Abstract
An article 1 comprises a hydrophilic foam layer 3; a reservoir cover 5 in contact with a first main surface of the hydrophilic foam layer 3, the reservoir cover 5 enclosing a reservoir cavity 7 together with the first main surface of the hydrophilic foam layer 3, the reservoir cavity 7 being for containing a fluid; and a hydrophobic foam layer 9 formed over the first main surface of the hydrophilic foam layer 3 and the reservoir cover 5. Fluid can be dispensed from the reservoir cavity 7 through a lower surface of the hydrophilic foam layer 3 by pressing on the hydrophobic foam layer 9 so that the reservoir cover 5 is compressed.

An article comprising:
- a hydrophilic foam layer;
- a reservoir cover in contact with a first main surface of the hydrophilic foam layer, the reservoir cover enclosing a reservoir cavity together with the first main surface of the hydrophilic foam layer, the reservoir cavity being for containing a fluid;
- and
- a hydrophobic foam layer formed over the first main surface of the hydrophilic foam layer and the reservoir cover.
A method of forming an article, the method comprising:
- positioning a reservoir cover in contact with a first main surface of a hydrophilic foam layer, so that the reservoir cover encloses a reservoir cavity together with the first main surface of the hydrophilic foam layer, the reservoir cavity being for containing a fluid;
- and
- forming a hydrophobic foam layer over the first main surface of the hydrophilic foam layer and the reservoir cover;
- wherein the method further comprises pressing the reservoir cover towards the first main surface of the hydrophilic foam layer when the hydrophobic foam layer is formed over the first main surface of the hydrophilic foam layer and the reservoir cover.
