A fluid dispensing system comprises a frame to hold first and second fluid containers in stacked relationship. The fluid dispenser dispenses e.g. milk from a container 26 that can be inserted in a first compartment 22 of a frame 20. A second container can be inserted in a lower compartment 24. The container 26 includes a tap 30 for dispense and the frame 20 has a cut out portion to receive the tap. Once the first container is empty, the frame may be inverted and fluid from the second container dispensed. The frame is dimensioned to fit e.g. in the door of a domestic refrigerator and arranged such that the tap 30 is accessible above a retaining bar (16, figure 1) that holds the frame in the door.

Description

FLUID DISPENSING SYSTEM

FIELD OF THE INVENTION

This invention relates to a fluid dispensing system, particularly to a dispensing tap, to storage frame and to a fluid container for use in a fluid dispensing system.

BACKGROUND OF THE INVENTION

Many fluids, such as milk, water, fruit juices and soft drinks, are supplied in disposable containers adapted to be stored, for example, in a refrigerator.

Whilst these containers are convenient for many people, they do pose problems for people with conditions such as arthritis or people suffering from disabilities such as blindness. For example, these packages can be difficult to open and can be difficult to manipulate to ensure the correct amount of liquid is poured out.

These problems are compounded by the fact that it is often more cost effective for a consumer to purchase milk or juice in large volume containers, such as 2 or 3 litres. These larger containers are especially difficult to manipulate during use, and when stored in a fridge door can be difficult to lift over the retaining bar provided on the door to secure products on the door shelf.

A further drawback with containers housing large volumes of, for example, milk is that the shelf life of the product is relatively limited and a user may not be able to finish the product before it starts to go off.

It is known to supply products, for example wine, in boxes with dispensing taps. However, these products are designed for dispensing from the edge of a table or whilst being held and are not suitable for dispensing direct from a refrigerator, particularly from the door of a refrigerator where the retaining bar will be a problem.

It is an object of at least one embodiment of the present invention to mitigate or obviate at least one

problem associated with the prior art.

SUMMARY OF THE INVENTION

According to a first aspect of the present invention there is provided a fluid dispensing system comprising: a frame defining a first compartment adapted to receive a first fluid container, and a second compartment adapted to receive a second fluid container, the first and second compartments being in a stacked relationship; and at least one dispensing tap adapted to selectively permit fluid to be dispensed from at least one of the first and second containers when located in a respective compartment.

The fluid dispensing system as described above permits fluid to be dispensed from a location, for example a fridge, without the need for removal of the fluid container and further permits one container to be in use, whilst a second container is, for example, being chilled.

Preferably, the fluid dispensing system is arranged such that it is only possible to dispense fluid from the upper of the two compartments. Having an arrangement where the fluid can only be dispensed from the upper of the two compartments provides a system in which the fluid container from which fluid is to be dispensed is raised.

This means the fluid dispensing system can be used in situ, for example in the door of a refrigerator where there is often a retaining bar or the like which can prevent conventional dispensing systems, such as a wine box, being used without being removed from the door. The fluid dispensing system is also adapted to be useable from, for example, the centre of a table or away from the edge of a work surface.

Preferably, the frame can be arranged in a first orientation in which the first compartment is above the second compartment or in a second orientation in which the second compartment is above the first compartment.

Once a fluid container in the first compartment is empty, the fluid dispensing system can be removed, for example from the f ridge door, inverted and put back into the door. Chilled fluid can then be dispensed from the second fluid container.

Preferably, the first and second compartments are identical.

Preferably, the fluid dispensing system further comprises at least one fluid container located in the first and/or second compartments.

Preferably, the/each dispensing tap is integral with a fluid container.

Most preferably, the/each fluid container comprises a fluid storage portion and a dispensing tap.

Preferably, the/each dispensing tap is located in an opening defined by the respective compartment.

Where there are two dispensing taps, the dispensing taps may be adjacent one another.

In one embodiment, the dispensing taps are located in a horizontal plane, the horizontal plane being located at or adjacent the midpoint of the frame. Having the dispensing taps adjacent and on the same horizontal plane provides a system in which a user can conveniently locate the taps and decide which tap is to be used.

Preferably, the frame includes engaging means to releasably engage a fluid container.

Preferably, the engaging means is integrally moulded to the frame. Most preferably, the engaging means is a snap fit. The snap fit may be a cooperation between the frame and a dispensing tap. A snap fit is a convenient, low cost method of securing the fluid container in the frame.

