The back sheet 32 may be a liquid impermeable sheet, and examples thereof include a polyethylene film and a polypropylene film. The exterior sheet 33 may be a liquid permeable sheet or a liquid impermeable sheet. However, in this embodiment, a liquid-impermeable sheet is used in order to increase hydrophobicity. The exterior sheet 33 is folded at the end in the left-right direction toward the skin side, and the back sheet 32 and the shoulder strap elastic member 34 are disposed inside the folded exterior sheet 33.

図3Aに示すように、肩紐部35は、各構成部材(31、32・・・)が重ね合わせられた肩紐構成部材30を、前身頃10及び後身頃20に固定した状態で、貫通した孔部38を形成することによって設けられている。孔部38は、前側の端部に襟部15を備えた長手方向に長い略楕円形状である。肩紐構成部材30を含め、上半身部分の水着1の製造方法は、後述する。   As shown in FIG. 3A, the shoulder strap portion 35 penetrates the shoulder strap constituent member 30 in which the constituent members (31, 32...) Are superimposed on the front body 10 and the back body 20. It is provided by forming the hole 38 formed. The hole 38 has a substantially oval shape that is long in the longitudinal direction and has a collar 15 at the front end. The manufacturing method of the swimsuit 1 of the upper body part including the shoulder strap component 30 will be described later.

前身頃10は、不織布等の柔軟な2枚のシート部材11、12を備える。図2Bに示すように、非肌側シート部材12は、肌側シート部材11より非肌側に位置している。非肌側シート部材12は下端部が上側に向かって折り返されており、折り返された非肌側シートの左右方向の端部は肌側シート部材11より肌側に位置している。本実施形態において、肌側に位置する肌側シート部材11は、液透過性シートであり、親水性のエアスルー不織布やスパンボンド不織布等を例示でき、非肌側に位置する非肌側シート部材12は、液不透過性シートであり、ポリエチレンフィルムやポリプロピレンフィルム等を例示できる。2枚のシート部材11、12は、重ね合わされて、接着剤等で固定されている。   The front body 10 includes two flexible sheet members 11 and 12 such as nonwoven fabric. As shown in FIG. 2B, the non-skin side sheet member 12 is located on the non-skin side with respect to the skin side sheet member 11. The non-skin side sheet member 12 has its lower end folded back upward, and the end of the folded non-skin side sheet in the left-right direction is located on the skin side from the skin side sheet member 11. In the present embodiment, the skin-side sheet member 11 located on the skin side is a liquid-permeable sheet, and may be exemplified by a hydrophilic air-through nonwoven fabric or a spunbond nonwoven fabric, and the non-skin-side sheet member 12 located on the non-skin side. Is a liquid-impermeable sheet, and examples thereof include a polyethylene film and a polypropylene film. The two sheet members 11 and 12 are overlapped and fixed with an adhesive or the like.

前身頃10は、短辺が上側、長辺が下側に位置する略台形形状に類似した形状であり、略台形形状から襟部15を除いた形状である。襟部15は、肩紐部35より左右方向の内側を上側に向かって切り取られ、窪ませた形状であり、左右方向の中央部が最も窪んでいる。着用状態においては、襟部15は略V字形状となる。なお、前身頃10には、弾性部材が設けられていない。   The front body 10 has a shape similar to a substantially trapezoidal shape in which the short side is located on the upper side and the long side is located on the lower side, and is a shape obtained by removing the collar portion 15 from the substantially trapezoidal shape. The collar portion 15 has a shape in which the inner side in the left-right direction is cut upward from the shoulder strap portion 35 toward the upper side, and the center portion in the left-right direction is most depressed. In the wearing state, the collar portion 15 is substantially V-shaped. The front body 10 is not provided with an elastic member.

後身頃20は、不織布等の不織布等の柔軟なシート部材21、22と、左右方向に伸縮する糸ゴム等の複数の弾性部材23を備える。本実施形態において、肌側に位置する肌側シート部材21は、肌側シート部材11と同様に液透過性シートであり、非肌側に位置する非肌側シート部材22は、非肌側シート部材12と同様に、液不透過性シートである。複数の弾性部材23は、上下方向に間隔を空けて並んで配されるとともに、左右方向に伸長した状態で2枚のシート部材(21、22)の間に固定されている。図2Bに示すように、非肌側シート部材22は、肌側シート部材21より非肌側に位置しており、非肌側シート部材22の下端部は上側に向かって折り返され、折り返された部分は、肌側シート部材21より肌側に位置している。弾性部材23は、2枚のシート部材21、22の間に挟まれた状態で、接着剤等で固定されている。したがって、後身頃20は左右方向に伸縮可能であり、着用者の背面にフィットする。   The back body 20 includes flexible sheet members 21 and 22 such as a nonwoven fabric such as a nonwoven fabric, and a plurality of elastic members 23 such as a thread rubber that expands and contracts in the left-right direction. In this embodiment, the skin side sheet member 21 located on the skin side is a liquid-permeable sheet similarly to the skin side sheet member 11, and the non-skin side sheet member 22 located on the non-skin side is a non-skin side sheet. Like the member 12, it is a liquid-impermeable sheet. The plurality of elastic members 23 are arranged side by side at intervals in the vertical direction, and are fixed between the two sheet members (21, 22) in a state of extending in the left-right direction. As shown in FIG. 2B, the non-skin side sheet member 22 is positioned on the non-skin side with respect to the skin side sheet member 21, and the lower end portion of the non-skin side sheet member 22 is folded upward and folded. The part is located on the skin side from the skin side sheet member 21. The elastic member 23 is fixed with an adhesive or the like while being sandwiched between the two sheet members 21 and 22. Therefore, the back body 20 can be expanded and contracted in the left-right direction, and fits the wearer's back.

図2A及び図4に示すように、前身頃10と後身頃20の形状は異なっている。図4は、図3Aの略平面図の構成を説明する概略図である。図4においては、図2Aの略平面図から弾性部材23等を省略して示している。前身頃10及び後身頃20は、いずれも左右対称の形状を有しているが、後身頃20は、左右方向の長さより長手方向の長さが長い長方形である。一方、前身頃10は、上側に短辺、下側に長辺を有する略台形形状である。このように、前身頃10と後身頃20の形状が異なっていることで、着用者や着用させようとする人が、上半身部分の水着1の前側と後側を認識しやすくすることができる。特に、着用対象者である乳幼児は、自我が芽生え始める過程にあり、自分で使い捨て水着を着用しようとする場合がある。そのため、異なる形状の前身頃10と後身頃20備えることで、乳幼児が上半身部分の水着1の前側と後側を見分けやすくなり、乳幼児がひとりで着用しやすくさせることができる。また、乳幼児の一般的な体型は、背中よりもお腹が膨らんでいる。そのため、前身頃10と後身頃20の形状を異なるものにすることで、乳幼児に体型に適した上半身部分の水着1にすることができる。   As shown in FIGS. 2A and 4, the shapes of the front body 10 and the back body 20 are different. FIG. 4 is a schematic diagram illustrating the configuration of the schematic plan view of FIG. 3A. In FIG. 4, the elastic member 23 and the like are omitted from the schematic plan view of FIG. 2A. The front body 10 and the back body 20 both have a symmetrical shape, but the back body 20 is a rectangle having a longer length in the longitudinal direction than a length in the left-right direction. On the other hand, the front body 10 has a substantially trapezoidal shape having a short side on the upper side and a long side on the lower side. Thus, the shape of the front body 10 and the back body 20 is different, so that the wearer or the person who is trying to wear can easily recognize the front side and the back side of the swimsuit 1 of the upper body part. In particular, an infant who is a wear target is in the process of starting to develop an ego, and may try to wear a disposable swimsuit by himself. Therefore, by providing the front body 10 and the back body 20 having different shapes, the infant can easily distinguish the front side and the rear side of the swimsuit 1 of the upper body part, and the infant can be easily worn alone. In addition, the general body type of infants has a larger stomach than the back. Therefore, by making the shapes of the front body 10 and the back body 20 different, it is possible to make the swimsuit 1 of the upper body part suitable for the baby's body shape.

