Definitions
- the present invention relates generally to counter mount dispensing systems, and more particularly to counter mount dispensing systems that may be filled from above the counter in a sanitary method, and sanitary refill units for such dispensing systems.
- Liquid dispenser systems such as liquid soap and sanitizer dispensers, provide a user with a predetermined amount of liquid upon actuation of the dispenser.
- Some dispensing systems are mounted to a counter top and have a spout on top of the counter while having pumps and containers for holding liquid that are located under the counter. These types of systems are commonly referred to either as under-counter mount dispensing systems or counter mount dispensing systems.
- the term counter mount or under-counter mount is used to describe a dispenser system that has a spout located above the counter and the liquid that is dispensed is retained below the counter.
- the first has a refillable container that a user removes, refills with liquid and reinstalls, or simply pours liquid into the opening that is located above the counter in some manual dispensers. These types of dispensers are not desirable because bacteria can grow in the container and contaminate the liquid.
- Another type of dispenser has a refill unit that includes a liquid pump and a container. When the container is empty, a user must go underneath the counter, remove the empty refill unit and thrown it away. The new refill unit is installed from underneath the counter. Although these types of refills are more sanitary than refilling the container, these types of refill units require a user to go underneath the counter to refill the dispensing system.
- One exemplary refill unit for a counter mount dispenser includes a collapsed bag and a tube extending down into the collapsed bag.
- a fitment is secured to the collapsed bag.
- the fitment has a filling orifice.
- a pump for pumping fluid out of the bag is also provided.
- the collapsed bag fits through an opening in a countertop so that the collapsed bag may be inserted from above the countertop through the opening and at least a part of the collapsed bag extends below the countertop.
- the collapsed bag is configured to be filled with a liquid after being inserted through the opening in the countertop and the volume of the collapsed bag expands when the collapsed bag is filled with liquid.
- An exemplary refill system for a counter-mount dispenser includes a container for holding a liquid.
- a refill bag having a width and a length is also provided.
- a tube extends into the refill bag.
- the refill bag is folded toward the tube to reduce the overall width of the refill bag so that it fits through a standard hole in a countertop.
- the container is configured to be releasably placed in fluid communication with the refill bag to transfer fluid from the container to the refill bag after the refill bag is inserted through the hole in the countertop and the refill bag unfolds as it fills with liquid.
- An exemplary “never out” counter-mount dispenser system includes a spout for mounting above a countertop, a first container for mounting below a countertop and a second container for mounting below a countertop. At least a portion of the spout is movable to expose an opening from the spout to the first container and an opening from the spout to the second container.
- the first container is for receiving a first refill bag and the second container is for receiving a second refill bag.
- the exemplary system includes circuitry for causing the never out counter-mount dispenser system to dispense fluid from a first refill bag in the first container until the first refill bag is empty. It also includes circuitry for causing the never out counter-mount dispenser system to dispense fluid from the second refill bag in the second container when the first refill bag is empty.
- Another exemplary counter-mount dispenser includes a housing mountable on a countertop. At least a portion of the housing is movable to expose an opening through the counter. An actuator is provided for causing a fluid to be pumped from a refill bag. A receiving area is provided for receiving a first empty refill bag and at least a portion of the first empty refill bag is configured to pass through the opening. The first refill bag is inserted into the dispenser from above the counter when the refill bag is empty and the first refill bag is fillable while in the dispenser. The first refill bag is also configured to be removed from the counter-mount dispenser after the fluid is pumped out of the first refill bag.

One exemplary refill unit for a counter mount dispenser includes a collapsed bag and a tube extending down into the collapsed bag. A fitment is secured to the collapsed bag. The fitment has a filling orifice. A pump for pumping fluid out of the bag is also provided. The collapsed bag fits through an opening in a countertop so that the collapsed bag may be inserted from above the countertop through the opening and at least a part of the collapsed bag extends below the countertop. The collapsed bag is configured to be filled with a liquid after being inserted through the opening in the countertop and the volume of the collapsed bag expands when the collapsed bag is filled with liquid.
Description
- The present invention relates generally to counter mount dispensing systems, and more particularly to counter mount dispensing systems that may be filled from above the counter in a sanitary method, and sanitary refill units for such dispensing systems.