Preferably, the first and second compartments have an internal profile adapted to guide the at least one fluid container into the engaging means.

Preferably, each compartment defines an access aperture for the insertion and removal of the fluid container. Each access aperture may be located at an end of the respective fluid compartment distal the horizontal plane. Alternatively, the access apertures are located on the back or side of the frame. A system in which the fluid containers are removable is particularly desirable.

Once a fluid container is empty, the fluid dispensing system can be inverted so that the full chilled container is in the upper compartment and the empty container is in the lower compartment. Once the user has purchased a replacement container, the empty container can be removed and the new container inserted into the lower compartment for pre-use chilling. This process can be repeated to ensure a continuous supply of chilled liquid which can be conveniently dispensed from a refrigerator.

Preferably, the access apertures are of sufficient size to permit a user to insert a hand to remove an empty fluid container or to check the contents of a fluid container.

Preferably, the/each dispensing tap extends from the front of the frame.

Preferably, the internal profile of the first and second compartments are arranged to orient the/each tap in a sloped orientation with respect to the frame, such that the tap associated with the upper fluid container slopes downwards from the back of the frame towards the front and the tap associated with the lower fluid container slopes upwards from the back of the frame towards the front. Such an arrangement, in which the taps slope from the back of the frame towards the front in different directions, is useful to the partially-sighted person who can tell by feeling the slope of the taps which tap they should line their cup or bowl up with to obtain milk. Furthermore, having the tap in the upper compartment, that is the compartment which is in-use, results in an improved flow rate.

Preferably, each dispensing tap comprises a housing defining a fluid inlet and a fluid outlet, a valve element for selectively sealing the inlet and outlet and a venting means; wherein the valve element is actuatable between a zero flow position in which the inlet is open and the outlet is closed, a dose position in which the inlet is closed and the outlet is open and a continuous flow position in which both the inlet and outlet are open. A partially sighted person can have difficulties in judging the correct amount of, for example, milk to whiten a cup of tea. A tap of this type is particularly useful as it permits either a metered dose of liquid to be dispensed, suitable for example, for milking a cup of tea or a continuous flow of fluid to be dispensed, for example when pouring milk onto cereal.

Incorporating a vented valve in the tap has a significant advantage when used with product stored in, for example, a sealed bag in that the product will not need to be in contact with air. This is because the air vent will only be required when a dose is being dispensed, a position in which the inlet between the fluid container and the tap is closed. As the liquid contained within the fluid storage portion is not exposed to the environment, the shelf life of the product can be extended, as compared to product exposed continually to air. Preliminary experiments indicate that using a vented tap with a sealed bag can extend the shelf life of milk by as much as four days.

Preferably, the valve element is rotatable with respect to the housing between the zero flow, dose and continuous flow positions.

Preferably, to move the valve element from the zero flow position to the dose position, the valve element is actuated in a first direction, and to move the valve element from the zero flow position to the continuous flow position, the valve element is actuated in a second, opposite direction. Utilising opposite directions for the dosing and continuous flow positions provides an intuitive system in which less dexterity is required to obtain the desired result.

Preferably, the valve element is manually actuated.

Most preferably, the valve element is actuated by a lever.

Preferably, the valve element and the lever are connected by a shaft, the valve element and the lever being fixed to the shaft such that rotation of the lever results in an equal rotation of the valve element.

Alternatively, a small actuation of the lever may result in a larger actuation of the valve element.

Preferably, the housing is cylindrical and has an internal surface.

Preferably, the valve element includes an inlet sealing portion, an outlet sealing portion and at least one support portion.

The inlet sealing portion and the outlet sealing portion may be two separate components. Where the inlet sealing portion and the outlet sealing portion are two separate components, preferably both components are fixedly mounted to the shaft. Using separate portions for the inlet sealing and the outlet sealing allows the valve element to be of minimal volume. As the dose of fluid delivered by the tap is defined by the tap housing, the less space within the tap housing that the valve element occupies the better, as it is desirable to have a small a tap as is practically possible.

Preferably, the at least one support portion is adapted to resist, in use, forces applied to the inlet sealing portion to maintain an inlet seal and/or the outlet sealing portion to maintain an outlet seal.

Preferably, the/each support portion engages an internal surface of the housing.

Preferably, the inlet sealing portion has an integral support portion. Most preferably, the integral support portion engages the internal housing surface opposed to the housing inlet. When the fluid container is full, significant pressure may be applied to the tap inlet portion which could result in leakage. The positioning of the integral support portion ensures a tight seal is maintained between the inlet sealing portion and the housing around the inlet.