さらに、前身頃10の左右方向の一方から他方までの上端10fの形状が、後身頃20の左右方向の一方から他方までの上端20fの形状と異なっていることで、前身頃10と後身頃20を認識しやすくしている。つまり、図2A及び図4に示すように、後身頃20の上端20fは、左右方向に沿った略直線であるのに対し、前身頃10の上端10fは、最も上側に位置する最上端(前身頃最上端)10tと、最上端10tから側部10eの上端まで内側に向かって湾曲した湾曲部16と、最上端10tから下側に向かって窪んだ形状の襟部15を有している。湾曲部16は、着用状態において着用者の上腕を動かしやすくさせるために、内側に向かって湾曲させた形状としている。通常、人間は腕を前に動かす動作を行うことが多いため、湾曲部16を設けることで、着用者の動きを妨げてしまう恐れを軽減することができる。襟部15は、着用状態において着用者の襟元を覆う部分である。本実施形態においては、襟部15は、複数個の湾曲した形状を備え、左右方向の中央部が最も下側に位置し、左右方向の中央部から外側に向かうにつれて上側に位置しており、着用状態において略V字形状となる。このとき、前身頃10の左右方向の中央における上端10cと、最上端10tとの上下方向の長さLcは、後身頃20の左右方向の中央における上端20cと、最上端20tとの上下方向の長さよりも長い。つまり、図4に示すように、前身頃10の左右方向の中央における上端10cは、最上端10tよりも下側に位置しているため、Lcは0より大きい。一方、後身頃20の左右方向の中央における上端20cは、最上端20tと上下方向の位置がほぼ同じであるため、上下方向の長さは0となる。   Furthermore, the shape of the upper end 10f from one side to the other in the left-right direction of the front body 10 is different from the shape of the upper end 20f from one side to the other in the left-right direction of the back body 20, so that the front body 10 and the back body 20 It is easy to recognize. That is, as shown in FIGS. 2A and 4, the upper end 20 f of the back body 20 is a substantially straight line along the left-right direction, whereas the upper end 10 f of the front body 10 is the uppermost end (the front body) The uppermost end) 10t, the curved portion 16 curved inward from the uppermost end 10t to the upper end of the side portion 10e, and the collar portion 15 having a shape recessed downward from the uppermost end 10t. The bending portion 16 has a shape curved inward so that the upper arm of the wearer can be easily moved in the wearing state. Usually, since a human often performs an operation of moving his / her arm forward, providing the bending portion 16 can reduce the possibility of hindering the wearer's movement. The collar part 15 is a part which covers a wearer's collar in a wearing condition. In the present embodiment, the collar portion 15 has a plurality of curved shapes, the center portion in the left-right direction is located on the lowermost side, and is located on the upper side from the center portion in the left-right direction toward the outside. It is substantially V-shaped when worn. At this time, the vertical length Lc between the upper end 10c and the uppermost end 10t of the front body 10 in the left-right direction is the vertical length Lc between the upper end 20c and the uppermost end 20t of the rear body 20. Longer than the length. That is, as shown in FIG. 4, the upper end 10c at the center in the left-right direction of the front body 10 is located below the uppermost end 10t, so Lc is greater than zero. On the other hand, the upper end 20c at the center in the left-right direction of the back body 20 is substantially the same as the uppermost end 20t in the vertical direction, so the vertical length is zero.

上端10fと上端20fの形状が異なることで、乳幼児等は、上半身部分の水着1の前側と後側をより認識しやすくなる。また、左右方向の中央における上端10cと最上端10tとの間に所定の上下方向の長さ(Lc)を有することで、着用状態において、襟元を解放した形状とすることができるため、デザイン性を向上させることができ、着用者を正面から見た際の美観を向上させることができる。   Different shapes of the upper end 10f and the upper end 20f make it easier for an infant or the like to recognize the front side and the rear side of the swimsuit 1 in the upper body part. In addition, since it has a predetermined vertical length (Lc) between the upper end 10c and the uppermost end 10t at the center in the left-right direction, it can be shaped so that the neck is released in the worn state. Can be improved, and the beauty when the wearer is viewed from the front can be improved.

なお、本実施形態においては、前身頃10の上端10fは、最上端10tと湾曲部16と襟部15を有し、後身頃20の上端20fを略直線としたが、これに限られない。上端10f及び上端20fはいずれも直線状であってもよいし、複数の湾曲部が連続した形状のみであってもよいし、前身頃10だけでなく、後身頃20の左右方向の中央部が下側に向かって窪んでいる形状であってもよい。上端10f及び上端20fはそれぞれ任意の形状とすることができる。   In the present embodiment, the upper end 10f of the front body 10 has the uppermost end 10t, the curved portion 16, and the collar portion 15, and the upper end 20f of the rear body 20 is substantially straight, but is not limited thereto. Both the upper end 10f and the upper end 20f may be linear, may have only a shape in which a plurality of curved portions are continuous, or the center in the left-right direction of the rear body 20 as well as the front body 10 The shape may be depressed toward the lower side. Each of the upper end 10f and the upper end 20f can have an arbitrary shape.

図2A及び図4に示すように、前身頃10は後身頃20よりも大きい。つまり、前身頃10の面積は、後身頃20の面積よりも大きい。また、上下方向において、前身頃10の最も長い部分の長さ(L10)は、後身頃20の最も長い部分の長さ(L20)よりも長い(L10>L20)。図4に示すように、本実施形態においては、前身頃10の上下方向の長さが最も長い部分は、肩紐部35と重なった部分であり、前身頃10の最も下側に位置する最下端10bから最も上側に位置する最上端(前身頃最上端)10tまでの上下方向の長さはL10である。後身頃20は、上下方向の長さがほぼ一定であるため、後身頃20の最も下側に位置する最下端20bから最も上側に位置する最上端(後身頃最上端)20tまでの上下方向の長さは、左右方向の全域に亘ってL20となる。なお、前身頃10の最下端10b及び後身頃20の最下端20bは、左右方向に沿った、略平行な直線である。   As shown in FIGS. 2A and 4, the front body 10 is larger than the back body 20. That is, the area of the front body 10 is larger than the area of the back body 20. In the vertical direction, the length (L10) of the longest part of the front body 10 is longer than the length (L20) of the longest part of the back body 20 (L10> L20). As shown in FIG. 4, in the present embodiment, the longest portion of the front body 10 in the vertical direction is the portion that overlaps the shoulder strap portion 35, and is the lowest portion located on the lowermost side of the front body 10. The length in the vertical direction from the lower end 10b to the uppermost end (front end uppermost end) 10t located on the uppermost side is L10. Since the rear body 20 has a substantially constant vertical length, the rear body 20 extends in the vertical direction from the lowermost end 20b positioned on the lowermost side to the uppermost end (uppermost end of the rear body) 20t positioned on the uppermost side. The length is L20 over the entire region in the left-right direction. The lowermost end 10b of the front body 10 and the lowermost end 20b of the rear body 20 are substantially parallel straight lines along the left-right direction.

