Abstract
A frangible line defines a line of severance by extending across a carton wall that has a seam. The frangible line is extensively weakened along a predetermined segment where it traverses the seam. Preferably, the predetermined segment is extensively weakened by substantially disjoining the panel regions on either side of the line. Disjoinder is preferably achieved by making the predetermined segment a cut line.
Claims36
A severable carton wall comprising:
- a composite wall formed from panels joined along a seam;
- and
- a frangible line extending across the composite wall, traversing the seam, defining a line of severance;
- wherein a segment of the frangible line that traverses the seam is extensively weakened.
A removable carton trough comprising:
- a substantially tubular carton having at least one end region terminating in a composite end wall having a seam;
- and
- a separable trough formed from a portion of the end region hingably and severably connected to the end wall along a frangible line that traverses the seam;
- wherein a segment of the frangible line that traverses the seam is extensively weakened.
A blank for forming an erected carton having a severable carton wall, the blank comprising:
- a plurality of panels for forming a composite wall joined along a seam in the erected carton;
- and
- a frangible line extending across the panels disposed for defining a line of severance traversing the seam;
- wherein a segment of the frangible line that is disposed for traversing the seam is extensively weakened.
A blank for forming a carton having a removable carton trough, the blank comprising:
- a plurality of panels
- for forming a substantially tubular carton defining at least one end region terminating in a composite end wall having a seam;
- and
- for forming a separable trough from a portion of the end region hingably and severably connected to the end wall along a frangible line that is disposed for traversing the seam;
- wherein a segment of the frangible line that traverses the seam is extensively weakened.
