が表裏側面全周にわたり複合層の一層をなして
いるので強度が大きい。(1) The first image shows the composite bag of the present invention filled with the contents.
As shown in the figure. As shown in FIG. 1, a patch 13a made of paper material is attached to the bottom of the composite bag A of the present invention.
13b is attached, and the cloth 1 is exposed on the front and back surfaces. The composite bag of the present invention has the cloth 1 exposed on the front and back sides, giving it a sophisticated appearance, and the cloth 1
It is strong because it is made of a single composite layer that covers the entire circumference of the front and back sides.
(2) 以下その製袋順序について説明する。(2) The bag-making order will be explained below.
第２図は本考案複合袋の素材となる筒状袋Ｂを
示している。この筒状袋Ｂは第２ａ図に示すよう
に最内層に内層紙２、外層にクロス１、さらにク
ロス１の表裏両側面を両側紙層３が被覆してい
る。 FIG. 2 shows a cylindrical bag B that is the raw material for the composite bag of the present invention. As shown in FIG. 2a, this cylindrical bag B has an inner paper layer 2 as the innermost layer, a cloth 1 as the outer layer, and paper layers 3 on both sides of the cloth 1 on both sides thereof.
また、クロス１の上下両端部の第二水平折込線
９より外側の露出している部分には下地コート剤
６がコーテイングされている。下地コート剤６は
クロス表面の凹凸を消去し、かつ、底貼り部形成
の際ののり１１，１２との接着を良好ならしめる
ためのものである。 Further, exposed portions outside the second horizontal fold line 9 at both the upper and lower ends of the cloth 1 are coated with a base coat agent 6. The base coating agent 6 is used to erase irregularities on the surface of the cloth and to improve adhesion with the glues 11 and 12 when forming the bottom sticking portion.
第３図に第２図の筒状袋Ｂの開口１０ａ，１０
ｂを斜め折込線７を中心とし、斜め折込線折込部
ｘを折り込んだ時点Ｃを示している。 Figure 3 shows the openings 10a and 10 of the cylindrical bag B in Figure 2.
b indicates the point C when the diagonal folding line folding portion x is folded in with the diagonal folding line 7 as the center.
この時点でクロス１の下地コート剤６は底貼り
部において、斜め折込線折込部ｘの内外両端部に
三角状１ａにのみ露出している。そしてのり１
１，１２をクロス１に塗布された下地コート剤６

線９外側部分に塗布する。 At this point, the base coating agent 6 of the cloth 1 is exposed only in a triangular shape 1a at both the inner and outer ends of the diagonal fold line folding part x at the bottom sticking part. And glue 1
1 and 12 are applied to the cloth 1 and the base coating agent 6
Coat the outside of the second horizontal folding line 9 over the triangular portion 6a of the paper 3 and the paper 3.
第４図は第二水平折込線折込部ｙを折り込んだ
時点Ｄの状態を示している。この時点でクロス
１、下地コート剤６は、第二水平折込線折込部
ｙ，ｙを縦断してあらわれる。そして第４図の時

部表面側に下地コート剤６，６が露出したクロス
１表面にコーテイングされている。 FIG. 4 shows the state at time D when the second horizontal folding line folding portion y is folded. At this point, the cloth 1 and the base coating agent 6 appear longitudinally across the second horizontal folding line folding portions y, y. At time D in FIG. 4, the base coating agents 6, 6 are coated on the exposed surface of the cloth 1 on the surface side of the bottom sticking part of the second horizontal folding line folding parts y, y.
この時点で底貼り部は、のり１１，１２で接着
した接合面部分は（紙３／のり１１，１２／下地
コート剤６／クロス１）の層関係構成となる。 At this point, the bottom sticking part has a layer relationship structure of (paper 3/glue 11, 12/base coating agent 6/cloth 1) at the joint surface portion adhered with glue 11, 12.
もし、
クロス／のり／クロス
クロス／のり／下地コート剤／クロス
の層関係構成になると、のり付けすべき片面に接
着容易な紙材がないためクロス相互が直接接重な
り、接着が困難となる。 If the layered structure is cloth/glue/cloth cloth/glue/base coating agent/cloth, the cloths will come into direct contact with each other and will be difficult to adhere to since there is no paper material that is easy to adhere to on one side.
第５図はパツチ１３ａ，１３ｂを底貼り部に貼
着した時点Ｅを示している。この時点Ｅではクロ
ス１は底貼り部においてほとんど被覆され、第１
図のように内容物を充填すると箱形となる。 FIG. 5 shows a time point E when the patches 13a and 13b are attached to the bottom patch. At this point E, the cloth 1 is almost covered at the bottom sticking part, and the first
When filled with contents as shown in the figure, it becomes box-shaped.
パツチ１３ａ，１３ｂをのり付けするとき、ク
ロス１，１の表面は下地コート剤６がコーテイン
グされているので、普通ののりを用いても容易に
のり付けされる。 When pasting the patches 13a and 13b, since the surfaces of the cloths 1 and 1 are coated with the base coat agent 6, they can be easily pasted even if ordinary glue is used.
第６図は開封するときの状態Ｆを示している。 FIG. 6 shows state F when the package is opened.
