US 10,118,758 B2 · Floatable infusion package

Abstract

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 other—to 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.
