The embodiments relate to methods and devices for accurate dispensing, tracking, and reordering of dispensed fluids. Additionally, the embodiments relate generally to fluid dispensers, and more particularly to a fluid dispenser for a portable flexible package having an actuator configured for single-dose dispensing.
The technical problems addressed by the embodiments include: the delivery of information to users of fluids, ensuring that users of fluids use an accurate measurement(s) at the specified time, GPS location of fluid dispensing activity, accurate tracking of the time and dose, enable reminders for use and amount of the dosage to prevent overdose and to track compliance, and prompt for reorder to ensure ongoing compliance for which there is no current solution available, and communication of tracking information to the user, physicians, health care providers, retailers, manufacturers and others who wish to monitor usage, manage compliance, and reorder the fluid. Smart 1 TOUCH will integrate to electronic data collection, smart devices and audible data devices.
Additionally, various types of fluid material and media are employed for different purposes through commerce and industry. For example, there are various products in the personal care, home care, air care, transportation care, and food industries that require some type of dispensing of a fluid material from a source of such material. When this material is sold in commerce, it must be contained and stored in some type of container. When that product is used, it must be dispensed from its storage container to a location for use.
In the prior art, there are many different types of dispenses for delivering fluid material. For example, a flexible container body with a nozzle tip is commonly provided for such a purpose. An application of such use is for the dispensing of ketchup where the container body is squeezed by the user to urge the fluid material out from the nozzle tip and accurately to a desired location. The amount of fluid delivered is determined by how much the user squeezed the container body. However, this yields erratic results where more or less fluid material is delivered on each successive squeeze of the container body. Also, the container must be held upright to avoid leakage because no valves are employed.
In another example of a prior art dispensing device, a flexible container holds a volume of fluid material to be delivered. A single one-way check valve is provided as an exit port from the flexible container. When the flexible body is squeezed, the material is urged out under pressure through the valve.
The embodiments address the technical problems described above by either combining a mechanical measured fluid dispenser or sensor technology, such as Bluetooth or RFID, with hardware and software features that detect the time and amount of a fluid dispensing operation, and communicate that information to a user's smart phone app or software which can then optionally, and preferably according to a user-selection, communicate that information to the user's physician, pharmacy, retailers, manufacturers or other interested parties requiring compliance, monitoring and reordering capabilities.
According to various embodiments, the mechanical or sensor based measured fluid dispenser may be of the type disclosed in, for example, U.S. Pat. Nos. 8,123,073, 7,419,322, 8,387,833, 10,259,645, 10,654,059, 10,160,587 and/or 11,008,156, the disclosures of each of which are incorporated herein by reference in their entirety.

The sensor may be any single sensor or combination of sensors that provide information concerning the amount of fluid that is dispensed upon the activation of the dispenser's actuator. Accordingly, the sensor may be located inside or beneath the actuator itself, located somewhere in the fluid channel/pathway, or in dispenser case enclosures.
According to another embodiment, the mechanical measured dispenser may include an adjustable dose mechanism according to which the amount of the dose may be adjusted by the user. According to a further feature of this embodiment, one or more sensors may be provided to determine the adjustment state of the adjustable dose feature.

The features of the embodiments are set forth with particularity in the appended claims. The figures are for illustration purposes only and are not drawn to scale. The embodiments, however, both as to organization and method of operation, may best be understood by reference to the detailed description which follows taken in conjunction with the accompanying drawings in which:
In describing the embodiments, reference will be made herein to
The embodiments are directed to a device for dispensing fluid from a pouch, the device capable of being set to different discrete and repeatable/equal dispensing amounts, depending on the amount of fluid required to be dispensed by the user for various applications and uses. The device may also be set to an “off” or “closed” position to prevent accidental dispensing of fluid when not in use. The device is preferably configured to be affixed to the outer surface of a fluid container 50, which fluid container is preferably a flexible bag or pouch, though portions of dispensing device may be situated inside or outside the fluid container 50, provided that dosing dome 2 or button 1 is accessible from the outside of the flexible container for actuation by the user. According to various embodiments, at least one surface of the fluid container 50 or a sufficient portion of the fluid container 50 is flexible to allow the container to collapse as fluid is withdrawn therefrom. In the case that the entire fluid container 50 is not made of flexible material, the dispensing device is preferably attached to portion of the container 50 that is flexible and which is collapsible as fluid is dispensed from the container 50.
