Garment with bra cups

Abstract

To provide a garment having bra cups capable of maintaining an ideal bust line by enhancing an appropriate bust-correcting effect produced by an inner cup provided within the bra cup.SOLUTION: A first inner cup made of an elastic material is provided within a bra cup so as to extend from a bust middle portion 16 to a bust lower portion 17 along a bust root line from a shoulder-side top to a chest-side edge. Two V-shaped grooves are formed at inner portions in the longitudinal direction of the first inner cup so as to extend in directions providing the shortest distance from the apex side of the bra cup toward the bust root line. The first inner cup is divided into three regions, namely, a side region, a lower region and a central chest region, based on the grooves as reference points, thereby wrapping and correcting the bust within the bra cup. Furthermore, grooves or elongated holes are formed from the bottoms of the V-shaped grooves toward the bust root line to enhance the stretching action of the first inner cup.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] This invention relates to women's clothing with conical bra cups that encase the left and right breasts, as typified by brassieres, and that are independent of each other. The bra cup has a first inner cup made of a stretchy material that runs from the top of the shoulder to the side and along the verge line, and grooves are made in two longitudinal positions on the inside of the first inner cup from the apex of the bra cup toward the verge line. Using these grooves as base points, the inner cup is divided into three sections: the side of the inner cup, the bottom of the inner cup, and the center of the chest side of the inner cup, which encase and correct the bust within the bra cup, and as a combined method, a wire is installed within the verge line to encase and correct the bust within the bra cup. [Background technology]

[0002] Among brassieres, which are a typical type of women's underwear with conventional bra cups, there are molded-cup brassieres in which the bra cups themselves stretch, as one way to shape the bust as intended by the wearer.Molded-cup brassieres have multiple fabrics that make up the bra cups made of stretchable material, and there are brassieres with inner cups made of polyurethane foam inside the bra cups to support the bust (breasts) within the bra cups.

[0003] However, while increasing the stretchability (elasticity) of the inner cup inside the bra cup can expand the range of bust (breast) sizes that can be accommodated, depending on the shape of the wearer's bust (breasts), the support can be weakened, and the bra cup can easily float with changes in the wearer's movements, causing the bust to move freely within the bra cup, resulting in problems with the bust not being properly adjusted and held in place. Conversely, reducing the stretchability (elasticity) of the inner cup inside the bra cup to adjust the bust and increase its firm hold can also cause problems with an oppressive feeling, particularly due to the tightness around the bust.

[0004] To address this issue, several inner cups have been devised that have improved stretchability (elasticity) and deformability for the inner cups placed inside the bra cups. For example, Patent Document 1 discloses a bra with multiple slits in the inner cup, each extending vertically. The slits open when the bra is worn, improving breathability and allowing for adjustable stretchability. Patent Document 2 discloses a garment with a stretchable inner cup inside the bra cup, with the inner cup having multiple elongated holes in the circumferential direction and a wavy upper edge. Patent Document 2 also discloses a bra with multiple slits in the inner cup, each extending vertically. The slits open when the bra is worn, improving breathability and allowing for adjustable stretchability.

[0005] However, in Patent Document 1, the inner cup has multiple slits, each extending vertically. The slits open when the bra is worn, improving breathability and allowing for adjustable stretch. However, the inner cup covers the entire bra cup, and reducing the inner cup's stretchability to improve support may result in a tighter feeling of pressure, particularly around the bust, potentially creating an oppressive feeling. Furthermore, the document makes no mention of the structure of the inner cup itself, which applies pressure to the bust via the bra cup, which varies depending on the side and underbust areas of the bra cup. Patent Document 2 features a stretchable inner cup inside the bra cup, with multiple elongated holes in the circumferential direction and a corrugated upper edge. However, the inner cup covers the entire bra cup, and reducing the inner cup's stretchability to improve support may result in a tighter feeling of pressure, particularly around the bust, potentially creating an oppressive feeling. Furthermore, there is no mention of the structure of the inner cup itself, which causes different pressures from the bust to the bra cup inside the bra cup, with the pressure being applied to the bust via the bra cup at the sides and under the bust.

[0007] [Patent Document 2] International Publication No. W02019 / 163201 Summary of the Invention [Problem to be solved by the invention]

[0008] Therefore, in clothing with bra cups, such as brassieres with inner cups inside the bra cups, increasing the extensibility (stretchability) of the inner cup inside the bra cup reduces support and prevents a firm hold, while decreasing the extensibility (stretchability) of the inner cup increases the feeling of tightness around the bust and creates an oppressive feeling.In light of this, the present invention aims to provide clothing with bra cups that can comfortably adapt to the different bust shapes of women, by using an inner cup inside the bra cup to correct the bust in the middle and lower sections of the bra cup, which are the sections that bear the most strain from the bust, thereby alleviating the feeling of pressure and intimidation when a woman wears a bra or clothing with bra cups, while improving the appropriate bust correction effect. [Means for solving the problem]

[0009] In order to solve the above problems, the present invention provides: 1. The bra cups are cone-shaped and encase the left and right busts independently, covering and correcting each bust. There A first inner cup made of a stretch material is provided inside the bra cup, and the first inner cup is provided in a section that starts from the shoulder side top of the bra cup, follows the verge line which is the base line of the bust of the bra cup, and ends at the chest side edge of the bra cup, and the width of the first inner cup is within a range of 2 / 3 of the distance from the verge line to the apex of the bra cup at its widest point, The first inner cup is sewn to the bra cup at a point where it starts from the shoulder-side top of the bra cup that contacts the outer periphery of the bra cup, and a line that contacts the verge line and ends at the point where it contacts the chest-side edge of the bra cup, and other points facing the apex of the bra cup are not sewn to the bra cup. In the first inner cup, a first groove and a second groove are provided in two longitudinally inner positions facing the apex of the bra cup in a direction that is the shortest distance toward the verge line of the bra cup, and the first inner cup is sewn from the shoulder-side top of the bra cup along the verge line.

