Description

TECHNICAL FIELD

[0001] The utility model relates to sanitary article technical field, concretely relates to a sanitary article liquid absorption structure, light incontinence towel and sanitary towel. BACKGROUND

[0002] Light incontinence is more common in the elderly and postpartum women, and urine is uncontrollably discharged from the urethra under some conditions of increased intra-abdominal pressure, resulting in odor, dampness, and thus affecting normal life. Light incontinence towel is a disposable absorbent sanitary article for light incontinence groups, and the core is mainly composed of wood pulp and high-absorbent polymers for urine. When used, it is like a sanitary towel and is used by being padded on the underpants. Light incontinence towel is light, comfortable, portable, and not as heavy as adult paper diapers, and is suitable for use by light incontinence groups who are currently troubled by urine leakage.

[0003] The existing light incontinence towel is more different from ordinary sanitary towels in the formula of the absorption core, and has problems such as slow absorption of urine, poor flow guiding effect, poor air permeability, and small absorption capacity. During use, the ordinary light incontinence towel expands locally after absorbing urine, causing discomfort, hot contact, and easy breeding of bacteria, thus forming odor and even causing physiological diseases.

[0004] For example, the utility model patent with the authorization announcement number CN220558184U discloses a light incontinence water-absorbing towel. The water-repellent layer is provided with a surface layer wrapped after being folded and bonded, a bacteriostatic layer, a flow guiding layer, and an absorption sheet layer, so that the water-repellent layer and the wrapped absorption sheet layer form a suspended core structure with a three-dimensional guard on the bottom film layer. At the same time, the water-repellent layer used for wrapping is directly made of high-elasticity non-woven fabric, which is free of rubber band assembly, soft and comfortable, and the deformation of the wing when it is folded back is mostly retained in the gap between the water-repellent layer and the bottom film layer, which can better avoid the deformation of the absorption sheet layer wrapped by the water-repellent layer, improve comfort, ensure water absorption effect, and better prevent side leakage. In addition, the scheme also sets a bacteriostatic layer to reduce bacterial growth.

[0005] The above-mentioned disclosed scheme adopts a suspended core structure with a three-dimensional guard, which can achieve good side leakage prevention effect. However, urine is different from menstrual blood in that it has almost no viscosity and flows fast. The range between the three-dimensional guards of the existing light incontinence water-absorbing towel is relatively large, and urine is difficult to be immediately absorbed, which can eventually cause the user to feel damp in a short time. In addition, after absorbing urine, local swelling can easily occur, thus causing the above-mentioned discomfort and other problems. UTILITY MODEL CONTENTS

[0006] The utility model provides a sanitary article liquid absorption structure, light incontinence towel and sanitary towel to solve the technical problem of local swelling of the light incontinence towel in the prior art after absorbing urine, which causes discomfort.

[0007] To solve the above problems, the sanitary product liquid absorption structure provided by the utility model adopts the following technical scheme: an absorption body extending in the front-back direction, a surface layer arranged on the upper surface of the absorption body and contacting the skin, and a back layer arranged on the lower surface of the absorption body;

[0008] The absorption body is provided with inner and outer pressure lines for connecting the absorption body, the surface layer and the back layer, the inner and outer pressure lines are concentrically arranged and are both annular, the inner and outer pressure lines compress the absorption body in the thickness direction, force the surface layer to press the absorption body, and form a raised barrier ring between the inner and outer pressure lines, and a containing cavity for storing liquid and reducing liquid leakage is formed on the inner side of the barrier ring.

[0009] The surface layer above the barrier ring presses the barrier ring, the density of the top of the barrier ring is greater than that of the bottom of the barrier ring, so as to delay the penetration of the liquid to the top of the barrier ring.

[0010] As a further improvement, a drainage layer is arranged between the absorption body and the surface layer for drainage, so as to accelerate the diffusion and absorption of the liquid.

[0011] As a further improvement, the drainage layer is blue cotton, the blue cotton is arranged on the inner side of the barrier ring and extends outwardly between the inner and outer pressure lines, and the shape of the blue cotton is the same as the contour of the inner pressure line or the contour of the outer pressure line.

[0012] As a further improvement, the inner side of the barrier ring is further provided with a pressure line strip for compressing the absorption body in the thickness direction.

[0013] As a further improvement, the cross section of the barrier ring is in the shape of a concave character.

[0014] The utility model also provides a light incontinence pad, the light incontinence pad has the above-mentioned sanitary product liquid absorption structure.

[0015] The utility model also provides a sanitary napkin, the sanitary napkin has the above-mentioned sanitary product liquid absorption structure.

