Abstract
Description
A soft-support, breathable, multi-cup bra with added volume. Technical Field
[0001] This application belongs to the field of underwear technology, specifically relating to a soft-support breathable expansion bra with multiple cups for increased capacity. Background Technology
[0002] For women with larger breasts, traditional underwire bras offer better support and shape retention. For example, Chinese patent CN210581050U discloses a fabric-covered bra that uses an underwire at the bottom of the molded cup for effective breast support. However, the drawbacks of underwire bras are also obvious. The rigidity of the underwire makes the bra generally stiffer and thicker, and the internal underwire compresses the underbust area during movement, potentially hindering breast development and increasing the risk of breast diseases.
[0003] As people's demands for comfort and health in underwear increase, soft support bras made of materials such as shape memory alloys, nickel-titanium alloys, or soft rubber have gradually appeared on the market to replace underwires. While soft support can reduce the pressure of underwires on the body, it cannot provide better support for women with larger breasts. In addition, a soft support structure made of multiple layers of thick fabric has also appeared on the market to achieve the support function of bras. Although this structure solves the shortcomings of underwires and soft support to some extent, the layering of multiple layers of thick fabric significantly increases the thickness of the center gore and underband areas, which can easily cause a stuffy feeling when wearing, affect breathability, and thus increase skin irritation and discomfort.
[0004] The applicant, with deep expertise in bra technology and extensive communication with users, discovered another problem with current bras: women's bodies are not static; they may experience slight weight gain or loss, or temporary breast enlargement during menstruation. In these situations, previously fitted bras can still be worn, but comfort is reduced, and purchasing new ones is costly. Moreover, during pregnancy or breastfeeding, women's breasts enlarge significantly, making previously fitted bras unwearable and necessitating the purchase of new ones.
[0005] Therefore, there is an urgent need for a soft, breathable bra with multiple cup sizes that can provide extra support and accommodate breast sizes within a certain range. Summary of the Invention
[0006] To address the problems in related technologies, this application proposes a soft-support, breathable, and expandable bra with multiple cup sizes to overcome the aforementioned technical issues in existing technologies. The soft-support structure of this application features triple soft support, maintaining comfort while enhancing support stability. Furthermore, the expandable cups are elastic, achieving an effective expansion effect.
[0007] The technical solution of this application is implemented as follows: a soft-support breathable expansion bra with multiple cups, including a bra body, the bra body including two cups and a band arranged symmetrically on the left and right; wherein, the band is connected to the lower edge of the two cups through a soft support structure to form an underband, and the band is connected to the outer edge of the two cups through the soft support structure to form a side panel.
[0008] The soft support structure includes an inner W-shaped soft support part, an outer W-shaped soft support part, and an expansion sleeve connecting the two W-shaped soft support parts.
[0009] The width of the outer W-shaped soft support is greater than the width of the inner W-shaped soft support. The outer W-shaped soft support partially surrounds the inner W-shaped soft support. The openings of both the outer W-shaped soft support and the inner W-shaped soft support are upward-facing.
[0010] The expansion bandage is a hollow structure woven from multiple elastic materials for breathable expansion.
[0011] It should be noted that in practical applications, the expansion bandage described in this application is usually made of materials such as elastic bands and elastic ropes, which have high elasticity and durability.
[0012] When the inner W-shaped soft support portion serves as the lower circumference supporting the breast, the expansion bandage and the outer W-shaped soft support portion serve as the structure enclosing the chest cavity; when the outer W-shaped soft support portion serves as the lower circumference supporting the breast, the expansion bandage and the inner W-shaped soft support portion serve as the cup structure enclosing the breast.
[0013] It should be noted that bras on the market generally use A, B, C, and D cup sizes to indicate the size of the breasts or chest. The cup size is determined by the difference between the upper bust measurement and the lower bust measurement.
[0014] An A cup means that the difference between the upper bust measurement and the lower bust measurement is approximately 10cm, indicating that the breasts are relatively small.
[0015] A B cup refers to a measurement of approximately 12.5cm between the upper bust and lower bust measurements, representing a medium-sized bra size.
[0016] A C-cup refers to a measurement of approximately 15cm between the upper bust measurement and the lower bust measurement, indicating a relatively large bust.
[0017] A D-cup means that the difference between the upper bust measurement and the lower bust measurement is approximately 17.5cm, indicating a larger bust size.
[0018] Generally, the later the letter in the alphabet, the larger the cup size. When wearing this product, users can use it regardless of whether their breasts are an A cup, a B cup during menstruation, a C cup during pregnancy / breastfeeding, or even a D cup.
