Toxicity resistant tampon structure

A flow-controlling tampon, comprising

• a) a generally upright enlongated sheath structure having an open upper end and a closed lower end, said upper end sized to fit about the cervix,
• b) an inner, elongated, flow-control tube extending generally upright within said sheath, said tube having an upper open end to receive flow via said upper open end of the sheath, and said flow-control tube having lower opening means to pass flow from the tube into the lower interior of the sheath to gradually collect upwardly from said lower interior of the sheath, and about the control tube,
• c) there being moisture absorbent fill material in the lower interior of the sheath and extending about said tube,
• d) said sheath including a funnel-shaped upper portion defining said open upper end of the sheath, said funnel-shaped upper portion having a looping upper edge to fit about the cervix,
• e) and including a closure flap having hinge support within the sheath and proximate the uppermost extent of said tube, and a withdrawal string attached to said flap to urge the flap in tube-closing direction when the string is pulled downwardly, the flap normally extending within the sheath in a position wherein the flap does not obstruct flow in the tube.
