Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkins, in particular to a leak-proof panty-shaped sanitary napkin. Background Art

[0002] Panty-shaped sanitary napkins are a type of sanitary product used by women during menstruation. Because they are like underwear, they have good wrapping properties and good leak-proof effects, and are becoming more and more popular among women. In the actual use of consumers, most of the menstrual blood is concentrated in the middle crotch area of the panty-shaped sanitary napkin. As the number of absorption times increases, the absorption speed of the product gradually slows down. There are still some consumers who experience leakage on the left and right sides of the crotch during use. To solve the above problems, most manufacturers of panty-shaped sanitary napkins solve the problem by improving the absorption speed of the product, increasing the absorption capacity, and raising the anti-leakage layers on both sides. However, during a woman's menstrual period, most women will experience multiple gushes of menstrual blood in a certain period, with a large amount and fast flow rate of menstrual blood. The current products may still not be able to absorb the menstrual blood of multiple gushes in time. The unabsorbed menstrual blood will slide to both sides on the surface layer of the panty-shaped sanitary napkin. Since the anti-leakage layers on both sides do not have an absorption function, and the anti-leakage layers on both sides may be contaminated by menstrual blood during use, or be pressed by the consumer's legs and unable to stand up, they cannot block the menstrual blood, resulting in leakage. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a leak-proof panty-shaped sanitary napkin in view of the deficiencies of the prior art. The anti-leakage layers on both sides of this panty-shaped sanitary napkin can absorb menstrual blood in time, prevent the menstrual blood from sliding to both sides, and prevent leakage.

[0004] The technical solution for realizing the purpose of the utility model is as follows:

[0005] A leak-proof panty-shaped sanitary napkin includes an elastic pant body at the waist and an absorbent body provided inside the pant body. There are tear-open openings at the joints on both sides of the front and rear pieces of the pant body. The absorbent body includes a surface layer, an absorbent layer, and a bottom anti-seepage layer that are stacked in sequence from top to bottom. First protrusions extending outward are provided in the middle of both sides of the absorbent layer. After the long sides of the surface layer are folded downward, part of the surface layer wraps the absorbent layer. Second protrusions extending outward are provided in the middle of both sides of the bottom anti-seepage layer. The anti-seepage layer is in a C shape, and the anti-seepage layer wraps the second protrusion in the middle of the bottom anti-seepage layer. The width of the wrapped area is greater than the distance from the edge of the side anti-seepage layer to the midline of the through holes on both sides of the absorbent layer.

[0006] The width of the middle part of both sides of the absorbent layer is greater than the width of the two ends. The length of the absorbent layer is 400 mm - 500 mm, and the width is 60 - 150 mm. The length of the first protrusion in the middle of the absorbent layer is 80 mm - 150 mm, and the width is 20 mm - 40 mm.

[0007] On both sides of the middle of the absorption layer, there are strip-shaped through holes along the longitudinal length direction. The center line of the through hole coincides with the long edge line of the front and rear ends of the absorption layer. The longitudinal length of the through hole is 60 - 130 mm, and the transverse width is 5 mm - 10 mm. On the center line within the two end points at the junction of the center line of the through hole and the second protrusion, there are pressing points in close contact. The forming method of the pressing points can adopt hot pressing or ultrasonic pressing process. The shape of the pressing points is not limited, and the area of the pressing points is 1 mm 2 - 12 mm 2 .

[0008] After the long side of the surface layer is folded downwards, it partially wraps the absorption layer, and the width of the wrapping area is 10 mm - 30 mm.

[0009] The anti-leakage layer is provided with elastic rubber bands at the part wrapped with the absorption layer. The distance between the elastic rubber bands is 3 mm - 5 mm. The elastic rubber bands are stretched by production equipment before bonding. After bonding with the two anti-seepage layers on both sides, a state of contraction is formed in the longitudinal direction of the two anti-seepage layers on both sides, so that the first protrusion and the second protrusion stand upright inward.

[0010] Long strip-shaped anti-slip silica gel strips are arranged at intervals on the edge of the second protrusion on the side of the anti-leakage layer. The length of the anti-slip silica gel strips is 80 mm - 150 mm, and the width is 3 mm - 10 mm. The anti-slip silica gel strips can further improve the side leakage caused by the gap generated by the movement of the crotch when the user is wearing.

[0011] Compared with the prior art, the technical solution has the following beneficial effects:

[0012] For this panty-shaped sanitary napkin, the absorption layer has increased areas wider than the front and rear areas of the absorption layer on both sides in the middle, and through holes and pressing points are added on both sides to quickly absorb menstrual blood. The elastic rubber bands and anti-slip strips provided on the anti-leakage layer provide functions of anti-slip and body-fitting, and also provide a certain support for the core body. The product fits with the deformation of the human body structure, reducing the risk of side leakage and having a good anti-side leakage effect. BRIEF DESCRIPTION OF THE DRAWINGS
