The shoulder strap 15 may be wide over the entire length.

  The urethane molded body 2 provided in the cup portion 10 is formed by molding polyurethane foam. As shown in FIG. 5, the urethane molded body 2 has a curved surface (a saddle shape) protruding outward so that the breast B can be accommodated therein, and the most protruding portion of the curved surface is A layer thickness portion 23 is formed by increasing the thickness of the foam below the curved surface that accommodates the breast portion B as the top portion 25. For example, in this embodiment, the thickness dimension E of the layer thickness portion 23 is 15 mm to 25 mm. And the top part 25 is formed so thin that it can accommodate the nipple P. Furthermore, the upper portion of the cup portion 10 that accommodates the breast portion B forms an upper cup portion 27 having a layer thickness that is thinner than the layer thickness portion 23 of the lower portion.

The lower end edge of the urethane molded body 2 forms a support portion 30 having a high density by compressing polyurethane foam with a high pressure. As shown in FIG. 2, the support portion 30 extends from the position where the coupler 13 is disposed to the side portion 34. The support portion 30 is formed in a belt shape having a predetermined width. For example, in this embodiment, the width S (see FIG. 3) of the support portion 30 is 4 to 9 mm (more preferably 4 to 5 mm), and the layer thickness is 1.0 to 2.0 mm.
Moreover, the upper edge part 33 of the urethane molded body 2 which becomes the upper end edge of the upper cup part 27 of the cup part 10 is formed by compressing polyurethane foam to be partially thin. The support part 30 and the upper end edge part 33 do not have elasticity in the width direction and the length direction, and have high shape retention.

Then, the inner part (the connecting part side) of the lower part of the cup surrounded by the lines X, Y and the support part 30 is the inner part of the cup lower part 23A, and the outer part of the lower part of the cup surrounded by the line X, the line A and the support part 30 (rear surface). The part on the cloth attachment side) is the cup lower outer side 23B, the part inside the cup upper part surrounded by the line X and line Y and the upper edge part 33 is the cup upper inner part 27C, the line X and line Y, the support part 30 and the upper end. When the outer part of the upper part of the cup surrounded by the edge 33 is the upper part 27D of the upper part of the cup, the layer thickness part 23 extends from the inner part 23A of the lower part of the cup and the outer part 23B of the lower part of the cup. The layer thickness is gradually reduced toward the portion 35. Then, the portion closer to the top portion 25 of the layer thickness portion 23 continues to the center point O via the inclined portion 251, and the opposite portion continues to the support portion 30.
Further, the upper cup portion 27 having a urethane layer thickness thinner than the layer thickness portion 23 extends from the cup upper inner side 27C to the shoulder strap attaching portion 35 of the upper outer side 27D, and extends from the cup upper inner side 27C to the upper outer side 27D. The thickness is gradually increased to continue to the layer thickness portion 23 of the cup upper outer side 27D, and the layer thickness is gradually decreased toward the upper end edge portion 33 and the shoulder strap attachment portion 35, and the top portion 25 side is an inclined portion. It continues to the center point O via H.251.

Here, the manufacturing method of the cup part 10 is demonstrated. ... See FIG. 6 The urethane molded body 2 housed in the cup part 10 is molded by stacking at least three urethane foams having a layer thickness of about 5 mm including the urethane foam to which the inner cloth 11 is bonded.
First, the inner cloth 11 is bonded to the first urethane foam 2a. ... Figure 6 (1)
The first urethane foam 2a is a material having a property that the melted surface 20a is gelatinized by thermally melting the surface with a gas burner or the like (for example, “Achilles Aeron BA” manufactured by Achilles Co., Ltd.), The inner cloth 11 is pressure-bonded to the melting surface 20a, and the inner cloth 11 is bonded to the first urethane foam 2a.
However, the method is not limited to this method, and a paste-like material may be applied to normal urethane foam and the inner cloth 11 may be bonded or stitched. However, the method of bonding to the gelatinized molten surface is more durable. Is more preferable in terms of property and shape retention.

A urethane foam laminate is formed. ... Figure 6 (2)
The 2nd urethane foam 2b is piled up on the surface where the inner cloth 11 of the 1st urethane foam 2a is not stuck, making the surface where inner cloth 11 is stuck down.
The auxiliary urethane foam 2c is placed on the second urethane foam 2b.
The auxiliary urethane foam 2c is an arc-shaped article, and is a urethane foam having a mountain shape in which the arc peripheral portion 400 is thinned and the layer thickness is gradually increased toward the central portion 500.
The third urethane foam 2d is overlaid on the auxiliary urethane foam 2c.
The second and third urethane foams 2b and 2d and the auxiliary urethane foam 2c may be general urethane foams.

