    Description


    [0001] The invention relates to a mould and mould system for food products, of the type comprising at least one support, with an upper side comprising at least one housing defining an upper opening for placing the food product to be moulded, external legs and a lower side, wherein it comprises fixing means, in form of a pin or a latch, which attach and block the support to the external legs of an upper support, and in that the lower side is a lid of a lower support to which it is attached and blocked by means of the external legs that fit in the lower support and which are attached and blocked by respective fixing means; with the supports being identical.

    BACKGROUND TO THE INVENTION



    [0002] Different moulds are known in the state of the art which are stacked with a food product to be processed inside them.

    [0003] So, European Patent application No. 2179656 "SYSTEM FOR STACKING AND UNSTACKING MOLD UNITS", from 2009, is known, in the name of CREMONA INOXIDABLE S.R.L., which relates to a system for stacking and/or unstacking stackable units in a unit handling apparatus, wherein the system comprises a support means including a frame for taking one stackable unit from a pile of units and extracting the units, one at a time, from the stack, and for taking units provided in the system to stack them in a pile of units, and transport means for receiving stacked units and delivering unstacked units outside the system.

    [0004] Also, European Patent application No. 0292417 "STACKABLE SETS OF CONTAINERS INTENDED TO HOLD FOOD PRODUCTS DURING COOKING", from 1988 is known, in the name of ARMOR-INOX, S.A., which relates to a stackable set which has four trays placed one next to the other and joined together by the side plates. On each side, a front foot and a rear foot are welded to the outer wall of the outermost tray. Seen from the side, the feet are rectilinear and tilted, whereas, seen from the front or from behind, they have a rectilinear vertical central part and an upper part tilted outwards. On each side, the upper ends of the feet are joined by the bars and the opposing faces of the front foot and the rear foot have end stops. The set of the invention is stackable or unstackable by means of handlers.

    [0005] It is worth to mention French Patent application No. 2485884 "ASSEMBLAGE DE PRESSAGE DE MOULES A JAMBONS", from 1980, from the firm ARMOR-INOX, S.A., which relates to a mould pressing set wherein the bottom of the mould box serves as the lid for the mould placed directly beneath.

    [0006] Finally, there is in the state of the art, French Patent application 2453791 "BOX PALLET SECURING DEVICE - WITH SLEEVES STACKED ON PALLET AND SECURED BY OPPOSED HOOKED MEMBERS CONNECTED BY PIVOTAL LEVER MECHANISM AND LATCH", from 1979, in the name of Kenneth JOHANSSON et al., which relates to one or several square or rectangular, box-like, bottomless elements that are stacked one on top of another on a pallet. The elements have a hook and they are connected by the link and the rotating lever. The element's hook is U-shaped and it is applied to the upper edge of a wall of the upper box. The element's hook is L-shaped and it couples under the pallet platform. The lever turns upwards to drag the elements together, so that they are blocked by means of a latch, securing the boxes to the pallet.

    [0007] French Patent application FR 2 882 630 discloses a mould for food products according to the preamble of claim 1.

    BRIEF DESCRIPTION OF THE INVENTION



    [0008] This application falls within the sector of moulds for food products.

    [0009] In this invention the terms "supports" and "moulds" will be used in an equivalent manner.

    [0010] Traditionally a cell system has been used to store the moulds and mould the food product arranged in a housing inside them.

    [0011] It comprises structures that include decks where each of them has a space for placing the mould and then a pressing element that compresses the food goes down from the roof of said deck.

    [0012] This type of structures suffers essentially from the drawback of cleaning of the pressing elements, which leave corners that cannot be cleaned, and this is a source for bacterial contamination.

    [0013] Other manufacturers have moulds that end up entering some stockpot with an upper lid that closes the stockpot and which in turn presses the moulds downwards.

    [0014] The drawback lies in the fact that it can only be used in case when the stockpot is full and with this system you cannot use oven cooking.

    [0015] Finally, in general they all suffer from a problem regarding storage space, since they need to be kept in large facilities.

    [0016] European Patent No. 0292417. solves the problems because the moulds can be washed without any problem, they can be stored by stacking them, a smaller amount of moulds can be used because it is not necessary for the stockpot lid to press and the oven can be used.

    [0017] The problem is that the fixing system between moulds is under pressure, which prevents lifting them upwards, using a lifting means.

    [0018] Even if a system were designed to attach some to others, in view of what is known, it cannot be automated, due to difficulties with the mould-release system.

    [0019] Therefore, the inventor has proposed a system wherein the moulds are blocked against one another by means of a latch or pin-like system, so that when the upper mould fits onto the lower one, a pin or latch in the lower mould is activated, which blocks the upper mould.

    [0020] The invention relates to a mould for food products according to claim 1.

