Description

Technical Field

[0001] This utility model relates to the field of absorbent products, specifically to absorbent products such as sanitary napkins, panty liners, and diapers. Background Technology

[0002] Sanitary napkins, panty liners, diapers, and other absorbent products are widely used in people's daily lives. However, existing absorbent products often encounter odor problems when worn for extended periods.

[0003] In response, several patent documents have been proposed, such as CN213883824U (titled "An antibacterial and deodorizing sanitary napkin"), CN219109974U (titled "A moisture-absorbing diaper or pad that can reduce odor"), and CN219662087U (titled "A deodorizing sanitary napkin"), which suggest placing adsorbent materials such as activated carbon above or below the absorbent layer to reduce odor. However, in practice, it has been found that placing adsorbent materials directly above or below the absorbent layer can easily affect the absorption rate of the absorbent product. In other studies, such as CN221672342U, it is proposed to place the odor adsorption layer in the position of the main absorption area to simultaneously satisfy high absorbency and effective adsorption of odor.

[0004] Other studies have found that substances such as bamboo quinone can remove odors by reacting with them. Bamboo quinone also has antibacterial effects. However, bamboo quinone has low volatility. Therefore, on the one hand, the product needs to have good adsorption performance, and on the other hand, these substances need to come into contact with odors or body fluids to achieve the effects of removing odors and sterilizing. On the other hand, it is necessary to overcome the problem of decreased absorption performance caused by arranging the substances in the main absorption area in the existing technology.

[0005] Therefore, there is a need to provide an absorbent product that has both good odor removal capabilities and good absorption performance. Utility Model Content

[0006] Therefore, this utility model provides an absorbent product to solve the above-mentioned technical problems.

[0009] The convex section is further provided with a first concave section and a second concave section on both sides, wherein the first concave section and the second concave section are symmetrically arranged.

[0010] The minimum distance between the first concave section and the second concave section and the edge line is 3 to 12 mm.

The first center line is defined as the line connecting the center points of the indentations on the first linear embossing, and the second center line is defined as the line connecting the center points of the indentations on the second linear embossing. The first linear embossing and the second linear embossing include an intersection area and an interval area. In the intersection area, there is a first virtual straight line that is tangent to both the first center line and the second center line.

[0015] In the interval region, the spacing between the first linear embossing and the second linear embossing gradually increases and then gradually decreases.

[0016] Wherein, the linear embossing group is arranged in a linear array along an inclined straight line, the second virtual straight line is defined as the inclined straight line, and the third virtual straight line is defined as a straight line extending along the width direction of the body, then the included angle between the second virtual straight line and the third virtual straight line is 40° to 75°.

Detailed Implementation

[0024] This utility model provides an absorbent product, which will be further described below with reference to the accompanying drawings.

[0025] It should also be noted that the terms "upper," "lower," "inner," "outer," and "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Please refer to the attached document. Figure 1-5 The absorbent material provided in this application includes a body 10, which includes a top layer 11, an absorbent layer 13, and a bottom layer 14.

[0027] The body 10 is generally strip-shaped, including both the length and width directions. Figure 1 The length direction is vertical and the width direction is horizontal. The main body 10 includes a main absorption area 20. Typically, the main absorption area 20 is located in the middle of the main body 10, and the main absorption area 20 is the area corresponding to the body fluid excretion area, so that the main absorption area 20 can more easily absorb body fluid.

[0028] Understandably, the absorbent material also includes wings, which are usually located on the left and right sides of the main absorbent area 20. Typically, the wings protrude from the body 10 and can be folded back and attached to the underwear.

[0029] The surface layer 11 is disposed on the side close to the user's skin, and the surface layer 11 should be at least partially liquid-permeable. Liquid permeability means that body fluids can pass through the surface layer 11 and enter the structural layer below the surface layer 11, such as the absorbent layer 13. Typically, the body fluids can also diffuse along the surface layer 11 to further improve the absorption efficiency of the absorbent for body fluids.

[0030] The phrase "at least part of the liquid is permeable" means that at least the area of ​​the surface layer 11 corresponding to the fluid discharge area is permeable, and the fluid discharge area can be the vaginal opening, urethral opening, or other similar locations.

[0031] Since the surface layer 11 comes into contact with the skin, it is preferably made of a material that is low in irritation and soft, such as having a weight per unit area of ​​10–60 g / m². 2Sheet 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 can also be added at the same time to further reduce skin irritation. These natural fibers can include wood fibers, cotton fibers, etc.

