Description

Technical Field

[0001] This utility model relates to the field of disposable hygiene products, and more particularly to a core with an odor-removing capsule, diapers, and pull-up pants. Background Technology

[0002] Babies or adults wearing disposable hygiene products are prone to developing an odor when defecating or urinating. Some existing disposable hygiene products use a thin deodorizing layer, which is insufficient to deodorize large areas of liquid, resulting in poor odor removal.

[0003] Chinese Patent Application No. 202022417028.9 discloses an antibacterial and deodorizing diaper, comprising a diaper, a back waistband, a front waistband, and a moisture-absorbing core. The moisture-absorbing core is located in the middle of the diaper, with the front waistband at the front end and the back waistband at the rear end. An elastic waistband is located in the upper middle part of the front waistband. An antibacterial and deodorizing layer is located in the middle of the upper surface of the moisture-absorbing core, and leak-proof edges are provided on both sides of the moisture-absorbing core. This antibacterial and deodorizing diaper uses only one layer of antibacterial and deodorizing material, making it difficult to deodorize large areas of liquid, resulting in poor deodorization. Utility Model Content

[0004] Therefore, to address the aforementioned problems, this invention proposes a core with an odor-absorbing capsule, a diaper, and a pull-up diaper. This solves the technical problem of poor odor-absorbing effect of the core.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A core with an odor-removing capsule includes a core body, the core body including an absorbent core and a coating layer covering the absorbent core, the top of the absorbent core having a plurality of first odor-removing particles, the first odor-removing particles including a water-soluble film and an odor-removing agent coated within the water-soluble film, and the absorbent core having a plurality of second odor-removing particles, the second odor-removing particles having the same structure as the first odor-removing particles.

[0007] Further:

[0008] The top of the absorbent core is provided with a urine tank and a feces tank, and a plurality of the first deodorizing particles are provided in the urine tank and the feces tank.

[0009] The urine tank is provided with multiple guide channels arranged along its length.

[0010] The cross-sections of multiple guide channels are wavy.

[0011] The circumference of the waste tank is provided with at least one annular groove, and the first deodorizing particle is fixed in the inner ring of the annular groove.

[0012] The diameter of the second deodorizing particle is less than 2 mm.

[0013] The number of the second deodorizing particles gradually decreases from top to bottom.

[0014] The deodorizing agent is in powder form.

[0015] This utility model also provides a diaper based on the above-mentioned core with odor-removing capsule, including a first liquid-permeable top layer, a core body, and a first liquid-impermeable bottom layer arranged from top to bottom.

[0016] This utility model also provides pull-up pants based on the above-mentioned core with deodorizing capsule, including two elastic waistbands and a core body connected to the two elastic waistbands. The top of the core body is provided with a second liquid-permeable top layer and the bottom of the core body is provided with a second liquid-impermeable bottom layer.

[0017] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0018] The deodorizing agent in the first deodorizing granules of this invention is not easily lost or deteriorated under the coating of a water-soluble film. Urine and feces can come into contact with the first deodorizing granules. The water-soluble film dissolves in water, allowing the deodorizing agent to remove odors, thus improving the deodorizing effect. Some liquid enters the absorbent core, where the second deodorizing granules can deodorize the interior of the absorbent core. When undissolved, the second deodorizing granules are granular and will not settle at the bottom of the absorbent core layer, allowing them to be distributed in various positions within the absorbent core. Simultaneously, the deodorizing agent can flow with the liquid, deodorizing various positions within the absorbent core and improving the deodorizing effect. Furthermore, the top of the absorbent core is equipped with a urine tank and a feces tank. These tanks not only separate urine and feces but also store a large number of the first deodorizing granules in the urine. In the liquid and fecal tanks, large amounts of urine and fecal matter first enter, allowing the first deodorizing particles to fully contact the urine and fecal matter immediately, improving the deodorization effect. Furthermore, the guide channel has a guiding effect, preventing urine leakage. Additionally, the annular groove has a flow-blocking function, preventing fecal matter from flowing out and preventing large amounts of fecal matter and urine from mixing and producing odor, while also effectively deodorizing the fecal matter. Furthermore, the second deodorizing particles have a diameter of less than 2mm, preventing their large mass from settling at the bottom of the absorbent core during production. Finally, because a large amount of liquid is absorbed at the top, the number of second deodorizing particles gradually decreases from top to bottom, saving raw materials and improving the utilization rate of the second deodorizing particles.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Example 1

