• a fire containment case 10 of the invention can be seen for receiving electronic equipment (not shown) that is on fire.
• the containment case 10 has a main exterior housing 12 defined of a base portion 13 and a hinge closure portion 14 having hinge assemblies 14A.
• the exterior housing 12 is preferably of a rectangular configuration of a known size and dimension to accommodate and receive a variety of portable electronic equipment therewithin.
• An airtight sealing gasket configuration 15 is provided and formed by the respective perimeter engagement flanges 13A and 13B of the base and closure portions 13 and 14 as will be well understood by those skilled in the art.
• a common latch system 16 assures closure portion 14 retainment and secures the housing 12 with a sealing gasket assembly 15 and will be described in greater detail with alternate forms hereinafter.
• an internal equipment receiving case 17 is formed within the exterior case housing 12 of the case 10 with thermal flame retardant insulation 18 infilling between the infernal receiving case 17 and fhe exterior housing 12.
• transportation container 19 as best seen in figure 5 of the drawings is generally of a rectangular configuration having a receiving base panel 19A with upstanding interconnected side and end walls 20A and 20B and 20C
• An integral fop panel 21 forms an equipment transport receiving area 22 therewithin.
• the sidewalls 20A and 20B are tapered at their respective opening defined by the enclosure forming in essence a side edge scoop therein.
• a collapsible wire handle assembly 23 is secured to fhe fop panel 21 which will allow for user's grasp and lifting for engaging and receiving electronic equipment while on fire.
• the transportation container 19 is of an overall dimension less than that of the receiving case 17 with optional spacer tabs 21 A extending from the exterior of the side wall 20A so as ⁇ o be slidably received therewithin and spaced same associate ⁇ o fhe inferior thereof as illustrated in solid and broken lines in figure 2 of fhe drawings.
• the thermal insulation 18 hereinbefore described may be of a passive static material chosen from a variety of thermal insulation materials currently available commercially or alternately of an active thermal material 18A as illustrated in figure 2 of the drawings.
• Such an active thermal insulation material has a phase charged change material based on inorganic salts that absorb heat and therefore help maintain the outer case temperature of the containment case housing 12.
• phase change insulation materials are commercially marketed, for example, by PCM Energy Ltd.
• the containment case 10 of the invention has a gas and fume collection filter and retainment system 24 in communication with the interior of the internal equipment receiving case 17.
• the gas and fume system 24 in this example is positioned in the hinge insulated closure portion 14 and may have multiple filter zones including, for example, an initial particle filter 24A, a gas fume filter 24B and an optional chemical zone filter 24C to collect and retain dangerous gases such as carbon monoxide and cyanide that may result from the burning of synthetic resin based materials during combustion.
• the filter system 24 then vents treated gases to atmosphere at 25.
• an evacuation gas canister 26 may be used as an alternate to the filter under negative pressure to collect the gases expelled by the burning electronic devices, not shown, sealed within the equipment receiving case 17 within the containment case 10 as illustrated in broken lines in figure 2 of the drawings as an alternate gas collection system.
• valve fitting 27 is provided allowing for direct
• An auxiliary fire suppression system 28 can be seen in figure 2 of the drawings having a water injection fitting 29 extending through the insulated closure portion 14 of the case 10 in communication with the equipment receiving case 17.
• a water bottle WB shown in broken lines can therefore be attached to the water injection fitting 29 and manually expelled by manual compression into the case 17.
• an alternate canister dispenser 30 of thermal insulating fire retardant foam that would be activated once the case is closed during active use in the presence of burning equipment positioned therewithin. Such firefighting foam is released into the respective equipment receiving case 17 to effectively control gases and temperature and extinguish the fire and is illustrated in broken lines as an alternate suppression system in figure 2 of the drawings in the closure portion 14.
• the alternate containment case 10 insulation 18A can be seen in a portion of figure 2 of the drawings which illustrates, as noted, the positioning of the thermal phase change material insulation 18A against the inside surface S of the exterior housing 12 with a layer of conventional flame proof insulation 18B. Additionally, a flame proof liner 31 surrounds the interior receiving chamber defined by the case 17.
• the sealing gasket assembly 15 is defined by the pair of elongated contoured continuous integrated engagement flanges 13A and 14A extending respectively about the open end edges of the base portion 13 and closure portion 14, as noted.
• an O-ring gasket 32 is fitted within a channel therein and provides an airtight seal therebetween when engaged and secured by the latch assembly 16, as noted.
• an alternate sealing gasket material can be used, such as a graphite material gasket well within the doctrine of the art.
• the latch system 16 of the case 10 being identified as a so-called butterfly twist catch latches to maintain an airtight pressure tight seal between the closure 14 and the base portion 13, as described.
• the case housing 12 construction is preferably defined as heat resistant synthetic resin as wherein an inferior wall of the retainmenf case 17 is of preferably aluminum material with an increase interior and exterior dimensions respectively over that of the primary dimension formed so as hereinbefore described as ⁇ o be sufficient to receive and hold electronic equipment in question.
