Description

Technical Field

[0001] This utility model belongs to the field of underwear technology, specifically relating to an invisible underwear with an anti-embarrassment crotch structure. Background Technology

[0002] In the modern clothing market, as living standards improve, consumers are placing higher demands on the comfort and functionality of intimate apparel. Underwear, as an indispensable part of women's daily attire, primarily functions to protect women's private parts and help maintain personal hygiene, while also requiring high comfort and elasticity. For example, Chinese Patent CN200944830Y discloses a type of sanitary underwear that incorporates antibacterial non-woven fabric between the outer and inner layers, providing breathability, moisture absorption, sterilization, and odor removal during wear.

[0003] However, besides being breathable, moisture-wicking, antibacterial, and odor-eliminating, underwear also needs to conceal a woman's natural curves and prevent embarrassing lines from being visible during exercise, thus avoiding highlighting the shape of a woman's toe. Therefore, anti-embarrassment underwear has emerged on the market. These underwear typically use a one-piece molded, thickened sponge material as its core functional component. By incorporating a dense sponge layer in the crotch area, they conceal the lines of a woman's natural curves, providing users with a more private and confident wearing experience.

[0004] However, these anti-embarrassment underwear have revealed a series of problems in actual wear. First, due to the thick sponge material, the edges of the underwear tend to form a noticeable outline, especially under tight-fitting or thin outer clothing. This outline is still visible, affecting the product's invisible and seamless effect and potentially causing embarrassment for the wearer. Second, the dense internal structure of the sponge results in poor breathability, failing to meet the heat dissipation needs during physical activity and easily causing a stuffy feeling. When the body sweats, although the sponge can quickly absorb sweat, the poor breathability prevents the sweat from evaporating quickly, causing the crotch area to remain damp for a long time. This reduces wearing comfort and may exacerbate bacterial growth, posing a potential threat to women's intimate health. Summary of the Invention

[0005] To address the problems in related technologies, this utility model proposes an invisible underwear with an anti-embarrassment crotch structure to overcome the aforementioned technical issues in existing technologies. This utility model features a crotch area covered by a front panel, equipped with a unique inner lining structure to effectively prevent embarrassing lines at the crotch. The thickness of the crotch structure is significantly less than the thickness of the sponge in existing technologies, ensuring both anti-embarrassment performance and breathability and moisture absorption, helping to keep the intimate area dry and comfortable.

[0038] Example 1

[0039] like Figure 1-7 As shown, this embodiment provides an invisible underwear with an anti-embarrassment crotch structure, including an underwear body. The underwear body includes a front panel 1 and a back panel 2 connected in front and back. The front panel 1 has a crotch 11 covering the user's private parts. The crotch 11 includes an inner lining structure 3 located inside the front panel 1. The inner lining structure 3 is used to support the crotch 11 to prevent embarrassing lines from being exposed at the crotch 11.

[0040] The inner lining structure 3 includes a skin-adhering layer 31, a control layer 33, and a protective layer 34; after the skin-adhering layer 31, the control layer 33, the protective layer 34, and the front panel 1 are stacked in sequence, a crotch structure 4 with a stepped edge thickness is formed.

[0041] The control layer 33 is stacked on the side of the protective layer 34 facing the human body, and its area is smaller than that of the protective layer 34, with its edges recessed to form a first step 51; the protective layer 34 has an area smaller than that of the skin-adhesive layer 31, and its edges recessed to form a second step 52; the skin-adhesive layer 31 is stacked on the side of the control layer 33 facing the human body, and its area is smaller than that of the front panel 1, with its edges recessed to form a third step 53.

[0042] The edges of the skin-adhesive layer 31 are respectively bonded and connected to the edges of the protective layer 34 and the front panel 1 to form a continuous stepped edge sealing structure 5.

[0043] Firstly, this embodiment features a crotch 11 covering the user's private area via a front panel 1. This crotch 11 is also equipped with a unique inner lining structure 3, effectively preventing any embarrassing seams that may occur at the crotch 11. This design fully considers the user's privacy needs during wear, ensuring that the crotch 11 remains flat and invisible under any activity, greatly enhancing the user's confidence and comfort.

