Description

[Technical Field]

[0001] This utility model relates to the field of underwear, specifically to a supportive underwear. [Background Technology]

[0002] Traditional bras typically use underwires in the underband area to provide support for the breasts. However, the rigidity of underwires can compress the breasts and ribs with prolonged wear, restricting blood circulation. Furthermore, their rigidity cannot adapt to the dynamic deformation of the breasts during movement, resulting in poor comfort. In recent years, soft support strips have gradually replaced underwires in the market. These strips use soft, elastic materials to reduce pressure on the breasts while retaining support, becoming a mainstream trend.

[0003] However, existing soft support structures still have the following drawbacks: friction between the soft support strip and the outer layer. The soft support strip is usually directly fixed to the outer fabric of the underwear, which causes it to rub against the outer clothing frequently. This makes the outer fabric of the underwear prone to wear and tear, pilling, and the soft support strip prone to delamination, thus accelerating the wear and tear of the underwear. In addition, when wearing outer clothing close to the skin, the outline of the soft support strip on the underwear is easily exposed, thus affecting the appearance.

[0004] In view of the above-mentioned technical problems, this utility model is proposed in this study. [Utility Model Content]

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a supportive bra, including a support part and a connecting part. The connecting part is integrally connected to the support part and is a one-piece garment on the bra, forming a side panel and a back panel. The back panel includes at least an inner layer and an outer layer, or an inner layer, a middle layer, and an outer layer. The back panel is provided with an elastically deformable back panel support strip, which is disposed in the interlayer of the bra and separated from the outer layer. This application, by providing an elastically deformable back panel support strip at the back panel, can adapt to the dynamic deformation of the chest during human activity, providing a comfortable support function. The separation of the back panel support strip from the outer layer improves its concealment, avoids friction between the back panel support strip and external clothing, and prevents the back panel support strip from falling off due to prolonged friction, thus improving the durability of the bra.

[0006] This utility model is achieved through the following technical solution:

[0007] A supportive bra includes a support portion for supporting the breasts and connecting portions on both sides of the support portion. The connecting portions are integrally connected to the support portion, and the support portion and connecting portions are one piece on the bra. The connecting portions form side panels near the support portion. A gusset is formed at the lower part of the support portion, and the gusset is provided with a gusset support strip that is elastically deformable for supporting the breasts. The gusset includes at least an inner layer and an outer layer. The gusset support strip is bonded to the inner layer and is separately disposed from the outer layer. Alternatively, the gusset includes an inner layer, a middle layer, and an outer layer. The gusset support strip is bonded to the middle layer and is separately disposed from both the outer layer and the inner layer.

[0008] As described above, in a type of supportive underwear, the underband includes at least an inner layer and an outer layer, and the underband support strip is bonded to the inner layer on the side opposite to the outer layer.

[0009] As described above, in a type of supportive underwear, the underband includes an inner layer, a middle layer, and an outer layer, and the underband support strip is bonded to the middle layer on one side opposite to the inner or outer layer.

[0010] As described above, the side panel of a supportive bra includes at least an inner layer and an outer layer. The side panel is provided with a side panel support strip that can elastically deform to support and gather the accessory breast tissue. The side panel support strip is bonded to one side of the inner layer opposite to the outer layer.

[0011] As described above, the side panel of a supportive bra includes an inner layer, a middle layer, and an outer layer. The side panel is provided with a side panel support strip that can elastically deform to support and gather the accessory breast tissue. The side panel support strip is bonded to the middle layer on the side opposite to the inner or outer layer.

[0012] As described above, in a type of supportive underwear, a center gore is formed in the middle of the lower part of the support area, and the underband support strip is composed of two symmetrically arranged sections opposite the center gore.

[0013] As described above, in a type of supportive underwear, a center gore is formed in the middle of the lower part of the support area, and the underband support strip is composed of a single section and is symmetrically arranged relative to the center gore.

[0014] As described above, in a type of supportive underwear, the side support strip is arranged longitudinally along the side length direction.

