Description

Technical Field

[0001] This utility model belongs to the field of feminine hygiene products technology, and in particular relates to a sanitary napkin with a diverting, upturned absorbent tampon. Background Technology

[0002] Sanitary towels are made of a polymer and polymer composite paper formed from cotton, non-woven fabric, pulp, or a combination of these materials. They are primarily used as hygiene products for women during menstruation. Leak-proof performance has always been a key focus of research and development for sanitary towels. For example, utility model patent CN202410867085.7 provides a leak-proof sanitary towel that features a first convex section on the left and right sides of the core absorbent area, and a second convex section on the front and back sides. These first and second convex sections form a ring-shaped enclosure structure, effectively blocking menstrual blood from flowing out of the core absorbent area and reducing the risk of side leakage. However, the second convex section in this design is a continuous horizontal straight line, which cannot sink into the groove between the vaginal opening and anus, or into the groin area. This allows menstrual blood to easily flow out through the groove, affecting the leak-proof effect. Utility Model Content

[0003] Based on the aforementioned problems in the existing technology, this utility model provides a sanitary napkin with a diverting, upturned absorbent tampon, which includes a bottom layer, an absorbent layer fixedly disposed on the bottom layer, and an elastic, fluffy absorbent tampon disposed on the absorbent layer. The absorbent tampon can be made of fluffy cotton or other natural fluffy materials. The absorbent tampon is adapted to the size of the human groin. The absorbent tampon includes an integrally formed, interconnected fixed part and a free part. The fixed part is used to press and fix it to the absorbent layer, and the free part is not connected to the absorbent layer and is upturned.

[0004] The absorbent swab has an inwardly recessed guide groove that extends towards the front end of the absorbent swab and guides the water flow, but does not extend to the rear end of the absorbent swab.

[0005] The absorbent cotton strip is provided with several guide grooves, and there are connecting grooves between the guide grooves, which connect adjacent guide grooves.

[0006] The front end of the absorbent cotton strip serves as a fixing part and is pressed and fixed to the absorbent layer. The guide groove is set in the fixing part, and the rear end of the absorbent cotton strip naturally curves upward to form a free part.

[0007] The rear end of the absorbent swab serves as a fixed part, and the rear end of the absorbent swab is pressed and fixed to the absorbent layer, while the front end naturally curves upward to form a free part, and the guide groove is set in the free part.

[0008] The absorbent swab has a middle section as a fixed part, which is pressed and fixed to the absorbent layer. The front and rear ends naturally curve upward to form two free parts, and the guide groove is set on the free part at the front end of the absorbent swab.

[0009] The beneficial effects of this utility model are:

[0010] 1. The free end of the absorbent tampon curves upwards to conform to the body's contours and can be inserted into the groin and the groove between the vaginal opening and anus for better sealing. Simultaneously, the tampon features inward-curving channels to guide menstrual blood towards the core absorbent layer. This combination of drainage and sealing enhances leak-proof performance.

[0011] 2. The fluffy nature of tampons causes them to deform when squeezed, squeezing out the internal air. When the deformation returns to its original state, they will reabsorb air. In other words, when the body moves, the tampons are constantly squeezed, creating a breathing effect, improving ventilation and breathability, keeping the user dry, and providing a better user experience.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] As attached Figure 1-4 The sanitary napkin shown includes a bottom layer 1, with side wings 2 on both sides of the bottom layer 1. An absorbent layer 3 is fixedly disposed on the upper surface of the bottom layer 1, and leak-proof protrusions 4 are provided around the periphery of the absorbent layer 3, surrounding the core absorbent layer 3. An absorbent tampon 5 is disposed on the absorbent layer 3. The absorbent tampon 5 is made of fluffy cotton and is adapted to the size of the human groin. The absorbent tampon 5 includes an integrally formed and interconnected fixed part 51 and a free part 52. The front end of the absorbent cotton strip 5 serves as a fixing part 51 and is pressed and fixed to the absorbent layer 3 through a pressing process. During the pressing and fixing process, the absorbent cotton strip 5 naturally forms an inwardly concave guide groove 53 at the pressing position. The guide groove 53 extends towards the front end of the absorbent cotton strip 5 and guides the flow. The guide groove 53 does not extend to the rear end of the absorbent cotton strip 5. The rear end of the absorbent cotton strip 5 serves as a free part 52 and is not connected to the absorbent layer 3. Under the action of the fluffy characteristics of the cotton, it naturally curls upward to form an arc shape.

