• barrier materials molded in a massive way, but such materials are relatively expensive.
• the use of such barrier materials requires the use of the same barrier material or compatible material for the sheet forming the pocket, preferably by welding. This would result in a significant increase in the cost and complexity of manufacturing the overall device.
• patent document EP 0 354 137 describes a device for packaging and dispensing a fluid product comprising a sealed flexible bag placed in a rigid bottle and associated with a pump or a valve, this pocket having a cylindrical wall constituted a sheet wound in a cylinder whose one edge is sealingly attached to a flange forming a fixing ring to the bottle and the pump or the valve.
• This ring is made of a plastic material and its inner face may carry a barrier effect washer partially covering the inner face of the ring and this washer may be a metal-plastic complex comprising a metal film.
• This washer is welded to the face of the ring by a large face and retained at its base by a small annular bead of plastic.
• Such a washer does not form an effective barrier, because it does not cover the inner face of the ring under the bead of plastic holding its base.
• the invention improves the barrier effect of such a cover layer and provides an easy manufacturing device and an arrangement that easily adapts to the current flanges made of plastic.
• a device for packaging and dispensing a fluid product comprising a sealed flexible pouch placed in a rigid bottle and associated with a pump or a valve, this pouch having a cylindrical wall consisting of a wound sheet following a cylinder whose one edge is sealingly attached to a flange forming a fixing ring to the bottle and the pump or to the valve, this flange being made of a plastic material, the inner face of said flange carrying a covering sheet worn by the inner face of said flange, characterized in that the other edge of said sheet is sealingly attached to a second flange forming the bottom of the pocket, this second flange being made of a plastic material, and in that the internal face of said flanges carries a cover sheet completely covering the inner face of said flanges.
• the metal film of the cover sheet of each flange provides a reliable barrier at the entire inner face of each flange in contact with the packaged product contained in the pocket.
• said cover sheet comprises at least one film of the same plastic material as said flange and said metal film, its plastic film being turned towards the inner face of said flange.
• the cover sheet is then a multilayer sheet comprising at least one plastic film and a metal film.
• This plastic film being of the same plastic as the flange and facing the inner face of the flange, a welding attachment of the cover sheet and the flange can be performed particularly effectively.
• said sheet of the cylindrical wall is a multilayer sheet comprising at least one inner plastic film and a metal film
• said cover sheet comprises at least one film of the same plastic material as said inner film of said sheet of the cylindrical wall and said metal film, its plastic film being turned towards the inner face of said cylindrical wall.
• the cover sheet is then a multilayer sheet comprising at least one plastic film and a metal film. Since the plastics material of the inner film of the multilayer film of the cylindrical wall is identical to that constituting the film of the covering layer turned towards the internal face of the said cylindrical wall, a welded connection between this wall and the coated flange can be realized. in a particularly effective way.
• said metal film (s) is (are) aluminum.

• the flange comprising a solid disk or a ring having a raised edge forming a lateral annular surface, to which is fixed the edge of said sheet of the cylindrical wall, said cover sheet preferably also covers at least a portion of said lateral annular surface.
• This embodiment provides a total barrier at the entire inner face of the flange in contact with the packaged product contained in the pocket.
• said cover sheet is a multilayer sheet, its layers being made of polyethylene, polyethylene terephthalate, aluminum and polyethylene.
• the invention also relates to a method of manufacturing such a device, characterized in that said cover sheet is overmolded on the inner face of said flanges by the labeling method in the mold commonly called "IML".
• this process ensures a perfect positioning of the cover sheet and thus a perfect and complete overlap of the inner face of each flange.
