A filter assembly for providing a filtrate such as coffee has a sack of filter paper adhered to the back of a foldable support plate. The support plate is constituted by an intermediate portion with an opening for pouring hot water therethrough, which is covered by the filter sack, and a pair of support legs connected with the opposite sides of the intermediate portion to have the latter therebetween. Each support leg is formed with at least one slot which extends symmetrically with respect to the longitudinal centerline of the support plate to define a plurality of coactive locking members, which are firmly engagable with a receptacle to support the filter assembly upright stably thereon when the support legs are folded relative to the intermediate portion along preselected fold lines. The locking members may be defined by a pair of slots or a single generally U-shaped slot at each support leg, for example. |
