The skin side sheet member 21 is more skin side. The elastic member 23 is fixed by an adhesive or the like while being held between the two sheet members 21 and 22. Therefore, the rear body 20 is retractably attached to the back of the user in the left-right direction.

As shown in Fig. 2A and Fig. 4, the shapes of the front body 10 and the rear body 20 are different. Fig. 4 is a schematic view showing a configuration of a schematic plan view of Fig. 3A. In Fig. 4, the display of the elastic member 23 or the like is omitted from the vertical plan view of Fig. 2A. Both the front body 10 and the rear body 20 have a bilaterally symmetrical shape, but the rear body 20 is a rectangle having a length in the longitudinal direction longer than the length in the left and 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, by making the shapes of the front body 10 and the rear body 20 different, the user and the wearer can easily recognize the front side and the back side of the swimsuit 1 of the upper body part. In particular, the person wearing the object, that is, the infant, is in the process of starting self-growth, and has a situation in which he wants to wear the disposable swimsuit. Therefore, by having the front body 10 and the rear body 20 having different shapes, it is easy for the infant to distinguish the front side and the back side of the swimsuit 1 of the upper body part, and the infant can be easily worn by one person. Moreover, the general shape of infants and young children is that the ventral surface is more swell than the back. Therefore, by making the shapes of the front body 10 and the rear body 20 different, it is possible to create the swimsuit 1 suitable for the upper body portion of the infant body.

Further, the shape of the upper end 10f from one of the left and right directions of the front body 10 to the other is different from the shape of the upper end 20f from one of the left and right directions of the rear body 20 to the other, and the front body is easily recognized. 10 and the back of the body 20. That is, as shown in Fig. 2A and Fig. 4, the upper end 20f of the rear body 20 is a straight line along the left-right direction. For this, the upper end 10f of the front body 10 has the uppermost end located at the uppermost side ( The uppermost end of the front body is 10t, and the curved portion 16 bent inward from the uppermost end 10t toward the upper end of the side portion 10e and the neck portion 15 having a shape recessed from the uppermost end 10t toward the lower side. The curved portion 16 is formed in a shape that is curved toward the inside in order to allow the user's upper wrist to easily move in a wearing state. In general, since the human body performs an operation of moving the wrist forward, the bending portion 16 is provided, so that the motion of the user can be reduced. The neck portion 15 is a portion that covers the user's collar in a worn state. In the present embodiment, the neck portion 15 has a plurality of curved shapes, and the center portion in the left-right direction is located at the lowermost side, and the center portion in the left-right direction is located on the upper side toward the outer side, and the wear state is approximately V. Word shape. At this time, the upper end 10c of the center of the front body 10 in the left-right direction and the length Lc of the vertical direction between the upper end 10t and the uppermost end 10t are between the upper end 20c and the uppermost end 20t of the center of the rear body 20 in the left-right direction. The length in the up and down direction is longer. That is, as shown in Fig. 4, the upper end 10c of the center of the front body 10 in the left-right direction is located lower than the uppermost end 10t, so Lc is larger than 0. On the other hand, since the upper end 20c of the center of the rear body 20 in the left-right direction is almost the same as the position of the uppermost end 20t in the vertical direction, the length in the vertical direction is zero.

By making the shapes of the upper end 10f and the upper end 20f different, the infant and the like can more easily recognize the front side and the rear side of the swimsuit 1 of the upper body part. Further, by having a predetermined vertical length (Lc) between the upper end 10c and the uppermost end 10t in the center in the left-right direction, the collar can be made into a liberated shape in the worn state, so that the design can be improved. It can enhance the aesthetics of the user when they see it from the front.

Further, in the present embodiment, the upper end 10f of the front body 10 has the uppermost end 10t, the curved portion 16 and the neck portion 15, and the upper end 20f of the rear body 20 is formed in a straight line, but is not limited thereto. Both the upper end 10f and the upper end 20f may be linear, and only the plurality of curved portions may have a continuous shape. The front body 10 may not be the shape of the front body 10, and the central portion of the rear body 20 in the left-right direction may be recessed toward the lower side. The upper end 10f and the upper end 20f can be formed into arbitrary shapes.

