[0002] Existing sanitary napkins are composed of absorbent cores, wings and other structures, which can absorb menstrual blood and prevent side leakage to a certain extent. In order to achieve better side leakage prevention, most products use traditional elastic three-dimensional guards to achieve better protection even at night when the amount of menstrual flow is large. However, the three-dimensional guards bring a certain degree of tightness and foreign body feeling to the legs. It is necessary to achieve better comfort for users while preventing side leakage, improve the user experience of sanitary napkins, and reduce the discomfort of female compatriots during menstruation. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a sanitary napkin that prevents side leakage. The wing structure is improved to eliminate the foreign body sensation on the legs, achieve a non-sensing use experience, and greatly reduce the occurrence of side leakage.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0031] Example 1

[0032] like Figures 1 to 3 , Figure 6 The figure shows a first embodiment of a side leakage prevention sanitary napkin of the utility model, comprising an absorbent body 1 and wings 2. The number of the wings 2 is two, and the two wings 2 are symmetrically mounted on both sides of the absorbent body 1. The height of the wings 2 protruding from the surface of the absorbent body 1 on the side close to the absorbent body 1 is greater than the height of the wings 2 protruding from the surface of the absorbent body 1 on the side away from the absorbent body 1.

[0033] Here, the height of the wing 2 protruding from the surface of the absorbent body 1 on the side close to the absorbent body 1 is greater than the height of the wing 2 protruding from the absorbent body 1 on the side away from the absorbent body 1. This is due to the difference in the top height of the wing 2 when the bottoms of the wing 2 are on the same horizontal plane when the wing 2 is placed horizontally. In other words, the thicknesses on both sides of the wing 2 are different.

[0034] The height of the side wings 2 of the absorbent body 1 can be increased in many ways, such as stacking or folding multiple layers, or partially bulging the structure, or using different materials on both sides of the wings 2 to make them have different fluffiness; all of the above settings can meet the purpose of the utility model. In this embodiment, the first solution and the second solution are combined. Of course, within the scope of knowledge of those skilled in the art, the purpose of the utility model can also be achieved by the first solution or the second solution alone.

[0035] As an embodiment of the present invention, the wing 2 includes at least a first layer 21 and a second layer 22, the first layer 21 is covered on the second layer 22, the second layer 22 is connected to the top of the absorption body 1 near the bottom of the absorption body 1 or the second layer 22 is connected to the side edge of the absorption body 1 near the side of the absorption body 1.

[0036] The first layer 21 is a skin contact layer for the user, and the second layer 22 is a transition layer between the first layer 21 and the absorbent body 1. By setting the internal structures of the first layer 21 and the second layer 22 accordingly, the height of the first layer 21 and the second layer 22 on the side close to the absorbent body 1 is higher than the height on the side away from the absorbent body 1. There are two ways to connect the second layer 22 and the absorbent body 1. One is to set the second layer 22 partially on the absorbent body 1, which can increase the height of the wing 2 in the vertical direction close to the absorbent body 1; the other is to set the second layer 22 on the side of the top of the absorbent body 1. This structure needs to rely on the height of the second layer 22 and the first layer 21 to achieve the height of the wing 2 at the side of the absorbent body 1 in the longitudinal direction. It is higher than the height of the absorbent body 1 itself, and in accordance with the principle that the liquid flows to the lower place, the side leakage prevention of the sanitary napkin is achieved. The bottom of the first layer 21 is bonded to the top of the second layer 22 by the colloid 4. The colloid 4 can be a hot melt adhesive or a structural adhesive, so that there is adhesion between the two layers of materials, so that the two layers of wings 2 will not be delaminated.

[0037] As an embodiment of the present invention, the first layer 21 has a first cavity 211 disposed inside the first layer 21 near the absorbent body 1 , and the second layer 22 has a second cavity 221 disposed inside the second layer 22 near the absorbent body 1 .

[0038] The first layer 21 can be made of a silky hot air material, with a fiber of 0.5 denier to 2.0 denier and a unit square gram weight of 12g to 25g, to increase skin-friendly properties. The second layer 22 can be made of a hot air non-woven fabric with high curl and high fluffiness, with a fiber of 1.5 denier to 2.5D, which can effectively increase the thickness and fluffiness of the material, and a unit square gram weight of 15g to 30g, or a bicomponent spunbond material, with a unit square gram weight of 15g to 25g; within the scope of knowledge of those skilled in the art, the first layer 21 and the second layer 22 can also be made of the same material.

[0039] As an embodiment of the present invention, the first cavity 211 is filled with a first fluffy object 31 , and the second cavity 221 is filled with a second fluffy object 32 .

[0040] Both the first fluffy object 31 and the second fluffy object 32 can play a fluffy role, increase the height of the first layer 21 and the second layer 22 close to the absorbent body 1, and the first fluffy object 31 and the second fluffy object 32 can be made of the same or different materials; of course, only the first cavity 211 of the first layer 21 can be filled, while the second cavity 221 of the second layer 22 is not filled, or only the second cavity 221 is filled, while the first cavity 211 is not filled; or both cavities can be filled at the same time. Furthermore, it is also possible to set a cavity only in the first layer 21 or only in the second layer 22.

[0041] As an embodiment of the present invention, the first fluffy object 31 and the second fluffy object 32 are both made of one or more of PE, PP, and PET.

[0042] The first fluffy material 31 and the second fluffy material 32 can be made of a mixture of one or more of PE, PP, and PET, and are cut from high-loft hot air non-woven fabrics; they are made of a mixture of fine denier and coarse denier fibers, with 2 denier fibers accounting for 10%-40%, 4 denier fibers accounting for 20%-50%, and 6 denier fibers accounting for between 40%-60%. Within the scope of knowledge of those skilled in the art, the first fluffy material 31 and the second fluffy material 32 can also be made of other materials.