本実施形態において、側部10eと側部20eの上下方向の長さは略同一である。そのため、上述のように、前身頃10の側部10eと後身頃20の側部20eを接合してキャミソール型の上半身部分の水着1を形成すると、着用時に襟元を覆う部分となる長さLMの領域が前身頃10の側部10eの上端より上側に位置することになる。つまり、前身頃10の最下端10bと後身頃20の最下端20bの上下方向の位置を同じにすると、前身頃10の上端10tは、後身頃20の最上端20tよりも上側に位置することになる。本実施形態においては、上下方向において、前身頃10の長さが最も長い部分(L10)と後身頃20の長さが最も長い部分(L20)の差は、長さLMとなる(L10−L20=LM)。   In the present embodiment, the vertical lengths of the side portion 10e and the side portion 20e are substantially the same. Therefore, as described above, when the side part 10e of the front body 10 and the side part 20e of the back body 20 are joined to form the camisole-type upper body swimsuit 1, the length LM that becomes the part that covers the collar when worn An area | region will be located above the upper end of the side part 10e of the front body 10. FIG. That is, if the vertical position of the lowermost end 10b of the front body 10 and the lowermost end 20b of the rear body 20 are the same, the upper end 10t of the front body 10 is positioned above the uppermost end 20t of the rear body 20. Become. In the present embodiment, in the vertical direction, the difference between the longest part (L10) of the front body 10 and the longest part (L20) of the back body 20 is the length LM (L10-L20). = LM).

このような前身頃10及び後身頃20を有することで、乳幼児は前身頃10と後身頃20をより認識しやすくなる。さらに、上半身部分の水着1を着用する目的の一つである、着用者の胸部を覆うという観点においても、後身頃20よりも前身頃10をより大きくすることで、乳幼児の体型に対応して適切に着用者の胸部を覆うことができる。   By having the front body 10 and the back body 20 like this, the infant can more easily recognize the front body 10 and the back body 20. Furthermore, in view of covering the wearer's chest, which is one of the purposes of wearing the swimsuit 1 of the upper body part, the front body 10 is made larger than the back body 20 to correspond to the body shape of the infant. Can properly cover the wearer's chest.

さらに、図2Aに示すように、後身頃20には複数の弾性部材23を設けているが、前身頃10には弾性部材を設けていない。つまり、後身頃20は左右方向に伸縮するが、前身頃10は、左右方向への伸縮がほとんどない。そのため、着用状態においては、着用者を正面から見ると、図1Aのように、上半身部分の水着1には弾性部材による皺をほとんど視認することができないが、着用者を背面から見ると、図1Bのように、上半身部分の水着1に複数の皺を視認することができる。   Further, as shown in FIG. 2A, the back body 20 is provided with a plurality of elastic members 23, but the front body 10 is not provided with elastic members. That is, the back body 20 expands and contracts in the left-right direction, but the front body 10 hardly stretches in the left-right direction. Therefore, in the wearing state, when the wearer is viewed from the front, as shown in FIG. 1A, almost no wrinkles due to the elastic member can be seen in the swimsuit 1 of the upper body part, but when the wearer is viewed from the back, Like 1B, a plurality of wrinkles can be visually recognized in the swimsuit 1 of the upper body part.

図5は、着用状態の使い捨て水着100を側面から見た図である。図5においては、着用状態の乳幼児を右側から見た様子を表しており、乳幼児は両手を上に上げている。図5に示すように、乳幼児の背面は弾性部材によって適度にフィットした状態となっている一方、乳幼児の前面は、弾性部材による締め付けがないため、前身頃10は乳幼児の身体に単に被さっているような状態となり、乳幼児の前面に沿った形状となる。   FIG. 5 is a side view of the disposable swimsuit 100 in a worn state. FIG. 5 shows a state where the worn infant is viewed from the right side, and the infant raises both hands up. As shown in FIG. 5, the back surface of the infant is in a state of being appropriately fitted by the elastic member, while the front surface of the infant is not tightened by the elastic member, so the front body 10 simply covers the infant's body. It becomes such a state and becomes a shape along the front of the infant.

乳幼児は、一般的に腹部が前にせり出した体型をしているため、前面が背面よりも丸みを帯び、前面についても胸囲よりも腹囲の方が大きく、胸元から腹部にかけて膨らんだ体型となっている。例えば、前身頃10に後身頃20と同様に弾性部材を配置すると、弾性部材はより収縮しやすい部分に移動してしまう傾向があるため、身体の前面のうち膨らみの小さい胸元まで弾性部材が移動して収縮してしまうため、前身頃10が上方向に引っ張られて胸元まで上がってしまい、狭い領域に複数の弾性部材が集まってしまって胸元を過度に締め付けてしまう恐れがある。また、前身頃10に弾性部材を備えていると、乳幼児の動きに応じて前身頃10の下部が上方向に引き上げられやすくなり、上半身部分の水着1を着用しているにも関わらず、乳幼児の上半身を適切に覆うこともできなくなってしまう恐れや、引き上げられた前身頃10が乳幼児の動きを阻害してしまう恐れがある。   Infants generally have a body shape with the abdomen protruding forward, so the front is rounder than the back, and the front is larger than the chest, and the body swells from the chest to the abdomen. Yes. For example, if an elastic member is disposed on the front body 10 in the same manner as the back body 20, the elastic member tends to move to a portion that is more easily contracted. Therefore, the elastic member moves to the chest with a small bulge in the front of the body. As a result, the front body 10 is pulled upward and rises to the chest, and a plurality of elastic members gather in a narrow region, and the chest may be tightened excessively. Further, when the front body 10 is provided with an elastic member, the lower part of the front body 10 is easily lifted upward according to the movement of the infant, and the infant is wearing the swimsuit 1 of the upper body part. There is a fear that the upper body of the child cannot be properly covered, and there is a risk that the raised front body 10 may hinder the movement of the infant.

これに対し、本実施形態の上半身部分の水着1は、後身頃20に弾性部材23を備え、前身頃10に弾性部材を備えないことで、前身頃10が弾性部材によって上方向に引っ張られて弾性部材が胸元に集められて過度に収縮しないようにすることができる。また、着用状態において、弾性部材を備えていない前身頃10は、乳幼児の身体と密着しない部分を有することができるため、乳幼児の動きによって前身頃10が引き上げられてしまう恐れを軽減し、引き上げられた前身頃10によって乳幼児の動きが制限される恐れを軽減することができる。これによって、乳幼児の上半身部分を適切に覆いつつ、乳幼児の体型に応じた形状の上半身部分の水着1にすることができる。   On the other hand, the swimsuit 1 of the upper body part of this embodiment includes the elastic member 23 in the back body 20 and does not include the elastic member in the front body 10, so that the front body 10 is pulled upward by the elastic member. It is possible to prevent the elastic member from being collected at the chest and being excessively contracted. Moreover, since the front body 10 which does not have an elastic member in a wearing state can have a part which does not contact | adhere with the infant's body, the possibility that the front body 10 will be pulled up by the movement of the infant is reduced and lifted. The risk of the infant's movement being restricted by the front body 10 can be reduced. Thereby, it is possible to make the swimsuit 1 of the upper body portion of the shape corresponding to the body shape of the infant while appropriately covering the upper body portion of the infant.

