Abstract
An absorbent feminine hygiene article has an external absorbent pad for disposition against the labia majora of a user, and a nonabsorbent flexible sheath for extending into the vagina. The sheath intercepts body fluid in the vagina and directs it to the external pad. A conducting layer conducts fluid so intercepted by the sheath to an absorbing surface on the interior of the external pad, the interior absorbing surface being displaced from the user's body by a primary mass of an absorbent layer.
Claims17
A method of fabricating an absorbent feminine hygiene article, said feminine hygiene article comprising an external pad having a length, a width and a predetermined outer perimeter and shape, a soft flexible film baffle, and a soft flexible film sheath adapted to extend vertically from said external pad a distance sufficient to permit insertion of at least a portion of said sheath into a user's vagina when said external pad is placed against the user's labia majora, said method comprising the steps of:
- (a) selecting a soft and flexible film material suitable for contact with female genitalia, and impervious to body fluid;
- (b) cutting, from said film material, a pair of film blanks, each said blank being shaped such that, when said blanks are joined together, the combination thereof can comprise said predetermined outer perimeter and shape, each said blank comprising (i) a perimeter edge portion extending from a first point to a second point along a first perimeter path describing substantially half of said outer perimeter of said external pad, and (ii) a joinder edge portion adapted to be joined with the other said blank of said pair, said joinder edge portion extending between said first and second points along a second path, different from said first path, said second path, at an intermediate locus, extending away from said perimeter edge portion to thereby describe elements of said sheath;
- (c) joining said joinder edge portions of said blanks;
- (d) bending said joined blanks to create first and second generally parallel opposed major surfaces thereof, thereby creating a baffle corresponding to said predetermined outer perimeter and shape, said film sheath comprising an extension of said baffle on said second major surface and wherein said first major surface is disposed toward the user;
- and
- (e) joining an absorbent layer to said first major surface of said baffle to form said article.
A method of fabricating an absorbent article, said article comprising a pad having a length, a width and a predetermined outer perimeter and shape, a soft flexible film baffle, and a soft flexible film sheath adapted to extend outwardly from said pad, said method comprising the steps of:
- (a) cutting a pair of film blanks, from a soft and flexible film material, each of said blanks being shaped such that, when said blanks are joined together, the combination thereof can comprise said predetermined outer perimeter and shape, each of said blanks comprising a perimeter edge portion describing substantially half of said outer perimeter of said external pad and a joinder edge portion adapted to be joined with the other said blank of said pair, said joinder edge portion extending away from said perimeter edge portion to thereby describe elements of said sheath;
- (b) joining said joinder edge portions of said blanks;
- (c) bending said joined blanks to create first and second generally parallel opposed major surfaces thereof, thereby creating a baffle corresponding to said predetermined outer perimeter and shape, said film sheath comprising an extension of said baffle on said second major surface;
- and
- (d) joining an absorbent layer to said first major surface of said baffle to form said article.
A method of manufacturing an absorbent feminine article having a cover, an absorbent and a baffle, wherein said baffle includes a flexible sheath adapted to extend outwardly from said baffle, said method comprising the steps of:
- (a) cutting a pair of blanks from a material that is liquid-impermeable and acceptable for contacting a user's vagina, said blanks having a perimeter edge portion which defines about half of an outer perimeter of a pad portion and a joinder edge portion which includes a sheath portion;
- (b) placing said pair of blanks in a face-to-face relationship and bonding said joinder edge portions on said blanks to each other thereby forming a bond line;
- (c) spacing apart said pad portions to form a single layer having a first and second opposing sides, thereby creating a baffle and a sheath extending from said baffle on said second side;
- and
- (d) securing said absorbent layer to said first side to form said article.
