  • Patent number: 6846443
    Abstract: A tubular dispensing container has a head whose shoulder is joined to a tubular body. The head and shoulder can be thin because they are provided with a plurality of ribs that extend axially from the neck to the lower end of the shoulder and rigidify the head. A head for a tubular dispensing container is provided having the above-mentioned ribs. Apparatus for forming the head has male or female tooling with axially grooves formed therein to form the ribs on the inside or outside surface of the head. Methods involve flowing moldable material along the grooves to provide the lower end of the shoulder of the head with enough moldable material at elevated temperature and pressure to form a good bond of the shoulder with the tubular body.
