Definitions

  • the application concerns a lid for a container, said lid being formed from a first material layer and a second material layer, said first material layer being thermoformed and said first and second material layers being attached to eachother.
  • Container lids of the above mentioned type are known in the prior art and have found widespread application in the area of dairy products such as butter, margarine ' and cheesespreads for example.
  • Such lids are normally constit ⁇ ted by two material layers, one of said layers having been heated and then shaped or formed (thus thermoformed) into its final shape which normally includes a reclosable flange, and the other layer being a second, flat and printed layer (label layer) of cardboard or of a flexible sticky-back type.
  • label layer a glue application or mechanical attachment means are required such as projections formed on the first layer flange which overlap the edges of the cardboard layer and hence attach one layer to the other.
  • the label normally has pressure-sensitive adhesive and is applied using minimal pressure to the thermoformed first layer.
  • lids of the prior art are however not readily suitable for recycling without additional handling.
  • special means are required for separating the cardboard from the thermoformed first layer when the containers are returned and in the case of the glued label, special means are required to remove the stuck label from the first layer.
  • thermoform a lid of only a single material layer In order to provide a container lid which is readily recyclable, it is known to thermoform a lid of only a single material layer and then subsequently to print directly on to said layer.
  • the printing operation must take place after the lid has been thermoformed (to avoid that the printed matter becomes distorted or ruined due to thermoforming temperatures) a problem arises in that standard offset printing is no longer possible since standard offset high-speed printing techniques in this industry normally print on to a large flat sheet, whereas the small thermoformed lid has a raised flange for attachment to the container. Consequently it requires special design of the offset equipment to adapt it to the limited space available for the printing elements which have to be introduced into the flat area of the lid surrounded by the raised flange.
  • EP-A-0 395 585 for producing a two layer container with a truncated outer label layer.
  • this method of production requires the use of a heat shrinkable film for the outer layer which has to be applied in a first step to a pre-former die whilst in a heated state and then subsequently inserted into a female mould.
  • EP-A-0 249 363 discloses, in one embodiment, a method whereby a label and lid may be combined without intermediate material.
  • this process relates to injection moulding which consequently involves molten material entering the mould cavity.
  • the temperature of the molten material is detrimental to the label layer and thus special measures must be adopted in the form of protective patches applied to the label at the points where plastics material enters the mould.
  • This protective application results in extra process steps of patch fitment with consequent increase in material and time costs.
  • the solution provided by the present invention allows conventional thermforming equipment and conventional o fset printing equipment to be employed and avoids the necessity for any adhesive, binding substance or any mechanically- formed connections between the layers. This is achieved by utilisation of the heat stored in the first material layer when it is heated in order to soften it for thermoforming it into the closing lid final shape.
  • the second layer Prior to forming the heated first layer in the mould, the second layer, already having been printed, is placed with its printed surface lying on the cool female section of the mould of the forming apparatus and its non-printed surface facing the heated first layer above it.
  • the first layer is pressed against the second layer and the heat of the first layer produces a fused connection at the interface of the first layer and the second layer. Since the flat, cooled female section of the mould faces the second layer printed surface, the printing remains intact and undistorted.
  • the same material can thus be used for both the first and the second layers of the lid and, since no binding solution or other binding layer is used between the layers, a perfectly recyclable container consisting of one material only is provided.
  • the lid merely needs to be ground down to provide a new source of material for renewed lid/container production.
  • thermoformable materials already find wide application in current lid manufacturing technology such as PVC, polyethylene, polypropylene or plastic laminates, to name but a few.
  • the lid and method of this invention are clearly not limited to one type of material and any suitable thermoformable material can be used for the first layer as long as it can be bonded to the second material layer merely by the use of heat without binding material of any sort between the surfaces of the layers.
  • the most usual form of the container lid would be where both the materials of the first and second layer are non-laminates. This is even more advantageous where the container case section is also formed of the same material, such that separate recycling processes for the container and lids do not need to be used. Additionally and importantly, the full advantages of standard printing facilities for flat sheet are maintained.
  • Fig.l shows a finished container lid with a closing flange.
  • Fig.2 shows a section through the lid taken along line I-I of figure 1.
  • Fig.3 shows a sectional view through the lid, along line I- I of figure 1, during thermoforming of the lid in the thermoforming mould.
