Definitions

  • This invention concerns a packaging element, for erection into a container, comprising at least one layer of stiff material lined on at least one side with a thin flexible material, said stiff material comprising a base element having end flaps on opposed ends thereof, side elements franking the base element, said side elements having gussets on opposed ends thereof which gussets extend outwardly to substantially the same extent as the end flaps of the central base element, and a lid element flanking one of the side elements.
  • 4056221 discloses a packaging element formable into a container which has an integrally-formed plastics liner having also an external plastics layer.
  • the liner and external plastics layer totally enclose the stiffening cardboard material and a fluid-tight but open container is formable from the packaging element.
  • 2430610 is of the kind defined and the first paragraph of this specification and comprises gussets that are triangular and positioned so that there exist first substantially triangular areas of thin flexible material devoid of stiff material between the adjacent end flaps and the gussets, said lid element having triangular gussets on opposed ends thereof which gussets extend outwardly to substantially the same extent as the end flaps of the central base so that there exists a respective second substantially triangular area of thin flexible material devoid of stiff material adjacent each of the gussets of the lid element, parallel folding seams being provided between each of the adjacent base, side and lid elements and between the end flaps and the gussets, the arrangement and construction being such that upon folding the end flaps and gussets upright relative to the base, side and lid elements about said folding seams and folding the side elements relative to the base element so that they are upright relative to the base element, the respective first triangular area is accommodated between the corresponding gussets fixed to the respective side element and the corresponding
  • the pre-characterising portion of claim 1 is based on this prior art.
  • This container does have an integrally formed closure, but it is provided by a single lid element flanking one only of the side elements. Thus, it is not fluid-tight, nor is it of a self-supporting configuration in its erected, but open, pre-loading condition.
  • the present invention achieves this object by provision of such an arrangement characterised in that there is a respective said lid element flanking each of the side elements and in that there is a border of thin flexible material all around the layer of thin material so that when said side elements are upright, portions of the adjacent second triangular areas overlap and can be joined to retain the erected packaging element in a condition for filling with the side elements, lid elements and gussets all upright with respect to the base element so that a container is formed having a single opening thereto, and by extending said opening transversely, the free edges of the lid elements and adjacent gussets are drawn together for sealing.
  • a packaging element generally indicated by arrow 1 and according to the example illustrated comprises a first layer 2 of plastics material, a second layer stiff material such as cardboard 3, and a third layer of plastics material 4.
  • the plastics layers 2 and 4 are adhered to the stiff material 3 and to each other where there is not contact with the cardboard 3.
  • the first and third layers 2 and 4, in plastics, can be co-extruded film comprising a sandwich of EVA film and LDPE film.
  • the EVA has a low melting point and is in contact with and adheres to the cardboard 3 and the other plastics layer.
  • the second layer 3 of stiff material comprises a centre section 5 and two side sections 6, and the side sections 6 are spaced from and positioned at equal distances from the ends of the centre section 5.
  • the packaging element can be formed into a container with a base 5, sides 6, and ends formed from extending parts 5A of the section 5 (a bend in the cardboard being made along the broken lines 7), corners being gussetted and sealed or otherwise joined.
  • the plastics layer 2 and 4 can be single sheets of plastics, adhered to the stiff material by a suitable adhesive.
  • the stiff material forming the centre and side sections may optionally be a unitary member (not shown) with sides 6 foldable about seams.
  • FIG. 2 of the drawings illustrates an apparatus for making the packaging elements of Figure 1.
  • the apparatus illustrated comprises a conveyor 8 positioned upstream from a pair of rollers 9 and 10, fed with plastics film 11 from a supply source indicated by arrow 12.
  • the centre spacings of the rollers 9 and 10 can be adjustable to suit the thickness of the packaging element.
  • Stiffening material 13 is placed on the conveyor 8, which stops, receives the stiffening material 13 and then feeds the same between the rollers 9 and 10.
  • the rollers 9 and 10 can be heated by a fluid such as oil such that the plastics adheres to the stiffening material and the adhesive process is further assisted as it passes through pinch rollers 14 (which can be covered with a soft material such as rubber or felt material) downstream of the rollers 9 and 10 which applies pressure to the top and bottom surfaces of the packaging element as it passes betweem them.
  • a rotating hot or cold knife 15 can be positioned downstream of the rollers 14, such being designed to perforate or cut (see broken line of Figure 1) the plastics material to make one element easily separable from the element following. Box-making collection and forming plant at 16 complete the process for forming the packaging elements into a container.
  • the inner layer (which may be EVA plastics) is softened during the manufacturing process and becomes, in effect, an adhesive.
  • the conveyor 8 and the pinch rollers 14 are optional.
  • Figures 3 to 7 of the drawings illustrate one possible embodiment of a packaging element in accordance with the present invention, the element generally indicated by arrow 17 being formable into a container (generally indicated by arrow 18 and illustrated by Figure 7), said container having a base 19 and sides 20 and a lid section generally indicated by arrow 21.
  • the packaging element comprises a first layer of plastics 22, a second layer of stiff material 23 and a third layer of plastics material 24, said first and third layers 22, 24 being adhered to the stiff material 23 and to one another where they overlap.
