Description

Technical Field

[0001] The utility model relates to the technical field of sanitary products, and particularly relates to a light incontinence towel with a leak-proof flexible side edge. Background Art

[0002] Light incontinence usually refers to mild urinary incontinence, which means that urine will involuntarily flow out when the patient is in certain specific situations, such as coughing, sneezing or doing slight exercise. For patients with mild incontinence, incontinence care products such as light incontinence towels or light incontinence pads can be used to assist in the discharge of urine in daily life and improve their quality of life. Incontinence care products usually need to have functions such as absorption ability, comfort, and leak prevention. The absorption core of incontinence care products can refer to products such as sanitary napkins and diapers to achieve good absorption ability, and the incontinence care products need to be provided with a side edge structure that can block or absorb liquid to achieve the leak-proof function. At present, the side edge structures of some incontinence care products will squeeze positions such as the root of the human thigh. Although it can achieve a good leak-proof effect, it reduces the comfort of the incontinence care products.

[0003] Chinese Patent with publication number CN219070982U discloses a disposable light incontinence towel, which includes a non-woven bottom film. An adhesive cloth is fixedly arranged on the top of the non-woven bottom film. Adhesive strips are fixedly arranged at both ends of the top of the adhesive cloth. A shaping cushion layer is fixedly arranged on the top of the non-woven bottom film. A positioning water-absorbing layer is fixedly arranged on the top of the shaping cushion layer. A diversion layer is fixedly arranged on the top of the positioning water-absorbing layer. A skin-friendly layer is fixedly arranged on the top of the diversion layer. An absorption cotton is fixedly arranged in the middle of the top of the skin-friendly layer. A flange is integrally arranged on the side of the top of the skin-friendly layer. An oil paper layer is arranged outside the flange. An inner absorption strip is fixedly arranged inside the flange. Both sides of the absorption cotton are connected with the inner absorption strip. After the above-mentioned light incontinence towel absorbs liquid through the absorption cotton, the liquid is diffused into the flange. After the inner absorption strip inside the flange absorbs the liquid, the flange expands and bulges, which can achieve the effect of leak prevention. However, after the flange expands and bulges, it is specifically manifested as an increase in the thickness on both sides in the width direction of the light incontinence towel, and these two sides are located at the position of the root of the human thigh. The bulged flange will squeeze the root of the human thigh, which will cause the user to feel obvious foreign body sensation and affect the user's normal activities such as walking, thereby reducing the use comfort. Therefore, there is still room for improvement in this disposable light incontinence towel. Summary of the Utility Model

Specific implementation manner

[0028] The following combines the drawings and related embodiments to illustrate the implementation manner of the present utility model. The implementation manner of the present utility model is not limited to the following embodiments, and the relevant necessary components of the present utility model in the technical field should be regarded as well-known technologies in the technical field, which can be known and mastered by those skilled in the technical field.

[0029] As Figure 1 、 2 shown, a light incontinence towel with a leak-proof flexible side border includes an absorption area 1 and a flexible side border 2. The width direction of the absorption area 1 is defined as the transverse direction, and the length direction is defined as the longitudinal direction. The absorption area 1 is composed of a surface layer 11, an absorption core 12, and a bottom film 13 from top to bottom. The flexible side border 2 is located at the transverse two ends of the absorption area 1 and extends along the longitudinal direction; the flexible side border 2 includes the following structure: a wrapping layer 21, which is folded down from the edge of the surface layer 11 to the lower surface of the bottom film 13 and adhered to the lower surface of the bottom film 13. A wrapping cavity is formed between the top and bottom of the wrapping layer 21. A composite structure layer 22 extending along the longitudinal direction is provided in the wrapping cavity. The composite structure layer 22 is composed of a first side border interlayer 221, an elastic layer 222, and a second side border interlayer 223 from top to bottom. The two transverse ends of the first side border interlayer 221 are adhered to the top of the wrapping layer 21, so that a first cavity is formed between the top of the wrapping layer 21 and the first side border interlayer 221. The elastic layer 222 is composed of at least one elastic spandex yarn 2221 extending along the longitudinal direction; the top of the wrapping layer 21 is located above the composite structure layer 22, and the bottom of the wrapping layer 21 is located below the composite structure layer 22; at least one of the wrapping layer 21 and the first side border interlayer 221 has water repellency.