The device also includes one or more sensors 20 configured to record, store and/or transmit one or more physical properties of the device, particularly when the dispensing device is actuated in order to dispense fluid and/or when the device is adjusted to a particular dose.

Additional nonlimiting features of the pump or dosing chamber that may be utilized for the fluid dispensing device of the embodiments shown in
Referring to
In use, a user operates dispensing assembly 110 to draw fluid from inside of flexible pouch 102 and to dispense an amount of the fluid that has been drawn into dispensing assembly 110, all as further described below.
Dispensing assembly 110 includes a pump chamber 120 and a fluid exit channel 130 in fluid communication with the pump chamber 120. As discussed in further detail below, pump chamber 120 serves as an intermediate chamber to pull a volume of fluid into dispensing assembly 110, and fluid exit channel 130 serves to deliver a portion of such volume of fluid from pump chamber 120 to the outside of fluid dispenser 100.
Pump chamber 120 includes a pump chamber inlet 121 that opens at one end to an interior of flexible pouch 102, and opens at the opposite end into the interior of pump chamber 120. Ultimately, a portion of the fluid that is drawn into the interior of pump chamber 120 from the interior of flexible pouch 102 is delivered to fluid exit channel 130 through fluid outlet 122 from pump chamber 120.
In order to draw fluid into pump chamber 120 and to push a portion of such fluid downstream to fluid exit channel 130, a flexible actuator 123 is provided having a depressible bulb 124 that may be engaged by a user's finger when they wish to dispense a volume of fluid from fluid dispensing 100, which dispensing operation will be discussed in greater detail below. Flexible actuator 123 may be formed of a variety of flexible materials, such as (by way of non-limiting example) a thermoplastic polyolefin elastomer. A suitable and exemplary thermoplastic polyolefin elastomer material is readily commercially available from The Dow Chemical Company under the name ENGAGE™ 8401. Flexible actuator 123 also includes a raised circumferential wall 125 that encircles depressible bulb 124, with a bottom-most portion of depressible bulb 124 being attached to a bottom, interior edge of circumferential wall 125. When a user engages flexible actuator to dispense a volume of fluid from fluid dispenser 100, depressible bulb 124 deforms from a concave structure to a convex structure (as it is pushed downward into the body of pump chamber 120), while raised circumferential wall 125 generally maintains its shape.
A thin cover 126 may optionally be positioned over pump chamber inlet 121, and is preferably formed of a thin, flexible film that is affixed at one end to an interior of pump chamber 120, and is not fixed at the other end which is in turn positioned over pump chamber inlet 121. Thus, thin cover 126 may freely move with respect to pump chamber inlet 121 to allow fluid to flow from the interior of pouch 102 to the interior of pump chamber 120, and likewise from pump chamber 120 back to the interior of pouch 102, depending upon the position of flexible actuator 123 (as discussed in greater detail below).
