Garment with bra cups

Abstract

To provide a garment having bra cups that can maintain an ideal bust line by improving an appropriate bust-correcting effect produced by an inner cup provided within the bra cup.SOLUTION: A first inner cup 30 made of an elastic material is provided within a bra cup 3 so as to extend from a bust middle portion to a bust lower portion along an underarm and a bust root line 5 from a shoulder-side top to a chest-side edge 11. 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. In combination therewith, a second inner cup 40 made of an elastic material is provided on the inner side adjacent to the skin side of the first inner cup, the second inner cup being larger than the first inner cup and sized to fit within the bra cup. In this combined structure using the first and second inner cups, the first inner cup is divided into three regions, namely, a side region 31, a lower region 32 and a central chest region 33, 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] The present invention relates to women's clothing with conical bra cups that encase and correct each breast independently, as typified by a brassiere, and includes a first inner cup made of a stretchy material that runs from the shoulder top to the side and along the verge line, two longitudinal grooves on the inside of the first inner cup extending from the apex toward the verge line, which divide the inner cup into three sections—the side sections, the lower section, and the center section toward the chest—that encase and correct the breasts within the bra cup, and a second inner cup made of a stretchy material that is larger than the first inner cup and fits into the bra cup, located adjacent to the inside of the first inner cup (the skin-facing side), and also includes a wire within the verge line to encase and correct the breasts 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.

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

[0010] According to the first invention A second inner cup made of stretchable material is provided adjacent to the inside of the first inner cup, which faces the skin, and is larger than the first inner cup so that it can fit into the bra cup. The second inner cup is sewn to the bra cup only at its outer periphery. The second inner cup has greater stretchability than the first inner cup, making it easier to stretch. By making the stretchability of the first and second inner cups different, the first inner cup acts primarily on the section (location) of the bra cup that is most susceptible to stress from the bust. A material with less stretchability than the second inner cup is used to firmly support the bust within the bra cup, and the second inner cup is made of a highly stretchable material with a high stretchability, which softly covers the part of the bra cup that acts on the bust. This creates a synergistic effect, alleviating the feeling of oppression and discomfort caused by excessive tightness around the top of the bust, while allowing the bra cup to adapt smoothly to changes in body movement without floating. The bust lifting effect is also improved, bringing the bust together from the left and right and firmly supporting the lower part of the bust, allowing the wearer to maintain a beautiful silhouette without feeling uncomfortable even when moving. The first inner cup is provided with a second inner cup made of a stretchable material, which is larger than the first inner cup and fits into the bra cup, adjacent to the inside of the first inner cup that is the skin side. The first inner cup has a first groove and a second groove at two locations on the inside of the lengthwise direction facing the apex of the bra cup, as grooves that are oriented in the direction that is the shortest distance toward the verge line of the bra cup. The first inner cup is provided with a first groove and a second groove that are oriented in the direction that is the shortest distance toward the verge line of the bra cup, and the first inner cup is provided with a first groove and a second groove that are oriented in the direction that is the shortest distance toward the verge line of the bra cup from the top of the shoulder side to the chest side edge of the bra cup along the verge line. When the center is divided into three sections, the first groove is provided at the boundary between the side 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 first inner cup on the chest side. By making both the first groove and the second groove V-shaped, the first inner cup is roughly divided into three sections: the side of the first inner cup, the lower part of the first inner cup, and the center part of the first inner cup on the chest side. This prevents excessive interference from adjacent sections due to changes in the wearer's body movements, and improves the alignment of the first inner cup and the second inner cup. The synergistic effect of the cups allows them to stretch and respond to the load from each opposing bust, and furthermore, a bra cup has a second inner cup made of stretchable material that is larger than the first inner cup and fits into the bra cup adjacent to the inside of the first inner cup, which is the skin side.By providing strip 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 strip grooves 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 first and second grooves.The synergistic effect of the first and second inner cups in each section allows them to stretch and respond to the load from the opposing bust, and the bra cups can maintain appropriate pressure on the bust.

[0011] In the first aspect of the invention, according to the second aspect, the holding power 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 power 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, a second inner cup made of a stretchable material is provided adjacent to the inside of the first inner cup, which is the skin side, and is larger than the first inner cup so that it can fit into the bra cup. The second inner cup is sewn to the bra cup only at the outer periphery of the second inner cup. The second inner cup has higher stretchability than the first inner cup, making it easier to stretch. By making the stretchability of the first inner cup and the second inner cup different, the first inner cup acts primarily on the section (location) in the bra cup that receives the most stress from the bust, and the second inner cup is made of a material with a lower stretchability than the second inner cup, and fits into the bra cup. The bra cups firmly support the bust, and the second inner cup, made of a highly stretchable material, softly covers the area where the bra cups work on the bust. This creates a synergistic effect, alleviating the feeling of oppression and discomfort caused by excessive tightness on the bust top, while allowing the bra cups to adapt smoothly to changes in body movement without floating. It also improves the lift-up effect of the bust, bringing the bust together from both sides and firmly supporting the lower part of the bust, allowing the wearer to maintain a beautiful silhouette without discomfort even when moving. The second inner cup, which is adjacent to the inside of the first inner cup that is the skin side, is larger than the first inner cup. The first inner cup is provided with a second inner cup made of a stretchable material sized to fit into the bra cup, and has a first groove and a second groove at two locations on the inside in the longitudinal direction facing the apex of the bra cup, which are grooves that face in the shortest direction toward the verge line of the bra cup. 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 on 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. The first and second grooves are both V-shaped, which divides the first inner cup into three sections: the sides of the first inner cup, the bottom of the first inner cup, and the center of the first inner cup on the chest side. This prevents excessive interference from the adjacent sections due to changes in the wearer's body movements, and the synergistic effect of the first and second inner cups allows them to respond to and stretch the load from the opposing breasts. Furthermore, by providing long holes near the middle of the shortest line connecting the bottom 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 in each groove work together to cushion the load from the bust between adjacent sections, preventing excessive interference from adjacent sections separated by the first and second grooves due to changes in the wearer's body behavior, and the synergistic effect of the first and second inner cups in each section allows them to respond to and stretch the load from the opposing bust, maintaining even pressure on the bust from the bra cups.

