Description

Technical Field

[0001] This utility model relates to a sanitary pad. Background Technology

[0002] With social progress and improved living standards, people's requirements for hygiene are gradually increasing. In situations such as worship, travel, and outdoor activities, people still hope to lay out mats and maintain hygiene by engaging in activities on them. In these situations, people also hope to be able to perform simple, light activities or exercise on these mats, and at the same time, they hope to be able to dispose of them directly after the activities, as they are disposable products.

[0003] In these situations, people typically use two types of products. One type includes prayer mats, camping mats, picnic mats, training mats, yoga mats, etc. These products are relatively thick and heavy, making them inconvenient to carry. Furthermore, they are usually designed for reusability, which makes them wasteful to discard in the aforementioned situations. The other type of product consists of sheets such as plastic film or non-woven fabric, or even sanitary pads as shown in CN222265512U. However, these products are relatively thin, have almost no cushioning, and have a smooth surface, making them prone to damage or injury during the aforementioned activities. When multiple layers are directly stacked, they are prone to slippage between the layers, making them difficult to use.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] Therefore, this utility model provides a sanitary pad to solve the above-mentioned technical problems.

[0006] A sanitary pad includes a body, which comprises a top layer, a buffer layer, and a bottom layer stacked together. The buffer layer comprises a three-dimensional network structure formed by cross-linking of fibers. The body has a thickness of 3 mm or more. The body includes a support area, which includes a main support area with a plurality of pressure points. The pressure points have a depth of 1.5 mm or more, and the distribution density of the pressure points in the main support area is 1 to 40 points / cm².

[0007] The area of ​​the main support area is greater than or equal to 60% of the area of ​​the support area.

[0008] The pressure points are arranged at the same distance to form a single row of pressure lines, and the single row of pressure lines are arranged at the same distance to form a surface pattern. The distance between the pressure points on the single row of pressure lines is defined as L1, and the distance between the single row of pressure lines in the surface pattern is L2. Thus, L1 = 0.8~8mm, and similarly, L2 = 0.8~8mm.

[0009] Wherein, when the fiber is coniferous wood fiber, L1=2~8mm, L2=2~8mm; when the fiber is bamboo pulp fiber, L1=1.2~3.8mm, L2=1.2~3.8mm; when the fiber is broadleaf wood fiber, L1=0.8-2.4mm.

[0010] The sanitary pad is rectangular, including a pair of first sides arranged opposite each other and a pair of second sides connecting the pair of first sides. The adjacent first sides are perpendicular to the second sides. At the same time, the center line of the adjacent pressure points in the single row of pressure lines forms a first virtual straight line, which is inclined to the first side.

[0011] The angle between the first virtual line and the first side is 30-60°.

[0012] Each pressure point has an area of ​​1 mm² or more.

[0013] The body also includes an adhesive layer disposed on the bottom layer.

[0014] The buffer layer also includes a covering layer on the outside of the buffer layer. The covering layer includes a lower covering layer located below the buffer layer and an upper covering layer located above the buffer layer. The lower covering layer includes a folded edge that is folded to the upper side of the buffer layer, and the upper covering layer is combined with the folded edge.

[0015] The main support area includes at least one high-density support area and a surrounding area enclosing the high-density support area, wherein the distribution density of the pressure points in the high-density support area is greater than the distribution density of the pressure points in the surrounding area.

[0016] Beneficial Effects: This utility model provides a sanitary pad, including a main body. The main body includes a top layer, a buffer layer, and a bottom layer stacked together. The buffer layer includes a three-dimensional network structure formed by cross-linking of fibers. The main body has a thickness of 3 mm or more. The main body includes a support area, which includes a main support area with several pressure points. The pressure points have a depth of 1.5 mm or more, and the distribution density of the pressure points in the main support area is 1 to 40 points / cm². Through the above configuration, on the one hand, the main body has sufficient buffer height to be suitable for light exercise. On the other hand, misalignment or slippage between the top layer and the buffer layer is not easily generated. At the same time, it allows the user to form a high friction force with the sanitary pad, and the pressure points will not detach when pressure is applied to the sanitary pad or when impact is formed on the surface of the sanitary pad. The product is also suitable for single use. Attached Figure Description

Detailed Implementation

[0025] Please refer to Figures 1-2 The first embodiment of this utility model provides a sanitary pad, and the application will be further described below with reference to the accompanying drawings.

[0026] The sanitary pad includes a body 10, which includes a top layer 11, a buffer layer 12, and a bottom layer 13 stacked together.

