A device for packaging and dispensing a fluid product, the device comprising:
- a body which is hollow and provided with a bottom or a lower edge at a lower end of the body;
- a reservoir portion which comprises a container defining an internal volume of the reservoir and extending into an inside volume defined by the body, the container having a longitudinal axis and an opening at an axial upper end of tubular shape;
- a head which comprises a metering assembly of airless type and a stopper member closing off the opening, the metering assembly comprising a metering pump and a movable actuating portion to enable dispensing the fluid product;
- and
- an upper connector onto which the body is fixed in a locked configuration of the upper connector, the upper connector having a radial portion which extends radially outward, around a channel for the passage of the metering pump, to a tubular outer portion;
- wherein the device has an outer side wall extending around the longitudinal axis, from the lower end of the body to an annular upper edge of the tubular outer portion,
- wherein the device further comprises a retaining ring, which is:
- in contact with the body and mounted to be axially movable relative to the body in unlocked configuration of the upper connector;
- designed and arranged to lock axially together the reservoir portion and the head regardless of whether or not the upper connector is in the locked configuration;
- and
- engaged on engagement rims distributed over an outer face of the container and on the head, such that the head, the reservoir portion, and the retaining ring constitute a preassembled inner unit of the device, the retaining ring being covered by the outer side wall in an assembled state of the device, and wherein:
- the body comprises an upper attachment end which, in said assembled state and for the locking configuration, is axially engaged with an attachment area provided in the tubular outer portion, the attachment area and the upper attachment end forming a removable connection between the upper connector and the body, and in the locking configuration making it possible to keep the inner unit bearing axially against a lower inner face of the radial portion;
- and
- the upper connector is integrally secured to the upper attachment end by a locking action which takes place by a pivoting, about the longitudinal axis, of one among the upper connector and the body relative to the other.
