Description

[Technical field]

[0001] The present invention relates to women's underwear having a cup portion, such as a brassiere or camisole. [Background technology]

[0002] There are two types of women's underwear with cups, such as brassieres: those with arc-shaped wires at the bottom of the cups, and those without wires. Women's underwear with cups that do not use wires is called wireless women's underwear (or wireless bras). Wireless women's underwear (wireless brassiere) comprises, for example, left and right cups for covering the bust, a base part that is sewn to the bottom edge of the cups as necessary to support them, a back part that extends from the base part to the rear side, and straps that are provided to span from the cups to the back part. Women's underwear (brassiere) that uses wires has an arc-shaped wire inserted into the bottom edge of the cups. The wire serves to maintain the shape of the cups in the shape of the wire.

[0003] Women's underwear wearers include those with full busts and those without, those with broad chests and those with thin chests, those with broad shoulders and those with narrow shoulders, those with hunched shoulders and those with sloping shoulders, and so on, and there are a wide variety of body shapes regarding the bust area. One of the main functions commonly required for the cups of women's underwear is to lift and gather the breasts together to create a beautiful décolleté and to improve the shape of the breasts. In addition, other important factors include a good fit, in which the cups fit snugly and hold the breasts firmly, regardless of the body shape of the person wearing them, and comfort when wearing them (for example, the bra cups do not float off the chest even when twisting the body from side to side, the breasts do not protrude from the sides of the bra cups even when swinging both arms, the bra does not slip up even when raising both hands, the straps do not fall off the shoulders even when rolling both shoulders, the breasts do not swing too much when jumping, and the back strap of the bra does not rise up even when bending forward).

[0004] Patent Document 1 is an invention for improving the shape of the bust in women's underwear, which uses a lift-up fabric to make the bust fuller. The upper end of this lift-up fabric is sewn to the upper outer corner of the brassiere cup and the end of the strap on the chest side, and the lower edge of the lift-up fabric is sewn to the cup cutout edge of the base fabric and the lower edge of the brassiere cup, respectively, and is hung diagonally between the end of the strap on the chest side and the cup cutout edge of the base fabric.

[0005] The covering area of ​​the brassiere cup with this lift-up fabric is the area from the lower part to the outer side part of the brassiere cup, and covers this area all over. As a result, when worn, by pulling the straps, the lift-up fabric can pull the bust from the sides to the lower part housed in the brassiere cup inward and upward in accordance with the fullness of the bust, which is said to have the effect of drawing the bust toward the center front and creating a beautiful décolleté at the chest.

[0006] The conventional women's underwear Z of Patent Document 2 (Figure 7) is composed of a pair of brassiere cups 100, a cup covering cloth 120, straps 170, a back portion 107, a base cloth 110, and a lift-up cloth 140, and like Patent Document 1, the lift-up cloth 140 is effective in creating a beautiful décolleté. In addition, the bottom side 102 of the brassiere cup 100 is sewn to the bottom edge 122 of the lift-up cloth 140. The side side 104 and top side 103 of the brassiere cup 100 are not sewn to the cup covering cloth 120. The lift-up cloth 140 is sandwiched between the brassiere cup 100 and the cup covering cloth 120. A hole 106 is provided in the corner portion 109 where the upper end P103 of the brassiere cup 100 is located, and an insertion portion 146 of the lift-up cloth 140 is arranged to pass through the hole 106 from the front surface 100s side to the back side of the brassiere cup 100 (FIG. 7(c)).

[0007] In Patent Document 1, the upper end of the lift-up fabric is sewn to the upper outer corner of the brassiere cup and to the end of the strap facing the chest, and the lower edge of the brassiere cup is sewn to the cup cut-out edge of the base fabric together with the lower edge of the brassiere cup. Therefore, when the body is twisted from side to side, or when the arms are swung or raised up, the brassiere cup is pulled by the strap and moves and comes off the bust, or conversely, the straps may fall off the shoulders, causing problems in terms of comfort.

