Description

Technical Field

[0001] The utility model relates to the technical field of sanitary products, in particular to an absorbent body and a sanitary napkin and a sanitary panty having the same. Background Art

[0002] With the improvement of people's living standards, women's sanitary napkins pursue thinner and lighter performance. Especially in hot summer, users are more willing to use thinner and lighter sanitary napkins or sanitary panties. However, in existing sanitary napkins or sanitary panties, in order to pursue thinner and lighter performance, the absorbent body of the sanitary napkin or sanitary panty is pressed tightly, often ignoring or reducing the liquid absorption performance and diffusion performance of the sanitary napkin or sanitary panty. Users need to change sanitary napkins or sanitary panties more frequently. For women with heavy menstrual flow, when using such sanitary napkins or sanitary panties, the risk of blood leakage is higher. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides an absorbent body and a sanitary napkin and a sanitary panty having the same, which can ensure the liquid absorption performance and diffusion performance while having a thinner and lighter performance.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] An absorbent body is provided with multiple groups of pressing points. Each group of pressing points has multiple pressing points. There is a spacing distance between adjacent pressing points. Multiple pressing points in the same group jointly surround to form a three-dimensional unit. The three-dimensional unit is arranged on the upper surface of the absorbent body and bulges upward. Multiple three-dimensional units are formed on the absorbent body, and adjacent two three-dimensional units are connected to each other.

[0006] The utility model has at least the following beneficial effects: The overall absorbent body is pressed thin through multiple pressing points on the absorbent body to achieve a thinner and lighter effect. The three-dimensional unit formed by the surrounding of the pressing points bulges upward. The material density at the position of the three-dimensional unit is lower than the material density at the position of the pressing points, which can improve the liquid absorption performance and diffusion performance and reduce the risk of liquid leakage.

[0007] As a further improvement of the above technical solution, multiple three-dimensional units are evenly arranged on the absorbent body. The shape of each three-dimensional unit is the same, and the size of each three-dimensional unit is the same. With such a setting, the liquid entering the absorbent body can be evenly dispersed to each position of the absorbent body, and the thinner and lighter performance of the absorbent body can be ensured. Moreover, the mechanical debugging in the processing process is simpler and easier to operate.

[0008] As a further improvement of the above technical solution, the absorbent body is provided with a first absorption area and a second absorption area. The second absorption area is located in the middle of the absorbent body, and the first absorption area is located on the side of the second absorption area. The first absorption area and the second absorption area respectively include a plurality of the three-dimensional units. The top view area of a single three-dimensional unit located in the second absorption area is larger than the top view area of a single three-dimensional unit located in the first absorption area. The density of the pressure points set in the second absorption area is smaller than the density of the pressure points set in the first absorption area, so that the fluidity of the liquid is better, and it is more conducive to ventilation and reduces the growth of bacteria.

[0009] As a further improvement of the above technical solution, the second absorption area extends along the front-back direction and extends to the rear end of the absorbent body. There are a plurality of the three-dimensional units in the second absorption area, and the plurality of the three-dimensional units in the second absorption area are arranged along the front-back direction. With such a setting, the density of the pressure points at the rear end of the absorbent body can be reduced, which is more conducive to the diffusion of the liquid, and is also conducive to the ventilation of the user's buttocks. Moreover, it can fit the user's buttocks and reduce the occurrence of liquid leakage.

[0010] As a further improvement of the above technical solution, the spacing distance between two adjacent pressure points is in the range of greater than or equal to 5 mm and less than or equal to 30 mm. When the spacing distance between two adjacent pressure points is within this range, the three-dimensional effect of the three-dimensional unit formed by the surrounding pressure points is better.

[0011] As a further improvement of the above technical solution, the diameter of each pressure point is in the range of greater than or equal to 1 mm and less than or equal to 3 mm. When the diameter of the pressure point is set within this range, the three-dimensional effect of the three-dimensional unit formed by the surrounding pressure points is better, taking into account the thinness, diffusibility and absorbability of the absorbent body.

[0012] As a further improvement of the above technical solution, the diameters of each pressure point are the same. With such a setting, it is more convenient to process and manufacture the absorbent body, and the production and processing efficiency can be improved.

