Description

Technical Field

[0001] This utility model relates to the field of hygiene products technology, specifically to a lightly absorbent towel. Background Technology

[0002] With the rapid growth of my country's aging population and the continuous improvement of people's living standards, the market for adult incontinence products is gradually expanding, and the usage scenarios are becoming increasingly segmented. People are gradually realizing that urine is different from menstrual blood. Urine has almost no viscosity, flows out quickly, and needs to be absorbed rapidly and kept dry. Furthermore, menstruation only lasts a few days each month, while incontinence occurs every day, especially for mild incontinence. There is an urgent need for disposable absorbent products that offer better comfort, are quickly absorbed, and keep dry, suitable for people with mild incontinence.

[0003] Currently, most people dealing with mild incontinence use regular sanitary napkins. Since regular sanitary napkins are primarily used during menstruation, they are designed to absorb menstrual blood. However, urine flows much faster than menstrual blood, so using regular sanitary napkins can easily lead to leakage due to insufficient urine absorption. Furthermore, urea in urine decomposes under the action of bacteria, producing ammonia gas, which has an ammonia odor and can significantly impact the daily life and social interactions of people with mild incontinence, even causing psychological stress.

[0004] Currently, mildly absorbent wipes (also known as incontinence wipes) targeting mild incontinence have appeared on the market. These wipes primarily differ from regular sanitary napkins in their absorbent core formula, reducing odor through odor masking or the addition of an antibacterial layer, but their shape and structure are essentially the same as regular sanitary napkins. For example, utility model patent CN220558184U discloses a mild incontinence absorbent wipe that reduces odor by incorporating an antibacterial layer and other structures. Furthermore, this solution features a water-repellent layer that is first folded and bonded before wrapping a surface layer, an antibacterial layer, a drainage layer, and an absorbent sheet. This creates a suspended core structure with a three-dimensional protective barrier on the bottom film layer, eliminating the need for elastic bands and preventing side leakage.

[0005] The aforementioned patent shares a similar concept with existing sanitary napkins, primarily confining liquid within the three-dimensional protective barrier to prevent side leakage. However, due to the greater fluidity of urine, in cases of mild incontinence, even though the urine is confined within the barrier, the highly fluid nature of the urine can easily cause a large area of ​​dampness, as well as discomfort and stuffiness at the contact area due to localized swelling after absorbing urine. Utility Model Content

[0006] This invention provides a lightly absorbent towel to solve the technical problems of lightly absorbent towels having a noticeable damp feeling and causing stuffiness at the contact area in the prior art.

[0007] To solve the above problems, the lightweight absorbent 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.

[0008] The absorber is provided with inner and outer embossed lines for connecting the absorber, the surface layer and the back layer. The inner and outer embossed lines are concentric and are both annular. The inner and outer embossed lines compress the absorber in the thickness direction, forcing the surface layer to squeeze the absorber, 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.

[0009] The surface layer above the barrier ring presses against the barrier ring, making the density at the top of the barrier ring greater than the density at the bottom of the barrier ring, thereby delaying the liquid from penetrating to the top of the barrier ring.

[0010] The inner side of the barrier ring is also provided with embossed strips for compressing the absorber in the thickness direction, and the inner embossed lines and embossed strips form annular protrusions.

[0011] As a further improvement, a flow guiding layer is provided between the surface layer and the absorber.

[0012] As a further improvement, the surface layer is a double-layer hot-air nonwoven fabric.

[0013] As a further improvement, the fiber fineness of the upper layer of the double-layer hot air nonwoven fabric is 1.2-1.5 dtex, and the fiber fineness of the lower layer of the double-layer hot air nonwoven fabric is 2.0-3.0 dtex.

[0014] As a further improvement, the barrier ring is located in the front half of the absorbent body so as to cooperate with the female private parts to absorb urine at a specific point.

[0015] As a further improvement, the protrusion height of the barrier ring is 1-10mm, and the interval between the inner and outer embossed lines is 5-10mm.

[0016] As a further improvement, the barrier ring is a teardrop-shaped inverted triangle.

[0017] As a further improvement, the back layer is a breathable PE film.

[0018] As a further improvement, the bottom of the backing layer is also coated with adhesive to prevent displacement during use.

[0019] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0020] 1. This utility model, by setting inner and outer embossed lines, forms a raised barrier ring on the upper surface of the absorbent body, making the contact area between the product and the female private parts concave, resulting in a better fit. The concave area ensures that the product does not come into close contact with the private parts, effectively reducing the discomfort caused by friction between the product and the private parts when the user moves.

[0021] 2. An accommodating cavity is formed inside the barrier ring. The accommodating cavity can hold urine, reducing the spread of urine to the surrounding area. The urine in the accommodating cavity permeates to the bottom and is quickly guided to the surrounding absorbent by the guide layer.

[0022] 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.

[0023] 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

[0029] 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.