[0019] It should be further explained that in actual wear, if the wearer has a small bust (i.e., an A cup or even smaller), the first wearing state can be adopted, where the inner W-shaped soft support acts as the lower band supporting the breast, and the expansion band and outer W-shaped soft support act as the structure wrapping the chest cavity. If the wearer has a large bust (i.e., a C or D cup or even larger), the second wearing state can be adopted, where the outer W-shaped soft support acts as the lower band supporting the breast, and the expansion band and inner W-shaped soft support act as the cup structure wrapping the breast. The expansion band is stretched by the breast, thus achieving the effect of expanding multiple cups with the same bra, and the user does not need to buy a new bra.
[0020] Furthermore, both of the aforementioned W-shaped soft support sections are double-layered structures, while the expansion sleeve is a single-layered structure.
[0021] Furthermore, the inner W-shaped soft support portion includes a first W-shaped edge portion, which is connected to the bra cup;
[0022] The outer W-shaped soft support includes a second W-shaped side, which is connected to the surrounding band.
[0023] The upper edge of the expansion bandage is connected between the first W-shaped edge and the bra cup, and the lower edge of the expansion bandage is connected between the second W-shaped edge and the bandage.
[0024] Furthermore, the upper edge of the expansion bandage is connected between the first W-shaped side and the cup by means of bonding, sewing, or other connection methods; similarly, the lower edge of the expansion bandage is also connected between the second W-shaped side and the bandage by means of bonding, sewing, or other connection methods.
[0025] Furthermore, both cups include an inner surface that fits against the breast skin, and a support piece is provided on the inner surface to lift the breast upward; the lower end of the support piece is connected to the inner W-shaped soft support portion, and the support piece is at least partially suspended in its natural state and does not contact the inner surface of the cup.
[0026] Furthermore, the lower edge of the support piece is connected and fixed to the first W-shaped edge.
[0027] Furthermore, the two cups are integrally compressed molded cups.
[0028] Furthermore, the support piece extends from the lower edge of the left cup to the lower edge of the right cup; the support piece has an upward arc-shaped opening.
[0029] Furthermore, the shroud is provided with a plurality of ventilation holes arranged in a regular or irregular manner.
[0030] Furthermore, the support piece is also provided with multiple ventilation holes arranged in a regular or irregular manner.
[0031] Furthermore, it also includes a shoulder strap, one end of which is connected to the bandage, and the other end extends to connect to the front of the bra body.
[0032] Furthermore, the molded cup has upwardly extending and narrowing attachments on both the left and right sides, which are used for transitional connection with the shoulder strap.
[0033] Furthermore, the bra body includes an inner and outer fabric and a lining fabric that fit together, the outer fabric and the lining fabric are attached along the edges to form two independent cup cavities for placing the cup pads; the lining fabric has an opening that connects to the cup cavity, and one end of the shoulder strap passes through the opening and connects to the cup pad.
[0034] Furthermore, the left and right ends of the band extend in opposite directions to form a back section, and the two back sections are connected by a connector, which includes a buckle.
[0035] The beneficial effects of this application are:
[0036] (1) In this application, the soft support structure cleverly employs an inner W-shaped soft support section and an outer W-shaped soft support section to form all-round support for the underbust and sides of the breast. Combined with the expansion bandage, it forms triple soft support for the chest. This multi-soft support design maintains comfort while enhancing the support stability of the bra body, avoiding the pressure of underwires and rubber rings on the body, and making it more practical.
[0037] (2) Moreover, the expansion band between the two W-shaped soft support parts is made of a hollow structure woven from multiple elastic materials. This design not only maintains the lightness and flexibility of the bra body, but more importantly, it greatly improves breathability and reduces the stuffiness caused by wearing it for a long time, so that the wearer can stay dry and comfortable in various environments.
[0038] (3) Finally, when the wearer has a small bust, the inner W-shaped soft support serves as the lower band supporting the breast, while the expansion band and the outer W-shaped soft support serve as the structure to wrap the chest cavity, providing moderate support; when the wearer has a large bust, the outer W-shaped soft support serves as the lower band supporting the breast, while the expansion band and the inner W-shaped soft support serve as the cup structure to wrap the breast, and the expansion band is stretched by the breast so that the same bra can achieve the effect of expanding multiple cups, avoiding the pressure or discomfort caused by the fixed size of traditional bras on the enlarged breasts, and ensuring that women of all body types can enjoy a tailor-made wearing experience.

Therefore, they should not be construed as limitations on this application.
[0046] Example 1
[0047] As shown in Figures 1-2, this embodiment provides a soft-support breathable expansion bra with multiple cups, including a bra body 1. The bra body 1 includes two cups 11 arranged symmetrically on the left and right and a band 12. The band 12 is connected to the lower edge of the two cups 11 through a soft support structure 2 to form an underband 121. The band 12 is connected to the outer edge of the two cups 11 through the soft support structure 2 to form a side panel 122.
