Definitions

  • the present invention relates generally to the packaging field and, more particularly, to packaging made of paper or the like, which can be completely gas-tight and liquid-impermeable, and which is primarily, but not only, intended for the reception of food.
  • the packaging is used to store the contents and to transport them to their destination in a perfect state of preservation and presentation. For this reason, the packaging must have a certain stiffness and resistance, so that not only the content but also its wrapping arrive at their destination as unscathed as possible. It is also known that plastics already play an important role in the packaging field and have become practically irreplaceable because of their competitive prices. In fact, the majority of packaging for foodstuffs is now made of plastic, which has all the necessary resistance properties: it can be pressed in a wide variety of shapes and, in addition to its light weight, it is also particularly inexpensive.
  • plastic packaging Another disadvantage of plastic packaging is that no trademarks, legal inscriptions, shelf life information, etc. can be printed unless with the help of sticky notes or printing slips, the latter either being attached to the plastic or inserted into the package.
  • paper containers have already been produced in which a tubular laminated film or the like is attached, which is closed after the goods have been placed in the container.
  • these containers although they have the advantage of being made of cardboard and laminated film, such as aluminum / paper, still have disadvantages because they cannot be filled horizontally and the filling cannot be ordered Arrangement of the goods can be made to present the content in a good presentation.
  • paper containers which have a coating of spray plastic with which the inner surfaces of the container walls are coated.
  • the coating applied to the container is firmly attached to it and cannot be removed or removed.
  • the main object of the invention is therefore to provide a packaging which is particularly but not exclusively intended for solid and liquid foodstuffs, which consists mainly of paper and which can also be hermetically sealed against gas (and the plastic used, if possible, is of a recyclable nature).
  • Another object of the invention is to provide a packaging for foodstuffs predominantly made of paper or the like, in which the goods can be accommodated in an orderly manner in particular and maintain this arrangement.
  • Another object of the invention is to provide a package of the aforementioned type which can hold solid goods containing liquid without impairing the presentation of the contents.
  • Another object of the invention is to provide a packaging of the aforementioned type in which two or more different types of goods can be packed in one and the same container.
  • Another object of the invention is to provide packaging of the aforementioned type in which the food product can be removed and remains in its casing so that pre-cooked food can be packaged, which are to be heated in the oven, in hot water, etc.
  • the lining is removably attached to the outer casing.
  • the lining is permanently attached to the outer casing so that the packaging can absorb toxic substances or the like in this way.
  • the lining is only partially inserted into the outer casing in order to form a gap between the lining and the container bottom.
  • the lining can have a perforated central area.
  • FIG. 1 a packaging according to the invention is shown there, in this case only illustrated, for example, in the form of a shell made of plastic or paper or the like, which can have any geometrical shape or size.
  • the shell essentially consists of an outer shell, generally designated I, a lining, generally designated F, and a cover, generally designated C.
  • the lining F is inserted into the outer casing I, as will be explained below and attached to it either in a permanent manner by welding or gluing or in a detachable manner, for example by spot welding or gluing, so that it adheres to the inner surfaces of the shell walls.
  • the cover C is only welded to the lining F in a sealing manner. In this way, the goods contained therein are in a kind of bag sealed against liquids and gas, which is why the goods packed therein are completely protected and insulated from the outside.
  • the packaging according to the invention is primarily, but not exclusively, intended for foods which are housed in a hermetically sealed bag in this way and can be stored for a long time and even persistently if an inert gas is introduced into the bag, which, thanks to the seal, keeps food inside. Furthermore, given the density of the bag, the tray obtained in this way can also hold goods in a liquid state.
  • the outer casing I is preferably made of paper, preferably cardboard, but could also be made of wood pulp, plastic, aluminum, wood and the like. You must have the resilience that is necessary for the storage of the goods contained while keeping their presentation. If the outer shell is made of plastic, it is correspondingly resistant Use plastic material. If the outer casing is made of cardboard or the like, the usual measures can be taken to make the packaging walls very strong.
  • the lining F can also be a plastic film, as is used today in food packaging and which has the property of being heat-weldable.
  • the cover C also preferably consists of laminated foils or a film, which have the property of weldability. However, this does not exclude that it can also be made from a rigid material, for example cardboard or other. In this case the rigid cover must be made weldable to be compatible with the lining F.
  • FIGS. 3A, 3B and 3C The phases for maintaining the finished packaging are illustrated in FIGS. 3A, 3B and 3C.
