Definitions

  • the present invention relates to a skin packaging with a tear-open corner and a method and a sealing station for producing such a skin packaging.
  • Vacuum packaging i.e. packaging from which the air is largely sucked out, is often used to pack food products in order to extend their shelf life.
  • a further development is the so-called skin packaging, in which an elastic top film, the skin film, is placed tension-free and tightly over a base and a product placed on it.
  • the base can also be designed in the form of a bowl in which the product is inserted. After the packaging process, the sealing in a circumferential sealing area, the base and the top film are connected to one another in a gas-tight manner.
  • the skin packaging has properties that allow a particularly advantageous product presentation. This fixes the product in the bowl and prevents the product from falling apart or leaking liquid from the product into the bowl space.
  • the product Due to the stable connection of the underlay and the top film in the sealing area, the product is securely fixed during transport and an unwanted, independent opening of the skin packaging is prevented.
  • the firm connection of the base and top film also makes it difficult for a consumer to open the packaging in order to remove the product.
  • the object of the present invention is to provide an improved opening possibility for skin packaging.
  • the object is achieved by a skin packaging with the features of claim 1, a method for producing a skin packaging according to claim 6 and a sealing station for producing a skin packaging according to claim 10.
  • a skin packaging according to the invention comprises a base and a top film, the top film being a skin film and the base and the top film being sealed together gas-tight along a circumferential sealing area.
  • the base and the top film extend in one or more edge areas outside the sealing area, in particular in the form of a tear-open corner, and are not sealed to one another there.
  • the sealing area extend to the very edge of the skin packaging, so to the cutting edge, it would be difficult for the consumer to detach the top film from the base in a small section, to grasp the top film and to pull it off the base to open the packaging.
  • the top film and the backing are only loosely laid on top of one another in an edge section next to the sealing area, the consumer can easily grasp the top film and pull it off the backing. He therefore does not have to use any additional tools.
  • the sealing area comprises a sealing seam.
  • the sealing seam is also a circumferential, usually relatively narrow and running in the edge area.
  • the top film and the base are connected to one another in a particularly stable manner using pressure and heat.
  • the sealing seam is therefore even stronger than the rest of the sealing area, which reliably prevents the skin packaging from being opened unintentionally, even if particularly heavy or large products are packed or the packaging is subjected to particularly high mechanical loads during transport and sale.
  • the base has an offset in the edge region, which spans the upper film in order to facilitate gripping the upper film and thus opening the skin packaging by pulling off the upper film.
  • the offset which can be in the form of a downward step or bevel, for example, allows the upper film to be gripped directly without having to first spread it out by bending the packaging edge or pressing against the base.
  • the offset can also be shaped as an upwardly directed knob or web, so that the top film is pressed upwards in the unsealed edge area and protrudes. All variants make it particularly easy to open the skin packaging.
  • the base is preferably designed as a shell, in particular as a deep-drawn bottom film.
  • a tray offers advantages when inserting the product, for example prevents liquids from running off, and also offers additional protection of the product through the side edges when the package is closed. This also results in a higher torsional stiffness than with flat underlays.
  • the sealing area adjacent to the tear-open corner has a discrete bend. If the top film is pulled from the tear-open corner towards the bend or towards a corner of the sealing area, the force is concentrated at one point at the corner or bend, and is then distributed evenly over the two sides of the bend. This is how the top film can be peel off particularly well, especially if the top film and the backing are connected by a sealed seam.
  • the upper part of the sealing tool and / or the lower part of the sealing tool is mounted such that it can be adjusted in height in order to be brought closer to one another and to make contact with its first and second frames and thus form a gas-tight sealing tool chamber.
  • the sealing station is further configured to gas-tightly connect a base with an upper film, which is a skin film, by forming a sealing area.
  • the first frame of the upper sealing tool part and the second frame of the lower sealing tool part are configured to clamp a section of the base and a section of the upper film, so that these are excluded from heating and deformation during the sealing process.
  • the required pressures and temperatures can be created within the sealing tool chamber, which are necessary for the sealing process, i.e. the connection of the top film to the base.
  • the clamped sections of the top film and the backing are not influenced thereby, which prevents the formation of a sealing area, that is to say a connection between the top film and the backing, there.
  • the sections can also extend further outward and protrude beyond the frame, so that there is also no sealing process.
  • the sealing station preferably has a height-adjustable sealing plate, the sealing plate having a sealing surface which is suitable for connecting a base to an upper film in a gas-tight manner by forming a sealing seam.
  • the movable sealing plate presses the sealing surface onto the top film and the base, these being mounted on a support surface so that the desired contact pressure can be applied. This creates a particularly stable connection between the top film and the base.
