  • cartons have been used to facilitate storing and transporting a variety of articles.
  • wraparound style cartons having an open-ended tubular structure that defines an internal space for collectively receiving a plurality of articles such as generally cylindrical cans.
  • FIGs. 1 and 3 A typical conventional carton having a tubular structure is shown in FIGs. 1 and 3 of Japanese Unexamined Patent Application, First Publication No. 2003-34354.
  • the carton disclosed in the publication has a top wall, a pair of side walls, and a bottom wall.
  • the opposed open ends of the tubular structure are provided with article retaining means for retaining articles in the tubular structure.
  • the article retaining means includes a top cover panel connected to an end edge of the top wall, a first side cover panel connected to the top cover panel via a fold line, a second side cover panel connected to the first side cover panel via a fold line, and a fold-back panel connected to the second side cover panel via a fold line and to the end edges of the respective side wall.
  • the article retaining means covers upper ends of one or more of the end articles that faces the respective opening of the tubular structure, to hold the articles in the tubular structure.
  • One solution to the aforementioned issue include to substantially increase the size of the fold-back panel such that the surface area of the fold back panel pressed on the articles in the tubular structure is substantially increased.
  • Such an approach requires use of a larger amount of paperboard material, which would result in substantial increase of the product price.
  • the present invention provides a carton blank and a carton which can improve strength to reliably hold articles to be received in a tubular structure and which can improve the aptitude to assembly using a machine.
  • the carton blank of the invention comprises wall panels for providing top, side, and bottom walls of a tubular structure.
  • the wall panels are disposed in a line to form the tubular structure.
  • the tubular structure has opposed open ends and is designed to receive one or more articles.
  • the blank further comprise at least one section for forming at least one article retaining structure for retaining the one or more articles in the tubular structure.
  • the at least one section is connected to respective end edges of two or more of the wall panels.
  • the at least one section includes a fold-back panel that is hingedly connected to an end edge of first one of the wall panels.
  • the fold back panel is adapted to be folded inward of the tubular structure when the blank is erected into a carton.
  • the at least one section further includes a cover panel that is hingedly connected to the fold-back panel and hingedly connected to an end edge of a second one of the wall panels adjacent to the first wall panel.
  • the cover panel covers a portion of an article in the carton when the blank is erected and loaded with one or more articles.
  • the end edge of the fold-back panel to which the cover panel is connected is provided with at least one tab that protrudes into the cover panel.
  • the tab may be formed by a cut in the cover panel so that it is substantially struck from the cover panel.
  • the tab protruding from the fold-back panel abuts against the peripheral surface of the article to be received.
  • the area of the fold-back panel that abuts against the article to be received is substantially increased.
  • the chance of the fold-back panel's slipping out of the tubular structure may be decreased.
  • the chance of the fold-back panel's easily breaking under pressure is also decreased.
  • the tab is formed at a position spaced apart from the adjacent open end of the tubular structure, the cut does not reach the adjacent open end. This arrangement is an additional feature that contributes to the strength of the carton formed from the blank of the invention.
  • the at least one section comprises two or more sections for providing two or more article retaining structures when the blank is erected.
  • the fold-back panels of the two or more sections may be hingedly connected to the opposed end edges of the first wall panels.
  • the cover panel of the at least one section may be provided at only one end edge of the fold-back panel and to a second wall panel adjacent to the first wall panel.
  • the cover panel may be provided at each of the opposed end edges of the fold-back panel.
  • One of the cover panels connected to the same fold back panel may be connected to the respective wall panel adjacent to one side edge of the first wall panel while the other of the cover panels may be connected to the respective wall panel connected to the other side edge of the first wall panel.
  • the present invention also provides a carton which comprises a top wall, a pair of opposed side walls, and a bottom wall connected together to form a tubular structure having opposed open ends.
  • the carton is adapted to receive one or more articles therein.
  • the carton further comprises at least one article retaining structure provided at at least one of the opposed ends of the tubular structure for retaining one or more articles in the tubular structure.
  • the at least one article retaining structure includes a fold-back panel hingedly connected to an end edge of one of the opposed side walls and folded inward of the tubular structure, and a cover panel hingedly connected to an end edge of the fold-back panel and hingedly connected to an end edge of one of the top and bottom walls.
  • the cover panel When the carton is loaded with one or more articles, the cover panel covers a portion or portions of the one or more articles in the carton.
  • the end edge of the fold-back panel to which the cover panel is hingedly connected is provided with at least one tab that protrudes from the fold back panel in the direction away from the cover panel.
  • the tab is formed at a position spaced apart from the adjacent open end of the tubular structure.
  • the tab and the fold-back panel together extend inward of the tubular structure t such that the tab is disposed between the one side wall and the one or more articles in the carton.
  • the tab protruding from the fold-back panel abuts against the one or more articles.
  • the area of the fold-back panel that abuts against the article is substantially increased. Accordingly, the carton of the invention can decrease the chance of the fold-back panel's slipping out of the tubular structure as well as of the fold-back panel's easily breaking or tearing. Additionally, since the tab is formed at a position spaced apart from the adjacent open end of the tubular structure, the cut that defines the tab does not reach the open end. This also decrease the chance of the fold-back panel's breaking or tearing staring at the open end.
  • the area of the fold-back panel that abuts against the peripheral surface of the one or more articles in the carton is increased so that the fold-back panel formed with the tab is more securely retained at its folded position between the respective side wall of the carton and the one or more articles in the carton.