Preferably, the venting means comprises a one-way valve. Most preferably, the venting means is a duckbill valve.

Preferably, the tap further comprises a locking means to lock the valve element with respect to the housing and to prevent leakage through the fluid outlet prior to the first use. The locking means may also be adapted to indicate whether or not the tap has been tampered with.

Preferably, the locking means engages the valve element and the housing.

Preferably, the locking means includes a profiled gripping portion. The profile may be in the form of Braille.

Preferably, the valve element is biased to the zero flow position. Most preferably, the tap further includes a spring to bias the valve element to the zero flow position. Biasing the valve element to the zero flow position reduces the possibility of accidents.

Preferably, the spring is a torsion spring acting on the housing and the lever.

Preferably, the housing and the valve element are ceramic. Utilising ceramic for the housing and the valve element provides for a reusable, seal-less system.

Alternatively, the housing and the valve element could be polymeric or metal. A polymeric housing and valve element will be lower cost to manufacture but may require the additional provision of seals. Metal provides for improved tolerances over some other materials and is capable of withstanding high sterilisation temperatures.

Preferably, the tap includes indicator means to indicate when the lever has been actuated to the dose position or the continuous flow position from the zero flow position.

Preferably, the indicator means is in the form of at least one abutment located on the housing.

Preferably, there is one abutment and the outlet valve portion engages the abutment in the dose position and the continuous flow position.

Preferably, each fluid storing portion is flexible.

Most preferably, each fluid storing portion comprises a flexible bag. Preferably, the flexible bag is LDPE. In a preferred embodiment the flexible bag is blow moulded from L]JPE. Blow moulded L]JPE bags are simple and easy to manufacture, and can be recycled.

Preferably, the tap is retained within a tube which is attached to the flexible bag. The tap may be retained within the tube by shrink wrapping.

Preferably, each fluid container includes a support card. A support card is useful with a flexible bag to provide support for the bag when located in a frame compartment.

Preferably, the support card can be used to carry information and/or advertising.

Preferably, the dispensing system is sized to fit in the door of a refrigerator.

According to a second aspect of the present invention there is provided a frame for use in the first aspect.

According to a third aspect of the present invention there is provided a dispensing tap for dispensing a fluid, the dispensing tap comprising: a housing defining a fluid inlet and a fluid outlet; a valve element for selectively sealing the inlet or outlet; and a venting means; wherein the valve element is actuatable between a zero flow position in which the inlet is open and the outlet is closed, a dose position in which the inlet is closed and the outlet is open and a continuous flow position in which both the inlet and outlet are open.

According to a fourth aspect of the present invention there is provided a fluid container adapted for use in the fluid dispensing system of the first aspect.

According to a fifth aspect of the present invention there is provided a fluid container comprising the dispensing tap of the third aspect.

By virtue of the present invention a fluid dispensing system can be provided which facilitates the dispensing of a liquid by a user either in a metered dose or a continuous flow with equal ease of use.

DETAILED DESCRIPTION OF THE INVENTION

Referring firstly to Figures 1, 2a and 2b, there is shown a figurative perspective of a fluid dispensing system, generally indicated by reference numeral 10, in use, according to an embodiment of the present invention.

The fluid dispensing system 10 contains milk and is shown located in its normal storage position in the door 12 of a refrigerator 14. The door 12 includes a restraining bar 16 for preventing food and drink items from falling out of the door 12 as it is opened and closed. The fluid dispensing system 10 can be easily operated, that is milk can be dispensed, without the system 10 needing to be removed from the f ridge door 12. The fluid dispensing system 10 is designed such that milk can be dispensed either in a metered dose, for example sufficient to whiten a cup of tea, or continuously, for example to fill a jug or milk breakfast cereal.

The fluid dispensing system 10 comprises a frame 20, the features of which, along with the additional system features can be seen more clearly in Figures 2a and 2b.

Figures 2a and 2b show isometric views of a replacement fluid container 26 prior to insertion (Figure 2a), and inserted (Figure 2b) , in the frame 20 of the fluid dispensing system 10 of Figure 1.

