Abstract
Description
Technical Field
[0001] This invention relates to the field of underwear and functional clothing, specifically to a bra cup, bra, garment, and method for manufacturing the bra cup with elastic support. Background Technology
[0002] Traditional bra cups are typically made from multiple layers of fabric (such as cotton or synthetic fibers) and filling (such as sponge) through a heat-molding process. In this process, the cup blank is placed in a high-temperature mold, where its fibers or polymer chains deform under heat and pressure, "memorizing" a new 3D curved shape, thus achieving the 3D three-dimensional shape of the cup. The limitation of this method is that the fabric and cotton that make up the main body of the cup inherently lack excellent, durable elastic recovery stress. Once shaped, its shape and support are largely static.
[0003] To enhance comfort during activities, bras on the market are made with elastic fabrics (such as Lycra). However, these bras often sacrifice the structural support of the cups in pursuit of overall fabric elasticity, resulting in insufficient support, especially when supporting larger breasts or engaging in high-intensity exercise. On the other hand, bras with rigid support structures such as underwires, while providing static support, have high structural rigidity and cannot adaptively adjust to body movements and postures. This not only easily leads to pressure and uncomfortable marks during activities, affecting comfort over long-term wear, but also lacks effective force cushioning and redistribution during dynamic activities.
[0004] In view of the above-mentioned technical problems, this invention is proposed. Summary of the Invention
[0005] The technical problem to be solved by this invention is to provide a bra cup, bra, garment, and a method for manufacturing the bra cup with elastic support, thereby solving at least one of the aforementioned technical problems. The core of this invention lies in providing a bra cup with elastic support, comprising a cup body and an elastic support body made of a heat-resistant elastic polymer. This elastic support body is pre-attached to the cup blank and stretches and deforms along with the material layers during the heating and molding process of the cup body. After the material layers are shaped, the support body maintains a stretched state of elastic strain due to the constraint of the material, allowing the corresponding parts of the cup body to obtain continuous elastic strain or a tendency for elastic strain. This invention overcomes the problems of traditional bra cups, such as empty cups and breast displacement caused by a lack of dynamic rebound force, as well as poor comfort and inaccurate shaping caused by uneven static distribution of support force.
[0006] To solve the above-mentioned technical problems, the present invention proposes a bra cup with elastic support, comprising a bra cup body and an elastic support body. The elastic support body is made of a heat-resistant elastic polymer that resists memory deformation. The elastic support body is elastically attached to the corresponding part of the bra cup body, so that the corresponding part of the bra cup body maintains elastic strain or elastic strain trend to provide support for the wearer's breast tissue in real time.
[0007] As described above, a bra cup with elastic support is provided, wherein the elastic support is made of polyurethane; at least a local area of the elastic support is stretched and deformed along the convex curved surface of the corresponding part of the 3D structured bra cup body by heat molding.
[0008] As described above, a bra cup with elastic support has a hollow structure; the hollow structure is formed by at least two sets of lines in different directions interwoven to form a mesh pattern.
[0009] As described above, a bra cup with elastic support has a cup portion on its body for accommodating the breast; the elastic support body is located in the lower cup portion of the cup portion to support and lift the breast upwards and inwards.
[0010] As described above, in a bra cup with elastic support, the density of the mesh-like lines of the elastic support gradually decreases from the bottom to the top of the lower cup, so that the support and bolstering effect of the lower cup gradually weakens from the bottom to the top.
[0011] As described above, a bra cup with elastic support includes at least two elastic regions located at different parts of the bra cup body.
[0012] As described above, a bra cup with elastic support includes a first elastic region covering the lower cup portion for supporting and supporting the breast, and a second elastic region located in the side panel portion for shaping.
[0013] As described above, a bra cup with elastic support includes a first elastic region covering the lower cup portion for supporting and supporting the breast, and a second elastic region located in the side panel portion for shaping.
[0014] As described above, a bra cup with elastic support further includes a third elastic region for lifting the accessory breast tissue. The third elastic region extends upward from the side of the first elastic region near the bend in the cup body, along the outer edge of the cup portion to the ear portion in the cup body.
[0015] As described above, in a bra cup with elastic support, the density of the mesh lines in the first elastic region and the second elastic region differs to provide differentiated deformation and support characteristics.
[0016] As described above, in a bra cup with elastic support, the density of the first elastic region is greater than that of the second elastic region, so that the supporting effect of the first elastic region is greater than that of the second elastic region.
