Description

Technical Field

[0001] The present invention relates to the technical field of clothing, in particular to the field of women's underwear such as bras, and in particular to a flexible steel ring and underwear having the same. Background Art

[0002] The steel rings of existing bras and other women's underwear are generally made of hard metal materials, and a specific and stable steel ring shape is obtained through mechanical processing methods such as hot pressing, extrusion, and stamping. The steel ring is then fixed to the corresponding position of the bra and other women's underwear, and the steel ring is used to achieve the functions of fixing and shaping. Because traditional steel rings are made of hard metal materials, they are very hard and will exert great pressure on the human body after wearing, resulting in poor comfort. In severe cases, they may even cause irreversible invisible damage to the human body.

[0003] In order to avoid the discomfort caused by traditional hard metal underwires, the applicant developed underwire-free underwear through early research and filed relevant patent applications, such as patent applications with publication (notice) numbers CN105054333A and CN205409709U. This type of underwire-free underwear has adjusted the structure of the underwear. Specifically, vertical support bones are set on the side wings near the cup body, and inclined support bones are set at the lower ribs; elastic edges that penetrate and connect the lower ribs and the side wings are set at the bottom of the lower ribs and the side wings. Compared with bras with underwires, the adjusted underwear is more comfortable to wear, has no pressure on the breasts, can ensure smooth blood flow, and has many benefits for breast health. However, it was found during use that although this underwire-free underwear has a good effect of gathering the breasts and reducing the pressure on the breasts, the breast shaping and support effects of thin cups, lace materials and single-layer cloth structure underwear are not ideal, and the underwear is easy to deform after long-term wear. In addition, other underwire-free bras that have appeared on the market in recent years also have problems in terms of craftsmanship and application, such as lack of support, single structure and shape, thick base, and complex craftsmanship.

[0004] Therefore, providing a flexible underwire and underwear having the same, which has a simple preparation process, good shaping and supporting effects, low breast pressure, comfortable wearing, and not easy to deform, is one of the technical problems that need to be urgently solved by technicians in this field. Summary of the invention

[0005] In view of this, the present invention aims to propose a flexible underwire and underwear having the same, so as to solve the technical problems of existing underwear in shaping and supporting the chest, poor versatility, strong pressure on the breasts, discomfort when wearing, easy deformation and difficult preparation.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A flexible steel ring, comprising a first outer layer material and a second outer layer material arranged relatively on the outer surfaces of both sides of the flexible steel ring, at least one inner layer material is arranged between the first outer layer material and the second outer layer material, and the first outer layer material, the second outer layer material and the inner layer material are all non-metallic flexible materials.

[0008] Furthermore, a dielectric material is disposed between the first outer layer material and the second outer layer material, and the dielectric material is located in a gap formed by the first outer layer material, the inner layer material and the second outer layer material being arranged in layers in sequence.

[0009] Furthermore, the dielectric material is a non-metallic flexible material.

[0010] Furthermore, the flexible underwire includes at least two different non-metallic flexible materials.

[0028] In order to make the technical means, objectives and effects of the present invention easy to understand, the embodiments of the present invention are described in detail below with reference to specific drawings.

[0029] It should be noted that all the terms used in the present invention to indicate directionality and position, such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "inside", "outside", "top", "lower", "lateral", "longitudinal", "center", etc., are only used to explain the relative positional relationship and connection status between the components in a certain state, and are only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0030] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0031] Specifically, Figure 1-7 As shown, a flexible steel ring, the flexible steel ring 5 includes a first outer layer material 1 and a second outer layer material 2 which are relatively arranged on the outer surfaces of both sides of the flexible steel ring 5, at least one inner layer material 3 is arranged between the first outer layer material 1 and the second outer layer material 2, and the first outer layer material 1, the second outer layer material 2 and the inner layer material 3 are all non-metallic flexible materials.

[0032] Preferably, the first outer layer material 1 is cloth or cloth-applied sponge, the second outer layer material 2 is cloth or cloth-applied sponge, and the inner layer material 3 is one of cloth, sponge or PVC.

[0033] Furthermore, the flexible steel ring 5 includes at least two different non-metallic flexible materials.

[0034] The flexible steel ring 5 uses non-metallic flexible materials instead of traditional alloy metal materials. Through one or more processing techniques such as bonding, sewing, and hot plastic pressing, each layer of flexible materials can be fixed together according to the designed shape and structure to achieve the designed shape of the flexible steel ring 5. The flexible steel ring 5 adopts a structure in which multiple layers of non-metallic flexible materials are superimposed. On the one hand, it can have a higher strength to achieve the fixing and shaping functions of the traditional steel ring; on the other hand, it can have a certain flexibility. When the flexible steel ring 5 is fixed on underwear such as a bra, it will not cause invisible damage to the human body by squeezing and pressing the chest when worn, which greatly improves the wearing comfort of the flexible steel ring 5 and the underwear products having it. In addition, the flexible steel ring 5 realizes the process requirements of the steel ring being carable, pressable, and moldable without changing the process, structure, and product performance of underwear such as traditional bras, making the flexible steel ring 5 easier to prepare than the traditional metal steel ring. Furthermore, the structural design of the flexible steel ring 5 with multiple layers of non-metallic flexible materials superimposed makes the flexible steel ring 5 extremely resistant to deformation, so that the underwear having it can be used for a long time and is not easy to deform.

