Liquid transfer device.

摘要

A device (2) provides liquid material for application to a surface. The device comprises in order at least a carrying substrate (4), frangible microcapsules (6) containing the liquid to be applied, a raised area around the microcapsules of a structurally rigid material (8), and a flexible, liquid permeable material (10) overlaying the microcapsules. Pressure on the liquid permeable material ruptures the microcapsules and enables the liquid to flow through the permeable material.
