Technical Field
[0001] The utility model relates to the technical field of disposable absorbent articles, in particular to a multi-layer herbal nursing sanitary napkin and a panty liner. Background Art
[0002] Both sanitary napkins and panty liners include a liquid-permeable surface layer, an absorbent core, and a liquid-impermeable bottom layer. The surface layer and the bottom layer are heat-sealed to wrap the absorbent core inside. The difference is that sanitary napkins are larger than panty liners and have side wings that are attached to the outer surface of underwear. The absorbent core structure of existing panty liners and sanitary napkins has poor drainage effect in the front-to-back direction. During use, the front and back sides often fail to absorb liquid, but leakage occurs in the middle.
[0003] In order to solve the above problems, this case proposes a sanitary napkin and panty liner that can improve the front and rear flow diversion effect and avoid side leakage. Utility Model Content
[0004] Therefore, in view of the above-mentioned problems, the utility model proposes a multi-layer herbal sanitary napkin and panty liner which can improve the front and rear flow guiding effect and avoid side leakage.
[0005] In order to solve the above technical problems, the solution adopted by the utility model is: a multi-layer herbal care sanitary napkin and panty liner, including a disposable absorbent body; the disposable absorbent body includes a surface layer, an absorbent core, and a bottom layer arranged from top to bottom, the absorbent core includes an absorbent layer, a quick-absorption guide layer that absorbs faster than the absorbent layer to guide liquid in the front and rear directions and absorb liquid from the inside to the outside, the quick-absorption guide layer is arranged on the upper surface of the absorbent layer, and a protrusion is provided on the middle part of the upper surface of the quick-absorption guide layer, which protrudes upward along the front and rear directions, and downward infiltration holes are evenly opened on the protrusion and penetrate the quick-absorption guide layer, and a herbal care layer is arranged on the protrusion, and the left and right sides of the absorbent layer are folded toward the upper surface of the quick-absorption guide layer to form a guide groove that exposes the protrusion.
[0006] A further improvement is that the thickness of the quick-absorbing guide layer is greater than the thickness of the absorption layer.
[0007] A further improvement is that the width of the protrusion is equal to the width of the guide groove.
[0008] A further improvement is that the quick-absorption guide layer is shorter than the absorbent layer and is centrally arranged inside the absorbent layer.
[0009] A further improvement is that the herbal care layer is arranged in the middle section of the raised portion.
[0010] A further improvement is that the material of the quick-absorption guide layer is pure cotton.
[0011] A further improvement is that the surface layer is a hydrophilic non-woven fabric.
[0012] A further improvement is that the bottom layer is a PE film layer.
[0013] A further improvement is that the absorption layer comprises an upper spunlace nonwoven fabric layer, a water-absorbent polymer particle layer, and a lower spunlace nonwoven fabric layer.
[0014] By adopting the above technical solution, the beneficial effects of the utility model are:
[0015] In this case, the absorbent core of the sanitary napkin and panty liner is coated with a layer of quick-absorption guide layer in the absorbent layer, and the quick-absorption guide layer is exposed through the guide groove; the quick-absorption guide layer is located at the guide groove and the upward protrusion is set. The downward infiltration hole opened on the protrusion increases the liquid absorption area and liquid absorption speed of the quick-absorption guide layer, and the quick-absorption guide layer prevents the menstrual fluid from seeping from the inside to the absorbent layer, which is conducive to keeping the surface of the sanitary napkin and panty liner dry and improving the use experience.
[0016] A further beneficial effect is that the polymer water-absorbing particles are very absorbent, and a thin layer can meet the absorption of menstrual fluid for a whole day. In addition, people nowadays have a strong awareness of maintenance and will change it once every half a day. A thin layer of polymer water-absorbing particles can fully meet the absorption, which makes the sanitary napkin and panty liner very light and thin as a whole. Being too light and thin will cause psychological burden to the user, who is worried about insufficient absorption of liquid and easy leakage, etc. Therefore, the multi-layer structure of the accelerated absorption and diversion layer is used to increase the overall thickness of the sanitary napkin to eliminate the psychological burden of the user.
