Abstract
Description
Technical Field
[0001] This utility model relates to the field of hygiene products technology, and more specifically, to a probiotic sanitary napkin with a cut core. Background Technology
[0002] Traditional sanitary napkins consist of three layers stacked from top to bottom: a distribution layer (or top layer), an absorbent core layer, and a leak-proof layer. The distribution layer is located on top of the absorbent core layer, and the leak-proof layer is arranged in a fan shape at its rear end, covering the bottom of the absorbent core layer to prevent menstrual blood from flowing out.
[0003] The absorbent core layer is a composite structure made of multiple materials, primarily responsible for the liquid absorption function of the sanitary napkin. The main absorbent layer contains superabsorbent polymer (SAP) particles. Due to its convex design, the guide layer fits snugly against the intimate area, quickly guiding menstrual blood downwards. The SAP particles in the main absorbent layer ensure the absorption of menstrual blood, keeping the intimate area dry. The fan-shaped leak-proof layer at the rear comprehensively prevents side and back leakage, avoiding embarrassment for women. However, because the convex design and multi-layered absorbent core layer are relatively thick in the middle, users often experience poor breathability during use. Furthermore, since the main absorbent layer is made of superabsorbent polymer, its overall rigidity is relatively high, further affecting the user experience of the sanitary napkin.
[0004] On the other hand, as people pay increasing attention to the health of their private parts, products that prevent or promote a healthy reproductive environment in the private area have emerged. Lactobacillus is one type of probiotic and the most abundant flora in the vagina of normal women. In a healthy vaginal environment, the abundance of lactobacillus can reach 97.56%–99.99%, producing substances such as lactic acid, hydrogen peroxide, and some enzymes, which are crucial for maintaining the stability of the vaginal microecological environment. Therefore, providing a hygiene product that is more beneficial to the health of women's private parts is one of the urgent problems to be solved in this field.
[0005] In view of this, this utility model is proposed. Utility Model Content

[0037] Please refer to Figure 1 The embodiment provides a probiotic sanitary napkin 100 cut by a core body, which comprises a surface layer 110, an absorbent core layer 120 and a leakage-proof layer 130 arranged in sequence.
[0038] When the core-cut probiotic sanitary napkin 100 is in use, the surface layer 110 is in direct contact with the skin, the absorbent core layer 120 is used to absorb menstrual blood, and the leakage-proof layer 130 can prevent the leakage of menstrual blood. Therefore, in the use state of the core-cut probiotic sanitary napkin 100, the surface layer 110, the absorbent core layer 120, and the leakage-proof layer 130 are sequentially stacked from top to bottom. The periphery of the surface layer 110 is fixedly connected with the periphery of the leakage-proof layer 130, so that the absorbent core layer 120 is fixed between the surface layer 110 and the leakage-proof layer 130, thereby preventing the leakage of menstrual blood.
[0039] Please refer to Figure 2 The absorbent core layer 120 is provided with a plurality of slits 121 penetrating the absorbent core layer 120 in the direction from the surface layer 110 to the leakage-proof layer 130, and at least one of the slits 121 has a first probiotic layer (not shown in the figure) adhered to the peripheral wall thereof.
[0040] It should be noted that the "first" in the first probiotic layer is only used to distinguish the position of the probiotic layer. The probiotics in the first probiotic layer can be selected from existing probiotic species that are beneficial to the adjustment of the vaginal microenvironment, such as Lactobacillus crispatus.
[0041] Since the first probiotic layer is located on the peripheral wall of the slit 121, the first probiotic layer can coat the solution containing probiotics on the corresponding tool bit during the cutting of the slit 121. When the tool bit cuts the absorbent core layer 120, the slit 121 and the first probiotic layer on the surface thereof can be formed on the absorbent core layer 120 at the same time. The process is simple to operate, and can simultaneously solve the problems of the existing core-cut probiotic sanitary napkin 100, such as high hardness, poor user experience, and complex preparation process of the existing probiotic core-cut probiotic sanitary napkin 100.
[0042] At the same time, since the surface of the similar core layer only has a surface layer 110 structure, the first probiotic layer can be transferred to the human skin by directly penetrating the surface layer 110, thereby playing a role in adjusting the vaginal microenvironment. The release process of the probiotics is reliable and beneficial to the health of the female private parts.
[0043] As shown in Figure 2 In this embodiment, the plurality of slits 121 are uniformly and spacedly distributed on the absorbent core layer 120 and arranged in an array.
[0044] As shown in Figure 3 As another optional embodiment, the plurality of slits 121 can also be arranged in an interspersed array on the absorbent core layer 120.
