## Abstract

A sanitary napkin that includes an elongate liquid-absorbent main pad body shaped to fit between a woman's thighs, an upper cover to promote flow to the body, a bottom cover to prevent flow out the bottom of the body, a vertical raised elongate pad section extending upwardly to an upper convex arcuate edge to extend between the labia of a woman but not into the woman's vagina, and wicking material extending from the raised elongate pad section to the main pad body to promote flow from the raised section to the main pad body.

## Claims

### Claim 1

A sanitary napkin comprising:
(a) an elongate liquid-absorbent main pad body comprising:
(i) a longitudinal axis,
(ii) a transverse axis with a transverse width adapted for placement between a woman's thighs without folding,
(iii) a top surface, and
(iv) a bottom surface,
(b) first cover means covering the top surface of the main pad body to promote transfer of liquid coming into contact with said first cover means means to the main pad body,
(c) second cover means on bottom surface of the main pad body to prevent transfer of liquid out the bottom surface of the main pad body,
(d) a raised elongate pad section attached to the main pad body and aligned along the longitudinal axis of the main pad body, said pad section comprising:
(i) an upper convex arcuate edge, and
(ii) a height above the top surface of the main pad body sufficiently high to extend between the labia of a woman, when said top surface is held against the labia, but sufficiently low so as not to extend into the woman's vagina, and
(e) wicking means extending from the raised elongate pad section to the main pad body to promote liquid flow from the raised elongate pad section to the main pad body comprising:
(i) a sheet body having a vertical lateral cross-sectional shape of an inverted "T",
(ii) an elongate vertical section of the sheet body extending upwardly centrally into the raised elongate pad section from a proximately centrally located line extending longitudinally within the main pad body, and
(iii) an elongate horizontal section of the sheet body extending laterally outwardly from a lower end of said vertical section proximately centrally located within the main pad body.

### Claim 2 (depends on 1)

The sanitary napkin of claim 1 wherein the upper surface of the main pad body and an outer surface of the raised elongate pad section is treated with a hydrophobic oil.