[0013] As a further improvement of the above technical solution, the middle parts of the left and right side edges of the absorbent body are recessed towards the center of the absorbent body. The absorbent body is located between the user's two thighs. Since the left and right side edges of the absorbent body are recessed towards the center, it can avoid the contact between the left and right side edges of the absorbent body and the inner thighs of the user from scratching the user's skin, and improve the comfort of use.

[0014] A sanitary napkin includes the absorbent body according to any one of the above technical solutions. Since the absorbent body is provided in the sanitary napkin, it can maintain thinness while ensuring the liquid absorption performance and diffusion performance of the sanitary napkin, and reduce the risk of liquid leakage.

[0015] A sanitary pant, comprising the absorbent body described in any one of the above technical solutions. Since the absorbent body is provided in the sanitary pant, it can maintain thinness while ensuring the liquid absorption performance and diffusion performance of the sanitary pant, and reducing the risk of liquid leakage.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model. Each technical feature in the present utility model can be combined interactively on the premise of not conflicting with each other.

[0028] Referring to Figures 1 to 5 , in a first aspect, an embodiment of the present utility model provides an absorber 100, which is provided with a plurality of pressure points 110, and there is an interval distance between the pressure points 110. The plurality of pressure points 110 are divided into multiple groups, and each group of pressure points 110 is respectively provided with a plurality of pressure points 110. A plurality of pressure points 110 in the same group jointly surround and form a three-dimensional unit 120. The three-dimensional unit 120 is located on the upper surface of the absorber 100 and is provided to bulge upward. Since each group of pressure points 110 respectively forms a three-dimensional unit 120, a plurality of three-dimensional units 120 are formed on the absorber 100.

[0029] In this embodiment, two adjacent three-dimensional units 120 are connected to each other, and two adjacent three-dimensional units 120 have a common side. That is, in two adjacent three-dimensional units 120, a group of pressure points 110 forms the first three-dimensional unit 120, and two of the pressure points 110 in this group of pressure points 110 respectively overlap with two of the pressure points 110 in another group of pressure points 110. Another group of pressure points 110 forms the second three-dimensional unit 120, and the overlapping pressure points 110 are respectively located at both ends of the common side of the two three-dimensional units 120.

[0030] It can be understood that during use, the upper surface of the absorbent body 100 is the side close to the skin of the user's private part. In this embodiment, through a plurality of pressure points 110, the overall thickness of the absorbent body 100 can be thinned, thereby achieving a thin and light effect. Moreover, the three-dimensional unit 120 bulges upward, and the material density at the position of the three-dimensional unit 120 is lower than that at the position of the pressure points 110, having a fluffy feeling. The user feels softer and more comfortable when contacting it, and has a higher penetration effect.

[0031] Moreover, by setting the pressure points 110, the upper surface of the absorbent body 100 can be made uneven, thereby increasing the area of the upper surface of the absorbent body 100, which is more conducive to improving the liquid absorption efficiency.

[0032] In addition, with such a setting, two adjacent three-dimensional units 120 are connected to each other. Since the absorbent body 100 itself has a certain liquid diffusion performance, the liquid can flow between two adjacent three-dimensional units 120, avoiding the situation where the liquid is blocked at a certain position of the absorbent body 100. After the liquid diffuses, it is easier to penetrate downward to the water-locking layer for storing the liquid to keep the upper surface of the absorbent body 100 dry.

[0033] It can be understood that the absorbent body 100 can be made of materials such as non-woven fabric and cotton. In this embodiment, the absorbent body 100 is made of cotton material, which has good absorption performance and can be easily compacted. After the pressure points 110 are formed on the absorbent body 100 formed by the cotton material, the fluffy cotton material between the pressure points 110 can easily form the three-dimensional unit 120.

[0034] In some embodiments, the three-dimensional units 120 formed by multiple groups of pressure points 110 are evenly distributed on the absorbent body 100, and the shapes and sizes of the three-dimensional units 120 formed by each group of pressure points 110 are the same. Refer to Figure 1 . With such a setting, the liquid entering the absorbent body 100 can be evenly dispersed to each position of the absorbent body 100, and the thin and light performance of the absorbent body 100 can be ensured, and the processing process is simpler and easier to operate.

[0035] In some embodiments, each group of pressure points 110 has four, that is, each three-dimensional unit 120 is respectively formed by four pressure points 110. In this embodiment, the four pressure points 110 are respectively arranged at the four corners of the three-dimensional unit 120. Looking down at the absorbent body 100, each three-dimensional unit 120 is square.

