Abstract
A sanitary napkin for retention of vulvar discharge includes a shell that defines an interior space. The shell is flexible and liquid impermeable. A ridge, which defines a canal, extends from the front of the shell around a perimeter of an opening. An absorbent is positioned in the interior space and the canal. A pair of fasteners is coupled singly to and extends from opposing edges of the shell. A first improvement is the liquid impermeability of the front of the shell, wherein vulvar discharge is effectively retained within the interior space of the shell. A second improvement is the ridge that is positioned on the front. The shell is sealably positionable over the vulva of the user such that vulvar discharge is directed to the opening.
Claims13
A sanitary napkin comprising:
- a shell defining an interior space, said shell being flexible, said shell being liquid impermeable;
- an opening positioned in a front of said shell;
- a ridge integrally extending from said front of said shell around a perimeter of said opening defining a canal within said ridge, wherein said ridge is positioned on said shell such that said ridge is configured to sealably contact the skin of the user;
- an absorbent positioned in said interior space and extending into and occupying said canal;
- a pair of fasteners coupled singly to and extending from opposing edges of said shell, wherein said fasteners are positioned on said shell such that said fasteners are configured for coupling of said shell to an article of clothing, such that said opening is positioned proximate to the vulva of a user;
- and
- wherein said front of said shell is liquid impermeable such that vulvar discharge is effectively retained within said interior space of said shell, and wherein is said ridge is positioned on said front such that said shell is sealably positionable over the vulva of the user such that vulvar discharge is directed to said opening.
A sanitary napkin comprising:
- a shell defining an interior space, said shell being flexible, said shell being liquid impermeable, said shell comprising plastic;
- an opening positioned in a front of said shell, said opening being positioned substantially equally distant from opposing edges of said shell, said opening being positioned substantially equally distant from opposing ends of said shell, said opposing ends being arcuate;
- a ridge integrally extending from said front of said shell around a perimeter of said opening defining a canal within said ridge, wherein said ridge is positioned on said shell such that said ridge is configured to sealably contact the skin of the user, said ridge being arcuate;
- an absorbent positioned in said interior space and extending into and occupying said canal, said absorbent being coupled to said shell and said canal;
- a pair of fasteners coupled singly to and extending from said opposing edges of said shell, wherein said fasteners are positioned on said shell such that said fasteners are configured for coupling of said shell to an article of clothing, such that said opening is positioned proximate to the vulva of a user, said fasteners being positioned substantially equally distant from said opposing ends of said shell, said fasteners comprising tabs having a rear face, said rear face comprising adhesive, said tabs being substantially rectangularly shaped;
- a cover complimentary to said opening, said cover being coupled to said shell such that said cover extends over said opening, said cover being liquid permeable, wherein said cover is positioned over said opening such that said cover is positioned between said absorbent and the user, said cover comprising perforated plastic;
- and
- wherein said front of said shell is liquid impermeable such that vulvar discharge is effectively retained within said interior space of said shell, and wherein said ridge is positioned on said front such that said shell is sealably positionable over the vulva of the user such that vulvar discharge is directed to said opening.