[0045] In order to ensure that the core-cut probiotic sanitary napkin 100 has a certain softness, improve the use experience, and at the same time avoid the displacement and side leakage caused by the too soft core-cut probiotic sanitary napkin 100, the length of each slit 121 is 10-30 mm, the width is 1-3 mm, the height is the same as the height of the absorbent core layer 120, and the distance between the adjacent two slits 121 is 0-10 mm.
[0046] For example, as shown in the embodiment provided by Figure 2 The length of each slit 121 of the core-cut probiotic sanitary napkin 100 is 20 mm, the width is 2 mm, the height is the same as the height of the absorbent core layer 120, and the distance between the adjacent two slits 121 is 5 mm.
[0047] Please refer to Figure 1 As some preferred embodiments, the surface layer 110 is provided with a plurality of through flow grooves 111. The design of the flow grooves 111 facilitates the flow of menstrual blood, promotes the uniform distribution of the menstrual blood on the surface of the absorbent core layer 120, avoids the situation that a large amount of menstrual blood is accumulated in the middle of the absorbent core layer 120 while there is little or almost no menstrual blood around, and is beneficial to the improvement of the dryness of the core-cut probiotic sanitary napkin 100 during use.
[0048] In addition, when the surface layer 110 is designed with the flow grooves 111, the flow grooves 111 provide convenience for the transfer of the probiotics in the first probiotic layer on the absorbent core layer 120 to the skin, further improve the reliability of the probiotic release process, and are beneficial to the health of the female private parts.
[0049] As a further preferred embodiment, the peripheral wall of the flow groove 111 is adhered with a second probiotic layer (not shown in the figure).
[0050] Among them, "second" in the second probiotic layer is only a distinction of the position of the probiotics, and is not a limitation of the probiotic layer. The probiotics in the second probiotic layer also select probiotic species that have a positive effect on the vaginal microenvironment, such as lactobacillus, and the specific strain can select the existing strain type.
[0051] The probiotics added in the first probiotic layer and the second probiotic layer in the embodiment can be inactivated probiotics and / or fermentation products thereof.
[0052] Similarly, since the second probiotic layer is located on the peripheral wall of the flow groove 111, during the process of opening the flow groove 111 on the surface layer 110, a solution containing probiotics can be directly coated on the needle for opening the flow groove 111, so as to form a double structure of the flow groove 111 and the second probiotic layer on the surface layer 110 in one step, the process is simpler, and at the same time, the core-cut probiotic sanitary napkin 100 is endowed with the health beneficial effect.
[0053] When the peripheral wall of the flow guide groove 111 is provided with the second probiotic layer, the probiotics on the second probiotic layer can directly contact the skin and then play a role, which is conducive to the health of the female private parts; the probiotics on the first probiotic layer can also provide the flow guide groove 111 with skin contact and then play a role. Therefore, the further preferred embodiment can improve the influence of the probiotic sanitary napkin 100 cut from the probiotic core on the health of the female private parts.
[0054] As some preferred embodiments, the absorbent core layer 120 comprises a core body and prebiotics, and the prebiotics are uniformly distributed in the core body. The prebiotics, as nutrients for probiotics, are transferred to the vaginal epidermis through constant friction after contacting the skin of the human private parts, providing nutrition for the probiotics of the human private parts and promoting the growth of the probiotics.
[0055] The absorbent core layer 120 with prebiotics can be superimposed on the basis of any of the above embodiments. When the absorbent core layer 120 contains prebiotics, due to the design of the gap 121 and the flow guide groove 111, the prebiotics can provide nutrients for the probiotics in the first probiotic layer or the probiotics in the first probiotic and second probiotic layers, and promote the growth of the probiotics.
[0056] The method of adding prebiotics to the absorbent core layer 120 and the type of prebiotics can be realized by existing methods, such as fusing the prebiotics with the SAP particles in the core body, or soaking the core body in a solution or suspension containing prebiotics, as long as the prebiotics can be uniformly distributed in the core body.
[0057] As some preferred embodiments, the surface layer 110 comprises a surface layer 110 body and postbiotics, and the postbiotics are uniformly distributed in the surface layer 110 body.
[0058] The postbiotics contain metabolites of probiotics. By adding postbiotics to the surface layer 110, the metabolites of probiotics in the postbiotics can directly contact the skin and play a role during the use of the probiotic sanitary napkin 100 cut from the core, which helps to regulate the vaginal microenvironment and promote the growth of probiotics.
