Abstract: A filter device for coffee or the like which includes an open frame 2 formed of sheet material having predetermined rigidity, such as thick paper, and which is smaller in diameter than a blind-end frame 3. Both the frames are connected by a tubular body part 5 formed of deformable sheet material provided with shape retaining ability having predetermined rigidity and flexibility such as thin paper, non-woven fabric, etc. to compose a cup-like container body 1 having a wider bottom in a shape of substantially truncated cone. The filter device can be placed on a coffee cup for use. When the filter device is not in use, the open frame 2 is folded and pushed into the blind-end frame 3 by means of flexibility of the body part 5 and contracted. For use, the open frame 2 is pulled up to expand the body part 5, and the container body is restored into the cup-like shape and prepared to be poured with hot water.

Abstract: A glass holder is provided which is used to hold a glass stably at the edge of a dish. It has a glass holding body shaped like a cup and a cylindrical mounting frame vertically extending from the underside of the bottom of the glass holding body. The mounting frame is cut horizontally halfway around to form a mounting section so that the edge of a dish can freely be inserted into or removed from the mounting section.

Abstract: A coffee package has a filter assembly double folded and enveloped air-tight in a wrapper in a vacuous or inert gas atmosphere. The filter assembly includes a generally rectangular support plate made up of an intermediate portion with an opening for pouring hot water therethrough and a pair of support legs connected with opposite sides of the intermediate portion. The support legs are formed with coactive nipping members adjacent to their edges such that, when the support legs are folded upright relative to the intermediate portion, the nipping members are firmly engagable with the upper edge of a receptacle to support the whole assembly in the raised position for use. A sack of filter paper open at one end is filled with a weighed volume of coffee powder and adhered to the back of the support plate to cover the opening in the support plate.

Abstract: 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.