[0013] In the third aspect of the invention, according to the fourth aspect, the holding power 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 power provided by the wire is increased, preventing the bra cups from slipping off the bust (breasts) as the body's movements change.

[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. In addition, in the present invention, when expressing the high or low stretchability (elasticity) of the materials used for the first inner cup 20 and the second inner cup 30, 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.

[0017] The brassiere 2 shown in Figs. 1 and 3 of Examples 1 and 2 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 brassiere 2 is shown on the left breast side. 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-side center portion 23, which are separated by the second groove. Fig. 4 is an explanatory diagram of the section between MP in Fig. 1 when the first inner cup 20 is installed in the bra cup of Example 1. In this invention, the base line of the bust of the brassiere 2 is referred to as the verge line 5. In Example 1 and Example 2, where a wire 45 is not provided on the verge line 5 of the brassiere 2, a shaping material 10 is provided on the verge line 5. The shaping material 10 provided on the brassiere-side verge line is referred to as the shaping material. The structure of the brassiere-side verge line shaping material 10 is formed by providing a core material in the center and folding the fabric of the bra cup 3 over and over. Explanation of the brassiere-side verge line shaping material 10 will be omitted. In Example 3, a wire 45 is provided on the brassiere-side verge line shaping material 10. The shaping material provided on the verge line 5 of the brassiere 2 is referred to as the brassiere-side verge line shaping material 10. Explanation of the brassiere-side verge line shaping material 10 will be omitted. In Example 3, a wire 45 is provided instead of the brassiere-side verge line shaping material 10. Figure 5 is an explanatory diagram of the positional relationship between the first groove and the linear groove according to Example 1. Fig. 6 is an explanatory diagram of the action of the first groove and the linear groove when excessive load is concentrated from the bust 1 to the first inner cup lower part 32 according to Example 1. Fig. 8 is an explanatory diagram of the positional relationship between the first groove and the elongated hole according to Example 2. Fig. 9 is an explanatory diagram of the action of the first groove and the elongated hole when excessive load is concentrated from the bust 1 to the first inner cup lower part 32 according to Example 2. Generally, molded brassieres are provided with a large number of holes or slits (through holes) that penetrate the inner cup to improve the breathability of the inner cup.In the drawings of Examples 1, 2, and 3, this is referred to as a vent hole 18. A description of this vent hole 18 alone will be omitted.

[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. The bra cup 3 is conically shaped to encase the bust 1, and includes multiple sheets of fiber fabric. A first inner cup 20 is provided at the center of the multiple sheets of fabric. The first inner cup 30 within the bra cup 3 extends from the shoulder-side top 8 of the bra cup 3 along the verge line 5, which is the base line of the bust 1 of the bra cup 3, to the chest-side edge 11 of the bra cup 3. The width of the first inner cup 30 at its widest point is within two-thirds of the distance from the verge line 5 to the apex 4 of the bra cup. A second inner cup 40, larger than the first inner cup 30 but large enough to fit within the bra cup 3, is provided adjacent to the inside of the first inner cup 30, which faces the skin. As shown in FIG. 4, when viewed from the bust 1, the bra cup lining fabric 42 is followed by the second inner cup 40, the first inner cup 30, and then the bra cup outer fabric 41.

[0022] The first inner cup 30 and the second inner cup 40 can be made of soft synthetic resin foam such as polyurethane foam, latex foam, or nylon polyurethane foam. The appropriate material is determined at the time of design depending on the shape of the brassiere. It is most effective to use the same material for both the first inner cup 30 and the second inner cup 40.

[0023] The first inner cup 30 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 30 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 30 that contacts the verge line 5 to the bra cup 2, the first inner cup 30 itself is prevented from stretching and protruding beyond the verge line 5. By sewing the section of the first inner cup 30 that contacts the chest edge 11 of the bra cup 3 to the bra cup 3, the first inner cup 30 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 30, the section (location) facing the apex 4 of the bra cup 3 is not sewn to the bra cup 3.

[0024] In Example 1, a second inner cup 40 is provided adjacent to the inside of the first inner cup 30, which is the skin-facing side. The second inner cup 40 is larger than the first inner cup 30 and is sized to fit into the bra cup 3. The second inner cup 40 is sewn to the bra cup 3 only at its outer periphery. The second inner cup 40 is designed to swell outward as a whole, in order to accommodate the shape of the bust 1 of the wearer of the brassiere 2 or load fluctuations while wearing the brassiere 2, and therefore the second inner cup 40 is sewn to the bra cup 3 only at its outer periphery. Therefore, as shown in Figure 1, the sewing of the second inner cup 40 to the bra cup 3 starts from the shoulder-side top 8 of the bra cup 3, then goes to the stretch tape 9, then to the verge line 5 and the chest-side edge 11 of the bra cup 3, and ends at the shoulder-side top 8, the same as the starting point.