The frame 20 defines a first compartment 22 and a second compartment 24. Each compartment 22,24 is adapted to receive a fluid container 26. For clarity only one fluid container 26 is shown. The first compartment 22 is directly above the second compartment 24. This arrangement permits the fluid container 26 in the first compartment to be raised sufficiently to allow milk to be dispensed over the retaining bar 16 whilst the fluid dispensing system 10 is located in the f ridge door 12, or if it is removed from the f ridge door 12, to allow milk to be dispensed whilst sitting in the middle of a table or away from the edge of a work surface This arrangement further allows the fluid container 26 contained in the second compartment 24 to be chilled whilst the container 26 in the first compartment 22 is being used. Once the first compartment container 26 is empty, the container 26 can be replaced, the fluid dispensing system 10 inverted and milk can be drawn from the pre- chilled second compartment container. In this way a continuous supply of chilled milk is available.

The fluid container 26 comprises a blow moulded, LDPE storage bag 28 for storing the milk, a retaining tube 27 and a dispensing tap 30. The retaining tube 27 is hot plate welded to the bag 28 and then shrink wrapped around the dispensing tube 30. The bag 28 includes an outlet (not shown) which engages an inlet (see Figure 3) on the dispensing tap 30.

The fluid container 26 further comprises an HDPE support 32 which is used to carry product information.

The frame 20 is open at the top 34 and bottom 36 to allow a fluid container 26 to be inserted into the first compartment 22 or second compartment 24. The inner surface 33 of each compartment 22,24 is profiled to be complementary to the outer surface 29 of the flexible bag 28 so that as the fluid container 26 is inserted into the frame 20, the container 26 is guided to the correct position. A container 26 can be inserted into the frame be lowering the container 26 into the frame 20 or lowering the frame 20 over a container 26.

The first compartment 22 includes a front opening 38 for receiving the tap 30. The edges of the front opening 38 are configured to snap fit around the tap 30 once it is in the fully inserted position shown in Figure 2b. A similar front opening 39 is provided on the second compartment 24. The front openings 38,39 are arranged so that when there is a fluid container 26 in both compartments 22,24 the taps 30 are adjacent and lie in a horizontal plane through the frame midpoint.

The snap fit ensures the fluid container 26 in the lower compartment (in this case the second compartment 24), which is inverted with respect to the fluid container 26 in the upper compartment is secured in position and will not fall out.

The dispensing tap 30 is attached to the storage bag 28 such that when the tap engages the internal frame surface 33, the tap 30 slopes downwards from the back of the frame 20 to the front. This arrangement, shown in Figure 2b with the fluid container 26 secured in position, can be used by the user, particularly if the user has a visual impairment, to ensure his or her cup or bowl is correctly positioned below the tap 30 and to improve flow rates through the tap 30. The positioning of the taps 30 adjacent one another facilitates the assessment by the user of which tap 30 to use.

The frame 20 further includes lifting handles 37 and a gauge 40 to inform the user of the level of milk in the fluid dispensing system 10.

Referring now to Figure 3 there is shown a perspective exploded view of the fluid container of Figure 2a.

The support 32, the storage bag 28 and the tube 27 can clearly be seen. The remaining components make up the dispensing tap 30.

The tap 30 comprises a housing 50, a valve element and a venting means 70. The housing 50 comprises a front plate 52 defining a fluid outlet 54, a first body portion 55, a second body portion 56 defining a fluid inlet 58 and an end cap 59. In use, fluid, in this case milk passes into the housing 50 through the fluid inlet 58 and out of the housing 50 via the fluid outlet 54.

The volume of the metered dose supplied by the dispensing tap 30 is the volume of the housing 50 minus the volume of the valve element 60 minus the volume of the venting means 70. This volume can however be varied by using different sizes of end cap 59. A larger end cap 59 than the one shown in Figure 3 would extend further into the second body portion 56 and take up more of the internal volume of the second body portion 56, and hence reduce the overall volume of the tap 30.

The valve element 60 comprises an inlet sealing portion 62, a support portion 64, an outlet sealing portion 66 and a shaft 68. The inlet sealing portion 62, the support portion 64, and the outlet sealing portion 66 are all fixed to the shaft 68. The valve element components are designed to occupy as little space as possible within the housing 50 when the tap 30 is assembled.

The venting means 70 comprises a duckbill valve 72.

The end cap 59 includes an air inlet 74 to provide air to the duckbill valve 72.

The tap 30 further includes a lever 76, a torsion spring 78 and a tamper proof seal/lock 80. When assembled, the lever 76 is fixed to the end 69 of the shaft 68. The tamper proof seal hock sits in the fluid outlet 54 and engages the fluid outlet sealing portion 66 and the sides of the front plate 52 which define the fluid outlet 54, preventing relative movement between these components. When user wishes to dispense liquid for the first time, the seal/lock 80 can be pulled off.

