Abstract
Abstract A machine for the production of aerated beverages, employing the method of dissolving a flavoring (and/or sweetening) substance sealed in a cartridge with an aqueous liquid in which the aerated liquid medium, usually carbonated water, is first fed to a vessel underlying the cartridge, after which the cartridge is pierced and the substances contained therein fall into the vessel which already holds the aerated or carbonated liquid medium. The machine can also be used in the conventional manner for the preparation of ''''flat'''' beverages by cutting off the aerated liquid-medium feed.

Claim 1
Independent Claim
18 words
The machine according to claim 1, in which the fluid introduced into the cartridge is a pressurized gas.
Claim 2
Dependent Claim
13 words
The machine according to claim 2, in which said gas is carbon dioxide.
Claim 3
Dependent Claim
23 words
The machine according to claim 1, in which the fluid introduced into the cartridge is water under pressure existing in a water main.
Claim 4
Dependent Claim
17 words
The machine according to claim 1, in which the fluid introduced into the cartridge is compressed air.
Claim 5
Dependent Claim
19 words
The machine according to claim 1, in which the fluid introduced into the cartridge is air under atmospheric pressure.
Claim 6
Dependent Claim
40 words
The machine according to claim 1 in which said operable means includes a tool mounted for movement toward and away from the supported cartridge, and a hollow needle carried by the tool for perforating the upper end of the cartridge.
Claim 7
Dependent Claim
47 words
The machine according to claim 7, in which said tool has a through-bore which communicates with outlet perforations of the hollow needle and with a duct for the fluid which forces the flavoring substance from the cartridge, respectively, and valve means to open and close the duct.
Claim 8
Dependent Claim
35 words
The machine according to claim 8, in which the lower end of the cartridge is kept closed by a force which is less than the opening force imparted by the fluid introduced into the cartridge.
Claim 9
Dependent Claim
28 words
The machine according to claim 8, in which the lower end of the cartridge is provided with a removable extension for opening the cartridge at its bottom portion.
Claim 10
Dependent Claim
43 words
The machine according to claim 10, in which the dimensions of the outer perimeter of the cartridge and the inner perimeter of the supporting member are such as to cause the cartridge to adhere closely to the inner perimeter of the supporting member.
Claim 11
Dependent Claim
19 words
The machine according to claim 11, in which the lower end of the cartridge projects beyond the supporting member.
Claim 12
Dependent Claim
150 words
The machine according to claim 8 including a valve for opening and closing the feeding means for the carbonated water, first control means operatiVe for opening the valve for the carbonated water feeding means to permit water to flow into the collecting vessel and for closing said valve when the desired amount of water has entered the vessel, second control means operative after closing of said valve for the carbonated water feeding means to move the tool toward the cartridge so that the needle perforated the upper end of the cartridge, third control means operative to open the valve means for the duct for the fluid for introducing the fluid into the cartridge via the through-bore and outlet perforations, and further control means operative to close the valve means for the fluid duct and move the tool away from the cartridge to allow removal of the cartridge from the support.
Claim 13
Dependent Claim
30 words
The machine according to claim 13, in which additional ducts for introducing into the interior of the cartridge a number of different liquids communicate with said through-bore of the tool.
Claim 14
Dependent Claim
27 words
The machine according to claim 14, in which each of said additional ducts is provided with an independently operable valve for opening and closing said additional duct.
Claim 15
Dependent Claim
17 words
The machine according to claim 15 in which one of said additional ducts introduces cold, nonaerated water.
Claim 16
Dependent Claim
16 words
The machine according to claim 15 in which another of said additional ducts introduces hot water.
