## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims priority to and the benefit of Australian Provisional Patent Application No. 2020902547, filed Jul. 22, 2020, entitled “A DISPENSING DEVICE,” the disclosure of which is incorporated herein by reference in its entirety.
FIELD OF DISCLOSURE
The present disclosure relates to dispensing devices, systems, and methods for dispensing and storing a flowable substance.
BACKGROUND OF DISCLOSURE
Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
Drink mixes are added to hot or cold liquids to create flavoured beverages. Often, drink mixes are in liquid form, such as cordial, syrup, creamer, etc., or in powdered form such as powdered drink mix, instant coffee, TANG, KOOL-AID, hot chocolate, BEROCCA, medicinal powders, etc. While powdered drink mixes have typically been considered to be unhealthy, there has been some development in healthy vitamin-rich powdered drink mixes such as those that use vegetable and fruit powders.
To create a flavoured beverage, a recommended amount of drink mix is measured and dissolved with a recommended amount of liquid. This process is quite messy and time consuming for the user, and unfortunately, it is difficult to consistently measure and dose the recommended amount of drink mix, resulting in an inconsistent flavour profile between drinks. It would be advantageous if the drink mix was premeasured to ensure consistency.
Powdered and liquid drink mixes are stored separately to the liquid they are dissolved in. As such, drink mix beverages are difficult to transport unless they are pre-mixed, which can lead to an undesirable flavour profile and reduced freshness. Alternatively, a consumer may pack their drink mix and liquid separately, however this is inconvenient, and increases the number of items a consumer must carry. It would be advantageous if there were provided a convenient way to transport a drink mix and liquid together.
Preferably, drink mixes are stored in air-tight receptacles before being mixed with a liquid to ensure they maintain their freshness and potency. Unfortunately, it is not uncommon for the seal of most containers to be compromised, resulting in decreased freshness and potential spoilage of the drink mix before consumption.
Powdered drink mixes are generally not mixed with liquid until they are consumed. This can be due to a number of reasons. For example, powdered products with therapeutic benefits such as antibiotics, vitamins and minerals may be unstable or may lose their potency the longer they are exposed to a liquid. Further, based on the consistency and ingredients of the powdered drink mix, there is a likelihood that the powder will, over time, separate from the liquid creating small solid formations and an undesirable flavour profile. In the event that the powdered drink mix comprises components with nutrient value such as vegetable or fruit powder, there is an increased risk of spoilage if the powder is not sealed correctly before being mixed with the liquid. This is similarly the case for certain liquid drink mixes.

In some embodiments, the first unit and second unit are formed of polypropylene plastic (PP plastic) and the breakable seal is formed of low-density polyethylene plastic (LDPE plastic).
In various embodiments, a dispensing system, including a dispensing device, including the first unit and the second unit, and a receptacle, the dispensing device, and the receptacle may be manufactured and assembled together or separately.
For example, the dispensing device, including the first unit and the second unit, may be manufactured and assembled separately from the receptacle. In some examples, the first unit and the second unit are manufactured and then assembled with a flowable substance. The first unit and the second unit, storing the flowable substance, may later be assembled with the receptacle, which may contain a liquid, such as water.
The term “dispensing device” used herein refers to the first unit and the second unit, described in the figures below.
The term “dispensing system” used herein refers to a dispensing device and a receptacle.
The term “hermetically” used herein refers to an airtight seal of the dispensing device or system. For example, at least one of a protruding seal, a receptacle seal, and interfacing threaded portions in the disclosed technology hermetically seal a dispensing system and keep contents (e.g., food supplement powder stored in the dispensing device of the dispensing system and water stored in the receptacle of the dispensing system) inside the dispensing system stable for over 12 months.
The term “coupling mechanism” used herein refers to any mechanism that is able to couple components of the dispensing system. For example, the coupling mechanism may be complimentary threaded portions, channels and channel receiving portions, clips, friction fits, hinge mechanisms, etc.
The term “guide” used herein refers to text or a symbol that provides instruction to direct a user to apply a force.
Referring to FIG. 1, a dispensing system during a storage phase is shown. Specifically, a flowable substance (15) may be stored inside the dispensing system during the storage phase. The dispensing system includes a device is shown as received by a receptacle (2) in a first position. The dispensing device comprises a first unit (3) and a second unit (4).