[0035] Furthermore, a dielectric material 4 is provided between the first outer layer material 1 and the second outer layer material 2. The dielectric material 4 is located in a gap formed by the first outer layer material 1, the inner layer material 3 and the second outer layer material 2 being arranged in layers in sequence.

[0036] Furthermore, the dielectric material 4 is a non-metallic flexible material.

[0037] Preferably, the dielectric material 4 is one of glue, PUR or PVC. The dielectric material 4 mainly serves to increase firmness and prevent deformation.

[0038] Preferably, 1 to 10 layers of inner layer material 3 are arranged between the first outer layer material 1 and the second outer layer material 2 .

[0039] More preferably, three layers of inner layer material 3 are arranged between the first outer layer material 1 and the second outer layer material 2 .

[0040] Furthermore, the thickness of each inner layer material 3 may be the same or different.

[0041] Furthermore, the first outer layer material 1, the inner layer material 3, the medium material 4 and the second outer layer material 2 are combined together by heating and pressurizing.

[0042] Specific: First follow Figures 1-2 As shown, the first outer layer material 1, the inner layer material 3, the medium material 4 and the second outer layer material 2 are stacked together, and then the stacked materials are placed in a special machine, mold, or other tooling container, and the materials are heated and pressurized. Under the conditions of external force and heat, the materials undergo changes in physical properties in the special machine, mold, or other tooling container, such as becoming soft and sticky, and finally form a flexible steel ring 5 with the shape and structure required by the design.

[0043] Furthermore, Figure 3 and Figure 4 As shown, the flexible steel ring 5 is an arc-shaped strip structure, and the long axis of the flexible steel ring 5 is taken from one end of the flexible steel ring 5 to the other end along the geometric center line of the flexible steel ring 5. The flexible steel ring 5 includes a first flexible portion 51 and a second flexible portion 52. In a cross section perpendicular to the long axis of the flexible steel ring 5, the first flexible portion 51 is located on both sides of the second flexible portion 52, and the thickness of the first flexible portion 51 is less than the thickness of the second flexible portion 52. Preferably, the first flexible portion 51 and the second flexible portion 52 are integrally formed, and more preferably, the first flexible portion 51 and the second flexible portion 52 are smoothly transitionally connected.

[0044] Furthermore, the thickness of one end or both ends of the flexible steel ring 5 is smaller than the thickness of the second flexible portion 52. The density of one end or both ends of the flexible steel ring 5 is greater than the density of the second flexible portion 52.

[0045] Specifically, when preparing the flexible steel ring 5, first, the machine, mold, or other tooling container used to accommodate the flexible steel ring 5 needs to be designed into a shape corresponding to the flexible steel ring 5. When the material is heated and pressurized, the first outer layer material 1, the inner layer material 3, the medium material 4, and the second outer layer material 2 located in the first flexible part 51 will be compressed to a greater extent, so that the material density of the first flexible part 51 is greater than the density of the second flexible part 52, that is, on the cross section perpendicular to the long axis of the flexible steel ring 5, high-density areas on both side edges and low-density areas in the middle are formed by hot pressing the flexible material, which is beneficial to improving the strength of the flexible steel ring 5, so that it can further replace the traditional steel ring to realize its support and shaping functions.

[0046] Furthermore, the area of ​​the first flexible portion 51 complies with conventional processing techniques, size standards and structural requirements for subsequent fixing to underwear such as a bra, such as sewing and bonding.

[0047] Furthermore, the second flexible portion 52 has a certain thickness, elasticity and toughness, so that the first flexible portion 51 can cooperate with the second flexible portion 52, so that the flexible steel ring 5 has both good elasticity and flexibility and high strength, and jointly realizes functions related to the strength of the flexible steel ring 5.

[0048] Furthermore, the overall appearance of the flexible underwire 5 meets the design requirements and ergonomic requirements, so as to enhance the wearing comfort and aesthetics of underwear products such as bras with the flexible underwire 5 .

[0049] As some embodiments of the present invention, the present invention further provides a bra having a cup 6 , wherein the flexible underwire 5 is located at the lower edge of the cup 6 .

[0050] Furthermore, a thickness reduction area is provided at the lower edge of the cup 6, and the flexible underwire 5 is arranged in the thickness reduction area.

[0051] Furthermore, the position and process of fixing the flexible steel ring 5 on underwear products such as bras are the same as those of traditional metal steel rings, which will not be repeated here.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