FIG. 6 (3) shows a state in which the urethane foams are stacked. This figure is displayed in parallel corresponding to each part of the cup part for convenience of explanation.
The portions where only the first urethane foam 2a, the second urethane foam 2b, and the third urethane foam 2d are polymerized (places not through the auxiliary urethane foam 2c) are the support portion 30, the cup upper inner side 27C, and the upper end. The edge portion 33 and the cup upper outer side (a portion excluding the layer thickness portion, the vicinity of the string attaching portion) 27D (see FIG. 3) are formed. The height of the laminated foam (original foam thickness) is 15 mm.
The height (original foam thickness) of the portion where the thin arc peripheral portion 400 of the auxiliary urethane foam 2c is laminated at the portion where the auxiliary urethane foam 2c is laminated is 20 mm, and the thickness of the auxiliary urethane foam 2c gradually increases. In the vicinity where the height of the laminated body (original foam thickness) is 29 mm, a cup lower inner side 23A is formed. The height (original foam thickness) of the portion where the thickest portion of the auxiliary urethane foam 2c is laminated is 34 mm, and this vicinity forms the cup lower outer side 23B. The height of the middle part (original foam thickness) is 30 mm and this part forms the top 25 of the cup.

Mold processing. ... Fig. 6 (4)
A laminated urethane foam (the thickest thickness is 34 mm, the thinnest thickness is 15 mm, and the density is 25 kg / m ³ ) is molded by the lower hook 200A and the upper hook 200B having an uneven surface having a desired shape. By this processing, the entire cup is compressed so as to be in a compressed state.
Processing conditions: Lower pot 175 ° C, upper pot 170 ° C, mold time 220 seconds.
By this molding, each part is compressed as shown in the following table.

  That is, the portion corresponding to the support portion 30 is compressed from the original foam thickness of 15 mm to 1.0 to 2.0 mm and to 1/15 to 2/15 of the original foam thickness. And cup upper outer side 27D (a part except a layer thickness part, the string attachment part vicinity) is compressed by 2/5-3/5 from 15 mm of original foam thickness to 6-9 mm. The cup upper inner side 27C is compressed to 15 to 4 to 5 mm from the original foam thickness to about 1/3 of the original foam thickness. The upper end edge 33 of the upper cup portion 27 is compressed from the original foam thickness of 15 mm to 1.0 to 1.5 mm and to 1/15 to 1/10 of the original foam thickness. The cup lower inner side 23A is compressed to about 5/10 from the original foam thickness of 29 mm to 15 mm. The top 25 of the cup part is compressed from 1/6 to 3/10, from the original foam thickness of 30 mm to 5-9 mm. The cup lower outer side 23B is compressed to about 6/10 to 7/10, with the original foam thickness from 34 mm to 22 mm.

  Thus, the support part 30 compressed to 1.0 to 2.0 mm (1/15 to 2/15) from the layer thickness of 15 mm has a high density and does not have elasticity and stretchability. For this reason, a shape maintenance characteristic becomes large. The cup upper outer portion 27D (the portion excluding the layer thickness portion, the vicinity of the string attachment portion) compressed to a thickness of 15 mm to 6 to 9 mm (2/5 to 3/5) has a thin layer thickness and a slightly higher density, Compared to the support portion 30, it has elasticity and flexibility. The cup upper inner side 27 </ b> C that is compressed from the original foam thickness of 15 mm to 4 to 5 mm to about 1/3 of the foam original thickness has a thin layer thickness and a high density, but has elasticity and flexibility as compared with the support portion 30. The upper end edge portion 33 of the upper cup portion 27 having a layer thickness of 15 mm compressed to 1.0 to 1.5 mm (1/15 to 1/10) has a higher density, but the compression rate decreases as the top portion 25 is approached. Therefore, it has elasticity and flexibility compared to the support portion 30 in which all the predetermined widths are high density. The portion compressed from 29 mm to 15 mm (about 5/10) and 34 mm to 22 mm (about 6/10 to 7/10), the cup lower inner side 23A and the cup lower outer side 23B are adjusted to the density of the original foam. Close and elastic. And the top part 25 compressed from 5 mm to 9 mm (1/6 to 3/10) from a thickness of 30 mm has elasticity and good shape retention.

A brassiere is formed by laminating the outer cloth 12 on the urethane molded body 2 formed as described above.
Next, molding of the outer cloth 12 will be described.
The outer cloth 12 is molded. ... Figure 7
The outer cloth (fabric) 12 is molded by the lower hook 250A and the upper hook 250B having an uneven surface having a curvature that becomes the curved outer surface of the cup portion.
Mold processing conditions: Lower pot (250A) 160 ° C, Upper pot (250B) 165 ° C,
Molding time 60 seconds By this molding process, the outer cloth 12 is formed into a curved surface similar to the curved surface of the cup portion.

