Abstract: A fluid reservoir comprising: a slide cylinder (11); a neck (12) that defines an outlet opening (13); an internal shoulder (14) that connects the slide cylinder (11) to the outlet opening (13), the internal shoulder (14) being provided with an annular groove (15) that extends in line with the slide cylinder (11), such that the internal shoulder (14) defines an annular collar (16) that connects the annular groove (15) to the outlet opening (13); and a follower piston (2) that is engaged to slide in leaktight manner in the slide cylinder (11), the piston (2) defining at least one sealing lip (21) that is received in the annular groove (15) when the reservoir is empty; the fluid reservoir being characterized in that the annular collar (16) is formed with at least one radial channel (17; 17′) that connects the annular groove (15) to the outlet opening (13) of the neck (11).
