Background Art

[0002] Products that store beverages such as water, coffee, and carbonated beverages for easy carrying and that are provided with lids to prevent the beverages stored inside from leaking out during use are being widely used. The lid is mainly opened and the beverage container is tilted to drink the beverage, or a straw is inserted for convenient use.

[0003] Such conventional beverage containers are formed to basically block contamination caused by external dust or foreign matter, but have a problem in that they have no filtering function for fine plastics generated by the beverage container itself made of synthetic resin (PET).

[0004] Moreover, recently, as well-being and healing have become important social issues, purified mineral water is prepared and drunk instead of tap water. In order to extend the shelf life, these mineral waters inevitably contain additives to prevent corruption. In addition, in the process of drinking only a portion and then drinking it again, there is also the problem of unavoidable contamination due to simply storing it with a cap.

[0005] To this end, Korean Authorized Utility Model No. 20-0481586 discloses a "portable container with easy filter replacement", but since the technology requires a dedicated beverage container that matches the filter, there is a problem that it cannot be applied to existing beverage containers.