  • FIG. 3A shows the shell-shaped outer shell I, which, however, can also take on a different shape without leaving the scope of the invention.
  • FIG. 3B shows the insertion of lining F into the outer casing I.
  • wrinkles form at the corners of the outer casing I, which must be flattened or otherwise removed in order to get the edge of the outer casing I thus lined essentially flat .
  • the lining can be welded in a permanent manner or in a removable manner by spot welding or gluing, as with G indicated to be attached.
  • FIG. 3C shows the finished shell, specifically with the outer casing I, which contains the lining F attached to it, and with the cover C, which is attached after the introduction of the goods to be packaged and by welding onto the lining F, and not onto the outer casing I, is attached as shown in S.
  • the bag formed from the liner F and the cover C, provided that the liner has been removably attached to the outer case I, can be seen to be removed from the outer case I and, for example, in a refrigerator for storage, or if the bag is a pre-cooked product contains, immersed in hot water or placed in an oven to cook the food.
  • the lining F can be permanently attached to the outer shell by welding or gluing and can be fastened to it in this way. This is done when toxic substances are to be packed in the shell, which is why it is important that the bag always remains attached to the outer casing.
  • the liner F is removably attached to the outer shell I, for example by spot welding or gluing, as illustrated in G, the purpose of which is explained below.
  • Figures 4A, 4B and 4C schematically show a practical way of maintaining the packaging according to the invention.
  • the outer casing I is supported with its edges B in a die M.
  • the lining F is spread onto the outer casing I inserted into the die M.
  • a stamp P with a heat sealing device Q is arranged above the die M.
  • the punch P is lowered onto the die M, as a result of which the lining F adheres to the inner surfaces of the outer casing I.
  • Figure 4B If the chuck F is guided into the outer casing I and fastened therein by welding in a permanent manner or by spot gluing or welding G in a removable manner, the stamp P is raised and the shell is filled with the goods to be packaged. After filling, the cover C closing the tray is attached and the heat sealing device Q, as indicated in S, is lowered onto the lining F, as can be seen in FIG. 4C.
  • FIG. 5 shows in perspective another packaging option that can be obtained with the tray according to the invention.
  • the central area A of the lining F is perforated and this perforated part forms the bottom of the lining after it has been attached to the outer casing.
  • the lining is only partially inserted into the outer casing I, so that an intermediate space D is created between the perforated bottom A and the bottom of the outer casing I, which is invisible.
  • This packaging is particularly suitable for liquid-containing solid products, for example fresh meat, cream cheese, etc.
  • the fresh products are indeed supported by the perforated base A of the feed F and the liquid emerging from these products flows through the holes in the base A of the feed F in the space D and remains out of sight.
  • This bowl offers the great advantage of always presenting the goods in a clean manner and thus a pleasant presentation.
  • the lining F is attached to the outer casing by spot welding or gluing F. And once the cover C is welded to the lining F, the meat or cheese-containing bag thus formed can be removed from the outer casing I and placed in a refrigerator for storage, while the outer casing I, which contains the meat or meat the dripping liquid has accumulated, is thrown away.
  • Figure 6 illustrates another feature that the packaging of the invention provides.
  • two lining inserts F1 and F2 are inserted into the outer casing, which is why the shell formed in this way has three compartments L1, L2, L3.
  • the shell formed in this way has three compartments L1, L2, L3.
  • different types of goods can be accommodated, which together form a confection of a food product to be prepared at the moment, for example a pizza or the like.
  • the dough for the pizza could be placed in compartment L3, the fresh ones in compartment L2 Put the tomatoes and the mozzarella or the like in the compartment L1.
  • the two lining inserts F1 and F2 are welded together with the cover C, as a result of which a double compartment bag which can be removed from the outer casing I would result.
  • the cover C can be welded to the chuck F using any technique used today, such as hot welding, ultrasonic welding, high frequency welding, etc., and using materials compatible with these types of welding.
  • the packaging according to the invention also enables the packaging of goods in a completely automatic manner by using a form-forming station for the outer casings, followed by a station for attaching the lining insert, as shown schematically for example in FIGS. 4A and 4B, then a filling station for the goods to be packaged and finally, a welding station for welding the cover, such as the one shown schematically in FIG. 4C, provides.
  • packaging according to the invention all today in Commercially available packaging forms can include, because the inventive concept is expressed in providing an outer casing or a container with a lining and welding the cover element only to the lining and not to the outer casing.
