Abstract

An improved insulation wrap is provided with consists of a first layer of flexible material. A second layer of flexible material is secured to the first layer, so as to form a bubble sheeting having a plurality of cavities therebetween. A liquid with reflective particles is carried within the cavities. In one instance cold can be induced into the liquid and in another instance heat can be induced into the liquid, to maintain a desired temperature therein, depending on application and use of the bubble sheeting.

Claims

1. An improved insulation wrap which comprises:

a) a first layer of flexible material;

b) a second layer of flexible material secured in spaced relationship to said first layer, so as to form a bubble sheeting having a plurality of interconnected cavities therebetween; and

c) a liquid with reflective particles carried within said cavities, so that in one instance cold can be induced into said liquid and in another instance heat can be induced into said liquid to maintain a desired temperature therein, depending on application and use of said bubble sheeting.

2. An improved insulation wrap as recited in claim 1, wherein said bubble sheeting is shaped into a receptacle for holding various types of foods therein;

wherein said receptacle further including a closure along one side thereof, to better seal the food within said receptacle.

3. An improved insulation wrap as recited in claim 1, wherein said bubble sheeting is shaped into a bandage and a pad adapted for application to various body parts of a person, to keep the body parts at a desired temperature.

4. An improved insulation wrap as recited in claim 1, further including:

a) a freezer chest for storing said bubble sheeting in a rolled up state therein; and

b) a top lid hinged to said freezer chest and having a cutting edge, so that a portion of said bubble sheeting when pulled out from said freezer chest can be cut off.

5. An improved insulation wrap as recited in claim 3, further including:

a) a housing fluidly connected to said interconnected cavities;

b) an electronic pump within said housing for circulating said liquid through said interconnected cavities;

c) a heating element within said housing for heating said liquid therein; and

d) a thermostat on said housing for regulating said heating element.

6. An improved insulation wrap as recited in claim 3, further including:

a) an inlet tube fluidly connected to said bubble sheeting;

b) an outlet tube fluidly connected to said bubble sheeting;

c) a squeezable housing connected at a top end to said inlet tube;

d) a resealable flap on said top end of said housing, so as to fill said housing with said liquid;

e) a flap valve located in said bottom end of said housing at said outlet tube;

f) a first normally closed check valve located in said inlet tube adjacent said top end of said housing;

g) a second normally closed check valve located in said outlet tube adjacent said bubble sheeting, so that when said housing is squeezed said liquid will flow in one direction from said housing into said bubble sheeting; and

h) a battery operated thermostat located in said inlet tube between said first normally closed check valve and said bubble sheeting, whereby said thermostat will open only at a predetermined temperature.
