Technical Field

[0001] This utility model relates to the field of underwear technology, and in particular to a women's wave-shaped seamless side-bone underwear. Background Technology

[0002] As one of the most basic and intimate garments in women's daily wear, underwear's main function is to cover and protect the private parts, absorb bodily secretions, reduce direct friction between outer clothing and skin, and to a certain extent meet the needs of comfort, aesthetics, and functionality.

[0003] Most existing women's underwear has a front and back panel splicing structure, and the sides are usually connected by stitches to form a straight side bone. However, in actual wear, the straight side bone is prone to arching outward under the action of body bending or hip tension. Utility Model Content

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a women's wave-shaped seamless side bone panty, which solves at least one of the above-mentioned technical problems. It has the advantage of preventing the side bones from arching outward, thus providing a better customer experience.

[0005] To achieve the above objectives, this utility model provides a women's wave-shaped seamless side-bone panty, comprising:

[0006] The underwear body includes a front panel and a back panel, which are connected by side bones, which are continuously curved in a wave shape from top to bottom.

[0007] When the user wears the underwear body, the wavy curves of the side bones prevent the side bones from arching outwards.

[0008] Optionally, the bottom of the front panel and the rear panel are formed with foot openings, the front and rear sides of which are continuously curved in a wave shape.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used to distinguish multiple parts or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0026] Please refer to Figures 1 to 2 This utility model provides a seamless women's wavy side-bone underwear, comprising: an underwear body 1, the underwear body 1 including a front panel 2 and a back panel 3, the front panel 2 and the back panel being connected by a side bone 4, the side bone 4 being a continuously curved wavy shape from top to bottom; when the user wears the underwear body 1, the curved portion of the wavy side bone 4 can prevent the side bone 4 from arching outwards; the wavy side bone 4 refers to the seam structure connecting the front panel 2 and the back panel 3, which can be achieved by hot pressing molding or elastic edge material, and its curvature matches the natural curve of the human hip. This structure disperses the lateral tension generated by hip movement through the wavy undulation. Specifically, the front panel 2 and the back panel 3 form a three-dimensional connection structure through the wavy side bone 4. When the human body is in a sitting or walking position, the curved portion of the wavy side bone 4 can deform and compensate with limb movements, avoiding single-point stress concentration. The alternating peaks and troughs of the wavy side bone 4 form multiple stress buffer nodes, effectively reducing the probability of the side bone 4 arching outwards.

[0027] In this embodiment, the bottom of the front panel 2 and the back panel 3 are formed with a foot opening 5, and the front and back sides of the foot opening 5 are continuously curved in a wave shape. The foot opening 5 refers to the edge structure connecting the bottom of the underwear with the front panel 2 and the back panel 3. The continuously curved wave shape refers to a non-straight edge composed of alternating undulating arc curves, which can be achieved by hot pressing molding process. The wave-shaped edge disperses the tension generated by leg movement.

[0028] Specifically, the foot openings 5 ​​at the bottom of the front panel 2 and the back panel 3 feature a wavy edge design that allows them to naturally conform to the curves of the human leg when worn. When the legs move, the curved part of the wavy foot opening 5 absorbs the lateral pulling force generated by the movement through deformation, preventing the straight edge from curling or leaving marks due to a single point of force.

[0029] In this embodiment, the side of the foot opening 5 closest to the female genitalia is arc-shaped. Furthermore, the arc shape refers to a curved shape with continuous curvature and uniform curvature. Specifically, it can be formed by rounded corner cutting or by hot pressing. The arc-shaped structure can avoid straight edges causing friction to sensitive areas.

[0030] Specifically, a curved edge is designed on the side of the instep 5 closest to the female genitalia, allowing this area to naturally conform to the curve of the groin area. When worn, the curved edge evenly distributes pressure, preventing marks caused by excessive local tension in traditional straight insteps 5, while also reducing edge curling due to body movement. The curvature of this curved edge can be adjusted according to ergonomic data to ensure complete coverage without pressure.

[0031] In this embodiment, the side of the leg opening 5 away from the female genitalia has a continuously curved, wavy shape. Further, the side of the leg opening 5 away from the female genitalia refers to the area located at the bottom of the underwear body 1 and in contact with the outer side of the leg. This area, through its wavy edge design, can adapt to the dynamic deformation during leg movement. The continuously curved, wavy shape refers to a non-linear contour composed of multiple alternating undulating arc curves.

[0032] Specifically, the outer edge of the foot opening 5 forms multiple natural curves through a wavy curve. When the leg extends or bends, the undulating structure of the wavy edge can undergo elastic deformation with the movement of the limb, so that the edge of the foot opening 5 forms multiple points of contact with the skin on the outer thigh.

[0033] In this embodiment, the front panel 2 and the rear panel 3 are bonded together by an adhesive. Further, the adhesive refers to the bonding component used to connect the front panel 2 and the rear panel 3. Specifically, it can be implemented using flexible adhesive materials such as hot melt adhesive. Its function is to replace the traditional suture connection method. The side bone 4 structure formed by the adhesive can maintain the continuity of the wavy contour and reduce the deformation of the side bone 4 caused by suture tension. When the user performs physical activities, the side bone 4 structure formed by the adhesive can bend naturally with the body curve, maintaining the integrity of the wavy contour, thereby preventing the side bone 4 from arching outward.

[0034] In this embodiment, a moisture-absorbing and antibacterial layer is provided on the inner side of the front panel 2, facing the female genitalia. Furthermore, this layer absorbs human secretions through the capillary action of the composite material, while the silver ions interfere with the metabolic activities of microbial cell membranes upon contact, thus maintaining a dry and clean contact surface through the dual effects of physical adsorption and chemical inhibition. This layer structure is confined to the genital area on the inner side of the front panel 2, avoiding material redundancy and precisely targeting areas prone to moisture.

[0035] In this embodiment, a non-invasive label 6 is provided on the front panel 2. Furthermore, the non-invasive label 6 is fixed to the edge area of ​​the front panel 2 by hot-melt bonding or surface etching, and its material has a similar softness and elasticity to the underwear fabric. During wear, the label does not produce a foreign body sensation or friction marks when in contact with the skin due to the absence of hard edges and seams. The label is positioned to avoid the central area of ​​the waistband, which is prone to wrinkling during body movement, and is preferably placed on a flat position on the side of the front panel 2 near the hip.

[0036] In this embodiment, a cushioning and shock-absorbing layer 7 is provided on the inner side of the rear panel 3, facing the user's buttocks. Further, the cushioning and shock-absorbing layer 7 refers to a material layer that conforms to the surface of the buttocks and has elastic deformation capabilities. Specifically, it can be made of foamed silicone or a honeycomb elastic fiber layer, absorbing the impact force generated by movement through the material's own compression and rebound characteristics. "Facing the user's buttocks" means that the coverage area of ​​the cushioning and shock-absorbing layer 7 perfectly matches the curve of the buttocks. This can be achieved through three-dimensional cutting or hot-pressing molding processes, ensuring that the cushioning layer is always in contact with the buttocks when the user is sitting or walking. When the user is sitting, the pressure on the buttocks is evenly distributed through the cushioning layer, avoiding excessive local pressure. During walking or running, the cushioning layer absorbs the impact energy generated by hip joint movement through elastic deformation, reducing friction and pressure on the buttocks.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the substance of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
