  • FIG. 1 shows a pack of smoking articles 1 manufactured using an apparatus and method of the present invention.
  • smoking articles 2 will hereafter be referred to as "cigarettes 2"
  • the pack 1 comprises a bundle of cigarettes 2 wrapped in an outer barrier layer 3.
  • the outer barrier layer 3 is sealed around the bundle of cigarettes 2 to provide an air-tight package enclosing the cigarettes 2.
  • the elongate side edges of the pack 1 are formed as fin seals as part of the air-tight sealing configuration of the barrier layer 3.
  • the outer barrier layer 3 also includes a one-way valve 4 on the outer surface of the pack 1 configured to allow air to be drawn out of the pack 1 to establish a negative pressure within the pack 1, but to prevent air returning back into the pack 1.
  • the pack 1 includes a cigarette access aperture (not shown) which is formed by a flap cut from the barrier layer 3 and which is covered by a re-sealable label 5.
  • the re-sealable label 5 makes a substantially air-tight seal with the barrier layer 3.
  • the one-way valve 4 comprises a pad 6 bonded around its perimeter over a small aperture 7 in the barrier layer 3, and including moveable flaps 8 that rest against the surface of the barrier layer 3 beneath the pad 6.
  • a vacuum source is applied to the valve 4
  • air is drawn from within the pack 1 through the small aperture 7 in the barrier layer 3, and the flaps 8 lift away from the barrier layer 3 slightly to allow the air to exit the pack 1.
  • the negative pressure within the pack 1 pulls the flaps 8 tight against the underlying barrier layer 3 to make a seal therewith which prevents any ambient atmosphere from being able to pass back into the pack 1.
  • the pack 1 is sufficiently sealed to allow the reduced pressure to be maintained within the pack 1 until the pack 1 is opened for the first time by lifting the re-sealable label 5 to open the access aperture.
  • the partial vacuum provided within the pack 1 helps preserve the flavour and freshness of the cigarettes during transport, storage and retail display until purchased by a consumer for use.
  • ambient air rushes into the pack to equalise the negative pressure, which gives an audible indicator to the consumer of the first opening of the pack l.
  • the material of the barrier layer 3 is substantially gas-impermeable and may, in particular, be impermeable to oxygen to prevent ingress of oxygen into the pack 1. Also, the gas-impermeable material of the barrier layer 3 prevents movement of moisture through the barrier material, so the moisture content within the pack 1 remains constant and is not affected by external conditions.
  • FIG. 2 shows a schematic view of a pack manufacturing apparatus 10 of the present invention, and shows the production process steps.
  • the apparatus 10 comprises an inner frame station 11, a barrier wrap station 12, a lifting station 13, a transfer wheel 14, a packing station 15 and an outer wrap station 16.
  • the inner frame station 11 receives generally cuboidal bundles of cigarettes 2 and flat card inner frame blanks 17.
  • the inner frame blank 17 is folded around the bundle of cigarettes 2, to form a combined inner frame and cigarette bundle 18.
  • the inner frame blank 17 is folded around the cuboidal bundle of cigarettes so as to extends at least partially extend over both the front and rear faces of the bundle, that is the largest faces of the cuboidal bundle.
