[0078] Furthermore, the terms first, second, third and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a sequential or chronological order. The terms are interchangeable under appropriate circumstances and the embodiments of the disclosure can operate in other sequences than described or illustrated herein.

[0079] Moreover, the terms top, bottom, over, under and the like in the description and the claims are used for descriptive purposes and not necessarily for describing relative positions. The terms so used are interchangeable under appropriate circumstances and the embodiments of the disclosure described herein can operate in other orientations than described or illustrated herein.

[0080] The term “comprising”, used in the claims, should not be interpreted as being restricted to the means listed thereafter; it does not exclude other elements or steps. It needs to be interpreted as specifying the presence of the stated features, integers, steps or components as referred to, but does not preclude the presence or addition of one or more other features, integers, steps or components, or groups thereof. Thus, the scope of the expression “a device comprising means A and B” should not be limited to devices consisting only of components A and B. It means that with respect to the present disclosure, the only relevant components of the device are A and B.

[0081] FIGS. 1A and 1B show a device 100 according to an embodiment of the present disclosure for preparing a frozen food product, such as for example ice cream or sorbet, from a liquid mixture. Further details of the device 100 are shown in the FIGS. 2A, 2B, 3A, 3B and 4. The device 100 comprises a first sub-unit 101 which is arranged for preparing a frozen food product in a first cup 200, and a second sub-unit 102 which is arranged for preparing a frozen food product in a second cup 200, different from the first cup 200. The first sub-unit 101 and the second sub-unit 102 are arranged in a similar manner and operate independent from each other, such that two cups 200 of frozen food product can be prepared separate from each other. In alternative embodiments, the device 100 may comprise only a single sub-unit 101, 102, or may be provided with more than two of the sub-units 101, 102. Since the first sub-unit 101 and the second sub-unit 102 are arranged in similar manner, the features of the device 100 will be discussed below only with respect to one of the sub-units 101, 102.

[0082] FIGS. 5A-5C and 6A show a cup 200 according to an embodiment of the present disclosure for use with the device 100. Other embodiments of the cup 200 according to the present disclosure are shown in the FIGS. 7A and 8A. The cup 200 comprises a cup wall 210 which encloses a holding volume 201. The holding volume 201 is arranged for holding the liquid mixture therein, and also for holding the frozen food product therein after the frozen food product has been prepared form the liquid mixture. At the top, the cup 200 comprises a top opening 202 via which the holding volume 201 can be accessed. The cup 200 may be pre-filled with the liquid mixture, whereby the top opening 202 is sealed off by one or more sealing elements (not shown), such as a sealing membrane and a lid. The sealing elements can then be taken off the cup 200 before the cup 200 is to be used with the device 100. The cup 200 may also be a reusable cup 200, which is filled with a liquid mixture from a package pre-filled with liquid mixture or with a self-made liquid mixture right before the cup 200 is to be used with the device 100.

[0083] The device 100 comprises, as can be seen in FIGS. 1A and 1B and shown in more detail in FIGS. 2A and 2B, at its bottom a cup holder 300 which is arranged for holding the cup 200, preferably in a fixed position, while the frozen food product is being prepared in the cup 200. Therefore, the device 100 comprises a cavity 310 in which the cup 200 can be received via an entrance opening 304.

[0084] As can be seen for example in FIG. 2A, the entrance opening 304 of the cavity 310 is located in a first upper surface 301 of the cup holder 300. This first upper surface 301 is formed by a bottom surface 301 in a recessed area 306 in a second upper surface 305 of the cup holder 300. In this arrangement the second upper surface 305 is thus located above the first upper surface 301 in a height direction H. In alternative embodiments, such as for example shown in FIGS. 7A and 7B, the cup holder 300 can also be provided with a single flat first upper surface 301. The first upper surface 301 being located in the recessed area 306 is however advantageous for containing liquid mixture or frozen food product which is spilled accidentally out of the cup 200 in the recessed area 306, such that it is prevented from further spreading over the device 100.