[0015] As described above, in a type of supportive underwear, the middle layer is a yarn layer, and the inner and outer layers are fabric layers.

[0016] As described above, in a type of supportive bra, the underband support strip and side support strip are made of silicone.

[0017] Compared with the prior art, the supportive underwear of this utility model has the following advantages:

[0018] 1. This application improves the durability, invisibility, and comfortable support performance of the underwear by combining a multi-layer fabric structure and an elastically deformable underwire support strip. In daily wear, the underwear can provide stable support, reduce discomfort during chest movement, and maintain a smooth and beautiful appearance.

[0019] 2. In this application, the underwire support strip and the side support strip are placed in the middle of the interlayer between the support part and the connecting part, and smoothly contact the skin on the inner skin side, which has an anti-slip and fixing function, and helps the bra structure to better support the breast.

[0020] 3. The middle layer of this application is made of gauze material, which helps airflow between the layers of the underwear. Especially in summer, it can prevent the chest from being in a stuffy environment for a long time, further providing good breathability and increasing wearing comfort.

[0021] 4. In this application, the cross-sections of the underrun support bar and the side support bar are D-shaped. The arc structure of the D-shaped cross-section is easier to bend evenly under stress, and the deformation stress is dispersed, which is beneficial to improving the rebound efficiency.

Detailed Implementation Methods

[0038] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] like Figure 1-7 As shown, this utility model includes a supportive bra, comprising a support portion 1 for supporting the breast and connecting portions 2 on both sides of the support portion 1. The connecting portions 2 are integrally connected to the support portion 1. A side panel 31 is formed in the area of ​​the connecting portions 2 near the support portion 1. A gusset 32 ​​is formed at the lower part of the support portion 1. The gusset 32 ​​is provided with a gusset support strip 41 that is elastically deformable for supporting the breast. The gusset 32 ​​includes at least an inner layer 301 and an outer layer 302. The gusset support strip 41 is bonded to the inner layer 301 and is separately disposed from the outer layer 302. Alternatively, the gusset 32 ​​includes an inner layer 301, a middle layer 303 and an outer layer 302. The gusset support strip 41 is bonded to the middle layer 303 and is separately disposed from both the outer layer 302 and the inner layer 301.

[0040] The support section 1 is the main functional part of the bra, designed to provide effective support for the breasts. Both sides of the support section 1 are connected to the connecting sections 2 to form a complete bra structure. The side panels 31 are specific areas of the connecting sections 2 near the support section 1, primarily serving to provide auxiliary support for the breasts. The underband 32 typically has good elasticity and support capabilities to adapt to the natural shape of the breasts and provide sufficient support. Through the design and fabric selection of the support section 1, proper support and lift are ensured for the breasts, thereby improving the wearer's posture and comfort.

[0041] The underwear may include a fabric structure comprising at least an inner layer 301 and an outer layer 302, or an inner layer 301, a middle layer 303, and an outer layer 302. Each layer of fabric is cut and then stacked at corresponding positions to form the underwear structure. The stacking method is not limited to sewing or heat pressing. The multi-layered fabric structure of the underwear, through cutting and stacking processes, achieves complex support and comfort functions. The connecting part 2 and the support part 1 work together to optimize pressure distribution and improve the wearer's comfort.

[0042] The underwire support strip 41 is elastic and deformable, adapting to the dynamic changes in the breast. During wear, the support strip deforms elastically with breast movement, avoiding the pressure and marks caused by the rigid support of traditional underwires. This elastic deformation allows the bra to provide stable support without excessive pressure on the breast, thus preventing marks on the skin and greatly reducing sagging during breast movement. Especially during periods of significant breast movement, such as exercise or daily activities, the elastic deformation of the underwire support strip 41 effectively reduces breast sagging, providing a more comfortable wearing experience.

