Definitions

  • This invention relates to improved packaging for perishable goods and relates particularly but not exclusively to improved packaging for meats such as red meats.
  • the packaging is considered to be unnecessarily expensive because of the requirement to provide for multi-layered webs of plastics material for the base and for the lid and for the skin wrapping membrane. Multi-layered webs are required in order to provide for the required gas permeability and/or non-permeability whilst at the same time allowing sealing of the various packaging components together.
  • the machines used for producing the above packaging are considered unnecessarily expensive because, as an example, complicated drive arrangements are required to advance all the webs of plastic material at a controlled rate so that one or more webs will not rupture prior to sealing of the package.
  • the skin wrapping material is used to physically support and hold the goods relative to the base so they do not flop around within the package.
  • the strand means may comprise individual filaments which extend across the upper surface of the goods or may comprise a mesh which is held over the top of the goods.
  • the strand means may comprise a web of plastics material which has been slit and stretched so that it represents an expanded mesh arrangement where the remaining portions of the web material between the slits form strand means.
  • the strand means are of a size which will permit easy viewing of the upper surface of the packaged goods without obstructing direct viewing of a major portion of the upper surface of the goods.
  • the strand means also does not significantly interfere with the gas contacting the surface of the packaged goods.
  • the strand means is such that it is stronger than the skin wrapping webs and hence complicated feeding means for permitting the strand means to be correctly placed within the packaging as needed for the skin wrapping webs is not required. This contrasts significantly with the feed means in packaging machines used for the packaging in the aforementioned patent specifications, where the stretch skin wrapping web has to be controlled precisely thereby so that it will not rupture or buckle or fold.
  • packaging for perishable goods comprising: a base over which the goods are placed; means over the goods holding the goods relative to the packaging; a lid positioned over the top of the base and sealed to the base; a space above the goods and under the lid; a gas in the space, the gas selected for enhancing preservation of the packaging goods by contacting the surface of the goods, and characterised by: the means being strand means and not substantially inhibiting the gas from contacting the goods and permitting viewing of a major portion of the upper surface of the goods.
  • the invention also includes a method of packaging perishable goods to achieve such a packaging.
  • the strand means will hold the goods relative to the packaging such as the base, and if the packaging base and lid are of a clear plastics material, then substantially the whole of the surface of the packaged goods can be inspected by an intending purchaser. Thus, the packaging will be pleasing to an intending purchaser.
  • the packaging comprises a base 1 and a lid 3.
  • each of the base 1 and lid 3 are of shallow tray-like configurations.
  • the lid and the base are both made from PVC which may have a polyethylene coating on the inside faces.
  • the PVC is therefore a substantially gas impervious gas barrier material.
  • the polyethylene coating may be treated with an anti-fogging agent or material.
  • the lid has the PVC of 200um thickness and the polyethylene coating of 80um thickness. Typical size ranges for the lid materials could be for the PVC, 100 to 400um thickness and for the polyethylene coating, 20 to 200um thickness.
  • the base 1 has the PVC of about 400um with a polyethylene coating of about 80um thickness. Typical ranges for the PVC in the base 1 are 200um to 800um and for the polyethylene coating 50um to 100um. Thicknesses outside these limits are possible but the above appears to represent desirable thickness ranges.
  • the base 1 is shaped and sized to neatly receive goods 5 such as red meat therein.
  • Figure 2 shows the arrangement in end cross-section. It also shows that the base 1 has a plurality of upstanding ribs 9 which space the bottom of the goods 5 above the bottom of the base 1.
  • the packaging described above has the base 1 and the lid 3 of a material which substantially inhibits against the gas within the package from escaping and also substantially inhibits other gases from entering the packaging.
  • the polyethylene coating on the inner faces of the base 1 and the lid 3 provides a convenient means to effect heat sealing of the lid 3 relative to the base 5 and to hold the strand means 7 sealingly retained relative to the packaging.
  • FIG. 5 there is shown a particularly preferred embodiment of packaging machine for producing the packaging shown in the embodiments of Figure 1 through 3 with the strand means described therefor or as depicted in Figure 4.
  • the apparatus comprises a pair of spaced conveyor chains 15 which pass over driven sprocket wheels 17.
  • Each of the chains 15 supports a respective side of a plurality of plate means 19 which are pivotally supported relative to the chains 15 by brackets means 21 and pins 23.
  • brackets means 21 and pins 23 This is more clearly shown in Figure 6.
  • Each of the plate means 19 is mounted relative to the chains 15 so that the plate means 19 are almost in abutting end-to-end relationship as shown.
  • the sprocket wheels 17 are indexed in their angular rotation so that the plate means 19 index to various work stations along the apparatus.
  • the plate means 19 index to a second work station 29 where goods 5 are loaded into the trays 1.
  • the plate means 19 then next index to a third work station 31 where lids 3 are placed over the top of the goods 5 in the trays 1.
  • the lids 3 are stacked in a holding column 32 in upside down relationship relative to the base 1.
  • An arm 34 carrying pneumatically operated suction cups 36 swings about pivot 38 so the cups 36 engage with the lowermost lid 3 in the column 32. Suction is applied so the lowermost lid 3 is then held by the suction cups 36.
  • the arm then swings to the position shown in dotted line inverting the lids 3, and suction is released.
  • Figure 6 shows how there are a plurality of upstanding pins 33 on the upper surface of the plate means 19.
  • the pins 33 are spring biased to extend upwardly as shown.
