特許文献１の開口部における空気抜き構造は、周縁部に沿って延びるシール線と、当該シール線が設けられない空気通路とを含み、空気通路から外部に空気が抜ける構造である。ところが、空気通路が１箇所しかないため、袋体を押圧した際に袋体内部の空気を更に効率的に排出することが望まれている。 The air vent structure at the opening of Patent Document 1 includes a seal wire extending along the peripheral edge portion and an air passage in which the seal wire is not provided, and is a structure in which air is released from the air passage to the outside. However, since there is only one air passage, it is desired that the air inside the bag body is discharged more efficiently when the bag body is pressed.

本発明は、上記に鑑みてなされたものであって、収容物品が外部に出にくく、かつ、袋体を押圧した際における内部からの空気の排出効率がより高い袋体を提供することを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to provide a bag body in which the contained article is difficult to go out and the efficiency of air discharge from the inside when the bag body is pressed is higher. And.

上述した課題を解決し、目的を達成するために、本発明に係る袋体は、開口部が設けられる袋体本体部と、前記開口部の一部を封止する複数の接合部と、を備え、前記複数の接合部におけるそれぞれの接合部は、前記開口部の開口方向に斜めに交差する方向に延び、かつ、前記開口方向に直交する方向に沿って並んで配置される。 In order to solve the above-mentioned problems and achieve the object, the bag body according to the present invention has a bag body main body portion provided with an opening and a plurality of joint portions for sealing a part of the opening. Each of the joints in the plurality of joints extends in a direction diagonally intersecting the opening direction of the opening, and is arranged side by side along a direction orthogonal to the opening direction.

本発明によれば、収容物品が外部に出にくく、かつ、袋体を押圧した際に内部の空気の排出効率が高い袋体が提供される。 According to the present invention, there is provided a bag body in which the contained article is difficult to go out and the internal air is discharged efficiently when the bag body is pressed.

[第１実施形態]
まず、第１実施形態に係る袋体について説明する。図１は、第１実施形態に係る袋体本体部を示す斜視図である。 [First Embodiment]
First, the bag body according to the first embodiment will be described. FIG. 1 is a perspective view showing a bag body main body portion according to the first embodiment.

袋体本体部１１は、第１シート２０と、第２シート２１と、を有する。第１シート２０及び第２シート２１は、それぞれ正面から見て矩形状の形状を有する。第１シート２０及び第２シート２１の材質は、例えば、熱可塑性樹脂である。第１シート２０及び第２シート２１における第１辺１２、第２辺１３及び第３辺１４は、第１シート２０及び第２シート２１が重なった状態において、周縁部同士が互いに接合されている。接合は、例えば、接着剤を用いた接着、又は、第１シート２０及び第２シート２１の周縁部同士を加熱することによる熱溶着などが適用可能である。第１辺１２と第２辺１３とが交差する部位は第１角部１６である。第１辺１２と第３辺１４とが交差する部位は第２角部１７である。第３辺１４と第４辺１５とが交差する部位は第３角部１８である。第４辺１５と第２辺１３とが交差する部位は第４角部１９である。袋体本体部１１には、第４辺１５に開口部３０が設けられる。図１において、開口部３０が上方（開口方向、第１方向Ｄ１）に向けて開放されている。即ち、開口方向は第１方向Ｄ１となる。なお、開口方向は、前記袋体本体部１１の内部に収容された収容物品を外部に取り出す際の取り出し方向である。 The bag body main body 11 has a first sheet 20 and a second sheet 21. The first sheet 20 and the second sheet 21 each have a rectangular shape when viewed from the front. The material of the first sheet 20 and the second sheet 21 is, for example, a thermoplastic resin. The peripheral edges of the first side 12, the second side 13, and the third side 14 of the first sheet 20 and the second sheet 21 are joined to each other in a state where the first sheet 20 and the second sheet 21 overlap each other. .. As the bonding, for example, adhesion using an adhesive, heat welding by heating the peripheral portions of the first sheet 20 and the second sheet 21 and the like can be applied. The portion where the first side 12 and the second side 13 intersect is the first corner portion 16. The portion where the first side 12 and the third side 14 intersect is the second corner portion 17. The portion where the third side 14 and the fourth side 15 intersect is the third corner portion 18. The portion where the fourth side 15 and the second side 13 intersect is the fourth corner portion 19. The bag body main body 11 is provided with an opening 30 on the fourth side 15. In FIG. 1, the opening 30 is opened upward (opening direction, first direction D1). That is, the opening direction is the first direction D1. The opening direction is the taking-out direction when taking out the stored article housed inside the bag body main body 11 to the outside.

