Definitions

  • This invention relates to a self-venting cover for a heatable food package, and in the preferred embodiment provides cover particularly suitable for a food package intended for microwave heating.
  • Food products particularly pre-cooked food products, are cormnonly sold m packages which are intended for re-heating either in a conventional oven or in a microwave oven.
  • Such packages commonly comprise a relatively rigid tray which contains the food product in question and a film cover which is secured to the tray around the top edge thereof.
  • packages which include vent systems which automatically vent the package in the event of elevated temperature and/or elevated pressure within the pack.
  • vent systems which automatically vent the package in the event of elevated temperature and/or elevated pressure within the pack.
  • Such systems are shown, for example, in EP-A-0174188 and US-A-5989608.
  • the prior art proposals appear to offer solutions to the problem outlined above, they are in themselves deficient in various respects.
  • the automatic venting systems of the prior art may under certain circumstances not be effective to provide the required venting with the result that excessive pressure builds up within the pack, and also suffer from the disadvantage that the venting aperture will be re- sealed in the event that pressure within the pack falls below the pressure on the exterior of the pack. This can result in implosion of the pack.
  • venting of a package to prevent explosion is desirable, that venting should ideally be carried out in a controlled manner, at least during the early phases of heating, so as to derive benefit from a super-ambient steam pressure generated within the package.
  • a self- venting cover for a heatable food package comprising: a sheet of film having at least one opening formed therein to permit the passage of steam therethrough; and a label secured to the film for controlling the flow of steam through the opening, the label comprising a sheet of material having a first region secured to the film in an area remote from the opening and having a second elongated region covering the opening, wherein the elongated region is only partially secured to the fihn and a vent passage is defined between the unsecured portion of the elongated region and the film itself, the vent passage extending from the opening towards the periphery of the label to pe ⁇ nit controlled venting of steam from the opening.
  • the label includes a strip which is non-adhesive and which, in one embodiment, extends the full length of the label, in particular all the way to the opposing edges of the label to provide two vent passages and which, in total, extends the full length of the cover to provide two vent passages from the aperture.
  • a strip which is non-adhesive and which, in one embodiment, extends the full length of the label, in particular all the way to the opposing edges of the label to provide two vent passages and which, in total, extends the full length of the cover to provide two vent passages from the aperture.
  • the non-adhesive portion of the label is surrounded by adhesive, at least one side of which is relatively narrow compared with the adhesive bounding at least one other side of the non-adhesive portion.
  • the passage does not extend all the way to the edge of the label and instead the relatively narrow region of adhesive bordering the non-adhesive portion will lift as pressure within the passage increases to a pre-defined level so as to allow venting to atmosphere.
  • the label includes a relatively narrow region adjacent the aperture and a relatively wide region located spaced from the aperture.
  • the relatively wide region provides a large area for adhesive bonding or welding of the cover to the fihn. By this means, complete detachment of the cover from the fihn is avoided.
  • the relatively narrow region allows the portion of the label which overlies the aperture to become detached from the film during heating, thereby providing a free and unrestrictive passage through the opening in the later stages of package heating.
  • At least the portion of the label which overlies the opening is of a material which tends to shrink when heated.
  • shrinkage assists in detaching the label from the firm in the region of the opening and ensures that the label will not re-close the opening in the event that pressure within the package temporarily falls to a sub- ambient level.
  • the opening is in the form of a slit cut in the material of the film.
  • the slit may be a simple linear slit running in the machine direction of the machine used for forming the cover. Such an arrangement is particularly easy to implement in practice.
  • the opening is in the form of a hole punched in the material of the film. More particularly, the two concentric, circumferentially spcaed circular arcs are cut in the film so as to form two semi-circular flaps which are connected to the film by a pair of common, radial tabs which separate the arcuate cuts. It will, of course, be understood that other hole shapes may be used, such as square, but appropriate shaping of the slits which form the two flaps.
  • the invention may be embodied as a cover which is secured by appropriate means to a relatively rigid tray.
  • the cover is securable to a tray by way of a peelable bond facilitating easy removal of the cover in order to serve the product contained within the tray.
  • the cover may be used in association with other film material to form a package in another form such as a flexible bag or pouch.
