Latest Patents

One of Sonoda's latest patents is for an improved apparatus and method for compressing a cylindrical blank into a tampon. This invention results in a tampon that is dimensionally stable and features a domed insertion end. The process involves radially compressing a cylindrical blank and introducing it into a cylindrical axial compression chamber. The blank undergoes extreme axial overcompression, and the closed insertion end of the chamber has a bore formed through it. This bore is generally coaxial and is designed to accept a reciprocating ejection ram. When the ram is in its first position, it and the insertion end wall of the chamber create a smooth doming surface. The bore's periphery is smaller in diameter than the chamber, allowing the ram to move freely and eject the tampon without interference.