[0008] Therefore, in Patent Document 2, a hole 106 is provided in the corner portion 109 of the upper end P103 of the brassiere cup 100, and the insertion portion 146 of the lift-up cloth 140 is arranged to pass through the hole 106 from the front surface 100s side to the back side, so that the brassiere cup 100 is not restricted by the movement of the lift-up cloth 140. As a result, the problem of comfort, which was a problem in Patent Document 1, is solved. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP2015-212437A [Patent Document 2] Patent No. 6446605 Summary of the Invention [Problem to be solved by the invention]

[0010] However, in Patent Documents 1 and 2, the lift-up cloth 140 is also arranged on the surface 100s side of the brassiere cup 100. The lift-up cloth 140 needs a certain degree of tensile strength and elasticity to lift up the bust B, so it is thick, for example, by using a double layer of power net. As a result, even if a cup covering cloth 120 is used to cover the lift-up cloth 140, when an outerwear 100T is worn over it, the upper side 143 of the lift-up cloth 140 appears on the outerwear 100T as a streaky step 100D, which causes a problem of impairing the appearance. This is particularly noticeable in outerwear 100T such as summer wear (FIG. 7(b)).

[0011] As described above, in Patent Document 2, the insertion portion 146 of the lift-up cloth 140 is passed through the hole 106 of the corner portion 109 of the brassiere cup 100 so as to pass from the front surface 100s side to the back surface side, so that in the corner portion 109, the insertion portion 146 enters the back surface side of the corner portion 109 and pushes the corner portion 109 to the front surface side. As a result, as in the above, the pushed-out portion becomes a step 100D and is conspicuously visible in the outerwear 100T (FIG. 7(c)).

[0012] The present invention has been made in consideration of the problems of the conventional examples as described above, and has as its object to provide women's undergarments which not only have improved shapeability and fit, but also have a cup portion which has an excellent appearance as the lift-up fabric does not show through outerwear. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The ladies' underwear A of the present invention will be described below. The ladies' underwear A of the present invention includes, for example, a brassiere type, a camisole type (not shown), and any other underwear having a brassiere cup 1. In this specification, a brassiere is taken as a representative example, and will be denoted by the same reference symbol A below.

[0021] An embodiment of a brassiere A of the present invention is shown in Fig. 1(a) to Fig. 4. The brassiere A is composed of symmetrical brassiere cups 1, a cup covering cloth 20, a lift-up cloth 40, a base cloth 10 that is used as needed, a back portion 7 (side belts 11 and 12 in the illustrated embodiment), and straps 70. In this embodiment, the brassiere A using the base cloth 10 will be mainly described. 1(b) shows a brassiere A that does not use a base cloth 10. In this case, a back portion 7 is provided on both the left and right sides of the cup covering cloth 20. Other than that, it is the same as the brassiere A that uses the base cloth 10.

[0022] The brassiere cup 1 has a double structure of an inner cup 1i and an outer cup 1o, and the periphery of the inner cup 1i and the outer cup 1o, which have the same outer shape, are sewn together. As described later, a lift-up cloth 40 is sandwiched between the two, and its bottom edge 42 is sewn to the bottom edge 2 of the brassiere cup 1. The shape of the brassiere cup 1 varies depending on the bust B and the design, for example, a shell shape (not shown) or a heart shape as shown in Fig. 1. Here, the heart shape is taken as a representative example.

[0023] The brassiere cup 1 of the present invention has a double structure as described above, and the reason for this is to provide different functions to the inner cup 1i and the outer cup 1o, respectively, to improve the bust shape and fit, and to provide a cup part with excellent appearance in which the lift-up cloth 40 does not affect the outerwear T, as described later. Therefore, the thickness of the brassiere cup 1 of the present invention when the inner cup 1i and the outer cup 1o are combined is formed to be the same as that of a normal brassiere cup. However, the thickness of the inner cup 1i and the outer cup 1o are appropriately selected depending on their functions.

