Definitions

  • the present invention relates to a method of manufacturing a package and to a packaging machine.
  • a method of manufacturing a package in which a container is formed in a web of a first web-like material, subsequently a lid is sealed onto the produced container within an outer contour of the package to be produced, and the container is separated from the first web-like material along the outer contour of the package to be produced and outside the lid that was sealed on.
  • packages which comprise a so-called rolled edge and are usually sealed on a tray sealing machine after they have been filled. That means, already finished trays are filled and subsequently sealed.
  • packages are often provided with a slip lid which is also produced outside the tray sealing machine and which is to ensure that the packages can be reclosed after the sealed foil has been opened.
  • Conventional slip lids however, only have a very loose seat, so that already during the transport of the package, the slid lid often detaches itself from the package. For the consumer, too, the loose seat of the slip lid is disadvantageous and annoying when the package is handled.
  • the object may be achieved by a method according to claim 1 as well as by a packaging machine according to claim 10 . Further developments of the invention are given in the respective sub-claims.
  • packages can be produced which are easily manageable thanks to the stable seat of the slip lids on the containers and comprise an optically attractive shape.
  • the slip lid may be connected to the bottom film, that means to the previously deep-drawn container, by several sealing points or strips, respectively, to prevent the slip lid from detaching itself during transport. These comparatively small seal areas can be easily removed or broken open by the consumer.
  • the knobs according to the invention which are provided at the slip lid as well as at the container, moreover ensure a secure and accurate reclosability of the package.
  • a further advantage of the method according to the invention or the packaging machine, respectively, is that the slip lid is cost-effectively produced and placed on directly by means of the packaging machine. Thus, no further machine that produces and places on the slip lid is required. Moreover, the interface and transfer problems of produced packages and/or lids to other packaging machines that occur in conventional methods are eliminated here.
  • the packages are separated into singles only at the end of the packaging process, and reliable transport is ensured during the packaging process.
  • the packages can be separated from the web-like material accurately and close to a given, individually shaped outer contour, whereby optically attractive and mechanically stable packages can be produced.
  • FIG. 1 shows a schematic side view of a packaging machine
  • FIG. 2 a shows a schematic perspective view of a container produced in accordance with the method according to the invention
  • FIG. 2 b shows a schematic perspective view of the container with a first lid
  • FIG. 2 c shows a schematic perspective view of the container with the first lid and a second lid
  • FIG. 3 a shows a schematic partial view of the edge region of the container and the first and second lids in a first embodiment
  • FIG. 3 b shows a schematic partial view of the edge region of the container and the first and second lids in a second embodiment
  • FIG. 4 shows a schematic plan view of a cutting station.
  • FIG. 1 shows the schematic side view of a packaging machine 100 .
  • the packaging machine 100 comprises a first forming station 1 , a first sealing station 2 , a second forming station 1 ′, a second sealing station 2 ′, a cross cutter 3 and a longitudinal cutter 4 which are in this sequence arranged at a machine frame 5 in a direction of transport R.
  • a first feed roller 6 is disposed at the machine frame 5 from which roller a first web-like material 7 or a first foil is reeled off.
  • a second feed roller 8 is provided from which a second web-like material 9 or a second foil, respectively, is reeled off.
  • a third feed roller 8 ′ is provided from which a third web-like material 9 ′ or a third foil, respectively, is reeled off.
  • a first discharge means 10 in the form of a roller is provided onto which a residual foil skeleton 90 of the second web-like material 9 is reeled which remains after the first sealing station 2 .
  • a first transport means 11 is furthermore provided by which the second web-like material 9 is, in a main cycle, transported into the first sealing station 2 , cut there and the residual foil skeleton 90 is transported out of the first sealing station 2 .
  • a second transport means 11 ′ is provided by which the third web-like material 9 ′ is transported into the second sealing station 2 ′ in a main cycle. Both transport means 11 , 11 ′ can be realized, for example, by laterally arranged chains or grippers or by friction rollers.
