Abstract
A water treatment system is provided with an untreated water reservoir having a cavity through which a filter assembly may traverse such that untreated water in the cavity passes through the filter assembly into a treated water reservoir. Removal of the filter assembly may be facilitated by a seal disengagement element operable to unseat a seal formed during efforts to direct untreated water through the filter assembly.
Claims19
A water treatment system comprising:
- an untreated water reservoir having a cavity capable of holding untreated water;
- a main body comprising a filter assembly and a treated water reservoir;
- the filter assembly adapted to be disposed within the cavity of the untreated water reservoir, the filter assembly including an inlet configured to be fluidly coupled with the cavity to receive the untreated water, the filter assembly including an outlet configured to discharge treated water;
- the treated water reservoir configured to store treated water discharged from the filter assembly, the treated water reservoir including a first end opening and second end opening, the second end opening of the treated water reservoir being fluidly coupled with the outlet of the filter assembly;
- a wiping seal interface including a seal between a seal engagement surface of the main body and an inner surface of the untreated water reservoir;
- wherein the seal of the wiping seal interface provides a substantially air and water tight seal between an environment and the cavity of the untreated water reservoir, wherein displacing the main body into the cavity of the untreated water reservoir directs the untreated water through the filter assembly into the treated water reservoir;
- and
- wherein the wiping seal interface includes a seal disengagement element operable to contact and unseat the seal to break the substantially air and water tight seal based on movement of the main body out of the cavity of the untreated water reservoir.

A water treatment system comprising:
- an untreated water reservoir having a cavity capable of holding untreated water;
- a filter assembly adapted to fit within the cavity of the untreated water reservoir, the filter assembly including an inlet configured to be fluidly coupled with the cavity to receive the untreated water, the filter assembly including an outlet configured to discharge treated water;
- a treated water reservoir adapted to fit within the untreated water reservoir and configured to store treated water, the treated water reservoir being fluidly coupled with the outlet of the filter assembly;
- a wiping seal interface positioned between respective surfaces of the untreated and treated water reservoirs and operable to facilitate generating a pressure differential to direct untreated water through the filter assembly;
- a cap having a spout for discharging the treated water stored in the treated water reservoir for consumption by a user, the cap having an air passage to a surrounding environment, the air passage and the wiping seal interface configured to facilitate generation of the pressure differential between the untreated water reservoir and the treated water reservoir such that the untreated water in the cavity of the untreated water reservoir flows through the filter assembly to the treated water reservoir;
- wherein the wiping seal interface is operable to break a seal between the surrounding environment and the cavity of the untreated water reservoir to facilitate removal of the filter assembly and the treated water reservoir from the cavity of the untreated water reservoir;
- and
- wherein the wiping seal interface includes a seal element and a seal disengagement element operable to contact and unseat the seal element based on longitudinal movement of the seal disengagement element relative to the seal element.

- a main body comprising:
- a filter assembly adapted to fit within the cavity of the untreated water reservoir, the filter assembly including an inlet configured to be fluidly coupled with the cavity to receive the untreated water, the filter assembly including an outlet configured to discharge treated water;
- a treated water reservoir configured to store treated water, the treated water reservoir being fluidly coupled with the outlet of the filter assembly;
- a cap having a spout for discharging the treated water stored in the treated water reservoir for consumption by a user, the cap including a UV treatment assembly with a UV light source for disinfecting water;
- a wiping seal interface between the main body and an inner surface of the untreated water reservoir, the wiping seal interface including a seal element operable to provide a substantially air and water tight seal between a surrounding environment and the cavity of the untreated water reservoir, the wiping seal interface including a seal disengagement element operable to contact the seal element and break the substantially air and water tight seal based on longitudinal movement of the filter assembly relative to the untreated water reservoir;
- wherein the untreated water reservoir is configured to receive a least a portion of the main body within the cavity of the untreated water reservoir;
- and
- wherein the untreated water in the untreated water reservoir passes through the filter assembly into the treated water reservoir to allow displacement of the main body into the cavity of the untreated water reservoir.
