Abstract

The invention relates to an absorption core body, which comprises a liquid-tight bottom layer, an absorption core and a liquid-permeable surface layer which are sequentially laminated, wherein an elastic material layer is connected between the liquid-tight bottom layer and the absorption core and is formed by arranging a plurality of strip-shaped elastic bodies at intervals along the width direction, a plurality of ventilation through holes are arranged on the absorption core, an annular bulge is arranged on the upper surface of the absorption core, the plurality of ventilation through holes surround and form a plurality of continuous concave parts, the area of each concave part is 1-15 mm, a bulge part is arranged on the upper surface of each strip-shaped elastic body, a plurality of grooves along the width direction are arranged on the bulge part, and the grooves are arranged at intervals along the length direction.

Description

Absorption core body

Technical Field

The present invention relates to an absorbent core.

Background

In the existing absorbent articles such as sanitary napkins, sanitary pads and the like, liquid excreta such as menstrual blood and the like permeate a liquid permeable layer such as a top layer and are absorbed by an absorber, the menstrual blood is high in viscosity and is relatively easy to remain in the liquid permeable layer, when the liquid permeable layer has residual menstrual blood, a user feels sticky when the liquid permeable layer is rubbed with skin, and the menstrual blood with high viscosity is mostly remained in a block shape on the top layer, so that the liquid permeable layer is blocked and completely airtight, the wearer can feel stuffy, moist and the like at the same time, the wearer brings great discomfort to the user, and the resistance is weaker during the vacation of every woman, and the stuffy, moist also brings more gynecological diseases to the woman. The sanitary napkin and the sanitary pad can be made more breathable, the sticky feeling of a wearer is reduced, menstrual blood can quickly reach the absorption core, the sticky feeling is reduced, but the breathability is not really solved because the bottom layer is made of a liquid-tight material or is made of an airtight material.

Disclosure of Invention

The invention aims to provide an absorption core body which is simple in structure, good in air permeability and better in absorption.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides an absorb core, its includes the liquid-tight bottom that stacks gradually, absorbs core, liquid permeability top layer, be connected between liquid-tight bottom and the absorption core and be equipped with the elastic material layer, the elastic material layer is formed along the width direction interval setting by a plurality of strip elastomers, be equipped with a plurality of ventilative through-holes on the absorption core, it is protruding to be equipped with an annular on the absorption core upper surface.

Preferably, the strip-shaped elastomer is acetate fiber or manila hemp.

Preferably, the thickness of the strip-shaped elastomer is 0.1-20 mm.

Preferably, the plurality of vent through holes surround and form a continuous plurality of recesses, the area of each recess being 1 mm-15 mm.

Preferably, the absorbent core surface forms a widthwise undulating surface upon application of a force.

Preferably, the upper surface of each strip-shaped elastic body is provided with a protruding part, the protruding part is provided with a plurality of grooves along the width direction, and the grooves are arranged at intervals along the length direction.

Preferably, the distance between two adjacent strip-shaped elastic bodies is 5-20 mm.

The technical scheme has the following beneficial effects: this absorption core punches and forms multiseriate concave part and has improved the quick speed of permeating to absorbing the core of menses, can reduce the menses that remains in the liquidity top layer, the sticky sense of user's skin has been reduced, and be equipped with the strip elastomer between liquid-tight bottom and absorption core, receive external force factor extrusion when using, the strip elastomer atress is flattened, thereby form the wave shape and improve the space, again because of the liquidity top layer is the gas permeability material, make gaseous follow top layer discharge, make the true completion of absorption body ventilative, the stuffiness can not appear in the wearer, moist, some gynecological diseases of women have also been reduced simultaneously.

Drawings

FIG. 1 is a cross-sectional view of the present invention;

fig. 2 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the drawings and specific embodiments, but the embodiments of the present invention are not limited thereto.

Referring to fig. 1 and fig. 2, the present embodiment provides an absorbent core, which includes a liquid-tight bottom layer 1, an absorbent core 2, and a liquid-permeable top layer 3 stacked in sequence, an elastic material layer is connected between the liquid-tight bottom layer 1 and the absorbent core 2, the elastic material layer is formed by arranging a plurality of strip-shaped elastic bodies 4 at intervals along the width direction, a plurality of ventilation through holes 21 are formed on the absorbent core 2, and an annular protrusion 22 is formed on the upper surface of the absorbent core 2. The strip-shaped elastic body 4 is acetate fiber or manila hemp. The thickness of the strip-shaped elastic body 4 is 3 mm. The plurality of ventilation through holes 21 surround and form a plurality of continuous concave portions 23, and the area of each concave portion 23 is 8 mm. The surface of the absorbent core 2 is formed into a widthwise wavy surface after being subjected to a force. The upper surface of each strip-shaped elastic body 4 is provided with a convex part 41, the convex part 41 is provided with a plurality of grooves 42 along the width direction, and the grooves 42 are arranged at intervals along the length direction. The distance between two adjacent elastic strips 4 is 10 mm.

The thickness of the strip-shaped elastic body can be any value between 0.1 and 20 mm; the area of each recess can also be any value between 1 mm-15 mm; the distance between two adjacent strip-shaped elastic bodies can be any value between 5 and 20 mm.

This absorption core punches and forms multiseriate concave part and has improved the quick speed of permeating to absorbing the core of menses, can reduce the menses that remains in the liquidity top layer, the sticky sense of user's skin has been reduced, and be equipped with the strip elastomer between liquid-tight bottom and absorption core, receive external force factor extrusion when using, the strip elastomer atress is flattened, thereby form the wave shape and improve the space, again because of the liquidity top layer is the gas permeability material, make gaseous follow top layer discharge, make the true completion of absorption body ventilative, the stuffiness can not appear in the wearer, moist, some gynecological diseases of women have also been reduced simultaneously.

The above is only a preferred embodiment of the invention and equivalent and similar modifications will be apparent to those skilled in the art from the following claims.