さらに、上半身部分の水着1は自然状態において、前身頃10の側部10eと後身頃20の側部20eがそれぞれ接合された一対の接合部1Bが、上半身部分の水着1の後側に設けられている。上半身部分の水着1の「自然状態」とは、以下のように定義される。まず、製品として梱包されている上半身部分の水着1をパッケージから取り出した後、前身頃10及び後身頃20を左右方向の両外側に引っ張り前身頃10及び後身頃20がそれぞれ各部材単体の寸法と一致又はそれに近い長さになるまで伸長させる。この伸長させた状態を15秒間継続させた後、上半身部分の水着1の伸長させた状態を解除して机等の平面に置く。そして、この平面に置いた状態で5分間経過させた状態が上半身部分の水着1の自然状態である。   Further, in the natural state of the swimsuit 1 of the upper body part, a pair of joint parts 1B in which the side part 10e of the front body part 10 and the side part 20e of the rear body part 20 are joined are provided on the rear side of the swimsuit 1 of the upper body part. ing. The “natural state” of the swimsuit 1 of the upper body part is defined as follows. First, after taking out the swimsuit 1 of the upper body part packed as a product from the package, the front body 10 and the back body 20 are pulled to both outer sides in the left-right direction, and the front body 10 and the back body 20 are respectively the dimensions of each member. Extend until matched or close. After this stretched state is continued for 15 seconds, the stretched state of the swimsuit 1 in the upper body is released and placed on a flat surface such as a desk. And the state which passed for 5 minutes in the state put on this plane is the natural state of the swimsuit 1 of an upper body part.

上半身部分の水着1は、前身頃10に弾性部材を備えておらず、後身頃20に複数の弾性部材23を備えているため、自然状態では、弾性部材23が収縮すると、後身頃20が左右方向に縮められる。その結果、自然状態として、前身頃10を下側、後身頃20を上側として平面に置いて5分間経過させた状態では、一対の係止部1Bが上側に位置しており、前身頃10の一部(左右方向の端部の少なくとも一部)も上側に位置している。   Since the swimsuit 1 of the upper body part does not include the elastic member in the front body 10 and includes the plurality of elastic members 23 in the back body 20, in the natural state, when the elastic member 23 contracts, the back body 20 Shrink in the direction. As a result, as a natural state, in a state where the front body 10 is placed on the lower surface and the rear body 20 is placed on the flat surface for 5 minutes, the pair of locking portions 1B are located on the upper side. A part (at least a part of the end in the left-right direction) is also located on the upper side.

この上半身部分の水着1を着用すると、図5に示すように、接合部1Bは着用者のより背面側に位置している。この接合部1Bの位置は、下半身部分の水着2と比較すると明らかである。下半身部分の水着2は、前胴回り部と後胴回り部の両方に左右方向に伸縮する弾性部材を備えており、胴回り部と後胴回り部とを接合した接合部2Bは、着用者の前面と背面のほぼ境界に位置している。つまり、上半身部分の水着1の接合部1Bは、下半身部分の水着2の接合部2Bより後側に位置していることがわかる。   When this upper body swimsuit 1 is worn, as shown in FIG. 5, the joint 1 </ b> B is located on the back side of the wearer. The position of the joint 1B is apparent when compared with the swimsuit 2 of the lower body part. The lower body swimsuit 2 includes elastic members that expand and contract in the left-right direction at both the front waistline portion and the rear waistline portion, and the joint portion 2B that joins the waistline portion and the rear waistline portion is the front and back surfaces of the wearer. It is located almost at the boundary. That is, it can be seen that the joint 1B of the swimsuit 1 of the upper body part is located behind the joint 2B of the swimsuit 2 of the lower body part.

接合部1Bが後側に位置することで、接合部1Bは視認が難しい位置に設けられているため、上半身部分の水着1を着用した着用者を正面から見た際に、正面からの美観を向上させることができる。また、接合部1Bは、溶着等の接合によって硬くなっているため、背面に接合部1Bを設けることで、身体の前面や脇の下のように動きの多い部分に接合部1Bを設けた際に感じる恐れのある着用者の着用している際の違和感をより軽減させることができる。   Since the joint portion 1B is located on the rear side, the joint portion 1B is provided at a position where it is difficult to visually recognize. Therefore, when the wearer wearing the swimsuit 1 of the upper body portion is viewed from the front, the beauty from the front is obtained. Can be improved. In addition, since the joint portion 1B is hardened by joining such as welding, it is felt when the joint portion 1B is provided in a portion having a lot of movement such as the front surface or the armpit of the body by providing the joint portion 1B on the back surface. It is possible to further reduce the sense of incongruity when wearing by a feared wearer.

また、図4等に示すように、左右方向の中央部に襟部15の最も窪んだ部分が設けられており、最も下側に窪んだ部分の最下端15bは、前身頃10の上端10fが最も下側に位置する部分である。最下端15bは、キャミソール型の上半身部分の水着1の接合部1Bの上端よりも上側に位置することが好ましい。つまり、前身頃10の上端10fが、接合部1Bの上端よりも下側に位置している部分を有しないことが好ましい。キャミソール型の上半身部分の水着1は、伸長状態において、襟部15の最下端15bが、弾性部材23よりも上側に位置することになる。左右方向の一方側の係止部1Bと他方側係止部1Bによって前身頃10と後身頃20は環状につながっているため、着用時や着用しようとする際に、一対の係止部1B間に引っ張り力が働く。ここで、襟部15の最下端15bが接合部1Bの上端よりも下側に位置すると、引っ張り力によって、襟部15の最下端15bが破損の起点になりやすくなってしまう。この点、接合部1Bの上端より上側に襟部15の最下端15bを設けることで、襟部15の最下端15bが破損の起点となる恐れを軽減させることができる。   Further, as shown in FIG. 4 and the like, the most recessed portion of the collar portion 15 is provided at the center in the left-right direction, and the lowermost end 15b of the lowermost recessed portion is the upper end 10f of the front body 10. This is the lowermost part. The lowermost end 15b is preferably located above the upper end of the joint 1B of the swimsuit 1 of the upper body part of the camisole type. That is, it is preferable that the upper end 10f of the front body 10 does not have a portion located below the upper end of the joint 1B. In the swimsuit 1 of the upper body portion of the camisole type, the lowermost end 15b of the collar portion 15 is positioned above the elastic member 23 in the extended state. Since the front body 10 and the back body 20 are connected in an annular shape by the one-side locking portion 1B and the other-side locking portion 1B in the left-right direction, when wearing or trying to wear, the pair of locking portions 1B The pulling force works. Here, if the lowermost end 15b of the collar portion 15 is positioned below the upper end of the joint portion 1B, the lowermost end 15b of the collar portion 15 is likely to be a starting point of breakage due to the pulling force. In this respect, by providing the lowermost end 15b of the collar portion 15 above the upper end of the joint portion 1B, the possibility that the lowermost end 15b of the collar portion 15 becomes a starting point of damage can be reduced.

さらに、図2Aに示すように、肩紐部35の肩紐弾性部材34の後身頃20側の端部は、後身頃20の弾性部材23と厚さ方向で重なっている。これによって、例えば肩紐弾性部材34が上下方向に強く引っ張られて、肩紐弾性部材34が過度に伸長しようとしても、肩紐弾性部材34と重なっている後身頃20の弾性部材23は左右方向に伸長するため、肩紐弾性部材34の過度な上下方向への伸長を軽減させることができる。そのため、肩紐部35が上下方向の伸長によって破損したり、後身頃20から離れてしまったりしてしまう恐れを軽減することができ、肩紐構成部材30と後身頃20との固定をより強固にすることができる。   Furthermore, as shown to FIG. 2A, the edge part by the side of the back body 20 of the shoulder strap elastic member 34 of the shoulder strap part 35 has overlapped with the elastic member 23 of the back body 20 in the thickness direction. Thus, for example, even if the shoulder strap elastic member 34 is pulled strongly in the vertical direction and the shoulder strap elastic member 34 tries to extend excessively, the elastic member 23 of the back body 20 that overlaps the shoulder strap elastic member 34 moves in the left-right direction. Therefore, excessive extension of the shoulder strap elastic member 34 in the vertical direction can be reduced. Therefore, it is possible to reduce the risk that the shoulder strap portion 35 is damaged due to the extension in the vertical direction or is separated from the back body 20, and the shoulder strap constituting member 30 and the back body 20 are more firmly fixed. Can be.

