Abstract
Abstract A reusable and microwavable hot insulated compress has a bottom laminate, a first pocket containing a gel, a middle laminate being positioned above the first pocket and including a top layer of insulative material, a second pocket being provided with a dead air space as additional insulation above the insulative material, and a top laminate being positioned above the second pocket. The bottom, middle and top laminates each have outer peripheral edges that are bonded together by a radio frequency (RF) heat-sealing step. A method is also disclosed for manufacturing the compress.