  • Figure 1 shows a container lid of the present invention generally denoted by the reference numeral 1.
  • the container lid consists of two material layers, the first material layer 2 being a thermoformable foil of any suitable material such as PVC, polypropylene or polyethylene for example.
  • the second material layer or label layer 3 of the lid is bonded to the upper surface of the first material layer 2 without the use of any adhesive, hot-melt compound or other additional material.
  • the second material or label layer generally has printing thereon to enable the product to be distinguished. This printing can be of any desired form, suc . as for example a bar code, general product information, a picture of whatever type or any combination of these.
  • the second material layer 3 consists of a thermoplastics material of any suitable type.
  • the layers 2 and 3 are normally bonded together in the flat or substantially flat region of the first layer which is bounded by the upstanding rib 4 of the closing flange (generally denoted as A in Figure 1) .
  • the raised rib 4 is designed to allow a reclosable connection onto a corresponding section of the container top edge and hence some flexibility is provided in its structure to allow it to elastically deform over the corresponding container top edge. Some reinforcement of the inner part of the lid (normally at the corners) next to the rib can be provided if such is desired.
  • Portion 5 of the lid designates a generally lat section of the lid flange formed around the outside of the raised rib 4, which section can seat upon a corresponding section of the container top-edge.
  • Section 5 is continued in a further vertical or slanted section 5' and finishes in a laterally projecting lip section 6 which can, if desired, be formed with a grip-tab 7 for easier opening.
  • Figure 2 shows the container lid in cross section, the label layer 3 being bonded to the lid layer 2 in the central portion, which is generally flat.
  • the thickness of the second material or label layer 3 is of no particular importance but it is normally kept as thin as possible to avoid material waste. As such, the thickness would normally be of the order of 20 ⁇ m but can be as little as lO ⁇ m or as high as 80 ⁇ m or even more if required, whereas the thickness of the first layer is generally greater since this is used to give form-stability to the lid section.
  • An order of thickness in the region of 160 ⁇ m up to 300 ⁇ m is normal, but clearly other higher or lower values can be used as long as sufficient stability is maintained.
  • the second or label layer 3 is attached to the flat area of the first material layer 2.
  • the label layer is generally printed using a standard offset printer to print a large sheet or web of labels. The labels are then cut and punched out of the printed sheets to the required label size.
  • a forming tool which has a female part consisting of mould elements 11 and 12 separated along the line 13.
  • the second material layer 3 being precut is positioned, as shown, on the mould part 11.
  • a vacuum is applied to the drillings 10 in the mould piece 11 such that the precut material layer 3 is held in this position.
  • the foil which constitutes the first material layer 2 is in the form of a continuous web and is roller driven towards the mould and then heated by a source of heat (not shown) positioned generally just outside of the mould.
  • the first material layer 2 is either vacuum formed entirely, or a male member (not shown) of the moulding machine presses the foil (first material layer) into the shape of the female sections 11 and 12 depicted.
  • the application of force to the foil 2 also applies a force down onto the second material layer 3 lying with its printed surface against the mould, the heat and pressure from the first layer 2 being such as to cause the first layer to become molecularly bonded to the second layer 3, without that any material need be placed between the layers (such as hot-melt for example) .
  • the mould is of course cooled such that the heated and formed lid will not adhere to the mould, which obviously allows the added advantage that the printed surface of the second layer can directly contact the mould without resultant damage to the printed matter.
  • the mould is opened along line 13. by a vertical movement of part 12 relative to part 11, the lid ejected, punched and then conveyed for stacking.
  • the lids consist of one layer which is first vacuum-formed and then printed. Since the printer operates at much faster speeds than the thermoforming machinery, several ther oform machines work in parallel to supply a single print machine in order that the economy of rapid production is preserved. However, stacking of the thermoformed lids with flanges is required in order to feed the machine adequately. The required buffer zone of stacked lids, the problems of synchronisation and the reliability of stacking and de- stacking of lids with flanges is considerable, but one which industry has thought unavoidable if a fully recyclable lid with printing is to be produced. However, by the method of the present invention all these problems are avoided, since the flat, precut, preprinted and dried label layers 3 are merely placed in a conventional dispensing apparatus for flat articles and then transferred into the mould cavity, the dispensing and transfer apparatus being conventional equipment.