[0036] It can be understood that each group of pressure points 110 can also be set to six, and a three-dimensional unit 120 is jointly formed by six pressure points 110, and the three-dimensional unit 120 is hexagonal.

[0037] In some embodiments, the absorbent body 100 is provided with a first absorption area 101 and a second absorption area 102. Among them, the second absorption area 102 is arranged at the middle position of the absorbent body 100, and the first absorption area 101 is arranged at the side of the second absorption area 102. In the first absorption area 101 and the second absorption area 102, a number of three-dimensional units 120 are respectively arranged. Specifically, when viewed from above, the area of a single three-dimensional unit 120 located in the second absorption area 102 is larger than the area of a single three-dimensional unit 120 located in the first absorption area 101, that is, the setting density of the pressure points 110 in the second absorption area 102 is lower than the setting density of the pressure points 110 in the first absorption area 101.

[0038] With such a setting, when the absorbent body 100 is applied to a sanitary napkin or a sanitary panty, the second absorption area 102 can be aligned with the vaginal orifice of the user and fit the physiological structure of the human body. Since the setting density of the pressure points 110 in the second absorption area 102 is smaller, the fluid flow performance is better. Moreover, the overall density of the absorbent body 100 in this area is smaller, which is more conducive to ventilation, improves the diffusion performance of the liquid, and reduces the growth of bacteria at the same time.

[0039] In some embodiments, the second absorption area 102 extends along the front-back direction and is arranged in the middle of the absorbent body 100, and the rear end of the second absorption area 102 extends to the rear end of the absorbent body 100, reducing the density of the pressure points 110 at the rear end of the absorbent body 100, which is more conducive to the diffusion of the liquid and also conducive to the ventilation of the wearer's buttocks.

[0040] Refer to Figure 2 , the three-dimensional units 120 located in the second absorption area 102 are in a rhombus shape, and a plurality of rhombus-shaped three-dimensional units 120 are arranged along the front-back direction, fitting the physiological structure of the wearer. When in use, a row of rhombus-shaped three-dimensional units 120 in the second absorption area 102 can make the absorbent body 100 fit the skin of the wearer more closely, reduce the occurrence of liquid leakage, and improve the safety of the sanitary napkin or the sanitary panty.

[0041] In some embodiments, the second absorption area 102 extends along the front-back direction and forms a rectangular area. Only one three-dimensional unit 120 is arranged in the second absorption area 102, and this three-dimensional unit 120 is located at the middle position of the absorbent body 100. Refer to Figure 3 . The pressure points 110 forming the three-dimensional unit 120 are arranged at the edge of the second absorption area 102 and coincide with some of the pressure points 110 in the first absorption area 101.

[0042] With such a setting, the upper surface of the second absorption area 102 can be made flatter, improving the use experience of the wearer. Moreover, the density of the pressure points 110 in the second absorption area 102 is lower, greatly improving the ventilation performance of the position, further reducing the growth of bacteria, and reducing the stuffy feeling.

[0043] In some embodiments, the spacing distance between two adjacent pressure points 110 is greater than or equal to 5 millimeters and less than or equal to 30 millimeters. Within this spacing distance range, the three-dimensional effect of the three-dimensional unit 120 formed by the surrounding pressure points 110 is better.

[0044] In some embodiments, the diameter of each pressure point 110 is greater than or equal to 1 millimeter and less than or equal to 3 millimeters. When the diameter of the pressure point 110 is set within this range, the three-dimensional effect of the three-dimensional unit 120 formed by the surrounding pressure points 110 is better, taking into account the thinness, diffusivity, and absorbency of the absorbent body 100.

[0045] In some embodiments, the diameters of each pressure point 110 are the same, which can facilitate the processing and production of the absorbent body 100 more conveniently. It is only necessary that the diameters of the mechanical pressure rods used to form the pressure points 110 are consistent, which is beneficial to improving the production and processing efficiency.

[0046] Preferably, the diameter of each pressure point 110 is 2 millimeters, and the three-dimensional effect achieved by each three-dimensional unit 120 is better.

[0047] It can be understood that the absorbent body 100 extends in the front-rear direction as a whole. In this embodiment, the left and right edges of the absorbent body 100 are arc-shaped, and the middle parts of the left and right edges of the absorbent body 100 are recessed toward the center of the absorbent body 100, that is, the left edge of the absorbent body 100 is recessed to the right, and the right edge of the absorbent body 100 is recessed to the left.

