Abstract

The invention is providing a flexibility stiff reinforcing member that will maintain the shape of a pad for absorption of human exudate, such as a feminine hygiene pad, during use. The flexibly stiff reinforcing member will return the pad to its desired shape, even after it has been deformed by movement of the wearer. In a particularly preferred form, the flexibly stiff reinforcing member is a flat strip of polyethylene that extends around the periphery of a feminine hygiene pad. In other embodiments, the resilient reinforcing member may only be present in the periphery of the center or crotch portion of the pad. The strength and flexibility required of the reinforcing member will vary depending on the pad stiffness prior to reinforcing of the pad and the use to which the pad is to be put. The reinforcing element is a flexibly stiff, resilient, substantially nonelastic material. The reinforcing element material may be deformed and then is springy and will return to its shape after deformation.

Claims

1. A device for absorption of human exudate comprising an absorbent, a liquid permeable cover and a liquid-impermeable baffle cooperating to enclose said absorbent, and reinforcing means for shaping said device to conform to the body of a user, said reinforcing means having a predetermined arcuate shape prior to being assembled thereby imparting a cup-like shape to said device.

2. A device for absorption of human exudate comprising an absorbent, a liquid permeable cover and a liquid-impermeable baffle cooperating to enclose said absorbent, and reinforcing means for shaping said device to conform to the body of a user, said reinforcing means being a non-apertured member having a predetermined arcuate shape prior to being assembled thereby imparting a cup-like shape to said device.

3. A device for absorption of human exudate comprising an absorbent, a liquid permeable cover and a liquid-impermeable baffle cooperating to enclose said absorbent, and a reinforcing member having three or more axially aligned openings formed therein with the end openings being smaller than the opening aligned therebetween.

4. A device for absorption of human exudate comprising an absorbent, a liquid permeable cover and a liquid-impermeable baffle cooperating to enclose said absorbent and reinforcing means for shaping said device to conform to the body of a user, said reinforcing means having a hollow tubular cross-section with semicircular shaped ends.

5. The device of claim 4 wherein said reinforcing means is arcuate in shape.

6. The device of claim 5 wherein said reinforcing means has a predetermined arcuate shape prior to being assembled thereby imparting a cup-like shape to said device.

7. A device for absorption of human exudate comprising an absorbent, a liquid permeable cover and a liquid-impermeable baffle cooperating to enclose said absorbent, and reinforcing means for shaping said device to conform to the body of a user, said reinforcing means being a relatively flat non-apertured member having at least one outwardly extending arm, said arm having a rounded end.

8. The device of claim 7 wherein said reinforcement member has at least two outwardly extending arms, each of said arms having a rounded end.

9. The device of claim 7 wherein said reinforcing member has at least three outwardly extending arms, each of said arms having a rounded end.

10. The device of claim 7 wherein said reinforcing member has at least four outwardly extending arms, each of said arms having a rounded end.
