Abstract
Description
Technical Field
[0001] This utility model relates to the field of hygiene products technology, specifically to a three-dimensional water-wicking incontinence towel. Background Technology
[0002] As an important category of incontinence care products, mild incontinence pads play a key role in addressing the daily care needs of people with mild incontinence.
[0003] Mild incontinence refers to the involuntary leakage of small amounts of urine due to various reasons, such as pelvic floor muscle relaxation with age, certain chronic diseases affecting urinary system function, and postpartum changes in women's physical functions. While this condition doesn't significantly impact daily life like severe incontinence, improper management can still cause physical discomfort, psychological stress, and social difficulties. Mild incontinence pads are disposable hygiene products specifically designed for individuals with this type of incontinence. Their main purpose is to absorb and contain these small amounts of urine, keeping the user's skin dry, preventing clothing stains, and thus maintaining personal hygiene and improving quality of life.
[0004] like Figure 1 Currently, most absorbent cores on the market use a hybrid structure similar to a cylinder (or capsule) that encapsulates superabsorbent polymer (SAP) and fluff pulp (PULP) in two layers. This design achieves basic absorption function, is easy to manufacture, and is widely used. However, this design has a single liquid absorption path and cannot adapt to the multidirectional flow requirements of dynamic usage scenarios. Specifically:
[0005] 1. In actual use, the product may not fit properly due to the user's physical activities, resulting in uneven flow and side leakage.
[0006] 2. During use, the core may cause uneven liquid diffusion rates, leading to localized saturation of the product (i.e., low product utilization) and resulting in side leakage.
[0007] 3. The cotton cores of existing light incontinence napkins mainly include capsule shape, rectangle, and improved capsule shape, that is, the straight sides of the capsule shape are changed to arcs, so that the cotton core forms a structure that is wide at both ends and narrow in the middle.
[0008] Capsule-shaped and rectangular cotton cores are more prone to displacement during use. The improved capsule-shaped cores alleviate the displacement issue, but new problems have been discovered. While the front and rear ends of the core have increased in area, the utilization of the rear end of the core is relatively poor, resulting in some waste. Utility Model Content
[0009] This invention provides a three-dimensional water-locking incontinence towel to solve the technical problems in the prior art.
[0010] To solve the above problems, the three-dimensional water-locking incontinence towel provided by this utility model adopts the following technical solution: it includes an absorbent body extending in the front-back direction, a surface layer disposed on the upper surface of the absorbent body that contacts the skin, and a back layer disposed on the lower surface of the absorbent body;
[0011] The absorbent includes a large cotton core and a small cotton core disposed at the front end of the large cotton core, and both the large cotton core and the small cotton core are filled with superabsorbent polymer resin.
[0012] The small cotton core is surrounded by an outer embossed line for connecting the absorbent, the surface layer and the back layer. An inner embossed line is provided inside the outer embossed line. The inner and outer embossed lines are concentric and both are annular. The inner and outer embossed lines compress the absorbent in the thickness direction, forcing the surface layer to squeeze the absorbent, so that a raised barrier ring is formed between the inner and outer embossed lines. The inner side of the barrier ring forms a receiving cavity for storing liquid and reducing liquid leakage.
[0013] The front end of the large cotton core is wider than the rear end, and the left and right sides of the large cotton core are arc-shaped.
[0014] As a further improvement, the inner side of the barrier ring is also provided with embossed strips for compressing the absorbent in the thickness direction. The embossed strips and the inner embossed lines form annular protrusions, increasing the contact area between urine and the absorbent to accelerate urine absorption.
[0015] As a further improvement, the arc angles on the left and right sides of the large cotton core are 105° to 180°.
[0016] As a further improvement, the small cotton core is 10-100mm away from the foremost tip of the large cotton core.
[0017] As a further improvement, the front end of the large cotton core is at least 2 mm wider than the rear end of the large cotton core.
[0018] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0019] 1. This utility model reduces product displacement by changing and improving the shape of the cotton core, while also increasing the utilization rate of the cotton core.
[0020] The cotton core is rounded on both sides, which allows it to fit better against the inner thigh and reduces the shifting of the incontinence pad.
[0021] The front end of the cotton core is wider, forming a "saddle"-like structure. Due to friction during walking, the incontinence pad tends to shift backward. The wider and larger front end of the cotton core can effectively reduce the shift of the incontinence pad.
[0022] Furthermore, the front end of the cotton core has a larger area, while the rear end has a smaller area. This improves the effective utilization rate of the cotton core without changing its total area. The increased front end area also facilitates urine absorption. Since urine is more fluid, when a large volume of urine flows out instantly, it is difficult for it to be completely absorbed immediately, leading to leakage from the front end of the cotton core. This invention reduces the risk of leakage by increasing the front end area of the cotton core.
