摘要：A fitment to be attached to an apertured wall of a container or the like isinitially formed (as by plastic molding) with a thin cylindrical plastic molding) with a thincylindrical wall dimensioned to fit inside the aperture in the container. A flange is formedon the exterior of the cylindrical wall to fit against the exterior of the container wall,surrounding the aperture therein. Preferably the flange slants downward- outward. Acurling tool is forced against the end of cylindrical wall, curling it outward-upward to fittightly against the interior of the container wall opposite the flange, thereby crimpingthe fitment to the container. Curling of the cylindrical wall may be performed eitherbefore or after the fitment is installed on the carton. The fitment is formed to be closedby a cap and preferably to engage the cap in a tamper-evident manner. In a preferredform of the invention the cap and fitment are initially molded as a unitary member.
