DETAILED DESCRIPTION

[0025] The invention shown in FIG. 1 is an assembled nursing pad, featuring a first 102 breast-shaped lamina made of silicone (or any other washable, flexible, self-adhering, waterproof material) on the concave interior surface of the assembled nursing pad, having an aperture in the silicone lamina. The nursing pad assembly shown in FIG. 1 further comprises a second, 103 cloth lamina adjacent to the convex side of the first lamina and having 101 a nipple contact area protruding through the aperture in the silicone layer, which contact area is larger in diameter than the aperture, allowing the cloth lamina to securely assemble and also make contact with the nipple.

[0026] The invention shown in FIG. 2 is an assembled nursing pad, as in FIG. 1, but showing the convex view with only the 203 cloth lamina visible.

[0027] The invention shown in FIG. 3 is a disassembled nursing pad, separately showing the 302 silicone lamina with its 304 aperture and 303 cloth layers with a 301 nipple contact area.

[0028] The invention shown in FIG. 4 (concave end-view) and FIG. 5 (cross-sectional side-view) is an assembled nursing pad, featuring 402, 502 silicone lamina, 403, 503 cloth layer, and 401, 501 nipple contact area protruding inward through the 504 aperture in the 402, 502 silicone lamina. The 401, 501 nipple contact area has a larger diameter than the 504 aperture in the 402, 502 silicone lamina to allow the cloth layer and silicone lamina to assemble securely. In one embodiment the aperture is in diameter and the nipple contact area is 1 in diameter.

[0029] The further embodiment of the invention shown in FIG. 6 and FIG. 7 shows a composite cloth comprising three cloth sub-layers: 601, 701 a nipple contact cloth sub-layer, 605, 705 a wicking/absorbing cloth sub-layer, and 603, 703 a water resistant/waterproof cloth sub-layer. In particular, FIG. 6 shows the three cloth sub-layers separately (unassembled) and FIG. 7 shows the three cloth sub-layers as assembled.

[0030] The further embodiment of the invention shown in FIG. 8 (concave end-view) and FIG. 9 (cross-sectional side-view) is an assembled nursing pad with performance engineered cloth tri-layer construction. The 802, 902 silicone lamina is assembled securely to the 801, 805, 803, 901, 905, 903 composite tri-layer cloth. The 801, 901 nipple contact area is a comfortable absorbing toweling sub-layer functioning to wick milk through the aperture towards the middle layer via capillary action. The 805, 905 middle layer is an absorbent wicking layer. The 803, 903 outer layer is a water resistant/waterproof surface layer, to protect outer garments from leaking.

[0031] The further embodiment of the invention shown in FIG. 10 is a disassembled nursing pad, separately showing 1002 the silicone lamina and 1001, 1005, 1003 composite cloth sub-layers. The 1002 silicone lamina features 1004 an aperture at its center. In one embodiment the 1004 aperture can be in diameter. The composite cloth comprises three sub-layers: 1001 a nipple contact cloth sub-layer, 1005 a middle absorbent wicking layer, and 1003 a water resistant/waterproof surface layer.
