2. The press cover according to claim 1, wherein press cover is made of steel.

3. The press cover according to claim 1, wherein the steel is a stainless steel.

4. The press cover according to claim 1, wherein on the perforated sheet side facing away from the rim at least three hooks are arranged along a press ring or close to a longitudinal axis.

5. The press cover according to claim 4, wherein the perforations are provided on the perforated sheet except for regions in which the at least three hooks are arranged.

6. The press cover according to claim 1, wherein the perforations are in the form of cylindrical, conical or stepped bores.

7. The press cover according to claim 1, wherein each of the perforations has a hole diameter of 0.6-1.2 mm and wherein the perforations are arranged at a distance of 2-3 mm from one another.

8. The press cover according to claim 1, wherein the perforated sheet has a height of the rim of 8-10 mm.

9. A combination comprising the press cover according to claim 1 and a cheese mould, wherein the cheese mould has a base and side walls, and wherein the cheese mould is round or respectively cylindrical or polygonal.

10. The combination according to claim 9, wherein at least two polygonal cheese moulds are arranged as a cassette, the cheese moulds connected by means of a cover sheet and transverse ribs arranged close to the base, and wherein the cassette further has longitudinal ribs on the base and/or casing ribs in the region of the side walls.

11. A method for the production of a press cover for a cheese mould which consists of metal and comprises a one-walled perforated plate, wherein the perforated plate is produced in the form of a perforated sheet with a circumferential, bent rim by deep-drawing, into which subsequently a plurality of perforations are worked in.

DETAILED DESCRIPTION

[0037] A press cover 1 according to the invention (FIG. 1), in the example for a round cheese mould (not illustrated), comprises a one-walled, circular perforated sheet 2, which in its cross-section corresponds to the interior cross-section of the cheese mould (likewise circular). The perforated sheet 2 is polished at least on the side facing the pressing direction.

[0038] The perforated sheet 2 has a plurality of perforations 4 (FIG. 9) and, in the example, a circumferential, bent rim 3 of for example a height h of 10 mm and a radius r of ca. 8 mm. The rim 3 is bent in pressing direction 9 and, on the pressing out of whey, lying closely against the inner wall of the cheese mould. In another embodiment, the perforated sheet 2 can also be provided with a straight rim (FIGS. 4 and 5).

[0039] Such a perforated sheet 2 is able to be produced economically by means of deep-drawing.

[0040] On the perforated sheet 2, with a round formation of the press cover 1, three hooks 5 are arranged, spaced apart from one another uniformly along a (virtual) press ring 7, on the side facing away from the pressing direction or respectively the cheese mould (FIG. 1, 3).

[0041] With a four-sided press cover 10 (FIG. 6), the hooks 5 in the example are arranged both centrally along a longitudinal axis of the press cover 10 and also, close to the narrow sides, to the left and right adjacent to the longitudinal axis.

[0042] The hooks 5 serve in a known manner for receiving the press cover 1 on a press head of a cheese press and direct the press frame onto the perforated sheet surface.

[0043] A region 6 around the hooks 5 is free of holes.

[0044] In the example, the perforations 4 are embodied as stepped bores 8 (FIG. 2, 9). In the example, the larger hole diameter is preferably 1.2 mm and the smaller hole diameter 0.8 mm. Smaller hole diameters are less well able to be cleaned. The individual bores 8 are arranged at a distance of a few millimetres, preferably 2-3 mm, from one another.

[0045] FIGS. 7 and 8 show a four-sided, cuboidal cheese mould 11, which has a base 12 and side walls 13, wherein the base 12 and the side walls 13 are formed from the previously described perforated sheet 2.

[0046] In the example, in addition, four of these cheese moulds 11 are arranged together as a cassette 18, wherein the cheese moulds 11 are connected by means of a cover sheet 17 and transverse ribs 16 arranged close to the base. In the example, the transverse ribs 16 are arranged on two outer side walls standing parallel to one another. The cassette 18 which is thus formed has furthermore, for reinforcement, longitudinal ribs 14 on the base and casing ribs 15 in the region of the side walls, which are respectively arranged parallel to one another.

[0047] A further round cheese mould in a cheese press, with which the press cover 1 according to the invention corresponds, is disclosed for example in the applicant's EP 2845469 A1. It comprises a cylindrical casing with an upper basket and a base.

[0048] For cheese which is to be high-pressed, i.e. hard cheese, the casing wall and also the base consist of perforated sheet. In the pressing out of soft cheese or semi-hard cheese, on the other hand, a conventional perforation can be sufficient.