[0017] The present invention also relates to a bra, including the aforementioned elastically supported cup, wherein the cup body includes at least an inner layer that conforms to one side of the breast and an outer layer that is away from the breast; the inner layer includes a lining fabric layer and a lining cotton layer stacked from the outside to the inside relative to the cup body, and the outer layer includes an outer cotton layer and an outer fabric layer stacked from the inside to the outside relative to the cup body; the elastic support is attached to the surface of the lining cotton layer facing the outer layer.
[0018] The bra described above is any one of a multi-size bra, a sports bra, or a regular bra.
[0019] The present invention also relates to a garment, wherein the cup body includes an inner layer that conforms to one side of the breast and an outer layer that is away from the breast, the inner layer being a lining layer and the outer layer being an outer fabric layer; and an elastic support is attached to the surface of the lining layer facing the outer fabric layer.
[0020] This invention also relates to a method for manufacturing a bra cup with elastic support, comprising the following steps:
[0021] S1. Provide a cup preform material, the cup preform material including a first material layer for forming an inner layer that conforms to one side of the breast, and a second material layer for forming an outer layer that is away from the breast.
[0022] S2. Apply gel-like polyurethane adhesive to the surface of a planar first material layer according to a pre-defined pattern. After heat curing, an elastic support with a specific structure is formed. The first material layer and the elastic support constitute a composite material layer.
[0023] S3. The composite material layer and the second material layer are stacked to form a cup stack; and the cup stack is heated and molded to form a cup body with a 3D structure.
[0024] During the heating and molding process, the elastic support body stretches and elastically strains along with the first material layer, and remains bonded to the 3D curved surface of the cup body. The elastic support body causes the cup body to maintain elastic strain or elastic strain trend accordingly under its own elastic strain or elastic strain trend, thereby providing real-time elastic strain support for the cup body.
[0025] Compared with existing technologies, the present invention, which discloses a bra cup, bra, garment, and bra cup manufacturing method with elastic support, has the following advantages:
[0026] 1. This invention uses polyurethane material with high resilience and resistance to shape memory to create an elastic support body. After being heated and molded within the bra cup body, it maintains elastic strain or an elastic strain tendency. This invention allows for elastic expansion and contraction according to changes in breast shape during wear, consistently providing active and continuous inward elastic strain support. This solves common problems such as gaps between the bra cup and breast, and breast displacement or misalignment within the bra cup caused by body activity and menstrual cycle changes, significantly improving wearing stability and comfort.
[0027] 2. This invention divides the elastic support body into multiple elastic regions corresponding to different functional parts of the bra cup, forming a directional support structure with clear functional guidance. Each region can be designed independently, working together to achieve support, shaping, and lifting functions, thereby providing a more comprehensive and precise three-dimensional coverage effect.
[0028] 3. This invention designs the elastic support body as a hollow mesh structure, and allows for different mesh weave densities in different areas. This structure enhances breathability and lightweight feel, while also controlling the deformation capacity and support of each part through variations in the density of the lines, achieving a smooth transition of support and functional zoning, thereby optimizing overall mechanical distribution and wearing comfort.
[0029] 4. This invention utilizes a manufacturing method that involves coating and curing an elastic support onto a planar material layer, followed by overall 3D molding. This method efficiently integrates the elastic support with the cup body molding process, avoiding the need for gluing or sewing, and ensuring that the support elastic is precisely positioned and firmly bonded in the finished product.
[0030] 5. In this invention, the cup with an elastic support body having elastic stress is used as the core component, which can be flexibly adapted to various clothing categories that require breast support, such as bras, shapewear, sports bras, swimwear, dresses, etc., thereby expanding the application compatibility of the cup.

[0043] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0044] For those skilled in the art, the bra cup, as the core component of underwear, typically comprises various parts corresponding to different positions within the cup, including the cup portion 101, the flap portion 102, the underband 103, the side panel portion 104, the cleavage portion 105, the center gore 106, and the nipple peak 107. The shoulder straps 108 are attached to the upper edge of the cup body 100 as additional accessories. The middle portion on both sides of the cup body 100 is generally defined as the cup portion 101, which accommodates both breasts, and the nipple peak 107 is located in the middle of the cup portion 101, corresponding to the nipple area. The area between the two cup portions 101 is the center gore 106. The area where the cup portion 101 connects to the shoulder strap in the cup body 100 is the flap portion 102. The area on both sides of the cup body 100 near the armpit is the cleavage portion 105. The area on both sides of the cup body 100 near the underarm is the side panel 104.