[0044] Furthermore, the lining structure 3 in this embodiment employs a three-layer overlapping design: a skin-contact layer 31, a control layer 33, and a protective layer 34. Each layer's edges are tapered inwards to form a stepped change, ultimately fitting snugly against the front panel 1 to form a continuous stepped edge sealing structure 5. This not only enhances the support of the crotch area 11 but also makes the transition of the underwear's edge more natural and smooth, avoiding the abruptness that may occur with traditional underwear edges, further improving wearing comfort and aesthetics.

[0045] In addition, the crotch structure 4 has a multi-layered design, and its thickness is significantly less than that of the sponge in the prior art. While ensuring the anti-embarrassment performance, it also fully considers the breathability and moisture absorption of the invisible underwear, which helps to keep the private parts dry and comfortable, reduce bacterial growth, and thus help maintain personal hygiene and health.

[0046] Specifically, one side of the control layer 33 is fully bonded to the protective layer 34; the control layer 33 includes inelastic mesh or the control layer 33 is made of inelastic mesh.

[0047] The control layer 33 not only controls the force but also ensures that the anti-embarrassment structure is not stretched during wearing and movement, maintaining its flatness and thus effectively preventing embarrassing situations from occurring.

[0048] Specifically, the thickness of the control layer 33 ranges from 1.0mm to 2.0mm, maintaining the thinness of the bottom structure 4.

[0049] Specifically, the distance between the first step 51 and the second step 52 is smaller than the distance between the second step 52 and the third step 53; the edge thickness of the bottom structure 4 decreases in a stepped manner from the inside to the outside.

[0050] The stepped spacing design creates a reasonable transition area between the skin-contact layer 31, the control layer 33, and the protective layer 34 in the crotch structure 4. The smaller spacing between the first step 51 and the second step 52 helps reduce friction between the layers, minimizing the feeling of foreign objects when wearing them, thereby improving wearing comfort. At the same time, the stepped reduction in edge thickness from the inside out makes the edges of the underwear smoother, reducing pressure on the skin and further enhancing wearing comfort.

[0051] Specifically, the bottom of the front panel 1 is connected to the bottom of the back panel 2 to form a first connecting part 6; when the underwear body is laid flat, the first connecting part 6 is located on the back side of the underwear body; the bottom of the skin-contact layer 31 extends away from the back panel 2 until it overlaps with the first connecting part 6.

[0052] The rear-mounted first connecting part 6 helps to avoid friction on the human body's private parts and improves comfort.

[0053] Specifically, the skin-adhesive layer 31 includes an upper edge 311 and a lower edge 312; the upper edge 311 extends toward the waistband 8, and the lower edge 312 extends toward the first connecting portion 6; the left and right sides of the lining structure 3 gradually narrow from the upper edge 311 to the lower edge 312.

[0054] Specifically, the upper edge line 311 and the lower edge line 312 are both arc-shaped, wavy, or straight; this embodiment does not limit the shape of the upper edge line 311 and the lower edge line 312, and they can be any common shape other than the above-mentioned shapes;

[0055] More specifically, the shapes of the skin-adhesive layer 31, control layer 33, and protective layer 34 include inverted trapezoids, inverted triangles, or fan shapes; this embodiment does not limit the shapes of the skin-adhesive layer 31, control layer 33, and protective layer 34, and they can be any common shapes other than those mentioned above.

[0056] Specifically, the two sides of the front panel 1 are respectively connected to the two sides of the back panel 2 by means of bonding and / or sewing to form a second connecting part 7; when the underwear body is laid flat, the second connecting part 7 is located on the front side of the underwear body;

[0057] It should be noted that, in addition to bonding and sewing, other common connection methods also achieve the same technical effect;

[0058] In this embodiment, a second connecting portion 7 is formed by connecting the two sides of the front panel 1 to the two sides of the back panel 2, and it is designed to be located on the front side when the underwear body is laid flat. Compared with the side seam position of traditional underwear, this achieves a forward shift effect. This design significantly enhances the support of the front panel of the underwear to the sides, effectively strengthening the overall stability of the underwear. When wearing it, even during vigorous activities, the middle of the front panel 1 is less likely to slip down, thus maintaining the stability and comfort of the invisible underwear.

