Container and method for making and filling the same

1. A method of making a container having a separable inner lining and outer shell, the method comprising the steps of:

forming an outer shell of the container, the outer shell having a base, a sidewall and a rim surrounding an opening of the shell, the shell being made from a paperboard or plastics material;

pre-forming a flexible, non self-supporting lining from a thin sheet of barrier material, at least a part of the lining conforming to a complete internal shape of the shell;

inserting the pre-formed lining into the shell so that a first part of the lining is within the shell and a second part of the lining protrudes from the opening of the shell;

adhering the first part of the lining to an internal surface of the shell;

conforming the second part of the lining to an external surface of the shell; and

attaching a sealing layer to the lining around said rim so that the sealing layer covers the opening, the sealing layer being made from a flexible sheet of barrier material,

wherein the sealing layer is peelable from the lining such that the lining remains intact, and wherein the adhesion between the lining and the internal surface of the shell is such that the lining is peelable from the shell, so that the lining remains intact and no lining remains on the shell, to fully separate the inner lining and outer shell of the container.

2. A method as claimed in claim 1 , wherein the sealing layer is made from a sheet of plastics material or a sheet of metal foil.

3. A method as claimed in claim 1 , wherein the sealing layer is adhered to the lining using an adhesive or is heat welded to the lining.

4. A method as claimed in claim 1 , wherein the method further comprises, once the lining has been inserted into the shell, the step of folding the second part of the lining over the rim of the opening such that the second part of the lining is adjacent a region of the external surface of the shell.

5. A method as claimed in claim 1 , wherein the step of conforming the second part of the lining to the external surface of the shell around the opening comprises heating the second part of the lining such that the second part of the lining shrinks around the outside of the shell.

6. A method as claimed in claim 1 , wherein the method further comprises applying an adhesive to a region of the external surface of the shell around the opening, so that the second part of the lining is adhered to the shell in this region.

7. A method as claimed in claim 1 , wherein the method further comprises forming perforations in a portion of the second part of the lining.

8. A method as claimed in claim 1 , wherein the outer shell is substantially conical or frustoconical.

9. A method as claimed in claim 1 , wherein the outer shell is a non-laminated paper cup.

10. A method as claimed in claim 1 , wherein the outer shell is cylindrical.

11. A method as claimed in claim 1 , wherein the lining is made from a plastics material.

12. A method as claimed in claim 1 , wherein after inserting the pre-formed lining into the shell the lining is in contact with the internal surface of the shell over the complete area of the internal surface of the shell.
