熱シールされた重ね合わせ部45とされている。重ね合わせ部45はいわゆる封筒型構造であり、その内面には補強シート15の両端部15a、15bが接着部18等でそれぞれ固着されている。なお、本第二実施形態では側面13aにおいてフィルムfの両端部である一方の領域13Cと他方の領域13Dに重ね合わせ部45の部分を含むものとする。
図に示す例では、包装袋10の側面13aの内側において、他方の領域13Dの基部に固着された補強シート15の他方の端部15bが一方の領域13Cまで延びて固着されている。補強シート15の一方の端部15aは側面13aの一方の領域13Cにのみ固着されており、他方の端部15bとの間に若干の間隙が設けられている。
この実施形態によれば、側面13aにおける一方の領域13Cのフィルムfによって補強シート15の両方の端部15a、15bが固着されているために、包装袋10の保持強度が高い。しかも補強シート15の両方の端部15a、15bに凹部21や凸部22等の凹凸形状を形成する必要がなく低コストである上に成形がより容易になる。
Next, in FIG.10 and FIG.11, the bonding part of the film f of the packaging bag 10 by 2nd embodiment of this invention is shown.
In FIG. 10, in the side surface 13a of the packaging bag 10 made of the film f, the vertical seal portions (bonding portions) at both ends of the film f are overlapped with the other region 13D on the one region 13C of the side surface 13a of the film f. The overlapped portion 45 is heat-sealed. The overlapping portion 45 has a so-called envelope-type structure, and both end portions 15a and 15b of the reinforcing sheet 15 are fixed to the inner surface thereof by an adhesive portion 18 or the like. In the second embodiment, the overlapping portion 45 is included in one region 13C and the other region 13D which are both ends of the film f on the side surface 13a.
In the example shown in the drawing, the other end 15b of the reinforcing sheet 15 fixed to the base of the other region 13D extends to the one region 13C and is fixed inside the side surface 13a of the packaging bag 10. One end portion 15a of the reinforcing sheet 15 is fixed only to one region 13C of the side surface 13a, and a slight gap is provided between the other end portion 15b.
According to this embodiment, since both ends 15a and 15b of the reinforcing sheet 15 are fixed by the film f in the one region 13C on the side surface 13a, the holding strength of the packaging bag 10 is high. Moreover, it is not necessary to form concave and convex shapes such as the concave portions 21 and the convex portions 22 on both end portions 15a and 15b of the reinforcing sheet 15, so that the cost is low and molding becomes easier.

なお、第二実施形態においても、図12に示すように第一実施形態による補強シート15の端部15a、15bにおける各種の凹凸形状を採用してもよい。図では補強シート15の一方の端部15bに凸部22等が形成され、他方の端部15aに凹部21等が形成されている。この場合にも、フィルムfの端部が上下方向にずれるのを確実に防止できる。しかも、この変形例の場合では、補強部材15の各端部15a、15bにフィルムfの両側の領域13C,13Dがそれぞれ貼着されている構成になる。換言すれば、フィルムfの一方及び他方の領域13C,13Dにそれぞれ補強部材15の両側端部15a、15bが貼着されているともいえる。
また、本発明による袋は角筒状の包装袋10に限定されることなく、円筒状、封筒形状等、貼り合わせ部を有する各種形状の袋に適用できる。
Also in the second embodiment, as shown in FIG. 12, various uneven shapes at the end portions 15a and 15b of the reinforcing sheet 15 according to the first embodiment may be employed. In the figure, a convex portion 22 or the like is formed at one end portion 15b of the reinforcing sheet 15, and a concave portion 21 or the like is formed at the other end portion 15a. Also in this case, it is possible to reliably prevent the end of the film f from shifting in the vertical direction. Moreover, in the case of this modification, the regions 13C and 13D on both sides of the film f are adhered to the end portions 15a and 15b of the reinforcing member 15, respectively. In other words, it can be said that the side end portions 15a and 15b of the reinforcing member 15 are adhered to one and the other regions 13C and 13D of the film f, respectively.
Further, the bag according to the present invention is not limited to the rectangular tube-shaped packaging bag 10 and can be applied to bags of various shapes having a bonding portion such as a cylindrical shape and an envelope shape.
