Description

Technical Field

[0001] The utility model relates to the field of diaper products, in particular to an antibacterial diaper. Background Art

[0002] For existing hygiene products, in order to avoid generating peculiar smells after liquid absorption, antibacterial agents are usually added to the liquid-absorbing materials of the core. This technology is shown in Chinese Patent Application CN 118076328 A, an absorbent article, which includes a liquid-permeable front sheet disposed on the skin-facing side, a back sheet disposed on the non-skin-facing side, and an absorbent body between the front sheet and the back sheet. The absorbent body has an absorbent sheet containing a fibrous material as a component. The absorbent article has a longitudinal direction corresponding to the front-back direction of the wearer and a lateral direction orthogonal to the longitudinal direction. In the absorbent article, the absorbent body has a laminated structure at least in the central portion in the lateral direction of the absorbent body. The laminated structure includes a front-side absorbent sheet located on the skin-facing side, a back-side absorbent sheet located on the non-skin-facing side, and a central absorbent portion located between the front-side absorbent sheet and the back-side absorbent sheet. A water-soluble antibacterial agent, a porous material, and a polyphenol compound are contained in the central absorbent portion.

[0003] However, under this product structure, although a large amount of body fluid is absorbed by the central absorbent portion, the front-side absorbent sheet that comes into contact with the body fluid for the first time still inevitably has peculiar smells, affecting the use comfort. Summary of the Utility Model

[0004] Therefore, the utility model provides an antibacterial diaper, which solves the problem that the antibacterial effect of diaper products is insufficient and peculiar smells are easily generated.

[0005] To achieve the above object, the utility model is realized by the following technical solutions:

[0006] An antibacterial diaper, comprising a liquid-permeable surface layer, an absorbent body and a liquid-impermeable bottom layer which are arranged in a stacked manner. The diaper is defined with a longitudinal direction in the length direction and a transverse direction in the width direction. The transverse two-side edges of the liquid-permeable surface layer are located inside the absorbent body. Leakage-preventing side edges are arranged on the transverse two-side edges of the absorbent body. The longitudinal two ends and one transverse outer end of the leakage-preventing side edges are bonded to the liquid-impermeable bottom layer. A diversion part is arranged symmetrically along the longitudinal center between the liquid-permeable surface layer and the liquid-impermeable bottom layer. A gap is formed between the two diversion parts to form a main absorption groove hollowed out between the liquid-permeable surface layer and the absorbent body. An antibacterial agent layer is sprayed and applied on the surface of the liquid-permeable surface layer close to the absorbent body. Each of the two diversion parts includes a first non-woven fabric layer close to the longitudinal symmetry center of the diaper and a second non-woven fabric layer connected to the lower surface of the first non-woven fabric layer. The free end of the second non-woven fabric layer extends horizontally outwards and is bonded to the leakage-preventing side edge, so that the second non-woven fabric layer warps up with the erection of the leakage-preventing side edge.

[0007] Preferably, a plurality of diversion pressure grooves extending in the transverse direction are arranged on the surface of the second non-woven fabric layer.

[0008] Preferably, a plurality of infiltration holes are formed in the first non-woven fabric layer.

[0009] Preferably, both the first non-woven fabric layer and the second non-woven fabric layer are hydrophilic non-woven fabrics.

[0010] Preferably, the first non-woven fabric layer is a hydrophilic non-woven fabric and the second non-woven fabric layer is a water-repellent non-woven fabric.

[0011] Preferably, the transverse width of the main absorption groove is 10-50 millimeters.

[0012] Preferably, the antibacterial agent layer is formed by spraying benzalkonium chloride or quaternary ammonium salt.

[0013] By adopting the foregoing technical solution, the beneficial effects of the utility model are as follows:

[0014] This technical solution shortens the transverse width of the liquid-permeable surface layer and improves the form of the traditional diversion layer. During the use of the diaper product, the second non-woven fabric layer in the diversion part can warp up with the leakage-preventing side edge, forming a current-limiting structure composed of the diversion part and the leakage-preventing side edge inside the diaper product. Thus, body fluids are restricted within the diversion layer and the leakage-preventing side edge. A main absorption groove is formed between the two symmetrical diversion parts to absorb liquid in the first time. At the same time, an antibacterial agent layer is also arranged inside the liquid-permeable surface layer. After body fluids enter the inside of the diaper through the liquid-permeable surface layer, the antibacterial effect of the liquid-permeable surface layer can be realized on the premise of sufficient diversion and absorption, ensuring no peculiar smell for a long time and protecting the skin on the side in contact with the human body, avoiding the influence of the existing antibacterial agent components on the human skin, and fully ensuring the comfort during use.

Detailed implementation manners

[0018] The following will combine specific embodiments to detail the implementation manners of the present utility model, so as to fully understand how the present utility model uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.

