DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0037] Reference is made to FIG. 3 which shows a device comprising a cassette 1 in a supporting plate 4. As will be disclosed in further details below, the device shown in FIG. 3 may for instance be a part of a filling machine and, in particular, the supporting plate 4 may be a part of a conveyer of such a filling machine.

[0038] As shown in FIG. 3, the cassette 1 has an opening 2 in an axial direction of the cassette and has a support surface 3 transverse to the axial direction and extending around the opening 2 of the cassette 1. Thereby the cassette 1 being capable of receiving a cup (not shown) in the opening 2 with an outwardly extending flange of the cup supported by the support surface 3.

[0039] The device further comprising a supporting plate 4 having an opening in a normal direction of the supporting plate; as shown in FIG. 3, the cassette 1 is received in this opening.

[0040] The cassette comprises a resilient or flexible material. Typically and as shown in FIG. 3, the cassette is formed solely from such resilient or flexible material. Rubber is a preferred option for use of flexible material.

[0041] In order to maintain the cassette in the supporting plate, the cassette 1 comprising a slot 5 in which a part of the supporting plate 4 is received. It is preferred to dimension the slot 5 relatively to the thickness of the supporting plate 4 so that the supporting plate 4 is received in the slot in close contact without cavities. This at least mitigates the risk of build-up of contaminations in the slot 5.

[0042] In addition, the provision of the slot allows the cassette 1 to be maintained in the supporting plate when the supporting plate 4 is turned upside down which may occur e.g. when the supporting plate 4 forms part of a continuous conveyer belt.

[0043] Preferably, the close contact is established by the resilient or flexible material exerting a firm grip on the part of the supporting plate 4 being received in the slot 5. Such a firm grip is preferably dimensioned so at to provide a seal between the resilient or flexible material and the supporting plate.

[0044] While it is preferred to form the cassette only from a resilient or flexible material, a cassette may be made from a combination of materials. In such embodiments, at least the support surface 3 of the cassette 1 is formed by the resilient or flexible material. Thus, in preferred embodiments, the resilient or flexible material forms part of the cassette.

[0045] While the above disclosed cassette allows for receiving a cup or container of a certain size matching the opening 2 of the cassette 1 with the flange of the cup or container resting on the support surface 3, a production facility could benefit from being able to handle cups or container with another dimension than what the cassette 1 is designed for. In such case, the device according to the present invention may further comprise a reducing cassette 7 as shown in FIG. 4.

[0046] Such a reducing cassette 7 has an opening 10 in an axial direction of the reducing cassette 7 and a support surface 11 transverse to the axial direction and extending around the opening 10. The opening 10 of reducing cassette 7 is smaller than the opening 2 of the cassette 1 and is capable of receiving a cup or container in the opening with a outwardly extending flange of the cup or container supported by the support surface 11. As shown, the reducing cassette 7 is received in the opening of the first cassette.

[0047] As shown in FIG. 4, the reducing cassette 7 is preferably made from two parts, a first part 7a which preferably is formed by a non-resilient or non-flexible material, such as metal (e.g. stainless steel) and a resilient or flexible part formed by a resilient or flexible material such as rubber. The part 7b is referred to as a lining herein. However, the reducing cassette 7 may be formed solely from a resilient or flexible material.

[0048] The reducing cassette 7 shown in FIG. 4 comprising a slot 8 in which a part of the part of the cassette 1 comprising the support surface 4 of the cassette 1 is received. As introduced above, the reducing cassette 7 comprises a lining 7b formed by a resilient or flexible material, and the lining 7b further forms the support surface (11).

[0049] Reference is made to FIG. 5 which shows a reducing cassette 7 where no lining 7b is applied (although it is within the scope of the invention to apply such a lining 7b). In the embodiment of FIG. 5, the reducing cassette 7 comprising a latch 13 engaging with a groove 14 provided in the cassette 1 in order to maintain the reducing cassette 7 in latched position in the cassette 1. This is advantageous e.g. if the supporting plate 4 is turned upside down as disclosed above.

[0050] Preferably, the opening of a cassette 1 according to the present invention is a centrally arranged opening, which opening may be annular for receiving cups of container having a circular cross section. Further, the opening of the reducing cassette 7 is a centrally arranged opening, which may be annular. It is noted that the shape of the opening of a cassette or reducing cassette is selected to match the cross section of the cup or container to be received in the opening, and that for instance the cassette may be formed to match e.g. a cup having a rectangular cross section and the reducing cassette may be formed to match a cup with a circular cross section. In such embodiments, the outer shape of the reducing cassette 7 may be rectangular to mimic the shape of the opening 2 in the cassette 1 while the opening 10 in the reducing cassette is circular to receive a cup with a circular cross section.

[0051] In a particular preferred embodiment, the device is a filling device comprising a conveyer and a plurality of cassettes as disclosed herein and the supporting plate 4 forms at least a part of the conveyer, so that the conveyer conveys a cassette arranged in the opening of the supporting plate 4. Such a filing device may further comprise a plurality of reducing cassettes 7 as disclosed herein.

[0052] In order to allow for easy application of reducing cassettes 7 the filling may further comprise a dispenser 15 as disclosed in FIG. 6. The dispenser is typically used for dispensing a reducing cassette 7 into the opening of a cassette 1 arranged in the opening the supporting plate 4.

[0053] As shown in FIG. 6, the dispenser 15 comprising a magazine element 16 arranged with its axial direction substantially transversal to a conveying direction of the conveyer. The magazine element 16 may be formed by a number of rods, a tubular element or the like and is adapted to house the reducing cassettes 7 in a stack as disclosed in FIG. 6 so as to form a magazine of reducing cassettes 7. In FIG. 6 double arrows indicates an element's movement and hatched contours indicates another position element 17.

[0054] The dispenser also comprising a device 17 for moving a single reducing cassette 7 from a stack of reducing cassettes arranged inside the magazine element 16 into the opening 2 of a cassette 1, and for retracting a reducing cassette 7 from a cassette 1 and arranging the retracted reducing cassette 7 in magazine element 16. The stack of reducing cassettes 7 is kept inside the magazine element 16 by the stack support 18.

[0055] Although the present invention has been described in connection with the specified embodiments, it should not be construed as being in any way limited to the presented examples. The scope of the present invention is set out by the accompanying claim set. In the context of the claims, the terms “comprising” or “comprises” do not exclude other possible elements or steps. Also, the mentioning of references such as “a” or “an” etc. should not be construed as excluding a plurality. The use of reference signs in the claims with respect to elements indicated in the figures shall also not be construed as limiting the scope of the invention. Furthermore, individual features mentioned in different claims, may possibly be advantageously combined, and the mentioning of these features in different claims does not exclude that a combination of features is not possible and advantageous.