図２は、第１実施形態に係る袋体を正面から見た模式図である。袋体１０は、袋体本体部１１と、複数の接合部４１と、を有する。袋体１０の内部には、長尺状の第１部品１００（収容物品）と、長さが第１部品１００よりも短い第２部品１０１（収容物品）と、が収納されている。第１部品１００と第２部品１０１とは、収容物品の一例である。第１部品１００の外径はｄ１であり、第２部品１０１の外径はｄ２である。また、袋体本体部１１の第４辺１５側（開口部３０側）の周縁部には、複数の接合部４１を含む並列部５０が設けられる。複数の接合部４１によって、第１シート２０と第２シート２１とが接合される。これにより、開口部３０の一部が封止される。なお、本実施形態では、第１シート２０及び第２シート２１の材質が熱可塑性樹脂であるため、接合部４１は熱溶着部である。即ち、第１シート２０と第２シート２１とを圧着した状態で加熱することにより、開口部３０の一部を熱溶着させて熱溶着部が形成される。 FIG. 2 is a schematic view of the bag body according to the first embodiment as viewed from the front. The bag body 10 has a bag body main body portion 11 and a plurality of joint portions 41. Inside the bag body 10, a long first component 100 (contained article) and a second component 101 (contained article) having a length shorter than that of the first component 100 are stored. The first part 100 and the second part 101 are examples of contained articles. The outer diameter of the first component 100 is d1, and the outer diameter of the second component 101 is d2. Further, a parallel portion 50 including a plurality of joint portions 41 is provided on the peripheral edge of the bag body main body 11 on the fourth side 15 side (opening 30 side). The first sheet 20 and the second sheet 21 are joined by the plurality of joints 41. As a result, a part of the opening 30 is sealed. In this embodiment, since the materials of the first sheet 20 and the second sheet 21 are thermoplastic resins, the joint portion 41 is a heat welded portion. That is, by heating the first sheet 20 and the second sheet 21 in a crimped state, a part of the opening 30 is heat-welded to form a heat-welded portion.

図３は、図２の接合部の一部を拡大した模式図である。まず、方向について説明する。袋体１０の開口部３０の開口方向（図２，３の上方）を第１方向Ｄ１とする。第１方向Ｄ１に直交する方向、即ち袋体１０の幅方向（図２，３の左右方向）を第２方向Ｄ２とする。第１方向Ｄ１に斜めに交差する方向を第３方向Ｄ３とする。具体的には、図２，３において、左側に行くに従って上方に向かう斜め方向を第３方向Ｄ３とする。特に第１実施形態では、第１方向Ｄ１と第３方向Ｄ３との交差角をαとし、α＜９０°である。第３方向Ｄ３に直交する方向を第４方向Ｄ４とする。 FIG. 3 is an enlarged schematic view of a part of the joint portion of FIG. First, the direction will be described. The opening direction (above in FIGS. 2 and 3) of the opening 30 of the bag body 10 is defined as the first direction D1. The direction orthogonal to the first direction D1, that is, the width direction of the bag body 10 (the left-right direction in FIGS. 2 and 3) is defined as the second direction D2. The direction that diagonally intersects the first direction D1 is defined as the third direction D3. Specifically, in FIGS. 2 and 3, the diagonal direction upward toward the left side is defined as the third direction D3. In particular, in the first embodiment, the intersection angle between the first direction D1 and the third direction D3 is α, and α <90 °. The direction orthogonal to the third direction D3 is referred to as the fourth direction D4.