As shown in FIGS. 2A and 4, the front body 10 is larger than the rear body 20. That is, the area of the front body 10 is larger than the area of the rear body 20. Further, in the up and down direction, the length (L10) of the longest portion of the front body 10 is longer (L10>L20) than the length (L20) of the longest portion of the rear body 20. As shown in Fig. 4, in the present embodiment, the length of the front body 10 in the up-and-down direction is the longest portion, and is a portion overlapping the shoulder-rope portion 35, from the lowermost end 10b located at the lowermost side of the front body 10 to The length in the vertical direction from the uppermost end (the uppermost end of the front body) 10 t at the uppermost side is L10. Since the length of the rear body 20 is almost constant, the length in the vertical direction from the lowermost end 20b located at the lowermost side of the rear body 20 to the uppermost end (the uppermost end of the rear body) 20t at the uppermost side is horizontal. The whole domain across the left and right direction becomes L20. Further, the lowermost end 10b of the front body 10 and the lowermost end 20b of the rear body 20 are substantially parallel straight lines in the left-right direction.

In the present embodiment, the lengths of the side portions 10e and the side portions 20e in the vertical direction are substantially the same. Therefore, as described above, in the case where the side portion 10e of the front body 10 and the side portion 20e of the rear body 20 are joined to form the swimsuit 1 of the upper body portion of the sling upper type, the length LM of the portion covering the collar at the time of wearing is applied. It is located above the upper end of the side portion 10e of the front body 10. In other words, when the positions of the lowermost end 10b of the front body 10 and the lowermost end 20b of the rear body 20 are the same in the vertical direction, the upper end 10t of the front body 10 is higher than the uppermost end 20t of the rear body 20. In the present embodiment, the difference between the longest portion (L10) of the front body 10 and the longest portion (L20) of the rear body 20 in the vertical direction is the length LM (L10 - L20 = LM).

By having such a front body 10 and a rear body 20, it is easier for an infant to recognize the front body 10 and the rear body 20. Further, one of the eyes of the swimsuit 1 of the upper body portion is adapted to fit the body shape of the infant by forming the front body 10 larger than the rear body 20 from the viewpoint of covering the chest of the user. The chest is covered.

Further, as shown in FIG. 2A, a plurality of elastic members 23 are provided in the rear body 20, but no elastic members are provided in the front body 10. That is, the rear body 20 is expanded and contracted in the left-right direction, but the front body 10 is hardly expanded and contracted in the left-right direction. Therefore, in the wearing state, when the user sees from the front, as shown in FIG. 1A, the wrinkles generated by the elastic member are hardly visually recognized in the swimsuit 1 of the upper body portion, but when the user sees it from the back, As shown in Fig. 1B, the swimsuit 1 in the upper body portion can visually confirm the plural wrinkles.

Fig. 5 is a view of the disposable swimsuit 100 in a worn state as seen from the side. In Fig. 5, the appearance of the infant in a worn state is seen from the right side, and the infant is raised with both hands upward. As shown in Fig. 5, the back surface of the infant is in a state of being appropriately bonded by the elastic member. On the other hand, since the front surface of the infant is not tightened by the elastic member, the front body 10 is only In the state of the body of the infant, it is the shape of the front of the infant.

Infants and young children, because the general abdomen is a shape that protrudes toward the front, the front is slightly rounder than the back, and the front abdomen is larger than the bust, and becomes a body that expands from the chest across the abdomen. For example, when the front body 10 is disposed with the elastic member in the same manner as the rear body 20, since the elastic member has a tendency to move toward the portion that is easily contracted, the elastic member is moved and contracted until the small chest bulging in the front of the body. The front body 10 is pulled upward in the upward direction until the chest rises, and the plurality of elastic members are concentrated in a narrow field and it is possible to excessively tighten the chest. In addition, when the front body 10 is provided with an elastic member, the lower portion of the front body 10 is easily pulled up in response to the movement of the infant, and even if the swimsuit 1 of the upper body portion is worn, the upper body of the infant may not be properly adapted. The covering and the pulled front body 10 may hinder the movement of the infant.

In this case, the swimsuit 1 of the upper body portion of the present embodiment is provided with the elastic member 23 in the rear body 20, and the front body 10 is not provided with the elastic member, and the front body 10 is pulled upward by the elastic member. The elastic members are concentrated toward the chest and do not shrink excessively. Further, in the worn state, the front body 10 not including the elastic member can have a portion that does not adhere to the body of the infant, so that the front body 10 can be pulled up by the movement of the infant, and the front body 10 can be lightened. The movement of the infant is restricted by the pulled front body 10. Thereby, the upper body portion of the infant can be appropriately covered, and the swimsuit 1 corresponding to the upper body portion of the shape of the body shape of the infant can be formed.

