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.
Claims8
A compress comprising:
- a first layer of fabric having a top surface;
- a first layer of adhesive spread on the top surface of the first layer of fabric;
- a first layer of plastic adhered to the top surface of the first layer of fabric by the first layer of adhesive;
- a gel contained in a pocket above the first layer of plastic;
- a second layer of plastic being positioned above the pocket containing the gel, said second layer of plastic having a top surface;
- a second layer of adhesive spread on the top surface of the second layer of plastic;
- a layer of insulative material adhered to the top surface of the second layer of plastic by the second layer of adhesive;
- sealed off pocket means for providing a dead air space as additional insulation above the layer of insulative material;
- a third layer of plastic positioned above the pocket means for providing the dead air space as additional insulation, said third layer of plastic having a top surface;
- a third layer of adhesive spread on the top surface of the third layer of plastic;
- and
- a second layer of fabric adhered to the top surface of the third layer of plastic by the third layer of adhesive.
A method of manufacturing a compress, comprising the steps of:
- providing a first layer of fabric having a top surface;
- spreading a first layer of adhesive on the top surface of the first layer of fabric;
- adhering a first layer of plastic to the top surface of the first layer of fabric by the first layer of adhesive;
- containing a gel in a pocket arranged above the first layer of plastic;
- positioning a second layer of plastic above the pocket containing the gel, said second layer of plastic having a top surface;
- spreading a second layer of adhesive onto the top surface of the second layer of plastic;
- adhering a layer of insulative material to the top surface of the second layer of plastic by the second layer of adhesive;
- providing a sealed off pocket means with dead air space as additional insulation above the layer of insulative material;
- positioning a third layer of plastic above the sealed off pocket means provided with dead air space as additional insulation, said third layer of plastic having a top surface;
- spreading a third layer of adhesive onto the top surface of the third layer of plastic;
- and
- adhering a second layer of fabric to the top surface of the third layer of plastic by the third layer of adhesive.