図３に示すように、接合部４１の一例として、第１接合部４１０、第２接合部４２０及び第３接合部４３０を説明する。第１接合部４１０は、第３方向Ｄ３に沿って延びる。第１接合部４１０は、第３方向Ｄ３の一端部４１１と、第３方向Ｄ３の他端部４１２と、第４方向Ｄ４の一端部４１３と、第４方向Ｄ４の他端部４１４と、を有する。一端部４１１と他端部４１２とは平行に延びる。一端部４１３と他端部４１４とは平行に延びる。一端部４１３及び他端部４１４と一端部４１１とは直交して延びる。一端部４１３及び他端部４１４と他端部４１２とは直交して延びる。即ち、第１接合部４１０は、第３方向Ｄ３に直線状に延びる矩形状の形状を有する。 As shown in FIG. 3, as an example of the joint portion 41, the first joint portion 410, the second joint portion 420, and the third joint portion 430 will be described. The first joint 410 extends along the third direction D3. The first joint 410 includes one end 411 in the third direction D3, the other end 412 in the third direction D3, one end 413 in the fourth direction D4, and the other end 414 in the fourth direction D4. Have. One end 411 and the other end 412 extend in parallel. One end 413 and the other end 414 extend in parallel. One end 413 and the other end 414 and one end 411 extend orthogonally. One end 413, the other end 414, and the other end 412 extend orthogonally. That is, the first joint portion 410 has a rectangular shape extending linearly in the third direction D3.

また、同様に第２接合部４２０は、第３方向Ｄ３に直線状に延びる矩形状の形状を有する。第２接合部４２０は、第３方向Ｄ３の一端部４２１と、第３方向Ｄ３の他端部４２２と、第４方向Ｄ４の一端部４２３と、第４方向Ｄ４の他端部４２４と、を有する。更に同様に第３接合部４３０は、第３方向Ｄ３に直線状に延びる矩形状の形状を有する。第３接合部４３０は、第３方向Ｄ３の一端部４３１と、第３方向Ｄ３の他端部４３２と、第４方向Ｄ４の一端部４３３と、第４方向Ｄ４の他端部４３４と、を有する。第１接合部４１０、第２接合部４２０及び第３接合部４３０は、互いに平行に配置される。なお、図２に示す全ての接合部４１は、互いに平行に配置される。また、第２方向Ｄ２に沿って並ぶ複数の接合部４１は、並列部５０を構成する。 Similarly, the second joint portion 420 has a rectangular shape extending linearly in the third direction D3. The second joint portion 420 includes one end portion 421 of the third direction D3, the other end portion 422 of the third direction D3, one end portion 423 of the fourth direction D4, and the other end portion 424 of the fourth direction D4. Have. Further similarly, the third joint portion 430 has a rectangular shape extending linearly in the third direction D3. The third joint 430 includes one end 431 of the third direction D3, the other end 432 of the third direction D3, one end 433 of the fourth direction D4, and the other end 434 of the fourth direction D4. Have. The first joint portion 410, the second joint portion 420, and the third joint portion 430 are arranged in parallel with each other. All the joints 41 shown in FIG. 2 are arranged in parallel with each other. Further, the plurality of joint portions 41 arranged along the second direction D2 form a parallel portion 50.

図３に示すように、第１接合部４１０と第２接合部４２０との第４方向Ｄ４に沿った最短距離はＬ１である。最短距離Ｌ１は、第１部品１００の外径ｄ１よりも小さく、かつ、第２部品１０１の外径ｄ２よりも小さい。最短距離Ｌ１は、袋体１０から外部へ空気を排出可能な程度の大きさを有する。なお、第１接合部４１０と第２接合部４２０とは、第１方向Ｄ１においてオーバーラップしている。そのオーバーラップ長Ｌ２は、第１接合部４１０の角部４１５と第２接合部４２０の角部４２５との第２方向Ｄ２に沿った距離である。角部４１５は、第１接合部４１０において図３の状態で最も右側の部位であり、角部４２５は、第２接合部４２０において図３の状態で最も左側の部位である。なお、図２に示す全ての接合部４１について、第２方向Ｄ２に隣接する接合部４１同士の第４方向Ｄ４に沿った最短距離は、全てＬ１である。 As shown in FIG. 3, the shortest distance between the first joint portion 410 and the second joint portion 420 along the fourth direction D4 is L1. The shortest distance L1 is smaller than the outer diameter d1 of the first component 100 and smaller than the outer diameter d2 of the second component 101. The shortest distance L1 has a size capable of discharging air from the bag body 10 to the outside. The first joint portion 410 and the second joint portion 420 overlap in the first direction D1. The overlap length L2 is the distance between the corner portion 415 of the first joint portion 410 and the corner portion 425 of the second joint portion 420 along the second direction D2. The corner portion 415 is the rightmost portion of the first joint portion 410 in the state of FIG. 3, and the corner portion 425 is the leftmost portion of the second joint portion 420 in the state of FIG. For all the joints 41 shown in FIG. 2, the shortest distance between the joints 41 adjacent to the second direction D2 along the fourth direction D4 is L1.

