Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanitary napkin technology, specifically to a skin-care sanitary napkin. Background Technology
[0002] As people's living standards improve, more and more consumers are paying attention to the additional functions of products. Traditional sanitary napkins generally suffer from crude methods of adding skin care ingredients: pre-impregnated non-woven fabrics cause skin care liquids (such as aloe vera and vitamin E) to be wasted in non-contact areas (about 45% of the material area), increasing costs; side leakage risk: excess skin care ingredients on both sides can easily migrate to the leak-proof edge, destroying its hydrophobicity and causing side leakage (clinical feedback accounts for more than 30%); active ingredient deterioration: the degradation rate of active ingredients in pre-made materials during storage reaches 15%-40%, shortening the product's shelf life. Utility Model Content
[0003] Therefore, in order to address the above problems, this utility model provides a skin care sanitary napkin that solves the problems of waste of skin care liquid, side leakage and short shelf life caused by design defects in existing skin care sanitary napkins.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0005] A skin-care sanitary napkin includes a sanitary napkin body, which comprises a top layer, a diversion layer, an absorbent core, and a bottom layer stacked sequentially from top to bottom. The length direction of the sanitary napkin body is defined as longitudinal, and the width direction as transverse. The sanitary napkin body has a skin-friendly area, a gap area, and a leak-proof side. The leak-proof side is located on both sides of the skin-friendly area, and the gap area is located between the skin-friendly area and the leak-proof side. The skin-friendly area has a skin-care coating, which is located on the upper surface of at least one of the structural layers of the top layer, the diversion layer, and the absorbent core. When the skin-care coating has two or more layers, the coverage area of the lower skin-care coating is smaller than the coverage area of the upper skin-care coating.
[0006] Furthermore, the skin care coating is provided only on the upper surface of the surface layer, and the thickness of the skin care coating in the middle is greater than the thickness on both sides.
[0007] Furthermore, the skin-care coating on the upper surface of the surface layer is applied at least twice, with the lateral width of each application gradually decreasing to create a gradient change in the thickness of the skin-care coating.
[0008] Furthermore, the skin care coating is only provided on the surface layer and the upper surface of the guide layer, and the lateral width of the skin care coating on the guide layer is smaller than the width of the skin care coating on the surface layer.
[0009] Furthermore, the longitudinal length of the skin-care coating on the guide layer is less than the longitudinal length of the skin-care coating on the surface layer.
[0010] Furthermore, the skin care coating is provided on the upper surface of the surface layer, the flow guiding layer, and the absorbent core, and the skin care coating located below has a smaller horizontal width and a smaller vertical length than the skin care coating located above.
[0011] Furthermore, the lateral width of the interval is 3-5 mm.
[0012] Furthermore, the lateral width of the skin-friendly area is 60-100mm.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention solves the industry problem of skin care ingredient contamination and leakage prevention layers by using a skin care coating formed by spraying with a physical interval zone and an instant-drying hydrogel formula. The skin care coating position is precisely defined by the skin-friendly zone to eliminate edge waste. The multi-layer coating area decreasing design further reduces the amount of material soaked in the bottom layer. The layered coating design reduces the contact area between the skin care layer and the air. The large upper coating area takes effect quickly, while the small lower coating area provides slow-release replenishment. Compared with liquid pre-impregnation, the solid coating isolates oxygen penetration. Attached Figure Description

[0024] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0025] Example:
[0026] like Figures 1 to 3 As shown, a skin-care sanitary napkin includes a sanitary napkin body 1. The sanitary napkin body 1 includes a top layer 2, a diversion layer 3, an absorbent core 4, and a bottom layer 5, which are stacked sequentially from top to bottom. The length direction of the sanitary napkin body 1 is defined as longitudinal, and the width direction is defined as transverse. The sanitary napkin body 1 is provided with a skin-friendly area 11, a spacing area 12, and a leak-proof side 13. The leak-proof side 13 is located on both sides of the skin-friendly area 11, and the spacing area 12 is located between the skin-friendly area 11 and the leak-proof side 13. The skin-friendly area 11 is provided with a skin-care coating 111. The skin-care coating 111 is provided on the upper surface of at least one of the structural layers of the top layer 2, the diversion layer 3, and the absorbent core 4. When the skin-care coating 111 has two or more layers, the coverage area of the skin-care coating 111 located below is smaller than the coverage area of the skin-care coating 111 located above.
[0027] In this embodiment, only the upper surface of the surface layer 2 is provided with a skin care coating 111, and the thickness of the skin care coating 111 in the middle is greater than the thickness on both sides; the skin care coating 111 on the upper surface of the surface layer 2 is sprayed twice, and the lateral width of each spray gradually decreases to form a gradient change in the thickness of the skin care coating 111. The lateral width of the skin-friendly area 11 is 80mm, the lateral width of the skin care coating 111 sprayed for the first time is 80mm, and the lateral width of the skin care coating 111 sprayed for the second time is 60mm; the lateral width of the interval area is 3mm.
[0028] In other preferred embodiments, only the surface layer 2 and the upper surface of the guide layer 3 are provided with a skin care coating 111. The lateral width of the skin care coating 111 on the guide layer 3 is smaller than the width of the skin care coating 111 on the surface layer 2, and the longitudinal length of the skin care coating 111 on the guide layer 3 is smaller than the longitudinal length of the skin care coating 111 on the surface layer 2.
[0029] In other preferred embodiments, the skin care coating 111 is provided on the upper surface of the surface layer 2, the flow guiding layer 3, and the absorbent core 4, and the skin care coating 111 located below has a smaller lateral width and longitudinal length than the skin care coating 111 located above.
[0030] The skin care coating 111, formed by spraying with a physical interval zone and an instant-drying hydrogel formula, solves the industry problem of skin care ingredient contamination and leakage prevention layer. The skin-friendly zone 11 precisely defines the position of the skin care coating 111, eliminating edge waste. The multi-layer coating area decreasing design further reduces the amount of material soaked in the bottom layer. The layered coating design reduces the contact area between the skin care layer and the air. The large upper coating area takes effect quickly, while the small lower coating area provides slow release and replenishment. Compared with liquid pre-impregnation, the solid coating isolates oxygen penetration.
[0031] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