The first unit (3) comprises an inner cylindrical projection (5) and an outer cylindrical projection (6) extending from a bottom face (50) of a top wall (7) of the first unit (3). The bottom edge or terminating end (16) of the inner cylindrical projection (5) is tapered in length. Specifically, the bottom edge or terminating end (16) of the inner cylindrical projection (5) is sloped downward from one side of the first unit (3) to the other side of the inner cylindrical projection (5) (also shown as bottom edge (16) in FIG. 3). As a result, one side (shown here as the left side of terminating end 16a) of the inner cylindrical projection (5) is shorter than the other side (shown here as the right side of terminating end 16b). In some embodiments, a portion of the bottom edge (16) may be shaped (as shown as shaped portion 30 in FIG. 5A and FIG. 5B).
In some embodiments, a portion or all of the bottom edge (16) of the inner cylindrical projection (5) may be linear or a jagged or sharp edge to perforate and cut or break a breakable seal (14) to open the first unit (3) for dispensing. The breakable seal may be formed of any material that is not permeable to air, such as foil, aluminium, metal, plastic, paper, lined paper etc. In some embodiments, the breakable seal (14) seal may be edible, soluble or biodegradable.
As shown in the embodiment in FIG. 1, where the left side of the inner cylindrical projection (5) is shorter than the right side of the inner cylindrical projection (5), in the first position, a small gap portion (42) is maintained between the terminating end (16) on the left side of the inner cylindrical projection (5) and a breakable seal (14). The gap portion (42) may be any size such that the opening of the inner cylindrical projection (5) does not break the breakable seal (14) until a force is applied to the top wall (7) of the dispensing device.
When the first unit (3) and the second unit (4) are assembled together, the first unit (3) may be received by the second unit (4) via a first coupling mechanism (13). The first coupling mechanism (13) comprises a raised collar portion (18) on the outer cylindrical projection (6) of the first unit (3), and a collar receiving portion (44a, 44b) on the outer cylinder (10) of the second unit (4), adapted to receive the raised collar portion of the first unit (3). In some embodiments, the collar receiving portion (44a, 44b) is a channel formed by a pair of circumferential projections formed in the inner face of the outer cylinder (10).
The collar receiving portion (44a, 44b) is a guide for when the first unit (3) is received by the second unit (4) in the first position and facilitates how far a user may initially push the first unit (3) into the second unit (4) in the first position without compromising the breakable seal (14), which occurs in a second position. The raised collar portion (18) “clicks” into place when it moves and is nestled into the collar receiving portion (44a, 44b). In use, an application of force to the top wall (7) of the first unit (3) can urge the collar portion from the collar receiving portion (44) into the second position and compromise the breakable seal.
In the first position, the outer cylindrical projection (6) of the first unit (3) may have a channel receiving portion (22) with a join opening (38) (shown and described in detail in FIG. 4b and in FIG. 4c). The channel receiving portion (22) may be located proximate and in between two protrusions of the broken raised collar portion (e.g., in between raised collar portion 18a and 18b in FIG. 4B) and adapted to receive a channel (23) located on the outer cylinder (10) of the second unit (4) via the join opening (38) in a second coupling mechanism.
The second coupling mechanism of the channel receiving portion (22) and the channel (23) is located on the shorter side (shown as the left side in FIG. 1) of the inner cylindrical projection (5), which is the portion of the terminating end (16) of the inner cylindrical projection (5) that does not come into contact with the breakable seal (14). The second coupling mechanism provides for a controlled and consistent motion to push the first unit (3) into the second unit (4) to break the breakable seal (14) with the opposing and longer side (shown as the right side in FIG. 1) of the terminating end (16) of the inner cylindrical projection (5). As a result, less pressure and effort are required by a user to break the breakable seal (14).
The breakable seal (14) is configured to close the opening of the inner cylinder (11) for preventing a flowable substance (15) stored in the dispensing device to be released into the receptacle (2). The right side of the inner cylindrical projection (5) is longer than the left side and is located proximate to or in contact with the breakable seal (14) without breaking the breakable seal (14) in the first position.
The flowable substance (15) can be stored within a chamber portion (54) formed by the inner cylindrical projection (5), inner cylinder (11), breakable seal (15) and top wall (7). The breakable seal (14) protects the flowable substance (15) from exposure to unwanted air that may enter via the inner cylindrical projection opening.