ここで、第１部品１００及び第２部品１０１を内部に収容した袋体１０の作成方法および収容方法を簡単に説明する。 Here, a method of creating and a method of accommodating the bag body 10 in which the first component 100 and the second component 101 are housed will be briefly described.

まず、第１シート２０と第２シート２１との間に設けられる開口部３０（図１参照）から袋体１０の内部に、第１部品１００と第２部品１０１とを入れる。次に、第１シート２０及び第２シート２１の開口部部分同士を熱溶着する。これにより、開口部３０の一部を熱溶着させて熱溶着部としての複数の接合部４１である並列部５０を形成する。そして、袋体１０を押して、接合部４１同士の間から、袋体１０の内部の空気を外部に排出する。 First, the first component 100 and the second component 101 are inserted into the bag body 10 through the opening 30 (see FIG. 1) provided between the first sheet 20 and the second sheet 21. Next, the openings of the first sheet 20 and the second sheet 21 are heat-welded to each other. As a result, a part of the opening 30 is heat-welded to form a parallel portion 50 which is a plurality of joints 41 as the heat-welded portions. Then, the bag body 10 is pushed, and the air inside the bag body 10 is discharged to the outside from between the joint portions 41.

以上説明した袋体１０において、接合部４１は、開口部３０の開口方向に斜めに交差する方向（第３方向Ｄ３）に延びる。また、複数の接合部４１は、開口方向に直交する方向（第２方向Ｄ２）に沿って並んで配置される。従って、斜め方向に延びる接合部４１同士の間から空気が外部に効率的に排出され、空気の排出が接合部４１によって阻害されにくくすることができる。よって、袋体１０の内部に収容した第１部品１００及び第２部品１０１（収容物品）が接合部４１によって開口部３０から外部に出ることが抑制されると共に、袋体１０を押圧した際に袋体１０の内部の空気が外部に効率的に排出されるという効果を有する。 In the bag body 10 described above, the joint portion 41 extends in a direction (third direction D3) that diagonally intersects the opening direction of the opening portion 30. Further, the plurality of joint portions 41 are arranged side by side along a direction (second direction D2) orthogonal to the opening direction. Therefore, air can be efficiently discharged to the outside from between the joint portions 41 extending in the oblique direction, and the discharge of air can be less likely to be obstructed by the joint portions 41. Therefore, when the first part 100 and the second part 101 (contained article) housed inside the bag body 10 are suppressed from coming out from the opening 30 by the joint portion 41, and when the bag body 10 is pressed, It has the effect that the air inside the bag body 10 is efficiently discharged to the outside.

また、複数の接合部４１のうちの隣接する接合部同士の最短距離Ｌ１は、袋体本体部１１の内部に収容される第１部品１００及び第２部品１０１（収容物品）の外径ｄ１，ｄ２よりも小さい。ここで、第１部品１００の外径ｄ１は、第１部品１００（収容物品）の外形の大きさであり、第２部品１０１の外径ｄ２は、第２部品１０１（収容物品）の外形の大きさである。即ち、本実施形態では、収容物品としてピンやボルト等の長尺部材を例にとったが、本発明の収容物品は長尺部材に限定されない。従って、袋体１０の内部に収容した第１部品１００及び第２部品１０１（収容物品）が接合部４１によって開口部３０から外部に出ることが更に抑制される効果を有する。 Further, the shortest distance L1 between adjacent joints among the plurality of joints 41 is the outer diameter d1 of the first part 100 and the second part 101 (contained articles) housed inside the bag body portion 11. It is smaller than d2. Here, the outer diameter d1 of the first part 100 is the size of the outer diameter of the first part 100 (contained article), and the outer diameter d2 of the second part 101 is the outer diameter d2 of the second part 101 (contained article). The size. That is, in the present embodiment, a long member such as a pin or a bolt is taken as an example of the stored article, but the stored article of the present invention is not limited to the long member. Therefore, the first component 100 and the second component 101 (contained article) housed inside the bag body 10 have an effect of being further suppressed from coming out from the opening 30 by the joint portion 41.