[0016] The beneficial effects of the above technical scheme of the utility model are as follows:

[0017] 1, the utility model discloses a inner pressure line and outer pressure line are set up, make the upper surface of absorption body form the raised barrier ring, make the product and the recessed part of female private parts present "concave", the recessed part can guarantee that the product and the recessed part are not close contact, can effectively reduce the discomfort caused by the product and the recessed part rubbing when the user walks.

[0018] 2, the containing cavity is formed on the inner side of the barrier ring, the containing cavity can contain urine, reduce the diffusion of urine to the surrounding, and the urine in the containing cavity penetrates to the bottom and is quickly guided to the surrounding absorption body by the blue cotton.

[0019] 3. Due to the compression of the inner and outer pressure lines, the surface layer presses downwards against the barrier ring, making the density of the top of the barrier ring greater than that of the bottom of the barrier ring. When urine permeates, it will preferentially permeate into the fluffy area of ​​the absorbent body, and the urine will finally permeate into the top of the barrier ring with a higher density. This ensures that the top of the barrier ring, which is in direct contact with the skin, can remain dry for a long time.

[0020] 4. After absorbing urine once, the raised barrier ring will bulge even higher, creating reverse absorption. This allows urine and other bodily fluids to be continuously absorbed outwards without backflow. During the second or even third urine absorption, the product's absorption rate will be faster than the first absorption, better ensuring the user's intimate area remains dry. Furthermore, the raised barrier ring further reduces contact between the female genitalia and the product. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] The existing incontinence pads have a structure similar to that of regular sanitary napkins. However, urine is different from blood. Urine is almost non-sticky and flows quickly, while the existing incontinence pads absorb urine relatively slowly. During use, regular incontinence pads absorb urine and then swell locally, causing discomfort, stuffiness at the contact area, and easy growth of bacteria, which can lead to odor and even physiological diseases.

[0029] To address the aforementioned issues, this invention creates an inner and outer embossed line, forming a raised barrier ring 2 on the upper surface of the absorbent body 1. On one hand, the recessed area of ​​the barrier ring 2 ensures that the product does not come into close contact with the private parts, effectively reducing discomfort caused by friction between the product and the private parts when the user moves around. On the other hand, the recessed area inside the barrier ring 2 forms a urine storage cavity 3, and the blue cotton 10 at the bottom of the storage cavity 3 can quickly drain the urine, allowing it to quickly penetrate into the absorbent body 1 and be absorbed by it.

[0030] In addition, since the barrier ring 2 is formed by compression through inner and outer pressure lines, the absorbent material at the top of the barrier ring 2 has a relatively higher density after being squeezed. When urine permeates, it will preferentially permeate to the fluffy area of ​​the absorbent 1, and then gradually permeate to the top of the barrier ring 2. This ensures that the top of the barrier ring 2 in contact with the skin can remain dry for a long time, thereby achieving a dry effect.

[0031] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0032] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0033] Example 1 of the liquid absorption structure for hygiene products provided by this utility model:

[0034] like Figure 1 and Figure 2As shown, the absorbent includes an absorbent body 1 extending in the front-to-back direction, a surface layer 4 disposed on the upper surface of the absorbent body 1 in contact with the skin, and a back layer 5 disposed on the lower surface of the absorbent body 1. In this embodiment, the absorbent body 1 includes a cotton core 6 and a superabsorbent polymer 7 (SAP). The surface layer 4 and the back layer 5 are both non-woven fabric products. The materials of the absorbent body 1, the surface layer 4, and the back layer 5 can be adjusted and replaced as needed. In addition, other surface layers can be added as needed. For example, a conductive layer 11 can be added inside the absorbent body 1 to allow urine to quickly penetrate to the front and back sides of the absorbent body 1.

[0035] The absorber 1 is provided with inner and outer embossed lines for connecting the absorber 1, the surface layer 4, and the back layer 5. The outer embossed line is L1 in the figure, and the inner embossed line is L2 in the figure. The inner and outer embossed lines are concentrically arranged and are both annular. The inner and outer embossed lines compress the absorber 1 in the thickness direction, forcing the surface layer 4 to squeeze the absorber 1, so that a raised barrier ring 2 is formed between the inner and outer embossed lines. The inner side of the barrier ring 2 forms a receiving cavity 3 for storing liquid and reducing liquid leakage; Figure 2 As shown, the cross-section of the barrier ring 2 is U-shaped.

[0036] The raised barrier ring 2 makes the contact area between the product and the female private parts concave. The concave area ensures that the product does not make close contact with the private parts, which can effectively reduce the discomfort caused by the product rubbing against the private parts when the user walks. The inner side of the barrier ring 2 forms a receiving cavity 3, which can hold urine and reduce the spread of urine to the surrounding area. The urine in the receiving cavity 3 permeates to the bottom and is quickly guided to the surrounding absorbent body 1 by the blue cotton 10.