In the first position, the inner cylinder projection (5) of the first unit (3) is received by the inner cylindrical (11) of the second unit (4) such that the first and second protruding seals (8, 9) located on the inner cylindrical projection (5) bear on a portion of the inner face of the inner cylinder (11). The protruding seals (8, 9) ensure the chamber portion (54) is hermetically sealed such that excess air will not enter or escape from the chamber portion (54). The protruding seals (8, 9) located on the inner cylindrical projection (5), bear on a portion of the inner face of the inner cylinder (11) such that they are wedged against the inner face of the inner cylinder (11). An oxygen barrier is created at the location of the one or more protruding seals (8, 9) bearing on the inner cylinder (11). The protruding seals (8, 9) ensure the flowable substance (15) remains fresh in the chamber portion (54) for at least 12 months. In an embodiment with the dispensing device attached to a receptacle (2), the protruding seals (8, 9) ensure that the flowable substance (15) and water stored in the receptacle (2) remain stable.
The outer cylinder (10) of the second unit (4) is adapted to receive the receptacle (2) by way of complimentary threaded portions (34a, 34b) located on the outer cylinder (10) and receptacle (2) respectively. When interfaced, the threaded portions (34a and 34b) located on the outer cylinder (10) and receptacle (2) provide an air-tight enclosure such that no liquid is able to escape the receptacle (2) unless the receptacle (2) is uncoupled from the dispensing device.
The second unit (4) comprises an outer cylinder (10) and an inner cylinder (11) joined by a bridging portion (12). The bridging portion (12) is adapted to bear on an upper face (46) of the receptacle (2), and a receptacle seal (19) projecting from the bridging portion (12) bears on an inner face (48) of the receptacle (2) perpendicular to the upper face (46). An oxygen barrier is created at the locations of the bridging portion (12) bearing on an upper face (46) of the receptacle (2), and a receptacle seal (19) projecting from the bridging portion (12) bearing on an inner face (48) of the receptacle (2) perpendicular to the upper face (46). The receptacle seal (19) is also used to prevent water leaking from the receptacle (2). In an embodiment, increased pressure from inside the receptacle (2) causes the receptacle seal (19) to more greatly press against the inner face (48) of the receptacle (2), increasing the strength of the receptacle seal (19) and sealing inside the contents (17) of the receptacle (2).
The receptacle seal (19) may project from the bridging portion (12) continually or may be broken into numerous portions which project from the bridging portion (12). The receptacle seal (19) may be any shaped projection (e.g., triangular, circular, square, rectangular, etc.). The receptacle seal (19) may terminate in a chamfered or bevelled edge.
FIG. 2 depicts the dispensing system of FIG. 1 in a dispensing phase. Specifically, when a user desires access to the flowable substance stored in the dispensing device, the from the first position dispensing system is moved from the first position to a second position. In particular, an application of force has been applied to the top wall (7) of the first unit (3), lowering the inner cylindrical projection (5) into the inner cylinder (11), lowering the shorter side terminating end 16a of the inner cylindrical projection (5) into the gap portion (42) (not shown, as it has been decreased or eliminated), lowering the longer side terminating end 16b of the inner cylindrical projection (5) to contact and break the breakable seal (14), and releasing the flowable substance (15) into the receptacle (2).
A person skilled in the art would appreciate that disruption of the breakable seal (14) is understood to mean the breakable seal (14) is broken or torn, such that the flowable substance (15) is able to move passed the breakable seal (14) out of the chamber (54).
When the receptacle (2) is coupled to the dispensing device, the receptacle (2) is air-tight such that no liquid is able to escape the receptacle (2) unless uncoupled from the dispensing device. When the flowable substance (15) enters the receptacle (2) via the disruption of the breakable seal (14), the flowable substance (15) can be mixed with the contents (17) in the receptacle (2). In some embodiments, the mixing of the flowable substance (15) and the contents (17) is achieved by movement of the receptacle (2) and dispensing device, such as by shaking or swirling. In the event the flowable substance (15) is effervescent, no movement is required for mixing.
A person skilled in the art would appreciate that in another embodiment, the breakable seal (14) may fall into the receptacle (2) when the dispensing device is moved into the second position and there is disruption of the breakable seal (14). In some embodiments, the dispensing device may be not be coupled with the receptacle (2) or used without a receptacle (2). In such embodiments, the flowable substance (15) may be released into another desired location (e.g., directly into a drinking glass or) dispensed into the air and onto food on a plate).