  • a second discharge means 12 is provided in the form of a conveying belt at the packaging machine 100 , by means of which finished, separated packages are carried away.
  • the packaging machine 100 comprises a non-depicted feed means which laterally grips the first web-like material 7 and intermittently transports it further into the direction of transport R in the main cycle.
  • the (non-depicted) feed means can be realized e.g. by laterally arranged conveyor chains, lateral grippers or functional rollers.
  • the first forming station 1 and the second forming station 1 ′ are embodied as deep-drawing stations in which containers 13 are formed in the first web-like material 7 in the first forming station 1 by deep-drawing and second lids 14 ′ are formed in the third web-like material 9 ′ in the second forming station 1 ′ by deep-drawing.
  • the edge of the container 13 is here embodied as so-called rolled edge, that means in a shape angled or bent upwards or above the foil plane of the first web-like material 7 . In the present case, the rolled edge is bent outwards and towards the container bottom.
  • the first forming station 1 and the second forming station 1 ′ can be designed such that several containers 13 are formed next to each other in the direction perpendicular to the direction of transport R, that means in FIG. 1 into the plane of projection or out of it, respectively.
  • a non-depicted filling station is provided in which the containers 13 formed in the first web-like material 7 are filled for example with fruit or vegetables.
  • the first sealing station 2 is embodied as combined sealing and lid cutting station.
  • the first sealing station 2 is embodied such that first lids 14 are cut out of the second web-like material 9 and sealed onto a surrounding upper edge of the containers 13 . It is also conceivable to supply already formed and/or cut first lids 14 .
  • the second sealing station 2 ′ is embodied such that second lids 14 ′ are placed onto the containers 13 together with the surrounding third web-like material 9 ′ by an integrated (non-depicted) placing-on station.
  • the first, the second and the third web-like materials 7 , 9 , 9 ′ are each formed by plastic foils.
  • the sealing stations 2 , 2 ′ are furthermore embodied as closed chambers in a known manner in which the atmosphere in the containers 13 is replaced by a replacement gas, such as e.g. CO 2 as inert gas.
  • the cross cutter 3 is embodied as a punching machine which divides the first web-like material 7 between adjacent containers 13 together with the third web-like material 9 ′ in a direction transverse to the direction of transport R.
  • the cross cutter 3 operates such that the first web-like material 7 is not cut across the total web width, but is not cut in two at least in an edge region.
  • a region between the packages in the direction of transport R is not cut in two. This permits a controlled further transport by the (non-depicted) feed means.
  • the longitudinal cutter 4 is, for example, embodied as a cutter arrangement by means of which the first web-like material 7 is cut in two together with the third web-like material 9 ′ between adjacent containers 13 and at the lateral edge of the first web-like material 7 , so that there are separated packages downstream of the longitudinal cutter 4 which are separated from the first web-like material 7 and the third web-like material 9 ′ (also see FIG. 4 ).
  • the cutting means can also be omitted in the first sealing station 2 , so that the first web-like material 7 , the second web-like material 9 , and the third web-like material 9 ′ are simultaneously cut in two in the cross cutter 3 and the longitudinal cutter 4 .
  • complete cutting can also be performed.
  • FIG. 2 a shows the container 13 in a schematic perspective view.
  • the first forming station 1 is embodied such that ribbings can be formed in the walls of the container 13 and beads or a relief in the bottom of the container 13 to increase the stability of the container 13 .
  • the ribbings in this case extend on each of the four side walls of the container 13 from the container bottom to the container edge.
  • the beads are formed by individual quadrangular recesses essentially having the shape of a slice of cake which are formed into the container bottom and as a whole form an oval shape.
  • the upper edge of the container 13 is essentially formed by a surrounding, horizontal first edge section 20 , a following essentially vertical and also surrounding second edge section 21 , and an essentially horizontal, also surrounding third edge section 22 . These three edge sections 20 , 21 , 22 form a rolled edge of the container 13 .