[0037] The shape of the barrier ring 2 is determined by the inner and outer embossed lines. The shape of the barrier ring 2 can be olive-shaped, heart-shaped, or other shapes that fit the female private parts.

[0038] The surface layer 4 above the barrier ring 2 presses against the barrier ring 2, making the density of the top of the barrier ring 2 (i.e., the area above the dotted line L3 in the figure) greater than the density of the bottom of the barrier ring 2, so as to delay the liquid from penetrating to the top of the barrier ring 2, thereby ensuring that the top of the barrier ring 2 remains dry for a long time, giving the user a dry feeling.

[0039] Blue cotton 10 is located above absorbent 1. Blue cotton 10 is used to guide urine to the surrounding area. Specifically, blue cotton 10 is set inside the barrier ring 2 and extends outward to the area between the inner and outer pressure lines. The shape of blue cotton 10 is the same as the outline of the inner or outer pressure lines.

[0040] The inner side of the barrier ring 2 is also provided with embossed strips for compressing the absorber 1 in the thickness direction. Figure 2In section L4, the embossed strip can be a continuous line structure or a series of spaced-apart dot structures. The embossed strip reduces the thickness of the absorbent body 1 inside the barrier ring 2, minimizing contact between the absorbent body and the female genitalia. Simultaneously, the small annular protrusions formed between the inner embossed lines and the embossed strip increase the contact area between urine and the surface layer such as the cotton, accelerating the downward flow of urine. When the amount of urine is small, the small annular protrusions can also effectively block urine and reduce its flow.

[0041] When urine flows onto a product, the warm and humid environment easily leads to bacterial growth, resulting in an unpleasant odor. Urine also contains ammonia and other odor-causing substances. This invention incorporates a superabsorbent polymer 7 (7) within the absorbent body 1, which has antibacterial and deodorizing properties (functional additives can also be added to the conductive layer to achieve the same function). The barrier ring 2 reduces contact between the female genitalia and the product, promoting air circulation. Together, these elements inhibit bacterial growth, reduce odor, and protect the health of the female genitalia. Furthermore, the product reduces odor through adsorption and reaction with ammonia molecules. Mild urinary incontinence can lead to a lack of self-confidence, affecting normal life and social interactions, and even causing psychological stress. Based on Maslow's hierarchy of needs, this invention can satisfy the social and esteem needs of individuals with mild urinary incontinence. Example 2

[0042] Its main difference from Example 1 is:

[0043] In Example 1, the absorber 1 is provided with inner embossed lines and outer embossed lines for connecting the absorber 1, the surface layer 4 and the back layer 5. The inner embossed lines and outer embossed lines are concentrically arranged and are both annular. The inner embossed lines and outer embossed lines compress the absorber 1 in the thickness direction, forcing the surface layer 4 to squeeze the absorber 1, so that a raised barrier ring 2 is formed between the inner embossed lines and the outer embossed lines.

[0044] In this embodiment, the barrier ring 2 is formed by compressing the inner and outer embossed lines, which results in a relatively lower processing cost.

[0045] In this embodiment, a cotton ring is separately provided on the upper surface of the absorbent 1 (the cotton ring is made of cotton core 6 and superabsorbent polymer (SAP), and the material of the cotton ring is the same as that of the absorbent 1). Then, the surface layer 4 is covered on the absorbent 1 and the cotton ring and fixed by inner and outer embossing lines. The raised cotton ring forms a barrier ring 2.

[0046] In this embodiment, the height of the protrusion of the barrier ring 2 can be set higher, but correspondingly, its production cost will increase. Example 3

[0047] This embodiment provides a light incontinence napkin, which has the liquid-absorbing structure of the above-mentioned sanitary products.

[0048] The structural diagram of the light incontinence towel is as follows: Figure 3 As shown, the structure includes, from top to bottom, a 3D surface nonwoven fabric 13 (made of double-layer hot-air nonwoven fabric), a surface nonwoven fabric 12, blue cotton 10, a conductive layer 11, an upper layer of toilet paper 9, a cotton core 6 (with superabsorbent polymer 7 added inside), a lower layer of toilet paper 8, a bottom film 15, a back wing release paper 17, a small wrap film 19, and a quick-release wing 18. The upper surface of the 3D surface nonwoven fabric 13 also has two sides of nonwoven fabric 14, with elastic bands 20 inside each side. The back wing release paper 17 also has protective wing release paper 16 on its sides. Specifically, both the 3D surface nonwoven fabric 13 and the surface nonwoven fabric 12 are made of hot-air nonwoven fabric. It should be noted that... Figure 3 Neither the inner nor outer embossing lines are drawn; their specific locations can be found in [reference needed]. Figure 1 and Figure 2 . Example 4

[0049] This utility model also provides a sanitary napkin, which has the liquid absorption structure of the above-mentioned sanitary products.