In one embodiment, a portion of the breakable seal (14) may remain affixed to the inner cylinder (11) such that the breakable seal (14) does not fall into the receptacle (2) due to an affixing means which does not become broken when the dispensing device is moved into the second position. The affixing means may include part of the inner cylinder (11), a portion of the breakable seal (14) itself, or a connector (52), for example, as shown in FIGS. 1 and 2. The attachment of the connector (52) to the inner cylinder (11) and to the breakable seal (14) allows the flowable substance (15) to enter into the receptacle (2) yet allows the breakable seal (14) to remain fixed to the second unit (4). In some embodiments, when the first unit (3) is pushed down into the second unit (4) in the second position, the shorter side of the inner cylindrical projection (5) locates proximate to, but does not break, the connector (52) or the breakable seal (14), keeping a portion of the breakable seal (14) attached to the inner cylinder (11).
A person skilled in the art would appreciate that the connector (52) may be the use of thicker material, no perforations where other regions of the breakable seal (14) are perforated, etc. In some embodiments the affixing means may be part of the inner cylinder (11), part of the breakable seal (14), or its own individual component.
In some embodiments, the material of the breakable seal (14) is tapered in thickness from a center of the breakable seal towards the outer circumference of the seal (14) such that the material in or near the outer circumference of the breakable seal (14) is thinner than the material in the center of the breakable seal to ensure the inner cylindrical projection (5) is able to break the breakable seal (14). In some embodiments, the inner cylindrical projection (5) comprises a cut-away portion such that when there is an application of force to the top wall (7) of the first unit (3), the inner cylindrical projection (5) including at least a portion of the cut away portion is lowered into and beyond the gap portion (42) to break the breakable seal (14). However, the portion of the breakable seal (14) where the cut-away portion is lowered is not broken, such that the portion of the breakable seal (14) remains joined to the opening of the inner cylinder (11) and does not fall into the receptacle (2). This allows the flowable substance (15) to enter into the receptacle (2) yet allows the breakable seal (14) to remain fixed to the second unit (4).
In an embodiment, the breakable seal (14) may be joined to the dispensing device via a hinge mechanism or may be integrally joined to the second unit (4) via a heat seal or other joining means. The material of the breakable seal (14) may be tapered in thickness from a center towards a circumference of the seal (14), where the breakable seal (14) has a greater thickness in the center of the breakable seal (14) and a lesser thickness at the edges of the breakable seal (14) or may be the same thickness throughout. In an embodiment wherein the breakable seal (14) is joined to the dispensing device via a hinge mechanism, the hinge mechanism retains the breakable seal such the breakable seal (14) does not separate from the second unit (4).
The application of force to the top wall (7) of the first unit (3) urges the collar portion (18) from the collar receiving portion (44a, 44b) into the second position to compromise the breakable seal. The collar portion (18) is located outside of and proximate to the collar receiving portion (44a, 44b) in the second position.
In the second position, the channel receiving portion (22) has received the channel (23), and the channel (23) has moved further into the channel receiving portion (22). The channel receiving portion (22) and the channel (23) provide for a controlled and consistent motion to push the first unit (3) into the second unit (4) to break the breakable seal (14) in a second position. Also, as a result of the channel receiving portion and the channel, less pressure and effort may be required by a user to break the breakable seal (14).
In the second position, the protruding seals (8, 9) located on the inner cylindrical projection (5) are moved adjacent to and remain bearing on a portion of the inner face of the inner cylinder (11) such that they are wedged against the inner face of the inner cylinder (11). The oxygen barrier remains at the location of the one or more protruding seals (8, 9) bearing on the inner cylinder (11).
In the second position, the threaded portions (34a and 34b) located on the outer cylinder (10) and receptacle (2) maintain the air-tight enclosure such that no liquid is able to escape the receptacle (2) unless uncoupled from the dispensing device.

FIG. 3 illustrates a cross-sectional side view an embodiment of the first unit (3) in greater detail. In particular, the first unit (3) comprises a top wall (7) with an inner cylindrical projection (5) and an outer cylindrical projection (6) extending from a bottom face (50) of the top wall (7). A pair of protruding seals (8, 9) are located on the inner cylindrical projection (5) adapted to bear on the inner cylinder (11) of the second unit (4) such that they are wedged against the inner face of the inner cylinder (11). The second protruding seal (9) is located below the first protruding seal (8) towards the opening of the inner cylinder (11). The protruding seals (8, 9) ensure the chamber (54) is airtight such that excess air will not enter or escape from the chamber (54). An oxygen barrier is created at the location of the one or more protruding seals (8, 9) bearing on the inner cylinder (11). The seals ensure the flowable substance (15) (shown in FIG. 1 and in FIG. 2) remains fresh in the chamber for at least 12 months.
