Abstract
A method for removing material between the panels of a foldable blank (100), includes the steps of: separating at least a portion of the blank with a contoured line (25) to define a first panel (15) and a second panel (20), terminating the contoured line at a vertex (V), selecting one of the first and second panels as a trimmed panel (15) from which material is to be removed, defining a first line (R) that includes a pair of first and second points (P1, P2) on an edge of the trimmed panel, and removing a portion (A) of the trimmed panel defined by the first line and a section of the edge lying between the first and second points.
Claims12
A method to remove material from a carton blank to prevent interlocking of a first panel with a second panel, comprising:
- cutting a carton blank, wherein a contoured cut line at least partially separates said first panel and said second panel and allows at least one of said panels to be displaced in a direction of displacement along the plane of said panels;
- and
- selecting one of said panels as a trimmed panel from which material is to be removed;
- and
- defining at least one boundary line that shares a first point and a second point with an edge of said trimmed panel;
- said boundary line being defined based on said direction of displacement of said at least one of said panels;
- defining a perimeter of an area to be removed by said boundary line and a section of said edge that lies between said first point and said second point, and
- removing at least said area from said trimmed panel.
A method for removing material between the panels of a foldable blank, comprising:
- separating at least a portion of said blank with a contoured line to define a first panel and a second panel;
- terminating said contoured line at a vertex;
- selecting one of said first and second panels as a trimmed panel from which material is to be removed;
- defining a first line that includes a pair of first and second points on an edge of said trimmed panel;
- and
- removing a portion of said trimmed panel defined by said first line and a section of said edge lying between said first and second points.
A blank for forming a carton, comprising a side panel, an end panel and a handle panel disposed adjacent to one of said side and end panels, said handle panel and said at least one panel being separated at least partially by a contoured cut line for defining an upper edge of said at least one panel, wherein said handle panel has a lower edge defined in part by said contoured cut line and in part by an opening defined between said lower edge of said handle panel and said upper edge of said at least one panel.