[0045] like Figures 1 to 6As shown, the present invention includes a bra cup with elastic support, comprising a cup body 100 and an elastic support 40. The elastic support 40 is made of a heat-resistant elastic polymer that resists shape memory deformation. The elastic support 40 is elastically attached to a corresponding portion of the cup body 100, so that the corresponding portion of the cup body 100 maintains elastic strain or elastic strain tendency to provide real-time support for the wearer's breast tissue. At least a local area of the elastic support 40 is stretched and deformed along the convex curved surface of the corresponding portion of the 3D structured cup body 100 through heat molding.
[0046] The elastic support 40 is made of a heat-resistant elastic polymer, whose key characteristic is its resistance to heat-induced permanent deformation. The polymer is polyurethane, an environmentally friendly material with good tensile strength and elastic recovery. Its flexible segmental structure allows the material to quickly return to its original shape after repeated stretching, suitable for the frequent movements required by bras and underwear. In a preferred embodiment, this elastic support 40 is attached to a designated area (such as the bra cup portion 101) of the cup body 100 in an elastically deformable manner, and these portions of the cup exhibit continuous elastic deformation or a tendency to elastically deform.
[0047] During the manufacturing process of the bra cup, the cup blank, which includes the elastic support 40, is composed of multiple layers of materials such as fabric and cotton. The cup blank undergoes a heat-molding process. During this process, the fabric and cotton materials are heat-set to obtain the 3D convex curved surface shape of the mold; the pre-attached elastic support 40 is stretched along with the deformation of its attached layers and adaptively attaches to the curved surface, especially in areas with large curvature changes, where the stretching is more pronounced. Due to the high elasticity and heat resistance of polyurethane, after the cup undergoes heat molding, the elastic support 40, because it is not heat-set, retains its elastic recovery ability and maintains its elastic strain or elastic strain tendency. Specifically, the working temperature during the heat molding process is between 190-220℃, and the heat resistance temperature of the polyurethane is higher than the temperature during the molding process of the cup blank.
[0048] Therefore, in the finished bra cup, the elastic support 40 stores elasticity due to its stretched state, continuously generating a restoring stress pointing towards the center of the cup portion 101, thereby providing an inward fit and upward support. In this application, by adding the elastic support 40 to the heat-set material layer, its continuous rebound force enables the corresponding part of the bra cup body 100 to have an inherent elastic strain support function.
[0049] The cup body 100 can accommodate breast size deviations within a certain range. Its elastic deformation trend is that when the breast size changes, the cup body 100 can be further stretched to expand the cup volume, or it can elastically recover and reduce the cup volume as the breast size shrinks, so that the material layer can dynamically conform to the breast contour and improve the fit.
[0050] For example, when the size of the breasts changes normally or slightly due to menstruation, exercise, or other factors, the elastic support 40 can adapt to the size fluctuations through further elastic stretching. At the same time, its continuous rebound force ensures that the entire cup always fits the surface of the breast, effectively avoiding the "empty cup" phenomenon. Its restoring stress can distribute part of the breast weight, and through the bra's shoulder straps 108 and side panels 104, the load is evenly distributed to the shoulders and back, improving wearing comfort.
[0051] In areas of the bra cup where deformation is minimal or nonexistent, the elastic support 40 acts as a built-in skeleton, helping to enhance the structural stability of the cup. This helps prevent the cup from wrinkling, deforming, or sagging prematurely after being subjected to stress or repeated wear, thereby extending the product's lifespan.
[0052] The elastic support 40 can be directly molded onto the corresponding material layer before cup molding. For example, gel-like polyurethane can be directly adhered to the surface of the cotton or fabric layer, and after curing, a support structure is formed. Subsequently, this composite layer is laminated with other materials and then heated and molded. The elastic support 40 is firmly bonded to the material layer during the curing process, and no additional adhesive layer is required, simplifying the production process and improving work efficiency.
[0053] This bra cup has a wide range of sizing adaptability, which can not only fit the fluctuation of breast size of the same wearer at different physiological stages or states, but also adapt to different user groups within a certain size range. This helps to improve the wearing inclusivity, while helping merchants reduce the segmentation of sizes and simplify inventory management.
