[0002] In the modern clothing system, boxer shorts have become a basic item in women's daily wardrobes due to their simple design, comfortable wearing experience, and ease of pairing with various bottoms.
[0003] During menstruation, the user needs to attach the sanitary napkin to the inside of the underwear, and then fold the wings back to secure them to the fabric on the inside of the thighs to keep the sanitary napkin in place and prevent it from shifting.
[0004] However, the wings of sanitary napkins are constantly pressed against the inner thighs, which greatly affects the user's experience. Moreover, prolonged friction can easily cause skin itching, redness, swelling, itching, or even allergic reactions. Utility Model Content
[0005] To address the aforementioned shortcomings, this utility model proposes a women's boxer shorts where the sanitary napkin's wings are attached to the side of the panty away from the body. This solves the problem of the sanitary napkin's wings always being tightly pressed against the inner thigh when wearing traditional boxer shorts, resulting in a poor wearing experience and improving the convenience and comfort of use.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A type of women's boxer shorts includes a pant body, a high-waisted panel, and a gusset. The top of the pant body is connected to the high-waisted panel, which is used to wrap around the waist. The pant body includes a front panel, a back panel, and side panels. The left and right sides of the front panel and the back panel are connected by the side panels.
[0008] The front piece includes a triangular section and a leg guard section. The left and right sides of the triangular section are connected to the leg guard section. The leg guard section, the side piece on the same side, and the back piece are sewn together to form a trouser leg. The trouser leg is used to cover the legs and hips on both sides of the abdomen. The back piece is used to cover the buttocks. The triangular section is used to cover the abdomen and crotch.
[0009] The baffle is provided on the inner side of the triangular part. The front end of the baffle is located at the seam between the high waist piece and the triangular part, and the end of the baffle is located at the seam between the triangular part and the back piece. The baffle is used for attaching the sanitary napkin to the pant body. The space between the baffle and the triangular part forms a storage space for storing the wings of the sanitary napkin.
[0010] The baffle comprises, from front to back, a first widened section, a middle narrowed section, and a last widened section. The widened section is provided with a vertical first suture line, which is used to sew the triangular portion to the middle part of the first widened section. The middle narrowed section and the triangular portion form a storage space. The last widened section is provided with a vertical second suture line, which is used to sew the triangular portion to the middle part of the last widened section.
[0011] The baffle is made of pure cotton, and the triangular part is made of breathable mesh fabric.
[0012] The length of the side panel is less than the length of the leg guard, and an inwardly recessed notch is formed on the side of the trouser leg away from the triangular part.
[0013] Both the back panel and the leg guard have rounded corners near the notch, and the back panel and the side panel transition smoothly.
[0014] The edges of the trouser legs are sewn with a folded edge, which has a double-layer structure.
[0015] The seams of the trousers, high-waisted panels, and gusset panels are all stitched using a four-needle, six-thread technique.
[0016] The technical solution of this utility model can include the following beneficial effects:
[0017] 1. The backing plate provides a clear and defined application area for the sanitary napkin. When attaching the sanitary napkin, place the main body of the napkin on the side of the backing plate closest to the body.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] The following is combined Figures 1 to 3 This describes a women's boxer shorts according to an embodiment of the present utility model.
[0028] A type of women's boxer shorts includes a pant body 1, a high-waisted panel 2, and a gusset 3. The top of the pant body 1 is connected to the high-waisted panel 2, which is used to wrap around the waist. The pant body 1 includes a front panel 11, a back panel 12, and side panels 13. The left and right sides of the front panel 11 and the back panel 12 are connected by the side panels 13.
[0029] The front piece 11 includes a triangular portion 111 and a leg guard portion 112. The left and right sides of the triangular portion 111 are connected to the leg guard portion 112. The leg guard portion 112, the side piece 13 on the same side, and the back piece 12 are sewn together to form a trouser leg. The trouser leg is used to cover the legs and hips on both sides of the abdomen. The back piece 12 is used to cover the buttocks. The triangular portion 111 is used to cover the abdomen and crotch.
[0030] The baffle 3 is provided on the inner side of the triangular part 111. The front end of the baffle 3 is located at the seam between the high waist piece 2 and the triangular part 111, and the end of the baffle 3 is located at the seam between the triangular part 111 and the back piece 12. The baffle 3 is used for attaching the sanitary napkin to the pant body 1. The space between the baffle 3 and the triangular part 111 forms a storage space for storing the wings of the sanitary napkin.
[0031] The pant body 1 is composed of a front panel 11, a back panel 12, and side panels 13. This segmented design allows the pant body to collectively withstand body movement and external pressure. Compared with the traditional one-piece structure, the segmented structure distributes stress more evenly when subjected to external forces, making it less prone to local deformation or damage. This improves the overall strength and stability of the pant body 1 and extends the lifespan of the boxer shorts.
[0032] The front panel 11 is further subdivided into a triangle section 111 and a leg guard section 112. This subdivision design enhances the support of the front panel 11 for the abdomen and crotch. The triangle section 111 provides stable support for the abdomen and crotch, while the leg guard section 112 provides good wrapping and support for the legs and hips. This enhanced local support helps maintain the shape and structural stability of the trousers 1, reducing deformation or damage caused by excessive local stress.