[0030] In existing technologies, lightly absorbent wipes differ from regular sanitary napkins primarily in their absorbent core formula, while their construction remains largely the same. However, urine is more fluid, and when mild incontinence occurs, although the urine is contained within the three-dimensional protective barrier, the highly fluid urine can easily cause a large area of ​​dampness, as well as discomfort and stuffiness at the contact area due to localized swelling after absorbing urine.

[0031] To address the aforementioned issues, this invention incorporates annular inner and outer pressure lines, forming a raised barrier ring between them. In cases of mild incontinence, urine primarily seeps downwards from the inner side of the barrier ring, reducing widespread urine flow. Simultaneously, the raised barrier ring also minimizes contact between the product and the female genitalia, improving breathability and reducing stuffiness.

[0032] 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.

[0033] 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.

[0034] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0035] Example 1 of the lightweight absorbent towel provided by this utility model:

[0036] like Figure 1 and Figure 2 As shown, it includes an absorbent body 6 extending in the front-back direction, a surface layer 5 disposed on the upper surface of the absorbent body 6 in contact with the skin, and a back layer 7 disposed on the lower surface of the absorbent body 6.

[0037] The surface layer 5 is a double-layer hot air nonwoven fabric. Hot air nonwoven fabric is a nonwoven fabric formed by using hot air from a drying equipment to penetrate the fiber web after the fibers are combed, so that they are heated and bonded together. It is fluffy and soft, while having a fast liquid penetration time and low liquid retention rate.

[0038] In addition, the upper layer of the double-layer hot air nonwoven fabric, which is the skin-friendly side, is made of hot air nonwoven fabric with a fiber fineness of 1.2-1.5 dtex, while the lower layer is made of hot air nonwoven fabric with a fiber fineness of 2.0-3.0 dtex, forming a double-layer gradient structure with a dense upper layer and a loose lower layer, which can effectively increase the liquid penetration rate.

[0039] The absorber 6 is provided with an inner embossed line 3 and an outer embossed line 1 for connecting the absorber 6, the surface layer 5 and the back layer 7. The inner embossed line 3 and the outer embossed line 1 are concentrically arranged and are both annular. The inner embossed line 3 and the outer embossed line 1 compress the absorber 6 in the thickness direction, forcing the surface layer 5 to squeeze the absorber 6, so that a raised barrier ring 2 is formed between the inner embossed line 3 and the outer embossed line 1. A receiving cavity for storing liquid and reducing liquid leakage is formed on the inner side of the barrier ring 2.

[0040] The surface layer 5 above the barrier ring 2 compresses the barrier ring 2, making the density at the top of the barrier ring 2 greater than the density at the bottom of the barrier ring 2, thus delaying the liquid from penetrating to the top of the barrier ring 2. Compressed by the inner embossing line 3 and the outer embossing line 1, the surface layer 5 presses downwards on the barrier ring 2, making the density at the top of the barrier ring 2 greater than the density at the bottom of the barrier ring 2 (in this embodiment, the top of the barrier ring 2 refers to...). Figure 2 (The part above the dashed line L1); When urine permeates, it will preferentially permeate into the fluffy area of ​​the absorbent 6, and the urine will finally permeate into the top of the denser barrier ring 2. This ensures that the top of the barrier ring 2, which is in direct contact with the skin, can remain dry for a long time.

[0041] The inner side of the barrier ring 2 is also provided with embossed strips 4 for compressing the absorber 6 in the thickness direction, and annular protrusions are formed between the inner embossed lines 3 and the embossed strips 4. The embossed strips 4 can be a continuous line structure or a dotted structure with several intervals.

[0042] The barrier ring 2 is located in the front half of the absorbent body 6 so as to cooperate with the female private parts to absorb urine at a specific point.

[0043] The height of the protrusion of the barrier ring 2 is 1-10mm, and the interval between the inner embossed line 3 and the outer embossed line 1 is 5-10mm. The protrusion of the barrier ring 2 creates a hollow structure in the middle, which reduces the contact area of ​​the private skin and reduces friction when walking.

[0044] The barrier ring 2 is a teardrop-shaped inverted triangle, ergonomically designed to conform to the human body while allowing liquid to flow precisely downwards. In other embodiments, the barrier ring 2 can also be heart-shaped or elliptical, etc.

[0045] The absorbent body 6 contains superabsorbent polymer (SAP). The absorbent body 6 can be made of fluff pulp combined with SAP, which effectively stores urine without backflow. Urea in urine decomposes under the action of bacteria to produce ammonia, resulting in a distinct ammonia odor. The SAP absorbs the liquid while inhibiting bacterial decomposition, thus suppressing odor production. Mild urinary incontinence leads to a lack of self-confidence in individuals with mild incontinence, affecting their 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 incontinence.

[0046] A flow guiding layer is also provided between the surface layer 5 and the absorber 6. The flow guiding layer is used to guide the liquid and accelerate the flow of the liquid to the rear side of the absorber 6.

[0047] The back layer 7 is a breathable PE film, and the bottom of the back layer 7 is also coated with adhesive to prevent displacement during use.

[0048] The perimeter embossing and protective wings of the lightly absorbent towel are existing structures and will not be described in detail here.

[0049] 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.