以上の上半身部分の水着1の基本構成に加えて、フリル等の装飾を加えてもよい。着用対象者は主に女児であることから、可愛い装飾等を加えることで着用者等の関心をより引くことができる。例えば、前身頃10及び後身頃20に複数の襞を備えたフリル(図示せず)を設けることができる。このとき、前身頃10に設けた前フリルの襞の数と後身頃20に設けた後フリル20の襞の数を異なるものにしてもよい。襞の数が異なるフリルを備えることで、乳幼児は上半身部分の水着1の前側と後側を認識しやすくなる。   In addition to the basic configuration of the swimsuit 1 of the upper body part, decoration such as frills may be added. Since the person to be worn is mainly a girl child, the interest of the wearer and the like can be further increased by adding a cute decoration or the like. For example, the front body 10 and the back body 20 can be provided with frills (not shown) having a plurality of heels. At this time, the number of heels of the front frill provided on the front body 10 and the number of heels of the back frill 20 provided on the back body 20 may be different. By providing the frills with different numbers of heels, the infant can easily recognize the front side and the rear side of the swimsuit 1 of the upper body part.

さらに、前フリルの襞の数を後フリルの襞の数より多くすることがより好ましい。前側により多くの襞を設けることで、着用者を正面から見たときの美観を向上させることができる。また、乳幼児は上半身部分の水着1の前側と後側を認識よりしやすくなる。   Furthermore, it is more preferable that the number of front ruffle wrinkles is larger than the number of rear frill wrinkles. By providing more heels on the front side, it is possible to improve the beauty when the wearer is viewed from the front. In addition, the infant can more easily recognize the front side and the rear side of the swimsuit 1 in the upper body part.

また、前フリルだけを設けて、後フリルを設けないものであってもよい。少なくとも前側にフリルを設けることで、着用者を正面から見たときの美観を向上させることができる。   Further, only the front frill may be provided and the rear frill may not be provided. By providing the frill at least on the front side, it is possible to improve the beauty when the wearer is viewed from the front.

なお、上半身部分の水着1に加える装飾は、フリルだけに限られない。図柄、スパンコール、ラインストーン等、乳幼児が喜ぶ装飾を適宜加えることができる。   In addition, the decoration added to the swimsuit 1 of an upper body part is not restricted only to a frill. Decorations that children enjoy, such as symbols, sequins, and rhinestones, can be added as appropriate.

なお、上半身部分の水着1の肩紐部35の厚さ方向に重ねられた資材の数が、前身頃10及び後身頃20の厚さ方向に重ねられた資材の数よりも多いことがより好ましい。肩紐部35は、前身頃10及び後身頃20よりも左右方向の長さが短いにも関わらず、着用時や着用中には、着用者の動き等によって、上下方向の力が多く加えられる部分であることから破損しやすくなってしまう。そのため、肩紐部35の厚さ方向に重ねられた資材の数をより多くすることで、肩紐部35が破損する恐れをより軽減させることができる。   In addition, it is more preferable that the number of materials stacked in the thickness direction of the shoulder strap portion 35 of the upper body swimsuit 1 is larger than the number of materials stacked in the thickness direction of the front body 10 and the back body 20. . Although the shoulder strap portion 35 is shorter in the left-right direction than the front body 10 and the back body 20, a large amount of force in the vertical direction is applied during wearing or during wearing due to the movement of the wearer. It is easy to break because it is a part. Therefore, by increasing the number of materials stacked in the thickness direction of the shoulder strap portion 35, the risk of the shoulder strap portion 35 being damaged can be further reduced.

また、肩紐部35が破損する恐れをより軽減すべく、1枚の外装シート33の左右方向の端部が肌側に向かって折り返されていることが好ましい。更には、外層シート33の折り返された部分にフィルムを介在させることが好ましい。前述した実施形態においては、図3Bに示すように、肌側から順に、外装シート33、バックシート32、外装シート33を重ねることで、より剛性を高めている。また、肩紐部35が、外装シート33よりも剛性の高いポリエチレンフィルムやポリプロピレンフィルム等の液不透過性のフィルムシートからなるバックシート32を備えることで、肩紐部35の破損をより軽減している。   Moreover, in order to further reduce the possibility of the shoulder strap portion 35 being damaged, it is preferable that the end portion in the left-right direction of the single exterior sheet 33 is folded toward the skin side. Furthermore, it is preferable to interpose a film in the folded portion of the outer layer sheet 33. In the embodiment described above, as shown in FIG. 3B, the rigidity is further enhanced by stacking the exterior sheet 33, the back sheet 32, and the exterior sheet 33 in order from the skin side. Further, the shoulder strap portion 35 includes a back sheet 32 made of a liquid-impermeable film sheet such as a polyethylene film or a polypropylene film having a rigidity higher than that of the exterior sheet 33, thereby further reducing damage to the shoulder strap portion 35. ing.

さらに、肩紐部35には、肩紐弾性部材34を備えて、肩紐部35の上下方向の伸縮性を付与している。肩紐弾性部材34の剛性によって上下方向の力による肩紐部35の破損を防ぐとともに、着用者の身体の大きさの違いに対応すべく伸縮による調整が可能となっている。   Furthermore, the shoulder strap portion 35 is provided with a shoulder strap elastic member 34 to give the shoulder strap portion 35 elasticity in the vertical direction. The rigidity of the shoulder strap elastic member 34 prevents damage to the shoulder strap portion 35 due to the force in the vertical direction, and adjustment by expansion and contraction is possible to cope with the difference in the size of the wearer's body.

なお、本実施形態においては、1つの肩紐構成部材30が一対の肩紐部35を備えて、一方側の肩紐部35と他方側の肩紐部35が、肩紐固定部36でつながっている構成としたが、これに限られない。一方側の肩紐部35と他方側の肩紐部35が分離していてもよい。これによって、任意の形状の肩紐部35を任意の場所に設けることができるため、上半身部分の水着1の着心地やデザイン性を向上させることができる。但し、1つの肩紐構成部材30が一対の肩紐部35を備えて、一方側の肩紐部35と他方側の肩紐部35が、肩紐固定部36でつながっている構成とすることで、肩紐固定部36をより広くすることができ、肩紐部35と前身頃10又は後身頃20との接合強度をより向上させることができる。   In the present embodiment, one shoulder strap constituting member 30 includes a pair of shoulder strap portions 35, and one shoulder strap portion 35 and the other shoulder strap portion 35 are connected by a shoulder strap fixing portion 36. However, the present invention is not limited to this. The shoulder strap portion 35 on one side and the shoulder strap portion 35 on the other side may be separated. Thereby, since the shoulder strap part 35 of arbitrary shapes can be provided in arbitrary places, the comfort and design property of the swimsuit 1 of an upper body part can be improved. However, one shoulder strap constituting member 30 includes a pair of shoulder strap portions 35, and the shoulder strap portion 35 on one side and the shoulder strap portion 35 on the other side are connected by a shoulder strap fixing portion 36. Thus, the shoulder strap fixing portion 36 can be made wider, and the bonding strength between the shoulder strap portion 35 and the front body 10 or the back body 20 can be further improved.

以下、製造装置200を参照しつつ、各工程について説明する。図7に示す製造装置200は、上記の各工程(S201〜S211)を実施することによって、上半身部分の水着1を連続的に製造する。製造装置200は、搬送機構201と、接着領域形成機構210と、弾性部材配置機構220と、重ね合せ機構230と、弾性部材切断機構240と、基材切断機構250と、肩紐構成部材接合機構260と、孔部切り抜き機構270と、折り畳み機構280と、溶着機構290と、切り離し機構300と、を備える。   Hereinafter, each process will be described with reference to the manufacturing apparatus 200. The manufacturing apparatus 200 shown in FIG. 7 manufactures the swimsuit 1 of the upper body part continuously by performing each said process (S201-S211). The manufacturing apparatus 200 includes a transport mechanism 201, an adhesion region forming mechanism 210, an elastic member arrangement mechanism 220, an overlapping mechanism 230, an elastic member cutting mechanism 240, a base material cutting mechanism 250, and a shoulder strap constituent member joining mechanism. 260, a hole cutout mechanism 270, a folding mechanism 280, a welding mechanism 290, and a separation mechanism 300.