[0026] The method for manufacturing sanitary napkins provided in this embodiment includes the following steps: using fluffy cotton to make an absorbent tampon 5 that is adapted to the size of the human groin; then pressing and fixing a part of the absorbent tampon 5 to the absorbent layer 3 to form a fixing part 51; allowing the other part of the absorbent tampon 5 to naturally curl upward to form a free part 52; when pressing and fixing the absorbent tampon 5, pressing along the front and rear extension direction of the absorbent tampon 5, and forming a front and rear extending guide groove 53 by pressing together.

[0027] When in use, the absorbent tampon 5 can be inserted into the groove between the vaginal opening and anus, as well as into the groin, to seal the groin area and prevent menstrual blood from flowing out from these areas. When the menstrual flow is heavy, the blood will flow along the guide groove 53 to the absorbent layer 3 and be absorbed. Through the combination of guidance and sealing, the flow of menstrual blood can be better controlled, preventing leakage.

[0028] In addition, the process of sitting down and standing up, walking, or changing sitting posture will cause the tampon 5 to be squeezed and released. When the tampon 5 is squeezed and released, it will squeeze out and absorb air. The squeezing and releasing will promote the flow of air, which can improve the ventilation and breathability, and keep dry and comfortable.

[0029] Example 2:

[0030] The difference between this embodiment and Embodiment 1 is that the upward direction of the absorbent cotton strip 5 is reversed, as shown in the attached figure. Figure 5 and 6 The sanitary napkin shown is a sanitary napkin with a diverting and upturned absorbent tampon 5. The front end of the absorbent tampon 5 is first pressed to form a diverting groove 53, and then the rear end is used as a fixing part 51. The rear end of the absorbent tampon 5 is pressed or glued to the absorbent layer 3 as a whole, and the front end naturally curves up to form a free part 52.

[0031] The sanitary napkin provided in this embodiment has a similar effect to the sanitary napkin provided in Embodiment 1, providing users with another option.

[0032] Example 3:

[0033] The difference between this embodiment and Embodiment 1 is that both ends of the absorbent cotton strip 5 are curved upwards, as shown in the attached figure. Figure 7 and 8 The sanitary napkin shown is a sanitary napkin with a diverting and upturned absorbent tampon 5. The front end of the absorbent tampon 5 is first pressed to form a diverting groove 53, and then the middle part is used as a fixing part 51. The middle part of the absorbent tampon 5 is pressed or glued to the absorbent layer 3 as a whole, and the front and rear ends are naturally upturned to form two free parts 52.

[0034] The sanitary napkin provided in this embodiment has a similar effect to the sanitary napkin provided in Embodiment 1, providing users with another option.

[0035] Example 4:

[0036] The difference between this embodiment and Embodiment 1 lies in the number of guide grooves 53 on the absorbent cotton strip 5, as shown in the attached figure. Figure 9 The sanitary napkin shown has an upturned absorbent tampon 5 for drainage. The front end of the absorbent tampon 5 serves as a fixing part 51 and is pressed and fixed to the absorbent layer 3 by a pressing process. During the pressing and fixing process, the absorbent tampon 5 naturally forms two parallel, inwardly concave drainage grooves 53 at the pressing position. The sanitary napkin provided in this embodiment has a similar effect to the sanitary napkin provided in Embodiment 1 and has a better drainage effect.

[0037] Example 5:

[0038] The difference between this embodiment and Embodiment 1 lies in the number of guide grooves 53 on the absorbent cotton strip 5, as shown in the attached figure. Figure 10The sanitary napkin shown has an upturned absorbent tampon 5 for drainage. The front end of the absorbent tampon 5 serves as a fixing part 51 and is pressed and fixed to the absorbent layer 3 by a pressing process. During the pressing and fixing process, the absorbent tampon 5 naturally forms three parallel, inwardly concave drainage grooves 53 at the pressing position. The sanitary napkin provided in this embodiment has a similar effect to the sanitary napkin provided in Embodiment 1 and has a better drainage effect.

[0039] Example 6:

[0040] The difference between this embodiment and embodiment five is that a connecting groove 54 is added to the absorbent cotton strip 5, as shown in the attached figure. Figure 11 The present invention relates to a sanitary napkin with an upturned absorbent tampon 5 for guiding water flow. The absorbent tampon 5 has three parallel guide grooves 53 and three connecting grooves 54 between adjacent guide grooves 53, for a total of six connecting grooves 54. The connecting grooves 54 are perpendicular to the guide grooves 53 and connect to adjacent guide grooves 53. The sanitary napkin provided in this embodiment has a similar effect to the sanitary napkin provided in embodiment five.
