ABSTRACT:
The product dispenser (1) comprises a container (4) inside which is located a bag (2) made from a deformable plastic compound; a base (7) carrying the dispensing member (8) is mechanically held with respect to the container (4), a bottom end of the bag (2) being welded along a band (33). The bag (2) is formed from a sheath obtained by welding, along at least one longitudinal band (32), the longitudinal edges of a strip. The longitudinal band of weld (32) welds an inner face of a longitudinal edge of the strip, from which the bag (2) is formed, to the inner face of the other longitudinal edge of the strip situated on the same side of the strip as the previous face. The base (7) includes a weld surface (10), and the welded assembly of the two longitudinal edges of the strip is folded back against the outer surface of the sheath and welded in this position by the weld for welding the end of the bag (2) onto the weld surface (10) of the base.