[0025] Two V-shaped grooves are provided on the inside longitudinal side of the first inner cup 30 facing the bra cup apex 4, which is not sewn to the bra cup 3, in the direction that is the shortest distance toward the bra cup's verge line. A first groove 34 and a second groove 35 are provided in this order from the shoulder-side apex of the bra cup 2. The first groove 34 is located at the boundary between the first inner cup side portion 31 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup lower portion 32. The second groove 35 is located at the boundary between the first inner cup lower portion 32 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup chest-side center portion 33. Because neither the first groove 34 nor the second groove 35 is sewn to the second inner cup 40, the structure can instantly respond to load changes and stretch without being affected by the second inner cup 40.

[0026] The first groove 34 and the second groove 35, which are provided in two longitudinally inner locations on the first inner cup 30 facing the bra cup apex 4, have the same shape and depth. The first groove 34 and the second groove 35 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 34 and the second groove 35 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 to C cups, D cups, E cups, and F cups, the depth approaches a maximum value of 1.5 mm.

[0027] A groove 36 is provided on the skin side of the first inner cup 30 on the shortest line connecting the bottom of the first groove 34 to the verge line 5. Furthermore, a groove 36 is also provided on the shortest line connecting the bottom of the groove to the verge line 5 for the second groove 35. The width of the groove 36 is determined at the time of design based on the cup size and shape of the intended brassiere 2. For a small bra cup 3 such as an A cup, the width of the groove 36 may be narrow, but as the bra cup 3 size increases from a C cup to a D cup, the width of the groove 36 tends to become wider. Because the groove 36 of the first inner cup 30 is not sewn to the second inner cup 40, it is structured to be able to instantly respond and stretch to load changes without being affected by the second inner cup 40.

[0028] A second inner cup 40, the same size as the skin-facing side of the bra cup 3, is provided on the skin-facing side of the first inner cup 30. The second inner cup 40 is similar to inner cups typically used in molded brassieres. Like inner cups typically used in molded brassieres, the second inner cup 40 is sewn to the bra cup 3 only at the point where it contacts the outer periphery. However, the second inner cup 40 has a higher stretchability than the first inner cup 30, making it easier to stretch. In this invention, a higher stretchability means that the material is more likely to stretch when a load is applied, while a lower stretchability means that the material is less likely to stretch even when a load is applied. By using a combined method in which the stretchability of the first inner cup 30 is lower than that of the second inner cup 40, making it less stretchable than the second inner cup 40, the disadvantage of the inner cup is turned into an advantage, thereby improving the bust support that is a drawback of molded brassieres. [Example]

[0029] 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. The bra cup 3 is conically shaped to encase the bust 1, and includes multiple layers of fabric. A first inner cup 30 is located at the center of the multiple layers. The first inner cup 30 extends from the shoulder-side top 8 of the bra cup 3 along the verge line 5, which is the base line of the bust 1 of the bra cup 3, to the chest-side edge 11 of the bra cup 3. The width of the first inner cup 30 at its widest point is within two-thirds of the distance from the verge line 5 to the apex 4 of the bra cup. A second inner cup 40, larger than the first inner cup but sized to fit within the bra cup, is located adjacent to the inside of the first inner cup 30, which faces the skin. As shown in FIG. 4, when viewed from the bust, the bra cup lining 42 is followed by the second inner cup 40, the first inner cup 30, and then the bra cup outer fabric 41.

[0030] The first inner cup 30 and the second inner cup 40 can be made of soft synthetic resin foam such as polyurethane foam, latex foam, or nylon polyurethane foam. The appropriate material is determined at the time of design depending on the shape of the brassiere. It is most effective to use the same material for both the first inner cup 30 and the second inner cup 40.

[0031] The first inner cup 30 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 30 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 30 that contacts the verge line 5 to the bra cup 2, the first inner cup 30 itself is prevented from stretching and protruding beyond the verge line 5. By sewing the section of the first inner cup 30 that contacts the chest edge 11 of the bra cup 3 to the bra cup 3, the first inner cup 30 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 30, the section (location) facing the apex 4 of the bra cup 3 is not sewn to the bra cup 3.

[0032] In the second embodiment, a second inner cup 40, which is larger than the first inner cup and fits into the bra cup, is provided adjacent to the inside of the first inner cup 30, which is the skin side. The second inner cup 40 is sewn to the bra cup 3 only at the outer periphery of the second inner cup 40. The second inner cup 40 is designed to expand outward as a whole to accommodate the shape of the wearer's bust or to expand outward toward the outer fabric 41 of the brassiere in response to changes in load during wear, so the second inner cup 40 is sewn to the bra cup 3 only at the outer periphery of the second inner cup 40. Therefore, as shown in FIG. 1 , the sewing of the second inner cup 40 to the bra cup 3 starts from the shoulder side top 8 of the bra cup 3, then goes to the stretch tape 9, then to the verge line 5 and the chest side edge 11 of the bra cup 3, and ends at the shoulder side top 8, the same as the starting point.

[0033] Two V-shaped grooves are provided on the inside longitudinal side of the first inner cup 30 facing the bra cup apex 4, which is not sewn to the bra cup 3, in the direction that is the shortest distance toward the bra cup's verge line. A first groove 34 and a second groove 35 are provided in this order from the shoulder-side apex of the bra cup 2. The first groove 34 is located at the boundary between the first inner cup side portion 31 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup lower portion 32. The second groove 35 is located at the boundary between the first inner cup lower portion 32 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup chest-side center portion 33. Because neither the first groove 34 nor the second groove 35 is sewn to the second inner cup 40, the structure can instantly respond to load changes and stretch without being affected by the second inner cup 40.