The garment having the bra cups described in 3 above is characterized in that a wire is provided at the verge line, which is the base line of the bust of the bra cups. [Effects of the Invention]

[0010] According to the first invention, In order to accommodate the wide variety of bust (breast) sizes and shapes of an unspecified number of bra wearers, a first inner cup made of stretch material is provided inside the bra cup, and the first inner cup is installed in a section starting from the shoulder top of the bra cup, along the verge line, which is the base line of the bust of the bra cup, and ending at the chest edge of the bra cup, with the width of the first inner cup being within 2 / 3 of the distance from the verge line to the apex of the bra cup at its widest point. The first inner cup is sewn to the bra cup from the shoulder top of the bra cup on the line that meets the verge line to the end where it meets the chest edge of the bra cup, and the other parts facing the apex of the bra cup are not sewn to the bra cup. The first inner cup wraps the bust with stretch fabric from the lower to middle part of the bust, where the most stress is placed on the bra cup, and supports the sides of the bust with targeted pressure, allowing for ideal bust formation. The first inner cup is provided with a first groove and a second groove at two locations on the inside in the longitudinal direction facing the apex of the bra cup, as grooves facing the shortest distance toward the verge line of the bra cup; when the first inner cup is divided into three sections, the side section of the first inner cup, the lower section of the first inner cup, and the center section of the chest side of the first inner cup, from the top on the shoulder side along the verge line to the chest edge of the bra cup, the first groove is provided at the boundary between the side section of the first inner cup and the lower section of the first inner cup, and the second groove is provided at the boundary between the lower section of the first inner cup and the center section of the chest side of the first inner cup; by making both the first groove and the second groove V-shaped, the first inner cup is roughly divided into three sections, the side section of the inner cup, the lower section of the inner cup, and the center section of the chest of the inner cup, and excessive interference from adjacent sections due to changes in the movement of the bra wearer's body is prevented, and the respective corresponding sections are The bra can stretch to accommodate the load from the facing bust, allowing the bra cups to maintain targeted pressure on the bust.Furthermore, by providing grooves on the skin side of the first inner cup in the shortest section connecting the bottom of each of the first and second grooves of the first inner cup to the verge line, when the bra is worn, the first and second grooves of the first inner cup and the grooves provided in each groove work together to cushion the load from the bust between adjacent sections, preventing excessive interference from adjacent sections due to changes in the behavior of the bra wearer's body from the adjacent sections separated by the first and second grooves.The inner cups of each section can stretch to accommodate the load from the facing bust, allowing the bra cups to maintain targeted pressure on the bust.

[0011] In the form of the first invention, according to the second invention, the holding force is increased by the effect of the wire attached to the verge line, which has the effect of correcting the bust by "pushing" and "lifting" it, and the support force provided by the wire is increased, preventing the bra cups from slipping off the bust (breasts) as the body's movements change.

[0012] According to the third invention, in order to accommodate the wide variety of bust (breast) sizes and shapes of an unspecified number of brassiere wearers, a first inner cup made of a stretchable material is provided inside the bra cup, and the first inner cup is set in a section starting from the shoulder side top of the bra cup, along the verge line, which is the base line of the bust of the bra cup, and ending at the chest side edge of the bra cup, with the width of the first inner cup being within 2 / 3 of the distance from the verge line to the top of the bra cup at its widest point. The first inner cup is sewn to the bra cup from the line that starts at the point where it touches the verge line to the end where it touches the chest edge of the bra cup, and the other parts facing the apex of the bra cup are not sewn to the bra cup. The stretch fabric envelops the bust from the lower to middle part of the bust, where the most pressure is placed on the bra cup, and supports the sides from the bottom of the bust with targeted pressure, achieving an ideal bust shape. The first inner cup is attached to the verge line of the bra cup at two points on the inside longitudinally facing the apex of the bra cup. The first groove and the second groove are provided as grooves facing in the direction of the shortest distance toward the line, and when the first inner cup is divided into three parts, the side part of the first inner cup, the lower part of the first inner cup, and the center part of the chest side of the first inner cup, from the top of the shoulder side along the verge line to the chest side edge of the bra cup, the first groove is provided at the boundary between the side part of the first inner cup and the lower part of the first inner cup, and the second groove is provided at the boundary between the lower part of the first inner cup and the center part of the chest side of the first inner cup, and by making both the first groove and the second groove V-shaped, the first inner cup is divided into three parts, the side part of the inner cup, the lower part of the inner cup, and the center part of the chest side of the inner cup The bra is roughly divided into sections, which prevent excessive interference from adjacent sections due to changes in the wearer's body movements, and can stretch to accommodate the load from each opposing bust, maintaining appropriate pressure on the bust from the bra cups.Furthermore, by providing long holes near the middle of the shortest line connecting the bottom of each of the first and second grooves to the verge line, when the bra is worn, the first and second grooves of the first inner cup and the long holes provided in each groove work together to cushion the load from the bust between adjacent sections,The first and second grooves prevent excessive interference from the adjacent sections due to changes in the wearer's body movements, and the inner cups of each section can stretch to accommodate the load from the opposing bust, maintaining even pressure on the bust from the bra cups.

[0015] The present invention will be described below with reference to a brassiere 2, using a brassiere as a representative example of clothing with bra cups. In this invention, the breasts are referred to as the bust 1. The base line of the bust, which is said to be the line where the lower part of the bust joins the human body, is referred to as the verge line 5. (Overall structure of the bra)

[0016] In the present invention, when the distance from the bra cup apex 4 to the verge line 5 of the bra cup 3 or the bust (breasts) contained in the bra cup 3 is divided into thirds on the line connecting the bra cup apex 4 and the verge line 5 in the shortest distance, these three sections are called the upper bust section 15, the middle bust section 16, and the lower bust section 17, respectively, from the bust apex 4 side to the verge line 5 side. Furthermore, in the present invention, when the first inner cup is divided into three sections, the armpits, lower bust section, and center chest section, from the shoulder top along the verge line to the chest edge of the bra cup, these three sections are called the armpits of the first inner cup, the lower section of the first inner cup, and the center chest section of the first inner cup, or the armpits of the bra cup, the lower section of the bra cup, and the center chest section of the bra cup, respectively. Furthermore, in the present invention, the expression "high" or "low" regarding the stretchability (elasticity) of the materials used for the first inner cup and the second inner cup means that a material with high stretchability (elasticity) is a material that easily stretches when a load is applied, and conversely, a material with low stretchability (elasticity) is a material that does not easily stretch when a load is applied. In the present invention, a brassiere of the type that does not have a wire in the vestibule 5 of the brassiere 2 is described as Example 1, and a brassiere of the type that has a wire in the vestibule 5 of the brassiere 2 is described as Example 2. Therefore, the only difference between Example 1 and Example 2 is whether or not a wire is provided in the vestibule 5 of the brassiere 2.

