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.

1. A personal, portable drinking container comprising: a bottle having a perimeter side wall with a closed bottom end, a neck at a top end, a top opening at a top edge of the neck, and an interior reservoir within the side wall above the bottom end and accessible through the top opening, the bottle
1. A personal, portable drinking container comprising: a bottle having a perimeter side wall with a closed bottom end, a neck at a top end, a top opening at a top edge of the neck, and an interior reservoir within the side wall above the bottom end and accessible through the top opening, the bottle being formed of a flexible material;a cap removably fitted on the neck to close off the top opening and having a dispenser orifice in the cap;a filter assembly removably coupled to a portion of the container and at least partially disposed in the interior reservoir, the filter assembly comprising: a cage having a side wall with flow openings through the side wall, a top end with an outlet orifice, a closed bottom end, and an annular connector extending outward from the top end or the closed bottom end; anda filter media having a generally cylindrical shape with an open center and disposed between the bottom end, the side wall, and the top end of the cage, wherein the filter media has a finite useful life and the filter assembly includes an indicator that is coupled to the annular connector of the cage and is user positionable to indicate at least one parameter relevant to the useful life of the filter media; andan annular formation in the side wall below the neck and extending circumferentially around the bottle, wherein the neck, the annular formation, and an upper portion of the side wall therebetween are circular about a vertical axis of the bottle,wherein the side wall has a pair of opposed squeezable sides curved concavely toward one another between the annular formation and the bottom end and a pair of opposed stiff sides between the annular formation and the bottom end, the stiff sides being arranged orthogonally about the vertical axis relative to the squeezable sides. 2. The drinking container according to claim 1, wherein the annular formation is a groove formed into the side wall of the bottle. 3. The drinking container according to claim 2, further comprising a ring removably arranged in the groove. 4. The drinking container according to claim 1, wherein the flexible material is a clear polypropylene material. 5. The drinking container according to claim 1, wherein a waist section of the bottle located between the annular formation and the bottom end has a narrower first diameter between the pair of squeezable sides compared to a second diameter between the pair of opposed stiff sides. 6. The drinking container according to claim 1, wherein each of the pair of opposed stiff sides has a depression therein that is vertically oriented. 7. The drinking container according to claim 6, wherein the depressions each have a length that extends the majority of the length of the respective opposed stiff side between the bottom end and the annular formation. 8. The drinking container according to claim 1, wherein at least a portion of the bottle below the annular formation is non-circular about the vertical axis. 9. The drinking container according to claim 8, wherein squeezing the pair of opposed squeezable sides toward one another deforms the bottle below the annular formation but does not deform the neck. 10. The drinking container according to claim 1, wherein when the filter assembly is coupled to the portion of the container, the indicator is arranged within the interior reservoir. 11. A filter assembly for a personal, portable drinking container, the filter assembly comprising: a cage having a side wall with flow openings through the side wall, a top end with an outlet orifice, a closed bottom end, and an annular connector extending outward from the top end or the closed bottom end;a filter media having a generally cylindrical shape with an open center and disposed between the bottom end, the side wall, and the top end of the cage, the filter media having a pleated layer formed of a non-woven, cellulose material and a film layer positioned radially adjacent and in contact with the pleated layer, the film layer formed of a non-woven fabric material; anda one-way check-valve coupled to and seated in an aperture in the closed bottom end aligned with the open center of the filter media,wherein the filter assembly is capable of a liquid flow rate of at least about 15 ml/sec passing through the filter media, andwherein the filter media has a finite useful life and the filter assembly includes an indicator that is coupled to the annular connector of the cage and is user positionable to indicate at least one parameter relevant to the useful life of the filter media. 12. The filter assembly according to claim 11, wherein the filter media has a pore size in the range of about 1-10 micron. 13. The filter assembly according to claim 11, wherein the filter media is capable of reducing the amount of Chlorine in water passed through the filter media by at least 50%. 14. The filter assembly according to claim 11, wherein the pleated layer is impregnated with activated carbon. 15. The filter assembly according to claim 11, wherein the bottom end is an end cap snapped onto the cage. 16. The filter assembly according to claim 11, wherein the pleated layer is positioned radially inward of the film layer. 17. The filter assembly according to claim 11, wherein the indicator is rotatably coupled to the bottom end of the cage. 18. The filter assembly according to claim 11, wherein the indicator is rotatably coupled to the top end of the cage. 19. The filter assembly according to claim 11, wherein the closed bottom end has an annular wall that fits within the side wall of the cage. 20. A personal, portable drinking container comprising: a bottle having a perimeter side wall with a closed bottom end, a neck at a top end, a top opening at a top edge of the neck, and an interior reservoir within the side wall above the bottom end and accessible through the top opening, the bottle being formed of a flexible material;a cap removably fitted on the neck to close off the top opening and having a dispenser orifice in the cap;a filter assembly coupled to a portion of the cap and at least partially disposed in the interior reservoir; andan annular formation in the side wall below the neck and extending circumferentially around the bottle, wherein the neck, the annular formation, and an upper portion of the side wall therebetween are circular about a vertical axis of the bottle,wherein the side wall has a pair of opposed squeezable sides curved concavely toward one another between the annular formation and the bottom end and a pair of opposed stiff sides between the annular formation and the bottom end, the stiff sides being arranged orthogonally about the vertical axis relative to the squeezable sides,the drinking container further comprising a ring removably coupled to the annular formation, wherein the filter assembly has a finite useful life, and wherein the ring includes an indicator that is user positionable to indicate at least one parameter relevant to the useful life of the filter assembly.