Further, the swimsuit 1 of the upper body portion is a pair of joint portions 1B in which the side portions 10e of the front body 10 and the side portions 20e of the rear body 20 are respectively joined in a natural state, and is the swimsuit 1 provided in the upper body portion. Back side. The "natural state" of the swimsuit 1 in the upper body portion is defined as follows. First, after the swimsuit 1 as the upper part of the packaged product is taken out from the package, the front body 10 and the rear body 20 are stretched toward the outside in the left-right direction, so that the front body 10 and the rear body 20 are different from each other. The monomers are uniform in size or elongated until they are near their length. After the stretched state is continued for 15 seconds, the stretched state of the swimsuit 1 in the upper body portion is released, and placed on a flat surface such as a table. Further, the state in which the state is 5 minutes after being placed in this plane is the natural state of the swimsuit 1 of the upper body portion.

Since the swimsuit 1 of the upper body portion does not have an elastic member in the front body 10 and the plurality of elastic members 23 are provided in the rear body 20, when the elastic member 23 is contracted in the natural state, the rear body 20 is shortened in the left-right direction. As a result, in the natural state, the front body 10 is placed on the lower side, the rear body 20 is placed on the upper side, and the pair of locking portions 1B are located on the upper side and the front body 10 is in a state of 5 minutes. (at least a part of the end portion in the left-right direction) is also located on the upper side.

When the swimsuit 1 of the upper body portion is worn, as shown in Fig. 5, the joint portion 1B is located on the back side of the user. The position of the joint portion 1B is more conspicuous than that of the swimsuit 2 of the lower body portion. The swimsuit 2 of the lower body portion is provided with an elastic member that expands and contracts in the left-right direction at both the front sill portion and the sac peripheral portion, and the joint portion 2B that joins the peripheral portion of the sac and the sac surrounding portion is located in front of the user and Almost the border on the back. That is, the joint portion 1B of the swimsuit 1 of the upper body portion is located on the rear side of the joint portion 2B of the swimsuit 2 of the lower body portion.

Since the joint portion 1B is located on the rear side, since the joint portion 1B is provided at a position where visual inspection is difficult, the user wearing the swimsuit 1 wearing the upper body portion can improve the appearance from the front when viewed from the front. Further, since the joint portion 1B is hardened by the joining by welding or the like, by providing the joint portion 1B on the back surface, it is possible to further reduce the arrangement of the joints which are more likely to move under the front surface and the side surface (under the armpit) of the body. The feeling of the user's wearing when the part 1B is felt.

Further, as shown in FIG. 4 and the like, the most concave portion of the neck portion 15 is provided at the center portion in the left-right direction, and the lowermost end portion 15b of the portion recessed at the lowermost side is located at the lowermost side of the upper end 10f of the front body 10. section. The lowermost end 15b is preferably located above the upper end of the joint portion 1B of the swimsuit 1 of the upper body portion of the suspender upper garment type. That is, it is preferable that the upper end 10f of the front body 10 does not have a portion located lower than the upper end of the joint portion 1B. The swimsuit 1 of the upper body portion of the sling top type is in the extended state, and the lowermost end 15b of the neck portion 15 is higher than the elastic member 23. Since the front body 10 and the rear body 20 are connected in a ring shape by the locking portion 1B and the other side locking portion 1B on one side in the left-right direction, the stretching force is actuated during wearing and wearing. Between the pair of locking portions 1B. Here, when the lowermost end 15b of the neck portion 15 is located below the upper end of the joint portion 1B, the lowermost end 15b of the neck portion 15 is easily broken as a starting point of the neck portion 15 by the tensile force. At this point, by providing the lowermost end 15b of the neck portion 15 above the upper end of the joint portion 1B, it is possible to reduce the possibility that the lowermost end 15b of the neck portion 15 becomes the starting point of the breakage.

