Breast pad and preparation device

Abstract

The breast pad comprises a body formed by stacking a surface layer, an absorption layer and a bottom layer, the body comprises a middle area and side areas, at least one side area is provided with a wrinkle part, the wrinkle part comprises a plurality of strip-shaped wrinkles arranged at intervals, the strip-shaped wrinkles extend from the side areas to the middle area, the strip-shaped wrinkles comprise end parts facing the middle area, and the end parts face the bottom layer. The extension lines of the plurality of strip-shaped wrinkles from the end parts to the direction of the middle area intersect at the same virtual center point, so that the wrinkles are arranged more densely on one side close to the middle area, and the wrinkles are arranged more sparsely on one side far away from the middle area, on one hand, the breast pad is naturally in a manner that the two sides are bent inwards, and the breast pad is more compact in structure. Due to the three-dimensional shape that the middle part protrudes outwards and the elastic shape formed by the wrinkle part, the bra can adapt to different breast shapes, and the use comfort is improved; in addition, the strip-shaped wrinkles form a flow guide effect, emulsion diffusion is accelerated, and the invention further provides a device for preparing the breast pad.

Description

technical field [0001] The present invention belongs to the field of absorbent articles, in particular to a breast pad and a preparation device thereof. Background technique [0002] Breast pad is a kind of mother and baby product that prevents the milk overflow of breastfeeding women. With the continuous improvement of people's living standards, more and more attention is paid to it. The breast pad needs to be attached to the breast when in use. Therefore, the breast pads also need to be set in a hemispherical shape to adapt to the shape of the breast to improve comfort. [0003] In order to achieve a hemispherical shape, some techniques have been developed, such as using a thermally deformable material such as polyethylene to form a flat circular material on the surface layer located on the outer surface, heating the flat circular material and heating the material. Pressing it on a hemispherical mold for thermoforming, such a product has poor shape retention. Once the hem...

Problems solved by technology

[0003] In order to achieve a hemispherical shape, some technologies have been developed, such as using thermally deformable materials such as polyethylene to form a flat circular material on the surface layer on the outer surface, heating the flat circular material and Press and stick it on the hemispherical mold for heating and molding. Such products have poor shape retention. Once the hemispherical shape is deformed, its fit will become poor and position deviation will occur. For example, in a circle On both sides of the shaped or approximately circular product, gathers made of elastic bodies such as rubber bands are provided in the respective longitudinal directions, thereby forming a hemispherical shape with better shape retention, or the circular absorbent body Cut along one radius or two opposite sides, overlap the fan-shaped area at the cut position and form the joint surface into a hemispherical shape, or set a notch on one side or two opposite sides of the absorber, and cut the part at the notch along the center line of the notch. The surface layers are connected in the direction of mutual bonding to form a hemispherical three-dimensional shape. In this way, the absorber needs to be cut or a gap is formed on the absorber, which is very easy to cause the decline of the absorption performance, especially the absorption capacity. It is difficult to perform rapid or automated production in a form that is greatly affected without cutting the absorber or forming a gap in the absorber
