A container that includes a substantially rigid body having a neck defining an opening providing access to the body cavity, and a bag positioned in the interior of the body. The bag is formed of thermoplastic material and has a neck from which there radially extends a flange which rests on the body and which defines a hole for providing access to the cavity of the bag and for sealedly housing the body of a hermetic pump (P) operable manually to withdraw the fluid substance (F) from the bag and feed it to the outside through its dispensing stem (S). The bag is formed by hot blow-moulding a preform positioned directly on the inside of the container. The preform surface presents at least externally a plurality of microspheres which roughen its surface.