まず、上半身部分の水着1の基材a(b)(以下、単に「基材」ともいう。)が搬送機構201によって、所定の搬送速度で搬送される。「上半身部分の水着1の基材」とは、前身頃10と後身頃20を構成する非肌側シート部材12、22(又は、肌側シート部材11、21)を上下方向に並べてつながった状態で、左右方向に連続してなる帯状の部材であり、基材aは、非肌側シート部材が連続してなる帯状のシート部材で、基材bは、肌側シート部材が連続してなる帯状のシート部材である。なお、「搬送方向」とは、図2Aにおける前身頃10、後身頃20の左右方向に沿った方向である。以下の説明では、搬送方向と交差する方向(すなわち前身頃10、後身頃20の上下方向に沿った方向)を「交差方向」ともいう。   First, the base material a (b) (hereinafter also simply referred to as “base material”) of the swimsuit 1 in the upper body part is transported by the transport mechanism 201 at a predetermined transport speed. The “base material of the swimsuit 1 of the upper body part” is a state in which the non-skin side sheet members 12 and 22 (or the skin side sheet members 11 and 21) constituting the front body 10 and the back body 20 are arranged side by side in the vertical direction. The base material a is a belt-like sheet member in which the non-skin-side sheet member is continuous, and the base material b is made of the skin-side sheet member in succession. It is a strip-shaped sheet member. The “transport direction” is a direction along the left-right direction of the front body 10 and the back body 20 in FIG. 2A. In the following description, a direction that intersects the conveyance direction (that is, a direction along the vertical direction of the front body 10 and the back body 20) is also referred to as a “crossing direction”.

図8は、上半身部分の水着1の基材が搬送方向に搬送される様子について説明する図であり、肩紐構成部材配置工程(S207)が実施された後の状態を表している。上半身部分の水着1をキャミソール型にする際に、上半身部分の水着1の左右方向の端部を構成する部分である切断箇所CLが設定され、この切断箇所CLを基準として各工程の動作が制御される。なお、切断箇所CLは搬送方向にP1の間隔(ピッチ)で設定される。この間隔P1は、前身頃10及び後身頃20の収縮前の横方向長さに相当する。   FIG. 8 is a diagram for explaining a state in which the base material of the swimsuit 1 in the upper body part is transported in the transport direction, and shows a state after the shoulder strap constituent member arranging step (S207) is performed. When the swimsuit 1 of the upper body part is made into a camisole type, a cutting point CL that is a part constituting the left and right ends of the swimsuit 1 of the upper body part is set, and the operation of each process is controlled based on this cutting part CL Is done. Note that the cutting points CL are set at an interval (pitch) of P1 in the transport direction. This interval P1 corresponds to the lateral length of the front body 10 and the back body 20 before contraction.

次に、接着領域形成機構210において、搬送された基材a上の後身頃20に該当する所定の領域にホットメルト型の接着剤を付着させて、接着領域を形成する(S202)。接着領域は、基材a上で切断箇所CLを挟んで搬送方向の両側に一対の接着領域を形成する。   Next, in the adhesion region forming mechanism 210, a hot melt adhesive is attached to a predetermined region corresponding to the back body 20 on the conveyed substrate a to form an adhesion region (S202). The adhesion region forms a pair of adhesion regions on both sides in the transport direction across the cut portion CL on the base material a.

続いて、弾性部材配置機構220において、複数の弾性部材23を搬送方向に伸長した状態で配置する(S203)。このとき、複数の弾性部材23の少なくとも一部の領域が接着領域と重なるように配置して、基材aに接着される。   Subsequently, in the elastic member arrangement mechanism 220, a plurality of elastic members 23 are arranged in an extended state in the transport direction (S203). At this time, it arrange | positions so that at least one part area | region of the some elastic member 23 may overlap with an adhesion | attachment area | region, and it adhere | attaches on the base material a.

そして、重ね合せ機構230において、基材aと複数の弾性部材23の上から基材bを重ね合わせる(S204)。これにより、複数の弾性部材23が厚さ方向において、基材aと基材bに挟み込まれた状態で固定される。   Then, in the superposition mechanism 230, the base material b is superposed on the base material a and the plurality of elastic members 23 (S204). Thereby, the some elastic member 23 is fixed in the state pinched | interposed into the base material a and the base material b in the thickness direction.

次に、弾性部材切断機構240において、隣接する切断箇所CL同士の間における中央部の弾性部材23を切断する。弾性部材切断機構240は、カッターとカッターを支持する部材が所定の動作を行うことで、所定箇所の弾性部材23を切断する。   Next, the elastic member cutting mechanism 240 cuts the elastic member 23 at the center between the adjacent cut portions CL. The elastic member cutting mechanism 240 cuts the elastic member 23 at a predetermined location by the cutter and the member supporting the cutter performing a predetermined operation.

そして、基材切断機構250において、基材a及び基材bから、前身頃10が連続してなる帯状前身頃10zと、後身頃20が連続してなる帯状後身頃20zに分離する。このとき、帯状前身頃10zと帯状後身頃20zを交差方向の長さが異なるように切断する。   Then, the base material cutting mechanism 250 separates the base material a and the base material b into a belt-like front body 10z in which the front body 10 is continuous and a belt-like back body 20z in which the back body 20 is continuous. At this time, the belt-like front body 10z and the belt-like back body 20z are cut so that the lengths in the crossing direction are different.

その後、肩紐構成部材接合機構260において、帯状前身頃10zと帯状後身頃20zとの間に架け渡すように、肩紐構成部材30を配置し、接合する(S207)。帯状前身頃10z及び帯状後身頃20zと肩紐構成部材30との接合は、ホットメルト接着剤等を用いて行われる。ホットメルト接着剤等で接合された領域が、肩紐固定部36である。図8に示すように、この状態の肩紐構成部材30には孔部38及び肩紐部35は形成されていない。なお、この工程において、肩紐構成部材30の長手方向の各端部を跨ぐように、それぞれ前身頃10、後身頃20(帯状前身頃10z、後身頃20z)の左右方向の長さが同じであるシート部材14、24を肌側から重ねてもよい。シート部材14、24を設けることで、着用時の肌触りを向上させることができる。   Thereafter, the shoulder strap constituting member joining mechanism 260 arranges and joins the shoulder strap constituting member 30 so as to be bridged between the belt-like front body 10z and the belt-like rear body 20z (S207). The joining of the belt-like front body 10z and the belt-like back body 20z and the shoulder strap constituting member 30 is performed using a hot melt adhesive or the like. A region joined by a hot melt adhesive or the like is a shoulder strap fixing portion 36. As shown in FIG. 8, the hole portion 38 and the shoulder strap portion 35 are not formed in the shoulder strap constituting member 30 in this state. In this step, the lengths of the front body 10 and the back body 20 (the belt-like front body 10z and the back body 20z) in the left-right direction are the same so as to straddle each end in the longitudinal direction of the shoulder strap component 30. A certain sheet member 14, 24 may be overlapped from the skin side. By providing the sheet members 14 and 24, the touch when worn can be improved.