[0032] The absorbent layer 13 is stacked below the surface layer 11. Specifically, the absorbent layer 13 is a three-dimensional network structure formed by several entangled fibers appropriately connected. Several pores are distributed between the three-dimensional network structure, through which body fluids can be absorbed and diffused. In a preferred embodiment, superabsorbent polymer (SAP) is included between the three-dimensional network structure to further absorb and retain body fluids through the superabsorbent polymer. It is understood that the fibers can be fluff pulp.

[0033] Furthermore, the absorbent layer 13 may also include a covering layer, which covers or coats the three-dimensional network structure. The covering layer is a liquid-permeable material; in some specific embodiments, it may be non-woven fabric or toilet paper. Preferably, the covering layer is soft, for example, having a weight per unit area of ​​10–60 g / m². 2 Sheet materials such as gauze, cotton cloth, spunlace nonwoven fabric, hot air nonwoven fabric, and toilet paper are preferred, and more preferably, the covering layer has a lower basis weight than the surface layer 11.

[0034] The bottom layer 14 is stacked below the absorbent layer 13. In order to prevent body fluids from seeping through the surface layer 11 and contaminating the user's clothing, the bottom layer 14 is usually made of water-repellent material. Specifically, it can be PE film, SMS non-woven fabric, non-woven fabric with water-repellent treatment, etc. Preferably, the bottom layer 14 allows gas, such as water vapor, to pass through, but body fluids cannot pass through, so that it will not be stuffy when used.

[0035] The surface layer 11 and the bottom layer 14 are joined along the edge of the body 10 so that the surface layer 11 and the bottom layer 14 are joined to form an outer peripheral portion, and the surface layer 11 and the bottom layer 14 are arranged along the outer peripheral portion to form an accommodating space. The absorbent layer 13 is accommodated in the accommodating space. The joining refers to the connection of the joined materials to form a whole. Usually, it can be formed by hot melting or bonding. The hot melting can be achieved by heating the material itself to the melting point temperature, then locally melting and solidifying to form a connection, or by applying external energy such as ultrasound to the material to locally generate high temperature melting and solidify to form a connection. The bonding can be achieved by using an adhesive to connect adjacent materials under the action of the adhesive.

[0036] The main absorption area 20 is surrounded by a main flow channel. More specifically, the main flow channel includes a first flow channel 21 and a second flow channel 22 symmetrically arranged along the width direction of the body 10. The first flow channel 21 and the second flow channel 22 are both formed by a plurality of adjacent flow-guiding indentations 201 forming a roughly linear embossed pattern. The flow-guiding indentations 201 on the body 10 are recessed grooves extending from the upper surface of the surface layer 11 towards the bottom layer 14. The upper surface is the surface of the surface layer 11 facing the user's skin. Meanwhile, the flow-guiding indentations 201... 01 The shape of the indentation 201 on the upper surface can be either dot-shaped or line-shaped. When the aspect ratio of the indentation 201 is less than or equal to 5, it appears as a dot-shaped indentation. When the aspect ratio of the indentation 201 is greater than 5, it appears as a line-shaped indentation. In addition, when the indentation 201 is recessed from the surface layer 11 to the bottom layer 14, it combines with the surface layer 11 and the absorption layer 13. It can be understood that the indentation 201 combines with the surface layer 11 and the absorption layer 13 in a mechanical way. Through this combination, the surface layer 11 and the absorption layer 13 can maintain the combined state under the action of no external force.

[0037] In the main absorption zone 20, an adsorption layer 12 is provided between the surface layer 11 and the absorption layer 13. The adsorption layer 12 includes a deodorizing agent. Specifically, the deodorizing agent can be a masking agent, an adsorbent, or a neutralizing agent.

[0038] The masking agent is configured to release volatile substances to mask odors. These volatile substances can be fragrances. The adsorbent is a porous particulate material. Its principle is that the surface of the adsorbent has highly absorbent pores with a large surface area, allowing it to fully contact and adsorb odor molecules. The adsorbent can be selected from at least one of activated carbon, diatomaceous earth, and porous calcium phosphate. The neutralizing agent can be bamboo quinone, which reacts with odor molecules to eliminate them. Furthermore, when bamboo quinone is used as the deodorizing agent, it can also produce an antibacterial effect. Of course, an antibacterial agent can also be provided on the adsorption layer.

[0039] It is understood that the adsorption layer 12 includes a base layer, and the deodorizing agent can be applied to the base layer by means of impregnation, coating, sprinkling, or bonding.

[0040] Understandably, the base layer can be a porous network structure made of fibers.

