  • Patent number: 8221373
    Abstract: A breast-milk pad can be produced relatively easily, such that it reduces an uncomfortable sensation to the skin surface of a user, and has excellent shape retention properties. A method for producing the breast-milk pad is also disclosed. The breast-milk pad can include a material that is made up by stacking: a back sheet that prevents permeation of liquid; a top sheet that contacts the body; and an absorber that is disposed between the back sheet and the top sheet. The top sheet and the back sheet are bonded to each other in an outer peripheral portion. Cutout portions obtained by cutting the absorber can be formed in positions facing each other at the outer peripheral portion such that cutout width of each of the cutout portions gradually narrows down inwardly.

  • Publication number: 20050256472
    Abstract: An absorptive product can form and hold a stereoscopic shape which is properly formed to be snugly fitted on a complicated three-dimensional shape of a user's body to prevent leaking of an evacuated body fluid or the like to the outside of the body. The absorptive product includes a back sheet which has a shape elongated in one direction and prevents the permeation of liquid, a liquid permeable surface material (28) which is arranged on a surface side which is brought into contact with a body, and an absorbent (23), (33) which is arranged between the back sheet and the surface material and absorbs and holds the liquid which permeates the surface material.
