Abstract
Embodiments described herein include a vessel, for example, a beverage container, configured for containing a liquid. The vessel may be formed of a metal body and includes an interior surface barrier layer with a pre-determined surface roughness. In embodiments, the interior surface barrier layer includes a mirror-like, highly reflective finish. In additional or alternative embodiments, the interior surface barrier layer includes an oxide of chromium. In embodiments, the interior surface barrier layer substantially prevents chemical components from the metal body from leaching into the contained liquid. In embodiments, the interior surface barrier layer promotes cleanability and/or sterilization for vessel reuse.
Claims20
A metal vessel for consumable beverages, comprising:
- a metal body configured for containing a liquid beverage, the metal body including food-grade stainless steel having a first metal;
- and
- an interior surface of the metal body configured to receive the liquid beverage, the interior surface having a barrier layer with a substantially nonporous mirror-like finish and a predetermined surface roughness,
- wherein the barrier layer is configured to seal the first metal of the food-grade stainless steel to substantially prevent the first metal from leaching into said contained liquid;
- wherein the barrier layer is configured to substantially prevent one or more contaminants from culturing on the interior surface and to substantially enable the interior surface to be cleanable and hygienic to a predetermined level that is substantially microorganism-free.
A metal vessel for consumable beverages, comprising:
- a metal body to contain a consumable beverage, the metal body comprising one or more contaminants;
- and
- a sealed interior surface configured to substantially seal the one or more contaminants within the metal body, the sealed interior surface including a chromium oxide barrier layer,
- wherein the sealed interior surface is configured to substantially prevent the one or more contaminants from leaching into said consumable beverage,
- wherein one or more contaminants include one or more of the following:
- nickel and lead.
A drinking vessel for consumable beverages, comprising:
- a metal body having an orifice defined by one or more interior surfaces, the orifice is configured for containing a consumable beverage,
- wherein the one or more interior surfaces substantially comprise a chromium oxide barrier layer,
- wherein the chromium oxide barrier layer comprises a mirror-like finish having a reflectivity at least equivalent to an ASTM standard #8 finish,
- wherein the chromium oxide barrier layer comprises a predetermined arithmetic average surface roughness of about 2.5 microinches, and
- wherein the chromium oxide barrier layer comprises a thickness of about 1 nm to about 5 nm.
