Description

本発明は、鞄及び鞄製造方法に関するものである。 The present invention relates to a bag and a bag manufacturing method.

従来、物品を入れるための鞄の本体の縫い目といった接合部は下壁と側壁との間、及び、側壁同士の間といった屈曲部分において、垂直に又は水平に設けられている。 Conventionally, joints, such as seams, in the body of a bag for containing items are provided vertically or horizontally at bends, such as between the bottom wall and the side walls, and between the side walls.

特開２０００－３３３７１５号明細書Japanese Patent Application Laid-Open No. 2000-333715

しかしながら、鞄の本体に入れた物体は屈曲部分の接合部に当たりやすく、従来のように接合部が屈曲部分にあると接合部が破壊されやすいという不利益がある。更に、接合部が屈曲部分に平行であると物体による負荷が集中しやすく、物体により接合部が破壊されやすいという不利益がある。 However, there is a disadvantage that an object placed in the main body of the bag is likely to hit the joint of the bent portion, and the joint is likely to be broken if the joint is in the bent portion as in the conventional case. Furthermore, if the joint is parallel to the bent portion, there is a disadvantage that the load from the object tends to be concentrated and the joint is likely to be destroyed by the object.

本発明はかかる事情に鑑みてなされたものであり、その目的は、本体の屈曲部分に物体が当たっても接合部が外れにくい鞄を提供することにある。 SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide a bag in which even if an object hits the bent portion of the main body, the joint portion is unlikely to come off.

第１の発明の鞄は、鞄であって、鞄が、物体を入れるための本体を備え、本体が、２枚のシート状部材を接合することにより形成されており、本体が、下壁領域と前壁領域と後壁領域と左壁領域と右壁領域とを備え、前壁領域と後壁領域と左壁領域と右壁領域とが、下壁領域から上方に向かって延びており、前壁領域と後壁領域とが対向配置されており、左壁領域と右壁領域とが対向配置されており、前壁領域と右壁領域と後壁領域と左壁領域とが順に環状に並んでおり、２枚のシート状部材の接合部が、左壁領域と右壁領域と下壁領域とをそれぞれ対角線状に横断するように位置している、鞄である。 The bag of the first invention is a bag, the bag has a main body for containing an object, the main body is formed by joining two sheet-like members, and the main body is a lower wall region. and a front wall region, a rear wall region, a left wall region, and a right wall region, the front wall region, the rear wall region, the left wall region, and the right wall region extending upward from the lower wall region, The front wall region and the rear wall region are arranged to face each other, and the left wall region and the right wall region are arranged to face each other. The bags are arranged side by side, and the joints of the two sheet-like members are positioned so as to diagonally cross the left wall region, the right wall region, and the lower wall region.

この構成によれば、２枚のシート状部材の接合部が、左壁領域と右壁領域と下壁領域とをそれぞれ対角線状に横断するように位置しているので、鞄の屈曲部分に負荷がかかっても接合部が外れにくい。すなわち、例えば、前壁領域と右壁領域との間の屈曲部分、右壁領域と後壁領域との間の屈曲部分、後壁領域と左壁領域との間の屈曲部分、左壁領域と前壁領域との間の屈曲部分、下壁領域と前壁領域、又は後壁領域との間の屈曲部分に力が加わっても、接合部が屈曲部分に存在しないので接合部が外れにくい。また接合部が屈曲部分に対して傾斜しているので負荷が集中しにくく、接合部が外れにくい。 According to this configuration, since the joints of the two sheet-like members are positioned so as to cross the left wall region, the right wall region, and the lower wall region in a diagonal line, a load is applied to the bent portion of the bag. Even if it is applied, the joint will not come off easily. That is, for example, a curved portion between the front wall region and the right wall region, a curved portion between the right wall region and the rear wall region, a curved portion between the rear wall region and the left wall region, and a left wall region. Even if force is applied to the bent portion between the front wall region, the bent portion between the lower wall region and the front wall region, or the bent portion between the rear wall region, the joint does not easily come off because the bent portion does not exist. Also, since the joint is inclined with respect to the bent portion, the load is less likely to be concentrated and the joint is less likely to come off.

好適には、本体の上端において、シート状部材を外側に向けて凸になるように折り重ねて接合することにより、本体の上端の開口に角が形成されている。 Preferably, at the upper end of the main body, a corner is formed in the opening at the upper end of the main body by folding and joining the sheet-like member so as to protrude outward.

この構成によれば、本体の上端において、シート状部材を外側に向けて凸になるように折り重ねて接合することにより、本体の上端の開口に角が形成されているので、簡単な構造により開口に丈夫な角を形成することができる。 According to this configuration, the sheet-like member is folded so as to protrude outward at the upper end of the main body and joined to form a corner at the opening of the upper end of the main body. Strong corners can be formed in the opening.

好適には、右壁領域および左壁領域の各々が湾曲していることにより、右壁領域および左壁領域における各接合部の上部が前壁領域と後壁領域とのいずれか一方に向かって凸状に屈曲した曲線を描くように延びており、及び、右壁領域および左壁領域における各接合部の下部が上部とは逆方向に向かって凸状に屈曲した曲線を描くように延びている。 Preferably, each of the right wall region and the left wall region is curved so that the upper portion of each joint in the right wall region and the left wall region is directed toward either the front wall region or the rear wall region. The lower part of each joint in the right wall region and the left wall region extends to draw a convexly bent curve in the direction opposite to the upper part. there is

この構成によれば、右壁領域および左壁領域における各接合部の上部と下部とが逆方向に屈曲しているので、接合部が完全に直線である場合に比べて、前壁領域側からの力及び後壁領域側からの力を柔軟に吸収して接合部が破壊されることを防ぎやすい。 According to this configuration, the upper portion and the lower portion of each joint in the right wall region and the left wall region are bent in opposite directions. and the force from the rear wall region can be flexibly absorbed to prevent the joint from breaking.