[0024] The brassiere cup 1 is available in various thicknesses to suit the needs of the wearer. Pads (not shown) are also used. When pads are used, a pocket (not shown) for storing the pads is provided on the inner surface (the surface facing the wearer) of the inner cup 1i. Figures 5 and 6 show the case where no pads are used. When the wearer desires to add volume to the bust, a thicker inner cup 1i is used (Fig. 6). The brassiere cup 1 of the present invention has a double structure of an inner cup 1i and an outer cup 1o, so the inner cup 1i is used to change its thickness to suit the wearer's needs. As will be described later, the outer cup 1o is used to cover the step D that occurs between the inner cup 1i and the upper side 43 of the lift-up cloth 40 so that this step D does not appear as a line on the outerwear T (Fig. 2).

[0025] Various materials are used for the outer cup 1o and the inner cup 1i. For example, a three-layered sheet-like foam laminated fabric (foam laminated fabric) with a foamed middle layer and thin woven fabric attached to the front and back, or a two-layered sheet-like foam laminated fabric (foam backed fabric) with a thin woven fabric on the front. In this embodiment, urethane resin is used as the foam material. When molding the outer cup 1o and the inner cup 1i using these foam laminated fabrics, the original foam laminated fabric is cut to an appropriate size, pressurized and heated in a mold, and unnecessary parts are cut off to mold it into the planned shape described above.

[0026] When the outer cup 1o and the inner cup 1i are made of a sheet-like foam laminate fabric having a three-layer structure, a thin woven fabric is attached as the front and back layers 1a and 1c. When the sheet-like foam laminate fabric has a two-layer structure, a thin woven fabric is provided as the front layer 1a of the outer cup 1o, and a thin woven fabric is provided as the back layer 1c of the inner cup 1i. The outer cup 1o and the inner cup 1i made of such a foam laminated fabric have flexibility and elasticity. However, their stretchability is less than that of the lift-up cloth 40. Of course, the material of the outer cup 1o and the inner cup 1i is not limited to this, and nonwoven fabric, woven fabric such as double raschel, and other known materials can be used. In this embodiment, the case where a foam laminated fabric is used will be mainly described.

[0027] An example of an inner cup 1i using a foam laminated fabric is one that is thickest in the center and gradually decreases in thickness toward the periphery (FIG. 5). As another example of an inner cup 1i made of foam laminated fabric, the lower half 1d of the inner cup 1i that is attached to the bottom edge 2 of the brassiere cup 1 is thicker than the upper half 1e and bulges out toward the inner surface (bust side), and the thickness of the upper half 1e is gradually reduced from the lower half 1d toward the top edge 3 (Figure 6). The outer cup 1o using the foam laminated fabric is configured so that the center part is the thickest and the thickness gradually decreases toward the periphery as a whole, whether in the case of Fig. 5 or Fig. 6. As described above, the outer cup 1o only needs to be thick enough so that the step D does not affect the outerwear T, and therefore it is sufficient if the thickness does not create the step D when worn. This is also true when other known materials such as nonwoven fabric and double raschel are used.

[0028] The inner cup 1i and the outer cup 1o are sewn or glued all around to form a single brassiere cup 1, and when the two are placed together front to back, the top position K (the highest point on the surface of the brassiere cup 1) is the thickest, and the thickness gradually decreases towards the periphery as a whole.

[0029] In either case, the surface side of the outer cup 1o of the brassiere cup 1 is generally gentle and bulges forward in a bowl shape. In the brassiere cup 1 of Fig. 5, the thickness corresponding to the lower half 1d of the inner cup 1i is not shown, but it may be supplemented with a pad, or conversely, the thick part of the lower half 1d of the inner cup 1i of Fig. 6 may be composed of a pad.