[0017] The brassiere 2 shown in FIG. 1 of the first embodiment of the present invention is a representative example of the area around the bra cup 3 on the left side of a woman's chest. For purposes of explaining the present invention, the left breast side of the brassiere 1 is shown. FIG. 2 is an explanatory diagram of the section between A and B in FIG. 1, illustrating the direction of circumferential load from the bust 1 between the first inner cup side portion 21 and the first inner cup lower portion 22, which are separated by the first groove. FIG. 3 is an explanatory diagram of the section between C and D in FIG. 1, illustrating the direction of circumferential load from the bust 1 between the first inner cup lower portion 22 and the first inner cup chest center portion 23, which are separated by the second groove. FIG. 4 is an explanatory diagram of the section between E and H in FIG. 1 when the first inner cup 20 is installed in the bra cup of the first embodiment. In the present invention, the base line of the bust of a brassiere is called the verge line 5, and the brassiere does not have a wire at the verge line 5. The brassieres of Examples 1 and 2 have a shaping material 10 at the verge line 5. The bra-side verge line corrector 10 is referred to as a corrector. The bra-side verge line corrector 10 has a central core and is formed by folding the fabric of the bra cup 3. A detailed description of the bra-side verge line corrector 10 will be omitted. In Example 3, the bra-side verge line corrector 10 is provided with a wire 31. Figure 5 is an explanatory diagram of the positional relationship between the first groove and the linear groove according to Example 1. Figure 6 is an explanatory diagram of the operation of the first groove and the linear groove when excessive load is concentrated from the bust 1 to the lower part of the first inner cup 22 according to Example 1. Figure 7 is an explanatory diagram of the linear groove according to Example 1 or Example 2. The structure is the same for both Examples 1 and 2. Figure 8 is an explanatory diagram of the positional relationship between the first groove and the elongated hole according to Example 1. Figure 9 is an explanatory diagram of the operation of the first groove and the elongated hole when excessive load is concentrated from the bust 1 to the lower part of the first inner cup 22 according to Example 1.

[0018] The purpose of the brassiere 2 is to shape and correct the bust 1. Broadly speaking, the brassiere 2 is made up of bra cups 3 that adjust the bust 1 to the proper shape, and belts 6 and straps 7 that secure the bra cups 3 to the bust 1. The brassiere 2 is made up of two independent bra cups 3 (only one side is shown in Figures 1 and 10) that are cone-shaped with the apex 4 of the bra cup at the apex and are attached to each of the left and right busts 1 to properly shape the bust 1, a belt 6 that connects the bra cups 3 together at the center of the chest and runs around the back from the edge of the left cup to connect to the edge of the right cup, securing the bra cups 3 of the brassiere 2 to the bust 1 from the side of the chest, straps 7 that run from the top of the bra cups 3 around the shoulders and connect to the belt 6 on the back, and a male and female hook fasteners at both ends of the belt 6 that connect the belt 6, which is cut at the center of the back.

[0019] In this invention, the base fabric sewn to the vestibule line 5 of the bra cup 3, the side panel fabric sewn to the sides of the bra cup 3, and the belts extending laterally from the left and right side panel fabrics are referred to as the belt 6. Stretch tape is sewn to the side lines of the belt 6. This stretch tape also extends from the side lines of the belt 6 to the upper part of the bra cup 3 where the side lines of the belt 6 connect to the straps 8, and stretch tape 9 is sewn to the top of the bra cup 3. This stretch tape reinforces various parts of the brassiere 2 itself.

[0020] Bra cups 3 are made from multiple overlapping layers of fabric, with lace fabric sewn onto outer fabric 41 as decoration. Cotton is often used for fabric 42, the backside of bra cups 3 that comes into contact with the skin, taking into account its absorbency. Commercially available bra cups 3 are typically made from urethane, polyurethane, nylon, polyester, cotton, etc. In this invention, the material used for bra cups 3 or the number of layers of fabric that make up bra cups 3 is determined during the design and manufacturing stage based on the function and suitability of the bra. This invention also omits a description of the cup seams or tape that are typically provided on the backside of bra cups 3, the skin side, to connect and form the cups themselves. [Example]

[0021] FIG. 1 shows a view from the front of the bra cup 3 surrounding the right bust 1 of a woman's left and right breasts in Example 1. A first inner cup 20 is provided at the center of multiple sheets of fiber fabric that make up the conical bra cup 3 that encases the bust 1. The first inner cup 20 is provided within the bra cup 3 in a section that starts at the shoulder-side top 8 of the bra cup 3, follows the verge line 5, which is the base line of the bust 1 of the bra cup 3, and ends at the chest-side edge 11 of the bra cup 3, with the width of the first inner cup 20 at its widest point being within two-thirds of the distance from the verge line 5 to the apex 4 of the bra cup. As shown in FIG. 4, when viewed from the bust, the bra cup lining fabric 42 is followed by the first inner cup 20 and then the bra cup outer fabric 41.

[0022] The first inner cup 20 may be made of a soft synthetic resin foam such as polyurethane foam, latex foam, or nylon polyurethane foam. The appropriate material is determined at the time of design.

[0023] The first inner cup 20 is sewn to the bra cup 3 along a line starting from the shoulder top 8 of the bra cup 3, passing through a line tangent to the verge line 5, and ending at the chest edge 11 of the bra cup 3. By sewing the section from the shoulder top 8 to the stretch tape 9 to the bra cup 2, the first inner cup 20 itself is prevented from stretching and protruding beyond the section from the shoulder top 8 to the stretch tape 9 of the bra cup 3. By sewing the section of the first inner cup 20 that contacts the verge line 5 to the bra cup 2, the first inner cup 20 itself is prevented from stretching and protruding beyond the verge line 5. By sewing the section of the first inner cup 20 that contacts the chest edge 11 of the bra cup 3 to the bra cup 3, the first inner cup 20 itself is prevented from stretching and protruding beyond the chest edge 11 of the bra cup 3. That is, for the purpose of stretching the first inner cup 20, the section (location) facing the apex 4 of the bra cup 3 is not sewn to the bra cup 3.

[0024] V-shaped grooves are provided in two longitudinally inner positions of the first inner cup 20 facing the bra cup apex 4 that is not sewn to the bra cup 3, in the direction that is the shortest distance toward the verge line 5 of the bra cup 3. A first groove 24 and a second groove 25 are provided in this order from the side of the bra cup 3. When the first inner cup 20 is divided into three parts, a first inner cup side portion 21, a first inner cup lower portion 22, and a first inner cup chest side center portion 23, from the shoulder side top along the verge line 5 to the bra cup chest side edge 11, the first groove 24 is provided at the boundary between the first inner cup side portion 21 and the first inner cup lower portion 22, and the second groove 25 is provided at the boundary between the first inner cup lower portion 22 and the first inner cup chest side center portion 23.

[0025] The first groove 24 and the second groove 25, which are provided in two longitudinally inner locations of the first inner cup 20 facing the bra cup apex 4, have the same shape and depth. The first groove 24 and the second groove 25 are V-shaped. The width of the V-shape is determined during design based on the cup size and shape of the target bra 2. The depth of the V-shaped grooves of the first groove 24 and the second groove 25 is within the range of 0.5 mm to 1.5 mm. The depth of the V-shaped groove is determined based on the target bra cup size. For small bra cups 3, such as A cups, the depth is around 0.5 mm, and as the bra cup 3 increases in size from C cup to D cup, E cup, or F cup, the depth approaches a maximum value of 1.5 mm.

