Definitions

  • the present invention relates to a container to be used as a package comprising at least one compartment defining an opening for receiving objects to be packed and a surrounding rim, at least the upper side of the container defining an opening being lined with a peelable plastic film as set forth in the preamble of independent claims 1 and 8.
  • a container of this kind is disclosed in DE-4 327 669.
  • containers made on the basis of a usually permeable substrate of inorganic materials such as for example foamed plastic, or organic materials such as moulded pulp, or mixtures of organic and inorganic materials such as starch and chalk are a desirable form of packaging since they can be mass produced in an inexpensive manner and are environmental friendly.
  • a plastic film is laminated to the substrate on at least one side to render the package moist resistant and gas tight so that it can be used to contain wet products such as food or beverages and allow the above mentioned hermetic sealing for preservation purposes.
  • the container cover also called top sheet
  • the top sheet In order to unpack the goods the top sheet has to be torn off from the container. This step leads to problems because the force for tearing off the top sheet tends to also tear the plastic film lining the container off the base material. If this happens, the goods remain in an unstable possibly leaking package like a bag which is formed by the top sheet and the plastic film. This situation is highly undesirable since it will be very difficult to remove the packed goods without spilling.
  • the rim comprises a flange for handling purposes.
  • the plastic film may be bent around the peripheral edge of the rim.
  • the rim may have a peripheral area with an upper surface that is below the upper surface of the inner area of the rim.
  • the bond between the plastic film and the rim can be made substantially stronger than the bond between the film and the container in the other areas of the tray, for example by welding the plastic film to the rim.
  • the container is made of permeable material.
  • the container may be in the form of a tray and may have more than one compartment.
  • the container can also have the shape of a drinking cup or a can.
  • a container 1 according to an embodiment of the invention is shown with reference numeral 1.
  • the container 1 according to this embodiment is a so-called food tray comprising a three-dimensionally contoured body, preferably of a permeable material such as moulded pulp and covered on one side with a plastic film 4. It will be appreciated that materials other than moulded pulp material could be used for the container 1.
  • the container 1 defines a compartment 3 for receiving goods. Such goods may be wet or in liquid form.
  • the compartment 3 defines an opening 2 in the container 1 which is surrounded by a peripheral ring flange 6.
  • the moulded pulp material of the container 1 is laminated on at least one side with a plastic film 4 such as polyester to prevent the contents, normally food stuffs including liquid, of the container 1 permeating the board material.
  • the plastic film 4 material is laminated to the container 1 by hot pressing and the application of a vacuum through the container in a conventional manner. Thus the plastic film 4 is bonded all over to the one side of the container.
  • a suitable material for the film 4 is extruded polyester film, although other materials could be used.
  • the plastic film 4 may be multilayered and also biodegradable films may be used.
  • the film 4 should preferably display gas barrier qualities in order to be able to hermetically seal the goods for preserving reasons.
  • the so-called EVOH film is particularly suitable if gas barrier properties are required.
  • a cover 8 can be sealed to the plastic film 4 around the rim 6 of the container 1 in a conventional manner, once the container 1 has been filled with the required contents. This operation may be carried out by welding or heat sealing.
  • the cover 8 may be provided with an ear 5 for gripping the cover when tearing it off.
  • the plastic film 4 may be provided with an ear (not shown) for peeling the plastic film 4 off the container when recycling.
  • the plastic film 4 is folded over the edge 9 of the rim 6 so that the edge of the plastic film 4 is facing down.
  • the cover 8 is sealed only to the top of the rim 6 and therefore a peripheral zone of the plastic film 4 is not bonded to the cover 8.
  • Such a peripheral zone of the plastic film 4 that is not bonded to the cover 8 can be achieved in other ways which are shown in the embodiments according to Figures 2d to 2f.
  • the rim 6 may, as shown in Figure 2c, be provided with a flange 7 with an upper surface disposed below the upper surface of the rim 6 as shown in Figure 3.
  • the flange 7 is disclosed in the drawings as extending horizontally, it is understood, however, that the flange may extend non-horizontally.
  • Figure 2d discloses a further embodiment of the container 1 in which the rim 6 comprises a thin peripheral section forming a kind of flange 7, thus leading to the upper surface of the thinner section being disposed below the upper surface of the rim 6.
  • the waste material surrounding the rim is removed by die-cutting.
  • the plastic film is partially melted and drawn down with the knife, thus forming a peripheral zone of the plastic film 4 that will not be bonded to the cover 8 (as shown in Figure 2f).
  • Figure 3 shows a multicompartment tray 1, which could be used to be filled with different components of a ready-meal.
  • the rim 6 surrounds the openings of the compartments 3.
  • the rims between adjacent openings 2 are not normally affected by the above-mentioned problem of unintended peeling off of the plastic film 4, but may as described in more detail with reference to Figure 4 be only partially bonded with the cover 8.
  • FIG. 4 Another way of achieving a peripheral zone of the plastic film 4 that is not bonded to the cover 8 is by selectively bonding the cover 8 to the plastic film 4 at the rim 6.
  • the container 1 has a conventionally shaped rim 6.
  • the plastic film 4 ends at-the edge of the rim 6.
  • the cover 8 is, however, not bonded to the total area of the rim 6.
  • a selective hot tool (not shown) only the inner area 10 of the rim 6 is bonded to the cover 8, whereas the peripheral area of the rim 6 is not bonded to the cover 8.
  • Bonding the cover 8 to a selected area 10 of a conventional rim 6 may also be obtained by selectively applying adhesive to the desired area 10.
  • the bond between the plastic film 4 and the rim 6 is substantially stronger than the bond between the plastic film 4 and the rest of the container 1 due to welding (temperature or high frequency) the plastic film 4 to the rim 6.
  • This stronger bond may also be obtained by applying a special adhesive to the rim 6 when laminating the plastic film 4 onto the container 1.
  • plastic film has been addressed as "plastic film".
  • plastic film is meant to comprise any shapable film such as starch based (biodegradable), rubber based, cellulose based and polymer based films, which are suitable for lamination onto a container.
  • the container according to this invention may be made of non-permeable material.
