A fitment (26) to be attached to an apertured wall (21) of a container is initially formed (as by plastic molding) with a thin cylindrical wall (27) dimensioned to fit inside the aperture (22) in the container. A flange (28) is formed on 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. A curling tool is forced against the end of cylindrical wall, curling it outward-upward to fit tightly against the interior of the container wall opposite the flange, thereby crimping the fitment to the container. Curling of the cylindrical wall may be performed either before or after the fitment is installed on the carton. The fitment is formed to be closed by a cap (46) and preferably to engage the cap in a tamper-evident manner. In a preferred form of the invention the cap and fitment are initially molded as a unitary member. |
