Abstract: A down-flow drinking straw that delivers liquid below a drinking vessel while eliminating siphoning to avoid spills. The straw has a first straight supply tube portion connected by an adjustable bend to a pickup tube portion with a liquid reservoir just below the adjustable bend. The adjustable bend is biased to a normal position, such that the supply tube portion is above the reservoir when the straw is released. Once the supply tube portion is above the reservoir, the reservoir provides a volume of liquid to reverse the siphon and pull the remaining liquid in the supply tube portion back into the vessel. A first embodiment has a reservoir in the form of an increased diameter portion that extends from below the adjustable bend downwardly. At the bottom of the increased diameter portion, the pickup tube may neck down to a smaller diameter to reduce the flow rate or the pickup tube has an increased diameter along its entire length, to maximize the return flow rate.

Abstract: A consumable beverage dispenser is provided having a collapsible beverage container, a valve assembly, and a flexible tube or straw. The collapsible beverage container has at least one opening and the valve assembly is secured to the container at the opening. The valve assembly includes a flexible diaphragm disposed across the flow path such that beverage flow is permitted only outwardly from the container. The flexible tube extends outwardly from the valve assembly. When a user exerts sucking action on the end of the flexible tube, beverage is made to flow from the container out through the one-way valve assembly and into the flexible tube. As beverage is withdrawn, the container collapses and, when the user stops drinking, the flexible diaphragm closes to prevent air and back flow from entering the container. In one embodiment, the flexible tube is slidable within the valve assembly between an open and a closed position.

Abstract: An overcap assembly for a fluid container (12), such as a baby bottle, protects the nipple (14), or other fluid dispenser, from contamination and from leaking when the overcap (18) is in the protective, covering position. The overcap has an opening (41) in its top through which the nipple extends once a lid (43) has been removed and the overcap has been shifted from a stable protective position surrounding the nipple to a stable enabling position exposing the nipple for use without removing the overcap from the collar (16). The lid is preferably tethered, hinged or otherwise connected to the overcap.

Abstract: A drinking mug for small children, handicapped and hospital patients, comprising a cup, a lid and a suction tube, is configured in an airtight manner so that only access to the inside of the mug is through the suction tube. Tightness is achieved by disposing the suction tube on the inside of the lid on a drinking spout and by providing a sealing ring in the joint between the lid and the cup. Due to the airtight construction, when liquid is sucked up an under pressure is created inside the mug which subsequently empties the suction tube of liquid. Correspondingly, an attempt by the liquid to run out through the suction tube when the mug is tipped over is counteracted by the siphon effect which results from the airtight construction.

Abstract: A removable top for use with drinking bottles has a first opening with a pop-up valve and a second opening for receiving a straw. This allows the user to either drink directly through the pop-up valve, or through a straw inserted through the straw opening with the pop-up valve serving as a vent. A removable cap can be used to seal the straw opening when it is not in use. The cap is tethered by a flexible strap to a ring around the base of the pop-up valve. The cap can be secured to a detent in the top for temporary storage when it is not being used to cover the straw opening. In one embodiment, the top is domed with the pop-up valve located at the top of the dome. The straw opening passes through a second raised collar extending upward to an elevation substantially in line with the base of the collar around the central opening. The detent is formed in the top surface of a third raised collar that also extends upward to an elevation substantially in line with the base of the collar around the central opening.