[0085] The device 100 also comprises a cooling unit 400, as can be seen in FIGS. 1A and 1B and shown in more detail in FIGS. 2A and 2B. The cooling unit 400n is arranged for cooling the cavity 310 of the cup holder 300, and more specifically for cooling a cup 200 received in the cavity 310. The cooling unit 400 should be arranged to provide sufficient cooling for freezing liquid mixture contained in the cup 200 while preparing a frozen food product from the liquid mixture. The cooling unit 400 may comprise one or more cooling pipes, which are arranged around the cavity 310, and through which a cooling fluid is transported for cooling the cavity 310. The cooling unit 400 may however also be arranged in any other way know to the person skilled in the art for cooling the cavity 310 of a device 100 for preparing a frozen food product from a liquid mixture.

[0086] The device 100 also comprises a stirring unit 500 which is arranged above the cup holder 300, as can be seen in FIGS. 1A and 1B. The stirring unit 500 comprises a stirring element 550, which is shown in detail in FIG. 4. The stirring unit 500 is configured for stirring the liquid mixture in the cup 200 by said stirring element 550 for preparing the frozen food product. The stirring element 550 is removably connectable to the stirring unit 500, such that the stirring element 550 can be taken out of the device 100 for cleaning.

[0087] The stirring unit 500 comprises a moveable portion 501 which is moveable along a height direction H between a first position and a second position. In the first position, as shown for first sub-unit 101 of the device 100 in FIGS. 1A and 1B, the stirring element 550 is arranged outside of the cup 200, such that it is easily accessible for disconnecting it from the stirring unit 500 for cleaning and for connecting it to the stirring unit 500. In the second position, as shown for the second sub-unit 102 of the device 100 in FIGS. 1A and 1B, the stirring element 550 is arranged inside the cup 200 such that the stirring unit 500 can stir the liquid mixture in the cup 200 by the stirring element 550 for preparing the frozen food product.

[0088] The stirring unit 500 is also provided with a protection screen 510, which is shown for both sub-units 101, 102 of the device 100 in FIG. 1A and for the second sub-unit in FIG. 1B. In FIG. 1B, the protection screen 510 has however been omitted for the first sub-unit 101 of the device 100, but only to show the features of the device 100 located behind the protection screen 510. The protection screen 510 extends downwards from the moveable portion 501 of the stirring unit 500, and moves together with the moveable portion 501 of the stirring unit 500. When the moveable portion 501 of the stirring unit 500 is in the second position, the protection screen 510 closes off an area located above the cup 200 and between the cup holder 300 and the moveable portion 501 of the stirring unit 500. This prevents access to the moving stirring element 550 when the frozen food product is being prepared, which is beneficial for safety. A further safety feature is that, in the second position of the moveable portion 501 of the stirring unit 500, the bottom edge 511 of the protection screen 510 supports on the first upper surface 301 near an edge 307 of the recessed area 306, such that it is difficult to get underneath the protection screen 510 and lift it up to gain access to the closed off area. The protection screen 510 is also beneficial for the cleanliness of the device 100, since it contains spilled liquid mixture or frozen food product in the closed off area, and prevents it from further spreading over the device 100.

[0089] The stirring unit 500 also comprises a drive system 520 for driving the stirring motion of the stirring element 550 in the cup 200, which drive system 520 is shown in detail in the FIGS. 3A and 3B. The drive system 520 comprises a motor (not shown) which is coupled to a first rotation shaft 522 for rotating the first rotation shaft 522. The first rotation shaft 522 is arranged in the height direction H along a first axis A1, which goes centrally through the cup 200 when received in the cavity 310 of the cup holder 300. The first rotation shaft 522 is connected to a secondary rotation shaft 523 by a planetary gear mechanism 524. The secondary rotation shaft 523 is arranged in the height direction H along a second axis A2, which goes centrally through the stirring element 550. The second axis A2 is located at a predetermined offset o from the first axis A1. The stirring element 550 is connected to the second rotation shaft 523 by a coupling mechanism 530. In this configuration, the motor rotating the first rotation shaft 522 causes the rotation of the stirring element 550 together with the second axis A2 around the first axis A1 and simultaneously the rotation of the stirring element 550 around the second axis A2. In alternative embodiments, other configurations of the drive mechanism may be used for rotating the stirring element 550, such as for example a drive mechanism with a single rotation shaft for rotating the stirring element 550 around a single axis.