[0041] The adsorption layer 12 includes an edge line 1201 facing the first guide channel 21. The edge line 1201 is separated from the first guide channel 21. The first guide channel 21 is wavy on the surface layer 11 and includes an outwardly protruding section 212 that protrudes away from the adsorption layer 12. It can be understood that an outwardly protruding area 214 is formed between the outwardly protruding section 212 and the edge line 1201. This arrangement makes the outwardly protruding area 214 form a slight cavity area. When the absorbent is used, this area is slightly raised, which provides a better tactile feel, forms a slight fluid containment area and allows the fluid to be quickly diffused by the first guide channel 21, and makes it easier for gas to enter or even create a breathing effect during use so that the gas can enter and be removed by the deodorizing agent on the adsorption layer 12.

[0042] Furthermore, a first concave section 211 and a second concave section 213 are respectively provided on both sides of the convex section 212, wherein the first concave section 211 and the second concave section 213 are symmetrically arranged.

[0043] Furthermore, the minimum distance between the first concave segment 211 and the second concave segment 213 and the edge line 1201 is 3 to 12 mm.

[0044] Furthermore, the main flow channel also includes a third flow channel 23 and a fourth flow channel 24 arranged along the length of the body 10. The first flow channel 21, the third flow channel 23, the second flow channel 22 and the fourth flow channel 24 are connected end to end, forming a generally closed area. It can be understood that the closed area is the main absorption area 20.

[0045] The surface layer 11 also includes several linear embossings formed by adjacent arrangement of surface indentations 1101. On the one hand, this makes the surface layer 11 have a better tactile feel. On the other hand, by setting the linear embossings formed by adjacent arrangement of surface indentations 1101 on the surface layer 11, the surface layer 11 presents a form of alternating density. More specifically, this reduces the fiber porosity of the surface layer material at the position corresponding to the surface indentation 1101, increasing capillary action, while increasing porosity in the area adjacent to the surface indentation. However, because the surface layer fibers are finer, gas can easily pass through the surface layer. The increased capillary action at the position corresponding to the surface indentation 1101 allows body fluid to quickly pass through the surface layer 11 when it seeps out. At the same time, when adsorbing gas, the gas can also quickly pass through the surface layer 11, thereby achieving both a better absorption effect and an adsorption effect on odors.

[0046] Furthermore, the surface indentation 1101 is a point-to-flat indentation, meaning that the surface indentation 1101 has a concave shape on one side and a flat shape on the other side. It can be understood that the side with the concave shape is the side facing the skin. It can be understood that the surface indentation 1101 should only be set on the surface layer 11. It means that the surface indentation 1101 does not form a groove for the absorption layer 13 or adsorption layer 12 located below the surface layer 11. In addition, the surface indentation 1101 should be smaller than the flow-guiding indentation 201. It means that the length, width and depth of the surface indentation are all smaller than the flow-guiding indentation.

[0047] Furthermore, the linear embossing is fully laid out on the surface layer 11.

[0048] Please refer to this as well. Figure 4 and Figure 5 The linear embossing appears as wavy lines on the surface of the surface layer 11. In this embodiment, the linear embossing is arranged in a linear array of linear embossing groups 111. More specifically, the linear embossing group 111 includes a pair of linear embossings. For easier description, the pair of linear embossings constituting the linear embossing group 111 are referred to as the first linear embossing 1111 and the second linear embossing 1112, respectively. The first linear embossing 1111 and the second linear embossing 1112 have the same form. The same form means that the surface indentations 1101 constituting the first linear embossing 1111 and the second linear embossing 1112 have the same shape, size, and arrangement.

[0049] Furthermore, the first center line 1113 is defined as the line connecting the center point of the indentation 1101 on the first linear embossing 1111, and the second center line 1114 is defined as the line connecting the center point of the indentation 1101 on the second linear embossing 1112. The first linear embossing 1111 and the second linear embossing 1112 include an intersection area 112 and a gap area 113. Then, in the intersection area 112, there is a first virtual straight line 1120 that is tangent to both the first center line 1113 and the second center line 1114.

[0050] Furthermore, in the interval region 113, the spacing between the first linear embossing 1111 and the second linear embossing 1112 gradually increases and then gradually decreases.

[0051] Furthermore, the linear embossing group 111 is arranged in a linear array along an inclined straight line. The second virtual straight line 114 is defined as the inclined straight line, and the third virtual straight line 115 is defined as a straight line extending along the width direction of the body 10. The included angle between the second virtual straight line 114 and the third virtual straight line 115 is 40° to 75°.

[0052] 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.
