Description

    Field of the Invention
  • The present invention concerns a pizza packaging of the kind specified in the introduction of claim 1.
  • Background of the Invention
  • A traditional pizza packaging consists of a flat folding box which is often made of cheap recycled cardboard, and which in connection with preparation - folding the flat foldable boxes - demands extensive and relatively time-consuming work. Besides, this manual handling may constitute a risk of contamination by touch.
  • The busy periods in pizza bakeries are of course concentrated around eating times, i.e. lunchtime from 11 to 14 and dinnertime from 17 to 21. Prior to these busy periods, the staff prepares/folds a very large number of flat folding boxes which in the folded up condition, i.e. with folded and fixed box part and with open lid, are placed in high stacks.
  • It is thus very normal that almost any table or disk face of a pizza bakery close to the mentioned busy periods are filled with high stacks of frequently hundreds of folded up and prepared pizza boxes.
  • In other words, much work time and storage space is used for preparation and folding up of prior art pizza boxes of cardboard so that the subsequent packing of baked pizzas and distribution thereof can be made as efficient as possible.
  • However, pizza consumers are conscious of hygiene and environment and aware of any possible health risk. It has appeared that the type of recycled cardboard used extensively for making pizza folding boxes may contain residues of heavy metals and other hazardous substances that may present a food safety hazard.
  • A possible alternative may be using a cleaner and more expensive cardboard or fibre material for making the popular flat folding boxes for pizzas, however implying a considerable increase in the cost of the known folding pizza boxes.
  • Auxiliary request amendments - replacement sheets - 09.05.2016
  • Moreover, the food authorities recommend that fibre-based materials in general are not used for direct contact with food.
  • US 2003/0127462 A1 discloses a transportable packaging system for products that are best carried in a horizontal position and that require spaced, non crushable stacking. It is useful in the food industry as packaging for pizza, heated fast-food items, salads, deli products, and bakery goods.

  • BE 1 106 104 A3 discloses a container for transporting warm pizzas, the container has a polyolefin coating on at least one of its inside walls in order to keep the pizza warm. The bag-shaped container for transporting warm pizzas comprises flat front and rear walls connected to each other by side walls with a harmonica fold construction so that the bag con be folded flat or opened up in order to insert or take out the pizza. Further is disclosed a transportable stack of pre-formed bag-shaped pizza transport containers and a method for making pizza transport containers by coating a web, applying adhesive, folding the web, joining two length sides together to form a length direction joint, producing loose containers from the web and closing one end of each loose container.
  • Object of the Invention
  • On this background, the object of the invention is to indicate a new and improved pizza packaging which by means of relatively simple means enables counteraction of the above mentioned problems by the prior art pizza packagings.
  • Description of the Invention
  • The pizza packaging according to the invention is characterised in that said bag packaging includes a lower support member consisting of a plate-shaped rigid material, that said lower support is disposed at the inner side of the lower part and fastened to the latter and that said support member is constituted by a flat piece of plastic, e.g. polypropylene, which at the top side along its periphery is designed with upright, upwardly tapering support columns, the pointed ends of which being adapted to engage complementarily designed recesses in the bottom side of a corresponding flat plastic piece.
  • By means of relatively simple means it hereby becomes possible to counteract the above mentioned problems connected with the work of folding up the prior art pizza packagings in the shape of flat folding boxes of cardboard.
  • Besides, an acknowledged problem by using the prior art flat pizza boxes of cardboard is avoided while at the same time eliminating cardboard dust and small cardboard pieces whirling around in the pizza bakery when the pizza boxes are assembled. As an important extra benefit, the disagreeable taste of cardboard in the pizza is eliminated at the same time.
  • Auxiliary request amendments - replacement sheets - 09.05.2016
  • Irrespective of the support member being placed inside or outside of the bag packaging, it may be advantageous that said support member is made from the same type of plastic material as the bag film, e.g. polypropylene, since hereby it will be very easy to fix the support member to the plastic film by means of an appropriate number of weld points.
  • It may be advantageous to design the pizza packaging according to the invention such that the inner support member is constituted by a plastic disc with a plane centre surface of about the same size as a pizza and with an annular edge part sloping upwards/outwards. Hereby is achieved the extreme advantage that the pizza can be enclosed by the annular edge part which provides lateral support when stacking several bag-packed pizzas.
  • The pizza packaging according to the invention may further be designed such that said the upper part is constituted by a plastic film with encapsulated metal coating. Hereby it becomes possible to achieve a further important advantage by a bag-packaging according to the invention since the metallised bag will contribute to keeping the pizza warm for a longer time than in the common pizza packaging.
  • On the other hand, the pizza packaging according to the invention is advantageous such that said upper part at least in an edge area outside a circular centre area with a size corresponding to that of a pizza is designed with a large number of micro-perforations, such that the pizza will avoid being unnecessarily soft and spongy.
  • With the intention of facilitating removal of the pizza, or taking a piece of the pizza, the pizza packaging according to the invention may advantageously be designed such that the upper part is designed with a circular central tearing field with a size corresponding to that of a pizza and with a gripping tab disposed centrally in the opening, the tearing field including gripping tab being formed by a series of annular perforations.
  • The pizza packaging according to the invention is suitably provided in varying sizes at least corresponding to pizzas with diameters of about 23, 30 and 40 cm.
  • Auxiliary request amendments - replacement sheets - 09.05.2016
  • With the object of making the pizza packaging according to the invention stackable, it may advantageously be designed such that the inner support member is constituted by a flat piece of plastic, e.g. polypropylene, which at the top side along its periphery is designed with upright, preferably hollow, upwardly tapering support columns, the pointed ends of which being adapted to engage complementarily designed recesses in the bottom side of the flat plastic piece.
  • It may furthermore be expedient to design the pizza packaging according to the invention such that the support columns and the recesses, respectively, are angularly spaced apart along the periphery of the flat plastic piece such that a number of pizza packagings after turning 90° may be stacked upon each other, as the pointed ends of the support columns in the lower pizza packaging may engage the recesses of an upper pizza packaging with the same design.

