Abstract

A sanitary napkin having a main body including at least three superposed functional layers, namely a fluid permeable body facing layer, an absorbent layer and a liquid impermeable undergarment facing layer. The sanitary napkin has flaps adapted to be folded around the edges of an undergarment of a wearer. The flaps are physically associated with respective longitudinal sides of the main body and are characterized by a rigidity sufficient to cause the longitudinal sides to fold upwardly when the flaps are parted to receive between them the crotch portion of the undergarment of the user. The upwardly folded longitudinal sides form upstanding barriers to limit the likelihood of failure as a result of side leakage.

Claims (15)

1. A sanitary napkin for placement in a crotch portion of an undergarment, said sanitary napkin comprising:
i) a main body having a pair of opposite longitudinal sides and a pair of opposite transverse sides, said main body including;
ii) a fluid permeable body facing layer;
iii) an absorbent layer underneath said fluid permeable body facing layer;
iv) a liquid impermeable undergarment facing layer underneath said absorbent layer, v) a flap affixed to a longitudinal side of said main body in a cantilever arrangement, said flap having a first position and a second position, said first position said flap acquiring a more acute angular relationship to said liquid impermeable undergarment facing layer than in said second position; said flap having a rigidity sufficient to cause the longitudinal side to fold upwardly when said flap is in said second position.
2. A sanitary napkin as defined in claim 1, wherein said flap is physically associated with the longitudinal side in a cantilever arrangement.
3. A sanitary napkin as defined in claim 2, comprising a flap physically associated with each longitudinal side of said main body.
4. A sanitary napkin as defined in claim 3, wherein each flap has a proximal end portion attached to a respective longitudinal side of said main body and a distal end portion remote from said proximal end, each flap further including an inner face oriented toward said main body and an outer face oriented away from said main body, a portion of said outer face adjacent said proximal end portion being attached to the respective longitudinal side of said main body.
5. A sanitary napkin as defined in claim 4, wherein said outer face is attached to said liquid impermeable undergarment facing layer.
6. A sanitary napkin as defined in claim 5, wherein said outer face is attached to said liquid impermeable undergarment facing layer by a method selected in the group consisting of adhesive bonding, heat-bonding, ultrasonic bonding, radio frequency bonding, mechanical crimping and combinations thereof.
7. A sanitary napkin as defined in claim 4, wherein said proximal end portion forms a loop that receives the respective longitudinal side of said main body.
8. A sanitary napkin as defined in claim 7, wherein said loop is retained to the respective longitudinal side of said main body at two spaced apart locations.
9. A sanitary napkin as defined in claim 8, wherein said loop is retained at said body facing layer and at said liquid impermeable undergarment facing layer.
10. A sanitary napkin as defined in claim 4, wherein the distal end portions of said flaps are retained to one another by a frangible bond.
11. A sanitary napkin as defined in claim 3, wherein when each flap is in said second position and the crotch portion of the undergarment is placed between the flaps, each longitudinal side of said main body is operative to urge the respective flap toward the crotch portion of the undergarment and cause engagement of each flap with the crotch portion of the undergarment.
12. A sanitary napkin as defined in claim 11, wherein each flap includes polymeric foam material.
13. A sanitary napkin as defined in claim 11, wherein each flap includes at least one embossed area enhancing a rigidity of the tab.
14. A sanitary napkin as defined in claim 1, wherein said absorbent layer includes a plurality of superposed layers.
15. A sanitary napkin as defined in claim 3, wherein said fluid permeable body facing layer and said liquid impermeable undergarment facing layer are united to one another to form a flange seal, each longitudinal side of said main body including a portion of said flange seal.
