ABSORBENT ARTICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18198303 titled 'ABSORBENT ARTICLE
Simplified Explanation
- The patent application describes a disposable absorbent article, such as a diaper or sanitary napkin, that includes a topsheet, a backsheet, and an absorbent core structure. - The absorbent core structure consists of an upper nonwoven layer, a lower nonwoven layer, and an inner core layer. - The upper nonwoven layer is made of polymer fibers and has a basis weight (weight per unit area) of 35 to 85 grams per square meter (gsm). - The lower nonwoven layer is also made of polymer fibers and has a basis weight of 10 to gsm. - The inner core layer is located between the upper and lower nonwoven layers and is made up of 50% to 85% cellulosic fibers and 15% to 50% superabsorbent particles, by weight. - The absorbent core structure has an average density between 0.045 and 0.15 grams per cubic centimeter (g/cm). - The upper and lower nonwoven layers are sealed to contain the inner core layer within them, specifically at the left and right side regions.
Original Abstract Submitted
A disposable absorbent article having a topsheet, a backsheet, and an absorbent core structure disposed therebetween. The absorbent core structure includes an upper nonwoven layer comprising polymer fibers and having a basis weight of from about 35 to about 85 gsm; a lower nonwoven layer comprising polymer fibers and having a basis weight of from about 10 to about gsm; and an inner core layer disposed between the upper and lower nonwoven layers. The inner core layer comprises from about 50% to about 85% cellulosic fibers, by weight of the inner core layer, and from about 15% to about 50% superabsorbent particles, by weight of the inner core layer. The absorbent core structure has an average density of between about 0.045 g/cmand about 0.15 g/cm. The inner core layer is contained within the nonwoven layers by substantially sealing at least a left and right side region of the upper and lower nonwoven layers.
