Description

An adjustable, seamless bra with integrated cup and underwire design. Technical Field

[0001] This application belongs to the field of underwear technology, specifically relating to an adjustable front-fastening seamless underwear with integrated molded cups and underwire. Background Technology

[0002] A front-closure bra is a uniquely designed bra where the clasp is located at the front of the chest rather than the back, typically at the center gore. This design not only makes it easier to put on and take off but also provides better support and lift, making it especially suitable for people with limited back mobility or poor hand dexterity. The front-closure bra offers significant convenience.

[0003] Front-closure bras typically use hooks, snaps, or zippers for fastening, and come in various styles, including full-cup and half-cup bras, to suit different breast shapes and needs. For example, Chinese patent CN208909144U discloses a front-closure bra that makes large breasts appear smaller, and it also mentions that a front clasp is located between the center gore on both sides of the front-closure bra.

[0004] However, existing front-fastening bras have also revealed some drawbacks in actual use.

[0005] First, the main problem lies in the sewing process of the front clasp. Most front-closure bras use a sewing technique to attach the front clasp to the inside of the cups or the center gore area of ​​the underband. While this method is secure, the seams can easily rub against the skin during daily wear. Prolonged friction can lead to redness, itching, and even allergic reactions, causing discomfort. Some front-closure bras also have the cups and underband sewn together; these extra seams further increase the chance of friction against the skin, exacerbating the risk of allergies.

[0006] Secondly, the design of the front clasp also has issues. Since the front clasp typically uses a single clasp design and the fastening distance is not adjustable, this is undoubtedly a challenge for users with wider underbust bands. When fastening the front clasp, they may feel significant pressure, even resulting in indentations. This discomfort not only affects wearing comfort but may also negatively impact blood circulation in the chest, reducing the overall user experience. For users with narrower underbust bands, it is prone to loosening during use.

[0007] Therefore, there is an urgent need for an adjustable, seamless front-fastening bra with integrated molded cups and underwire. Summary of the Invention

[0008] To address the problems in related technologies, this application proposes an adjustable front-fastening, seamless bra with integrated molded cups and underband, overcoming the aforementioned technical issues in existing technologies. By adopting an integrated molded cup and underband design, this application avoids direct friction between the seams and the skin, as is common in traditional sewing processes, thus improving wearing comfort. Furthermore, the extension effectively increases the lateral adjustment distance of the underbands on both sides, allowing users to better grasp the front fasteners for easier fastening, making it more convenient to wear.

[0009] The technical solution of this application is implemented as follows: an adjustable front-fastening seamless bra with integrated molded cups and underband, including a bra body, the bra body including two cups at the front, and a back band connecting the outer sides of the two cups as one piece, the inner sides of the two cups that are close to each other are connected by a front fastener.

[0010] Each of the bra cups includes an upper molded cup and a lower band distributed in an upward and downward direction; the inner sides of the two lower bands that are close to each other extend towards each other to form an extension; the front fastener is fixed at a position close to the two extensions; the two extensions are connected to form a gore.

[0011] The lower strip includes a surface layer, which is integrally formed with the upper mold cup.

[0012] Furthermore, each of the upper mold cups has an air bladder strip in the interlayer at the bottom.

[0013] Furthermore, the front fastener includes a hook and a hooked portion that engage with each other; the hook and the hooked portion are respectively connected to extensions on different sides;

[0014] The outer edge of the extension extends beyond the inner edge of the upper mold cup;

[0015] The underlayer also includes an inner layer for contact with the skin, which is bonded to the outer layer.

[0016] Furthermore, the hooked portion includes a hook ring and a first limiting portion, one side of the hook ring extends to connect with the first limiting portion; wherein the outer layer of the undercut on one side has a first opening at the position of the extension portion for the hook ring to pass through, and the first limiting portion is embedded between the inner layer and the outer layer.

[0017] Furthermore, the hook includes a hook head and a second limiting part. One side of the hook head extends to connect with the second limiting part. On the other side, the surface of the undercut has a second opening at the position of the extension part for the hook head to pass through. The hook head is used to fasten with the hook ring. The second limiting part is embedded between the inner layer and the outer layer.

[0018] Furthermore, the first limiting part is embedded between the inner layer and the outer layer by adhesive; the other end of the hook is also embedded between the inner layer and the outer layer by adhesive.

[0019] Furthermore, the two ends of the back band are respectively connected to the outer edges of the two cups to form a side panel that wraps around the accessory breast; the back band includes an inner and outer skin-contact layer and a fabric layer; the cup includes an outer cup surface and an inner cup surface, the inner cup surface being used to contact the breast skin;

[0020] Each of the side panels is respectively attached to the side edge of the inner cup surface of the corresponding cup, forming an inner arc transition line on the inner cup surface, and an outer arc transition line on the fabric layer.