[0048] The soft support structure 2 includes an inner W-shaped soft support part 21, an outer W-shaped soft support part 23, and an expansion band 22 connecting the two W-shaped soft support parts;
[0049] The width of the outer W-shaped soft support 23 is greater than the width of the inner W-shaped soft support 21. The outer W-shaped soft support 23 partially surrounds the inner W-shaped soft support 21. The openings of both the outer W-shaped soft support 23 and the inner W-shaped soft support 21 are upward.
[0050] The expansion cloth 22 is a hollow structure woven from multiple elastic materials for breathable expansion.
[0051] It should be noted that in practical applications, the expansion bandage 22 described in this application is usually made of elastic bands, elastic ropes and other materials, which have high elasticity and durability, and will not affect the expansion effect of the bra body 1 even after multiple washes.
[0052] When the inner W-shaped soft support part 21 is used as the lower circumference supporting the breast, the expansion bandage 22 and the outer W-shaped soft support part 23 serve as the structure that wraps around the chest cavity; when the outer W-shaped soft support part 23 is used as the lower circumference supporting the breast, the expansion bandage 22 and the inner W-shaped soft support part 21 serve as the cup structure that wraps around the breast.
[0053] It should be noted that bras on the market generally use A, B, C, and D cup sizes to indicate the size of the breasts or chest. The cup size is determined by the difference between the upper bust measurement and the lower bust measurement.
[0054] An A cup means that the difference between the upper bust measurement and the lower bust measurement is approximately 10cm, indicating that the breasts are relatively small.
[0055] A B cup refers to a measurement of approximately 12.5cm between the upper bust and lower bust measurements, representing a medium-sized bra size.
[0056] A C-cup refers to a measurement of approximately 15cm between the upper bust measurement and the lower bust measurement, indicating a relatively large bust.
[0057] A D-cup means that the difference between the upper bust measurement and the lower bust measurement is approximately 17.5cm, indicating a larger bust size.
[0058] Generally, the later the letter in the alphabet, the larger the cup size. When wearing the soft-support breathable expansion bra in this embodiment, users can use it regardless of whether their breasts are A cup, B cup during menstruation, C cup during pregnancy / breastfeeding, or even D cup.
[0059] It should be further explained that in actual wear, if the wearer has a small bust (i.e., an A cup or even smaller), the first wearing state can be adopted, in which the inner W-shaped soft support 21 acts as the lower band supporting the breast, and the expansion band 22 and the outer W-shaped soft support 23 act as the structure wrapping the chest cavity. If the wearer has a large bust (i.e., a C or D cup or even larger), the second wearing state can be adopted, in which the outer W-shaped soft support 23 acts as the lower band supporting the breast, and the expansion band 22 and the inner W-shaped soft support 21 act as the cup structure wrapping the breast, and the expansion band 22 is stretched by the breast, thus achieving the effect of expanding multiple cups with the same bra, and the user does not need to buy a new bra.
[0060] Firstly, in this embodiment, the soft support structure 2 cleverly employs an inner W-shaped soft support portion 21 and an outer W-shaped soft support portion 23 to form all-around support for the underbust and sides of the breast. Combined with the expansion bandage 22, this creates triple soft support for the chest. This multi-layered soft support design maintains comfort while enhancing the support stability of the bra body 1, avoiding the pressure of underwires and rubber rings on the body, thus improving practicality.
[0061] Moreover, the expansion band 22 located between the two W-shaped soft support sections adopts a hollow structure woven from multiple elastic bands. This design not only maintains the lightness and flexibility of the bra body 1, but more importantly, it greatly improves breathability and reduces the stuffiness caused by wearing it for a long time, so that the wearer can stay dry and comfortable in various environments.
[0062] Finally, for wearers with small breasts, the inner W-shaped soft support 21 serves as the lower band supporting the breasts, while the expansion band 22 and the outer W-shaped soft support 23 act as a structure enclosing the chest cavity, providing moderate support. For wearers with large breasts, the outer W-shaped soft support 23 serves as the lower band supporting the breasts, while the expansion band 22 and the inner W-shaped soft support 21 act as a cup structure enclosing the breasts. The expansion band 22 is stretched by the breasts to achieve an effective expansion effect, avoiding the pressure or discomfort that traditional bras may cause due to improper sizing, ensuring that women of all body types can enjoy a tailor-made wearing experience.
[0063] Specifically, both of the W-shaped soft support sections are double-layered structures, while the expansion sleeve 22 is a single-layered structure, in order to further improve the air permeability of the soft support structure 2.
