## Abstract

The invention relates to a device for packaging and dispensing a fluid product, having a leaktight flexible pouch (1) placed in a rigid bottle (10) and associated with a pump or a valve (13), this pouch having a cylindrical wall consisting of a sheet (2) rolled into a cylinder, one edge of which is fixed in a leaktight fashion to a flange forming a ring for fastening to the bottle and to the pump or the valve, this flange (4) consisting of a plastic material, the other edge of the said sheet is fixed in a leaktight fashion to a second flange forming the bottom of the pouch, this second flange (3) consisting of a plastic material, these flanges (3, 4) having a solid disk or a ring having a raised edge (3A, 4A) forming an annular lateral surface, to which the edge of the said sheet (2) forming the wall of the pouch is fixed, the said sheet (2) of the cylindrical wall being a multilayer sheet having at least one inner film of plastic material. According to the invention, the inner face of the said flanges carries a covering sheet (20A, 20B) entirely covering the inner face of the said flanges and also covering at least a part of the said inner annular lateral surface for fastening the edge of the said sheet (2) forming the wall of the pouch, and the said covering sheet (20A, 20B) has at least one film of the same plastic material as the said inner film of the said sheet of the cylindrical wall and a metal film, its plastic material film facing toward the inner face of the said sheet (2) constituting the cylindrical wall.

## Claims

### Claim 1

Device for packaging and dispensing a fluid product comprising:
a leaktight flexible pouch placed in a rigid bottle; and
a dispensing element, where said dispensing element has a pump or a valve,
said pouch having a cylindrical wall formed from a multi-layer pouch sheet rolled into a cylinder, a first top pouch edge of said dispensing element is fixed in a leaktight fashion to a first flange forming a ring for fastening to the bottle and to the dispensing element,
said first flange formed from a plastic material, a second bottom pouch edge of said multi-layer pouch sheet being fixed in a leaktight fashion to a second flange forming the bottom of the pouch,
said second flange formed from a plastic material, said first and second flanges having a solid disk or a ring having a raised annular lateral surface, to which the bottom pouch edge of said multi-layer pouch sheet forming the wall of the pouch is fixed, said multi-layer pouch sheet of the cylindrical wall having at least one inner layer of plastic material,
wherein the inner faces of said first and second flanges each carry a multi-layer covering sheet entirely covering their inner faces and also covering at least a part of said inner annular lateral surface for fastening the first top and second bottom edges of said multi-layer pouch sheet forming the wall of the pouch, and
wherein said multi-layer covering sheet has at least one layer of the same plastic material as said inner layer of said multi-layer pouch sheet of the cylindrical wall, said multi-layer pouch sheet and said multi-layer covering sheet both having an outer layer of a metal, said plastic inner layer of said multi-layer covering sheet facing toward the inner face of said multi-layer pouch sheet.

### Claim 2 (depends on 1)

Device according to claim 1, wherein said multi-layer covering sheet has outer metal layer with said inner plastic layer being of the same plastic material as said flanges, wherein said plastic material inner layer of said multi-layer covering sheet facing inward towards said pouch.

### Claim 3 (depends on 1)

Device according to claim 1, wherein said metal layers are made of aluminum.

### Claim 4 (depends on 1)

Device according to claim 1, wherein said plastic material is polyethylene.

### Claim 5 (depends on 1)

Device according to claim 1, wherein said layers of either one of said multi-layer covering sheet or said multi layer pouch sheet are made of polyethylene, polyethylene terephthalate, aluminum and polyethylene.

### Claim 6 (depends on 1)

Device according to claim 1, wherein said multi-layer covering sheet is welded onto the inner face of said multi-layer pouch sheet.
