Description

[0001] The present invention relates to a pad including multiple SAP sheets and a method of manufacturing the same.

The present invention relates to a pad including multiple SAP sheets and a method of manufacturing the same. More particularly, the present invention relates to a pad having multiple SAP sheets, To a pad comprising a SAP sheet and to a method of making the same.

A sanitary pad is a pad used during periods other than the menstrual period of a woman.

Such a sanitary pad is used for treating a physiological phenomenon such as cold or cold discharge during the rest of the period excluding the menstrual period, that is, before and after menstruation, ovulation day, and gestation period.

However, the sanitary pads are limited solely for the purpose of treating such secretions, thus limiting the functionality of the sanitary pads.

In addition, the structure of the sanitary pad formed by the back sheet, the absorbent layer and the top sheet is formed in a flat structure. When the absorbent layer absorbs the secretion in the absorbent layer and is activated, the absorbent layer is inflated. At this time, The absorbing function is concentrated on only one side, or the absorbing layer is inflated with a nonuniform distribution, thereby causing inconvenience in wearing feeling.

For example, as shown in FIG. 9, the second absorbing layer 400 is formed on an airlaid layer 300 including the first absorbing layer 200 therein. At this time, the second absorbing layer 400 may be located at the center of the upper portion of the airlaid layer 300.

Since the second absorbent layer 400 is formed on the upper / upper surface of the airlaid layer 300 at a position where absorption of the secretion is concentrated, the first absorbent layer 200 and the second absorbent layer 300 The absorptive function for the secretion can be performed through the absorptive layer 400.

10, the swelling of the absorbent layer may be irregular according to absorption of the secretion in the absorbent layer according to the related art, so that the first absorbent layer 200, The swelling phenomenon of the first absorbent layer 200 and the second absorbent layer 400 is concentrated at the center as shown in FIG. 11, So that the feeling of comfort can be further improved (S740).

Then, a topsheet 500 is formed on top of the second absorbent layer 400. Here, the topsheet 500 includes a surface layer formed with a plurality of air holes (or holes) or stripe-shaped ventilation holes so that the secretions can be absorbed.

That is, the topsheet 500 is formed on the second absorbing layer 400 to surround the second absorbing layer 400 and a part of the airlaid layer 300.

For example, as shown in FIG. 12, the topsheet 500 is formed on the second absorbent layer 400.

At this time, the breathable back sheet 100 and the top sheet 500 are formed such that the secretion is absorbed (or embedded) in the first absorbent layer 200 and / or the second absorbent layer 400, (100) and the topsheet (500) so that the second absorbent layer (400) is not exposed to the outside, and a space sealed by the breathable backsheet (100) Can be heat-sealed.

For example, as shown in FIG. 12, the topsheet 500 contacting the breathable backsheet 100 may be joined (S750) by thermal fusion.

<Examples>

The pad 10 including the multiple SAP sheets according to the embodiment of the present invention may be formed by forming the airlaid layer 300 so as to enclose the first absorbent layer 200 and wrapping the first absorbent layer 200 The second absorbing layer 400 is formed on the upper part of the airlaid layer 300 to constitute a multi-layered absorbing layer.

<Comparative Example>