さらに、それぞれの接合部４１は、直線状に延び、かつ、互いに平行に配置される。従って、直線以外の形状、例えば曲線状に延びる接合部よりも、容易に接合部を形成することができるため、作業効率の向上を図ることができる。 Further, the respective joints 41 extend linearly and are arranged parallel to each other. Therefore, since the joint portion can be formed more easily than the joint portion having a shape other than a straight line, for example, a joint portion extending in a curved shape, work efficiency can be improved.

そして、袋体本体部１１は、熱可塑性樹脂で形成され、接合部４１は、袋体本体部１１における開口部３０の一部を接合する熱溶着部である。従って、例えば、接着剤を用いる接着等の接合手段よりも、接合作業の速度が高くなり、大量生産に適するという効果を有する。 The bag body 11 is made of a thermoplastic resin, and the joint 41 is a heat-welded portion that joins a part of the opening 30 in the bag body 11. Therefore, for example, the speed of the joining work is higher than that of the joining means such as bonding using an adhesive, which has the effect of being suitable for mass production.

[第２実施形態]
次に、第２実施形態に係る袋体について説明する。図４は、第２実施形態に係る袋体を正面から見た模式図である。図５は、図４の接合部の一部を拡大した模式図である。なお、図４では、第１部品１００及び第２部品１０１を省略している。本実施形態では、第２方向に並ぶ接合部を有する並列部が複数列に配置される形態について説明する。 [Second Embodiment]
Next, the bag body according to the second embodiment will be described. FIG. 4 is a schematic view of the bag body according to the second embodiment as viewed from the front. FIG. 5 is an enlarged schematic view of a part of the joint portion of FIG. In FIG. 4, the first component 100 and the second component 101 are omitted. In the present embodiment, a mode in which parallel portions having joint portions arranged in the second direction are arranged in a plurality of rows will be described.

図４に示すように、袋体１０Ａは、接合部を複数含む並列部５０Ａを有する。並列部５０Ａは、図４の下段に配置された第１並列部５１と、上段に配置された第２並列部５２とを有する。なお、図５に示すように、第４方向Ｄ４は、第１方向Ｄ１に斜めに交差する方向でもある。第１方向Ｄ１と第４方向Ｄ４との交差角をβとし、β＜９０°である。また、α＋β＝９０°である。 As shown in FIG. 4, the bag body 10A has a parallel portion 50A including a plurality of joint portions. The parallel portion 50A has a first parallel portion 51 arranged in the lower part of FIG. 4 and a second parallel part 52 arranged in the upper part. As shown in FIG. 5, the fourth direction D4 is also a direction that diagonally intersects the first direction D1. The intersection angle between the first direction D1 and the fourth direction D4 is β, and β <90 °. Further, α + β = 90 °.

For all the joints 41A shown in FIG. 4, the shortest distance between the joints 41A adjacent to the second direction D2 along the third direction D3 is L11.

次に、上段の第２並列部５２について説明する。第２並列部５２は、第１実施形態で説明した並列部５０と同一であり、第２並列部５２を構成する接合部４１の形状も第１実施形態の接合部４１と同一である。なお、接合部４１Ａ，４１は、前記開口方向に対して互いに反対方向の斜めに交差する。即ち、接合部４１Ａは第４方向Ｄ４に延び、接合部４１は第３方向Ｄ３に延びる。ここで、第１接合部４１０の他端部４１２は、第２方向Ｄ２において、第１接合部４１０Ａの一端部４１１Ａと第２接合部４２０Ａの一端部４２１Ａとの間に配置される。第２接合部４２０の他端部４２２は、第２方向Ｄ２において、第２接合部４２０Ａの一端部４２１Ａと第３接合部４３０Ａの一端部４３１Ａとの間に配置される。このように、第１並列部５１の接合部４１Ａにおける第２並列部５２側の端部と、第２並列部５２の接合部４１における第１並列部５１側の端部とは、第２方向Ｄ２に沿って交互に配置される。 Next, the second parallel portion 52 in the upper stage will be described. The second parallel portion 52 is the same as the parallel portion 50 described in the first embodiment, and the shape of the joint portion 41 constituting the second parallel portion 52 is also the same as the joint portion 41 of the first embodiment. The joint portions 41A and 41 intersect diagonally in opposite directions with respect to the opening direction. That is, the joint portion 41A extends in the fourth direction D4, and the joint portion 41 extends in the third direction D3. Here, the other end 412 of the first joint 410 is arranged between one end 411A of the first joint 410A and one end 421A of the second joint 420A in the second direction D2. The other end 422 of the second joint 420 is arranged between one end 421A of the second joint 420A and one end 431A of the third joint 430A in the second direction D2. As described above, the end portion of the joint portion 41A of the first parallel portion 51 on the second parallel portion 52 side and the end portion of the joint portion 41 of the second parallel portion 52 on the first parallel portion 51 side are in the second direction. They are arranged alternately along D2.

