A liquid storage groove is formed in the core body and located at the end of the arc-shaped groove. When a human body discharges liquid onto the core body, the liquid permeates towards the side wall of the flow guide groove and flows along the length direction of the flow guide groove under the guidance of the flow guide groove, so that the permeation speed of the liquid on the core body is accelerated, and when the liquid is drained to the end part of the flow guide groove, the liquid is collected at the end part of the flow guide groove; at the moment, the liquid at the moment is drained to the two sides of the flow guide groove through the arc-shaped grooves, so that gathering of the liquid at the end of the flow guide groove is reduced, meanwhile, due to the fact that the concave arc faces of the two arc-shaped grooves are oppositely arranged, the liquid is concentrated, and the situation that the liquid permeates to the two ends of the core body and leaks is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of nursing products, in particular to a nursing product with a guide groove. Background Art

[0002] Nursing products include sanitary napkins, baby diapers, and adult absorbent pads. The absorbent core is a highly absorbent material primarily made of cotton, non-woven fabric, pulp, or a combination of these materials, including polymers and polymer-polymer composite paper.

[0003] Among them, the surface layer of existing sanitary products is generally made of non-woven fabrics and chemical fiber materials. Because they are not pure cotton, consumers have a poor experience during use. In order to improve the safety of sanitary napkin products, higher-density materials are generally used to improve comfort. However, high-density materials have a relatively slow absorption rate. When the amount of liquid suddenly increases, it exceeds the full-load diversion capacity and easily causes liquid leakage. Therefore, grooves are cut on the core body. However, the existing groove method often sets a straight groove in the middle. The liquid at both ends of the straight groove will penetrate to the two ends of the core body and easily penetrate to the outside. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present invention is to provide a care product with a guide groove to reduce the amount of liquid penetrating to the two ends of the core.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a care product with a guide groove, comprising a surface layer, a core body and a leak-proof layer, an adhesive layer is provided at the bottom of the leak-proof layer, a guide groove is provided in the middle of the core body along the length direction of the core body, arc grooves are provided on the core body and at both ends of the guide groove, the two concave arc surfaces of the arc grooves are arranged opposite to each other, and a liquid storage tank is provided on the core body and at the ends of the arc groove.

[0006] Furthermore, a first woven fabric composite layer adapted to the guide groove is installed on a side of the core body away from the guide groove.

[0007] Furthermore, a second woven fabric composite layer adapted to the arc-shaped groove and the liquid storage tank is installed on the side of the core body away from the guide groove.

[0008] Furthermore, a buffer circular groove is provided on the core body and located at the guide groove.

[0009] Furthermore, side wings are provided on the left and right sides of the leakage-proof layer, and adhesive layers for adhering to the skin are installed on the side wings.

[0010] Furthermore, a third woven fabric composite layer adapted to the buffer circular groove is installed on the side of the core body away from the guide groove.

[0011] Compared with the prior art, the beneficial effect of the present invention is that when the human body discharges liquid onto the core body, the liquid will first penetrate the side wall of the guide groove while flowing along the length direction of the guide groove under the guidance of the guide groove, thereby accelerating the penetration speed of the liquid on the core body. When the liquid is drained to the end of the guide groove, it will be gathered at the end of the guide groove. At this time, the liquid at this time is drained to both sides of the guide groove through the arc groove, thereby reducing the accumulation of liquid at the end of the guide groove. At the same time, because the concave surfaces of the two arc grooves are arranged relative to each other, the liquid drained by the arc groove will flow toward the middle of the core body, thereby concentrating the liquid and reducing the liquid from penetrating to the two ends of the core body and causing leakage.

[0015] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1 This embodiment provides a care product with a guide groove, including a surface layer 1, a core body 2 and a leak-proof layer 3, and an adhesive layer is provided at the bottom of the leak-proof layer 3.

[0017] To facilitate the drainage of liquid and prevent excessive accumulation of liquid, which may cause side leakage.

[0018] A guide groove 4 is provided in the middle of the core body 2 along the length direction of the core body 2, and arc grooves 5 are provided on the core body 2 and at both ends of the guide groove 4. The concave surfaces of the two arc grooves 5 are arranged opposite to each other, and a liquid storage tank 6 is opened on the core body 2 and at the ends of the arc groove 5.

[0019] When the human body discharges liquid onto the core 2, the liquid will first penetrate the sidewalls of the guide groove 4 under the guidance of the guide groove 4 while flowing along the length direction of the guide groove 4, thereby accelerating the penetration speed of the liquid on the core 2. When the liquid is drained to the end of the guide groove 4, it will be gathered at the end of the guide groove 4. At this time, the arc groove 5 drains the liquid on both sides of the guide groove 4, thereby reducing the accumulation of liquid at the end of the guide groove 4. At the same time, because the concave surfaces of the two arc grooves 5 are arranged oppositely, the liquid drained by the arc groove 5 will flow toward the middle of the core 2, thereby concentrating the liquid and reducing the liquid from penetrating to the two ends of the core 2 and causing leakage. The liquid storage tank 6 is set to increase the liquid storage capacity when there is a lot of liquid accumulation.

[0020] See also Figure 2 A first woven fabric composite layer 7 adapted to the guide groove 4 is installed on the side of the core body 2 away from the guide groove 4.

[0021] Since more liquid is gathered in the guide groove 4, the liquid penetration in the guide groove 4 is larger. In order to increase the liquid absorption in the guide groove 4, a corresponding first woven composite layer 7 is provided at the guide groove 4 to increase the absorption capacity.

[0022] A second woven fabric composite layer 8 adapted to the arc-shaped groove 5 and the liquid storage groove 6 is installed on the side of the core body 2 away from the guide groove 4 .

[0023] Similarly, in order to increase the liquid absorption capacity at the arc-shaped groove 5 , a second woven composite layer 8 is correspondingly provided.

[0024] A buffer groove 9 is provided on the core 2, located at the guide groove 4. This groove 9 corresponds to the vaginal opening and serves as a buffer to prevent liquid from overflowing the guide groove 4 and causing leakage, as it accumulates large amounts of liquid. Antibacterial material can also be added to the buffer groove 9 to reduce infection at the vaginal opening.

[0025] Side wings 10 are provided on the left and right sides of the leakage-proof layer 3 , and adhesive layers for adhering to the skin are installed on the side wings 10 .

[0026] In order to facilitate the accurate positioning of the buffer groove 9 at the vaginal opening, the side wings 10 and the adhesive layer are provided to position the buffer groove 9, ensuring that most of the liquid flows into the buffer groove 9 and then into the guide groove 4.

[0027] A third woven fabric composite layer 11 adapted to the buffer circular groove 9 is installed on the side of the core body 2 away from the guide groove 4 .

[0028] Similarly, in order to increase the liquid absorption capacity at the buffer circular groove 9, a third woven fabric composite layer 11 is correspondingly provided.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
