Abstract
Description
Technical Field
[0001] The present application relates to a sanitary napkin, and more particularly to a one-piece surface layer sanitary napkin. Background Art
[0002] There are three types of sanitary napkins on the market. The first type is a hydrophilic surface layer in the middle of the surface layer, with leakage prevention edges on both sides of the hydrophilic surface layer. The second type is a hydrophilic surface layer in the middle of the surface layer, with leakage prevention edges on both sides of the hydrophilic surface layer folded back to the inside of the hydrophilic surface layer. The third type is a hydrophilic surface layer that is integrated throughout the surface of the sanitary napkin.
[0003] Most sanitary napkins on the market use the first type of structure, and a few use the second and third types of structures. Since the hydrophilic surface layer and the leak-proof side edge of the first type of structure need to overlap by 5mm-15mm, the material cost will increase compared to the third type of structure, especially when the hydrophilic surface layer and the leak-proof side edge are both made of pure cotton, the cost will increase significantly;
[0004] For the second type of structural products, since the hydrophilic surface layer and the leak-proof partition need to overlap and overlap to the lateral inner side of the hydrophilic surface layer, this structure requires an additional layer of waterproof material on the waterproof base layer, which increases the cost even more.
[0005] Since the third type of structural products have an integrated hydrophilic surface layer, the two side parts and the middle part have a hydrophilic effect, so side leakage is likely to occur during use.
[0006] To this end, the present application provides a low-cost, one-piece surface-layer sanitary napkin that prevents side leakage. Utility Model Content
[0007] In order to overcome the deficiencies of the prior art, the one-piece surface layer sanitary napkin described in the present application adopts an one-piece surface layer, and the wings on both sides are treated to have a water-repellent effect, with low production cost and no side leakage.
[0008] The technical solution adopted by this application to solve its technical problem is:
[0009] A one-piece surface sanitary napkin comprises a sanitary napkin body, wherein the sanitary napkin body comprises an one-piece surface layer, an absorbent core layer and a waterproof layer arranged in sequence from top to bottom, wherein the one-piece surface layer is arranged in the transverse direction as a first section surface layer, a second section surface layer and a third section surface layer, and the first section surface layer, the second section surface layer and the third section surface layer have different hydrophilicities.
[0010] Furthermore, the transverse distance of the first section of the surface layer is 50-70 mm, the transverse distance of the second section of the surface layer is 50-80 mm, and the transverse distance of the third section of the surface layer is 50-70 mm.
[0011] Furthermore, the first surface layer, the second surface layer and the third surface layer are treated by dipping, spraying or transfer.
[0012] Furthermore, a guide layer is provided between the integrated surface layer and the absorbent core layer.
[0013] Furthermore, a release paper is provided on the lower surface of the waterproof layer.
[0014] Furthermore, wings are provided on both sides of the sanitary napkin body.
[0015] Furthermore, the waterproof layer is a breathable PE film or non-woven fabric.
[0016] Furthermore, the wings are water-repellent wings.
[0017] Furthermore, the material of the integrated surface layer is pure cotton.
[0018] Furthermore, the second section of the surface layer is located in the middle of the integrated surface layer, and the first section of the surface layer and the third section of the surface layer are located on both sides of the second section of the surface layer.
[0019] The beneficial effects of this application are:
[0020] 1. The sanitary napkin described in the utility model adopts an integrated surface structure, which is arranged as three sections of surface layers with different hydrophilicities, and the wings on both sides are treated to have a water-repellent effect, which not only solves the high cost problem existing in the first type of wing structure, but also solves the problem of the third type of integrated structure in which the two sides are as hydrophilic as the middle surface layer and are more prone to side leakage.
[0021] 2. The sanitary napkin described in the present application avoids the overlap of the hydrophilic surface layer and the anti-leakage partition edge through an integrated surface layer design, reduces the use of materials, and reduces production costs; the anti-leakage ability of the sanitary napkin is enhanced by treating the wings to have a water-repellent effect to prevent side leakage: the integrated surface layer made of pure cotton material increases the skin-friendliness and comfort of the product, thereby improving the comfort level.