[0034] The first groove 34 and the second groove 35, which are provided in two longitudinally inner locations on the first inner cup 30 facing the bra cup apex 4, have the same shape and depth. The first groove 34 and the second groove 35 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 34 and the second groove 35 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 to C cups, D cups, E cups, and F cups, the depth approaches a maximum value of 1.5 mm.

[0035] An elongated hole 37 is provided in the first inner cup 30 near the middle of the shortest line connecting the bottom of the first groove 34 to the verge line 5. Similarly, an elongated hole 37 is provided in the second groove 35 near the middle of the shortest line connecting the bottom of the second groove 35 to the verge line 5. The length and number of elongated holes 37 are determined at the time of design based on the cup size and shape of the brassiere 2 to be designed. For a small bra cup 3, such as an A cup, the length of the elongated hole 37 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 length of the elongated holes 37 increases and multiple holes are required. The elongated holes 37 in the first inner cup 30 are not sewn to the second inner cup 40, allowing the elongated holes 37 to instantly respond to load changes and expand without being affected by the second inner cup 40.

[0036] A second inner cup 40, the same size as the skin-facing side of the bra cup 3, is provided on the skin-facing side of the first inner cup 30. The second inner cup 40 is similar to inner cups typically used in molded brassieres. Like inner cups typically used in molded brassieres, the second inner cup 40 is sewn to the bra cup 3 only at the point where it contacts the outer periphery. However, the second inner cup 40 has a higher stretchability than the first inner cup 30, making it easier to stretch. In this invention, a higher stretchability means that the material is more likely to stretch when a load is applied, while a lower stretchability means that the material is less likely to stretch even when a load is applied. By using a combined method in which the stretchability of the first inner cup 30 is lower than that of the second inner cup 40, making it less stretchable than the second inner cup 40, the disadvantage of the inner cup is turned into an advantage, thereby improving the bust support that is a drawback of molded brassieres.

[0037] The following describes the operation and effects of the present embodiment described in Examples 1 and 2. The brassiere configurations described in Examples 1 and 2 are primarily intended to improve the bust support and hold of a molded brassiere, a weakness of molded brassiere bras, in which the bra cups 3 and belt 6 of the brassiere 2 having a second inner cup 40 are made of a highly stretchable material, by applying a first inner cup 30. This aims to improve the bust support and hold while maintaining the gentle, enveloping feeling that is the advantage of molded brassiere bras. At the same time, the present invention is not limited to the type of brassiere 2. It also aims to improve the bust support and hold by using the first inner cup 30 and second inner cup 40 in combination with regular brassies or general clothing with bra cups, in which the general bust 1 undersize is 65, 70, 75, or 80 and the bra cup 3 is sized A, B, C, D, E, or F. This aims to improve the overall bust (breast) support while maintaining the gentle, enveloping feeling that is the advantage of molded brassiere bras.

[0038] When wearing the brassiere 2, the areas in the bra cup 3 that receive the greatest stress 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 receive the greatest stress from the bust 1 when wearing the brassiere 2, and the first inner cup 30 is provided in a section that starts from the shoulder-side top 8 of the bra cup 3, goes through the stretch tape 9, 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 30 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 30 encases the bust from the shoulder top 8 of the bra cup through the stretch tape 9 along the verge line 5 to the chest edge 11 of the bra cup in the middle and lower sections, and by using the second inner cup 40 in combination, the first inner cup 30 applies pressure to the corresponding lower section 32 of the first inner cup, the side section 33 of the first inner cup and the center section 33 of the chest side of the first inner cup, thereby achieving ideal bust formation in comparison with a molded brassiere.

[0039] The side of the first inner cup 30 facing the bust apex 4 is not sewn to the bra cup 3. When a load fluctuation occurs on the first inner cup 30 due to a change in the wearer's posture or other behavior, the bra cup 3 either stretches outward to accommodate the excessive load from the bust 1 to the bra cup 3, or stretches toward the bra cup apex 4 where the first inner cup 30 is not present. The side of the first inner cup 30 facing the bra cup apex 4 is not sewn to the bra cup 3. At the same time, the side of the first inner cup 30 facing the bra cup apex 4 is not sewn to the second inner cup 40, allowing it to instantly respond and stretch to load fluctuations without being affected by the second inner cup 40. Therefore, the first inner cup 30 stretches toward the bra cup apex 4 in response to load fluctuations and returns to its original state when the load returns to normal. The area of ​​the bra cup 3 that experiences the least load from the bust (breast) itself is the upper part 15 of the bust 1. If the first inner cup 30's stretching action could release excess pressure toward the upper bust 1 section 15 when the bust is subjected to excessive strain, then using the second inner cup in combination would provide targeted pressure on the molded brassiere, supporting the mid-bust 16 and lower bust 17 sections from the sides to the lower bust and toward the center of the bust, achieving ideal bust shaping. The second inner cup 40, which corresponds to a conventional inner cup, alone is structurally difficult to improve support for the mid-bust 16 and lower bust 17 sections, which bear the greatest strain from the bust itself within the bra cup 3. If the second inner cup 40, which corresponds to a conventional inner cup, were to be made less stretchable in order to improve its support, it could instead increase the sense of pressure and intimidation felt by the wearer's bust, potentially reducing comfort. The combined use of the first inner cup 30 and second inner cup 40 focuses on this point. The combined use of the first inner cup 30 and the second inner cup 40 increases the degree of freedom in designing a brassiere to reduce the feeling of pressure and intimidation on the bust and to improve comfort.

