DETAILED DESCRIPTION OF THE INVENTION

(9) Referring now to FIG. 1 of the drawings, a combined capture and fire containment apparatus 10 can be seen for capturing and containing a burning portable electronic device 22 (FIG. 2) such as a computer, cell phone, tablet, or other electronic device containing rechargeable batteries. The apparatus 10 has a telescoping rectangular prism-shaped lid portion 12 and a rectangular prism-shaped containment box 14. As shown in FIG. 1, the lid portion 12 is attached to the containment box 14 by a pair of telescoping drawer slides 16. The telescoping drawer slides 16 may be provided by conventional drawer slides, such as ball-bearing drawer slides or any other low friction slide mechanism. An important feature of the disclosed embodiments is that the lid portion 12 is rapidly and easily moved from an opened to a closed position and vice versa so that a burning portable electronic device 22 can be captured in as short a time as possible and disposed of in the apparatus 10.

(10) A first handle 18 is provided on an end portion of the lid portion 12 and a second handle 20 is provided on an upper portion of the containment box 14. The first and second handles 18 and 20 are used to open and close the apparatus 10 and to place the apparatus 10 over the burning electronic device 22 to close the electronic device 22, if open, so that the burning electronic device 22 can be captured between the lid portion 12, containment box 14 and telescoping drawer slides 16 as shown in FIG. 1. The first and second handles 18 and 20 may be external handles or may be handles that are recessed into the lid portion 12 and containment box 14.

(11) With reference to FIG. 3, both the lid portion 12 and the containment box 14 are made of heat resistant metal 21 such as steel or aluminum and have a thermal flame retardant insulation 23 infilling between an interior surface of the lid 12 and containment box 14 and the external heat resistant metal 21 of the lid 12 and the containment box 14. The thermal insulation 23 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 well known by those skilled in the art. For example, the insulation may be disposed on an interior surface of both the lid portion 12 and the containment box 14, on an exterior surface of both the lid portion 12 and containment box 14, or on the interior surface and the exterior surface of both the lid portion 12 and the containment box 14. In some embodiments, the insulation may be a heat absorbing phase change material based on inorganic salts or organic waxes that absorb heat and therefore helps to maintain a safe handling temperature for the apparatus 10.

(12) In order to prevent toxic gases and fumes from a burning portable electronic device 22 from escaping from the combined capture and fire containment apparatus 10, one or more multi-stage filters 24 may be provided on the lid portion 12 in flow communication with an interior cavity 26 of the containment box 14 (FIG. 3). Each of the multi-stage filters 24 may include an initial particle filter, a gas fume filter and an optional chemical zone filter 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 filters 24 vent treated gases to atmosphere so that substantially no toxic gas or fumes are released by the burning device. In one embodiment, the filters 24 are two stage filters having a first stage containing a pleated glass fiber filter for collecting and filtering out particulates and a second stage containing activated charcoal for absorbing solvent and acid vapors, toxic fumes, and the like. It will be appreciated that additional or substitute filter elements may be used depending on changes to the chemical make-up of lithium-ion batteries used in portable electronic devices 22.

(13) As shown in FIG. 1, a peripheral edge of the lid portion 12 contains a high temperature sealing gasket 28 that provides an airtight seal between the lid portion 12 and the containment box 14. In an alternative embodiment, the sealing gasket 28 may be attached to a peripheral edge of the containment box 14, or to both the lid portion 12 and to the containment box 14.

(14) Spring-loaded latches 30 are provided on aside portion 32 of the containment box 14 and a catch 34 may be provided on a side portion 36 of the lid portion 12. The spring-loaded latches 30 provide positive sealing between the lid portion 12 and the containment box 14 when the apparatus 10 is in a closed position as shown in FIG. 4. The apparatus 10 may be closed by using first and second handles 18 and 20 to slide the lid portion 12 toward the containment box 14 as shown in FIG. 4. Once the apparatus is closed as shown in FIG. 4, the latches 30 may be engaged.

(15) FIGS. 4 and 5 illustrate the overall dimensions of the apparatus 10. For example, the width (W) may range from about 30 centimeters to about 50 centimeters, a height H ranging from about 6 centimeters to about 10 centimeters and a length L may range from 30 to 45 centimeters. The interior 26 of the containment box 14 for holding the burning portable electronic device may have an interior height (IH) of from about 2.5 to about 5 centimeters and an interior length (IL) ranging from about 20 to about 30 centimeters.

(16) With further reference to FIG. 1, in some embodiments, a shatter-proof window 38 is attached to shoulder edges 40 of the drawer slides 16. The shatter-proof window may be made from a wide variety of materials, including but not limited to, a substantially transparent polycarbonate material. Accordingly, the apparatus 10 may be used to capture a burning portable electronic device 22 that is on a floor or table with the apparatus 10 being used in an upright position as shown in FIGS. 6 and 7, or tongs or heat resistant gloves may be used to place the burning electronic device 22 onto the shatter-proof window 38 with the apparatus 10 being used in an inverted position as shown in FIGS. 8 and 9.

(17) When the burning portable electronic device 22 is on a floor or table, the apparatus 10 is opened, as shown in FIG. 6 using first and second handles 18 and 20 so that the burning portable electronic device 22 can be seen through the shatter-proof window 38 and so that the shatter-proof window 38 shields the user from the burning portable electronic device 22 in case the device explodes. Once the burning electronic device 22 is safely between the lid portion 12, containment box 14 and telescoping drawer slides 16, the first and second handles 18 and 20 may be used to quickly close the apparatus 10 so that the spring loaded latches 30 may be engaged with the catches 34 on the sides of the apparatus 10 as shown in FIG. 7.

(18) FIGS. 10-11 illustrate a spring loaded pivotal scoop 46 attached to a peripheral edge 48 of the containment box 14. The scoop 46 includes a spring 50 and a curved finger 52 attached to the scoop 48. The curved finger 52 engages a fixed finger 54 attached to the lid portion 12 for raising the scoop 48 when the lid portion 12 is slid adjacent to the containment box 14 in a closed position. The fixed finger 54 is attached to the lid portion 12 and engages the curved finger 52 when the apparatus 10 is closed to cause the scoop 46 to raise. The scoop 46 is configured to assist in lifting the burning portable electronic device 22 off of the floor or table so that it can be more easily captured and moved into the interior 26 of the apparatus 10 between the lid portion 12, containment box 14, and telescoping slides 16 when the apparatus is closed as shown in FIGS. 6-7. The spring 50 causes the scoop 46 to deploy in a scooping orientation when the apparatus 10 is opened as shown in the close-up portion of the mechanism in FIG. 11.

(19) An alternate method of using the apparatus includes placing burning electronic device is place on the shatter-proof window 38 as shown in FIG. 8, then closing the apparatus 10 by pushing the lid portion 12 and the containment box portion 14 together as shown in FIG. 9. Once completely closed, and the latches 30 are latched, the gasket 28 provides an air tight seal to prevent toxic fumes and gases from escaping from the apparatus 10 as the portable electronic device 22 burns. Likewise, the multistage filters 24 filter out any toxic gases, fumes and particles that might be generated by the burning portable electronic device 22.

(20) In some embodiments, as shown in FIG. 1, a fluid valve 44 may be disposed in the lid portion 12 in order to flow water or other fire suppressant materials into the interior 26 of the containment box 14 from a fluid source such as a bottle or other fluid container. Fire suppressant materials may be selected from flame retardant foams, and halogenated flame retardant fire extinguishing materials.
