Abstract

A hood for depositing vaporized metals on glass container surfaces includes a vaporized metal source that produces vaporized metal; an enclosure, receiving one or more glass containers, comprising at least one side wall and at least one center section having a top above the glass containers; and one or more conduits that fluidly communicate the vaporized metal to an opening in at least one of the top of the center section and the side wall using one or more conduit fans.

Dependent claims

A hood for depositing vaporized metals on glass container surfaces, said hood comprising:

an enclosure, receiving one or more glass containers, and comprising a main hood section located between a first hood section and a second hood section;
said main hood section defining a container path extending from a first end of said main hood section to a second and opposite end of said main hood section, said main hood section comprising a center section plenum having a top panel located above the container path and having first and second plenum walls that extend downward from said top panel and longitudinally along said container path on opposite sides of said container path and that terminate in lower ends adapted to be above a top of the one or more glass containers on said container path;
said first and said second hood sections each having at least one side wall and being arranged parallel to said main hood and said container path, at least one of said first and said second hood sections including an evaporator and a source of a liquid metal in communication with said evaporator, said evaporator vaporizing said metal in said first or second hood section;
a first and a second vertical side shield, said first and second vertical side shields extending longitudinally along the container path and parallel to it and being spaced apart opposite each other across the container path, each having a bottom surface, wherein the bottom surface of the first vertical side shield is adapted to be above the top of the one or more glass containers on the container path so as to not impede flow of the vaporized metal towards the top of the one or more glass containers, and wherein the bottom surface of the second vertical side shield is adapted to be below the top of the one or more glass containers so as to impede the flow of the vaporized metal to allow the vaporized metal to accumulate around a neck finish of the one or more glass containers on the container path;
and
one or more conduits that fluidly communicate the vaporized metal to at least one opening in the top panel of the center section plenum and to at least one side wall using one or more conduit fans.

A hood for depositing vaporized metals on glass container surfaces, said hood comprising:

an evaporator and a source of a liquid metal in communication with said evaporator, said evaporator vaporizing said liquid metal to produce vaporized metal;
an enclosure, receiving one or more glass containers, comprising at least one side wall and a main hood section defining a container path extending from a first end of said main hood section to a second and opposite end of said main hood section, said main hood section including a center section plenum having a top panel located above the container path and having first and second plenum walls that extend downward from said top panel and longitudinally along said container path on opposite sides of said container path and that terminate in lower ends adapted to be above a top of the one or more glass containers on said container path;
a first and a second vertical side shield, said first and second vertical side shields extending longitudinally along the container path and parallel to it and being spaced apart opposite each other across the container path, each having a bottom surface, wherein the bottom surface of the first vertical side shield is adapted to be above the top of the one or more glass containers so as to not impede flow of the vaporized metal towards the top of the one or more glass containers, and wherein the bottom surface of the second vertical side shield is adapted to be below the top of the one or more glass containers so as to impede the flow of the vaporized metal to allow the vaporized metal to accumulate around a neck finish of the one or more glass containers on the container path;
one or more conduits that fluidly communicate the vaporized metal to at least one opening in the top panel of the center section plenum and to the at least one side wall;
one or more fans that direct the vaporized metal to at least one of a top surface and a side surface of the glass container(s) on the container path;
and
a downwardly-facing finish fan carried by the center section plenum of the enclosure.
