A drip bag has a body formed of a water permeable sheet, an openable upper end, and hook members formed of a plate-shaped material on outer faces of two opposing body surfaces. The hook member includes: an upper stuck part adhered to the body along its opening in an elongated shape; a center part located below the upper stuck part at the body center in its width direction not to be pulled out; and a hook part not adhered to the body. Two oblique folding lines are formed on the upper stuck part with a center line therebetween, and being more spaced from the center line while extending from a lower to an upper portion of the upper stuck part, the center line bisecting the body in its width direction. A vertical folding line is formed downwardly from immediately below a lower end of the oblique folding lines.

A tea bag system is disclosed that includes a tea bag, a tea bag string, a tea bag tag, and a steep indicator. The tea bag includes a water permeable material that contains tea leaves. The water permeable material enables tea particulates from the tea leaves to diffuse into water when the tea bag is placed in a water-filled container. The tea bag string has a first end and a second end, the first end connected to the tea bag. The tea bag tag connected to the second end of the tea bag string. The steep indicator is operatively associated with the tea bag system. The steep indicator displays discernable indicia that the tea bag has steeped in liquid for designated period of time.

A disposable cartridge for use as a filter in particular for soluble elements, aromatic herbs such as tea, coffee, chamomile, infusion, whose configuration comprises means for securely and stably fixing it without occupying the entire annular diameter of a cup or container, characterized in that it is made up of a symmetrical laminar template (2) whose plantar shape is determined by an upper area of sinusoidal contours (3) with a superior central ridge or rounded tongue (4) followed by curved shoulders (4a) is the middle area of which it is present a groove or opening of oblong configuration (5) with rounded ends (6), which serves as means for cartridge holding (1) with the cup (8) upper perimetric rim (7) in which the lower area of the template (2) has a triangular obtuse-angled body (9) with straight sides (9a).

A sachet compactable coffee filter with bag support made of compostable and/or biodegradable material is provided, including: a filter bag including a cut line in the upper part; supporting tabs welded in the central region of the filter bag including a connecting frame, internal and external supporting structures, with a thin upper and lateral margin of the supporting tabs, and is the part that is welded, using paper welding, to the filter bag; the foldable tabs starting from a first sachet-shaped state to a second state where the internal supporting structure detaches from the connecting frame and the external supporting structure detaches from the internal structure in order to form a tongue that presses the internal part of the receptacle and secures the filter bag by the weld that joins the two, while the external structure presses the external part of the receptacle forming a support for the filter bag.

One embodiment of an infusion package comprises a prepared raw material compartment (10) formed by sealed partitions (12) and (14) and containing prepared raw material (16). Partition (14) separates compartment (10) from a flotation compartment (18) filled with flotation material (20) to cause the package envelope to float in a liquid. Any floatable material which is inert and harmless in the liquid, or a gas bubble sealed in a liquid-tight bag can serve as flotation material. A sealed envelope top (22) carries advertising materials, though advertising labels can be attached to its surface as an option. One end of a string (24) is attached to top (22) and the otherto a conventional label (26). The package envelope can be agitated and removed from the liquid with the help of top (22) or string (24). The envelope can be entirely or in part of a liquid-permeable, heavier-, or lighter-than-liquid, inert and harmless material like paper, fabric, plastic net, perforated plastic film, etc. Other embodiments are described and shown. All embodiments are easy and trouble-free in production, storage and use.
