Background

The breast pad is a mother and infant article for preventing the breast milk from overflowing during lactation, and is more and more important along with the continuous improvement of the living standard of people, the breast pad needs to be attached to the breast when in use, and the breast pad also needs to be arranged in a hemispherical shape to adapt to the shape of the breast, so that the comfort is improved.

To achieve a hemispherical morphology, several techniques have been developed:

for example, a material that is thermally deformed such as polyethylene is used to form a planar circular material on a surface layer located on an outer surface, and the planar circular material is heated and pressed against a hemispherical mold to be heated and molded, so that the shape retention of the product is poor, and when the hemispherical shape is deformed, the fitting property is deteriorated, and positional displacement is generated;

for example, a dome shape with a better shape retention is formed by providing a gather portion made of an elastic body such as a rubber band on both sides of a circular or nearly circular product in the respective longitudinal directions, and the rubber band provided in this manner is liable to cause a pressing or tightening feeling to the breast, causing discomfort in use;

for another example, the circular absorption layer is cut along one radius or two opposite sides of the absorption layer, and the sector areas at the cutting positions are overlapped and combined with the surface to form a hemispherical shape, so that the absorption performance is greatly influenced due to the cutting of the absorption layer;

for example, a notch is arranged on one side or two opposite sides of the absorption layer, the surface layers at the notch are connected along the center line of the notch to form a joint, and the surface layers are combined to form a hemispherical three-dimensional form.

There is therefore a great need for a breast pad which avoids the above-mentioned risks, is safer to use and is easy to form into a hemispherical shape.
