Description

Technical Field

[0001] This utility model relates to the field of sanitary napkins, specifically an improved sanitary napkin. Background Technology

[0002] Sanitary napkins are hygiene products used by women during menstruation, primarily to absorb menstrual blood flowing from the vagina. The design of a sanitary napkin includes a top layer, an absorbent core, and a bottom layer, as well as soft sides to prevent leakage. When in use, the adhesive backing of the sanitary napkin allows it to be attached to underwear for hygiene. The invention of sanitary napkins can be traced back to ancient times, with the modern version invented by an American man who discovered that wrapping clean cotton fibers and highly absorbent pulp in soft fabric could create an effective hygiene product. Currently, most bathroom fixtures on the market have a symmetrical structure with equal dimensions at both ends. This type of sanitary napkin often leaks when women make vigorous movements or unconscious movements at night, significantly affecting their comfort. Therefore, it is necessary to provide a sanitary napkin that can prevent leakage and improve comfort and practicality. Furthermore, the stability of existing sanitary napkins during wear needs improvement; therefore, it is necessary to provide a sanitary napkin that improves wear stability and prevents it from falling off. Utility Model Content

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.

[0020] Please see Figure 1-4 This utility model provides an improved sanitary napkin, including a sanitary napkin component 100;

[0021] The sanitary napkin assembly 100 includes a sanitary napkin body 101, a tail wing 102 connected to the rear end of the sanitary napkin body 101, a raised ridge 103 provided at the upper end of the sanitary napkin body 101, and a bottom sheet 104 connected to the lower end of the sanitary napkin body 101. An inner adhesive 105 and an outer adhesive 106 are respectively connected to both sides of the bottom sheet 104.

[0022] In one specific embodiment, the sanitary napkin assembly 100, comprising the sanitary napkin body 101, tail wing 102, inner adhesive 105, and outer adhesive 106, along with the split-structure bottom sheet 104, not only significantly improves the anti-leakage effect of the sanitary napkin, thereby enhancing comfort and practicality, but also improves wearing stability, thus enhancing ease of use. In use, the sanitary napkin body 101 and bottom sheet 104 are first attached to the inside of underwear, with the tail wing 102 attached to the back of the underwear. Then, the inner adhesive 105 and outer adhesive 106 are wrapped around the bottom of the underwear and bonded together, thus installing the sanitary napkin body 101. Since the inner adhesive 105 and outer adhesive 106 are installed on both sides of the tail wing 102, the tail wing 102... The separate structure of the sanitary napkin body 101 and the inner adhesive 105 prevents the sanitary napkin body 101 from being pulled and deformed, causing it to narrow in the middle, when the inner adhesive 105 and the outer adhesive 106 are bonded together. This improves the tightness of the fit between the sanitary napkin body 101 and the user's skin. At the same time, the tail wing 102 can fit completely with the user's buttocks, which can further prevent side leakage. The ridge 103 at the upper end of the tail wing 102 matches the buttock cleft, which can help prevent side leakage. The bonding between the inner adhesive 105 and the outer adhesive 106 can improve the installation stability of the sanitary napkin body 101. At the same time, the tail wing 102 can increase the contact area with the buttocks, thus increasing the friction and further improving the wearing stability, thereby improving the ease of use.

[0023] Please see Figures 2-4 A first adhesive piece 111 is bonded between the sanitary napkin body 101 and the backing sheet 104.

[0024] In one specific embodiment, the first adhesive piece 111 is used to bond the separate sanitary napkin body 101 and the bottom sheet 104 together, so as to avoid deformation of the sanitary napkin body 101 when the inner adhesive 105 and the outer adhesive 106 are bonded, so as to achieve the effect of preventing side leakage.

[0025] Please see Figures 2-4 The front end of the film 104 is connected to a second adhesive piece 121.

[0026] In one specific embodiment, the second adhesive piece 121 and the underwear adhesive can help improve the adhesive stability of the sanitary napkin body 101.

[0027] Please see Figures 2-4 The sanitary napkin body 101 includes a first structural layer 1011, a second structural layer 1012 connected to the lower end of the first structural layer 1011, a third structural layer 1013 connected to the lower end of the second structural layer 1012, and a fourth structural layer 1014 connected to the lower end of the third structural layer 1013.

[0028] In one specific embodiment, the first structural layer 1011, together with the second structural layer 1012, the third structural layer 1013 and the fourth structural layer 1014, can improve the absorbency of the sanitary napkin.

[0029] Please see Figures 2-4 The first structural layer 1011 is made of pure cotton, the second structural layer 1012 is made of non-woven fabric, the third structural layer 1013 is made of polymer composite absorbent paper, and the fourth structural layer 1014 is made of dust-free paper.

[0030] In one specific embodiment, the first structural layer 1011 made of pure cotton can enhance the absorbency of the sanitary napkin, the second structural layer 1012 made of non-woven fabric can improve the overall strength of the sanitary napkin, the third structural layer 1013 made of polymer composite absorbent paper can further enhance the absorbency, and the fourth structural layer 1014 made of dust-free paper can enhance the overall functionality of the sanitary napkin.

[0031] Please see Figures 2-4 Film 104 is made of dust-free paper.

[0032] In one specific embodiment, the substrate 104 made of biodegradable paper can improve the safety of using sanitary napkins.

[0033] Working principle: In use, first, attach the sanitary napkin body 101 and the backing 104 to the inside of the underwear. At this time, the tail wing 102 is attached to the back of the underwear. Then, the inner adhesive 105 and the outer adhesive 106 are wrapped around the bottom of the underwear and bonded together to install the sanitary napkin body 101. Because the inner adhesive 105 and the outer adhesive 106 are attached to both sides of the tail wing 102, and the separate structure of the tail wing 102 and the sanitary napkin body 101, the inner adhesive 105 and the outer adhesive 106 are bonded together to prevent the sanitary napkin body 101 from being pulled and deformed, causing it to narrow in the middle. This design improves the fit between the sanitary napkin body 101 and the user's skin. The tail wing 102 can fit perfectly against the user's buttocks to further prevent side leakage. The ridge 103 at the top of the tail wing 102 matches the buttock cleft to assist in preventing side leakage. The inner adhesive 105 and the outer adhesive 106 adhere to each other to improve the installation stability of the sanitary napkin body 101. The tail wing 102 increases the contact area with the buttocks, thereby increasing friction to further improve wearing stability and thus improving ease of use.
