Abstract
A tube head is provided which is designed to be associated with a skirt so as to form an internal volume of the tube. The tube head includes a body formed from plastics material, that includes a neck having an opening at a first end, through which opening a product is removed from the internal volume of the tube, and a shoulder which is joined to a second end of the neck opposite the first end. The tube head also includes an insert arranged so as to be in contact with said shoulder and forming a barrier between the body and the product contained in the internal volume. The insert includes a central portion and a peripheral region. The central portion forms a non-perforated disc sealing the neck, and the peripheral region being mounted so as to as to be in contact with a complementary planar surface of the body.