[0090] The coupling mechanism 530 for connecting the stirring element 550 to the second rotation shaft 523 is provided with a spring 539 or other biasing element which is arranged for pushing the stirring element 550 downwards. This spring 539 causes the stirring element 550 to be pushed firmly against the cup 200 when the moveable portion 501 of the stirring unit 500 is in the second position, such that there is a good contact between the stirring element 550 and the cup 200 for scraping frozen liquid mixture from the cup wall 210 when frozen food product is being prepared from the liquid mixture in the cup 200.

[0091] The cup 200, as shown in the FIGS. 5A-5C. 6A, 7A and 7B, is provided such that it can easily be taken out of the cup holder 300 of the device 100. Therefore, the cup 200 comprises at its top a circumferential flange 220 surrounding the top opening 202. The circumferential flange 220 extends outwards and sideways from the cup 200, i.e. away from the cup 200 in radial or transverse directions T perpendicular to the height direction H. Furthermore, the cup 200 has a height h such that the cup 200 extends a distance d above the first upper surface 301 of the cup holder 300 when the cup 200 is received in the cavity 310 of the cup holder 300. For this purpose, the cavity 310 of the cup holder 300 has a height equal to the height h of the cup 200 minus the distance d that the cup 200 extends above the first upper surface of the cup holder 300. In the embodiments shown, the distance d is approximately 5 mm. In alternative embodiments, the distance d can however also be larger or smaller. In some embodiments, the distance d is in the range from 2-15 mm. With the cup 200 extending the distance d above the first upper surface 301 of the cup holder 300, the circumferential flange 220 at the top of the cup 200 is thus located at the distance d above the first upper surface 301 of the cup holder 300. In this way the circumferential flange 220 of the cup 200 is easily accessible for grabbing it from the sides for taking it out of the cavity 310 of the cup holder 300.

[0092] In the embodiments shown, the circumferential flange 220 is provided along at least a part of its circumference with a second extension 224 which extends downwards from the circumferential flange 220 up to the first upper surface 301 of the cup holder 300 when the cup 200 is received in the cavity 310 of the cup holder 300. The second extension 224 extends thus downwards from the circumferential flange 220 over the distance d that the cup 200 extends above the first upper surface 301. In alternative embodiments, the distance over which the second extension 224 extends downwards can however also be smaller. The downwards second extension 224 is beneficial since it offers a larger surface to grab onto for easily taking the cup 200 out of the cavity 310 of the cup holder 300.

[0093] The cup 200 and the cup holder 300 of the device 100 are also provided for preventing the cup 200 from rotating in the cavity 310 of the cup holder 300 when the stirring unit 500 is stirring the stirring element 550 in the cup 200 for preparing the frozen food product from the liquid mixture.

[0094] For the embodiment of the cup 200 shown in FIGS. 5A and 6A, the cup holder 300, such as shown in FIG. 2A and also in FIG. 6B, is therefore provided on the first upper surface 301 with a single first protrusion 302. The first protrusion 302 extends upwards from the first upper surface 301 in the height direction H up to the distance d that the cup 200 extends above the first upper surface 301. In alternative embodiments, the first protrusion 302 may however be lower or higher. The circumferential flange 220 of the cup 200, on the other hand, is provided with a single first extension 221. A first part 222 of the first extension 221 extends outwards and sideways from the circumferential flange 220, i.e. away from the cup 200 and the circumferential flange 220 in a radial or transverse direction T. A second part 223 of the first extension 221 extends downwards from the first part 222 of the first extension 221. When the cup 200 is received in the cavity 310 of the cup holder 300, such as shown in FIG. 2B and FIG. 6C, the second part 223 of the first extension 221 contacts a side of the first protrusion 302 along a rotation direction R1 around the first axis A1, such that the first protrusion 302 functions as a stop for the first extension 221 and thus the cup 220 to prevent rotation of the cup 200 in the cavity 310 of the cup holder 300. It should be remarked that the cup 200 may also be received in the cavity 310 of the cup holder 300 with the first extension 221 positioned away from the first protrusion 302 and thus not in contact with the first protrusion 302. A rotation of the cup 200 in the cavity 310 of the cup holder 300 would then move the first extension 221 towards the first protrusion 302 until the first extension 221 contacts the first protrusion 302, such as shown in FIG. 2B and FIG. 6C.