[0040] Furthermore, the first inner cup 30 has a first groove 34 and a second groove 35, 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 34 is located at the boundary between the first inner cup side portion 31 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup under-bust portion 32, while the second groove 35 is located at the boundary between the first inner cup under-bust portion 32 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup's chest-side center portion 33. As shown in FIG. 6 , if a load fluctuation occurs on the first inner cup 30 due to a change in the wearer's posture or other behavior while wearing the brassiere 2, the first inner cup 30 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 30 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 longitudinally inner side facing the bra cup apex 4, making it difficult for the first inner cup 30 to stretch toward the bra cup apex 4. This would make it impossible for the first inner cup 30 to absorb the excessive load. If the first inner cup 30 were made more stretchable by using a material with increased stretchability 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.

[0041] A first groove 34 and a second groove 35 are V-shaped and extend in the shortest direction toward the bra cup's verge line at two locations on the inside longitudinal side of the first inner cup 30 facing the bra cup apex 4, with the first groove 34 located at the boundary between the inside first inner cup side portion 31 facing the bra cup apex 4 of the first inner cup 30 and the first inner cup lower portion 32, while the second groove 35 is located at the boundary between the inside first inner cup lower portion 32 facing the bra cup apex 4 of the first inner cup 30 and the chest side center portion 33 of the first inner cup. The reason why there are two V-shaped grooves at these locations is that, in the first inner cup 30, considering the direction of load in the circumferential direction due to the shape of the bust 1 (breast), the direction (orientation) of load from the bust 1 stretches in the longitudinal direction changes near the boundary between the first inner cup lower portion 32 and the first inner cup side portion 31 and near the boundary between the first inner cup lower portion 32 and the first inner cup chest side center portion 33. In the first inner cup lower portion 32, longitudinal stretch G is primarily a left-right stretch, while stretch F in the first inner cup side portion 32 and stretch K in the first inner cup chest side center portion 33 change to primarily longitudinal and vertical stretch 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 30 are divided. The first inner cup side portion 31 is stretched primarily in response to load from the side of the bust (breast), the first inner cup lower portion 32 is stretched primarily in response to load from the lower part of the bust (breast), and the first inner cup chest side center portion 33 is stretched primarily in response to load from the chest side center of the bust (breast). These stretching actions make the three sections of the first inner cup 30 divided by the V-shaped grooves as insensitive to load fluctuations from adjacent sections as possible, allowing stretching to be concentrated on load fluctuations from the opposing bust 1. This structure allows for targeted pressure to be applied to the underside of the bust, the sides of the bust and the center of the chest, resulting in ideal bust formation.

[0042] The first inner cup 30 of the present invention is divided into three sections by V-shaped grooves: the first inner cup side section 31, the first inner cup lower section 32, and the first inner cup chest side center section 33. 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.

[0043] As a first option, a groove 36 is provided on the skin side of the first inner cup 30 of Example 1 on the shortest line connecting the groove bottom of the first groove 34 to the verge line 5, and a groove 36 is also provided on the second groove 35 on the shortest line connecting the groove bottom to the verge line 5. As a second option, a long hole 37 is provided near the middle of the shortest line connecting the bottom of the first groove 34 of the first inner cup 30 to the verge line 5, and a long hole 37 is also provided on the second groove 35 on the shortest line connecting the bottom to the verge line 5.

[0044] In the first embodiment, which is the first option, a stripe groove 36 is provided on the skin side of the first inner cup 30 on the shortest line connecting the bottom of the first groove 34 to the verge line 5, and a stripe groove 36 is also provided on the shortest line connecting the bottom of the second groove 35 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 32 stretches due to changes in the shape of the brassiere wearer's bust 1 or bodily behavior, the first inner cup lower part 32 stretches in the direction of the arrow. The diagonal lines indicate the stretched state. At this time, the width of the first groove 34 narrows, and the width of the stripe groove 36 widens, opening diagonally upward and becoming slightly twisted, which acts to prevent the adjacent first inner cup side portion 31 from stretching as much as possible, minimizing the amount of stretch of the first inner cup side portion 31. Another advantage of providing the stripe groove 36 is that by providing the stripe groove 36, the first inner cup 30 itself becomes a base point and easily creates a rounded shape circumferentially inward to fit the bust 1, so that the first inner cup 30 itself conforms to the shape of the bust 1, improving the wearing comfort of the brassiere 2.

[0045] In the second embodiment, a slot 37 is provided in the first groove 34 of the first inner cup 30 near the middle of the shortest line connecting the bottom of the first groove 34 to the verge line 5. The second groove 35 also has a slot 37 near the middle of the shortest line connecting the bottom of the first groove 34 to the verge line 5. This will be explained with reference to FIGS. 8 and 9. As shown in FIG. 8, the slot 37 is an elongated, oval-shaped hole. As shown in FIG. 9, assuming that only the first inner cup lower portion 32 stretches due to a change in the shape of the brassiere wearer's bust 1 or bodily movement, the first inner cup lower portion 32 stretches in the direction of the arrow. The diagonal lines indicate the stretched state. At this time, the width of the first groove 34 narrows. The slot 37 widens, opening diagonally upward, minimizing the stretch of the adjacent first inner cup side portion 31. This minimizes the amount of stretch of the first inner cup side portion 31. [Example]

[0046] The only difference between Example 1 and Example 2 and Example 3 is whether or not a wire 45 is provided at the waistline 5 located on the periphery of the brassiere cup 3 of the brassiere 2. Therefore, Example 1 is used as a representative example in Example 3. Therefore, all the reference numerals in the drawings are the same as those in Example 1 except for the wire 45.

