Patent ID: 7808603

Claim:
A method of manufacturing a laminated article, the method comprising: providing a first substrate having a first major surface on which is located a plurality of upstanding wall structures, each wall structure defining a respective well having a base portion and a remote portion, the base portion being adhered to or integrally formed with the first substrate and the remote portion defining the only opening to the well; providing a portion of an adhesive material within at least one of the wells; providing a second substrate having a second major surface, at least one of the first or second substrates being flexible; bringing together the first substrate and the second substrate with the first major surface facing the second major surface at a nip region and applying pressure at the nip region to cause or promote adhesion of the adhesive material to the second major surface over a laminated area; providing a fluid material between the substrates at the nip region so as to trap the fluid material in a layer between the substrates in the laminated area, the fluid material which is outside the wall structures in the laminated area being isolated from the adhesive material and any fluid material within the wells; and causing relative movement between the nip region and the substrates while continuing to apply the fluid material so as progressively to increase the size of the laminated area containing the fluid material.