次に、孔部切り抜き機構270において、肩紐構成部材30と帯状前身頃10zに孔部38を形成すると同時に、帯状前身頃10zに湾曲部16を形成する(S208)。図9は、図8の後、孔部38が形成された状態を説明する図である。孔部38は、肩紐構成部材30及び帯状前身頃10zを貫通した孔であり、孔部切り抜き機構270に設けられたカッターローラーとアンビルローラーとの間に挟み込んで通過させることで形成される。湾曲部16は、切断箇所CLを中心として搬送方向両側に設けられた半円形状からなり、孔部38を形成するカッターローラーとアンビルローラーを用いて、交差方向の外側に向けて窪ませることで形成される。このとき、交差方向において、孔部38の帯状前身頃10z側の端が、帯状前身頃10zの最も窪んだ部分uよりも帯状後身頃20z側に位置していることが好ましい。これによって、一定のテンションをかけた状態で搬送方向に帯状前身頃10zを搬送させた場合でも、孔部38の帯状前身頃10z側の端において裂け目が発生することを軽減することができるため、帯状前身頃10zを安定して搬送することができる。また、帯状前身頃10zと帯状後身頃20zを異なる形状とすることが好ましい。図9に示すように、帯状後身頃20zは、搬送方向に沿った辺は、搬送方向に略平行な辺のみを有するが、帯状前身頃10zは、交差方向の外側は搬送方向に略平行な辺を有し、交差方向の内側は切断箇所CLを中心として搬送方向両側に湾曲部16を有する。基材切断工程(S206)及び孔部切り抜き(S208)において、帯状前身頃10zと帯状後身頃20zの形状や大きさを異なるものにすることで、キャミソール型の上半身部分の水着1の前側と後側を認識しやすくすることができる。また、正面と背面とで身体の形状が異なる乳幼児の身体に応じた前身頃10と後身頃20の形状とすることができるため、乳幼児の身体に適した上半身部分の水着1とすることができる。   Next, in the hole cutout mechanism 270, the hole 38 is formed in the shoulder strap constituting member 30 and the belt-like front body 10z, and at the same time, the curved portion 16 is formed in the belt-like front body 10z (S208). FIG. 9 is a diagram for explaining a state in which the hole 38 is formed after FIG. The hole 38 is a hole penetrating the shoulder strap constituting member 30 and the belt-like front body 10z, and is formed by being sandwiched and passed between a cutter roller and an anvil roller provided in the hole cutout mechanism 270. The curved portion 16 has a semicircular shape provided on both sides in the conveying direction with the cutting point CL as the center, and is recessed toward the outside in the intersecting direction using a cutter roller and an anvil roller that form the hole 38. It is formed. At this time, in the crossing direction, it is preferable that the end of the hole 38 on the belt-shaped front body 10z side is located on the belt-shaped back body 20z side than the most depressed portion u of the belt-shaped front body 10z. Thereby, even when the belt-shaped front body 10z is transported in the transport direction in a state where a certain tension is applied, it is possible to reduce the occurrence of a tear at the end of the hole 38 on the belt-shaped front body 10z side. The belt-like front body 10z can be stably conveyed. Moreover, it is preferable that the belt-shaped front body 10z and the belt-shaped rear body 20z have different shapes. As shown in FIG. 9, the belt-like back body 20z has only sides that are substantially parallel to the transport direction, but the belt-like front body 10z is substantially parallel to the transport direction on the outside in the crossing direction. It has sides, and the inner side in the intersecting direction has curved portions 16 on both sides in the conveying direction with the cutting point CL as the center. In the base material cutting step (S206) and the hole cutout (S208), the front side and the rear side of the swimsuit 1 of the upper body part of the camisole type are made different in shape and size of the belt-like front body 10z and the belt-like back body 20z. The side can be easily recognized. Moreover, since it can be set as the shape of the front body 10 and the back body 20 according to the infant's body from which a body shape differs in the front and back, it can be set as the swimsuit 1 of the upper body part suitable for the infant's body. .

続いて、折り畳み機構280において、肩紐構成部材30を交差方向の中央部で折り畳み、帯状前身頃10zと帯状後身頃20zを厚さ方向において重ね合わせる(S209)。   Subsequently, in the folding mechanism 280, the shoulder strap constituting member 30 is folded at the center in the crossing direction, and the belt-like front body 10z and the belt-like back body 20z are overlapped in the thickness direction (S209).

重ね合された状態の帯状前身頃10zと帯状後身頃20zを、溶着機構290において、所定の領域を溶着して、接合部1Bを形成する(S210)。   A predetermined region is welded to the belt-like front body 10z and the belt-like back body 20z in a superposed state in the welding mechanism 290 to form the joint 1B (S210).

最後に、切り離し機構300において、切断箇所CLで帯状前身頃10zと帯状後身頃20zから前身頃10と後身頃20を切り離すことで(S211)、キャミソール型の上半身部分の水着1が形成される。   Finally, in the separation mechanism 300, the front body 10 and the back body 20 are separated from the belt-like front body 10z and the belt-like back body 20z at the cutting point CL (S211), and the swimsuit 1 of the upper body part of the camisole type is formed.

本実施形態では、肩紐構成部材接合機構260においてホットメルト接着剤を用いることで、前身頃10及び後身頃20と、肩紐構成部材30とをホットメルト接着剤で接合したが、これに限られない。肩紐構成部材接合機構260において、ヒートシール等の溶着又は圧着を行ってもよい。ホットメルト接着剤を用いて接合した場合、肩紐固定部36以外の部分にホットメルト接着剤を塗布すると、製造ラインの汚染や製造装置の不具合等を生じてしまったり、上半身部分の水着1が水に濡れるとホットメルト接着剤による接合部分が緩くなり、肩紐構成部材30が前身頃10又は後身頃20から離れてしまったりする恐れがある。これに対し、前身頃10及び後身頃20と、肩紐構成部材30とをヒートシール等によって接合することで、上半身部分の水着1が水に濡れても接合部が緩くなってしまう恐れをより軽減することができる。   In this embodiment, by using a hot melt adhesive in the shoulder strap constituent member joining mechanism 260, the front body 10 and the back body 20 and the shoulder strap constituent member 30 are joined by the hot melt adhesive. I can't. In the shoulder strap component joining mechanism 260, welding such as heat sealing or pressure bonding may be performed. In the case where the hot melt adhesive is used for bonding, if the hot melt adhesive is applied to a portion other than the shoulder strap fixing portion 36, the production line may be contaminated, the production apparatus may be damaged, or the swimsuit 1 on the upper body may be removed. When wetted with water, the joining portion by the hot melt adhesive becomes loose, and there is a possibility that the shoulder strap constituting member 30 may be separated from the front body 10 or the back body 20. On the other hand, by joining the front body 10 and the back body 20 and the shoulder strap constituting member 30 by heat sealing or the like, there is a risk that the joint will become loose even if the swimsuit 1 of the upper body part gets wet with water. Can be reduced.

===その他の実施の形態===
以上、本発明の実施形態について説明したが、上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。また、本発明は、その趣旨を逸脱することなく、変更や改良され得るとともに、本発明にはその等価物が含まれるのはいうまでもない。例えば、以下に示すような変形が可能である。
=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof. For example, the following modifications are possible.

上述の実施形態においては、弾性部材23、34は、糸ゴムを用いたが、これに限られない。伸縮シート等の他の弾性部材を用いてもよい。   In the above-described embodiment, the elastic members 23 and 34 are made of rubber thread, but are not limited thereto. Other elastic members such as an elastic sheet may be used.