  • the material of the label can be relatively thin material, for example 50 microns thick PVC.
  • Such an arrangement is particularly desirable because the covers can be pre-formed in a packaging factory environment and reeled for delivery to a food packaging factory for ultimate use. This is a considerable advantage over relatively complex arrangements using multi-layer materials which are not susceptible to reel delivery.
  • Figure 1 is a top plan view of a food package provided with a cover in accordance with a first embodiment of the present invention.
  • Figure 2 is a top plan view of a label in accordance with a second embodiment of the invention.
  • the package 1 illustrated comprises a cover 2 which is bonded to the upper edge of a tray containing a food product.
  • the cover 2 comprises a sheet of film material 3 and a label 4 secured to the film material by adhesive.
  • the film 3 is formed with a slit 5 running in the machine direction A of the machine which was used to form the cover.
  • the slit 5 may be a through slit or maybe a line of weakness which, when pressure begins to build within the package, will open to provide an opening.
  • the position of the slit 5 is such that it is covered by an elongate portion 6 of the label 4.
  • the label 4 includes, in addition to the elongate portion 6, a generally circular portion 7.
  • the label 4 is secured to the film 3 by two areas of adhesive 8, 9.
  • the areas of adhesive are separated by a central strip 10 which is not adhesively secured to the film. As illustrated, the strip 10 runs the entire length of the label 4 in the machine direction A.
  • the strips 8, 9 and 10 are formed by laying down two spaced apart strips of adhesive on the material of the label 4 before the label is secured to the film. It is to be noted, however, that other arrangements are possible such as other pattern coatings, or in particular if desired the entire surface of the label 4 facing the film may be coated with adhesive, and a central strip of that adhesive may be treated in some way to prevent adhesion to the underlying film 3. Alternatively, it may be possible to secure the label 4 to the film by means other than adhesive, for example a welding process.
  • the film 3 is a polyester/polypropylene laminate comprising a layer of approximately 12 microns of polyester laminated to a layer of 50-70 microns of cast polypropylene.
  • the label is formed from a shrink grade PVC film, for example 50 microns thick and is secured to the firm by a suitable food grade adhesive, for example an acrylic based adhesive.
  • vent passages 11 , 12 are defined between the material of the film 3 and the material of the label 4, the vent passages connecting the opening formed by the slit 5 to the exterior of the package.
  • the material of the label will tend to shrink under the influence of heat. Accordingly, as heating of the package continues the elongate region 6 of the label will tend to detach itself from the underlying film and shrink back towards the round portion 7.
  • the round portion 7 will be less liable to detach from the film 3 because of the larger area of contact of adhesive between the round portion 7 and the film 3.
  • the shrinking of the label material means that after a certain period of heating the label will not be able to re-adhere to the fihn material in the region of the slot and accordingly implosion of the package will be prevented.
  • the relatively large area of adhesive provided in the rounded portion 7 will ensure that the label does not become completely detached from the film 3.
  • label 14 which is of similar size and shape to the label of Figure 1 and is used in conjunction with a packaging cover as described above in connection with Figure 1.
  • label 14 is secured to the film by a single area of adhesive 18 which in particular extends around the entire periphery of an adhesive free region 15 which is formed on the elongated portion 16 of the label 14 and which, when applied to the cover material, overlies a venting aperture in the film so as to form a venting passage.
  • the venting aperture is formed by a paii" of arcuate slits , the ends of which are separated so as to form a pair of substantially semi circular flaps 20a, 20b which remain attached to the film, and through which steam from within the packaging can vent it will, of course, be understood that a linear slit may be used with the embodiment of Figure 2, as may arcuate slits with the embodiment of Figure 1.
  • the relatively narrow width of the adhesive 18a which bounds the adhesive free region 15 on three sides is of lower strength than that of the adhesive 18b provided on the generally circular portion 17 of the label 14, due to the difference in the contact area of the two adhesive regions 18a, 18b.
  • the edge of the label 14 also has an adhesive free region 21 which extends around the entire periphery so as to form a margin around the label which is not bonded to the underlying cover.
  • a margin may also be provided on the label 4 according to Figure 1.
  • the margin is 1 ,5mm wide and the region of adhesive 18a surrounding the adhesive free region 15 is 2 mm wide.