[0064] Specifically, the inner W-shaped soft support portion 21 includes a first W-shaped edge portion 3, which is connected to the bra cup 11.
[0065] The outer W-shaped soft support portion 23 includes a second W-shaped side portion 4, which is connected to the surrounding band 12.
[0066] The upper edge of the expansion bandage 22 is connected between the first W-shaped side 3 and the bra cup 11, and the lower edge of the expansion bandage 22 is connected between the second W-shaped side 4 and the bandage 12.
[0067] More specifically, the upper edge of the expansion bandage 22 is connected between the first W-shaped side 3 and the cup 11 by means of bonding, sewing or other connection; similarly, the lower edge of the expansion bandage 22 is also connected between the second W-shaped side 4 and the bandage 12 by means of bonding, sewing or other connection; thereby better fixing the upper and lower ends of the expansion bandage 22.
[0068] Specifically, it also includes a shoulder strap 6, one end of which is connected to the band 12, and the other end extends to connect to the front of the bra body 1.
[0069] Specifically, the two cups 11 are integrally compressed molded cups.
[0070] More specifically, the molded cup has an upwardly extending and narrowing attachment 7 on both the left and right sides, the attachment 7 being used for transitional connection with the shoulder strap 6.
[0071] It should be noted that the attached 7 is integrated with the molded cup. By directly connecting the shoulder strap 6 to the attached 7 of the molded cup, the shoulder strap 6 can better distribute the weight of the breast. When adjusting the shoulder strap 6, the user can directly pull the molded cup, thereby achieving a more direct lift for the breast.
[0072] Specifically, the two cups 11 include an inner side that fits against the skin of the breast, and a support piece 5 is provided on the inner side to lift the breast upward; the lower end of the support piece 5 is connected to the inner W-shaped soft support part 21, and the support piece 5 is at least partially suspended in its natural state and does not contact the inner side of the cup 11.
[0073] More specifically, the lower edge of the support piece 5 is connected and fixed to the first W-shaped edge 3.
[0074] Specifically, the support piece 5 extends from the lower edge of the left cup 11 to the lower edge of the right cup 11; the support piece 5 has an upward arc-shaped opening.
[0075] The support piece 5 effectively lifts the breasts from the inside of the cup 11, while the soft support structure 2 lifts the breasts from the outside of the cup 11. The two work together to achieve a synergistic effect of lifting the breasts.
[0076] Specifically, the shroud 12 is provided with a plurality of ventilation holes arranged in a regular or irregular manner.
[0077] More specifically, the support piece 5 is also provided with a plurality of ventilation holes arranged in a regular or irregular manner.
[0078] The design of the ventilation holes further improves the breathability and comfort of the bra body 1.
[0079] Specifically, the left and right ends of the band 12 extend in opposite directions to form a back section, and the two back sections are connected by a connector, which includes a buckle.
[0080] Example 2
[0081] As shown in Figures 3-4, this embodiment provides another type of soft-support breathable bra with multiple cups for increased volume. Features not explained in this embodiment can be explained using the methods described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:
[0082] The bra body 1 includes an outer fabric 8 and a lining fabric 9 that are attached to each other. The outer fabric 8 and the lining fabric 9 are attached along the edges to form two independent cup cavities for placing the cup pads. The lining fabric 9 has an opening that connects to the cup cavity, and one end of the shoulder strap 6 passes through the opening and connects to the cup pad.
[0083] It should be noted that in this embodiment 2, the two cups 11 are not integrally compressed molded cups, but are formed by inserting two separate cup pads into the cup cavity between the outer fabric 8 and the inner fabric 9. The two cup pads are not fixed, but the cup cavity also limits the range of movement of the cup pads to prevent the cup pads from coming out of the insertion port. When wearing the bra, the user can also slightly adjust the position of the cup pads according to their own needs, so that the bra body 1 fits the user's chest better.
[0084] Furthermore, by directly connecting the shoulder straps 6 to the cup pads, the shoulder straps 6 can better distribute the weight of the breasts. When adjusting the shoulder straps 6, the user can directly pull the cup pads, thus achieving a more direct lift to the breasts. This design not only enhances the support of the bra body 1 for the breasts but also allows the wearer to easily adjust the tightness of the shoulder straps 6 according to individual needs and comfort, thereby achieving the ideal wearing effect. Compared to designs that connect the shoulder straps 6 to the outer fabric 8 or the lining fabric 9, the direct connection to the cup pads can more effectively lift the breasts, creating a more upright and confident bust line.
[0085] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this application should also fall within the protection scope of the claims of this application. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