[0021] Furthermore, each of the aforementioned arc-shaped transition lines extends from the upper edge of the upper molded cup to the lower edge of the underwire; when worn, both the inner and outer arc-shaped transition lines cover the side edges of the breast.

[0022] Furthermore, the front fastener may be a multi-row buckle or a retractable buckle.

[0023] Furthermore, in this application, when the front fastener is a multi-row fastener, the hooked portion has at least two rows.

[0024] It should be noted that the front fastener can also be a single-row buckle or a single buckle, but the fastening distance of a single-row buckle or a single buckle is not adjustable, unlike multi-row buckles or telescopic buckles which are more convenient to use. Users can choose according to their actual situation.

[0025] Furthermore, the lower edge of each of the upper mold cups is connected to the upper edge of the corresponding lower mold, and an arc-shaped transition section is provided at the junction of the inner side of the upper mold cup and the upper edge of the extension.

[0026] Furthermore, the lower edge of each of the lower plates is butterfly-shaped, and after the front fastener is connected, the center portion forms an upwardly convex curve.

[0027] The beneficial effects of this application are:

[0028] (1) This application adopts an integrated design of the molded cup underband, making the surface of the underband and the upper molded cup a single molded structure, thus avoiding direct friction between the seams and the skin in traditional sewing processes. This design reduces the contact points between the underwear and the skin of the chest during wear, thereby reducing problems such as skin redness and itching caused by friction. At the same time, the integrated structure of the molded cup underband also helps to provide better support and fit, further improving the comfort and stability of wearing.

[0029] (2) Secondly, by reducing the use of sewing threads, especially avoiding direct contact between sewing threads and sensitive areas such as the center of the breast, this underwear greatly reduces the risk of allergic reactions caused by sewing threads.

[0030] (3) Furthermore, traditional fasteners are sewn directly to the inner side of the bra cup, while the front fastener in this application is cleverly positioned on the extension formed by the two underbands extending towards each other. This extension effectively lengthens the lateral adjustment distance of the two underbands, allowing the bra to better adapt to different body shapes and wearing needs, providing a more comfortable and snug fit. The design of the extension also makes it easier for the user to grasp the front fastener for fastening, making wearing the bra more convenient. Attached Figure Description

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0042] As shown in Figures 1-4, this embodiment provides an adjustable front-fastening seamless bra with integrated molded cups and underband, including a bra body. The bra body includes two cups 1 located at the front and a back band 2 that connects the outer sides of the two cups 1 together. The inner sides of the two cups 1 that are close to each other are connected by a front fastener 3.

[0043] Each of the bra cups 1 includes an upper molded cup 11 and a lower band 12 distributed in an upper and lower position; the inner sides of the two lower bands 12 extend towards each other to form an extension 13; the front fastener 3 is fixed at a position close to the two extensions 13; the two extensions 13 are connected to form a center gore 6.

[0044] The lower mold 12 includes a surface layer 121, which is integrally formed with the upper mold cup 11.

[0045] Firstly, this embodiment employs an integrated design for the molded cup underband, making the surface layer 121 of the underband 12 and the upper molded cup 11 a single molded structure, thus avoiding direct friction between the seams and the skin, a problem common in traditional sewing processes. This design significantly reduces the contact points between the bra and the chest skin during wear, thereby reducing issues such as redness and itching caused by friction. Simultaneously, the integrated structure of the molded cup underband 12 also helps provide better support and fit, further enhancing wearing comfort and stability.

[0046] Secondly, by reducing the use of stitches, especially avoiding direct contact between stitches and sensitive areas such as the center gore, this bra significantly reduces the risk of allergic reactions caused by stitches. This is a significant improvement for wearers with sensitive or allergy-prone skin. At the same time, the seamless design makes the bra smoother overall, reducing the feeling of a foreign object when wearing it.

[0047] Furthermore, traditional fasteners are sewn directly to the inner side of the cup 1, which limits the flexibility of the bra during wear. In this embodiment, however, the front fastener 3 is cleverly positioned on the extension 13 formed by the two underbands 12 extending towards each other from their inner sides. The extension 13 effectively extends the lateral adjustment distance of the two underbands 12, allowing the bra to better adapt to different body shapes and wearing needs, providing a more comfortable and snug fit. Through this structural adjustment, the bra maintains its aesthetically pleasing seamless design while significantly enhancing its flexibility and adaptability. The design of the extension 13 also makes it easier for the user to grasp the front fastener 3 for fastening, making it more convenient to wear.

[0048] Specifically, each of the upper mold cups 11 has an airbag strip 111 in the interlayer at the bottom.

[0049] In this embodiment, an airbag strip 111 is used instead of a traditional steel ring to fix and support the upper molded cup 11, so that the upper molded cup 11 neither rides up nor slides down, further improving the gathering effect on the breasts.