[0027] The surface layer 11 faces the user and is used for contact with the user. Preferably, the surface layer 11 is low-irritant and soft, for example, with a weight per unit area of ​​10-60 g / m². 2 Sheet materials such as gauze, cotton cloth, spunlace nonwoven fabric, and hot-air nonwoven fabric are preferred. More preferably, hot-air nonwoven fabric is made of thermoplastic synthetic fibers. As the synthetic fibers constituting the hot-air nonwoven fabric, polyethylene (PE) fiber, polypropylene (PP) fiber and other polyolefin fibers, polyester fibers, nylon and other polyamide fibers, etc. can be used. In some optional embodiments, natural fibers or viscose fibers may also be added at the same time. These natural fibers may include wood fibers, cotton fibers, etc.

[0028] The buffer layer 12 includes a three-dimensional network structure formed by fiber cross-linking. The cross-linking can specifically be the entanglement between fibers, the bonding between fibers through adhesive, or the bonding formed by fiber melting. It is understood that the three-dimensional network structure formed by fiber cross-linking includes a number of pores. The three-dimensional network structure formed by fiber cross-linking has a certain elasticity, which gives the three-dimensional network structure a buffering effect.

[0029] Furthermore, the buffer layer 12 may also include absorbent material distributed within the pores for absorbing substances such as sweat.

[0030] In addition, the fiber can be plant fiber or synthetic fiber. When the fiber is plant fiber, it can specifically be coniferous wood fiber, bamboo pulp fiber or hardwood fiber. When the fiber is coniferous wood fiber, the average length of the fiber is 2-4 mm. When the fiber is bamboo pulp fiber, the average length of the fiber is 1.2-1.9 mm. When the fiber is hardwood fiber, the average length of the fiber is 0.8-1.2 mm.

[0031] The bottom layer 13 is used to prevent liquid penetration and is disposed on the side away from the user. The bottom layer 13 is usually a water-repellent material, specifically, it can be a PE film, SMS non-woven fabric, etc. Preferably, the bottom layer 13 allows gas, such as water vapor, to pass through, but liquid cannot pass through, so that it will not be stuffy when used.

[0032] The body 10 has a thickness of 3 mm or more, and the body 10 includes a support area, which includes a main support area 101 with a plurality of pressure points 21. The pressure points 21 have a depth of 1.5 mm or more, and the distribution density of the pressure points 21 in the main support area 101 is 1 to 40 per cm².

[0033] Through the above settings, on the one hand, the main body 10 has sufficient cushioning height, especially for light exercise, such as jogging or exercising on the sanitary pad, so that the main body 10 can form a cushion and reduce the chance of injury. On the other hand, when the pressure point 21 is set to a depth of greater than or equal to 1.5mm, it is not easy for the surface layer 11 and the buffer layer 12 to misalign or slip. At the same time, when the distribution density of the pressure point 21 is 1 to 40 points / cm², it allows the user to form a high friction force with the sanitary pad. In addition, at this pressure point 21 distribution density, when pressure is applied to the sanitary pad or when an impact is formed on the surface of the sanitary pad, the mutual squeezing action between the pressure points 21 will not cause the pressure points 21 to detach.

[0034] Understandably, in this embodiment, the support area is the upper surface of the surface layer 11, and the area of ​​the main support area 101 is greater than or equal to 60% of the area of ​​the support area, so that the user has sufficient usable area. More specifically, the user will mainly sit, lie down or step on the main support area 101 during use. Preferably, the area of ​​the main support area 101 is greater than or equal to 80% of the area of ​​the support area.

[0035] Furthermore, the body 10 has a thickness of 4-25 mm, and the pressure point 21 has a depth of 1.8-2.5 mm, so that the body 10 has sufficient buffer height and the pressure point 21 maintains its shape when subjected to impact or pressure.

[0036] Please refer to the following for further details. Figures 3-5 The pressure points 21 are arranged in the main support area 101 in the following manner: the pressure points 21 are arranged repeatedly at the same distance to form a single row of pressure lines, and the single row of pressure lines are arranged repeatedly at the same distance to form a surface pattern. The distance between the pressure points 21 in the single row of pressure lines is defined as L1, and the distance between the single row of pressure lines in the surface pattern is defined as L2. Then, L1 = 0.8~8mm, and similarly, L2 = 0.8~8mm.

