[0023] See also Figure 1 , Figure 1 It is a schematic structural diagram of the first embodiment of the absorbent product of the present invention.

[0024] The absorbent article 100 of this embodiment includes an absorbent body 150 , a conduit mechanism 140 and a drawstring 130 .

[0025] The absorbent body 150 includes an absorbent core 110 and a core wrap 120, which is positioned around the absorbent core 110. The absorbent core 110 is made of organic cotton fibers, and the core wrap 120 is made of an organic cotton spunlace nonwoven fabric. The core wrap 120 is primarily an organic cotton spunlace nonwoven fabric woven using a spunlace process.

[0026] Organic cotton fiber and organic cotton spunlace non-woven fabric are pure natural and pollution-free cotton. In agricultural production, organic fertilizers, biological pest control, and natural farming management are mainly used. The use of chemical products is not allowed, and the production and spinning process is also required to be pollution-free. They have ecological, green, and environmentally friendly characteristics.

[0027] The absorbent core 110 is the main liquid-absorbing structure of the absorbent article 100. It has high water absorbency, can quickly absorb liquid, and is in a compressed structure. When inserted, it has a small volume, and after adsorbing liquid, it swells to store the liquid, preventing liquid leakage. The core wrapping cloth 120 wraps the outer periphery of the absorbent core 110 to prevent the absorbent core 110 from becoming loose after soaking in liquid, resulting in fluffs falling off and remaining in the body, improving the integrity of the absorbent core 110 and facilitating insertion into and removal from the body.

[0028] By setting the absorbent core 110 as organic cotton fiber and the core wrapping cloth 120 as organic cotton spunlace non-woven fabric, chemical residues in the absorbent main body 150 are reduced through natural organic materials, the material sensitization is reduced, and the safety of the absorbent article 100 is improved.

[0029] The catheter mechanism 140 is a tubular structure with openings at both ends, and an accommodation cavity 143 is formed therein; the absorbent main body 150 is placed in the accommodation cavity 143. When using the absorbent article 100, the catheter mechanism 140 is placed in the body, and the absorbent main body 150 is pushed out through the catheter mechanism 140, and then the catheter mechanism 140 is taken out, so that the absorbent main body 150 is placed in the body for liquid absorption.

[0030] One end of the drawstring 130 is connected to one end of the absorbent core 110, and the other end of the drawstring 130 extends in the accommodation cavity 143 until it is exposed from the opening on the side of the catheter mechanism 140 away from the absorbent main body 150. The drawstring 130 is used to pull out the absorbent main body 150 from the body after the absorbent main body 150 finishes use.

[0031] With the above structure, the absorbent article of this embodiment includes: an absorbent main body, a catheter mechanism, and a drawstring. The absorbent main body includes an absorbent core and a core wrapping cloth, and the core wrapping cloth is disposed around the absorbent core in a surrounding and fitting manner; the absorbent core includes organic cotton fiber, the core wrapping cloth includes organic cotton spunlace non-woven fabric, the catheter mechanism is a tubular structure with openings at both ends, an accommodation cavity is formed therein, the absorbent main body is placed in the accommodation cavity, one end of the drawstring is connected to one end of the absorbent core, and the other end of the drawstring extends in the accommodation cavity until it is exposed from the opening on the side of the catheter mechanism away from the absorbent main body, so that by setting the absorbent core as organic cotton fiber and the core wrapping cloth as organic cotton spunlace non-woven fabric, chemical residues in the absorbent main body are reduced through natural organic materials, the material sensitization is reduced, and the safety of the absorbent article is improved.

[0032] In some embodiments, the core wrapping cloth 120 is softened with cream; wherein, the core wrapping cloth 120 is sprayed with cream and dried until the moisture-proof rate of the core wrapping cloth 120 ranges from 1% to 5%, and the addition amount of the cream ranges from 10% to 35%.

[0033] Among them, the drying temperature range is 65 - 75 degrees Celsius, specifically it can be 65 degrees Celsius, 68 degrees Celsius, 70 degrees Celsius, 73 degrees Celsius, 75 degrees Celsius, etc., and it is specifically set based on actual requirements. The addition amount range of the cream is 10% - 35%, specifically it can be 10%, 15%, 20%, 23%, 28%, 29%, 31%, 34%, 35%, etc. This addition amount refers to the absolute dry mass ratio of the cream relative to the core wrapper 120. For example: if the core wrapper 120 is 100g and the addition amount of the cream is 20%, then the added weight of the cream is 20g. This is only for example and not for limitation.