[0054] like Figure 6As shown, an example of the specific structure of an adaptive multi-size bra is illustrated, including a cup body 100, which comprises an inner layer 10 and an outer layer 20. The cup body 100 forms a breast cup portion 101 with a 3D structure for accommodating the breast. The outer layer 20 has a cup depth of H1, which is constant; the cup depth of the inner layer 10 is H2, which is variable, and H1>H2 is satisfied in normal conditions or when worn. Specifically, an adjustment space 30 is formed between the inner layer 10 and the outer layer 20 due to the difference in cup depth. The adjustment space 30 is filled with an elastic low-density cotton layer 31, which can elastically deform to adapt to the curve of the breast. On this basis, an elastic support 40 is disposed on the surface of the inner layer 10 away from the breast in the cup body 100, so that the material of the inner layer 10 itself has elastic strain or elastic strain tendency, which can act to support the breast through the inner layer 10. Furthermore, the inner layer 10 includes a lining fabric layer 11 and a lining cotton layer 12 stacked from the skin-contact side toward the outer garment direction, and the outer layer 20 includes an outer cotton layer 22 and an outer fabric layer 21 stacked from the skin-contact side toward the outer garment direction. In this bra, the lining fabric layer 11, the lining cotton layer 12, the elastic support 40, the elastic low-density cotton layer 31, the outer cotton layer 22, and the outer fabric layer 21 are stacked sequentially from the skin-contact side toward the outer garment direction.
[0055] When the breast compresses the inner layer 10, the inner cotton layer 12 expands and deforms into the adjustment space 30, compressing the elastic low-density cotton layer 31 and causing it to undergo adaptive compression deformation. The main deformation occurs within the adjustment space 30, preventing the overall collapse of the cup 100. Because the surface of the inner layer 10 is provided with an elastic support body 40, it provides support and lift to the breast. In this adaptive multi-size bra, the elastic low-density cotton layer 31 in the adjustment space 30 dynamically adjusts to match the breast shape, avoiding unpleasant pressure and achieving a comfortable and snug fit.
[0056] like Figure 1 , Figure 4 , Figure 5As shown, the elastic support 40 has a hollow structure. Specifically, the hollow structure is formed by at least two sets of lines in different directions interwoven to form a mesh-like pattern, which can form a series of continuous hollow units. The shape of the hollow units can be designed as rhombus, round hole, or strip. Preferably, rhombus units are used, as they are more effective in providing uniform support and conforming to surface deformation. The hollow units ensure air circulation, which can significantly improve the stuffiness inside the cup and enhance the wearing comfort. The hollow structure itself is easy to undergo elastic deformation under stress, allowing the elastic support 40 to more flexibly conform to and respond to the curve changes of the breast surface, thereby enhancing the overall wrapping and fit. When the body movement causes the breast to shake unavoidably, this structure can absorb some energy through elastic strain and maintain a gentle and continuous wrapping of the breast tissue with its mesh structure, thereby helping to maintain the relative stability of the breast shape in dynamics, avoiding displacement or excessive shaking, and achieving dynamic stability of the breast.
[0057] like Figure 1 As shown, in one embodiment of the elastic support 40, the cup body 100 is provided with a breast cup portion 101 for accommodating the breast; the elastic support 40 is provided in the lower cup portion 1011 of the breast cup portion 101 to support and lift the breast upwards and inwards; the density of the mesh-like lines of the elastic support 40 varies continuously within the area of the lower cup portion 1011, forming a unified and undefined support structure. The breast cup portion 101 can be further divided into different areas according to support requirements. The upper half of the breast cup portion 101 is designated as the upper cup portion (not shown in the figure), and the lower half is designated as the lower cup portion 1011, which is the area primarily responsible for support.
[0058] In this design, the density of the mesh-like lines in the elastic support 40 gradually decreases from the bottom to the top of the lower cup portion 1011. This results in a gradual weakening of the support and bolstering effect of the lower cup portion 1011 from bottom to top, causing the elastic strain capacity of the elastic support 40 to vary in different areas of the lower cup portion: the top area is relatively sparse and more flexible, making it easier to accommodate and conform to the body; while the bottom area is denser and more supportive. The direction of the change in support force should be consistent with the direction of the change in density, naturally forming a transition within the lower cup portion 1011 where the support force gradually weakens from the bottom to the top, thus providing a more comfortable and natural support effect. This embodiment demonstrates that within the same elastic area, the density gradually changes, thus creating a natural transition in support force, which can improve the discomfort caused by abrupt changes in support force.
