Description

Adult diaper with three-layer core body

Technical Field

The utility model relates to a health supplies technical field such as panty-shape diapers especially relates to a three-layer core adult diaper.

Background

The paper diaper is a common sanitary product for infants and adult patients, and at present, the structure of the paper diaper on the market generally comprises a liquid-permeable surface layer, a flow guide layer for accelerating liquid diffusion, an absorption core body for absorbing liquid in the middle, a leakage-proof bottom layer for preventing liquid leakage and non-woven fabrics at two sides of the paper diaper for preventing leakage.

The paper diaper has two types of cores, one is a wood pulp core formed by mixing wood pulp and high polymer water-absorbent resin, and the other is a composite core formed by compounding dust-free paper, fluffy non-woven fabric and high polymer water-absorbent resin. At present, the second type is mainly used in the market, but the paper diaper core has the defects of poor diffusivity, poor multiple-time absorption and the like, after the core absorbs urine for multiple times, the conduction and diffusion performance of the core is poor, the core can be completely diffused after a long time, the absorption efficiency is low, the surface of the paper diaper is wet, discomfort is caused to infants, and even more, the skin of the infants generates rubella.

The existing paper diaper with double cores is usually formed by compounding a wood pulp core formed by mixing two layers of wood pulp and high polymer water-absorbent resin, but the double-core structure has the defects of over-thick core, unconcentrated absorption, poor surface dryness and comfort, poor integrity after the core is used and easy layer breaking.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model designs a three-layer core adult diaper.

The utility model adopts the following technical scheme:

the utility model provides a three-layer core adult diaper, including liquid-permeable surface course, the middle absorption sandwich layer that absorbs liquid, prevent the leak protection bottom of liquid leakage and be located the leak-proof both sides non-woven fabrics in diaper both sides, it includes three-layer core structure to absorb the sandwich layer, the compound core on upper strata, the polymer resin layer that absorbs water of intermediate level equipartition and the wood pulp style core of lower floor, the compound core covers the mid portion of wood pulp style core, the polymer resin layer that absorbs water is attached central point between compound core and wood pulp style core puts.

Preferably, the composite core is formed by compounding dust-free paper, fluffy non-woven fabric and high polymer water-absorbent resin.

Preferably, the wood pulp core is formed by mixing wood pulp and high polymer water-absorbent resin.

Preferably, the polymeric water-absorbent resin is polymeric SAP particles.

Preferably, the inner sides of the non-woven fabrics at the two sides are turned over and wrapped with rubber bands to form a three-dimensional enclosure, and the three-dimensional enclosure is turned over outwards.

Preferably, the leakage-proof bottom layer comprises a bottom layer non-woven fabric outside the bottom film.

Preferably, two side waist tapes are arranged on two sides in the bottom layer non-woven fabric.

Preferably, the bottom layer non-woven fabric is provided with an elastic waistline.

The utility model has the advantages that: (1) the adult diaper with the three-layer core body is provided with the three-layer core body structure, so that the effective absorption area is increased, the concentrated absorption is realized, and the dryness is increased; (2) the core body has good integrity after being used, is not layered continuously, is thinner and is more comfortable to use.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of a layered structure of the present invention;

in the figure: 1. two-side non-woven fabrics, 2, a composite core body, 3, a high-molecular water-absorbent resin layer, 4, a wood pulp core body, 5, a three-dimensional enclosure, 6, two-side waist patches, 7, an elastic waistline, 8, a surface layer, 9 and a bottom non-woven fabric.

Detailed Description

The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:

example (b): as shown in attached figures 1 and 2, the three-layer core adult diaper comprises a liquid-permeable surface layer 8, a middle liquid-absorbing absorption core layer, a leakage-proof bottom layer for preventing liquid leakage and two-side non-woven fabrics 1 which are positioned on two sides of the diaper and are used for preventing leakage, wherein the absorption core layer comprises a three-layer core structure, an upper-layer composite core body 2, a middle-layer uniformly-distributed high-molecular water-absorbent resin layer 3 and a lower-layer wood pulp core body 4, the composite core body covers the middle part of the wood pulp core body, and the high-molecular water-absorbent resin layer is attached to the central position between the composite core body and the wood pulp core body. The composite core body is formed by compounding dust-free paper, fluffy non-woven fabric and high polymer water-absorbent resin. The wood pulp core body is formed by mixing wood pulp and high polymer water-absorbent resin. The high molecular water-absorbent resin is high molecular SAP particles. The inner sides of the non-woven fabrics at the two sides are turned over and wrapped with rubber bands to form a three-dimensional enclosure 5, and the three-dimensional enclosure is turned over outwards. The leakage-proof bottom layer comprises a bottom film and bottom non-woven fabrics 9 outside the bottom film. Two sides of the bottom layer non-woven fabric are provided with two side waist tapes 6. The bottom layer non-woven fabric is provided with an elastic waistline 7.

The adult diaper with the three-layer core body has the use principle that: the dry degree is ensured to the compound core, once absorbed mass is big, and the polymer resin layer that absorbs increases the active absorption area, concentrates the absorption, and wood pulp style core diffusivity is good, and the diffusion is absorbed, increases the active absorption area to the polymer resin layer that absorbs of upper strata, intermediate level equipartition and the wood pulp style core of lower floor mutually support the absorption. Simultaneously, the three layers of cores are mutually matched, so that the absorption capacity is ensured, and compared with other core structures, the requirement of thinner core and more comfortable use is met.

The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the scope of the claims.