  • the sealing surface can be heated in order to additionally support the formation of the sealing seam.
  • the first frame of the upper sealing tool part and the second frame of the lower sealing tool part are formed from a material approved for the food sector.
  • the frame could be made of stainless steel and the dome and sealing plate made of aluminum.
  • the first frame of the upper sealing tool part and / or the second frame of the lower sealing tool part is formed at least in sections from a plastic and / or ceramic material.
  • the sections that clamp the top film can have a particularly low thermal conductivity, as a result of which no heat is transferred to the top film.
  • the area of the tear-open corner in particular, it makes sense to use such materials so that, for example, heat from the heated dome or sealing surface is not transferred to the top film and the base.
  • the first frame of the sealing tool upper part and / or the second frame of the sealing tool lower part is cooled, in particular water-cooled by channels running therein.
  • an undesired heat transferred into the frame can be dissipated. This is not only helpful for the formation of the unsealed opening aid or tear-open corner, but also offers protection for an operator of the sealing station or packaging machine against heat-related injuries when touching the frame.
  • the frame of the lower part of the sealing tool preferably has a recess which is designed to accommodate a downwardly projecting offset of the base, in order not to deform the offset when the base and the top film are clamped between the two frames.
  • the frame of the upper part of the sealing tool can also have a recess in order to accommodate an offset projecting upwards from the flat base surface of the lower film. The offset, which creates a distance between the base and the top film in order to be able to grip the latter better, is therefore inserted into the recess and thereby also retains its shape and thus its function when the frames are pressed together.
  • the lower part of the sealing tool is at least partially interchangeable to accommodate documents of different shapes, in particular documents in the form of a shell.
  • the same sealing station can seal different packaging as required.
  • One way of realizing this is to use corresponding inserts which are inserted into the lower part of the sealing tool. The documents can then be placed in or on these inserts.
  • Figure 1A shows a sectional view of a skin packaging 1 with an essentially flat base 3, on which a product 5 is placed and sealed with an upper film 7, which is a skin film.
  • the base 3 and the top film 7 are sealed together gas-tight.
  • an unsealed edge area 11 is formed, on which the base 3 and the top film 7 are not sealed together.
  • an optional offset 13 in the form of a step is formed in the base 3, so that the base 3 and the top film 7 are at a distance from one another and the top film 7 can thus be gripped more easily in order to pull it off the base 3 to open the skin packaging 1.
  • Figure 1B corresponds to skin packaging 1, as in Figure 1A shown, but the offset 13 is formed in the form of a slope.
  • Figure 1C shows a further variant of the skin packaging 1, in which the offset 13 is designed as an upstanding knob.
  • the knob may be tapered.
  • the knob can also be a substantially round and / or hollow, point-shaped section of the base 3 which is pushed upwards. However, it can also be a web with a certain longitudinal extent in the base 3 in the unsealed edge region 11.
  • Figure 2 shows a sectional view of a skin packaging 1 with a base 3 in the form of a shell.
  • the skin film 7 encompasses the product 5 inserted into the shell 3, fixes it and rests against the inside of the shell 3 without play.
  • the shell 3 has a raised circumferential and horizontal edge 15, on which the top film 7 forms a circumferential sealing region 9 with the base 3 and sectionally unsealed edge regions 11 are connected.
  • One or more offsets 13 can also optionally be formed in the unsealed edge regions 11.
  • Figure 3 shows a perspective side view of a sealing station 17, comprising a sealing tool upper part 19 and a sealing tool lower part 21.
  • the sealing tool upper part 19 comprises a first frame 23 and the sealing tool lower part 21 the second frame 25.
  • the frames 23, 25 are designed such that they can seal four skin packs 1 per work cycle.
  • the four documents 3, usually connected to one another, here in the form of trays, are placed in the second frame 25.
  • Document receptacles 27 for the shells 3 themselves and recesses 29 for the offsets 13 are formed in the second frame 25.
  • the unsealed edge regions 11 in the form of tear-open corners are expediently oriented toward the edges parallel to the transport direction T, that is to say, for example, towards the transport chains leading to the upper film 7.
  • the circumferential sealing area 9 and the unsealed edge area 11 in the form of a tear-open corner are identified on the basis of the base 3.
  • the sealing area 9 has a discrete bend 31, which improves the opening behavior when the top film 7 is pulled off.
  • 25 holes 33 are arranged laterally in the second, lower frame and serve to evacuate the skin packaging 1.
  • Figure 4 shows the sealing tool upper part 19 from below.
  • Four concave domes 35 are arranged within the first frame 23.