[0026] A groove 26 is provided on the skin side of the first inner cup 20 on the shortest line connecting the bottom of the first groove 24 to the verge line 5. Furthermore, a groove 26 is also provided on the shortest line connecting the bottom of the second groove 25 to the verge line 5. The width of the groove 26 is determined at the time of design depending on the cup size and shape of the intended brassiere 2. For a small A-cup bra cup 3, the width of the groove 26 may be narrow, but as the bra cup 3 size increases from a C-cup to a D-cup, the width of the groove 26 tends to increase. [Example]

[0027] The difference between Example 1 and Example 2 is that in Example 1, a linear groove is provided on the shortest line connecting the bottoms of the first groove 24 and the second groove 25 of the first inner cup 20 to the verge line 5, whereas in Example 2, a long hole is provided on the shortest line connecting the bottoms of the first groove 24 and the second groove 25 of the first inner cup 20 to the verge line 5. All other structures are the same as in Examples 1 and 2. Therefore, in Example 2, all reference numerals in the drawings are the same as in Example 1 except for the long hole. Furthermore, with regard to the first groove 24 and the second groove 25 of the first inner cup 20 in Example 2, the explanatory diagrams of the embodiment, its operation, and its effects are substituted for those of Example 1.

[0028] FIG. 1 shows a view from the front of the bra cup 3 surrounding the right bust 1 of a woman's left and right breasts in Example 1. A first inner cup 20 is provided at the center of multiple sheets of fiber fabric that make up the conical bra cup 3 that encases the bust 1. The first inner cup 20 is provided within the bra cup 3 in a section that starts at the shoulder-side top 8 of the bra cup 3, follows the verge line 5, which is the base line of the bust 1 of the bra cup 3, and ends at the chest-side edge 11 of the bra cup 3, with the width of the first inner cup 20 at its widest point being within two-thirds of the distance from the verge line 5 to the apex 4 of the bra cup. As shown in FIG. 4, when viewed from the bust, the bra cup lining fabric 42 is followed by the first inner cup 20 and then the bra cup outer fabric 41.

[0029] The first inner cup 20 may be made of a soft synthetic resin foam such as polyurethane foam, latex foam, or nylon polyurethane foam. The appropriate material is determined at the time of design.

[0030] The first inner cup 20 is sewn to the bra cup 3 along a line starting from the shoulder top 8 of the bra cup 3, passing through a line tangent to the verge line 5, and ending at the chest edge 11 of the bra cup 3. By sewing the section from the shoulder top 8 to the stretch tape 9 to the bra cup 2, the first inner cup 20 itself is prevented from stretching and protruding beyond the section from the shoulder top 8 to the stretch tape 9 of the bra cup 3. By sewing the section of the first inner cup 20 that contacts the verge line 5 to the bra cup 2, the first inner cup 20 itself is prevented from stretching and protruding beyond the verge line 5. By sewing the section of the first inner cup 20 that contacts the chest edge 11 of the bra cup 3 to the bra cup 3, the first inner cup 20 itself is prevented from stretching and protruding beyond the chest edge 11 of the bra cup 3. That is, for the purpose of stretching the first inner cup 20, the section (location) facing the apex 4 of the bra cup 3 is not sewn to the bra cup 3.

[0031] V-shaped grooves are provided in two longitudinally inner positions of the first inner cup 20 facing the bra cup apex 4 that is not sewn to the bra cup 3, in the direction that is the shortest distance toward the verge line 5 of the bra cup 3. A first groove 24 and a second groove 25 are provided in this order from the side of the bra cup 3. When the first inner cup 20 is divided into three parts, a first inner cup side portion 21, a first inner cup lower portion 22, and a first inner cup chest side center portion 23, from the shoulder side top along the verge line 5 to the bra cup chest side edge 11, the first groove 24 is provided at the boundary between the first inner cup side portion 21 and the first inner cup lower portion 22, and the second groove 25 is provided at the boundary between the first inner cup lower portion 22 and the first inner cup chest side center portion 23.

[0032] The first groove 24 and the second groove 25, which are provided in two longitudinally inner locations of the first inner cup 20 facing the bra cup apex 4, have the same shape and depth. The first groove 24 and the second groove 25 are V-shaped. The width of the V-shape is determined during design based on the cup size and shape of the target bra 2. The depth of the V-shaped grooves of the first groove 24 and the second groove 25 is within the range of 0.5 mm to 1.5 mm. The depth of the V-shaped groove is determined based on the target bra cup size. For small bra cups 3, such as A cups, the depth is around 0.5 mm, and as the bra cup 3 increases in size from C cup to D cup, E cup, or F cup, the depth approaches a maximum value of 1.5 mm.

[0033] An elongated hole 27 is provided near the middle of the shortest line connecting the bottom of the first groove 24 of the first inner cup 20 to the verge line 5. Furthermore, an elongated hole 27 is provided near the middle of the shortest line connecting the bottom of the second groove 25 to the verge line 5. The length and number of elongated holes 27 are determined at the time of design depending on the cup size and shape of the target brassiere 2. For a small A-cup bra cup 3, the elongated hole 27 may be short and there may be only one hole, but as the bra cup 3 size increases from a C-cup to a D-cup, the elongated holes 27 become longer and there are multiple holes.

[0034] The following describes the operation and effects of the present embodiment described in Examples 1 and 2. The main purpose of wearing a brassiere 2 is to correct the bust 1 to an appropriate shape. The shapes of women's busts 1 (breasts) are not all the same, and vary widely. Among women whose bra cup 3 size is B cup, some find a B cup appropriate, while others have a B cup closer to an A cup, and some have a B cup closer to a C cup. The challenges of a brassiere 2 are to maintain an ideal bust line as much as possible and to reduce the weight of the bust 1 (breasts) themselves and the load caused by gravity.

[0035] The forms described in Examples 1 and 2 are not limited to molded bras, which are divided into sizes S, M, L, and LL, like molded bras in which the bra 2 size and the bra cup 3 and belt 6 are made of a stretchy material, but are also intended to apply the inner cup used in molded bras to regular bras and general clothing with bra cups, in which the underbust 1 undersize is divided into 65, 70, 75, and 80 and the bra cup sizes are divided into A, B, C, D, E, and F, to improve the holding power that supports the bust 1 and to provide a feeling of being gently embraced.