[0033] The cover 3 provides a clear and defined working area for the sanitary napkin. When attaching the sanitary napkin, place the main body of the napkin on the side of the cover 3 closest to the body. The cover 3 allows users to quickly and accurately find the attachment position, avoiding problems such as crooked or insecure attachment caused by blindly searching for the attachment position, greatly improving the efficiency and success rate of attachment.
[0034] Then fold the sanitary napkin's wings and attach them to the side of the pad 3 away from the body. The inner side of the pad 3 provides space for attaching the wings, allowing the user to easily fold the wings according to the outline of the pad 3 and accurately attach them to the designated position, making the entire attachment process smoother and more convenient.
[0035] At this time, the main body and wings of the sanitary napkin can fully contact the two sides of the baffle 3, increasing the adhesive area and effectively preventing the sanitary napkin from shifting due to body movement, friction, etc. during use, ensuring that the sanitary napkin always stays in the correct position.
[0036] Moreover, the sanitary napkin's wings are attached to the side of the pad 3 away from the body, solving the problem that when wearing traditional boxer shorts, the sanitary napkin's wings are always close to the inner thigh, resulting in a poor wearing experience, thus improving the convenience and comfort of use.
[0037] The baffle 3 comprises, from front to back, a first widened section 31, a middle narrowed section 32, and a last widened section 33. The first widened section 31 is provided with a vertical first suture line 311, which is used to sew the triangular section 111 and the middle part of the first widened section 31. The middle narrowed section 32 and the triangular section 111 form a storage space. The last widened section 33 is provided with a vertical second suture line 331, which is used to sew the triangular section 111 and the middle part of the last widened section 33.
[0038] By setting the first widened section 31, a larger contact area is formed between the first end of the gusset 3 and the seam between the high waist piece 2 and the front piece 11, significantly enhancing the gusset 3's anti-sagging ability. The middle narrowed section 32 conforms to the curve of the thigh root triangle area, preventing the gusset 3 from being too wide and causing skin friction. The end of the final widened section 33 is set at the seam between the front piece 11 and the back piece 12, ensuring that the gusset 3 is tightly integrated with the main structure of the boxer shorts.
[0039] Furthermore, the baffle 3 is also provided with a first stitch 311 and a second stitch 331. The first stitch 311 can sew the middle portion of the first widened portion 31 to the triangular portion 111. The second stitch 331 can sew the middle portion of the end widened portion 33 to the triangular portion 111. Therefore, the first stitch 311 and the second stitch 331 can fix the baffle 3 to the inside of the triangular portion 111, effectively preventing the baffle 3 from shifting or falling off due to washing or friction.
[0040] Furthermore, the narrow section 32 in the middle is not sewn, which ensures that the wings of the sanitary napkin can be attached to the side of the baffle 3 near the triangular part 111, thereby storing the wings and preventing the wings from rubbing against the skin, which could lead to redness and allergies.
[0041] The baffle 3 is made of pure cotton, and the triangular part 111 is made of breathable mesh fabric.
[0042] Pure cotton fibers naturally possess antibacterial properties, effectively inhibiting bacterial growth and reducing the risk of odor or infection caused by bacterial proliferation. This makes it especially suitable for women during menstruation and other special periods, providing a healthier wearing environment. Breathable mesh fabric accelerates sweat evaporation, reducing dampness in the groin area and inhibiting bacterial growth at its source.
[0043] The length of the side panel 13 is less than the length of the leg guard 112, and an inwardly recessed notch is formed on the side of the trouser leg away from the triangular portion 111.
[0044] Traditional boxer shorts typically have a continuous straight or slightly flared leg design, with the fabric deforming relatively evenly in both the horizontal and vertical directions, making it easy to form a stable curl.
[0045] The pant body 1 has an inwardly recessed notch, which makes the pant leg lack a continuous support structure in the vertical direction. When the pant leg attempts to roll up, the fabric at the notch will have difficulty forming a stable curl shape due to the lack of lateral support, thereby reducing the occurrence of pant leg roll-up and improving the user's wearing experience.
[0046] Both the rear panel 12 and the leg guard 112 have rounded corners near the notch, and the rear panel 12 and the side panel 13 transition smoothly.
[0047] The back piece 12 and the leg guard 112 are rounded near the notch to avoid friction between the right-angled edges of the back piece 12 and the leg guard 112 and the skin, reduce marks or discomfort caused by the pressure of the fabric edges during long-term wear, and further improve the user's wearing experience.
[0048] The edges of the trouser legs are sewn with a folded edge 4, which has a double-layer structure.
[0049] Folding the edge (4) refers to folding the edge of the fabric inward or outward and then sewing it to form a double or multi-layer structure. The double-layer structure created by folding the edge (4) makes the edge of the trousers thicker, requiring greater external force when deformed, significantly increasing the difficulty of rolling up the hem, and further reducing the occurrence of rolled-up trouser hems.
[0050] The seams of the trouser body 1, high waist panel 2, and gusset panel 3 are all stitched using a four-needle, six-thread technique.
[0051] The four-needle, six-thread technique uses four stitches and two reinforcing threads to form a three-dimensional mesh structure, effectively enhancing the tensile strength of the seams between the trouser body 1, the high-waisted panel 2, and the gusset panel 3. Furthermore, the four-needle, six-thread technique reduces the stitch width by 50% compared to traditional methods, with a seam thickness of only 0.5-1mm, resulting in almost no bumps when worn against the skin, making it especially suitable for sensitive skin or situations requiring close-fitting clothing.
[0052] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
