Description

Breast pad

Technical Field

The utility model relates to the technical field of sanitary products, in particular to a breast pad without corner sealing parts.

Background

Patent document CN101299936a discloses providing a breast milk pad. The breathable waterproof sheet is formed by laminating a breathable waterproof sheet, a top sheet and an absorber arranged between the top sheet and the breathable waterproof sheet, wherein the top sheet and the breathable waterproof sheet are joined at peripheral edge parts, cut-out parts are respectively formed at positions opposite to each other in the peripheral edge parts, and the top sheet and the breathable waterproof sheet are joined inside the cut-out parts; the joining portion is formed by folding the top sheet along a folding line connecting the facing cut portions so that the top sheet becomes an inner surface, and joining the inner surfaces of the top sheet overlapping each other in the cut portions in the folded state.

The above prior art breast pad has the following disadvantages: after the materials of the layers in the cut parts are bonded and molded, the formed bonded parts (namely the corner sealing parts) have high hardness and are relatively brittle, are easy to break and scratch the skin when in use.

Patent document CN216933734U discloses a breast pad with good corner seal flexibility, comprising a top sheet, a water-absorbing layer and a bottom sheet which are laminated in sequence; the outer edges of the top sheet and the bottom sheet are joined to each other to wrap the water-absorbent layer and form a wrap; the outer side of the bottom sheet is provided with a breathable water-repellent film for preventing liquid from penetrating; the edge of the water absorption layer is provided with one or a pair of symmetrically distributed notches; the top sheet and the bottom sheet are symmetrical in appearance and dimension, and openings corresponding to the notch positions are also formed in the top sheet and the bottom sheet; and after the inclusion is folded towards one side of the top sheet by taking the central line of the notch as a folding line, the air permeable and water repellent films attached to the opening are joined to form a joint part (namely a corner seal part). The corner seal is formed by joining only the breathable water repellent film. The disadvantage of the breast pad disclosed in this document is that: the corner seal is formed by joining only the breathable water-repellent film, and is easy to break during use, thereby causing leakage of the polymer material.

In the breast pad in the prior art, the adopted water absorption layers are provided with the gaps, so that the volume of the water absorption body is reduced, and the water absorption amount is reduced; meanwhile, more waste materials can be generated when the notch is cut, and the environment protection is not facilitated.