[0030] The light incontinence towel of the present utility model is used to assist patients with mild incontinence in managing the discharge of urine in daily life. The surface layer 11 in the absorption area 1 is a structure close to the human genital organ and is in direct contact with the human genital organ. The surface layer 11 is made of hot air non-woven fabric or spunlace non-woven fabric, and the gram weight of the non-woven fabric is 3-35 gsm. Both of these non-woven fabrics have good softness, air permeability and water absorption, which can make the surface of the light incontinence towel have a good touch and improve the use comfort. In addition, when the user's urine is discharged during incontinence, it first contacts the surface layer 11. The surface layer 11 quickly absorbs the urine through good water absorption and penetrates it into the absorption core 12, and keeps the surface dry through good air permeability, further improving the use comfort of the light incontinence towel.

[0031] The absorption core 12 in the absorption area 1 is composed of an outer non-woven fabric wrapping an internal absorption material. Among them, the outer non-woven fabric is preferably spunbond non-woven fabric. The spunbond non-woven fabric has good mechanical strength, which can ensure the structural stability of the absorption core 12. At the same time, the side of the absorption core 12 close to the surface layer 11 is more preferably SSS spunbond non-woven fabric. The SSS spunbond non-woven fabric can quickly absorb and spread liquids, and can also prevent liquid backflow. When the urine is absorbed by the surface layer 11 and penetrates into the absorption core 12, it will first contact the SSS spunbond non-woven fabric. The SSS spunbond non-woven fabric will quickly spread the urine into the internal absorption material and be absorbed; in addition, the absorption material is selected from one or more of fluff pulp, water-absorbing resin, and viscose fiber. These materials all have good water absorption and firmly lock the absorbed liquid, ensuring the absorption performance of the light incontinence towel and preventing the absorbed urine from generating backflow.

[0032] The bottom film 13 in the absorption area 1 is preferably a polyethylene breathable film. During the production process of the polyethylene breathable film, a lot of micropores that allow gas to pass through and do not allow liquid to pass through are formed by stretching, improving the air permeability of the light incontinence towel and avoiding the liquid penetrating through the bottom film 13 and seeping to the surface of the light incontinence towel, keeping the surface of the light incontinence towel dry.

[0033] The flexible partition edges 2 of the utility model are arranged at the two transverse ends of the absorption area 1. When the user uses the light incontinence towel, the two flexible partition edges 2 are just located at the position of the human body's thigh roots. The flexible partition edges 2 are provided with a composite structure layer 22 which is bonded in sequence by a first partition interlayer 221, an elastic layer 222, and a second partition interlayer 223. The elastic layer 222 is composed of at least one elastic spandex yarn 2221 extending in the longitudinal direction and has tensile elasticity. During the bonding process of the composite structure layer 22, the elastic layer 222 is in a stretched state. The bonding method includes but is not limited to one of the currently commonly used adhesive bonding, thermal bonding, and ultrasonic bonding. After the bonding is completed, the elastic layer 222 shrinks to form a plurality of wrinkles on the upper surface and the lower surface of the composite structure layer 22. After the wrapping layer 21 is bonded and fixed to the edge of the surface layer 11, it is folded from the upper surface of the composite structure layer 22 to the lower surface to wrap the composite structure layer 22. The wrapping layer 21 and the surface layer 11 are bonded and fixed to the surface layer 11, and the composite structure layer 22 is wrapped. The composite structure layer 22 together constitutes the flexible partition 2. The several folds on the upper surface of the composite structure layer 22 divide the first cavity into several parts and prop it upward, so that a number of raised protrusions are formed on the top upper surface of the wrapping layer 21. The interior of these protrusions are air cavities without filling solid objects, so that the flexible partition 2 has good fluffiness and softness. The position of the incontinence towel with a flexible partition 2 can better fit the human body and improve the comfort when in contact with the human body. In addition, when the user is incontinent and the amount of urine is large, the surface layer 11 may not be able to make all the urine penetrate into the absorbent core 12 in a short time, so that the urine will flow laterally along the surface of the surface layer 11 to the flexible partition 2. Since at least one of the wrapping layer 21 and the first partition interlayer 221 is water-repellent, it prevents the urine from continuing to flow laterally and guides the urine to flow longitudinally. Therefore, the flexible partition 2 can play a good role in preventing side leakage at the thigh root.