（まとめ） (summary)

本実施形態によれば、２枚のシート状部材（第１のシート状部材１１及び第２のシート状部材１２）の接合部１０が、左壁領域１６と右壁領域１７と下壁領域１３とをそれぞれ対角線状に横断するように位置しているので、鞄１の屈曲部分に負荷がかかっても接合部１０が外れにくい。すなわち、例えば、前壁領域１４と右壁領域１７との間の屈曲部分、右壁領域１７と後壁領域１５との間の屈曲部分、後壁領域１５と左壁領域１６との間の屈曲部分、左壁領域１６と前壁領域１４との間の屈曲部分、下壁領域１３と前壁領域１４、又は後壁領域１５との間の屈曲部分に力が加わっても、接合部１０が屈曲部分に存在しないので接合部１０が外れにくい。また接合部１０が屈曲部分に対して平行ではなく対角線状に傾斜しているので屈曲部分に平行に物体を入れても屈曲部分に負荷が集中しにくく、接合部が外れにくい。 According to the present embodiment, the joint portion 10 of two sheet-like members (the first sheet-like member 11 and the second sheet-like member 12) has a left wall region 16, a right wall region 17, and a lower wall region 13. , so that the joint 10 does not easily come off even if a load is applied to the bent portion of the bag 1.例文帳に追加That is, for example, a bent portion between the front wall region 14 and the right wall region 17, a bent portion between the right wall region 17 and the rear wall region 15, and a bend between the rear wall region 15 and the left wall region 16 , the bend between the left wall region 16 and the front wall region 14, the bend between the lower wall region 13 and the front wall region 14, or the bend between the rear wall region 15, the joint 10 Since it does not exist in the bent portion, the joint portion 10 is difficult to come off. In addition, since the joint 10 is not parallel to the bent portion but inclined diagonally, even if an object is inserted parallel to the bent portion, the load is less likely to be concentrated on the bent portion and the joint is less likely to come off.

本実施形態によれば、本体２の上端において、シート状部材（第１のシート状部材１１及び第２のシート状部材１２）を外側に向けて凸になるように折り重ねて接合することにより、本体２の上端の開口に角（角１８及び角１９）が形成されているので、簡単な構造により開口に丈夫な角を形成することができる。 According to this embodiment, at the upper end of the main body 2, the sheet-like members (the first sheet-like member 11 and the second sheet-like member 12) are folded so as to protrude outward and are joined together. Since the corners (corners 18 and 19) are formed in the opening at the upper end of the main body 2, a strong corner can be formed in the opening with a simple structure.

本実施形態によれば、右壁領域１７および左壁領域１６における各接合部１０の上部と下部とが逆方向に屈曲しているので、接合部１０が完全に直線である場合に比べて、前壁領域１４側からの力及び後壁領域１５側からの力を柔軟に吸収して接合部１０が破壊されることを防ぎやすい。 According to the present embodiment, the upper and lower portions of each joint 10 in the right wall region 17 and the left wall region 16 are bent in opposite directions. The force from the front wall region 14 side and the force from the rear wall region 15 side are flexibly absorbed, and it is easy to prevent the joint portion 10 from being destroyed.

本実施形態によれば、２枚のシート状部材（第１のシート状部材１１及び第２のシート状部材１２）の接合部１０が、鞄１の２つの側壁領域（左壁領域１６及び右壁領域１７）及び下壁領域１３をそれぞれ対角線状に横断するように配置されるので、鞄１の屈曲部分に負荷がかかっても接合部１０が外れにくい。すなわち、屈曲部分となる第１の右辺２４、第１の左辺２５、第１の下辺２７、第２の右辺４４、第２の左辺４５、及び第２の下辺４７に接合部１０が存在しないので、これらの屈曲部分に力が加わっても接合部１０が外れにくい。 According to this embodiment, the joint portion 10 of the two sheet-like members (the first sheet-like member 11 and the second sheet-like member 12) is connected to the two side wall regions (the left wall region 16 and the right side wall region 16) of the bag 1. Since it is arranged so as to traverse the wall region 17) and the lower wall region 13 in a diagonal line, even if a load is applied to the bent portion of the bag 1, the joint 10 is unlikely to come off. That is, since the joint 10 does not exist on the first right side 24, the first left side 25, the first lower side 27, the second right side 44, the second left side 45, and the second lower side 47, which are bent portions, , the joint 10 is unlikely to come off even if force is applied to these bent portions.

本実施形態によれば、第１の左辺２５の上端６２及び第２の右辺４４の上端７１において、シート状部材（第１のシート状部材１１及び第２のシート状部材１２）を外側に向けて凸になるように折り重ねて接合することにより、本体２の上端の開口に角が形成されるので、簡単な構造により開口に丈夫な角を形成することができる。 According to this embodiment, the sheet-like members (the first sheet-like member 11 and the second sheet-like member 12) are directed outward at the upper end 62 of the first left side 25 and the upper end 71 of the second right side 44. Since the opening at the upper end of the main body 2 is formed with a corner by folding and joining so as to form a convex shape, a strong corner can be formed in the opening with a simple structure.