Further, as shown in FIG. 2A, the end portion of the shoulder cord elastic member 34 of the shoulder cord portion 35 on the rear body 20 side overlaps with the elastic member 23 of the rear body 20 in the thickness direction. Thereby, for example, even if the shoulder rope elastic member 34 is strongly pulled in the up and down direction, the shoulder rope elastic member 34 is excessively elongated, and the elastic member 23 of the rear body 20 overlapping the shoulder rope elastic member 34 is elongated in the left-right direction. Therefore, it is possible to reduce the elongation of the shoulder elastic member 34 in the up-and-down direction. Therefore, it is possible to reduce the possibility that the shoulder cord portion 35 is broken by the elongation in the up-and-down direction or separated from the rear body 20, and the fixation between the shoulder cord constituent member 30 and the rear body 20 can be made stronger.

In addition to the basic configuration of the swimsuit 1 of the upper body part, a decoration such as a ruffle may be added. Since the person wearing the object is mainly a daughter, it is possible to attract the concern of the user or the like by adding a cute decoration or the like. For example, a lotus leaf edge (not shown) having a plurality of pleats may be provided in the front body 10 and the rear body 20. At this time, the number of pleats provided on the front flap side of the front body 10 and the number of pleats provided on the rear flap side 20 of the rear body 20 may be different. By having a plurality of burrs having different pleats, it is easy for an infant to recognize the front side and the back side of the swimsuit 1 of the upper body portion.

Further, the number of pleats of the front ruffles is more preferably than the number of pleats of the back ruffles. By providing more pleats on the front side, it is possible to enhance the aesthetics of the user when viewed from the front. Moreover, it is easier for the infant to recognize the front side and the back side of the swimsuit 1 of the upper body part.

And only the front ruffle edge is set, and the back ruffle is not set. By providing the ruffles on at least the front side, it is possible to enhance the aesthetics of the user when viewed from the front.

Moreover, the decoration added to the swimsuit 1 of the upper body part is not limited to the lotus leaf side. It is suitable to add patterns, sequins, rhinestones, etc. to make infants happy to decorate.

Moreover, the number of materials that are overlapped in the thickness direction of the shoulder cord portion 35 of the swimsuit 1 in the upper body portion is more preferably than the number of materials that are overlapped in the thickness direction of the front body 10 and the rear body 20. The length of the shoulder cord portion 35 is shorter than the front body 10 and the rear body 20, and the portion in which the force in the vertical direction is applied is often caused by the user's movement or the like during wearing and wearing. So it becomes easy to break. Therefore, by making the number of materials that are overlapped in the thickness direction of the shoulder cord portion 35 larger, the possibility that the shoulder cord portion 35 is broken can be further reduced.

In order to reduce the possibility of breakage of the shoulder cord portion 35, it is preferable that the end portions of the one outer sheet 33 in the left-right direction are folded back toward the skin side. Further, it is preferable to position the film on the folded portion of the outer sheet 33. In the above-described embodiment, as shown in Fig. 3B, the outer sheet 33, the back sheet 32, and the outer sheet 33 are sequentially superposed from the skin side, whereby the rigidity can be further improved. Further, the shoulder cord portion 35 is provided with a back sheet 32 composed of a liquid-impermeable film sheet such as a polyethylene film and a polypropylene film which are higher in rigidity than the outer sheet 33, thereby reducing the shoulder line portion. 35 damage.

Further, the shoulder cord portion 35 is provided with a shoulder cord elastic member 34, and the shoulder cord portion 35 is provided with stretchability in the vertical direction. The shoulder cord portion 35 is prevented from being damaged by the rigidity of the shoulder cord elastic member 34, and can be adjusted to be stretched and contracted in accordance with the size of the user's body.

Further, in the present embodiment, the one shoulder strap constituent member 30 includes a pair of shoulder strap portions 35, and the shoulder cord portion 35 on one side and the shoulder strap portion 35 on the other side are connected by the shoulder strap fixing portion 36. The composition, but is not limited to this. The shoulder cord portion 35 on one side and the shoulder cord portion 35 on the other side may be separated. Thereby, since the shoulder line part 35 of arbitrary shape can be provided in arbitrary places, the feeling of the swimsuit 1 of the upper body part, and pattern designability can be improved. However, the one shoulder rope constituting member 30 is provided with a pair of shoulder cord portions 35, and the shoulder cord portion 35 on one side and the shoulder cord portion 35 on the other side are connected by the shoulder cord fixing portion 36, and The shoulder cord fixing portion 36 is wider, and the joint strength between the shoulder cord portion 35 and the front body 10 or the rear body 20 can be further improved.

