[0024] In the claims, the description and the above drawings of the utility model, such as the terms“include”,“have” and their variants, are intended to“include but not limited to”.

[0025] The utility model relates to a kind of anti-bulge cup pad, it includes several arc pieces 11, each arc piece 11 has center point 111 and first radius line and second radius line, and the center point 111 of each arc piece 11 is coincidently arranged, first radius line and second radius line are respectively coincidently connected with the radius line of adjacent arc piece 11 to form the nearly circular cup pad body 1, the arc length side of each arc piece 11 is outwardly protruding to form the flange portion 112 of body 1, and the connecting point of adjacent arc piece 11 forms the inner recess 113 of body 1, the flange portion 112 and inner recess 113 surround the outer periphery of body 1 and appear alternately, the thickness of flange portion 112 and inner recess 113 is equal.

[0026] The arc-shaped pieces 11 can be equal in size, or the arc-shaped pieces 11 can be unequal in size, in which case the first radius line of the adjacent arc-shaped pieces 11 is equal to the second radius line, that is, the radius lines of the arc-shaped pieces 11 are equal, and correspondingly, the shape surrounded by the arc-shaped pieces 11 is irregular petal-shaped, or the first radius line of the arc-shaped pieces 11 is not equal to the second radius line, as long as the adjacent arc-shaped pieces 11 can be connected to surround a circular shape, an elliptical shape or a polygonal shape, and the relative length of the first radius line and the second radius line of the arc-shaped piece is not limited in the utility model, and is applicable to the protection scope of the utility model.

[0027] Secondly, the number of the arc-shaped pieces 11 can be three, four, five or more, as long as the cup pad surrounded by the arc-shaped pieces 11 can ensure to shield the areola and the nipple point, and the concave and the flange are formed at the arc line connection of the arc-shaped pieces 11, which is beneficial to the ventilation of the cup pad, preferably, the number of the arc-shaped pieces 11 of the utility model is five, the equal arc-shaped pieces 11, and the thickness of the arc-shaped pieces 11 is increased or reduced in proportion, so that when the center point 111 of the cup pad corresponds to the BP point of the chest, the five flanges of the cup pad can shield the areola, so that the effect of shielding the areola and the nipple point can be achieved with the least material. Since the cup pad is attached to the chest, and it is easy to sweat when the chest is in the lower part, at this time, the concave part 113 and the flange part 112 appear alternately, the concave part 113 is a hollow structure relative to the flange part 112, and correspondingly, the concave part 113 can improve the ventilation of the bra problem, can avoid sweating, and improves the aesthetic degree of the cup pad.

[0028] In addition, the cup pad body 1 is provided as a three-layer cloth structure, including two layers of Jiaji cloth and one layer of sponge material, that is, the two layers of Jiaji cloth sandwich the layer of sponge material, so that the cup pad body 1 has good ventilation.

[0029] On this basis, the thickness of the cup mat at different positions can be equal or unequal, in the embodiment, the thickness of the cup mat body 1 is variable, for example, the thickness of the center point 111 of the cup mat is the largest, which can better shield the nipple, the thickness of the edge of the cup mat is the smallest, that is, the thickness gradually decreases from the center point 111 of the cup mat to the edge, the thickness of the center point 111 of the cup mat is about 3mm, the thickness of the edge of the cup mat is 1mm, further, the thickness of the flange position and the concave position of the cup mat is 1mm, and the cup mat has a certain height difference from the center to the edge, the height difference is 1.5-1.8mm, and the thickness gradually decreases from the center to the edge, so that there is no obvious gradient between the edge and the center point 111 of the cup mat from the outside, and the cup mat is in smooth contact with the chest during wearing, avoiding the uncomfortable friction of the uneven position of the inner surface of the cup mat with the chest, thereby improving the comfort of the cup mat.

[0030] In another embodiment of the utility model, the cup mat is applied in a bra, at this time the bra further comprises a cup 2, a bottom 3, a hook 7 and a shoulder strap 5, the cup mat and the cup 2, the bottom 3, the hook 7 and the shoulder strap 5 form the bra, the inner layer sheet 22 is provided with a first saving way 221 and a second saving way 222, the first saving way 221 and the second saving way 222 are arranged in a radial manner, one end of the first saving way 221 is coincident with and fixedly connected to the center point 111 of the cup mat, and the first saving way 221 extends outward along the radial direction of the inner layer sheet 22, the other end point of the first saving way 221 is fixedly connected to the edge of the inner layer sheet 22, the second saving way 222 is in an eight-character shape with the first saving way 221, and one end of the second saving way 222 extends to the edge of the inner layer sheet 22, the first saving way 221 and the second saving way 222 cooperatively form an arc surface structure of the inner layer sheet, and the arc surface structure covers the cup mat, and the highest point of the arc surface structure is coincident with the center point 111 of the cup mat and the end point of the first saving way 221.