[0030] The brassiere cup 1 is for directly containing the bust B, and bulges outward in a bowl shape. The bottom edge 2 of the brassiere cup 1 curves downward and is provided to follow the wearer's verge line V. The lowest point of the bottom edge 2 is indicated by P, and its ends are the armpit end P1 and the chest end P2. The side edges 4 of the brassiere cup 1 are formed in an arc shape curved outward with a large radius, and rise from the armpit end P1 of the bottom edge 2 toward the top edge 3. The top edge 3 is the edge between the top end P3 of the side edge 4 and the chest end P2 of the bottom edge 2, and in this embodiment, it draws an S-shaped snake line.

[0031] When the top side 3 is divided into 3 or 4 equal parts, it bends and changes direction at point P4, 1 / 3 to 1 / 4 away from the top end P3 (2 / 3 to 3 / 4 away from the chest end P2), and at this point where the direction of bending changes (inflection point), the short side from the top end P3 to point P4 draws a gentle upward curve, while the long side from the chest end P2 to point P4 draws a large upward curve. Both upward curves are smoothly connected to a downward curve at point P4. The bottom side 2, top side 3, and side side 4 are smoothly connected by a circular arc (see Figure 1). For ease of understanding, the brassiere cup 1 has been described as being divided into the bottom edge 2, top edge 3, and side edge 4, but the top edge 3 and side edge 4 may be connected to form a single top edge.

[0032] The portion near the intersection of the top edge 3 and the side edge 4 of the brassiere cup 1 is a corner portion, and this point is designated as an upper end P3. A hole 6 is provided in a corner portion 1o9 of the outer cup 1o that constitutes the brassiere cup 1. This hole 6 is formed in a slit shape, and the direction in which the hole 6 is formed is approximately parallel to and close to the side edge 4 of the brassiere cup 1 (i.e., the outer cup 1o), and is formed in a direction that intersects (perpendicular or at an angle close to perpendicular) with the longitudinal direction of the insertion portion 46 that is inserted into this slit-shaped hole 6, as described below. The width (slit width) 6w of the slit-like hole 6 in the longitudinal direction is equal to or larger than the width 46w of the insertion portion 46 that passes through the slit-like hole 6.

[0033] The cup covering cloth 20 is a thin cloth arranged to cover the entire brassiere cup 1, and the upper edge 3 and the side edge 4 of the brassiere cup 1 are not sewn to the cup covering cloth 20, and only the lower edge 2 of the brassiere cup 1 is sewn to the lower edge 22 of the cup covering cloth 20, and is separated from the surface of the brassiere cup 1. The sewn range of the lower edge 2 of the brassiere cup 1 is the entire area from the armpit end P1 to the chest end P2. The armpit end P1 is provided between the lowest point P of the lower edge 2 and the armhole side end 22a that leads to the armhole 25. The side edge 24 of the cup covering cloth 20 is the edge that extends from the armhole side end 22a to the strap connection part 23a and forms part of the armhole 25.

[0034] The cup covering cloth 20 may be made of one part as shown in Figure 4, or may be made of two parts (not shown). When made of two parts, sewing the joints will result in the same shape as when made of one part.

[0035] The cup covering fabric 20, which is made up of one part, is pressurized and heated in a mold so as to draw a gentle sphere that conforms to the outer shape of the brassiere cup 1. The material used is one that can be pressurized and heated in a mold, such as a power net made of polyurethane fiber or other highly elastic material, or knitted lace. Furthermore, a thin lace fabric made of a material with high elasticity (particularly, in FIG. 1, it is more elastic in the horizontal direction "direction perpendicular to the upper side 23" than in the vertical direction "direction parallel to the upper side 23") is used. When it is made up of two parts, it is made up of an upper part and a lower part, and the material is a fabric that is less stretchy and cannot be molded by heat and pressure using a mold. The joints between the upper part and the lower part are sewn together, and the surface is bulged out to fit the outer shape of the brassiere cup 1.