    Detailed Description of the Invention
  • The pizza packaging 2 shown in Fig. 1 is designed as a bag packaging including a lower part 4 and an upper part 6 which are both made of plastic film, e.g. polypropylene,
  • Auxiliary request amendments - replacement sheets - 09.05.2016 and which at both side edges 8, 10 and one rear side edge 12 are interconnected by weld seams.
  • At an open front side, the lower part 4 has an extension forming a closure flap 16 which is intended for bending upwards/forwards for fastening to an upper side edge of the upper part 6, as the closure flap 16 for this purpose is provided with a transverse strip 18 of adhesive which in a way known per se is temporarily covered by a tearing strip 20.
  • The upper part 6 on the drawing is shown darker than the lower part 4, indicating that the upper part 6 is provided with an encapsulated metal coating having the purpose of keeping the pizza warm and which does not get in contact with the pizza. The upper part 6 is around a central circular field 22 which in size corresponds to the size of a pizza designed with an annular zone 24 provided with a very large number of micro perforations 26 so that vapour may escape from the hot pizza which thereby does not become soft and spongy.
  • The central circular field 22 of the upper part 6 forms a tearing field 28 which at the front side of the bag packaging 2 has a tearing tab 30. The tearing field including the tearing tab are provided by a an annular series of perforations 32 such that the tearing field 28 can be torn up by gripping the gripping tab 30 and pulling backwards/upwards so that the tearing field 28 - like a lid - is pulled off, providing free access to the pizza.
  • At the lower part 4 is provided a lower square support member 34 which is intended for supporting a pizza disposed inside the pizza bag 2, and which is constituted by a relatively stiff material, e.g. fibre cardboard or plastic. The support member 34 is fastened to the outer side of the lower part 4.
  • The pizza bag 36 shown in Fig. 2 is largely designed as the pizza bag 2, why the same reference numbers are used for the same parts, the difference being that the outer support member 34 has been substituted by an inner disc-shaped support member 38 provided with an annular upwardly/outwardly sloping edge part 40.
  • Irrespective of the support member has been disposed inside or outside the bag packaging 2, it may be advantageous if the support member 34, 38 is made of the same type Auxiliary request amendments - replacement sheets - 09.05.2016 of plastic material as the bag film, e.g. polypropylene, such that it becomes further easy to fix the support member 34, 38 to the lower part 6 by means of a suitable number of weld points.
  • A very important aspect of the invention is to save work time and storage space for preparation and folding of prior art folding boxes of cardboard, so that the subsequent packing of baked pizzas can be made efficient by using quite flat bag packagings which in a way known per se can be stored suspended on a wall in layers of bags, wherefrom the bags can be taken one by one in the situation of use.
  • Figs. 3 and 4 show a preferred embodiment of a support plate 42 for use by a stackable pizza packaging. The support plate 42 which is made of a suitable plastic material, e.g. polypropylene, is U-shaped along the periphery with upright hollow upwardly tapering support columns 44, the height of which adapted to the thickness of a pizza.
  • The pointed ends 46 of the support columns 44 are adapted to interact with recesses 48 made at the bottom side of a corresponding support plate 42, as the mutual angular position of support columns 44 and recesses 48 are adapted such that they also fit together after turning an upper pizza packaging 90°, so that it may be supported on the support columns 44 by a corresponding lower support plate 42 of a corresponding pizza packaging (Fig. 4). For the sake of clarity, the bag-shaped pizza packaging is omitted in Fig. 4.
  • In Fig. 3, the mutual angular displacement is 110° and 70° between two support columns 44 and two recesses 48, respectively. Any other angular displacement may be applied if only their sum is 180°. For example, a mutual angular displacement of 100° and 80°, respectively, between support columns 44 and recesses 48 is also acceptable.
  • In connection with production and distribution, support plates 42 may be stacked in a denser and less space-consuming stack because the support columns 44 are hollow and open downwardly. In practice, the support columns may probably have greater width along the periphery of the support plate 42, but may still be hollow and open downwardly.
