Abstract:
A single sheet beverage ingredient filter, comprising:a relatively inwardly located, filtering, inner, bottom section of beverage ingredient filter paper made solely and entirely of a single sheet of water permeable filter paper for support of beverage ingredient resting on the bottom to allow a flow of beverage uniformly and continuously across the entire bottom; and a relatively outwardly located, water impermeable and nonfiltering outer side wall section of beverage ingredient filter paper integrally formed with and continuously and contiguously joined to and surrounding the inner, bottom filtering section of beverage ingredient filter paper and extending upwardly from the bottom to define a water impervious side wall surrounding an open top through which ingredient may be dumped directly onto the bottom section for directing water through substantially the full thickness of any ingredient being supported by the bottom and through all and substantially only the filtering bottom section; said inner bottom section and outer side wall section being integrally formed from a single sheet of ingredient filter paper but in which the bottom section filter paper has a porous structure that is water permeable and the outer side wall section has a structure like that of the bottom section hut which has been fattened and dimensionally reduced relative to the porous structure of the bottom section to reduce the porosity of the outer section to render the outer section substantially water impervious relative to the inner section.
