<p>A heating pad comprises an inner pouch (1) and an outer cover (2). The pouch (1) is formed from two sheets heat sealed together at their edges to enclose a heat retaining liquid with granules of ground up polyurethane foam material. The granules tend to act as heat stores so that when the liquid is heated the heating pad will give off warmth over a substantial period of time. The pouch (1) can readily be warmed by heating within a microwave oven, whereupon the relatively cool edge (7) of the pouch can be gripped to insert the pouch into the container (2) which is formed from a textile material with quilting lines (8). A connecting strip (9) will co-operate with a portion of a flap (10) so that the outer cover can be closed to protect the pouch (1).</p> |
