A two-piece spill proof open cup (10) is disclosed comprising a container (12) suitable for holding liquids, such as a beverage, and a lid (14). The container (12) has a sidewall (13), a neck (15) adjacent the sidewall (13) and an opening (40) defined by the neck (15). The neck (15) has a flange (28) along an edge (42) of the neck (15) and a plurality of posts (30) adjacent the flange (28). The lid (14) is adapted to fasten to the container (12). The lid (14) has an upper surface (46) external to the two-piece spill proof open cup (10) and a lower surface (48) internal to the two-piece spill proof open cup (10). The lid (14) also has a flap (16), a lid body (25) with a vent (22), a hinge (18) connecting the flap (16) to the lid body (25), a handle (20) on the upper surface (46) and a bead (34) having channels (32). The bead (34) is integrated into the lower surface (48). The lid flap (16) is adapted to form a liquid tight seal between the lid (14) and container (12).

The present disclosure relates to a method of steam-sterilizing liquid-filled medical devices, e.g., filtration and/or diffusion devices like ultrafilters and capillary dialyzers.

A drinking container with an integrated valve that uses surface tension to control the flow of fluid.

A drinking vessel has a cup with a removable lid having at least one inlet-outlet opening which receives an elastic straw-vent assembly having a flexible tubular straw or spout and a ventilation member that defines an air passageway and a vent opening. A vent actuator is operably coupled to the ventilation member and configured to change a state of the ventilation member between a ventilation state and a closed state. A cover movably mounted on top of the lid, shiftable between a closed and an open position, comprises a cam on an inward surface of the cover which is configured to contact the vent actuator during movement of the cover member to change the state of the ventilation member. In the closed position the cover engages the straw, folding the straw against the lid, and in the open position, the straw fluid passageway and the vent opening are unobstructed.

A lid, for attachment to a container holding a liquid for use with a liquid spraying device, a vent duct defining a vent conduit extending through a lid body from a duct inlet end to a duct outlet end. A valve is disposed in the vent duct and is configured to permit air flow in a first direction, from the duct inlet end to the duct outlet end, while preventing liquid flow in a second direction opposite the first direction. A cap extends over the duct inlet end, the cap including a cap interior surface defining an interior air chamber, communicating with the vent conduit, and at least a first passage, communicating between the interior air chamber and a first cap inlet. A tube is coupled to the duct outlet end and has a tube outlet end fluidly communicating with an interior of the container.

A drinking container with an integrated valve that uses surface tension to control the flow of fluid.

A sealed container (1) for beverages, especially pressurised beverages, comprises a cup (2) with an open top (3) and a lip (4) circumscribing the open top, and a sealing lid (5) heat welded to the lip (4). The paperboard lid comprises a micron-sized pressure release aperture (6) providing pressure regulation within the cup when the beverage is disturbed. The container includes a removable transport cap (13) for sealing engagement with the top of the cup (2) having a top panel (14) and a skirt (16) circumscribing the top panel, in which the top panel includes a first annular sealing head (19) configured to abut the sealing lid (5) when the plastic lid is engaged on the top of the cup. 12. A welding machine (33) for sealing the sealing lid (5) to the lip (4) of the cup (5) is also described.