また、上述の実施形態においては、後身頃20に弾性部材23を設けて、前身頃10に弾性部材を設けないことにしたが、これに限られない。前身頃10が備える糸ゴム等の弾性部材の数と後身頃20が備える弾性部材の数が異なるものとすることもできる。例えば、前身頃10に配置する糸ゴムの数を後身頃20に配置する糸ゴムの数より多くしても良い。乳幼児のように身体の前面と背面とで体型が大きくことなっていても、体型に応じてフィットさせやすくすることができる。   In the above-described embodiment, the elastic member 23 is provided on the back body 20 and the elastic member is not provided on the front body 10, but this is not a limitation. The number of elastic members such as rubber thread provided in the front body 10 may be different from the number of elastic members provided in the back body 20. For example, the number of thread rubbers arranged on the front body 10 may be made larger than the number of thread rubbers arranged on the back body 20. Even if the body shape is different between the front and back of the body like an infant, it can be easily fitted according to the body shape.

前身頃10が有する糸ゴム等の弾性部材の数と後身頃20が備える弾性部材の数が異なり、且つ、前身頃10が備える糸ゴムの数より後身頃20が備える糸ゴムの数の方が多いことがより好ましい。これによって、乳幼児のより身体の丸みを帯びた前面には、糸ゴムをより少なくした前身頃10によって伸縮力をより小さくすることで、乳幼児の前面に緩やかに沿わせ易くすることができる。一方、前面よりも平面的な背面には、糸ゴムをより多く配置して、乳幼児の背面にフィットさせ、上半身部分の使い捨ておむつ1の全体としても、乳幼児の胸部回りによりフィットさせることができる。この場合、前身頃10の左右方向に伸縮する弾性部材は、前身頃10の上部に配置せず、下部に配置することが好ましい。乳幼児の成長度合いによっては、胸囲が小さくて、前身頃10と乳幼児の前面との間に隙間を生じて、上半身部分の水着1の下部が身体から離れてしまう場合があるため、前身頃10及び後身頃20に設ける弾性部材の数を調整することで、乳幼児の体型に応じたフィット性を与えることができる。   The number of elastic members such as thread rubber included in the front body 10 is different from the number of elastic members included in the back body 20, and the number of thread rubbers included in the back body 20 is greater than the number of thread rubbers included in the front body 10. More is more preferable. As a result, it is possible to make the infant's front surface more round by making the elastic force smaller by the front body 10 with less rubber thread on the more rounded front surface of the infant. On the other hand, more rubber thread is arranged on the back surface that is flatter than the front surface to fit the back surface of the infant, and the entire disposable diaper 1 in the upper body part can be more closely fitted around the infant's chest. In this case, it is preferable that the elastic member that expands and contracts in the left-right direction of the front body 10 is not disposed in the upper part of the front body 10 but in the lower part. Depending on the degree of growth of the infant, the chest circumference is small and a gap is formed between the front body 10 and the front of the infant, and the lower part of the swimsuit 1 in the upper body part may be separated from the body. By adjusting the number of elastic members provided on the back body 20, it is possible to provide fit according to the body shape of the infant.

さらに、上述の実施形態においては、肩紐弾性部材34と後身頃20の弾性部材23とが厚さ方向で重なることにしたが、これに限られない。肩紐弾性部材34が前身頃10又は後身頃20に備えた左右方向に伸縮する弾性部材と厚さ方向で重なっていなくてもよい。また、前身頃10に弾性部材を備え、肩紐弾性部材34が前身頃10の弾性部材と重なるものであってもよいし、肩紐弾性部材34が、前身頃10の弾性部材と後身頃20の弾性部材23の両方と厚さ方向で重なるものであってもよい。肩紐弾性部材34と厚さ方向に重なる前身頃10の弾性部材の数や後身頃20の弾性部材23の数が多いほど、肩紐部35はより強固に前身頃10や後身頃20に固定することができる。   Furthermore, in the above-mentioned embodiment, although the shoulder strap elastic member 34 and the elastic member 23 of the back body 20 decided to overlap in the thickness direction, it is not restricted to this. The shoulder strap elastic member 34 does not have to overlap in the thickness direction with the elastic member that expands and contracts in the left-right direction provided in the front body 10 or the back body 20. Further, the front body 10 may be provided with an elastic member, and the shoulder strap elastic member 34 may overlap the elastic member of the front body 10, or the shoulder strap elastic member 34 may be the elastic member of the front body 10 and the back body 20. It may overlap with both the elastic members 23 in the thickness direction. The larger the number of elastic members of the front body 10 that overlap the shoulder strap elastic members 34 in the thickness direction and the number of elastic members 23 of the back body 20, the more firmly the shoulder strap portions 35 are fixed to the front body 10 and the back body 20. can do.

上述の実施形態においては、展開状態かつ伸長状態で、前身頃10と後身頃20の左右方向の長さは同じものとし、後身頃20に弾性部材23を備えることで、自然状態において、一対の接合部1Bが、上半身部分の水着1の後側に位置するようにしたがこれに限られない。予め接合部1Bを後側に設けるように各部材の寸法等を変更してもよい。例えば、前身頃10及び後身頃20にそれぞれ弾性部材を備え、前身頃10の左右方向の長さを後身頃20の左右方向の長さよりも長くする等してもよい。   In the above-described embodiment, the left and right lengths of the front body 10 and the back body 20 are the same in the unfolded state and in the stretched state. Although the joining part 1B is located on the rear side of the swimsuit 1 of the upper body part, it is not limited to this. You may change the dimension of each member, etc. so that the junction part 1B may be previously provided in the back side. For example, the front body 10 and the back body 20 may each be provided with an elastic member, and the length of the front body 10 in the left-right direction may be longer than the length of the back body 20 in the left-right direction.

また、上述の実施形態においては、一対の接合部1Bを備えた上半身部分の水着1であったが、これに限られない。例えば、接合部を1つ備え、前身頃と後身頃を1つの接合部で接合した後に、前身頃及び後身頃に肩紐を固定するものであってもよい。この場合、自然状態において、1つの接合部は、上半身部分の水着1の後側で、左右方向の中央部に設けていることが好ましい。これによって、接合部は、着用状態の着用者を正面から見た場合に、視認することができない場所に設けられているため、美観が向上する。また、一対の接合部1Bを設けた場合と同様に、他の部分よりも硬い接合部が背面に設けられているため、着用者が感じる違和感を軽減させることができる。   Moreover, in the above-mentioned embodiment, although it was the swimsuit 1 of the upper body part provided with a pair of junction part 1B, it is not restricted to this. For example, a single joint may be provided, and the shoulder straps may be fixed to the front body and the back body after the front body and the back body are joined by one joint. In this case, in a natural state, it is preferable that one joining portion is provided in the center portion in the left-right direction on the rear side of the swimsuit 1 of the upper body part. Thereby, since the junction part is provided in the place which cannot be visually recognized when seeing the wearer of a wearing condition from the front, aesthetics improve. Moreover, since the joining part harder than another part is provided in the back surface similarly to the case where a pair of joining part 1B is provided, the discomfort felt by the wearer can be reduced.

上述の実施形態においては、下半身部分の水着2に所謂3ピースタイプのパンツ型の使い捨ておむつを用いたがこれに限られない。所謂2ピースタイプのパンツ型の使い捨ておむつであってもよく、テープ型の使い捨ておむつであってもよい。また、必ずしも上半身部分の水着1と下半身部分の水着2をセットとして使用する必要はない。上半身部分の水着1のみを使用してもよい。   In the above-described embodiment, a so-called 3-piece type pants-type disposable diaper is used for the swimsuit 2 of the lower body part, but the present invention is not limited to this. It may be a so-called two-piece type pants-type disposable diaper or a tape-type disposable diaper. Moreover, it is not always necessary to use the swimsuit 1 of the upper body part and the swimsuit 2 of the lower body part as a set. Only the swimsuit 1 of the upper body part may be used.