[0036] As shown in Fig. 4, the lower edge 22 of the cup covering cloth 20 is a downward U-shape along the burgess line V, with its ends defined as the armhole side end 22a and the connecting end 22b. The side edge 24 constituting a part of the armhole 25 rises upward from the armhole side end 22a and reaches the strap connecting part 23a. The edge between the strap connecting part 23a and the connecting end 22b is the upper edge 23.

[0037] The lower edge 22 of the cup covering cloth 20 is longer than the lower side 2 of the brassiere cup 1, and the lower side 2 of the brassiere cup 1 is sewn between the armhole side end 22a and the connecting end 22b of the lower edge 22 of the cup covering cloth 20. The sewing range of the bottom side 2 of the brassiere cup 1 to the bottom edge 22 of the cup covering cloth 20 is from the side edge P1 to the bust edge P2. As described above, the side edge P1 is provided between the lowest point P of the bottom side 2 and the sleeve opening edge 22a that leads to the sleeve opening 25.

[0038] As shown by the arrow in FIG. 4, cup covering cloth 20 tends to stretch diagonally upward (toward the shoulders) from lower edge 22 toward strap connection portion 23a, but stretches less in the perpendicular direction than in the diagonally upward direction. However, the longitudinal and lateral stretch of the cup covering cloth 20 is smaller than that of the lift-up cloth 40 described below.

[0039] The lift-up cloth 40 is provided so as to be sandwiched between the inner cup 1i and the outer cup 1o of the brassiere cup 1. The lower side 42 of the lift-up cloth 40 is formed to match the lower side 2 of the brassiere cup 1, and is sewn or bonded integrally to the lower side 2. The straight side extending from the chest side end Q2 of the lower side 42 of the lift-up cloth 40 toward the strap 70 is defined as the upper side 43, and the side extending from the armpit side end Q1 of the lower side 42 toward the strap 70 is defined as the side 44. The thin, string-like portion between the upper side 43 and the side 44 is defined as the insertion part 46, and the upper end of the insertion part 46 is defined as the upper end side 45 connected to the strap 70. The insertion part 46 is inserted into the hole 6 of the outer cup 1o of the brassiere cup 1 as described later.

[0040] The material of the lift-up cloth 40 is a spandex fabric or a power net fabric, and here, the lift-up cloth 40 is folded and double-layered, with its top edge 43 extending linearly at the folded edge (FIG. 4). The side edge 44 is formed into a large concave arc shape. The insertion portion 46 sandwiched between the upper portion of the upper edge 43 and the upper portion of the side edge 44 extends in a thin band shape as described above, and its upper end edge 45 is connected to the end of the strap 70 on the chest side. The cut side edge 44 of the folded lift-up cloth 40 is sewn together on both sides in a manner that does not impair its elasticity.

[0041] 4, the stretch direction of the lift-up cloth 40 is greater in the direction parallel to the top side 43 than in the direction perpendicular to this direction. Therefore, when tension is applied to the lift-up cloth 40 while it is being worn, a large tension is generated between the bottom side 42 and the top end side 45, and the cloth stretches significantly from the bottom side 42 toward the shoulders, but the stretch in the direction perpendicular to this stretch direction is small, and the bust B in this portion is effectively pulled toward the chest side (inside).

[0042] If the bottom side 42 of the lift-up cloth 40 is enlarged as in FIG. 3(a), the bust lifting range of the bottom side 42 becomes wider, and the entire bust B is lifted via the inner cup 1i. When the lower edge 42 is small as shown in FIG. 3(b) and the lower edge 42 of the lift-up cloth 40 is sewn beyond the lowest point P of the brassiere cup 1 toward the side end P1, the bust-pushing effect from the side end P1 via the inner cup 1i is enhanced. The lift-up cloth 40 in the brassiere cup 1 is covered by the outer cup 1o, so that the linear step D occurring along the upper side 43 of the lift-up cloth 40 does not appear on the surface of the outer cup 1o.

