Abstract: The invention disclosed herein provides a way to engage a used concentrate packet such as a tea bag in a drink container in which a liquid product was made from the concentrate without removing the packet from the container and without having to directly contact the packet. Thus, one need not wet his or her fingers or anything in the area of the container, and the used packet when engaged will not interfere with drinking of the liquid product. The packet is also isolated from the interior of the drink container to inhibit further infusion or dissolving of any concentrate remaining in the packet, thereby to control the strength or concentration of the liquid product without having to remove the packet from the container. In the preferred embodiment the holder defines a compartment into which the used packet may be moved to isolate the packet from the interior of the drink container so as to inhibit further concentrating the liquid product from any concentrate in the packet.
