Abstract: A flow control element (e.g., a baby bottle nipple or a child sippy cup flow control valve) that includes a tube-like wall section defining a flow channel, and a substantially flat membrane supported by the wall section such that membrane impedes flow through the flow channel to an external region. The membrane punctured to form multiple, substantially round pinholes arranged in a two-dimensional pattern that remain closed to prevent fluid flow under normal atmospheric conditions, and open and to facilitate fluid flow rate through the membrane under an applied pressure differential (e.g., when sucked on by a child). The wall section has a greater rigidity than the membrane (which is formed from a relatively highly elastic material). Different sized pinholes are produced using different sized pins, thereby facilitating different flow rates in response to different applied pressure differentials. The pinholes are generated while stretching the membrane in a radial direction.

The regulator valve includes side and bottom walls with apertures formed therein, with the apertures including generally taper shaped portions terminating in irregularly shaped edges. The wave-breaker recess has a sidewall portion that reflects waves of liquid from the regulator valve, and a sloped sidewall portion that defines a channel with the annular sidewall in which the regulator valve is disposed. The inhibitor recesses extend down into the channel to prevent waves of liquid traveling therethrough.

Abstract: A variable flow infant feeding assembly is designed so that a caregiver can select an optimal feeding flow rate without having to change nipples, as may be desired depending upon the age and appetite of the infant as well as the liquid that is being dispensed. Preferably, the assembly includes a baby bottle and a nipple member that has ventilation structure defined therein for permitting replacement air to enter the baby bottle during feeding.

Abstract: A spill resistant container (e.g., a sippy cup) including a flow control element including a membrane defining multiple pinholes for controlling the flow of liquid through a drinking spout. The flow control element is mounted on a cover that screws onto a cup-shaped body such that the membrane is positioned between liquid stored in the cup-shaped body and the drinking spout, which is formed on the cap. The flow control element is formed from a suitable elastomeric material (e.g., soft rubber, thermoplastic elastomer, or silicone) such that the membrane stretches when subjected to a differential pressure. The pinholes are formed by puncturing the membrane using one or more pins having a substantially circular cross-section and sized such that each pinhole is closed by the surrounding elastomeric material when the pins are removed.

The holes are formed during molding of the lid.

Abstract: The valved liquid dispenser allows hands-free operation of the dispenser while preventing leakage caused by positive pressures within the container. The valved liquid dispenser provides a passageway and diaphragm that operate by applying suction to the proximal end of the valve. In another embodiment of the valved liquid dispenser, the diaphragm includes a duckbill or other venting means that is supported by a diaphragm support to allow liquid to flow through the passageway similar to the first embodiment, but also allows for pressure equalization within the container.

Abstract: An improved no-spill cup construction and valve assembly which provides an extremely secure seal against accidental liquid flow from the cup spout. The act of sucking at the cup spout creates negative pressure or a partial vacuum against a valve near the spout, causing the valve to invert which unblocks an opening in the valve. When the opening is unblocked, liquid can flow freely through the valve and spout. When not in use, the valve sits in a resting, closed position, with the valve pressed against a center seal-off, sealing off the opening in the valve assembly. The closed position provides an extremely secure seal against fluid leakage, such that inadvertent spills or even deliberate attempts to force liquid outside of the cup, such as by turning the cup upside down, or shaking the cup, are ineffective. The cup assembly further allows liquid flow to be regulated between regular or maximum flow and minimal flow levels or rates by rotating the position of the valve assembly in the cover of the cup.

Abstract: A valve for use with a cap for a spill resistant cup, the cap including a spout to dispense the liquid and a valve mount extending from the spout to engage with the valve.

A valve mechanism is located in the valve face for controlling a flow of the liquid through the valve mechanism dependent upon a pressure differential across the valve face. The valve mechanism is a valve slit extending through the valve face perpendicular to a mouth opening in the spout and is S-shaped or straight.

Abstract: A drink container for small children includes a container, a lid joined to an upper opening of the container, and a drip prevention element. The lid has a sucking portion for allowing a young child, to suck on to draw out drink contents of the container with the mouth. The lid is formed with a passage for allowing drink contents of the container to pass through. The drip prevention element is arranged in a passage of the lid to block the passage when there is no external sucking force exerted on the sucking portion, and which can bend to effect opening of the passage when there is external sucking force exerted on the sucking portion. Thus, liquid contents can't drip through the lid when a young child is learning to grasp objects with the drink container.

Abstract: A non-spillable beverage container. The container includes a cover having a straw opening and a second vent opening. The vent opening is covered by a diaphragm attached at a plurality of points on the second vent opening. The diaphragm prevents the passage of air through the vent opening. With the vent opening covered, liquid contained within the container is locked within the container and prevented from exiting through a straw inserted within the straw opening. When a user inhales through the straw, air drawn through the straw from the interior of the container causes the diaphragm to bend downwardly and allow the passage of air into the container. The liquid may then exit through the straw. When the user discontinues inhaling through the straw, the diaphragm closes the vent opening and prevents liquid from exiting via the straw.

The valve element includes an angled face cooperating with an internal angled face of the mouthpiece such that when pressure is applied the valve element moves downwardly, opening the mouthpiece orifice 44. The valve element is resiliently biased upwards such that when relaxed it springs back to close the mouthpiece orifice 44 once again, and is biased upwards in the closed position.

Abstract: The invention relates to an “SRS” with suction spout for beverage cans (canteens), bottles, cups or handheld containers that temporarily hold a carbonated fluid or hot drink under pressure and that is closed off with a top, holding an SRS. Spilling of the fluid held therein is prevented during awkward drinking situations such as in cars while driving, walking or other less controlled drinking conditions. The fluid in a beverage can, remains under pressure of the carbonation process while permanent access is possible through the subject SRS. For non pressurized fluids air is entered through the same valve in order to prevent a vacuum in the container when being emptied, which would reduce the fluid flow while drinking. In all situations and positions of the container, no spilling of the fluid is possible. In case of an aluminum beverage cans, the spout is permanently attached to the lid of the can, but may be removable when used for a drinking cup, bottle or handheld container.
