Description

Technical Field

[0001] This utility model relates to the field of clothing, and in particular to a type of underwear with a suspended crotch suitable for plus-size women. Background Technology

[0002] During menstruation, sanitary napkins, as the most commonly used menstrual care product for women, have evolved from a single-function product to a product with diversified designs. Initially, sanitary napkins had relatively simple sizes, mainly meeting daily absorption needs. However, as women's demands for comfort, safety, convenience, and environmental friendliness have continued to increase, the market has gradually segmented into products with different specifications.

[0003] As women pay more attention to menstrual hygiene, this has led to an increase in the selection of underwear, resulting in the emergence of menstrual underwear on the market. However, current menstrual underwear mainly focuses on leak-proof functions (such as a wider crotch and a seepage-proof layer), without addressing other issues.

[0004] 1. Friction at the edge of the sanitary napkin: The sides of the sanitary napkin cause repeated friction on the inner thighs, leading to redness, swelling, and broken skin;

[0005] 2. The side wing adhesive is not strong and it easily sticks to the upper thigh;

[0006] 3. Insufficient crotch length: The seams of traditional underwear are located at the back, making it easy for the front of the underwear to get dirty after the sanitary napkin is attached; and it can also cause discomfort due to friction when not menstruating.

[0007] 4. Inappropriate crotch width: It cannot fit most sanitary napkins. If it is too narrow, it will not stick to the sanitary napkin and will shift. If it is too wide, it will wrinkle.

[0008] In response, this utility model provides a suspended crotch underwear suitable for plus-size women. Summary of the Invention

[0009] The technical problem to be solved by this utility model embodiment is to provide a suspended crotch underwear suitable for plus-size women, addressing the various shortcomings of existing underwear.

[0010] To solve the above-mentioned technical problems, this utility model provides a suspended crotch underwear suitable for plus-size women, including: a front pant piece, a back pant piece, and a crotch; the crotch is connected to the front pant piece and the back pant piece through a front bob and a back bob, respectively;

[0011] The inner lining comprises an inner wave layer and a surface wave layer; the inner wave layer and the surface wave layer are partially sewn together; the area of ​​the inner wave layer is smaller than that of the surface wave layer.

[0012] Preferably, the inner wave layer has a first arc segment and a second arc segment at its edge; the first arc segment and the second arc segment are symmetrically distributed; the first arc segment and the second arc segment are separated from the surface wave layer; and the surface wave layer has a foot-shaped edge.

[0013] Preferably, the first arc segment is composed of arc AC, arc CD and arc DB; points A and B are the endpoints of the first arc segment and are connected to the surface wave layer; arc CD is parallel to the edge arc AB of the surface wave layer.

[0014] Preferably, the parallel distance between the arc CD and the edge arc AB of the surface wave layer is 0.4cm to 0.6cm.

[0015] Preferably, the endpoint of the front wave bone near the first arc segment is point O; the distance between point A and point O is 3cm to 4cm.

[0016] Preferably, the first arc segment and the second arc segment have the same structure.

[0017] Preferably, the arc AC and arc DB have the same structure; the length of arc AC is 0.8cm to 1.2cm.

[0018] Preferably, the narrowest part of the inner wave layer has a width of 5.5cm to 6.5cm.

[0019] Preferably, the inner wave layer is double-sided cotton-ammonia.

[0020] Preferably, when the suspended crotch underwear suitable for plus-size women is size M, the distance between the front wave bone and the back wave bone is 16cm to 17cm.

[0021] When the suspended crotch underwear suitable for plus-size women is size L or XL, the distance between the front and back ribs is 16.5cm to 17.5cm.

[0023] When the suspended crotch underwear suitable for plus-size women is size XXXL, the distance between the front and back ribs is 18.5cm to 19.5cm.

[0024] Implementing the embodiments of this utility model has the following beneficial effects:

[0025] (1) This utility model embodiment partially separates the inner wave layer from the outer wave layer and makes the inner wave layer smaller, so that the sanitary napkin can be easily placed between the inner wave layer and the outer wave layer, making it convenient and comfortable to wear. In addition, it can also solve problems such as edge friction of sanitary napkins and side wings easily sticking to the groin.

[0026] (2) This embodiment of the invention adjusts the distance between the front and back bodices so that the distance changes with the size of the underwear, thereby making the placement of the sanitary napkin more reasonable and convenient.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figure 1-2 This utility model provides a suspended crotch underwear suitable for plus-size women. The suspended crotch underwear includes a front panel 10, a back panel 20, and a crotch 30. The crotch 30 is connected to the front panel 10 and the back panel 20 via a front bob 40 and a back bob 50, respectively. The two ends of the front panel 10 and the back panel 20 are connected, together with the crotch 30, to form the suspended crotch underwear suitable for plus-size women.

[0034] The lining 30 includes an inner wave layer 310 and an outer wave layer 320. The inner wave layer 310 and the outer wave layer 320 are partially sewn together, leaving a gap at each of the left and right edges, allowing an item to pass between them. The area of ​​the inner wave layer 310 is smaller than that of the outer wave layer 320, specifically at the gaps.

