Definitions

  • the invention relates to a container and a blank for a container, and more specifically but not exclusively, to a sandwich container and a blank for a sandwich container.
  • Sandwiches and other convenience foods are often pre-prepared and presented in packaging ready for purchase.
  • the packaging used is usually manufactured from either a plasties material or from paperboard.
  • 'paperboard' is considered to encompass paper, cardboard and similar materials.
  • paperboard containers are preferable from an environmental standpoint. Company specific graphics, logos and trademarks can also be applied during the manufacturing process far more easily than for plastic containers. Nonetheless, plastic containers remain popular because they are generally capable of forming a better seal and thereby prolonging the shelf life of the product contained therein.
  • plastic containers remain popular because they are generally capable of forming a better seal and thereby prolonging the shelf life of the product contained therein.
  • paperboard containers folded from blanks struggle to achieve a good airtight seal.
  • the paperboard is also susceptible to damage from grease, fat or other liquids in the food products. If grease is allowed to soak into the paperboard, then both the outward appearance and the structural integrity of the container is compromised. Even with the inclusion of a barrier coating, the shelf life of products in such containers is limited to around forty eight hours. This is because cut edges (i.e.
  • webbing sections as opposed to tabs to form the join between abutting walls of the blank have been beneficial in creating a more effective seal.
  • these webbing sections generally comprise two areas of paperboard with a fold line in between, each connected by a further fold line to one of two abutting walls.
  • the webbing sections fold like a concertina to lie flat against one of the walls.
  • complex techniques such as heat sealing or RF welding, and/or to cut away one webbing area so that it does not extend to the full height of the other.
  • the requirement for heat sealing or RF welding means that containers often have to be pre-formed from the blanks prior to shipping to customers. Any exposed cut edges lead to reduced integrity of the finished container, and further problems as discussed above.
  • a blank for assembly into a food product container having a webbing section between two panels which, when the blank is assembled, form two abutting walls of the container, the webbing section comprising two webbing portions with a fold line therebetween, one of said webbing portions comprising a discontinuity spaced from the fold line so as to allow bonding means to bond one of the abutting walls to the other one of said webbing portions when the blank is assembled.
  • discontinuity spaced from the webbing fold line allows the blank to be formed into a container and easily bonded together without the integrity of the seal being compromised.
  • the best seal is possible when the discontinuity takes the form of an aperture formed in at least one of the webbing areas.
  • the container With the discontinuity as described, it is possible to bond the container together using a standard adhesive. This is beneficial if the blanks are to be shipped to customers in an unassembled state, since they can be glued by customers using existing machinery. The blank may also be bonded, before or after shipping, by other means.
  • the fold lines which exist between panels of the blank are defined by creases rather than by scoring. A better seal can be achieved by the assembled container if this approach is taken.
  • a better sealing container is also achievable through the provision of a barrier coating on the blank.
  • This coating is preferably also susceptible to heat sealing and/or RF welding to enable the container to be formed by more than one method.
  • Suitable materials for the coating include but are not limited to plastics, for example polyethylene or acrylic.
  • the blank preferably folds into a substantially triangular prism with one open side, in particular into a container suitable for sandwiches.
  • the blank may fold into a substantially square tub shape, for containing noodles or similar.
  • the folded container may also comprise a flange portion around the opening and/or a folding lid which are formed as further panels of the blank.
  • a blank for assembly into a food product container having a webbing section between two panels which, when the blank is assembled, form two abutting walls of the container, the webbing section comprising two webbing portions with a fold line therebetween, the fold line being of such a length that, when the blank is assembled into a container, the end of the fold line is adjacent an opening of the container provided to receive food product.
  • the extension of the fold line to the opening of the assembled container eliminates cut edges from the inside of the container, thereby providing greater integrity.
  • the blank thus described may also benefit' from any of the previously mentioned features.
  • a third aspect of the present invention there is provided a method of forming a container from a blank as described above by applying adhesive to bond the panels and webbing portions.
  • a further aspect of the present invention provides a blank for assembly into a food product container comprising a substrate layer and a liquid impermeable layer, the liquid impermeable layer being applied over the entire substrate layer and forming a window over an aperture provided in the substrate layer.
  • the liquid impermeable layer is resistant to grease, fat and other liquids found in foods.
  • the layer is also preferably susceptible to RF welding and/or heat sealing.
  • Plastics materials for example polyethylene or acrylic, are suitable.
  • the substrate of the blank may be formed from paperboard.
  • the blank comprises one or more webbing sections between adjacent panels.
  • These webbing sections may comprise two webbing portions with a fold line therebetween, to aid folding of the blank.
  • one webbing portion comprises an aperture to allow access to the liquid impermeable film once the webbing sections are folded.
  • liquid impermeable coating may be applied before the final shape of the blank is cut and/or before fold lines and any apertures in webbing sections are formed.
  • the present invention also provides a method of forming a blank for a container, comprising the steps of forming a substrate, applying a liquid impermeable layer to said substrate, and cutting said substrate and liquid impermeable layer combination to shape.
  • a substrate may be formed coated with a heat sealable layer prior to cutting to shape to form a blank.
  • a method of forming a food product container comprising steps of folding a blank comprising a webbing section between two panels which, when the blank is assembled, form two abutting walls of the container, and bonding the webbing section to the outside of said container once formed.
  • Forming a container by the method described eliminates all cut edges from the interior of the finished container, minimising the chances of fat and oil ingress and, thereby, improving integrity of the container.
  • the webbing section may be formed from two webbing portions with a fold line therebetween. It is beneficial to the sealing of the finished container if these two webbing portions are bonded to one another before the webbing section is bonded to the container.
  • An aperture is preferably provided in one webbing portion, and is positioned, when folding the blank, against the outside of the container. Common bonding means may then be used to bond both webbing portions to the wall of the container.
  • the bonding is achieved by heat sealing, for example through the use of a heat sealable coating provided on one surface of the blank.
  • Modified tooling specific for the task in hand, will greatly simplify the container forming process.

  • a flange forming portion 111 is also provided around the edge of the blank 101 to form a flange when the container 107 is in its folded state.
  • the blank 101 of Figure 5 has a rectangular base panel 110 having a major and minor sides.
  • the larger wall panels 104 extend from each of the major sides of the base panel 110.