  The outer cloth 12 that has been processed into a curved surface is laminated (coated) on the outer surface of the urethane molded body 2 to which the inner cloth 11 is adhered. Thereafter, as shown in FIGS. 4 and 5, the periphery of the cup is covered with covering cloths (stretchable tapes) 120 and 122, and the back cloth 17 is continuously provided. Further, the bra 100 is formed by connecting one end of the shoulder strap 15 to the shoulder strap attaching portion 35 of the cup portion 10 and connecting the other end to the back cloth 17. At this time, by connecting the other end of the shoulder strap 15 closer to the center portion of the back cloth 17, the load applied to the shoulder can be dispersed by the wide portion of the shoulder contact portion, the comfort is facilitated, and It is possible to prevent the shoulder strap 15 from slipping off.

The brassiere 100 is a method in which only the outer cloth 12 is laminated on the urethane molded body 2, but the color of the urethane molded body may change to yellow over time. When the color of the brassiere is light, for example, in the case of a brassiere such as beige or white, the discolored yellow color of the urethane molded body is visible from the appearance. When there is such a concern, an intermediate fabric (for example, a mesh fabric of 100% nylon) is interposed between the urethane molded body 2 and the outer fabric 12. This intermediate fabric is also molded separately from the urethane molded body and the outer fabric to form a curved surface and then laminated.
The mold processing conditions for this intermediate fabric are:
Mold processing conditions: Lower pot 165 ° C., upper pot 160 ° C., mold time 40 seconds.
A urethane molded body, an intermediate cloth, and an outer cloth are laminated, and a brassiere is formed by ending the periphery of the cup with a covering cloth (stretchable tape).

Thus, since the inner cloth 11 is bonded to the urethane molded body 2 on the inner surface of the brassiere 100 (the surface that comes into contact with the skin when worn), the inner cloth 11 is a cup. Following the shape of the bag, there is no looseness and the comfort is improved, and the fastness to washing is improved. Further, the top portion 25 having a high shape retaining property is provided in the portion that accommodates the nipple P, and the thickness of the urethane layer is increased at a lower portion around the top portion 25 at a low compression rate, thereby forming a layer thickness portion 23 having elasticity. Therefore, the breast part B accommodated on the inner surface is lifted by the cup lower outer side 23B with the thickened urethane layer at the lower part of the breast, and the side part of the breast part B has the cup lower outer side 23B with the thickened urethane layer thickness. At the upper cup outer side 27D, as shown by an arrow H in FIG. Further, as shown in FIG. 2, the layer thickness portion 23 of the lower inner side 23 </ b> A lifts the breast portion B from the lower portion as indicated by an arrow I, and the upper end edge portion 33 of the upper cup portion 27 is flexible because the layer thickness is thin. It can follow the movement of the wearer, such as the vertical movement of the arm, and the movement of the contained breast, and does not lift from the breast B of the upper cup. Further, the breast part B lifted by the cup part lower outer side 23B can be accommodated without being crushed. Furthermore, since the breast part B contacts the whole surface of the layer thickness part 23 of the cup part 10, and is lifted by surface compression, a feeling of wear becomes favorable.
Even if the breast part B is not large, the lower part of the cup is corrected by the layer thickness part 23, the upper part is corrected by the upper cup part 27, and the nipple part P is accommodated in the top part 25. Therefore, the outer shape of the bust portion is adjusted, and a volume increase effect is obtained.
Further, the lower side of the breast part B supports the lower part of the breast part B without extending and contracting from the position where the coupling tool 13 is placed to the side part in addition to the lifting effect of the layer thickness part 23, and the wire Even if the layer is not disposed, the lower part of the breast B is reliably lifted upward by the surface contact by the layer thickness part 23 and the support part 30 without a feeling of pressure. Moreover, since the contact area is large, there is little movement of the cup part by the movement of the body.

As described above, the brassiere 100 of the present invention can achieve reliable bust-up, volume-up, and bust correction, even in the case of wireless, regardless of the presence or absence of a wire. In addition, the lower cup part has no squeezing, and the breast shape is adjusted comfortably and securely in the lifting / supporting of the bust part by extensive surface contact between the layer thickness part 23 and the support part 30, and the bust up / volume up / corrected shape Maintain for a long time. Further, the manufacturing process can be shortened by eliminating the process of arranging the wires. Furthermore, since the lower part of the breast is pushed up over the entire surface of the layer thickness part 23, a bust-up effect with a good wearing feeling can be achieved.
Furthermore, since the inner cloth 11 is bonded to the urethane molded body 2, the portion that comes into contact with the skin cannot be bumped, the comfort is good, and the inner cloth does not move away from the urethane molded body. No damage caused by washing.

  In this embodiment, a front-fastening type brassiere is shown, but a back-fastening type brassiere in which a connector is provided on the back side has the same function and effect.
