Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanitary napkin technology, and more specifically, to a probiotic sanitary napkin. Background Technology
[0002] There are many types of sanitary napkins available, including a significant number containing probiotics. Probiotic loading on sanitary napkins effectively inhibits the growth of harmful bacteria, benefiting women's health. When the probiotic load in a sanitary napkin reaches a certain level, it can effectively suppress the growth of harmful bacteria. Therefore, ensuring an appropriate amount of probiotics on sanitary napkins is one of the current research directions. Among the currently disclosed technologies, one approach involves directly placing a probiotic layer on the surface fiber layer of the sanitary napkin to achieve the purpose of loading probiotics. The advantage of this method is that it can load more probiotics, but the disadvantage is that the probiotic layer or the probiotic particles within it are prone to detachment during the sanitary napkin manufacturing process.
[0003] In view of this, this utility model is proposed. Utility Model Content
[0004] 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.
[0005] The embodiments of this utility model can be implemented as follows:
[0006] The probiotic sanitary napkin provided in this embodiment includes a sanitary napkin body, which has a surface layer disposed on one side for introducing menstrual blood and a bottom film disposed on the other side for adhering to underwear.
[0007] The surface layer consists of a fiber layer, an adhesive layer, and a probiotic layer arranged sequentially from the inside to the outside of the sanitary napkin.
[0008] In an optional embodiment, the adhesive layer is a polyurethane layer, a polyvinyl chloride resin layer, or a modified polypropylene resin layer.
[0009] In an optional implementation, the probiotic layer consists of layers of microparticles;
[0010] The microparticles are probiotic powder or powder obtained after drying probiotic fermentation filtrate.
[0011] In an optional embodiment, the ratio of the thickness of the probiotic layer to the thickness of the adhesive layer is 1:1 to 4.
[0012] In an optional embodiment, the ratio of the sum of the thicknesses of the probiotic layer and the adhesive layer to the thickness of the fiber layer is 1:10 to 30.
[0013] In an optional embodiment, the fiber layer is a fiber cloth containing probiotics.
[0014] In an optional embodiment, the composite layer consisting of the adhesive layer and the probiotic layer completely or partially covers the fiber layer.
[0015] In an optional embodiment, the composite layer covers 50% to 80% of the area of the fiber layer.
[0016] In an optional implementation, a probiotic protective layer is also provided above the probiotic layer.
[0017] In an optional implementation, the probiotic protective layer is an L-ascorbic acid layer.
[0018] The beneficial effects of the probiotic sanitary napkin provided in this embodiment of the invention include:
[0019] By placing the probiotic layer on the outermost surface, the probiotics can more easily migrate to the vaginal epidermis during the friction of the sanitary napkin surface against the skin, affecting the vaginal flora environment and pH value, thereby better inhibiting the growth of harmful bacteria and thus being more beneficial to human health. By setting an adhesive layer to adhere the probiotic layer to the surface of the sanitary napkin, the probiotics can be stably applied to the sanitary napkin product, improving the problem of probiotics easily falling off during the sanitary napkin production process.

[0030] First Embodiment
[0031] like Figure 1 As shown, the present invention provides a probiotic sanitary napkin 100, which includes a sanitary napkin 100 body. The sanitary napkin 100 body has a surface layer 120 disposed on one side for introducing menstrual blood and a bottom film 110 disposed on the other side for bonding with underwear. The surface layer 120 includes a fiber layer 121, an adhesive layer 122 and a probiotic layer 123 disposed sequentially from the inside to the outside of the sanitary napkin 100.
[0032] The sanitary napkin 100 provided by this utility model has a probiotic layer 123 on its outermost surface. During the process of rubbing the skin with the surface layer 120 of the sanitary napkin 100, the probiotics can more easily migrate to the vaginal epidermis, affecting the flora environment and pH value of the vulva, thereby better inhibiting the growth of harmful bacteria and thus being more beneficial to human health. By setting an adhesive layer 122 to adhere the probiotic layer 123 to the surface of the sanitary napkin 100, the probiotics can be stably applied in the sanitary napkin 100 product, improving the problem of probiotics being easily detached during the production process of the sanitary napkin 100.
[0033] Preferably, the adhesive layer 122 is a polyurethane layer, a polyvinyl chloride resin layer, or a modified polypropylene resin layer.
[0034] Choosing food-grade material as the adhesive layer 122 can prevent the sanitary napkin 100 from irritating the skin when it comes into contact with the body.
