Appeal 2007-2488
Application 10/081,483
1 to enable the beverage to be dispensed from the container and in which
2 the beverage is a liquid having a sparingly soluble effervescence inducing
3 gas dissolved therein, the beverage product being characterized in that the
4 beverage is held under a gaseous pressure in the head space above the
5 liquid beverage in the container that is sufficient to cause the beverage to
6 be discharged directly into the mouth of a consumer from the dispenser
7 as an effervescent fluid when the valve is open
8
9 wherein the beverage is held under a gaseous pressure in the
10 headspace of at least 2.5 atmospheres gauge at 5 to 15º and the valve is
11 one which is designed to be opened via the consumer’s mouth.
12
13 2. According to the Specification, the sparingly soluble effervescence
14 inducing gas “can be oxygen, nitrogen, nitrous oxide, hydrogen, a
15 noble gas, a gaseous hydrocarbon or a mixture thereof.”
16 (Specification at 9).
17 3. The effervescent beverage results from “placing a liquid beverage in a
18 container, sealing the container, introducing a sparingly soluble
19 effervescence inducing gas into the container so that the gaseous
20 pressure in the headspace of the container is sufficient to cause the
21 beverage to be discharged from the dispenser as an effervescent fluid
22 when the valve is open….” (Specification at 5-6).
23 4. The dispensed beverage, which is “preferably tea or coffee based, or
24 water or a flavoured water”, is said to “contain very small bubbles of
25 the sparingly soluble gas and does not give the prickly sensation
26 produced by effervescence of a more soluble gas such as carbon
27 dioxide” and is described as “provid[ing] the consumer with a smooth
28 and silky sensation, which can enhance flavour delivery from a
29 flavoured beverage.” (Specification at 4).