The lock/seal 80 has a profiled surface, the profile being provided by the word "PULL" written in Braille.

Referring now to Figure 4a, there is shown an exploded side view showing hidden detail of the dispensing tap 30 of the fluid container 26 of Figure 2a.

The inlet aperture 58 can be seen more clearly in this Figure. Further clarity is provided as to the location of the torsion spring 78 which sits between the front plate 52 and the lever 76. The purpose of the torsion spring 78 is to bias the lever 76 to a zero flow position. As the lever 76 is actuated, a portion of the torsion spring 78 acts on the lever 76 in one direction and on a lug 82 extending from the front plate 52 in the opposite direction. As the lever 76 is moved, the torsion spring 78 is put under tension and the energy contained within the spring 78 acts to return the lever 76 to its rest, or zero flow, position.

Figures 4b and 4d show side views of the valve element 60 and housing 50 sub-assemblies respectively.

Figures 4c and 4e show end views of the sub-assemblies of Figures 4b and 4d.

In Figures 4c the valve element sub-assembly 60 is shown in a zero flow configuration. Superimposing this Figure on Figure 4e, it can be seen that the outlet sealing portion 66 is oriented to cover the outlet 54 defined by the front plate 52. Additionally, in this configuration, the inlet sealing portion 62 is not covering the housing inlet 58. Therefore fluid can flow from the storage bag (not shown) through the inlet 58 into the housing 50 but is then prevented from leaving the housing 50 by the outlet sealing portion 66.

If the valve element 60 is rotated anti-clockwise, the inlet sealing portion 62 moves to cover the inlet 58 and the outlet sealing portion 66 moves to open the outlet 54. In this configuration, the fluid contained within the housing 50 is allowed to vacate the housing through the outlet 54. As no further fluid can flow through the inlet 58 into the housing 50 a metered dose of fluid is delivered through the outlet 54. The size of the metered dose depends on the volume of the housing 50 less the volume of the parts of the valve element 60 and venting means 70 contained within the housing 50.

As can be seen from Figure 4e, there is an abutment 84 on an internal surface of the front plate 52. When a user rotates the valve element 60 to deliver a dose, the lower leading edge 86 of the valve outlet seal 66 engages the abutment 84 and further movement is prevented, thereby informing the user that dose position has been reached.

Still referring to Figures 4c and 4e, if the valve element 60 is rotated clockwise, a continuous flow orientation is achieved in which the inlet 58 and the outlet 54 are not covered by the inlet sealing portion 62 or the outlet sealing portion 66 respectively. In this configuration, fluid can flow from the storage bag through the inlet 58 into the housing 50 and out of the outlet 54 to deliver a continuous flow of fluid. A user knows he has reached the continuous flow position when the upper leading edge 88 of the outlet sealing portion engages the abutment 84.

Referring to Figure 4d and Figure 4e, the second body portion 56 defines a profiled external surface 90.

The profiled external surface 90 assists in correctly positioning the fluid container 26 within the frame 20 with the dispensing tap 30 sloping downwards and prevents the tap from rotating during actuation of the lever 76.

As the profiled surface 90 engages the edges of the frame opening 38 the tap 30 is guided into the correct position within the frame 22.

Once the fluid container 26 is in position, the edges of the frame opening 38 snap-fit around a first and second edge 92, 94 of the second body portion 56.

Figure 5a is a side view showing hidden detail of the dispensing tap 30 of the fluid container 26 of Figure 2a.

Figure 5b is an end view of the dispensing tap of Figure 2a showing the three positions of levee 76. The zero flow position is the middle of the three positions with the lever 76 shown in solid lines. To deliver a single metered dose, the lever 76 is rotated anti- clockwise to position "A". Once a dose has been delivered the user can let go of the lever 76 and it wiLl return to the zero flow position under the action of the torsion spring 78. To achieve continuous flow, the lever 76 is rotated clockwise to position "B", and again, once the desired amount of fluid has been delivered, the lever 76 can be released and it will return to zero flow position automatically.

Figures 6a and 6b are section views through section A-A of Figure 5a showing the outlet sealing portion 66 in a continuous flow configuration(Figure 6a) and in a metered flow configuration (Figure 6b) . As can be seen from Figure 6a, the upper leading edge 88 has engaged the abutment 84 to indicate to the user that the continuous flow position has been reached, and in Figure 6b, the lower leading edge 86 has engaged the other side of the abutment 84 to indicate to the user that the dose position has been reached.

Various modifications and improvements may be made to the embodiment described without departing from the scope of the invention.