- Liquid dispenser systems, such as liquid soap and sanitizer dispensers, provide a user with a predetermined amount of liquid upon actuation of the dispenser. In addition, it is sometimes desirable to dispense the liquid in the form of foam by, for example, injecting air into the liquid to create a foamy mixture of liquid and air bubbles. Some dispensing systems are mounted to a counter top and have a spout on top of the counter while having pumps and containers for holding liquid that are located under the counter. These types of systems are commonly referred to either as under-counter mount dispensing systems or counter mount dispensing systems. As used herein, the term counter mount or under-counter mount is used to describe a dispenser system that has a spout located above the counter and the liquid that is dispensed is retained below the counter.
- There a few basic types of under-counter mount systems. The first has a refillable container that a user removes, refills with liquid and reinstalls, or simply pours liquid into the opening that is located above the counter in some manual dispensers. These types of dispensers are not desirable because bacteria can grow in the container and contaminate the liquid. Another type of dispenser has a refill unit that includes a liquid pump and a container. When the container is empty, a user must go underneath the counter, remove the empty refill unit and thrown it away. The new refill unit is installed from underneath the counter. Although these types of refills are more sanitary than refilling the container, these types of refill units require a user to go underneath the counter to refill the dispensing system.
- Exemplary embodiments of dispensing systems and refill units for dispensing systems are provided. One exemplary refill unit for a counter mount dispenser includes a collapsed bag and a tube extending down into the collapsed bag. A fitment is secured to the collapsed bag. The fitment has a filling orifice. A pump for pumping fluid out of the bag is also provided. The collapsed bag fits through an opening in a countertop so that the collapsed bag may be inserted from above the countertop through the opening and at least a part of the collapsed bag extends below the countertop. The collapsed bag is configured to be filled with a liquid after being inserted through the opening in the countertop and the volume of the collapsed bag expands when the collapsed bag is filled with liquid.
- An exemplary refill system for a counter-mount dispenser includes a container for holding a liquid. A refill bag having a width and a length is also provided. A tube extends into the refill bag. The refill bag is folded toward the tube to reduce the overall width of the refill bag so that it fits through a standard hole in a countertop. The container is configured to be releasably placed in fluid communication with the refill bag to transfer fluid from the container to the refill bag after the refill bag is inserted through the hole in the countertop and the refill bag unfolds as it fills with liquid.
- An exemplary “never out” counter-mount dispenser system is also disclosed. The system includes a spout for mounting above a countertop, a first container for mounting below a countertop and a second container for mounting below a countertop. At least a portion of the spout is movable to expose an opening from the spout to the first container and an opening from the spout to the second container. The first container is for receiving a first refill bag and the second container is for receiving a second refill bag. The exemplary system includes circuitry for causing the never out counter-mount dispenser system to dispense fluid from a first refill bag in the first container until the first refill bag is empty. It also includes circuitry for causing the never out counter-mount dispenser system to dispense fluid from the second refill bag in the second container when the first refill bag is empty.
- Another exemplary counter-mount dispenser includes a housing mountable on a countertop. At least a portion of the housing is movable to expose an opening through the counter. An actuator is provided for causing a fluid to be pumped from a refill bag. A receiving area is provided for receiving a first empty refill bag and at least a portion of the first empty refill bag is configured to pass through the opening. The first refill bag is inserted into the dispenser from above the counter when the refill bag is empty and the first refill bag is fillable while in the dispenser. The first refill bag is also configured to be removed from the counter-mount dispenser after the fluid is pumped out of the first refill bag.

The light emitting diodes may, for example, provide indication of the status of thedispensing system 1100 or the status of one or more refill units (not shown) located within thedispenser system 1100.Object sensor 1104 and indicator(s) 1106 are in circuit communication withprocessor 1122, which is located inelectronics package 1120 located belowcounter top 1108. - Although the electrical components are described as being in certain locations, or as being part of an “electronics package,” the components may be located in any suitable location and more or less components may be included. The term electronics package is merely used for convenience and is not meant to limit the number of components or their location.
- “Circuit communication” as used herein indicates a communicative relationship between devices. Direct electrical, electromagnetic and optical connections and indirect electrical, electromagnetic and optical connections are examples of circuit communication. Two devices are in circuit communication if a signal from one is received by the other, regardless of whether the signal is modified by some other device. For example, two devices separated by one or more of the following—amplifiers, filters, transformers, optoisolators, digital or analog buffers, analog integrators, other electronic circuitry, fiber optic transceivers or satellites—are in circuit communication if a signal from one is communicated to the other, even though the signal is modified by the intermediate device(s). As another example, an electromagnetic sensor is in circuit communication with a signal if it receives electromagnetic radiation from the signal. As a final example, two devices not directly connected to each other, but both capable of interfacing with a third device, such as, for example, a CPU, are in circuit communication.