=== Manufacturing method of the disposable swimsuit 1 for the upper body part === Next, a method of manufacturing the swimsuit 1 of the upper body portion will be described. Fig. 6 is a flow chart showing the processes in the manufacture of the disposable swimsuit 1 for the upper body portion. Fig. 7 is a view for explaining a manufacturing apparatus 200 manufactured by the disposable swimsuit 1 in which the upper body portion is used.

As shown in Fig. 6, the swimsuit 1 of the upper body portion is conveyed via the substrate (S201), the adhesive region (S202), the elastic member (S203), the substrate (S204), and the elastic member. (S205), substrate cutting (S206), shoulder rope constituent member arrangement (S207), hole portion cutting (S208), substrate folding (S209), welding (S210), and substrate cutting (S211) The process is formed.

Hereinafter, each process will be described with reference to the manufacturing apparatus 200. In the manufacturing apparatus 200 shown in Fig. 7, the swimsuit 1 of the upper body portion is continuously manufactured by performing the above-described respective processes (S201 to S211). The manufacturing apparatus 200 includes a transport mechanism 201, an adhesive field forming mechanism 210, an elastic member disposing mechanism 220, an overlapping mechanism 230, an elastic member cutting mechanism 240, a substrate cutting mechanism 250, and a shoulder cord. The member joining mechanism 260, the hole cutting mechanism 270, the folding mechanism 280, the welding mechanism 290, and the cutting mechanism 300.

First, the base material a(b) (hereinafter simply referred to as "base material") of the swimsuit 1 of the upper body portion is transported by a predetermined transport speed by the transport mechanism 201. 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 connected in parallel in the vertical direction. The strip-shaped member continuous in the left-right direction, the base material a is a strip-shaped sheet member in which the non-skin side sheet member is continuous, and the base material b is a strip-shaped sheet member in which the skin-side sheet member is continuous. In addition, the "transport direction" refers to the direction along the left-right direction of the front body 10 and the rear body 20 in Fig. 2A. In the following description, the direction intersecting the conveyance direction (that is, the direction along the vertical direction of the front body 10 and the rear body 20) is also referred to as "cross direction".

FIG. 8 is a view showing a state in which the base material of the swimsuit 1 in the upper body portion is conveyed in the conveyance direction, and shows a state in which the shoulder rope constituent member arrangement process (S207) is performed. When the swimsuit 1 of the upper body portion is formed into a sling top type, the portion of the end portion of the swimsuit 1 that constitutes the upper body portion in the left-right direction, that is, the cut portion CL is set, and the operation of each process is controlled based on the cut portion CL. . Further, the cut portion CL is set in the conveyance direction by the interval (pitch) of P1. This interval P1 is equivalent to the lateral length of the front body 10 and the rear body 20 before contraction.

Next, in the adhesive region forming mechanism 210, a heat-fusible adhesive is adhered to a predetermined region of the rear body 20 on the substrate a to be conveyed to form an adhesive region (S202). In the adhesive field, a pair of adhesive fields are formed on the substrate a and on both sides of the conveyance direction in which the cut portion CL is held.

Next, in the elastic member disposing mechanism 220, the plurality of elastic members 23 are placed in a state of being elongated in the conveyance direction (S203). At this time, the field of at least a part of the plurality of elastic members 23 is adhered to the substrate a in an overlapping manner with the adhesive region.

Further, in the overlapping mechanism 230, the base material b is superposed on the base material a and the plurality of elastic members 23 (S204). Thereby, the plurality of elastic members 23 are fixed in the thickness direction and are held by the base material a and the base material b.

Next, in the elastic member cutting mechanism 240, the elastic member 23 at the center portion between the adjacent cut portions CL is cut. The elastic member cutting mechanism 240 cuts the predetermined elastic member 23 by performing a predetermined operation on the member that supports the cutter and the cutter.

Further, in the substrate cutting mechanism 250, the substrate a and the substrate b are separated into a strip-shaped front body 10z in which the front body 10 is continuous and a belt-shaped rear body 20z in which the rear body 20 is continuous. At this time, the length of the belt-shaped front body 10z and the belt-shaped rear body 20z in the intersecting direction is different.

