Description

Absorbent article with novel edge-separating protective enclosure

Technical Field

The utility model relates to a health supplies related product field, concretely relates to absorption article with novel separate limit and protect and enclose.

Background

In the field of disposable sanitary products, there are currently two specific structures for the side leakage guards of disposable sanitary napkins: the first is to widen the material of the apron, then fold back and fix the apron on the main body of the sanitary towel, and the apron structure has no certain height, so the side leakage prevention effect is not ideal; secondly, a plurality of rubber bands are added on the protecting wall material, the rubber bands are wrapped by glue and then turned outwards and then fixed on the sanitary towel main body, and a three-dimensional protecting wall with a certain height is formed when the rubber bands are stretched; in the prior art, for example, CN 112076023 a shows a preparation process of the prior leak-proof separation edge:

1) unreeling the processed rolled water-repellent non-woven fabric, defining that the water-repellent non-woven fabric extends to a longitudinal direction along the unreeling and conveying direction of the water-repellent non-woven fabric, and extends to a transverse direction along the width direction of the water-repellent non-woven fabric;

2) unreeling a processed roll-shaped elastic shrinkage material, spraying glue to the elastic shrinkage material at intervals through a spray gun, and compounding the elastic shrinkage material on a water-repellent non-woven fabric, wherein a compounding area is positioned in the transverse middle of the water-repellent non-woven fabric, the area compounded through spraying the glue is a first glue applying area, the distance between the upper ends of two adjacent first glue applying areas in the longitudinal direction is the length size of a single leakage-proof partition edge, one surface of the water-repellent non-woven fabric compounded with the elastic shrinkage material is defined as a front surface, the other surface opposite to the front surface is a back surface, one transverse side of the water-repellent non-woven fabric positioned with the elastic shrinkage material is defined as a left side area, and the other transverse side of the water-repellent non-woven fabric positioned with the elastic shrinkage material is defined as a right side area;

3) continuously spraying glue on the left side area of the front surface of the water-repellent non-woven fabric and the position, close to the elastic shrinkage material, of the water-repellent non-woven fabric through a spray gun along the longitudinal direction, wherein the glue spraying area is a second glue applying area, the transverse width size of the second glue applying area is 2-15 mm, then turning the water-repellent non-woven fabric upwards along the boundary of the elastic shrinkage material and the right side area, and the turning line is a first turning line, so that the left side area and the right side area of the water-repellent non-woven fabric are in composite connection at the second glue applying area;

4) the left side area of the water-repellent non-woven fabric is folded downwards along the boundary of the left side area and the second glue applying area, so that the back surface of the second glue applying area is attached to the back surface of the left side area, the folding line is a second folding line, and the second folding line is attached to the front surface of the right side area;

5) spraying glue to an area, which is not covered by the second glue applying area, on the reverse side of the left side area of the water-repellent non-woven fabric through a spray gun, wherein the glue spraying area is a third glue applying area, and then the right side area of the water-repellent non-woven fabric is downwards folded along the boundary of the right side area and the second glue applying area, and the folding line is a third folding line, so that the reverse side of the left side area and the reverse side of the right side area of the water-repellent non-woven fabric are in composite connection at the third glue applying area;

6) and (5) cutting the product in the step (5) along the longitudinal middle part of the first glue application area to form a single leakage-proof separation edge.

It can be seen that the whole manufacturing process is complex in process, low in production difficulty and high in material cost.

Secondly, in order to prevent front and back leakage and side leakage of excrement, the disposable diaper pants and the disposable nursing mattress are fixed after a layer of non-woven fabric material is added on the main body of the product, and the mode is the same as that of the disposable sanitary towel, so that the disposable diaper pants and the disposable nursing mattress do not have a certain height, and the effect of preventing the side leakage is not ideal;

when the disposable diaper or the pull-up diaper, the female menstrual period pants and other products are worn, if the leakage-proof protective enclosure is too loose, the side leakage is easy to occur, and if the leakage-proof protective enclosure is too tight, the phenomenon of leg tightening occurs, because the rubber band of the leakage-proof protective enclosure is very thin, usually between 560 and 620 denier, the thin rubber band becomes thinner after being stretched, and the long-time wearing causes pressure on the leg, so that the comfort is reduced.
