Drinking Container and Filter Assembly

摘要

A personal, portable drinking container has a bottle with a side wall, a closed bottom, a neck, a reservoir, and a top opening in the neck providing access to the reservoir. A cap is removably fitted on the neck to close the top opening. The bottle can have an annular formation in the side wall below the neck to prevent the neck from deforming when the bottle is squeezed. The side wall can have a pair of squeezable sides and a pair of opposed stiff sides below the annular formation, whereby the stiff sides help the bottle to rebound quickly after each squeeze.