[0034] It should be noted that the wrapping layer 21 and the first partition interlayer 221 are both non-woven fabrics. After the non-woven fabrics are manufactured and formed, a water-repellent layer is formed on the surface of the non-woven fabrics by spraying or dipping a hydrophobic coating to obtain a water-repellent non-woven fabric, thereby making at least one of the wrapping layer 21 and the first partition interlayer 221 water-repellent.

[0035] Furthermore, if Figure 3 As shown, as the second preferred embodiment of the utility model, the lateral edge of the surface layer 11 extends into the wrapping cavity to form a first partition interlayer 221, and the wrapping layer 21 is made of water-repellent non-woven fabric; the surface layer 11 and the first partition interlayer 221 are integrally formed, which can simplify the production process of light incontinence towels and increase the firmness and stability of the flexible partition 2 structure. In addition, since the surface layer 11 needs to quickly absorb urine and penetrate it into the absorbent core 12 and needs to be hydrophilic, the first partition interlayer 221 also has hydrophilicity. Therefore, the wrapping layer 21 needs to use water-repellent non-woven fabric to ensure the anti-side leakage effect of the flexible partition 2.

[0036] Furthermore, ifFigure 4 As shown in the figure, as the third preferred embodiment of the present utility model, the lateral edge of the surface layer 11 extends outward to form a wrapping layer 21, and the first partition sandwich layer 221 is made of a water-repellent non-woven fabric with a grammage of 5-11 gsm; the surface layer 11 and the wrapping layer 21 are integrally formed, which can simplify the manufacturing process of the light incontinence towel and increase the firmness and stability of the flexible partition 2 structure. In addition, since the surface layer 11 needs to quickly absorb and penetrate urine into the absorbent core 12 and needs to be hydrophilic, the wrapping layer 21 is also hydrophilic. Therefore, the first partition sandwich layer 221 needs to be made of water-repellent non-woven fabric to ensure the anti-side leakage effect of the flexible partition 2.

[0037] Furthermore, a bonding tape 3 extending longitudinally is provided at the bottom of the bottom film 13, and a release paper 4 covers the bottom of the bonding tape 3; the bonding tape 3 of the present utility model is preferably an adhesive tape. Before using the light incontinence towel, the side of the release paper 4 coated with the release agent faces the bonding tape 3 and covers the bonding tape 3 to prevent the bonding tape 3 from being contaminated by external dust and other debris and affecting its bonding ability. When the user uses the light incontinence towel, the release paper 4 is torn off and the light incontinence towel is adhered to the inner side of the crotch of the underwear through the bonding tape 3, so that the surface layer 11 of the light incontinence towel faces the human crotch for use. The bonding tape 3 firmly fixes the light incontinence towel on the underwear and prevents displacement and other situations during use.

[0038] In summary, the light incontinence towel of the present utility model is used to assist mildly incontinent patients in managing the discharge of urine in daily life. Flexible partitions 2 are provided at both lateral ends of the light incontinence towel at the root of the human thighs. Inside the flexible partitions 2, there is a composite structure layer 22 that forms several folds by the elasticity of the elastic layer 222. The composite structure layer 22 forms several protrusions with air cavities inside on the upper surface of the flexible partition 2, so that the flexible partition 2 has good fluffiness and softness. The flexible partition 2 makes the light incontinence towel more fitting and improves the use comfort. At the same time, the water-repellent property of the wrapping layer 21 or the first partition sandwich layer 221 can prevent the urine on the surface of the surface layer 11 from flowing laterally continuously, realizing the dry-wet separation of the absorption area 1 and the flexible partition 2, and the flexible partition 2 makes the light incontinence towel have a good anti-side leakage effect.

