Definitions

  • the present invention relates to a modular beverage dispensing assembly.
  • the present invention relates to a modular beer dispensing assembly, to which the following description refers purely by way of example.
  • a modular beverage dispensing assembly according according to the preamble of claim 1 is known from WO 2004099060 .
  • PCT Patent Application WO2007019848 discloses an easy-carry cooled-beer dispensing assembly substantially comprising an undeformable, substantially cylindrical outer pressure container made of plastic and fitted with a removable airtight bottom cap for access to the inside; an electric reciprocating compressor for maintaining the air inside the pressure container at higher than atmospheric pressure; and a removable cartridge inserted inside the pressure container and in turn comprising a substantially bottle-shaped collapsible container designed to fit inside the pressure container, with its neck facing the removable bottom cap of the pressure container, and which is originally filled completely with beer or other beverage.
  • the pressure container bottom cap is fitted with a central cylindrical sleeve, which projects towards the centre of the pressure container, coaxially with the longitudinal axis of the pressure container, and communicates with the outside through a central hole formed through the wall of the bottom cap; and the neck of the collapsible container is designed to fit inside the cylindrical sleeve, so the base of the neck rests on the distal end of the sleeve, compressing annular seals on the sleeve.
  • the annular seals are designed to prevent compressed-air leakage from the pressure container when the neck of the collapsible container is inserted fully inside the cylindrical sleeve of the bottom cap.
  • the removable inner cartridge also comprises a sealing cap for airtight sealing the opening in the neck of the collapsible container; and an outflow hose connected at one end to the sealing cap of the cartridge, and extending outwards of the pressure container through the cylindrical sleeve in the pressure container bottom cap.
  • the easy-carry beer dispensing assembly comprises a refrigeration compartment designed to house the outer pressure container vertically and in rocking manner; and a manually operated metering valve fitted externally to the top of the refrigeration compartment, and connected by the outflow hose to the collapsible container of the removable cartridge.
  • the compressor pressurizes the air inside the pressure container, the difference in pressure deforms the collapsible container, so the liquid inside (beer or other beverage) is forced to flow under pressure along the outflow hose to the metering valve, from which it is tapped by the user.
  • the Applicant has realized that the above-described easy-carry beer dispensing assembly, though ensuring a much higher standard of hygiene than conventional beer tap systems (the removable cartridge is disposable), is not suitable for systems requiring a higher operating pressure, for example those systems where the pressure containers are remote from the place where the beverage is actually dispensed (and possibly cooled).
  • the Applicant has realized that if the overpressure inside the pressure container described in W02007019848 , which is a cylindrical plastic container with conventional smooth walls, is increased to values required to deliver the beverage to a remote dispenser, this overpressure could not be tolerated by the container, with risks of mechanical breakage.
  • a pressure container made of plastic or other economical material, that has an opening/closure system that is easy-to-handle and able to withstand relatively high pressures.
  • a modular beverage dispensing assembly as claimed in Claim 1 and preferably, though not necessarily, in any one of the Claims depending directly or indirectly on Claim 1.
  • the Applicant has found a very efficient, safe and easy-to-handle opening/closure system for a pressure container, wherein the pressure container is formed by two hollow bodies which can be advantageously made of plastic, and are hermetically joined to one another by an outer coupling belt or ring nut which fastens one another the lateral walls of the hollow bodies and, at the same time, encircles and tightens these lateral walls next to the joint between the hollow bodies, so to improve the high-pressure resistance of the pressure container.
  • the joint area between the two hollow bodies in fact, is the part of the pressure container subjected to the greatest mechanical stress, and the outer coupling belt or ring nut allows an even distribution of the mechanical stress all around the perimeter of pressure container.