[0047] 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 3. The bra cup 3 is cone-shaped and encases the bust 1. A first inner cup 20 is provided at the center of multiple layers of fiber fabric. The first inner cup 30 within the bra cup 3 extends from the shoulder-side top 8 of the bra cup 3 along the verge line 5, which is the base line of the bust 1 of the bra cup 3, to the chest-side edge 11 of the bra cup 3. The width of the first inner cup 30 at its widest point is within two-thirds of the distance from the verge line 5 to the apex 4 of the bra cup. A second inner cup 40, larger than the first inner cup 30 but large enough to fit within the bra cup 3, is provided adjacent to the inside of the first inner cup 30, which faces the skin. As shown in FIG. 4, when viewed from the bust 1, the bra cup lining fabric 42 is followed by the second inner cup 40, the first inner cup 30, and then the bra cup outer fabric 41.

[0048] The first inner cup 30 and the second inner cup 40 can be made of soft synthetic resin foam such as polyurethane foam, latex foam, or nylon polyurethane foam. The appropriate material is determined at the time of design depending on the shape of the brassiere. It is most effective to use the same material for both the first inner cup 30 and the second inner cup 40.

[0049] The first inner cup 30 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 30 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 30 that contacts the verge line 5 to the bra cup 2, the first inner cup 30 itself is prevented from stretching and protruding beyond the verge line 5. By sewing the section of the first inner cup 30 that contacts the chest edge 11 of the bra cup 3 to the bra cup 3, the first inner cup 30 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 30, the section (location) facing the apex 4 of the bra cup 3 is not sewn to the bra cup 3.

[0050] In Example 3, a second inner cup 40 is provided adjacent to the inside of the first inner cup 30, which is the skin-facing side. The second inner cup 40 is larger than the first inner cup 30 and is sized to fit into the bra cup 3. The second inner cup 40 is sewn to the bra cup 3 only at its outer periphery. The second inner cup 40 is designed to swell outward as a whole, in order to accommodate the shape of the bust 1 of the wearer of the brassiere 2 or to accommodate load fluctuations while wearing the brassiere 2, and therefore the second inner cup 40 is sewn to the bra cup 3 only at its outer periphery. Therefore, as shown in Figure 1, the sewing of the second inner cup 40 to the bra cup 3 starts from the shoulder-side top 8 of the bra cup 3, then goes to the stretch tape 9, then to the verge line 5 and the chest-side edge 11 of the bra cup 3, and ends at the shoulder-side top 8, the same as the starting point.

[0051] Two V-shaped grooves are provided on the inside longitudinal side of the first inner cup 30 facing the bra cup apex 4, which is not sewn to the bra cup 3, in the direction that is the shortest distance toward the bra cup's verge line. A first groove 34 and a second groove 35 are provided in this order from the shoulder-side apex of the bra cup 2. The first groove 34 is located at the boundary between the first inner cup side portion 31 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup lower portion 32. The second groove 35 is located at the boundary between the first inner cup lower portion 32 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup chest-side center portion 33. Because neither the first groove 34 nor the second groove 35 is sewn to the second inner cup 40, the structure can instantly respond to load changes and stretch without being affected by the second inner cup 40.

[0052] The first groove 34 and the second groove 35, which are provided in two longitudinally inner locations on the first inner cup 30 facing the bra cup apex 4, have the same shape and depth. The first groove 34 and the second groove 35 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 34 and the second groove 35 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 to C cups, D cups, E cups, and F cups, the depth approaches a maximum value of 1.5 mm.

[0053] A groove 36 is provided on the skin side of the first inner cup 30 on the shortest line connecting the bottom of the first groove 34 to the verge line 5. Furthermore, a groove 36 is also provided on the shortest line connecting the bottom of the groove to the verge line 5 for the second groove 35. The width of the groove 36 is determined at the time of design based on the cup size and shape of the intended brassiere 2. For a small bra cup 3 such as an A cup, the width of the groove 36 may be narrow, but as the bra cup 3 size increases from a C cup to a D cup, the width of the groove 36 tends to become wider. Because the groove 36 of the first inner cup 30 is not sewn to the second inner cup 40, it is structured to be able to instantly respond and stretch to load changes without being affected by the second inner cup 40.

[0054] A second inner cup 40, the same size as the skin-facing side of the bra cup 3, is provided on the skin-facing side of the first inner cup 30. The second inner cup 40 is similar to inner cups typically used in molded brassieres. Like inner cups typically used in molded brassieres, the second inner cup 40 is sewn to the bra cup 3 only at the point where it contacts the outer periphery. However, the second inner cup 40 has a higher stretchability than the first inner cup 30, making it easier to stretch. In this invention, a higher stretchability means that the material is more likely to stretch when a load is applied, while a lower stretchability means that the material is less likely to stretch even when a load is applied. By using a combined method in which the stretchability of the first inner cup 30 is lower than that of the second inner cup 40, making it less stretchable than the second inner cup 40, the disadvantage of the inner cup is turned into an advantage, thereby improving the bust support that is a drawback of molded brassieres.

[0055] A wire 45 is attached to the verge line 5, which is the base line of the bust 1 located on the periphery of the bra cup 3, for the purpose of supporting and holding the bust (breast) 1. The wire 45 can be either circular or oval in shape to achieve a holding effect. Considering the pressure exerted by the wire 45 on the bust 1, the load exerted by the bust 1 on the wire 45, and the comfort of wearing the bra 2, an oval shape is the most appropriate shape for the wire 45. The wire 45 is determined based on the shape and size of the bra cup 3, the price of the bra 2 itself, and the current design. The material of the wire 45 is selected from metal wires commonly used in bra 2, such as stainless steel, amorphous alloy, and shape-memory alloy, or flexible materials such as flexible plastics, fiber-reinforced plastics, and resins. The wire 45 is determined based on the shape and size of the bra cup 3, the price of the bra 2 itself, and the current design. The wire 45 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.