[0095] In alternative embodiments, the first extension 221 of the circumferential flange 220 can also be provided without the downwards extending second part 223, in which case it would be an edge of the first part 222 of the first extension 221 that is contacting the first protrusion 302 to prevent the rotation of the cup 200 in the cavity 310 of the cup holder 300. In combination with such embodiments it may be beneficial to provide the first protrusion 302 such that it extends upwards from the first upper surface 301 of the cup holder 300 higher than the distance d that the cup 200 extends above the first upper surface 301. This would aid in preventing the at first extension 221 of the circumferential flange 220 from accidentally slipping over the first protrusion 302.

[0096] In another embodiment of the present disclosure, the cup 200 and the cup holder 300 of the device 100 may be arranged such as shown in the FIGS. 7A-7C to prevent the cup 200 from rotating in the cavity 310 of the cup holder 300.

[0097] In this embodiment, the cup holder 300 is provided on the first upper surface 301 with a single first protrusion 302. The first protrusion 302 extends upwards from the first upper surface 301 in the height direction H over a distance which is smaller than the distance d that the cup 200 extends above the first upper surface 301. In alternative embodiments, the first protrusion 302 may also extend upwards from the first upper surface 301 in the height direction H up to the distance d that the cup 200 extends above the first upper surface 301. The circumferential flange 220 of the cup 200, on the other hand, is provided with a single first extension 221. A first part 222 of the first extension 221 extends outwards and sideways from the circumferential flange 220, i.e. away from the cup 200 and the circumferential flange 220 in a radial or transverse direction T. A second part 223 of the first extension 221 extends downwards from the first part 222 of the first extension 221. With this embodiment, the cup 200 can be received in the cavity 310 of the cup holder 300 with the first part 222 of the first extension 221 arranged over the correspondingly shaped first protrusion 302 on the first upper surface 301 of the cup holder 300, such as shown in the cross section of FIG. 7C. In this arrangement, the second part 223 of the first extension 221 contacts opposing sides of the first protrusion 302 along a rotation direction R1 around the first axis, such that the first protrusion 302 functions as a stop for the first extension 221 and thus the cup 220, which prevents rotation of the cup 200 in the cavity 310 of the cup holder 300 in opposite senses.

[0098] In this embodiment, the cup holder 300 is also provided with a second protrusion 303 which extends upwards from the first upper surface 301 of the cup holder 300 in the height direction H. The second protrusion 303 is a circumferential protrusion that surrounds the entrance opening 304 of the cavity 310 of the cup holder 300. The second protrusion 303 extends upwards from the first upper surface 301 in the height direction H over a distance which is smaller than the distance d that the cup 200 extends above the first upper surface 301. The second protrusion 303 is beneficial for supporting the second extension 224 of the circumferential flange 220 of the cup 200, for example when the second extension 224 is grabbed onto for taking the cup 200 out of the cavity 310 of the cup holder 300. In alternative embodiments, the second protrusion 303 may also extend upwards from the first upper surface 301 in the height direction H up to the distance d that the cup 200 extends above the first upper surface 301, in which case the second protrusion is also beneficial for supporting the circumferential flange 220 of the cup 200. In alternative embodiments, the second protrusion 303 can however also be omitted.

