发明名称 Lubricated tampon having invertible flaps for facilitated insertion and removal
摘要 A tampon including an absorption body enclosed in a cover. The tampon has an insertion end and a withdrawal end and further includes at least one withdrawal string. The cover includes a plurality of first invertible flaps or a plurality of second invertible flaps, or a combination thereof. Each first invertible flap is constituted by a portion of the cover and is arranged to be moved between a first initial position and a first inverted position during withdrawal of the tampon out of the vagina of a user so as to aid the withdrawal. Each second invertible flap is constituted by a portion of the cover and is arranged to be moved between a second initial position and a second inverted position during insertion of the tampon into the vagina of a user so as to aid the insertion.

主权项 1. A tampon comprising: an elongated absorption body at least partly enclosed in a liquid permeable cover, an insertion end, a withdrawal end, and at least one withdrawal string extending from said withdrawal end, wherein said liquid permeable cover comprises a plurality of first invertible flaps or a plurality of second invertible flaps or a combination thereof, wherein at least one first invertible flap of said plurality of first invertible flaps is constituted by a portion of said cover and comprises a first inner surface and an opposite first outer surface, said at least one first invertible flap is partly detachable from the remainder of said cover by a first slit system provided in said cover, is connected with the remainder of said cover via a first fold line, and is delimited by said first fold line and said first slit system, wherein said first fold line extends along a line between a first start point and a first end point of said first slit system, wherein said first slit system comprises at least one slit and extends along a first curve starting from said first start point and ending in said first end point, said first curve bulging away from said first fold line towards said withdrawal end, wherein said first slit system and said first fold line are arranged such that said at least one first invertible flap is movable between a first initial position and a first inverted position during withdrawal of said tampon out of the vagina of a user so as to aid said withdrawal, by being folded around said first fold line, and wherein said at least one first invertible flap is positioned in said first initial position before use of said tampon, and said first inner surface faces said absorption body in said first initial position and faces away from said absorption body in said first inverted position, and wherein said at least one second invertible flap is constituted by a portion of said cover and comprises a second inner surface and an opposite second outer surface, said at least one second invertible flap is partly detached from the remainder of said cover by a second slit system provided in said cover, is connected with the remainder of said cover via a second fold line, and is delimited by said second fold line and said second slit system, wherein said second fold line extends along a line between a second start point and a second end point of said second slit system, wherein said second slit system comprises at least one slit and extends along a second curve starting from said second start point and ending in said second end point, said second curve bulging away from said second fold line towards said insertion end, wherein said second slit system and said second fold line are arranged such that said at least one second invertible flap is movable between a second initial position and a second inverted position during insertion of said tampon into the vagina of a user so as to aid said insertion by being folded around said second fold line, and wherein said at least one second invertible flap is positioned in said second initial position before use of said tampon, and said second inner surface faces said absorption body in said second initial position and faces away from said absorption body in said second inverted position.