  • first projections 16 or first knobs 16 are formed in the second edge section 21 .
  • FIG. 2 b shows, in addition to the container 13 , the first lid 14 which is sealed onto the containers 13 after they have been filled. It is also conceivable to treat the package or the product, respectively, with gas before it is sealed to increase its shelf life.
  • FIG. 2 c shows the container 13 , the first lid 14 and the second lid 14 ′.
  • the edge of the second lid 14 ′ is formed corresponding to the edge contour of the container 13 .
  • an essentially horizontal first edge section 20 ′ is provided which is followed by an essentially vertical second edge section 21 ′ and which in turn is followed by an essentially horizontal third edge section 22 ′ extending in the plane of the originally web-like material 9 ′ of the second lid 14 ′.
  • Second projections 17 or second knobs 17 are formed into the second edge section 21 ′. It is also conceivable to form a further recess open to the outside into the second lid 14 ′ into which for example a fork or salad dressing can then be placed. These would then be fixed e.g. by sticking on a label.
  • the first knobs 16 and the second knobs 17 cooperate when the second lid 14 ′ is placed onto the container 13 and clamp the second lid 14 ′ onto the container 13 . This ensures a secure and accurate reclosability of the container 13 .
  • FIG. 3 a shows the connection of the slip lid 14 ′ with the container 13 .
  • the first and second knobs 16 , 17 are engaged. Thanks to the plastic material of the container 13 and the second lid 14 ′, the second lid 14 ′ can also be easily removed.
  • the first knobs 16 and the second knobs 17 are directed inwards.
  • FIG. 3 b shows a second embodiment of the present invention.
  • the first knobs 16 and the second knobs 17 are directed outwards. This is realized by a projection of the container 13 and of the second lid 14 ′ extending upwards in FIG. 3 a ).
  • FIG. 4 shows the cross cutter 3 and the longitudinal cutter 4 .
  • the arrow shows the direction of transport R of the packages.
  • the sealing strips by means of which the second lid 14 ′ or the slip lid 14 ′ is partially sealed onto the container 13 are shown (see FIGS. 1-2 c )). Apart from securing the second lid 14 ′ during transport to the end consumer, they also serve as evidence of genuineness.
  • the first web-like material 7 is reeled off from the feed roller 6 and transported into the first forming station 1 by the (non-depicted) feed means.
  • the containers 13 are formed in the first web-like material 7 by deep-drawing.
  • the containers 13 are, as shown in FIGS. 2 a )- c ), formed such that they comprise the horizontal first edge section 20 in their surrounding edge region, which is followed at the outside by the angled or bent second edge section 21 in the circumferential direction, which essentially extends vertically, as is represented in FIGS. 2 a )- c ).
  • the third edge section 22 essentially extending horizontally follows in turn the second vertical edge section 21 . All three edge sections 20 , 21 , 22 are each formed around the complete container 13 .
  • the formed containers 13 are, in a main cycle, transported further to the (non-depicted) filling station together with the surrounding material of the first web-like material 7 , where they are filled with the goods to be packed.
  • the filled containers 13 are, in the main cycle, transported further into the first sealing station 2 together with the material of the first web-like material 7 surrounding them by the (non-depicted) feed means.
  • the second web-like material 9 is, in the main cycle, actively transported into the first sealing station 2 by the transport means 11 .
  • the lids 14 are cut out of the second web-like material 9 with a punching machine and sealed with application of heat between a sealing upper part and a sealing lower part with the material of the containers 13 .
  • the first lids 14 are cut out of the second web-like material 9 such that their outer contour extends within the outer contour of the containers 13 defined by the second edge section 21 and the horizontal section 22 (see FIG.
  • the residual skeleton 90 of the second web-like material 9 remaining after the first lids 14 have been cut out is reeled onto the discharge roller 10 at the exit side of the first sealing station 2 , so that it can be disposed of or recycled, respectively.
