TECHNICAL FIELD
[0001] The utility model relates to sanitary article technical field, concretely relates to a sanitary article double cotton core liquid absorption structure and light incontinence towel. BACKGROUND
[0002] Light incontinence is more common in the elderly and postpartum women, and in some cases of increased intra-abdominal pressure, urine is uncontrollably discharged from the urethra, causing odor, dampness, and thus affecting normal life. Light incontinence towel is a disposable absorbent sanitary article for light incontinence groups. The core is usually composed of wood pulp and high-absorbent polymers for urine. When used, it is placed on the underpants like a sanitary napkin. Light incontinence towel is light, portable, and does not feel heavy like adult diapers. It 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 napkins in the formula of the absorbent core. Its structure is similar to that of ordinary sanitary napkins. However, urine is different from menstrual blood. Urine has almost no viscosity and is more fluid. When there is a sudden large amount of urine discharge, the urine penetrates downward to the absorbent body. However, due to the large amount of urine, after the front side of the light incontinence towel absorbs a large amount of urine, the absorbent body is in a relatively saturated state, and the urine absorption effect and absorption speed decrease. It is difficult for urine to quickly penetrate to the back side of the absorbent body in a short time, and the remaining urine cannot penetrate to the absorbent body in time, resulting in a feeling of dampness and heat. In addition, due to the greater fluidity of urine, urine leakage may also occur. SUMMARY
[0004] The utility model provides a sanitary article double cotton core liquid absorption structure and light incontinence towel to solve the technical problem of the feeling of dampness and heat and urine leakage in the prior art due to the relatively slow urine absorption speed.
[0005] To solve the above problems, the sanitary article double cotton core liquid absorption structure provided by the utility model adopts the following technical scheme: an absorbent body extending in the front-rear direction, a surface layer arranged on the upper surface of the absorbent body and contacting the skin, and a back layer arranged on the lower surface of the absorbent body.
[0006] The absorbent body includes a cotton core, an upper cladding layer arranged on the upper surface of the cotton core, and a lower cladding layer arranged on the lower surface of the cotton core.
[0007] The cotton core includes a large cotton core and a small cotton core arranged below the large cotton core. The area of the small cotton core is smaller than that of the large cotton core. The outer side of the small cotton core is provided with a ring-shaped embossed line surrounding the small cotton core. The small cotton core and the embossed line are arranged at intervals. The embossed line compresses the absorbent body in the thickness direction, so that a triangular area for temporarily storing and diffusing urine is formed between the side surface of the small cotton core, the bottom surface of the large cotton core, and the upper surface of the lower cladding layer.
[0008] As a further improvement, the small cotton core has a cross section in the shape of an isosceles trapezoid.
[0009] As a further improvement, the small cotton core has a top width greater than a bottom width.
[0010] As a further improvement, the outer embossed line is further provided with an inner embossed line, the inner embossed line and the outer embossed line are concentrically arranged and are both annular, the inner embossed line and the outer embossed line compress the absorbent in the thickness direction, forcing the surface layer to extrude the absorbent, forming a raised barrier ring between the inner embossed line and the outer embossed line, and forming a containing cavity inside the barrier ring for storing liquid and reducing liquid leakage.
[0011] As a further improvement, a drainage layer is arranged between the absorbent and the surface layer for guiding the liquid to accelerate the diffusion and absorption of the liquid.
[0012] As a further improvement, the drainage layer is blue cotton, the blue cotton is arranged inside the barrier ring and extends outwardly between the inner embossed line and the outer embossed line, the inner embossed line compresses the absorbent in the thickness direction to make the edge of the blue cotton curl up, so that the edge of the blue cotton is not tightly attached to the absorbent.
[0013] As a further improvement, the shape of the blue cotton is the same as the profile of the inner embossed line or the profile of the outer embossed line.
[0014] The utility model discloses still disclose a light incontinence pad, the light incontinence pad has the sanitary product double cotton core liquid absorption structure of above.
