DISPOSABLE INFUSION BAG Russian patent published in 2008 - IPC B65D85/808 

FIELD: food industry, particularly packages for beverage infusion.

SUBSTANCE: bag comprises two chambers filled with products. Chamber walls are made of filtering paper and are connected with each other through common edge. Filament-suspended tag is connected to said common edge. Chambers have common inner wall. One chamber receives water-soluble product (sugar) and non-soluble product (oak bark) having specific gravity less than that of water and weight exceeding that of tea placed in the second chamber. Tag includes two leaves and seals the chambers. Chambers have different shapes. As chambers are immersed in infusion chamber sugar is solved in hot water and leaves the chamber. Oak bark provides bag floating on water surface due to decreased oak bark specific weight in comparison with that of water. Bag floating indicates that sugar has been solved in water and demonstrates beverage infusion time. Bag may provide the appearance of flower or round floating on water surface.

EFFECT: increased manufacturability, production efficiency and use properties.