[0036] When wearing the brassiere 2, the areas in the bra cup 3 that bear the greatest load from the bust 1 are the middle 16 and lower 17 of the bust 1. In this invention, attention is focused on the middle 16 and lower 17 of the bra cup 3 that bear the greatest load from the bust 1 when wearing the brassiere 2, and the first inner cup 20 is provided in a section that starts from the shoulder-side top 8 of the bra cup 3, follows the verge line 5, which is the base line of the bust 1 of the bra cup 3, and ends at the chest-side edge 11 of the bra cup 3, with the width of the first inner cup 20 at its widest point being within 2 / 3 of the distance from the verge line 5 to the apex 4 of the bra cup. The stretchable first inner cup 20 encases the bust from the shoulder side of the bra cup along the verge line 5 to the bust middle section 16 and lower section 17, and the first inner cup 20 supports the corresponding first inner cup lower section 22, first inner cup side section 23 and first inner cup chest center section 23 with targeted pressure, achieving ideal bust formation.

[0037] The side of the first inner cup 20 facing the bust apex 4 is not sewn to the bra cup 3. When load fluctuations occur on the first inner cup 20 due to changes in the bust (breast) size of the wearer of the brassiere 2 or changes in behavior such as posture while wearing the brassiere 2, the bra cup 3 will either stretch outward and bulge to accommodate the excessive load from the bust 1 to the bra cup 3, or stretch toward the bra cup apex 4 to accommodate the load fluctuation. Because the side of the first inner cup 20 facing the bra cup apex 4 is not sewn to the bra cup 3, the first inner cup 20 stretches toward the bra cup apex 4 in response to the load fluctuation and returns to its original shape when the load returns to normal. The part of the bra cup 3 that experiences the least load from the bust itself is the upper part 15 of the bust 1. If excessive pressure is applied to the bust and the pressure can be released to the upper part 15 of the bust 1 by the stretching action of the first inner cup 20, the first inner cup 20 can support the corresponding lower part 22 of the first inner cup, the side part 23 of the first inner cup and the center part 23 of the chest side of the first inner cup with targeted pressure, thereby achieving ideal bust formation.

[0038] Furthermore, the first inner cup 20 has a first groove 24 and a second groove 25, which are V-shaped and extend in the shortest direction toward the bra cup's verge line at two locations on the inside longitudinal side facing the bra cup apex 4. The first groove 24 is located at the boundary between the first inner cup side portion 21 on the inside facing the bra cup apex 4 of the first inner cup 20 and the first inner cup lower portion 22, while the second groove 25 is located at the boundary between the first inner cup lower portion 22 on the inside facing the bra cup apex 4 of the first inner cup 20 and the first inner cup's chest-side center portion 23. As shown in FIG. 6, if a load fluctuation occurs on the first inner cup 20 due to a change in the wearer's behavior, such as posture, the first inner cup 20 will respond to the excessive load from the bust 1 to the bra cup 3 by narrowing the width of the V-shaped groove in the loaded section and expanding toward the bra cup apex 4, thereby allowing the first inner cup 20 to accommodate the excessive load. Normally, the circumferential length of the bust 1 gradually decreases toward the bust apex 4. If this V-shaped groove did not exist, the loaded and unloaded surfaces would interfere with each other on the inside longitudinal side facing the bra cup apex 4, making it difficult for the first inner cup 20 to stretch toward the bra cup apex 4. This would make it impossible to properly absorb excessive load without a time lag. If the degree of stretch of the first inner cup 20 were increased to make it easier to stretch in order to find a way to release the load to the outside of the bra cup 3, the supportive power of the bra cup 3 would decrease, and the effect of firmly supporting and correcting the bust 1 even in normal conditions could be reduced.

[0039] A first groove 24 and a second groove 25 are V-shaped and formed in two locations on the inside longitudinal side of the first inner cup 20 facing the bra cup apex 4, in the direction that is the shortest distance toward the bra cup's verge line. The first groove 24 is located at the boundary between the first inner cup side portion 21 on the inside facing the bra cup apex 4 of the first inner cup 20 and the first inner cup lower portion 22, while the second groove 25 is located at the boundary between the first inner cup lower portion 22 on the inside facing the bra cup apex 4 of the first inner cup 20 and the first inner cup chest side center portion 23. The reason why there are two V-shaped grooves in these locations is that, in the first inner cup 20, considering the direction of load from the bust 1 (breast) in the circumferential direction due to the shape of the bust 1, the direction of longitudinal extension of the load from the bust 1 changes near the boundary between the first inner cup lower portion 22 and first inner cup side portion 21 and near the boundary between the first inner cup lower portion 22 and first inner cup chest side center portion 23. In the first inner cup under-bust section, longitudinal stretch G is primarily left-right stretching, while stretch F in the first inner cup side sections 22 and stretch K in the first inner cup chest-side center section 23 change to primarily longitudinal and vertical stretching in accordance with the shape of the bra cup 3. By providing a V-shaped groove at this boundary, the roles of the first inner cup 20 are divided. The side sections 21 of the first inner cup 20 are stretched primarily in response to load from the side sections of the bust. The first inner cup lower section 22 of the first inner cup 20 is stretched primarily in response to load from the under-bust (breast) section, and the chest-side center section 23 of the first inner cup 20 is stretched primarily in response to load from the bust apex (breast apex), which is the bra cup apex 4, to the bust-chest center section of the bra cup 3. These stretching actions make the sections divided into three sections by the V-shaped grooves in the first inner cup 20 less susceptible to load fluctuations from the adjacent sections, and allow stretching to be concentrated on load fluctuations from the opposing bust 1. This structure allows targeted pressure to be applied to support the under bust, sides, and center of the bust, achieving ideal bust formation.

[0040] The first inner cup 20 of the present invention is divided into three sections by V-shaped grooves: the first inner cup side section 21, the first inner cup lower section 22, and the first inner cup chest side center section 23. Each section divided into three sections by the V-shaped grooves is further provided with two structures that are as insensitive as possible to load fluctuations from adjacent sections and can stretch by concentrating the load fluctuations from the opposing bust 1, and these are described as Example 1 and Example 2. The choice of which to adopt at the time of design depends on the style of brassiere at the time.

[0041] As a first option, a groove 26 is provided on the skin side of the first inner cup 20 described in Example 1 on the shortest line connecting the groove bottom of the first groove 24 to the verge line 5, and a groove 26 is also provided on the second groove 25 on the shortest line connecting the groove bottom to the verge line 5. As a second option, a long hole 27 is provided near the middle of the shortest line connecting the bottom of the first groove 24 to the verge line 5 of the first inner cup 20 described in Example 2, and a long hole 27 is also provided near the middle of the shortest line connecting the bottom to the verge line 5 of the second groove 25.