[0043] A base cloth 10 which forms the front part 5 of the women's undergarment A is provided as necessary. Here, the case where the base cloth 10 is used is taken as a representative example. The base cloth 10 has a cup hollowing edge 13 which is arc-shaped and carved into a W shape on the left and right, as shown in FIG. 4, for example. Side belts 11 and 12 which form the back part 7 of the women's undergarment A extend left and right from the base cloth 10 (FIG. 1(a)). (Alternatively, when the base cloth 10 is not used, the side belts 11 and 12 extend left and right from the cup covering cloth 20 (FIG. 1(b)).)

[0044] The lower edges 22 of the left and right cup covering fabrics 20, the lower edge 42 of the lift-up fabric 40, the lower edge 2 of the brassiere cup 1, and the non-elastic tape 28 are further overlapped and sewn together at the cup hollowing edge 13 to form a thin, linear W-shaped cup support portion 14 that fits into the verge line V.

[0045] In this embodiment, no wire is used in this portion (cup support portion 14). Therefore, unlike when a wire is used, the shape of cup support portion 14, which is the bottom edge of the cup portion, is not uniquely determined, and it is more flexible than when a wire is used. However, although cup support portion 14 is thick and bends flexibly, it has no stretchability in the longitudinal direction. When worn, it comes into soft contact with the verge line V of the bust B. The tension of lift-up cloth 40 in cup support portion 14 is generated in the bottom edge 42 of lift-up cloth 40 as described above.

[0046] In the embodiment shown in the figures, the base cloth 10 and the side belts 11 and 12 are made of cloth or lace. One side belt 11 has a male fastening member 11a at its end, and the other side belt 12 has a female fastened member 12a at its end. The base cloth 10 and the side belts 11 and 12 are more elastic and stretchable in the longitudinal direction than in the lateral direction, as shown by the cross arrows in Fig. 4.

[0047] When the base cloth 10 is not provided, the connecting end 22b of the brassiere cup 1 is connected via the cup connecting cloth 50, and a non-elastic tape 28 is overlapped and sewn to the bottom side 2 of the brassiere cup 1 to provide strength. The side belts 11 and 12 which form the back part 7 of the women's undergarment A extend from the lower edge 22 of the cup covering cloth 20 (particularly, the position on the lower edge 22 which corresponds to the lowest point P of the brassiere cup 1) to the armhole side end 22a or the side end P1 to the left and right (FIG. 1(b)).

[0048] The cup connecting cloth 50 connects the portions (facing portions) 8 of the upper sides 3 of the left and right brassiere cups 1 near the chest side ends P2. The cup connecting cloth 50 is made of a double-folded highly elastic cloth such as power net. The cup connecting cloth 50 stretches more in the connecting direction of the left and right brassiere cups 1 than in the direction perpendicular thereto, and is elastic and stretches well. Both sides of the cup connecting cloth 50 are sewn to the portions 8 near the chest side ends P2 as described above, and the bottom side of the cup connecting cloth 50 is sewn to the W-shaped thin linear cup support portions 14 on both sides including the mountain-shaped portions 52 between the left and right cup hollowing edges 13 of the base cloth 10.

[0049] The cup connecting cloth 50 connects the left and right brassiere cups 1 together, and is therefore exposed to the outside between the brassiere cups 1. Therefore, in this embodiment, the cup connecting cloth 50 is hidden in consideration of the shape, structure, and attachment position of the cup covering cloth 20. That is, the connecting ends 22b of the left and right cup covering cloths 20 extend to the lower side 2 of the brassiere cup 1 on the opposite side, and are overlapped vertically on the cup connecting cloth 50 so as to hide them.

