Exothermic glove insert

Abstract

An exothermic glove insert for warming fingertips. The thermal inserts are very thin, ergonomically designed heat packs for use on each individual finger or thumb. The inserts have a non-permeable membrane heat pack cover that allows specifically placed pin holes to produce heat according to a desired profile exactly where it needs to be provided.

What is claimed is: 
     
         1 . A thermal insert for a glove, comprising:
 a sealed pouch formed of a non-permeable layer of material defining a cavity therein, the pouch having a notch formed at an end distal from a rounded tip portion;   an exothermic composition contained within the cavity;   a plurality of spaced apart holes defined in the non-permeable layer.   
     
     
         2 . The glove insert of  claim 1 , wherein the exothermic composition comprises: iron, millorganite, charcoal, salt and water. 
     
     
         3 . The glove insert of  claim 1 , wherein the thermal insert is configured to conform to a posterior portion of a user's finger. 
     
     
         4 . The glove insert of  claim 3 , wherein an apex of the notch is defined at a point that is distal to a second knuckle of the user's finger. 
     
     
         5 . The glove insert of  claim 4 , wherein the thermal insert has a width permitting the thermal insert to conform to an upper lateral portion of the user's finger. 
     
     
         6 . The thermal insert of  claim 1 , wherein the non-permeable layer is formed from a polyethylene terephthalate film. 
     
     
         7 . The thermal insert of  claim 5 , further comprising:
 a glove insert having a plurality of finger portions; and   the thermal insert is applied to a posterior portion of one or more of the plurality of finger portions.   
     
     
         8 . The thermal insert of  claim 7 , wherein the thermal insert is applied with an adhesive. 
     
     
         9 . The thermal insert of  claim 7 , further comprising:
 a vacuum sealed envelope formed of an air impermeable material and dimensioned to receive the glove insert.   
     
     
         10 . The thermal insert of  claim 9 , wherein the envelope further comprises:
 a sealing closure operable to selectively open and close the envelope in a sealing engagement.   
     
     
         11 . The thermal insert of  claim 9 , wherein the envelope further comprises:
 an oxygen absorber and a moisture absorber.   
     
     
         12 . The thermal insert of  claim 6 , further comprising:
 a removable sealing film covering the plurality of spaced apart holes.   
     
     
         13 . An exothermic insert configured to be received in a finger portion of a glove, comprising:
 a sealed pouch formed of a non-permeable layer of material defining a cavity therein, the pouch configured to conform to a posterior portion of a user's finger distal from a second knuckle thereof;   an exothermic composition contained within the cavity;   a plurality of spaced apart holes defined in the non-permeable layer.   
     
     
         14 . The insert of  claim 13 , wherein the pouch has a rounded tip portion. 
     
     
         15 . The insert of  claim 14 , wherein the pouch has a notch configured to permit movement of a user's finger about the second knuckle. 
     
     
         16 . The insert of  claim 13 , further comprising:
 a finger element configured to be received on a distal portion of the user's finger; and   an adhesive layer securing the insert to a posterior portion of the finger element.   
     
     
         17 . The insert of  claim 13 , further comprising:
 a removable sealing film covering the plurality of spaced apart holes.
