And coating, structure glue is provided between above-mentioned neighboring layers, and main core body is provided between the guide layer and gas permeation bottom film, it is described
The central part of main core body is provided with the ventilative collecting and distributing portion of closing of the frontier, and the length in the collecting and distributing portion that breathes freely is at least above the master
The 10% of core body length, width is at least above the 20% of the main core body width, and depth is at least above the main core body thickness
30%。
Preferably, the ventilative collecting and distributing portion top and the main core body flush.
Preferably, it is higher than the main core body surface at the top of the ventilative collecting and distributing portion, the thickness for breathing freely collecting and distributing portion is less than
Twice of the main core body height.
Preferably, the main core body is made up of wood pulp or dust-free paper
Preferably, the air-vent being provided through on the main core body.
Preferably, the size of the air-vent is 0.25-25 square millimeters.
Preferably, the arrangement density of multiple air-vents is less than 50 every square centimeter in unit area.
Preferably, the second core body is also posted in the bottom of the main core body, and second core body is dust-free paper or non-woven fabrics material
Material.
Preferably, the area of second core body is more than or equal to the area in the collecting and distributing portion that breathes freely, second core body
Area is less than or equal to the area of the main core body.
Preferably, be shaped as ventilative collecting and distributing portion be shaped as in rectangle, circle, ellipse the one of the collecting and distributing portion that breathes freely
Kind.
Preferably, the material of the precoat and the guide layer is the non-woven fabrics for having obvious space.
The beneficial effects of the utility model are：Main core body is provided between guide layer and gas permeation bottom film of the present utility model,
The central part of main core body is provided with the ventilative collecting and distributing portion of closing of the frontier, and the collecting and distributing portion that breathes freely is reduced to be also set up on side leakage, main core body
There is air-vent, the combination of ventilative collecting and distributing portion and air-vent substantially improves product and breathed freely in addition to keeping enough absorbabilities
Performance, side leakage risk is reduced while can accelerate juice and absorb.So as to be beneficial to, consumer is physically and mentally healthy, and what lifting was used relaxes
Appropriateness.
