Abstract
A support device for a computer mouse (mouse pad) comprises, extending over the lower foil made of foam material, at least one thin, colored liquid layer which is enclosed between two foils welded together along the edge in a liquid-tight manner and is visible through the transparent foil or foils. The liquid occupies the available cavity only incompletely and it spreads out in puddle-like patterns to define void spaces which change continuously due to the actuation of the mouse, thereby providing the mouse pad with an optically interesting appearance.
Claims3
A method of making a support device for a computer mouse comprising the steps of:
- laminating a carrier layer over a lower foil;
- positioning the thus formed laminate such that the carrier layer faces upwardly;
- applying a liquid to the carrier layer without using confining means to confine the liquid such that the liquid remains on the carrier layer after application thereof;
- and then
- welding a transparent upper foil to the carrier layer along a continuous liquid-tight welding seam to define the periphery of a sealed cavity within which the liquid is captured, thereby creating a support device for a computer mouse having a transparent upper foil on which the computer mouse is manipulated and a liquid layer in the support device viewable through the transparent upper foil.