[0050] Specifically, the outer side of the extension 13 extends beyond the inner side of the upper mold cup 11.

[0051] The underlayer 12 also includes an inner layer 122 for contact with the skin, the inner layer 122 being attached to and connected to the outer layer 121.

[0052] Specifically, the front fastener 3 includes a hook 31 and a hooked part 32 that engage with each other; the hook 31 and the hooked part 32 are respectively connected to the extension part 13 on different sides.

[0053] More specifically, the hooked portion 32 includes a hook loop 321 and a first limiting portion 322. One side of the hook loop 321 extends to connect with the first limiting portion 322. The surface layer 121 of one side of the undercut 12 has a first opening 1211 at the position of the extension portion 13 for the hook loop 321 to pass through. The first limiting portion 322 is embedded between the inner layer 122 and the surface layer 121.

[0054] As shown in Figures 5-6, the hook 31 includes a hook head and a second limiting part. One side of the hook head extends to connect with the second limiting part. On the other side, the surface layer 121 of the lower lip 12 has a second opening at the position of the extension 13 for the hook head to pass through. The hook head is used to fasten with the hook ring 321. The second limiting part is embedded between the inner layer 122 and the surface layer 121.

[0055] More specifically, the first limiting part 322 is embedded between the inner layer 122 and the outer layer 121 by means of adhesive; the other end of the hook 31 is also embedded between the inner layer 122 and the outer layer 121 by means of adhesive.

[0056] It should be noted that in this embodiment, the hook 31 and the hooked part 32 are preferably connected to the lower stripe 12 by adhesive bonding. Compared with the traditional sewing method, bonding can reduce the number of sutures, thereby avoiding friction between the sutures and human skin. Moreover, the first limiting part 322, the hook 31, etc. are embedded between the inner layer 122 and the outer layer 121, making the hook 31 and the hooked part 32 more invisible and aesthetically pleasing.

[0057] As shown in Figure 2, the two ends of the back band 2 are respectively connected to the outer sides of the two cups 1 to form a side panel 23 that wraps around the accessory breast; the back band 2 includes an inner and outer skin-adhering layer 22 and a surface fabric layer 21; the cup 1 includes an outer cup surface and an inner cup surface, the inner cup surface being used to contact the breast skin.

[0058] Each of the side panels 23 is respectively attached to the side edge of the inner cup surface of the corresponding cup 1, and forms an inner arc transition line 4 on the inner cup surface, while forming an outer arc transition line 5 on the fabric layer 21.

[0059] Specifically, each of the arc-shaped transition lines extends from the upper edge of the upper molded cup 11 to the lower edge of the lower band 12; when worn, both the inner and outer arc-shaped transition lines cover the side edges of the breast.

[0060] The inner and outer curved transition lines significantly shorten the horizontal width of the traditional cup. At the same time, the side panel 23, which is thinner than the cup 1, is used to wrap the accessory breast. This can tighten the accessory breast and avoid excessive pressure on it, thereby reducing friction on the underarm skin and further improving the comfort of wearing it.

[0061] Specifically, the front fastener 3 includes multiple rows of buckles or retractable buckles.

[0062] More specifically, in this embodiment, when the front fastener 3 is a multi-row fastener, the hooked portion 32 has at least two rows;

[0063] It should be noted that the front fastener 3 can also be a single-row buckle or a single buckle, but the fastening distance of a single-row buckle or a single buckle is not adjustable, unlike multi-row buckles or telescopic buckles which are more convenient to use. Users can choose according to their actual situation.

[0064] It should be further noted that this embodiment does not limit the type of the front fastener 3, and all types of fasteners that can adjust the length of the lower band 12 have the same technical effect; nor does it limit the specific number of rows of fasteners, multiple rows have the same technical effect.

[0065] As shown in Figures 1-2, the lower edge of each upper mold cup 11 is connected to the upper edge of the corresponding lower chuck 12, and an arc-shaped section 7 is provided at the junction of the inner side of the upper mold cup 11 and the upper edge of the extension 13.

[0066] The design of the arc-shaped transition segment 7 allows for a smoother transition of the bra at key areas (such as the junction of the upper cup 11 and the extension 13), achieving a balance of forces and reducing the possibility of stress concentration. This design helps to disperse the tension or pressure that the bra may experience during wear, reducing the risk of tearing due to stress concentration.

[0067] As shown in Figures 7-8, the lower edges of each of the underbands 12 are butterfly-shaped, conforming to ergonomics and avoiding the stomach area to prevent pressure on the stomach. After the front fasteners 3 are connected, the center section 6 forms an upward-convex curve to fit the lower edge of the human chest. The rear band 2 is designed in an arch shape to improve stability and prevent displacement or slippage during adaptation.

[0068] 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.