[0059] Furthermore, the elastic support 40 of the present invention can be divided into multiple elastic regions with different support characteristics according to the functional requirements of different parts of the bra cup, that is, to realize the differentiated design of the partition.
[0060] In an embodiment that includes multiple flexible regions, such as Figures 4 to 5 As shown, specifically, the elastic support 40 includes at least two elastic regions located at different parts of the bra cup body 100, covering the bra cup portion. The elastic support 40 has different elastic regions corresponding to different parts of the bra cup to achieve targeted support design.
[0061] The lower cup portion 1011 of the bra cup portion 101 is a first elastic region 411 used to support and hold the breast, mainly providing upward and inward support to support the weight of the breast; and a second elastic region 412 located in the side panel portion 104 for shaping, the second elastic region 412 providing lateral wrapping and shaping of the breast. Furthermore, the second elastic region 412 extends at least partially along the side panel portion 104 into the underband portion 103 in the cup body 100 to enhance the fixation and gathering effect on the lower side.
[0062] like Figure 4 As shown, the elastic support 40 further includes a third elastic region 413 for lifting the accessory breast tissue. The third elastic region 413 extends upwards along the outer edge of the cup portion 101 from the side of the first elastic region 411 near the bend 105 in the cup body 100 to the ear portion 102 in the cup body 100. The third elastic region 413 starts from the side of the first elastic region 411 adjacent to the bend 105, then extends along the upper outer edge of the cup portion 101 to the ear portion 102. Its function focuses on lifting and fixing the breast tissue in the anterior axillary region (corresponding to the location of the accessory breast tissue). This application enables the elastic support 40 to integrate multiple directional supports through different elastic regions, working together to achieve the beneficial effects of support, lift, and shaping.
[0063] To achieve targeted functionality, the density of lines in different elastic regions can be set to vary. In a typical example, the density of the first elastic region 411 is greater than that of the second elastic region 412. This makes the support of the first elastic region 411 greater than that of the second elastic region 412. The first elastic region 411 can provide more rigid and stronger upward and inward support, effectively supporting the weight of the breast and reducing the wearing burden on the shoulders and back.
[0064] It should be noted that the elastic support 40 is made of heat-resistant and elastic polyurethane that resists shape memory deformation. The material itself has the same physical properties such as elastic modulus and resilience, and its fundamental properties are not changed by the fact that it is attached to the heat-set material layer after being stretched and fixed to the curved surface of the cup. The difference in support characteristics between the elastic regions is mainly achieved by designing different line densities, and the degree of intersecting and overlapping of the mesh-like lines that make up the elastic regions.
[0065] In summary, the two design approaches described above—namely, density design within a single area and density variation design between different areas—are not mutually exclusive in this invention. Instead, they can be combined and applied to the same product to achieve superior overall performance. For example, a specific bra cup product can simultaneously feature a density variation design that decreases from bottom to top within the first elastic region 411 to achieve a smooth transition in support. At the same time, the overall or average density of the first elastic region 411 should be greater than the sparseness of the second elastic region 412 to achieve differentiated support between regions. This application, combining internal density variation with targeted support between regions, allows for a more detailed and scientific distribution of the mechanical properties of different parts of the bra cup, and is one of the important implementation methods protected by this invention.
[0066] like Figures 1 to 6 As shown, this application also discloses a method for manufacturing a bra cup with elastic support, including the following steps:
[0067] S1. Provide a cup preform material, the cup preform material including a first material layer for forming an inner layer 10 that conforms to one side of the breast, and a second material layer for forming an outer layer 20 that is away from the breast.
[0068] The first material layer is used to subsequently form the inner layer 10 of the cup body 100 that conforms to the breast side, and the second material layer is used to form the outer layer 20 that is away from the breast side. The first material layer can be a cotton layer and / or a fabric layer. Similarly, the second material layer is not limited to a cotton layer and / or a fabric layer. Depending on the type of bra, the cup material may also include a functional layer material located between the inner layer 10 and the outer layer 20.