[0043] In this design, a connecting part 2 and a supporting part 1 are formed within the multi-layered fabric of the underwear. In a two- or three-layered structure, the underbelly support strip 41 is bonded to the inner layer 301 or the middle layer 303. The underbelly support strip 41 is separate from the outer layer 302. The outer layer 302 is not bonded to the underbelly support strip 41 at the underbelly 32. Because the supporting part 1 has a multi-layered fabric structure, the multiple fabric layers buffer and adjust each other, preventing stress concentration and dispersing stress, reducing wrinkles caused by wearing or daily activities, enhancing wrinkle resistance, and thus improving the durability of the underwear.

[0044] Furthermore, the underband support strip 41 is separately positioned from the outer layer 302 and does not rub against external clothing. Therefore, the outline of the underband support strip 41 will not be visible on external clothing, enhancing its invisibility. It also avoids friction between the underband support strip 41 and external clothing, reducing the risk of it falling off due to friction. In daily wear, the invisible design of the underband support strip 41 makes the bra appear smoother and prevents its outline from affecting the overall aesthetics.

[0045] In this application, an elastically deformable underbust support strip 41 is provided at the underbust 32, which can adapt to the dynamic deformation of the chest during human activity and provide a comfortable support. The underbust support strip 41 is separately set from the outer layer 302, which improves the concealment of the underbust support strip 41, avoids friction between the underbust support strip 41 and external clothing, and prevents the underbust support strip 41 from falling off due to long-term friction, thereby improving the durability of the underwear.

[0046] like Figure 2 , Figure 5a , Figure 5b As shown, as a further technical solution of this application, when the underwear has two layers of fabric, the underband 32 includes at least an inner layer 301 and an outer layer 302, and the underband support strip 41 is bonded to the inner layer 301 on the side opposite to the outer layer 302. Further, the side panel 31 includes at least an inner layer 301 and an outer layer 302, and the side panel 31 is provided with a side panel support strip 42 for supporting and gathering the elastically deformable accessory breast tissue; the side panel support strip 42 is bonded to the side of the inner layer 301 opposite to the outer layer 302. Alternatively, when the underwear has three layers of fabric, such as... Figure 3 , Figure 4 , Figure 6a , Figure 6b , Figure 6c As shown, the underband 32 includes an inner layer 301, a middle layer 303, and an outer layer 302. The underband support strip 41 is bonded to the middle layer 303 on one side relative to the inner layer 301 or the outer layer 302. Further, the side panel 31 includes an inner layer 301, a middle layer 303, and an outer layer 302. A side panel support strip 42, which is elastically deformable and supports and gathers the accessory breast tissue, is provided at the side panel 31. The side panel support strip 42 is bonded to the middle layer 303 on one side relative to the inner layer 301 or the outer layer 302. The side panel support strip 42 at the side panel 31 of the bra can gather the accessory breast tissue inwards while generating upward elastic support, which helps to optimize the breast shape curve and achieve a three-dimensional gathering effect. The underband support strip 41 and the side panel support strip 42 can be fixed to a preset trajectory on the inner layer 301 or the middle layer 303 using a dispensing process. After the dispensing trajectory cures, it forms an elastic support structure, which helps to improve the stability of the interface adhesion. Compared to the method of bonding the underpin support strip 41 and the side support strip 42 with glue, the method of forming and curing the underpin support strip 41 and the side support strip 42 by applying glue to the inner layer 301 or the middle layer 303 results in a stronger bond, less detachment, and a more reliable structure.

[0047] Because the underband support strip 41 and the side support strip 42 are located between the layers of the bra at corresponding positions, unlike traditional bra designs that use the underband support strip 41 and the side support strip 42 to fix multiple layers of fabric, the underband support strip 41 and the side support strip 42 in this application have elastic deformation space during dynamic activities, preventing the cups from shifting and protecting the breasts while providing good support. At the same time, in the two- or three-layer structure of the bra, the underband support strip 41 and the side support strip 42 are bonded to the inner layer 301 or the middle layer 303 on the side opposite the outer layer 302. The underband support strip 41 and the side support strip 42 do not come into direct contact with the skin, avoiding prolonged direct contact between the support strips and the skin, which could lead to poor breathability or even allergic reactions. This application is applicable to designs suitable for sports, daily wear, and extended wear scenarios, and is not limited to underwear, sports bras, or sports pants that are worn close to the body and have shaping and support functions.

