Abstract

Abstract An improved tampon-inserter stick combination in which the socket disposed in the rear portion of a compressed tampon and adapted to frictionally receive a removable inserter stick is provided with a convex bumper at the base of the socket. The bumper acts as a stop to control the depth to which the leading end of the stick can be pushed into the socket and, by eliminating or minimizing the tapered configuration at the base as found in prior art sockets, assures that the frictional resistance between inserter stick and socket is substantially uniform for all products, while eliminating the possibility that the inserter stick might be pushed too far into the socket during packing, handling or insertion and make removal difficult. The improved socket structure thus insures easy removal of the inserter stick after the tampon has been positioned in the vagina by the user. A tool for forming the socket is also defined.
