DETAILED DESCRIPTION

[0018] Please refer to Figure 1-Figure 3 An embodiment of the present invention provides a light incontinence pad, which includes a body 10 having a surface layer 11, an absorption layer 12 and a bottom layer.

[0019] Specifically, the surface layer 11 is arranged on the side close to the user's skin, and the surface layer 11 should be at least partially liquid-permeable. The liquid-permeable means that body fluids can pass through the surface layer 11 into the structural layer below the surface layer 11, such as the absorption layer 12. Usually, the body fluids can also diffuse along the surface layer 11 to further improve the absorption efficiency of the absorbent for the body fluids. The at least partially liquid-permeable means that at least the area of ​​the surface layer 11 corresponding to the body fluid discharge area is liquid-permeable. The body fluid discharge area can be the vaginal opening, urethral opening and other locations.

[0020] Since the surface layer 11 contacts the skin, it is preferred to use a low-irritation, soft material, such as a material with a unit area weight of 10 to 60 g / m 2 The sheet materials include gauze, cotton, spunlace non-woven fabric, hot air non-woven fabric and the like, more preferably, hot air non-woven fabric composed of thermoplastic synthetic fibers, as the synthetic fibers constituting the above-mentioned hot air non-woven fabric, polyolefin fibers such as polyethylene (PE) fiber and polypropylene (PP) fiber, polyester fibers, polyamide fibers such as nylon, etc. can be used, in some optional embodiments, natural fibers or viscose fibers can also be added at the same time to further reduce the irritation to the skin, these natural fibers can include wood fibers, cotton fibers, etc.

[0021] The absorption layer 12 is stacked under the surface layer 11. Specifically, the absorption layer 12 is a three-dimensional network structure formed by entanglement of a plurality of fibers that are properly connected. A plurality of pores are distributed between the three-dimensional network structure, and body fluids can be absorbed and diffused through the pores.

[0022] Furthermore, the absorbent layer 12 may also include a covering layer, which covers or wraps the three-dimensional network structure. At the same time, the covering layer is a liquid-permeable material. In some specific embodiments, the covering layer may be a non-woven fabric or toilet paper. At the same time, the covering layer is preferably soft, for example, with a unit area weight of 10 to 60 g / m 2 The covering layer may be made of sheet materials such as gauze, cotton cloth, spunlace nonwoven fabric, hot air nonwoven fabric, toilet paper, etc. More preferably, the covering layer has a lower basis weight relative to the surface layer 11.

[0023] The bottom layer is stacked under the absorbent layer 12. In order to prevent body fluids from passing through the surface layer 11 and contaminating the user's clothes, the bottom layer is usually made of a water-repellent material, specifically, a PE film, SMS non-woven fabric, a non-woven fabric with a water-repellent surface treatment, etc. Preferably, the bottom layer allows gases, such as water vapor, to pass through, but body fluids cannot pass through, so that the user will not feel stuffy when using the material.

[0024] The surface layer 11 and the bottom layer are combined along the edge of the main body 10, so that the surface layer 11 and the bottom layer are combined into a peripheral joint part 106, and the surface layer 11 and the bottom layer are surrounded along the peripheral joint part 106 to form a accommodating space, and the absorption layer 12 is accommodated in the accommodating space. The combination refers to the connection of the combined materials to form a whole, which can usually be formed by hot melting or bonding. The hot melting can be achieved by heating the material itself to reach the melting point temperature, locally melting it, and forming a connection after solidification, or by external energy such as ultrasound acting on the material to cause the material to melt locally at high temperature, and then solidify to form a connection. The bonding can be achieved by using an adhesive to connect adjacent materials under the action of the adhesive.

[0025] The body 10 comprises a first end 1001 and a second end 1002. In this embodiment, the first end 1001 is located at Figure 1 The second end 1002 of the body is located at the upper side of Figure 1 The main body 10 includes a length direction and a width direction, wherein the length direction is Figure 1 The up-down direction is the direction from the first end 1001 of the body to the second end 1002 of the body, and the width direction is the direction perpendicular to the length direction. Specifically, Figure 1 In the left and right directions, in addition, the width of the main body 10 at the first end 1001 of the main body is greater than the width of the second end 1002 of the main body, so that the main body 10 as a whole presents an inverted triangle that is wide at the top and narrow at the bottom.