- Also, as used herein, voltages and values representing digitized voltages are considered to be equivalent for the purposes of this application, and thus the term “voltage” as used herein refers to either a signal, or a value in a processor representing a signal, or a value in a processor determined from a value representing a signal.
- “Signal”, as used herein includes, but is not limited to one or more electrical signals, analog or digital signals, one or more computer instructions, a bit or bit stream, or the like.
- “Logic,” synonymous with “circuit” as used herein includes, but is not limited to hardware, firmware, software and/or combinations of each to perform a function(s) or an action(s). For example, based on a desired application or needs, logic may include a software controlled microprocessor or microcontroller, discrete logic, such as an application specific integrated circuit (ASIC) or other programmed logic device. Logic may also be fully embodied as software. The circuits identified and described herein may have many different configurations to perform the desired functions.
- The values identified in the detailed description are exemplary and they are determined as needed for a particular dispenser and/or refill design. Accordingly, the inventive concepts disclosed and claimed herein are not limited to the particular values or ranges of values used to describe the embodiments disclosed herein.

Electronics package 1120 includes apower supply 1134.Power supply 1134 may be any power supply, such as, for example, a plurality of batteries. Optionally,electronics package 1120 may be wired into an AC power source andpower supply 1134 may include a transformer.Power supply 1134 is in circuit communication with aircompressor drive circuitry 1126,refill selection circuitry 1130,actuator drive circuitry 1136,processor 1122 and any other circuitry that requires power. -
Processor 1122 is in circuit communication withmemory 1124.Memory 1124 may be any type of memory, such as, for example, Random Access Memory (RAM); Read Only Memory (ROM); programmable read-only memory (PROM), electrically programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), magnetic disk or tape, optically readable mediums including CD-ROM and DVD-ROM, or the like, or combinations of different types of memory. In some embodiments, thememory 1124 is separate from theprocessor 1122, and in some embodiments, thememory 1124 resides on or withinprocessor 1122. -
Processor 1122 is in circuit communication with refilllevel sensor circuitry 1140 that allowsprocessor 1122 to monitor the liquid level in the refill units (not shown). Although certain portions of “circuitry” are shown outside of theprocessor 1122, some or all of the circuitry may be contained in logic in theprocessor 1122 or onmemory 1124. As described above, the refill level sensor circuitry may include optical sensors, proximity sensors, floats, conductive sensors, weight sensors, or the like, and logic for providing an input toprocessor 1122. In some embodiments, conductive ink tracers extend down the dip tubes (not shown), or inside of refill bags (not shown). The conductive ink tracers may be used to provide a signal to theprocessor 1122. If there is fluid present in the refill bag, the fluid completes a circuit between two conductive ink tracers. If the circuit is broken, theprocessor 1124 may determine that the refill bag is empty. -
Processor 1122 is also in circuit communication withrefill selection circuitry 1130.Refill section circuitry 1130 is used byprocessor 1122 to select one refill unit to pump fluid out of until that refill unit is determined to be empty. If a refill unit is determined to be empty,refill selection circuitry 1130 causes the actuator to engage a second refill, andprocessor 1122 turns on anindicator 1106 to notify a user that a refill is empty and needs to be replaced. In some embodiments,refill selection circuitry 1130 is in circuit communication with adrive motor 1132 that repositions an actuator to operate the second refill unit. -
Processor 1122 is also in circuit communication withactuator drive circuitry 1136. Actuator drive circuitry is in circuit communication withdrive motor 1138 which moves the actuator to dispense fluid whenprocessor 1122 determines thatobject sensor 1104 has detected an object. Inaddition processor 1122 is in circuit communication with air compressor drive circuitry 1126 (in a foam dispensing system). Air compressor drive circuitry is in circuit communication withdrive motor 1128 which operates an air compressor (not shown) to mix air with liquid when thedispensing system 1100 is operated. Optionally, one drive motor may operate both the air compressor and the fluid pumps. - While the present invention has been illustrated by the description of embodiments thereof and while the embodiments have been described in considerable detail, it is not the intention of the applicants to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. Moreover, elements described with one embodiment may be readily adapted for use with other embodiments. Therefore, the invention, in its broader aspects, is not limited to the specific details, the representative apparatus and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the applicants' general inventive concept.
