摘要： The insert comprises a blank (1) with substantially circular to oval basic outline and at least one fold line (3,5) arranged along a diametric (2,3) and spanning an angle of up to 45 degrees. With an oval outline at least two fold lines converge on a large axis and end at a distance from each other on the large axis so that the insert then has a frusto-conical shape. With a circular outline the blank is folded along two diametrics at right angles to each other oppositely along the fold lines and the filter inside has a substantially conical shape. The folds can be secured against unfolding through imprinting and without using adhesive.

摘要： PCT No. PCT/EP97/02139 Sec. 371 Date Oct. 26, 1998 Sec. 102(e) Date Oct. 26, 1998 PCT Filed Apr. 25, 1997 PCT Pub. No. WO97/40727 PCT Pub. Date Nov. 6, 1997A filter device for brewing beverages from coffee or tea grounds has a support frame comprising a first annular member and at least two radially outwardly projecting supports for placing the filter device onto a rim of a beverage container. The first annular member has a diameter smaller than the diameter of the beverage container. A disposable filter insert enclosing an amount of coffee grounds or tea leaves for brewing a beverage in the beverage container is provided. The filter insert has a seamless conical porous pocket for receiving the coffee grounds or tea leaves. The conical pocket has a cone base facing upwardly and a cone top facing downwardly. The filter insert also has a porous cover covering an opening at cone base. The pocket has finer pores than the cover. The cover sags downwardly and forms a depression. The pocket is folded from a flat sheet, having an oval or circular contour, by folding in opposite folding directions along at least two folding lines extending diametrically through the flat sheet and positioned at an angle of up to 45 DEG to one another. The folding lines are secured against unfolding without using an adhesive by connecting at least the edges of the pocket and the cover to one another. The filter insert is annularly supported at the cone base by the annular member of the support frame such that the pocket is freely suspended from the support frame.
