Sanitary napkin

Abstract

The invention provides a sanitary napkin and relates to the technical field of sanitary products.The sanitary napkin is characterized by comparing a surface layer which liquid can permeate, an inner layer, an absorbing core arranged between the surface layer and the inner layer and a bottom layer which liquid cannot permeate, the positions, corresponding to an excretion hole of the human body, of the surface layer, the absorbing core and the inner layer are provided with openings, the parts, around the openings, of the surface layer and the inner layer bond and wrap the absorbing core, the periphery of the surface layer and the periphery of the inner layer are bonded with the bottom layer, and protective wings extend out of the parts, outside bonding lines of the left side and the right side, of the surface layer and the bottom layer which are bonded together.Through the openings, the surface layer and the inner layer can both achieve the absorption effect, the absorption superficial area is increased, a better water absorption effect is achieved, meanwhile, through the openings, the contact area between the surface layer and skin is reduced, the ventilation effect is also achieved, a mode of conducting absorption from inside to outside is adopted, dryness and comfort of the surface layer can be guaranteed better, and the sanitary napkin is more comfortable to use and simple in structure.

Description

technical field [0001] The invention relates to the technical field of sanitary products, in particular to a sanitary napkin with holes on the surface. Background technique [0002] Due to the limited absorption effect of the surface layer and fillers in existing sanitary napkins, menstrual blood often cannot be absorbed in time, causing menstrual blood to flow on the surface, resulting in side leakage or rear leakage. In order to prevent leakage and increase absorption capacity, some sanitary napkins are equipped with There are bumps, but there is a lot of friction on the skin during exercise, which is easy to damage the skin; some simply use the method of thickening, widening and lengthening, although there is a certain effect, the use comfort is poor, and the waste of materials is serious; In addition, direct contact with the skin for a long time has poor air permeability and is likely to cause skin infection and allergies. Therefore, the existing technology still has uns...

Problems solved by technology

[0002] Due to the limited absorption effect of the surface layer and fillers in existing sanitary napkins, menstrual blood often cannot be absorbed in time, causing menstrual blood to flow on the surface, resulting in side leakage or rear leakage. In order to prevent leakage and increase absorption capacity, some sanitary napkins are equipped with There are bumps, but there is a lot of friction on the skin during exercise, which is easy to damage the skin; some simply use the method of thickening, widening and lengthening, although there is a certain effect, the use comfort is poor, and the waste of materials is serious; In addition, direct contact with the skin for a long time, poor air permeability, easy to cause skin infection and allergies, so the existing technology, the use effect is still not satisfactory, there is room for improvement
