Technical Field The present disclosure relates generally to the field of devices and containers suitable for altering a liquid suitable for human consumption. The disclosure also relates to a method of altering a liquid suitable for human consumption.

Background Healthy living and minimizing the impact on the environment have become major trends in the way people live and consume. These trends in combination with increased resource scarcity, in particular potable water, have led many people to engage into the so- called circular economy and consider reusability of products as part of their consuming habits. Ways to alter drinking liquids, in particular products to affect or enhance the taste of a drinking liquid are well known in the art. Known solutions to enhance or modify the taste of drinking water include lyophilized powders or liquid concentrates. These solutions typically require engineered processes to ensure efficient incorporation into the liquid for consumption or make use of non-reusable parts. As part of known solutions for modifying drinking water, tea sachets suitable for preparing drinking tea has become very popular but typically produce non-reusable waste. Other more complex solutions for preparing tea-based beverages are described for example in CN111227590 (Yunlong), CN111184407 (Yunlong), CN111227589 (Yunlong) or in CN211673583 U (Huang).

Known solutions are not always satisfactory in terms of reusability of products and materials while trying to alter the properties of a liquid suitable for human consumption.