[0099] In this embodiment, the first protrusion 302 on the first upper surface 301 of the cup holder 300 extends sideways from the second protrusion 303 on the first upper surface 301 of the cup holder 300, such that the first protrusion 302 and the second protrusion 303 are linked to each other. In alternative embodiments, the first protrusion 302 may however also be separate from the second protrusion 303.

[0100] In another embodiment of the present disclosure, the cup 200 and the cup holder 300 of the device 100 may be arranged such as shown in the FIGS. 8A-8C to prevent the cup 200 from rotating in the cavity 310 of the cup holder 300.

[0101] In this embodiment, the cup holder 300 is provided on the first upper surface 301 with six first protrusions 302. In alternative embodiments, the number of first protrusions 302 may however also be lower or higher. The first protrusions 302 extend upwards from the first upper surface 301 in the height direction H over a distance which is smaller than the distance d that the cup 200 extends above the first upper surface 301. In alternative embodiments, the first protrusions 302 may also extend upwards from the first upper surface 301 in the height direction H up to the distance d that the cup 200 extends above the first upper surface 301. The first protrusions 302 are arranged rotationally symmetric around the entrance opening 304 of the cavity 310, i.e. at equal distances from each other. The circumferential flange 220 of the cup 200, on the other hand, is provided with a corresponding number of first extensions 221, which are arranged rotationally symmetric on the circumferential flange 220, i.e. at equal distances from each other. A first part 222 of each of the first extensions 221 extends outwards and sideways from the circumferential flange 220, i.e. away from the cup 200 and the circumferential flange 220 in a radial or transverse direction T. A second part 223 of each of the first extensions 221 extends downwards from the first part 222. With this embodiment, the cup 200 can be received in the cavity 310 of the cup holder 300 with the first part 222 of each of the first extensions 221 arranged over one the correspondingly shaped first protrusions 302 on the first upper surface 301 of the cup holder 300, such as shown in the cross section of FIG. 8C. In this arrangement, the second part 223 of each of the first extensions 221 contacts opposing sides of the corresponding first protrusion 302 along a rotation direction R1 around the first axis, such that the first protrusions 302 function as stops for the first extensions 221 and thus the cup 220, which prevent rotation of the cup 200 in the cavity 310 of the cup holder 300 in opposite senses. The rotationally symmetric arranged first protrusions 302 on the first upper surface 301 of the cup holder 300 and the rotationally symmetric arranged first extensions 221 on the circumferential flange 220 of the cup 200 offer the advantage that the cup 200 can be received in different positions in the cavity 310 of the cup holder 300, each position being rotated 60° with respect to each other. This makes it easier to position the cup 200 correctly and quickly in the cavity 310 of the cup holder 300.

[0102] In this embodiment, the cup holder 300 is also provided with a second protrusion 303 which extends upwards from the first upper surface 301 of the cup holder 300 in the height direction H. The second protrusion 303 is a circumferential protrusion that surrounds the entrance opening 304 of the cavity 310 of the cup holder 300. The second protrusion 303 extends upwards from the first upper surface 301 in the height direction H over a distance which is smaller than the distance d that the cup 200 extends above the first upper surface 301. The second protrusion 303 is beneficial for supporting the second extension 224 of the circumferential flange 220 of the cup 200, for example when the second extension 224 is grabbed onto for taking the cup 200 out of the cavity 310 of the cup holder 300. In alternative embodiments, the second protrusion 303 may also extend upwards from the first upper surface 301 in the height direction H up to the distance d that the cup 200 extends above the first upper surface 301, in which case the second protrusion is also beneficial for supporting the circumferential flange 220 of the cup 210. In alternative embodiments, the second protrusion 303 can however also be omitted.

[0103] In this embodiment, the first protrusions 302 on the first upper surface 301 of the cup holder 300 extend sideways from the second protrusion 303 on the first upper surface 301 of the cup holder 300, such that the first protrusions 302 and the second protrusion 303 are linked to each other. In alternative embodiments, the first protrusions 302 may however also be separate from the second protrusion 303.
