A liquid dispenser for dispensing a consumable liquid from a container. The dispenser includes a cabinet configured to receive one or more containers in an inverted position such that liquid is induced by gravity to flow out of an open interior of the container though a dispensing opening. A positive pressure valve assembly is mounted to the dispensing opening of the container prior to insertion of the container into the cabinet. The valve assembly includes a cap connected to the dispensing opening and a discharge tube extending from the cap. A flow restrictor of the valve assembly is positioned to selectively open and close the discharge tube to control the flow of liquid from the container. A one-way valve is positioned between the open interior of the container and a supply of air. The one-way valve allows air flow into the container as the fluid is discharged to maintain a positive pressure within the container.

A dispensing system including a container and a dispenser. In some embodiments, the container includes a container body, a dispensing opening, and a seal over the dispensing opening. In some embodiments, the dispenser includes a base, a drawer, a piercing tube, and a dispensing tap. In some embodiments, the base is configured to receive the container. In some embodiments, the drawer is moveable relative to the base between a first position and a second position. In some embodiments, the piercing tube is coupled to and moveable with the drawer. In some embodiments, the dispensing tap is in fluid communication with the piercing tube. In some embodiments, the piercing tube is configured to pierce the seal of container when the container is received in the base and the drawer is moved from the first position to the second position.

A chemical transfer coupler including an inlet, an outlet, a chemical flow chamber fluidly connecting the inlet and the outlet, and a probe. The probe extends through the chemical flow chamber and includes a rinse aperture, a probe end fitting, and a first recessed slot. The probe end fitting includes a first end, a second end, and an outer surface. The first recessed slot extends helically along the outer surface from the first end to the second end. The chemical flow chamber fluidly couples the rinse aperture and the outlet. The first recessed slot is positioned at least partially along a flow path extending between the rinse aperture and the outlet.

A fluid dispenser includes a housing, a pump, an outlet nozzle, a reservoir, a liquid passage, an air passage, and a refill container. The pump and reservoir are attached to the housing, and both the outlet nozzle and the reservoir are in fluid communication with the pump. The reservoir has at least one engagement member, and the liquid passage and the air passage are located in the engagement member. The refill container has at least one sealing member, and the refill container is configured to be releasably attached to the reservoir such that the refill container is in fluid communication with the reservoir. When the refill container is attached to the reservoir, the engagement member engages the sealing member to cause the liquid passage and the air passage to be in fluid communication with the refill container.

A fluid storage and dispensing system that safely and efficiently stores all grades of motor oil is provided. The system is configured to accurately dispense motor oil into vehicles. The system may also be used for the storage of and dispensing of other fluids.

A system for advance notification of replacing or ordering a water bottle based on historical consumption data, and a water dispenser. The system includes a server, a water dispenser, a weight sensor, and a user device. The weight sensor measures weights of a replaceable water bottle on the water dispenser at different times and transmits the weights back to the server, so as to make multiple determinations with respect to the weights and accordingly obtain the consumption of the replaceable water bottle over time, thereby reminding a user to replace the replaceable water bottle and to make a new order.

A valve assembly for use with a spout. The assembly includes a slide that includes a side wall, an end wall, a slide flange, and an anti-tamper strap. The side wall includes a dispensing hole. The assembly further includes a sleeve and a cap that includes an inlet, an outlet, and a cap flange. The cap flange includes a strap cavity. The cap is configured to be slidably inserted into a spout, the sleeve is configured to be slidably inserted into the cap, the slide is configured to be slidably inserted into the sleeve, and the anti-tamper strap is configured to be inserted into the strap cavity.

The present invention proves a hydrogen injection apparatus that is good in terms of work efficiency and sanitation at the time of maintenance and that is capable of generating hydrogen water the hydrogen content of which is flexibly adjustable. The hydrogen injection apparatus according to the present invention includes a reference vessel, on the bottom of which a particle having a material for reacting with water to generate hydrogen formed on the surface thereof is placed, the reference vessel being configured to store water for reaction with hydrogen, a communication means for fluidly connecting the interior of the upper side of the reference vessel to the storage water for drinking in the state in which the reference vessel is sealed, and an auxiliary means for increasing injection of hydrogen into the storage water for drinking from the reference vessel through the communication means.

The invention relates to a drink dispensing device which consists of a dividable or single-part cylinder (5), in which stand up bags (7) or bottles (25), (26) are introduced containing beverages that are dispensed through independent taps (10). The device is positioned on a table-top base (3), (4), or on an on-floor base (17), (18), and are connected by a screw (19). The device structure proposed by the present invention may serve in the mounting of one or two stand up bags or even more bags as long as a respective configuration and a respective size are ensured. There is no limitation in size or the type of liquids, which may be alcoholic beverages, juices, oil, vinegar, etc.

A dispenser is provided to receive and hold a bag-in-box container on top of a conventional type water cooler and to control the flow of water from the bag-in-box container into a water reservoir of the water cooler to maintain a desired level of water in the water reservoir. Level control of water in the reservoir is provided by controlling the venting of the sealed reservoir to the atmosphere and/or by controlling the flow of water into the reservoir from the water supply line. Venting control can be through use of a hydrophobic membrane or through use of float valves in the vent, and control of flow of liquid into the reservoir from the water supply line can be by a special float valve that allows high flow capacity at low pressures or through discharge of water from the reservoir. The reservoir can be formed as a flow through passage through a mass of temperature adjusting material.