また、最短距離Ｌ１は、第１部品１００の外径ｄ１よりも小さく、かつ、第２部品１０１の外径ｄ２よりも小さい。なお、第２接合部４２０と第３接合部４３０とは、第１方向Ｄ１においてオーバーラップしている。そのオーバーラップ長Ｌ２は、第２接合部４２０の角部４２５と第３接合部４３０の角部４３５との第２方向Ｄ２に沿った距離である。角部４２５は、第２接合部４２０において図５の状態で最も右側の部位であり、角部４３５は、第３接合部４３０において図５の状態で最も左側の部位である。なお、図５に示す全ての接合部４１について、第２方向Ｄ２に隣接する接合部４１同士の第４方向Ｄ４に沿った最短距離は、全てＬ１である。 Further, the shortest distance L1 is smaller than the outer diameter d1 of the first component 100 and smaller than the outer diameter d2 of the second component 101. The second joint portion 420 and the third joint portion 430 overlap in the first direction D1. The overlap length L2 is the distance between the corner portion 425 of the second joint portion 420 and the corner portion 435 of the third joint portion 430 along the second direction D2. The corner portion 425 is the rightmost portion of the second joint portion 420 in the state of FIG. 5, and the corner portion 435 is the leftmost portion of the third joint portion 430 in the state of FIG. For all the joints 41 shown in FIG. 5, the shortest distance between the joints 41 adjacent to the second direction D2 along the fourth direction D4 is L1.

以上説明した袋体１０Ａにおいて、それぞれの接合部４１Ａ，４１が、開口方向に直交する方向（第２方向）に配置されて第１並列部５１及び第２並列部５２を構成し、第１並列部５１及び第２並列部５２が開口方向に沿って２段（複数）配置され、かつ、前記開口方向に隣接する前記並列部同士における前記接合部４１Ａ，４１は、前記開口方向に対して互いに反対方向の斜めに交差する。 In the bag body 10A described above, the respective joint portions 41A and 41 are arranged in the direction orthogonal to the opening direction (second direction) to form the first parallel portion 51 and the second parallel portion 52, and the first parallel portion is formed.

Cross diagonally in the opposite direction.

従って、第１部品１００及び第２部品１０１（収容物品）が、第１並列部５１における接合部４１Ａ同士の間から抜け出た場合でも、第２並列部５２の接合部４１によって止められるため、第１部品１００及び第２部品１０１が外部へ抜け出ることを効果的に抑制することができる。なお、第２並列部５２を設けても、空気の排出が接合部４１によって阻害されにくくすることができる。 Therefore, even if the first component 100 and the second component 101 (contained article) come out from between the joint portions 41A in the first parallel portion 51, they are stopped by the joint portion 41 of the second parallel portion 52. It is possible to effectively prevent the 1st component 100 and the 2nd component 101 from coming out to the outside. Even if the second parallel portion 52 is provided, it is possible to prevent the discharge of air from being hindered by the joint portion 41.

また、第１並列部５１と第２並列部５２との第１方向Ｄ１に沿った距離（即ち、例えば一端部４１１Ａと他端部４１２との第１方向Ｄ１に沿った距離）は、特に限定されないが、小さい距離の方が袋体１０Ａの容量を大きくすることができるという効果を有する。 Further, the distance between the first parallel portion 51 and the second parallel portion 52 along the first direction D1 (that is, the distance between the one end portion 411A and the other end portion 412 along the first direction D1) is particularly limited. However, a smaller distance has the effect that the capacity of the bag body 10A can be increased.