    BRIEF DESCRIPTION OF THE DRAWINGS



    [0021] In order to facilitate the explanation, five sheets of drawings are attached to this specification, which represent a practical embodiment thereof that is shown as a non-limiting example of the scope of this invention:
    • Figure 1 is a general view of a mould that is the object of this invention,
    • Figure 2 is a view of two mounted supports,
    • Figure 3 is a sectioned view of Figure 2, along the line III-III,
    • Figure 4 is a sectioned view of Figure 2, along the line IV-IV,
    • Figure 5 is a general view of the stacking of the moulds

    SPECIFIC EMBODIMENT OF THIS INVENTION



    [0022] Thus, Figure 1 illustrates a first support 1, with its upper side 2 and its lower side 3, exterior legs 4, fixing means 5, handles 6, and a housing 7.

    [0023] Figure 2 represents first support 1 with its upper side 2, its exterior legs 4 and its fixing means 5, handles 6, a lower support 11 with its legs 21, its fixing means 15 and a through hole 12.

    [0024] Figure 3 shows first support 1 with its upper side 2, its lower side 3 and its exterior legs 4, fixing means 5, 15, handles 6, housings 7, and lower support 11 with its legs 21.

    [0025] Figure 4 illustrates first support 1 with its upper side 2 and its exterior legs 4, fixing means 5, 15, handles 6, housings 7, and lower support 11 with its legs 21 and through hole 12.

    [0026] Lastly, Figure 5 illustrates first support 1 with its exterior legs 4, fixing means 5, handles 6, lower support 11 with its legs 21, fixing means 15 and through hole 12 and an upper support 20, with its legs 22.

    [0027] The mould for food products, comprises at least one support 1, with an upper side 2 comprising at least one housing 7 for housing the food product, which defines an upper opening 2 for placing the food product to be moulded.

    [0028] It also has external legs 4 and a lower side 3.

    [0029] The mould comprises fixing means 5, like a pin or latch, which attach and block it to legs 22 of lower support 20, when the second one is placed over the first support 1.

    [0030] If the first the mould 1 is placed over a lower mould 11, fixing means 15 of lower mould 11, like a pin or latch, which will attach and block it to legs 4 of first support 1, leaving a set of compact moulds, as one piece, which can be transported without problems, without a risk of being opened.

    [0031] Also, lower side 3 of first support 1 is a lid of lower support 11, in other words, when first support 1 fits onto support 11, lower side 3 of first support 1 blocks the upper opening of second support 11, acting as a lid for said second support 11, and preventing that foreign bodies can access the interior of second support 11.

    [0032] As explained above, in order to increase the cohesion, external legs 4 of first support 1 fit into lower support 11, so that together with the blocking of the fixing means 15 of lower support 11 through hole 12 in first support 1, they allow forming a set as one piece. Lower support 11 also has another through hole 12 in legs 21, which would be used with a support that were placed beneath it and its fixing means would pass through said through hole 12.

    [0033] Optionally it has been envisaged that supports 1, 11 comprise handles 6. Said handles 6 are an important element because, if a robot moves the unit of stacked supports by handles 6, hanging in the air, from upper support 20, it allows lifting the whole set of supports 1, 11, 20 at the same time, facilitating the transport thereof and movement from one place to another.

    [0034] The mould stacking system for food products, comprises at least two supports for food products a first one 1 and a second lower one 11 (Fig. 2).

    [0035] Both supports include an upper side 2 which with at least one housing 7 that defines an upper opening for placing the food product to be moulded, and a lower side 3.

    [0036] First support 1 lies on the lower one 11 blocking the upper opening of lower support 11 and making lower side 3 of first support 1 the lid of said upper opening of lower support 11.

    [0037] Also, supports 1, 11 are attached and blocked together by means of fixing means 15 like a pin or latch, located on lower support 11, which attach and block it to legs 4 of first support 1 blocking both supports, and this way it leaves a compact structure as one piece.

    [0038] Supports 1, 11 are identical.

    [0039] One of the constructive options is that fixing means 5, 15 are retractile devices with a blocking latch, like the ones shown in Figure 4, which enter a through hole 12 and being retained. This means that by using a mechanism that exists in another machine that shifts the latch in the opposite direction, it could be possible to robotise the mould stripping and allow supports 1, 11 to be released.

    [0040] It could also be possible to use a pin type system for this.

    [0041] As indicated above, supports 1, 11 can include handles 6 that facilitate the fact that when there are different supports stacked, due to the firmness of fixing means 15, it is possible to lift up the set by handles 6 of the first support, using a crane, for example, by handles 6 of the one that has no food to mould and which only acts as a lid.

    [0042] When more supports are added, it will include an upper support 20, identical to the other two 1, 11, which fits in first support 1, with its lower side being the lid of the opening of first support 1 and with fixing means 5 of first support 1 fitting into legs 22 of said upper support 20. This way, if supports 1, 11 are lifted up, they remain joined together and as explained above, the compact set can be shifted or moved, hanging, without the problem of them possible separating.

    [0043] This invention describes a new mould and mould stacking system for food products. The examples mentioned herein are non-limiting regarding this invention, and therefore it can have different applications and/or adaptations, all comprised within the scope of the following claims.