Alternatively, or in addition to thin cover 126, a pump chamber inlet closure 127 may be provided and positioned over pump chamber inlet 121, movable from an open position (allowing fluid to flow from the interior of flexible pouch 102 to an interior of pump chamber 120, and vice versa) to a closed position (preventing fluid from flowing from the interior of flexible pouch 102 to an interior of pump chamber 120, and vice versa). Pump chamber inlet closure 127 is attached at one end to preferably the bottom-most portion of circumferential wall 125, which point of attachment creates a hinge allowing the remaining portion of closure 127 to move between its open and closed positions. Pump chamber inlet closure is preferably formed of the same material as flexible actuator 123, and is likewise preferably integrally formed therewith. Preferably, in an at-rest position, but after a user has at least initially pumped flexible actuator 123 so as to prime dispensing assembly 110 with a volume of fluid, a slight gap exists between the bottom surface of pump chamber inlet closure 127 and the top of pump chamber inlet 121. Likewise, when at rest, a very slight gap between such thin film inlet cover 126 and the top of pump chamber inlet 121—only a slight gap is necessary at this stage to allow bi-directional flow between the interior of pump chamber 120 and the interior of flexible pouch 102. Pump chamber inlet closure 127 is configured to (as discussed in greater detail below) flex downwardly and press against thin film inlet cover 126 (if present) at a point during the downward stroke of flexible actuator 123, thus pressing itself against the top portion of pump chamber inlet 121, or pressing thin film inlet cover 126, if present, against the top portion of pump chamber inlet 121, and preventing flow between the interior of pump chamber 120 and the interior of flexible pouch 102. If chamber inlet closure 127 is not present, and only thin film inlet cover 126 is present, the downward stroke of flexible actuator 123 causes thin inlet cover 126 to press against the top portion of pump chamber inlet 121, preventing flow between the interior of pump chamber 120 and the interior of flexible pouch 102.
As mentioned briefly above, fluid exit channel 130 is in fluid communication with pump chamber 120. Fluid exit channel 130 includes an intermediate chamber 131 and an outlet channel 132. Intermediate chamber 131 opens at one end into pump chamber 120, and at the opposite end to outlet channel 132. The opposite end of outlet channel 132 comprises fluid outlet 133 from which fluid exits fluid dispenser 100. A flange is positioned around the base of circumferential wall 125 of flexible actuator 123, and a portion of the flange is extended in flexible flange extension 128. Flexible flange extension 128 is positioned over intermediate chamber 131 and, in the at-rest position shown in
A movable cap 140 may be provided at the end of fluid exit channel 130 and is preferably hinged thereto, such that movable cap 140 may be selectively positioned over fluid outlet 133 to close the same, or may be pivoted to the open position shown in
Next, and with regard to
Next, as shown in
Next, and as shown in
Next, and with reference to
During this process, flexible flange extension 128 of flexible actuator 123 is preferably in its at-rest position (collapsed against intermediate chamber 131), thus limiting the flow of fluid from outlet channel 132 back toward pump chamber 120. Likewise during this process, pump chamber inlet closure 127 begins to lift off of pump chamber inlet 121, in turn allowing thin film inlet cover 126 to lift off of pump chamber inlet 121 so as to allow fluid to begin flowing into the interior of pump chamber 120 from the interior of flexible pouch 102.
According to a particular and unexpected advantage of the embodiments, due to the fact that fluid passage 131 and flexible flange extension 128 are situated inside of the flexible pouch, large amounts of pressure may be applied to flexible pouch 102 without causing the unintended escape of fluid from the dispensing assembly because any pressure applied to flexible pouch 102 will translate to the outside of flexible flange extension 128, sealing it against bottom portion of fluid passage 131 and preventing the movement of fluid. Indeed, the more pressure that is applied to flexible pouch 102, the more tightly that flexible flange extension 128 is pressed against the bottom of fluid passage 131. This represents a significant advantage over prior art dispensing devices in which a sufficient amount of pressure applied, intentionally or unintentionally, to the flexible pouch would cause one or more valves to reverse or otherwise fail, causing liquid to unintentionally exit the dispensing device, potentially resulting in the ruin or soiling of neighboring fabrics and other materials.
Next, and as shown in
With regard to further aspects of an embodiment, and with reference to
As shown in
Similarly, and as shown in
As still another alternative to prevent back flow of fluid from a container with which the contents of flexible pouch 102 are to be mixed, and as shown in