[0056] 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 45 is provided at the vestibule 5 of the brassiere 2. The advantages of providing the wire 45 at the vestibule 5 of the brassiere 2 include an increased holding power due to the effect of the wire 45, which has the effect of correcting the bust 1 by "pushing" and "lifting" the bust 1, and an increased support power due to the wire 45, which can prevent the bra cups 3 from slipping off the bust (breasts) 1 due to changes in body movement.

[0057] When wearing a brassiere 2, the areas in the bra cup 3 that receive the greatest stress 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, which receive the most stress from the bust 1 when wearing a brassiere 2, and the first inner cup 30 is provided in a section that starts from the shoulder-side top 8 of the bra cup 3, passes through the stretch tape 9, and 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 30 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 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 attached to the verge line, and the stretchable first inner cup 30 wraps around the bust from the shoulder top 8 of the bra cup through the stretch tape 9 along the verge line 5 to the middle and lower parts of the bust, and by using the second inner cup 40 in combination, the first inner cup 30 supports the corresponding lower part 32 of the first inner cup, the side part 33 of the first inner cup, and the center part 33 of the chest side of the first inner cup with targeted pressure, compared to a molded brassiere, and by using the wire 45 attached to the verge line 5, the bust can be "pushed together" or "lifted" to achieve the ideal bust shape.

[0058] The side of the first inner cup 30 facing the bust apex 4 is not sewn to the bra cup 3. When a load fluctuation occurs on the first inner cup 30 due to a change in the wearer's posture or other behavior, the bra cup 3 either stretches outward to accommodate the excessive load from the bust 1 to the bra cup 3, or stretches toward the bra cup apex 4 where the first inner cup 30 is not present. The side of the first inner cup 30 facing the bra cup apex 4 is not sewn to the bra cup 3. At the same time, the side of the first inner cup 30 facing the bra cup apex 4 is not sewn to the second inner cup 40, allowing it to instantly respond and stretch to load fluctuations without being affected by the second inner cup 40. Therefore, the first inner cup 30 stretches toward the bra cup apex 4 in response to load fluctuations and returns to its original state when the load returns to normal. The area of ​​the bra cup 3 that experiences the least load from the bust (breast) itself is the upper part 15 of the bust 1. If excessive pressure is applied from the bust (breasts), and the wire 45 attached to the verge line 5 shown in Example 3 keeps the bra cup 3 in close contact with the bust without slipping, and the stretching action of the first inner cup 30 allows the pressure to be released toward the upper bust 15, then by using the second inner cup in combination, the molded brassiere can apply targeted pressure to support the bust from the sides to the lower part of the bust and the center of the chest, from the middle bust 16 to the lower bust 17, achieving ideal bust shaping. The holding and support power of the wire 45 attached to the verge line 5 allows the bra cup 3 to adapt to changes in body movement, preventing the bra cup 3 from slipping from the bust 1 and improving the stability and comfort of the bra cup 3. The second inner cup 40, which corresponds to a conventional inner cup, alone is structurally difficult to improve the hold of the middle and lower bust 16 and 17, which are the parts of the bra cup 3 that bear the greatest pressure from the bust itself. If the second inner cup 40, which corresponds to the conventional inner cup, is made less stretchy in order to improve its holding power, it may actually increase the feeling of pressure and intimidation on the wearer's bust, reducing comfort. The combined use of the first inner cup 30 and second inner cup 40 focuses on this point.The combined use of the first inner cup 30 and the second inner cup 40 increases the degree of freedom in designing a brassiere to reduce the feeling of pressure and intimidation on the bust and to improve comfort.

[0059] Furthermore, the first inner cup 30 has a first groove 34 and a second groove 35, 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 34 is located at the boundary between the first inner cup side portion 31 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup under-bust portion 32, while the second groove 35 is located at the boundary between the first inner cup under-bust portion 32 on the inside facing the bra cup apex 4 of the first inner cup 30 and the first inner cup's chest-side center portion 33. As shown in FIG. 6 , if a load fluctuation occurs on the first inner cup 30 due to a change in the wearer's posture or other behavior while wearing the brassiere 2, the first inner cup 30 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 30 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 longitudinally inner side facing the bra cup apex 4, making it difficult for the first inner cup 30 to stretch toward the bra cup apex 4. This would make it impossible for the first inner cup 30 to absorb the excessive load. If the first inner cup 30 were made more stretchable by using a material with increased stretchability 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.

[0060] A first groove 34 and a second groove 35 are V-shaped and extend in the shortest direction toward the bra cup's verge line at two locations on the inside longitudinal side of the first inner cup 30 facing the bra cup apex 4, with the first groove 34 located at the boundary between the inside first inner cup side portion 31 facing the bra cup apex 4 of the first inner cup 30 and the first inner cup lower portion 32, while the second groove 35 is located at the boundary between the inside first inner cup lower portion 32 facing the bra cup apex 4 of the first inner cup 30 and the chest side center portion 33 of the first inner cup. The reason why there are two V-shaped grooves at these locations is that, in the first inner cup 30, considering the direction of load in the circumferential direction due to the shape of the bust 1 (breast), the direction (orientation) of load from the bust 1 stretches in the longitudinal direction changes near the boundary between the first inner cup lower portion 32 and the first inner cup side portion 31 and near the boundary between the first inner cup lower portion 32 and the first inner cup chest side center portion 33. In the first inner cup lower part 32, longitudinal stretch G is primarily a stretch in the left-right direction, while stretch F in the first inner cup side parts 32 and stretch K in the first inner cup chest side center part 33 change to a stretch in the longitudinal and vertical directions primarily to match the shape of the bra cup 3. By providing a V-shaped groove at this boundary, the roles of the first inner cup 30 are divided. The first inner cup side parts 31 are stretched primarily in response to load from the sides of the bust (breasts), the first inner cup lower part 32 is stretched primarily in response to load from the lower part of the bust (breasts), and the first inner cup chest side center part 33 is stretched primarily in response to load from the chest side center of the bust (breasts). These stretching actions make the sections divided into three sections by the V-shaped grooves in the first inner cup 30 less susceptible to load fluctuations from adjacent sections, and furthermore, by installing wires 45 at the verge line 5 of the bra cup 3 and using the combined wire method in conjunction with bust correction, the bra cup 3 and first inner cup 30 do not shift from the bust 1, and the structure allows stretching to be concentrated on load fluctuations from the opposing bust 1. This structure allows targeted pressure to support the underside of the bust, the sides of the bust and the center of the chest, achieving ideal bust formation.

