Abstract
The invention features a disposable absorbent article including a thermoplastic composition applied in a full coat layer (i.e. a layer with 100% coverage) as a discrete shape to either the top sheet or to a component of the absorbent core (i.e. core or core wrap). The discrete shape is strategically located to decrease the likelihood of leaks in the desired location. The thermoplastic composition serves as a leak barrier to prevent bodily fluids and solids (i.e. urine, stool, menstrual flow, wound seepage) from leaking from the absorbent core.
Claims20
A disposable absorbent article, comprising:
- a. a top sheet,
- b. a back sheet, and
- c. an absorbent core disposed between the top sheet and the back sheet,
- the top sheet, the back sheet, and the absorbent core forming a layered assembly held together with an attachment means, the disposable absorbent article further comprising a thermoplastic composition applied in a full coat layer as a discrete shape to the top sheet or to a component of the absorbent core and overlapping a portion of the absorbent core.
A method of forming a leak barrier on a disposable absorbent article comprising the steps of:
- a. applying a thermoplastic composition in a full coat layer of a discreet shape to the top sheet or to a component of the absorbent core, and
- b. joining the top sheet to the back sheet while inserting the absorbent core,
- such that the thermoplastic composition overlaps a portion of the absorbent core.
An absorbent core comprising:
- a. a core,
- b. a core wrap, and
- c. a thermoplastic composition,
- wherein the thermoplastic composition is applied in a full coat layer of a discreet shape to the core wrap, so as to directly overlap a portion of the core when wrapped around the core.
