Abstract
A method of making a container (2, 30) having a separable inner lining (6) and outer shell (4) comprises the steps of: forming an outer shell; pre-forming a flexible lining, at least a part of the lining conforming to a complete internal shape of the shell; inserting the preformed 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 to an internal surface (8) of the shell; conforming the second part to an external surface of the shell; and attaching to the lining around said rim a sealing layer covering the opening, and the adhesion between the lining and the internal surface of the shell being such that the lining is peelable from the shell while remaining intact.
Claims26
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 shell being made from a paperboard or plastics material;
- pre-forming a flexible 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 an opening of the shell;
- adhering the first part of the lining to an internal surface of the shell;
- and
- conforming the second part of the lining to an external surface of the shell,
- wherein the adhesion between the lining and the internal surface of the shell is such that the lining can subsequently be peeled away 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.

A container having a separable inner lining and outer shell, wherein the container comprises:
- an outer shell made from a paperboard or plastics material;
- and
- an inner lining, the lining comprising a pre-formed flexible lining of a thin sheet of barrier material, a first part of the lining conforming to a complete internal shape of the shell and being adhered to an internal surface of the shell by a layer of adhesive, and a second part of the lining being in contact with an external surface of the shell,
- wherein the adhesive adhering the first part of the lining to 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, such that the inner lining and outer shell of the container are fully separated.
