A fluid filtration system for use in a lid of a fluid container, such as a water bottle or water jug, that is adapted to receive a quick disconnect fitting and a pressurization source. The quick disconnect fitting is connected to flexible tubing which can be used to withdraw fluid from the water bottle by using pressure as a motive force. A fluid filtration system for use in a lid of a fluid container, such as a water bottle, water jug, or barrel that comprises a lid configured to attach to a container. The filter is in fluid communication with the lid through an outlet port. An external pressure source pumps the fluid through the filter through an outlet valve on the outlet port of the lid.

A filter baffle assembly, including a filter cap engageable to the mouth of a container, the filter cap including a filter vent situated the filter cap, and a gas permable baffle interposable between the mouth of the container and the filter vent, the baffle protecting the filter vent from contact with the contents of the container. A gas permeable baffle for protecting a filter vent from contents of a container, the baffle including at least one perforation, the baffle being interposable between a container mouth and a filter vent housed within a container cap. A method of protecting a filter vent from the contents of a container, including the steps of sealingly engaging a gas permeable baffle to the mouth of a container; engaging a filter cap, including a filter vent, to the mouth of the container; permitting gas exchange between the container interior and the filter vent, through the baffle; and, with the baffle, protecting, the filter vent from contact with container contents.

A filter baffle assembly including a filter cap engageable to a mouth of a container, the filter cap including a filter vent situated within an inner space of the filter cap, and a liner disposed between the filter vent and a gas permeable baffle engaged to a mouth of the container, the baffle including at least one perforation to permit gas exchange between an interior of the container and the filter vent, and to protect the filter vent from contact with contents housed in an interior of the container. A welded baffle liner assembly for protecting a filter vent from contact with the contents of a container, including a gas permeable baffle having at least one perforation welded to a liner, the welded baffle liner assembly being interposable between a mouth of the container and a filter vent housed within a cap engageable to the mouth of the container. A method for protecting a filter vent from the contents of a container.

The invention relates to a plastic injection molded cover for a liquid container for a spray gun. The cover includes an elongated tapered filter arranged in a connecting spout and including a filter frame which a integrally provided in one piece with the cover and into which a filter medium is embedded. The covers are stackable, wherein the filters are inserted into each other and can be longer than a distance of stacked covers.

A development apparatus to and from which a toner container is attachable and detachable includes a developing roller, a storage unit configured to store toner to be carried by the developing roller, an attachment unit to and from which the toner container is attachable and detachable and provided with a reception port for receiving toner from the toner container to the storage unit, an opening through which an inside of the storage unit and an outside of the storage unit communicate with each other, a filter configured to cover the opening, permit a passage of air and disturb a passage of toner, and a main unit shutter movable between a non-communication position and a communication position and configured to shield the opening when the main unit shutter is located at the non-communication position and open the opening when the main unit shutter is located at the communication position.

A screw cap for containers comprises a screw cap body (10) and an expandable core seal (24) with an annular sealing element (30). A peripheral part (36) of a seal energizing clement (38) expands radially as the screw cap body (10) is screwed onto a container. The peripheral part (36) is joined to a backing (34) of the annular scaling element (30) which comprises a plurality of separate, axially extending segments (42, FIG. 4). The axial compression of the seal energising clement (38) thereby not only makes the adjacent part of the scaling element (30) tend to expand radially, but also makes the axially extending segments (42) tend to rotate upwardly and outwardly. A more evenly distributed sealing pressure of the annular sealing element (30) results.

A container includes a two-piece lid, a base, and an O-ring. The two-piece lid includes a plate and a connector including a first leg with internal threads and a second leg. The base defines a cavity with an open end and a closed end and includes a collar with external threads. The O-ring is configured to form a seal between the two-piece lid and the base. The internal threads on the first leg of the connector engage the external threads of the collar responsive to rotation of the two-piece lid relative to the base. The second leg of the connector drives the plate towards the base responsive to the internal threads on the first leg of the connector engaging the external threads of the collar. The O-ring forms the seal as the internal threads on the first leg of the connector engage the external threads of the collar.

An article includes a permeable material having a surface; and a hydrophobic coating on the surface forming a hydrophobic surface, the hydrophobic coating being free of fluorine, and the hydrophobic surface having a water-contact angle of 95 degrees or greater. The article may be a vent. A method of making the hydrophobic article includes applying a hydrophobic material onto a permeable material; and curing the hydrophobic material to form a hydrophobic surface. The hydrophobic coating may include siloxane.
