A tampon for feminine hygiene having an absorbent core and a cover disposed around the core which is permeable to body fluids, the cover being provided with flexible barrier strips which are spreadable from the tampon surface. The barrier strips serve to close the space between the tampon surface and the walls of the vaginal duct when the tampon is inserted, preventing leakage especially in the time just after insertion. The barrier strips may be of either hydrophilic or hydrophobic material. In the embodiment in which the barrier strips are hydrophilic, they serve as absorbent elements of the tampon in addition to the tampon core. In the embodiment in which the barrier strips are of a hydrophobic material, they direct menstrual fluids inwardly to the absorbent tampon core. In yet another embodiment, the barrier strips may be of a folded two-layer construction filled with an absorbent material.
A tampon for feminine hygiene comprising an absorbent core, a cover which is disposed around the core so as to define a tampon surface and is permeable to body fluids, the tampon being further provided with at least one flexible barrier strip disposed around the tampon surface laterally to a direction of insertion of the tampon, the at least one barrier strip having first and second edges, the first edge attached at the tampon surface the second edge being spaced apart from the first edge in the same direction as the direction of insertion of the tampon, the barrier strip being outwardly spreadable from the tampon surface at the second edge of thereof.
A rotationally symmetrical tampon for feminine hygiene comprising an absorbent core and a cover surrounding the core so as to define a tampon surface, the cover being provided with at least one barrier strip extending circumferentially around the tampon surface, the at least one barrier strip having first and second edges, the second edge being spaced apart from the first edge in the same direction as a direction of insertion of the tampon, the at least one barrier strip being radially outwardly spreadable from the tampon surface.
A substantially cylindrically-shaped tampon for feminine hygiene comprising an absorbent core and a cover surrounding the core, the cover being provided with at least one barrier strip disposed circumferentially around the core, the at least one barrier strip having first and second edges, the first edge of the at least one barrier strip being attached to the core of the tampon and the second edge of the at least one barrier strip being attached to the core of the tampon at spaced apart locations about the circumference thereof, the second edge being spaced apart from the first edge in the same direction as a direction of insertion of the tampon, the at least one barrier strip being outwardly spreadable from the core of the tampon at the second edge of thereof between the spaced apart attached locations to define bags, each bag having a bag opening between the cover and the at least barrier strip second edge for receiving menstrual fluids and solids.
