Abstract

The invention relates to an anti-overflow dry and comfortable breast pad. The anti-overflow dry and comfortable breast pad comprises an anti-overflow dry and comfortable functional layer, wherein theanti-overflow dry and comfortable functional layer sequentially comprises an anti-overflow layer connected with a surface layer and a water absorption layer connected with a bottom film, the anti-overflow layer comprises a waterproof bottom layer which is connected with the water absorption layer and provided with an opening, a base layer arranged on the surface of the side, away from the water absorption layer, of the waterproof bottom layer, and a hydrophobic layer connected with the base layer. The anti-overflow dry and comfortable breast pad is advantaged in that the anti-overflow layer isarranged between the surface layer and the absorption layer of the breast pad, and the anti-overflow layer structure not only has the function of guiding breast milk into the absorption layer more quickly, but also has the effect of solving the problem of excessive breast milk exudation, so the surface layer of the breast pad is always kept dry and comfortable in the use process.

Description

technical field [0001] The invention belongs to the technical field of sanitary products, and in particular relates to an anti-spill dry breast pad. Background technique [0002] Nursing pads are used to prevent milk leakage during breastfeeding. It can absorb and lock breast milk, so as to keep the bra dry and avoid unnecessary embarrassment. The disposable anti-galactorrhea pad in the prior art is combined with a non-slip film layer, a breathable and waterproof outer layer, a water-locking layer and a lining. [0003] For example, the application number is CN202999323U, which consists of hydrophilic non-woven fabric, waterproof bottom film and absorber. The two ends of the gap formed by folding in half are fixed by embossing heat sealing. The elastic is fixed by the rubber section, so that the breast pad can form a three-dimensional shape that is easier to fit. Breast pads have fixed flow embossing around the center. On the production line for producing the above-mentio...
