ABSTRACT:
A packaging for fluid product such as a cream or a paste, has a flexible tube (1) provided with a dispensing neck (11), and a convenience closure system (2), including an annular base (20) fixed to the tube (1) on the neck side (11), and a top (21) mobile relative to the base (20). The neck (11) is formed by the wall (10) of the tube which converges towards the main axis (X) of the tube in the direction of the opening (100) with a relatively large radius with respect to its circumference, and the base (20) is engaged in the opening (100) of the tube, and causes the neck (11) to be radially stretched, and is locked relative to the opening along the main axis (X).