[0035] Furthermore, the probiotic layer 123 is composed of stacked microparticles; the microparticles are probiotic powder particles or powder particles obtained after drying probiotic fermentation filtrate.
[0036] The probiotic layer 123 can be formed, for example, by spraying probiotic powder onto the surface of the adhesive layer 122, which then adheres firmly under the adhesive force of the adhesive layer 122 to form the probiotic layer 123; or by spraying probiotic fermentation filtrate onto the surface of the adhesive layer 122, and then drying or air-drying the filtrate to form the probiotic layer 123.
[0037] Optionally, to ensure better comfort of the sanitary napkin 100 and to ensure good adhesion between the adhesive layer 122 and the probiotic layer 123, the ratio of the thickness of the probiotic layer 123 to the thickness of the adhesive layer 122 is 1:1 to 4.
[0038] Optionally, to further improve the comfort of the sanitary napkin 100, the ratio of the sum of the thicknesses of the probiotic layer 123 and the adhesive layer 122 to the thickness of the fiber layer 121 is 1:10 to 30.
[0039] Optionally, the composite layer consisting of the adhesive layer 122 and the probiotic layer 123 completely covers the fiber layer 121.
[0040] Preferably, a probiotic protective layer 124 is provided above the probiotic layer 123; the probiotic protective layer 124 is an L-ascorbic acid layer.
[0041] The L-ascorbic acid layer is located on the outermost layer. If particle shedding occurs, the L-ascorbic acid particles will detach first, rather than the probiotic particles in the probiotic layer 123, thus protecting the probiotic layer 123. Furthermore, the L-ascorbic acid layer is slightly acidic, effectively inhibiting the growth of harmful bacteria on the sanitary napkin. It should be noted that the probiotic protective layer 124 is very thin. During use of the sanitary napkin 100, the L-ascorbic acid dissolves in liquid conditions, allowing the probiotic layer 123 to communicate with the outside environment, and does not hinder the migration of probiotics towards the vulva.
[0042] Furthermore, acidic substances, such as food-grade acidifiers like L-ascorbic acid, can be added to the probiotic protective layer 124 to make the sanitary napkin 100 slightly acidic, in order to inhibit the growth of harmful bacteria as much as possible.
[0043] Furthermore, an absorbent core 130 is provided between the surface layer 120 and the bottom membrane 110 to absorb the discharged menstrual blood.
[0044] It should be noted that, in order to make the structure of the sanitary napkin 100 provided in the various embodiments of this utility model clear, each layer appears to be thicker in the accompanying drawings, but is actually thinner. The thickness of the adhesive layer 122, the probiotic layer 123, and the probiotic protective layer 124 is all within 10-100 nm.
[0045] Second Embodiment
[0046] This embodiment is basically the same as the first embodiment, except that:
[0047] In this embodiment, the fiber layer 121 is a fiber cloth containing probiotics.
[0048] Probiotic-containing fabric is an existing technology, which involves mixing probiotic powder or probiotic fermentation filtrate with fibers during the manufacturing process. The presence of probiotics in the fabric increases the overall probiotic content in the sanitary napkin, better ensuring a balanced flora in the genital area and inhibiting the growth of harmful bacteria.
[0049] Optionally, such as Figure 2 As shown, the composite layer consisting of adhesive layer 122 and probiotic layer 123 partially covers fiber layer 121. When fiber layer 121 is a fiber cloth containing probiotics, the composite layer consisting of adhesive layer 122 and probiotic layer 123 partially covers fiber layer 121 to ensure that the probiotics in fiber layer 121 can migrate unimpeded to the surface of sanitary napkin 100 or around the vulva.
[0050] It should be noted that, Figure 2 This is only one example of the composite layer of this invention not fully covering the fiber layer. In other embodiments, the composite layer may be distributed in multiple points on the fiber layer 121.
[0051] Optionally, the composite layer covers 50% to 80% of the area of the fiber layer 121, for example, 50%, 60%, 70% or 80%.
[0052] In summary, the sanitary napkin 100 provided by this utility model has a probiotic layer 123 on its outermost surface. During the process of rubbing the skin with the surface layer 120 of the sanitary napkin 100, the probiotics can more easily migrate to the vaginal epidermis, affecting the vaginal flora environment and pH value, thereby better inhibiting the growth of harmful bacteria and thus being more beneficial to human health. By setting an adhesive layer 122 to adhere the probiotic layer 123 to the surface of the sanitary napkin 100, the probiotics can be stably applied in the sanitary napkin 100 product, improving the problem of probiotics easily falling off during the production process of the sanitary napkin 100.
[0053] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations 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.