[0034] In a specific application scenario, the cream can be configured into a solution, and then the cream solution is evenly sprayed onto the core wrapper 120. The concentration of the solution is not limited, but it is necessary to ensure that the absolute dry addition amount range of the cream is 10% - 35%.

[0035] The core wrapper 120 is softened by the cream, and the core wrapper 120 directly contacts the human body during use, thereby reducing the foreign body sensation of the user by improving the softness and comfort of the core wrapper 120.

[0036] In some embodiments, the grammage range of the core wrapper 120 is 25 gsm - 50 gsm (grams per square meter, Gramme / Square Meter). Specifically, it can be 25 gsm, 28 gsm, 30 gsm, 32 gsm, 35 gsm, 38 gsm, 40 gsm, 41 gsm, 45 gsm, 48 gsm, 50 gsm, etc.

[0037] The core wrapper 120 within this grammage range can provide a better core wrapping effect, reduce the problem of lint shedding, and quickly divert the liquid into the absorbent core 110 for storage, improving the absorption efficiency of the absorbent article 100.

[0038] In some embodiments, the absorbent core 110 includes but is not limited to a multi - layer spiral winding structure, a cylindrical structure, an oval structure, a spherical structure, a V - shaped structure, an umbrella - shaped structure, a rectangular structure, a fan - shaped structure, etc. Among them, the absorbent core 110 with a multi - layer spiral winding arrangement can increase the surface area, thereby increasing the liquid absorption area, improving the liquid absorption speed of the absorbent core 110, and preventing liquid leakage. And the absorbent core 110 is a high - density compressed cotton core, which can achieve the dual functions of rapid absorption and anti - side leakage. The V - shaped structure is initially cylindrical and will expand to both sides after absorbing liquid, resembling a V - shape. The umbrella - shaped structure is initially cylindrical and will expand to form an umbrella - shape with one end large and one end small after absorbing liquid. The rectangular structure is initially cylindrical and will expand to both sides to form a rectangular structure after absorbing liquid; the fan - shaped structure will expand to form a fan - shape after absorbing liquid.

[0039] In some application scenarios, linear or twill indentations can also be provided on the surface of the absorbent core 110 to further improve the diversion effect.

[0040] The porosity of the core wrapper 120 ≥ 85%, and specifically can be 85%, 88%, 90%, 92%, 94%, 96%, 97% or 99% etc., to further improve the liquid absorption speed and liquid conduction speed of the core wrapper 120 and reduce the occurrence of liquid leakage.

[0041] In some embodiments, the material of the catheter mechanism 140 includes thermoplastic polyurethane (TPU), polyethylene (PE) or silicone; the plasticizer content < 0.1%. The above materials have certain biocompatibility, can reduce the biological stimulation reaction, reduce the sensitization or irritation of the user, and improve the safety of the absorbent article 100.

[0042] In some embodiments, a smooth coating is provided on the inner wall of the accommodation cavity 143 of the catheter mechanism 140, and corrugated anti-slip patterns are provided on the outer surface of the catheter mechanism 140.

[0043] Among them, the roughness Ra of the smooth coating ≤ 0.2 μm, so as to be able to smoothly push the absorbent body 150 out of the catheter mechanism 140 and reduce the pushing difficulty. The corrugated anti-slip patterns on the outer surface of the catheter mechanism 140 can reduce the friction coefficient of the outer surface of the catheter mechanism 140 by 40%, so as to smoothly push the catheter mechanism 140 into the body and reduce the discomfort during this process.

[0044] In some embodiments, the drawstring 130 is of a flat braided structure, with uniform contact skin pressure distribution to avoid indentations. The diameter range is 0.6 - 1.0 mm, and specifically can include but not be limited to 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1.0 mm etc. The braided structure can improve the drawstring strength of the drawstring 130 and reduce the risk of drawstring breakage.

[0045] The material of the drawstring 130 includes polyester fiber. Although most of the drawstring 130 is exposed outside the body during use, some areas will still come into contact with the body. The above materials have certain biocompatibility, can reduce the biological stimulation reaction, reduce the sensitization or irritation of the user, and improve the safety of the absorbent article 100.

[0046] The drawstring 130 with the above materials and structure can be compatible with safety and tensile strength, and improve the reliability of the absorbent article 100.

