GOJO Industries Inc. and Zosimadis | Date: 2017-02-15

An energy storage device, like for example a supercapacitor, is used to provide power to activate a motor for dispensing a dosed amount of hand care product. The energy storage device or supercapacitor is recharged from an energy supply source, e.g. batteries, integrated into the replaceable refill reservoir and/or mounted into the dispenser housing. A controller directs energy discharged from the energy supply source(s) at one of a plurality of discharge energy rates for recharging the energy storage device. Depending on the number of dispense events that occur with a given time interval, the controller may vary the rate at which the energy is discharged from the energy supply source(s) to recharge the energy storage device.

A dispensing system comprises a first electronic sensor and a controller. The first electronic sensor may be configured to detect a first change from a first amount of a fluid product in a dispensing system reservoir to a second amount of the fluid product in the dispensing system reservoir. The controller may be coupled to the first electronic sensor and configured to receive a first signal from the first electronic sensor indicative of the first change. The dispensing system reservoir may be disposed in the dispensing system. A method for determining a remaining service interval for a dispensing system reservoir is also provided.

One or more techniques and/or systems are provided for personal tracking of hygiene compliance of a user. For example, a mobile device may host a tracking component (e.g., a personal hygiene compliance app deployed on a cell phone or tablet). The tracking component may be configured to establish a communication connection, such as a Bluetooth communication connect, with a hygiene device (e.g., a soap dispenser). The tracking component may generate either a hygiene compliance metric or a non-hygiene compliance metric based upon whether a dispense event notification, indicating compliance by the user with a hygiene opportunity, is received from the hygiene device. In this way, the user may personally track hygiene compliance information based upon automated communication signals shared between the mobile device and the hygiene device.

A dispensing system includes a container within which a material is contained. The dispensing system includes a nozzle, attached to the container, having a first portion and a second portion. The dispensing system includes a magnet attached to the first portion and a compliance system attached to the second portion. The compliance system includes a transmitter and a magnet sensor, coupled to the transmitter, for detecting a presence of the magnet when the first portion with respect to the second portion is in a closed position, and for detecting a non-presence of the magnet when the first portion with respect to the second portion is in an opened position. The transmitter transmits a wireless compliance signal indicative of the magnet sensor detecting at least one of the presence or the non-presence of the magnet.


Exemplary embodiments of dispensers and refill units are disclosed herein. An exemplary refill unit for a soap, sanitizer or lotion includes a non-collapsing container. The non-collapsing container includes a neck. An annular projection is located at least partially on the neck. A one-way valve is located proximate the annular projection. The one-way valve allows air to flow into the non-collapsing container once the vacuum pressure in the container reaches the cracking pressure of the one-way valve and the one-way valve prevents liquid from flowing out of the annular projection. In addition, a pump for pumping the contents of the container out of the container is also included.


Exemplary dispensers, pumps and refill units are disclosed herein. An exemplary refill unit includes a container and a foam pump. The foam pump includes a liquid pump chamber, a compressible air inlet chamber and a compressed air inlet. The volume of the compressible air inlet chamber is less than the volume of air used to make a dose of foam. A one-way air inlet valve is located proximate the compressed air inlet. A piston is included that is movable within the liquid pump chamber and has a liquid seal member and an air seal member. The liquid pump chamber includes a liquid outlet into a center portion of the piston. One or more openings extend through the piston wall and provide a passage from the compressible air chamber to the center portion of the piston. The pump further includes mix media and an outlet.

Exemplary embodiments of vented refill units and dispensers having vented refill units are disclosed herein. An exemplary refill unit includes a non-collapsing inverted container. The container has a neck located at the bottom of the container. A pump is secured to the neck. The pump has a housing that has a cylindrical outside surface. In addition, the housing has an attachment mechanism for attaching the pump to a venting insert. The venting insert has a cylindrical inside surface and a cylindrical outside surface. At least a portion of the venting insert is located within the neck. An air passage is located between the pump housing and the cylindrical inside surface of the venting insert. One or more apertures are located through the venting insert. A one-way air inlet valve is located proximate the one or more apertures.


A method and device for indicating whether a dispensable product will require refilling prior to the next scheduled service interval includes tracking the amount of use over a first interval, and calculating a frequency based from the use over the first interval. The quantity remaining is compared with the required amount, which is the product of the number of weeks in the service interval and the calculated frequency. Thus, when the quantity remaining is less that the required amount, a warning will be provided to indicate that the dispensing product should be replaced, as it will be empty before the next service interval.

Among other things, one or more systems and/or techniques for improving performance of a dispensing system are provided herein. The dispensing system may comprise an emitter and a detector. The emitter may be configured to transmit light (e.g., and/or one or more other signals). The detector may be configured to measure light, for example. The detector may determine a first measurement of light while the emitter is not transmitting light. The detector may determine a second measurement of light responsive to the emitter transmitting light. The detector may determine a third measurement of light based upon a comparison of the first measurement of light with the second measurement of light. The detector may be direct current (DC) coupled while determining the third measurement of light.


Hand sanitizers are provided with improved aesthetics and skin-conditioning effects, such that healthcare workers and others subject to high frequency hand hygiene requirements are encouraged to comply with said requirements. The hand sanitizers provide excellent antimicrobial efficacy and skin conditioning benefits that actually increase with increased frequency of use. The sanitizing compositions are hydroalcoholic, and contain a synergistic combination of skin-conditioning agents.
