Flame arresting and dispensing cap for gel and liquid fuels for ventless fireplaces

摘要

A container-mounted dispensing structure for dispensing gel or liquid fuel into a fuel-containment reservoir of a ventless fireplace. The dispensing structure having an upstream member and a downstream member which are connected to each other. The upstream member defining a plurality of flame-restricting apertures through which fuel exits the container. The downstream member having a substantially larger dispensing aperture. The number of flame-restricting apertures and their size being selected to prevent flame ingress into the container and to allow sufficient flow into a manifold to facilitate single-stream, splash-free flow of fuel from the dispensing aperture into the reservoir.

1. A container-mounted dispensing structure for dispensing gel fuel into a gel-fuel containment reservoir of a ventless fireplace, the container having a body for a supply of gel fuel and a neck atop the body, the dispensing structure comprising:
a first member at the inner surface of the neck, the first member having a distal end wall and an annular sidewall and defining a downstream always unblocked dispensing aperture; and a second member having a lower edge and an annular sidewall projecting toward the distal end of the first member, the second member engaged to and within the first member and defining a plurality of upstream flame-restricting apertures through which fuel flows from the supply, the first and second members together forming a gel-fuel-gathering manifold between the upstream and downstream apertures, the downstream dispensing aperture being larger than the upstream flame-restricting apertures, the number and size of the flame restricting apertures are selected to (1) prevent flame ingress into the container and (2) allow sufficient flow into the manifold to facilitate single-stream, splash-free flow of gel fuel from the dispensing aperture into the reservoir, the first member having at least one inwardly-projecting annular bead adjacent to the lower edge to maintain the second member in fixed position relative to the first member,whereby the height of the annular sidewall of the second member is substantially the same as the distance between the bead and the distal end wall of the first member.
