Definitions

  • the present invention belongs to the field of dairy product packaging.
  • the object of the present invention in particular is a packaged dairy product, e.g. mozzarella.
  • the prior art includes some different types of packages also comprising, in addition to the mozzarella, a preserving liquid in which the mozzarella is partially submerged.
  • An example of packaged dairy products is disclosed in prior art document WO 2017/191296 A1 .
  • An example of a flat bottom pillow pouch package for dry snack food is disclosed in US 2012/055120 A1 .
  • a first known type of package is the "Brick" type ( Figure 1 ) package, provided with a square shape, which allows it to remain stably in a vertical position.
  • the prestige resulting from being a compact and stable package is also the greatest limitation thereof because the rigidity of the Brick allows it to be transported and stored only while keeping it in such a vertical position.
  • a second known type of package is the "Pillow” package in the two “flat Pillow” ( Figure 1a ) and “Pillow with Tuft” variants ( Figure 1b ).
  • the Pillow packages both in the Flat Pillow and the Pillow with Tuft variants, are made of a flexible material which is deformed when it comes into contact with a supporting surface or if gripped by a user.
  • the mozzarella is substantially to be submerged in the preserving liquid and the weight ratio between the mozzarella and the preserving liquid is to be 1:1.
  • a third type of package is the "Tub" ( Figure 1c ) made of a rigid polymeric material, and therefore which is not deformed when touched by a user or when it comes into contact with a supporting surface.
  • the rigidity of the tub is due to the thickness of the polymeric material with which it is made. Such a thickness is between about 700 and 1000 microns and requires the use of a significant amount of polymeric material. The non-negligible use of such a polymeric material results in just as significant an impact on the environment. Moreover, due to the rigidity thereof, the tub may only be transported by keeping it upright and not resting on a side.
  • a fourth type of package is the "Doypack" ( Figure 1d ) package made of a flexible material, but provided with a support base.
  • the Doypack package is flexible and therefore it does not allow the mozzarella to be kept substantially submerged with an optimal weight ratio of 1:1 between mozzarella and preserving liquid.
  • the flexible packages do not allow the simultaneous fulfilment of the two requirements of optimal preservation, i.e. mozzarella substantially submerged in the preserving liquid and weight ratio of 1:1 between the mozzarella and the preserving liquid; instead, the rigid packages, or packages provided with support base, have a single preferential transport and storage direction.
  • a further disadvantage of the flexible packages results from the fact that they are positioned on the supermarket shelves by stocking staff operating quickly, often heedless of the fact that there is or is not a preferential direction in which the package should be displayed.
  • the object of the present invention is to propose a packaged dairy product so that a plurality of display configurations on the shelf are possible.
  • Numeral 1 in said drawings indicates a packaged dairy product and numeral 100 indicates a packaging machine of such a packaged dairy product.
  • the packaged dairy product 1 comprises a packaging envelope 2, a preserving liquid 3 and at least one dairy product 4, e.g. mozzarella.
  • the packaging envelope 2 contains the preserving liquid 3 in which the at least one dairy product 4 is at least partially submerged.
  • the packaging envelope 2 consists of a pair of main walls 21, 22 opposite to each other, and a pair of side walls 23, 24 arranged between and connected to such main walls 21, 22.
  • the two side walls 23, 24 face each other and space the two main walls 21, 22 apart from each other.
  • the main walls 21, 22 have respective main wall end portions 21', 21"; 22', 22" facing one another, converging with one another and ending with respective first main wall edges 211', 211"; 221', 221” welded together.
  • each main wall 21, 22 is laterally delimited by second main wall edges 212', 212"; 222', 222", opposite to one another and extending between the first main wall edges 211', 211"; 221', 221".
  • a first main wall 21 is delimited by two first main wall first edges 211', 211", opposite to each other, and by two first main wall second edges 212', 212" connecting such first main wall first edges 211', 211".