  • a border 25, where there is surface contact between the plastics layers is provided about the periphery of the element 17.
  • the stiff material 23 comprises a substantially rectangular base 26 with flaps 27 foldable with respect to the base 26 and flaps 28 foldable with respect to the the flaps 27 such folding being made about seams 29.
  • Each of the flaps 27 and 28 are provided with gussets 30 and 31 and the base 26 is provided with end sections 32, the gussets 30 and 31 and end sections 32 foldable with respect to the flaps 27 and 28 and the base 26 respectively.
  • the gussets 30 are of a triangular shape defined by seams 33, a long side 34, and short side 35.
  • the gussets 31 are similarly shaped.
  • an additional strip 36 of stiff material is provided such being foldable about seams 37.
  • plastics to plastics contact between the first and third layers is provided at triangular areas 38 void of the stiff material.
  • the packaging element 17 of Figure 3 can be erected into the container 18 of Figure 7 in progressive steps as is illustrated by Figures 4, 5 and 6.
  • the first step (see Figure 4) is to fold the end sections 32 and the gussets 30 and 31 into an upright position with respect to the base 26 and flaps 27 and 28.
  • the next step in the erection of container 18 is illustrated by Figure 5 which shows the opposed flaps 27 and 28 being folded about seam 29 which is common with the base 26 such that gussets 30 overlap the outside end sections 32 of the element, and void areas 38A are accommodated between the gussets 30 and the end sections 32.
  • This later step is further progressed until the flaps 27 are perpendicular with the base 26 (see Figure 6) and at that point edges 39 of the border 25 overlap and can be adhered together by blocking, heat sealing or the like.
  • an inverted "T" shaped seal T is made binding together all adjacent overlying plastics layers.
  • a container ready to receive articles is thus formed, and overlapping and adjacent edges 39 have been utilised to secure the container in its erected position.
  • the container 19 can be filled and the ends of the top edges extended in the direction of the arrows 40.
  • Figure 7 illustrates the manner in which the lid 21 (formed from flaps 28 and gussets 31) can be sealed by the matching of the strip 36 to border portion 25a as the flaps 28 and gussets 31 lay flat (a natural consequence of movement of the lid section in direction of arrow 40), and finally the sealed container can be closed by folding down the flap formed by the joined border portion 25a and the strips 36, folding the triangular lid ends 41 formed from gussets 31 downwards in the direction of arrow 42, and fixing the lid ends to the base and/or the ends of the container.
  • the gusset tips 43 may be trimmed off at line 31 a when the stiff element is fabricated, and prior to the application of the plastics layers 22 and 24.
  • the packaging element 17 could have its base 26, and flaps 27 and 28 formed from separate pieces of material in a similar manner to the element of Figure 1. By so doing material savings can be made when the stiff material is pre-cut.
  • FIGS 8 through to 11 of the drawings illustrate a further embodiment of a packaging element in accordance with the present invention, which is somewhat similar to that illustrated by Figures 3 through to 7 of the drawings. For that reason equivalent components are denoted by the same numerals used with respect to the Figures 3 to 7 embodiment.
  • the main difference from the previously described embodiment is that the gussets 31 of the Figures 3 to 7 embodiment do not exist and in fact triangular gussets 44 are provided which are fixed about seam 29 of gussets 30 as shown.
  • the strip 36 from the previous embodiment is omitted.
  • a coardboard container can be formed with no flaps or joining strips in the cardboard material.
  • Containers in accordance with aspects of the present invention are substantially tamper-proof particularly if a tape such as EVA tape which is sealable against the outer edges of the container and/or lid is used.
  • a glue tape may also be used.
  • plastics is a fluid impervious material containers of the present invention are liquid impervious and can be made gas impervious by using a gas impervious material and one of the layers of a co-extrusion laminate.
  • suitable gas impervious materials are nylon, aluminium or PVDC.
  • the containers described can be conveniently made using co-extruded plastics it would be appreciated from the foregoing that a more suitable general description would be that the container walls are multi-laminates and optionally co-extrusions can be used.
  • a container can be formed having a hygienic non- fibrous surface of for example plastics material in a simple yet effective manner which will allow for example meat to be packed in an atmosphere free of cardboard fibres as the containers can be formed a substantial distance or indeed in a different factory to the place where they are filled.
  • all cardboard is contained within the first and third layers and therefor the risk of cardboard fibres being present in the atmosphere or otherwise coming into contact with meat products is substantially reduced.
  • the blanks can be preprinted and a lighter-weight, less rigid cardboard can be used and even re-cycled cardboard could be used.
  • fold lines are eliminated and these are thought to be the cause of problems at removal and thawing when containers are used to store food under refrigeration.
  • containers/cartons of the present invention are ideally suited for storage and cartage of foods (frozen, chilled or otherwise) it is to be appreciated that the containers may be used for any purpose whatsoever.
  • stiff material is provided with separate pieces or as a unitary member. Although this system has advantages it should be appreciated that the stiff material can be optionally provided in separate pieces, or as a unitary member with the various portions of stiff material foldable about a seam formed therein.
  • the flexible layers of material although most likely to be from plastics may be from other materials, such as sheet foil or the like.