[0039] As Figure 1 、 2 shown, as one of the preferred embodiments of the present utility model, the elastic layer 222 is intermittently bonded longitudinally with the first partition sandwich layer 221 and the elastic layer 222 is intermittently bonded longitudinally with the second partition sandwich layer 223. A number of internal flexible cavities 224 are formed between the elastic layer 222 and the first partition sandwich layer 221 and between the elastic layer 222 and the second partition sandwich layer 223.

[0040] The bonding methods between the elastic layer 222 of the present utility model and the first side-separating interlayer 221, and between the elastic layer 222 and the second side-separating interlayer 223 include, but are not limited to, one of the commonly used adhesive bonding, thermal bonding, and ultrasonic bonding. After the first side-separating interlayer 221, the elastic layer 222, and the second side-separating interlayer 223 are bonded in sequence to form the composite structure layer 22, the elastic layer 222 is in a stretched state during the bonding process. Due to the method of intermittent bonding along the longitudinal direction, after the bonding is completed, the elastic layer 222 shrinks, causing the first side-separating interlayer 221 to form a number of upwardly convex inner flexible cavities 224 and the second side-separating interlayer 223 to form a number of downwardly convex inner flexible cavities 224. The main filling material inside the inner flexible cavities 224 is air, which can improve the fluffiness and softness inside the flexible side edge 2. Moreover, the inner flexible cavities 224 can well support the top upper surface of the wrapping layer 21 to form a convex part, making the surface of the flexible side edge 2 have a more comfortable touch and improving the comfort of the light incontinence towel.

[0041] As Figure 1 , 2 shown, as one of the preferred embodiments of the present utility model, the first side-separating interlayer 221 and the top of the wrapping layer 21 are intermittently bonded along the longitudinal direction, causing a number of surface layer folds to form on the top upper surface of the wrapping layer 21. The surface layer folds divide the first cavity into a number of upper flexible cavities 23.

[0042] After the first side-separating interlayer 221 and the top of the wrapping layer 21 are intermittently bonded along the longitudinal direction in the present utility model, a number of upper flexible cavities 23 are evenly formed in the first cavity. On both sides of each upper flexible cavity 23, there are bonding points formed by the intermittent bonding of the first side-separating interlayer 221 and the top of the wrapping layer 21. The bonding points can serve as the support structure for the upper flexible cavities 23 to maintain the structural stability of the upper flexible cavities 23. The inside of the upper flexible cavities 23 can be supported by the inner flexible cavities 224, further improving the structural stability of the upper flexible cavities 23. The main filling material inside the upper flexible cavities 23 is air, which can improve the softness of the upper surface of the flexible side edge 2, making the upper surface of the flexible side edge 2 have a more comfortable touch and improving the comfort of the light incontinence towel.

[0043] As Figure 1 shown, as one of the preferred embodiments of the present utility model, the lateral outer edge of the elastic layer 222 is flush with the lateral outer edge of the composite structure layer 22.

[0044] The elastic spandex filaments 2221 in the elastic layer 222 of the present utility model are evenly distributed from the side close to the absorbent core 12 to the lateral outer edge of the flexible side edge 2, making the widths of a number of upper flexible cavities 23 match the width of the flexible side edge 2. The upper surface of the flexible side edge 2 is completely covered by the upper flexible cavities 23, and the inside of the flexible side edge 2 is more three-dimensional due to the elastic restraint of the elastic layer 222, thus better achieving the anti-side leakage effect.

