  • Patent number: 9968070
    Abstract: A press cover for a cheese mold, in particular for a cheese mold of metal, having a round or polygonal cross section. The shape and dimensions of the press cover correspond to the inner cross section of the cheese mold. The press cover is to be designed in a simple manner, to withstand a press power, and also to satisfy high hygiene demands. This is achieved in that the press cover includes a perforated plate, the shape and dimensions of which corresponds to the inner cross section of the cheese mold, on which a reinforcing rib structure is arranged.

  • Patent number: 9713314
    Abstract: The invention relates to a press cover for a cheese mold, particularly for a cheese mold (1, 12) made from metal with a round or polygonal cross section, wherein the shape and dimensions of the press cover (1) match the inner cross section of the cheese mold (1). It should be of simple construction, able to withstand high pressing force, and also satisfy stringent hygiene requirements. This is solved in that the press cover (1) comprises a perforated plate (22) and a frame (30) with is provided on the periphery of the press cover (21), which frame has a movable outer ring (33) arranged on the outside thereof, which ring lies flush against the inner wall of the cheese mold (1, 12) and creates an effective seal therewith when the raw cheese mass is pressed out. The press cover (21) is also provided with a stiffening frame and rib structure (23, 24, 30).

  • Patent number: 9049837
    Abstract: The invention provides a cheese mold, in particular a cheese mold composed of plastic or metal, for arrangement in a cassette press or the like. The mold should have a simple structure, and at the same time withstand the pressing pressure and also satisfy high hygienic demands. This is advantageously achieved in that the base of the mold is provided with a rib structure as far as the transition region of the outer jacket wall, wherein the mold can be round or cylindrical or angular in cross section. In the case of a round mold, longitudinal ribs extend radially, starting from the longitudinal axis over the base and continuously as jacket ribs into the region of the jacket wall.

  • Patent number: 8916221
    Abstract: A method for producing cheese and a device therefore, in particular what is known as a cassette press with round or angular cheese molds. The method is intended in particular to achieve gentle and hygienic de-molding of the cheese blocks after removal of whey. A raw cheese mass is first poured into molds of a cassette press, then pressed to remove liquid and emptied out of the mold after a turning process. Directly after turning, the raw cheese mass in the mold is subjected to a shaking movement, so the pressed raw cheese mass is detached gently from the inner wall of the mold.

  • Publication number: 20070262127
    Abstract: A container has an article, such as a tray, and a sleeve wrapping the article. The sleeve has a first panel having an opening with a locking edge. A second panel of the sleeve has an interior cut line terminating at either end in a hinge line. The cut line has a section offset from the hinge line such that hinging the second panel about the hinge line extends a locking tab. The locking tab of the second panel locks to the locking edge of said first panel and an adhesive adheres an area of the second panel registered with the opening to the article.

  • Patent number: 6726088
    Abstract: The top of a carton, with opposite main panels and opposite side panels, has an inner and outer major flap hinged to opposite main panels. The outer major flap has a fold line extending along its length in parallel to a hinge line joining the outer major flap and a main panel. At each side panel, an ear has an ear portion hinged to the side panel and an ear portion hinged to the outer major flap. With this arrangement, the carton may be re-closed by pressing the ears down against the outer major flap so that the outer major flap folds about fold line into a concave V-shape.

  • Patent number: 6520404
    Abstract: The top of a carton, with opposite main panels and opposite side panels, has an inner and outer major flap hinged to opposite main panels. At each side panel, an ear has a lower portion hinged to the side panel and two upper ear-halves, one hinged to each of the major flaps. To seal the top, adhesive is applied to an outer face of the inner major flap and to the ear-halves extending from either end of one of the major flaps, usually the inner major flap. Then the inner major flap is folded down and the ear-halves extending therefrom are folded down and out. The outer major flap with extending ear-halves is folded on top in overlapping relation so that the adhesive bonds. In one aspect, each ear has a notch between the ear-halves to facilitate overlapping of the ear-halves. With the carton blank coated with an impermeable coating, the resulting carton is air tight.
