Definitions

  • the present disclosure relates to flame mitigation in containers and, more specifically, to flame mitigation devices and containers including the same.
  • Flame mitigation devices are designed to prevent external ignition sources from igniting flammable materials within portable fuel containers (PFCs) and are mounted in a container opening in order to prevent / prohibit an explosion and or “jetting” resulting from a flame entering the interior of a container. These devices limit the propagation of a flame through the opening of a container, preventing the flame from igniting gasses within the main body of the container.
  • flame mitigation devices in PFCs provides an important safety feature (and, in fact, PFCs for consumer use are required to meet the flame mitigation specifications set forth in ASTM F3326), traditional flame mitigation devices also adversely impact the performance and functionality of PFCs such as, for example, significantly reducing the fuel flow rate out of the PFCs and/or inhibiting use of add on features such as pumps that have pickup conduits that need to reach the bottom of the container.
  • the present disclose addresses the performance and/or functionality limitations of currently available PFCs and, more specifically, meets the need for a flame arrestor that enables liquid to be dispensed at a faster rate and/or that will allow a fluid exchange conduit (e.g., a liquid pickup conduit and or a vapor delivery conduit) of an attachment or accessory such as a dispenser (e.g., a spout, pump, container cap with a valve or valves, etc.) access to the liquid at the bottom of a container and/or to the head space in a container.

  • FMDs flame mitigation devices
  • PFCs portable fuel containers
  • the FMDs and PFCs including the same of the present disclosure provide flame mitigation that meets the flame mitigation specifications set forth in ASTM F3326 while maintaining efficient fuel flow and enabling the use of add on features such as pumps that have pickup conduits.
  • the FMDs and PFCs including the same of the present disclosure provide the important safety feature of flame mitigation without or with minimal adverse performance or functionality side effects, thereby raising consumer satisfaction and eliminating the incentive for consumers to attempt to remove the flame mitigation devices in search of improved performance and/or functionality.
  • Flame mitigation devices and or their flame arresting features are basically obstacles and or obstructions to flames which prevent, prohibit and or limit the propagation of a flame through the opening of a container so that the flame cannot igniting gasses within the main body of the container.

More specifically, a FMD and container including the same in accordance with the present disclosure enables the transfer, transport or delivery of air/vapor entering the container directly towards the bottom of the container without interfering or interacting with the flow of liquid exiting the container.
  • the above may be achieved at least in part by a fluid exchange conduit that, in aspects, extends to or within close proximity to the bottom of the container. Alternatively, this may be achieved at least in part by a fluid exchange conduit without the need for the fluid exchange conduit to extend all the way to or within close proximity to the bottom of the container.

  • This flexibility is advantageous for shipping purposes and also for assembly / manufacturing purposes and when it comes to the assembly / manufacturing advantage a curl in this sleeve 1840 will provide clearance when FMD 1800 is overmolded during a blow molding process.
  • the curl will retract the bottom end 1854 of the sleeve 1840 reducing its overall length, which will prevent the bottom end 1854 of the sleeve 1840 from being pinched or sandwiched in the plastic at or near the parting line of the blow mold tool.
  • This flexible characteristic will allow a properly sized sleeve 1840 to be used or even one that’s longer than necessary where if a stiff inflexible FMD was overmolded the overall length would need to be reduced or shortened in order to prevent the bottom end of the FMD from interfering with the blow molding process where it could interefere with the molten plastic or be pinched or sandwiched in the plastic.
  • Shortening the FMD is undesirable in aspects because being able to empty the container is preferable when using a pump and it is often necessary for the pickup tube to be right on or near the bottom of the container. If the FMD has been shortened it will not allow the pump access to all the liquid in the container.
  • the mesh FMD 1800 avoids this because the lower end portion 1854 of mesh sleeve 1840 will allow a pump or it’s pickup tube to rest right on the bottom of a container.

Abstract

La présente invention concerne un dispositif d'atténuation de flamme (FMD) et un système comprenant un récipient et le FMD. Le FMD comprend un corps définissant une partie supérieure et une partie inférieure. Une pluralité de premières ouvertures conçues pour permettre le passage de fluide à travers celles-ci et à l'intérieur du corps sont définies à travers le corps. Le FMD comprend en outre un capuchon d'extrémité définissant une pluralité de secondes ouvertures à travers celui-ci pour permettre le passage de fluide à travers celui-ci et à l'intérieur du capuchon d'extrémité et un conduit s'étendant entre les intérieurs du corps et du capuchon d'extrémité et établissant une communication fluidique entre ceux-ci. Le conduit est conçu de telle sorte que, avec le corps disposé à travers une ouverture au niveau d'une partie d'extrémité supérieure d'un récipient, le capuchon d'extrémité est positionné au niveau ou à proximité immédiate d'une paroi de base au niveau d'une partie d'extrémité inférieure du récipient.
