Description

Technical Field

[0001] The utility model belongs to the technical field of sanitary products, and in particular relates to an absorbent product with a side leakage prevention guide groove. Background Art

[0002] Absorbent products include menstrual absorbent products and incontinence absorbent products. They are absorbent materials, and their main materials are high molecular polymers and high molecular polymer composite paper formed by cotton, non-woven fabrics, pulp or composites of the above materials. When women's menstrual period comes, they will feel more stuffy and damp in their genitals, and moisture will accumulate. In such an environment, bacteria are most likely to breed. Surveys show that 73% of women will feel local skin itching and burning pain during menstruation. This is mostly because the use of menstrual absorbent products is slow to absorb menstrual fluid during use, and often adheres to sensitive parts of the human body. If you want to spend your menstrual period safely, it is very important to choose suitable menstrual absorbent products. However, existing menstrual absorbent products still have side leakage when used, resulting in insufficient leakage prevention effect of menstrual absorbent products.

[0003] In addition to improper sleeping posture and underwear that does not fit the body, menstrual leakage and urine leakage are also caused by improper sanitary napkins or incontinence napkins. Existing sanitary napkins and incontinence napkins have an inner core for absorption in the middle, and the edge is composed of wings for connecting with underwear. When sleeping on the side, menstrual blood will flow to one side. Since the side wings do not have moisture-absorbing cotton, the moisture absorption function is poor and it is not easy to absorb liquid. Therefore, menstrual blood is easy to slide to one side when sleeping on the side, causing side leakage. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides an absorbent article with a guide groove for preventing side leakage, and solves the problem that the prior absorbent article is prone to side leakage by providing the guide groove.

[0005] The absorbent product with a side leakage prevention guide groove comprises a main body and a wing part. A guide groove 1 is arranged in the middle of the main body in the same length direction. A guide groove 2 is arranged at four end corners of the guide groove 1 extending in an arc shape toward the side edge of the main body adjacent to it. The guide groove 1 and the guide groove 2 form an x-shaped structure for primary leakage prevention. A guide groove 3 is arranged at both ends of the main body. The guide groove 3 is spaced apart from the guide groove 2 so that a bulge is formed between the two to achieve secondary leakage prevention.

[0006] Furthermore, the main body portion includes a surface layer, a guide layer, a core layer and a bottom film layer from top to bottom, the surface layer is a non-woven fabric material, the bottom film layer is a water-proof film material, the core layer is a composite core or absorbent paper material prepared by wrapping fluff pulp with a high molecular absorbent resin in toilet paper; the wing portion includes a surface layer and a bottom film layer.

[0007] Furthermore, the guide groove 1, the guide groove 2 and the guide groove 3 all penetrate the surface layer, the guide layer and the core layer, and guide the liquid to penetrate into the guide layer and the core layer through the surface layer.

[0008] Furthermore, the guide groove three is a V-shaped structure formed by continuous point embossing, and a plurality of embossing points are continuously arranged at intervals on the V-shaped structure.

[0009] Furthermore, the guide groove 1 is embossed with a width of 4 mm to 12 mm and an absorption hole is provided in the middle; the guide groove 2 is a continuous point embossing with a plurality of embossing points arranged at continuous intervals.

[0010] Furthermore, the pressure point is an inverted cone-shaped pressure point, and the inverted cone-shaped pressure point runs through the surface layer, the guide layer and the core layer.

[0011] Furthermore, the guide groove one, guide groove two and guide groove three are arranged along the same center line, the guide groove one is in the shape of a long strip; the guide groove two is an eight-shaped arc structure extending outward from both ends of the guide groove one; the guide groove three is a V-shaped structure in the same direction as the guide groove two or a V-shaped structure in the opposite direction.

[0012] Compared with the prior art, the utility model has the following advantages: in the present application, a guide groove 1 is provided so that the main body forms a stress concentration and is depressed downward during use, while the left and right sides of the main body are naturally erected, and the guide groove 2 is provided to form a boat shape (or bowl shape), thereby effectively achieving a primary leak-proof effect; in addition, a guide groove 3 is provided, and a bulge is formed between the guide groove 3 and the guide groove 2 to prevent liquid from overflowing backwards. If overflow occurs, the liquid overflowing backwards is absorbed by the guide groove 3 to achieve a secondary leak-proof effect. BRIEF DESCRIPTION OF THE DRAWINGS
