Description

Technical Field

[0001] The utility model relates to the technical field of adult diapers, in particular to an adult diaper with an S-cut closure system and a deodorizing effect. Background Art

[0002] Adult diapers are absorbent materials primarily made of fluff pulp and polymer absorbents, designed to absorb urine. As essential daily necessities for nursing homes and bedridden elderly, existing adult diapers typically replicate the design of baby diapers, scaling them up. Their design primarily focuses on the fluff pulp and polymer absorbents, with few other design elements considered. Consequently, they lack adequate consideration for deodorizing properties. Therefore, we aim to improve this by developing an adult diaper with a deodorizing function to avoid awkward use. Utility Model Content

[0005] The deodorizing absorbent core comprises a fluff pulp layer and a polymer deodorizing layer; the deodorizing absorbent core is cut to form a plurality of cutting grooves; the plurality of cutting grooves are spaced apart along the longitudinal direction and / or the width direction of the deodorizing absorbent core;

[0006] The front side of the base film is provided with a front waist tape, and the two ends of the back side are provided with back waist tapes; the back waist tape can be adhered to the front waist tape; the front waist tape and / or the back waist tape are provided with magic hooks.

[0007] Optionally, the polymer deodorizing layer is resin particles formed by polymerizing hydrophilic monomers having unsaturated double bonds.

[0008] Optionally, the hydrophilic monomer is selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, fumaric acid, 2-propyleneamine-2-methylpropanesulfonic acid, maleic acid, maleic anhydride, fumaric acid and fumaric anhydride.

[0009] Optionally, the cutting groove is divided into a long strip-shaped fracture groove and a hole-shaped countersunk groove; the fracture groove extends along the longitudinal direction of the deodorizing absorption core and is evenly spaced in the middle of the deodorizing absorption core; the countersunk groove is arranged on both sides of the width of the deodorizing absorption core, and is located on opposite sides of the fracture groove.

[0010] Optionally, three-dimensional side guards are provided on both sides of the width of the adult diaper.

[0011] Optionally, the deodorizing absorption core further includes absorbent paper, and the absorbent paper is coated on the outer sides of the fluff pulp layer and the polymer deodorizing layer.

[0029] The deodorant absorption core 20 includes a fluff pulp layer 22 and a polymer deodorant layer 23; the deodorant absorption core 20 is formed with a plurality of cutting grooves 40 by cutting; the plurality of cutting grooves 40 are arranged at intervals along the longitudinal direction and / or the width direction of the deodorant absorption core 20;

[0030] A front waist sticker 31 is provided on the front side of the bottom film 30, and rear waist stickers 32 are provided at both ends of the rear side; the rear waist sticker 32 can be adhered to the front waist sticker 31; a magic hook 33 is provided at the front waist sticker 31 and / or the rear waist sticker 32.

[0031] In the present utility model, the deodorant absorption core 20 includes a fluff pulp layer 22 and a polymer deodorant layer 23. The fluff pulp can improve the softness and skin-friendliness of the diaper, and the polymer deodorant layer 23 can reduce the urine odor, effectively avoiding embarrassing phenomena during use. A plurality of cutting grooves 40 are formed by a cutting and drilling process. The cutting grooves 40 expand the surface area of the deodorant absorption core 20, can increase the effective contact area between the liquid and the deodorant absorption core 20, enable urine and loose stools to be absorbed and diffused into the interior of the deodorant absorption core 20 more quickly, keep the surface of the diaper product dry and comfortable, and also facilitate the use of a large-volume deodorant absorption core 20 to store liquid and avoid urine leakage. Moreover, through the magic hook 33 at the front waist sticker 31 or the rear waist sticker 32, the front waist sticker 31 and the rear waist sticker 32 can be joined and pasted together to form a closed diaper system without using glue, which is convenient and comfortable for the user to wear and can be conveniently and repeatedly pasted to adjust the wearing position.

[0032] The magic hook 33 does not require the use of glue and can be repeatedly pasted to adjust the wearing position, which is convenient and comfortable for the user to wear. The magic hook 33 can use the magic hook 33 products of the existing technology, and will not be described in detail here.

[0033] Superabsorbent resins are widely used as water retention agents in agriculture or horticulture, anti-dew condensation agents in building materials, materials for removing water in petroleum, or outer waterproof coatings in cable wires, as well as sanitary products such as diapers, feminine hygiene products, disposable wipes, etc., especially in the largest volume for use on diapers.

[0034] In this embodiment, the applicant selectively uses a superabsorbent resin with antibacterial and deodorant capabilities. Specifically, the polymer deodorant layer 23 is resin particles polymerized from hydrophilic monomers having unsaturated double bonds. For details of this polymer deodorant material, see the superabsorbent resin material disclosed in the patent number CN201710260703.1 for the composition.

[0035] Preferably, the hydrophilic monomer is selected from the following groups: acrylic acid, methacrylic acid, maleic acid, fumaric acid, 2-acrylamido-2-methylpropanesulfonic acid, maleic acid, maleic anhydride, fumaric acid, and fumaric anhydride.

[0036] In this embodiment, please refer to Figure 2 , the cutting slot 40 is divided into a long strip-shaped fracture slot 41 and a hole-shaped counterbore slot 42; the fracture slot 41 extends along the longitudinal direction of the deodorant absorption core 20 and is evenly spaced in the middle of the deodorant absorption core 20; the counterbore slot 42 is arranged on both sides of the width of the deodorant absorption core 20 and is located on the opposite sides of the fracture slot 41. The fracture slot 41 extends along the longitudinal direction of the deodorant absorption core 20, which can facilitate the lateral symmetrical deformation of the left and right sides of the deodorant absorption core 20 and the bending deformation along the longitudinal direction; the counterbore slot 42 is convenient for drilling and forming, and at the same time can effectively expand the surface area of the deodorant absorption core 20, thereby increasing the effective contact area between the liquid and the deodorant absorption core 20, enabling urine and loose stools to be absorbed and diffused more quickly into the interior of the deodorant absorption core 20.

[0037] In this embodiment, three-dimensional side guards 50 are provided on both sides of the width of the adult diaper. The three-dimensional side guards 50 have water repellency and can effectively prevent urine from leaking out from both sides of the adult diaper.

[0038] In this embodiment, the deodorant absorption core 20 further includes a water-absorbing paper 21, and the water-absorbing paper 21 covers the outside of the fluff pulp layer 22 and the polymer deodorant layer 23. The water-absorbing paper 21 is made of superabsorbent resin, and the superabsorbent resin (SAP) is made mainly of starch and acrylate and has outstanding water absorption and water storage performance.

[0039] In some embodiments, two layers of water-absorbing paper 21 are provided, and the fluff pulp layer 22 and the polymer deodorant layer 23 are covered between the two layers of water-absorbing paper 21.

[0040] In this embodiment, please refer to Figure 3 , one layer of water-absorbing paper 21 is provided, and one layer of water-absorbing paper 21 is wound around and covers the outside of the fluff pulp layer 22 and the polymer deodorant layer 23.

[0041] In this embodiment, the surface film 10 is a hot air non-woven fabric and / or a spunbond non-woven fabric, and the bottom film 30 is a PE breathable film. The hot air non-woven fabric and the spunbond non-woven fabric have better skin-friendly performance, and while the PE breathable film has better load-bearing deformation ability, it can maintain breathability.

[0042] Certainly, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations and substitutions are all included within the scope defined by the claims of this application.