[0023] 2. By setting inner and outer embossed lines, the present invention forms a raised barrier ring on the upper surface of the absorbent body, making the part of the product that contacts the female private parts concave. The concave part can ensure 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, and is in line with ergonomics.
[0024] An intake cavity is formed inside the barrier ring. The intake cavity can hold urine and reduce the spread of urine to the surrounding area. The urine in the intake cavity permeates to the bottom and is quickly guided to the surrounding absorbent by the blue cotton.
[0025] 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 only lastly permeate into the top of the barrier ring where the density is higher. This ensures that the top of the barrier ring, which is in direct contact with the skin, can remain dry for a long time. Attached Figure Description
[0026] The above and other objects, features, and advantages of the present invention will become readily understood by reading the following detailed description of exemplary embodiments with reference to the accompanying drawings.

[0033] 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.
[0034] The cotton cores of existing incontinence pads (i.e., the large cotton core in this application) are mostly capsule-shaped or rectangular. During use, especially while walking, these pads are prone to shifting. To address this issue, improved versions have emerged, featuring curved sides to better conform to the body and reduce displacement. However, while this improvement reduces displacement, some shifting still occurs. Furthermore, the improved structure, wider at both ends and narrower in the middle, results in less urine flowing to the rear end of the cotton core during actual use, leading to a relatively lower utilization rate despite a larger rear area.
[0035] To address the aforementioned issues, this invention modifies the left and right sides of the large cotton core into an arc shape while widening the front end of the large cotton core, making its width greater than that of its rear end. During walking, friction causes the incontinence pad to tend to shift backward. By widening the front end of the large cotton core, a restraining effect is created, reducing this backward shift and further minimizing the problem. The increased front-end area and relatively smaller rear-end area of the large cotton core improve its utilization rate.
[0036] In addition, by setting a small cotton core at the front end of the large cotton core and forming a raised barrier ring through outer and inner embossed lines, the amount of urine absorbed can be increased by adding a small cotton core. The barrier ring can form a cavity for holding urine, forming a three-dimensional structure and reducing urine side leakage.
[0037] 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.
[0038] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0039] Example 1 of the three-dimensional water-locking incontinence towel provided by this utility model:
[0040] like Figure 2-4As shown, it includes an absorbent body 2 extending in the front-back direction, a surface layer 1 disposed on the upper surface of the absorbent body 2 in contact with the skin, and a back layer 3 disposed on the lower surface of the absorbent body 2.
[0041] The absorbent 2 includes a large cotton core 21 and a small cotton core 22 disposed at the front end of the large cotton core 21. The large cotton core 21 and the small cotton core 22 can be integrally formed or can be composed of two cotton cores. The small cotton core 22 is 10-100mm away from the front end of the large cotton core 21. Both the large cotton core 21 and the small cotton core 22 are filled with superabsorbent polymer (SAP). In this embodiment, in addition to superabsorbent polymer (SAP), fluff pulp (PULP) is also mixed in to improve the urine absorption effect.
[0042] like Figure 3 and Figure 4 As shown, the small cotton core 22 is surrounded by an outer embossed line for connecting the absorbent 2, the surface layer 1, and the back layer 3. In the figure, L1 is the outer embossed line, and an inner embossed line is provided inside the outer embossed line. In the figure, L2 is the inner embossed line. The inner and outer embossed lines are concentrically arranged and are both annular. The inner and outer embossed lines compress the absorbent 2 in the thickness direction, forcing the surface layer 1 to squeeze the absorbent 2, so that a raised barrier ring 4 is formed between the inner and outer embossed lines. The inner side of the barrier ring 4 forms a receiving cavity for storing liquid and reducing liquid leakage.
[0043] Due to the compression of the inner and outer pressure lines, the surface layer 1 presses downwards against the barrier ring 4, making the density of the top of the barrier ring 4 greater than that of the bottom of the barrier ring 4 (i.e., the density of the part above the dotted line L4 in the figure is greater than that of the part below it); when urine permeates, it will preferentially permeate into the fluffy area of the absorbent 2, and the urine will finally permeate into the top of the barrier ring 4 with a higher density. This ensures that the top of the barrier ring 4, which is in direct contact with the skin, can remain dry for a long time.
[0044] The inner side of the barrier ring 4 is also provided with embossed strips for compressing the absorbent 2 in the thickness direction. The embossed strips and the inner embossed lines form annular protrusions, which increase the contact area between urine and absorbent 2 to accelerate urine absorption.
[0045] The front end of the large cotton core 21 is wider than the rear end, and the left and right sides of the large cotton core 21 are arc-shaped, with an arc angle of 105° to 180°. The front end of the large cotton core 21 is at least 2 mm wider than the rear end. In this embodiment, the front end of the large cotton core 21 is 5 mm wider than the rear end.
[0046] While this specification has shown and described numerous embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