[0042] In the first embodiment, which is the first option, a stripe groove 26 is provided on the skin side of the first inner cup 20 on the shortest line connecting the bottom of the first groove 24 to the verge line 5, and a stripe groove 26 is also provided on the shortest line connecting the bottom of the second groove 25 to the verge line 5. This will be explained with reference to Figures 5 and 6. As shown in Figure 5, the stripe groove is elongated, and as shown in the cross-sectional view of Figure 7, it is a groove with a narrow width and a shallow depth. As shown in Figure 6, assuming that only the first inner cup lower part 22 stretches due to changes in the shape of the brassiere wearer's bust 1 or bodily behavior, the first inner cup lower part 22 stretches in the direction of the arrow. The diagonal lines indicate the stretched state. At this time, the width of the first groove 24 narrows and the width of the stripe groove 26 widens, opening diagonally upward and becoming slightly twisted, which acts to prevent the adjacent first inner cup side portion 21 from stretching as much as possible, minimizing the amount of stretch in the first inner cup side portion 21. Another advantage of providing the stripe groove 26 is that by providing the stripe groove 26, the first inner cup 20 itself becomes a base point and easily creates a rounded shape circumferentially inward to fit the bust 1, so that the first inner cup 20 itself conforms to the shape of the bust 1, improving the wearing comfort of the brassiere 2.

[0043] In the second option, Example 2, a slot 27 is provided in the first groove 24 of the first inner cup 20 near the middle of the shortest line connecting the bottom to the verge line 5. The second groove 25 also has a slot 27 near the middle of the shortest line connecting the bottom to the verge line 5. This will be explained with reference to Figures 8 and 9. As shown in Figure 8, the slot 27 is an elongated, oval-shaped hole. As shown in Figure 9, assuming that only the first inner cup lower portion 22 stretches due to changes in the shape of the brassiere wearer's bust 1 or bodily behavior, the first inner cup lower portion 22 stretches in the direction of the arrow. The diagonal lines indicate the stretched state. At this time, the width of the first groove 24 narrows. The slot 27 widens, opening diagonally upward, minimizing stretch of the adjacent first inner cup side portion 21. This minimizes stretch of the first inner cup side portion 21. [Example]

[0044] The only difference between Example 1 and Example 2 and Example 3 is whether or not a wire 43 is provided at the verge line 5 located on the periphery of the brassiere cup 3 of the brassiere 2. Other configurations and structures of Example 3 other than the wire 43 provided at the verge line 5 are all the same as those of Example 1 and Example 2. Therefore, the reference numerals on the drawings of Example 3 are all the same as those of Example 1 and Example 2 except for the wire 43.

[0045] FIG. 10 shows a view from the front of the bra cup 3 surrounding the right bust 1 of a woman's left and right breasts in Example 3. The first inner cup 20 is located at the center of multiple layers of fiber fabric that make up the conical bra cup 3 that encases the bust 1. The first inner cup 20 is located within the bra cup 3 in a section that starts at the shoulder-side top 8 of the bra cup 3, runs along the verge line 5, which is the base line of the bust 1 of the bra cup 3, and ends at the chest-side edge 11 of the bra cup 3, with the width of the first inner cup 20 at its widest point being within two-thirds of the distance from the verge line 5 to the apex 4 of the bra cup. As shown in FIG. 4, when viewed from the bust, the bra cup lining fabric 42 is followed by the first inner cup 20 and then the bra cup outer fabric 41.

[0046] As in the first embodiment, the first inner cup 20 may be made of a soft synthetic resin foam such as polyurethane foam, latex foam, or nylon polyurethane foam. The appropriate material is determined at the time of design.

[0047] As in the first embodiment, the first inner cup 20 is sewn to the bra cup 3 along a line starting from the shoulder top 8 of the bra cup 3, passing through a line tangent to the verge line 5, and ending at the chest edge 11 of the bra cup 3. By sewing the section from the shoulder top 8 to the stretch tape 9 to the bra cup 2, the first inner cup 20 itself is prevented from stretching and protruding beyond the section from the shoulder top 8 to the stretch tape 9 of the bra cup 3. By sewing the section of the first inner cup 20 that contacts the verge line 5 to the bra cup 2, the first inner cup 20 itself is prevented from stretching and protruding beyond the verge line 5. By sewing the section of the first inner cup 20 that contacts the chest edge 11 of the bra cup 3 to the bra cup 3, the first inner cup 20 itself is prevented from stretching and protruding beyond the chest edge 11 of the bra cup 3. That is, for the purpose of stretching the first inner cup 20, the section (location) facing the apex 4 of the bra cup 3 is not sewn to the bra cup 3.

[0048] V-shaped grooves are provided in two longitudinally inner positions of the first inner cup 20 facing the bra cup apex 4 that is not sewn to the bra cup 3, in the direction that is the shortest distance toward the verge line 5 of the bra cup 3. A first groove 24 and a second groove 25 are provided in this order from the side of the bra cup 3. When the first inner cup 20 is divided into three parts, a first inner cup side portion 21, a first inner cup lower portion 22, and a first inner cup chest side center portion 23, from the shoulder side top along the verge line 5 to the bra cup chest side edge 11, the first groove 24 is provided at the boundary between the first inner cup side portion 21 and the first inner cup lower portion 22, and the second groove 25 is provided at the boundary between the first inner cup lower portion 22 and the first inner cup chest side center portion 23.

[0049] The first groove 24 and the second groove 25, which are provided in two longitudinally inner locations of the first inner cup 20 facing the bra cup apex 4, have the same shape and depth. The first groove 24 and the second groove 25 are V-shaped. The width of the V-shape is determined during design based on the cup size and shape of the target bra 2. The depth of the V-shaped grooves of the first groove 24 and the second groove 25 is within the range of 0.5 mm to 1.5 mm. The depth of the V-shaped groove is determined based on the target bra cup size. For small bra cups 3, such as A cups, the depth is around 0.5 mm, and as the bra cup 3 increases in size from C cup to D cup, E cup, or F cup, the depth approaches a maximum value of 1.5 mm.

[0050] A groove 26 is provided on the skin side of the first inner cup 20 on the shortest line connecting the bottom of the first groove 24 to the verge line 5. Furthermore, a groove 26 is also provided on the shortest line connecting the bottom of the second groove 25 to the verge line 5. The width of the groove 26 is determined at the time of design depending on the cup size and shape of the intended brassiere 2. For a small A-cup bra cup 3, the width of the groove 26 may be narrow, but as the bra cup 3 size increases from a C-cup to a D-cup, the width of the groove 26 tends to increase.

[0051] The bra cups 3 are fitted with wires 43 at the verge line 5, the base line of the bust 1, for the purpose of supporting and holding the bust (breasts) 1. The wires 43 can be either circular or oval in shape to achieve a holding effect. Considering the pressure exerted by the wires 43 on the bust 1, the load exerted by the bust 1 on the wires 43, and the comfort of wearing the bra 2, an oval shape is the most appropriate. The wires 43 are determined based on the shape and size of the bra cups 3, the price of the bra 2 itself, and the design at hand. The material of the wires 43 is selected from metal wires commonly used in bras 2, such as stainless steel, amorphous alloys, and shape-memory alloys, or flexible materials such as flexible plastics, fiber-reinforced plastics, and resins. The wires 43 are determined based on the shape and size of the bra cups 3, the price of the bra 2 itself, and the design at hand. The wire 43 is stored in a belt-shaped storage bag (wire tube) made of bias tape or the like, and is attached to the verge line 5, which is the base line of the bust 1 located on the outer periphery of the bra cups 3 of the brassiere body 2.