[0027] The following will clearly and completely describe the concept, specific structure and technical effects of the present application in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present application. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features created in this application can be combined interactively without conflicting with each other.
[0028] like Figure 1 As shown, an integrated surface sanitary napkin includes a sanitary napkin body 1, wherein the sanitary napkin body 1 includes an integrated surface layer 11, an absorbent core layer 12 and a waterproof layer 13 arranged in sequence from top to bottom, wherein the integrated surface layer 11 is arranged in the transverse direction as a first surface layer 111, a second surface layer 112 and a third surface layer 113, and the hydrophilicity of the first surface layer 111, the second surface layer 112 and the third surface layer 113 are different.
[0029] As an improved solution, Figure 2 The transverse distance (Z) of the first surface layer 111 is 50-70 mm, the transverse distance (Y) of the second surface layer 112 is 50-80 mm, and the transverse distance (X) of the third surface layer 113 is 50-70 mm.
[0030] Specifically, the lateral distances of the first section surface layer, the second section surface layer and the third section surface layer are set to a specific range in order to achieve absorption and diversion effects in different areas. The lateral distances of the first section and the third section surface layer are 50 to 70 mm, and they are designed for both sides of the main absorption area to provide auxiliary absorption and prevent side leakage. The lateral distance of the second section surface layer is slightly wider, 50 to 80 mm, and it is located in the center of the sanitary napkin, which is the main absorption area. These dimensions can be adjusted according to actual absorption needs to optimize product performance. Therefore, in the present application, the first section surface layer, the second section surface layer and the third section surface layer are set with different lateral distances and different hydrophilicities in order to achieve surface layers with different hydrophilicities. This design can better control the distribution and absorption of liquid, thereby improving the absorption performance and leakage prevention effect of the sanitary napkin.
[0031] As an improved solution, the first surface layer 111, the second surface layer 112 and the third surface layer 113 are treated by dipping, spraying or transfer.
[0032] Specifically, the first surface layer, the second surface layer and the third surface layer are treated by dipping, spraying or transfer, which can change the hydrophilicity or water repellency of the surface layer. Dipping treatment involves immersing the surface material in a specific chemical solution to change its water absorption capacity. Spraying treatment is used to form a film with specific properties on the surface layer. Transfer treatment involves transferring a specific pattern or property to the surface layer. The selection and application of these treatment methods can be customized according to the specific requirements and intended use of the product.
[0033] More specifically, the second surface layer is immersed in a hydrophilic finishing agent with a mass concentration of 1-4%, and the first surface layer and the third surface layer are immersed in a hydrophilic finishing agent with a mass concentration of 6-8%, thereby forming a second surface layer with a hydrophilicity lower than that of the first surface layer and the third surface layer, and the first surface layer and the third surface layer with high hydrophilicity are located on both sides to more easily absorb and guide the liquid.
[0034] Therefore, in the present application, the purpose of the dipping, spraying or transfer treatment is to increase the hydrophilicity or water repellency of the surface layer. This treatment can improve the absorption and conduction of liquids, thereby improving the use effect and comfort of the sanitary napkin.
[0035] As an improved solution, a guide layer 14 is provided between the integrated surface layer 11 and the absorbent core layer 12. The guide layer is provided between the integrated surface layer and the absorbent core layer to promote uniform distribution of liquid from the surface layer to the absorbent core layer, prevent liquid from accumulating on the surface layer, reduce the risk of side leakage, and improve absorption efficiency. The material selection and structural design of the guide layer can be specifically selected according to the flow characteristics of the liquid and the absorption capacity of the absorbent core layer.