[0035] In some embodiments, the inner wave layer 310 has a first arc segment 311 and a second arc segment 312 at its edge. The first arc segment 311 and the second arc segment 312 are symmetrically distributed. The first arc segment 311 and the second arc segment 312 are the edges of the gaps in the inner wave layer 310, and are separated from the surface wave layer 320.

[0036] In some embodiments, the first arc segment 311 is composed of arcs AC, CD, and DB. Points A and B are the endpoints of the first arc segment 311 and are connected to the surface wave layer 320. Arc CD is parallel to the edge arc AB of the surface wave layer 320. The parallel distance between arc CD and the edge arc AB of the surface wave layer 320 is 0.4cm to 0.6cm, preferably 0.5cm. Arcs AC and DB have the same structure. The length of arc AC is 0.8cm to 1.2cm, preferably 1cm. Furthermore, the first arc segment 311 and the second arc segment 312 have the same structure and are mirror images of each other. The suspended crotch underwear suitable for plus-size women, through the adjustment of the first arc segment 311 and the second arc segment 312, makes the sanitary napkin placed more smoothly between the inner wave layer 310 and the surface wave layer 320. Since both the first arc segment 311 and the second arc segment 312 are smooth curves, after adjusting the curvature of the first arc segment 311 and the second arc segment 312, the floating crotch underwear suitable for plus-size women will be more flat after wearing, so that there will be no strange feeling when wearing it due to the placement of sanitary napkins.

[0037] In some embodiments, the endpoint of the front wave 40 near the first arc segment is point O; the distance between point A and point O is 3cm to 4cm. Since the distance from the sanitary napkin fold to the side wing needs to be considered, the edge arc AB of the wave layer 320 is the opening length. This opening length should not be too long or too short. If it is too long, the underwear will roll up after the sanitary napkin is pasted, causing discomfort. If it is too short, insufficient for the side wing length of the sanitary napkin, the operation of flipping and pasting the side wing will be very difficult. Therefore, the opening length is set by adjusting the distance between point A and point O, thereby simplifying the placement of the sanitary napkin.

[0038] In some embodiments, the crotch size of the suspended crotch underwear suitable for plus-size women is modified. When the suspended crotch underwear suitable for plus-size women is size M, the distance from the front wave to the back wave is 16cm to 17cm. When the suspended crotch underwear suitable for plus-size women is size L or XL, the distance from the front wave to the back wave is 16.5cm to 17.5cm. When the suspended crotch underwear suitable for plus-size women is size XXL, the distance from the front wave to the back wave is 17.5cm to 18.5cm. When the suspended crotch underwear suitable for plus-size women is size XXXL, the distance from the front wave to the back wave is 18.5cm to 19.5cm. The narrowest width of the inner wave layer 310 is 5.5cm to 6.5cm, preferably 6cm. The narrowest width of the outer wave layer 312 is 6.5cm to 7.5cm, preferably 7cm. The aforementioned floating crotch underwear, designed for plus-size women, addresses the issues of insufficient crotch length and unreasonable crotch width by modifying the crotch size 30.

[0039] In some embodiments, the edge of the outer wave layer 320 is provided with a foot flap 321. Therefore, when the sanitary napkin is placed, the side flaps of the sanitary napkin, after being glued, are located between the inner wave layer 310 and the outer wave layer 320. The bottom of the sanitary napkin does not contact the user's skin. Even if the sanitary napkin is not very adhesive, it will not shift significantly because it is sandwiched between the inner wave layer 310 and the outer wave layer 320, thus solving problems such as edge friction and the side flaps easily sticking to the groin.

[0040] In some embodiments, the inner lining layer 310 is double-sided cotton-ammonia blend. Double-sided cotton-ammonia blend has the characteristics of not curling or unraveling after cutting, and can be directly and freely cut without hemming. The inner lining layer 310 has no impact on the sewing process, and the double-sided cotton-ammonia blend will not affect the hygiene and health of the intimate area.

[0041] When using the plus-size floating crotch underwear during menstruation, first align the folded edge of the sanitary napkin with the front wave 40 and place it on top of the crotch 30. The user then inserts their hand through the gap between the inner wave layer 310 and the outer wave layer 320 to increase the space between the two layers for easier attachment of the side wings. Next, fold the sanitary napkin side wings over and attach them to the bottom of the inner wave layer 310 to complete the attachment. At this point, the bottom of the sanitary napkin is covered by the outer wave layer 320, and the side cuffs 321 isolate it from skin contact, preventing discomfort during body movement. Furthermore, outside of menstruation, the plus-size floating crotch underwear feels the same as regular underwear and will not cause discomfort.

[0042] In summary, this embodiment of the invention partially separates the inner wave layer 310 from the outer wave layer 320, and makes the inner wave layer 310 smaller, thus allowing the sanitary napkin to be easily placed between the inner wave layer 310 and the outer wave layer 320, achieving convenient and comfortable wear. Furthermore, it solves problems such as edge friction and the side wings easily sticking to the inner thigh. Moreover, this embodiment of the invention adjusts the distance between the front wave bone 40 and the back wave bone 50, allowing the distance to change with the size of the underwear, thereby making the placement of the sanitary napkin more reasonable and convenient. During non-menstrual periods, the front wave bone 40 and the back wave bone 50 also avoid sensitive areas, ensuring wearing comfort.

[0043] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.