[0052] The following describes the operation and effect of this embodiment described in Example 3. The only difference between Example 1 and Example 2 and Example 3 is whether or not a wire 43 is provided at the vestibule 5 of the brassiere 2. The advantages of providing the wire 43 at the vestibule 5 of the brassiere 2 include the effect of the wire 43 increasing the holding power, thereby correcting the bust 1 by "pushing" and "lifting" it, and the increased support power provided by the wire 43, which can prevent the bra cups 3 from slipping off the bust (breasts) 1 due to changes in body movement.

[0053] When wearing a brassiere 2, the areas in the bra cup 3 that bear the greatest load from the bust 1 themselves are the middle 16 and lower 17 of the bust 1. In this invention, focusing on the middle 16 and lower 17 of the bra cup 3 that bear the greatest load from the bust 1 when wearing a brassiere 2, the first inner cup 20 is provided in a section that starts from the shoulder-side top 8 of the bra cup 3, follows the verge line 5, which is the base line of the bust 1 of the bra cup 3, and ends at the chest-side edge 11 of the bra cup 3, with the width of the first inner cup 20 at its widest point being within 2 / 3 of the distance from the verge line 5 to the apex 4 of the bra cup. Furthermore, in Example 3, a wire 43 is provided at the verge line 5 of the brassiere 2. The parts of the bra cup 3 that contact the verge line 5 and the parts of the first inner cup 20 that contact the verge line 5 are held in close contact with the bust 1 by the wire 43 attached to the verge line, and the stretchable first inner cup 20 encases the bust from the shoulder side of the bra cup along the verge line 5 to the middle and lower parts 16 and 17 of the bust, respectively, and supports the corresponding lower part 22 of the first inner cup, the side part 23 of the first inner cup, and the center part 23 of the chest of the first inner cup with targeted pressure, and by using the wire 43 attached to the verge line 5 in combination, the bust is "pushed together" and "lifted" to achieve the ideal bust shape.

[0054] The side of the first inner cup 20 facing the bust apex 4 is not sewn to the bra cup 3. When load fluctuations occur on the first inner cup 20 due to changes in the bust (breast) size of the wearer of the brassiere 2 or changes in behavior such as posture while wearing the bra, the bra cup 3 will either stretch outward and bulge to accommodate the excessive load from the bust 1 to the bra cup 3, or stretch toward the bra cup apex 4 to accommodate the load fluctuation. Because the side of the first inner cup 20 facing the bra cup apex 4 is not sewn to the bra cup 3, the first inner cup 20 stretches toward the bra cup apex 4 in response to the load fluctuation and returns to its original state when the load returns to normal. The part of the bra cup 3 that experiences the least load from the bust itself is the upper part 15 of the bust 1. If excessive pressure is applied to the bust due to changes in bodily movement, and the wire 43 attached to the verge line 5 shown in Example 3 keeps the bra cups 3 in close contact with the bust 1 without slipping, and the stretching action of the first inner cup 20 allows the pressure to be released to the upper part 15 of the bust 1, the first inner cup 20 will support the corresponding lower part 22 of the first inner cup, the side parts 23 of the first inner cup, and the center part 23 of the chest side of the first inner cup, achieving ideal bust formation. The holding and support power of the wire 43 attached to the verge line 5 allows the bra cups 3 to adapt to changes in bodily movement, preventing them from slipping off the bust 1 and improving the stability and comfort of the bra cups 3.

[0055] Furthermore, the first inner cup 20 has a first groove 24 and a second groove 25, which are V-shaped and extend in the shortest direction toward the verge line 5 of the bra cup 3 at two locations on the inside longitudinal side facing the bra cup apex 4. The first groove 24 is located at the boundary between the first inner cup side portion 21 on the inside facing the bra cup apex 4 of the first inner cup 20 and the first inner cup lower portion 22, while the second groove 25 is located at the boundary between the first inner cup lower portion 22 on the inside facing the bra cup apex 4 of the first inner cup 20 and the first inner cup chest-side center portion 23. As shown in FIG. 6, if a load fluctuation occurs on the first inner cup 20 due to a change in the wearer's behavior, such as posture, the first inner cup 20 will respond to the excessive load from the bust 1 to the bra cup 3 by narrowing the width of the V-shaped groove in the loaded section and expanding toward the bra cup apex 4, thereby allowing the first inner cup 20 to accommodate the excessive load. Normally, the circumferential length of the bust 1 gradually decreases toward the bust apex 4. If this V-shaped groove did not exist, the loaded and unloaded surfaces would interfere with each other on the inside longitudinal side facing the bra cup apex 4, making it difficult for the first inner cup 20 to stretch toward the bra cup apex 4. This would make it impossible to properly absorb excessive load without a time lag. If the degree of stretch of the first inner cup 20 were increased to make it easier to stretch in order to find a way to release the load to the outside of the bra cup 3, the supportive power of the bra cup 3 would decrease, and the effect of firmly supporting and correcting the bust 1 even in normal conditions could be reduced.

[0056] A first groove 24 and a second groove 25 are V-shaped and formed in two locations on the inside longitudinal side of the first inner cup 20 facing the bra cup apex 4, in the direction that is the shortest distance toward the bra cup's verge line. The first groove 24 is located at the boundary between the first inner cup side portion 21 on the inside facing the bra cup apex 4 of the first inner cup 20 and the first inner cup lower portion 22, while the second groove 25 is located at the boundary between the first inner cup lower portion 22 on the inside facing the bra cup apex 4 of the first inner cup 20 and the first inner cup chest side center portion 23. The reason why there are two V-shaped grooves in these locations is that, in the first inner cup 20, considering the direction of load from the bust 1 (breast) in the circumferential direction due to the shape of the bust 1, the direction of longitudinal extension of the load from the bust 1 changes near the boundary between the first inner cup lower portion 22 and first inner cup side portion 21 and near the boundary between the first inner cup lower portion 22 and first inner cup chest side center portion 23. In the first inner cup under-bust section, longitudinal stretch G is primarily left-right stretching, while stretch F in the first inner cup side sections 22 and stretch K in the first inner cup chest-side center section 23 change to primarily longitudinal and vertical stretching in accordance with the shape of the bra cup 3. By providing a V-shaped groove at this boundary, the roles of the first inner cup 20 are divided. The side sections 21 of the first inner cup 20 are stretched primarily in response to load from the side sections of the bust. The first inner cup lower section 22 of the first inner cup 20 is stretched primarily in response to load from the under-bust (breast) section, and the chest-side center section 23 of the first inner cup 20 is stretched primarily in response to load from the bust apex (breast apex), which is the bra cup apex 4, to the bust-chest center section of the bra cup 3. These stretching actions make the three sections of the first inner cup 20 divided by the V-shaped groove less susceptible to load fluctuations from adjacent sections in response to changes in body behavior, and by using a wire 43 at the verge line 5 of the bra cup 3 in combination with bust correction, the bra cup 3 and first inner cup 20 do not slip away from the bust (breast) 1, and the structure allows stretching to concentrate on load fluctuations from the opposing bust 1. This structure provides targeted pressure to support the underside, sides and center of the bust, achieving ideal bust formation.

