In some embodiments, a system for dispensing liquid from a container holding a liquid comprises a reservoir mountable to the container so as to be in fluidic communication with the container. The reservoir may comprise an inlet and an outlet. When mounted to the container, the reservoir may be configured to measure a predetermined quantity of liquid while in first orientation and to simultaneously dispense the predetermined quantity of liquid from the outlet and receive a refilling quantity of liquid through the inlet while in a second orientation that is angled relative to the first orientation above a threshold angle.

A fine grain powder metering unit for fine-grained powders combines the volumetric metering mode with the weighing mode, using for pre-metering 95-99% of the required quantity a volumetric drawer which is then emptied into the tray of a precision scale where a low-flow feeder feeds the powder for metering the final 1-5%, so as to combine the advantages of both metering modes and quickly achieve a metering with high accuracy and repeatability, automatically and with a simple and reliable structure.

Aspects of the present invention are directed to a variable dose applicator. The variable dose applicator comprises a container including a collar portion, a top portion, a bottom portion, and a side wall portion, the space between the bottom portion and the side wall portion defining an interior space to hold contents of the container. The variable dose applicator may further include an actuator, the actuator being depressible in a longitudinal direction to drive the contents held in the interior space of the container out of an applicator extending from the actuator. Additionally, the actuator includes one or more dosing elements protruding horizontally from the actuator. The collar portion has a top circumferential edge containing one or more grooves of varying depth into which the one or more dosing elements can be inserted when the actuator is depressed, thereby adjusting a distance the actuator is moved in the longitudinal direction.

A squeeze doser with a childproof cap is described herein. The squeeze doser with a childproof cap includes a container, a reservoir, and a cap. The container includes a neck. A reservoir is coupled with the neck of the container, wherein the reservoir further comprises a spout and at least one notch located on an outer surface of the neck, said spout coupled with a fill tube that guides liquid stored in the container to the spout, the spout including one or more holes positioned to maintain a predetermined dosage of liquid within the reservoir. The cap is releaseably attached to the neck and includes at least one protrusion that is configured to mate with the at least one notch of the neck, whereby the at least one protrusion coupled with the at least one notch renders the container childproof.

A digital dispense system and method for analyzing samples. The system includes a fluid droplet ejection system housed in a compact housing unit. The fluid droplet ejection system contains a fluid droplet ejection head and fluid cartridge containing one or more fluids to be dispensed, a cartridge translation mechanism for moving the fluid droplet ejection head and fluid cartridge back and forth over a sample holder in an x direction; and a sample holder translation mechanism for moving a sample back and forth beneath the fluid droplet ejection head and fluid cartridge in a y direction orthogonal to the x direction. A digital display device is attached to the fluid droplet ejection system for displaying fluid volume information to a user. The fluid volume information is selected from relative fluid volume, absolute fluid volume, and a combination of relative and absolute fluid volumes.

A measuring a closed-loop fluid transfer system is provided that includes a measuring adapter having a first end and a second ends, and a chamber located there between and configured to hold a volume of fluid. The measuring adapter includes a first receiving valve assembly located at the first end of the measuring adapter. The first receiving valve assembly includes a receiving valve member, at least a portion of which is separable from a portion of the first receiving valve assembly. This creates an opening that provides fluid communication to the chamber when a force is exerted on the receiving valve member of the first receiving valve assembly. A second valve assembly located at the second end of the measuring adapter includes a valve member. At least a portion of the valve member of the second valve assembly is separable from a portion of the second valve assembly to create an opening that provides fluid communication to the chamber.

A dispensing device for dispensing material. The dispensing device comprises a dispensing head; a capsule magazine including at least one void; at least one material capsule, wherein the at least one material capsule is disposed within the at least one void in the material capsule magazine; a motor, operable to provide mechanical power for material dispensing operations, wherein the motor is disposed within the dispensing head; and a gear mechanically connected to the motor, wherein the gear is further disposed in connection with the at least one material capsule, such that operation of the motor causes rotation of the gear and, in turn rotation of the at least one material capsule.

A counting mechanism (100) for a dispenser comprising: a first and a second housing part (110, 120) that are rotatable relative to each other; and a counting ring (130) disposed between the housing parts. The first housing part has a protrusion (111) which abuts the counting ring, holding a portion of the counting ring in contact with the second housing part. The relative rotation of the housing parts causes the protrusion to slide against the surface of the counting ring to drive a rolling movement of the counting ring around the circumference of the second housing part, such that a predefined rotation of the housing parts produces an incremental rotational displacement between the counting ring and second housing part to record a count. The counting mechanism provides a large gear reduction ratio in a compact form which is straightforward to manufacture and provides an accurate and reliable record of counts.

An apparatus for dispensing a towel and/or a liquid, which stores information pertaining to an amount of the towel and/or liquid that is arranged in the apparatus and/or dispensed by the apparatus. The apparatus stores the information in a control data memory that is able to be written to only once. The control data memory is part of a radio chip. The apparatus stores the information pertaining to the dispensed amount in a comparison data memory that is erasable and rewritable. The apparatus automatically compares the information pertaining to the dispensed amount of the towel and/or liquid that is stored in the control data memory and in the comparison data memory with one another. The apparatus prevents the towel and/or liquid from being dispensed, or stores the information pertaining to the amount that is stored in the control data memory in the comparison data memory, if the information of the control data memory and that of the comparison data memory are not consistent with one another.
