Definitions

  • the present disclosure relates to packaging and, more particularly, to article packaging, packaging methods, and blanks for forming article packaging.
  • cartons are often used for packaging or otherwise containing one or more articles, such as a group of articles. Such cartons may also be used as carriers that are useful for enabling consumers to transport, store, and access the articles for use or consumption. Additionally, in some circumstances, the same carton may be used for shipping and/or display of the articles by a retailer. However, traditional cartons, or carriers, may permit the articles packaged therein to move relative to the carton. Such movement may result in the articles having an undesirable location or orientation relative to the carton.
  • cartons or carriers For cost and environmental considerations, such cartons or carriers need to be formed from as little material as possible and cause as little wastage in the materials from which they are formed as possible. Further considerations are the strength of the carton and its suitability for holding and transporting a weight of grouped articles. It is desirable that the contents of the carton are securely held by the carton and that the cartons or carriers are easy for a consumer to grasp and carry.
