Definitions

  • the present invention relates to a packaging comprising an injection moulded container and a lid that can be sealed to the container.
  • a packaging comprising an injection moulded container and a lid that can be sealed to the container.
  • An example of such a packaging is disclosed in SE patent 512 612 and EP patent 2 194 002.
  • the lid is made with a sealing zone for joining directly with the container. Thereby, a solid connection and sealing between the lid and the container may be obtained.
  • a flap on the lid as shown in WO patent application 2009156401 may ensure that the lid is easy to remove from the container.
  • the object of the present invention is to provide a packaging having improved properties by reducing the risk that local defects in the seal may occur, thereby reducing the risk that contaminants may enter the sealed container.
  • the lid of the present invention in an integral manner includes an upper lid portion in the form of a plastic material film that covers a lower lid portion at least along the lid peripheral edge.
  • the plastic material film includes at least along this peripheral edge region a layer of a plastic material which is dimensionally stable at the heat sealing temperature at which the material of the second portion is fused to the container.
  • FIG. 1 is a perspective view of a packaging according to the invention, seen from above,
  • FIGS. 2 a and 2 b are schematic cross-sectional views of a prior art packaging, when the lid is being heat sealed to the container,
  • FIG. 3 is a schematic partial cross-sectional view of the packaging in FIG. 1 .
  • FIGS. 4 a and 4 b are partial schematic cross-sectional views of the exemplary embodiment of the invention, shown when the lid is being heat sealed to the container.
  • FIG. 1 shows a plastic material packaging 1 according to the present invention.
  • the packaging 1 comprises a container 2 and a lid 3 that is heat sealed to the container 1 , numerals 5 and 11 designating a gripping tab for removing the lid 3 and the upper surface of the lid 3 , respectively.
  • the container 2 may have any suitable form, such as round, oval, square or rectangular, and its cross-section may be tapering in downward direction
  • Packagings 1 of this general type are well-known, and may be used for storing various products, such as, for instance, soft dairy products or the like.
  • the container 2 is normally injection moulded and may be provided with a label fused to the outside container side wall through an In-Mould Labelling (IML) process, such as the one disclosed in EP patent 481 090.
  • IML In-Mould Labelling
  • FIGS. 2 a and 2 b where reference numeral 9 indicates a heating/welding bar applied at an elevated temperature T to the lid 3 ′ so as to fuse the lid 3 ′ and container 2 ′ together along a peripheral edge region 4 ′ of the lid 3 ′ along the rim 6 ′ of the container.
  • the plastics material of the lid 3 ′ may locally be displaced away such that no part of the lid 3 ′ is sealed to the rim 6 ′ in spots along the rim 6 ′, as shown in FIG. 2 b .
  • FIGS. 2 a and 2 b show the lid 3 ′ as including a label 10 ′ defining a first portion of the lid 3 ′ and fused to the middle area of a second, lower portion 20 ′ of the lid 3 , such as through the IML-process disclosed in FR patent 2 700 493.
  • the lid 3 is formed as shown in the enlarged view of FIG. 3 where a first portion 10 of the lid 3 provided originally in the form of a film is integral with and covers a second, lower portion 20 of the lid 3 , at least along the peripheral edge region 4 where the lower portion 20 of the lid 3 is fused to the container 2 rim 6 .
  • the first portion 10 of the lid includes at least in and along the peripheral edge region 4 a dimensionally stable layer 12 of a plastic material which is selected such that this layer remains dimensionally stable at the heat sealing temperature T of the heating/welding bar 9 .
  • the temperature T of the heating/welding bar 9 is selected to be between the melting temperature T 1 of the plastic material of the second portion 20 and the melting point T 2 of the layer 12 .
  • the material of the second portion 20 may be PP (Polypropylene) which has a melting point T 1 of about 166° C.
  • the dimensionally stable layer 12 may be of PET (polyethylene terephthalate) which has a melting point T 2 higher than 250° C.
  • the temperature T of the heating/welding bar 9 may be selected to be around 200° C.
  • the layer 12 When selecting the temperature T as described above the layer 12 will remain dimensionally stable during the heat sealing and thus define a stable base or backing for the material of the second portion 20 in the aforementioned edge region 4 . It has been found that this prevents or reduces the risk that the material of the second portion 20 is displaced away. This effect is illustrated in FIG. 4 b ; the plastic material 30 of the second portion 20 along the peripheral edge 4 is heated to its melting point such that the lid 3 is fused to the rim 6 of the container 2 . With the dimensionally stable layer 12 remaining as a backing for the material 30 to adhere to the risk that the plastic material 30 is displaced away is significantly reduced.
  • the second portion 20 of the lid may either define the lower surface of the lid, or the second portion may be an annular or grid-like structure as shown in FIG. 5 of FR patent 2 700 493 whereby the first portion defines the lower surface of the lid 3 .
  • the first portion 10 of the lid may additionally include a barrier layer 14 for controlling the air permeability of the lid 3 and preferably being made of a material selected from the group of SiOx and PVDc.
  • the dimensionally stable layer 12 may conveniently be a polyamide or PET-layer which fulfills the selection criteria when the second portion 20 plastics material is polypropylene PP.
  • the first portion 10 may include a layer 16 , such as a polypropylene layer, of a material similar or identical to that of the second portion 20 and which is fused to the second portion 20 when manufacturing the lid, such as in an IML-process, where the first portion 10 is inserted into the injection mould following which plastics material is injected, thus moulding the second portion 20 and forming the integral connection between the first and second portions.
  • the second portion 20 is made of polypropylene, optionally a polypropylene material containing additives for controlling the strength of the heal seal, as discussed in WO patent application 2007 071252.
  • the lid 3 may include along the peripheral edge region 4 a recess 16 for receiving the welding tool 9 ; to define this recess the second portion 20 may have a reduced thickness along the peripheral region 4 .
  • the film-like first portion 10 shown in the enlarged view of FIG. 3 may be provided as a continuous web which is cut into the desired shape and inserted into the mould in an IML-process.