[0048] With such a setting, it is more adaptable to the physiological structure of the user. When in use, the absorbent body 100 is located between the two thighs of the user. Since the left and right edges of the absorbent body 100 are recessed toward the center, it can prevent the left and right edges of the absorbent body 100 from contacting the inner thighs of the user and cutting the skin of the user, thereby improving the comfort of use.

[0049] In this embodiment, the front edge of the absorbent body 100 is connected to the left and right edges through an arc edge transition, and the rear edge of the absorbent body 100 is also connected to the left and right edges through an arc edge transition. With such a setting, it can prevent the sharp tips on the absorbent body 100 from cutting the skin of the user, bringing a better use experience to the user.

[0050] In this embodiment, the rear edge of the absorbent body 100 is longer than the front edge of the absorbent body 100. With such a setting, the area at the rear of the absorbent body 100 is larger, which can reduce the occurrence of side leakage from the rear, and can also play a role in distinguishing the front and rear directions of the absorbent body 100.

[0051] Second aspect, an embodiment of the present utility model further provides a sanitary napkin, which includes an absorbent body 100 as proposed in any one of the embodiments in the first aspect. It can be understood that, since the absorbent body 100 is provided in the sanitary napkin, while maintaining thinness, it can ensure the liquid absorption performance and diffusion performance of the sanitary napkin, and reduce the risk of liquid leakage.

[0052] In some embodiments, the sanitary napkin further includes a water-locking layer and a waterproof bottom layer. The lower surface of the absorbent body 100 is connected to the upper surface of the water-locking layer, and the lower surface of the water-locking layer is connected to the upper surface of the waterproof bottom layer. During the processing, the absorbent body 100, the water-locking layer, and the waterproof bottom layer are stacked in sequence from top to bottom, and a mechanical pressing rod is used to apply pressure from top to bottom to press and connect the absorbent body 100, the water-locking layer, and the waterproof bottom layer. The pressing points 110 formed on the absorbent body 100 are squeezed downward to the water-locking layer and the waterproof bottom layer. With such a setting, the connection stability of the entire sanitary napkin can be improved, and the inconvenience caused by the looseness of each structure can be avoided for the user.

[0053] It can be understood that the sanitary napkin can be a daily-use sanitary napkin, a night-use sanitary napkin, a panty liner, etc., and no specific limitation is made here.

[0054] Third aspect, an embodiment of the present utility model further provides a sanitary pants, which includes an absorbent body 100 as proposed in any one of the embodiments in the first aspect. It can be understood that, since the absorbent body 100 is provided in the sanitary pants, while maintaining thinness, it can ensure the liquid absorption performance and diffusion performance of the sanitary pants, and reduce the risk of liquid leakage.

[0055] In this embodiment, the sanitary pants further include a trouser body, and the trouser body has two leg openings, and the absorbent body 100 is disposed at a position between the two leg openings.

[0056] It can be understood that the sanitary pants also include a water-locking layer and a waterproof bottom layer. The absorbent body 100, the water-locking layer, and the waterproof bottom layer are arranged in sequence from top to bottom, which can achieve a better water-locking effect and prevent liquid leakage. Of course, in some embodiments, if the trouser body is made of a waterproof material, then the waterproof bottom layer of the sanitary pants can be omitted, and the setting of the waterproof bottom layer in such sanitary pants can achieve a double waterproof effect.

[0057] It can be understood that during the process of arranging the absorbent body 100, the left and right sides of the waist of the sanitary pants are in a separated state. After stacking the absorbent body 100, the water-locking layer, and the waterproof bottom layer on the trouser body in sequence from top to bottom, a mechanical pressing rod is used to apply pressure from top to bottom to press and connect the absorbent body 100, the water-locking layer, and the waterproof bottom layer. The pressing points 110 formed on the absorbent body 100 are squeezed downward to the water-locking layer, the waterproof bottom layer, and the trouser body. With such a setting, the connection stability of the entire sanitary pants can be improved, and the inconvenience caused by the looseness of each structure can be avoided for the user.

[0058] It can be understood that the length of the absorber 100 can be set according to the size of the pants body, and no specific limitation is made here.

[0059] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments.