[0047] In some embodiments, the peripheral surface of the drawstring 130 is coated with a beeswax layer; wherein, the thickness range of the beeswax layer is 10 - 15 microns, specifically including but not limited to 10 microns, 11 microns, 12 microns, 13 microns, 14 microns, or 15 microns, etc. The beeswax layer contains carnauba wax and tea tree essential oil in a mass ratio of 9:1, with both antibacterial and anti-slip functions, improving the breaking strength of the drawstring 130.

[0048] Through the setting of the beeswax layer, the surface smoothness of the drawstring 130 is improved, the foreign body sensation and material sensitization are reduced, and the breaking strength of the drawstring 130 is enhanced, improving the safety of the drawstring 130.

[0049] In some embodiments, the catheter mechanism 140 includes a main catheter 142 and a catheter handle 141.

[0050] The main catheter 142 is a tubular structure with openings at both ends. An accommodation cavity 143 is provided inside the tubular structure. One end of the catheter handle 141 extends into the main catheter 142 from the opening at one end of the main catheter 142, and can move relative to the main catheter 142 to discharge the absorbent body 150 inside the main catheter 142 from the opening at the other end of the main catheter 142.

[0051] When using the absorbent article 100, first place the catheter mechanism 140 in the body, and then push the catheter handle 141 inward to discharge the absorbent body 150 from the opening at the other end of the main catheter 142, place it in the body, and then remove the catheter mechanism 140, leaving the drawstring 130 outside the body.

[0052] Please refer to Figures 2 - 3 , Figure 2 which is a schematic diagram of the contraction structure of the second embodiment of the absorbent article of the present invention. Figure 3 which is a schematic diagram of the extended structure of the third embodiment of the absorbent article of the present invention.

[0053] The structures of the absorbent body 250 and the drawstring of the absorbent article 200 in this embodiment are the same as those in the previous embodiments. Please refer to the previous text and will not be elaborated here.

[0054] The catheter mechanism 240 in this embodiment includes a main catheter 243, an auxiliary catheter handle 242, and a main catheter handle 241.

[0055] The main catheter 243 is a tubular structure with openings at both ends. An accommodation cavity is provided inside the tubular structure. One end of the auxiliary catheter handle 242 extends into the main catheter 243 from the opening at one end of the main catheter 243 and is slidably arranged with the main catheter handle 241. The other end of the auxiliary catheter handle 242 is an opening, and the main catheter handle 241 is inserted therein, and the main catheter handle 241 can move relative to the auxiliary catheter handle 242.

[0056] Wherein, a fastening member (not shown in the figure) is disposed inside the side of the auxiliary catheter handle 242 away from the main catheter 243. The initial state of the catheter mechanism 240 is in a contracted state, that is, the auxiliary catheter handle 242 and the main catheter handle 241 are overlapped. When the end of the main catheter handle 241 close to the main catheter 243 moves to the side of the auxiliary catheter handle 242 away from the main catheter 243, it is fixed to the fastening member. At this time, the catheter mechanism 240 extends, and the auxiliary catheter handle 242 can receive the force applied from the main catheter handle 241 to move relative to the main catheter 243 and discharge the absorption body 250 in the main catheter 243 from the other end opening of the main catheter 243.

[0057] The telescopic and fixable settings of the auxiliary catheter handle 242 and the main catheter handle 241 can shorten the overall length of the catheter handle without affecting the propulsion function, thereby shortening the length of the entire absorbent article 200, which is beneficial to the miniaturization and convenience of the absorbent article 200.

[0058] In some embodiments, the opening on the side of the main catheter away from the drawstring is a water-drop-shaped gradually deformed opening, which can be applied to Figure 1 the main catheter 142 in Figure 2 or the main catheter 243 in . The radius of curvature ranges from 4 to 6 millimeters, specifically, it can be 4 millimeters, 5 millimeters, 6 millimeters, etc. The above settings match the physiological shape of the vagina, and the insertion force can be less than 2.5 N, which improves the convenience of use.

[0059] Through the above structure, the absorbent article of this embodiment reduces the chemical residues in the body-inserted absorbent article through organic materials, low-irritation catheters, and drawstrings coated with beeswax, solves the unsafe problems such as material sensitization, and the core wrap is softened to reduce the frictional foreign body sensation during use and removal, achieving a feeling-free use.

[0060] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0061] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