[0069] S2. A gel-like polyurethane adhesive is applied to the surface of a planar first material layer according to a pre-defined pattern. Then, it is heated and cured to solidify the polymer, allowing it to firmly bond with the first material layer, thus forming a specific structured elastic support 40 on the surface of the first material. At this point, the first material layer and the attached elastic support 40 together constitute a composite material layer. This pattern accurately corresponds to the partition layout, texture shape, and density design of the elastic support 40 required for the finished bra cup. It should be noted that heating and molding, and curing, are two independent heat treatment steps. The elastic support 40 polymer can be pre-attached to the corresponding cotton or fabric layer in the first material layer by extrusion, brush printing, or roller coating. The key to this step is to pre-apply and fix the specifically designed elastic support 40 to the base material in a planar state.
[0070] S3. The composite material layer and the second material layer are stacked to form a cup stack; then the cup stack is placed into a heated mold with the target cup 3D curved surface shape and heated and molded to form a cup body 100 with a 3D structure.
[0071] The key working mechanism is as follows: During the heat molding process, the elastic support 40 pre-attached to the first material layer is stretched and elastically strained along with the first material layer, thereby maintaining its attachment to the 3D convex curved surface corresponding to the cup body 100 after molding. Since the elastic support 40 itself is made of a heat-resistant polymer with high resilience and resistance to memory deformation, after the cup is heat-set, its stretched shape is constrained by the already-set first material layer, thus maintaining a stretched state and storing continuous elastic recovery stress at the corresponding parts of the cup body 100. Due to the continuous elastic strain or elastic strain tendency, the cup possesses a supporting shape even in a static state, actively and persistently providing upward support and inward support to the breasts when worn.
[0072] like Figures 1 to 6 As shown, this application also provides a bra including the aforementioned cup, wherein the cup body 100 includes at least an inner layer 10 conforming to one side of the breast and an outer layer 20 away from the breast. (See reference...) Figure 2 The inner layer 10 includes a lining fabric layer 11 and a lining cotton layer 12 stacked from the skin-contact side towards the outer garment, and the outer layer 20 includes an outer cotton layer 22 and an outer fabric layer 21 stacked from the skin-contact side towards the outer garment. An elastic support 40 is attached to the surface of the lining cotton layer 12 facing the outer layer 20. This type of bra can be any of the following: multi-size bras, sports bras, or regular bras, all of which benefit from the zoned elastic support and comfortable support provided by this invention. This cup is not only suitable for regular bras with standard sizes, effectively enhancing the support and lift of regular bras by adding the elastic support 40, but also, due to its excellent elastic adaptive properties, is suitable for bras used in postoperative recovery or for medical or orthopedic breast correction, providing support using elastic prestress rather than rigid materials to avoid compressing sensitive or unhealed tissues.
[0073] like Figures 1 to 5 As shown, this application also provides a garment that similarly includes the bra cups described above. (See reference...) Figure 3 Specifically, the garment can be a shapewear garment, in which the cup body 100 includes an inner layer 10 that conforms to one side of the breast and an outer layer 20 that is away from the breast. The inner layer 10 is a lining layer 11, and the outer layer 20 is an outer fabric layer 21. An elastic support 40 is attached to the surface of the lining layer 11 facing the outer fabric layer 21, thereby integrating the function of supporting and lifting the breasts in the shapewear.
[0074] More broadly, the technical solution of this application can be applied to any clothing that requires support for the breasts, providing support and lift to the wearer's breasts through the cup body 100. This covers a variety of clothing categories such as dresses, swimwear, sports tops, and formal wear. It should be noted that the cup placed inside the clothing can be composed of cotton layers and / or fabric layers, allowing for flexible design compatibility according to the design requirements of the clothing.

15. A method for manufacturing a bra cup with elastic support, characterized in that... Includes the following steps: S1. Provide a cup preform material, the cup preform material including a first material layer for forming an inner layer (10) that conforms to one side of the breast, and a second material layer for forming an outer layer (20) that is away from the side of the breast; S2. Apply gel-like polyurethane adhesive to the surface of the first material layer in a planar state according to a pre-set pattern. After heat curing, an elastic support (40) with a specific structure is formed. The first material layer and the elastic support (40) constitute a composite material layer. S3. The composite material layer and the second material layer are stacked to form a cup stack; and the cup stack is heated and molded to form a cup body (100) with a 3D structure. During the heating and molding process, the elastic support (40) stretches and elastically strains along with the first material layer and remains bonded to the 3D curved surface of the cup body (100). The elastic support (40) causes the cup body (100) to maintain elastic strain or elastic strain trend accordingly under its own elastic strain or elastic strain trend, thereby providing real-time elastic strain support to the cup body (100).
