Definitions

  • Corrugated cardboard is often used for making boxes, cartons and various packaging (or packaging components) for hot pizza, hot or cold foods and beverages for shipping, carry-out as well as home delivery. Corrugated cardboard is also used as packaging for medications and other temperature sensitive products. The way cardboard is designed creates reinforcement for added strength while the design itself creates pockets of trapped air within layers making up corrugated cardboard. These pockets of trapped air create a mediocre insulating effect.
  • the first commercial non-corrugated paperboard box was produced in England in 1817. Robert Gair invented a pre-cut flat paperboard or cardboard that folded into boxes in 1890. The application of this idea to corrugated boxboard was further developed around the turn of the twentieth century. Corrugated paper often referred to as pleated paper was patented in England in 1856. Next corrugated boxboard was used as a shipping material. A patent was issued to a New York businessman by the name of Albert Jones for single-faced or often referred to as a single- sided corrugated board. This inventor used the corrugated board for wrapping glass. A machine for producing larger corrugated board quantities surfaced in 1874 invented by G. Smyth.

  • corrugated cardboard was still not highly fire resistant at this time as is the present invention. Many wooden boxes and wooden crates were quickly replaced by corrugated paper packaging for economic purposes. By the early 1900s, the trades termed the concept as corrugated paper-board and corrugated cardboard. Since then, many new materials were used to create similar corrugated reinforced packaging designs. Corrugated cardboard was still not highly fire resistant and was considered mediocre in terms of insulating at this time, which is unlike the present invention.
  • corrugated board stock is used more to define a packaging design than the actual materials or combination of materials making up the design due to so many modern, suitable materials.
  • Packaging made of said corrugated board stock is often designed for use as packaging while providing protection and insulation while organizing and for transporting.

  • Even corrugated cardboard packaged explosives would be far safer as the present invention is fire proof.
  • the polymer based aerogel film may be made thicker to add even additional fire protection and additional insulation.
  • Other products, such as flowers, also require temperature controlling packaging systems for the purpose of storing and/or shipping. Therefore, the present invention would be ideal for this purpose as well as many other temperature sensitive products.

  • An example of a non-square pizza box is the shape of an octagon, 8-sided pizza box. Domino's Pizza used such a box. Dominoes more recently adopted a patented D-style hexagon box.
  • Corrugated stock made into packaging for pizza and other hot foods are commonly made in many different shapes while the actual material used to make the corrugated stock frequently varies from manufacturer to manufacturer.
  • thick paper is most often the material of choice for a majority of corrugated board boxes due to being economical and so readily available while having substantial strength for resistance against crushing especially when packages are stacked.
  • the present invention adds value especially in regard to significantly reducing air leakage, air circulation, especially heat transfer or retaining cold, retaining heat or significantly resisting water, fire, dirt, dust and moisture.
  • Corrugated board often used for pizza boxes is known as single wall corrugated box material consisting of two separate outer sheets of flat paper known as facings that are bonded with adhesive to a corrugated (fluted) inner layer, often known as a medium.
  • Architects for thousands of years have used an arch with a curve for strengthening and supporting a span of space.
  • Corrugated fiberboard uses this same principle with paper arranged as arches forming a corrugated medium although cardboard is highly combustible unlike the present invention , which is fire proof. These arches are often referred to as flutes that are bonded to linerboard with adhesive for resistance against pressure from all directions and against bending.
  • the arches When corrugated board is placed on end, the arches form strong columns. These columns are capable for supporting a significant amount of weight. Undesirably, the ends of columns are traditionally left unsealed thereby reduce much needed insulating value, which is unlike the present invention because the Aerogel film seals, fire proofs, and super- insulates these end openings. This protects exposed component edges and internal cavities from fire, air leakage, heat transfer, and water/moisture damage. With the present invention, the Aerogel laminated vertical linerboard also serves as to further protect the flutes from fire, heat transfer, moisture, and damage.
  • Corrugated fiberboard can be specified by means of its construction such as for example single face, single- wall, double- wall as well as edge crush strength, burst strength, flat crush, flute size, weight of components, surface treatments, and coatings. ASTM and TAPPI testing methods are standardized in this industry. The size of the corrugated medium, flute size, combining adhesive, and linerboards can be varied for engineer desired properties for matching a wide range of uses. Double- and triple- wall corrugated board is produced for a higher stacking strength and better resistance against puncture. A corrugated design provides additional impact protection, additional stacking strength and adds mediocre insulating properties by means of the hollow cavities filled with trapped air that tends to have said mediocre insulating effect. The present invention is far more insulating (super insulating) and fire proof.
  • the United States Bureau of Labor Statistics categorizes fast food delivery drivers as drivers-sales workers. Drivers are ranked as the fifth most dangerous job category. Pizza delivery statistically has proved to expose drivers to serious risks. Having an insulating thermal- bag to manage and focus can be a distraction when compared to dropping off a corrugated box, which is more simple and quick. A thermal-bag takes far more time, attention, and can create a distraction from what might be going on in the background, which could be dangerous to the delivery person while constantly delivering to so many unfamiliar neighborhoods as they deliver pizzas to stranger after stranger. By eliminating the insulated thermal-bag while reducing multitasking drivers may at times, under certain circumstances be more prone to avoid robbery, assault, being raped, or being even killed.

  • This film is made entirely of engineered polymers (polymer-based Aerogel film).
  • Polymer-based Aerogel film made entirely of engineered polymers doesn't dust or shed insulation particles, which is unlike the previously developed NASA polymer-reinforced silica Aerogels (X-aerogels).

The film has been confirmed to be extremely effective for preventing heat transfer according to NASA publication of July 28, 2011 and, therefore, is well suited for the present invention.
  • Aerogel film as a manufactured component used for the present invention is extremely low in bulk density compared to most all other solids. It is derived from a gel whereas the liquid component is replaced with a highly-insulating gas resulting is a low- density solid that is extremely effective as a thermal insulation when formed into a film. Aerogel was originally discovered by Samuel Stephens Kistler in the early 1900s and was far too fragile for creating such suitable flexible super-insulating film.

  • Said polymer-based Aerogel film almost nullifies all three methods of heat transfer commonly referred to as conduction, radiation, and convection.
  • Polymer-based Aerogel film is a very poor conductor of heat while serving as good convective inhibitors because air cannot circulate through the lattice.
  • Another example to illustrate the extreme value and improvement of the present invention is how frozen meat and frozen seafood is often shipped. It is customary to use large amounts of ice and/or expensive cooling systems in trucks, airplanes, cargo planes, ships and trains that transport frozen foods.

  • Highly reflective food safe films are commonplace in food packaging and are well known for being highly effective for reflecting radiant heat. For example, this would be an excellent choice for a Pizza Box lid. Radiant heat would be reflected back into a hot pizza for example.