[0048] Furthermore, some existing underwear designs that directly adhere soft support strips to the skin suffer from insufficient breathability. For example, when the strips are bonded to the inner surface of the inner layer 301 and adhere to the skin, they hinder skin ventilation and perspiration, potentially leading to stuffiness and even skin sensitivity with prolonged wear. As a further technical solution in this application, specifically, the middle layer 303 is a yarn layer, while the inner layer 301 and outer layer 302 are fabric layers. The fabric layer of the inner layer 301 has a certain degree of elasticity and possesses a certain degree of sweat absorption and breathability, making the underwear skin-friendly and breathable. The fabric layer of the underwear can also be made of textiles, knitted materials, etc. The unbonded separation design at the underband 32 of the inner layer 301 or middle layer 303 creates an airflow gap while isolating it from external clothing. The gaps between the multiple fabric layers allow airflow to pass between the layers of the underwear, especially in summer, preventing the chest from being in a stuffy environment for extended periods, further providing good breathability and increasing wearing comfort.

[0049] Furthermore, when the underwear fabric has a three-layer structure, the mesh of the middle layer 303 serves as the bonding base, ensuring the bonding strength of the underwire support strip 41 and the side support strip 42, while also enhancing breathability through the pores of the mesh layer. Additionally, the elastic fabrics of the inner layer 301 and the outer layer 302 stretch synchronously without restricting the elastic deformation of the underwire support strip 41, ensuring the fabric's natural stretch and ease of movement.

[0050] Furthermore, the inner layer 301 or the middle layer 303 provides a stable adhesive base for the underband support strip 41 and the side support strip 42, positioning them between the support portion 1 and the connecting portion 2, ensuring breathability while maintaining wearing comfort. Additionally, the skin-contacting side of the inner layer 301 smoothly adheres to the skin, providing anti-slip and securing properties, and further assisting the bra structure in better supporting the breasts.

[0051] like Figure 1-7 As shown, as a further technical solution of this application, the side support strip 42 is longitudinally arranged along the length direction of the side panel 31. The longitudinally arranged side support strip 42 provides upward support at the side panel 31, preventing discomfort from the cups shifting during activity. The side support strip 42 can adapt to the dynamic deformation of the chest during human activity. Furthermore, multiple side support strips 42 are arranged in parallel to enhance the support and lift effect. Simultaneously, wrinkles are less likely to form at the side panel 31 during daily activities, preventing the bra's comfort from being affected by deformation and increasing the bra's lifespan. The shape of the side support strip 42 can be wavy, straight, or curved, and it runs longitudinally at the side panel 31.

[0052] Alternatively, the side panel 31 can provide support in another way (not shown in the figure). The side panel 31 is located between the inner layer 301 and the outer layer 302, or between the inner layer 301, the middle layer 303, and the outer layer 302. Multiple side panel support strips 42 are used to bond the inner layer 301 and the outer layer 302, or the inner layer 301, the middle layer 303, and the outer layer 302. These multiple side panel support strips 42 form a block-shaped area, which is used to bond the inner layer 301 and the outer layer 302, or the inner layer 301, the middle layer 303, and the outer layer 302. The bonded side panel 31 provides stable support, prevents the fabric from wrinkling during wear, maintains softness and comfort, and does not cause pressure on the skin. The side panel support strips 42 can be made of silicone or TPU material.

[0053] Similarly, silicone or TPU adhesives can be used to bond multiple layers of fabric in underwear, reducing tedious sewing processes. The inner layer 301, outer layer 302, or the inner layer 301, middle layer 303, and outer layer 302 are bonded together with adhesive to form an adhesive area. The bonded area is smooth and clean, fits the skin better, and is more comfortable to wear.

[0054] like Figure 7 As shown, the underwear also includes shoulder straps 35 and fixing parts 36, which are closely connected to the overall structure of the underwear. This increases the interaction between the side support strips 42 and the overall structure of the underwear, so that the stress experienced by the wearer when wearing the underwear can be evenly distributed throughout the underwear, thereby improving the overall support and bearing effect.

