A device for dispensing, by a manually operable pump, fluid substances contained in a deformable bag housed in a rigid container. The bag includes a mouth with a projecting flange with which the pump engages in coupling to the flange, and which causes the bag to be extracted from the container when the pump is separated from the container after the bag has been emptied.

1. A device for containing fluid substances under airtight conditions and dispensing them, comprising: a rigid container having a neck defining an aperture providing access to a container cavity,a manually operable pump having a body, a ring cap, and a dip tube,a bag made of thermoplastic material housed in the container and itself having a neck from which there radially extends a flange which rests on the free edge of the neck of the container and defines a hole for providing access to the cavity of the bag and for housing the body of the manually operable pump for withdrawing fluid substance from the bag and feeding it to the outside through the pump dispensing stem, the body of the pump being pressed to form a seal on said flange of the bag by the ring cap presenting elements for engaging corresponding elements provided on the neck of the container, passages being provided for air entry from the outside of the container into the space existing between the inner surface of the container and the outer surface of the bag housed therein,wherein at least a portion of said bag flange projects radially beyond the outer lateral surface of the neck of the container at least in proximity to the free edge of the neck, from the inner surface of said ring cap there extending at least one profiled element which is positioned beyond the free edge of said bag flange, to retain the flange when the device is in its use position and to rest on that surface of said flange facing the container, to interfere with said flange surface and cause the bag to be extracted from the container together with the pump when the ring cap is disconnected and removed from the container when the bag assumes a squashed form against and towards the pump dip tube after the fluid substance has already been totally dispensed by the pump,wherein said passages for air entry from the outside of the container into the space existing between the inner surface of the container and the outer surface of the bag housed therein consist of recesses provided in the outer surface of the bag neck and in the lower surface of the radial edge projecting therefrom, said recesses being bounded by longitudinal ribs projecting from the outer surface of the neck of the bag and respectively by ribs projecting radially from the surface of the bag flange. 2. A device for containing fluid substances under airtight conditions and dispensing them, comprising: a rigid container having a neck defining an aperture providing access to a container cavity,a manually operable pump having a body, a ring cap, and a dip tube,a bag made of thermoplastic material housed in the container and itself having a neck from which there radially extends a flange which rests on the free edge of the neck of the container and defines a hole for providing access to the cavity of the bag and for housing the body of the manually operable pump for withdrawing fluid substance from the bag and feeding it to the outside through the pump dispensing stem, the body of the pump being pressed to form a seal on said flange of the bag by the ring cap presenting elements for engaging corresponding elements provided on the neck of the container, passages being provided for air entry from the outside of the container into the space existing between the inner surface of the container and the outer surface of the bag housed therein,wherein at least a portion of said bag flange projects radially beyond the outer lateral surface of the neck of the container at least in proximity to the free edge of the neck, from the inner surface of said ring cap there extending at least one profiled element which is positioned beyond the free edge of said bag flange, to retain the flange when the device is in its use position and to rest on that surface of said flange facing the container, to interfere with said flange surface and cause the bag to be extracted from the container together with the pump when the ring cap is disconnected and removed from the container when the bag assumes a squashed form against and towards the pump dip tube after the fluid substance has already been totally dispensed by the pump,wherein the profiled element projecting from the inner surface of said ring cap consists of at least one continuous annular rib or a succession of annular rib segments which define at least one recess or annular groove into which the free edge of the flange projecting from the neck of the bag is inserted and retained, and said passages for air entry from the outside of the container into the space existing between the inner surface of the container and the outer surface of the bag housed therein consist of recesses provided in the outer surface of the bag neck and in the lower surface of the radial edge projecting therefrom, said recesses being bounded by longitudinal ribs projecting from the outer surface of the neck of the bag and respectively by ribs projecting radially from the surface of the bag flange. 3. A device for containing fluid substances under airtight conditions and dispensing them, comprising: a rigid container having a neck defining an aperture providing access to a container cavity,a manually operable pump having a body, a ring cap, and a dip tube,a bag made of thermoplastic material housed in the container and itself having a neck from which there radially extends a flange which rests on the free edge of the neck of the container and defines a hole for providing access to the cavity of the bag and for housing the body of the manually operable pump for withdrawing fluid substance from the bag and feeding it to the outside through the pump dispensing stem, the body of the pump being pressed to form a seal on said flange of the bag by the ring cap presenting elements for engaging corresponding elements provided on the neck of the container, passages being provided for air entry from the outside of the container into the space existing between the inner surface of the container and the outer surface of the bag housed therein,wherein at least a portion of said bag flange projects radially beyond the outer lateral surface of the neck of the container at least in proximity to the free edge of the neck, from the inner surface of said ring cap there extending at least one profiled element which is positioned beyond the free edge of said bag flange, to retain the flange when the device is in its use position and to rest on that surface of said flange facing the container, to interfere with said flange surface and cause the bag to be extracted from the container together with the pump when the ring cap is disconnected and removed from the container when the bag assumes a squashed form against and towards the pump dip tube after the fluid substance has already been totally dispensed by the pump,wherein the profiled element projecting from the inner surface of said ring cap consists of the inner end of at least one thread or rib engaging a corresponding thread or rib projecting from the neck of the container, this end of the ring cap thread being positioned between said flange and the rigid container, at least a peripheral portion of said flange being interrupted by at least one aperture to enable at least one thread projecting from the ring cap and engaging the corresponding thread projecting from the neck of the container to pass while mounting the ring cap on the container neck, and said passages for air entry from the outside of the container into the space existing between the inner surface of the container and the outer surface of the bag housed therein consist of recesses provided in the outer surface of the bag neck and in the lower surface of the radial edge projecting therefrom, said recesses being bounded by longitudinal ribs projecting from the outer surface of the neck of the bag and respectively by ribs projecting radially from the surface of the bag flange.