[0019] Reference Figure 1 and Figure 2 , an antibacterial disposable diaper, comprising a liquid-permeable surface layer 1, an absorbent body 2 and a liquid-impermeable bottom layer 3 which are laminated. The disposable diaper is defined to have a longitudinal direction in the length direction and a transverse direction in the width direction. The transverse two side edges of the liquid-permeable surface layer 1 are located inside the absorbent body 2. The transverse two side edges of the absorbent body 2 are provided with leak-proof edges 31. The longitudinal two ends and the transverse outer end of the leak-proof edges 31 are bonded to the liquid-impermeable bottom layer 3. Among them, the leak-proof edges 31 are made of a water-repellent material folded and internally provided with multiple elastic cords in the length direction. This is a conventional component of the disposable diaper product. At the same time, the basic components such as the waistband and leg elastic cords of the disposable diaper are not shown in this embodiment, which are not the improvement points of this technical solution and will not be elaborated here;

[0020] In this embodiment, a diversion part is symmetrically arranged along the longitudinal center between the liquid-permeable surface layer 1 and the liquid-impermeable bottom layer 3. A gap is formed between the two diversion parts to form a main absorption groove 6 that is hollow between the liquid-permeable surface layer 1 and the absorbent body 2. Specifically, the main absorption groove 6 needs to have a certain size, and its transverse width can be any value between 10 and 50 millimeters according to different product models and design purposes, so as to expose enough surface of the absorbent body 2 to ensure a sufficient absorption rate;

[0021] Among them, an antibacterial agent layer 11 is sprayed and applied on the surface of the liquid-permeable surface layer 1 close to the absorbent body 2. Among them, the antibacterial agent layer 11 is formed by spraying benzalkonium chloride or quaternary ammonium salt to form an antibacterial and deodorizing effect on the surface close to the absorbent body 2; this process is pre-treated before the application of the liquid-permeable surface layer 1 material, and can be carried out by spraying or roll coating;

[0022] In this embodiment, both of the two diversion parts each include a first non-woven fabric layer 4 close to the longitudinal symmetry center of the diaper, and a second non-woven fabric layer 5 connected to the lower surface of the first non-woven fabric layer 4. The free end of the second non-woven fabric layer 5 extends transversely outwards and is bonded to the leak-proof side edge 31, so that the second non-woven fabric layer 5 tilts up as the leak-proof side edge 31 stands up. Among them, the first non-woven fabric layer 4 is a hydrophilic non-woven fabric, and a plurality of downward seepage holes are formed in the first non-woven fabric layer 4. The downward seepage holes are through holes arranged in an array in a dense manner to further increase the downward seepage rate. With such a structure, the first non-woven fabric layer 4 on both sides of the main absorption groove 6 can also achieve an absorption effect, which is equivalent to increasing the width of the main absorption groove 6. Correspondingly, the second non-woven fabric layer 5 is a water-repellent non-woven fabric, which can form a shape of absorbing liquid and then flowing back: that is, after a large amount of liquid enters the inside of the diaper, one side of the transverse end of the second non-woven fabric layer 5 tilts up as the leak-proof side edge 31 stands up, forming another anti-side leakage structure inside the diaper product to avoid side leakage, and the unabsorbed body fluid then conducts towards the center and is absorbed by flowing back.

[0023] And on this basis, the second non-woven fabric layer 5 can also be designed as a hydrophilic non-woven fabric, which can achieve the above effects and also realize downward seepage absorption during the conduction process, with a higher absorption rate, but it has a certain reduction in the leak-proof effect.

[0024] In this technical solution, by shortening the transverse width of the liquid-permeable surface layer 1 and improving the form of the traditional diversion layer, during the use of the diaper product, the second non-woven fabric layer 5 in the diversion part can tilt up along with the leak-proof side edge 31, forming a current-limiting structure composed of the diversion part and the leak-proof side edge 31 inside the diaper product, thereby restricting the body fluid within the diversion layer and the leak-proof side edge 31. A main absorption groove 6 is formed between the two symmetric diversion parts to absorb the liquid in the first time. At the same time, an antibacterial agent layer 11 is also arranged inside the liquid-permeable surface layer 1. After the body fluid enters the inside of the diaper through the liquid-permeable surface layer 1, the antibacterial effect of the liquid-permeable surface layer 1 can be realized on the premise of sufficient diversion and absorption, ensuring no peculiar smell for a long time, and also protecting the skin on the side in contact with the human body, avoiding the influence of the existing antibacterial agent components on the human skin, so as to fully ensure the comfort during use.

[0025] In terms of structure, in order to improve the diversion rate, a plurality of diversion pressure grooves 51 extending transversely are arranged on the surface of the second non-woven fabric layer 5; the diversion pressure grooves 51 extend transversely. After the body fluid enters the inside of the diaper, it is fully shunted, especially in the case of a large amount of liquid, achieving an effect of fully dispersing and absorbing.

[0026] Although the present utility model is specifically shown and described in connection with preferred embodiments, those skilled in the art should understand that various changes may be made to the present utility model in form and detail without departing from the spirit and scope of the present utility model as defined by the appended claims, and all such changes are within the scope of protection of the present utility model.