[0036] Therefore, in the present application, the purpose of providing a guide layer is to more effectively transfer the liquid from the surface layer to the absorbent core layer, which can improve the absorption efficiency of the sanitary napkin, prevent liquid from accumulating on the surface layer, and reduce the possibility of side leakage.
[0037] As an improved solution, a release paper 15 is provided on the lower surface of the waterproof layer 13. Specifically, the release paper is provided on the lower surface of the waterproof layer, and the release paper is used to protect the lower surface of the product from contamination or damage, and facilitate the processing and packaging of the product. The release paper is usually easy to peel off, and the user can easily remove it when using the sanitary napkin to expose the waterproof layer below.
[0038] Therefore, in the present application, the purpose of providing the release paper is to protect the surface of the sanitary napkin from being contaminated before use, and also to facilitate the user to peel it off during use, thereby improving the convenience of use.
[0039] As an improved solution, Figure 3 As shown, wings 2 are provided on both sides of the sanitary napkin body 1. Specifically, wings are provided on both sides of the sanitary napkin body, and the wings are designed to improve the fixation and adaptability of the sanitary napkin, so that it can better fit the shape of the user's lower body and prevent displacement or side leakage during activities. The material, shape and size of the wings can be designed according to the different needs of the user. Therefore, in the present application, the purpose of setting the wings is to enhance the fixation and anti-side leakage ability of the sanitary napkin, and the wings can better fit the body curve and reduce the risk of side leakage during activities.
[0040] As an improved solution, the waterproof layer 13 is a breathable PE film or non-woven fabric. Specifically, the waterproof layer is made of a breathable PE film or non-woven fabric. Both materials have good waterproof properties. The breathable PE film provides air permeability, which helps to reduce the accumulation of moisture and improve the comfort of the user; while the non-woven fabric provides better strength and durability due to its structural characteristics. In the present application, the purpose of setting a breathable PE film or non-woven fabric as a waterproof layer is to prevent liquid leakage while maintaining the air permeability of the sanitary napkin, which can reduce the accumulation of moisture and heat and improve the comfort of the user.
[0041] As an improved solution, the wings 2 are water-repellent wings 2. Specifically, the wings are water-repellent wings, which means that the material and surface treatment of the wings have water-repellent properties, which can prevent liquid from leaking along the edges of the wings and enhance the anti-leakage effect. The material selection and surface treatment technology of the water-repellent wings can be carried out according to the requirements of water-repellent performance.
[0042] Therefore, in the present application, the purpose of providing water-repellent wings is to form a leak-proof barrier on both sides of the sanitary napkin, and through the characteristics of the water-repellent material, side leakage is effectively prevented to improve the safety of the sanitary napkin.
[0043] As an improved solution, the material of the integrated surface layer 11 is pure cotton. Specifically, the material of the integrated surface layer is pure cotton, which is widely used as the surface layer of sanitary napkins because of its natural, soft, skin-friendly and high water absorption. The use of pure cotton material can provide a more comfortable user experience, especially for users with sensitive skin.
[0044] Therefore, in this application, the purpose of choosing pure cotton as the one-piece surface material is to provide better skin-friendliness and comfort. Pure cotton material is usually softer and more breathable, and is suitable for sensitive skin.
[0045] As an improved solution, the second section surface layer 112 is located in the middle of the integrated surface layer 11, and the first section surface layer 111 and the third section surface layer 113 are located on both sides of the second section surface layer 112. Therefore, in the present application, the purpose of placing the second section surface layer in the middle and the first section and the third section surface layer on both sides is to achieve better liquid distribution and absorption through the design of different hydrophilicity. The surface layer in the middle has a higher hydrophilicity and is used for the main absorption area, while the surface layers on both sides have a lower hydrophilicity and are used to prevent side leakage. This design can improve the overall performance and use effect of the sanitary napkin.
[0046] The above is a specific description of the preferred implementation of the present application, but the invention of the present application is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent modifications or substitutions without violating the spirit of the present application. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