[0031] In the utility model, the bottom 3 is integrally formed as a whole, comprising a lower part 32, a back part 31 and a side part 33, wherein the lower part 32 is arranged at the middle of the whole, the back part 31 and the side part 33 are both two and symmetrically distributed relative to the lower part 32, the side of the side part 33 is connected to the side of the lower part 32, the other side of the side part 33 is connected to the side of the back part 31, after being connected, the bottom of the lower part 32 and the bottom of the back part 31 and the side part 33 form a smooth curve, avoiding the friction of the bra with the chest due to the up-and-down movement of the chest during movement, and reducing the use experience.

[0032] Further, in order to improve the air permeability of the bra, the lower part 32, the back part 31 and the side part 33 are all made of light and thin and air-permeable materials such as lace and netting with air holes, avoiding the sweating of the lower cup bowl position of the cup mat.

[0033] It should be noted that the center point 111 of the pad is fixed to the endpoint of the inner layer 22 of the first channel 221, and this endpoint is at the highest point of the inner layer 22. The highest point of the inner layer 22 is positioned opposite to the 2BP point of the bra cup, allowing the pad to fit more accurately on the nipple and preventing the nipple and areola from being exposed. At this time, this endpoint is the tip 2211 of the first channel 221. During use, the center point 111 of the pad is fixed to the tip 2211 of the first channel 221. After fixing, the edge of the pad can swing slightly around the center of the pad to prevent it from shifting and to avoid leakage during movement. In this embodiment, the pad is shaped with five flanges 112, and the five flanges 112 form the shape of peach petals, improving the aesthetics of the pad.

[0034] In this embodiment, the size of the cup pad can be further limited by restricting the cup height. The highest point of the cup pad is the length measured directly from the highest point of the semi-circular cup edge to the connection point of the two semi-circular cup edges. Preferably, the cup height is 7cm-9cm. This length conforms to the human body structure and can cover the nipple and areola. If it is lower than this size range, the cup pad cannot cover the nipple and areola well. If it is higher than this size range, the cup pad has too large a coverage area and is prone to causing sweating when worn.

[0035] Furthermore, to further prevent cup slippage, the inner lining can be designed with a double-layered yarn structure, folded into a net shape. The top of the net shape is closed, while the bottom is open and sewn to the lower cup bowl. The net shape has an inner and outer layer of yarn, with the inner layer fitting snugly against the skin. Both the inner and outer layers of the net shape have darts 221 and 222, with darts 221 and 222 overlapping and aligned, forming two overlapping arc-shaped surfaces. The upper edge of the coaster is precisely located at the overlapping position of the net shape. The center point 111 of the coaster is fixedly connected to the tip 2211 of dart 221 on the inner layer of yarn. During use, the sides and bottom of the net shape are fixed, limiting the coaster's movement and improving its usability.

[0036] Furthermore, Provincial Highway 1 221 connects to one of the adjacent flanges, while Provincial Highway 2 222 is distributed in a V-shape with Provincial Highway 1 221. One end of Provincial Highway 2 222 is fixed to the lower edge of the inner layer 22. This allows Provincial Highways 1 221 and 222 to adapt the shape of the cup pad to the shape of the inner layer 22, enabling the bra cup 2 to better conform to the shape of the breast, reducing pressure on the breast, and improving comfort and shaping effect. Moreover, Provincial Highway 1 221 passes through the center line of the concave portion 113, limiting the cup pad's swing amplitude under pressure, further improving the stability of the cup pad.

