ABSTRACT:
An edge seal for articles such as goggles and earphones comprises two layers of foam of a thermo-formable material between which there is located a heating body whose ends terminate in terminals for connection to a current source so as to heat the foam to its thermo-forming temperature while e.g. the goggles are held tightly on the head of a user by an elastic strap. This enables the seal to be moulded to the shape of the user's face.
