Abstract

A die-cut lid (20) for closing a container is disclosed; the lid being formed from a flexible composite sheet material (30).The lid comprises a functional area (70) bearing human-readable and/or machine-readable data with the lid comprising one or more rigidifying indentations (50) to promote flatness of the functional area in a resting state of the lid. The one or more rigidifying indentations are selected from the group of:i) one or more encircling indentations that border the functional area; and/orii) a planar indentation that encompasses the functional area.A lidded container (1) comprising such a die-cut lid and a method of forming a die-cut lid are also described.

First claim

The invention claimed is:

1. A method of forming a die-cut lid, comprising the steps of:
a) providing a flexible composite sheet material;
b) printing human-readable and/or machine-readable data on the flexible composite sheet material;
c) forming one or more rigidifying indentations to promote flatness of a functional area encompassing said human-readable and/or machine-readable data; and
subsequently at least partially flattening the one or more rigidifying indentations;
wherein after the step of forming one or more rigidifying indentations, the lid is sealed to a container; and
wherein the step of at least partially flattening the one or more rigidifying indentations takes place during the step of sealing the lid to the container.

2. The method of claim 1 , wherein at least a portion of the lid is additionally embossed.

3. The method of claim 1 , wherein the one or more rigidifying indentations are formed by stamping/pressing or rolling.

4. The method of forming a die-cut lid according to claim 1 , comprising the step of die-cutting the flexible composite sheet material to form the lid.

5. The method of claim 1 , wherein at least a portion of the lid is additionally embossed prior to the step of forming one or more rigidifying indentations.