  • Each of the pins 33 around each of the respective apertures 27 aligns the lids 3 relative to the bases 1 carried by the plate means 19 as the lids 3 fall from the suction cups 36.
  • the impulse heat sealing means 51 is provided on the undersurface of the upper platen 37.
  • the impulse heat sealing means 51 may conveniently comprise a known electrical heating strip of flat stainless steel held to the undersurface of the platen 37. An electric current can be supplied to the strip to cause it to heat to, in turn, cause heating of the plastics material around the lip 11 of the base and the corresponding portion of the lip on the lid 3. It will also cause heating of the strand means 7.
  • the lid 3 will be forced towards the base 1 around the lip portions at least and will then cause sealing of the lid 3 to the base 1 with the strand means 7 stretched across the goods 5 and held relative to the packaging.
  • the strand means 7 may comprise individual filaments as shown in the embodiment of Figures 1 through 3 or it may comprise mesh as shown in Figure 4.
  • the sealed packages then index from the fourth work station to a fifth work station 53 where a pair of guillotines 55 will sever the strand means 7 which interconnects each of the packages passing from the fourth work station 35.
  • a pair of guillotines 55 will sever the strand means 7 which interconnects each of the packages passing from the fourth work station 35.
  • the roll of strand means 7 is controlled so that a required tension is imparted to the strand means 7.
  • a guide roller 54 applies to the strand means 7 directly over the top of the goods 5 at work station 31.
  • the first work station 25 may be replaced by a sheet extruder which extrudes the desired plastic material to a thermoforming station which directly feeds bases 1 in continuous strip-like form into the relevant apertures 27 in the plate means 19.
  • a further extruder and thermoformer may be used to provide lids 3 at the third work station 31.
  • the embodiment shown herein represents a very economical machine or apparatus for producing packaging according to the present invention. By using the extruders and thermoformers as suggested above, more sophisticated apparatus can be developed to assist throughput. All this is considered within the skills of the packaging arts and therefore has not been disclosed in detail herein.
  • FIG. 7a and 7b there is shown a web of plastics material 57 which is used to provide the strand means 7.
  • the web is of the required thickness and of the required material. It is first slitted in a series of rows as shown by numerals 59. The web 57 is then elongated both longitudinally and transversally or in only one direction if required, so that the web 57 assumes an expanded mesh arrangement as shown in Figure 7b.
  • the portions of material 61 which remain between the openings 63 provide strand means which will engage with the goods 5.
  • the strand means depicted in the embodiments of 7a and 7b can be used to replace the strand means previously described and may also be incorporated into the apparatus shown in Figure 5 so that packaging with strand means of this type will be produced.
  • Figures 8 through 10 show further embodiments of packaging within the scope of the present invention, which can be produced by suitably modifying the apparatus shown in Figure 5.
  • Figure 8 shows an embodiment where the goods 5 are totally suspended within the packaging within a mesh bag 65.
  • the bag 65 is stretched and held relative to the packaging by being sealed between the lid 3 and the base 1 as shown.
  • the bag 65 may have mesh of the same size as that previously disclosed in Figure 4.
  • the bag may not be a bag as such, but may be two separate webs of mesh material which are brought together as the lid 3 is closed relative to the base 1 so that the goods 5 are enclosed within a bag-like mesh.
  • the gas which is in the package, can freely circulate between spaces 67 and 69 through the mesh and can also contact the surfaces of the goods 5.
  • Figure 9 shows a different embodiment where a mesh web of the same type as that shown in Figure 4 is used, but here the mesh web is brought down and sealed to the bottom of the base 1 at positions 71 by a suitable heat sealing member or other sealing member (not shown). In this way, the mesh tightly holds the goods 5 relative to the bottom of the base 1 and inhibits flopping around of the goods 5 within the packaging.
  • Figure 10 shows an embodiment similar to that of Figures 1 through 3 but instead of the lid 3 being heat sealed relative to the base 1, it is sealed by having continuous extending snap engaging means 71 and 73 on the lid 3 and the base 1 respectively which co-operate to permit the lid 3 to be snap-lock engaged with the base 1 and to effect a gas tight seal therewith.
  • a web of mesh material of the type disclosed in Figure 4 can be provided over the goods 5 to provide the strand means 7 to hold the goods 5 relative to the base 1.
  • the impulse heat sealing means which seals the lid 3 relative to the base 1 can be dispensed with, although it may be preferable to effect heat sealing of the lid 3 to the base 1 to prevent unauthorised tampering of the packaging which may otherwise go undetected by an intending purchaser.
  • packaging where there is provided a base 1 of the type previously disclosed and a lid 3 of the type previously disclosed but wherein the lid 3 has a downwardly extending circumferential rib 74 to which may be bonded a web of mesh material having the configuration as shown in Figure 4.
  • a plurality of strand means 7 are provided across the lid 3 from the rib 74.
  • the web may be bonded at positions 15 so that it is carried integrally with the lid 3.
  • the goods 5 may be placed somewhat below the lip 11 on the base 1 and the dimensioning of the rib 74 is such that the strand means 7 are caused to still stretchingly engage with the upper surface of the goods 5 to hold the goods 5 relative to the packaging.
  • the strand means may be sealed to the base at a strand sealing station and then the base and the strands passed to a lid sealing station where the lid can be sealed to the base with a desired gas sealed between the lid and the base to enhance the keeping properties of the packaged goods such as red meats.
