Description

Technical Field

[0001] This utility model relates to a wave-shaped protective pad. Background Technology

[0002] Panty liners are a type of feminine hygiene product, primarily used to absorb daily secretions and keep the intimate area dry.

[0003] Panty liners mainly consist of a top layer, an absorbent layer, and a bottom layer.

[0004] Surface layer: Usually made of cotton or non-woven fabric, soft and skin-friendly.

[0005] Absorbent layer: High molecular weight absorbent material that quickly absorbs and locks in the liquid.

[0006] Bottom layer: Waterproof material to prevent leakage.

[0007] Current panty liners fit snugly against the vulva. In summer, due to increased sweating, the tight fit of the panty liner can lead to poor ventilation, causing excessive sweating and bacterial growth.

[0008] Based on the above problems, we designed a wave-shaped pad that can reduce the contact area and increase breathability. Utility Model Content

[0009] The technical problem to be solved by this utility model is to provide a wave-shaped protective pad that can reduce the contact area and increase breathability.

[0010] To solve the above problems, the present invention adopts the following technical solution:

[0011] A wave-shaped pad includes a bottom layer, a top layer, a flow-guiding layer, and an absorbent core. The absorbent core is wrapped between the bottom layer and the top layer, and the edge of the absorbent core is fixed to the bottom layer and the top layer. The flow-guiding layer covers the surface of the absorbent core. A skin-friendly layer is fixed to the surface of the top layer, and an exposure groove is provided in the middle of the skin-friendly layer, with a portion of the top layer exposed in the exposure groove.

[0012] Preferably, the thickness of the skin-friendly layer is 0.5 mm to 1.2 mm.

[0013] Preferably, the surface layer is a non-woven fabric layer.

[0014] Preferably, the skin-friendly layer is made of pure cotton.

[0015] Preferably, the inner walls on both sides of the exposure groove are wavy inner walls.

[0016] Preferably, on the surface of the outer layer, a vertically penetrating rapid permeation hole is formed at the low point position corresponding to the corrugated inner wall.

[0017] Preferably, the surface of the flow guiding layer is machined with through holes corresponding to the rapid permeation holes.

[0018] Preferably, the absorbent core includes an outer shell and polymer absorbent particles filled inside the outer shell, the outer shell being a non-woven fabric.

[0019] The beneficial effects of this utility model are:

[0020] This product uses a skin-friendly layer that comes into contact with the skin of the vulva. The contact area is relatively small and exposes the vaginal opening. A tiny gap is maintained between the vaginal opening and the surface layer, which does not affect the absorption of secretions and menstrual blood. At the same time, it increases breathability, making the product drier and more comfortable to use. It is suitable for widespread use. Attached Figure Description

[0026] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0027] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0028] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. 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. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, in the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] See Figure 1 The wave-shaped pad shown includes a bottom layer 1, a top layer 2, a flow-guiding layer 3, and an absorbent core 4. The absorbent core 4 is wrapped between the bottom layer 1 and the top layer 2, and the edge of the absorbent core 4 is fixed to the bottom layer 1 and the top layer 2. The flow-guiding layer 3 covers the surface of the absorbent core 4. A skin-friendly layer 5 is fixed to the surface of the top layer 2, and an exposure groove 51 is provided in the middle of the skin-friendly layer 5, and a portion of the top layer 2 is exposed in the exposure groove 51.

[0032] In the above technical solution, a skin-friendly layer 5 is designed, which makes the contact with the skin more comfortable and reduces the contact area. An exposure groove 51 is obtained by cutting the vaginal opening, which can avoid the vulva from being stuffy and damp due to the surface layer 2 sticking to the vulva.

[0033] The pure cotton skin-friendly layer 5 has good breathability, which can increase comfort.

[0034] Secondly, the design of the exposure groove 51 can catch menstrual blood when it flows out of the vaginal opening.

[0035] The surface layer 2 is a non-woven fabric layer.

[0036] The skin-friendly layer 5 is made of pure cotton.

[0037] See Figure 1and Figure 2 As shown, the thickness of the skin-friendly layer 5 is 0.8 mm.

[0038] The skin-friendly layer 5 is composited above the surface layer 2, so its edge is slightly higher than the surface layer, and can hold menstrual blood through the exposure groove 51.

[0039] See Figure 1 and Figure 2 As shown, the inner walls on both sides of the exposure groove 51 are wavy inner walls 551.

[0040] When using this panty liner, it should fit snugly against the vulva, with its two ends curved upwards. The wavy inner wall 551 allows menstrual blood to flow more slowly along the wavy inner wall 551, making it easier for the core 4 to absorb menstrual blood.

[0041] See Figure 1 As shown, on the surface of the surface layer 2, a vertically penetrating rapid permeation hole 221 is machined at the low point position corresponding to the wavy inner wall 551.

[0042] When menstrual flow is heavy, panty liners have lower absorbency than sanitary napkins, so they tend to flow on the surface. The menstrual blood can then quickly seep down through the quick-penetration pores 221.

[0043] See Figure 3 As shown, the surface of the flow guiding layer 3 is processed with through holes 331 corresponding to the rapid permeation holes 221.

[0044] The 331 through-hole allows menstrual blood to seep in quickly.

[0045] See Figure 4 As shown, the absorbent core 4 includes an outer shell 41 and polymer absorbent particles 42 filled inside the outer shell 41. The outer shell 41 is made of non-woven fabric.

[0046] The high-molecular-weight absorbent particles 42 can effectively absorb menstrual blood.