[0017] A further beneficial effect is that the quick-absorption guide layer is shorter than the absorbent layer and is centrally disposed inside the absorbent layer, so that the main absorption position of the liquid is the middle section of the sanitary napkin, thereby avoiding front-to-back flow conduction and also avoiding leakage at the tail.

[0024] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments. Example
[0025] refer to Figures 1 to 3 The utility model discloses a multi-layer herbal nursing sanitary napkin, comprising a sanitary napkin body; the sanitary napkin body comprises a surface layer 10, an absorbent core, and a bottom layer 11 arranged from top to bottom, the surface layer 10 and the bottom layer 11 are both provided with wings 12, the bottom surface of the bottom layer 11 and the bottom surface of the wings 12 are both provided with a glue layer 13, and a tearing layer 14 is provided on the glue layer 13. The surface layer 10 is a hydrophilic non-woven fabric. The bottom layer 11 is a PE film layer.
[0026] The absorbent core comprises an absorbent layer 15, and a fast-absorbing guide layer 16 which absorbs faster than the absorbent layer 15 to guide the liquid in the front and rear directions and absorb the liquid from the inside to the outside. The fast-absorbing guide layer 16 is made of pure cotton. The absorbent layer 15 comprises an upper spunlace non-woven fabric layer 151, a water-absorbing polymer particle layer 152, and a lower spunlace non-woven fabric layer 153. The fast-absorbing guide layer 16 is arranged on the upper surface of the absorbent layer 15, and a protrusion 17 is provided in the middle of the upper surface of the fast-absorbing guide layer 16, which is protruding upward along the front-to-back direction. The protrusion 17 is evenly provided with downward infiltration holes 18 that penetrate the fast-absorbing guide layer 16, and a herbal care layer 19 is provided on the protrusion 17. The left and right sides of the absorbent layer 15 are folded toward the upper surface of the fast-absorbing guide layer 16 to form a guide groove 20 that exposes the protrusion 17. The quick-absorbing protrusion 17 absorbs liquid faster than the absorption layer 15. The provision of the lower seepage hole 18 increases the liquid absorption area of the protrusion 17, further improving the overall liquid absorption speed of the quick-absorbing guide layer 16, so that the quick-absorbing guide layer 16 absorbs the liquid first, and guides the liquid back and forth and diffuses laterally inside the absorption layer 15, so that the sanitary napkin as a whole absorbs menstrual fluid from the inside to the outside, which is beneficial to keeping the surface of the sanitary napkin dry and improving the feeling of use.
[0027] The thickness of the quick-absorbing guide layer 16 is greater than that of the absorption layer 15. The water absorption of the polymer water-absorbing particles is very strong, and a thin layer can meet the absorption of menstrual fluid for a whole day. In addition, people nowadays have a strong awareness of maintenance, and they will change it once every half a day. A thin layer of polymer water-absorbing particles can meet the absorption, so the sanitary napkin is very thin and light as a whole. However, being too thin will cause psychological burden on the user, who may worry about insufficient absorption of liquid and easy leakage, etc. Therefore, the thickness of the quick-absorbing guide layer 16 is used to increase the overall thickness of the sanitary napkin to eliminate the psychological burden on the user.
[0028] The width of the protrusion 17 is equal to the width of the guide groove 20 to maximize the absorption area of the protrusion 17 .
[0029] The quick-absorption guide layer 16 is shorter than the absorbent layer 15 and is centrally disposed inside the absorbent layer 15, so that the main absorption position of liquid is the middle section of the sanitary napkin, thereby avoiding front-to-back flow conduction and tail leakage.