[0015] The beneficial effects of the above technical scheme of the utility model are as follows:
[0016] 1. The utility model discloses a double-layer cotton core, the area of the small cotton core is less than that of the large cotton core, the outer embossed line compresses the thickness of the absorbent, and the triangular area for temporarily storing urine and diffusing urine is formed between the side surface of the small cotton core, the bottom surface of the large cotton core and the upper surface of the lower cover layer.
[0017] The triangular area has strong support and is not easy to deform under the extrusion of the user.
[0018] When the instantaneous urine flow is too large, the urine is absorbed by the absorbent and penetrates downward along the absorbent, the absorbent is difficult to quickly absorb all the urine due to the urine concentrated on the front side of the light incontinence pad, and part of the urine will flow to the triangular area. Since the triangular area has a hollow structure, the hollow structure can increase the conduction and flow of the urine and help absorption. After the urine flows to the triangular area, the urine will flow and diffuse around, and then be absorbed by the absorbent, thereby accelerating the absorption of the urine.
[0019] 2. By setting inner and outer embossed lines, this utility model 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.
[0020] 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.
[0021] 3. The inner pressure lines act on the blue cotton, causing the edges of the blue cotton to curl up and not fit tightly with the main body of the product. This raised area can isolate the female private parts from the incontinence napkin to a certain extent during use, keeping the female private parts dry. Attached Figure Description
[0022] 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. In the drawings, several embodiments of the present invention are shown by way of example and not limitation, and like or corresponding reference numerals denote like or corresponding parts, wherein:

[0028] 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.
[0029] In existing technology, the structure of incontinence pads is similar to that of ordinary sanitary napkins. However, urine differs from menstrual blood; urine has almost no viscosity and is much more fluid. When a large amount of urine flows out at once, it seeps downwards into the absorbent core. However, due to the large volume of urine, the front of the incontinence pad absorbs a significant amount, leaving the absorbent core relatively saturated. This reduces the absorption efficiency and speed, making it difficult for urine to quickly seep into the back of the absorbent core. The remaining urine cannot penetrate the absorbent core in time, leading to a damp and stuffy feeling. Furthermore, due to the greater fluidity of urine, leakage may occur at the front.
[0030] To address the aforementioned issues, this invention employs a double-core structure, where a smaller core is placed below the traditional large core. The outline of the smaller core is identical to that of the barrier ring, but smaller than the outline of the outer embossing lines. When the outer embossing lines connect the upper covering layer, the large core, the smaller core, and the lower covering layer, they compress the absorbent's thickness, creating a triangular area between the side of the smaller core, the bottom of the large core, and the upper surface of the lower covering layer. This area serves to temporarily store and diffuse urine.
[0031] The hollowed-out triangular area increases the conductivity and fluidity of urine, accelerating its flow to the absorbent body and its gradual absorption. This allows sufficient space for urine to continue to penetrate downwards, accelerating absorption and reducing the feeling of dampness and premature leakage.
[0032] 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.
[0033] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0034] Example 1 of the double-cotton-core liquid absorption structure for sanitary products provided by this utility model:
[0035] like Figure 1 and Figure 2 As shown, it includes an absorbent body 6 extending in the front-to-back direction, a surface layer disposed on the upper surface of the absorbent body 6 that contacts the skin, and a back layer disposed on the lower surface of the absorbent body 6. Both the surface layer and the back layer are non-woven fabric products, and are not shown in the figure.
[0036] The absorbent core 6 includes a cotton core, an upper covering layer 5 disposed on the upper surface of the cotton core, and a lower covering layer 4 disposed on the lower surface of the cotton core. The cotton core is filled with superabsorbent polymer (SAP), which increases liquid absorption capacity and inhibits bacterial growth, reducing odor. In this embodiment, both the upper covering layer 5 and the lower covering layer 4 are toilet paper.