[0037] The cup pad is fixed on the inner layer yarn, and further, the fixing process can be fixed by sewing or by adhesion, in the utility model, the center point 111 of the cup pad is fixed by a single needle at the slotted tip 2211 of the slotted portion one 221 of the inner layer yarn, the fixed length is less than 1 cm, the mesh bag-shaped material can increase the air permeability of the cup pad and prevent the position of the cup bowl from sweating, in addition, since the upper edge of the double-layer yarn structure is not fixed, the edge of the cup pad is not limited by the height of the cup pad after the lower end of the cup pad and the bowl are fixed, therefore, the cup pad body 1 can slightly swing along the edge of the cup pad with the highest point as the axis center, the highest point of the cup pad can be slightly moved in the inner layer yarn after being fixed, and the cup pad can be slightly adjusted according to the actual situation after being worn, the cup can be prevented from running during the movement, and the utility model is suitable for people with different chest sizes.

[0038] The cup 2 further comprises a surface layer sheet 21, the surface layer sheet 21 is arranged in a superposition manner with the inner layer sheet 22, and the surface layer sheet 21 is provided with a slotted portion three 211 and a slotted portion four 212, the slotted portion three 211 is arranged in a coincident manner with the slotted portion one 221, the slotted portion four 212 is arranged in an alignment manner with the slotted portion two 222 and is connected, and the slotted portion three 211 and the slotted portion four 212 cooperate to form an arc-shaped structure 114 capable of being formed with the inner layer sheet 22.

[0039] In the embodiment, the surface area of the surface layer sheet 21 is greater than the surface area of the inner layer sheet 22 after being folded, and the surface layer sheet 21 protrudes from the upper edge of the double-layer yarn structure at the cup bowl position, at this time, the upper edge of the surface layer sheet 21 is fixedly connected with the shoulder strap 5 at the cup bowl position of the cup 2, at this time, the protruding part of the surface layer sheet 21 from the inner layer sheet 22 can further increase the supporting effect on the chest, and the surface layer sheet 21 is mostly provided with a lace pattern to form a shielding structure covering the upper part of the breast.

[0040] In order to further improve the supporting effect of the bra body 1 on the chest, a steel support 4 is installed at the bottom edge of the inner layer sheet 22, the steel support 4 is fixedly connected with the edge of the inner layer sheet, the steel support 4 is made of soft steel, which improves the comfort of the cup pad, and one of the flange portions 112 of the peach-shaped cup pad faces the lowest point of the steel support 4 on the bra body 1, at this time, the flange portion 112 can cover the lower edge of the chest, and a pattern is arranged at the position corresponding to the concave portion 113 of the surface layer sheet 21, which can avoid the lower part of the bra from being exposed, and reduce the experience of the user.

[0041] The bifurcated strips 51 are arranged at the connection of the shoulder straps 5 and the cups 2, two bifurcated strips 51 are arranged with equal width, one end of the bifurcated strips 51 is connected with the shoulder straps 5, the other end of the bifurcated strips 51 is fixedly connected with the upper edge of the cups 2, and the distance between the two bifurcated strips 51 gradually decreases along the length direction of the bifurcated strips 51, and the two bifurcated strips 51 are arranged at the connection of the shoulder straps 5. That is, the contact width of the bifurcated strips 51 with the surface sheet 21 and the inner sheet 22 of the cups 2 is greater than the contact width with the shoulder straps 5, that is, the two bifurcated strips 51 are arranged with equal width, and the resultant force of the two bifurcated strips 51 converges to the shoulder straps 5, so that the shoulder straps 5 have better supporting effect on the bra body 1.

[0042] One end of the shoulder straps 5 is connected with the upper end of the cups 2, and the other end is connected with the two ends of the lower straps 32. The hook 7 is arranged at the tail end of the back strap 31, and the hook 7 is connected with the shoulder straps 5 and the upper edge of the back strap 31 to form a "U" shape. The two ends of the U-shaped structure can provide an oblique upward pulling force to the back strap 31, the force point in this direction is at the hooking position of the hook 7, and the pulling force of the shoulder straps 5 is decomposed into vertical and horizontal directions, so that the force pulling the back strap 31 upward is reduced. In the process of movement, the U-shaped structure can also increase the stability of the back of the body, and improve the shaping effect of the bra on the chest. In addition, the adjusting buckle is arranged on the shoulder straps 5, the length of the shoulder straps 5 can be adjusted, and it can be applied to different people. The length of the shoulder straps 5 can be adjusted according to actual needs, so as to avoid that the shoulder straps 5 are too short to press the chest.

[0043] In order to improve the stability of the bra during wearing, the double-row glue bones 6 are arranged at the connection between the side straps 33 and the back strap 31, and the double-row glue bones 6 are arranged on the side close to the skin.