[0050] The insertion portion 46 of the lift-up cloth 40, the lower edge 42 of which is sewn to the brassiere cup 1 and the base cloth 10, covers the lower surface of the inner cup 1i of the brassiere cup 1, is inserted through the slit-shaped hole 6 in the corner portion 1o9 of the outer cup 1o from the back side to the front side, and its upper end edge 45 is connected to one end (the end on the chest side) of the strap 70 together with the strap connection portion 23a of the cup covering cloth 20. The other end (the end on the back side) of the strap 70 is connected to the center of the upper edge of each of the side belts 11 (12).

[0051] The width 46w of the insertion part 46 of the lift-up cloth 40 is formed to be equal to or smaller than the slit opening width 6w of the slit-shaped hole 6 as described above. In the latter case, the contact resistance is smaller than when the slit width 6w is equal to the width 46w of the insertion part 46, so that the movement of the insertion part 46 in the longitudinal direction relative to the slit-shaped hole 6 is easier than when the slit width 6w is equal to the width 46w of the insertion part 46. Furthermore, since the slit opening width 6w is larger than the width 46w of the insertion part 46, the movable range of the insertion part 46 in the slit direction is increased, and even if the position of the strap 70 is shifted to match the wearer's body shape (for example, if the shoulders are wide, the distance between the left and right straps 70 will be wider, and vice versa), this amount of shift is absorbed within this margin, and the brassiere cup 1 can always be held at the bust B position. As can be seen from FIG. 1, the upper side 43 of the lift-up cloth 40 passes through a portion that coincides with the top position K of the brassiere cup 1 or passes through portions above and below the top position K and adjacent thereto.

[0052] Next, we will explain the operation of the women's undergarment A when it is worn. When this women's undergarment A is worn, the side belts 11 and 12 connected by the fastening member 11a and the fastened member 12a stretch the base cloth 10, lightly tightening it around the wearer's waist, and the straps 70 pull up the cup covering cloth 20 and the lift-up cloth 40 toward the shoulders as shown by the arrows (see FIG. 1). The cup support parts 14 fit into the verge line V of both breasts B and support the breasts B from below. The cup support parts 14 do not have wires and therefore do not stretch, but they flexibly deform to fit the size of the bust B or the shape of the verge line V, softly touching the verge line V (improving the fit).

[0053] Since the entire lower side 2 of the brassiere cup 1, the lower edge 22 of the cup covering cloth 20, and the lower side 42 of the lift-up cloth 40 are sewn together as described above, the bust B is lifted up by the lower side 42 of the lift-up cloth 40 via the inner cup 1i of the brassiere cup 1.

[0054] In addition, the outer cup 1o of the brassiere cup 1 has the insertion portion 46 of the lift-up cloth 40 inserted from the back side to the front side through the slit-shaped hole 6 provided in the corner portion 1o9 of the outer cup 1o. The slit-shaped hole 6 can easily move in the longitudinal direction to a certain extent relative to the insertion portion 46 connected to the strap 70 and hung from the shoulder. In other words, the brassiere cup 1 can move relative to the insertion portion 46 of the lift-up cloth 40. As described above, the portion of the insertion portion 46 that passes through the slit-shaped hole 6 is narrower than the slit-shaped hole 6, but as can be seen from Fig. 1, the width increases sharply at a portion slightly below the slit-shaped hole 6 (for example, at a position about 10 mm below the slit-shaped hole 6 toward the lower side 42), exceeding the slit width 6w of the slit-shaped hole 6. This prevents the insertion portion 46 of the brassiere cup 1 from moving unrestrictedly in the longitudinal direction.

[0055] In this relationship between the brassiere cup 1 and the lift-up cloth 40, when the strap 70 moves horizontally in the width direction of the insertion part 46 (the slit direction of the hole 6), the insertion part 46 gets caught on the edge of the slit-shaped hole 6, and the brassiere cup 1 also moves by the amount of movement after engagement. In other words, the top edge 3 and the side edge 4 of the brassiere cup 1 are restrained horizontally with a certain range of leeway by the insertion of the insertion part 46. In other words, the top edge 3 and the side edge 4 of the brassiere cup 1 are not completely free, but are restrained by the lift-up cloth 40 with a certain range of leeway, eliminating instability.

