Abstract
Description
Technical Field
[0001] This utility model relates to the field of women's products technology, and more specifically, to a probiotic sanitary napkin. Background Technology
[0002] Traditional sanitary napkins consist of three layers stacked from top to bottom: a distribution layer (or top layer), an absorbent layer (containing an absorbent chip), and a leak-proof layer. As shown in the diagram, the top layer and leak-proof layer generally overlap by the same size, covering the largest area; the absorbent layer covers a relatively smaller area, and the absorbent chip covers the smallest area. Sanitary napkins are also typically divided into a front section, a middle section, and a back section. During use, the middle section usually faces the vaginal opening and is the main area for receiving and absorbing menstrual blood; the front section corresponds to the mons pubis area; and the back section corresponds to the anus.
[0003] With the advancement of modern technology in the study of probiotics for women, the applicant has begun to explore the application of probiotics in sanitary napkins, enabling them to exert their effects during use. Specifically, this could involve regulating the pH level of the female genital area through the metabolites of probiotics, or through friction and contact with human skin, allowing them to colonize the skin and compete with harmful bacteria, thus preventing their survival and reproduction.
[0004] Designing the structure of sanitary napkins to ensure that probiotics can more effectively improve the vaginal environment during menstruation is a current research focus. Therefore, this invention is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a probiotic sanitary napkin that aims to improve at least one of the problems mentioned in the background art.

[0035] like Figure 2 As shown, current probiotic sanitary napkins 100 generally add probiotics to the surface layer 110. Specifically, the fibers with added probiotics are usually made into non-woven fabric, and then this non-woven fabric is used as the material of the surface layer 110.
[0036] On the one hand, while existing technologies incorporate probiotics, the amount added needs to be controlled to meet the flow requirements of the surface layer 110. On the other hand, probiotic colonization relies on contact and friction with human skin. During sanitary napkin use, the contact and friction between different areas of the sanitary napkin and the human skin vary. To address this, the inventors propose a zoned probiotic sanitary napkin 100 based on the different functions of different parts of the sanitary napkin.
[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0040] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0041] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0042] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0043] like Figure 1 As shown, this utility model provides a probiotic sanitary napkin 100, including a central area 101 corresponding to the vaginal opening and other non-central areas;
[0044] Other non-central areas contain probiotic zones.
[0045] A probiotic zone refers to an area containing probiotics.
[0046] Since the central area 101 corresponding to the vaginal opening mainly needs to receive and absorb menstrual blood, and considering the drainage needs of the middle part b, the amount of probiotics added should not be too much. Thus, the effect of probiotics placed in the area corresponding to the vaginal opening is limited. The probiotic sanitary napkin 100 provided by this utility model only sets probiotic areas in the non-central area 101. By placing probiotics in these areas, it is not limited by the drainage needs, and a larger amount of probiotics can be added, thereby better improving the vaginal environment during menstruation and better protecting women's health.
[0047] Specifically, the probiotic sanitary napkin 100 includes a surface layer 110, an absorbent layer 120, and a bottom layer 130. The surface layer 110 has a larger area than the absorbent layer 120, and the absorbent layer 120 is sandwiched between the surface layer 110 and the bottom layer 130. Further, an absorbent core 121 is provided in the middle b of the absorbent layer 120.
[0048] Specifically, along the length of the sanitary napkin, it is divided into a front part a, a middle part b, and a back part c, with the central area 101 corresponding to the vaginal opening located in the middle part b.
[0049] The probiotic area can be located within the corresponding surface layer 110 and at the front a.
[0050] The probiotic area can be located within the corresponding surface layer 110 and at the rear c.
[0051] The probiotic area can be the area remaining after removing the absorption layer 120 from the corresponding surface layer 110.
[0052] The range of the probiotic area can be the area remaining after removing the absorption layer 120 from the corresponding surface layer 110 range, and it is located in the front part a.
[0053] The range of the probiotic area can be the area remaining after removing the absorption layer 120 from the corresponding surface layer 110 range, and it is located at the rear c.
[0054] The range of the probiotic area can be the area remaining after removing the range of the absorption core 121 from the range of the corresponding surface layer 110.
[0055] The probiotic area can be the area remaining after removing the absorption core 121 area from the corresponding surface layer 110 area, and it is located in the front part a.
