Apparatus and methods for placing and attaching formed filters into brewing cups

摘要

A filter setting and sealing apparatus includes a wobble plate mounted to press a filter edge into a plane defined by the top rim of a brew cup. A sealer defined by expandable sealer jaws is moveable into the filter. The jaws are actuated for radial outward expansion to seal the filter to the cup proximate the filter rim and cup edge. A second sealer is used to seal any gaps remaining in the seal after initial sealing. Methods are disclosed.

1. A method for combining a filter and brewing cup, the method comprising the steps of:
receiving said brewing cup with said filter set to a predetermined position with respect to said brewing cup, said filter having an approximately circular top edge and an outside circumferential surface disposed below said top edge; inserting a first sealing apparatus into said filter within said cup; sealing a first portion of said outside circumferential surface of the filter to an inside wall of the brewing cup with said first sealing apparatus and defining discrete seals of said filter to said cup with gaps between said seals; and sealing a second portion of said outside circumferential surface of the filter to said cup, such that said first and second portions of said outside circumferential surface of the filter below the top edge of the filter is sealed in a continuous annular seal to said brewing cup without gaps in said seal.
