Abstract
Description
- This invention relates to beverage dispense apparatus, in particular, but not exclusively for dispensing beer, lager, cider and like beverages. More especially, the invention relates to counter-top fittings for dispensing such beverages. For convenience, where the term "beer" is used hereinafter to describe the invention it will be understood that the invention applies equally to lager, cider and like beverages.
- Counter top fittings for dispensing beer typically employ a valve that can be operated manually or electrically to dispense the beer into a container placed under an outlet from the valve. Recently there has been a trend to dispense beer at low temperature and to provide counter-top fittings in which ice and/or condensation is formed on an outer surface of the fitting by circulating a coolant within the fitting. The coolant helps to prevent the beer warming up, especially between dispenses, and the formation of ice/condensation gives the impression to the customer that the beer is being dispensed at a low temperature.
- For some designs of counter-top fittings, the formation of ice/condensation can create a problem if water formed by the ice melting or from condensation formed on the fitting can drip into a container placed under the outlet from the valve and contaminate beer dispensed from the fitting into the container.
- Also, there is an increasing trend for retailers to provide greater choice to customers by introducing different beers - so called "guest beers" - on a regular basis. As a result, there is a need to adapt the counter-top fitting to change the branding when a different beer is to be dispensed.
- The present invention has been made for a consideration of the foregoing and seeks to provide an improved counter-top fitting for dispensing beverages such as beer, lager, cider in which ice/condensation can form on part of the fitting.
- According to a first aspect of the present invention, there is provided a counter-top fitting for dispensing a beverage comprising a first section provided with a dispense valve, a second section provided with a coolant chamber for circulating coolant such that ice/condensation can form on an outer surface of the second section, wherein a thermal break is provided to inhibit formation of ice/condensation on the first section.
- By this first aspect of the invention, formation of ice/condensation on the outer surface of the fitting is restricted to an area separated from the dispense valve such that water produced when the ice melts and/or from the condensation cannot contaminate beverage dispensed from the fitting.
- Preferably, the thermal break comprises a collar of low thermal conductivity material provided between the first section and the second section.
- Preferably, the first and second sections are releasably connected to each other by a lock nut that fits over the collar.
- Preferably, the second section is provided between the first section and a third section of the fitting providing a base for mounting the fitting on a support surface, wherein a thermal break is provided between the second section and the third section.
- Preferably, the thermal break comprises a sealing gasket of low thermal conductivity material provided between the second section and the third section.
- Preferably, the second section comprises an outer member, an inner member received within the outer member and sealed relative to the outer member at each end to define therewith the coolant chamber, wherein the outer member is removable and comprises a substantially cylindrical sleeve of high thermal conductivity material
- Preferably, an inlet and an outlet for circulating coolant through the chamber are provided at opposite ends of the chamber and wherein, in use, the outlet is arranged at an upper end of the chamber and the inlet is arranged at a lower end.
- Preferably, the inner member has one or more through bores for passage of one or more of a product line and a power supply line.
- According to a second aspect of the present invention, there is provided a method of producing ice/condensation on a counter-top fitting for dispensing a beverage comprising the steps of circulating coolant through a chamber in a first section of the fitting to form ice/condensation on an outer surface of the first section, and providing a thermal break between the first section and at least one further section of the fitting.
- By this second aspect of the invention, formation of ice/condensation is restricted to the outer surface of the first section.
- Preferably, the thermal break is provided between the first section and a second section having a dispense valve for dispensing beverage such that ice/condensation is restricted to an area of the fitting separate from the dispense valve.
- In this way, water produced when the ice melts and/or from the condensation cannot contaminate beverage dispensed from the fitting.
- According to a third aspect of the present invention, there is provided a font having a dispense valve for dispensing a beverage on a first part of the font, and a coolant chamber for circulating coolant to form ice/condensation on an outer surface of a second part of the font and a thermal break between the first and second parts.
- Preferably, the second part is provided between the first part and a third part of the font providing a base for mounting the font on a support surface with a thermal break between the second and third parts.
