Abstract

A bag 1 for packaging and display of fresh mozzarella cheese in conservation liquid, is made from transparent multi-layer laminated plastics material having an intermediate heat seal separating a top part 2 from a bottom part 3 substantially in the shape of a flat bottomed parallelpiped. A neck tie 4 is applied in correspondence with the heat seal and a cardboard label 5 or the like is fixed by means of said tie 4. The plastics material is nylon/polyethylene. The cheese within the bag is covered by a protective wrapping of multi-layer paper/polyethylene material perforated to allow contact with the conservation liquid. <IMAGE>

Description

BAG FOR PACKAGING AND DISPLAY OF FRESH MOZZARELLA CHEESE FORMS IN THEIR CONSERVATION LIQUID DESCRIPTION The present invention relates to a bag for packaging and display of fresh mozzarella cheese forms in their conservation liquid.

It is a well-known fact that to preserve afresh mozzarella cheese properly, it is necessary to pack it with particular, care. Contact with the air and with atmospheric dust are in fact liable to damage its organoleptic characteristics.

To prevent this problem, the state of the art provides bags giving the simultaneous presence o- the mozzarella cheese and the liquid in which it is conserved. However, this method of packing gives the problem of a high level of structural flexibility, due to the low rigidity of the material with which the bag is made. This fact means that the solution is a low duality one, due to the poor presentation of the product and the impossibility of displaying a large number of samples of the same product close together without running the rtsk of altering it-s shape.

In order to solve the problems mentioned above, the present invention proposes at the same time a better form of packing, and a more effective form of display capable of maintaining the structural integrity of the pack.

The object of the present invention is therefore a bag for packaging and display of forms of mozzarella cheese in the presence of their conservation liquid, characterised by the fact that said bag is trade ~. multilayer laminated nylon/polyethylene material, fcld-- an heat sealed, and containing a form of mozzarella cheese along with a measured amount of said conservation liquid; said bag being furthermore characterised by the fact that said multi-layer laminated nylon/ polyethylene material is transparent, in order to render the inner wrapping and the conservation liquid visible, said bag having an intermediate heat seal distinguishing a top part from a bottom part substantially in the shape of a flat bottomed parallelpiped.

The invention will now be described in greater detail according to a preferred embodiment thereof, and with reference to the enclosed drawings, in which: figure 1 shows a perspective view of the bag according to the present invention; and figure 2 shows a plan view of the multi-layer laminated material used to form the bag.

In said figures, the same reference numbers will be used to indicate the same parts.

With reference to figure 1, the bag 1 as a whole is shown in a perspective view in its display position, in which, in correspondence with the heat seal 14, indicated in the following figure 2, which separates a top part 2 from a bottom part 3 substantially shaped like a flat bottomed parallelpiped , a neck tie 4 is applied, said neck tie being for preference of plastic material with a reinforcement in double stranded metal wire. The neck tie forms the neck and the resulting flared shape of the top part, and a label S made of cardboard or the like is fixed by means of said neck tie.

The base 5 is flat and heat sealed as can be seen from edge 7.

Figure 2 is a plan view of a film obtained from a roll of multi-layer plastic material used to form the bag, in which the vertical dotted lines 8, 9, 10, 11 vindicate the edges along which the bag is folded, with the right outside edge 12 of the sheet folding over to cverlap the left edge 13 of the same; the striped area 5, and likewise the area 6 and the striped and dashed area 7 represent, respectively, the label area, the base and the edge indicated in the preceding figure 1; the horizontal strip 14 shows the area of the neck heat seal separating the top part 2 from the bottom part 3, while the area indicated with double diagonal stripes 15 can carry indications for the consumer buying the product.

In the manufacturing process a first protective packing, in direct contact with the mozzarella cheese, is preferably made of multi-layer paper/polyethylene material. This material is machine formed according to known methods, and is for preference a flow-pack of paper/polyethylene of approximately 80 g/m2 total weight, perforated, to allow the mozzarella cheese to remain in contact with the conservation liquid.

The product, wrapped as above, is packed in the bag according to the present invent ion, formation cf whic 5 carried out by machine starting from a roll of multilayer material.

Said formation is performed by means of known methods, for example using a vertical packing machine which: - starts from a roll of nylon/polyethylene ms layer material with an overall thickness cf - frms the side walls of the bag, subsequently sealing said material; - farms and subsequently seals the flat base 6; - inserts the mozzarella cheese wrapped in its first protective coat; - doses the conservation liquid; - closes the bag by heat sealing along the horizonta line 14 at a height from the flat base of the bag equivalent to approximately 2/3 of the overall height of the bag; - cuts the bag and finally off-loads it in a vertical position.

In a further step of sald manufacturing process, carried out using a clipping machine, connected and timed to operate in combination with said vertical packing machine preferably by means of a conveyor, the following operations are performed: - forming of the typical "top-knot" characterising the flared top part 2 of said bag 1; - fixing a label 5, in a preferred embodiment made of cardboard with colour printing; - final application of the neck tie 4 in correspondence with the heat seal, said neck tie also being suitable to carry the sell by date and being made of plastic material with rei-n=orcements in double stranded metal wire.

Given the shape of the finished bag it is possible to arrange a number of samples cf the same product one beside the other, without in this way prejudicing the structral characteristics of the came; finally, the transparency of the material itself renders the contents visible, thus allowing direct control by the consumer.

It is thus possible to produce on an industrial scale bags capable of standing in a vertical position by themselves.
