Drinking container and filter assembly

The invention describes a personal, portable drinking bottle made from flexible material. It features a cap to seal its top opening and a unique ring-like formation or groove in its side wall, positioned just below the neck. This formation is designed to prevent the bottle's neck from deforming when the bottle is squeezed. The provided claims focus exclusively on this bottle structure, without detailing any filter components.

Why it matters: While the provided claims only detail the bottle's structure, the classification strongly suggests an integrated filter assembly. Since 2015, advancements in compact and efficient filtration media have made integrating effective personal water filters more feasible and desirable, potentially enhancing the original concept's value.
