Definitions
- the present invention relates to a device for preparing a carbonated beverage.
- One of these devices comprises a stand in which a carbon dioxide cartridge is accommodated.
- This cartridge contains about 500g of carbonic acid and is connected to an outlet via a manually operated metering device.
- Special bottles with different capacities are supplied with this previously known device, which are filled with tap water, for example, and which can then be quickly connected to the outlet of the stand using a bayonet catch.
- Each operation of a push button causes the metering device to emit a predetermined amount of carbon dioxide, which is mixed with the water.
- the object of the present invention is to provide a device which does not have the disadvantages mentioned and other disadvantages.
- FIG. 1 shows in a vertical longitudinal section a first embodiment of the present device
- Fig. 2 partially in a vertical longitudinal section a second embodiment of the present device and Fig. 3 partially in a vertical longitudinal section a third embodiment of the present device.
- the device according to FIG. 1 for the preparation of a beverage containing carbon dioxide has a housing 1 for accommodating a carbon dioxide cartridge 2.
- the housing 1 of this device can be screwed onto a beverage bottle 3, of which only the neck 4 of the same is shown in the drawing.
- This bottle 3 can be a commercially available plastic bottle, e.g. be made of PET, which has a volume of one and a half liters.
- Beverages containing carbon dioxide, such as mineral water, Coca-Cola, etc. are already sold in such bottles. After you have emptied such a purchased bottle, you can use the device at hand to prepare a carbonated drink yourself.
- the present device can also be used on special bottles which are one of the components of the device described in the introduction and belonging to the prior art.
- the housing 1 of the device comprises a first or lower half 10 and a second or upper half 40.
- the lower housing half 10 can be screwed onto the bottle 3 or the bottle neck 4.
- These housing housings 10 and 40 are bowl-shaped or essentially cylindrical, and they have cavities or cavities 11 and 12, respectively.
- the inner wall of the respective cavity 11 or 12 in the housing halves 10 and 40 is essentially zy li nderiformi g and it has an axis of rotation A.
- the housing halves 10 and 40 are assigned to one another in such a way that the axes A of these halves 10 and 40 are aligned with one another.
- the side walls of the housing halves 10 and 40 are also designed such that inside the housing 1 the carbon dioxide cartridge 2 can be arranged.
- the carbonic acid cartridge 2 has a container 5 for the carbonic acid.
- This container comprises a cylindrical jacket 33.
- a gas-tight bottom 35 At one end of this jacket 33 there is a gas-tight bottom 35, which is advantageously convex.
- a front end wall 34 of this cartridge 2 closes gas-tight, which is also essentially convex.
- an essentially cylindrical neck 6 of the cartridge 2 In the middle of this front wall 34 there is an essentially cylindrical neck 6 of the cartridge 2, which protrudes from the outside of this front wall 34 and whose longitudinal axis coincides with the axis A of the cylindrical liner-shaped jacket 33 or the device.
- the end walls 34 and 35 of the cartridge 2 shown in FIG. 1 have the shape of a spherical cap.
- the diameter of the cylindrical cartridge shell 33 is many times smaller than the diameter of that ball, of which the end bottoms 34 and 35 represent a spherical cap.
- the end bottoms 34 and 35 of the cartridge 2 shown in FIG. 1 are relatively flat or slightly curved.
- the inner walls 13 and 14 of the cavities 11 and 12 in the housing halves 10 and 11 are cylindrical in shape.
- the shape of the bottom wall 15 or 16 of the respective cavity 11 or 12 corresponds to the shape of the associated end wall 34 or 35 of the carbon dioxide cartridge 2, which rests on the respective bottom wall 15 or 16 of the housing 1.
- the bottom wall 15 or 16 essentially has the shape of a spherical cap.
- the bottom wall 15 or 16 is only flat or that it has the shape of a truncated cone.
- a recess 17 is made, the inner wall 18 of which is practically cylindrical.
- the axis of this recess 17 coincides with the axis A of the device.
- the diameter of the recess 17 is dimensioned such that the neck 6 of the carbon dioxide cartridge 2 can be inserted in a sealed manner in this recess 17.
- the diameter of the inner wall 18 of this recess 17 can be larger than the outer diameter of the cartridge neck 6. Then, however, it is necessary that a seal in the area of the transition between the lower floor 15 and the side wall 18 of the recess 17 19 is arranged.
- This seal 19 can be designed as a ring made of a resilient material, which rests and is attached in a gas-tight manner on the edge part of the cavity floor 15 which adjoins the beginning of the recess 17.
- the seal 19 is only hinted at because the illustration in the drawing shows that embodiment of this device in which the neck 6 of the cartridge 2 sits gas-tight in the recess 17.
- the seal 19 must seal or fill in the entire distance between the lower cavity floor 15 and the lower end floor 34 of the cartridge 2.
- That edge part of the round body of the respective housing half 10 or 40, which surrounds the mouth of the cavity 11 or 12 in the housing halves 10 or 40, is provided with a half 7 or 8 of a thread.
- the thread 7 of the lower housing half 10 is worked into a vertically running bottom of a circumferential shoulder, which is executed from the outside of this housing half 10 in this edge part thereof.
- the thread 8 of the upper housing half 40 is machined into a vertically extending bottom of a circumferential shoulder, which is executed from the inside of this housing half 40 in the edge part of this second housing half 40.
- These thread halves 7 and 8 are such that the housing parts 10 and 40 can be screwed together. It is advantageous if these threads 7 and 8 have a pitch that is as small as possible because this makes it easier to control the filling of the beverage bottle 3 with carbon dioxide.

- the cross section of the cavities 11 and 21 in the lower half 10 of the housing is essentially circular.
- a channel 26 which connects the two cavities 11 and 21 in the lower housing half 10 in terms of flow g.
- a pipe section 27 is inserted gas-tight, the length of which is greater than the thickness of the Intermediate wall 25. Consequently, this pipe section 27 passes through the intermediate wall 25 and the end parts 28 and 29 of this pipe section 27 protrude from the two sides of the intermediate wall 25.
- the first pipe section end 28, which projects into the interior of the first housing half 10, is intended and designed for actuating a closure device on the carbon dioxide cartridge 2.

- the second pipe end 29, which projects into the receiving space 21 for the bottle neck 4, is designed as a valve.
- the mouth of this second pipe end 29 lying in the axis of the pipe section 27 is closed by a transverse wall 44. Openings 31 are made in the wall of this pipe section end 29 and are covered by a sleeve 32 made of a rubber material.
- This sleeve 32 surrounds at least that section of this raw piece end 29 in which the wall openings 31 are made.
- the sleeve 32 allows that carbonic acid can only flow back into the beverage bottle 3 but not back. In addition, this sleeve 32 dampens the flow of carbon dioxide into the beverage bottle 3.
- the second housing half 40 has a base body 41.
- the outside of this base body 41 is provided with means 45 which enable this second housing half 40 to be screwed onto the first housing half 10 in an easily executable manner.

While the upper housing half 40 is screwed onto the lower housing half 10, this gap initially disappears. Then the cartridge neck 6 and / or the front wall 34 of the cartridge 2 lying below lies on the seal 19 in the lower housing half 10, whereby the recess 17 in the lower housing half 10 is sealed against backflow of the gas into the interior of the device.
- a dent 39 is made in the central region of the bottom wall 16 of the cavity 12 in the second housing half 40, which serves to accommodate the bottom part of such a carbonic acid cartridge.