[0037] Studies have found that when the spacing between adjacent pressure points 21 is 1-2 times the average fiber length, the impact between adjacent pressure points 21 is smaller when subjected to pressure, while the buffer layer 12 has good resilience. Preferably, when the fiber is coniferous wood fiber, L1=2-8mm, L2=2-8mm; when the fiber is bamboo pulp fiber, L1=1.2-3.8mm, L2=1.2-3.8mm; and when the fiber is broadleaf wood fiber, L1=0.8-2.4mm.

[0038] Furthermore, the sanitary pad is rectangular, including a pair of first sides 1001 arranged opposite each other and a pair of second sides 1002 connecting the pair of first sides 1001. The adjacent first sides 1001 and second sides 1002 are perpendicular. At the same time, the center line of the adjacent pressure points 21 in the single row of pressure lines forms a first virtual straight line 1003, and the first virtual straight line 1003 is inclined to the first side 1001.

[0039] Furthermore, the angle between the first virtual line 1003 and the first side 1001 is 30-60°.

[0040] Furthermore, a second virtual straight line 1004 is formed between the corresponding pressure points 21 of adjacent single-row pressure lines in the planar pattern, and the second virtual straight line 1004 is perpendicular to the first virtual straight line 1003.

[0041] In addition, each pressure point 21 should have an area of ​​1 mm² or more. Preferably, the area refers to the projected area of ​​the pressure point 21 on the surface layer 11. Preferably, the pressure point 21 is rectangular. More preferably, the area of ​​the pressure point 21 is 1.2-2.5 mm².

[0042] Furthermore, the body 10 also includes an adhesive layer 16 disposed on the bottom layer 13, which is used to fix the body 10 to the ground for easy use. It is understood that the adhesive layer 16 is disposed on the opposite side of the bottom layer 13 and the top layer 11.

[0043] Furthermore, the body 10 also includes a protective layer 17 disposed on the adhesive layer 16 to prevent the adhesive layer 16 from unintentionally adhering to the ground or other objects. The protective layer 17 is release paper.

[0044] Furthermore, the adhesive layer 16 has an area of ​​100 mm².

[0045] Furthermore, the adhesive layer 16 is located at the four corners of the bottom layer 13.

[0046] Furthermore, the body 10 also includes a peripheral joint 102, where the surface layer 11 and the bottom layer 13 are joined along the peripheral joint 102 to form a whole. It can be understood that the joining of the surface layer 11 and the bottom layer 13 creates a receiving space along the peripheral joint 102, and the buffer layer 12 is housed within this receiving space. The joining refers to the connection of the joined materials to form a whole, typically through hot melting or bonding. Hot melting involves heating the material itself to its melting point, causing localized melting and solidification to form a connection. Alternatively, external energy such as ultrasound can be applied to the material, causing localized high-temperature melting and solidification to form a connection. Bonding uses an adhesive to connect adjacent materials under the action of the adhesive.

[0047] Furthermore, the outer side of the buffer layer 12 also includes a covering layer that covers the buffer layer 12. The covering layer includes a lower covering layer 14 located below the buffer layer 12 and an upper covering layer 15 located above the buffer layer 12. The lower side is the side adjacent to the bottom layer 13, and the upper side is the side adjacent to the surface layer 11. The covering layer enables the three-dimensional network structure to maintain its integrity under pressure or impact. On the other hand, the covering layer facilitates the movement of the buffer layer 12 after it is formed, thus facilitating manufacturing.

[0048] Furthermore, the lower covering layer 14 includes a folded edge 141 folded over the upper side of the buffer layer 12, and the upper covering layer 15 is combined with the folded edge 141.

[0049] Furthermore, the folded edge 141 has a width of 20 mm or more.

[0050] Furthermore, the lower covering layer 14 or the upper covering layer 15 can be non-woven fabric or toilet paper, preferably a soft material, such as one with a unit area weight of 10-60 g / m². 2 Sheet materials such as gauze, cotton cloth, spunlace nonwoven fabric, hot air nonwoven fabric, and toilet paper.

[0051] Please refer to the following for further details. Figure 6 In the second embodiment of this utility model, the main support area 101 includes at least one high-density support area 301 and a peripheral area 302 surrounding the high-density support area 301, wherein the distribution density of the pressure points 21 in the high-density support area 301 is greater than the distribution density of the pressure points 21 in the peripheral area 302.

[0052] Furthermore, the distribution density of pressure points 21 in the high-density support zone 301 is more than 50% higher than the distribution density of pressure points 21 in the peripheral zone 302.

[0053] Furthermore, there are at least two high-density support areas 301, and the two high-density support areas 301 are set separately.

[0054] By setting up a high-density support zone 301, a higher buffering effect is achieved, which can buffer against higher intensity movements or greater impacts.

[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
