Temperature stabilizing cargo compartment, including a freeze and heat barrier, for transport container constructed with thermal resistant materials
Novel method of preserving the internal environmental air temperature and thereby stabilizing the temperature within the cargo compartment of a transport container, and thereby protecting the cargo itself from degradation due to temperature fluxuations, including a freeze and heat barrier attained through the characteristics of the article of manufacture, composition of matter, and method of preservation of the internal environmental air temperature and proximate cargo within said cargo compartment; along with a machine or devise that is used as either a stand-alone container, or as an insert to retrofit existing containers so as to make said retrofitted devices capable of providing cooling over an extended period of time are disclosed. The inserted cargo compartments described herein are particularly useful for temperature-stabilizing cargo compartment shipping containers that are required to maintain a temperature below ambient for a time sufficient to complete delivery of the container and its contents. The shipping containers can be utilized to cost-effectively transport temperature-sensitive products.
1. A method of making a cargo carrying enclosure for stabilizing an interior air temperature of a temperature stabilizing cargo compartment, the method of making the cargo carrying enclosure comprising:
Providing a plurality of layers forming at least one wall, the at least one wall comprised of temperature resistant materials which insulates interior air within the temperature stabilizing cargo compartment, inhibiting heat infiltration, heat loss, vapor and moisture permeability, and stabilizing the interior air's temperature for a period of <1 to 150 hours; wherein providing the plurality of layers comprises:
providing a first layer;
wherein providing the first layer includes forming the first layer comprised of a micro particle material contained within a vacuum; and
providing a second layer;
wherein providing the second layer includes the second layer forming an interior surface of the temperature stabilizing cargo compartment and is comprised of a moisture resistant polymer, or glass, or metal or carbon; and
wherein providing the second layer further includes exposing the second layer or the second layer's material to a fuming surface modifying gas which provides an antimicrobial agent which becomes a permanent part of a matrix of the second layer or second layer's material; and
providing a third layer;
wherein providing the third layer includes forming the third layer, comprised of a polymer with varying density to form a freeze barrier; and
providing a fourth layer;
wherein providing the fourth layer includes forming the fourth layer comprised of a cooling agent which is a phase change material.
2. The method of making the cargo carrying enclosure of claim 1 , further comprising:
inserting the temperature stabilizing cargo compartment into an existing transport container as a retrofit.
3. The method of making the cargo carrying enclosure of claim 1 , further comprising:
placing one of a medical supply, biological sample, pharmaceutical product or other temperature sensitive material within the temperature stabilizing cargo compartment whereby a constant or near constant temperature must be maintained during transportation.
4. The method of making the cargo carrying enclosure of claim 1 , further comprising:
providing a fifth layer comprised of an air hardened ridged polymer which serves as an outer layer of the cargo carrying enclosure.
5. The method of making the cargo carrying enclosure of claim 1 , further comprising:
providing a first cooling or heating apparatus located within the temperature stabilizing cargo compartment and comprises at least one of ice, a gel pack, a phase change material, energy emitting crystals, and a material causing a heat causing chemical reaction, composite material causing a chilling chemical reaction, a mechanical cooling or heating apparatus or a compressed gas.
6. The method of making the cargo carrying enclosure of claim 1 , wherein exposing the second layer or the second layer's material to the fuming surface modifying gas comprises:
exposing the second layer or the second layer's material to the fuming surface modifying gas in a fuming chamber which may be, but is not limited to a fluidized bed apparatus; and
measuring a dwell time and concentration level of the provided fuming surface modifying gas in order to form a treated surface that can be anywhere from 0 to 50 microns deep from the interior surface of the second layer or the second layer's material; and
neutralizing an exposed material of the second layer or the second layer's material;
contacting the antimicrobial agents with the second layer or second layer's material to become the permanent part of the matrix of the second layer or second layer's material which provides properties such as antimicrobial, antistatic, hydrophobic, bondability, and barrier when desired;
wherein the antimicrobial agent of the second layer or the second layer's material is comprised of silver, copper, zinc, and other antimicrobial agent that can become a permanent part of the matrix of the second layer or second layer's material from a depth of 0 to 50 microns from the interior surface of the second layer or second layer's material which has been exposed to the fuming surface modifying gas and providing certain properties to the interior surface of the second layer or second layer's material such as antimicrobial, antistatic, hydrophobic, bondability, and barrier when desired.
7. The method of making the cargo carrying enclosure of claim 1 , further comprising:
providing an absorber for absorbing vapor and liquid condensation within the temperature stabilizing cargo compartment.
