Definitions

  • the present invention relates to a wrapped package of consumer goods, comprising an outer wrapper including at least one diagonally extending line of weakness.

  • consumer goods in a variety of types of container.
  • Certain consumer goods are packaged in containers formed from folded laminar blanks.
  • elongate smoking articles such as cigarettes and cigars
  • hinge lid packs having a box for housing the smoking articles and a lid connected to the box about a hinge line extending across the back wall of the container.
  • Other types of consumer goods in particular fragile or breakable goods, are packaged in rigid containers formed of a moulded plastic or metal material.
  • consumer goods may be packaged in a bag, pouch or 'soft' pack formed of a flexible material, such as paper or cellophane.
  • the application of a tear tape to the outer wrapper of a filled container requires the implementation of additional process steps and apparatus in the production.
  • the tear tape is also typically formed of a different material to the outer wrapper, so that additional materials are required in the production of the packaging.
  • additional imaging apparatus may also be required as part of the quality control process, in order to detect any defects in the tear tape which may prevent the effective opening of the outer wrapper.
  • WO-A-98/2931 1 describes a carton including a number of packs of smoking articles.
  • the carton is wrapped in an outer wrapper including a plurality of parallel, spaced apart lines of perforation extending around the perimeter of the carton, at the interfaces between adjacent packs.
  • the lines of perforation therefore allow the consumer to remove or separate one or more individual packs from the carton by splitting the outer wrapper along the lines of weakness.
  • the outer wrapper includes a tear tape, it can be difficult for the consumer to remove the remainder of the outer wrapper from the separated packages.
  • novel way of opening could be incorporated into an outer wrapper without the need for additional or specialised apparatus or techniques to be incorporated into the process of wrapping the package. It would further be desirable if the novel way of opening the outer wrapper could be incorporated into an outer wrapper without adversely affecting the quality or robustness of the packaging of the consumer goods.
  • a wrapped package of consumer goods comprising: a filled package containing two or more consumer goods in contact with each other along an interface; and an outer wrapper, wrapped around the filled package such that first and second opposed edges of the outer wrapper overlap with each other in a longitudinal direction along the package.
  • the outer wrapper is provided with at least one line of weakness extending
  • the at least one line of weakness extends across the interface between the consumer goods.
  • consumer goods is used throughout the specification to refer to any type of good or item that may be sold to a consumer.
  • the term additionally encompasses containers
  • the consumer goods within the containers may in some cases be further wrapped or packaged, either individually or in groups of consumer goods.
  • the term "package” is used to refer to one or more packed or unpacked consumer goods that are wrapped with an outer wrapper.
  • the package may comprise 10 separate containers, each containing a number of consumer goods.
  • 25 package is a package comprising 10 containers of 20 cigarettes each.
  • Another example of such a package is a package comprising two cartons, each carton containing 10 containers of smoking articles.
  • the package may comprise two or more individual consumer goods wrapped together with the outer wrapper.
  • An example of such a package is a package of 10 individual CD or DVD cases, each including one or more CDs or DVDs,
  • the term “longitudinal” refers to the direction defined by the overlapping region of the opposed ends of the outer wrapper. Preferably, the opposed ends are sealed to each other in order to form a longitudinal seam.
  • the term “transverse” refers to the direction that is substantially perpendicular to the longitudinal direction of the overlapping region. For a 35 rectangular parallelepipedal package, the longitudinal direction will typically coincide with the direction in which the package is longest, but this need not always be the case.
  • the term “generally diagonally” is used to describe a line of weakness which has an overall extension in a diagonal direction that is greater than zero degrees and less than 90 degrees to the longitudinal direction. This means that the line of weakness extends simultaneously in both the longitudinal and the transverse direction.
  • the angle between the line 5 of weakness and the longitudinal direction may be measured as the angle between the projections of the lines of weakness and the longitudinal direction onto a common plane.
  • the line of weakness may be a continuous, straight line extending in the diagonal direction.
  • the term "generally diagonally” is used to indicate that the invention also encompasses embodiments in which the line of weakness is at least in part non-linear such that i o it extends diagonally overall, but not all parts of the line of weakness are extending in the same, diagonal direction.
  • a straight line extending between the two end points of the line of weakness would be diagonal, although the line of weakness may not be straight or diagonal along all of its length.
  • the line of weakness may be wavy, sinusoidal or zig-zag in shape so that the line of weakness changes direction either uniformly or non- 15 uniformly, continuously or non-continuously, whilst still achieving a general extension in the diagonal direction.

  • 20 outer wrapper at two or more positions through the breakage of the at least one line of weakness provides an effective way to split the wrapper so that it can be more easily taken off the package in order to access the consumer goods.
  • the diagonal direction of the line of weakness also ensures that once the wrapper has initially been torn along at least a part of the line of weakness, the tear line will more easily propagate around the package in order to

  • a line of weakness is considered to extend across an interface between consumer goods when the line of weakness crosses the virtual line of interface at the surface of the package, rather than extending along the line of the interface.
  • a line of interface between 35 consumer goods may extend around two or more faces of the wrapped package, depending on the number of packages that are wrapped together within the wrapped package. In certain embodiments, the line of interface extends all of the way around the package. It has been found advantageous to provide the at least one line of weakness so that it crosses the line of interface and does not follow the same line as the line of the interface between adjacent consumer goods. This reduces the risk of the outer wrapper inadvertently breaking along the interface during transport or handling of the wrapped package, which could cause adjacent consumer goods to split apart from each other. By registering the at least one line of weakness so that it does not coincide with the interface between adjacent consumer goods, a more robust packaging is provided which will be more capable of withstanding the forces to which the filled package may be subjected during handling prior to sale.
  • the positioning of the at least one line of weakness so that it does not coincide with the interface facilitates the unwrapping of the two or more consumer goods in a single step.
  • the splitting of the line of weakness may allow for the easy separation of the consumer goods from each other.

  • the unwrapping of the two or more consumer goods in a single step is further facilitated.
  • the arrangement of the at least one line of weakness in the outer wrapper of filled packages of the present invention enables the at least one line of weakness to be broken when the two consumer goods in contact along the interface are twisted relative to each other about an axis normal to the interface. With this twisting motion, the outer wrapper can be split apart along the at least one line of weakness such that the outer wrapper can be removed from all of the consumer goods within the filled package in a single step. This enables easy and convenient access to all of the individual consumer goods within the wrapped package.
  • the interfaces between the consumer goods lie in the longitudinal direction of the package or in the transverse direction, or both.
  • the diagonally extending lines of weakness will always cross the line of the interface rather than extending along the interface.
