Definitions

  • the present invention relates to a bundle of consumer goods comprising a wrapper having a sealed fold forming at least part of a wrapper side wall.
  • the present invention also relates to a method of forming the bundle of consumer goods.
  • Consumer goods such as smoking articles are commonly packaged in rigid box shaped containers, such as hinged lid containers having a box portion and a lid connected to the box about a hinge line extending across the rear wall of the container, a so called Flip-Top ® box.
  • the container further includes an inner frame wrapped around at least a portion of the consumer goods. This may provide further rigidity to the container and protect the consumer goods. Where the inner frame extends above an upper edge of the box portion, the inner frame also provides a surface against which the lid can close.
  • the consumer goods may be provided within an inner bundle that is housed within the box portion and the lid. Indeed, typically, for cigarette packs, the inner bundle is produced by folding an inner liner around a charge of cigarettes.
  • the folded inner liner may be desirable to seal around the cigarettes, preferably forming a hermetic seal.
  • the corners of the folded inner liner are typically formed using so called envelope folds, which are simple to form, but which result in many layers of overlapping material at each corner of the inner liner. Such folds are difficult to seal adequately and it may be difficult or impossible to achieve a hermetic seal, particularly on high speed production lines.
  • the present invention provides a bundle of consumer goods, the bundle comprising a wrapper wrapped around one or more consumer goods.
  • the wrapper is formed from a single laminar blank and comprises a first end wall and a second end wall opposite the first end wall.
  • the wrapper further comprises a first side wall formed from a single panel, wherein a first edge of the first end wall depends along a fold line from a first edge of the first side wall and wherein a first edge of the second end wall depends along a fold line from a second edge of the first side wall.

  • panel refers to a portion of the wrapper formed from a single, continuous portion of material.
  • a panel may depend along one or more fold lines from one or more other panels.
  • overlap refers to a panel that depends along only one fold line from only one other panel.
  • wall refers more generally to a facet of the folded wrapper, and a wall may be formed from a single panel or flap, or a wall may be formed from two or more abutting or overlapping panels or flaps.
  • fold line refers to a fold between two adjacent panels, wherein the fold has a length of at least about 2 millimetres.