  • the first main wall 21 further comprises two first main wall end portions 21', 21", each obtained close to the corresponding first main wall first edge 211', 211".
  • a second main wall 22, opposite to the first is delimited by two second main wall first edges 221', 221", opposite to each other, and by two second main wall second edges 222', 222" connecting such second main wall first edges 221', 221".
  • the second main wall 22 further comprises two-second main wall end portions 22', 22", each obtained close to the corresponding second main wall first edge 221', 221".
  • Each first main wall end portion 21', 21'' converges towards a respective second main wall end portion 22', 22" so as to form two pairs of main wall end portions which are adjacent to each other.
  • the side walls 23, 24 are delimited by side wall edges 231', 231"; 241', 241, opposite to one another and welded to the respective second main wall edges 212', 212"; 222', 222".
  • Each side wall 23, 24 further comprises side wall end portions 23', 23"; 24', 24" opposite to one another, folded towards the inside of the packaging envelope 2 and also welded to the respective first main wall edges 211', 211"; 221', 221".
  • a first side wall 23 is delimited by first side wall edges 231', 231" which are opposite to each other.
  • the first side wall 23 further comprises first side wall end portions 23', 23" folded towards the inside of the packaging envelope 2 and also welded to the respective first main wall edges 211', 211"; 221', 221” so as to form a pocket or a concavity facing the outside of the packaging envelope.
  • a second side wall 24 is delimited by second side wall edges 241', 241" which are opposite to each other.
  • the second side wall 24 further comprises second side wall end portions 24', 24" folded towards the inside of the packaging envelope 2 and also welded to the respective first main wall edges 211', 211"; 221', 221” so as to form a pocket or a concavity facing the outside of the packaging envelope.
  • the weight ratio between the preserving liquid 3 and the at least one dairy product 4 is about 1:1. Therefore, the dairy product 4 minimizes the release of water suitable for balancing the salt level with the preserving liquid 3 through an osmotic process.
  • the packaging envelope 2 is made of a material and/or has a thickness such that it is deformable when the packaged dairy product 1 is placed in contact with a supporting surface S.
  • Each of the two main walls 21, 22, each of the two side walls 23, 24 and each of the two adjacent pairs of the main wall end portions welded together along the respective first main wall edges alternatively form a stable supporting base B when placed in contact with the supporting surface S, as a result of the weight of the preserving liquid 3 and at least one dairy product 4.
  • the two main walls 21, 22 are identical to each other.
  • the two main walls are interchangeable with each other, apart from possible labels or graphic elements differentiating them.
  • the two side walls 23, 24 preferably are identical to each other. In other words, the two side walls are interchangeable with each other, apart from possible labels or graphic elements differentiating them.
  • Figure 2 shows a first transport, storage and/or display configuration of the packaging envelope 2, in which one of the two adjacent pairs of main wall end portions is welded together along the respective first main wall edges and defines a supporting base B resting on the supporting surface S.
  • the packaging envelope 2 is arranged "upright" and the at least one dairy product 4 is substantially submerged in the preserving liquid 3.
  • Figure 3 shows a second transport, storage and/or display configuration of the packaging envelope 2, in which one of the two side walls 23, 24 sags due to the effect of the weight of the preserving liquid 3 and of the at least one dairy product 4 and defines a supporting base B resting on the supporting surface S.
  • the packaging envelope 2 is arranged "on its side” and the at least one dairy product 4 is substantially submerged in the preserving liquid 3.
  • Figure 4 shows a third transport, storage and/or display configuration of the packaging envelope 2, in which one of the two main walls 21, 22 sags due to the effect of the weight of the preserving liquid 3 and of the at least one dairy product 4 and defines a supporting base B resting on the supporting surface S.
  • the packaging envelope 2 is arranged "on its front (or on its back)" and the at least one dairy product 4 is substantially submerged in the preserving liquid 3 for at least 55% of the volume thereof.