[0030] The herbal care layer 19 is arranged in the middle section of the protrusion 17 to shorten the length of the herbal care layer 19 and reduce the cost of herbal materials. The herbal care layer 19 is formed by sprinkling one or more ultrafine particles of herbal ingredients such as mint leaves, honeysuckle, tongcao, tuckahoe, euryale, coix seeds, agrimony, centella asiatica, snow lotus, etc. on the upper surface of the protrusion 17; the herbal care layer 19 can also be formed by spraying one or more composite herbal icy essential oil sprays of herbal ingredients such as mint leaves, honeysuckle, tongcao, tuckahoe, euryale, coix seeds, agrimony, centella asiatica, snow lotus, etc. on the surface of the water-absorbing non-woven fabric. It is preferred to use herbal essential oils to spray the surface of the water-absorbing non-woven fabric. Example

The surface layer 10' is a hydrophilic non-woven fabric. The bottom layer 11' is a PE film layer.
[0032] The absorbent core includes an absorbent layer 14', a fast-absorbing guide layer 15' that absorbs faster than the absorbent layer 14' to guide the liquid in the front and rear directions and absorb liquid from the inside to the outside. The fast-absorbing guide layer 15' is made of pure cotton. The absorbent layer 14' includes an upper spunlace non-woven fabric layer 141', a water-absorbent polymer particle layer 142', and a lower spunlace non-woven fabric layer 143'. The fast-absorbing guide layer 15' is arranged on the upper surface of the absorbent layer 14', and a protrusion 16' is provided in the middle of the upper surface of the fast-absorbing guide layer 15', which protrudes upward along the front-to-back direction. The protrusion 16' is evenly provided with lower infiltration holes 17' that penetrate the fast-absorbing guide layer 15', and a herbal care layer 18' is provided on the protrusion 16'. The left and right sides of the absorbent layer 14' are folded toward the upper surface of the fast-absorbing guide layer 15' to form a guide groove 19' that exposes the protrusion 16'. The liquid absorption speed of the quick-absorbing protrusion 16' is faster than that of the absorption layer 14'. The provision of the lower seepage hole 17' increases the liquid absorption area of the protrusion 16', further improving the overall liquid absorption speed of the quick-absorbing guide layer 15', so that the quick-absorbing guide layer 15' absorbs the liquid first, and guides the liquid back and forth and diffuses laterally inside the absorption layer 14', so that the pad as a whole absorbs menstrual fluid from the inside to the outside, which is beneficial to keeping the surface of the pad dry and improving the use feeling.
[0033] The thickness of the quick-absorbing guide layer 15' is greater than that of the absorption layer 14'. The water absorption of the polymer water-absorbing particles is very strong, and a thin layer can meet the absorption of menstrual fluid for a whole day. In addition, people nowadays have a strong awareness of maintenance, and they will change it every half a day. A thin layer of polymer water-absorbing particles can meet the absorption, so the overall pad is very thin. However, being too thin will cause psychological burden on the user, who may worry about insufficient absorption of liquid and easy leakage, etc. Therefore, the thickness of the quick-absorbing guide layer 15' is used to increase the overall thickness of the pad to eliminate the psychological burden on the user.
[0034] The width of the protrusion 16 ′ is equal to the width of the guide groove 19 ′, so as to maximize the absorption area of the protrusion 16 ′.
[0035] The quick-absorbing guide layer 15' is shorter than the absorbent layer 14' and is centrally disposed inside the absorbent layer 14', so that the main absorption position of liquid is the middle section of the pad, thereby avoiding front-to-back flow conduction and tail leakage.
[0036] The herbal care layer 18' is arranged in the middle section of the protrusion 16' to shorten the length of the herbal care layer 18' and reduce the cost of herbal materials. The herbal care layer 18' is formed by sprinkling one or more ultrafine particles of herbal ingredients such as mint leaves, honeysuckle, tongcao, tuckahoe, euryale, coix seeds, agrimony, centella asiatica, snow lotus, etc. on the upper surface of the protrusion 16'; the herbal care layer 18' can also be formed by spraying one or more composite herbal icy essential oil sprays of herbal ingredients such as mint leaves, honeysuckle, tongcao, tuckahoe, euryale, coix seeds, agrimony, centella asiatica, snow lotus, etc. on the surface of the water-absorbing non-woven fabric. It is preferred to use herbal essential oils to spray the surface of the water-absorbing non-woven fabric.