[0061] The first inner cup 30 of the present invention is divided into three sections by V-shaped grooves: the first inner cup side section 31, the first inner cup lower section 32, and the first inner cup chest side center section 33. 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.

[0062] As a first option, a groove 36 is provided on the skin side of the first inner cup 30 of Example 1 on the shortest line connecting the groove bottom of the first groove 34 to the verge line 5, and a groove 36 is also provided on the second groove 35 on the shortest line connecting the groove bottom to the verge line 5. As a second option, a long hole 37 is provided near the middle of the shortest line connecting the bottom of the first groove 34 of the first inner cup 30 to the verge line 5, and a long hole 37 is also provided on the second groove 35 on the shortest line connecting the bottom to the verge line 5.

[0063] In the first embodiment, which is the first option, a stripe groove 36 is provided on the skin side of the first inner cup 30 on the shortest line connecting the bottom of the first groove 34 to the verge line 5, and a stripe groove 36 is also provided on the shortest line connecting the bottom of the second groove 35 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 32 stretches due to changes in the shape of the brassiere wearer's bust 1 or bodily behavior, the first inner cup lower part 32 stretches in the direction of the arrow. The diagonal lines indicate the stretched state. At this time, the width of the first groove 34 narrows, and the width of the stripe groove 36 widens, opening diagonally upward and creating a slightly twisted state, which acts to minimize stretching of the adjacent first inner cup side portions 31, minimizing the amount of stretching of the first inner cup side portions 31. Another advantage of providing the stripe groove 36 is that the stripe groove 36 serves as a base point for the first inner cup 30 to bend inward in the circumferential direction to form a rounded shape that conforms to the shape of the bust 1, thereby improving the wearing comfort of the brassiere 2. Furthermore, in Example 3, by using a wire 45 at the verge line 5 in combination with the wire 45, the wire 45 firmly holds the verge line 5 side of the bra cup 3, holding the bust side in place, and the bra cup 3 fitting snugly against the bust 1. The grooves located on the shortest line connecting the bottom of the V-shaped groove of the first inner cup 30 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 45, even if excessive load is placed on the first inner cup 30 from the bust 1 due to changes in body movement, allowing the first inner cup 30 to stretch ideally, and the bust 1 is always supported by stable pressure at the underside, sides and center of the chest, allowing for ideal bust formation.

[0064] In the second embodiment, a slot 37 is provided in the first groove 34 of the first inner cup 30 near the middle of the shortest line connecting the bottom of the first groove 34 to the verge line 5. The second groove 35 also has a slot 37 near the middle of the shortest line connecting the bottom of the first groove 34 to the verge line 5. This will be explained with reference to FIGS. 8 and 9. As shown in FIG. 8, the slot 37 is an elongated, oval-shaped hole. As shown in FIG. 9, assuming that only the first inner cup lower portion 32 stretches due to a change in the shape of the brassiere wearer's bust 1 or bodily movement, the first inner cup lower portion 32 stretches in the direction of the arrow. The diagonal lines indicate the stretched state. At this time, the width of the first groove 34 narrows. The slot 37 widens, opening diagonally upward, minimizing the stretch of the adjacent first inner cup side portion 31. This minimizes the amount of stretch of the first inner cup side portion 31. Furthermore, in Example 3, by using the wire 45 at the verge line 5 in combination with the wire 45, the wire 45 at the verge line 5 located on the periphery of the bra cup 3 causes the verge line 5 side of the bra cup 3 to be firmly held against the bust 1 without slipping, and the bra cup 3 fits snugly against the bust 1. 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 30 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 the bust 1 side by the wire 45, even if excessive load is applied from the bust 1 to the first inner cup 30 due to changes in body movement, so that the first inner cup 30 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.

[0065] The only difference between Example 1 and Example 2 and Example 3 is whether or not wires 45 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 45 attached to the verge line 5, while others expect the wires 45 attached to the verge line 5 to have a stronger hold and a bust-correcting effect such as "pushing" or "lifting" their bust. Bras 2 with wire functions 45 are preferred by those who want the increased support provided by the wires 45 and are concerned about the bra cups 3 slipping away from the bust (breasts) 1 as their body movements change. To accommodate both types of users, the present invention proposes Examples 1 and 2 as appropriate for those who dislike the tightness of the wires 45 attached to the verge line 5 or who dislike the wires 45, while Example 3 is proposed for those who prefer a bra with a bust-shaping or corrective effect provided by the wires 45 attached to the verge line 5.

[0066] The present invention is not limited to brassieres, but may also be applied to clothing having bra cups, such as body suits, bra slips, bra camisoles, and swimwear. [Industrial Applicability]
