A container/applicator in the assembled state, closed and filled with contents such as a cosmetic product, specifically a mascara, an eye-liner product or a lip-gloss product, having a generally elongate cylindrical shape along its axis and which comprises as means: - a reservoir for receiving contents, having a peripheral axial wall, a distal end closed by a bottom and an open proximal end with a proximal free edge, - a removable closure cap, having a peripheral axial skirt and a top wall, and an applicator/rod, arranged so that the cap and the applicator/rod form a unitary cap/applicator/rod (3+4), - a casing formed by a peripheral axial wall, having a distal end and an open proximal end, the reservoir and the casing having a common axial length of the reservoir and the casing, - an annular squeegee having an open distal edge forming a smaller opening and an open proximal edge forming a larger opening, - interface means comprising means for fixed rigid combination of the reservoir and the casing, means for removable rigid combination of the cap/applicator/rod (3+4) and the remaining portion of the container/applicator, and sealing means, characterised in that: - the squeegee is a part separate from the casing and is housed completely in the casing, - the squeegee has a proximal portion similar to a centrifugal protruding flange and a distal portion similar to a truncated cone or a spherical segment, - the squeegee is held by means for fixed rigid combination of the squeegee with the reservoir and the casing, - the casing has an open distal end, and a transverse step forming an inner shoulder, - the configuration of the casing is suited so that, during the manufacture of the container/applicator, on the one hand, the squeegee can be inserted, starting with its proximal edge, into the open distal end of the casing, then guided to slide axially into the casing in the proximal direction, and on the other hand, the reservoir filled with contents can be inserted, starting with its proximal edge, into the open distal end of the casing and then guided to slide axially into the casing in the proximal direction, - the proximal edge of the flange of the squeegee is adjacent to the inner shoulder, - the proximal edge of the reservoir is adjacent to the distal edge of the flange, - the flange is in peripheral contact with the inner face of smaller diameter of the casing, - the proximal end of the reservoir is housed completely in the casing and matches the inner face of smaller diameter of the casing, - the distal portion of the squeegee and the proximal end of the reservoir are in peripheral contact. - a reservoir for receiving contents, having a peripheral axial wall, a distal end closed by a bottom and an open proximal end with a proximal free edge, - a removable closure cap, having a peripheral axial skirt and a top wall, and an applicator/rod, arranged so that the cap and the applicator/rod form a unitary cap/applicator/rod (3+4), - a casing formed by a peripheral axial wall, having a distal end and an open proximal end, the reservoir and the casing having a common axial length of the reservoir and the casing, - an annular squeegee having an open distal edge forming a smaller opening and an open proximal edge forming a larger opening, - interface means comprising means for fixed rigid combination of the reservoir and the casing, means for removable rigid combination of the cap/applicator/rod (3+4) and the remaining portion of the container/applicator, and sealing means, - the squeegee is a part separate from the casing and is housed completely in the casing, - the squeegee has a proximal portion similar to a centrifugal protruding flange and a distal portion similar to a truncated cone or a spherical segment, - the squeegee is held by means for fixed rigid combination of the squeegee with the reservoir and the casing, - the casing has an open distal end, and a transverse step forming an inner shoulder, - the configuration of the casing is suited so that, during the manufacture of the container/applicator, on the one hand, the squeegee can be inserted, starting with its proximal edge, into the open distal end of the casing, then guided to slide axially into the casing in the proximal direction, and on the other hand, the reservoir filled with contents can be inserted, starting with its proximal edge, into the open distal end of the casing and then guided to slide axially into the casing in the proximal direction, - the proximal edge of the flange of the squeegee is adjacent to the inner shoulder, - the proximal edge of the reservoir is adjacent to the distal edge of the flange, - the flange is in peripheral contact with the inner face of smaller diameter of the casing, - the proximal end of the reservoir is housed completely in the casing and matches the inner face of smaller diameter of the casing, - the distal portion of the squeegee and the proximal end of the reservoir are in peripheral contact.