[0026] Furthermore, the body 10 also includes a middle section 1003, which is located between the first end 1001 of the body and the second end 1002 of the body, and the width of the middle section 1003 is greater than the width of the first end 1001 of the body, that is, the body 10 presents a shape in which the width gradually increases from the first end 1001 of the body to the middle section 1003, and gradually decreases from the middle section 1003 to the second end 1002 of the body.

[0027] The absorption layer 12 includes a pair of main slits 121 arranged along the length direction of the main body 10. It can be understood that the pair of main slits 121 are arranged at intervals, and the absorption layer 12 is divided into a main absorption area 101 and a left absorption area 102 and a right absorption area 103 located on both sides of the main absorption area 101 by the pair of main slits 121. It can be understood that the main absorption area 101 is the area located between the pair of main slits 121, the left absorption area 102 is the area located on the left side of the left main slit 121, and the right absorption area 103 is the area located on the right side of the right main slit 121.

[0028] A pair of side slits 122 are respectively located on both sides of a pair of main slits 121, and each side slit 122 is arranged corresponding to a main slit 121. Specifically, a side slit 122 is correspondingly arranged on the left side of the left main slit 121, and a side slit 122 is correspondingly arranged on the right side of the right main slit 121. The side slits 122 and the corresponding main slits 121 are arranged in a form in which the distance between them gradually decreases from the first end 1001 of the main body to the second end 1002 of the main body, that is, the distance between the side slit 122 on the left and the main slit 121 on the left gradually decreases from the first end 1001 of the main body to the second end 1002 of the main body, and the distance between the side slit 122 on the right and the main slit 121 on the right also gradually decreases from the first end 1001 of the main body to the second end 1002 of the main body.

[0029] In this embodiment, the body 10 is symmetrically arranged along the first virtual straight line 104 , a pair of the main slits 121 are arranged in parallel and spaced apart and symmetrically arranged along the first virtual straight line 104 , and a pair of the side slits 122 are also symmetrically arranged along the first virtual straight line 104 .

[0030] Furthermore, the main slit 121 is in a straight line shape, and the side slit 122 is also in a straight line shape, and the angle between the side slit 122 and the corresponding main slit 121 is 10° to 15°.

[0031] Furthermore, the main slit 121 and / or the side slit 122 have a trapezoidal cross section, and the upper width is smaller than the lower width, so that the main slit 121 and the side slit 122 can be easily removed from the mold during the demolding process.

[0032] It can be understood that the side slits 122 and the corresponding main slits 121 should be separated, and the side slits 122 should be arranged adjacent to the first end 1001 of the body, so that the side slits 122 are located at a wider position of the body 10. When the present invention is used, the side slits 122 are approximately located at or adjacent to the hips. The length of the main slits 121 should be greater than the side slits 122. When the present invention is used, the main slits 121 approximately correspond to the thigh roots. At the same time, the main slits 121 and the side slits 122 should penetrate the thickness direction of the absorbent layer 12, and their The width should be less than or equal to 4 mm. It is found that when the width of the main slit 121 and the side slit 122 is less than 4 mm, the width of the main slit 121 and the side slit 122 will be less than or equal to the fiber length. Specifically, the length of the softwood fluff pulp fiber constituting the absorbent layer 12 is usually less than or equal to 4 mm. Therefore, after the main slit 121 and the side slit 122 are formed on the absorbent layer 12, some fibers can still be overlapped, but these overlapping fibers are not enough to form a layer. By the above arrangement, the following effects are formed: First, due to the arrangement of the main slit 121 and the side slit 122, the hip and thigh root have good ventilation effect.

[0033] Second, since the main slit 121 and the side slit 122 form weakened areas at the same time, the main body 10 can be easily bent along the main slit 121 and the side slit 122, especially the thigh root can be bent along the main slit 121, and the hip position can be bent along the side slit 122 during exercise, so that this arrangement can greatly improve the comfort during exercise.

[0034] 3. Due to the overlap between the fibers, the liquid can still pass through the slits, and will not cause a significant impact on the absorption performance. In particular, when the absorption layer 12 is bent along the main slits 121 and the side slits 122, the impact on the overall absorption performance is smaller. In fact, since the main slits 121 and the side slits 122 actually result in less fiber reduction, the absorption amount is basically unaffected, and only the lateral absorption rate is affected to a certain extent.

