Description

Technical Field

[0001] This utility model belongs to the field of personal hygiene care products technology, specifically relating to a leak-proof suspended sanitary napkin. Background Technology

[0002] Suspended sanitary napkins are popular because their three-dimensional protective structure (suspended edge) better conforms to the body and prevents menstrual blood leakage. Currently, most suspended sanitary napkins on the market typically only have one layer of waterproof non-woven fabric covering the sides of the absorbent core and the bonding area with the suspended non-woven fabric. This waterproof non-woven fabric is then connected to the surface layer and the suspended edge. Even with this structure, leakage is still possible. For example, when the waterproof non-woven fabric is subjected to non-static water pressure generated by dynamic use such as walking or sitting / lying down, its waterproof performance is limited, and liquid may still seep through, causing leakage from the sides and underside of the sanitary napkin during use, affecting the user's comfort and safety. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this invention is to provide a leak-proof, suspended sanitary napkin, which is achieved through the following technical solution: A leak-proof suspended sanitary napkin includes a PE bottom film, an absorbent core, a diversion layer nonwoven fabric, a surface hydrophilic nonwoven fabric, a suspended edge nonwoven fabric, and a side waterproof nonwoven fabric. A leak-proof layer composed of a low-grammage PE film is bonded to the absorbent core. The leak-proof layer is either a leak-proof layer wrapped under the absorbent core or a side leak-proof PE layer.

[0004] Furthermore, the leak-proof layer wrapped under the absorbent core is located below the absorbent core, and the two sides are folded up and wrapped around the two sides of the absorbent core to form a large C-shaped structure. The side waterproof non-woven fabric is bonded to the edge of the surface hydrophilic non-woven fabric, and then bonded to the top of the large C-shaped structure.

[0005] Furthermore, the opening edge of the leak-proof layer wrapped under the absorbent core is bonded to the surface of the nonwoven fabric of the flow guiding layer.

[0006] Furthermore, the side leak-proof PE layer is located between the surface hydrophilic nonwoven fabric and the side waterproof nonwoven fabric, wrapping the side of the absorbent core. The upper edge of the side waterproof nonwoven fabric is fixedly connected to the side of the surface hydrophilic nonwoven fabric, and the two are integrated and then the side leak-proof PE layer is bonded to its inner side.

[0007] Furthermore, the basis weight of the low-basis-weight PE film is 8–25 g / m².

[0008] This invention creates a three-dimensional, continuous leak-proof barrier by using a low-grammage PE film as the leak-proof layer. This barrier is located directly on the side of the absorbent core, fundamentally compensating for the defect of easy leakage of the side waterproof non-woven fabric under dynamic pressure. It can effectively prevent liquid from leaking from the side and below. The low-grammage PE film used is thin and soft, and the added material will not cause stiffness, friction or other discomfort, perfectly inheriting the fit and comfort characteristics of the suspended sanitary napkin.

Detailed Implementation

[0010] The present invention will be further described below with reference to specific embodiments in order to better understand the technical solution.

[0011] Example 1

[0012] like Figure 1 As shown, a leak-proof suspended sanitary napkin has a main structure including a PE bottom film 1 as the bottom layer. On the upper surface of the PE bottom film 1, an absorbent core made of PE film with a weight of 8-25 g / m² is provided, and a leak-proof layer 7 is wrapped under it. The middle part of the PE film is laid flat on the PE bottom film 1, and its two side edges are folded up and wrapped around the lower part and two sides of the absorbent core 2 to form a large C-shaped structure.

[0013] The absorbent core 2 is placed under the absorbent body with a large C-shaped structure and wrapped in the leak-proof layer 7. Above the absorbent core 2, the flow-guiding nonwoven fabric 3 and the surface hydrophilic nonwoven fabric 4 are laid in sequence. The two sides of the surface hydrophilic nonwoven fabric 4 are bonded to the upper edge of the side waterproof nonwoven fabric 6. The lower edge of the surface hydrophilic nonwoven fabric 4 after being bonded to the side waterproof nonwoven fabric 6 is bonded to the upper outer side of the leak-proof layer 7 wrapped under the absorbent core 2. Finally, the suspended edge nonwoven fabric 5 is bonded to the outer side of the side waterproof nonwoven fabric 6, thus forming a three-dimensional protective enclosure.

[0014] Example 2

[0015] like Figure 2As shown, a leak-proof suspended sanitary napkin is described. The main structure of the sanitary napkin in this embodiment is basically the same as that in embodiment 1, except that the leak-proof layer structure is different. In this embodiment, the leak-proof layer is a side leak-proof PE layer 8. The side leak-proof PE layer 8 is located between the surface hydrophilic nonwoven fabric 4 and the side waterproof nonwoven fabric 6, and wraps the side of the absorbent core 2. The upper edge of the side waterproof nonwoven fabric 6 is fixedly connected to the side of the surface hydrophilic nonwoven fabric 4. After the two are integrated, the side leak-proof PE layer 8 is bonded to its inner side.

[0016] In use, the liquid permeates through the hydrophilic nonwoven fabric 4 and the flow-guiding nonwoven fabric 3 and is absorbed by the absorbent core 2. When the liquid diffuses to the edge of the absorbent core 2 and attempts to seep through the side waterproof nonwoven fabric 6, it is effectively blocked by the dense large C-shaped PE membrane on its inner side or the side leak-proof PE membrane 8. Because the PE membrane has absolute water resistance, even under high dynamic pressure, it can ensure that the liquid is locked inside the absorbent core, thereby achieving a good leak-proof effect.
