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.
L'invention concerne un distributeur tubulaire qui comprend une tête dont l'épaulement est reliée au corps tubulaire. La tête et l'épaulement peuvent être étroits car ils possèdent plusieurs nervures s'étendant de façon axiale à partir du col jusqu'à l'extrémité inférieure de l'épaulement et renforçant la tête. Un moule mâle (52) forme l'intérieur de la tête, et renferme des rainures axiales (54) conçues de manière à former les nervures sur la surface intérieur de la tête, une fois que la tête a été moulée. Le corps tubulaire est positionné sur un mandrin mâle (56) aligné de façon axiale avec le moule femelle formant la tête.
