Abstract: A leak-proof closure (10) for dispensing liquid beverages from a container. The closure (10) contains a outlet passage (14) which is open at both ends. Within outlet passage (14) there is a membrane (13) which denies communication between the interior of the container and the flow opening (15). When external suction is applied to the end of outlet passage (14), membrane (13) sealingly disengages from circumferential seal member (12). This allows the contained beverage to egress through the flow opening (15). When the external suction is removed, membrane (13) automatically sealingly engages with circumferential seal member (12).

Abstract: Drink spout systems for use with drink containers. The drink spout systems are configured to easily pierce a drink container or a seal across an opening in the drink container to access the drink fluid contained within the drink container. The drink spout system may include a valve assembly to regulate the flow of the drink fluid through the drink spout. The drink spout system may additionally or alternatively include a valve assembly that is configured to prevent drink fluid from being unintentionally dispensed from the drink container, such as when the drink container is pierced by the drink spout system or when the drink container is tipped over or dropped. The drink spout system is particularly useful on aseptic drink pouches, aseptic drink boxes, drink bottles and other similar drink containers.

Abstract: A valve for preventing the flow of fluid when the temperature of the fluid is above a predetermined threshold, the valve including: a body having at least one opening for allowing the fluid to pass when the temperature of the fluid is below the predetermined threshold; and a shape memory or bi-metal actuator for substantially closing the at least one opening when the temperature of the fluid is above the predetermined threshold to prevent the fluid from passing.

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 no spill training cup includes a cup and cover with a drinking spout in the cover. The cover also has a vent opening for maintaining the ambient pressure in the cup with the vent opening being covered by a hydrophobic membrane that allows the flow of air into the cup but prevents liquid from flowing out of the cup through the vent opening. A valve housing is attached to the cover on the inlet side of the spout. The valve includes a diaphragm supported in the housing and biased to engage a valve seat in the housing to prevent flow of liquid from the cup to the spout. When a child sucks on the spout, the pressure on the outlet side of the diaphragm causes it to disengage the valve seat and allow the liquid to flow out of the cup through the spout. When the child stops sucking on the spout, the valve immediately returns to its closed position on the seat so as to prohibit the flow of liquid from the cup through the spout.

Abstract: A reclosable lid for a drinking cup comprising a base and a cap in mating relationship which can rotate relative to each other.

Each sidewall includes a protrusion extending therefrom shaped to fit within one of the first and second apertures. The cover pivots relative to the cover receiving portion so as to engage either the first aperture or the second aperture, and when the protrusion on one sidewall of the cover is pivoted towards the first aperture, the protrusion on the other sidewall simultaneously pivots away from the second aperture.

Abstract: A sports bottle cap having a pressure differential valve is provided which allows water to flow out through the bottle cap only when the bottle is inverted and squeezed or alternatively a straw may be threaded through the pressure differential valve, thereby deactivating it, and attached to the bottle cap allowing the user to draw liquid from the bottle through the straw. In operation the bottle cap of the present invention allows the user to dispense fluid from within the bottle in two different ways. The first manner of use allows liquid to be dispensed only when the bottle containing the liquid is inverted and squeezed. Squeezing causes the pressure to increase on the inside of the bottle thereby causing the pressure differential valve to open and liquid to exit; however, when the bottle is not squeezed the pressure differential valve remains in the closed position sealing bottle.

Abstract: This invention is a Travel Mug, featuring airtight, no leak, easy opening, automatic closing, valve means. The invention provides the benefit of ensuring no beverage emerges from the inside of the container unless the opening mechanism is activated. Even with the additional pressure of very hot coffee, and even when shaken, the sealing mechanism remains leak-proof. This is accomplished by utilizing standard Rubber O-rings (125). Rubber O-rings (125) are positioned in intimate contact with O-Ring Seats (85) while surrounding Counter-bores, Bottom (90). A Spring (150), applies distancing pressure between Crossbeam (140) and Spring Seat (75). Said distancing pressure is transmitted to Qty 2, Stem (120), to Qty 2, Disk, O-ring (105), to Qty 2, O-Ring Groove (110), and ultimately onto Qty 2, Rubber O-Ring (125). Said pressure exerted on Rubber O-Ring (125), between the bottom of O-ring Groove (110) and O-ring Seat (125) causes airtight, leak-proof seals, or “valve means”.

Abstract: A drinking cup assembly including a cup having an open end; a cap adapted to enclose the open end, the cap including a drinking spout and an air vent and mating surfaces adjacent or incorporated into the drinking spout and the air vent; and a flow control valve including two stacks adapted to engage the mating surfaces, each of the two stacks having a concave valve face at a top portion thereof.

Abstract: A flexible member is fabricated with side walls forming a chamber which is coupled to a liquid source on one side and has a slit through an end wall on the other side. The end wall is generally curved toward the chamber on its interior surface. The exterior surface of the end wall has ridges adjacent to the slit that extends through the end wall. Deformation of the side walls of the flexible member as by biting causes the end wall with the slit to deform and open the slit which otherwise is retained closed by the walls of the flexible member. This action establishes fluid dispensing from the source through the slit. The thickness of the end wall varies over its distance creating weaken areas in the end wall. These weakened areas create areas in which the end wall deforms opening the slit. In addition to the foregoing, the interior surface forming the chamber has a minimal surface area. The surface is smooth, allowing easier cleaning of the chamber.

At the end projecting into the second compartment the tube features a closure (44,46) which is closed in a fluid-tight manner when the pouch is in the unopened state and contains a valve element (58, 56) which, under the action of pressure from the side, frees a through-flow channel (37) and which closes automatically.

Abstract: The invention relates to a “flow control element” with suction spout for (metal) carbonated beverage cans (canteens), cups or handheld containers that hold temporarily a carbonated fluid or hot drink under pressure and that is closed off with a leak proof cover. Spilling of the fluid held therein is prevented during awkward drinking situations such as in cars while driving, walking or other less controlled drinking situations. The fluid in a beverage can, remains under pressure of the carbonation process while access is possible through the subject flow control element when a suction is applied to the spout. For non pressurized fluids an air inlet vent is provided to prevent the suction of a vacuum in the container, thereby reducing the fluid flow while drinking. In all situations and position of the container no spilling of the fluid is possible.

Abstract: A container for dispensing a predetermined amount of liquid through a dispensing tube is disclosed. A valve is dimensioned to contain and dispense a predetermined about of liquid and dispense the liquid through a dispensing tube in contact with the valve. The liquid is in fluid contact with the inlet port when the base is in a first position and out of fluid contact with the inlet port when the base is in a second position. Thus, the valve fills with liquid when the container is in a substantially horizontal position while angling the container removes the liquid from contact with the valve and stops the fluid flow. Preferably the container has a sealable, watertight lid that receives the dispensing tube and incorporates vent holes to enable airflow into the container. The fluid inlet port can be placed in the side or top of the valve. The valve can alternatively be a tube with fluid and tube inlets in fluid communication.
