ABSTRACT:
The invention concerns the dispensing packagings for viscous, creamy or paste products, as well as a manufacturing method for these dispensing packagings. The body (6) of the packaging according to the invention, in substance tubular, comprises an interior envelope (8), apt for containing the product to be dispensed, and an exterior envelope (7) capable of yielding to the pressure and then to regain, in substance, its initial form. These two envelopes (7, 8) are coupled and united according to a line parallel, in substance to the axis of the body (6). The tubular body (6) thus formed is then welded, by one of its extremities, to a dispenser head (1), the other extremity being closed by a weld or placed on a base. The packaging according to the invention applies notably to cosmetic products, to health care products and to technical products.