[0056] The range of the probiotic area can be the area remaining after removing the range of the absorption core 121 from the range of the corresponding surface layer 110, and it is located at the rear c.
[0057] Optionally, the probiotic region is at least a portion of the surface layer 110. For example, a portion of the surface layer 110 is loaded with probiotics.
[0058] Furthermore, the probiotic zone can be formed by applying a liquid or powder mixture containing probiotics onto the surface layer 110 through spraying, coating, or other methods.
[0059] Furthermore, such as Figures 3 to 7 As shown, the probiotic area includes a probiotic pad 140, which is disposed at the edge of the non-absorbent layer 120 between the top layer 110 and the bottom layer 130.
[0060] According to user feedback, the edges of sanitary napkins are thinner and easier to fold. Also, because the middle of the sanitary napkin is thicker than the edges, it can cause a feeling of foreign body when used. Therefore, placing a probiotic pad 140 at the edge can increase the thickness in this area and improve the problems of easy folding and foreign body sensation.
[0061] Optionally, the probiotic pad 140 includes a nonwoven fabric substrate and probiotic particles loaded on the nonwoven fabric substrate. It can be manufactured from a nonwoven fabric containing probiotics.
[0062] In other embodiments of this utility model, the probiotic pad 140 may also be formed from a material that has been sprayed, coated, or soaked in a liquid containing probiotics.
[0063] Since probiotics are usually introduced into the vulvar environment through friction between human skin and sanitary napkins, placing probiotic pads 140 in areas prone to friction can achieve better results.
[0064] Optionally, such as Figure 3 As shown, other non-central areas include the two side areas located at the rear (c), corresponding to the groin area of the human thigh during use. These side areas are located at the edges of the sanitary napkin, and each side area has a probiotic pad 140 with a corresponding shape. The groin area of the human thigh experiences strong friction with the sanitary napkin, so placing the probiotic pad 140 in this corresponding position provides better protection.
[0065] It should be noted that in other embodiments of this utility model, the shape of the probiotic pad 140 does not necessarily need to correspond exactly to the two sides. Any shape that is approximately corresponding and provides better comfort during use is acceptable.
[0066] Optionally, such as Figure 4 and Figure 5As shown, a probiotic pad 140, corresponding to the shape of the edge, is provided at the rear part c, the edge furthest from the front part a. Since the tail of the sanitary napkin is easy to fold, the probiotic pad 140 placed here allows for better friction with the body after folding, resulting in a more effective effect.
[0067] It should be noted that in other embodiments of this utility model, the shape of the probiotic pad 140 does not necessarily need to correspond exactly to the tail edge; any shape that is approximately corresponding and provides better comfort during use is acceptable.
[0068] Optionally, such as Figure 6 and Figure 7 As shown, a probiotic pad 140 corresponding to the shape of the edge is provided at the edge of the front part a furthest from the rear part c. The front edge of the sanitary napkin is also easy to fold, and the probiotic pad 140 is placed here so that it can easily rub against the human body after folding, thus achieving a better effect.
[0069] It should be noted that in other embodiments of this utility model, the shape of the probiotic pad 140 does not necessarily need to correspond exactly to the edge of the front part a. Any shape that is approximately corresponding and provides better comfort during use is acceptable.
[0070] Optionally, the probiotic area located at the rear (c) may come into contact with or be close to the anus. The probiotics in the probiotic area may include Bifidobacterium lactis, which may reach the area near the anus or enter the anus through friction, thus improving the intestinal flora environment to some extent.
[0071] Optionally, the probiotic area in the anterior part a may contact or be close to the mons pubis of the human body, and the probiotics in the probiotic area may be anti-allergic probiotics, such as Bifidobacterium longum.
[0072] In summary, the probiotics provided in this embodiment of the present invention are only placed in the non-central area 101. By placing probiotics in these areas, the flow requirements are not limited, and a larger amount of probiotics can be added, thereby better improving the vaginal environment during menstruation and better protecting women's health.
[0073] In a preferred embodiment, the probiotic pad 140 is provided at the edge to further improve the environment around the female vulva and prevent the edge from folding over, thereby further improving the user experience.
[0074] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