開封するため、カツトテープ１５を引張ると、
パツチ１３ｂののり１４は第二水平折込線折込部
ｙ表面の下地コート剤６に塗布されているので、
容易に剥離し、開封が容易に行なわれる。また開
封される前にはパツチ１３ｂは、のり１４によ
り、斜め折込線折込部ｘの両側紙層３と接着され
ているので、パツチ１３ａの剥離を起すことはな
い。 When you pull the cut tape 15 to open it,
Since the glue 14 of the patch 13b is applied to the base coating agent 6 on the surface of the second horizontal folding line folding portion y,
Easy to peel and open. Moreover, since the patch 13b is adhered to the paper layers 3 on both sides of the diagonal fold line folding part x by the glue 14 before being opened, the patch 13a does not peel off.
開封するときは、
紙３／のり１４−（開封）−紙３
または、
紙３／のり１４／下地コート剤６−（開封）−
クロス１となる。 When opening, use paper 3/glue 14-(opened)-paper 3 or paper 3/glue 14/base coating agent 6-(opened)-
It becomes cross 1.
したがつて、のり１４の表面に直接手や空気に
触れることなく、のりのベタ付き手に触れること
がない。 Therefore, the surface of the glue 14 does not come into direct contact with hands or air, and sticky hands do not come into contact with the glue.
従来のクロスを用いないで紙に下地コート剤を
コーテイングした場合は、
貼合のときは、
紙／のり／下地コート剤／紙
の層関係にあり、
開封のときに、
紙／のり／（開封）−下コート剤／紙
の層関係になる。 When paper is coated with a base coat agent without using a conventional cloth, the layer relationship is paper/glue/base coat agent/paper during lamination, and when the package is opened, the paper/glue/(opening ) - Undercoating agent/paper layer relationship.
このため開封するときは紙／のりと下地コート
剤／紙とに分かれ、開封した剥離面ののり材の表
面が直接空気にさらされ、手がベタ付くことな
る。 For this reason, when the package is opened, the package is separated into paper/glue and base coating agent/paper, and the surface of the glue material on the peeled side is directly exposed to the air, making your hands sticky.
ａ クロス１を袋体を形成する主素材としている
ので袋体の強度が大きく、かつ側面、底貼り部
を除いた表裏面にクロスを露出しているので、
体裁が高級化できる。
a. Since the cloth 1 is used as the main material for forming the bag, the strength of the bag is high, and the cloth is exposed on the front and back sides excluding the side and bottom parts, so
The appearance can be made more sophisticated.
ｂ クロス１はその外周側面、および底貼り部が
紙３、パツチ１３ａ，１３ｂで覆われているの
で、〓付、物流中擦れにより痛まない。b Since the outer circumferential side surface and the bottom part of the cloth 1 are covered with the paper 3 and the patches 13a and 13b, the cloth 1 will not be damaged by rubbing during installation and distribution.
ｃ 底貼り部ののり付が両側紙層３相互の接着ま
たはパツチ１３ａ，１３ｂと下地コート剤６を
介してクロス１とのり付けされる。すなわちク
ロス１を直接のり付けする個所がないので、常
温による接着が可能である。c. The bottom sticking part is glued to the cloth 1 by adhering the paper layers 3 on both sides or by using the patches 13a, 13b and the base coating agent 6. That is, since there is no place where the cloth 1 is directly glued, it is possible to bond the cloth 1 at room temperature.
（クロス直かでは常態ではのり付けできない。）
ｄ 底貼り部において表面に露出するクロス１に
は下地コート剤６をコーテイングするため、ク
ロス１表面に多少凹凸があつても平滑になり、
パツチ１３ａ，１３ｂとの接着が容易である。(Gluing cannot be done normally if the cloth is directly glued.) d Since the cloth 1 exposed on the surface at the bottom attachment part is coated with the base coat agent 6, even if the surface of the cloth 1 is slightly uneven, it becomes smooth.
It is easy to adhere to patches 13a and 13b.
ｅ 底貼り部を開封するとき、のり１４は下地コ
ート剤６とパツチ１３ａ，１３ｂの間に挟まれ
ているため、のり付部ののり材がベタついて手
に触れることがない。e When the bottom sticking part is opened, since the glue 14 is sandwiched between the base coating agent 6 and the patches 13a and 13b, the glue material in the glued part does not get sticky and touch your hands.
ｆ 下地コート剤６がクロス面に接着する接着強
度を調整することにより、底貼り強度と剥離強
度が任意に設定できる。（この場合のり材の下
地コート剤に対する接着強度が、下地コート剤
のクロスに対する接着強度より大きければよ
い。）
ｇ のり貼り袋の両側部が、クロス１の上から帯
状に両側紙層３で覆われているので袋のコシが
あつて、ハンドリング性、開封後内容物の取り
出し時の自立性が優れている。f By adjusting the adhesive strength with which the base coat agent 6 adheres to the cloth surface, the bottom sticking strength and peeling strength can be set arbitrarily. (In this case, it is sufficient that the adhesive strength of the glue to the base coating agent is greater than the adhesive strength of the base coating agent to the cloth.) g. Both sides of the glue-applied bag are covered with paper layers 3 on both sides in a band shape from above the cloth 1. Because the bag is woven, the bag is stiff and has excellent handling and independence when taking out the contents after opening.