[0055] like Figure 5b As shown, as a further technical solution of this application, a "heart-shaped" structure 33 is formed in the middle of the lower part of the support portion 1, and the lower support strip 41 is composed of two symmetrically arranged sections opposite the "heart-shaped" structure 33. (Refer to...) Figure 1 , Figure 6b The underarm support strip 41 is composed of a single section and is symmetrically positioned relative to the center of the breast 33. The underarm support strip 41 can be in a continuous wave shape, with the center of the breast 33 serving as the connection point. The underarm support strip 41 is symmetrically positioned on both sides of the center of the breast 33, providing symmetrical elastic support to adapt to the dynamic deformation of the breast, so that the breast is continuously and evenly supported, thereby improving support stability. The wearer feels comfortable during wear without excessive pressure.

[0056] like Figure 2-4As shown, as a further technical solution of this application, the underbody support strip 41 and the side support strip 42 are made of silicone. Molten silicone is bonded together in the corresponding inner layer 301 or middle layer 303 using a hot-melt bonding process, and then molded into the underbody support strip 41 and the side support strip 42. This method ensures that the silicone is firmly bonded and evenly distributed in the inner layer 301 or middle layer 303. The underbody support strip 41 and the side support strip 42 have a D-shaped cross-section, with the arc-shaped surface facing the outer layer 302, and their surfaces do not adhere to the outer layer 302. Compared to traditional circular or flat underbody support strips 41 and 42, which are prone to localized stress concentration and plastic deformation during deformation, the D-shaped arc structure is more easily and evenly bent under stress, dispersing deformation stress and improving rebound efficiency.

[0057] Among them, the support part 1 and the connecting part 2 can be set as a single piece on the underwear, without any seams, and the whole is comfortable and skin-friendly.

[0058] like Figure 2-7 As shown, as a further technology of this application, the support part 1 also includes a cup 34 formed by thermoforming 3D molding. The cup 34 is arc-shaped, conforming to the structural curve of the human chest. The support part 1 can be formed by thermoforming 3D molding through a thermoforming mold to form the cup 34 portion. Specifically, the formed cup 34 portion is arc-shaped and conforms to the structural curve of the human chest to ensure comfort and support during wear. Compared with the traditional method of forming the cup 34 by sewing multiple layers of fabric, the one-piece fabric produced by thermoforming 3D molding has no seams and is more comfortable to wear. It should be noted that the thermoforming process, through precise temperature and pressure control, allows the fabric to form an ergonomic three-dimensional curved structure in the mold, enabling the rapid production of support parts 1 of different sizes and accelerating production efficiency.

[0059] Furthermore, to meet the needs of people with different breast shapes for shaping beautiful lines in their bras, a cup pad (not shown in the diagram) can be added at cup 34. The size and shape of the cup pad match the bra, and by filling the internal space of cup 34, it can compensate for the lack of natural breast curves, avoid the embarrassment of empty cups, and thus increase the fullness and firmness of the breasts. When the bra structure is three-layered, the cup pad can be placed on the middle layer 303, overlapping with the position of cup 34, which can modify the breast lines and better protect the breasts.

[0060] This application also relates to a manufacturing process for a supportive bra. Since both the underband support strip 41 and the side support strip 42 are manufactured using this process, for ease of description, the underband support strip 41 and the side support strip 42 will be referred to as support strips below. This manufacturing process relates to the aforementioned supportive bra and includes the following steps:

[0061] S1. Apply glue: Apply glue to the inner layer 301 or the lower strip 32 corresponding to the middle layer 303 using a glue dispensing device, and apply glue according to a preset trajectory to form a molten glue dispensing trajectory.

[0062] S2. Baking: Bake the inner layer 301 or the middle layer 303 from step S1. Set the baking temperature to 120-140℃ and the baking time to 8-12 minutes to cure the adhesive trail and form a support strip.