[0057] The first inner cup 20 of the present invention is divided into three sections by V-shaped grooves: the first inner cup side section 21, the first inner cup lower section 22, and the first inner cup chest side center section 23. Each section divided into three sections by the V-shaped grooves is further provided with two structures that are less susceptible to load fluctuations from adjacent sections and can stretch by concentrating on load fluctuations from the opposing bust 1. The choice of which structure to adopt at the time of design depends on the style of brassiere at the time.

[0058] As a first option, a groove 26 is provided on the skin side of the first inner cup 20 on the shortest line connecting the groove bottom of the first groove 24 to the verge line 5, and a groove 26 is also provided on the second groove 25 on the shortest line connecting the groove bottom to the verge line 5. As a second option, a long hole 27 is provided near the middle of the shortest line connecting the bottom of the first groove 24 of the first inner cup 20 to the verge line 5, and a long hole 27 is also provided on the second groove 25 on the shortest line connecting the bottom to the verge line 5.

[0059] In the first embodiment, which is the first option, a stripe groove 26 is provided on the skin side of the first inner cup 20 along the shortest line connecting the bottom of the first groove 24 to the verge line 5. A stripe groove 26 is also provided on the second groove 25 along the shortest line connecting the bottom of the groove to the verge line 5. This will be explained with reference to FIGS. 5 and 6. As shown in FIG. 5, the stripe groove is elongated, and as shown in the cross-sectional view of FIG. 7, it is narrow and shallow. As shown in FIG. 6, assuming that only the first inner cup lower portion 22 stretches due to changes in the shape of the brassiere wearer's bust 1 or bodily movement, the first inner cup lower portion 22 stretches in the direction of the arrow. The diagonal lines indicate the stretched state. At this time, the width of the first groove 24 narrows, and the stripe groove 26 widens, opening diagonally upward and becoming slightly twisted. This acts to minimize stretching of the adjacent first inner cup side portions 21, thereby minimizing the amount of stretching of the first inner cup side portions 21. Another advantage of providing the grooves 26 is that the grooves 26 act as starting points, making it easier for the first inner cup 20 to bend inwards in the circumferential direction to create a rounded shape that fits the bust 1, and the first inner cup 20 itself conforms to the shape of the bust 1, improving the wearing comfort of the brassiere 2. Furthermore, in Example 3, by using a wire 43 in combination with the verge line 5, the effect of the wire 43 on the verge line 5 located on the outer periphery of the bra cup means that the verge line 5 side of the bra cup 3 is firmly held by the wire 43, and the bust side is held down, so that the bra cup 3 fits snugly against the bust 1 without slipping. The grooves arranged on the shortest line connecting the bottom of the V-shaped groove of the first inner cup 20 to the verge line 5 prevent the bra cup 3 from slipping away from the bust 1 and firmly hold down the bust side with the wire 43, even if excessive load is placed on the first inner cup 20 from the bust 1 due to changes in body movement, thereby providing ideal stretching action for the first inner cup 20, and the bust 1 is always supported by stable pressure at the underside, sides and center of the chest, allowing for ideal bust formation.

[0060] In the second option, Example 2, a slot 27 is provided in the first groove 24 of the first inner cup 20 near the middle of the shortest line connecting the bottom to the verge line 5. The second groove 25 also has a slot 27 near the middle of the shortest line connecting the bottom to the verge line 5. This will be explained with reference to Figures 8 and 9. As shown in Figure 8, the slot 27 is an elongated, oval-shaped hole. As shown in Figure 9, assuming that only the first inner cup lower portion 22 stretches due to a change in the shape of the brassiere wearer's bust 1 or bodily movement, the first inner cup lower portion 22 stretches in the direction of the arrow. The diagonal lines indicate the stretched state. At this time, the width of the first groove 24 narrows. The slot 27 widens, opening diagonally upward, minimizing stretch of the adjacent first inner cup side portion 21. This minimizes stretch of the first inner cup side portion 21. Furthermore, in Example 3, by using a wire 43 at the verge line 5 in combination with the wire, the wire 43 at the verge line 5 located on the periphery of the bra cup 3 ensures that the verge line 5 side of the bra cup 3 is firmly held down by the wire 43 against the bust 1 without slipping, and the bra cup 3 fits snugly against the bust 1 without slipping. The long hole 27 located near the middle of the shortest line connecting the bottom of the V-shaped groove of the first inner cup 20 to the verge line 5 prevents the verge line 5 side of the bra cup 3 from slipping away from the bust 1 and firmly holds down the bust 1 side by the wire 43, even if excessive load is applied from the bust 1 to the first inner cup 20 due to changes in body movement, so that the first inner cup 20 is stretched ideally, and the bust 1 is always supported by a stable pressure at the underside, sides and center of the bust, achieving ideal bust formation.

[0061] The only difference between Example 1 and Example 2 and Example 3 is whether or not wires 43 are provided on the verge line 5 located on the periphery of the bra cups 3 of the brassiere 2. Some women who wear brassieres 2 dislike the tightness of the wires 43 attached to the verge line 5, while others prefer brassieres 2 with wire functions 43 because the wires 43 attached to the verge line 5 provide increased holding power and have a bust-correcting effect of "pushing" and "lifting" the bust, and those who are concerned about the increased support provided by the wires 31 and the bra cups 3 slipping away from the bust (breasts) 1 as their body movements change. In order to accommodate both types of people, the present invention proposes that Examples 1 and 2 are appropriate for those who dislike the tightness of the wires 43 attached to the verge line 5 or who dislike the wires 43, while Example 3 is proposed for those who prefer a bra that provides the bust-shaping and correcting effect of the wires 43 attached to the verge line 5.

[0062] The present invention is not limited to the brassiere 2, but may also be applied to clothing having bra cups, such as body suits, bra slips, bra camisoles, and swimwear. [Industrial Applicability]