[0045] AsFigure 5 As shown in the figure, as the fourth preferred embodiment of the present utility model, one end of the composite structure layer 22 close to the absorbent core 12 horizontally from top to bottom is successively composed of a first side partition sandwich layer 221, an elastic layer 222, and a second side partition sandwich layer 223, and the other end is successively composed of a first side partition sandwich layer 221 and a second side partition sandwich layer 223 from top to bottom.

[0046] In the elastic layer 222 of the present utility model, the elastic spandex filaments 2221 are distributed from the side close to the absorbent core 12 to the outer edge of the flexible side edge 2 horizontally, but do not extend to be flush with the outer edge of the flexible side edge 2 horizontally, so that the width of the elastic layer 222 is smaller than the width of the flexible side edge 2 and is located at the edge position of one end of the absorbent core 12 horizontally. The outer edge of the flexible side edge 2 is not restricted by the elastic layer 222, and a whole cavity will be formed inside the flexible side edge 2 at this position, which can improve the fluffiness and softness of this position and improve the comfort of the flexible side edge 2.

[0047] As Figure 1 , 2 shown, the horizontal edge of the bottom film 13 extends into the wrapping cavity and forms a second side partition sandwich layer 223, and the second side partition sandwich layer 223 is bonded to the wrapping layer 21.

[0048] The bottom film 13 and the second side partition sandwich layer 223 of the present utility model are integrally formed, and the bonding width between the second side partition sandwich layer 223 and the wrapping layer 21 is about 10 mm, which reduces the number of types of raw materials required for making the light incontinence towel, thereby simplifying the production process of the light incontinence towel, and the flexible side edge 2 is fixedly connected to the bottom film 13 through the second side partition sandwich layer 223 inside, which can increase the firmness and stability of the structure of the flexible side edge 2.

[0049] Furthermore, as Figure 7 , 8 shown, as the fifth preferred embodiment of the present utility model, both horizontal ends of the bottom of the second side partition sandwich layer 223 are bonded to the upper surface of the bottom of the wrapping layer 21 to form a second cavity between the second side partition sandwich layer 223 and the upper surface of the bottom of the wrapping layer 21, and the second side partition sandwich layer 223 and the wrapping layer 21 are adhesively bonded intermittently longitudinally to form a plurality of bottom wrinkles on the lower surface of the bottom of the wrapping layer 21, and the bottom wrinkles divide the second cavity into a plurality of lower flexible cavities 24.

[0050] In the present utility model, after the second partition edge interlayer 223 and the bottom of the wrapping layer 21 are adhesively bonded intermittently along the longitudinal direction, a plurality of lower flexible cavities 24 are uniformly formed in the second cavity. Adhesive points formed by the intermittent bonding of the second partition edge interlayer 223 and the bottom of the wrapping layer 21 are provided on both sides of each lower flexible cavity 24. The adhesive points can support the lower flexible cavity 24 to form a three-dimensional structure, so that the lower flexible cavity 24 maintains structural stability. The inside of the lower flexible cavity 24 can be supported by the inner flexible cavity 224 to further improve the structural stability of the lower flexible cavity 24. The main filling material inside the lower flexible cavity 24 is air, which can improve the softness of the lower surface of the flexible partition edge 2, make the lower surface of the flexible partition edge 2 have a more comfortable touch, and improve the comfort of the light incontinence towel.

[0051] As Figure 1 , 2 shown, as one of the preferred embodiments of the present utility model, the lengths of the wrapping layer 21, the first partition edge interlayer 221, the elastic layer 222, and the second partition edge interlayer 223 are all matched with the length of the flexible partition edge 2. The length of the flexible partition edge 2 is 30%-80% of the longitudinal length of the light incontinence towel.

