[0026] Detailed description

[0027] Further embodiments of the device of the present invention are described herein and with reference to figures 1 -4.

[0028] As illustrated in figure 1 the present invention in one embodiment concerns a device (10) for holding a bottle (14) for carbonated beverage. The device is shown as a cross section. The device could be configured to fit into a carbonator as known in the prior art or into a new carbonator with a more customer compliant design. The bottle (14) has wall (12) defining the bottle (14) and a top part (30) having an opening adapted to receive the beverage, and the top 10319PC00

[0029] 5 part (30) of the bottle has a flange (16) adjacent the opening, which flange (16) is adapted to engage with at least two holding parts (20, 22, 24). The top part (30) of the bottle has a threaded part (18) adjacent the opening, which threaded part (18) is adapted to engage with a lid having a corresponding threaded part to close the bottle and avoid wasting the beverage. The two illustrations A and B are the same bottle and device of the present invention showing the unlocked position of the holding part (20, 22, 24) and the locked position of the holding part (20, 22, 24), respectively. Each of the holding parts (20, 22, 24) has a top part (22) a midsection (20) and a clow-like section (24) which clow-like section is designed to engage with the flange (16) to prevent the bottle from sliding out of the device during use of the carbonator. The holding parts are designed to move radially from a first position (A) to a second position (B) and vice versa. In the present embodiment the holding parts (20, 22, 24) defines an annular array of L-shaped or claw-like elements (20, 24) located with respect to each other at their root ends (22) and each such element being resiliently flexible in the radial sense about its root end (22). The first position (A) defines an opening for receiving the top part (30) of the bottle (14) and the flange (16) and the second position (B) illustrates when clow-like part (24) of the holding element (20, 22, 24) engages with the flange (16) to hold the bottle (14) in a position ready to start carbonation which position prevent withdrawal of the bottle. Further illustrated are a separate locking element (28) engaging with the at least two holding parts (20, 22, 24). The locking element (28) is movable from a first unlocked position (A) to a second locked position (B) in an axial direction and vice versa. When the locking element (28) is in the first unlocked position (A) it may be in a position where the locking element (28) does not touch the holding elements (20, 22, 24) and allows the holding parts (20, 22, 24) to be in a resting stage pending flexing to the locked position (B) or where the locking element (28) touches the holding elements (20, 22, 24) and allows the holding parts (20, 22, 24) to be in a flexing stage and open for receiving the bottle and pending further flexing to the locked position (B). Further illustrated is a separate steering element (26) in physical contact with the locking element (28) in both the unlocked position (A) and the locked position (B) and during movement of the steering element (26). Thus, the steering element (26) is configured to guide the locking element (28) to move the locking element (28) from the first unlocked position (A) to the second locked position (B) 10319PC00

[0030] 6 and vice versa and wherein the separate steering element (26) is configured to rotate (without moving up or down relative to the locking element (28)) to allow moving the locking element (28) between the first unlocked position (A) and the second locked position (B) wherein said movement of the locking element (28) is in the axial direction.

[0031] Figure 2 illustrates the present invention as shown in figure 1 concerning a device (10) for holding a bottle (14) for carbonated beverage. The embodiment (20, 22, 24, 26, 28) is shown incorporated in a carbonator (40) said carbonator (40) having a top part (44) containing the device (10 in figure 1 consisting of features shown as 20, 22, 24, 26, 28) and shown in a locked position of the device wherein further details of the carbonator top part is shown, such as a nozzle (42) for carbonation of a liquid, such as water, and elements for operation of said carbonater (without specific references).

[0032] Figure 3A, 3B and 3C illustrates an embodiment of the present invention as indicated in figures 1 and 2, in greater details. The three key elements of the present invention are shown separate as (50), (70) and (100). The first element is the holding part element (50) comprising multiple holding parts (58a-58e, 60a-60e, 62a-62e) each shown having a root end (59a-59e) fixed to an annular ring (52), said ring (52) comprising an opening (54) allowing space for a hose to pass and four cavities (56a-56d) which consist of screw holes that are made to secure the holding element in the carbonation machine. Each holding part (58a-58e) is resiliently flexible in the radial sense about its root end (59a-59e) and further comprises an annular array of L- shaped or claw-like elements (60a-60e, 62a-62e) at the opposite end of the root end (59a-59e). Each L-shaped or claw-like elements (60a-60e, 62a-62e) has an opening or a recession (64a- 64e) creating a double claw-like element for gripping and holding the flange (16 in figure 1 and 2) of the bottle (12, 14 of figure 1 and 2). The opening or recession (64a-64e) is a feature that further strengthen the positioning of the holding parts configured to engage with a corresponding protrusion (88, 90, 92) shown in figure 3B and located at the inner surface (73) of the separate locking element (70) shown in figure 3B.

[0033] The second element is the locking element part (70) comprising an annular ring (72) having a cylindrical inner surface (73) and a cylindrical outer surface (71). Protrusions (88, 90, 92) are shown in the cylindrical inner surface (73) which protrusions are adapted to engage 10319PC00

[0034] 7 with the opening or recession (64a-64e) shown in figure 3A. Further the annular ring (72) comprises various protrusions (74, 76, 78, 80, 82, 84, 86) on the outer surface (71) which protrusions engage with guiding means of the third element being the steering element (100).

[0035] The third element is the steering element (100) comprising an annular ring (102) having a cylindrical inner surface (103) and a cylindrical outer surface (101). The annular ring (102) has protrusions (110, 112, 114, 116) on the cylindrical outer surface (101), which protrusions (110, 112, 114, 116) stabilize the annular ring (102) when in operation ensures that the mechanism (10) does not fall out of the carbonation machine while still allowing the steering element to rotate. In addition, the annular ring (102) has protrusions (104, 106, 108) pointing downwards at the edge of the annular ring (102) when in operation, which protrusions (104, 106, 108) fits into an outer ring (not shown) that is equipped with a handle (not shown), allowing the user to rotate the steering element (100) by using the handle. On the inner surface (103) the annular ring (102) has guiding tracks (122, 126) in the inner surface wall (120, 124) configured for guiding the protruding element (74, 76, 78, 80) adjacent the upper part of the annular ring (72) (figure 3B) when in operation. Further guiding tracks (128, 130) in the inner surface wall (120, 124) are configured for guiding the protruding element (82, 84, 86) adjacent the lower part of the annular ring (72) (figure 3B) when in operation.

[0036] Figure 4 illustrates an embodiment of the present invention as indicated in figure 3A-C. The three key elements are shown separate as (50), (70) and (100) now engaging with each other, such as explained above under description of figure 1, 2 and 3. When turning the steering element (100) either clockwise or counterclockwise it causes the holding element (70) to move up and down to move the holding parts of the holding element (50) in the radial direction to unlock and lock the bottle into the carbonator top part. As indicated in figure 4 the locking element (70) is fully constrained by the steering element (100) and the L-shaped or claw-like elements (shown as 60a-60e, 62a-62e in figure 3 A) of the holding element (50) are constrained by the locking element (70).

[0037] The particular embodiments as described in figures 1-4 have been optimized through extensive development work to produce a device that is made from polymeric material such as 10319PC00
