Description

Technical Field

[0001] This utility model relates to the field of hygiene products technology, and more specifically to a leak-proof pad with protective wings. Background Technology

[0002] During menstruation, women experience the physiological phenomenon of uterine lining shedding, resulting in the discharge of blood clots, secretions, and menstrual blood each month. Sanitary pads are an indispensable daily necessity for women during their menstrual period, playing a crucial role in their quality of life and health.

[0003] Existing panty liners have a small adhesive layer, making them prone to displacement and leakage. They also have poor absorption efficiency, and detached blood clots and secretions often block menstrual flow. These non-absorbable substances accumulate at the point of contact between the panty liner and the body, easily breeding bacteria and causing cross-infection. They can also reduce the absorbency of the panty liner, leading to leakage, especially when the user is lying on their back or side, where menstrual blood can easily leak from the back and sides of the panty liner, staining bedding. Utility Model Content

[0004] This invention provides a protective wing leak-proof pad to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a leak-proof protective pad, comprising: a pad body, an adhesive layer attached to the bottom of the pad body, an absorbent layer on the top of the pad body, a plurality of barrier columns arranged around the circumference of the absorbent layer on the surface of the absorbent layer, a recess in the middle of the absorbent layer, a plurality of drainage strips arranged in the recess, and a leak-proof strip at the tail of the absorbent layer.

[0006] Preferably, the pad body has extended protective wings connected to both sides.

[0007] Preferably, the recess in the middle of the absorbent layer is elliptical.

[0008] Preferably, the drainage strips are radially distributed around the center of the recess in the middle of the absorbent layer.

[0009] Preferably, the middle portion of the adhesive layer has a perforated strip.

[0010] Compared with existing technologies, this utility model has the following advantages: By setting up interconnected adhesive layers, the wing-mounted leak-proof panty can be firmly adhered to the underwear. The barrier posts on the absorbent layer not only increase the friction of the wing-mounted leak-proof panty, making it less prone to displacement, but also prevent a large amount of menstrual blood from flowing out, preventing side leakage. The recess in the middle of the absorbent layer can retain blood clots and viscous substances that the absorbent layer cannot absorb, preventing non-absorbable substances from contacting the body, preventing obstruction of menstrual blood, inhibiting bacterial growth, and preventing cross-infection. The multiple drainage strips can separate absorbable menstrual blood from non-absorbable substances, guiding the absorbent layer to quickly absorb menstrual blood and improving the absorption efficiency of the absorbent layer. The leak-proof strip fills the gap between the wing-mounted leak-proof panty and the body, making them fit more closely and effectively preventing menstrual blood from flowing out. Attached Figure Description

[0016] 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.

[0017] Please see the appendix Figure 1-3This utility model discloses a leak-proof panty liner with wings, comprising: a panty liner body 2, with extended wings connected to both sides of the panty liner body 2, and an adhesive layer 1 attached to the bottom of the panty liner body 2. The outer edge of the adhesive layer 1 is attached to the outer edge of the panty liner body 2, which can better adhere the panty liner body 2 to the underwear. The middle part of the adhesive layer 1 has a hollow strip, which can be more conveniently torn off when the panty liner body 2 needs to be removed, effectively reducing the difficulty of tearing off the panty liner body 2 and improving the user experience.

[0018] Furthermore, an absorbent layer 3 is provided on the upper part of the panty liner body 2, and a plurality of barrier columns 6 are provided around the perimeter of the absorbent layer 3 on the surface of the absorbent layer 3. The barrier columns 6 can increase the friction between the panty liner and the body, making it less prone to displacement, and can also prevent a large amount of menstrual blood from flowing out, thus preventing side leakage.

[0019] Furthermore, the absorbent layer 3 has a recess in the middle, which is preferably elliptical. When menstrual blood flows out, it will preferentially contact the recess in the middle of the absorbent layer, thus preventing side leakage and retaining blood clots and viscous substances that the absorbent layer cannot absorb, thereby preventing menstrual blood blockage.

[0020] Furthermore, a plurality of drainage strips 4 are provided in the recessed part in the middle of the absorbent layer 3. The drainage strips 4 are radially distributed around the center of the recessed part in the middle of the absorbent layer 3. The drainage strips 4 can separate absorbable menstrual blood from non-absorbable substances, guide the absorbent layer to quickly absorb menstrual blood, and improve the absorption efficiency of the absorbent layer.

[0021] Furthermore, a leak-proof strip 5 is provided at the tail of the absorbent layer 3. The leak-proof strip 5 fills the gap between the wing leak-proof pad and the body, making the two fit more closely and effectively preventing menstrual blood from flowing out when lying on the back or side.

[0022] When using the panty liner, the user opens the packaging and attaches the adhesive layer 1 to the panty. The extended wings on both sides of the panty liner body 2 are then folded down, and the two are bonded together by the adhesive layer 1, thus completing the fixation. When menstrual blood flows out, it is preferentially absorbed by the central recess of the absorbent layer 3. The drainage strip 4 located in the recess drains excess menstrual blood outside the recess, while blood clots and non-absorbable substances discharged with it remain in the recess, preventing contact with the body, blocking menstrual blood flow, inhibiting bacterial growth, and avoiding cross-infection.

[0023] When the user is lying on their back, side, or experiencing heavy menstrual bleeding, the barrier post 6 and leak-proof strip 5 on the panty liner body 2 can effectively prevent menstrual blood from flowing out.

[0024] Compared with existing technologies, this utility model has a simple and convenient design, is easy to use and replace, and has a lower cost. It improves the performance of sanitary pads and the quality of life for women during menstruation, and has good practicality and market prospects.

[0025] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