[0037] The above are all existing technologies, and their specific structures will not be described in detail here.
[0038] like Figure 1 As shown, the absorbent core includes a large absorbent core 1 and a small absorbent core 3 located below the large absorbent core 1. The large absorbent core 1 and the small absorbent core 3 can be integrally formed or cut separately and then combined to form the absorbent core. The area of the small absorbent core 3 is smaller than that of the large absorbent core 1. The outer side of each small absorbent core 3 is provided with an outer embossed line, which is spaced apart from the small absorbent core 3. The distance between the small absorbent core 3 and the outer embossed line is 2-15mm. The outer embossed line compresses the absorbent body 6 in the thickness direction, forming a triangular area 2 between the side of the small absorbent core 3, the bottom surface of the large absorbent core 1, and the upper surface of the lower covering layer 4. This triangular area 2 serves as a transition zone. The triangular structure has strong support and is not easily deformed under compression, reducing the deformation of the triangular area 2 due to compression, which would affect the conductivity and fluidity of the urine.
[0039] While compressing the absorbent body 6 to form the triangular area 2, the outer embossed lines can also fix the small cotton core. The inner embossed lines further fix the triangular area 2. Together, they can fix the small cotton core 3 and increase the stability of the triangular area 2.
[0040] In this embodiment, the cross-section of the small cotton core 3 is an isosceles trapezoid, and the top width of the small cotton core 3 is greater than the bottom width.
[0041] Through the aforementioned triangular area 2 structure, combined with the conductive layer above the absorbent body 6 (the conductive layer is existing technology, which is generally set above the absorbent body 6 to guide urine to other positions of the absorbent body 6), the absorption speed of urine is improved, the feeling of dampness and the situation of urine leakage are reduced, and the odor caused by urine leakage is reduced.
[0042] This invention significantly reduces pre-leakage of urine and minimizes the production of odors such as ammonia by adding superabsorbent polymer and incorporating a triangular zone 2 structure. 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.
[0043] Example 2 of the double-cotton-core liquid absorption structure for sanitary products provided by this utility model:
[0044] The main difference between this embodiment and Embodiment 1 is that:
[0045] In this embodiment, the absorber 6 is provided with inner and outer embossed lines for connecting the absorber 6, the surface layer and the back layer. 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 6 in the thickness direction, forcing the surface layer to squeeze the absorber 6, so that a raised barrier ring 7 is formed between the inner and outer embossed lines. A receiving cavity for storing liquid and reducing liquid leakage is formed on the inner side of the barrier ring 7.
[0046] A flow-guiding layer is provided between the absorbent 6 and the surface layer to accelerate liquid diffusion and absorption. In this embodiment, the flow-guiding layer is blue cotton 8. The blue cotton 8 fiber has a lower denier, meaning the blue cotton 8 fibers are finer and have a relatively better water absorption effect. After the urine flows to the blue cotton 8, the blue cotton 8 quickly conducts the urine downwards.
[0047] The blue cotton pad 8 is positioned inside the barrier ring 7 and extends outward between the inner and outer embossed lines. The shape of the blue cotton pad 8 is the same as the outline of either the inner or outer embossed line. The inner embossed line compresses the absorbent body 6 in the thickness direction, causing the edges of the blue cotton pad 8 to curl up, thus preventing the edges of the blue cotton pad 8 from tightly adhering to the absorbent body 6. This raised area provides a degree of isolation between the woman's private parts and the incontinence pad during use, keeping the area dry. When the woman moves around, this raised area facilitates airflow, further reducing the feeling of dampness.
[0048] In addition, the space can temporarily store a small amount of urine, which is then absorbed by the cotton core, thus playing a certain transitional role.
[0049] Embodiment 3 of the incontinence towel provided by this utility model:
[0050] like Figure 3 As shown, in this embodiment, the light incontinence towel has the dual cotton core liquid absorption structure of the sanitary products of Embodiments 1 and 2.
[0051] 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.
