Abstract: A water purification system includes: a housing; a reservoir mounted to the housing and configured to hold and provide unfiltered water to the housing; a dispensing spout mounted to the housing and configured to dispense filtered water; and a filter assembly. The filter assembly includes: a filter unit with an inlet fluidly connected with the reservoir, and the outlet fluidly connected with the dispensing spout; a filter receptacle configured to connect the filter unit inlet with the reservoir and the filter unit outlet with the dispensing spout; and a locking yoke. The locking yoke is configured to move between a locked position, in which the locking yoke engages the filter unit and retains the filter unit in the receptacle, and an unlocked position, in which the locking yoke disengages from the filter unit to enable the filter unit to be removed from the receptacle.

Abstract: A container assembly is disclosed. The container assembly includes a container that contains a volume. Selected portions of the container assembly may be removable. A spigot assembly may be removed and associated with a filter assembly. A monitoring system can be integrated into the filter assembly. The monitoring system includes a light sensor to sense existence of ambient light when the filter assembly is selectively removed from the container.

Abstract: A container system having an access portal is disclosed. The container system may contain a selected material for access and withdraw through the portal. The portal may be engaged in any appropriate manner, such as with the application of a vacuum or pouring out.

Abstract: The invention relates to container bodies configured to be used in filter-as-you-pour systems, where filtering is achieved as the user pours water from the container. Such container bodies may have an undivided internal storage volume, so as to not include a reservoir compartment for unfiltered water. They may be part of systems configured to filter water both as water is introduced into a container body of the system and as water is poured from the container body of the system. The filter assembly may be attached to the container body at a location proximate the outlet of the system. Filter media of the filter assembly may comprise an activated carbon textile material that presents a curved surface to water passing through the filter assembly. The container body may be configured as a pitcher, carafe, water bottle, jug, or other shaped container.
