Fluid product dispensing and application assembly

A fluid dispenser comprising a dispenser member, a dispenser head, and a fluid reservoir that is connected in leaktight and removable manner to the dispenser member, the sealing between the dispenser member and the fluid reservoir being obtained by coaxially sliding leaktight radial contact that is interrupted when the fluid reservoir is disconnected from the dispenser member, such that the fluid reservoir is connected in leaktight manner to the dispenser member over a determined axial height range;

• wherein the dispenser member further comprises an outer covering element that is open at its bottom end for inserting the fluid reservoir that is provided with a stopper element secured to the fluid reservoir and that comes into abutting contact with the bottom end (512) of the outer cover so as to form a continuous outer cover;
• wherein the dispenser member includes an inlet tube the inside of which forms an inlet duct and the outside of which forms an annular bearing surface that is in leaktight sliding contact in a slide cylinder that is secured to the fluid reservoir, so as to define between them said coaxially sliding leaktight radial contact;
• and
• wherein the dispenser member includes a connection ring that forms the inlet tube and an external thread, the fluid reservoir including a connection ferrule that forms the slide cylinder and an internal thread for coming into engagement with the external thread of the connection ring.
