ABSTRACT:
A tampon-applicator assembly of reduced length is provided consisting of a cylindrical outer tube and a cylindrical inner tube snuggly nested coaxially within said outer tube. The inner tube is provided with a plurality of radially spaced ribs extending longitudinally along the inside surface thereof, the ribs terminating in bearing surfaces. A tampon is coaxially enclosed within the inner tube. A gripping portion is affixed to the distal end of the inner tube and extends out of the distal end of the outer tube. The gripping portion is provided for gripping the inner tube and reciprocating the same almost completely out of the distal end of the outer tube. At least one restraining element is provided in the distal end of the outer tube for restraining the tampon from reciprocating with the inner tube. In operation, the inner tube is reciprocated in a distal direction and the tampon is transferred from the inner tube to the outer tube. To insert the tampon, the inner tube is then reciprocated in the proximal direction and the ribs will bear against the distal end of the tampon and expel the same from the outer tube.