  • the space between the dome 35 and the top film 7 can be evacuated via air channels 37 in the domes 35, so that the top film 7 lies against the respective dome 35 and can be heated by the latter.
  • the first frame 23 has the appropriate shape to match Figure 3 in the area within the first and second frames 23, 25 to create the sealing area 9 and adjacent to it the unsealed edge area 11 of the skin packaging 1.
  • recesses 39 are formed in the first frame 23 in order to enable the region between the upper film 7 and the base 3, ie the interior of the skin packaging 1, to be evacuated by means of the bores 33.
  • Figure 5 shows a perspective sectional view obliquely from below onto a sealing tool upper part 19.
  • the first frame 23 has the shape which defines the sealing area 9 and the unsealed area 11 of the skin packaging 1 (see Figure 3 ).
  • the two domes 35 are formed as part of a sealing plate 41.
  • the sealing plate 41 is arranged such that it can move relative to the first frame 23. In this way, the sealing plate 41 can be moved downwards when the sealing tool chamber is already closed and a sealing surface 43 can be pressed onto the top film 7 and the base 3 in order to connect them in a particularly stable manner.
  • An edge support of the sealing tool lower part 21, on which the corresponding sections of the upper film 7 and the base 3 rest, generates the necessary counter pressure.
  • the cutouts 39 allow the skin packaging 1 to be evacuated by means of the bores 33 arranged in the second frame 25.
  • Figure 6 shows a side sectional view of a sealing station 17 for a skin packaging 1.
  • the base 3 is mounted in the second, lower frame 25.
  • the first frame 23 is lowered onto the second frame 25, a part of the base 3 and the upper film 7 being clamped in between, and a gas-tight sealing tool chamber 45 is thus formed.
  • An optional sealing plate 41 is shown within the first frame 23, which is in an upper position and is displaceable in order to press a sealing surface 43 of the sealing plate 41 downward in order to form a sealing seam 44.
  • An edge support 47 serves as a counter element for the formation of the desired pressure.
  • the upper film 7 is still aligned, an inner section 49 of the upper film 7 and an inner section 50 of the base 3 being inside, and outer sections 51 of the upper film 7 and outer sections 52 of the base 3 are outside the closed sealing tool chamber 45. Parts of the outer portions 51, 52 are between the first and second Frame 23, 25 clamped. Water can be passed through channels 53 within the frames 23, 25 to cool the frames 23, 25.
  • the mode of operation of the sealing station 17 for producing a skin packaging 1 is described in more detail below with reference to the figures.
  • the base 3 is provided in a lower sealing tool part 21 with a product 5 placed on the base 3 and then an upper film 7, which is a skin film, is fed in above the product 5 and the base 3.
  • the sealing tool chamber 45 is closed by pressing together the first frame 23 of the sealing tool upper part 19 and the second frame 25 of the sealing tool lower part 21, the upper film 7 and the base 3 being clamped circumferentially between the first and second frames 23, 25 and the sealing tool chamber 45 by the Pressing together gas-tight is completed.
  • inner sections 49, 50 of top film 7 and base 3 are located within the sealing tool chamber 45 and outer sections 51, 52 outside the sealing tool chamber 45.
  • the inner section 49 of the upper film 7 is now sucked into the dome 35 of the sealing tool upper part 19 by forming a vacuum in the area between the dome 35 and the upper film 7. There, the inner section 49 of the top film is heated.
  • the sealing tool chamber 45 When the sealing tool chamber 45 is closed, the upper film 7 with the base 3 is clamped in the edge area 11 of the skin packaging 1 outside a sealing area 9 between the first frame 23 of the upper sealing tool part 19 and the second frame 25 of the lower sealing tool part 21, so that this edge area 11 of the upper film 7 and the base 3 is neither deformed nor warmed by a pressure difference and so there is no sealing of the upper film 7 with the base 3 in this edge region 11.
  • a vacuum is then formed in the space between the top film 7 and the base 3.
  • the upper film 7 lies on the base 3 and the product 5 located thereon.
  • the base 3 is provided in the form of a bowl with a product 5 placed in the bowl.
  • a sealing plate 41 is pressed onto an edge support 47 of the lower sealing tool part 21 and the top film 7 and base 3 located thereon, and a sealing seam 44 is thus formed.
  • Air is usually evacuated and supplied above the upper film 7 via air channels 37 in the dome 35 of the upper sealing tool part 19.
  • the sealing station 17 can be configured to seal more than two rows of skin packs 1 at the same time.
  • flat supports 3 can also have a corrugation or other embossing, which increases the rigidity of the support 3.
  • the offset 13 can also have any other shape which is suitable for spacing the base 3 from the top film 7.