[0063] S3. Connecting: The inner layer 301 with support strips is superimposed on the outer layer 302 to form a supporting part 1 and a connecting part 2; or the middle layer 303 with support strips is superimposed on the inner layer 301 and the outer layer 302 to form a supporting part 1 and a connecting part 2.

[0064] Step S1 further includes applying adhesive to the side surface 31 corresponding to the inner layer 301 or the middle layer 303. The adhesive is applied to the side surface 31 corresponding to the inner layer 301 or the middle layer 303 by a dispensing device and the adhesive is applied according to a preset trajectory to form a molten dispensing trajectory.

[0065] Working Process: First, the dispensing device heats the support strip material to its melting temperature, turning it into a liquid or semi-solid state. This process requires precise temperature control to ensure the support strip material completely melts without decomposition or burning. Second, the heated support strip material enters a molten state, facilitating subsequent dispensing operations. Due to the good fluidity and adhesion of the molten material, it can evenly cover the designated locations. The dispensing device precisely positions the molten support strip material on the preset tracks at the underside 32 and side support 31 of the inner layer 301 or the middle layer 303. A baking process then transforms the molten support strip material into a solid state, forming the underside support strip 41 and the side support strip 42. Automated bonding equipment ensures consistent glue application across the symmetrical support strips through precise dispensing, preventing uneven deformation due to glue quantity differences. This ensures accurate glue application tracks for the symmetrical support strips, reducing errors from manual dispensing and improving production efficiency and labor costs.

[0066] Among them, the molding process of underwear products can be selected in different ways according to design requirements: it can be combined and connected by sewing, gluing and other processes, or it can be achieved by using one-piece cut fabric combined with hot pressing 3D molding technology to achieve a three-dimensional shape.

[0067] It should be noted that the aforementioned dispensing device belongs to the prior art. Chinese utility model document CN219324382U discloses a specific structure for an underwear dispensing machine, including a material tank, a pump body, and a dispensing table. The dispensing table is equipped with a three-axis motion assembly to coordinate its dispensing motion. This dispensing machine can achieve rapid, multiple dispensing operations. Furthermore, the dispensing head's movement can be controlled by the X-axis, Y-axis, and Z-axis motion assemblies. In this application, the dispensing head can be controlled through specific operational settings to ensure continuous dispensing of adhesive, forming a dispensing trajectory that creates a continuous straight, wavy, or arc-shaped dispensing path on the desired fabric.

[0068] Building upon this, the dispensing device can also be equipped with a precise positioning device, such as an adsorption component added to the worktable. This adsorption component is used to precisely position the inner layer 301 or the intermediate layer 303 at a preset position on the worktable before applying the adhesive. The adsorption component can be an electrostatic chuck. It should be noted that electrostatic chucks are existing technology and will not be discussed further here.

[0069] The curing process determines the bonding strength and stability of the support strip, therefore, strict control of time and temperature is necessary. Specifically, when the baking equipment is set to a baking temperature of 130℃ and a baking time of 10 minutes, a curing effect with better interfacial bonding strength is obtained.

[0070] The manufacturing process of supportive underwear also includes a cutting step, in which each layer of fabric is cut to the required size and shape.

[0071] In addition, since underwear comes in different sizes, for inner layers 301 or middle layers 303 of different sizes and shapes, before applying glue, the size drawing of inner layer 301 or middle layer 303 is first input into the control module of the glue dispensing device to confirm the position of the preset trajectory and the amount of glue used.

[0072] In this application, the support strip material is heated and molten using a dispensing device. It is then precisely positioned at the bottom support 32 and side support 31 of the inner layer 301 or the middle layer 303. The dispensing is applied along a preset trajectory, and the molten support strip material is continuously distributed on the interface of the inner layer 301 or the middle layer 303, thus forming a dispensing trajectory. After baking and curing, the bottom support strip 41 and the side support strip 42 are formed. Compared with traditional processes, the precise dispensing technology effectively reduces the risk of glue overflow, reduces unnecessary material waste, thereby reducing production costs. Furthermore, the precise control of the dispensing trajectory ensures the consistency of the support strip shape, improving production efficiency and product consistency.
