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.

An adapter to convert a conventional water cooler designed for use with substantially rigid water bottles as the source of water to use of bag-in-box liquid containers as the source of water includes a holder for removably holding a bag-in-box liquid container in place of the water bottle at the top of the water cooler and a liquid supply line connectable to a bag dispensing fitting of a bag-in-box liquid container positioned in the holder and a water bottle opening cap engaging pin above a water reservoir in the water cooler. Water from the bag-in-box liquid container can flow by gravity from the bag-in-box liquid container through the liquid supply line and the water bottle opening cap engaging pin into the reservoir. A water level controller to control the flow of water from the bag-in-box container into the water reservoir to control the level of water in the reservoir can also be included.

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 dispenser base for use with a dispenser for delivering a liquid from an inverted supply bottle is disclosed. A top portion of the dispenser base is where the inverted supply bottle is supported. The dispenser base has a rim. A foot is formed at a bottom portion of the dispenser base. A bottle collar engages the top portion of the dispenser base. The bottle collar is adapted to engage the inverted supply bottle positioned on the bottle collar. A gap in a side of the bottle collar enables a dispenser valve coupled to the inverted supply bottle to be lowered directly downward into the bottle collar engaged upon the dispenser base.

A beverage dispensing system for use with a beverage container includes a base with lower, side and upper external surfaces, a vertically-inclined bore within the base extending a first pre-defined distance into the base from the upper external surface and defines an upper opening in the base, a horizontally-inclined bore within the base extending into the base from the side external surface and defining a side opening in the base connected to the vertically-inclined bore forming a continuous internal channel, an outlet valve secured at the side opening in the base, an adapter assembly accessible from the upper opening in the base including a rigid cap, elastic sleeve and vent line. A flexible tubing extending through the continuous internal channel connects the outlet valve to the adapter assembly.

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 device for storing and circulating drinking water with vortex flow includes a base, a tank and an actuator housed in the base and configured to circulate the drinking water stored in the tank with vortex flow. The base includes an inlet port through which the drinking water is received and an outlet port through which the drinking water is dispensed. The tank is mounted on the base with a sealed engagement and is configured to store the drinking water. The tank has spherical or egg shape and includes an air inlet on an upper portion of the tank through which air can flow in and out of the tank.

System for dispensing a liquid to a user, comprising: a container having a reference container volume and comprising a wall with: a bottom portion, a side portion adjacent to the bottom portion, a shoulder portion adjacent to the side portion, a liquid, in the container, a dispenser, arranged to receive and hold the container, characterized in that: the bottom portion and the shoulder portion have a similar male shape, the dispenser comprises a receiving portion having a female shape arranged to mate either with the bottom portion or with the shoulder portion, so as to stably hold the container.

A fluid dispenser can include a body defining a passageway from an inlet to an outlet, a fluid container configured be received by the body such that the fluid in fluid communication with the inlet, and a contactless valve in fluid communication with the outlet and configured to selectively dispense fluid from the fluid container. A contactless valve configured to dispense a liquid can include an actuator configured to move a plug between a closed position in which the plug prevents the flow of liquid through valve body, and an open position in which liquid can be dispensed through an outlet. The valve can include an activation sensor, a presence sensor, and a controller configured to control the actuator and in electrical communication with the activation sensor and the presence sensor.