[0056] When this brassiere A is worn, if the bust B is large compared to the brassiere cup 1 as shown in Fig. 5, the brassiere cup 1 containing the bust B is pushed by the ample bust B and falls forward around the bottom edge 2. At this time, the insertion portion 46 of the lift-up cloth 40 moves smoothly downward through the slit-like hole 6 in the outer cup 1o of the brassiere cup 1, enveloping the bust B.

[0057] 6, when the bust B is small compared to the brassiere cup 1, the tension of the cup covering fabric 20 covering the brassiere cup 1 from above causes the brassiere cup 1 to rise around its lower edge 2. At this time, the insertion portion 46 of the lift-up fabric 40 moves smoothly upward through the slit-shaped hole 6 in the outer cup 1o of the brassiere cup 1, enveloping the bust B. The brassiere cup 1 is raised and lowered by a cup covering cloth 20 that is connected to a strap 70 and wraps the entire brassiere cup 1 from its front side. Furthermore, if the lower half 1d of the brassiere cup 1 is made thicker (or if a pad is inserted to make it thicker) as shown in FIG. 6, the bust-up effect can be enhanced. In either case, the brassiere cup 1 can accommodate the size of the bust B with a certain degree of tolerance by being raised and lowered as described above, and since it is wireless and does not have a wire inserted into the cup support part 14, a certain cup size can cover cup sizes around it, so the cup size can be reduced compared to the conventional example which used a wire.

[0058] Next, when a person wearing this ladies' undergarment A puts on outerwear T over it, the outerwear T comes into contact with the cup covering fabric 20 of the brassiere A (FIG. 2). In the conventional women's underwear Z, as shown in Fig. 7(b), the lift-up cloth 140 is provided on the front side of the brassiere cup 100, so that a step 100D corresponding to the thickness of the lift-up cloth 140 is generated between the surface 100s of the brassiere cup 100 and the upper side 143 of the lift-up cloth 140. The cup covering cloth 120 is provided on the lift-up cloth 140, and since the fabric for covering the step 100D is thin, such as lace, it bends along the step 100D and cannot eliminate the step 100D. As a result, the outer 100T in contact with the cup covering cloth 20 is also affected, and a streak along the step 100D appears on the surface of the outer 100T.

[0059] 7(c), in the conventional women's underwear Z, the insertion portion 146 of the lift-up cloth 140 is passed through the hole 106 of the corner portion 109 of the brassiere cup 100 from the front side to the back side. As a result, the insertion portion 146 that has entered the back pushes up the corner portion 109 to the front side, and a step 100D is generated in this portion. This step 100D affects the outerwear 100T in the same manner as described above.

[0060] In contrast, as already mentioned, in the present invention, the portion of the lift-up cloth 40 below the insertion portion 46 is stored inside the brassiere cup 1, and the step D of the upper side 43 of the lift-up cloth 40 is not visible on the surface of the outer cup 1o due to the cover of the outer cup 1o. As a result, it does not affect the outerwear T (Fig. 2(b)). In addition, in the brassiere cup 1, the insertion portion 46 of the lift-up cloth 40 is passed through the hole 6 in the corner portion 1o9 of the outer cup 1o from the back side to the front side. As a result, the insertion portion 46 located on the front side presses the corner portion 1o9 from above, so the corner portion 1o9 does not float to the front side, and no step D occurs in this portion. As in the above, this portion does not affect the outer T.

[0061] As a result of the above, it has become possible to provide women's underwear that not only has improved shapeability and fit, but also has a cup portion with an excellent appearance as the lift-up fabric does not show through outerwear. [Explanation of symbols]