[0027] refer to Figure 1 and Figure 2 Example 1 provides a core with a deodorizing capsule, including a core body 1. The core body 1 includes an absorbent core 11 and a coating layer 12 covering the absorbent core 11. The top of the absorbent core 11 is provided with a plurality of first deodorizing particles 13. The first deodorizing particles 13 include a water-soluble film 131 and a deodorizing agent 132 coated within the water-soluble film 131. The absorbent core 11 is provided with a plurality of second deodorizing particles 14. The second deodorizing particles 14 have the same structure as the first deodorizing particles 13.

[0028] The diameter of the second deodorizing particle 14 is usually set to be less than 2 mm. During production, to prevent the second deodorizing particle 14 from being too large and settling at the bottom of the absorption core 11, it can also be set to be greater than or equal to 2 mm, depending on the specific situation.

[0029] The number of the second deodorizing particles 14 mentioned above is usually set to gradually decrease from top to bottom, or it can be evenly distributed or distributed in other structures, depending on the specific situation.

[0030] The aforementioned water-soluble film 131 is PVA or other films that can dissolve in water, which are well-known materials and will not be described in detail here.

[0031] The deodorizer 132 mentioned above is a powder and is a well-known material, so it will not be described in detail here.

[0032] refer to Figure 3 The present invention also provides a diaper based on the above-mentioned core with deodorizing capsule, comprising a first liquid-permeable top layer 21, a core body 1, and a first liquid-impermeable bottom layer 22 arranged from top to bottom.

The top of the core body 1 is provided with a second liquid-permeable top layer 32 and the bottom of the core body 1 is provided with a second liquid-impermeable bottom layer 33.

[0034] The working principle of Example 1 is as follows:

[0035] When diapers or pull-ups are worn on the body, urine or feces enter the absorbent core 11. The urine or feces can come into contact with the first deodorizing particles 13. The water-soluble film 131 dissolves in water, and the liquid can move the deodorizing agent 132. The deodorizing agent 132 can deodorize the top of the absorbent core 11. Some liquid enters the absorbent core 11, and the second deodorizing particles 14 can deodorize the inside of the absorbent core 11. The first deodorizing particles 13 and the second deodorizing particles 14 can deodorize all parts of the absorbent core 11, improving the deodorizing effect. Example 2

[0036] refer to Figures 1 to 5 The main difference between Embodiment 2 and Embodiment 1 is that the top of the absorbent core 11 in Embodiment 2 is provided with a urine tank 15 and a feces tank 16, and multiple first deodorizing particles 13 are provided in the urine tank 15 and the feces tank 16. Multiple guide channels 151 are provided on the urine tank 15 along its length. The cross-section of the multiple guide channels 151 is wavy. The periphery of the feces tank 16 is provided with an annular groove 161, and the first deodorizing particles 13 are fixed within the annular groove 161.

[0037] The aforementioned first deodorizing particle 13 can be fixed in the annular groove 161 by glue or other means, depending on the specific situation.

[0038] The aforementioned guide channel 151 may be omitted, depending on the specific circumstances.

[0039] The aforementioned annular groove 161 may be omitted, depending on the specific circumstances.

[0040] The first deodorizing particle 13 and the second deodorizing particle 14 mentioned above can also be the antibacterial and deodorizing spherical microparticles provided by Chinese Patent Application No. 202110300109.7, entitled "An Antibacterial and Deodorizing Spherical Microparticles and Their Preparation Process". Alternatively, the deodorizing granules provided by Chinese Patent Application No. 202210048923.9 can also be other deodorizing and harmless particles. Typically, water-soluble particles are used, or particles that turn into powder when subjected to greater pressure can be used, depending on the specific circumstances.

[0041] In Embodiment 2, the top of the absorbent core 11 is provided with a urine tank 15 and a feces tank 16. The urine tank 15 and the feces tank 16 can not only separate urine and feces, but also store a large number of first deodorizing particles 13 in the urine tank 15 and the feces tank 16. A large amount of urine and feces will enter the urine tank 15 and the feces tank 16 first, and the first deodorizing particles 13 can fully contact the urine and feces at the first time, thereby improving the deodorizing effect.

[0042] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
