Definitions

  • the invention relates to cartons, and more particularly, to a carton for enclosing multiple articles that includes a detachable portion for facilitating removal of the articles.
  • Cartons for encasing multiple articles are useful for enabling consumers to obtain and transport a desired quantity of individual articles such as soft drinks or other beverages.
  • a consumer frequently desires to remove one article from the carton at a time. It is known to provide a carton having a detachable portion for removing articles, which is provided when part of the carton is substantially detached or torn away from the carton to expose articles for removal.
  • a problem associated with such cartons is that a user can have difficulty in accessing articles through an opening provided by the detachable portion of the carton. Furthermore it can be difficult to see how many articles remain within the carton and such a carton is only suitable for dispensing the end most articles, which may not be desirable for use with cartons containing a variety of items.
  • the various embodiments of the present invention overcome the shortcomings of the prior art by providing a carton with a detachable portion.
  • the detachable portion can be detached to provide an access opening that facilitates visibility of and accessibility to articles within the carton without compromising the structural integrity of the carton.
  • the carton includes a tubular structure including a top wall, a bottom wall, and opposing side walls.
  • First and second end walls are formed at the open ends of the tubular structure such that the end walls are connected to the top wall, the bottom wall, and the side walls.
  • a detachable portion of the carton is defined by a severance line to include at least a portion of the top wall, at least a portion of the first end wall, and a portion of the side walls.
  • the top wall portion of the severance line is offset from the second end wall by a certain distance such that a portion of the top wall of the carton remains to provide structural integrity after the detachable portion is removed.
  • the offset distance is also determined such that articles in the carton are viewable and easily accessed.
  • the minimum distance between a top wall portion of the severance line and the second end wall is no greater than half of the distance between the first and second end walls.
  • the top wall portion of the severance line is substantially closer to the second end wall than to the first end wall.
  • the top wall portion of the severance line may be curved or otherwise contoured, in which case, the minimum distance between the top wall portion of the severance line and the second end wall is less than the distance between the first and second end walls.
  • the carton includes a tear initiation feature that is at least partially defined by the top wall portion of the severance line.
  • the tear initiation feature can be located between the top wall portion of the severance line and either the first end wall or the second end wall.
  • the tear inititation feature facilitates breaking the severance line to detach the detachable portion.
  • FIG. 1 is a plan view of an exemplary embodiment of a blank for forming a carton, according to the present invention.
  • FIGs. 2 and 3 are perspective views of a partially erected carton formed from the blank of FIG. 1 , showing steps for forming the end closure structures of the carton.
  • FIG. 4 is a perspective view of a fully erected carton formed from the blank of FIG. 1.
  • FIG. 5 is a perspective view of the carton of FIG. 4 showing a tear initiation tab being displaced into the carton.

  • FIG. 1 illustrates certain of the various aspects of exemplary embodiments of a carton including a detachable portion to facilitate the removal of articles from the carton.
  • the carton is defined by a top wall, a bottom wall, side walls, and first and second end walls.
  • the detachable portion is defined by a severance line that extends across at least the side walls, top wall, and first end wall of the carton.
  • the top wall portion of the severance line is spaced apart from the second end wall by a minimum distance that is no greater than half the distance between the first end wall and the second end wall.

Abstract

L'invention concerne un carton (200) comprenant une paroi supérieure (214), une paroi inférieure (218), des parois latérales opposées (212, 216) et des première et seconde parois terminales (220, 222). Une partie amovible (210) du carton (200) est définie par une ligne de séparation (180) permettant de comprendre au moins une partie de la paroi supérieure (214) et une partie des parois latérales (212, 216). La partie de la paroi supérieure (182) de la ligne de séparation (180) est espacée de la seconde paroi terminale (222) d'une certaine distance (D1), de manière qu'une partie de la paroi supérieure (214) reste afin de conférer une intégrité structurelle au carton (200) une fois la partie amovible (210) retirée. La distance (D1) est également déterminée de manière qu'on puisse voir facilement les articles (B) contenus dans le carton (200) et accéder facilement à ceux-ci. La distance minimale (D1) entre une partie de la paroi supérieure (182) de la ligne de séparation (180) et la seconde paroi terminale (222) n'est pas supérieure à la moitié de la distance entre les première et seconde parois terminales (220, 222).