In the first position, a small gap portion (42) (shown in FIG. 1) is maintained between the terminating end (16) on the left side of the inner cylindrical projection (5) and a breakable seal (14) located to close the opening of the inner cylinder (11) for preventing a flowable substance (15) stored in the dispensing device to be released into the receptacle (2). As a result, the left side of the inner cylindrical projection (5) is shorter than the right side of the inner cylindrical projection (5). The right side of the inner cylindrical projection (5), longer than the left side, is located proximate to or in contact with the breakable seal (14) without breaking the breakable seal (14) in the first position (as shown in FIG. 1).
In some embodiments, when the first unit (3) is pushed down into the second unit (4) in the second position, the shorter side of the inner cylindrical projection (5) locates proximate to, but does not break, the connector (52) or the breakable seal (14), keeping a portion of the breakable seal (14) attached to the inner cylinder (11) (as shown in FIG. 2).
Referring to FIG. 3, the shorter side of the inner cylindrical projection (5) may be located toward a side of the first unit (3) where the channel receiving portion (22) with a join opening (38) (shown in FIG. 4b and in FIG. 4c) are located. The channel receiving portion (22) may be adapted to receive a channel (23) (shown in FIG. 6) located on the outer cylinder (10) of the second unit (4) via the join opening (38). The coupling mechanism of the channel receiving portion (22) and the channel (23) provide for a controlled and consistent motion to push the first unit (3) into the second unit (4) to break the breakable seal (14) in the second position. Less pressure and effort are required by a user to break the breakable seal (14) with the opposing right side of the inner cylindrical projection (5).
A raised collar portion (18) (shown in FIGS. 4a-c) is located on the outer cylindrical projection (6) of the first unit (3), which is adapted to be received by a collar receiving portion (44a, 44b) on the outer cylinder (10) of the second unit (4). In use, an application of force to the top wall (7) of the first unit (3) urges the collar portion from the collar receiving portion (44a, 44b).
FIGS. 4a, 4b, and 4c illustrate perspective views of an embodiment of the first unit (3). In particular, the first unit (3) comprises a top wall (7) with a guide. A guide may be text or a symbol that guides a user in how to operate the dispensing device (e.g., the words “PUSH” or “PRESS”). As shown here, the guide is embossed letters for the word “PUSH” located on the top face of the top wall (7) to direct where a user is to apply force to release the flowable substance (15) from the dispensing device. The inner cylindrical projection (5) and outer cylindrical projection (6) extend from the bottom face (50) of the top wall (7). A pair of protruding seals (8, 9) are located on the inner cylindrical projection (5) adapted to bear on the inner cylinder (11) of the second unit (4).
The outer cylindrical projection (6) comprises a broken raised collar portion (18) on its outer wall, wherein the broken raised collar portion (18) is formed of more than one collar portion running along the outer face of the outer cylindrical projection (6). For example, the broken raised collar portion (18) may comprise of multiple horizontal protrusions (shown in FIGS. 4a, 4b, and 4c as collar portions 18a, 18b, and 18c) extending outward from the outer face of the outer cylindrical projection (6). The broken raised collar portion (18) may have more than one single protrusion as the one single protrusion embodiment requires more pressure to break the breakable seal (14) as the dispensing device moves from a first position to a second position. The raised collar portion facilitates easier movement of the dispensing device from the first position to the second position to break the breakable seal (14).
In an embodiment, a channel receiving portion (22) may also be located on the outer face of the outer cylindrical projection (6). The channel receiving portion 22 may be located in between two protrusions of the broken raised collar portion (18) and adapted to receive a channel (23) located on the outer cylinder (10) of the second unit (4) (shown in FIG. 8c) via the join opening (38). The channel receiving portion and the channel provide for a controlled and consistent motion to push the first unit (3) into the second unit (4) from the first position to the second position to break the breakable seal (14). As a result of the channel receiving portion and the channel, less pressure and effort may be required by a user to break the breakable seal (14).
In some embodiments, the shorter side of the inner cylindrical projection (5) may be located toward a side of the first unit (3) where the channel receiving portion (22) with a join opening (38) are located, while the longer side of the inner cylindrical projection (5) is located opposite the channel receiving portion (22) and join opening (38). The location of the shorter side of the inner cylindrical projection (5) proximate the channel receiving portion (22) and join opening (38) and the longer side of the inner cylindrical projection (5) being located opposite the channel receiving portion (22) and join opening (38) further facilitates easier movement of the dispensing device from a first position to a second position.