[0059] Therefore, postbiotics can be added to the surface layer 110, or only the metabolites of probiotics can be added. The method of adding postbiotics to the surface layer 110 and the type of postbiotics can be realized by existing methods, such as using a coating method to coat the postbiotics on the surface layer 110, or using spraying, printing and other methods, as long as the postbiotics can be uniformly distributed on the surface layer 110 body.
[0060] Since the core-cut probiotic sanitary napkin 100 is generally large in the amount of menstrual blood in the central region and small in the amount of menstrual blood around the central region during use, the central region of the absorbent core layer 120 can have a large absorption pressure and menstrual blood can re-seep, and the regions around the central region of the absorbent core layer 120 can have a low utilization rate. Once menstrual blood re-seeps, the surface dryness of the core-cut probiotic sanitary napkin 100 during use is affected, and the user's experience is affected.
[0061] As shown in Figure 4 , as some preferred embodiments, the absorbent core layer 120 is divided into a central region 122 and a peripheral region 123 in the direction of the use contact surface of the core-cut probiotic sanitary napkin 100, and the peripheral region 123 is around the central region 122.
[0062] As shown in Figure 5 , and in the direction of the use contact surface of the core-cut probiotic sanitary napkin 100, the cross-sectional area of the individual slits 121 in the central region 122 is greater than or equal to the cross-sectional area of the individual slits 121 in the peripheral region 123.
[0063] The cross-sectional area of the individual slits 121 in the central region 122 is large, so its flow velocity is fast, which avoids the accumulation of menstrual blood in the central region 122 and is beneficial to keeping the core-cut probiotic sanitary napkin 100 dry during use. However, if the cross-sectional area of all the slits 121 is increased, the core-cut probiotic sanitary napkin 100 will be too soft and can be displaced or even leak, so the slits 121 in the peripheral region 123 around the central region 122 have a relatively small cross-sectional area to ensure that the core-cut probiotic sanitary napkin 100 has a certain strength and softness.
[0064] The different cross-sectional areas of the slits 121 in the central region 122 and the peripheral region 123 of the absorbent core layer 120 can be stacked on the basis of any of the above embodiments according to actual needs.
[0065] The cross-sectional area of the individual slits 121 in the central region 122 being greater than or equal to the cross-sectional area of the individual slits 121 in the peripheral region 123 includes but is not limited to the following cases:
[0066] 1) The lengths of all the slits 121 are the same, but the widths of the slits 121 in the central region 122 are greater than the widths of the slits 121 in the peripheral region 123, as shown in Figure 5 ;
[0067] 2) The widths of all the slits 121 are the same, but the lengths of the slits 121 in the central region 122 are greater than the lengths of the slits 121 in the peripheral region 123;
[0068] 3) The lengths and widths of the slits 121 in the central region 122 are greater than the lengths and widths of the slits 121 in the peripheral region 123.
[0069] 4) the cross-sectional area of all slits 121 in the central region 122 is greater than the cross-sectional area of the slits 121 in the edge region 123;
[0070] 5) the cross-sectional area of some slits 121 in the central region 122 is greater than the cross-sectional area of the slits 121 in the edge region 123, and the cross-sectional area of some slits 121 in the central region 122 is equal to the cross-sectional area of the slits 121 in the edge region 123, as shown in Figure 6 .
[0071] The above five cases can occur alone or in combination in the same core-cut probiotic sanitary napkin 100 product, as long as the cross-sectional area of the individual slits 121 in the central region 122 is greater than or equal to the cross-sectional area of the individual slits 121 in the edge region 123.
[0072] Referring to Figure 7 , as some preferred embodiments, the slits 121 in the edge region 123 are inclined. By inclining the slits 121 in the edge region 123, the path of the menstrual blood is increased when it seeps down, so the path of the menstrual blood is also lengthened, which can effectively prevent the occurrence of menstrual blood backflow and is conducive to keeping the surface of the core-cut probiotic sanitary napkin 100 dry.
[0073] Optionally, the slits 121 in the edge region 123 are inclined toward the central region 122 along the side close to the leakage-proof layer 130. Thus, the menstrual blood can converge in the middle after being diverted by the slits 121 in the edge region 123, thereby avoiding side leakage of the menstrual blood.
[0074] Optionally, the acute angle a between the slits 121 in the edge region 123 and the use contact surface of the core-cut probiotic sanitary napkin 100 is 30-60°. By controlling the angle a within the above range, the diversion rate of the menstrual blood can be improved, menstrual blood leakage can be prevented, and the hardness and softness of the core-cut probiotic sanitary napkin 100 can be ensured.
[0075] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously modified and changed. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