[0043] As an embodiment of the present invention, the edge of the first layer 21 close to the absorption body 1 is flush with the edge of the second layer 22 close to the absorption body 1 .

[0044] While increasing the longitudinal thickness of the wing 2 close to the absorbent body 1 , the edge can also be made neat and more refined in appearance; of course, the edge of the second layer 22 can also be set to protrude from the edge of the first layer 21 on the absorbent body 1 side.

[0045] As an embodiment of the present invention, the surface of the first layer 21 and / or the surface of the second layer 22 is made of a hydrophobic material.

[0046] The hydrophobic material has a good hydrophobic effect, thereby effectively blocking the liquid in the surface layer 11, achieving a comfortable experience for the legs, and further improving the effect of preventing side leakage.

[0047] As an embodiment of the present invention, the first layer 21 and the second layer 22 partially overlap in the projection direction, and the area of ​​the first layer 21 is larger than the area of ​​the second layer 22 .

[0048] In this embodiment, in the projection direction, the first layer 21 completely covers the second layer 22 .

[0049] The first layer 21 can be a structure with the same thickness, and the length of the second layer 22 extending toward the side away from the absorption body 1 can be different from that of the first layer 21. By arranging the second layer 22 on the side close to the absorption body 1, the side away from the absorption body 1 does not have the second layer 22 when viewed from the longitudinal cross-sectional structure. In this way, by arranging different numbers of layers at different positions of the protective wing 2, the height of the protective wing 2 close to the absorption body 1 can be higher than the height away from the absorption body 1.

[0050] As an embodiment of the present invention, the interior of the first layer 21 away from the first cavity 211 is connected to the interior of the second layer 22 away from the second cavity 221 .

[0051] Example 2

[0052] The following is a second embodiment of a sanitary napkin for preventing side leakage of the utility model. This embodiment is similar to the first embodiment, except that air is inflated in the first cavity 211 and / or the second cavity 221 to increase the height of the first layer 21 and / or the second layer 22 close to the absorbent body 1, and by inflating air into the cavity, the side of the wing 2 close to the absorbent body 1 has a structure similar to an airbag, which can not only meet the function of preventing side leakage, but also reduce the foreign body sensation and increase comfort.

[0053] Example 3

[0054] like Figure 4The third embodiment of the utility model is a side leakage prevention sanitary napkin. This embodiment is similar to the first embodiment, except that the second layer 22 and the first layer 21 are separated from each other on the side close to the absorbent body 1, but the second layer 22 is connected to the first layer 21 on the side away from the absorbent body 1, so that the material of the second layer 22 can be reduced. The first layer 21 and the second layer 22 are integrally formed by folding. After folding, structural adhesive is used for bonding. The structural adhesive can be applied in a spiral or hollow scraping form between the first layer 21 and the second layer 22, thereby reducing the amount of adhesive used and increasing the softness of the material; the unbonded part can form a certain cavity, the width of which is between 0mm-10mm, and the cavity can effectively improve the softness and fluffiness of the material.

[0055] As an embodiment of the utility model, the absorbent body 1 comprises a surface layer 11, a core layer 12, and a waterproof bottom layer 13 arranged in sequence from top to bottom, the wing 2 is arranged above the surface layer 11, the second layer 22 is connected to the surface layer 11, and the first layer 21 is connected to the waterproof bottom layer 13 away from the absorbent body 1. Further, a guide layer 14 is added at the bottom of the surface layer 11, the width of the guide layer 14 is 50%-80% of the width of the core layer 12, and the length is 50%-80% of the length of the core layer 12. A plurality of small holes 15 are irregularly distributed in the middle of the guide layer 14, and the opening rate is between 10%-80%, so that the liquid can quickly penetrate.

[0056] Menstrual blood is absorbed by the surface layer 11 and reaches the core layer 12 to be further absorbed and stored. The waterproof bottom layer 13 is a waterproof film. The back of the waterproof bottom layer 13 and the back of the wing 2 are both provided with adhesive, which can effectively fix the product on the underwear so as to prevent displacement.

[0057] Example 4

[0058] like Figure 5 The fourth embodiment of the utility model is shown as a side leakage prevention sanitary napkin. This embodiment is similar to the first embodiment, except that the first layer 21 and the second layer 22 completely overlap in the projection direction, and the area of ​​the first layer 21 is equal to the area of ​​the second layer 22.

[0059] In this embodiment, the absorbent body 1 includes a surface layer 11, a core layer 12, and a waterproof bottom layer 13 arranged in sequence from top to bottom, the wing 2 is arranged above the surface layer 11, the second layer 22 is connected to the surface layer 11, and the first layer 21 is connected to the waterproof bottom layer 13 on the side away from the absorbent body 1. One side of the second layer 22 is connected to the surface layer 11, and the other side is connected to the waterproof bottom layer 13. Moreover, the difference between this embodiment and embodiment 2 is that the first layer 21 and the second layer 22 are completely isolated and not connected to each other.

[0060] The utility model improves the structure of the wing 2, thereby eliminating the foreign body feeling on the legs during use, achieving a non-feeling use experience, and greatly reducing the occurrence of side leakage. At the same time, effective side leakage prevention also comes from good absorption. The utility model adopts an oversized guide layer 14 and a hole-digging design, which effectively increases the speed of menstrual blood infiltration and prevents reverse osmosis to the greatest extent.

[0061] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
