Summary of the Utility Model

[0003] The purpose of this application is to provide a washable sanitary pad that is convenient to wear, comfortable to wear, and can be reused.

[0004] This application provides a washable sanitary pad, which includes an outer layer and an inner layer sewn together at the outer edge. The inner layer includes a first inner layer that is skin-friendly. A hollow body with a small thickness is formed by hollowing out the middle part of the first inner layer from top to bottom. A second inner layer that is seamlessly thermally pressed and joined with the first inner layer and an absorption layer located below the second inner layer are filled in the hollow body. Two convex pendulums are formed at the left and right ends of the washable sanitary pad, and a first fastening member and a second fastening member that can be buckled together are respectively arranged on the convex pendulums.

[0005] Further, the first fastening member is a male buckle, and the second fastening member is a female buckle. Among them, there is one male buckle, and the two female buckles are arranged horizontally at intervals.

[0006] Further, the outer layer is a waterproof layer made of TPU fabric, and several tiny particles are sewn on the outer surface of the waterproof layer.

[0007] Further, the first inner layer is a cotton layer, the second inner layer is a cotton layer, the absorption layer is a superfine fiber layer, and the sum of the thicknesses of the second inner layer and the absorption layer is the same as the thickness of the first inner layer.

[0008] Further, the thickness of the sanitary pad is 2.2 millimeters to 3.5 millimeters. The width and height of the sanitary pad are 17 - 19 centimeters and 22 - 24 centimeters respectively. The width and height of the second inner layer are 9.5 - 10.5 centimeters and 21 - 22 centimeters respectively.

In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.

[0020] Referring to Figures 1 to 3 as shown, an embodiment of the present utility model provides a washable sanitary pad. The thickness of the sanitary pad is 2.2 millimeters to 3.5 millimeters. The width and height of the sanitary pad are 17 to 19 centimeters and 22 to 24 centimeters respectively. The width here is measured from the convex swinging edges on the left and right sides of Figure 1 It includes an outer layer 1 and an inner layer with the outer edges sewn together. The outer layer 1 is a whole waterproof layer made of TPU fabric, which has the characteristics of waterproof, breathable, and washable, can be reused, and has a more favorable price. The inner layer includes a first inner layer 2 that is skin-friendly. The thickness of the first inner layer 2 is 2 to 3.2 millimeters. A hollow body with a small thickness is dug out from the middle of the first inner layer 2 from top to bottom. The hollow body is filled with a second inner layer 3 that is seamlessly thermally pressed and joined with the first inner layer 2 and an absorption layer 4 located below the second inner layer 3. The absorption layer 4 is generally in a flat runway shape. In this application, a middle body is dug out from the middle of the inner layer from top to bottom. The hollow body is filled with the second inner layer 3 and the absorption layer 4. The absorption layer 4 is located below the second inner layer 3. In this way, on the premise of ensuring that the overall thickness of the sanitary pad remains unchanged, the thickness of the absorption layer 4 is increased, the absorption capacity during menstruation is improved, and the waste of a whole absorption layer 4 equivalent to the area of the outer layer 1 in the traditional method is reduced. Moreover, the first inner layer 2 and the second inner layer 3 adopt the seamless thermal pressing process, which reduces the discomfort of the user when wearing compared with the traditional sewing and fixing method.

[0021] In this embodiment, two convex pendulums are formed at the left and right ends of the washable sanitary pad. The convex pendulums are made of the same material as the outer layer 1 or the first inner layer 2 according to their inner or outer positions. A first fastening member 5 and a second fastening member 6 that can be buckled are respectively arranged on the convex pendulums. Specifically, the first fastening member 5 is a male buckle, and the second fastening member 6 is a female buckle. Among them, there is one male buckle, and the two female buckles are arranged at a horizontal interval, or two female buckles are arranged and one male buckle is arranged. The washable sanitary pad is wound around the crotch of the underwear and buckled and connected together through the first fastening member 5 and the second fastening member 6. When in use, the inner layer of the sanitary pad is the side close to the human body, the outer layer 1 fits the crotch of the underwear, and then it is wound around in the reverse direction from the left and right sides and the convex pendulums on both sides are buckled and connected through the two fastening members. This design method enables users to easily put this washable sanitary pad on the crotch position of the underwear and also facilitates removal. When the width of the crotch of the underwear is relatively large, the second fastening member 6 can buckle the relatively outer first fastening member 5. When the width of the crotch of the underwear is relatively small, the second fastening member 6 can buckle the relatively inner first fastening member 5 to meet the tightening and wearing requirements of different users.

[0022] As another preferred embodiment of the present utility model, a number of tiny particles 7 are sewn on the outer surface of the waterproof layer. A number of small, convex-shaped anti-slip particles 7 are also sewn on the surface of the TPU cloth of the outer layer 1. The anti-slip particles 7 can be plastic particles or small lining cloth particles. This design makes it easier to fix the sanitary pad in the underwear. On the premise of not contacting the human skin, it makes the sanitary pad and the underwear have greater friction and reduces the displacement of the sanitary pad caused by the user's walking or other actions.

[0023] In this embodiment, the first inner layer 2 is a cotton layer, and the second inner layer 3 is also a cotton layer, which is convenient for thermocompression molding with the edge of the first inner layer 2. The absorbent layer 4 is an ultra-fine fiber layer, and the ultra-fine fiber has better water absorption. The left, right, upper and lower outer edges of the second inner layer 3 and the absorbent layer 4 are sewn and fixed, or only the upper and lower edges are sewn and fixed, or thermocompression fixed, and then thermocompression fixed with the first inner layer 2. The sum of the thicknesses of the second inner layer 3 and the absorbent layer 4 is the same as the thickness of the first inner layer 2. Of course, the sum of their thicknesses can also be set to be greater than the thickness of the first inner layer 2, and the thickness of the second inner layer 3 is less than the thickness of the absorbent layer 4. Among them, the width and height of the second inner layer 3 are 9.5 - 10.5 cm and 21 - 22 cm respectively, and the width and height of the absorbent layer 4 are 8.5 - 9.5 cm and 21 - 22 cm respectively. Since the second inner layer 3 needs to be thermocompression bonded with the edge of the first inner layer 2, the width of the first inner layer 2 is designed to be slightly larger than the width of the absorbent layer 4.

[0024] The washable sanitary pad disclosed in the embodiment of the present utility model has the characteristics of being convenient for users to wear, comfortable to wear, having a large absorption capacity, not easy to slip, and being reusable.
