Abstract
A dispense nozzle 1 for a beverage dispenser comprises a cylindrical tube 3 provided with a slot 9 that extends longitudinally from a distal end 7 of the nozzle 1 for up to half the length of the nozzle 1 such that beverage drains automatically from the nozzle 1 on completion of dispense. The slot 9 has a width less than half the internal diameter of the nozzle 1 such that beverage does not spray from the slot during dispense. An end face of the nozzle 1 at the distal end extends at an angle of 20 degrees to a plane transverse to the longitudinal direction of the slot extends from the side of the end face closest to a proximal end thereof.
Description
BEVERAGE DISPENSE
This invention relates to dispense of beverages from a dispenser provided with a dispense nozzle. The invention has particular, but not exclusive application for dispense of alcoholic beverages such as beer, lager or cider.
When dispensing beer into a drinking vessel such as a glass, for example pint or half-pint measures, a full measure may not be dispensed into the glass if the dispense nozzle retains a volume of beer when the tap is closed. As a result, the volume of beer dispensed may vary slightly between dispenses. This is not a problem where the tap can be manually operated to "top-up" the glass to dispense the required measure.
However, such "topping-up" may not be possible for metered systems in which the tap is operated automatically leading to dispense of less than a full measure.
According to the present invention, there is provided a dispense nozzle for a beverage dispenser, wherein the nozzle is self-draining on completion of a dispense. By this invention, on completion of a dispense, any beverage in the nozzle is drained to ensure a full measure of beverage is dispensed.
An exemplary embodiment of the invention will now be described with reference to the drawings, wherein Figure 1 is a side view of a dispense nozzle embodying the invention; and Figure 2 is a longitudinal sectional view of the dispense nozzle shown in Figure 1.
The dispense nozzle 1 shown in the drawings comprises a cylindrical tube 3 of metal or plastics having a proximal end 5 for attaching the nozzle 1 to a dispense tap or valve (not shown) and a distal end 7 for dispense of beverage into a drinking vessel such as a glass (not shown). In this embodiment, the tube 3 has a length of 110mm, an outside diameter of 8 mm, and an internal diameter of 6.4 mm. These dimensions of the tube 3 are provided by way of example only and are not intended to be limiting on the scope of the invention.
The tube 3 is provided with a slot 9 extending longitudinally from the distal end 7 towards the proximal end 5. In this embodiment, the slot 9 has a length of 55 mm, i.e. half the length of the tube 3, and a width of 2.5 mm. These dimensions of the slot 9 are provided by way of example only and are not intended to be limiting on the scope of the invention.
We have discovered that the provision of the slot 9 allows beverage in the nozzle 1 at the end of each dispense to drain rapidly from the nozzle 1.
As a result, beverage is not retained in the nozzle 1 and a full measure of beverage is dispensed. In this way, the volume of beverage dispensed can be accurately controlled. This has particular advantages for a metered system with automatic operation of a dispense tap or valve to provide consistent dispense of the correct volume of beverage with each dispense.
We have also found that arranging the slot 9 in a longitudinal direction does not disrupt the flow of beverage and the beverage does not spray out of the slot 9. The lack of spray may be due to the slot 9 extending in the same direction as the liquid flow and being shorter than the overall length of the nozzle so that the column of liquid has already been formed in the upper part of the nozzle 1 and remains so along the length of the slot 9 in the lower part of nozzle 1.
We have further found that the time to drain the nozzle 1 at the end of dispense can be varied by altering the length and/or width of the slot 9.
In general, however, the slot 9 should be of shorter length than the nozzle 1 and of narrower width than the nozzle 1 so as not to disrupt beverage flow during dispense.
In addition to the slot 9, the tube 3 is provided at the distal end 7 with an angled face 11. In this embodiment, the end face 11 extends at an angle of 200 to a plane transverse to the length of the nozzle 1. The angle of the end face 11 is provided by way of example only and is not intended to be limiting on the scope of the invention.
We have found that the angled end face 11 of the nozzle 1 together with the end of the slot 9 helps to break the liquid meniscus at the end of the nozzle 1 and further assists draining of the nozzle 1.
The provision of the slot 9 and angled face 11 does not affect dispense and allows the rate of dispense to be varied without deterioration of pour quality. Moreover, the nozzle 1 can be immersed in the dispensed beverage within the drinking vessel so that the slot 9 is covered until the drinking vessel is lowered at the end of dispense whereupon the nozzle 1 can drain rapidly to ensure a full measure is dispensed into the drinking vessel.
It will be understood the invention is not limited to the embodiment above-described. For example, the nozzle I may be provided with a slot as described or any other suitable opening or series of openings that allow the nozzle 1 to be self-draining.
