Abstract
A method of manufacturing an infusion package 10 comprising a porous-walled container 12 for an infusible substance and a support for the container by means of which the container can be mounted on a rim of a drinking vessel. The method comprises (i) making cuts in at least one web of a semi-rigid material in a direction transverse to the web length to define a plurality of support members 14, each cut defining a first end 16 of one support member and a second end 20 of an adjacent support member such that the first end includes a projection 18 and the second end includes a recess 22 the cutting of which recess produces the projection; (ii) bringing two such support members into opposed relationship with the first end of one of the support members disposed opposite the second end of the other of the support members; (iii) positioning an end region of the container between the opposed support members; and (iv) securing that end region to the support members.