[0059] Example 2

[0060] like Figure 8-9 As shown, this embodiment also provides another type of invisible underwear with an anti-embarrassment crotch structure. Features not explained in this embodiment can be explained using the methods in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is:

[0061] The inner lining structure 3 also includes a padding layer 32 disposed between the skin-contact layer 31 and the control layer 33. One side of the padding layer 32 is fully connected to the control layer 33, while the other side is not connected to the skin-contact layer 31. The padding layer 32 is used to elevate the middle of the crotch 11, further filling the recessed area of ​​the user's private parts, visually presenting a smooth outer surface effect, and further avoiding the appearance of embarrassing lines.

[0062] Specifically, the thickness of the middle part of the crotch structure 4 is 3.0-18.0 mm;

[0063] More specifically, when the padding height 32 is not provided, the thickness of the middle part of the crotch structure 4 is 3.0-7.0mm; when the padding height 32 is provided, the thickness of the middle part of the crotch structure 4 is 8.0-12.0mm; the above thickness range ensures that the invisible underwear has sufficient support and avoids the discomfort caused by excessive thickness.

[0064] The edge transition thickness of the crotch structure 4 is 0.1-8.0mm, which makes the edge of the crotch structure 4 smoother. At the same time, the smooth transition also helps to improve the fit of the invisible underwear to the body, making the underwear less likely to shift during activities.

[0065] Specifically, the shape and size of the padding layer 32 are the same as those of the control layer 33.

[0066] Specifically, the padding layer 32 and the protective layer 34 are both made of sandwich structure material with a thickness range of 1.0mm-5.0mm. In this embodiment, 1.0mm is preferred to maintain the thinness of the inner lining structure 3 and further prevent the user from forming an obvious outline in the crotch 11 when wearing the underwear, thus achieving an invisible and seamless effect.

[0067] The sandwich structure material has excellent breathability and elasticity, wherein the elasticity of the sandwich structure material is greater than that of the non-elastic mesh.

[0068] In this embodiment, the sandwich structure material is the name of a fabric, scientifically known as polymer synthetic fiber yarn, as detailed below:

[0069] The main raw material of sandwich structure materials is high-molecular synthetic fiber yarn, which is refined from petroleum. Sandwich structure materials are usually woven by warp knitting machines and have three layers: top, middle, and bottom. The surface is usually a mesh design, the middle layer is MOLO yarn connecting the surface and the bottom, and the bottom is a densely woven flat surface.

[0070] The sandwich-structured material's three-dimensional mesh structure gives it excellent breathability and moderate conditioning capabilities, earning it the reputation of a "breathable mesh." This three-dimensional mesh structure promotes smooth airflow and ensures a dry and comfortable surface. Furthermore, this three-dimensional mesh structure can stretch under external force and return to its original shape after the force is removed, providing excellent cushioning protection. In addition, the lightweight texture of the three-dimensional mesh structure makes it suitable for hand washing, machine washing, and dry cleaning, facilitating cleaning and air drying.

[0071] The sandwich structure material is treated with anti-mildew and antibacterial agents, which can effectively inhibit bacterial growth and thus maintain hygienic conditions.

[0072] The sandwich structure material is also made of warp knitting, which makes it strong and durable and able to withstand high-intensity tension and tearing.

[0073] In this embodiment 2, it should be noted that some users have a habit of shaving their pubic hair, which can make the indentation in the pubic area more noticeable. Therefore, an additional padding layer 32 is added to further fill the indented area. Users who do not shave their pubic hair can simply use the invisible underwear in embodiment 1. If these users use the invisible underwear in embodiment 2, although the padding layer 32 can fill the indentation, its outer surface will still appear unnatural. In addition, the indentation area of ​​each person's pubic area will vary slightly, and users can choose suitable invisible underwear with an anti-embarrassment crotch structure according to their own needs.

[0074] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. 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 utility model.