Thereafter, the shoulder-rope constituting member 30 is placed between the belt-shaped front body 10z and the belt-shaped rear body 20z so as to be placed between the belt-like front body joining mechanism 260 (S207). The joining between the belt-shaped front body 10z and the belt-shaped rear body 20z and the shoulder-rope constituent member 30 is performed using a heat fusion adhesive or the like. A field joined by a heat fusion adhesive or the like is a shoulder cord fixing portion 36. As shown in Fig. 8, the hole portion 38 and the shoulder cord portion 35 are not formed in the shoulder cord constituent member 30 in this state. Moreover, in this process, the front body 10 and the rear body 20 (the belt front body 10z and the rear body 20z) are respectively oriented in the left-right direction so as to straddle the respective end portions of the shoulder rope constituting member 30 in the longitudinal direction. The sheet members 14 and 24 having the same length may be overlapped from the skin side. By providing the sheet members 14, 24, the feeling of muscle touch at the time of wearing can be improved.

Next, in the hole portion cutting mechanism 270, the hole portion 38 is formed in the shoulder cord constituent member 30 and the belt-shaped front body 10z, and the curved portion 16 is formed in the belt-shaped front body 10z (S208). Fig. 9 is a view for explaining a state in which the hole portion 38 is formed after the eighth drawing. The hole portion 38 is a hole that penetrates the shoulder rope constituting member 30 and the belt-shaped front body 10z, and is formed by being inserted between the cutter roller and the anvil roller provided in the hole portion cutting mechanism 270. . The curved portion 16 is formed by a semicircular shape provided on both sides in the conveyance direction around the cut portion CL, and the cutter roller and the anvil roller forming the hole portion 38 are recessed toward the outer side in the intersecting direction. form. At this time, in the intersecting direction, the end of the belt-shaped front body 10z side of the hole portion 38 is preferably located on the side of the body 20z more than the most concave portion u of the belt-shaped front body 10z. By this means, even if the belt-shaped front body 10z is conveyed in the conveyance direction in a state where a certain stretch is applied, since the split slit is formed at the end of the belt-shaped front body 10z side of the hole portion 38, it is possible to The belt front body 10z is stably carried. Further, it is preferable that the belt-shaped front body 10z and the belt-shaped rear body 20z are formed in different shapes. As shown in Fig. 9, the belt-shaped rear body 20z has a side substantially parallel to the conveyance direction along the side in the conveyance direction, but the belt-shaped front body 10z has an outer side in the intersecting direction which is substantially parallel to the conveyance direction. The inner side in the intersecting direction has a curved portion 16 on both sides in the conveying direction around the cut portion CL. In the substrate cutting process (S206) and the hole cutting (S208), the upper body portion of the sling upper type can be easily recognized by different shapes and sizes of the belt-shaped front body 10z and the belt-shaped rear body 20z. The front side and the back side of the swimsuit 1. Further, since the shape of the front body 10 and the rear body 20 of the body of the infant having different shapes of the body of the front and back can be made, the swimsuit 1 suitable for the upper body portion of the body of the infant can be prepared.

Next, in the folding mechanism 280, the shoulder cord constituent member 30 is folded from the center portion in the intersecting direction, and the belt-shaped front body 10z and the belt-shaped rear body 20z are overlapped in the thickness direction (S209).

In the welding mechanism 290, the belt-shaped front body 10z and the belt-shaped rear body 20z are welded together to form a joint portion 1B (S210).

Finally, in the cutting mechanism 300, the upper body portion 10 and the rear body 20 are cut away from the belt-shaped front body 10z and the belt-shaped rear body 20z at the cutting portion CL (S211), thereby forming the upper body portion of the sling top type. Swimsuit 1.

In the present embodiment, the shoulder body constituent member joining mechanism 260 is joined by the heat fusion adhesive by using the heat fusion adhesive, but the front body 10 and the rear body member 30 and the shoulder cord constituent member 30 are joined by the heat fusion adhesive. In the shoulder cord constituting member joining mechanism 260, welding or press fitting by thermocompression sealing or the like may be performed. In the case of bonding with a heat-adhesive adhesive, if the heat-adhesive adhesive is applied to a portion other than the shoulder-line fixing portion 36, contamination of the production line and problems of the manufacturing apparatus may occur, and the swimsuit 1 of the upper body portion is adhered by heat fusion. The joint portion produced by the agent is loosened, and the shoulder cord constituent member 30 may be separated from the front body 10 or the rear body 20. In this case, by joining the front body 10 and the rear body 20 and the shoulder cord constituting member 30 by heat sealing or the like, the swimsuit 1 of the upper body portion can be more loosened of the joint portion even if it is wet.

