Abstract
A dispenser of a product includes a body forming a lateral wall in a moulded plastic material with, at its upper end, an upper orifice, and at its lower end, a bottom including a circular lower orifice. The lateral wall includes an assembly of an inner jacket including an inner tubular part, of area cross-section Si and thickness Ec, and an outer body including an outer tubular part of area cross-section Se>Si and thickness Ei, said thicknesses Ec and Ei being taken typically below 2 mm, so as to be able to manufacture the dispenser by high throughput moulding and without dimensional distortion of the inner jacket and of the outer body of plastic material, and in such a way that the outer body is able to have a cross-section different from that of the inner jacket.