- According to a fourth aspect of the present invention, there is provided a method of controlling formation of ice/condensation on an outer surface of a beverage dispense font by providing the font with a thermal break.

- By this fifth aspect of the invention, ice/condensation forms on a removable part of the fitting whereby the fitting can be adapted for dispensing different beverages by removing the outer member and replacing it with another member appropriate to the beverage to be dispensed.
- Furthermore, by circulating coolant through a chamber between the outer member and the inner member, cooling of the outer member and hence formation of ice/condensation thereon is improved by direct contact between the coolant and the outer member.
- According to a sixth aspect of the present invention, there is provided a method of producing ice/condensation on a counter-top fitting for dispensing a beverage comprising the steps of circulating coolant through a chamber defined between an outer member and an inner member such that the coolant directly contacts the outer member to form ice/condensation on an outer surface of the outer member which itself forms an outer surface of the fitting, and passing a product line through the inner member so that the coolant does not directly contact the product line, wherein the outer member is removable.

collar 15 is made of plastic and has low thermal conductivity that provides a thermal break between the tube-in-tube assembly 4 and the L-shapedsleeve 12 that prevents ice/condensation forming on the outer surface of the L-shapedsleeve 12 which could run down into a glass or similar container placed under the dispensetap 13. - Likewise, the sealing gasket 3 is made of rubber and has a low thermal conductivity that provides a thermal break between the tube-in-tube assembly 4 and the
base 2 that inhibits ice/condensation forming on thebase 2 and also prevents water penetrating between thebase 2 and the tube-in-tube assembly 4. - In addition to the
badge 19, theouter sleeve 5 of the tube-in-tube assembly 4 may carry advertising or branding relating to the product being dispensed. If the product is changed, theouter sleeve 5 can be removed and replaced by adifferent sleeve 5 carrying advertising/branding appropriate to the product. - To replace the
outer sleeve 5, the circulation of coolant is stopped before disconnecting the L-shapedsleeve 12 by releasing thelocknut 17 and disconnecting the product line and power line, for example by employing self-sealing quick release connectors (not shown) that engage/disengage automatically when the L-shapedsleeve 12 is connected/disconnected. Theouter sleeve 5 can then be slid up and lifted off theinner component 6. - A new
outer sleeve 5 can then be fitted over and slid down onto theinner component 6. The L-shapedsleeve 12 can then be re-connected and thelocknut 17 tightened to effect a fluid-tight seal between theouter sleeve 5 andinner component 6 at the top and bottom of the tube-in-tube assembly 4 before re-starting circulation of coolant through the chamber 7. - As will be understood from the foregoing description of an exemplary embodiment, the present invention provides a counter-top fitting for dispensing a beverage in which ice/condensation forms on an outer surface of a part of the fitting that can be removed and replaced when changing the beverage to be dispensed and is separated from a part of the fitting on which the dispense tap is mounted by a thermal break that prevents ice/condensation forming on a part of the outer surface of the fitting where it could drip into a glass placed under the dispense tap.
- Although the invention has been described with particular reference to a counter-top fitting for dispensing beverages in the form of a swan neck font, it will be understood that the invention is not limited to such fittings and that any of the features described herein could be employed in other dispense equipment and fittings where it is desired to provide a coolant chamber and/or to restrict the area over which ice/condensation may form.
- It will also be understood that the invention is not limited to fittings for the dispense of alcoholic beverages such as beer, lager cider and the like and features of the invention may also be employed in fittings for the dispense of non-alcoholic beverages.
- Furthermore, it will be appreciated that the invention is not limited to the embodiment above-described and that various changes may be made. For example, the outer sleeve may be of cylindrical shape as described or any other shape that allows the outer sleeve to be detached from the inner component to change the outer sleeve.
- The outer sleeve may incorporate one or more windows that may be illuminated to produce different visual effects for the customer. Where provided a window may be in the form of a logo or brand name.
- Other modifications will be apparent to those skilled in the art. The fitting may be provided with more than one dispense tap for dispensing the same or different product. Other changes that can be made will be apparent to those skilled in the art.