[0035] Fourthly, due to the formation of the main slit 121 and the side slit 122, the areas on both sides of the main slit 121 and the side slit 122 become loose, and the pores in this area become larger, which can help the body fluid to diffuse along this area when multiple body fluid outflows occur.

[0036] Further research has shown that the width of the main slit 121 and the side slit 122 can be set to 1 / 3 to 1 / 2 of the average length of the fibers constituting the absorption layer. On the one hand, it can form a suitable fiber overlap to ensure the absorption performance, and on the other hand, it can maintain the good air permeability of the main slit 121 and the side slit 122 and the bending effect on the absorption layer 12. In a more specific embodiment, the width of the main slit and the side slit is 0.8 mm to 2.0 mm.

[0037] Furthermore, the absorption layer 12 includes an upper absorption area 124 adjacent to the first end 1001 of the main body and a lower absorption area 123 adjacent to the second end 1002 of the main body along the length direction, wherein the thickness of the lower absorption area 123 is greater than the thickness of the upper absorption area 124. More specifically, the absorption layer 12 includes a second virtual straight line 105 separating the upper absorption area 124 and the lower absorption area 123, and the upper side of the second virtual straight line 105 is the upper absorption area 124 with a smaller thickness, and the lower side of the second virtual straight line 105 is the lower absorption area 123 with a larger thickness. It can be understood that the main body 10 will be able to be easily bent along the second virtual straight line 105, so that the main body 10 can be more easily attached to the skin.

[0038] Furthermore, SAP14 is provided in the lower absorption zone 123. SAP14 is a polymer water-absorbing material. Usually, the SAP14 is polyacrylate. In a specific embodiment, the SAP14 is sodium polyacrylate particles with a particle size of 50 μm to 900 μm.

[0039] Furthermore, the side slit 122 includes a side slit first end 1221 and a side slit second end 1222, wherein the side slit first end 1221 is adjacent to the first end 1001 of the main body, and the side slit second end 1222 is toward the second end 1002 of the main body. At the same time, the side slit second end 1222 extends to the second virtual straight line 105. The extension to the second virtual straight line 105 means that the endpoint of the side slit second end 1222 is located on the second virtual straight line 105.

[0040] Furthermore, the side slit 122 is straight, the main slit 121 includes a main slit first end 1211 adjacent to the first end 1001 of the main body and a main slit second end 1212 adjacent to the second end 1002 of the main body, the side slit 122 includes a virtual extension line 1223 from the side slit second end 1222 to the second end 1002 of the main body, the extension line 1223 intersects with the corresponding main slit 121 at the main slit second end 1212, and the intersection at the main slit second end 1212 means that the intersection of the extension line 1223 and the main slit 121 is the main slit second end 1212.

[0041] Furthermore, an elastic zone 107 is provided on the peripheral joint 106, and the elastic zone 107 includes an elastic band provided on the peripheral joint 106 and along the length direction of the main body 10, and the elastic band is configured to have an elastic force along the length direction of the elastic zone 107, so as to adapt to different users and improve the comfort of use, wherein the elastic zone 107 includes an elastic zone first end 1071 toward the first end 1001 of the main body and an elastic zone second end 1072 toward the second end 1002 of the main body, wherein the elastic zone first end 1071 is located on the second virtual straight line 105, and the elastic zone second end 1072 is flush with the second end 1212 of the main slit.

[0042] Furthermore, the main slit first ends 1211 of the pair of main slits 121 and the side slit first ends 1221 of the pair of side slits 122 are located on the same arc line.

[0043] Furthermore, the distance between the side slit second end 1222 and the main slit 121 is greater than or equal to 2 cm.

[0044] The above-mentioned features can further enhance the comfort of use, especially the comfort of use for the thigh root and adjacent hip. In a specific embodiment, when the same surface layer, absorption layer and bottom layer are used and basically the same shape is formed, in the structure of the present invention, the width of the main slit and the side slit are both 1.8 mm, the angle between the side slit and the main slit is 12°, and the absorption layer uses coniferous wood fluff pulp with an average fiber length of 3.5 mm. By using sensory tests, compared with the prior art, the feeling of stuffiness and humidity is reduced by an average of 28%. When worn for more than 4 hours, the feeling of stuffiness and humidity is reduced by an average of 44%.

[0045] The above description is only an implementation mode of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