  • the now sealed or also filled and gassed containers 13 are transported further into the second 2 ′ sealing means with the (non-depicted) feed means of the first web-like material 7 .
  • the third web-like material 9 ′ is reeled off from the third feed roller 8 ′ and transported into the second forming station 1 ′ by a further (non-depicted) feed means.
  • second lids 14 ′ are formed in the third web-like material 9 ′ by deep-drawing.
  • the second lids 14 ′ are in the process formed in the shape which is shown in FIG. 2 c ), such that their edge sections 20 ′, 21 ′, 22 ′ correspond to the edge sections 20 , 21 , 22 of the container 13 .
  • the formed second lids 14 ′ are, in a main cycle, transported further into the second sealing station 2 ′ together with the surrounding material of the third web-like material 9 ′ by means of the second transport means 11 ′, where they are placed onto the containers 13 by means of the placing-on means. Moreover, the second lids 14 ′ are cut out of the third web-like material 9 ′ with a punching machine before, during or after they are placed on, and partially sealed with the second web-like material 9 between a sealing upper part and a sealing lower part in the form of sealing strips with application of heat (see FIG. 4 ). By this, the slip lid 14 ′ remains secured on the container 13 even during transport. A consumer can easily break open the not continuous sealing strips.
  • the sealed containers 13 provided with the second lids 14 ′ as well as with the surrounding third web-like material 9 ′ are transported further into the cross cutter 3 by the (non-depicted) feed means of the first web-like material 7 , where the first web-like material 7 is cut in two between the containers in the direction perpendicular to the direction of transport R (also see FIG. 4 ).
  • the containers 13 with the first web-like material 7 not yet cut in the direction of transport R are transported further to the longitudinal cutter 4 together with the third web-like material 9 ′.
  • the first web-like material 7 is cut along the outer contour of the containers 13 together with the third web-like material 9 ′ in the direction of transport R, that means in the longitudinal direction.
  • the containers 13 and the second lids 14 ′, respectively, are now completely cut out of the first web-like material 7 and the third web-like material 9 ′ and are carried away as separated packages by means of the third discharge means 12 .
  • the packages shown in FIG. 2 a ) to FIG. 3 a ) can be manufactured.
  • the produced package comprises an optically attractive second edge section 21 angled or rounded towards the bottom.
  • the described packaging machine 100 permits to manufacture optically attractive packages with angled or bent around edges on a deep-drawing machine, where the containers 13 , the first lids 14 as well as the second lids 14 ′ can be fabricated and sealed to each other within a short working path. Furthermore, the control of the containers 13 is not abandoned during the complete process as these are guided along with the first web-like material 7 until the last procedure step. Thus, on a cost-saving deep-drawing machine, packages can be efficiently manufactured with designs that up to now could only be produced with more complex and expensive processes.
  • the transport of the second and the third web-like material 9 , 9 ′ by means of the transport means 11 , 11 ′ has the advantage that the feed of the second and third web-like materials 9 , 9 ′ over the containers 13 can be accurate and the remaining residual foil skeleton 90 can be reliably carried away out of the first sealing station 2 .
  • the cross cutter 3 and the longitudinal cutter 4 can be combined to form one single cutting station where the containers 13 are cut, together with the second lids 14 ′, out of the first web-like material 7 and out of the third web-like material 9 ′, respectively, all around along their outer contours, e.g. with a punching machine.
  • the second web-like material is a so-called skin foil which is not cut in the first sealing station but transported further with the first web-like material. Cutting can also be accomplished outside the package or at the edge of the package.
  • the so-called skin foil is thin and lies against the product to be packed and also against the slip lid or the knobs for reclosing.
  • slip lid is not only adhered to the container by a point seal, but that it is sealed all around to seal the package.
  • the slip lid can be used as reclosable lid.