=== OTHER EMBODIMENT === The above description of the present embodiment has been described, but the above-described embodiments are merely for the purpose of facilitating the understanding of the present author and are not intended to limit the author. Moreover, this creation can be changed and improved without departing from its purpose, and the creation also includes its equivalent. For example, the following modifications can be made.

In the above-described embodiment, the elastic members 23 and 34 are rubber cords, but are not limited thereto. It is also possible to use other elastic members such as a stretch sheet.

And in the above-described embodiment, the elastic member 23 is provided in the rear body 20, and the elastic member is not provided in the front body 10, but is not limited thereto. The number of elastic members such as rubber threads provided in the front body 10 and the number of elastic members provided in the rear body 20 may be different. For example, the number of rubber wires disposed in the front body 10 may be larger than the number of rubber wires disposed in the rear body 20. Even if the body shape of the front and back of the body of the infant is very different, it can be easily fitted to the body type.

The number of elastic members such as rubber threads of the front body 10 and the number of elastic members provided in the rear body 20 are different, and the number of rubber threads provided in the rear body 20 is higher than that of the front body 10. The number of lines is much better. Thereby, in the front of the more rounded body of the infant's body, the telescopic force is further reduced by further reducing the front body 10 of the rubber thread, and the front side of the infant can be easily relaxed. On the other hand, in the back surface which is flatter than the front side, the rubber thread is disposed more so that it fits on the back of the infant, and the upper part of the disposable diaper 1 can be more closely attached to the infant. Around the chest. In this case, the elastic member that expands and contracts in the left-right direction of the front body 10 is preferably disposed not in the upper portion of the front body 10 but also in the lower portion. Depending on the degree of growth of the infant, if the chest circumference is small and there is a gap between the front body 10 and the front of the infant, the lower part of the swimsuit 1 of the upper body part is placed away from the body, and is adjusted by the front body 10 and the rear. The number of elastic members of the body 20 can be given to the fit of the body shape of the infant.

Further, in the above-described embodiment, the shoulder elastic member 34 and the elastic member 23 of the rear body 20 are overlapped in the thickness direction, but are not limited thereto. The shoulder cord elastic member 34 may be an elastic member that expands and contracts in the left-right direction provided in the front body 10 or the rear body 20, and may not overlap in the thickness direction. Further, the front body 10 is provided with an elastic member, and the shoulder elastic member 34 is overlapped with the elastic member of the front body 10. The shoulder elastic member 34 is an elastic member for the front body 10 and the elastic member 23 of the rear body 20. Both sides can overlap in the thickness direction. The more the number of elastic members of the front body 10 and the number of the elastic members 23 of the rear body 20 overlapping with the shoulder elastic member 34 in the thickness direction, the shoulder rope portion 35 can be more strongly fixed to the front body 10 and the rear body 20.

In the above-described embodiment, in the expanded state and in the extended state, the lengths of the front body 10 and the rear body 20 in the left-right direction are the same, and by providing the elastic member 23 in the rear body 20, in a natural state, a pair of joints The portion 1B is the rear side of the swimsuit 1 located in the upper body portion, but is not limited thereto. The size or the like of each member may be changed so that the pre-joining portion 1B is provided on the rear side. For example, the front body 10 and the rear body 20 are each 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 rear body 20 in the left-right direction.

Further, in the above-described embodiment, the swimsuit 1 including the upper body portion of the pair of joint portions 1B is not limited thereto. For example, one of the joint portions may be provided, and the front body and the rear body may be joined to each other by the one joint portion, and the shoulder line may be fixed to the front body and the rear body. In this case, in the natural state, one joint portion is preferably provided on the rear side of the swimsuit 1 in the upper body portion, and is provided in the center portion in the left-right direction. Therefore, when the user in the wearing state is seen from the front, the joint portion is provided in a place where it is not visually identifiable, so that the appearance can be improved. Further, similarly to the case where the pair of joint portions 1B are provided, since the joint portion which is harder than the other portions is provided on the back surface, it is possible to reduce the user's feeling of strangeness.

In the above-described embodiment, the swimsuit 2 of the lower body portion is a disposable diaper of the type which is a pant type, but is not limited thereto. A disposable diaper of the type of panty type may be used, and a disposable diaper of the belt type may be used. Further, it is not always necessary to use the swimsuit 1 of the upper body portion and the swimsuit 2 of the lower body portion as a suit. Only the swimsuit 1 using the upper body part is also acceptable.
