Containers for holding flowable materials and releasing the same into carbonated water. Methods for preparing a carbonated beverage using containers for holding flowable materials and releasing the same into carbonated water

The commonly used tea bags, such as the square and pyramid designs made from filter paper, offer ease of brewing a drink by steeping the tea bag into a liquid, most notably water. However, these tea bags are not feasible for smaller drinking bottles. In addition, commonly used tea bags have to be steeped for long periods of time, making it not ideal in hurried situations. The shape and size of the tea bag tube make it ideal to fit inside any sized drinking container, such as smaller water bottles. Due to the tea bag tube's disposable nature, as being a filter bag, this invention can easily be pulled out of the drinking bottle and not leave a mess, allowing for an on-the-go format and reuse of smaller water bottles.

A filter assembly for infusing an additive in a liquid. The filter assembly comprises an elongated filter bag that is rigidly reinforced along its vertical length and removably securable to the side of the vessel containing the liquid, to prevent flotation of the filter assembly and its contents. In an embodiment, the lower portion of the elongated filter bag is pre-filled with an additive and closed off to retain the additive in the lower portion. The filter assembly may be disposable. The invention further includes a method of dry-hopping beer using the disclosed filter assembly.