  • the packaging envelope 2 preferably is formed of a film 5 made of a polymeric material or of a biopolymer.
  • film 5 comprises a single-layer film or a multi-layer polymeric film.
  • the film is multi-layer polymeric, it preferably comprises polypropylene, polyamide and polyethylene.
  • film 5 has a thickness between about 60 and 110 microns.
  • the packaging envelope 2 is obtained from a film 5 comprising a multi-layer polymeric film, which comprises polypropylene, polyamide and polyethylene.
  • the packaging envelope 2 is obtained from a film 5 comprising a single-layer polymeric film.
  • the packaging envelope is recyclable.
  • film 5 comprises a biopolymer, i.e. a biodegradable or compostable polymer.
  • the packaging envelope is recyclable or compostable.
  • the welding between the respective first main wall edges 211', 211"; 221', 221" comprises at least two primary heat-sealing wires 200.
  • the welding between the side wall edges 231', 231"; 241', 241" and the respective second main wall edges 212', 212"; 222', 222" comprises at least one secondary heat-sealing wire.
  • At least one of the side wall end portions 23', 23"; 24', 24" folded towards the inside of the packaging envelope 2 is movable between a packaged position, in which the packaging envelope is sealed, and an open position, in which the side wall end portion is separated from the weld between the respective first main wall edges and faces outwards so as to create an opening spout 200' suitable for pouring out the preserving liquid 3 ( Figure 2a ).
  • machine 100 for packaging a packaged dairy product comprises a forming collar 6, a forming tube 7, a plurality of vertical welders 8 and at least one horizontal welder 9.
  • the forming tube 7 is of a substantially cylindrical shape and internally delimits a cavity suitable for the passage of the preserving liquid 3 and the at least one dairy product 4.
  • a forming tube 7 is further provided with a plurality of ribs 70, preferably four, protruding externally and arranged symmetrically relative to a forming tube axis T.
  • Such ribs 70 preferably are parallel to the forming tube axis T.
  • the at least one horizontal welder 9, preferably two, is arranged downstream of the forming tube 7 and is suitable for welding between the respective first main wall edges 211', 211"; 221', 221".
  • the packaging machine of a packaged dairy product 1 preferably further comprises a hopper 10 arranged upstream of the forming tube 7 and suitable for conveying the at least one dairy product 4 into the cavity of the forming tube 7.

  • Film 5 is fitted about the forming tube 7 and then folded by means of the ribs 70 which protrude externally from the forming tube 7 and are arranged parallel to the forming tube axis T.
  • the ribs 70 fold film 5 and prepare it for the welding.
  • the side wall edges 231', 231"; 241', 241" are welded with the respective second main wall edges 212', 212"; 222', 222" in order to define the pair of main walls 21, 22 and the pair of side walls 23, 24.
  • a first edge of the first main wall 211' is welded together with a corresponding first edge of the second main wall 221'.
  • the preserving liquid 3 and at least one dairy product 4 are introduced into the packaging envelope 2.
  • the other first edge of the first main wall 211" is welded together with the other corresponding first edge of the second main wall 221".
  • the packaged dairy product, the machine and the method for packaging such a packaged dairy product achieve the set object.
  • the dairy product may be displayed in any of the three transport, storage and/or display configurations, therefore there is no need to pay special attention to positioning the product on the shelf because the weight of the preserving liquid and the at least one dairy product deform the packaging envelope so that it takes on one among the three possible configurations.
  • the ratio between the preserving liquid and the at least one dairy product is 1:1, therefore the dairy product does not oxidize and the release of water into the preserving liquid is minimized.
  • the shelf-life of the packaged dairy product is longer or in any case comparable with the one of mozzarella packages according to the prior art because there is a need for the dairy product to be submerged in the preserving liquid so it does not deteriorate; indeed, in this regard, the dairy product is substantially submerged in the first and in the second configuration.