[0052] The flexible partition edge 2 of the present utility model is mainly composed of an inner flexible cavity 224 formed by a composite structure layer 22, an upper flexible cavity 23 between the first partition edge interlayer 221 and the top of the wrapping layer 21, and a lower flexible cavity 24 between the second partition edge interlayer 223 and the bottom of the wrapping layer 21. The inner flexible cavity 224, the upper flexible cavity 23, and the lower flexible cavity 24 are all cavity bodies filled with air. Due to the existence of these cavity bodies, flexible partition edges 2 with good fluffiness are formed at both transverse ends of the light incontinence towel. The proportion of the length of the flexible partition edge 2 in the light incontinence towel needs to be adjusted according to the length of the light incontinence towel. The proportion of the length of the flexible partition edge 2 is lower in a longer light incontinence towel, while the proportion of the length of the flexible partition edge 2 is higher in a shorter light incontinence towel, that is, to maintain a suitable length for the flexible partition edge 2 to match the leg circumference at the position of the human thigh root, so that the flexible partition edge 2 just fits at the position of the human thigh root.

[0053] As one of the preferred embodiments of the present utility model, the elastic layer 222 is composed of 1-10 elastic spandex filaments 2221, and the fiber denier of the elastic spandex filaments 2221 is 50-700D.

[0054] The elastic spandex filament 2221 of the present utility model is formed by bundling a number of single fine-denier spandex filaments, and finally an elastic spandex filament 2221 with a fiber denier of 50 - 700D is obtained. The fine-denier spandex filament has good softness, hygroscopicity, air permeability, and wrinkle resistance. The elasticity generated by the contraction of the elastic spandex filament 2221 enables the flexible side edge 2 to closely adhere to the position of the human thigh root, which can improve the touch and comfort of the flexible side edge 2. Preferably, more than 3 elastic spandex filaments 2221 are arranged in the elastic layer 222. By using multiple elastic spandex filaments 2221, stress concentration at the flexible side edge 2 can be avoided, and the comfort of the flexible side edge 2 can be improved.

[0055] The present utility model will be further described below through examples and comparative examples.

If there is side leakage, collect and measure the side leakage amount to complete the first test; Rotate the incontinence towel that has completed the first test by 180°, that is, rotate the side of the incontinence towel that was originally at the upper end of the test bench to the lower end of the test bench, and then slowly pour 20 mL of physiological saline onto the center of the surface layer or absorbent cotton surface of the incontinence towel, and observe whether the physiological saline will leak to the outside of the incontinence towel. If there is side leakage, collect and measure the side leakage amount to complete the second test.

[0062] The side leakage test results of the above incontinence towels are shown in Table 1 below:

[0063]

[0064] Table 1

[0065] Conduct a comfort test on the incontinence towel that has completed the above side leakage test: The same tester wears the incontinence towel normally and continuously wears it for 10 minutes, 20 minutes, 30 minutes, and 60 minutes. During the test, the tester switches positions between standing and sitting upright every 5 minutes. After the wearing time is reached, observe whether there are indentations at the tester's thigh root. If there are indentations, observe the obviousness of the indentations.

[0066] The comfort test results of the above incontinence towel are shown in Table 2 below:

[0067]

[0068] Table 2

[0069] From the data in Table 1, it can be seen that the incontinence towels of Example 1 and Comparative Example 1 both have good anti-side leakage effects. The incontinence towel of Example 1 intercepts the liquid that continues to spread horizontally through the flexible partition edge and guides it to spread longitudinally, thereby achieving anti-side leakage. The incontinence towel of Comparative Example 1 absorbs the liquid through the absorbent cotton in the flange and expands to intercept the liquid that continues to spread horizontally to achieve the anti-side leakage effect. Combining the data in Table 2, it can be known that although the flexible partition edge of the incontinence towel of Example 1 for anti-side leakage bulges upward, its interior is mainly filled with air and is fluffy and soft. Therefore, the tester will not leave indentations at the thigh root during the wearing process, and the comfort is good. The incontinence towel of Comparative Example 1 uses absorbent cotton to absorb the liquid and expand to form an anti-side leakage structure. Currently, common absorbent materials such as water-absorbing resin, fluff pulp, and viscose fiber have a certain strength after absorbing the liquid. Therefore, after the tester wears it for a period of time, the thigh root will be squeezed by the anti-side leakage structure to form indentations, and there is no sense of comfort during the wearing process, and the comfort is poor.

[0070] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
